The city is proposing modifications to the enforcement response plan, local limits and Division 2, Wastewater Pretreatment Regulations, including the following changes:
- Updated regulations at Section 24-133 Definitions by removing a portion of the description for the Superintendent and replacing the legal authority to refer to the Public Works Director.
- After conducting a detailed local limit analysis that is part of this program modification, eliminated the uniform concentrations previously adopted as local limits in Section 24-137 and alternatively specified prohibited mass limits (less stringent maximum allowable industrial loading (MAILs)) in 24-134(c).
- In Section 24-176 (6), updated the definition of significant noncompliance for late reporting from 30 days to 45 days.
- Modified Section 24-134 (a) (17), which defines prohibitions for animal fats, oil and grease, from 100 mg/L to 150 mg/L for total fats, oil & grease (as measured by EPA approved methods for total hexane extractable materials.
The pretreatment program changes were designated substantial modifications because the changes could have a significant impact on the operation of the program, pursuant to 40 CFR 403.18(b)(7).
