Development of a Combined Sewer Overflow Long-Term Control Plan for the City of Omaha, Nebraska
Abstract:The City received its first National Pollutant Discharge Elimination System (NPDES) permit fortheir combined sewer system (CSS) in October 2002. The permit required the City to continue to develop and implement its Nine Minimum Controls Plan (NMCP) and to develop a Long Term Control Plan (LTCP). Since that time the City has been complying with the submittal requirements included in the permit, and working toward the development of a LTCP. In 2005, the Nebraska Department of Environment (NDEQ) notified the City of the requirement for the City to submit a “Substantively Complete” LTCP by October 2007, Final LTCP plan by October 2009, and to construct the LTCP controls by 2024. NDEQ stated that these dates would be included under an “enforcement mechanism” such as a Consent Order. To meet the aggressive planning deadlines, the City hired a Program Management Team (PMT) to lead a team of consultants in evaluating control alternatives and selecting controls for implementation. This paper summarizes the City's approach to developing the LTCP.
