TPDES Permit: Pretreatment Requirements
The Contributing Industries and Pretreatment Requirements section of the Texas Pollutant Discharge Elimination System (TPDES) permit includes pretreatment requirements for all publicly-owned treatment works (POTWs) regardless of whether or not the POTW has an approved TPDES pretreatment program. If you do not have an approved pretreatment program the permit includes specific prohibitions and notification requirements. If you do have an approved program, the pretreatment requirements in the permit are based on whether or not the POTW has significant industrial users discharging wastewater to the sewer system.
A POTW not required to implement an approved pretreatment program should consider developing a local pretreatment program in order to:
Protect the receiving stream
Correct existing problems at the POTW and the collection system
Prevent potential problems at the POTW and the collection system
Increase sludge disposal options
Protect the POTW and its personnel
If You Discover Changes
Your permit also requires you to notify us whenever you become aware of a substantial change in the characteristics of your plant's influent.
Even though your permit does not require you to establish an approved pretreatment program, it is still a good idea to have a local pretreatment program that has the key elements of an approved program.
