Use the appropriate discharge monitoring report (DMRs) listed below if you are covered under the Multi-Sector General Permit (TXR050000) and are required to record analytical data for effluent monitoring. Keep these monitoring results on-site with the storm water pollution prevention plan. Some dischargers will also need to submit their forms, as described below, under When do DMRs need to be submitted to TCEQ?

• Hazardous Metals DMR (Inland Waters) (All Sectors)

• Hazardous Metals DMR (Tidal Waters) (All Sectors)

• Sector A DMR (Wet decking)

• Sector C DMR (Fertilizer manufacturing)

• Sector D DMR (Paving and roofing materials manufacturing)

• Sector E DMR (Cement manufacturing)

• Sector J DMR (Mine dewatering)

• Sector O DMR (Coal pile storage)

When do DMRs need to be submitted to TCEQ?

DMRs are to be submitted to TCEQ by March 31 of each year in the following cases:

1. Any non-compliance with an effluent limit for any of the hazardous metals required in Part III.D.1 of this permit, or for TSS and pH as required in Part III.D.2 of this permit, shall be recorded on a DMR and reported at a frequency of once per year.

2. All results of sampling for effluent limits in accordance with Part V of the permit (Sector-specific requirements in Sectors A, C, D, E, J, or O) must be submitted to the TCEQ.

Where are the DMRs to be mailed?

TCEQ, Information Resources Division, MC-213
P.O. Box 13087
Austin, TX 78711-3087

What about Benchmark Monitoring?

Not all sectors are required to conduct benchmark monitoring. Those sectors which are required to conduct benchmark monitoring are listed in Part IV Section B of the Multi-Sector Industrial General Permit for Storm Water. For more information, refer to the Benchmark Monitoring Data Analyses webpage.

For more information, refer to General Permit TXR050000 and look at the Small Business and Local Government Assistance sampling guide.
