WHERE ANY ITEM CALLED FOR IN THE ITB DOCUMENTS IS SUPPLEMENTED HERE, THE ORIGINAL REQUIREMENTS, NOT AFFECTED BY THIS ADDENDUM, SHALL REMAIN 1N EFFECT. 1. For testing of the precast reinforced concrete pipe, will the test be to the 0.01 -inch crack limit or to the ultimate strength limit? Ans. The test for precast reinforced concrete pipe will be to the 0.01 -inch crack limit. 2. Request that all hydrocarbon resistant gaskets for all types of permissible pipe materials be of .� neoprene instead of nitrile rubber. Ans. No. Only one segment of proposed storm sewer pipe will be allowed to use neoprene gaskets for hydrocarbon resistance. This segment is Line Al, Station; 72+62 to Station 93+00; and is indicated for hydrocarbon resistant gaskets on Sheet G13 of the drawings. All other storm sewer segments that require hydrocarbon resistant gaskets must use nitrile rubber material as originally specified. 3. Request that specification Section 02533, paragraph 1.3.13 on page 1 be revised to require no more than three percent deflection no sooner than 30 days after installation, and no more than five percent long-term deflection. Also include in the revision that prior to final acceptance of the project the pipe is required to show no more than five percent long-term deflection. Ans. No revisions to the above referenced paragraph are being made with this addendum. 4. Specification Section 03300, Cast -in -Place Concrete, paragraph 2.1.A indicates that the form liner must be Urethane. Can single use form liner be substituted? Ans. Substitutions cannot be properly evaluated before bid opening because of a lack of data. The procedure for substitutions is covered in the Special Provisions, paragraph SP -8. "Substitute" and "or - equal" items will be evaluated after award. As an advisory to the Bidder, single use form liner will not be considered an, acceptable substitute item. 5. Will vertical construction joints be allowed at the corners on wall concrete for the inlet structures? Ans. Vertical construction joints at the corners of the inlet structures will probably be allowed provided that the joint conforms to the joint requirements in specification Section 03300. Water -tightness of the . joint will be a consideration, as well as whether adjustments to reinforcing steel placement and quantities are necessary. Submittals will be required showing proposed joint placement. 6. Will stay -in-place permanent metal deck forms be allowed for use to form the top slabs of the inlet structures? Ans. Yes. Stay -in-place metal deck forms will be permitted and shall be galvanized equal to G60 coating thickness, both sides. The edge of the metal deck shall not intrude into the finished appearance of any structure in which it is used. Submittals will be required. The thickness of the concrete slab shall not be reduced at any point through the use of a metal deck form, nor shall the metal deck's characteristics be considered for reductionof any reinforcing steel requirements. �.,, Page 1 of 4 7. Inlet Al on sheet C1 of the drawings incorporates a one-foot by one-foot beam into the top concrete slab. Will it be permissible to construct the beam first and leave a construction joint at the top of the beam between it and the top slab? Ans. Yes, a construction joint is permissible between the top of the beam and the underside of the _ top slab. Some reinforcement adjustment or addition may be necessary, but this will be considered after award. A submittal will be required. Also see Section 03300 of the specifications, paragraph 3.4 ' concerning construction joints. 8. There are a number of existing utilities to cross on this project, namely 6-inch and 8-inch water and sewer that serve the local neighborhoods. Is the City planning to temporarily cut and plug these utilities just ahead of the proposed storm sewer construction operations and then re-install after the storm sewer has been installed? Ans. There are no plans for the City of Lubbock Water Utilities Department to perform more than the water utility relocations noted on the plans and the temporary removal and re-installation of a fire hydrant noted in Addendum No. 1, paragraph 40. The capping of these lines would, in many cases, cut water and sewer from the residences and businesses. 9. On Line A2 near Stations 315+00, 318+00 and 321+50, the utility lines are close together. Why were these locations not specified for tunneling as at the locations at 292+00, 295+00 and 298+007 Ans. This question is addressed in Addendum No. 3, paragraph 35. 10. Is it required that Contractors bid on both projects, i.e. ITB 9001-OINK and 1713{#078=01%VK? 'The way that we read it, Bidders can bid on both or either one. Our reasoning is that ITB #078-01 NK is likely to be the lower priced of the two projects and that the Bidder's best option is to submit on only ITB #078-01 NK. Ans. The bidder will not be required to bid on both project ITB #001-01/VK and project ITB #078- 001NK. The Owner does suggest that the bidder review the bid evaluation procedures referred to in Addendum #4, paragraphs 13 and 14, for information on how the bids will be evaluated on these projects. 11. Requesting approval to substitute earthen dams in lieu of sheet piling in the shallow playa lakes. Ansa No. These lakes are the only source for drainage within the construction areas and must continue to have the capacity for handling rainfall events for the duration of the project. Also see Addendum No. 1, paragraph 35 and Addendum No. 3, paragraph 63. CITY-INITIATED OR ENGINEER-INITIATED ADDENDA 12.

Provide manufacturer's certificate of conformance to the specifications. The manufacturer shall provide load testing facilities for performing manufacturer's load tests in conformance roll with ASTM C655 or ASTM C76 as applicable, or shall'arrange for an independent laboratory r; to perform load tests. 1. Lot size shall be the total number of joints of pipe of a specific diameter to be supplied on ±** the project, regardless of D-Load, however the test shall not be run on a single D-Load of pipe if different D-Loads are being supplied for a single pipe diameter. If different diameters are supplied then there will be different lots and lot sizes. If different D-Loads are being supplied for a single diameter, then at least one representative joint of pipe for each D-Load must be included in the sample size even if it causes the number of samples to exceed the ASTM sample size. 2. Sample size for testing shall be in accordance with ASTM C655, paragraph 101 "Acceptance of Pipe by Load Testing" for each lot of pipe. Sampling and testing shall be for each size of pipe to be furnished for the project, however the sample size isnot based on each D-Load rating. For example, if the indicated ASTM sample size is 4 joints of 48- inch diameter pipe, the four joints of pipe need not be for the same reach of storm sewer ti or for the same D-Load. However, if three D-Loads are within the four-joint sample size, then at least one joint of each D-load rating must be included. 3. Sampling shall be at random in accordance with paragraph 4.1.1 of ASTM C655, provided . , that the D-Load representation specified herein is maintained. 4. Load testing for precast reinforced concrete pipe shall be to the formation of 0.01-inch crack. 5. Pipe that has been used in 0.01-inch crack load tests, meets the strength requirements, and is otherwise in conformance with the specifications, maybe used in the project. ■., B. Add the following to paragraph 2.4, page 2 of specification Section 02638: D. The Engineer and Owner shall be entitled to witness the load tests. The manufacturer must provide the Engineer with adequate advance notice of when and where the load tests will take _ place. The Engineer shall then make known whether or not the load tests will be observed. 15.

If groundwater is moved due to the Contractor's dewatering operations, who is responsible.if contamination is moved into the trench with the migrating groundwater? Will the Contractor be classified`as the generator? The Contractor will be changing the groundwater gradient with dewatering operations, i.e. producing a drawdown cone of depression in the water table. Ans. The owner of the LPST site is ultimately liable for introducing contamination into the groundwater. However, the City of Lubbock will take responsibility as the generator for legal purposes under the construction contract for migrating groundwater. -The Contractor its expected to treat contaminated groundwater from his dewatering operations down to applicable regulated concentrations prior to'release to surface waters or to the City sanitary sewer, for "those groundwaters that require treatment. 2. Is the only contaminant of concern gasoline? Ans. The contaminants of concern are petroleum products. This includes gasoline, diesel, kerosene, hydraulic lift oil, motor oil, etc. in the regulations. The only petroleum contaminants that the Engineer can identify from TNRCC records and limited personal knowledge ofthe sites'are from gasoline and diesel, although other petroleum sources (such as motor oil, etc. listed in this paragraph) could be present. The TNRCC records in the Engineer's possession are not specific about the type of product released. 3. Will the Texas Natural Resource Conservation'Comniission`(TNRCC)"`ortfie-EPA govern aspects dealing with petroleum releases? Ans. The City of Lubbock will govern discharges to the City's sanitary sewer system and'disposal'of contaminated soils at the West Texas Region Landfill. The TNRCC willgovern all other aspects of handling petroleum -contaminated soils and water. 4. How were the petroleum -contaminated material quantities for Lines A1,A2.. and A4 calculated? elk Ans. These quantities were calculated by determining the approximate limits within the project that have a higher potential for contamination as indicated by records on file with the`TNRCC, orthaf might be suspected as having the potential for contamination (see Engineer's interpretations and opinions attached to this addendum). Forthe quantity of potentially contaminated soil', the portion of the soil profile within the limits described above that potentially could have been in contact wifh`contaminated groundwater or free product were identified, and the volume of this potentially' contaminated strata of soil was calculated. For the quantity of contaminated groundwater, the portion of the storm sewer within the limits described above that is anticipated to be dewatered was taken as the calculated quantity. 5. Will the City of Lubbock provide temporary storage for contaminated soils that need to be stockpiled or remediated? Ans. The attached replacement Section 02111 specifies how contaminated soils of differing concentrations are to be handled. Page 1 of 4 6. Addendum No..1 for ITB #001 -OINK, paragraph 2 gives the Contractor the option to open cut a portion of Line Al -03 from approximate Station 9+50 to Station 18+24. If indeed the cost is lower, then the unit prices for the average unit price for tunneling will be lower, resulting in a savings for the City. The way that I read the addenda, if the Contractor open cuts this portion of line as described in Addendum No. 1 then the pay quantity will not be reduced and the Contractor can incorporate any savings in his unit price for tunneling. Is this a correct conclusion? Ans. No. Under state law, this is not possible in a unit price contract. If the Contractor elects to open cut the pipeline reach from Station 9+50 to Station 18+24, then the progress payment will reflect the quantity change. That is, the open cut portion will be added to the quantity for pipe installed under the contractor's option of method and that same quantity difference will be deducted from the tunnel/bore quantity. In other words, there will be an increase in the quantity paid under Bid Item 2 and a corresponding decrease in the quantity paid under Bid Item 3. Not knowing which Bidder will be awarded the contract, and whether that Bidder will open cut or tunnel that particular reach, the bid quantities can not be reasonably adjusted prior to bid. Therefore, it will be understood by the Owner that the option to open cut the reach from Station 9+50 to Station 18+24 will be accounted by the Bidder in the various bid items if the Bidder chooses to exercisethe,open cut option from Addendum No. 1, paragraph 2. 7. Including the quantity from Station 9+50 to 18+24 as tunneling, I calculate approximately 183 linear feet less of 72 -inch pipe in tunnel than what is shown in the revised quantities included in Addendum No. 1. Has a run of tunneling not been listed, or have I possibly made an error? Ans. The Engineer has found an error in the quantities included in the first page of Exhibit "A" in Addendum No. 1. One segment of pipe was double -accounted. A replacement bid form sheet is attached to this addendum and replaces the first page of the previous Exhibit "A" bid submittal. Directions for replacement are indicated in this addendum. The Bidder is, also cautioned not to simply take the differences in stations given on the profile notes of the plans when calculating lengths. The baseline on the drawings does not always correspond to the pipe centerline. Therefore, an error can be introduced in calculations using only differences between stations. 8. What if we run into contamination outside of the stations shown in the specifications? Ans. if it is petroleum contamination, then the unit prices established in the bid documents will be applied. Other contamination will have to be addressed based on the type of contamination. 9. Is the City of Lubbock going to provide temporary storage for the remediation sites? Ansa The Contractor will not be required to remediate petroleum -contaminated soils that exceed the_., concentrations that can go to the West Texas Region Disposal Facility. Soils that exceed the concentrations shown on the Texas Department of Health letter furnished with Addendum 11 will be delivered by the Contractor to the City's soil treatment facility located on the northbound frontage road of Interstate Highway 27 between Municipal Drive and Erskine Avenue. The soils delivered by the Contractor shall be placed by the Contractor into one of the treatment cells located there. The treatment cells are similar to drying beds and can be directly dumped into. 10. Will the City furnish locations for storage and remediation of soils and groundwater? Ans. The Contractor will not be required to remediate petroleum -contaminated soils that exceed the concentrations that can go to the West Texas Region Disposal Facility. Groundwater from the Contractor's dewatering operations is expected to be treated, if necessary, by the Contractor to concentration levels meeting the requirements for release to surface waters or release to the City of Lubbock sanitary sewer system as applicable for his operations. 11. Can soils that are potentially contaminated or that have been remediated to less than the regulatory requirements constituting mandatory disposal or remediation be placed back into the trench as backfill? Ans. Yes. However, if the soil has not been remediated to less than 50 ppm TPH and non-detectable levels of BTEX and MTBE, it is desired that the soil be placed back into the trench as near its Page 2 of 4 horizontal location (station) of origin as feasible, within reason. Placement back into the soil's original vertical position is likely not achievablefrom a practical standpoint. 12. What does the West Texas Region Disposal Facility currently charge for petroleum -contaminated soil_ disposal? Ans. $26.25 per ton'with a $15.00 surcharge for each load not properly covered. Also see Addendum No. 1, paragraph 76. 13. What is the selection criteria for ITB #001 -OINK? r Ans. The selection criteria for ITB #001-01NK shall be, "the lowest responsible bidder" in accordance with Chapter 252 of the Local Government Code. 14. Once the low bidder is selected for ITB #001-01NK and ITB #078 -OINK what is the criteria for selection of the award of the contract for the project? Ans. A selection committee consisting of several members of City staff shall conduct a cost benefit analysis and make a recomme_ndationto senior management. Ultimately, the City Council will make the decision based on what they feel is most advantageous for the City of Lubbock. 15. Please provide information that shows what types of contaminants and contamination levels are_ present from station 72+60 to 93+00. The geotechnical data for that area does not indicate any contamination. Ansa See the enclosed."Design Engineer's Interpretation and Opinion". Also see Addendum No. 1, paragraph 43. 16. The majority of line A4 is well below the groundwater table. Page 02111-3 of the specifications list stations 442+00 to 453+00 to have only potential soil contamination. Should the contractor assume water contamination also? Ans. Water contamination is dependent on the draw down for the dewatering operation and duration of that operation. See the enclosed "Design Engineer's Interpretation and Opinion". Also see Addendum No. 1, paragraph 43. _ _ _. 17. How many monitoring wells will be needed to demonstrate the spread of contamination onto City property? Ans.' One'for each`20Olinearfeet of trencti`dewaferng operation, or portion thereof. For example, a ;. single 200 -foot trench length dewatering operation will require two wells, a 300 -foot trench length will require three wells, a 400 -foot trench length three wells, a'500 -foot trench length four wells, etc. 18. Drawing G-13'lists stations 241+00 to 244+00 (Carlisle Motors) and 299+56 to 302+75 (Bolton's#9) as areas where Hydrocarbon resistant pipe is required. These areas are not shown as potentially contaminated per 02111-3 of the specifications? Are these areas contaminated? Ans. See the enclosed revised specification Section 02111 and the enclosed"Design Engineer's Interpretation and Opinion". Also see Addendum No. 1, paragraph 43. 19. The quantities for the pipe in bid items A2 and A3 in the bid form of Contract #001-01NK are diff, erent _ that the quantities for bid items 2 and 3 in the bid form of Contract #078-01NK. Please clarify! Ans. This is corrected below. _ CITY -INITIATED OR ENGINEER -INITIATED ADDENDA 20. Bid Form, Exhibit "A" Page 4. ­" Ans.

Spread stockpiled material to a maximum depth of 18 inches and make at least 3 passes with a disc harrow and at least 3 passes with a road grader to turn material completely over. 2. Make the specified passes to turn material over at least twice per day for 5 consecutive days or until the material contains less than permissible levels of contaminants._ E. If acceptable emission rates are exceeded and level of contamination is below levels prescribed in paragraph 3.6.I, Contractor may choose to dispose of contaminated soil or develop and implement an appropriate emissions control plan, both subject to approval by the Engineer. Such a plan should include provisions to work the soil as described in paragraph 3.6.D, limit emissions to below allowable levels, and obtain required TNRCC permits. F. If acceptable emission rates are exceeded and level of contamination exceeds levels prescribed in paragraph 3.6.I, Contractor may choose to treat contaminated soil by another method or develop and implement an appropriate emissions control plan, both subject to approval by the Engineer. Again, such a plan should include provisions to work the soil as described in paragraph 3.6.13, limit emissions to below allowable levels, and obtain required TNRCC permits. G. Transport contaminated soil in accordance with Department of Transportation and TNRCC rules and regulations. Use a licensed carrier acceptable to the Engineer for such transport. H. Dispose of contaminated soil at a properly licensed facility with prior approval of the Engineer. L Assure that limits of contamination for disposal at the facility are not exceeded. General limits for proper disposal of Class II petroleum contaminated soil at landfills are listed at the end of this Section in Table C, "Contamination Limits for Disposal of Class II Soil". 1. Contact the landfill operator for exact disposal limits and for requirements regarding disposal of other types of contaminated soil. 2. Obtain signed manifests from the receiving facility and provide originals to the Engineer. J. Contaminated soil that exceeds the concentrations listed in I Table C can be taken to the City of Lubbock treatment unit on the northbound frontage road of IH -27 between Municipal Drive and Erskine Avenue., The city will then treat the soil at the city's expense. The Contractor's responsibility for the material ends with the delivery to the city. 3.7 HANDLING WATER A. Install and operate groundwater control systems, as described in Section 02240 - Dewatering, and conduct construction activities in, potentially contaminated areas to minimize the spread of contamination. Design and operate the groundwater control systems such that water from potentially contaminated areas is handled in systems separated and isolated from groundwater control systems outside of the potentially contaminated area. B. Handle, test, treat, and discharge contaminated water to the storm or sanitary sewer in accordance with City of Lubbock, TNRCC, and EPA requirements. 1. Subchapter H of Section 321, 30 TAC describes the requirements of TNRCC for handling, testing and discharging water contaminated with petroleum to the storm sewer. 2. On-site water handling, treatment, and disposal systems, if not already permitted, are subject to the air permitting provisions of paragraph 3.6.C. 3. All such activities shall be under the direction of an Individual licensed by theState of Texas as a Corrective Action Project Manager with 40 hours of Health and Safety Training. 01257198 EXCAVATION, HANDLING AND DISPOSAL 02111 -6 04/01 OF CONTAMINATED MATERIAL -REVISED ITB #001-01/VK, Addendum #4 C. Treat potentially contaminated, impacted, and contaminated water to be discharged to City storm or sanitary sewers in accordance with Table D, or as required to meet other disposal requirements. 1. Provide equipment sized according to standard engineering practices to handle flows anticipated by dewatering operations. *^ 2. Include a standard sized, commercially available oil/water separator as part of the treatment system suitable for intended use for dewatering operation discharges to a storm or sanitary sewer. 3. Where groundwater contamination levels exceed those noted in the Table D, provide additional treatment systems as needed prior to discharge to the sanitary or storm sewers. Any discharge of contaminated groundwater shall be treated with an airstripping or activated carbon unit or other such system.. . 4. Do not discharge treated water into a sewer if the flow is less than one foot below the top of the manhole or would cause an overflow situation. 5. Do not discharge into sanitary sewer without permit from City of Lubbock. ■^^ 6. Recover free product collected in the treatment equipment. 7. Recycle (i.e., for beneficial reuse) or dispose of recovered contaminants in a manner acceptable to the Engineer and the TNRCC. 8. Transport contaminated water and recovered contaminants in accordance with Department of Transportation and TNRCC rules and regulations. Use a licensed carrier acceptable to the _ Engineer for such transport. 9. Obtain signed manifests from the receiving facility and provide originals to the Engineer. 10. Furnish laboratory reports to the Engineer within one week of sample date. D. Obtain approval and/or required permits from the City for discharge directly to a sanitary sewer which discharges to a City -owned wastewater treatment plant prior to commencing such discharge. E. If contamination levels are below levels indicated_ by the NPDES permit for the storm sewer, then obtain a permit from the TNRCC for discharge directly to that storm sewer prior to commencing such discharge. Obtain level limits and other requirements or restrictions from owner/operator of storm sewer. F. Limits for discharge of water contaminated with only petroleum to sewers are given at the end of this Section in Table D, "Petroleum Contaminated Groundwater Discharge Limits". 3.8 DISPOSAL OF MATERIAL NOT CONTAMINATED A. Dispose of excess or unsuitable excavated materials, that are not contaminated, off the job site in ► accordance with Section 01.576 - Waste Material Disposal. 01257198 EXCAVATION, HANDLING AND DISPOSAL 02111 -7 04/01 OF CONTAMINATED MATERIAL - REVISED ITB #001-01/VK, Addendum #4 TABLE A ANALYTICAL TESTS SUSPECTED CONTAMINATION ANALYTICAL TESTS TO BE PERFORMED Gasoline BTEX (if no free product is visible) Benzene TPH Toulene MTBE (water only) Ethyl Benzene Ignitability/flashpoint (if free product is visible) Total Xylenes Lead Oil and Grease Diesel fuel BTEX (if no free product is visible) Jet Fuel TPH Fuel Oils: Nos. 1, 2 and 4 PAH Ignitability/flashpoint (if free product is visible) Oil and Grease Lubricating oils TPH Hydraulic fluids PAH No. 6 fuel oil Oil and Grease Unknown petroleum contamination BTEX Waste oils TPH PAH VOC Total metals (soil only) Oil and Grease Notes: BTEX - benzene, toluene, ethyl benzene, and xylene SVOC - semi -volatile organic compounds TPH -total petroleum hydrocarbons TOX - total organic halides MTBE - methyl tertiary butyl ether PAH - Polycyclic aromatic hydrocarbons VOC - volatile organic compounds TABLE B SOIL CONTAMINATION CRITERIA - PETROLEUM ON'LV".. — CONTAMINANT MAXIMUM CONCENTRATION (mg/kg) TPH 200 Benzene 0.5 Toulene 20 Ethyl Benzene 10 Total Xylenes 70 01257198 EXCAVATION; HANDLING -AND DISPOSAL 021111"=` 8 04/01 OF CONTAMWATEDMATERIAL -'REVI5E`0 Note: TCLP - toxicity characteristic leachate procedure (40 CFR 261, Appendix 11) .., TABLE D PETROLEUM CONTAMINATED GROUNDWATER DISCHARGE, LIMITS, _ .

END OF SECTION 02111 01257198 EXCAVATION, HANDLING AND DISPOSAL 04/01 OF CONTAMINATED MATERIAL - REVISED No Text 6a 0-4 ,., City of Lubbock PURCHASING DEPARTMENT ROOM L04, MUNICIPAL BUILDING 1625 13- STREET LUBBOCK, TEXAS 79401 PH: (806)775-2167 FAX: (806)775-2164 http://purchasing.ci.lubbock.tx.us ADDENDUM #3 ITB 001-01/VK SOUTH CENTRAL LUBBOCK DRAINAGE IMPROVEMENTS Drawing Sheet G13 Permissible Materials MAILED TO VENDOR: April 12, 2001 CLOSE DATE: April 25, 2001`@ 3:00 p:m. (CST) THE FOLLOWING ITEMS TAKE PRECEDENCE OVER SPECIFICATIONS FOR THE ABOVE NAMED INVITATION TO BID (ITB). WHERE ANY ITEM CALLED FOR IN THE ITB DOCUMENTS IS SUPPLEMENTED HERE, THE ORIGINAL REQUIREMENTS, NOT AFFECTED BY THIS ADDENDUM, SHALL REMAIN IN EFFECT. 1. Can pipe types be mixed? Different types of pipe can be used, however a transition structure or manhole must be used connecting RCP to CIPNRCP. On Line A-1 from Station 54+00 to 175+00 CIPNRCP is allowed except for railroad crossings at five locations which can not be open cut. Will a manhole or transition structure be required on either side of every crossing in order to place CIPNRCP? Ans. The abbreviations for the pipe types listed above are shown on drawing Sheet G13. This answer amends and clarifies the answer given in paragraph 15 of Addendum No. 1 and applies wherever a transition occurs or is proposed by the Contractor between pipe types: A. If an inlet or headwall/wingwall structure is indicated on the drawings within 300 feet of a proposed transition between pipe material types that involves CIPNRCP, then the transition ,. will be denied and the same type of pipe material (RCP, CCFRP or CIPNRCP as permissible for that pipe segment as listed on drawing sheet G13) must be placed to the designated inlet or headwall/wingwall structure. Pipe material transitions can occur at inlet structures, if more than one storm sewer line enters the inlet structure. B. A transition between RCP and CCFRP, at other than a manhole location, shall be performed as stated in paragraph 15 of Addendum No. 1 using an RCP -specified joint. C. For a transition between RCP and CIPNRCP, the end of the CIPNRCP shall be smooth and perpendicular to the axis of the pipe. Joint gap between CIPNRCP and other pipe materials shall be minimized, and under no circumstance shall the joint gap exceed two inches. Coat both pipe ends at the transition with a pigmented water -insensitive epoxy bonding agent for bonding plastic concrete to cured concrete. The pigmented epoxy bonding agent shall meet the requirements of ASTM C881, Type V, Grade 3, Class according to temperature of substrate. A non -reinforced concrete collar shall be cast in place, two feet in width centered on the joint and with a thickness equal to 1.5 times the thickest pipe wall joined at that ,,. location, and shall encompass the full circumference of the joint. Once the initial curing has taken place such that forms for the collar can be removed, the entire collar's exterior shall be coated with pigmented curing compound. The interior of the joint shall be filled and smoothed to the interior surface of the pipe with the same polyurethane compound normally used to seal CIPNRCP to water -tight conditions. For pipelines 30 inches in internal diameter and smaller, the polyurethane filling of the joint's interior will not be required. D. - For a transition between RCP and CCFRP, the same procedure as in paragraph "C" ,., immediately above shall apply, except that the CCFRP shall have an external anchor ring around its circumference to anchor the collar against longitudinal movement and also act as a waterstop. Epoxy bonding agent shall not be applied to CCFRP. The external anchor ring shall not be less than one -inch in width nor less than one -inch in height in cross-sectional dimension and shall be of the same material as, and structurally bonded to, the CCFRP. If the anchor ring is taller than one inch and, in the Engineer's sole opinion', is sufficiently tall to materially affect the concrete collar's integrity, then the cast -in-place concrete collar thickness Page 1 of 14 shall be increased to the Engineer's satisfaction and at no additional compensation. The polyurethane joint filler shall not cause detrimental effects to the CCFRP and a manufacturer's statement that the CCFRP materials and the polyurethane joint filler are compatible shall be required. For pipelines 30 inches in internal diameter and smaller, the polyurethane filling of the joint's interior will not be required. E. The completed joint shall meet the requirements for water -tightness as specified for the specific reach of storm sewer pipe. 2. Is direct -jack installation (single pass method) of RCP or CCFRP an acceptable alternative to liner plate installation (two pass method) where liner plate is specified if the direct jack pipe is worthy of design loads without help of the liner plate? Ans. Yes. See paragraph 36, Addendum No. 1. 3. At locations where the liner plate is specified, details read "96 -inch diameter minimum tunnel liner plate if open face or shielded face tunneling is used". Is this statement meant to exclude the use of ribs and lagging or is this statement suggesting that if microtunneling is used, the pipe may be direct jacked? Are steel ribs and lagging allowed as a primary tunnel liner at any locations, including ones where liner plate is detailed? Ans. A. The RCP and CCFRP pipe may be direct -jacked in accordance with specifications without a tunnel liner. Also see Addendum No. 1, paragraph 36, and paragraph 2 of this Addendum No. 3. B. Ribs and lagging maybe used for tunnel lining purposes at any location except where steel casing is indicated on the drawings. Also see Addendum No. 1, paragraph 64 and the remainder of this Addendum No. 3. 4. In regard to paragraph 2, Addendum No. 1, can vertical bench depth be exceeded at other locations as well? With an allowable bench width of 22 feet, a vertical bench depth of 5 feet is restricted. Will the City consider a vertical bench greater than 5 feet for flow lines in excess of 35 feet? Ans. Yes. The maximum bench depth permissible is hereby amended from 5 feet to 10 feet. 5. If the Contractor doesn't need the entire 22 feet of width indicated on the drawings for benching down for equipment reach, can the bench -down width be less? Ans. Yes. 6. The plans show about a one -block length for allowable trench work. Explain how access to homes and businesses is going to work. Isn't it in the specifications that the Contractor will notify property owners? Ans. The City and the Engineer are aware that inconveniences will occur and some residents may not be able to reach their homes or driveways by vehicle for a few days. Yes, the Contractor is to notify property owners in accordance with specification Section 01140, Work Restrictions. Section 01140 also specifies that certain assistance may be required to those handicapped persons whose access is temporarily affected. 7. Is there a list of what streets get what type of paving repair? Ans. Yes, sheet C18 has the different street cross sections and the notes under those cross sections indicate which pavement treatment applies to the various locations of the work. 8. On the bid form Exhibit "A" under Bid Item No. 1 for Mobilization/Demobilization, part of the items listed are for preparation of an "NOI" and an "NOT". What are these items and where is the description of them? Ans. An NOI is a "Notice of Intent" to perform construction activity that will disturb more than a certain amount of surface area, and this form is submitted to the Environmental Protection Agency (EPA) at the address indicated on the forms prior to construction. An "NOT" is a "Notice of Termination". This also must be filed with EPA, Region 6, Dallas, Texas. This informs the EPA that the work covered under the NOI submitted for the specific work is Page 2 of 14 complete and that the disturbed surface has been stabilized with vegetation or pavement. These documents have had to be submitted for the past several years to EPA in conformance with the Code of Federal Regulations. Attached as a part of this addendum are the NOI form (both the plain form and the annotated form), the NOT form, the Region 6 endangered species list for Texas, the sample sign required when the storm water pollution plan is at a location other than theLLwork site or heading, and the Federal Register from the EPA Region 6 web site and for the Contractor's information. The actual documents required at the time of filing the NOI and NOT may be somewhat different as the Owner has no control over the timing and procedures of the federal government making revisions or changes to their documents. 9. Who submits the NOI's? Ans. The Contractor will submit his own NOI's at the appropriate time. The City of Lubbock will submit NOI's on their own behalf. It is anticipated that the Contractor and the City will coordinate the information to be placed on their respective NOI's. �. 10. What is the process to determine whether endangered or threatened species exist at the Project Site? Ans. Endangered Species are addressed in the July 6, 1998 Federal Register, Part II Environmental Protection Agency "Reissuance of NPDES General Permits for Storm Water Discharges From Construction Activities in Region 6; Notice". The steps required for an applicant to assess the potential effects of their storm water discharges and related activities on listed species and their critical habitat are included in the Notice in "Addendum A — Endangered Species, I. Instructions to Applicants, B. Procedures". The assessment is .,, required by the cited regulations to be made prior to an applicant submitting his Notice of Intent (NOI) form. LL A federal listing of "Threatened and Endangered Species" by State and County is available at 6 , http://www.epa.gov/owm/cons pdf/const tx.pdf. This list is currently updated through December 31, 1999. Currently, there is no entry for Lubbock County, Texas, in this listing. The Texas Parks and Wildlife Department maintains a County -by -County listing of rare species. The listing indicates the current federal and state status of listed species of animals and plants, and is updated periodically. Currently, this listing is not available on-line, however the list may be obtained from TPWD, Wildlife Diversity, 3000 IH -35 South, Suite 100, Austin, TX 78704 ((512)912-7011 or (512)912=7058 fax]. Also see the remainder of this addendum for additional information. 11. What happens if an endangered/threatened species enters the project after start of work? Ans. This is dependent on the type of species and the activity of that species, and every scenario can't be accounted for in this addendum. For example, if a listed bird species is just "passing through", then the bird will probably be gone of its own accord within a short time. But, if the listed bird starts nesting in the project site, then that is a different proposition and circumstances will dictate a course of action, if any is necessary. However, it is expected that applicable federal and state law will be followed. 12. Can cement -treated base be used instead of caliche flexible base and/or asphalt -stabilized base? Ans. No. 13. On sheet G3 of the plans, Street and R.O.W. Note 6 states that for excavation in paved areas that the asphalt surfacing shall be salvaged and delivered to the City of Lubbock stockpile location at 84'h Street and Avenue P. Also, it states that the Contractor is not required to perform milling of the material. Rather than performing the above requirement, can the Contractor use an asphalt grinding machine to pulverize the material to one -inch minus material size, blend the asphaltic material with the native materials, and use this blended material in the trench backfill? Ans. No. The asphalt material is to be salvaged and handled as originally specified to the depth indicated in Note 10 of that same drawing number and notes section. Asphalt materials that are in excess of four inches depth below the surface (which would be below the maximum rte•+ Page 3 of 14 salvage depth in Note 10) may be processed and blended with native materials and then used as trench backfill. The Contractor's attention is drawn to the fact that the blending and use of such material may affect the soil material density characteristics, and the development of specific density curves may be necessary for such material. 14. This question is about sheet C20 of the drawings and the trench details for flexible pipe and precast reinforced concrete pipe. Can the Contractor Use a round trench,bottom from the spring line down which would be shaped by using a cast -in-place concrete pipe excavation bucket? It is believed that a round trench bottom will give better support than a flat trench bottom. Ans. The Engineer has some experience with rounded trench bottoms, and has found that certain combinations of rounded trench bottom, backfill materials and backfill construction techniques are inadequate in properly and uniformly supporting prefabricated pipe. Also, unless close tolerances are held during the shaping of the trench to adhere to the complete and uniform bedding of the pipe, then point loads can develop during backfilling operations that can potentially damage the pipe. The details as shown in the drawings conform to, or exceed, the manufacturer's recommendations and recommended practice. The installation requirements were coordinated with the various manufacturers during design of the project. Therefore, rounded trench bottoms for prefabricated pipe will not be allowed to replace the installation details shown. 15. Does the City have provision for an early completion incentive payment? Ans. No. Also see Addendum No. 2, paragraph 4. 16. Is there a required bid bond form to be submitted with the bid? Ans. No. The City does not have a specific bid bond form that the Bidder is required to use. 17. Please clarify the intent for the potholing of existing utilities in areas where surface access is not allowed. Ans. As regards the Burlington Northern Santa Fe (BNSF) Railway Company and South Plains Switching right-of-ways, the BNSF permit granted to the City shall govern. Paragraphs 7 and 8 of that permit state: "Prior to any boring work on or about any portion of the Premises, Licensee shall explore the proposed location for such work with hand tools, to a depth of at least three (3) feet below the surface of the ground to determine whether pipeline(s) or other structures exist below the surface, provided, however, that in lieu of the forgoing, the Licensee shall have the right to use suitable detection equipment or other generally accepted industry practice (e.g., consulting with the Underground Services Association), to determine the existence or location of pipeline(s) and other subsurface structures prior to drilling or excavating with mechanized equipment. Prior to installation, five (5) days advance notice must be given to Licensor's Roadmaster at 500 Main Street, Lubbock, TX 79401, telephone (806) 765-3955." Within that original railroad permit application, the application states that no machine excavation shall take place within 25 feet of a rail, and that the "no surface access" reaches shown on the drawings were also in the permit application. Therefore, only hand excavation will be allowed within the railroad right-of-way. As for the Texas Department of Transportation (TxDOT) right-of-ways and facilities, any potholing for utility locations must first be cleared in writing with TxDOT. The Owner's permits with TxDOT do not allow any excavation within its right-of-way. The Contractor is encouraged to require that the utility locating entity provide vertical information on the utilities that they do locate. For "no surface access areas that are still within the City's indicated right-of-way or within nt existing indicated storm water related easemes that, are controlled by the City, potholing for utilities' exact locations will be allowed at the tunneling or boring access shaft locations, but not within the no access zone. Such potholing shall only be sufficient for location Page 4 of 14 r� confirmation. Street repair may require some cement -stabilized or lean concrete backfill - - below asphalt level depending on the size of the pothole. The smaller potholes normally can not be repaired effectively without some type of treated backfill. Edges of asphalt shall be saw cut and coated with specified tack coat prior to asphalt placement repairs, and the surface hot -mix asphalt course shall match the thickness indicated on drawing Sheet C18 for the street's level of service. 18. Is it possible for the City to award the project to multiple bidders such as Base Bid to one contractor and a Base Bid Option to another contractor? Ans. No. Only one contractor will be awarded a contract regardless of the Base Bid Options - accepted by the Owner. 19. To achieve 95 percent compaction according to ASTM D698, maintaining plus or minus two percent optimum moisture will be critical and costly. What types of soil processing and admixtures has the City used in the past to condition the soil to obtain this compaction specification? Ans. No soil amendments, processing or admixtures have knowingly been used in the vicinity on prior projects to obtain specified moisture content and specified density. The Contractor is not prohibited from processing materials or using admixtures if he deems it suitable for his operations and to meet specifications. However, any admixtures that might interfere with in- place field density tests using a nuclear density gauge must be disclosed to the Owner. 20. Where will the Contractor damage existing sprinkler systems? Ansa The known or suspected areas containing sprinkler systems are stated on the various plan -profile sheets in the drawings. Also see General Instructions to Bidders, paragraph 20 and the Special Provisions, paragraph SP -7. 21. How will the Contractor overlap the joint, or seam, of the filter cloth on Outlet Al when it has to be constructed one-half at a time with sheet piling? Ans. It is not expected that the filter cloth will be able to be overlapped in the center of the channel at Outlet Al because of the center sheet piling common to both halves of the construction sequence. However, 6 to 12 inches of filter cloth material shall be placed against the center cofferdam and on each face of it. This material will probably be damaged upon removal of the cofferdam, but that cannot be avoided. Once the center cofferdam is removed, the rock riprap on either side of it will settle against each other and the installation should then appropriately fulfill its intended design function. 22. What is the intent to keep from damaging the filter cloth when the second half of the shoring is installed? Ans. It is suggested that filter cloth located in the area within the second half of the shoring not be placed until after that shoring is installed. Minor damage to the first-half filter cloth's outer periphery in the main channel, which was placed during the first half of the channel work, is expected while the second half shoring is being constructed. 23. Will the Contractor be required to compact backfill outside of paved areas to 95% density as required in specification Section 02300 and Section 02317? Ans. Yes. 24. Will the Contractor be required to "chip -seal" (same as seal coat) the asphalt street surface after paving is completed? Ans. No, the Contractor is not required to chip seal or seal coat the streets after paving is completed. 25. In specification Section 01500, page 5, will the Contractor be required to furnish a full-time, around- the-clock security guard with every heading or crew on the project? Ans. As stated in the specification cited, a security guard is required 24 hours per day, 7 days per week when the site is unattended: Page 5 of 14 A. Interpretation: If the site is unattended, as an example, over a three-day holiday weekend, then a security guard is required 24 hours per day for each of those three days because the site is unattended by the workmen. B. Interpretation: If, as another example, during the work -week the site has workmen in attendance for 8 hours per day, then the security guard is only required for the remaining 16 hours of each of those days. It is expected that the superintendent and workmen will act as site security to prevent unauthorized entry while they are performing their labors during the work -day. C. Interpretation: If tunneling operations are allowed to proceed seven days per week, 24 hours per day (see Addendum No. 1, paragraph 38), the site is expected to be occupied by workmen and secured by them. Thus a security guard will not be required while workmen are on site and at least one worker is at the surface where he can make observations while performing his other duties and enforce unauthorized entry. D. Since security fences with lockable gates are also called for in the same specification at each work site or heading, one roving security guard will be allowed to cover multiple work sites within a three-mile contiguous length of the project, as measured along the stationing of the storm sewer, if the security chain-link fence at each work site or heading is at least seven feet in height, has less than 2-1/2 inches clearance between the fence bottom and ground surface, and the fence's gates are locked. Such roving security guard must view each site or heading within that reach at least once per hour while on duty. If the security guard can not view each site or heading within that reach at least once per hour, then the guard's area of coverage must be reduced to meet the time restriction. E. If the fence is less than seven feet in height, or has a bottom clearance greater than 2-1/2 inches from the ground surface, then a security guard must be able to view each specific work site or specific heading at least every 20 -minute interval when on duty. This will have to be judged on a case-by-case basis and is dependent on the travel time between sites or headings at any stage of the project and the line -of -sight between sites or headings. In no case shall a single security guard's coverage exceed the three-mile contiguous length noted in item D immediately above. F. Where steel plates are used to temporarily cover trenches in accordance with paragraph 25 of Addendum No. 1, a fence will not be required to enclose the steel plated trench length so long as the steel plates are butted flush with one another to form a continuous cover over the excavation. In that case, a single security guard may be used under the provisions of item D immediately above for a contiguous storm sewer stationing length and site viewing time interval. G. Both security fence and security guard will not be required from Station 0+00 to approximate Station 19+20 (east fence at Farmers Coop Compress) provided that the City's property boundary fence is intact and the gates are locked. (Note: The storm sewer crossing at Guava Avenue within this station range is not planned for any construction, other than maybe temporary potholing by the Contractor for utility locations, within the right-of-way for Guava Avenue). H. All other locations in the project will require security as specified in Section 01500 and as modified by this addendum. 26. What is the status of the Corps of Engineers 404 permits? Ans. It has been over 60 days since the Owner submitted the request, and no official response has yet been received. As of this time of this addendum, no changes are expected as a result of the Corps of Engineers' review. The Bidder should also see Addendum No. 1, paragraph 46. 27. In the drawings, the pipe alignment is shown down the center of many narrow streets, Can the alignment be moved to one side of the street, depending on the segment and location in the project? Ans. Where, in the opinion of the Engineer, it appears to be feasible after considering existing utilities, traffic, driveway closures, rate of construction, and other items that may need Page 6 of 14 consideration, alignment adjustments can be made with the approval of the Engineer. When such alignment adjustments are approved, the Contractor shall provide the coordinates and elevations necessary for accurate development of record drawings by the Engineer or Owner. This shall also include curve data where such pipeline curves are adjusted from those indicated on the plans to include the typical curve information such as that shown on the Horizontal Alignment Data Sheets of the drawings. Such alignmentchanges will only be considered on a case-by-case basis. 28. The plans and specifications show about a one -block length allowable for trench work. How is the access to homes and businesses going to work? Ans. The Owner and Engineer know that unavoidable inconveniences are going to arise. The specifications in Section 01140 address the identifiable special cases. 29. Isn't it in the specifications that the Contractor will notify the property owners? ' Ans. Yes, in specification Section 01140, page 4, paragraph 1.9. 30. Will the City assist in notifications to outside entities? Ans. Yes. The Owner will assist with the dissemination of information about the project through a planned newsletter and press releases. The Contractor's responsibilities in Section 01140 of the specifications remains unchanged. 31. Our office is located in another state and I am not sure if the Workman's Compensation Experience Rating is the same as that for Texas. Could this be clarified? Ans. This question was addressed in Addendum No. 1 in paragraphs 50 and 69. A method is given in those paragraphs for Workman's Compensation Experience Rating for those states who do not participate in the National Council on Compensation Insurance Worker's` r " Compensation Experience Rating System. 32. Under specification Section 01500, page 4, paragraph 3.3.D. How many project identification signs must the Contractor supply for the project? Ans. A. One sign shall be located at each of the Contractor's primary stockpile sites, excluding soil material stockpiles. A primary stockpile site does not include where pipe might be strung on the surface along the storm sewer route ahead of excavation activity. Also, a sign is not required at the salvaged asphalt stockpile site owned by the City at 84t" and Avenue P. B. One sign shall be located at the Contractor's common -use field office, unless the field office is within a permanent structure leased or owned by the Contractor (for example, office space leased in an office building or an office park). C. One sign shall be located at each work site or heading, except that project identification signs are not required at a work site or heading that is less than 1,320 feet (approximately two city blocks along a block's long axis, based on Lubbock's standard block dimensions) of another work site or heading that has a sign, excluding lake areas. D. One sign shall be located at each lake area where construction activity is taking place within that lake area. E. Signs may be relocated and re -used as work progresses, and work site and heading locations change. F. Signs at work sites and headings may be attached to the specified security fence or otherwise firmly secured and visible in lieu of post supports. G. The Contractor's sequence of operations, spacing of operations, number of sites simultaneously occupied, and other factors under the Contractor's control will determine the number of project identification signs that will be needed in accordance with this addendum. H. This does not relieve the Contractor of storm water pollution prevention signage as required by the EPA storm water regulations for construction activities. Page 7 of 14 33. There is not enough room along most of the project to stockpile the excavated material alongside the route. How is the Contractor supposed to handle all of that soil? Ans. The means and methods for handling the excavated materials, except as may be specified or indicated in the documents, are the domain of the Contractor. For informational purposes only, the Engineer has seen excavated materials in prior projects and under similar circumstances that were loaded directly into trucks from an excavating trackhoe and no "adjacent -to -the -trench stockpiling" was done. It is the Contractor's responsibility to determine how to handle the excavated soil volumes according to his operations. 34. Request that you reconsider the tunnel liner requirements in specification Section 02425, page 3, paragraph 1.5.E, and in Addendum No. 1, paragraph 64 in order to promote more competition in supplying tunnel liner plates and rib and lagging tunnel systems. This is not a request to compromise safety or standard of care, but to re -consider the function and functional duration of the tunnel liner systems for the project so that perhaps different systems meeting the functional objectives might bid on the work. Ans. See the remainder of this Addendum No. 3. 35. Why do the plans call out trenchless crossings from Station 288+25 to Station 311+60 (apparently to avoid existing utility conflicts) while calling out zero trenchless crossings from Station 313+00 to Station 335+00 when the exposure to existing utility conflicts seems to be relatively equal in these two reaches of the proposed storm sewer system. Ans. This question is answered in two parts. A. For trenchless crossings between Station 288+25 to Station 311+60 (at other than 50th Street, a major thoroughfare). During the design of this project, while coordinating with Southwestern Public Service Company and Lubbock Power and Light, the Engineer was informed that the overhead circuits for the neighborhoods in that station range could only be supplied from one direction. In anticipation of the size of open cut excavation equipment, it was decided that the overhead lines would have to be temporarily removed to accommodate excavation equipment maneuvers. The power companies could not temporarily remove those lines because another circuit was not available to supply power to those neighborhoods. Thus, it was decided to require trenchless methods at those specific utility crossings to avoid the potential for equipment interference with the neighborhoods' electrical power supply. B. Zero trenchless crossings from Station 313+00 to Station 335+00. Within this reach of the project, the power companies informed the Engineer that they have more than one circuit with which to supply the neighborhoods. Therefore, the matter is left open to the Contractor as to his installation method and efficiency in his operations. The installation method could be trenchless, it could be open cut with the power lines temporarily taken out of the way, or it could be open cut with the Contractor's forces electing to leave the power lines in place. It is up to the Contractor, if he elects to have the power lines temporarily taken out of service and temporarily removed, to coordinate that expectation with the particular power company. Any charges incurred by the Contractor from the power company will be expected to be included in the bid price. 36. Some of the soil borings in the geotechnical reports by Terra Engineers, Inc. stop above the top of the tunnel and that only a few borings were taken along the tunnel sections of the project. The assumption that we are making, without incurring bid expense on a project that we may not be awarded, is that the Geotechnical Reports accurately depict the ground conditions that we are likely to encounter. In my opinion, this leaves the City open for a Differing Site Conditions claim should this not be the case. We request that the City furnish all the potential bidders on this project with sufficient full depth soil borings along with proper engineering reports on the rocks and soils likely to be encountered. Page 6 of 14 n -- Ans. The City will not be conducting nor furnishing any further geotechnical information. The Special Provisions in paragraph SP -6 of the specifications state the purposes and limitations for furnishing the Terra Engineers, Inc. reports to potential bidders. 37. The specifications say that the Contractor is to identify potential endangered species. How? Ans. The City and the Engineeer are relying upon U.S. Fish and Wildlife listings and Texas Parks and Wildlife listings for Lubbock County. 38. Request that the standard trench and benched trench details for precast reinforce concrete pipe shown on sheet C20 of the drawings be modified to allow pea gravel backfill instead of cement stabilized backfill. Ans. No adjustment to the precast reinforced concrete pipe trench details on drawing sheet C20 will be made. 39. In our conversation with the flexible pipe manufacturers, we have discovered that they assume that the "pea gravel' bedding is a rigid support for their pipe and it is not! Should the specification be written for a bedding that is well graded and hand compacted road gravel? Ans. There. is no pea gravel bedding allowed on this project. All of the trench details on sheets C20 and C21 show a sand bedding where a bedding is required. 40. Are you using the ASTM standard for field joint tests? Ans. The field joint tests are covered in specification Section 02533. 41. 1 saw in the specifications where it shows individual joint testing is permissible for pipes that are 48 inches and larger in diameter. Can individual joint testing be performed down to 24 inches in diameter? Ans. Yes, provided that, in the opinion of the Engineer, reliable procedures are adhered to and reliable results can be obtained. Otherwise, sections of pipe must be tested in accordance with specification Section 02533. 42. How long does the bidder's bid have to be good before the City awards a contract? Ans. Sixty calendar days. The following sentence in the Bid Submittal form is changed to read: "The Bidder agrees that this bid shall be good and may not be withdrawn for a period of six - five 65 calendar days after the scheduled closing time for receiving bids." This should allow more than enough time for the City to evaluate bids and responsible bidders. 43. Can we do test holes in the parks? Ans. Yes. Stay on City of Lubbock property, coordinate with the Parks Department and leave the test hole sites clean. 44. What about test holes on the Farmers Coop Compress property? Ans. The City has a map of the site and contact information. 45. What about test holes in the paved areas of the streets? Ans. Test holes will need to be behind the curb, yet still in City right-of-way. No test holes within pavement. 46. The City of Lubbock web site shows an estimated cost of $36 million. This is greater than the $30.6 million quoted earlier on the Lubbock website. Why the difference? Ans. The $36 million referred to includes design engineering, geotechnical engineering, surveying, aerial photography, and some other costs associated with the project in addition to estimated construction. 47. Is there any value associated with doing more tunneling? For example, if a bidder who was doing more tunneling of the project came in higher than another bidder who was going to open cut as much -- Page 9 of 14 as possible of the project, is there any consideration of awarding the contract to the higher bidder who would do more tunneling and less surface disruption? Ans. No. There's no provision for that type of evaluation or award in the contract documents. 48. What is the Contractor supposed to do with excess materials generated from the work? Ans. See specification Section 01576, Addendum No. 1, paragraph 23 and Addendum No. 2, paragraphs 1 and 2. 49. Which areas are to be re -seeded and which areas are to be re -sod? Ans. The park areas as defined in the specifications are to be re -sod. Range areas may be re- seeded or re -sod at the Contractor's option. 50. What is the seeding rate for areas to be re -seeded? Ans. See specification Section 02920, paragraph 3.43, page 5. The seeding rate is specified as 10 pounds of pure live seed per acre. CITY -INITIATED OR ENGINEER -INITIATED ADDENDA 51. Addition to Special Provisions On page SP -7 of the Special Provisions, add the following new paragraph: "SP -11. In the General Conditions of the Agreement, page 3, paragraph 18, the provisions regarding the character of workmen shall also include persons of female gender wherever the words "man" or "men" is used. The provisions for the character of the workmen shall be construed to include the Contractor's superintendent or superintendents, and Contractor's subcontracted work forces and subcontractor superintendents." 52. Revision to specification Section 01356, page 2, paragraph 1.2.K Replace paragraphs 1.2.K.1 and 1.2.K.2 with the following paragraphs: 1. The U.S. Fish and Wildlife Service lists the following species as threatened or endangered for Lubbock County, Texas in their list updated through December 31, 1999: a. None Federally -listed for Lubbock County, Texas. 2.

Use anchor bolts equal to Hilti HVA System or Hilti Kwik Bolt II System. Total anchor bolt length dependent on frame thickness and number of grade rings. Top nuts, after tightening, shall leave at least three full threads of the bolt showing above the nut. 54. Revision to specification Section 02425, page 3, paragraph 1.5.E, and to Addendum No. 1, paragraph 64. In response to questions regarding the temporary nature of tunnel liners, paragraph 1.5.E on page 3 of specification Section 02425, and paragraph 64 of Addendum No. 1 are hereby deleted. The affected language of both Section 02425 and Addendum No. 1 shall be replaced by the following: "Liner design shall conform to AASHTO "Design Specifications for Tunnel Liner Plate", Section 16. Because of the temporary nature of the tunnel liner and the various liner methods and materials available, such liner design and selection shall be performed by the Contractor or the primary liner "^ supplier. The design shall be sealed by a professional engineer and submitted to the Engineer in accordance with paragraph 1.4.6.2 of this specification.

Benched Trench Detail, Flexibel Pipe (CSB Option), bottom left of sheet — this detail shows a 12 - inch minimum depth of cement stabilized backfill above the top of the pipe. Change the 12 -inch minimum to an 8 -inch minimum depth above the top of the pipe. 63. Clarification to Plan Sheets GR1 Through GR21 Additional clarification is contained in Addendum No. 1, paragraph 35. As regards the sheet pile cofferdams shown on Sheets GR1 through GR21, the intent is to require the Contractor to use cofferdam materials that do not introduce fill material into the indicated areas. Therefore earthen levees or dikes, closed cell earth -filled cofferdams and other such types of cofferdams that introduce r.- what could be classified as fill will not be allowed, however temporary it might be. However, this does not preclude the Contractor from proposing for use proprietary cofferdam systems or H-pile/sheeting Page 13 of 14 rpm types of systems provided that the environmental impact is no greater than what can be expected — from a sheet pile system. 64. Addendum No. 1, paragraph 49 In Addendum No. 1 for the ITB #001-01NK, Drawing Sheet G13 Permissible Materials, wherever the — phrase "Project Options" is used, it shall also be interpreted to mean "Base Bid Options". 65.

Facility Owner/Operator (Applicant) Information Provide the legal name, mailing address, and telephone number of the person, firm, public organization, or any other entity that meet either of the following two criteria: (1) they have operational control over construction plans and specifications, including the ability to make modifications to those plans and specifications; or (2) they have the day-to-day operational control of those activities at the project necessary to ensure compliance with SWPPP requirements or other permit conditions. Each person that meets either of these criteria must file this form. Do not use a colloquial name. Correspon- dence for the permit will be sent to this address. Enter the appropriate letter to indicate the legal status of the owner/operator of the project: F = Federal; S = State; M = Public (other than federal or state); P = Private. Section II. Project/Site Information Enter the official or legal name and complete street address, including city, county, state, zip code, and phone number of the project or site. If it lacks a street address, indicate with a general statement the location of the site (e.g., Intersection of State Highways 61 and 34). Complete site information must be provided for permit coverage to be granted. The applicant must also provide the latitude and longitude of the facility in degrees, minutes, and seconds to the nearest 15 seconds. The latitude and longitude of your facility can be located on USGS quadrangle maps. Quadrangle maps can be obtained by calling 1-800 USA MAPS. Longitude and latitude may also be obtained at the Census Bureau Internet site: hftp://www.census.gov/cgi-bin/gazetteer. Latitude and longitude for a facility in decimal form must be converted to degrees, minutes and seconds for proper entry on the NOI form. To convert decimal latitude or longitude to degrees, minutes, and seconds, follow the steps in the following example. Convert decimal latitude 45.1234567 to degrees, minutes, and seconds 1) The numbers to the left of the decimal point are degrees. 2) To obtain minutes, multiply the first four numbers to the right of the decimal point by 0.006. 1234 x.006 = 7.404. 3) The numbers to the left of the decimal point in the result obtained in step 2 are the minutes: 7'. 4) To obtain seconds, multiply the remaining three numbers to the right of the decimal from the result in step 2 by 0.06: 404 x 0.06 = 24.24. Since the numbers to the right of the decimal point are not used, the result is 24". 5) The conversion for 45.1234 = 45° 7' 24". Indicate whether the project is on Indian Country Lands. Indicate if the Storm Water Pollution Prevention Plan (SWPPP) has been developed. Refer to Part IV of the general permit for information on SWPPPs. To be eligible for coverage, a SWPPP must have been prepared. Optional: Provide the address and phone number where the SWPPP can be viewed if different from addresses previously given. Check appropriate box. Enter the name of the closest water body which receives the project's construction storm water discharge. Enter the estimated construction start and completion dates using four digits for the year (i.e. 05/27/1998). Enter the estimated area to be disturbed including but not limited to: grubbing, excavation, grading, and utilities and infrastructure installation. Indicate to the nearest acre; if less than 1 acre, enter 1." Note: 1 acre = 43,560 sq. ft. Indicate your best estimate of the likelihood of storm water discharges from the project. EPA recognizes that actual discharges may differ from this estimate due to unforeseen or chance circumstances. Indicate if there are any listed endangered or threatened species, or designated critical habitat in the project area. Indicate which Part of the permit that the applicant is eligible with regard to protection of endangered or threatened species, or designated critical habitat. Section III.

SUPPLEMENTARY INFORMATION: Contents I. Introduction II. Answers to Common Questions III. Section 401 Certification and Coastal Zone Management Act - associated with construction activity. used in this permit, "storm water associated with construction activity" means construction activity disturbing at least five acres, or construction activity disturbing less than five acres which is part of a larger common plan of development or sale with the potential to disturb cumulatively five or more acres (See 40 CFR 122.26(b) (14) (x)). These permits replace the previous Baseline Construction General Permits which were issued for a five-year term in September 1992. The most significant changes from the 1992 permits are 00, New conditions to protect listed endangered and threatened species and critical habitats; 10 -Expanded coverage to construction sites under five acres of disturbed land which are not part of a larger common plan of development or sale when an operator has been designated by the Director to obtain coverage. 0-A requirement to post at the construction site the confirmation of permit coverage (the permit number or copy of the Notice of Intent (NOI) if arm permit number has not yet been assigned) including a brief description of the project; 00 -Storm water pollution prevention plan performance objectives have been added. These general permits for storm water discharges associated with construction activity was proposed on June 2, 1997 (62 FR 29786), and are hereby issued for the following areas in Region 6: The States of New Mexico and Texas; Indian Country lands in Louisiana, Oklahoma, Texas and New Mexico (except Navajo Reservation Lands and Ute Mountain Reservation Lands); and oil and gas construction in the State of Oklahoma. II. Answers to Common Questions In this section, EPA provides answers to some of the more common questions on the construction storm water permitting program. These answers are fairly broad and may not take into account all scenarios possible at construction sites. More details on these issues are provided at 63 FR 7858 How do I Know ifl Need a Permit? You need a storm water permit if you can be considered an "operator" of the construction activity that would result in the "discharge of storm water As associated with construction activity." You must become a permittee if you meet either of the following two criteria: ► You have operational control of construction project plans and specifications, including the ability to make modifications to those plans and specifications; or ► You have day-to-day operational control of those activities at a project which are necessary to ensure compliance with a storm water pollution prevention plan (SWPPP) for the site or other permit conditions (e.g., you are authorized to direct workers at a site to carry out activities required by the SWPPP or comply with other permit conditions). There maybe more than one party at a site performing the tasks relating to "operational control" as defined above. Depending on the site and the relationship between the parties (e.g., owner, developer), there can either be a single party acting as site operator and consequently be responsible for obtaining permit coverage, or there can be two or more operators with all needing permit coverage. The following are three general operator scenarios (variations on any of the three are possible as the number of "owners" and contractors increases): ► Owner as Sole Permittee. The property owner designs the structures for the site, develops and implements the SWPPP, and serves as general contractor (or has an on-site representative with full authority to direct day-to-day operations). He may be the only party that needs a permit, in which case everyone else on the site may be considered subcontractors and not need permit coverage. ► Contractor as Sole Permittee. The property owner hires a construction company to design the project, prepare the SWPPP, and supervise implementation of the plan and compliance with the permit (e.g., a "turnkey" project). Here, the contractor would be the only party needing a permit. It is under this scenario that an individual having a personal residence built for his own use (e.g., not those to be sold for profit or used as rental property) would not be considered an Federal Register / Vol. 63, No. 128/Monday, July 6, 1998/Notices 36491 operator. EPA believes that the general contractor, being a professional in the building industry, should be the entity rather than the individual who is better equipped to meet the requirements of both applying for permit coverage and developing and properly implementing a SWPPP. However, individuals would meet the definition of "operator" and require permit coverage in instances where they perform general contracting duties for construction of their personal residences. No -Owner and Contractor as Co - Permittees. The owner retains control over any changes to site plans, SWPPPs or storm water conveyance or control designs; but the contractor is responsible for overseeing actual earth disturbing activities and daily implementation of SWPPP and other permit conditions. In this case, both parties may need coverage. However, you are probably not an operator and subsequently do not need permit coverage if. 0 -You are a subcontractor hired by, and under the supervision of, the owner or a general contractor (i.e., if the contractor directs your activities on-site you probably are not an operator); or D-youractivities on site result in earth disturbance and you are not legally a subcontractor, but a SWPPP specifically identifies someone other than you (or your subcontractor) as the party having operational control to address the impacts your activities may have on storm water quality (i.e., another operator has assumed responsibility for the impacts of your construction activities). This particular provision will apply to most utility service line installations. For further information concerning whether utility service line installations meet the definition of operator and require permit coverage, see the discussion under "Installation of Utility Service Lines" in Section VIII, Summary Response to Public Comments of the Fact Sheet. In addition, for purposes of this permit and determining who is an operator, "owner" refers to the party that owns the structure being built. Ownership of the land where construction is occurring does not necessarily imply the property owner is an operator (e.g., a landowner whose property is being disturbed by construction of a gas pipeline). Likewise, if the erection of a structure has been contracted for, but possession of the title or lease to the land or structure is not to occur until after construction, the would-be owner may not be considered an operator (e.g., having a house built by a residential homebuilder). My Project Will Disturb Less Than Five Acres, but it May Be Part of a "Larger Common Plan of Development or Sale." How Can I Tell and What Must I do? If your smaller project is part of a larger common plan of development or sale that collectively will disturb five or more acres (e.g., you are building on six half -acre residential lots in a 10 -acre development or are putting in a parking lot in a large retail center) you need permit coverage. The "plan" in a common plan of development or sale is broadly defined as any announcement or piece of documentation (including a sign, public notice or hearing, sales pitch, advertisement, drawing, permit application, zoning request, computer design, etc.) or physical demarcation (including boundary signs, lot stakes, surveyor markings, etc.) indicating construction activities may occur on a specific plot. You must still meet the definition of operator in order to be required to get permit coverage, regardless of the acreage you personally disturb. As a subcontractor, it is unlikely you would need a permit. For some situations where less than five acres of the original common plan of development remain undeveloped, a permit may not be needed for the construction projects "filling in" the last parts of the common plan of development. A case in which a permit would not be needed is where several empty lots totaling less than five acres remain after the rest of the project had been completed, providing stabilization had also been completed for the entire project. However, if the total area of all the undeveloped lots in the original common plan of development was more than five acres, a permit would be needed. When Can You Consider Future Construction on a Property To Be Part of Separate Plan of Development or Sale? In many cases, a common plan of development or sale consists of many small construction projects that collectively add up to five (5) or more acres of total disturbed land. For example, an original common plan of development for a residential subdivision might layout the streets, house lots, and areas for parks, schools and commercial development that the developer plans to build or sell to others for development. All these areas would remain part of the common plan of development or sale until the intended construction occurs. After this initial plan is completed for a particular parcel, any subsequent development or redevelopment of that parcel would be regarded as a new plan of development, and would then be subject to the five - acre cutoff for storm water permitting. What Must I do to Satisfy The Permit Eligibility Requirements Related to Endangered Species? In order to be eligible for this permit, you must follow the procedures and examples found in Addendum A for the protection of endangered species. You cannot submit your NOI until you are able to certify your eligibility for the permit. Enough lead time should be built into your project schedule to accomplish these procedures. If another operator has certified eligibility for the project (or at least the portion of the project you will be working on) in his NOI, you will usually be able to rely on his certification of project eligibility and not have to repeat the process. EPA created this "coat tail" eligibility option for protection of endangered species to allow the site developer/owner to obtain up -front "clearance" for a project, thereby avoiding duplication of effort by his contractors and unnecessary delays in construction. What Does the Permit Require Regarding Historic Preservation? Today's permit does not currently impose requirements related to historic preservation, though EPA may modify the permit at a later date after further discussions with the Advisory Council on Historic Preservation. Therefore, under today's permit, EPA will conduct consultations as it did under the pre existing Baseline Construction General Permit on a case-by-case basis as needed. Removal of the proposed permit provisions related to historic preservation in no way relieves applicants and permittees of their obligations to comply with applicable State, Tribal or local laws for the preservation of historic properties. EPA reminds permittees that according to section I I0(k) of the National Historic Preservation Act (NHPA), an intentional action to significantly adversely affect historic resources with intent to avoid Federal historic preservation requirements may jeopardize future permit coverage for such a permittee. How Many Notices of Intent (NOIs) Must I Submit? Where and When Are They Sent? You only need to submit one NOI to cover all activities on any one common plan of development or sale. The site map you develop for the storm water pollution prevention plan identifies which parts of the overall project are 0 36492 Federal Register / Vol. 63, No. 128/Monday, July 6, 1998 / Notices under your control.

This prohibition applies to all entities and includes EPA, permit applicants, permittees and the public at large. Second, section 7(a) (2) of the ESA requires that Federal agencies consult with the Fish and Wildlife Service (FWS) or the National Marine Fisheries Service (NMFS) ("the Services") to insure that any action authorized, funded or carred out by them (also known as "agency actions") are not likely to jeopardize the continued existence of any listed species or result in the destruction or adverse modification of critical habitat. Jeopardizing the continued existence of a listed species means to engage in an action that reasonably would be expected, directly or indirectly, to reduce appreciably the likelihood of both the survival and recovery of a listed species in the wild by reducing the reproduction, numbers or distribution of that species (See 40 CFR 402.02). The ESA section 7 implementing regulations at 50 CFR 402 apply this consultation requirement to any action authorized by a Federal agency that may affect listed species or critical habitat, including permits. This effect, among other things, can be beneficial, detrimental, direct and indirect. The issuance of the CGP by EPA is thus subject to the ESA section 7(a)(2) consultation requirements. Finally, ESA section 7(a)(1) directs Federal agencies to use their authority to further the purposes of the ESA by carrying out programs for the conservation of listed species, and section 7(a)(4) directs Federal agencies to confer with the Services on Agency actions likely to jeopardize the existence of species proposed but not yet finally listed or result in the adverse modification of critical habitat proposed to be designated. The ESA regulations provide for two types of consultation: formal and informal. Informal consultation is an optional process that includes discussions, correspondence, etc. between the Services and a Federal agency or a designated non -Federal representative (NFR) to determine whether a Federal action is likely to have an adverse effect on listed species or critical habitat. During informal consultation the Services may suggest modifications to the action that a Federal agency, permit applicant or non -Federal representative could implement to avoid likely adverse effects to listed species or critical habitat. If adverse effects are likely and those effects cannot be addressed through informal consultation, then formal consultation generally occurs. Also of relevance for the CGP are ESA section 10 incidental taking permits. Section 10 of the ESA allows persons, including non -Federal entities to incidentally take listed animal species,. where otherwise prohibited, through the issuance of a permit after development of a habitat conservation plan (HCP). These procedures were developed to allow non -Federal entities such as developers to, among other things, alter habitat without incurring takings liability where take is minimized to the extent practicable. B. Conditions in the June 2, 1997 Proposed Permit To Protect Species and Critical Habitat The CGP was proposed with a number of conditions to ensure that storm water discharges and best management practices (BMPs) to control storm water runoff were protective of listed species or critical habitat. Specifically, coverage under the proposed CGP would be granted only under the following circumstances: 1. An applicant's storm water discharges or BMPs to control storm water runoff were not likely to adversely affect listed species (identified in Addendum A of the permit) or critical habitat: or 2. The applicant's activity was previously authorized under § 7 or § 10 of the Endangered Species Act (ESA) and that authorization addressed storm water discharges and BMPs to control storm water runoff; or 3. The applicant's activity was considered as part of a larger, more comprehensive assessment of impacts on endangered and threatened species under § 7 or § 10 of the ESA which accounted for storm water discharges and BMPs to control storm water runoff; or 4. Consultation under § 7 of the ESA was conducted for the applicant's activity which resulted in either a no jeopardy opinion or a written concurrence on a finding of no likelihood of adverse effects; or 5. The applicant's activity was considered as part of a larger, more comprehensive site-specific assessment of impacts on endangered and threatened species by the owner or other operator of the site and that permittee certified eligibility under items 1., 2., 3. or 4. above. The proposal required that applicants assess the impacts of their "storm water discharges" and "BMPs to control storm water runoff' on listed species and critical habitat that are located "in proximity" to the those discharges and BMPs when developing Storm Water Pollution Prevention Plans (SWPPPs) as part of the application process. The proposed CGP also required applicants to include measures in SWPPPs to protect listed species and critical habitat. "In proximity" was defined in Addendum A to include species: ► Located in the path or immediate area through which or over which contaminated point source storm water flows from construction activities to the point of discharge into the receiving water; ► Located in the immediate vicinity of, or nearby, the point of discharge into receiving waters; or ► Located in the area of a site where storm water BMPs are planned or are to be constructed. EPA also solicited comment on whether the area or scope of impacts to be considered by applicants should be broadened to encompass listed species found on the entire construction site and not just those species found "in proximity" as currently defined in Addendum A. Failure by permittees to abide by measures in their SWPPPs to protect species and critical habitat would invalidate permit coverage. Attached to the proposed permits were instructions (Addendum A) to assist permit applicants in making this inquiry. The proposal indicated that a county -by - county species list would be included in Addendum A of the final permit to assist applicants in determining if listed species might be "in proximity" to storm water discharges and BMPs. EPA did not provide a draft species list in proposed Addendum A. Instead, EPA referred commenters to a similar species list that was used for an earlier EPA - issued storm water permit, the Multisector Storm Water General Permit, that was issued on September 29, 1995 (See 62 FR 29792, note 12, June 2, 1997). 36494 Federal Register / Vol. 63; No. 128/Monday, July 6, 1998 / Notices C.

Such conditions must be incorporated in the applicant's SWPPP. The CGP does not authorize any prohibited take (as defined under section 3 of the ESA and 50 CFR 17.3) of endangered or threatened species unless such takes are authorized under sections 7 or 10 of the ESA. The CGP does not authorize any storm water discharges or storm water discharge - related activities that are likely to jeopardize the continued existence of any species that are listed or proposed to be listed as endangered or threatened under the ESA or result in the adverse modification or destruction of habitat that is designated or proposed to be designated as critical under the ESA. It is EPA's intention to provide permit applicants with the greatest possible flexibility in meeting permit requirements for protecting listed species and critical habitat. Thus, EPA is allowing applicants to use either section 7 or section 10 ESA mechanisms to address situations where adverse effects are likely (See Part I.B.3.e.(2) (b) and (c)). Also, to give applicants additional flexibility in meeting the Part I.B.3.e. eligibility requirements and with the timing of informal consultations, the permit automatically designates CGP applicants as non -Federal representatives for the purpose of carrying out informal consultation. However, EPA notes that meeting ESA requirements raises difficult. implementation issues on how to best ensure that the permits are protective of listed species and critical habitats without unduly burdening permit applicants, permittees, and State, local, and Federal governmental entities. Thus, EPA intends in the future to review those permit conditions and procedures that relate to the ESA and the protection of historic resources to see how well that goal has been achieved and may revise the permits if necessary to better achieve that goal. V. Historic Property Protection A. Background The National Historic Preservation Act of 1966, as amended, (NHPA) establishes a national historic preservation program for the identification and protection of historic properties and resources. Under the NHPA, identification of historic properties is coordinated by the State Historic Preservation Officers (SHPOs), Tribal Historic Preservation Officers (THPOs) or other Tribal Representatives (in the absence of a THPO). Section 106 of the NHPA requires Federal agencies to take into account the effects of their actions on historic properties that are listed or eligible for listing on the National Register of Historic Places and to seek comments from the Advisory Council on Historic Preservation (ACNP). The permit was proposed with a number of conditions pertaining to the consideration of historic properties. EPA has decided to not include those conditions because the ACHP and the National Conference of State Historic Preservation Officers (NCSHPO) have requested that EPA not include such conditions in the final permit at this time. The ACHP and the NCSHPO have recommended that EPA issue the permit but recommend that EPA continue working with them and Tribes regarding the possible development of a more comprehensive and efficient approach to ensure that effects to historic properties are given appropriate consideration while ensuring undue burdens are not imposed on applicants and regulatory authorities. EPA plans to continue working with the ACNP, NCSHPO and Tribes on this effort and may modify the permit to incorporate procedures regarding the protection of historic resources at a later date. B. Future CGP Conditions To Protect or Consider Effects to Historic Properties In response to comments received on the permit proposal and because the Agency is still discussing historic preservation with the Advisory Council on Historic Preservation (ACNP), the final permit reserves permit requirements related to historic preservation. Today's final permit does not include the eligibility restrictions and evaluation requirements from the proposed permit. After future discussions with the ACNP, EPA may modify the permit to reflect those discussions. VI. Regulatory Review (Executive Order 12866) Under Executive Order 12866, (58 FR 51735 [October 4, 1993]) the Agency must determine whether the regulatory action is "significant" and therefore subject to OMB review and the requirements of the Executive Order. The Order defines "significant regulatory action" as one that is likely to result in a rule that may have an annual effect on the economy of $100 million or more or adversely affect in a material way the economy, a sector of the economy, productivity, competition, jobs, the environment, public health or safety, or State, local or Tribal governments or communities; create a serious inconsistency or otherwise interfere with an action taken or planned by another agency; materially alter the budgetary impact of entitlements, grants, user fees, or loan programs or the rights and obligations of recipients thereof; or raise novel legal or policy issues arising out of legal mandates, the President's priorities, or the principles set forth in the Executive Order. It has been determined that this re -issued general permit is not a "significant regulatory action" under the terms of Executive Order 12866. VII. Unfunded Mandates Reform Act Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), Pub. L. 104-4, establishes requirements for Federal agencies to assess the effects of their regulatory actions on State, local, and Tribal governments and the private sector. Under UMRA section 202, EPA generally must prepare a written statement, including a cost -benefit analysis, for proposed and final riles with "Federal mandates" that may result in expenditures to State, local, and Tribal governments, in the aggregate, or to the private sector, of $100 million or more in any one year. Before promulgating an EPA rule for which a written statement is needed, UMRA § 205 generally requires EPA to identify and consider a reasonable number of regulatory alternatives and adopt the least costly, most cost- effective or least burdensome alternative that achieves the objectives of the rule. The provisions of UMRA § 205 do not apply when they are inconsistent with applicable law. Moreover, UMRA § 205 allows EPA to adopt an alternative other than the least costly, most cost-effective or least burdensome alternative if the Administrator publishes an explanation with the final rule why the alternative was not adopted. Before EPA establishes any regulatory requirements that may significantly or uniquely affect small governments, including Tribal governments, it must have developed under UMRA § 203 a small government agency plan. The plan must provide for notifying potentially affected small governments, enabling officials of affected small governments to have meaningful and timely input in the development of EPA regulatory proposals with significant Federal intergovernmental mandates, and informing, educating and advising small governments on compliance with the regulatory requirements. A. UMRA Section 202 and the Construction General Permit UMRA § 202 requires a written statement containing certain assessments, estimates and analyses prior to the promulgation of certain general notices of proposed rulemaking (2 U.S.C. 1532). UMRA § 421 (10) defines 36496 Federal Register / Vol. 63, No. 128 / Monday, July 6, 1998 / Notices "rule" based on the definition of rule in seeking coverage under the permit. if issued as drafted, would not have a the Regulatory Flexibility Act.

(Note that in today's The APA defines two broad, mutually exclusive categories of agency action— ...: permits. EPA envisions that some municipalities—those with municipal action, EPA is issuing a separate general permit for each jurisdiction where EPA "rules" and "orders." Its definition of "rule" encompasses "an agency ... separate storm sewer systems serving a population over 100,000—may elect to issues permits: i.e., in certain States, Indian Country lands and Federal statement of general or particular applicability and future effect designed seek coverage under these proposed general permits.

EPA concluded that the permit, "rules" and not also to "orders," which Federal Register / Vol. 63, No. 128/Monday, July 6, 1998/Notices 36497 include permits. As the Attorney General's Manual on the APA explains, "the entire Act is based upon a dichotomy between rule making and adjudication [the agency process for formulation of an order]" (p. 14). The CWA specifies the use of permits for authorizing the discharge of pollutants to waters of the United States. Section 301(a) of the CWA prohibits discharges of pollutants "[except as in compliance with" specified sections of the CWA, including section 402. 33 U.S.C. 1311(a). Section 402 of the CWA authorizes EPA "to issue a permit for the discharge of any pollutant * * notwithstanding section [301(a) of the CWA]." 33 U.S.C. 1342(a). Thus, the only circumstances in which a discharge of pollution may be authorized is where the Agency has issued a permit for the discharge. Courts, recognizing that a permit is the necessary condition -precedent to any lawful discharge, specifically suggested the use of area -wide and general permits as a mechanism for addressing the Agency's need to issue a substantial number of permits. See NRDC v. Train, 396 F.Supp. 1393, 1402 (D.D.C. 1975); NRDC v. Costle, 568 F.2d 1369, 1381. (D.C. Cir. 1977). Adopting the courts' suggestion, EPA has made increasing use of general permits in its CWA regulatory program, particularly for storm water discharges. In the Agency's view, the fact that an NPDES general permit may apply to a large number of different dischargers does not convert it from a permit into a rule. As noted above, the courts which have faced the issue of how EPA can permit large numbers of discharges under the CWA have suggested use of a general permit, not a rule. Under the APA, the two terms are mutually exclusive. Moreover, an NPDES general permit retains unique characteristics that distinguish a permit from a rule. First, today's NPDES general permit for storm water discharges associated with construction activity is effective only with respect to those dischargers that choose to be bound by the permit. Thus, unlike the typical rule, this NPDES general permit does not impose immediately effective obligations of general applicability. A discharger must choose to be covered by this general permit and so notify EPA. A discharger always retains the option of obtaining its own individual permit. Relatedly, the terms of the NPDES general permit are enforceable only against dischargers that choose to make use of the permit. If a source discharges without authorization of a general or an individual permit, the discharger violates § 301 of the Act for discharging without a permit, not for violating the terms of an NPDES general permit. Because the CWA and its case law make clear that NPDES permits are the congressionally chosen vehicle for authorizing discharges of pollutants to waters of the United States, the APA's rulemaking requirements are inapplicable to issuance of such permits, including today's general permit. Further, while the CWA requires that NPDES permits be issued only after an opportunity for a hearing, it does not require publication of a general notice of proposed rulemaking. Thus, NPDES permitting is not subject to the requirement to publish a general notice of proposed rulemaking under the APA or any other law. Accordingly, it is not subject to the RFA. At the same time, the Agency recognizes that the question of the applicability of the APA, and thus the RFA, to the issuance of a general permit is a difficult one, given the fact that a large number of dischargers may choose to use the general permit. Indeed, the point of issuing a general permit is to provide a speedier means of permitting large number of sources and save dischargers and EPA time and effort. Since the Agency hopes that many dischargers will make use of a general permit and since the CWA requires EPA to provide an opportunity for "a hearing" prior to issuance of a permit, EPA provides the public with notice of a draft general permit and an opportunity to comment on it. From public comments, EPA learns how to better craft a general permit to make it appropriate for, and acceptable to, the largest number of potential permittees. This same process also provides an opportunity for EPA to consider the potential impact of general permit terns on small entities and how to craft the permit to avoid any undue burden on small entities. This process, however, is voluntary, and does not trigger rulemaking or RFA requirements. In the case of the CGP being issued today, the Agency has considered and addressed the potential impact of the general permit on small entities in a manner that would meet the requirements of the RFA if it applied. Specifically, EPA has analyzed the potential impact of the general permit on small entities and found that it will not have a significant economic impact on a substantial number of small entities. Like the previous general permit that it replaces (the Baseline Construction General Permit), the permit will make available to many small entities, particularly operators of construction sites, a streamlined process for obtaining authorization to discharge. Of the possible permitting mechanisms available to dischargers subject to the CWA, NPDES general permits are designed to reduce the reporting and monitoring burden associated with NPDES permit authorization, especially for small entities with discharges having comparatively less potential for environmental degradation than discharges typically regulated under individual NPDES permits. Thus, general permits like the permit at issue here provide small entities with a permitting application option that is much less burdensome than NPDES individual permit applications. Furthermore, the general permit is virtually identical to its predecessor, the Baseline Construction General Permit, under which many construction operators have operated during the past five years. Moreover, the other new provisions of the permit have been designed to minimize burdens on small entities, including eliminating the requirement that construction site operators require that their contractors and subcontractors sign a standard certification statement agreeing to abide by storm water pollution prevention plan provisions developed for a project. In today's general permit, only the operator(s) of a construction site are required to satisfy certification requirements under the permit. EPA believes this modification from the prior permit should reduce any such adverse economic impacts on both operators and contractors/subcontractors who, in many instances, are small entities. In view of the foregoing, the Regional Administrators find that the final general permit, even if it were a rule, will not have a significant economic impact on a substantial number of small entities.

(2) Coverage under this permit is available only if the applicant certifies that it meets at least one of the criteria in paragraphs (a)—(d) below. Failure to continue to meet one of these criteria during the term of the permit will render a permittee ineligible for coverage under this permit. (a) The storm water discharges and storm water discharge -related activities are not likely to adversely affect listed species or critical habitat; or (b) Formal or informal consultation with the Fish and Wildlife Service and/ or the National Marine Fisheries Service (the "Services") under section 7 of the Endangered Species Act (ESA) has been concluded which addresses the effects of the applicant's storm water discharges and storm water discharge - related activities on listed species and critical habitat and the consultation results in either a no jeopardy opinion or a written concurrence by the Service(s) on a finding that the applicant's storm water discharges and storm water discharge -related activities are not likely to adversely affect listed species or critical habitat. A section 7 consultation may occur in the context of another Federal action (e.g., a ESA section 7 consultation was performed for issuance of a wetlands dredge and fill permit for the project, or as part of a National Environmental Policy Act (NEPA) review); or (c) The applicant's construction activities are authorized under section 10 of the ESA and that authorization addresses the effects of the applicant's storm water discharges and storm water discharge -related activities on listed species and critical habitat; or (d) The applicant's storm water discharges and storm water discharge - related activities were already addressed in another operator's certification of eligibility under Part I.B.3.e. (2) (a), (b), or (c) which included the applicant's project area. By certifying eligibility under Part I.B.3.e. (2) (d), the applicant agrees to comply with any measures or controls upon which the other operator's certification under Part I.B.3.e.(2)(a), (b) or (c) was based. (3) For all projects commencing construction after the effective date of this permit, applicants must follow the procedures provided at Addendum A of this permit when applying for permit coverage. The Director may also require any existing permittee or applicant to provide documentation of eligibility for this permit using the procedures in Addendum A, where EPA or the Fish and Wildlife Services determine that there is a potential impaction on endangered or threatened species or a critical habitat. Nothing in this permit relieves applicants which are under construction as of the effective date of this permit of their obligations they may have to comply with any requirements of the Endangered Species Act. (4) The applicant must comply with any applicable terns, conditions or other requirements developed in the process of meeting eligibility requirements of Part I.B.3.e. (2) (a), (b), (c), or (d) above to remain eligible for coverage under this permit. Such terms and conditions must be incorporated in the applicant's storm water pollution prevention plan. (5) Applicants who choose to conduct informal consultation to meet the eligibility requirements of Part I.B.3.e. (2) (b) are automatically designated as non -Federal representatives under this permit. See 50 CFR 402.08. Applicants who choose to conduct informal consultation as a non -Federal representatives must notify EPA and the appropriate Service office in writing of that decision. (6) This permit does not authorize any storm water discharges where the discharges or storm water discharge - related activities cause prohibited "take" (as defined under section 3 of the Endangered Species Act and 50 CFR 17.3) of endangered or threatened species unless such takes are authorized under sections 7 or 10 of the Endangered Species Act. (7) This permit does not authorize any storm water discharges where the discharges or storm water discharge - related activities are likely to jeopardize the continued existence of any species that are listed or proposed to be listed as endangered or threatened under the ESA or result in the adverse modification or destruction of habitat that is designated or proposed to be designated as critical under the ESA. f. Storm water Discharges and Storm Water Discharge -Related Activities with Unconsidered Adverse Effects on Historic Properties. (Reserved) C. Obtaining Authorization 1. In order for storm water discharges from construction activities to be authorized under this general permit, an operator must: a. Meet the Part I.B eligibility requirements; b. Except as provided in Parts II.A.5 and II.A.6, develop a storm water pollution prevention plan (SWPPP) covering either the entire site or all portions of the site for which they are operators (see definition in Part IX.N) according to the requirements in Part IV. A ';joint" SWPPP may be developed and implemented as a cooperative effort where there is more than one operator at a site; and c. Submit a Notice of Intent (NOI) in accordance with the requirements of Part II, using an NOI form provided in Addendum C of this permit. Only one NOI need be submitted to cover all of the permittee's activities on the common plan of development or sale (e.g., you do not need to submit a separate NOI for each separate lot in a residential subdivision or for two separate buildings being constructed at a manufacturing facility, provided your SWPPP covers each area for which you are an operator). The SWPPP must be implemented upon commencement of construction activities. 2. Any new operator on site, including those who replace an operator who has previously obtained permit coverage, must submit an NOI to obtain permit coverage. 3. Unless notified by the Director to the contrary, operators who submit a correctly completed NOI in accordance with the requirements of this permit are authorized to discharge storm water from construction activities under the terms and conditions of this permit two (2) days after the date that the NOI is postmarked. The Director may deny coverage under this permit and require submittal of an application for an individual NPDES permit based on a review of the NOI or other information (see Part VI.Q. D. Terminating Coverage 1. Permittees wishing to terminate coverage under this permit must submit a Notice of Termination (NOT) in accordance with Part VIII of this permit. Compliance with this permit is required until an NOT is submitted. The permittee's authorization to discharge under this permit terminates at midnight of the day the NOT is signed. 2. All permittees must submit a NOT within thirty (30) days after one or more of the following conditions have been met: a. Final stabilization (see definition Part IX.I) has been achieved on all portions of the site for which the permittee is responsible (including if applicable, returning agricultural land to its pre -construction agricultural use); b. Another operator/permittee has assumed control according to Part VI.G.2.c. over all areas of the site that have not been finally stabilized; or c. For residential construction only, temporary stabilization has been completed and the residence has been transferred to the homeowner.

B. Releases in Excess of Reportable Quantities The discharge of hazardous substances or oil in the stone water discharge(s) from a facility shall be prevented or minimized in accordance with the applicable storm water pollution prevention plan for the facility. This permit does not relieve the permittee of the reporting requirements of 40 CFR 110, 40 CFR 117 and 40 CFR 302. Where a release containing a hazardous substance or oil in an amount equal to or in excess of a reportable quantity established under either 40 CFR 110, 40 CFR 117 or 40 CFR 302, occurs during a 24 hour period: 1. The permittee is required to notify the National Response Center (NRC) (800-424-8802; in the Washington, DC, metropolitan area call 202-426-2675) in accordance with the requirements of 40 CFR 110, 40 CFR 117 and 40 CFR 302 as soon as he or she has knowledge of the discharge; 2. The storm water pollution prevention plan required under Part IV of this permit must be modified within 14 calendar days of knowledge of the release to: provide a description of the release, the circumstances leading to the release, and the date of the release. In addition, the plan must be reviewed to identify measures to prevent the reoccurrence of such releases and to respond to such releases, and the plan must be modified where appropriate. C. Spills This permit does not authorize the discharge of hazardous substances or oil resulting from an on-site spill. D. Discharge Compliance With Water Quality Standards Operators seeking coverage under this permit shall not be causing or have the reasonable potential to cause or contribute to a violation of a water quality standard. Where a discharge is already authorized under this permit and is later determined to cause or have the reasonable potential to cause or contribute to the violation of an applicable water quality standard, the Director will notify the operator of such violation(s). The permittee shall take all necessary actions to ensure future discharges do not cause or contribute to the violation of a water quality standard and document these actions in the storm water pollution prevention plan. If violations remain or re -occur, then coverage under this permit may be terminated by the Director, and an alternative general permit or individual permit may be issued. Compliance with this requirement does not preclude any enforcement activity as provided by the Clean Water Act for the underlying violation. E. Responsibilities of Operators Permittees may meet one or both of the operational control components in the definition of "operator" found in Part IX.N. Either Parts III.E.1 or III.E.2 or both will apply depending on the type of operational control exerted by an individual permittee. Part III.E.3 applies to all permittees. 1. Permittees with operational control over construction plans and specifications, including the ability to make modifications to those plans and specifications (e.g., developer or owner), must: a. Ensure the project specifications that they develop meet the minimum requirements of Part IV (Storm Water Pollution Prevention Plans (SWPPP)) and all other applicable conditions; b. Ensure that the SWPPP indicates the areas of the project where they have operational control over project specifications (including the ability to make modifications in specifications), and ensure all other permittees implementing portions of the SWPPP impacted by any changes they make to the plan are notified of such modifications in a timely manner; and c. Ensure that the SWPPP for portions of the project where they are operators indicates the name and NPDES permit number for parties with day-to-day operational control of those activities necessary to ensure compliance with the SWPPP or other permit conditions. If these parties have not been identified at the time the SWPPP is initially developed, the permittee with operational control over project specifications shall be considered to be the responsible party until such time as the authority is transferred to another party (e.g., general contractor) and the plan updated. 2. Permittee(s) with day-to-day operational control of those activities at a project which are necessary to ensure compliance with a SWPPP for the site or other permit conditions (e.g., general contractor) must: a. Ensure that the SWPPP for portions of the project where they are operators meets the minimum requirements of Part IV (Storm Water Pollution Prevention Plan) and identifies the parties responsible for implementation of control measures identified in the plan; b. Ensure that the SWPPP indicates areas of the project where they have operational control over day-to-day activities; c. Ensure that the SWPPP for portions of the project where they are operators indicates the name and NPDES permit number of the party(ies) with operational control over project specifications (including the ability to make modifications in specifications); 3. Permittees with operational control over only a portion of a larger construction project (e.g., one of four homebuilders in a subdivision) are responsible for compliance with all applicable terms and conditions of this permit as it relates to their activities on their portion of the construction site, including protection of endangered species and implementation of BMPs and other controls required by the SWPPP. Permittees shall ensure either directly or through coordination with other permittees, that their activities do not render another party's pollution controls ineffective. Permittees must either implement their portions of a common SWPPP or develop and implement their own SWPPP. F. Consistency With the Texas Coastal Management Program This permit does not relieve permittees whose construction project is located within the boundary of the Texas Coastal Management Program of their responsibility to insure consistency with all applicable requirements of this State program. While pre -construction approval of development projects is not within the jurisdiction of the Federal NPDES permit program, State or local pre - construction project approvals and/or permits may be required. The permittee's Storm Water Pollution Prevention Plan must be consistent with any storm water discharge -related requirements established pursuant to, or necessary to be consistent with, the Texas Coastal Management Program. This permit may be reopened, upon petition by the State, to include more stringent discharge requirements applying to areas within the State's designated coastal zone. The Texas Coastal Management Program boundary covers part or all of the following Texas Counties: Aransas, Brazoria, Calhoun, Cameron, Chambers, Galveston, Harris, Jackson, Jefferson, Kenedy, Kleberg, Matagorda, Nueces, Orange, Refugio, San Patricio, Victoria, and Willacy. To determine if a construction project is located within the Texas Coastal Zone, and if so, the applicable requirements of the Texas Coastal Management Program, please 36502 Federal Register / Vol. 63, No. 128/Monday, July 6, 1998/Notices contact the Texas General Land Office's Coastal Hotline at 1 -800 -85 -BEACH or access their Internet site at "http:// red.glo.state.tx.us/res-mgmt/coastal/". Information is also available from the Texas Coastal Coordination Council's Coastal Permitting Assistance Office at 1-888-3—PERMIT or via the Internet at "http://red.glo.state.tx.us/ coastalpermits/". Part IV. Storm Water Pollution Prevention Plans At least one storm water pollution prevention plan (SWPPP) shall be developed for each construction project or site covered by this permit. For more effective coordination of BMPs and opportunities for cost sharing, a cooperative effort by the different operators at a site to prepare and participate in a comprehensive SWPPP is encouraged. Individual operators at a site may, but are not required, to develop separate SWPPPs that cover only their portion of the project provided reference is made to other operators at the site. In instances where there is more than one SWPPP for a site, coordination must be conducted between the permittees to ensure the storm water discharge controls and other measures are consistent with one another (e.g., provisions to protect listed species and critical habitat). Storm water pollution prevention plans shall'be prepared in accordance with good engineering practices. The SWPPP shall identify potential sources of pollution which may reasonably be expected to affect the quality of storm water discharges from the construction site. The SWPPP shall describe and ensure the implementation of practices which will be used to reduce the pollutants in storm water discharges associated with construction activity at the construction site and assure compliance with the terms and conditions of this permit. When developing SWPPPs, applicants must follow the procedures in Addendum A of this permit to determine whether listed endangered or threatened species or critical habitat would be affected by the applicant's storm water discharges or storm water discharge -related activities. Any information on whether listed species or critical habitat are found in proximity to the construction site must be included in the SWPPP. Any terms or conditions that are imposed under the eligibility requirements of Part I.B.3.e and Addendum A of this permit to protect listed species or critical habitat from storm water discharges or storm water discharge -related activity must be incorporated into the SWPPP. Permittees must implement the applicable provisions of the SWPPP required under this part as a condition of this permit. A. Deadlines for Plan Preparation and Compliance The storm water pollution prevention plan shall: 1. Be completed prior to the submittal of an NOI to be covered under this permit (except as provided in Parts ILA.5 and II.A.6) updated as appropriate, and 2. Provide for compliance with the terms and schedule of the SWPPP beginning with the initiation of construction activities. B. Signature, Plan Review and Making Plans Available 1. The SWPPP shall be signed in accordance with Part VI.G, and be retained on-site at the facility which generates the storm water discharge in accordance with Part V (Retention of Records) of this permit. 2.. The permittee shall post a notice near the main entrance of the construction site with the following information: a. The NPDES permit number for the project or a copy of the NOI if a permit number has not yet been assigned; b. The name and telephone number of a local contact person; c. A brief description of the project; and d. The location of the SWPPP if the site is inactive or does not have an on- site location to store the plan. If posting this information near a main entrance is infeasible due to safety concerns, the notice shall be posted in a local public building. If the construction project is a linear construction project (e.g., pipeline, highway, etc.), the notice must be placed in a publicly accessible location near where construction is actively underway and moved as necessary. This permit does not provide the public with any right to trespass on a construction site for any reason, including inspection of a site; nor does this permit require that permittees allow members of the public access to a construction site. 3. The permittee shall make SWPPPs available upon request to the Director, a State, Tribal or local agency approving sediment and erosion plans, grading plans, or storm water management pians; local government officials; or the operator of a municipal separate storm sewer receiving discharges from the site. The copy of the SWPPP that is required to be kept on-site or locally available must be made available to the Director for review at the time of an on-site inspection. Also, in the interest of public involvement, EPA encourages permittees to make their SWPPPs available to the public for viewing during normal business hours. 4. The Director may notify the permittee at any time that the SWPPP does not meet one or more of the minimum requirements of this Part. Such notification shall identify those provision of this permit which are not being met by the SWPPP as well as those requiring modification in order to meet the minimum requirements of this Part. Within seven (7) calendar days of receipt of such notification from the Director (or as otherwise provided by the Director), the permittee shall make the required changes to the SWPPP and shall submit to the Director a written certification that the requested changes have been made. The Director may take appropriate enforcement action for the period of time the permittee was operating under a plan that did not meet the minimum requirements of this permit. C. Keeping Plans Current The permittee must amend the storm water pollution prevention plan whenever: 1. There is a change in design, construction, operation, or maintenance which has a significant effect on the discharge of pollutants to the waters of the United States which has not been addressed in the SWPPP; or �— 2. Inspections or investigations by site operators, local, State, Tribal or Federal officials indicate the SWPPP is proving ineffective in eliminating or significantly minimizing pollutants from sources identified under Part IV.D.1 of this permit, or is otherwise not achieving the general objectives of controlling pollutants in storm water discharges associated with construction activity. D. Contents of Plan The storm water pollution prevention plan (SWPPP) shall include the following items: 1. Site Description Each SWPPP shall provide a description of potential pollutant sources and other information as indicated below: a. A description of the nature of the construction activity; b. A description of the intended sequence of major activities which disturb soils for major portions of the site (e.g., grubbing, excavation, grading, utilities and infrastructure installation); c. Estimates of the total area of the site and the total area of the site that is Federal Register / Vol. 63, No. 128/Monday, July 6, 1998/Notices 36503 expected to be disturbed by excavation, grading, or other activities including off- site borrow and fill areas; d. An estimate of the runoff coefficient of the site for both the pre - construction and post -construction conditions and data describing the soil or the quality of any discharge from the site; e. A general location map (e.g., a portion of a city or county map) and a site map indicating the following: drainage patterns and approximate slopes anticipated after major grading, activities; areas of soil disturbance; areas which will not be disturbed; locations of major structural and nonstructural controls identified in the SWPPP; locations where stabilization _ practices are expected to occur; locations of off-site material, waste, borrow or equipment storage areas; surface waters (including wetlands); and locations where storm water discharges to a surface water; L Location and description of any discharge associated with industrial activity other than construction, including storm water discharges from dedicated asphalt plants and dedicated concrete plants, which is covered by this permit; g. The name of the receiving water(s) and the areal extent and description of wetland or other special aquatic sites (as described under 40 CFR 230.3(q-1)) at or near the site which will be disturbed or which will receive discharges from disturbed areas of the project; h. A copy of the permit requirements (attaching a copy of this permit is acceptable); i. Information on whether listed endangered or threatened species, or critical habitat, are found in proximity to the construction activity and whether such species may be affected by the applicant's storm water discharges or storm water discharge -related activities; and j. Information on whether storm water discharges or storm water discharge - related activities would have an affect on a property that is listed or eligible for listing on the National Register of Historic Places; where effects may occur, any written agreements with the State Historic Preservation Officer: Tribal Historic Preservation Officer, or other Tribal leader to mitigate those effects. 2. Controls Each SWPPP shall include a description of appropriate control measures (i.e., BMPs) that will be implemented as part of the construction activity to control pollutants in storm water discharges. The SWPPP must clearly describe for each major activity identified in Part IV.D.l.b: (a) appropriate control measures and the general timing (or sequence) during the construction process that the measures will be implemented; and (b) which permittee is responsible for implementation (e.g., perimeter controls for one portion of the site will be installed by Contractor A after the clearing and grubbing necessary for installation of the measure, but before the clearing and grubbing for the remaining portions of the site; and perimeter controls will be actively maintained by Contractor B until final stabilization of those portions of the site up -gradient of the perimeter control; and temporary perimeter controls will be removed by the owner after final stabilization). The description and implementation of control measures shall address the following minimum components: a. Erosion and Sediment Controls. (1) Short and Long Term Goals and Criteria: (a) The construction -phase erosion and sediment controls should be designed to retain sediment on site to the extent practicable. (b) All control measures must be properly selected, installed, and maintained in accordance with the manufacturers specifications and good engineering practices. If periodic inspections or other information indicates a control has been used inappropriately, or incorrectly, the permittee must replace or modify the control for site situations. (c) If sediment escapes the construction site, off-site accumulations of sediment must be removed at a frequency sufficient to minimize offsite impacts (e.g., fugitive sediment in street could be washed into storm sewers by the next rain and/or pose a safety hazard to users of public streets).

(2) Stabilization Practices: The SWPPP must include a description of interim and permanent stabilization practices for the site, including a schedule of when the practices will be implemented. Site plans should ensure that existing vegetation is preserved where attainable and that disturbed portions of the site are stabilized. Stabilization practices may include but are not limited to: establishment of temporary vegetation, establishment of permanent vegetation, mulching, geotextiles, sod stabilization, vegetative buffer strips, protection of trees, preservation of mature vegetation, and other appropriate measures. Use of impervious surfaces for stabilization should be avoided. The following records shall be maintained and attached to the SWPPP: the dates when major grading activities occur: the dates when construction activities temporarily or permanently cease on a portion of the site; and the dates when stabilization measures are initiated. Except as provided in Parts IV.D.2.a.(2)(a), (b), and (c) below, stabilization measures shall be initiated as soon as practicable in portions of the site where construction activities have temporarily or permanently ceased, but in no case more than 14 days after the construction activity in that portion of the site has temporarily or permanently ceased.

In some parts of the country, background native vegetation will cover less than 100% of the ground (e.g., and areas, beaches). Establishing at least 70% of the natural cover of native vegetation meets the vegetative cover criteria for final stabilization (e.g., if the native vegetation covers 50% of the ground, 70% of 50% would require 3596 total cover for final stabilization; on a beach with no natural vegetation, no stabilization is required); or 2. For individual lots in residential construction by either: (a) the homebuiider completing final stabilization as specified above, or (b) the homebuilder establishing temporary stabilization including perimeter controls for an individual lot prior to occupation of the home by the homeowner and informing the homeowner of the need for, and benefits of, final stabilization. (Homeowners typically have an incentive to put in landscaping functionally equivalent to final stabilization as quick as possible to keep mud out of their homes and off their sidewalks and driveways.); or 3. For construction projects on land used for agricultural purposes (e.g., pipelines across crop or range land), final stabilization may be accomplished by returning the disturbed land to its preconstruction agricultural use. Areas disturbed that were not previously used for agricultural activities, such as buffer strips immediately adjacent to "waters of the United States," and areas which are not being returned to their preconstruction agricultural use must meet the final stabilization criteria in (1) or (2) above. J. Flow -Weighted Composite Sample means a composite sample consisting of a mixture of aliquots collected at a constant time interval, where the volume of each aliquot is proportional to the flow rate of the discharge. K. Large and Medium Municipal Separate Storm Sewer System means all municipal separate storm sewers that are either: 1. Located in an incorporated place (city) with a population of 100,000 or more as determined by the latest Decennial Census by the Bureau of Census (these cities are listed in Appendices F and G of 40 CFR 122); or 2. Located in the counties with unincorporated urbanized populations of 100,000 or more, except municipal separate storm sewers that are located in the incorporated places, townships or towns within such counties (these counties are listed in Appendices H and I of 40 CFR 122); or 3. Owned or operated by a municipality other than those described in paragraph (i) or (ii) and that are designated by the Director as part of the large or medium municipal separate storm sewer system. L. NOI means Notice of Intent to be covered by this permit (see Part 11 of this permit). M. NOT means Notice of Termination (see Part VIII of this permit). N. Operator for the purpose of this permit and in the context of storm water associated with construction activity, means any party associated with a construction project that meets either of the following two criteria: 1. The party has operational control over construction plans and specifications, including the ability to make modifications to those plans and specifications; or 2. The party has day-to-day operational control of those activities at a project which are necessary to ensure compliance with a storm water pollution prevention plan for the site or other permit conditions (e.g., they are authorized to direct workers at a site to carry out activities required by the SWPPP or comply with other permit conditions). This definition is provided to inform permittees of EPA's interpretation of how the regulatory definitions of "owner or operator" and "facility or activity" are applied to discharges of storm water associated with construction activity. O. Owner or operator means the owner or operator of any "facility or activity" subject to regulation under the NPDES program. P. Point Source means any discernible, confined, and discrete conveyance, including but not limited to, any pipe, ditch, channel, tunnel, conduit, well, discrete fissure, container, rolling stock, concentrated animal feeding operation, landfill leachate collection system, vessel or other floating craft from which pollutants are or may be discharged. This term does not include return flows from irrigated agriculture or agricultural storm water runoff. Q. Pollutant is defined at 40 CFR 122.2. A partial listing from this definition includes: dredged spoil, solid waste, sewage, garbage, sewage sludge, chemical wastes, biological materials, heat, wrecked or discarded equipment, rock, sand, cellar dirt, and industrial or municipal waste. R. Runoff coefficient means the fraction of total rainfall that will appear at the conveyance as runoff. S. Storm Water means storm water runoff, snow melt runoff, and surface runoff and drainage. T. Storm Water Associated With Industrial Activity is defined at 40 CFR 122.26(b)(14) and incorporated here by reference. Most relevant to this permit is 40 CFR 122.26(b)(14)(x), which relates to construction activity including clearing, grading and excavation activities that result in the disturbance of five (5) or more acres of total land area, or are part of a larger common plan of development or sale. U. Waters of the United States means: 1. All waters which are currently used, were used in the past, or may be susceptible to use in interstate or foreign commerce, including all waters which are subject to the ebb and flow of the tide; 2. All interstate waters, including interstate "wetlands"; 3. All other waters such as interstate lakes, rivers, streams (including intermittent streams), mudflats, sandflats, wetlands, sloughs, prairie potholes, wet meadows, playa lakes, or natural ponds, the use, degradation, or destruction of which would affect or could affect interstate or foreign commerce including any such waters: a. Which are or could be used by interstate or foreign travelers for recreational or other purposes; b. From which fish or shellfish are or could be taken and sold in interstate or foreign commerce; or c. Which are used or could be used for industrial purposes by industries in interstate commerce; 4. All impoundments of waters otherwise defined as waters of the United States under this definition; 5. Tributaries of waters identified in paragraphs (a) through (d) of this definition; 6.

Background To meet its obligations under the Clean Water Act and the Endangered Species Act (ESA) and to promote those Acts' goals, the Environmental Protection Agency (EPA) is seeking to ensure the activities regulated by the Construction General Permit (CGP) are protective of endangered and threatened species and critical habitat. To ensure that those goals are met, applicants for CGP coverage are required under Part I.B.3.e. to assess the impacts of their storm water discharges and storm water discharge -related activities on Federally listed endangered and threatened species ("listed species") and designated critical habitat ("critical habitat") by following Steps One through Six listed below. EPA strongly recommends that applicants follow these steps at the earliest possible stage to ensure that measures to protect listed species and critical habitat are incorporated early in the planning process. At minimum, the procedures should be followed when developing the storm water pollution prevention plan. Permittees and applicants also have an independent ESA obligation to ensure that their activities do not result in any prohibited "takes" of listed species.' Many of the measures required in the CGP and in these instructions to protect species may also assist permittees in ensuring that their construction activities do not result in a prohibited take of species in violation of § 9 of the ESA. Applicants who plan construction activities in areas that harbor endangered and threatened species are advised to ensure that I Section 9 of the ESA prohibits any person from "taking" a listed species (e.g., harassing or harming it) unless: (1) the taking is authorized through a "incidental take statement" as part of undergoing ESA § 7 formal consultation; (2) where an incidental take permit is obtained under ESA § 10 (which requires the development of a habitat conservation plan); or (3) where otherwise authorized or exempted under the ESA. This prohibition applies to all entities including private individuals, businesses, and governments. I -- certification of eligibility under Part I.B.3.e.(2)(a), (b), or (c). This is allowed under Part I.13.3.e.(2)(d) of the permit. However, the other operator's certification must apply to the applicant's project area and must address the effects from the applicant's storm water discharges and storm water discharge -related activities on listed species and critical habitat. By certifying eligibility under Part I.B. 3.e. (2) (d), the applicant agrees to comply with any measures or controls upon which the other operator's certification under Part I.13.3.e.(2)(a), (b) or (c) was based. This situation will typically occur where a developer or primary contractor, such as one for construction of a subdivision or industrial park, conducts a comprehensive assessment of effects on listed species and critical habitat for the entire construction project, certifies eligibility under Part I.B.3.e. (2) (a), (b) or (c), and that certification is relied upon by other operators (i.e., contractors) at the site. However, applicants that consider relying on another operator's certification should carefully review that certification along with any supporting information. If an applicant does not believe that the operator's certification provides adequate coverage for the applicant's storm water discharges and storm water discharge -related activities or for the applicant's particular project area, the applicant should provide its own independent certification under Part I.13.3.e.(2)(a), (b), or (c). B. Procedures To receive coverage under the Construction General Permit, applicants must assess the potential effects of their storm water discharges and storm water discharge -related activities on listed species and their critical habitat. To make this assessment, applicants must follow the steps outlined below prior to completing and submitting Notice of Intent (NOD form. Applicants who are able to certify eligibility under Parts I.13.3.e.(2)(b), (c) or (d) because of a previously issued ESA § 10 permit, a previously completed ESA § 7 consultation, or because the applicant's activities were already addressed in another operator's certification of eligibility may proceed directly to Step Six. Step One: Determine if the Construction Site Is Found Within Designated Critical Habitat for Listed Species Some, but not all, listed species have designated critical habitat. Exact locations of such habitat is provided in the Service regulations at 50 CFR Parts 17 and 226. To determine if their construction site occurs within designated critical habitat, applicants should either. • Contact the nearest Fish and Wildlife Service (FWS) and National Marine Fisheries Service (NMFS) Office. A list of FWS and NMFS offices is found in Section II of this Addendum; or • Contact the State or Tribal Natural Heritage Centers. These centers compile and disseminate information on Federally listed and other protected species. They frequently have the most current information on listed species and critical habitat. A list of these centers is provided in Section III of this Addendum; or • Review those regulations (which can be found in many larger libraries). If the construction site is not located in designated critical habitat, then the applicant does not need to consider impacts to critical habitat when following Steps Two through Six below. If the site is located within critical habitat, then the applicant must look at impacts to critical habitat when following Steps Two through Six. Note that many but not all measures imposed to protect listed species under these steps will also protect critical habitat. Thus, meeting the eligibility requirements of this permit may require measures to protect critical habitat that are separate from those to protect listed species. Step Two: Determine if Listed Species Are Located in the County(les) Where the Construction Activity Will Occur Section IV of the Addendum contains a county -by -county list of listed endangered and threatened species ("listed species"), and proposed endangered and threatened species ("proposed species"). Since the list was current as of September 1, 1997, applicants must also check with other sources for updated species and county information. review the species list for the county which lies immediately downstream or is across the water body from the point of discharge. After a review of the available information from the sources mentioned above, if no listed species are located in a facility's county or if a facility's county is not listed, and the construction site is not Iocated in critical habitat as described under Step One, an applicant is eligible for CGP coverage without further inquiry into the presence of, or effect to, listed species. The applicant must check the appropriate certification item on the revised NOI form (Part I.B.3.e. (2) (a)). Once the applicant has determined which listed species are located in his or her facility's county, the applicant must follow Step Three. Step Three: Determine if any Federally Listed Endangered and Threatened Species May Be Present in the Project Area The project area consists of: • The areas on the construction site where storm water discharges originate and flow toward the point of discharge into the receiving waters (including areas where excavation, site development, or other ground disturbance activities occur) and the immediate vicinity. Example(s) 1. Where bald eagles nest in a tree that is on or bordering a construction site and could be disturbed by the construction activity. 2. Where grading causes storm water to flow into a small wetland or other habitat that is on the site which contains listed species. • The areas where storm water discharges flow from the construction site to the point of discharge into receiving waters. Example(s) 1. Where storm water flows into a ditch, swale, or gully which leads to receiving waters and where listed species (such as amphibians) are found in the ditch, swale, or gully. • The areas where storm water from construction activities discharge into receiving waters and the areas in the immediate vicinity of the point of discharge. t 36512 Federal Register / Vol. 63, No. 128/Monday, July 6, 1998 / Notices they are protected from potential takings Note. -The revised NOI form which was These sources include: Sections II and III of liability under ESA § 9 by obtaining either an included in the CGP (see 62 FR 29822-29823, this Addendum; EPA's Office of Wastewater ESA § 10 permit or by requesting formal June 2, 1997) requires that applicants provide Management's web page at" http:H �.-. consultation under ESA § 7 (as described in detailed certification information on listed www.epa.gov/owm" where updates of the more detail in Step Seven below).

This is allowed under Part I.13.3.e.(2)(d) of the permit. However, the other operator's certification must apply to the applicant's project area and must address the effects from the applicant's storm water discharges and storm water discharge -related activities on listed species and critical habitat. By certifying eligibility under Part I.B. 3.e. (2) (d), the applicant agrees to comply with any measures or controls upon which the other operator's certification under Part I.13.3.e.(2)(a), (b) or (c) was based. This situation will typically occur where a developer or primary contractor, such as one for construction of a subdivision or industrial park, conducts a comprehensive assessment of effects on listed species and critical habitat for the entire construction project, certifies eligibility under Part I.B.3.e. (2) (a), (b) or (c), and that certification is relied upon by other operators (i.e., contractors) at the site.

Step Three: Determine if any Federally Listed Endangered and Threatened Species May Be Present in the Project Area The project area consists of: • The areas on the construction site where storm water discharges originate and flow toward the point of discharge into the receiving waters (including areas where excavation, site development, or other ground disturbance activities occur) and the immediate vicinity. Example(s) 1. Where bald eagles nest in a tree that is on or bordering a construction site and could be disturbed by the construction activity. 2. Where grading causes storm water to flow into a small wetland or other habitat that is on the site which contains listed species. • The areas where storm water discharges flow from the construction site to the point of discharge into receiving waters. Example(s) 1. Where storm water flows into a ditch, swale, or gully which leads to receiving waters and where listed species (such as amphibians) are found in the ditch, swale, or gully. • The areas where storm water from construction activities discharge into receiving waters and the areas in the immediate vicinity of the point of discharge. Federal Register / Vol. 63, No. 128/Monday, July 6, 1998/Notices 36513 Example(s) 1. Where storm water from construction activities discharges into a stream segment that is known to harbor listed aquatic species. • The areas where storm water BMPs will be constructed and operated, including any areas where storm water flows to and from BMPs. Example(s) 1. Where a storm water retention pond would be built. The project area will vary with the size and structure of the construction activity, the nature and quantity of the storm water discharges, the storm water discharge -related activities and the type of receiving water. Given the number of construction activities potentially covered by the CGP, no specific method to determine whether listed species may be located in the project area is required for coverage under the CGP. Instead, applicants should use the method which allows them to determine, to the.best of their knowledge, whether listed species are located in their project area. These methods may include: • Conducting visual inspections: This method may be particularly suitable for construction sites that are smaller in size or located in non -natural settings such as highly urbanized areas or industrial parks where there is little or no natural habitat, or for construction activities that discharge directly into municipal storm water collection systems. • Contacting the nearest State or Tribal wildlife agency, the Fish and Wildlife Service (FWS), or the National Marine Fisheries Service (NMFS). Many endangered and threatened species are found in well- defined areas or habitats. Such information is frequently known to State, Tribal, or Federal wildlife agencies. A list of FWS and NMFS offices is provided in Section II of this Addendum below. • Contacting local/regional conservation groups or the State or Tribal Natural Heritage Centers (see Section III of this Addendum). State and local conservation groups may have location specific listed species information. The Natural Heritage Centers inventory species and their locations and maintain lists of sightings and habitats. • Submitting a data request to a Natural Heritage Center. Many of these centers will provide site specific information on the presence of listed species in a project area. Some of these centers will charge a fee for researching data requests. • Conducting a formal biological survey. Larger construction sites with extensive storm water discharges may choose to conduct biological surveys as the most effective way to assess whether species are located in the project area and whether there are likely adverse effects. Biological surveys are frequently performed by environmental consulting firms. A biological survey can be used to follow Steps Four through Six of these instructions. • Conducting an environmental assessment under the National Environmental Policy Act (NEPA). Some construction activities may require environmental assessments under NEPA. Such assessments may indicate if listed species are in the project area. Coverage under the CGP does not trigger such an assessment because the permit does not regulate any dischargers subject to New Source Performance Standards under Section 306 of the Clean Water Act, and is thus statutorily exempted from NEPA. See CWA § 511(c). However, some construction activities might require review under NEPA because of Federal funding or other Federal involvement in the project. If no species are found in the project area, an applicant is eligible for CGP coverage. Applicants must provide the necessary certification on the revised NOI form. If listed species are found in the project area, applicants must indicate the location and nature of this presence in the storm water pollution prevention plan and follow Step Four. Step Four. Determine if Listed Species or Critical Habitat Are Likely To Be Adversely Affected by the Construction Activity's Storm Water Discharges or Storm Water Discharge - Related Activities To receive CGP coverage, applicants must assess whether their storm water discharges or storm water discharge -related activities are likely to adversely affect listed species or critical habitat. "Storm water discharge - related activities" include: • Activities which cause, contribute to, or result in point source storm water pollutant discharges, including but not limited to excavation, site development, grading, and other surface disturbance activities; and • Measures to control storm water discharges including the siting, construction, operation of best management practices (BMPs) to control, reduce or prevent storm water pollution. Potential adverse effects from storm water discharges and storm water discharge -related activities include: • Hydrological. Storm water discharges may cause siltation, sedimentation or induce other changes in receiving waters such as temperature, salinity or pH. These effects will vary with the amount of storm water discharged and the volume and condition of the receiving water. Where a storm water discharge constitutes a minute portion of the total volume of the receiving water, adverse hydrological effects are less likely. Construction activity itself may also alter drainage patterns on a site where construction occurs which can impact listed species or critical habitat. • Habitat. Excavation, site development, grading, and other surface disturbance activities from construction activities, including the installation or placement of storm water BMPs, may adversely affect listed species or their habitat. Storm water may drain or inundate listed species habitat. • Toxicity. In some cases, pollutants in storm water may have toxic effects on listed species. The scope of effects to consider will vary with each site. If the applicant is having difficulty in determining whether his or her project is likely to adversely Affect a listed species or critical habitat, then the appropriate office of the FWS, NMFS or Natural Heritage Center listed in Sections II and III of this Addendum should be contacted for assistance. If adverse effects are not likely, then the applicant should make the appropriate certification on the revised NOI form and apply for coverage under the permit. If adverse effects are likely, applicants must follow Step Five. Step Five: Determine if Measures Can Be Implemented To Avoid Any Adverse Effects If an applicant makes a preliminary determination that adverse effects are likely, it can still receive coverage under Part I.B.3.e.(2)(a) of the CGP if appropriate measures are undertaken to avoid or eliminate the likelihood of adverse effects prior to applying for permit coverage. These measures may involve relatively simple changes to construction activities such as re- routing a storm water discharge to bypass an area where species are located, relocating BMPs, or by changing the "footprint" of the construction activity. Applicants may wish to contact the FWS and/or NMFS to see what appropriate measures might be suitable to avoid or eliminate the likelihood of adverse impacts to listed species and/or critical habitat. (See 50 CFR 402.13(b).) This can entail the initiation of informal consultation with the FWS and/or NMFS which is described in more detail in Step Six. If applicants adopt measures to avoid or eliminate adverse effects, they must continue to abide by those measures during the course of permit coverage. These measures must be described in the storm water pollution prevention plan and may be enforceable as permit conditions. If appropriate measures to avoid the likelihood of adverse effects are not available to the applicant, the applicant must follow Step Six. Step Six: Determine if the Eligibility Requirements of Part LB.3.e.(2)(b)-(d) Can Be Met Where adverse effects are likely, the applicant must contact the EPA and FWS/ NMFS. Applicants may still be eligible for CGP coverage if any likely adverse effects can be addressed through meeting the criteria of Part I.B.3.e.(2)(b)-(d) of the permit. These criteria are as follows: 1. An ESA Section 7 Consultation Is Performed for the Applicant's Activity (See Part I.B.3.e.(2)(b) Formal or informal ESA § 7 consultation is performed with the FWS and/or NMFS which addresses the effects of the applicant's storm water discharges and storm water discharge -related activities on listed species and critical habitat. The formal consultation must result in either a "no jeopardy opinion" or a "jeopardy opinion" that identifies reasonable and prudent alternatives to avoid jeopardy which are to be implemented by the applicant. The informal consultation must result in a written concurrence by the Service(s) on a finding that the applicant's storm water discharge(s) and storm water discharge -related activities are not likely to adversely affect listed species or critical habitat (for informal consultation, see 50 CFR 402.13). 9 36514 Federal Register / Vol. 6,' No. 128/Monday, July 6, 1998/Notices ..w__.,.

Any terms and conditions developed through consultations to protect listed species and critical habitat must be incorporated into the SWPPP. As noted above, applicants may, if they wish, initiate consultation with the Services at Step Five. Whether ESA § 7 consultation must be performed with either the FWS, NMFS or both Services depends on the listed species - which may be affected by the applicant's activity. In general, NMFS has jurisdiction +^ over marine, estuarine, and anadromous species. Applicants should also be aware that while formal § 7 consultation provides protection from incidental takings liability, informal consultation does not. 2. An Incidental Taking Permit Under Section 10 of the ESA Is Issued for the Applicants Activity (See Part I.B.3.e. (2) (c)) The applicant's construction activities are authorized through the issuance of a permit under § 10 of the ESA and that authorization addresses the effects of the applicant's storm water discharge(s) and storm water discharge -related activities on listed species and critical habitat. Applicants must follow FWS and/or NMFS procedures when applying for an ESA Section 10 permit (see 50 CFR § 17.22(b)(1) (FWS) and §222.22 (NMFS)). Application instructions for Section 10 permits for NMFS species can be obtained by (1) accessing the "Office of Protected Resources" sector of the NMFS Home Page at "http://www.nmfs.gov" or by contacting the National Marine Fisheries Service, Office of Protected Resources, Endangered Species Division, F/PR3, 1315 East-West Highway, Silver Spring, Maryland 20910; telephone (301) 713-1401, fax (30 1) 713-0376. 3. The Applicant Is Covered Under the Eligibility Certification of Another Operator for the Project Area (See Part I.B.3.e. (2) (d)) The applicant's storm water discharges and storm water discharge -related activities were already addressed in another operator's certification of eligibility under Part I.13.3.e.(2)(b), or (c) which also included the applicant's project area. By certifying eligibility under Part I.B.3.e.(2)(d), the applicant agrees to comply with any measures or controls upon which the other operator's certification under Part I.B.3.e. (2) (a), (b) or (c) was based. W" II. List of Fish and Wildlife Service and National Marine Fisheries Service Offices A.

Enter the appropriate letter to indicate the legal status of the owner/operator of the project: F = Federal; S = State; M = Public (other than federal or state); P = Private. Section If. Project/Site Information Enter the official or legal name and complete street address, including city, county, state, zip code, and phone number of the project or site. If it lacks a street address, indicate with a general statement the location of the site (e.g., Intersection of State Highways 61 and 34). Complete site information must be provided for permit coverage to be granted. The applicant must also provide the latitude and longitude of the facility in degrees, minutes, and seconds to the nearest 15 seconds. The latitude and longitude of your facility can be located on USGS quadrangle maps. Quadrangle maps can be obtained by calling 1-800 USA MAPS. Longitude and latitude may also be obtained at the Census Bureau Internet site: httpJ/www.census.gov/cgi-bin/gazetteer. Latitude and longitude for a facility in decimal form must be converted to degrees, minutes and seconds for proper entry on the NOI form. To convert decimal latitude or longitude to degrees, minutes, and seconds, follow the steps in the following example. Convert decimal latitude 45.1234567 to degrees, minutes, and seconds. 1) The numbers to the lett of the decimal point are degrees. 2) To obtain minutes, multiply the first four numbers to the right of the decimal point by 0.006. 1234 x .006 = 7.404. 3) The numbers to the left of the decimal point in the result obtained in step 2 are the minutes: 7. 4) To obtain seconds, multiply the remaining three numbers to the right of the decimal from the result in step 2 by 0.06: 404 x 0.06 = 24.24. Since the numbers to the right of the decimal point are not used, the result is 24'. 5) The conversion for 45.1234 = 45° T 24'. Indicate whether the project is on Indian Country Lands. Indicate if the Storm Water Pollution Prevention Plan (SWPPP) has been developed. Refer to Part IV of the general permit for information on SWPPPs.

Ree. 36502] and P_ being retained in accordance with Part V of the Permit. Qualified personnel (provided by the permittee or cooperatively by multiple permittees) shall inspect disturbed areas of the construction site that have not been finally stabilized, areas used for storage of materials that are exposed to precipitation, placement and effectiveness of structural control measures, and locations where vehicles enter or exit the site. Inspections shall be performed at least once every 14 days and within 24 hours of the end of a storm event of 0.5 inches or greater. Where sites have been temporarily stabilized, runoff is unlikely due to winter conditions, or 11 during seasonal arid periods in and areas (0-10 inches of rainfall annually) and semi -arid areas (10-20 inches annually) such inspections shall be conducted at least once every month This form is primarily intended Polkfor use with construction projects in Texas and New Mexico. Permittees on Indian Country lands in Oklahoma, Louisiana and Arkansas and some oil and gas facilities in Oklahoma may use this form if they are eligible for this permit. Other facilities need to check with their NPDES authority before using this form. If you do not know your NPDES Permit Number, contact the NOI Processing Center at (301)195-4145.

Based on my inquiry of the person or persons who manage the system, or those persons directly responsible for gathering the information, the information submitted is, to the best of my knowledge and belief, true, accurate, and complete. I am aware that there are significant penalties for submitting false information, including the possibility of fine and imprisonment for knowing violations. Signature Date Date of Inspection Inspector Name Is there a copy of the permit language • YES 0 NO with the SWPPP? Is the inspector qualified and are the • YES • NO qualifications documented in the - SWPPP? Is an NPDES storm water construction • YES 0 NO sign posted at the entrance for all permittees? You may want to use EPA Region 6 construction checklist to assure components of the SWPPP are complete. This form, the construction sign, and the checklist are available on the Region 6 NPDES Storm Water Forms and Documents web page which may be found on the internet at httl):/hrtivw.eya.gov/earth I r6/6en/w/fotmsw.htm In addition to the checklist, you should provide a narrative (see next page) on the existing Best Management Practices and Structural Controls found during each inspection. Any problems identified in an inspection should be corrected within 7 days. The inspection should cover all components of the SWPPP and all potential pollutants. While eroded soil is the primary pollutant of concern, do not forget to inspect for other pollutant sources such as fuel tanks, paints, solvents, stabilization materials, concrete hardner, batch plants, and construction debris. The inspector will need to update the SWPPP to reflect findings of the inspection. The site map should be updated after an inspection to show controls that have been added or removed, to ensure the site map is kept current in accordance with Part IV.C. of the permit. Revision 4, March 1, 2000 ve Findings of the inspection: Observations should include any findings of Best Management Practices or controls that are not in accordance with the SWPPP. If a control is not in place or failed, observe the reason why. A control removed temporarily for work is not necessarily a violation if properly recorded in the SWPPP. If it has been removed, record why it was removed and, if applicable, when it will be reinstalled. If the control has failed, observe the conditions so a conclusion may be made as to wether the control failed for improper maintenance or improper design. The qualified inspector will know when a failed control is inadequate and should be replaced by an improved control mechanism. Qualified inspectors are to have authority to make changes to the SWPPP to assure compliance. Controls that have not been installed should be given a reason why they are not installed and/or a scheduled date for installation if they are designed for a later phase of construction. After the inspection, the SWPPP and its site map should be updated to reflect current conditions of controls and Best Management Practices at the time of the inspection. This includes removing uninstalled controls from the site map or otherwise denoting on the site map if they are no longer installed if the controls have been removed because they are no longer necessary (e.g. stabilization has been achieved in that area). Revision 4, March 1, 2000 R., By signing this authorization, I confirm that I meet the following requirements to make such a designation as set forth in either Part VI.G.1 of the Construction general permit [63 Fed Reg 36506] or Part 9.7. of the Multi -Sector general permit [65 Fed Reg 64746-64880]. For a corporation: by a responsible corporate officer. For the purpose of this section, a responsible corporate officer means: a president, secretary, treasurer, or vice-president of the corporation in charge of a principal business function or any other person who performs similar policy or decision making functions for the corporation; or the manager of one or more manufacturing, production or operating facilities employing more than 250 persons or having gross annual sales or expenditures exceeding $25,000,000 (in second quarter 1980 dollars) if authority to sign documents has been assigned or delegated to the manager in accordance with corporate procedures. For a partnership or sole proprietorship: by a general partner or the proprietor, respectively. For a municipality, State, Federal or other public agency: by either a principal executive officer or ranking elected official. For purposes of this section, a principal executive officer of a Federal agency includes (1) the chief executive officer of the agency, or (2) a senior executive officer having responsibility for the overall operations of a principal geographic unit of the agency (e.g. Regional Administrators of EPA).

There are no incentives for early completion in this project.v The Owner and Engineer looked at this in great detail during the plan preparation and determined that we could not put k " incentives for early completion in a contract when we are regulating the working hours. The working hours are regulated in specification Section 01140 and Addendum No. 1 paragraph 38. Such regulation of working hours is contradictory to an early completion incentive, therefore an incentive is not'being offered. 5. Drawings, Sheet P33 Ans.

The drainage improvement project contains several bid items intended to covert he hand -ling and disposal of contaminated soil and water. The actual quantities'ofthese materials, particularly in the case of water, and the degree of contamination are very difficult to quantify. In order to cover the uncertainties associated with these items it will be necessary to add contingent costs to these Id items. It would seem that an overall lower cost would be realized by the city of Lubbock if they assumed the risk of tFi'is wow k by performing it on an r,.. Extra Work order basis. We"hereby'' request that you give consideration to performing this work on an Extra Work Order Ans. This request is taken as regards the proximity of some of the known leaking petroleum „1,,, storage tank (LPST) sites along the storm sewer route. There is information in the plans regarding the location of monitor wells that are located on the properties of the applicable LPST sites, and ground water elevation information from TNRCC records for those monitoring wells i,s' shown.

When does the project bid? (This was from an individual who has not seen the plans and specifications). Ans. The date for bid opening at the time of the pre-bid conference was March 22, 2001. The bid opening has now been changed to 3:00 o'clock p.m. on April 23, 2001. 9. Is there a pre-bid meeting and is it mandatory? (This was from an individua1who has not seen the plans and specifications). Ans. Yes, there was a pre-bid meeting and it was scheduled for 9:00 a.m., February 7, 2001, Room 103 at the Lubbock, Texas City Hall. It was non -mandatory as noted in the Notice to Bidders and General Instructions to Bidders. -10. Is most of the project in caliche? (This was from an individual who had not seen the plans and specifications). Ans. It is likely that caliche will be encountered in the project since caliche is common to the area, however it is up to each person reviewing the plans and specifications to draw their own interpretations. Geotechnical reports that were used during design are furnished to plan holders for information -only purposes in accordance with the Special Provisions, paragraph SP -6. 11. Will there be a dispute resolution board set up for the project? (This was from an individual who had not seen the plans and specifications). Ans. According to the Contract Documents andSpecifications, no dispute resolution board is established. 12. What estimate range has been assigned to the project? (This was from 'an individual who had not seen the plans and specifications). Ans. There is no estimate range. The published construction estimate is $30.6 million shown on the City of Lubbock web site. 13. 1 don't want to purchase the full set of plans and specifications. Can I get just the individual +j plan sheets and specification sections that affect the portions of the work that interest me? Ans. No, only complete sets of plans and specifications will be distributed. 14. Is there a spreadsheet available for the bidders that lists the bid items, automatically calculates the extensions, and where an electronic bid can'be submitted? Ans. No, a spreadsheet has not been developed for the bidder's use. Electronic bid submittals are not acceptable as stated in the General Instructions to Bidders, paragraph 1.3. 15. Can pipe types be mixed in the Base Bid? Ans. Yes, to the extent that the pipe is listed as acceptable for a specific storm sewer line. The allowable pipe materials for the Base Bid are listed on sheet G13 of the drawings. For example, Line Al -07 and Line Al -08 list RCP, CCFRP and CIPNRCP as allowable pipe materiah, for those storm sewer reaches (pipe material abbreviations are listed on sheet G13). If the Contractor plans for Line Al-07to be RCP, then the next upstream reach, Line Al -08, does not have to be RCP. There is also a footnote that CIPNRCP is not permissible for the trenchless methods of installation. Therefore, a transition manhole structure will be required between RCP and CIPNRCP, or between CCFRP and CIPNRCP, where such transitions take place at other than a manhole location that is already shown on the drawings. Transitions between RCP and _CCFRP pipe can take place at other than the indicated manhole locations provided the CCFRP pipe has been fabricated with a matching RCP -specified joint. The Contractor is required to Page 4 of 60 f i ITB #001-01/VK, Addendum #1 t a e rial l yingnchedule" as specified in specification Section 02631 as part of the ssubmit mat ubmittalpi r. __.�g. 16. I can't'find where the Worker's Compensation Insurance Experience Rating'of 1.6 is required. Ans. Itis listed on page 4 of the Instructions to Bidders, paragraph 9.3'. 17. What type of contamination was there from the LPSTsites'identified in the TNRCC records? " Ans., As best as can be determined from the records photocopied for design purposes from the TN RCC District 2 Field Office, it looks like gasoline and diesel are the primary products originally released. The LPST sites are listed on sheet G11 of the drawings. During the design phase soih, samples were retrieved from Test Holes 14, 19, 20,'21,'22 24; 26, 30, 31, arid 35 (these-test holes 3 are shown on the drawings) and tested for Total Petroleum Hydrocarbons. The sampling intervals and results for,Total Petroleum Hydrocarbons (TPH) were: Test Hole Number Sampling Interyal TPH Results 14 10=25 feet at 546ot intervals Below detection limits 19 10-30 feet at 5-foot intervals Below detection limits 20 10-30 feet at 5-foot intervals Below detection limits 21 ' 10=30 feet at 5-foot intervalsBelow detectionlimits ""' 22 10-45 feet at 5-foot interyals Below detection limits 24 10-46 feet at5-foot intervals Below detection limits to 35 feet 61 mg/kg at 35 feet <100 mg/Kg at 40 feet* *(elevated reporting due to lack of sample) 26 10-30'feet at 5-foot'intervals , M Below detection Timits 30 10-20 feet at 5-f6ot intervals Below detection limits 31 10-I5 feet at 5-footintervals Below detection limits 35 10-30 feet at 5-foot intervals Below detection limits t The lower detection limit for TPH when tested in accordance 'with TXl'005 'is 50 mg/kg-and this test method primarily tests for certain carbon compound weights most associated with gasolines, diesels and certain, lubricating oils. One milligram per kilogram (mg Kg) is equivalent to one part per million (ppm). The Contractor is being supplied the above TPl results for information ;purposes. Th'e same limitations that are spec if ed for the geotechnicalreports in t­h_,_,­,,­., cal _... ,_.. -. `Provisions, pages SP-3 and SP-4, paragraph SP-6 apply to these TPH results. 18. Are half-siie, or half-scale, plan sets available? Ans. No. Half scale plans were not produced during design. 19. Are potential bidders, suppliers andsulicontractors required to purchase a set of plans? Ans. No. Plans and specifications are available for review without charge at the City of Lubbock (City Hall,'Purchasing'Department) and atParkhill Smith"and Cooper, lnc., 42,2-2,-8,5 Ih Street, Lubbock, Texas. Other plan sets were sent to theDodge Plan Room, Lubbock, Texas; the AGC i Page 5 of 60� r ITB #001701/VK, Addendum #1 Plan Rooms in Amarillo, Texas; Austin, Texas; El Paso, Texas; Houston, Texas; Lubbock, Texas; and the AGC Plan Room located at Construction Market-Data, 11101 Stemmons Freeway, Suite 101, Dallas, Texas. It is not known whether those plan rooms charge a fee for persons reviewing plans. 20. Is it required to bid all three types of pipe that are allowed in Bid#01-001/vk? Ans. No. The bidder may select one type of pipe upon which to base his bid for each storm sewer line shown on the bid form. The basis-of the bid must be one of the allowable types of pipe for each particular storm sewer line listed on sheet G13 of the drawings and listed on the bid form. After award of a construction contract, then the Contractor must submit a laying schedule of pipe materials in accordance with specification Section 02631. The Contractor's attention is called to the footnotes on drawing sheet G 13 that cast-in-place non-reinforced concrete pipe (CIPNRCP) is not allowable where tunneling or boring installation is required within a storm sewer line that might otherwise allow CIPNRCP. In such cases, a transition to RCP or CCFRP will be necessary. See paragraph 15 above for transition requirements between different types of pipe materials. 21. Section 01020 refers to patterned concrete requirement on certain structures, however there is no information on the plans. Ans. The structures and surfaces that require colored concrete, form liner patterned concrete finishes and stamped pattern concrete finishes are indicated on the detail drawings. Section 03300 of the _ specifications, page 03300-2 indicates the form liner pattern. Section 03300 of the specifications, page 03300-9 indicates the stamped pattern finish. 22. Are the concrete colors specified? Ans. No. Specification Section 03300, page 03300-1, paragraph 1.3.E calls for test panels and samples of colored concrete as specified. Specification Section 03300, page 03300-5, paragraph 3.1 specifies that colored concrete test panels are to be prepared by the Contractor and that colors are contingent on the coloration of the rock riprap. Expensive dyed concrete, such as that required for bright blue, bright yellow or bright green coloration (sometimes referred as "chromic" colors because of the dyes and pigments required) are not expected. Since the final product is to blend with the stone coloration and the surrounding setting of each structure, earth tones are the expected colors (off-white, tan, brown, red, etc.). 23. Does the City have a specific site for excess spoil material? Ans. The handling of salvaged material, waste material and excess soil materials are covered in specification Section 01576. 24. Can/should hazardous materials go to the landfill? Does the City of Lubbock have alandfill? Can the materials be taken there? Ans. These items are addressed in the specifications, Section 01576 and Section 02111. The City of Lubbock does have a landfill Iocated west of Abernathy, Texas. Abernathy, Texas is located north of Lubbock, Texas. The facility is known as the West Texas Region Disposal Facility. Certain petroleum-contaminated soils can be taken to the landfill.-The limits-of,contamination . for landfill disposal shall be in accordance with a Texas Department of Health letter dated February 4, 1991 and a TDH addendum to that letter. The February 4, 1991 TDH letter and letter addendum are attached and are hereby incorporated by reference. Page 6 of 60 E ITB #001-01/VK, Addendum #1 ., 25. There is a im_itation'on open trench length. With respect to cast -in-place concrete pipe, the Contractor may need more than 200 linear feet of trench left open to allow proper set-up and curing. in those cases, will more than 200 linear feet of open trench be allowable? Ans. With respect tocast-in=placeconcrete pipe only, this wi(1 have tobe balanced against local neighborhood conditions and lir hafions on the plans for driveway closures. If the Contractor ` has steel plates that can span the trench width at the ground surface, and the steel plates cannot be easily displaced by automobiles or pickups, then the length of trench open at any one time ' may be adjusted with City concurrence. It is unlikely, however, that more than600 linear feet in short block areas(approximately 300=330 feet between intersections) will be allowed to remain open` -at one time, nor more than one intersection affected at one time. In long block areas (apen int o Cm with only one ely ct0ed a intersection aff a time, maet ybe extended 600 linear fe trench upon concurrence. Steel plates that span the trench width may remain in place for a maximum of 72 hours at any one point. The contractor is responsible for maintaining any steel plates used on the project in good condition at all times. 26. Regarding the seismic monitoring requirements within 75 feet of vibration sources, what if there are several vibration sources that would be greater than 75 feet apart. Will each source be required to be monitored? . Ans. Seismic monitoring is required for the protection of the City of Lubbock and the Contractor. `For sources greater than 75 feet apart," that would depend on the type of source at each location. As an example for clarifying type of source, assume that a trackhoe is excavating virgin material for a trench while the same trench is being backfilled 200 feet away. The trackhoe excavating virgin material would be monitored. The e4uipmenfilik is backfilling the'same'trench 200 feet away would not he monitored unless vibratory compaction equipment is used (hand rammers and hand tampers excluded). Vibratory -inducing equipment such as Bomags and shock inducing equipment such as jack/air Dammers (hand-held jackhammers excluded) will require'monitoring. Consolidation of'cement-stabilized?backfill with hand-held4concrete vibrators does not require seismic monitoring. Trenchless excavating methods will require monitoring. Paving equipment for repairing pavements, such as non -vibrating laydown machines and non -vibrating steel - wheeled rollers, will not require monitoring unless there is vibration -inducing equipment in use. In summary, if initial excavation is being performed or vibration -inducing equipment is being used that can affectan area larger than the point of use, then seisnic nitoingisrequiied.' 27. Is seismic monitoring not required at the locations of the inlet and outlet structures? Ans. 'The initial answer at the pre-bid conference was ``These are generally considered remote locations where the proposed inlet and outlet structures are more than 75 feet away from existing structures." Upon further consideration and evaluation, the following requirements are established: a.The location of Outlet A fat the canyon is sufficiently remote that seismic monitoring will not be required at that location. b. At Clapp Park (Lake 21); the locations of'Inlet Aland Outlet A2 are sufficiently remote that seismic monitoring will not be required once the distance from the nearest existing -: _ structure is greater than 75 feet. j Page 7 of'6tl" �"�`� ',..... ITB #001-01/VK, Addendum #1 lam^ c. At Ribble Park (Lake 20), the location of Inlet B is sufficiently remote that seismic monitoring will not required once the distance from the nearest existing structure is greater than 75 feet. d. Seismic monitoring will be required at Inlet D at the K -Mart Lake (Lake 19N). The monitoring shall include the setting of the cofferdam. Seismic monitoring for removal of the cofferdam will not be required unless equipment is used that induces vibration in the sheet piling to ease the piling's removal. Excavation of materials from within the cofferdam, construction of the inlet structure, backfilling of the structure, rock riprap placement, and final grading will not require monitoring. e. At Leftwich Park (Lake 22), the location of Inlet C is sufficiently remote that seismic monitoring will not be required once the distance from the nearest existing structure is greater than 75 feet. f. Seismic monitoring will be required at the Trinity Lake and Sundial Village Lake (Lake 23N and Lake 23S) for both inlets (Inlets A2 and A3) and outlets (Outlet A3 and Outlet A4). The monitoring shall include the setting of the cofferdams. Seismic monitoring for removal of the cofferdams will not be required unless equipment is used that induces vibration in the sheet piling to ease the piling's removal. Excavation of materials from within the cofferdams, construction of the inlet and outlet structures, backfilling of the structures, rock riprap placement, and final grading will not require monitoring. g. ` At Miller Park (Lake 24), the locations of the inlet and outlet structures are sufficiently remote that seismic monitoring will not be required once the distance from the nearest existing structure is greater than 75 feet. h. Seismic monitoring will be required at Andrews Park (Lake 25) for Inlet A5, Outlet A513 and Outlet A6. The monitoring shall include the setting and removal of the cofferdams regardless of the removal method. Excavation of materials from within the cofferdams, construction of the inlet and outlet structures, backfilling of the structures, rock riprap placement, and final grading will not require monitoring. i. At Leroy Elmore Park (Lake 26), the locations of the inlet and outlet structures are sufficiently remote that seismic monitoring will not be required once the distance from the nearest existing structure is greater than 75 feet. j. At Dupree Park (Lake 27), the locations of the inlet and outlet structures are sufficiently remote that seismic monitoring will not be required once the distance from the nearest existing structure is greater than 75 feet. k. At Buster Long Park (Lake 31), seismic monitoring at Inlet A-8 will be required. The monitoring shall include the setting of the cofferdam. Seismic monitoring for removal of the cofferdam will not be required unless equipment is used that induces vibration in the sheet piling to ease the piling's removal. Excavation of materials from within the cofferdam, construction ofthe inlet, backfilling of the inlet, rock riprap placement, and final grading will not require monitoring. 1. At Buster Long Park (Lake 31), the location of Outlet A-9 is sufficiently remote that seismic monitoring will not be required once the distance from the nearest existing structure is greater than 75 feet.. m. Seismic monitoring at McAlister Park (Lake 37) is not required as long as the distance to the nearest existing building is at least 75 feet. Page 8 of 60 No Text ITB #001=01/VK, Addendum 41 basis, then a pump and water -loading rack shall not be installed. Also, once the work at a particular lake area is complete, then the dewatering pump and water -loading rack must be removed. Any water -loading rack must be located adjacent to the curb at the adjacent street so that water -hauling equipment does not consistently traffic into the park itself The Contractor also has the option of drilling temporary wells on the City of Lubbock property east of Guava Avenue and in McAlister Park west of Frankford Avenue. The drilling of such wells, the casing :and screens, filter pack, pumps, motors and power source shall be the responsibility of the Contractor. Once the construction of the project is completed, the temporary wells shall be - closed in accordance with State of Texas and High`Plains Underground Water Conservation District rules and regulations. The installation and closure of such wells, as well as any water use from dewatering operations, shall be considered as subsidiary to the various bid items. 32. On sheet P21 of the plans, there is a 72 -inch diameter pipe proposed approximately 35 feet deep within 15 feet of a sheet metal building.How can this be installed by open cut? Ans. On sheet P21 of the plans, proposed Line Al -23, make the following revision: "No surface access Station 213+25 to Station.215+00. Boring and jacking or tunneling required.,, 33. At Andrews Park there is,a pipe proposed for installation in a tributary that runs parallel to Memphis Avenue. There is no cofferdam indicated for "this pipe installation. Can the Contractor cofferdam the entire tributary? Ans. The tributary in question is shown on sheet P46.and involves Inlet A5, proposed Line A5B-01 and Outlet A-513. The entire tributary parallel to Memphis Avenue may be isolated by a - cofferdam. At least a 90 -foot length of the cofferdam, if the cofferdam length is greater than 90 feet, shall not be greater than 3225.0 top elevation. The remainder of the cofferdam shall not exceed a top elevation of 3227.0. If the cofferdam length is less than 90 feet, then the entire top of cofferdam must not exceed a top elevation of 3225.0: The overflow point for Andrews Park Lake is located in this tributary. The overflow will not be allowed to be obstructed during construction. 34. Can the lake surface water levels be reduced to a lower elevation? Ans. The lake surface water levels can be reduced to the elevation shown at each lake on the drawings as the "post-project"water surface elevation. 35. Regarding the cofferdams, what if the Contractor needs more than what is shown? The bid is lump sum for cofferdams. How should it be handled in the bids? Ans. The cofferdam limits shown in the plans are schematic in nature.' The bid will be considered to cover whatever cofferdam quantities are necessary for the prosecution of the work. The layouts of the cofferdams are flexible. Itis expected that the Contractor's bid will be for the cofferdam configuration that the Contractor expects will be needed. On drawing sheets GRI through GR21, delete note number 9 under the General Notes on each sheet, and replace with the following: "9. The Contractor is permitted to adjust the layout and location of the sheet pile cofferdam to accommodate construction operations. The Contractor shall submit his proposed layout in accordance with Specification Section 01330. The Owner may require changes to the Contractor's proposed cofferdam layout to"prevent loss of lake storage at flood stage, prevent unacceptable backwater or lake level effects, maintain lake overflow capaci6�. minimize effects"on utilities, minimize effects on park areas, and maintain conveyance through existing channels. The cofferdam layout shown is schematic in nature and"the Contractor's bid shall Page 10 of 60 i No Text ITB #001-01/VK, Addendum #1 backfill thickness. Under the General Instructions to Bidders, page 5, paragraph 16, the Contractor is to guarantee against defects in workmanship and materials for a period of one year. Therefore, the Contractor can elect to perform trench backfill density testing at a greater frequency to avoid trench settlement repairs within the one-year guarantee period. 42. Who will provide construction layout? Will the City of Lubbock provide control? Ans. The data for"horizontal and vertical control are included in the plans. The Contractor is responsible for layout and preparing his own staking and cut sheets. This is in accordance with the General Conditions of the Agreement, page 2 paragraph 10 and the Special Provisions, page SP -1, paragraphs SP -1 and SP -2. 43. Where are the data for the LPST sites? Ans. The data is at the local TNRCC District 2 Field Office, 4630 50h Street, Suite 602, Lubbock, Texas 79414, phone (806) 796-7092. The LPST site numbers are listed on sheet G 11 of the plans. 44. What are the insurance limits for the railroad? Ans. The City of Lubbock has already purchased the Railroad Protective Liability Policy, therefore the _ A -Contractor is not required to purchase this policy. Other insurance requirements are listed in the General Conditions of the Agreement. 45. Locations and rates for Lubbock potable water for construction? Ans. The City of Lubbock Water Utilities Department charges $35.00 'rent on each construction meter. There is also a charge ofS1.85 per 1,000 gallons of water used. The Contractor wilt also be required to have and use a dual backflow preventer when connecting to City fire hydrants. 46. Corps of Engineers permits. What is the schedule for the "permits and are the permits and permit terms required at all lakes? Ans. Recent court rulings have clouded this issue. The bidder shall bid the project as shown on the plans and in accordance with the specifications and this addendum. If, after award'of a contract, the Corps of Engineers issues a permit that, in the opinion of the Engineer, substantially changes the items of wo"rk, then the Owner will enter into negotiations with the Contractor for compensatory adjustments to the construction contract to account for those changes. At this time we expect no changes to be made by the Corps of Engineers. 47. What is the schedule for the award of the contract? Ans. The bid opening is scheduled for 3:00 o'clock p.m., April 25, 2001. It is expected that the award of the contract will be made at the City Council meeting on May 24, 2001. 48. How will the bids be evaluated? Ans. The bid will be awarded to the lowest responsible, responsive Bidder. The Bidder's"attention is directed to the Notice to Bidders wherein the Owner has the right to reject any or all bids or _ waive any formalities. As for the evaluation of the bids, as indicated on the bid form, the City " reserves the right to accept the Total Base Bid and`Base Bid Options in any order or combination that best serves its interest. 49. What will the evaluation criteria be? Ans. The bids will be evaluated and the contract awarded to the lowest responsible Bidder. The City reserves the right to accept the Total Base Bid and Project Options in any order or combination that serves its best interests. The low bid shall be determined on the price combination of the Page 12 of 60 No Text ITB #001-01/VK; Addendum #1 Ans. Contractors can access that area east of Guava Ave. by going to the gate of the City of Lubbock's Water Reclamation Plant located at the north end ofthe project area and asking for the Industrial Waste Pretreatment Team Member. Tell them you are there to look at the storm sewer project and they will gladly open the inside gate for access. 59. Will the Bidder have access to the Farmers Coop Compress area prior to the time for submission of bids? Ans. Access requests will be evaluated on a case-by-case basis. Permission is contingent on the Bidder's reason for access. Test holes and test trenches planned by the Bidder shall be limited to City property east and west of the Farmers Coop Compress Property. All requests for access must be through the City of Lubbock. 60. Can bids be submitted in electronic format? Ans. No. State law, prohibits cities from receiving bids in electronic format where such bids exceed $15,000.00. 61. The proposed storm sewer route on East 46`h Street is close to the south curb line of that street. Will the utility poles south of the south curb line be moved? Ans. The segment of proposed storm sewer in question is Line Ai -12 in East 46t11 Street, from Station 109+90.99 to Station 132+66.89, plan -profile sheet numbers PI 1 P12 and P13. The utility poles on the south side of the street are not planned for relocation or removal. The Owner will permit the Contractor to shift the alignment of Line Al -12 northward toward the center of East 46'h Street, where the street is curbed, however the Contractor should be aware that there is an existing sanitary sewer close to the center of East 46'h Street as shown on plan -profile sheets P12 and P13. That sanitary sewer is not planned for relocation or removal. 62. Is direct jack installation (single pass method) of a RCP or CCFRP an acceptable alternative to liner plate installation (two pass method) where liner plate is specified if the direct jack pipe is capable of bearing the external loads without help of the liner plate? Ans. See paragraph 36 above. 63. At locations where liner plate is specified, details read "96 -inch diameter minimum tunnel liner plate if open or shielded face tunneling is used". Is this statement meant to exclude the use of ribs and lagging? Is this statement suggesting that if micro -tunneling is used, the pipe may be direct jacked? Ans. See paragraph 36 above. 64. Are steel ribs and wood lagging allowed as a primary tunnel liner at any locations, including ones where steel liner plate is detailed? Ans. Steel ribs and wood lagging will be allowed as a 11 rimary tunnel lining at any location except where steel casing is specified. Rib and lagging tunnels are considered temporary construction items and as such shall be designed by the Contractor to withstand the anticipated loads with the tunneling industry recommended factor of safety. The design shall be sealed by licensed professional engineer and four copies of the design submitted to the Engineer for record purposes in accordancewith specification Section 01330 and Section 02425. All of specification Section 02425 shall apply to rib and lagging tunnels except that the specification paragraphs pertaining to steel liner plate shall not apply. All of specification Section 02430 pertaining to tunnel grout and grouting shall apply to rib and lagging tunnels. In addition, the pipe laying schedule shall indicate by stations where rib and lagging tunnels are planned. Steel rib and wood lagging tunnels shall also meet the following requirements: Page 14 of 60 No Text ITB #001-01/VK, Addendum #1 bid signed by an official or duly authorized agent.

General Conditions of the Agreement, Partial Payments, Paragraph 42, Page 15 Add the following to the General Conditions of the Agreement, Partial Payments, Paragraph 42: ' "Partial payments requested by the Contractor may include materials delivered, but not yet incorporated into the project. If payment is requested on the basis of materials and equipment not incorporated in the work but delivered and suitably stored at the site, or at another location agreed to in writing, then the application for payment shall also be accompanied by a bill of sale or invoice warranting that the equipment and materials are free and clear of all liens and evidence that the materials and equipment are covered by the appropriate property insurance and other arrangements to protect the Owner's interest therein. Materials and equipment shall not be considered for partial payment if stored where the Owner can not confirm the quantities or otherwise seize and secure the equipment and materials in the event that the Contractor defaults on the work. Materials and _ equipment that are eligible for partial payment will be carried as "Materials on Hand" on the partial pay estimates and then moved from "Materials on Hand" to completed items of the work once those materials and equipment are incorporated into the work. Partial payments for completed items of work will reflect adjustments for prior partial payments made to the Contractor, for the same completed items of work, for "Materials on Hand". Partial payments for "Materials on Hand shall be subject to the five -percent retainage.

The fact that the specifications may fail to be sufficiently complete in some detail will not relieve the Contractor of full responsibility for providing materials of high quality and for protecting them adequately until incorporated into the project.

The City of Lubbock agrees that it will furnish Contractor the location of all such underground lines and utilities of which it has knowledge.

Such notice, however, shall not relieve the Contractor of responsibility for any damage resulting from his blasting operations. 23 CONTRACTOR'S REPRESENTATIVE The successful bidder shall be required to have a responsible local representative available at all times while the work is in progress under this contract. The successful bidder shall be required to furnish the name, address and telephone number where such local representative may be reached during the time that the work contemplated by this contract is in progress. 24 INSURANCE 24.1 The Contractor shall not commence work under this contract until he has obtained all insurance as required in the General Conditions of the contract documents, from an underwriter authorized to do business in the State of Texas and satisfactory to the City.

The bidders' attention is further directed to the requirements of Article 5159a, Vernon's Annotated Civil Statutes providing for the payment of the wage schedules above mentioned and the bidder's obligations thereunder. The inclusion of the schedule of general prevailing rate of per diem wages in these contract documents does not release the Contractor from compliance with any wage law that may be applicable.

Notes: TEST CRITERIA TABLES Exfiltration and Infiltration Water Tests: Refer to Table 02533-1, Water Test Allowable Leakage, at the end of this Section. Low Pressure Air Test: 1. Times in Table 02533-2, Time Allowed For Pressure Loss From 3.5 psig to 2.5 psig, at the end of this Section, are based on the equation: T = 0.0850(D)(K)/(Q) where: T = time for pressure to drop 1.0 pounds per square inch gauge in seconds K = 0.000419 DL, but not less than 1.0 D = average inside diameter in inches L = length of line of same pipe size in feet Q = rate of loss, 0.0015 ft'/min./sq. ft. internal surface 2. Since a K value of less than 1.0 shall not be used, there are minimum testing times for each pipe diameter as given in Table 02533-3, Minimum Testing Times for Low Pressure Air Test. 1. When two sizes of pipe are involved, the time shall be computed by the ratio of lengths involved. 2. Lines with a 48 -inch average inside diameter and larger shall be air tested at each j oint. 01257198 ACCEPTANCE TESTING FOR STORM SEWERS 02533-5 01/01 3. Lines between 36 -inch and 48 -inch diameter may be air -tested at each joint with the Engineer's concurrence. The Contractor must demonstrate that access to the joints and set-up of the test apparatus is feasible and that worker safety is not compromised. -" 4. Lines with an average inside diameter equal to or greater than 48 inches must be air tested for leakage at each joint. 5. If the joint test is used, a visual inspection of the joint shall be performed immediately -° after testing. 6. For joint test, the pipe is to be pressurized to 3.5 psi greater than the pressure exerted by groundwater above the pipe. Once the pressure has stabilized, the minimum times allowable for the pressure to drop from 3.5 pounds per square inch gauge to 2.5 pounds per square inch gauge shall be 10 seconds. 3.5 LEAKAGE TESTING FOR MANHOLES A. Perform vacuum test as specified by Cherne Industries, Inc. in accordance with ASTM C 1244. This test applies to all manholes within a watertight designated run of pipe, end manholes inclusive as applicable, as shown on the drawings. B. After completion on watertight manhole construction, wall sealing, or rehabilitation, but prior to backfilling, test manholes for water tightness using vacuum testing procedures. C. Plug incoming and outgoing lines with suitably -sized pneumatic or mechanical plugs. Ensure plugs are properly rated for pressures required for test; follow manufacturer's safety and installation recommendations. Place plugs a minimum of 6 inches outside of manhole walls. Brace inverts to prevent lines from being dislodged if lines entering manhole have not been backfilled. D. Vacuum testing: 1. Install vacuum tester head assembly at top access point of manhole and adjust for proper seal on straight top section of manhole structure. Following manufacturer's instructions and safety precautions, inflate sealing element to the recommended maximum inflation pressure; do not over -inflate. 2. Evacuate manhole with vacuum pump to 10 inches mercury (Hg), disconnect pump, and monitor vacuum for the time period specified in Table 02533 — 4 at the end of this section.

D. Offsets: Offsets at form laps and horizontal edges shall not exceed the limits given in paragraph 3.4. E. Bearing Plate: Bearing plates, boards, or other supports necessary for two-stage construction shall be removed, and any indentations exceeding 1/z inch left in the concrete from such plates shall be cleaned, moistened, filled with mortar, trowelled, and cured. F. Strength: Unless otherwise designated in the project specifications or on the plans, the strength of the concrete shall be at least 3000 psi, when the concrete is not exposed to severe and frequent freezing and thawing or 4000 psi when the concrete is exposed to severe and frequent freezing and thawing, as determined on the basis of 28 day compressive strength tests. Strengths shall be considered satisfactory if the average of any five consecutive sets of strength tests of the laboratory -cured specimens is equal to or greater than the specified strength, and if not more than 20 percent of the strength tests have values less than the specified strength by more than 200 psi. The pipe represented by unsatisfactory strength tests on cylinders shall be further tested either by coring or by load testing at the Contractor's option.

Internal Pressure: The completed and cured pipe shall be capable of withstanding an intermittent internal hydrostatic head of 15 feet, as measured from the center line of the pipe, without structural failure. PART 3 - EXECUTION 3.1 EXCAVATION A. The trench shall be excavated to the lines and grades shown on the drawings. The bottom of the trench shall be prepared to provide full, firm, uniform support by undisturbed earth or compacted fill B. The flow line grade of the finished pipe shall not vary more than 0.10 foot from the grade shown on the drawings between adjacent manholes. 3.2 PLACEMENT ,. A. Placing Concrete: All surfaces against which concrete is to be placed shall be free from standing water, mud, and debris, and shall be firm enough to prevent contamination of the concrete by earth or other foreign material. Absorptive surfaces against which concrete is to be placed shall be moistened thoroughly so that the moisture will not be drawn from the freshly -placed concrete. B. The fresh concrete shall be consolidated effectively at production speeds, over the entire circumference and from within the pipe shell. Consolidation methods shall be capable of building up sufficient pressure to bond the concrete effectively to the surrounding earth. Evidence of this pressure shall always be visible as the pipe is being extruded. C. The cast -in-place concrete pipe shall be constructed in one placement with aluminum forms. The concrete shall be placed around the full circumference of the pipe, with the invert of the pipe available for inspection at all times during the pouring operation. z,+ D. The temperature of concrete when it is being placed shall not be (1) more than 90 degrees F, (2) less than 40 degrees in moderate weather, nor (3) less than 50 degrees when the mean daily temperature in the vicinity of the work site falls below 40 degrees. Whenever the mean daily temperature in the vicinity of the work site falls below 40 degrees F for more than one day, the concrete shall be maintained at a temperature not lower than 50 degrees for at least 72 hours of protection at 50 degrees F. Where artificial heat is employed, special care shall be taken to prevent the concrete from drying. If concrete is placed when the weather is such that the temperature of the concrete would exceed 90 degrees F, the Contractor shall employ effective means — such as precooling of aggregates and mixing water or placing at night — as necessary to maintain the temperature of the concrete, as it is placed, below 90 degrees F. 3.3 CONSTRUCTION JOINTS A. Construction joints may be formed by either of the two following methods: 1. The joint shall be formed at about 45 degrees from the vertical. After cleaning, wetting, and freeing all such joints of all laitance, loose or defective concrete, coatings and foreign material shall be removed to assure a good bond. 2. After squaring off the end of the pipe, an excavation shall be performed along the sides and bottom of the joint of such size as to permit the placing of a concrete collar around the outside of the joint. This collar shall have a minimum thickness at the joint of 1 1/a 01257198 CAST -IN-PLACE NON -REINFORCED CONCRETE PIPE 03301 -5 g-,, 01/01 times the wall thickness of the pipe and shall lap the joint by at least 2 times the wall thickness. 3. Concrete epoxy bonding agents shall be used when, in the opinion of the Engineer, the epoxy is needed to form an acceptable bond between the collar and the joint. 3.4 FINISH A. Except for the form offsets, the interior surface of the pipe shall be equivalent to or better than a wood float finish. B. Variations in the internal diameter shall not exceed 1/32 inch per diameter inch. (Example: for 24 inch pipe, 1/32 x 24 inches = 3/a inch variation). Offsets at form laps and horizontal edges shall not exceed the limits specified in the following table: -- Pipe Diameter Maximum Offset - 24" 3/8„ 27" 3/8" - 30" 3/8" 36" 1/2" 42" 1/2" 48" 5/8" 54" 5/8" 60" 5/8" 66" 5/8" — 72" 3/4" 78" 3/4" C. All extraneous concrete shall be removed from the interior surface as soon as possible after placing. Any additional finish work or repair work required to be done on the pipe shall be F— completed within 5 days after the pipe is placed. D. The finished surface of the concrete pipe shall be substantially free of fractures, cracks, and interior surface roughness. If obvious segregation or honeycombing, or inadequate wall -- thickness, are encountered during inspection, the pipe may be rejected by the Engineer. E. Shrinkage cracks shall be filled with non -shrink grout. 3.5 CURING A. Immediately after finishing exposed exterior surfaces, the curing of these surfaces shall be -_ undertaken by any one or a combination of the following methods: 1. Pigmented sealing compound, blanketing, cotton mat, polyethylene film or spraying methods as specified in ASTM C 309 and ASTM C 171.x, 2. A 3 -inch layer of moist earth may be backfilled over the pipe. However, care must be taken to avoid damage to the fresh concrete while placing the backfill. The thickness of the backfill shall be increased to 6 inches after initial set of the concrete has occurred. 01257198 CAST -IN-PLACE NON -REINFORCED CONCRETE PIPE 03301 6 01/01 �-. This backfill shall be kept moist for not less than 7 days, or until pipe is covered with 12 inches of soil, whichever is greater. B. The exposed top portion of the pipe may be covered with wet burlap or other material of high moisture retentive properties immediately after the pipe is cast. The covering material shall be kept continuously moist until the placement of final backfill as described under Section A. Moisture retentive material may be removed or left in place at the option of the Contractor. C. A pigmented membrane -curing compound conforming to ASTM C 309 may be applied to the exposed top surface immediately after the pipe is cast. The compound shall be applied at the rate of not less than 1 gal. for each 150 ft' of exposed concrete. The pipe shall then be covered with a minimum of 3 inches of moist loose soil when the curing compound is sufficiently hard to resist damage from the fill. Final backfill shall be placed as soon as the pipe attains suitable strength. D. Polyethylene film complying with ASTM C 171, nominal thickness 0.0015 inches may be placed on the exposed top surface of the pipe immediately after the pipe is cast. The film shall be anchored in place with loose soil to assure continuous, adequate curing. The trench shall be completely backfilled as soon as the pipe attains suitable strength. E. A humid atmosphere within the pipe as evidenced by condensation on the interior surface shall be maintained for at least 7 days following placement except for a maximum period of 48 hours allowed for removing forms and making repairs. To prevent air drafts which may dry the pipe and to maintain a humid atmosphere inside the pipe, all openings into the pipeline shall be kept closed or covered except when and where work is actually in progress on the inside of the pipe. If necessary to promote high humidity, the pipeline shall be partially filled with ponded water during the curing period. 3.6 TESTING A. Secure at least one sample in accordance with ASTM C 172 for each 50 cubic yards of concrete used, but not less than one sample for each day's work, nor less than one sample for each section of pipe placed in a continuous operation. B. Mold and cure two cylinders from each sample in accordance with ASTM C 31. C. Test the two specimens at 28 days of curing in accordance with ASTM C 39. The 28 -day test result shall be the average of the strength of the two specimens, except that if one specimen in a test manifests evidence of improper sampling, molding, or testing, it shall be discarded and the strength of the remaining specimen used. D. Determine slump and air content of concrete in accordance with ASTM Test Methods C 143 (slump) and C 231, C 173, C 138 (air content). Tests shall be performed no less frequently than the sampling frequency required by that said in paragraph 3.6.A. E. If the load carrying capability of the pipe is in question, the Engineer may require load testing in accordance with ACI -346. Such test shall be the expense of the Contractor. F. Thickness Test - The Contractor shall measure the thickness of the pipe at least every 200 lineal ft. with individual measurements staggered at points designated by the Engineer. Where thickness is not determined by probes through the fresh concrete, small holes shall be drilled for the purpose. The Contractor shall patch all core holes in a manner that will be permanent and will not leak. Furnish the Engineer with logs of thickness measurements. G. Hydrostatic Test: In sections of the storm sewer marked "watertight" in the drawings, hydrostatic tests shall be performed in accordance with ACI 346. The test shall be made at any time after the concrete has been allowed to harden for 28 days, or earlier if mutually agreed upon. The pipeline shall be filled with water to the head specified in Section 02533, "Acceptance Testing for Storm Sewers" and kept filled at least 48 hours. The line may be 01257198 CAST -IN-PLACE NON -REINFORCED CONCRETE PIPE 03301-7 01/01 filled in one length or between structures or bulkheads. If leaks are evident, the line shall be drained and the leaks repaired by, and at the expense of, the Contractor. Thereafter, with the line filled and under the specified head, there shall be a test for a minimum of 4 hours during which loss of water from the section under test shall be measured. Water less than 50° F in temperature shall not be used for this test. During the test period, the exfiltration rate shall not exceed 1000 gallons per inch of diameter per mile per 24 hours. If the line fails the hydrostatic test, the Contractor shall drain the line, repair imperfections as necessary to provide continuity in structural and hydraulic integrity and retest the line as described above. 3.7 BACKFILL A. Refer to Section 02317 - Excavation and Backfill for Utilities and Section 02320 - Utility TM Backfill Materials. B. Depth of backfill over the top of cast -in-place concrete pipe shall not exceed 6 inches until the pipe has been in place at least 24 hours. Loose backfill may then be completed after the pipe has been in place 24 hours. The backfill shall be materially free of clods or rocks having a diameter greater than 2 inches, roots, or other deleterious foreign material. Until the height of the backfill exceeds 3 feet, machine -placed backfill shall not be allowed to "free -fall" more than three feet. The Contractor will be responsible for any damage to the pipe caused by backfilling operations. Light traffic (axle loads less than 6,000 pounds) may be routed over the pipe 48 hours after the pipe has been in place. Unrestricted traffic may be permitted over the pipe after the pipe has been in place at least 72 hours. Where backfill is to be applied mechanically, concrete strength shall reach 2,000 psi before compacting.
