Title
Consider an ordinance repealing and replacing in its entirety, Chapter 42, Article IV, Code of Ordinances (2018 Edition), regarding the City's Pretreatment Program. (First Reading)*
Body
The Environmental Services Division manages the Industrial Pretreatment Program in accordance with the Clean Water Act and 40 Code of Federal Regulations Part 403. The purpose of the program is to protect the wastewater treatment process by regulating non-domestic wastewater discharge. Fifteen significant industrial users are regulated by the City, seven of which are categorical industrial users. In addition, four general industrial users are regulated by the City.
Elements of the Industrial Pretreatment Program include the ordinance, permits, inspection and sampling, technically based local limits (TBLLs) and enforcement. The ordinance enables the City to enforce the required pretreatment standard on the industrial users. Permits regulate the pollutant discharge of industrial users to the Wastewater Treatment Plant. Inspection and sampling verify that the industrial users are complying and meeting all relevant pretreatment standards. TBLLs are quantitative limits on wastewater discharges applicable to all users. Lastly, the program develops and enforces local limits to provide site-specific protection for the Wastewater Treatment Plant and the receiving waters.
The Texas Commission on Environmental Quality (TCEQ) is requiring the City to modify its Industrial Pretreatment Program ordinance due to requirements set forth in the Environmental Protection Agency’s (EPA) streamlining rule. The EPA streamlined existing regulations to give more flexibility to the Control Authority to enforce environmental protection. Changes include expanded sampling techniques, clarification of significant noncompliance, flexibility in determining categorical pollutant limits, and better consistency with the National Pollutant Discharge Elimination System (NPDES) regulations.
