Each of the 9 regions
Each of the 9 regions agricultural runoff . The goal of regulations to remedy agricultural runoff is common amongst the regions, although each region contains unique irrigation practices and previous regulatory actionsif any at all. These unique circumstances cause each region to form preferential regulatory approaches and lead to differences amongst the regions.
Revision as of 13:54, 12 April 2012California Water Code requires some combination of Waste Discharge Requirement (WDRs), conditional waivers of WDRs (ag waivers) and/or basin plan prohibitions. WDRs and conditional waivers are adopted as permits and requirements and can include discharge prevention, implementation of management practices, water quality monitoring, remediation and reporting. WDRs implement applicable water quality control plans to protect receiving waters and consider beneficial uses, suitable water quality objectives, nuisance prevention and other waste discharges . Although waivers of WDRs are less intensive, permitting requirements are not simply abandoned; rather permittees must follow a certain set of conditions specified in the conditional waiver that are designed to avoid water quality violations while the waiver can be terminated at any time . The conditional waiver does not hinder the need for other required permits and does not prevent the establishment of additional requirements as authorized by the California Water Code. A prohibitions approach simply restricts certain types of discharges such as municipal, industrial or hazardous wastes while the level of discharge risk to water quality determines the requirements of WDRs and ag waivers . The Porter-Cologne Water Quality Control Act 1969 is the primary law regulating the quality of both surface and ground waters. This Act makes the California State Water Resources Control Board (SWRCB) the agency responsible for water quality planning statewide and grants the Regional Water Quality Control Boards (RWQCBs) authority. The RWQCBs are responsible for the enforcement of WDRs, ag waivers and prohibitions. California contains nine Water Quality Control Regions, each regulated by its own RWQCB. Therefore each region regulates discharge from agricultural irrigation independently with different conditions and variations of the required regulatory approaches as shown in the Central Coast Region Agricultural Waiver.

Each of the 9 regions contain agricultural runoff issues. The goal of setting regulations to remedy agricultural runoff is common amongst the regions, although each region contains unique irrigation practices and previous regulatory actions; if any at all. These unique circumstances cause each region to form preferential regulatory approaches and lead to differences amongst the regions.
Each RWQCB is tailored to a specific region. The regulations that are established are specific to types of irrigated land and environmental concerns within a region. For example, the regulations in San Francisco will be different then the regulations in Los Angeles because the agricultural settings are different (San Francisco is currently developing a conditional waiver program for vineyard facilities). Vineyard facilities are a larger concern for agricultural runoff in San Francisco then in Los Angeles.
The 9 RWQCBs for California are:
Region 1 -- North Coast
Region 2 -- San Francisco
Region 3 -- Central coast
Region 4 -- Los Angeles
Region 5 -- Central Valley
Region 6 -- Lahontan
Region 7 -- Colorado River Region
Region 8 -- Santa Ana
Region 9 -- San Diego
