When to Consider Reassessing Your Technically Based Local Limits (TBLLs)
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 Form (TCEQ-20221). (Help with PDF.) In completing the form you may recognize situations that call for revisions to the TBLLs.
