On June 19, 2012, the State Water Resources Control Board (State Water Board) adopted the Water Quality Control Policy for Siting, Design, Operation, and Maintenance of Onsite Wastewater Treatment Systems (OWTS Policy). The OWTS Policy provides criteria for siting, design, operation and maintenance of onsite systems and provides a conditional waiver for onsite systems that comply with the policy. Applicable state-wide, the OWTS Policy designates regional boards with principal responsibility for overseeing its implementation and calls for incorporation of the OWTS Policy requirements into regions' basin plans within a year of the policy's effective date.
On May 8, 2014, the Los Angeles Regional Water Quality Control Board (Los Angeles Water Board) adopted Resolution No. R14-007 amending the Water Quality Control Plan for the Los Angeles Region (Basin Plan) to incorporate the OWTS Policy. The State Water Resources Control Board approved the amendment under Resolution No. 2014-0056, on October 7, 2014.
This Basin Plan amendment revises sections of the Basin Plan to delete redundant or conflicting language pertaining to onsite wastewater systems, and incorporates by reference the provisions of the State Water Board's OWTS Policy.
