How does the CWA affect wastewater collection and pretreatment?
Both of these programs have requirements relating to the CWA and the City s NPDES permit. Discharge of untreated wastewater from the collection system is considered a discharge violation and these requirements are covered in the City s NPDES permit. The pretreatment program has a section in the CWA that specifically lists all the requirements for the program and the industries it must monitor, sample and inspect. The City s NPDES permit also has a pretreatment section.
