In compliance with Public Laws 84-660 and 92-500 of the Water Pollution Control Act and amendments hereto, these regulations adopt and use as a guide the national pretreatment standards and the Environmental Protection Agency’s (EPA) pretreatment guidelines. The City recognizes that in some cases these pretreatment standards may not be sufficient to protect the operation of its treatment works, or to allow it to comply with the terms of its NPDES Permit. In such cases, the City reserves the right to impose more stringent standards than those specified in the EPA regulations.
