Unilateral Administrative Order Issued Regarding Mottolo Superfund Site in Raymond, N.H. (NH)
(Boston, Mass. – Nov. 19,
2010) – EPA has signed a Unilateral Administrative Order,
requiring Gillingham Road, LLC to refrain from installing any new
groundwater wells or pumping any currently installed groundwater
wells on property located northwest of the Mottolo Pig Farm
Superfund Site in Raymond, N.H. The UAO serves to prevent the
release of hazardous substances because the property is located in
an area where new groundwater use is likely to draw site
contamination into new or existing wells.
The order follows a Record of Decision Amendment issued by EPA on
Sept. 22, 2010, which will add an extension of the Town of Raymond
public water supply main approximately two miles to provide public
water to approximately 25 residences.
The Mottolo Pig Farm, previously owned and operated by Richard
Mottolo, has been on EPA’s Superfund list since 1987
following completion of a removal action on site. The pig farm was
used as a disposal location by the owner until 1979, who disposed
of drums and pails containing hazardous waste into a one-quarter
acre depression at the site. Work by EPA and the N.H. Dept. of
Environmental Services (NHDES) has also included several additional
cleanup actions as well as long term water monitoring on and around
the site. Recent results of the groundwater monitoring found
elevated levels of trichloroethylene (TCE) and arsenic in some
residential drinking wells. The September Record of Decision
Amendment served to address continuing water contamination issues
in these residential wells.
Gillingham Road, LLC is the owner of property located on Blueberry
Hill Road near the site. The property has been subdivided for
residential development of 35 lots. Despite prior communications
from EPA and NHDES notifying Gillingham Road, LLC that use of the
groundwater under the property would likely cause contaminated
groundwater to migrate toward the property, Gillingham Road, LLC
has proceeded to install wells on the property and purge them for
testing. Prior to the effective date of the Order, Gillingham Road,
LLC will have an opportunity to request a conference with EPA, on
any matter pertinent to the Order.
