Update 8/28/2019: As of Monday, August 26, Pinetree Power has withdrawn the groundwater discharge permit applications: https://www4.des.state.nh.us/IISProxy/IISProxy.dll?ContentId=4801286


Please find below letters detailing concerns of the Ossipee Aquifer Advisory Committee and Green Mountain Conservation Group about a proposed groundwater discharge permit that has been submitted to NH Department of Environmental Services (NHDES) by Pinetree Power of Tamworth, NH.  The proposed discharge will have significant deleterious impacts to drinking water in the pristine Ossipee Aquifer and over 20 years of efforts to protect this critically important drinking water source. Also below are links to more information, including the permit application to NHDES, the hydraulic test report, and more.
