Stormwater Multi-Sector General Permit Sampling Results to be Submitted Electronically

Nov. 2018 - Multi-Sector General Permits (MSGPs), commonly referred to as Industrial Stormwater Permits, must now submit Discharge Monitoring Reports (DMRs) electronically using the NetDMR system.

Required samples must be collected before December 31, 2018, and the sampling results must be reported to the TCEQ by March 31, 2019, using the NetDMR electronic reporting system.

Permittees are required to submit MSGP DMRs for:

  • Facilities in sectors A, C, D, E, J, O, and S; and
  • Facilities in all sectors that are required to meet numeric effluent limits for hazardous metals where sample results indicate an exceedance of any constituent listed.

If you are required to submit MSGP DMRs and you are unable to report electronically, you can submit a Request for Electronic Reporting Waiver form (TCEQ-20754). The TCEQ may grant a Temporary Waiver from the electronic reporting rule in limited cases. A separate waiver form is required for each authorization. Waiver forms may be obtained by contacting the Stormwater Processing Center at 512-239-3700.

To submit your DMRs electronically, you must access the NetDMR system through the EPA’s Central Data Exchange (CDX). Please visit the NetDMR Support Portal webpageExit the TCEQ to find information on how to create an account. Facilities can also contact the TCEQ’s NetDMR help line at 1-855-906-MSGP (6747) to receive assistance unlocking an account, filling out a DMR, or understanding the permit requirements.

The next NetDMR training session is scheduled for Wednesday, December 5, 2018, 12:00 pm - 2:00 pm (CST). To register for the training visit: the TCEQ
