About the Irrigated Lands Program

What is the Irrigated Lands Program (ILP)? 

The ILP is a mandated program through the Central Valley Regional Water Quality Control Board (Regional Board) for irrigated landowners and operators within the Central Valley who have irrigation and/or stormwater leaving their irrigated agricultural lands or managed wetlands. It monitors water quality to ensure safe drinking waters within the State; surface and groundwater.

As of March 12, 2014, there is a new set of water quality regulations imposed on Sacramento River Watershed irrigated agriculture and managed wetland landowners and operators! This is due to adoption of a waste discharge requirements “General Order” for the ILP. If you are a Member of the Yolo County Farm Bureau Irrigated Lands Program, see below for your requirements.

Why a new ILP? 

In 2003, the Central Valley Regional Water Quality Control Board (Regional Board) began implementing a regulatory program on irrigated agriculture by adoption of a Conditional Waiver of waste discharge requirements for discharges to surface water from irrigated agricultural lands. Irrigated landowners joined together to form coalitions in order to comply with the regulations; therefore, Yolo County Farm Bureau formed as part of the Sacramento Valley Water Quality Coalition (Coalition). The Conditional Waiver was extended in 2006 to continue meeting the water quality regulations.

However due to expiration of the old ILP, a new program to meet water quality regulations, surface water and NOW groundwater quality, had to be developed by the Regional Board. Through a stakeholder driven and public review process the ILP is now a 10-year waste discharge requirements General Order with many new reporting requirements for those needing to meet the water quality regulations. Some of the new ILP requirements are below:

  • Increased Surface Water Quality and NOW Groundwater Quality Reporting (not the amount of water)
  • Farm Evaluation
  • Nitrogen Management Plan
  • Sediment and Erosion Control Plan
