Delta Submittals & Reviews

The Central Valley Water Board adopted Waste Discharge Requirements General Order (Order) for the San Joaquin County and Delta Water Quality Coalition in March 2014 (Revised April 2015). 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. test

  • Surface Water Sediment Discharge and Erosion Assessment Reports (SDEAR) and Reviews
    The goal of the report is to determine which irrigated agricultural areas are subject to erosion and may discharge sediment that may degrade surface waters. The objective of the report is to determine which Member operations are within such areas, and need to develop a Sediment and Erosion Control Plan.
