  • On April 19, 2018, the Regional Water Board renewed the Scott River TMDL Conditional Waiver of Waste Discharge Requirements (Waiver) for 5 additional years to address sediment and temperature impairments in the Scott River watershed and provide support for beneficial uses.  The full text of the adopted waiver can be found at the link below.
  • As with previous waivers, The Regional Water Board conditionally waives the requirements for Dischargers to file a Report of Waste discharge and obtain Waste Discharge Requirements pursuant to Water Code section 13269 for all discharges not already authorized under an existing permit or order if dischargers are in compliance with the conditions of the Waiver.  Key findings from the waiver are listed below, but all dischargers are expected to review and understand the requirements of the Waiver.
    • Dischargers are expected to work cooperatively with the Regional Water Board to assess risks to water quality from their operations.
    • Dischargers are expected to implement the best management practices described in Waiver Finding 5(a-q) as appropriate for their operations or work collaboratively with the Regional Water Board to develop new best management practices that provide equal or better water quality protections.
    • Dischargers may be required to develop and submit Grazing and Riparian Management Plans and/or Erosion Control Plans as required by the Regional Water Board’s Executive Officer.
    • Dischargers may be required to develop and implement site specific monitoring and reporting plans as required by the Regional Water Board’s Executive Officer.
    • This Waiver in no way supersedes or limits the requirements of any enforcement actions that are issued by the State Water Board or Regional Water Board.
