6 Board of Selectmen Minutes July 10, 2006 APPOINTMENTS AND HEARINGS: Sewer Commission—Status Update:(continued) Scenario 2a and 2b consider the use of on-site denitrifying septic systems for all existing and future development in the Popponesset Bay watershed except those served by private wastewater treatment facilities. It was noted the Popponesset Bay Pilot Project considers the Town's of Mashpee, Barnstable and Sandwich. The Town of Mashpee is noted to add 740%)to the nitrogen loading. A timeline of the Mashpee Watershed Nitrogen Management Plan was reviewed. In November of 2006,the report associated to the Development and Evaluation of Alternate Scenarios should be complete. The Conceptual Design and Cost Estimates for the Selected Scenarios in Phase V are anticipated to be complete in January of 2007. The Recommended Plan, Phase VI of the project proposal is projected in April of 2007. The r-- Selectmen will continue to be updated with respect to this regard. • Waterways Commission: Mashpee River Dredging Update: Jim Hanks, Waterways Commission Chair was present to discuss the results of the sediment resistivity analysis. The results were outlined in a memorandum dated July 2, 2006 addressed to the Board of Selectmen. Upon examining the values,the Town Transfer Station,upland disposal was not considered a viable option as a result of the measured salinity. It was noted that the use of hydraulic dredging as the slurry would contain 90%brackish water before dewatering. After it is dried, it would have the same or higher conductivity as the top samples and therefore be unsuitable. The Waterways Commission will continue to review options for dredging disposal. This would include the option to build salt marsh islands. Mr. Hanks is expected to conduct a strategy session with Dr. Brian Howes later this month. It is hopeful that recommendations will be brought to the Selectmen in mid-September.
