Effective August 14, 2021, the Texas Commission on Environmental Quality (TCEQ) has issued the new 2021 Multi-Sector General Permit (MSGP) for industrial facilities.

Renewals Due by November 12, 2021
Existing permittees have until November 12, 2021 to renew their existing authorizations by submitting a renewal Notice of Intent (NOI) or No Exposure Certification (NEC), as applicable.  Submissions should be made using TCEQ’s online e-permitting system, SEERS/ePermits.
For facilities that discharge stormwater to a municipal separate storm sewer system (MS4), a copy of the NOI or NEC must be provided to the MS4 operator.

Key Changes from 2016 Version
MSGPs expire every five years.  Key changes from the 2016 version include:

• An updated Stormwater Pollution Prevention Plan (SWPPP) must be developed and implemented before submitting the NOI.
• The Delegation of Signatory Authority must be submitted to TCEQ, electronically, and kept with the SWPPP.
• Some facilities may be able to use a representative weather station instead of an on-site rain gauge to monitor rain events.
• TCEQ added requirements for best management practices for rubber, miscellaneous plastic products, and other miscellaneous manufacturing facilities.
