Most states have been authorized to implement the NPDES stormwater program, as described in the table below. The Construction General Permit and Multi-Sector General Permit apply only in areas where EPA is the permitting authority. This information can also be found in Appendix B of the CGP (PDF) (6 pp, 145K) and Part 1 of the MSGP-2000 (PDF) (19 pp, 197K). (Note: EPA Region 4 maintains a separate permit (PDF) (104 pp, 1.3MB) for construction activities on Indian Country in Alabama, Florida, Mississippi, and North Carolina.)
