Document Description
The City of Los Angeles, Lead Agency, has prepared a DEIR for the proposed project. The City's Bureau of Sanitation (BOS) owns and operates the Hyperion Treatment Plant (HTP), which treats wastewater and biosolids at 12000 Vista del mar in Playa del Rey. Digester gas produced at HTP is treated to remove sulfur and moisture and is piped to Scattergood Generating Station (SGS) under an energy exchange agreement. This arrangement will continue through to 2017. Instead of flaring the gas, the BOS proposes to beneficially use the renewable digester gas in a combined cycle cogeneration system, ensuring that the HTP has reliable electricity and steam for plant use. Two transformers, a substation, and related interconnections will also be installed. Copies of the DEIR are available for public review.
