Title

Haynes Generating Station Unit 8 Recycled Water Cooling System Retrofit Project

Description

The Los Angeles Department of Water and Power (LADWP) proposes to implement the proposed project, which would modify the Haynes Generation Unit 8 cooling system by removing the existing ocean-water once-through cooling (OTC) system from service and installing a wet cooling system consisting of a cooling tower. This action is necessary to allow for the continued operation of Unit 8 while complying with mandates related to the statewide Water Quality Control Policy on the Use of Coastal and Estuarine Waters for Power Plant Cooling (OTC Policy), implemented by the California State Water Resources Control Board (SWRCB) to establish standards to comply with federal Clean Water Act Section 316(b) to reduce potential effects on aquatic life associated with the operation of cooling water intake structures. Based on a preliminary schedule, the construction of the proposed project is scheduled to begin in late 2024, and primary facilities construction would be substantially complete by mid-2026. The cooling tower would become operational by mid-2027, after a commissioning phase. By implementing the proposed project, Haynes Unit 8 would comply with the OTC Policy by the December 31, 2029, deadline stipulated in the policy to eliminate OTC at Haynes. Project location is 6801 East 2nd Street, Long Beach, CA 90803
