Nine Minimum Controls
As a city utility department, our CSO Long Term Control Plan Update is required to meet the regulations set forth by the National CSO Control Policy which consist of the following nine elements:
- Characterization, monitoring, and modeling of the combined sewer system as the basis for selection and design of effective CSO controls
- A public participation process that actively involves the affected public in the decision making to select long-term CSO controls
- Consideration of sensitive areas as the highest priority for controlling overflows
- Operational plan revisions to include agreed-upon long-term CSO controls
- Evaluation of alternatives that will enable the permittee, in consultation with the National Pollutant Discharge Elimination System permitting authority, Water Quality Standards authority, and the public, to select CSO controls that will meet the Clean Water Act requirements
- Cost/performance considerations to demonstrate the relationships among a comprehensive set of reasonable control strategies
- Maximization of treatment at the existing wastewater treatment plant for wet weather flows
- An implementation schedule for CSO controls
- A post-construction compliance monitoring program adequate to verify compliance with water quality-based CWA requirements and to achieve the effectiveness of CSO controls.
