Home Browse Search

The Chair stated that all scenarios included onsite UAs and he expressed his preference not to use them, adding that they are not the most cost effective. Mr. Gregg questioned how the town would manage the islands, some of which are underwater in 100 year storm, without the use of I/As. The Chair noted that Mr. Lombardo used a rapid sand filter on the high point of Monomoscoy Island and a STEP collection system in his 1990 report for the Commission. I/A technology may need to be considered for locations where it would be difficult or costly to consider alternatives, or there may not be enough nitrogen to require its removal. The group also discussed the challenges of discharging under the pavement. The Chair noted that the Falmouth CWMP shows Seconsett Island tied into their sewer system. The group discussed the watershed areas and the Chair stated that there was just one sentinel station in Popponesset which is targeted, adding that the Mashpee River was a main reason for initiating the work of the Commission. Mr. Howes reminded the Commission that other criteria must be met beyond the sentinel station, to include Mashpee River, Shoestring Bay and Ockway Bay. All areas must work. The Chair will re-write the contract for Mr. Lombardo, deleting the two proposed studies and focusing on his participation as part of the scenario development team, including a maximum amount, and forward it to Mr. Berrelli for his review. The next meeting will be scheduled for Tuesday, February 9 at 4:30 pm. Meeting Minutes: Mr. Berrelli made a motion to approve the minutes of November 17,2009. Chairman Fudala seconded the motion. All voted unanimously. Status of Community Advisory committee Membership: A representative is still needed for Precinct S. Status of Discussions with Mashpee Water District, Selectmen and FinCom: Mr. Berrelli reported that there has been no change. Discussion of Town Meeting Article to Expand Sewer Commission: No news has been received from the Attorney General regarding the Town Meeting Article. CCWPC Items: Mr. Potamis attended a recent meeting and reported that the Collaborative was discussing the possibility of hiring a"circuit rider"wastewater consultant who would be available to each town on Cape Cod. The individual would be competitively bid and would assess whether or not a report was completed in accordance with generally accepted engineering standards. Additionally, a consultant would assist in putting together financial models to fund wastewater projects. The County Commissioners have supported hiring an independent consultant to work with the towns. The Chair also questioned whether or not per-foot pricing for sewer systems or step pumps versus grinder pumps were readily available. It was noted that the Regional Wastewater Management Plan and the Cape Cod Collaborative were working on putting together the construction costs of wastewater facilities and may be available in one month. Everyone agreed that recently collected bid prices are likely to be accurate. It was added that a standard formula exists utilizing the ENR index. 4
