If a TMDL has been established for the waterbody where your site or facility will discharge, and the TMDL (or the state/territory authority) indicates that it applies to construction, industrial, or stormwater discharges, then you must develop a SWPPP that is consistent with the requirements of that TMDL.
Construction activities must comply with all requirements of the CGP, so please review the complete TMDL provisions of the Construction General Permit (PDF) (59 pp, 1.96MB) . Industrial facilities must comply with all requirements in the MSGP-2000, including the provision that all discharges be consistent with established or EPA-approved TMDLs (see section 1.2.3.8.2 in the MSGP-2000 (PDF) (19 pp, 196K)).
There may be additional TMDL-related requirements for your specific state. Certain policies on TMDLs may change. For the most current information, please check this web site or with the TMDL authority each time you plan a construction project.
