The Washington State Department of Ecology has reissued the Sand and Gravel National Pollutant Discharge Elimination System (NPDES) and State Waste Discharge General Permit, effective April 1, 2016. The final permit and response to comments, as well as information about upcoming workshops in March and April, can be viewed on the Department website.

According to the Department of Ecology, these “significant changes” between the formal draft and the final Sand and Gravel General Permit were made:

  • Removed General Condition G7. Engineering Plan Review Required from the permit.
  • Revised S8.F.1 so that the BMPs for the placement of concrete recycling stockpiles will only apply to new sites that receive permit coverage for the first time on or after April 1, 2016.
  • Removed Appendix C - Pollution Prevention Schedule for pH.
  • Revised Table 2 to allow process water discharges from NAICS Code 324121 to ground (except for discharges from wet scrubbers).
  • Removed the source control BMP for release agents (S8.E.8 in the formal draft permit).
  • Removed the language which would have prohibited portable facilities from operating at more than one site.
