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.

• DRAFT Permit (Parts 1 - 7) - Revisions based on 09/24/09 meeting
• DRAFT Permit (Part 8)
• DRAFT Appendices
• DRAFT Fact Sheet
• DRAFT Notice of Intent Form
• DRAFT Notice of Termination Form
• DRAFT No Exposure Exclusion Form
• DRAFT Annual Report Form
• DRAFT MSGP Discharge Monitoring Report Form
  
  

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 particpation process, which will include ADEQ's revisions to the MSGP 2010 based on the input from the informal stakeholder process. At this time, ADEQ anticipates the MSGP will be public noticed before Christmas 2009. 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 Jan. 5, 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. Note: 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 prepare a stormwater pollution prevention plan and implement the control measures of EPA's new MSGP 2008. ADEQ plans to use its enforcement discretion for those without coverage.
