INDIlM WITH COMITIONS, 8:00 PENINSUIA C UNCI L, IW, for a Determination of Applicability on the proposal of High Wood Nater Company to increase withdrawal of ground and surface water and the applicability under the Wetlands Protection Act and the Mashpee Bylaw at the well fields off Rock Landing Road. Mary Scanlan, Chairman of Fells Pond Committee, advised there is concern with Highwood Water Company's application to withdraw water and any possible alteration in the level ofthe grater in the pond. Mr. Sherman advised Tori F data had asked him to review the study and he agreed that Fells Pond could be affected. There are also other wetlands in the vicinity. It is an issue that does bear upon the Commission's responsibility. He suggested the fee should be waived. John Fitzsimons advised he received a copy of the application and comments were requested. He shared the concern that Fells Pond is fed by surface water. Studies show that amount of water to be pumped would affect ground water level. The pond is continuing to go down and down. 4 Mr, Sherman made comments to DEP Nater Resources Department that there would be change in the water table, Under the Wetlands Protection Act if changes are near a wetland, he feels there should be a filing, Dave Rich of Highwood Water Co. , stated a filing was made with DFP for the period of the next 25 gears, The baseline was established taking average flows from 1981 through 1985. The increase goes from .14M gallons t .92. It would bring the average daily withdrawal up to .92 in the year 2010. Pumping tests clone show 1365 gallons per minute, per day that would be pumping 1,960,000 gallons. They are asking to withdraw less than 49 of what this test was dome on. TheCommon- ,wealth of Massachusetts will be the body to permit any certain amount.

Rich advised Core of Depression means the area they will draw water from, it � does not mean a constant ground water level. change. Mr. Sherman pointed out it does not sac there isn't either, There are Wetlands within that circumference and the matter should be referred to DEP. He recomends positive determination. Mr. Homeyer asked if the town purchase of Highwood water would open it up to a greater draw. Mr. Rich believed the town had applied for a greater amount, however, if the town does purchase Highwood, the two permits will be lumped together. Mr. Sherman stated if a positive determination is oracle, Highwood Nater would have to file a Notice of Intent and furnish the Commission with details on the figures,
