Purpose To ensure that no unmitigated adverse impacts to water users or water-dependant natural resources occur as a result of a new large groundwater withdrawal established after July 1998. Adverse impacts are defined in RSA 485-C:21, V-c.
Applicability A large groundwater withdrawal permit is required for any withdrawal from groundwater of 57,600 gallons or more of water in any 24-hour period from a well or wells installed after July 1998 at a single property or place of business. Large groundwater withdrawals from new wells that replace a well or wells installed prior to August 1998 do not require a large groundwater withdrawal permit but do require approval from the Large Groundwater Withdrawal Permitting Program.
