****Please note:  ***Update***  The Mineral Mining General Permit (MMGP), which expires March 31, 2017, will be administratively continued until a new permit replaces it.  The draft replacement permit will be available for review and comment beginning March 29th.  The public comment period runs through April 28th.  You will find the draft permit in the public notice section of the WDEQ website.  Please contact storm water program staff with any questions.  (3/24/17)

Mineral mining and processing (SIC 14) and associated activities, such as mobile hot plants, concrete batch plants and stockpiles are covered by the mineral mining storm water permit. Non-mineral mining activities and fuels, such as coal, should use the general industrial storm water permit.

Please note that the general mineral mining storm water permit is not available to facilities where storm water runoff has the potential to discharge to class 1 waters. Facilities may apply for coverage under an individual storm water permit.  Contact us.

  • Beginning July 1, 2013 payment of permit fees for individual permits and general permit authorizations are required to be submitted with the permit application or NOI form.  All storm water authorizations have variable fees that must be calculated depending upon the NOI date.  The "Fee Calculator" should be used to determine the proper amount to be submitted with each NOI.  Checks should be made out to the "Dept. of Environmental Quality, Water Quality Division.
