Galligan, Mayor City of Jeffersonville City Hall 500 Quartermaster Court Jeffersonville, Indiana 47130 Re: Long Term Control Platt Approval City of Jeffersonville Consent Decree #4209- CV- 0125DFH -WGIl NPOES Permit No. 1N0023302 Clark County Dear Mayor Galligan: The Indiana Department of Environmental Management (IDEM) and the U.S. Environmental Protection Agency (EPA) have conducted a substantive review of the City of Jeffersonville's (the City) CSO Long Term Control Plan (LTCP). The United States, on behalf of the United States Environmental Protection Agency, and the State of Indiana, on behalf of IDEM. filed a complaint against the City in connection with the City's operation of its municipal wastewater and sewer system. Concurrent with the filing of the Complaint, the United States lodged with the Court a proposed Consent Decree that has been entered into by the United States, the State of Indiana, and the City of Jeffersonville. The Consent Decree was entered by the Court on November 2A. 2009, as United States and State of Indiana v. City of Jeffersonville. #4:09•CV -0 125DFH -WGH. The Consent Decree requires the City to complete development of its LTCP. Once approved by EPA and IDEM, the LTCP is incorporated into the Consent Decree. As a function of the LTCP development process, the City of Jeffersonville performed an evaluation of alternatives for CSO control. The Jeffersonville Sewer Board passed a motion to recommend Alternative 4 (near surface storage). along with Control Scenario 61 (4 -month control design level for Cane Run and 6 -month control design levet for the Ohio River). The City's proposed LTCP alternative is identified in detail within Chapter 10 of the LTCP submitted by the City on March 31, 2010. specifically within Tables 10.02.1, 10.02 -2 and 10.02 -3. The proposed alternative, once implemented, is expected to result in no more than one (1) untreated overflow to the Ohio River in a typical year, and no more than three (3) untreated overflows to Cane Run in a typical year, respectively. Following BEM and EPA approval, the LTCP proposes a 15 -year implementation schedule for the proposcd alternative, at an estimated total capital cost of approximately S143,000.000. Ikem t'uprr ® An Equal Oppa:lunity limployer 1n:a :rR M,Y:•. L1 • The Honorable Thomas R. Galligan, Mayor Page 2 Although no specific green infrastructure projects are included in the proposed alternative, the City intends to continuously evaluate green infrastructure projects throughout the LTCP implementation schedule. The City expects CSO events will continue to occur during stoma that exceed the design and performance criteria proposed in the LTCP. Therefore, a Use Attainability Analysis (UAA), as provided • for in both federal and state law, would need to be developed and submitted to IDEM prior to full implementation of the LTCP to avoid water quality violations at that time. A UAA is a structured scientific assessment that provides the technical basis for removing designated uses applied to surface waters where k is shown that the designated use is not an existing use and that the attainment of the designated use is not feasible. The UAA must contain the technical and financial justification for changing the designated recreational use for CSO impacted waters from "full body contact" to the "Combined Sewer Overflow (CSO) wet weather limited use" subcategory of Indiana's recreational use designation as provided in 1C 13- 183.2.5. The City of Jelfersonville's LTCP submitted on March 31, 2010, as amended by its submissions including the City's CSO LTCP's Section 10, Recommended Plan & Implementation Schedule. as revised November 10, 2010; the City's CSO Operational Plan (CSOOP). as updated December 1.2010, and the CSO LTCP's Section 11, Posh Construction Compliance Monitoring, as revised April 4, 2011, is hereby approved by IDEM and EPA. Pursuant to paragraph 96 of the Consent Decree. the City shall proceed to implement its LTCP within fourteen (14) days of this approval. This LTCP as approved must be incorporated into the City's NPDES permit No. 1N0023302. The LTCP implementation schedule is enforceable in accordance with the City's NPDES permit and the Consent Decree.
