DES Reaches Agreement with Liberty Utilities on Lower Liberty Hill Road, Gilford Cleanup Plan

Concord, NH – The New Hampshire Department of Environmental Services announced today that it is has reached agreement with EnergyNorth Natural Gas, Inc. d/b/a Liberty Utilities (formerly National Grid) on a cleanup plan for the Lower Liberty Hill Road site in Gilford. The selected cleanup plan consists of the excavation of soil with coal tar impacts that serve as a source of groundwater contamination, off-site treatment of impacted soils, and site restoration.

In 2004, DES and EnergyNorth learned that a gravel pit located along the lower portion of Liberty Hill Road was used to dispose of waste coal tar from the former Laconia manufactured gas plant in the 1950s. From 2004 thru the present, EnergyNorth (whose predecessor company operated and dismantled the plant) has conducted site investigation and monitoring under the oversight of DES. After several previous proposed cleanup plans were deemed unacceptable, EnergyNorth has submitted a cleanup plan that meets the State’s criteria for approval.

DES will hold a public information meeting to discuss the status of the site and actions for moving forward with the cleanup plan. This meeting will be held at 7 pm, Wednesday, January 23, 2013, at the Gilford Public Library – Meeting Room, 31 Potter Hill Road.

The Conceptual Remedial Design Report is available via DES’ One Stop website at The report is also available at the Gilford Public Library. For more information regarding the cleanup plan, please contact John Regan, P.G. at (603) 271-3744 or Michael McCluskey, P.E. at (603) 271-2183.
