Sand and Gravel General Permit

The Sand and Gravel General Permit regulates discharges of process water, stormwater, and water from mine dewatering into waters of the state associated with sand and gravel operations, rock quarries, and similar mining operations. The permit also covers concrete batch operations and hot mix asphalt operations. Untreated discharge water from sand and gravel operations may harm fish, aquatic life, and water quality.

Permit Modification Public Comment Period until December 8

Ecology reissued the Sand and Gravel General Permit on February 17, 2016. The reissued permit was appealed by the Washington Aggregate and Concrete Association. A settlement was reached on modified language for the permit in August 2017.

The modified language allows more flexibility for portable operations and new concrete recyclers. The appeal resulted in modifications to:

  • pH monitoring for asphalt batch plants and asphalt recycling (S2, Table 2)
  • concrete recycling best management practices (S8.F)
  • coverage for portable facilities (S12.B) and related coverage forms
Ecology must now go out for public comment before adopting the new modified draft language. The draft of the modified permit, revised forms for portable operations, and fact sheet addendum are available for review and public comment from September 26 through December 8, 2017, at 11:59 p.m. We will accept written and oral comments on the modified draft permit langugae and supporting documents. Ecology prefers comments to be submitted by email to carrie.graul@ecy.wa.gov. You must send email comments by 11:59 p.m., December 8, 2017.

Written comments must be postmarked by December 8, 2017. You may submit them to:

P.O. Box 47696
Olympia, WA 98504-7696
A public hearing and workshop on the permit modification will be held in Lacey. At the workshop we will explain the modified permit and answer questions. A hearing will follow the workshop. The hearing will provide the opportunity for formal oral testimony and comments on the proposed permit modifications.

The workshop and hearing will be held at:
November 30, 2017 – 9 a.m.

The final decision on permit modification will be made after we receive and consider all public comments. We expect to issue the permit in January 2018.
