Mashpee Board of Sewer Commissioners <br /> Meeting Minutes <br /> December 15,2009 <br /> Mashpee Town Hall, Selectmen's Meeting Room <br /> Present: Chairman Tom Fudala <br /> Absent: Vice-Chairman Don Desmarais, Clerk Matt Berelli <br /> CALL TO ORDER <br /> The meeting was opened without a quorum by Chairman Tom Fudala at 7:10 p.m. No official <br /> business will be conducted, but, since representatives from UMass Dartmouth are in attendance, final <br /> results of their model runs for the five scenarios of Eastern Waquoit Bay will be presented for the <br /> benefit of the audience and for the record. <br /> AGENDA MMS <br /> Status of SMaST MEP (Massachusetts Estuary Project)Model Runs-Waquoit Bay Scenario <br /> Presentation by Ed Eichner <br /> Mr. Eichner, Senior Water Scientist at the Coastal Water Systems Program at University of <br /> Massachusetts in Dartmouth, presented the results of the Eastern Waquoit Bay scenario study using a <br /> PowerPoint presentation. A copy of the MEP Technical Memo is attached for the record. Mr. Eichner <br /> previously reported the results of the Popponesset Bay Scenarios at a Sewer Commission meeting on <br /> November 17, which he summarized for meeting attendees. <br /> Tasks <br /> Three tasks were undertaken to include the preparation of a unified database of revised land use <br /> information, use of the unified database to prepare nitrogen loads for each of the watershed wastewater <br /> scenarios and use of the information to link with the water quality model, comparing it to TMDLs for <br /> the MEP thresholds. <br /> MEP Watershed N Loading Module <br /> Mr. Eichner described maps of the two watersheds being considered, Eastern Waquoit Bay and <br /> Popponesset Bay. Mr. Eichner discussed their ability to conduct the analyses and comparison to the <br /> TMDLs due to the use of calibrated and validated models. The models were developed because land <br /> and water use information was available from Mashpee, Falmouth, Barnstable and Sandwich. The <br /> information was then used to develop nitrogen loads on a per parcel basis which was then fed into the <br /> water quality model to develop the TMDL for the systems. Once verified, the calibrated and validated <br /> model was used to evaluate the five scenarios. <br /> MEP Scenarios-Pre-assessment Background <br /> Mr. Eichner noted that the current five scenarios are the second set of scenarios. <br /> Wetland Restoration for Enhanced Nitrogen Removal <br /> Mr. Eichner described a scenario that considered an enhanced nitrogen attenuation that would remove <br /> nitrogen without requiring a wastewater treatment facility. The example Mr. Eichner presented <br /> includes use of abandoned cranberry bogs along the Santuit River. Mr. Eichner described the scenario <br /> as a"win-win" since a nitrogen load could be removed at a lower cost. <br />
