Region 9 NPDES Permits

You will need Adobe Reader to view some of the files on this page. See EPA's PDF page to learn more about PDF, and for a link to the free Adobe Reader.

This page lists EPA-issued Permits for all areas where EPA Region 9 is the permitting authority.  EPA Region 9 is the permitting authority for Tribal lands in Arizona, California, Nevada, and also all Navajo lands; the Pacific Island territories of Guam, American Samoa, Commonwealth of the Northern Mariana Islands; and any discharges into federal ocean waters beyond state boundaries.

For Draft Permits that have not yet been issued, visit the Draft Permit Public Notices page.

Arizona, California, Hawaii and Nevada issue NPDES permits for discharges on lands (other than Tribal lands) within those states.  State-issued permits and related information are accessible through state program websites.

EPA-Issued Permits

Note: Permits not available online may be obtained by contacting EPA.

Stormwater General Permits

Construction: For the areas where Region 9 is the permitting authority, one general permit, the construction general permit (CGP) has been issued for construction sites disturbing one or more acres (73 Fed. Reg. 40338, July 14, 2008). This permit is a reissuance of the previous permit which was issued on July 1, 2003.

Industrial: For the areas where Region 9 is the permitting authority, a second general permit, the multi-sector general permit (MSGP) (65 Fed. Reg. 64746, October 30, 2000) has been issued for industrial facilities other than construction sites. The MSGP of October 30, 2000 is a reissuance of the original MSGP which was issued on September 29, 1995.  The MSGP expired on October 30, 2005 but has been administratively extended.

Construction and Industrial Permit Application:  under the CGP, a construction notice of intent (NOI) must be submitted to EPA. A similar industrial notice of intent is required for the MSGP. Permit coverage under the construction general permit may be terminated by submitting a construction notice of termination. Permit coverage under the MSGP may be terminated by submitting an industrial notice of termination.  EPA Region 9 is involved with CGP and MSGP permits for the following areas: The Islands of American Samoa and Guam, Johnston Atoll, Midway/Wake Islands and Commonwealth of the Northern Mariana Islands; Indian Country in Arizona (as well as Navajo Reservation lands in New Mexico and Utah), California and Nevada (as well as the Duck Valley Reservation in Idaho, the Fort McDermitt Reservation in Oregon and the Goshute Reservation in Utah).

Vessel General Permits

On December 18, 2008, EPA issued a vessel general permit authorizing 26 discharges incidental to the normal operation of commercial vessels 79 feet or longer, but excluding all commercial fishing vessels unless they discharge ballast water. The permit covers all 50 states, Indian lands within the States, and U.S. territories such as Guam, American Samoa and the Commonwealth of the Northern Mariana Islands in Region 09.
