The LCC Permittees began working together to address water quality in late 2008 by forming a Technical Committee in response to a draft of the EPA-established Metals TMDLs for the LCC Watershed. The Group, now known as the Los Cerritos Channel Watershed Group, is comprised of the Cities of Bellflower, Cerritos, Downey, Lakewood, Long Beach, Paramount, and Signal Hill, as well as the Los Angeles County Flood Control District and, informally, the California Department of Transportation (Caltrans).
In December 2013, a Memorandum of Understanding (“MOU”) was made and entered into by and between the GWMA and members of the Los Cerritos Channel Watershed Group which consisted of the Cities of Bellflower, Cerritos, Downey, Lakewood, Long Beach, Paramount, Signal Hill, and the Los Angeles County Flood Control District (“District”) for administration and cost sharing to prepare and implement a Watershed Management Program (“WMP”) and Coordinated Integrated Monitoring Program (“CIMP”) as required by the Regional Water Quality Control Board, Los Angeles Region (“Regional Water Board”), National Pollutant Discharge Elimination System Municipal Separate Storm Sewer System Permit Order No. R4-2012-0175 (“MS4 Permit”).
In June 2015, a First Amendment to the MOU was entered into by and between the GWMA and participants to add implementation of the Plans to the scope and purpose of the MOU and to provide a separate cost-share formula for the implementation of the Plans.
