Title
Consider an ordinance amending the City of Keller Code of Ordinances by amending Chapter 19, Water and Sewers; by repealing Articles V. - Wastewater Pretreatment Program, in its entirety; and by adding a new Article V, Wastewater Pretreatment Program; providing a severability clause; establishing an effective date; and authorizing publication.
Action Requested:
Conduct a public hearing and consider an ordinance update of Chapter 19, Article V of Keller’s Code of Ordinances; Wastewater Pretreatment Program.
Background:
The City of Keller contracts with the Trinity River Authority (TRA) to treat all wastewater from the city at its Central Regional Wastewater System and Denton Creek Regional Wastewater System as one of its many wholesale customers. As a wholesale customer of TRA, the City of Keller is required to formally adopt industrial waste and pollution pretreatment regulations that meet or exceeds the requirements set forth by the Clean Water Act (33 United States Code §§ 1251 et seq) and the General Pretreatment Regulations (40 Code of Federal Regulations Part 403) 40 CFR 403)).
In summary, these regulations require that the City of Keller have pretreatment regulations in place sufficient to avoid adverse effect to public health, safety and general welfare through the adoption of Technically Based Local Limits (TBLL) for Wastewater Discharges set forth by the National Pollutant Discharge Elimination System (NPDES) and the Texas Commission of Environmental Quality (TCEQ).
The City currently has Ordinance No. 1142 in place, last updated in 2003, that reflects the industry standards set at the time. However, in accordance with NPDES and TCEQ guidance, TRA has updated these regulations and requires that local ordinances be updated to reflect compliance with the latest standards as well. Changes to the ordinance include new abbreviations and definitions; prohibited discharges expanded to include new limits; along with new Best Management Practices (BMP) and penalty language to be implemented; and clauses for consent orders, severability and the repeal of the Ordinance No. 1142 for replacement with the current draft ordinance.
TRA requires evidence be submitted that applicable regulations have been adopted reflecting these new program changes by October 1, 2024. Failure to adopt by the required date will result in suspension of Keller’s contract with TRA.
Once the ordinance has been updated, staff will send notification to TRA so that the City can continue to participate in the water and waste pretreatment program.
Citizen Input/Board Review:
Not Applicable.
Council Action:
Staff recommends approval of the proposed ordinance update.
