NOTICE IS HEREBY GIVEN THAT: The New Hampshire Department of Environmental Services (Department) has issued Groundwater Management Permit #GWP-_________-A-001 (“Permit”) to [Permittee]. Pursuant to Env-Or 607.09(a) this notice is recorded for each property located within the groundwater management zone identified in the Permit at the Registry of Deeds for the county in which the property is located.

The Permit establishes a Groundwater Management Zone (“GMZ”), an area within which groundwater use must be controlled and monitored due to the presence of groundwater contaminants that exceed the State’s Ambient Groundwater Quality Standards (“AGQS”). The Permit may include conditions to and restrictions upon the use of the properties within the GMZ, including restrictions on the use of groundwater.

The Permit was issued on [Date] and expires on [Date], unless renewed for subsequent five-year period(s). This Notice will remain in effect until such time as the AGQS are restored within the GMZ and the Department issues a Release of Recordation to the Permittee. The Permit is available for review at the New Hampshire Department of Environmental Services, 29 Hazen Drive, Concord, NH 03301 or can be viewed by searching under our OneStop Data Retrieval Site at http://www2.des.nh.gov/OneStop/ORCB_Query.aspx?Project+CCST .

The following properties are located within the GMZ:
