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 Irrigated Lands Regulatory Program (ILRP). If you are a Member of the Colusa Glenn Subwatershed Program (CGSP), see below for your new requirements.
Why a new ILRP? 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, CGSP 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 ILRP, 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 ILRP 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 ILRP requirements are below:
- Increased Surface Water Quality and NOW Groundwater Quality Reporting (not the amount of water)
- Mandatory Farm Evaluation Surveys
- Nitrogen Management Plans
- Sediment and Erosion Control Plans
