Irrigated Lands Regulatory Program (ILRP)
General | Long-term Program | Forms | Grants | Monitoring and Reporting | Contact ILRP
Program Background and Overview
A range of pollutants can be found in runoff from irrigated lands, such as pesticides, fertilizers, salts, pathogens, and sediment. At high enough concentrations, these pollutants can harm aquatic life or make water unusable for drinking water or agricultural uses. The Irrigated Lands Regulatory Program (ILRP) was initiated in 2003 to prevent agricultural runoff from impairing surface waters. The development of the Long-term Irrigated Lands Regulatory Program (Long-term ILRP Q&A, 60 KB, PDF PDF Info), which will protect both surface water and groundwater, is underway.

Regulatory Coverage for Growers
The Central Valley Regional Water Quality Control Board (Central Valley Water Board) has adopted a Conditional Waiver of Waste Discharge Requirements (Conditional Waiver) that contains conditions requiring water quality monitoring of receiving waters and corrective actions when impairments are found.
Coalition Groups
The Central Valley Water Board has allowed growers to combine resources by forming water quality coalitions. The coalition groups work directly with their member growers to assist in complying with Central Valley Water Board requirements by conducting surface water monitoring and preparing regional plans to address water quality problems. Of the estimated 35,000 growers in the Central Valley, there are about 25,000 landowners/operators who are part of one of eight water quality coalition groups:
- Goose Lake Water Quality Coalition
- Sacramento Valley Water Quality Coalition
- California Rice Commission
- San Joaquin County & Delta Water Quality Coalition
- East San Joaquin Water Quality Coalition
- Westside San Joaquin River Watershed Coalition
- Westlands Water District
- Southern San Joaquin Valley Water Quality Coalition
If growers do not obtain regulatory coverage for their waste discharges as a part of a Coalition Group, they must file a Report of Waste Discharge (also referred to as Waste Discharge Requirements, Form 200) and filing fee with the Central Valley Water Board to obtain a grower-specific permit. For additional information, please contact ILRP, or apply to join a Coalition.
Monitoring and Reporting
The Conditional Waiver requires that Coalition Groups prepare and implement Monitoring and Reporting Program (MRP) plans, submit periodic monitoring reports, and monitoring data. When there have been two or more exceedances of the same pollutant at the same site within a three-year period, Management Plans must be prepared and implemented.
