ADEQ's MSGP 2010 - Posted for Informal Stakeholder Review and Input
The informal draft documents of ADEQ's new industrial stormwater general permit, to be known officially as the AZPDES Multi-Sector General Permit, or MSGP 2010, are posted below.

PowerPoint Presentation Summaries
The AZPDES MSGP 2010 contains eight parts and five appendices. Parts 1 through 7 describe the requirements that all operators must meet when seeking coverage under this permit. Part 8 describes the additional sector-specific requirements for industrial activities, sub-divided into 30 industry sectors. A permittee need only comply with the additional requirements of Part 8 that apply to the sector(s) of industrial activity for that facility. Please be advised, however, that these sector-specific requirements are in addition to the basic requirements of all facilities specified in Part 1 - 7 of this general permit.
All facilities in Arizona subject to ADEQ's MSGP 2010 will be required to apply or reapply when the permit is issued. MSGP 2000 permittees of record will be notified directly by US Mail when the new permit becomes effective. Other interested stakeholders (those who are not current permittees) should bookmark this web page and return to it often.
ADEQ appreciates the opportunity to continue to work with stakeholders in developing this latest of AZPDES General Permits. With the completion of the informal stakeholder process, the next major step will be the formal public participation process, which will include ADEQ's revisions to the MSGP 2010 based on the input from the informal stakeholder process. ADEQ anticipates the draft MSGP 2010 to be public noticed sometime during the summer of 2010. Watch for announcements and updates on this page, or ADEQ's main Web page ("What's New at ADEQ?").

ADEQ's MSGP 2010 in relation to EPA's new MSGP 2008
EPA re-issued a new Multi-Sector General Permit (MSGP 2008) that became effective on Sept. 29, 2008. This permit replaces the MSGP 2000, which expired Oct. 30, 2005. However, EPA's new MSGP only applies to facilities in states and territories that are not authorized to implement the National Pollutant Discharge Elimination System program. ADEQ was delegated to administer this program in December 2002; therefore EPA's MSGP 2008 is only applicable in Arizona to facilities located in Indian Country lands.
Note: Operators with facilities in Arizona will be covered by a separate Arizona-specific MSGP and should disregard the January 05, 2009 filing deadline listed in EPA's MSGP 2008.
Facilities covered under the MSGP 2000
ADEQ assumed the MSGP 2000 as an Arizona permit in December 2002, when the department received NPDES program authorization. Until ADEQ replaces the MSGP 2000, facilities in Arizona that obtained coverage under this permit prior to its expiration on Oct. 30, 2005 still have permit coverage under an administrative continuance. This status will not change until ADEQ issues a new permit. Operators already covered under MSGP 2000 must continue to implement their SWPPP and comply with the requirements in the MSGP 2000.
Do not submit a Notice of Intent (NOI) or a Notice of Termination (NOT) to EPA or ADEQ for the MSGP 2008 (unless your facility is located in Indian Country lands), even if you received a postcard from EPA instructing you to do so.
New and existing facilities without permit coverage
Operators in Arizona that did not obtain coverage under the MSGP 2000 before it expired in October 2005 are not administratively continued and will not be able to obtain coverage under a general permit for stormwater discharges associated with industrial activity until ADEQ issues a replacement permit. In the interim, ADEQ recommends operators review the draft ADEQ MSGP 2010 (the downloadable version provided above). Read Part 2.1 (Control Measures), Part 4 (Inspections) and then prepare a SWPPP in accordance with Part 5. ADEQ suggests using EPA's SWPPP template (link cited above) and modify the facility's SWPPP to Arizona-specific conditions. Preparing a SWPPP demonstrates an operator's intent to comply with the industrial stormwater program, which, in simplest terms means writing and implementing a SWPPP that minimizes pollutants exposed to stormwater. Knowing that new facilities cannot obtain coverage yet, ADEQ will use its enforcement discretion for those without coverage.
