Arizona Mining Permitting Guide
PERMITS, AUTHORIZATIONS OR FILINGS:
National Pollutant Discharge Elimination System (NPDES)
(For Activity on Tribal Lands)
LEGAL AUTHORITY:
Clean Water Act Section 402 (b) and 40 C.F.R. Part 123
CONDITIONS REQUIRING PERMITS, AUTHORIZATIONS OR FILINGS:
The U.S. EPA re-issued a Multi-Sector General Permit (MSGP 2008) that became effective
on September 29, 2008. This permit only applies to facilities in states and territories that are
not authorized to implement the National Pollutant Discharge Elimination System (NPDES)
program. The Arizona Department of environmental Quality was delegated to administer this
program in December 2003; therefore U.S. EPA’s MSGP 2008 is only applicable in Arizona
to facilities located in certain tribal lands.
If mining activity is planned for Tribal Lands a NPDES Permit may be required from the EPA
if the tribe is not administering its own approved NPDES program.
