The Arizona Department of Environmental Quality (ADEQ) has updated the permit for the Multi Sector General Permit (MSGP). The 2019 MSGP replaces the 2010 MSGP and facilities have until February 28, 2020 to obtain the following:

  • No exposure certification
  • No discharge certification
  • Notice of Intent (NOI) under the 2019 MSGP

If a facility is required to submit an NOI, Storm Water Pollution Prevention Plans (SWPPPs) will need to be updated and submitted through the myDEQ website prior to applying for the NOI.

The new 2019 MSGP can be viewed on the ADEQ website. ADEQ also released a fact sheet summarizing the changes to the 2019 MSGP.

Please contact Trinity's Phoenix office at (602) 274-2900 for more information or assistance in obtaining coverage under the 2019 Multi Sector General Permit.
