costs and prepare a recommended plan for Mashpee to move forward. The outline established for the <br /> MEPA process includes developing a needs assessment report,technology screenings, scenario analyses, <br /> site evaluations, alternative screening analyses report, preparing conceptual and preliminary designs, cost <br /> estimating, recommending a plan and preparing an environmental impact report related to the plan. A <br /> series of reports have been prepared since 2005. Prepared reports have been provided to Committee <br /> members on a disk from Chairman Fudala. <br /> Regarding the needs assessment,the planning area was divided into smaller areas to better address the <br /> project. For the planning areas outside of Mashpee, sub-watersheds developed by MEP were utilized and <br /> planning zones in Mashpee were developed by the Planning Department. Among the parcels, 701/o are in <br /> Mashpee, 201/6 in Sandwich and 5%each are in Barnstable and Falmouth. The report includes existing <br /> information, data review, regulatory requirements, summary of Estuaries Project results, existing and <br /> future conditions and establishing priority areas_ Additional information includes water quality <br /> information, sensitive areas and ACECs. Maps were developed to include contribution areas to wells <br /> (Zone 2), vernal pools, natural habitats and wetlands. Existing treatment plants were also considered, one <br /> located in Sandwich and 8 located in Mashpee. The design flow for the facilities has been permitted for a <br /> range of 18,000-300,000 gpd(gallons per day)_ Mr. Gregg referenced the locations of the plant locations <br /> throughout the Town's watersheds that serve a variety of uses including residential, commercial and <br /> schools. Mr. Gregg discussed the method used to calculate existing and future conditions. Non <br /> wastewater flows were determined through the use of MEP's land based fertilizer use, pavement and roof <br /> runoff and precipitation to calculate the loads to the system_ Of the controlled sources, 801/o-901/6 of the <br /> load is wastewater related. GHD identified how to apply the accumulated information and where to begin <br /> in Mashpee. Various factors were considered such as MEP findings, issues of seasonality, Zone 2 issues <br /> and Mashpee River and Santuit Pond issues. A matrix was developed along with a map to identify the <br /> priority areas_ <br /> Once TMDLs became available, GHD needed to develop an approach to meet the targets using the five <br /> scenarios which were run by MEP. <br /> 1-All treatment facilities would remain as is; buildout would occur to permitted amounts and new <br /> facilities built <br /> 2-Current facilities would be upgraded and expanded; new facilities added <br /> 3-Lombardo Nitrex scenario using cluster approach and on-site systems <br /> 4-"Fair share" <br /> 5-Centralized facility but working cooperatively with adjacent towns <br /> The MEP evaluations determined that each scenario had its merits but noted that the most effective <br /> method ensures that effluent be treated outside of the watersheds or directed into less sensitive <br /> watersheds. <br /> h m <br /> GHD also evaluated various discharge sites including Heritage Park ball field, As u et Road, Transfer <br /> Station property, high school ball fields, Keeter Property, New Seabury Golf Course, Golden Triangle in <br /> Sandwich and property off of Olde Barnstable Road. Some sites would allow wastewater treatment only <br /> or discharge only depending upon the location. Some sites had issues and required re-evaluation. New <br /> 5 <br />
