Upcoming Deadline for Stormwater Multi-Sector General Permit Facilities to Report in NetDMR

Facilities must report results through the NetDMR electronic reporting system if any of the following apply:

• Meet federal effluent limits within sectors A, C, D, E, J, O, or S. 
  • Part III, Section C.2., Table 3 of the MSGP ( TXR050000) lists all activities required to meet federal effluent limits.
• Meet numeric effluent limits for hazardous metals and must report if exceeding a permit limit in Part III, Section C.1, Table 1.
• Meet benchmark monitoring requirements, unless a waiver from Benchmark Monitoring was requested.
• Discharge a pollutant of concern at a level of concern directly into an impaired water body.

Facilities that meet any of the above criteria must report their results for the monitoring period of Jan. 1, 2024, through Dec. 31, 2024.

If you submit paper DMRs to TCEQ without an electronic reporting waiver, your submittal will not meet your reporting requirements.
