EPA’s 1990 stormwater regulations established NPDES permit requirements for “stormwater discharges associated with industrial activity.” EPA issued the first Multi-Sector General Permit [MSGP] for stormwater discharges associated with industrial activity in 1995, and reissued in 2000, 2008 and most recently on June 4, 2015 [40 CFR 122.26(b)(14)(i)-(ix)].
EPA’s MSGP applies only in areas of the country where EPA remains the NPDES permitting authority and has made the permit available for coverage, and includes the following locations:
- Four states: Idaho, Massachusetts, New Hampshire and New Mexico;
- The District of Columbia;
- All U.S. territories except for the Virgin Islands;
- Federally operated facilities in Colorado, Delaware, Vermont and Washington;
- Most Indian Country lands; and
- Other designated activities in specific states (e.g., oil and gas activities in Texas and Oklahoma).
The 2015 provisions are largely similar to 2008. However, EPA made changes to streamline the permit, enhance environmental protection and improve clarity. The following is a summary of the changes:
Summary of changes include:
- Revised threatened and endangered species eligibility procedures
- Adds several technology based effluent limits
- Streamlined SWPPP documentation
- Electronic submission for NOI, notice of termination, annual reports and monitoring
- Reduced requirements for inspections (no longer have to do separate comprehensive site inspections)
- Deadlines for taking correction actions
All facilities that need coverage must submit a Notice of Intent [NOI] under the 2015 permit. If your operation had coverage under the 2008 MSGP, the NOI submission is due no later than September 2, 2015.
