This page contains documents related to the General Industrial Permit (IGP).
Certain industrial facilities are required to seek coverage under the general industrial storm water permit. Facilities most commonly covered in Wyoming are most mines (mineral mines are covered under the mineral mining permit, see above), facilities that produce cement products, many wood product facilities, airports, junk yards, and scrap recycling facilities. Coverage is based on the facility’s Standard Industrial Classification (SIC) code.
Please note that the general industrial 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.
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.
