Sand & 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.

The current permit went into effect April 1, 2026, and expires March 31, 2031.

Public involvement in the reissuance

The Sand and Gravel General Permit was reissued April 1, 2026. The previous permit was issued February 17, 2021, effective April 1, 2021, and expired March 31, 2026.

Two online public meetings and hearings were held during the public comment period on the draft permit in August and September 2025. We received written comments from online, mail, and email, and spoken comments were recorded during the hearings. All comments and our responses are compiled in an appendix to the fact sheet. 

You can read more about the permit’s public comment period in our blog on New clean water protections proposed for sand and gravel facilities.

Do I need a permit?

You may need a Sand and Gravel General Permit if your facility:

  • Discharges process water, stormwater, or mine dewatering water into waters of the state.
  • Is associated with sand-and-gravel operations, concrete batch plants, or asphalt batch plants.

You may need a portable operation permit if you move from site to site to:

  • Crush rock
  • Make concrete
  • Make asphalt

Concrete characterization study

Concrete is widely used in construction because it is resilient, affordable, and easily available. At the end of their use, concrete structures and products are demolished into rubble (broken up pieces). This rubble can get stored, recycled and reused as building material. Ecology’s recent literature review of concrete leachate reviewed over 200 articles, reports, and papers published in the U.S. and internationally. This helped Ecology understand the potential pollutants sourced from concrete manufacturing and recycling. Ecology developed a Quality Assurance Project Plan detailing Ecology’s methods and procedures. For more information about this study, see blog post about this project.

Ecology will publish a report detailing the results of our characterization of concrete process water and stormwater study later in 2026.
