The San Joaquin County & Delta Water Quality Coalition was established to help irrigated agriculture meet the requirements of the California Regional Water Quality Control Board's (RWQCB) Irrigated Lands Regulatory Program (ILRP) in San Joaquin County, Calaveras County and Contra Costa County. Under the ILRP that was originally adopted in July of 2003, farmers and ranchers that irrigate their land and have runoff from that irrigation or rainfall must belong to a coalition or apply for an individual discharge permit from the Regional Board directly.
The Coalition is a membership based coalition that implements programs that help farmers and ranchers reduce their impacts to the Waters of the State of California. These programs include best management practices (BMP), workshops, grower meetings, pesticide application information workshops and monitoring of water quality as required by the RWQCB .
It is important for farmers and rancher to understand that this program is required by law and all of those who irrigate their land must comply with the ILRP or face possible regulatory action by the state RWQCB.

The new General Order requires anyone who farms and has the potential to discharge to surface waters or groundwater to either belong to a third party water quality coalition or apply for an individual permit. The San Joaquin County and Delta Water Quality Coalitiion is the third party for San Joaquin County, Calaveras County, the Delta portions of Alameda and Contra Costa Counties, portions of Stanislaus County north of the Stanislaus River, and a small portion of Amador County that drains into the Mokelumne River.
