Whenever in the Specifications or drawings accompanying this agreement, the terms of description of various qualities relative to finish, workmanship, or other qualities of similar kind which cannot, from their na- ture, be specifically and clearly described and specified, but are necessarily described in general terms, the fulfillment of which must depend on individual judgment, then, in all such cases, any question of the fulfillment of said Specifications shall be decided by the Owner's Representative, and said work shall be done in accordance with his interpretations of the meaning of the words, terms, or clauses defining the character of the work. b.

No verbal agreement or conversation with any officer, agent, or employee of the owner, either before or after the execution of this contract, shall effect or modify any of the terms or obligations herein contained. 18. CHARACTER OF WORKMEN The Contractor agrees to employ only orderly and competent men, skillful in the performance in the type of work required under this contract, to do the work; and agrees that whenever the Owner's Representative shall inform him in writing that any man or men on the work, are, in his opinion, incompetent, unfaithful, or dis- , orderly, such man or men shal€ be discharged from the work and shall not again be employed on the work with- out the Owner's Representative's written consent. 19. CONSTRUCTION PLANT The Contractor shall provide all labor, tools, equipment, machinery and materials necessary in the prosecu- tion and completion of this contract where it is not otherwise specifically provided that Owner shall fur- nish same, and it is also understood that Owner shall not be held responsible for the care, preservation, conservation, or protection of any materials, tools, equipment or machinery or any part of the work until it is finally completed and accepted. 3 The building of structures for the housing of men or equipment will be permitted only at such places as the Owner's Representative shall direct, and the sanitary conditions of the grounds in or about such structure shall at all times be maintained in a manner satisfactory to the Owner's Representative. 20. SANITATION Necessary sanitary conveniences for the use of laborers on the work site, properly secluded from public ob- servation, shall be constructed and maintained by the Contractor in such manner and at such points as shall be approved by the owner's Representative and their use shall be strictly enforced. �s -27- F ".a 21. OBSERVATION AND TESTING the Owner or Owner's Representative shall have the right at all reasonable times to observe and test the t work. Contractor shall make necessary arrangements and provide proper facilities and access for such obser- vation and testing at any location wherever work is in preparation or progress. Contractor shall ascertain the scope of any observation which may be contemplated by Owner or Owner's Representative and shall give am- ple notice as to the time each part of the work will be ready for such observation. Owner or Owner's Rep- resentative may reject any work found to be defective or not in accordance with the contract documents, re- gardless of the stage of its completion or the time or place of discovery of such errors and regardless of whether Owner's Observer has previously accepted the work through oversight or otherwise. If any work should be covered without approval or consent of the Owner, it must, if requested by Owner or Owner's Repre- sentative, be uncovered for examination at Contractor's expense. In the event that any part of the work is being fabricated or manufactured at a location where it is not convenient for Owner or Owner's Representa- tive to make observations of such work or require testing of said work, then in such event Owner or Owner's Representative may require Contractor to furnish owner or Owner's Representative certificates of inspection, testing or approval made by persons competent to perform such tasks at the location where that part of the work is being manufactured or fabricated. All such tests will be in accordance with the methods prescribed by the American Society for Testing and Materials or such other applicable organization as may be required by law or the contract documents. If any work which is required to be inspected, tested, or approved is covered up without written approval or consent of the Owner or Owner's Representative, it must, if requested by the Owner or Owner's Representa- tive, be uncovered for observation and testing at the Contractor's expense. The cost of all such inspec- tions, tests and approvals shall be borne by the Contractor unless otherwise provided herein. Any work which fails to meet the requirements of any such tests, inspections or approval, and any work which meets the requirements of any such tests or approval but does not meet the requirements of the contract documents shall be considered defective. such defective work shall be corrected at the Contractor's expense. Neither observations by the Owner or Owner's Representative, nor inspections, tests, or approvals made by Owner, Owner's Representative, or other persons authorized under this agreement to make such inspections, tests, or approvals shall relieve the Contractor from his obligation to perform the work in accordance with the requirements of the contract documents. 22. DEFECTS AND THEIR REMEDIES It is further agreed that if the work or any part thereof, or any material brought on the site of the work for use in the work or selected for the same, shall be deemed by the owner or Owners' Representative as un- suitable or not in conformity with plans, specification and contract documents, the Contractor shall, after receipt of written notice thereof from the Owner's Representative, forthwith remove such material and re- build or otherwise remedy such work so that it shalt be in full accordance with this contract, it is fur- ther agreed that any remedial action contemplated as hereinabove set forth shall be at Contractor's expense. 23. CHANGES AND ALTERATIONS The Contractor further agrees that the Owner may make such changes and alterations as the Owner may see fit, in the line, grade, form dimensions, plans or or materials for the work herein contemplated, or any part thereof, either before or after the beginning of the construction, without affecting the validity of this contract and the accompanying bond. If such changes or alterations diminish the quantity of the work to be done, they shall not constitute the _:_ basis for a claim for damages, or anticipated profits on the work that may be dispensed with, if they in- crease the amount of work, and the increased work can fairly be classified under the specifications, such increase shalt be paid according to the quantity actually done and at the unit price established for such R work under this contract; otherwise such additional work shall be paid for as provided under Extra Work. In 3 -28- case the Owner shall make such changes or alterations as shall make useless any work already done or mate - vial already furnished or used in said work, then the Owner shall recompense the Contractor for any material or labor so used, and for any actual loss occasioned by such change, due to actual expenses incurred in preparation for the work as originally planned. 24. EXTRA WORK The term "extra work" as used in this contract shall be understood to mean and include all work that may be required by the owner or Owner's Representative to be done by the Contractor to accomplish any change, at- teration or addition to the work as shown on the plans and specifications or contract documents and not cov- ered by Contractor's proposal, except as provided under Changes and Alterations herein. It is agreed that the Contractor shall perform all extra work under the direction of the Owner's Representa- tive when presented with a written work order signed by the Owner's Representative; subject, however, to the right of the Contractor to require written confirmation of such extra work order by the Owner. It is also agreed that the compensation to be paid to the Contractor for performing said extra work shalt be determined by the following methods: Method (A) - By agreed unit prices; or Method (B) - By agreed lump sun; or Method (C) - If neither Method (A) or Method (8) be agreed upon before the extra work is com- menced, then the Contractor shall be paid the actual field cost of the work, plus fifteen (15%) per cent. In the event said extra work be performed and paid for under Method (C), then the provisions of this para- graph shall apply and the "actual field cost" is hereby defined to include the cost of all workmen, such as foremen, timekeepers, mechanics and laborers, materials, supplies, teams, trucks, rentals on machinery and equipment, for the time actually employed or used on such extra work, plus actual transportation charges necessarily incurred, together with all expenses incurred directly on account of such extra work, including Social Security, Old Age Benefits, Maintenance Bonds, Public Liability and Property Damage and Workmen's Compensation and all other insurances as may be required by law or ordinances or directed by the owner or Owner's Representative, or by them agreed to. Owner's Representative may direct the form in which accounts of the actual field cost shalt be kept and records of these accounts shall be made available to the owner's Representative. The Owner's Representative may also specify in writing, before the work commences, the method of doing the work and the type and kind of machinery and equipment to be used; otherwise, these mat- ters shall be determined by the Contractor. Unless otherwise agreed upon, the prices for the use of machin- ery and equipment shall be determined by using 100%, unless otherwise specified, of the latest Schedule of Equipment and ownership Expenses adopted by the Associated General Contractors of America. Where practical, the terms and prices for the use of machinery and equipment shalt be incorporated in the written extra work order. The fifteen percent (15%) of the actual field cost to be paid to Contractor shall cover and com- pensate him for his profit, overhead, general superintendence and field office expense, and all other ele- ments of cost and expense not embraced within the actual field cost as herein defined, save that where the Contractor's Camp or Field Office must be maintained primarily on account of such Extra Work, then the cost to maintain and operate the same shall be included in the "actual field cost." No claim for extra work of any kind will be allowed unless ordered in writing by Owner's Representative. In case any orders or instructions appear to the Contractor to involve extra work for which he should receive x compensation or an adjustment in the construction time, he shall make written request to the Owner's Repre- sentative for a written order authorizing such extra work- Should a difference of opinion arise as to what does or does not constitute extra work or as to the payment therefore, and the owner's Representative in- sists upon its performance, the Contractor shall proceed with the work after making written request for written order and shall keep adequate and accurate account of the actual field cost thereof, as provided under Method (C). The Contractor will thereby preserve the right to submit the matter of payment to arbi- tration as herein below provided. LJ 5 25. DISCREPANCIES AND OM1SSi0NS - It is further agreed that it is the intent of this contract that all work described in the proposal, the specifications, plans and other contract documents, is to be done for the prices quoted by the Contractor and that such price shall include all appurtenances necessary to complete the work in accordance with the intent of these contract documents as interpreted by owner's Representative. If the Contractor finds any discrepancies or omissions in these plans, specifications, or contract documents, he should notify the Owners' Representative and obtain a clarification before the bids are received, and if no such request is _,. received by the owner's Representative prior to the opening of bids, then it shall be considered that the .. Contractor fully understands the work to be included and has provided sufficient sums in his proposal to complete the work in accordance with these plans and specifications. It is further understood that any re- quest for clarification must be submitted no later than five days prior to the opening of bids. 26. RIGHT OF OWNER TO MODIFY METHODS AND EQUIPMENT If at any time the methods or equipment used by the Contractor are found to be inadequate to secure the quality of work with the rate of progress required under this contract, the owner or owner's Representative may order the Contractor in writing to increase their safety or improve their character and efficiency and the Contractor shall comply with such order. If, at any time, the working force of the Contractor is inadequate for securing the progress herein speci- fied, the Contractor shall, if so ordered in writing, increase his force or equipment, or both, to such an extent as to give reasonable assurance of compliance with the schedule of progress. 27. .

It is understood and agreed that the actual amount of work to be done and the materials to be furnished under this contract may differ somewhat from these estimates, and that where the basis for payment under this contract is the unit price method, payment shall be for the actual amount of work done and materials furnished on the project. 38. PROTECTION OF ADJOINING PROPERTY The Contractor shall take proper means to protect the adjacent or adjoining property or properties in any way encountered, which may be injured or seriously affected by any process of construction to be undertaken under this agreement, from any damage or injury by reason of said process of construction; and he shall be liable for any and all claims for such damage on account of his failure to fully protect all adjacent property. The Contractor agrees to indemnify, save and hold harmless the Owner against any claim or claims for damages due to any injury to any adjacent or adjoining property, arising or growing out of the perfor- mance of this contract, but such indemnity shalt not apply to any claim of any kind arising out of the exis- tence or character of the work. 39. PRICE FOR FORK In consideration of the furnishing of all necessary labor, equipment and material and the completion of all work by the Contractor, and on the delivery of all materials embraced in this contract in full conformity with the specifications and stipulations herein contained, the Owner agrees to pay the Contractor the price ' set forth in the proposal attached hereto, which has been made a part of this contract, and the Contractor hereby agrees to receive such price in full for furnishing all materials and all labor required for the 1...,. aforesaid work, also, for all expenses incurred by him and for well and truly performing the same and the whole thereof in the manner and according to this agreement, the attached specifications, plans, contract i documents and requirements of Owner's Representative. _ 40. PAYMENTS No payments made or certificates given shall be considered as conclusive evidence of the performance of the contract, either wholly or in part, nor shall any certificate or payment be considered as acceptance of de- fective work. Contractor shall at any time requested during the progress of the work furnish the Owner or Owner's Representative with a verifying certificate showing the Contractor's total outstanding indebtedness in connection with the work. Before final payment is made, Contractor shall satisfy Owner, by affidavit or otherwise, that there are no outstanding liens against Owner's premises by reason of any work under the con- tract. Acceptance by Contractor of final payment of the contract price shall constitute a waiver of all claims against Owner which have not theretofore been timely filed as provided in this contract. -35- 41. PARTIAL PAYMENTS On or before the tenth day of each month, the Contractor shall submit to Owner's Representative an applica- tion for partial payment. Owner's Representative shall review said application for partial payment and the progress of the work made by the Contractor and if found to be in order shall prepare a certificate for par- tial payment showing as completely as practical the total value of the work done by the Contractor up to and including the last day of the preceding month; said statement shall also include the value of all sound ma- terials delivered on site of the work that are to be fabricated into the work. The Owner shall then pay the Contractor on or before the fifteenth day of the current month the total amount of the Owner's Representative's Certificate of Partial Payment, less 5% of the amount thereof, which 5% shall be retained until final payment, and further, less all previous payments and all further sums that may be retained by Owner under the terns; of this agreement. it is understood, however, that in case the whole work be near to completion, and this fact is certified to by Owner's Representative and some unexpected and some unusual delay occurs due to no fault or negligence on the part of the Contractor, the Owner may upon written recommendation of Owner's Representative pay a reasonable and equitable portion of the retained per- centage due Contractor. 42. FINAL COMPLETION AND ACCEPTANCE Within thirty-one (31) days after the Contractor has given the Owner's Representative written notice that the work has been completed or substantially completed, the owner's Representative and the Owner shall in- zspeCt the work and within said time, if the work be found to be completed or substantially completed in ac- cordance with the contract documents, the Owner's Representative shall issue to the Owner and Contractor his certificate of completion, and thereupon it shall be the duty of the Owner within thirty-one (31) days to issue a certificate of acceptance of the work to the Contractor. 43. FINAL PAYMENT Upon the issuance of the certificate of completion, the Owner's Representative shall proceed to make final measurement and prepare a final statement of the value of all work performed and materials furnished under the terms of the agreement, and shall certify same to the owner, who shall pay to the Contractor on or be- fore the 31st day after the date of certificate of completion, the balance due Contractor under the terms of this agreement, provided he has fully performed his contractual obligations under the terms of this con- tract; and said payment shall become due in any event upon said performance by the Contractor. Neither the certificate of acceptance nor the final payment, nor any provisions in the contract documents shall relieve the Contractor of the obligation for fulfillment of any warranty which may be required in the special condi- tions (if any) of this contract or required in the specifications made a part of this contract. 44. CORRECTION OF WORK BEFORE FINAL PAYMENT FOR WORK Contractor shall promptly remove from Owners' premises all materials condemned by the Owner's Representative on account of failure to conform to the contract, whether actually incorporated in the work or not, and Con- tractor shall at his own expense promptly replace such condemned materials with other materials conforming to the requirements of the contract.

If Contractor does not remove and replace any such condemned work within a reasonable time after a written notice by the owner or the Owner's Representative, Owner may remove and replace it at Contractor's expense. 45. CORRECTION OF WORK AFTER FINAL PAYMENT Neither the final payment nor certificate nor any provision in this contract shall relieve the Contractor of responsibility for faulty materials or workmanship, and he shall remedy any defects due thereto and pay for any damage to other work resulting therefrom, which shall appear within a period of one (1) year from the -36- r j i date of substantial completion. The Owner or the Owner's Representative shalt give notice of observed de- fects with reasonable promptness. 46. PAYMENT WITHHELD The Owner may, on account of subsequently discovered evidence, withhold or nullify the whole or part of any certificate to such extent as may be necessary to protect himself from loss on account of: (a) Defective work not remedied. (b) Claims filed or reasonable evidence indicating possible filing of claims. (c) Failure of the Contractor to make payments promptly to subcontractors or for materials or Labor. (d) Damage to another contractor. When the above grounds are removed, or the Contractor provides a surety bond satisfactory to the Owner, which will protect the owner in the amount withheld, payment shall be made for amounts withheld because of them. 47.

After receiving said notice of abandonment, the Contractor shall not remove from the work any machinery, equipment, tools, materials or supplies then on the job, but the same, together with any materials and equipment under the contract for work, may be held for use on the work by the Owner or the Surety of the Contractor, or another contractor, in completion of the work; and the Contractor shall not receive any .. rental or credit therefore (except when used in connection with Extra Work, where credit shall be allowed as provided for under paragraph 24 of this contract); it being understood that the use of such equipment and materials will ultimately reduce the cost to complete the work and be reflected in the final settlement. In case the Surety should fail to commence compliance with the notice for completion hereinbefore provided for within ten (10) days after service of such notice, then the Owner may provide for completion of the work in either of the following elective manners: (a) The Owner may employ such force of men and use of machinery, equipment, tools, materials and sup- plies as said Owner may deem necessary to complete the work and charge the expense of such labor, machinery, equipment, toots, materials and supplies to said Contractor, and the expense so charged shalt be deducted and paid by the Owner out of such moneys as may be due, or that may thereafter at any time become due to the Contractor under and by virtue of this Agreement. In case such expense is less than the sun which would have been payable under this contract, if the same had been com- pleted by the Contractor, then said Contractor shall receive the difference. In case such expense is greater than the sum which would have been payable under this contract, if the same had been com- pleted by said Contractor, then the Contractor and/or his Surety shall pay the amount of such excess to the Owner; or (b) The Owner, under sealed bids, after notice published as required by law, at least twice in a newspa- per having a general circulation in the County of location of the work, may let the contract for the completion of the work under substantially the same terms and conditions which are provided in this contract.

However, should the cost to complete any such new contract prove to be less than that which would have been the cost to complete the work under this contract, the Contractor or his Surety shall be credited therewith. Hr When the work shall have been substantially completed, the Contractor and his Surety shall be so notified and certificates of completion and acceptance, as provided in paragraph 42 hereinabove set forth, shall be 1 issued. A complete itemized statement of the contract accounts, certified to by Owner's Representative as LA being correct shalt then be prepared and delivered to Contractor and his Surety, whereon the Contractor or i his Surety, or the Owner as the case may be, shall pay the balance due as reflected by said statement within 30 days after the date of certificate of completion. -38- In the event the statement of accounts shows that the cost to complete the work is less than that which would have been the cost to the Owner had the work been completed by the Contractor under the terms of this contract, or when the Contractor and/or his Surety shall pay the balance shown to be due by them to the owner, then all machinery, equipment, tools, materials or supplies left on the site of the work shall be turned over to the Contractor and/or his Surety. Should the cost to complete the work exceed the contract price, and the Contractor and/or his Surety fait to pay the amount due the owner within the time designated hereinabove, and there remains any machinery, equipment, toots, materials or supplies on the site of the work, notice thereof, together with an itemized list of such equipment and materials shall be mailed to the Contractor and his Surety at the respective addresses designated in this contract; provided, however, that actual written notice given in any manner will satisfy this condition. After mailing, or other giving of such notice, such property shall be held at the risk of the Contractor and his Surety subject only to the duty of the owner to exercise ordinary care to protect such property. After fifteen (15) days from the date of said notice the Owner may sell such machinery, equipment, tools, materials or supplies and apply the net sum derived from such sale to the credit of the Contractor and his Surety. Such sale may be made at either public or private sale, with or without notice, as the Owner may elect. The Owner shall release any machin- ery, equipment, tools, materials, or supplies which remain on the *jobsite and belong to persons other than the Contractor or his Surety, to their proper owners. 50. ABANDONMENT BY OWNER In case the Owner shall fail to comply with the terms of this contract, and should fail or refuse to comply with said terms within ten (10) days after written notification by the Contractor, then the Contractor may suspend or wholly abandon the work, and may remove therefrom all machinery, toots, and equipment, and all materials on the ground that have not been included in payments to the Contractor and have not been incorpo- rated into the work. Thereupon, the Owner's Representative shalt make an estimate of the total amount earned by the Contractor, which estimate shall include the value of all work actually completed by said Con- tractor at the prices stated in the the attached proposal, the value of all partially completed work at a fair and equitable price, and the amount of all Extra work performed at the prices agreed upon, or provided for by the terms of this contract, and a reasonable sun to cover the cost of any provisions made by the con- tractor to carry the whole work to completion, and which cannot be utilized. The Owner's Representative shall then make a final statement of the balance due the Contractor by deducting from the above estimate all previous payments by the Owner and all other sums that may be retained by the Owner under the terms of this Agreement, and shalt certify same to the Owner who shalt pay to the Contractor on or before thirty (30) days after the date of the notification by the Contractor the balance shown by said finat statement as due the Contractor, under the terms of this Agreement. 51. BONDS The successful bidder shall be required to furnish a performance bond and payment bond in accordance with Article 5160, Vernon's Annotated Civil Statutes in the amount of 100% of the total contract price, in the event said contract price exceeds $25,000.00.

INDEPENDENT CONTRACTOR Contractor is, and shall remain, an independent contractor with full, complete and exclusive power and au- thority to direct, supervise, and control his own employees and to determine the method of the performance of the work covered hereby. The fact that the owner or Owner's Representative shall have the right to ob- serve Contractor's work during his performance and to carry out the other prerogatives which are expressly reserved to and vested in the Owner or Owner's Representative hereunder, is not intended to and shall not at any time change or effect the status of the Contractor as an independent contractor with respect to either the Owner or Owner's Representative or to the Contractor's own employees or to any other person, firm, or corporation. 55.

Subgrades for concrete structures and trench bottoms shall be firm, dense, and thoroughly compacted and consolidated; shall be free from mud and muck; and shall be sufficiently stable to remain firm and intact under the feet of the workmen. . Subgrades for concrete structures or trench bottoms which are otherwise solid, but which become mucky on top due to construction operations, shall be reinforced with crushed rock or gravel. The stabilizing mate- rial shall be spread and compacted to a depth of not more than 4 inches; if the required depth exceeds 4 inches, the material shall be furnished and installed as specified for granular fills. The finished elevation of stabilized subgrades shall not be above subgrade elevations indicated on the drawings. 10. EMBANKMENT CONSTRUCTION. Embankments shall be constructed to lines and grades indicated on the drawings. 10.01. Compacted Embankment Materials. Generally, native site soils shall be used for construction of reservoir embankments. To the maximum extent available, excess suitable material obtained from excavation shall be used for the construction of embankments. Additional material shall be provided as required at no additional cost to the contract. All material placed in embankments shall be free from rocks or stones larger than 6 inches in their greatest dimension, brush, stumps, logs, roots, debris, and organic or other deleterious materials. No rocks or stones shall be placed in the upper 18 inches of any fill or embankment. Rocks or stones within the allowable size limit may be incorporated in the remainder of fills and embankments, provided they are distributed so that they do not interfere with proper compaction. 10.02. Surface Preparation. Stripped foundation areas of the embankment shall be adequately drained to prevent ponding of water or the formation of swampy areas. The stripped surfaces beneath the embankment construc- tion shall be scarified to a depth of 8 inches, wetted as necessary, and P Y compacted to an average of 95 percent of maximum dry density at minus one to plus three percent as determined by the Standard Proctor compaction € test ASTM D698, to provide good bond between the fill and embankment foundation soils. 10.03. Additional Embankment Subgrade Excavation. Areas where very loose cover sands (N-values of 5 or less as defined in Appendix B of the geotechnical report) are anticipated to be beneath the embankment near borings B-1 and B-2 and shall be undercut to firm subgrade material. The limits and adequacy of the undercutting operation and suitability of the subgrade material shall be subject to agreement by the Engineer. The undercut area shall be wetted and compacted as specified herein, to provide a good bond between the fill and embankment foundation soils. Measurement and payment for excavation and replacement of the material shall be as specified in the measurement and payment section. The (LUBBOCK, TEXAS ? (TERMINAL STORAGE RESERVOIR) (CONTRACT 1 ) 02220 (15388 ) -3- removed material may be used in embankment construction provided it is mixed with other suitable site materials prior to installation in the ? embankment between the fill and embankment foundation soils. 10.04. Embankment Keyway. The embankment keyway shall be installed in existing undisturbed soil and shall be constructed with the dimensions { indicated on the drawings. Soils for the embankment keyway shall meet the requirements for compacted embankment soil as specified herein. If animal burrow holes or tension cracks are observed in the key trench, the key trench shall be deepened below the level of tension cracks or animal burrows. 10.05. Embankment Placement. Following preparation of the embankment foundation, embankment soils shall be placed in loose lifts not to exceed 8 inches and comacted to an average of 95 percent of maximum dry density at minus one to plus three of optimum moisture content as determined by the Standard Proctor compaction test ASTM D698. Embankment soils shall be well processed with a disc, then wetted, and compacted. The soils shall be placed in horizontal lifts and the preceeding lifts, if smooth, shall be roughened to promote bonding between lifts. If necessary, the previous lift shall be scarified lightly and sprinkled to achieve bonding. Succeeding lifts of soil shall be placed as rapidly as possible to prevent drying and cracking of the embankment. Until installation of the soil cement surfacing, the Contractor shall wet the embankment surface as often as necessary to prevent the soils from drying and cracking. Wherever a trench is to pass through a fill or embankment, the fill or embankment material shall be placed and compacted to an elevation not less than 12 inches above the top of pipe elevation before the trench is excavated. 11. GRANULAR FILLS. Granular fills shall be provided where indicated on the drawings. Granular fills shall be placed on suitably prepared subgrades and compacted by vibration. Granular fill material shall be crushed rock or gravel, shall be free from dust, clay, or trash, and shall be graded 1-1/2 inch to No. 4 as defined in ASTM C33. Granular fills shall be compacted to not less than 70 percent relative density as determined by ASTM D4253 and D4254. Where granular fills are to be covered with concrete, the top surface shall be graded to the required subgrade and covered with polyethylene film. 12. OUTSLOPE TOPSOIL. The outslope topsoil shall be a natural friable, fertile, fine sandy loam, easily cultivated and shall have a relatively high erosion resistance. Topsoil shall be readily able to support grass growth and shall be free from subsoil, noxious weeds, stones larger than (LUBBOCK, TEXAS ) (TERHINAL STORAGE RESERVOIR) (CONTRACT 1 ) 02220 g. (15388 ) -4- one inch in diameter, lime, cement, ashes, slag, dispersive clays or other deleterious matter. To the maximum extent practical, suitable top- soil from on -site may be used as outsl.ope topsoil material provided it meets the requirement specified herein. 13. ROAD CONSTRUCTION. 13.01. General Requirements. Materials, procedures, and construction methods shall conform to the following general requirements. Except as otherwise specified herein, all materials and methods shall be as specified in the latest edition of "Standard Specifications for con- struction of Highways, Streets, and Bridges" by the Texas Department of Highways and Public Transportation. 13.02. Flexible Aaareuate Base. The flexible aggregate base shall con- sist of a six inch minimum layer, measured after compaction, of SDHPT 249 Type F, grade 2 material. The base materials shall be compacted by the Density Control method to at least 95 percent of maximum density at optimum moisture content as determined by ASTM D698. 14. TRENCH EXCAVATION. Trenches shall be excavated so that pipes can be laid straight at uniform grade, without dips or humps, between the terminal elevations indicated on the drawings. 14.01. Minimum Cover. Where pipe grades or elevations are not defi- nitely fixed by the contract drawings, trenches shall be excavated to a depth sufficient to provide a minimum depth of backfill cover over the top of the pipe of 36 inches for all piping. 14.02. Limitinz Trench Widths. Trenches shall be excavated to a width which will provide adequate working space and sidewall clearances for proper pipe installation, jointing, and embedment. Minimum trench widths shall be as follows: Nominal Pipe Size Minimum Trench Widths (inches) (inches) Less than 27 Pipe OD plus 24 27 through 60 Pipe OD plus nominal pipe size Cutting trench banks on slopes to reduce earth load to prevent sliding and caving shall be done only in areas where the increased trench width will not interfere with surface features or encroach on right-of-way limits. 14.03. Excavation Below Pipe Subgrade. Except where otherwise required, pipe trenches shall he excavated below the underside of the pipe, as indicated on the drawings to provide for the installation of granular embedment. (LUBBOCK, TEXAS ) (TERMINAL STORAGE RESERVOIR) (CONTRACT 1 ) 02220 (15388 ) -5- 17 14.04. Bell Hoses. Bell holes shall provide adequate clearance for tools and methods used in installing pipe.

Class B bedding shall be used for all PVC pipelines and all other pipelines, not otherwise specified. C. Class C Bedding. Class C bedding shall be used for all pre- stressed concrete and cast iron pipelines. 15.02. Placement and Compaction. Granular embedment material shall be spread and the surface graded to provide a uniform and continuous support beneath the pipe at all points between bell holes or pipe joints. It will be permissible to slightly disturb the finished subgrade surface by withdrawal of pipe slings or other lifting tackle. After each pipe has been graded, aligned, and placed in final position on the bedding material (trench bottom for 6 inch or smaller pipe), and shoved home, sufficient pipe embedment material shall be deposited and compacted under and around each side of the pipe and back of the bell or end thereof to hold the pipe in proper position and alignment during subsequent pipe jointing and embedment operations. Embedment material shall be deposited and compacted uniformly and simul- taneously on each side of the pipe to prevent lateral displacement. Class C embedment shall be compacted to the top of the pipe in all areas where compacted backfill is specified. Whenever crushed rock is used as embedment for 36 inch and larger pipe, the portion above the bottom of the pipe shall be vibrated with a mechan- ical probe type vibrator during placement to ensure that all spaces beneath the pipe are filled. 15.03. Water Barrier. Continuity of embedment material shall be inter- rupted by low permeability water barriers to impede passage of water (LUBBOCK, TEXAS ) (TERMINAL STORAGE RESERVOIR) (CONTRACT 1 ) 02220 (15388 ) -6- through the embedment. Barrier material shall meet soil classification GC, SC, CL, or ML-CL, and shall be compacted to 95 percent of maximum density (see end of section for soil classifications). Material may be finely divided suitable job excavated material., free from stones, organic matter, and debris. Barriers for all pipelines within the limits of the perimeter of the reservoir shall be compacted soil the full depth of granular material, the full trench width, approximately 4 feet long, and spaced not more than 500 feet apart. 16. TRENCH BACKFILL. All trench backfill above pipe embedment shall conform to the following requirements. A layer of backfill material not more than 8 inches deep may be placed over concrete arch encasement or concrete reaction blocking after the concrete has reached its initial set, to aid curing. No additional backfill shall be placed over arch encasement or blocking until the concrete has been in place for at least 3 days. 16.01. Compacted Backfill. Compacted backfill will be required for the full depth of the trench above the embedment where beneath fills or (? embankments. Where the trench for one pipe passes beneath the trench for another pipe, backfill for the lower trench shall be compacted to the level of the bottom of the upper trench. Materials for compacted backfill shall conform to the requirements for materials used for earth fills and embankments. Masses of moist, stiff clay shall not be used. Backfill materials shall be placed in uniform layers not exceeding 8 inches in uncompacted thickness.

(All text figures are in Appendix A.) 1.1 Project Description The terminal storage reservoir will be constructed with earthen berm dikes with overall dike centerline plan dimensions of approximately 1,400 by 2,100 feet. The existing ground surface at the site slopes downward from the northwest corner near El 3189 to the southeast corner near E1 3173. The bottom of the reservoir will be located near E1 3174 and the top of the berm will be established near El 3209. At the northwest corner, this will require a cut of approximately 15 feet to reach the bottom of the reservoir and a berm fill of approximately iOUTHWESTERN LABORATORIES : SOUTHWESTERN LABORATORIES 20 feet. At the southeast corner, little cutting will be required and the berm €ill will extend to a height of approximately 36 feet. Intermediate combinations of cuts and fills will be required at other points along the berm. It is planned to use excavated on -site soils to construct the berms. For preliminary design, interior berm slopes of 3 horizontal to 1 vertical (3H:1V) and .i exterior slopes of 4H:1V have been proposed. i The terminal reservoir will serve to temporarily store secondary treated municipal wastewater during peak flows. It is anticipated that the reservoir will be full for periods of 2 to 3 months and will be at least partially filled most of the time. An overflow spillway will be located in one side of the reservoir. Depending on the permeability of the exposed natural materials, the need for lining the reservoir is anticipated to minimize exfiltration. The need for slope protection is anticipated for exposed berm surfaces.__ At the time of this writing, a liner consisting of a# one -foot thick, compacted, soil-bentonite liner covered by an additional one -foot thick compacted soil protective layer is being considered for the bottom of the :i SOUTHWESTERN LABORATORIES SOUTHWESTERN LABORATORIES reservoir. A soil -cement slope protection cover will be placed over the inside berm slopes. This layer will be placed in horizontal lifts to provide a thickness of at least two feet measured normal to the slope. The one -foot thick soil-bentonite layer will be extended up the slopes, beneath the soil -cement cover, to the normal reservoir elevation. Other alternates for slope protection and lining may be considered further. It is SwL's understanding that the reservoir will be :.operated such that there typically will always be at ...least one foot of water at the bottom to prevent drying of the bottom liner. It is also our understanding that the rate of lowering of the reservoir will typically not exceed about 0.5 feet per day, a rate that likely will not result in a sudden drawdown condition for the inside slopes. An effluent pump station will be located inside of the reservoir in the vicinity of the southwest corner. Based on available information, this reinforced concrete structure will house pumps with a lowest elevation estimated to be near E1 3168. An overall height of up to 35 feet is estimated for this structure. A transfer pump LABORATORIES SOUTHWESTERN LA80RATORIES station to pump from large to small cells and an irrigation pump station are also anticipated. Miscellaneous piping will be included within and around the reservoir area. The piping is anticipated to be installed at depths of 4 to 8 feet below grade. 1.2 Purpose of Study The purposes of this study were to; 1) perform exploration of the subsurface conditions within the project limits, 2) evaluate the pertinent engineering properties of these materials, and 3) provide geotechnical recommendations and consultation for project design. LABORATORIES SOUTHWESTERN LABORATORIES dissolution of Permian salt beds has resulted in regional subsidence with formation of surface collapse depressions, sinkholes, fractures, faults and similar features. Most of these features have been w reportede 11 north of the project site (Refs. 4, 5, 6). Observations .n by SwL's field geologist during the field drilling program did not indicate the presence of collapse types of features in the vicinity of the site. The Ogallala Formation is a regional aquifer which L.: extends to the north across several states. Water table conditions prevail throughout the aquifer and the water table elevation approximately parallels the ground surface (gradient from northwest to southeast). The elevation of the Ogallala water table in the vicinity of the project site is estimated to be near El 3080 (winter, 1978) or approximately 100 feet below the ground surface (Ref. 7). The aquifer is believed to be recharged by direct precipitation, riverbeds, playa lakes, or a 5 combination of these. Most of the groundwater flow ' undoubtedly occurs through the deeper sands and gravels near the bottom of the formation. Hydraulic conductivity values on the order of 10-2 centimeters per second have been estimated for the aquifer in the vicinity of the site with a typical groundwater flow velocity on the order of 18 centimeters per day. SOUTHWESTERN LABORATORIES :SOUTHWESTERN LABORATORIES I A total dissolved solids content on the order of 800 to 1000 milligrams per liter is estimated for Ogallala ^' groundwater in the Lubbock area. 2.2 Soil Conditions' The subsurface conditions at the project site were investigated by drilling 16 soil test borings and excavating 4 test pits at locations shown in Figure 3. 4 €� Field drilling and sampling procedures are described in Appendix B along with boring and test pit logs. Representative soil samples from the test borings were selected for laboratory testing to evaluate their engineering properties. Test procedures and results of g g these tests are included in Appendix C. A The surf icial soils found in all of the test borings and test pits to depths of 1.5 to 5 feet typically consisted- of brown to reddish brown fine clayey sand in a very E loose to medium dense condition. This soil was classified as SC according to the Unified Soil Classification System (USCS) based on laboratory test results and visual observation of the soil samples. At some locations, the surficial soils contained higher silt, a� or clay contents and classified as SC-SM or CL. These soils were identified as eolian cover sands. SOUTHWESTERN LABORATORIES 9 SOUTHWESTERN LABORATORIES 1 In several of the borings, Borings B-5, B-6, B-7, B-8, B-9, and B-10, the surficial sands were underlain by a brown to tan and brown mottled sandy clay, classified as CL, to depths of 9 to 20 feet. This clay was typically stiff to hard in consistency with unconfined compressive strengths of almost 1,200 to over 5,000 pounds per square foot and plasticity indexes of 7 to 23. Results of swell and consolidation tests indicate that these clays are not expansive. Various percentages of calcareous materials were observed in these clays which thus exhibited caiiche-like characteristics at some locations. At greater depths in these borings and beneath the cover sands at shallower depths in the remaining borings, reddish brown to tan to pink sandy clays to clayey sands (CL to SC) were encountered, typically to the bottom of each boring at depths of 25. to 35.5 feet. This stratum was identified as caiiche on the basis of its color, the presence of abundant visible calcite cementing, and the generally medium dense to dense condition indicated by Standard Penetration Resistance (N-values) of 15 to over 30 blows per foot. At several locations, the shallower caliche materials were found to be in a loose condition with occasional N-values of 7 to 9 blows per foot. Occasional layers of dense reddish brown fine clayey sand L a 9 3 SOUTHWESTERN LABORATORIES SOUTHWESTERN LASORATORIES (SC) or reddish brown sandy clay (CL) were found below or within the caliche stratum. The soils at greater depths in many of the borings were indicated to be in a denser or more cemented condition with several N-values exceeding 50 blows per foot. These soils are believed to represent the upper portion of the Ogallala Formation. Additional details regarding the strata encountered or engineering properties of these materials are included on the boring logs in Appendix B and on the test results sheets in Appendix C. Typical subsurface conditions are also depicted in the generalized stratigraphy profiles around the perimeter, shown in Figures 4 and 5. 2.3 Groundwater Conditions No groundwater was observed in any of the test borings during or at completion of .drilling. Temporary slotted PVC observation wells were installed in four of the test borings (Borings B-1, B-4, B-13 and B-16 at the corners of the reservoir) to permit groundwater observations to be made during the course -of the field operations. These wells were observed to be dry 48 hours after drilling was completed. �s f SOUTHWESTERN LABORATOMES t i { SOUTHWESTERN LABORATORIES 3.0 ANALYSES AND RECOMMENDATIONS The above information regarding the project and the subsurface conditions encountered were evaluated to develop the design and construction recommendations presented in this report section. 3.1 Preliminary Recommendations, Pump Station = structures 3 The location and plan geometry of the effluent pump station have not been determined at the time of this dwriting. However, it is understood that this structure will be located inside the reservoir in the vicinity of the southwest corner. Based on the soil conditions disclosed in Borings B-11 through B-14, the most suitable bearing material for a shallow spread footing or mat -type foundation would consist of the medium dense to dense sandy clay to clayey sand caliche, below any looser materials, found below depths/elevations summarized in Table 1. B ° Table 1: Recommended Bearing Depth/Elevation, Effluent Pump Station Boring No. Recommended Bearing Depth/Elevation. feet B-11 9/3171.5 B-12 3/3178.5 B-13 4/3172.5 B-14 7/3170.5 i a SOUTHWESTERN LABORATORIES =50UT„WESTERN LABORATORIES d The anticipated bearing elevation for the effluent pump> station, E1 3168, is below the above highest bearing levels and is well into the recommended bearing stratum. An allowable soil bearing pressure of up to 5,000 pounds per square foot is recommended for the design of mat -type or spread footings bearing in firm undisturbed natural caliche materials at or below the depths and elevations 'r in Table 1. All foundation elements should be situated at least 2 feet below final exterior grade at the structure locations. In addition, spread footings, if used, should have a minimum plan dimension of 3 feet. The above recommended allowable soil bearing pressure includes a bearing capacity safety factor of 3 or higher. Foundation settlements will depend on the T average foundation contact pressure, the plan geometry of . e the foundation, and the actual location of the structure. In general, it is anticipated that foundations designed using the above recommended allowable bearing pressures and depths will experience only limited settlements, on the order of one inch or€ less. The locations of the irrigation and transfer pump stations are not known at the time of this writing. In U, SOUTHWESTERN LABORATORIES a SOUTHWESTERN LABORATORFES 5 general, the above recommendations for the effluent pump station can serve as guidelines for foundation slabs bearing in natural caliche materials. For foundations bearing in the stiff to hard clays beneath the cover sand (found in Borings B-5 through B-10) or in well -compacted (controlled) engineered fill composed of on -site soils, -` allowable bearing pressures of up to 2,500 pounds per ^' square foot can be considered for preliminary design purposes. After the structure locations, bearing depths and related information are established for each of the pump station structures, it is recommended that the bearing pressures and settlement estimates be reviewed by this office. v, It is SwL's understanding that vertical walls for pump station structures may extend below final grades for a distance of approximately 5 to 10 feet at some . locations. If backfill for these walls will support a i+ liner or if the backfill is located within compacted fill areas for the berms, then it is assumed that the backfill itself will need to be compacted to reduce surface .' settlements. Lateral earth pressures exerted by the backfill on below -grade walls will depend on the backfill M t .,. SOUTHWESTERN LABORATORIES: g'} SOUTHWESTERN LASORATOAIES type, assumed groundwater levels, weight of compaction equipment, and other factors. Recommended equivalent fluid pressures for use in design for two compacted backfill types, compacted with light equipment, are summarized in Table 2.

The piping should be designed to accommodate the anticipated earth loads consistent with the bedding and trench conditions. All trench backfill should be mechanically compacted to the recommended minimum dry densities as discussed in Section 3.5. In areas where the piping passes beneath the berms or other critical elements, care should be exercised to minimize the SOUTAVVESTERN LABOAMORIES potential for unwanted seepage through the piping backf ill. This may require the use of seepage collars, clay plugs, or other means at critical locations. 3.3 Embankments and Slopes Analyses and recommendations for the proposed cut slopes and berm embankments required for the reservoir are included in the following paragraphs. 3.3.1 Material Types and Zoning A review of the generalized subsurface profiles, Figures 4 and 5, indicates that three general soil types will be removed from the reservoir excavation and available for berm construction. These include brown fine clayey sand (cover sand, classified as SC and SC--SM), reddish -brown, tan, pink sandy clay to fine clayey sand (caliche, CL, SC), and brown and tan sandy clay (CL). The laboratory permeability tests and classifications for the exposed and recompacted caliche materials indicate the need for a reservoir liner. The cover sand appears to be the most suited on -site soil for -use in a soil -cement mixture, since the carbonate content of this soil appears to be less than for the other soils among other factors. (Liner considerations will be discussed further in Section 3.4.) �§ I SOUTHWESTERNUl80RATORIES _ SOUTHWESTERN LABORATORIES iE Because of the general similarity of the remaining two soil types and because of the varying berm heights in .' combination with soils exposed in cut slopes, there appears to be little advantage in attempting to sort materials for placement in a zoned embankment section. 6` In general, it is recommended that the more clayey soils (tan and brown sandy clays) be placed close to the inside slope surfaces in an attempt to utilize the low -permeability soils (by classification) immediately - beneath the liner and thereby tend to reduce the overall exfiltration from the reservoir. However, over - �x excavation of caliche materials on the inside cut slopes or reservoir bottom to provide for a continuous "plating" of the soils as a sub -liner layer does not appear to be practically warranted. In these areas, it appears more ' feasible to provide a relatively impervious liner for exfiltration control. Therefore, for purposes of 1 analysis and design, it has been assumed that the embankments will be constructed as a homogeneous cross --section. 3.3.2 Slope Stability Two representative berm cross -sections were selected for slope -stability analyses. Section A is located near the northwest corner (Figure 3) which includes a combination 89 B - SOUTHWESTERN LABORATORIES 2 i< t .� SOUTHWESTERN LABORATORIES 2.0 GENERAL SUBSURFACE CONDITIONS The subsurface conditions at the proposed site were investigated by site reconnaissance observations, reviewing available published geological information, by drilling soil test borings, and by excavating test pits with related laboratory tests performed on selected samples obtained from these borings and pits. 2.1 Regional and Site Geology The City of Lubbock and the proposed reservoir site are located within the Southern High Plains physiographic province which is a well-defined, topographically isolated plateau that slopes downward to the southeast. Soils developed in this area typically consist of fine sandy loans. Numerous depressions or playa basins are located in many areas of .the plains region and these basins form ephemeral lakes. The basins are thought to be a result of eolian deflation. In the semi -arid to subhumid climate, large areas have poorly developed drainage systems with intermittent streams or streams with small perennial flow. Numerous playa lakes and basins are present in the vicinity of the reservoir site (Ref. 1). The primary regional drainage feature is the Yellow House Canyon cut by the Double Mountain Fork of LABORATORIES SOUTHWESTERN LABORATORIES i r the Brazos River flowing to the southeast, located approximately one mile southwest of the site. The surface soils consist of Quaternary -Age windblown cover sand. This typically consists of a fine -to I medium -grained, calcareous, silty sand with caliche nodules with a typical thickness of up to 25 feet with locally thinner areas (Ref. 2). The cover sands overlie the Tertiary -Age Ogallala Formation which contains both coarse fluvial conglomerate and sandstone along with fine-grained eolian sand, silt and clay. A resistant caliche layer is typically found near the top of the Ogallala Formation. The caliche r develops as an authigenic accumulation of calcium carbonate resulting from soil -forming processes, precipitation from groundwater, or a combination of these. The caliche forms in layers or zones, locally y cemented, at varying depths. The combined thickness of the Ogallala and Quaternary deposits at the site is estimated to be on the order of 100 feet or so (Ref. 3). A regional geologic cross section near the project site is shown in Figure 2. The Ogallala overlies southeast dipping Cretaceous strata I and deeper Triassic and Permian strata.

A truck -mounted, rotary drilling rig was used to advance the borings and to obtain samples for laboratory evaluation. A tractor -mounted backhoe was used to excavate the test pits. The drilling sampling operations were performed under the supervision of a SwL engineering geologist. Final boring locations and ground surface elevations were furnished by B&V personnel. Standard Penetration Tests (SPT) were conducted at intermittent depths in each boring. This test consists of determining the number of blows required for a 140-pound hammer dropped 30 inches to drive a standard, 2-inch split barrel sampler is inches. The number of blows are recorded for 6-inch increments and the total for the last 12 inches is reported on the logs. LABORATORIES SOUTHWESTERN LABORATORIES Also at intermittent intervals, "undisturbed" specimens a� of cohesive soils were obtained with 3-inch diameter thin -walled, seamless, Shelby tube samplers. These soil specimens were extruded in the field and wrapped to protect them from disturbance and to maintain their in -situ moisture content. Bulk samples of representative soils were obtained from three of the four test pits as indicated on the test pit logs. All samples were removed from the sampling devices in the field (except as otherwise noted above), logged, and classified in the field by SwL's engineering geologist. The standard penetration test and tube samples were wrapped in aluminum foil, sealed in plastic and stored a temporarily in core boxes at the site. The bulk samples -' were sealed in large plastic bags. All samples were transported to SwLTs Dallas office Laboratory at the completion of the field work.3 Small (2-inch) diameter PVC temporary observation wells were installed in each of the four corner borings, s' Borings B-1, B-4, B-13, and B-16. Groundwater observations were made at these locations during the field program.

Re: Supplemental Report Geotechnical Investigation Terminal Storage Reservoir Lubbock, Texas (B&V Project 15388.201; SwL Report No. 89-308-1) Gentlemen: Submitted herewith are the results of SwL's additional tests on the on -site cover sands for the referenced project. This report is a supplement to our recently submitted geotechnical investigation report (SwL Report No. 89-308, Draft dated July 25, 1989). This series of tests was performed on a composite sample of the cover sands, which included standard penetration test samples at depths of 0 to 1.5 feet from Borings 1 through 12 and Boring 15. The percentage of fines for this sample was similar to that obtained for the previously tested samples of this stratum from Test Pits TP-3 and TP-4 (39.5 percent passing the No. 200 sieve). However, the fines in this sample were found to be slightly more plastic than for the previous samples (Plasticity Index of 7 vs. 5 previously). A coefficient of permeability of 2.8 x 10-8 centimeters per second (cm/sec) was obtained from the "raw" composite sample (without bentonite or cement) compacted to a nominal dry density of 95 percent of the Standard Compaction maximum dry density (ASTM D698). For, a similarly compacted sample with 6 percent dry bentonit� added, a coefficient of permeability of 1.2 x 10 cm/sec was obtained.
