FOR ES.1 Background The purpose of the Final Recommended Plan and Final Environmental Impact Report (FRP/FEIN) is to present the recommendations of this planning process to address the nitrogen Total Maximum Daily Loads (TMDLs) established for Popponesset Bay and Waquoit Bay's eastern basin, and to discuss the mitigation measures and implementation approach for Mashpee (and its neighboring communities within the project planning area) to address these needs as identified in previous documents. These recommendations as they relate to Mashpee will then be managed through the Mashpee Water and Sewer District and the Town of Mashpee. The Town of Mashpee initiated the process to develop a Watershed Nitrogen Management Plan (WNMP) in 1999 in order to address the nitrogen impacts to coastal embayments and to evaluate options for restoring those embayments through the development of a Comprehensive Wastewater Management Plan (CWMP). Because the contributing areas to the estuaries (watersheds) are shared by multiple towns, Mashpee's WNMP Project Planning Area (PPA) includes the Town of Mashpee and the portions of neighboring towns (Barnstable, Falmouth, and Sandwich) that fall within the Popponesset Bay and Waquoit Bay East Basin watersheds. The PPA is illustrated in Figure ES-1. The WNMP/CWMP is intended to provide an environmentally and economically sound plan for nitrogen reduction, wastewater treatment, and treated water recharge in the planning area. As stated previously, the CWMP is the culmination of multiple documents generated during the planning process. ES.2 MEPA Planning Documents In September of 2001, the Town of Mashpee, through the Mashpee Sewer Commission, entered into the MEPA process by filing their Environmental Notification Form (ENF) and MEPA Unit/Cape Cod Commission Joint Review Process Application Form. That document identified several major deliverables to be submitted for review through this process in addition to the Notice of Project Change submittals required due to the extended nature of this project. Those deliverables, which have been submitted, included: 1. Needs Assessment Report (NAR)—issued in April 2007 2. Technology Screening Report—issued in November 2007 3. Draft Alternative Scenarios Analysis and Site Evaluation Report—issued in March 2008 4. Two (2) Notices of Project Change (in 2007 and 2012) 5, Alternatives Screening Analysis Report (ASAR)—issued in August 2013 6. Draft Recommended Plan/Draft Environmental Impact Report (DRP/DEIR)—issued in June 2014 Following the submittal of the DRP/DEIR, MEPA issued their most recent certificate dated September 12, 2014, a copy of which is included in Appendix 1-1. That Appendix also includes the most recent response to comments. 8612001.4 Town of Mashpee Sewer Commission ES-2 Final Recommended Plan/Final Environmental Impact Report
