^ HOPEWELL PRECISION AREA GROUNDWATER SUPERFUND SITE
*L PRCftf- HOPEWELL JUNCTION, DUTCHESS COUNTY, NEW YORK
The U.S. Environmental Protection Agency (EPA) announces the opening of a 30-day comment period on the Proposed Plan and
preferred cleanup alternative to address contamination at the Hopewell Precision Area Groundwater Superfund site in Hopewell
Junction, Dutchess County, New York. The comment period begins on July 31,2009 and ends on August 30,2009. As part of the
public comment period, EPA will hold a Public Meeting on Tuesday, August 11,2009 at 7:00 PM at the Gayhead Elementary
School, 15 Entry Road, Hopewell Junction, New York 12533. To learn more about the meeting you can contact Ms. Cecilia Echols,

www.epa.gov/region2/superfund/npl/hopewell.
The Hopewell Precision Area Groundwater Superfund site is listed on the Superfund National Priorities List. EPA recently concluded a
remedial investigation/feasibility study (RI/FS), Operable Unit (OU) 1, for the site to assess the nature and extent of contamination in
site media and to evaluate cleanup alternatives for the site. Based upon the results of this OU 1, EPA has prepared a Proposed Plan
which describes the findings of the remedial investigation and potential remedy evaluations detailed in the feasibility study and provides
the rationale for recommending the preferred cleanup alternative.
The preferred cleanup alternatives is comprised of:
•An investigation and pilot study of aerobic cometabolic bioremediation (ACB) to determine the rate and the parameters for
full-scale enhancement of aerobic cometabolic degradation in the aquifer.
•Remedial design and full-scale enhancement implementation of ACB remedy to achieve restoration of the groundwater to
drinking water standards within a reasonable time period.
•Long-term monitoring to track the movement of and changes in the contaminated groundwater plume.
•Annual vapor monitoring of homes determined to be "at risk" for vapor intrusion and implementation of vapor mitigation
systems in houses that exceed protective levels, based on changes in the plume.
During the August 11, 2009 Public Meeting, EPA representatives will be available to further elaborate on the reasons for
recommending the preferred cleanup alternative for OU 1 and public comments will be received.
The RI Report, FS Report, Risk Assessment, Proposed Plan and other site-related documents are available for public review at the
information repositories established for the site at the following locations:

community. It is important to note that although EPA has identified a preferred cleanup alternative for the site, no final decision
will be made until EPA has considered all public comments received during the public comment period. EPA will summarize these
comments along with EPA's responses in a Responsiveness Summary, which will be included in the Administrative Record file as part
