transparent Long Term Control Plans

The Long Term Control Plan (LTCP) is a system wide evaluation of the sewage infrastructure, and the hydraulic relationship between the sewers, precipitation, treatment capacity and overflows. As part of the LTCP, the permittee must evaluate alternatives that will reduce or eliminate the discharges, and develop a plan and implementation schedule to do so. LTCPs are created to identify the most cost-effective manner to regulate CSOs to meet water quality standards. The permittee must establish a public participation process that actively involves the affected public throughout the process.

The National CSO Policy [PDF, 1517 kb] identifies the following essential elements of a LTCP:
  1. Characterization, monitoring, and modeling activities as the basis for selection and design of effective CSO controls;
  2. A public participation process that actively involves the affected public in the decision-making to select long-term CSO controls;
  3. Consideration of sensitive areas as the highest priority for controlling overflows;
  4. Evaluation of alternatives that will enable the permittee, in consultation with the National Pollution Discharge Elimination System permitting authority, Water Quality Standards authority, and the public, to select CSO controls that will meet CWA requirements;
  5. Cost/performance considerations to demonstrate the relationships among a comprehensive set of reasonable control alternatives;
  6. Operational plan revisions to include agreed-upon long-term CSO controls;
  7. Maximization of treatment at the existing Publically Owned Treatment Works treatment plant for wet weather flows;
  8. An implementation schedule for CSO controls; and
  9. A post-construction compliance monitoring program adequate to verify compliance with water quality-based CWA requirements and ascertain the effectiveness of CSO controls.

USEPA's Guidance for Long-Term Control Plan [PDF, 14703 kb] provides guidance on the development and implementation of a LTCP.
