When to Consider Reassessing Your Technically Based Local Limits (TBLLs)

Conditions under which technically-based local limits are reassessed.

Whenever any of these conditions arise, you should consider reassessing your TBLLs:

  • Expansion of your publicly-owned treatment works (POTW)

  • New commercial or industrial customers connect to your system

  • Existing commercial or industrial customers disconnect from your system

  • Changes in your options for handling sewage sludge

  • Monitoring data that shows noteworthy variations of pollutants of concern from previous levels in your POTW's influent, effluent, or both

If you are not certain whether your adopted TBLLs need to be revised, complete the TBLLs Reassessment FormAdobe Acrobat PDF Document (TCEQ-20221). (Help with PDF.) In completing the form you may recognize situations that call for revisions to the TBLLs.
