Why do I need an AZPDES Industrial Stormwater Mining Multi-Sector General Permit (MSGP)?

This permit is for stormwater discharges associated with sites of specific mining industry activity, to waters of the U.S. Permit eligibility is limited to discharges from facilities of industrial activity in Sectors G and J, based on Standard industrial Classification (SIC) codes and Industrial Activity Codes.

The MSGP is valid for five years. An initial fee is due at the time the operator submits the Notice of Intent (NOI) fee to ADEQ, and is based on the amount of acreage at the site. Permittees must also pay an annual registration fee based on the acreage of their facility, and fees continue until the industrial activity ceases or the facility closes, at which time the operator files a Notice of Termination (NOT) to end coverage.
