Long Term Control Plan

The goal of the Long Term Control Plan (LTCP) is to reduce overflows from combined sewer outfalls to improve water quality in the Missouri River and Papillion Creek. Under an agreement with the State of Nebraska, Omaha is committed to implementing the LTCP by October 2037.

The initial LTCP was developed, beginning in 2006 and approved in 2009. Implementation of the plan began in 2009.

  • Systemwide CSO controls

Additionally, the update focused on saving ratepayer funds while meeting the original objectives of the LTCP. The implementation schedule was revised to fit the rate model.

Regulations, Permit Requirements and Compliance

The City's requirement to address CSOs is based on the Clean Water Act of 1972, the CSO Control Policy of 1994, the subsequent Wet Weather Water Quality Act of 2002, and the City's Consent Order and discharge permit from the Nebraska Department of Environment and Energy (NDEE).

The criteria included the following:
