Irrigated Lands Regulatory Program

The Regional Water Quality Control Boards (Regional Boards) regulate discharges from irrigated agricultural lands to surface water and groundwater through the Irrigated Lands Regulatory Program. Regional Boards issue waste discharge requirements (WDRs) or conditional waivers of WDRs (Orders) to growers. These Orders contain conditions such as requiring water quality monitoring waters, implementation of best management practices, and corrective actions when impairments are found.
