Upcoming Deadline for MSGP Facilities to Report in NetDMR

March 2023 – Multi-Sector General Permit facilities must submit electronic Discharge Monitoring Reports of all required monitoring results by March 31, 2023.

Facilities must submit results through the NetDMR electronic reporting system if they:

  • Must meet federal effluent limits within sectors A, C, D, E, J, O, and S (find a full list of activities required to meet federal effluent limits in Part III.C.2 Table 3 of the MSGP, TXR050000).
  • Must meet numeric effluent limits for hazardous metals and must report exceeding a limit.
  • Must meet benchmark monitoring requirements.
  • Discharge a pollutant of concern at a level of concern directly into an impaired water body.

Submit your results for the monitoring period from Jan. 1, 2022, through Dec. 31, 2022.

Exceptions to Reporting in NetDMR

TCEQ may grant a temporary waiver from electronic reporting in limited cases for each authorization. To obtain a temporary waiver, contact the Stormwater Processing Center at 512-239-3700.

If you submit your results to TCEQ on paper forms without an electronic reporting waiver, we will return them to you.
