INFORMATION . GOVERNMENT City of Lubbock, Texas Southeast Water Reclamation Plant Influent Lift Station Rehabilitation Mr. Soo Koon Soon, P.E. 1625 131" Street City of Lubbock P.O. Box 2000 Lubbock, TX 79457 Dear Soon: B&V Project 140092 5100 B&V File G-1.0 November 15, 2007 Subject. Field Order No. 1 --ATS —Revised During construction, it was brought to our attention that with the pumping changes being made at the influent lift station, the new submersible pumps would no longer be connected to the emergency standby generator. Since these pumps are the only means of pumping flow into the plant, it is necessary to maintain connection of a portion of the pumping capacity to the generator during an emergency condition. The purpose of this letter is to summarize our recommendation to replace the existing Automatic Transfer Switch (ATS) on the existing 1200 amp line that connects MCC100 loads to the emergency standby generator. if the City agrees with the recommendation, the Contractor should be requested to provide a cost proposal to complete the work. Design History Under the current contract, the existing screw pumps are being replaced with submersible pumps to address ongoing maintenance issues that the plant staff has had with the existing screw pumps Each screw pump will be replaced by two submersible pumps The existing screw pumps were fed out of motor control center MCC100, located in the headworks building. Because of the limited space available in the existing headworks building electrical room, the decision was made to construct a new electrical building adjacent to the influent lift station. This new electrical building would house the electrical equipment associated with the new influent lift pumps and provide space for anticipated future equipment for the influent lift station. In addition, the new electrical building motor control center MCC ILS would also subfeed MCC100 and the equipment associated with the headworks (screens, grit, odor control, etc). The loads associated with MCC ILS (including the potential future loads) dictated an increase in the amperage rating of the feed line from the new load center substations to the MCC to 2000 amps. The feed line from MCC ILS to subfeed MCC100 is rated 800 amps. The loads in MCC100 reflect equipment changes and sizes associated with the work in Contract No. 6. The load lists associated with both of these motor control centers is attached to this letter. Emergency Generator System The generator and the associated transformer and conduits were installed in 1999 by another entity under contract with the City of Lubbock. Since there are not any drawings associated with this work, our understanding of the generator and associated items is the following. The system consists of a 1200 amp ATS, 800 amp transformer 480 volt breaker, 500 kVA transformer, and 600 amp transformer 4160 volt switch. The ATS switches to the emergency generator upon loss of normal power. Emergency load can be fed from the existing 500 kVA transformer. Black & Veatch Corporation 9441 LB3 Freeway, Suite 114 Dallas, TX 75243 USA • Telephone: 214.5707000 City of Lubbock Mr. Soo Koon Soon Page 2 B&V Protect 140092 November 15. 2007 The ATS allows the power feed to the headworks and influent lift pumps to be changed from one source to another. The two sources on the ATS are the main plant feed and the standby generator. Normal operation power source is from the main plant feed. Under normal operation of the existing system, the ATS is in line with the main plant feed from the substation, through MCC100, to the headworks equipment and the influent lift pumps. When the generator is required, the ATS switches to the standby source. Normal operation on the rehabilitated system will have the switch in line with the main plant feed from the substation, through MCC ILS, and to the headworks equipment and the influent lift pumps. Since the ATS will be in line with the normal feed, which is being upgraded to 2000 amps with the equipment changes, it is recommended that the 1200 amp ATS be replaced with a 2000 amp ATS. During an emergency condition, not all of the headworks equipment is in operation. Based on conversations with plant staff, only two of the influent screw pumps run during an emergency event, with a few other equipment loads on the headworks. Based on this information, it was assumed that four submersible pumps would be operated off of the generator during an emergency condition with the revised pump configuration. The assumed load list for the emergency generator is attached to this letter. The loads included in the list will not exceed the capacity of the existing generator system. From conversations with plant staff, the size of the generator is adequate for emergency conditions and all components of the system appear to be in good condition. Because loads to the generator are not increasing, the assumption was made that all other components of the emergency system are adequate and therefore will not be modified. Summary Based on revised conditions due to construction of the Influent Lift Station, it is recommended that the existing 1200 amp ATS be replaced with a 2000 amp ATS. The new ATS will be in line with the new MCC ILS. Provided with this letter is a specification paragraph and one -line diagram (Figure A) indicating the new work to be performed. The new specification paragraph should be added to section 16050 following paragraph 2-24 of the Contract Documents.

Office of Water Utilities DATE January 10, 2008 TO Thomas Adams, Deputy City Manager / Director of Water Utilities Aubrey Spear, P.E., Assistant Director of Water Utilities FROM Soo Koon Soon, P.E., Senior Civil Engineer THROUGH Wood Franklin, P.E., Chief Water Utilities Engineer SUBJECT Consider resolution for Change Order No. 4 - ITB #07-711-BM Influent Lift Station Rehabilitation At Southeast Water Reclamation Plant Subject: Contract Resolution — Water Utilities: Consider a resolution authorizing the Mayor to execute Change Order Number 4 to the construction contract awarded to Brown McKee, Inc. for the construction and installation of Automatic Transfer Switch. Summary: This project involves the construction and installation of Automatic Transfer Switch all the needed appurtenances for the installation of the transfer switch, concrete slab extension, additional duct bank and reconnecting all the electrical wiring of the transfer switch area, for the Southeast Water Reclamation Plant for the sum of $93,094.83. On September 1, 1998, as a result of a power failure incident, two million gallons of raw sewage was released into the North Fork of the Double Mountain Fork of the Brazos River at the Southeast Water Reclamation Plant. That incident resulted in a fish kill, which is a violation of Texas Council of Environmental Quality (TCEQ) rules and regulation. On February 19, 1999, TCEQ issued a Notice of Enforcement Action Order to the City of Lubbock and it lasted until February 19, 2004 which required the City to engage in a solution to prevent any further discharge of raw or inadequately treated sewage into the creek in an event of power failure. The City has the option of providing a reliable alternate source of power using standby generators and or retention of inadequately treated wastewater. The City chose the alternate power source route and implemented the necessary corrective actions. A back-up generator was purchased in 1999 to ensure that the Plant met Y2K needs and also the 1999 Agreed Order from TCEQ. When ever, the primary source of power has a failure event, the back up generator automatically comes on provides the power needs of the Southeast Water Reclamation Plant. This automated action of switching from primary source of power to back up power is by using an Automatic Transfer Switch. The back-up generator is used at least once a year due to power failures. Increases in the influent lift station power loads require a larger automatic transfer switch with an increase in the amperage ratings. Even though, the existing back up generator system connection for the influent pumps was determined to have an amperage rating less than the new motor control center that is currently under construction, after several discussions Black & Veatch and City Of Lubbock staff agreed that the rating of the automatic transfer switch should be increased to match all other equipment in the circuit. An increase in the amperage rating requires a new automatic transfer switch. This Change Order No. 4 totals $93,094.83 resulting in a new contract amount of $2,420,233.64. Fiscal Impact: A total of $3,010,073 was appropriated and $1,924,030 is available in Capital Improvement Project number 90359 (Southeast Water Reclamation Headworks Pump Rehabilitation) for this purpose. Recommendation: Staff recommends the approval of the Resolution to amend the contract with Brown -McKee, Inc to a new contract amount of $2,420,233.64. A 145 days time extension will be necessary for the construction of this water main and the new contract completion date will be July 27, 2008.
