Irrigated Lands Regulatory Program
California agriculture is extremely diverse and spans a wide array of growing conditions from northern to southern California. California's agriculture includes more than 400 commodities. The state produces nearly half of US-grown fruits, nuts and vegetables. Across the nation, US consumers regularly purchase crops produced in California. Many of the products are exported to markets worldwide.
Water discharges from agricultural operations in California include irrigation runoff, flows from tile drains, and storm water runoff. These discharges can affect water quality by transporting pollutants, including pesticides, sediment, nutrients, salts (including selenium and boron), pathogens, and heavy metals, from cultivated fields into surface waters. Many surface water bodies are impaired because of pollutants from agricultural sources. Groundwater bodies have suffered pesticide, nitrate, and salt contamination.
To prevent agricultural discharges from impairing the waters that receive these discharges, the Irrigated Lands Regulatory Program (ILRP) regulates discharges from irrigated agricultural lands. This is done by issuing waste discharge requirements (WDRs) or conditional waivers of WDRs (Orders) to growers. These Orders contain conditions requiring water quality monitoring of receiving waters and corrective actions when impairments are found. The number of acres of agricultural land enrolled in the ILRP is about six million acres. The number of growers enrolled is approximately 40,000.

About the Program
- About the Irrigated Lands Regulatory Program (Ag Waivers)
- Irrigated Lands Regulatory Program (ILRP) Monthly Report
The State Water Board is pleased to provide a link to the public to review monthly status reports on the ILRP. The monthly reports will provide updated ILRP information. The first monthly report will be on the Central Valley Water Boards program. Alternate monthly reports will be on the other Regional Board ILRPs.
- Fertilizer Research and Education Program (FREP)
FREP was established in 1990 through a legislative action to provide funding for research and education regarding the use and handling of fertilizing material, including, but not limited to, any environmental effects. The program is part of the California Department of Food and Agriculture (CDFA), Division of Inspection Services, within the Feed, Fertilizer, and Livestock Drugs Regulatory Services branch.
- Impaired Water Bodies
Listing a water body as impaired in California is governed by the Water Quality Control Policy for developing California’s Clean Water Act Section 303(d) Listing Policy. The State and Regional Water Boards assess water quality data for California’s waters every two years to determine if they contain pollutants at levels that exceed protective water quality criteria and standards. This biennial assessment is required under Section 303(d) of the Federal Clean Water Act. See a map of water bodies (click on the Map tab) that have been identified as impaired by agricultural related pollutants such as pesticides or nutrients.
