Sacramento Valley Submittals & Reviews

The Central Valley Water Board adopted the Waste Discharge Requirements General Order (Order) for the Sacramento Valley Water Quality Coalition in March 2014. The concept of higher and lower vulnerability areas was integrated into the Order to allow the board to tailor requirements to applicable waste discharge conditions. To determine what areas are vulnerable to surface water or groundwater impacts due to irrigated agriculture, the third-party representing growers is required to prepare assessment reports.

  • Surface Water Sediment Discharge and Erosion Assessment Reports (SDEAR) and Reviews
