When to Consider Reassessing Your Technically Based Local Limits (TBLLs)
Consider reassessing your TBLLs if any of these conditions arise:
Your publicly-owned treatment works (POTW) expands
New commercial or industrial customers connect to your system
Existing commercial or industrial customers disconnect from your system
Your options for handling sewage sludge change
Monitoring data 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). In completing the form you may recognize situations that call for revisions.
