Site Description 	
Since 1956, the Vi-acre Mercury Refining, Inc. site, located in Colonie, New York, has been used for
reclaiming mercury from batteries. The site lies in a light industrial and commercial area. The closest
residents are about 1/4 mile to the north of the site. Approximately 20,000 people live within a
1 '/2-mile radius of the property; 100,000 live within 3 miles. Local surface water is used for
recreation and as a drinking water supply. The nearest downstream supply intake is 1 mile from the
site. A tributary to Patroons Creek, which flows to the Hudson River, runs next to the site. Operators
dumped waste batteries behind an on-site furnace building until 1980, when these wastes were stored
in drums on wooden pallets on paved areas of the site. Tests in the early 1980s indicated that waste
was at least 3 feet below the ground surface. The State's Fish and Wildlife Service tested soil in this
area in the early 1980s and discovered high levels of poly chlorinated biphenyls (PCBs) and mercury
in soils and stream sediments. PCBs were found in the insulation of some of the incoming waste
material the Company accepted. The site has been partially remediated and the waste disposal
methods of the Company have improved. In 1998, Mercury Refining ceased its mercury reclamation
activity at the site. Currently, the site serves as a transfer facility for mercury bearing material,
which is shipped off-site for reclamation at another location.
Site Responsibility: This site is being addressed through
federal and potentially responsible party
actions.

Threats and Contaminants
zn
Groundwater, surface water, sediments, and soil are contaminated with heavy metals
including mercury, zinc and lead. The soils were also contaminated with PCBs.
Although contaminated soil has been excavated and moved off-site, additional
contamination remains. The risks to personal health may include eating contaminated
fish. Although the groundwater is contaminated, there are currently no known domestic
uses of groundwater within the area, so it is unlikely that people would be directly
exposed to groundwater contaminants.
Cleanup Approach 	
The New York State Department of Environmental Conservation (NYSDEC) issued Mercury
Refining a hazardous waste corrective action permit on December 31, 1996. The permit required the
Company to remove contaminated soil under an old furnace building located on-site and perform
long-term monitoring of on-site soil and groundwater and off-site soil and sediments in Patroons
Creek. Any groundwater, soil or stream sediments which were found to be contaminated were to be
remediated. Due to Mercury Refining's failure to complete these actions, the NYSDEC requested
EPA to assume the role of lead agency in November 1999. EPA is completing remediation of the
site using its Superfund authority. In May 2000, EPA offered Mercury Refining the opportunity to
perform a remedial investigation and feasibility study (RI/FS) of the site. However, Mercury
Refining indicated that it does not have the financial ability to do the study. The RI/FS, therefore, is
presently being done by EPA. The field work portion of the RI will be completed in May 2002. EPA
plans to complete the RI/FS and issue a determination on a final clean-up remedy by the winter of
2003.
Response Action Status 	
Entire Site: Under a 1985 State Consent Order, Mercury Refining excavated and
removed about 2,100 cubic yards of mercury-contaminated soil and debris and 300 cubic
yards of PCB-contaminated soil. Contaminated soil was found beneath the furnace
building and was left in place after being sealed with plastic sheets. The Site was regraded with clean
fill and capped to keep rainwater from spreading any remaining contaminants. The State issued
another Consent Order on February 8, 1993, which required removal of the contaminated soil
under the furnace building and long-term monitoring of on-site soil and groundwater and off-site
soil and sediments in Patroons Creek. In December 1996, the NYSDEC issued to the Company
a hazardous waste corrective action permit for the purpose of controlling the generation and
storage of hazardous waste on-site and for investigating and remediating on- and off-site
contamination. The Company failed to comply with the 1993 Order and the permit. After

unsuccessfully working to resolve the matter with the Company, the NYSDEC relinquished its
position as lead agency to EPA. EPA is now addressing remediation of the site under the
Superfund Program.
Site Facts: In 1985, a State Consent Order required the Company to conduct cleanup activities at
the site. In 1989, the NYSDEC issued a Consent Order that required Mercury Refining to curtail any
further chemical releases from plant operations to the environment. On February 8, 1993, the
NYSDEC issued the Company another Consent Order, which required cleanup of contaminated soils
and long-term monitoring of on-site groundwater and soil and off-site soil and stream sediments in
Patroons Creek. In December 1996, the NYSDEC issued a hazardous waste corrective action permit,
which required the cleanup of any remaining contamination. Any unfinished work required by the
State consent orders was subsumed into the permit. In November 1999, the NYSDEC requested
EPA to take over as lead agency for the site. EPA is in the process of completing the investigation
and remediation of the site using the federal Superfund Program.
The removal and disposal of approximately 1,820 tons of mercury contaminated soil and 410 tons of
PCB contaminated soil during 1985 addressed any immediate risks associated with direct contact. In
addition, the PRP completed construction of a new furnace building, which had state-of-the-art air
pollution control equipment. Site investigatory and clean up work will be completed under the
federal Superfund Program.
