GREER TOYOTA ~~~l
INACTIVE HAZARDOUS WASTE SITE (#3140~j\.'l,~l.lR
TOWN OF WAPPINGER, DUTCHESS COUNTY UST/CECOUAT
The New York State Department of Environmental Conservation (NYSDEC) announces that the printed Record
of Decision (ROD) for the Greer Toyota Inactive Hazardous Waste Disposal Site # 314088, Town of Wappinger,
Dutchess County is available. The ROD presents the selected remedy for the Greer Toyota site and the rationale
for the chosen remedy.
NYSDEC held a public meeting on March 19,2002, presenting the Proposed Remedial Action Plan for the Greer
Toyota site and receiving public comments on the proposal. The comments received at this meeting and during
the public comment period (February 26, 2002 through March 27, 2002) were considered, along with the
administrative record for the site in preparing the final ROD. The ROD also contains a Responsiveness Summary
addressing the public comments received.
The chosen remedial action plan described in the ROD includes:
. A remedial design program to verify the components of the conceptual design and provide the details
necessary for the construction, operation and maintenance, and monitoring of the remedial program.
. Installation of a soil vapor extraction (SVE) system including a positive displacement type blower, two
vertical vapor extraction wells, a vapor treatment system, and required system controls. Soil testing will
be conducted to monitor the efficiency of the system.
. Delivery of hydrogen release compounds (HRC) and oxygen release compounds (ORC) to contaminated
soil and groundwater to destroy the contaminants through rapid biological degradation. If, after
evaluation of the SVE phase it is deemed necessary, HRCIORC \vill be introduced to the soil and
groundwater in the source area through existing wells and piping on the site. A soil and groundwater
monitoring plan including site reviews will be completed.
. Maintenance and monitoring of existing treatment (carbon filters) on impacted private supply wells until
one half the drinking water standards are met for four consecutive quarterly sampling events.
. Private well sampling survey near the site to confirm all impacted wells are known by the NYSDEC and
NYSDOH. If wells are found to be impacted by site related contaminants Greer Toyota shall install
carbon filters and maintain them on a quarterly basis.
. Continued maintenance and improvements to the site that will reduce infiltration into the source region.
. Annual certification to the NYSDEC by property owner that the site is in compliance with engineering
controls outlined in the ROD.
