1. Executive Summary

This Emergency Preparedness Plan (EPP) satisfies requirements of Senate Bill 361 (2009) relating to the requirement that certain water service providers ensure emergency operations during an extended power outage. This EPP and associated actions are to comply with Texas Water Code (TWC) amendments enforced by the Texas Commission on Environmental Quality (TCEQ) [Section 13.1395] and the Public Utility Commission of Texas (PUC) [Section 13.1396].

1.1. Water Provider The Coastal Water Authority (CWA) is a governmental agency and political subdivision of the State of Texas, located within Harris, Chambers, and Liberty Counties. CWA is a conservation and reclamation district created to transport and deliver water, acquire and construct all properties and facilities necessary for such purposes. CWA provides untreated surface water to the cities of Houston, Baytown, and Deer Park for municipal purposes, approximately 100 industries and a few agricultural customers. CWA is the contract operator for Lake Houston Dam and Reservoir, and works in close association with the City's Department of Public Works and Engineering.

Construction 09/30/2011

Emergency Generators Available 05/01/2012

1.7. Estimated Construction Costs Lynchburg Pump Station: Based on the data and information available and adjusting for variable speed pumps at required fractional speeds, one gas turbine powered reciprocating engine generators, each capable of producing a nominal 3,000 kW of power are required to meet the minimum raw water demands identified. To reduce costs natural gas turbine engine were evaluated. Units that produce between 10,500 kW and 12,750 kW would provide sufficient capacity and include a substantial reserve, which could be supplied to industrial users. The cost estimate for a single gas turbine engine generator is approximately $17,740,000.

Trinity River Pump Station

: Based on the data and information available, three reciprocating engine natural gas generators producing a nominal 3,000 kW each are needed to meet the minimum raw water demands identified and a third generator for any industrial raw water needs upstream of the Lynchburg Reservoir. The cost estimate for these three gas reciprocating engine generators is approximately $15,728,000.

4-1


4. Plan Exceptions

CWA’s exceptions to Texas Senate Bill 361 (2009) and amendments to the TWC Sections 13.1395 and 13.1396 enforced by the TCEQ and PUC respectively are described in this section.

4.1. Water Pressure Requirements CWA provides raw water that is processed by others into potable water for residential and commercial consumption. CWA is a raw water transporter not a potable water distributor and does not operate any potable water distribution mains. CWA’s end users, surface water treatment plants and industrial customers, do not require any specific water pressure prior to processing and disinfection to potable water or for industrial uses. Therefore, CWA should be exempt from the 35 psi water pressure requirement that is primarily intended for potable water distribution mains.

4.2. Water Quantity Requirements CWA provides raw water that is processed by others into potable water for residential and commercial consumption. CWA is a raw water transporter not a potable water distributor and does not operate any potable water distribution mains or have any potable water connections. Therefore, CWA should be exempt from the 0.35 gallon per minute per connection water quantity requirement.

4.3. Red Bluff Water Treatment Plant CWA owns and operates a 10 MGD industrial water plant that serves only two customers. It is CWA’s position that SB 361 does not apply to the Red Bluff Water Treatment Plant. In addition, CWA has reached an agreement with one of the customers to provide a generator should it become necessary.

5. Estimated Construction Costs

5.1. Lynchburg Pump Station Based on the data and information available and adjusting for variable speed pumps at required fractional speeds, one gas turbine generators, each capable of producing a nominal 3,000 kW of power are required at Lynchburg Pump Station to meet the minimum raw water demand identified by the City of Houston and Deer Park. In an effort to reduce costs natural gas turbine engine were evaluated. Nominal units based on their standard generator sets were identified, one for 15,000 kW and the other for 12,900 kW. Turbine powered production capabilities vary with inlet air temperature; therefore, units do not produce the nominal power. Assuming an air temperature of 90 °F, these units will produce approximately 12,750 kW and 10,500 kW respectively. Given the estimated peak transient load of 6,500 kW and a constant running load of 4,800 kW, it appears that these generators would provide sufficient capacity and include a substantial reserve, which could be supplied to industrial users . The cost estimate for a single gas turbine engine is approximately $17,740,000 (see the cost estimate back up information in Appendix B).

5.2. Trinity River Pump Station Based on the data and information available, three reciprocating engine natural gas generators producing a nominal 3,000 kW each are needed at Trinity River Pump Station to meet the minimum raw water demand identified by the City of Houston, BAWA, and Deer Park. A third generator would be required if any industrial raw water needs upstream of the Lynchburg Reservoir are to be provided. The cost estimate for these three gas reciprocating engine generators is approximately $15,728,000 (see the cost estimate back up information in Appendix B).
