NPDES Stormwater Multi Sector General Permit for Industrial Activities TNR050000
*** Important Update 07/20/2020***
New Tennessee’s general industrial stormwater discharge permit is known as the Tennessee Multi Sector Permit (TMSP) became effective on July 20, 2020, for a period of two years.
Tennessee’s 2015 TMSP reflected the 2015 federal Multi Sector General Permit (MSGP), which expired on June 4, 2020. EPA has proposed a 2020 MSGP that is fundamentally different from the previous permit and from Tennessee’s 2015 TMSP. The comment period for the federal MSGP ended June 1, 2020, and the final permit is not anticipated until November 12, 2020.
Rather than wait for EPA’s final 2020 permit to inform Tennessee’s 2020 TMSP, TDEC decided to reissue the 2015 TMSP, unchanged, for a term of two years. This will provide an opportunity to review the final federal MSGP prior to proposing any changes to the TMSP. Reissuing the 2020 TMSP for a two-year term will avoid impacting new industrial facilities who would be unable to receive permit coverage without an active TMSP in Tennessee.
If you DO NOT have coverage under the previous TMSP:
If you have reviewed the information on this page to confirm that you need coverage, please submit a completed Notice of Intent (NOI) and stormwater pollution prevention plan (SWPPP) to Water.Permits@tn.gov.
If you have coverage under the current TMSP and plan to maintain it in the next permit cycle:
Do not submit a NOI for coverage under the new permit. Facilities covered under the previous permit will receive an updated Notice of Coverage (NOC) for the two-year reissuance period.
If you have coverage under the current TMSP but no longer need it:
Submit the appropriate documentation (No Exposure Certification Form or Notice of Termination) immediately. (see forms below)
This is a general NPDES permit required for facilities that have significant industrial materials exposed to rainfall and resulting stormwater.
