Document Description
The City of Los Angeles Department of Water and Power (LADWP) is the Lead Agency and has prepared a Draft Initial Study/Mitigated Negative Declaration (IS/MND) pursuant to the California Environmental Quality Act (CEQA) for the North Hollywood Chlorination Stations and NHOU2IR West Treatment Project. LADWP proposes to expand the treatment capacity of its existing Rinaldi-Toluca (RT) and North Hollywood West (NHW) Chlorination Stations and to replace LADWP’s existing North Hollywood Chlorination Station with the new North Hollywood Central (NHC) Chlorination Station within the same property. LADWP would also assume responsibility for the operation of a groundwater remediation facility related to the North Hollywood Operable Unit (NHOU) Second Interim Remedy (NHOU2IR), which is currently being constructed within the same property as the RT Chlorination Station by Honeywell International Inc. under orders from the U.S. Environmental Protection Agency (EPA) pursuant to its authority under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA). The treated water from the NHOU2IR facility would be directed to the expanded RT Chlorination Station, where it would be disinfected. The proposed project would provide the capability to safely and effectively disinfect water pumped from the RT Well Field, the NHW Well Field, and the western portion of the NHOU, all of which would be operated in a manner consistent with LADWP’s historical use of its well fields to help meet current and projected demand for drinking water in the City of Los Angeles (the City). The Project would not involve any increase in LADWP’s groundwater pumping rights. This disinfection capability would help ensure the reliability and sustainability of the City’s drinking water system by reducing dependence on imported water supplies, consistent with goals established in the 2020 LADWP Urban Water Management Plan.
