Since the mid 1990s, municipal stormwater agencies (MS4s) have recognized the need to better utilize existing state and federal pesticide regulatory authority to mitigate and prevent pesticide impacts on urban water bodies, and CASQA has actively supported improvements in this area. In the early 2000s, significant progress has been made in how well the California Department of Pesticide Regulation (DPR), and to a lesser degree, the US EPA Office of Pesticide Programs, responds to pesticide impacts, and regulates pesticides to prevent future impacts.

Building on this progress, in 2014 CASQA requested that the State Board establish a statewide policy that recognizes the key role of pesticide regulatory authority for addressing pesticide impairments associated with urban runoff, and supports an ongoing high level of coordination between the State Board and DPR. The Urban Pesticide Amendments to the statewide water quality control plans, which are proposed by the State Board, are responsive to CASQA’s request. The amendments also support establishment of a statewide monitoring framework to better coordinate and more efficiently utilize state, regional, and local resources and obtain data necessary for effective pesticide regulation. Requirements for local agencies will focus on in-house integrated pest management programs and public outreach efforts, which may utilize existing programs that are already available and implemented widely. Participation in regional and statewide programs is expected to provide a resource efficient mechanism for most MS4s to comply with permit requirements derived from the amendments.
