Overview of the Clearwater Program
Final Executive Summary, Master Facilities Plan & EIR/EIS
The Clearwater Program is a comprehensive planning effort undertaken by the Sanitation Districts of Los Angeles County (Sanitation Districts). Its purpose is to develop a long-range Master Facilities Plan (MFP) for the Joint Outfall System (JOS), a regional wastewater management system servingÂ nearly 5 million people in 73 cities and unincorporated county areas, including portions of the city of Los Angeles.
The Clearwater Program MFP evaluates infrastructure and facilities through the year 2050 and makes recommendations on how to maintain a reliable and cost-effective wastewater management system while increasing the use of a valuable resource, recycled water.
The MFP has identified the need for a new onshore tunnel and, possibly, a new ocean outfall to convey treated wastewater effluent from the Sanitation Districts' Joint Water Pollution Control Plant in Carson to the ocean. A new tunnel/ocean outfall would allow for the inspection and any necessary repairs of two existing effluent tunnels, which flow full every day and have not been inspected in over 50 years.
After evaluating over 50 potential project alignments, four feasible alignments were identified. The Sanitation Districts and the U.S. Army Corps of Engineers (Corps) analyzed the potential impacts of each of the four alternatives in a joint Environmental Impact Report/Environmental Impact Statement (EIR/EIS).Â
The draft EIR/EIS and draft MFP were released for public review in early February 2012.Â Three public hearings were conducted in early March.Â The public review period closed on April 10, 2012.Â Â Â Based on environmental considerations, public feedback, constructability, and cost, one alternativeâ€”consisting of a new 18-foot diameter, 7-mile long onshore tunnel only (no new ocean outfall)â€”isÂ the recommended project.
Availability of Final Documents
TheÂ Clearwater Program Executive Summary, MFP, and EIR/EIS have been finalized (see links below).Â The recommended alternative in theÂ final MFP andÂ final EIR/EIS is the same alternative that was originally recommended in the draft MFP and draft EIR/EIS.
