USEPA Update on Testing of Potential Mead Road Crossing
August 6, 2013
Attached are the preliminary results for the samples collected on 6/24 from the discharge pipeline. Also attached are the preliminary packages and figures that show the boring locations and summarize the data. Some observations:
* With one exception, all PCB results were much less than 1 ppm less than 0.1 or non detect). The one exception was 1.19 ppm at B10 (2-5'). B10 is located north of Mead Road, south of the culvert under the T11A access road.
* B12A or B13A samples were not analyzed (and were collected in case elevated hits were found at the nearest boring). PCBs were ND at 13 and B14, and were much less than 1 ppm at B12.
* There were no SVOCs detected.
* The only pesticide detected was Hexachlorobenzene at 0.0216 ppm at B10 (2-5').
* There were a few detections of VOCs, namely acetone, 2-butanone aka MEK), TCE and 1,2-dibromo-3-chloropropane. Acetone and MEK are both EPA-recognized laboratory contaminants. Further, even the highest detections of acetone and MEK are pretty low, 0.0385 ppm at B12 (2-5') and 0.00794 ppm at B10 (2-5'), respectively. The detections of TCE were lso quite low, the highest being 0.00314 ppm at B11 (2-5'). The single detection of 1,2-dibromo-3-chloropropane was 0.00114 ppm at B11 (0-2'), the dup of that sample was non-detect.
* Hg results were non detect As for the other metals, there are, as expected, detections, but they are appear to be low and could represent background.
The U.S. Environmental Protection Agency will hold a public information meeting to update residents and other interested parties about activities at the Dewey Loeffel Landfill Superfund Site on Thursday, May 16, 2013.

February 15, 2013 Update from EPA
Following a recent meeting with the USEPA, the following materials were provided.
Attached you'll find: the final effluent limits for the treatment plant; a few maps with the
of the plant identified (these will be superseded by recent design
documents); a map with monitoring wells and a map with residential wells
that are sampled and their frequency. There were some questions
regarding the ground water sampling and thought the maps would be
useful. All these documents are available below in the Documents section of this page.
Toxic Site Update
EPA has indicated that they will be following up with a
more detailed monthly update shortly, but wanted to give the Town a quick heads
up about some additional activities/testing (Phase III Treatability Tests) that
will be conducted at the Site. These activities are minor in nature. The
tests will be contained/conducted in the pole barn. There will no activities related to the Phase III
Treatability Test that will occur outside the pole barn other than unloading
equipment/supplies. The equipment (basically two 55 gallon
drums, piping, pumps, treatment material, and secondary containment) for the
testing will be set up on Wednesday/Thursday of this week. There will be a
few site visits outside the normal Mon-Thurs trucking schedule while this goes
As part of the design of the treatment plant, the
potentially responsible parties have been conducting treatability studies (to
test the various treatment processes and their ability to remove the
contaminants form the water/leachate). Most of these tests were done
off-site (water and leachate was shipped to the testing facility). They
will be doing some additional testing on-site so that they can use the
water/leachate directly pumped from the tank (something more in keeping with
the actual system when up and running). Again this will be conducted in
the pole barn and any treated water and leachate not collected for analysis
will be discharged back into the frac tanks and disposed as usual.
The actual testing should begin on Friday, January 11 and last thru January
21. Samples will be collected during this time frame. The equipment
will likely be kept in place for a few additional days beyond January 21 as
they evaluate test results and then disassembled if no further testing is

Dear Supervisor Fleming:
As a follow-up to my
previous email on October 17, 2012, I am providing the following additional
information concerning your October 11, 2012 email regarding the trucking
operations at the Dewey Loeffel Landfill Superfund site. I apologize for the
delay in getting you this information, but yesterday was the first day that I
was back in the office since Hurricane Sandy.
As a result of
discussions between EPA and the responsible parties, the trucking subcontractor,
Clean Harbors, has discussed the concerns raised in your 10/11/12 email with
each of the vac truck drivers, has reviewed the transportation operating
procedures (SOPs) for the site and has added language prohibiting convoying of
vac trucks. Previously, loads were being scheduled at 30 minute intervals in an
effort to avoid trucks departing the site at the same time. In addition, any
new drivers will have the transportation SOPs reviewed with them prior to being
scheduled for pickups at the site.
ARCADIS, the responsible parties'
contractor overseeing the truck loading operations at the landfill will also
continue to reinforce with each of the drivers at the site the procedures that
have been in place since operations commenced. These include; (a) the truck
route, (b) adhering to scheduled arrival times, (c) adhering to blackout times
(based on the school bus schedule), and (d) avoiding the arrival and departure
of more than one truck at a time.
The following is additional
informational that was developed by Clean Harbors and is provided to its
truckers regarding the transportation SOPs for the site. Please let me know if
you would like to discuss this matter further. thank you

and maintenance (O&M) of the groundwater extraction and leachate collection
systems. Trucking operations are scheduled for each Monday and Thursday of the
week, except as adjusted for holidays.
2. On September 24, 2012
Supervisor Fleming informed EPA that the Nassau area held a Mass Casualty
Incident Drill during the weekend involving 19 agencies. During that program he
was advised that the trucking operation at the Dewey Loeffel site has involved
truck convoying once the tankers leave the site. EPA has been following up on
this matter and has been told by GE and SI there have been instances where two
trucks have left the site together after loading. Although this practice is not
common, it has happened. However, EPA is not aware of any regulations that
prohibit this activity. If this is not correct, please let me know of any
regulations that you believe would prohibit this activity.
completed improvements to the Mead Road trucking route between September 4 and
8, 2012 in accordance with the recommendations provided during EPA's summer 2012
safety evaluation. This included the installation of geotextile fabric and stone
lined drainage swales on both sides of the road for a stretch of over 600 feet
where the roadway was most susceptible to destabilization and erosion caused by
storm water flow (the "choke point"). The drainage swales are designed to reduce
the flow of water over the road surface, making it more stable and less likely
to erode and become narrower during heavy rain storms. An engineer was present
on-site during the construction to ensure that the work met the engineering
specifications. The property owner was also present during the construction and
approved of the work.
4. EPA also cleaned out and armored several
culverts along Mead Road to enable them to more effectively carry storm water
off the road surface. A stone ditch was added after the outfall of one of the
culverts to reduce the potential for a heavy storm surge to erode the road
shoulder nearest to the culvert.
5. Additional signage was installed
along the road on September 12 and 13, 2012. Hazards signs were placed in areas
where they can help to delineate the road shoulders when they are covered with
snow or leaves.
Design of Groundwater Treatment Facility:
September 5, 2012, EPA conditionally approved the Preliminary Design Plan for
this facility. GE and SI have since commenced the field work identified in the
Plan. The field work includes collecting data to support the design and
construction of the facility. The results of this field work will be documented
in a Preliminary Design Data Report, which is currently scheduled to be
submitted to EPA for review by December 4, 2012.

EPA Reaches Agreement with General Electric Company and SI Group, Inc. to Protect Drinking Water at the Dewey Loeffel Landfill Superfund Site in Nassau, New York
Contact: Larisa Romanowski, (518) 747-4389, firstname.lastname@example.org
(New York, N.Y. - April 11, 2012) The U.S. Environmental Protection Agency today announced that it has entered into an agreement with the General Electric Company and SI Group, Inc. (formerly Schenectady Chemical) to collect and properly dispose of contaminated ground water and liquid leaching from the Dewey Loeffel landfill that is threatening several nearby drinking water wells. The liquid seeping from the landfill, called leachate, and the ground water are contaminated with volatile organic compounds, which can cause cancer in people. The extent and nature of potential health effects depend on many factors, including the level and how long people are exposed to the contaminants.
The EPA is currently collecting the contaminated liquid waste and sending it off-site for disposal. Under the agreement, General Electric and SI will take on the collection and removal of the waste and the construction of a treatment plant adjacent to the landfill, all with EPA oversight. The waste will continue to be sent off-site until the construction of the treatment plant is completed. Treated water from the new system will be discharged to surface water only after the EPA verifies that sampling data shows that the treatment system is working effectively and is capable of meeting stringent state discharge limits. GE and SI Group have agreed to reimburse EPA for certain costs, including an upfront payment of $800,000.
"The EPA has determined that treating the contaminated ground water and liquid at the site is an effective way to protect people's drinking water wells while the EPA investigation of the site continues," said Judith A. Enck, EPA Regional Administrator. "The treatment system that will be constructed near the landfill will alleviate the impacts of the hundreds of truck trips needed to dispose of the waste off-site."
The treatment system to be constructed will address potential threats from the contaminated ground water and leachate and community concerns about trucking the contaminated liquid off-site. A comprehensive long-term study is underway, which will identify permanent cleanup options, called remedial actions, for the contaminated ground water, surface water and sediment associated with the site. The permanent cleanup plan may include changes to the leachate collection, ground water extraction and treatment systems.
The Dewey Loeffel Landfill site is located in southern Rensselaer County, approximately four miles northeast of the village of Nassau. From 1952 until 1968, the site was used for the disposal of an estimated 46,000 tons of waste materials generated by several Capital District companies. The waste included industrial solvents, waste oils, polychlorinated biphenyls, scrap materials, sludge and solids. Volatile organic compounds and other hazardous substances have seeped out of the landfill and contaminated the ground water. PCBs have also moved downstream, causing contamination of sediment and several species of fish in and near Nassau Lake.
From 1980 until the site was added to the federal Superfund list in May 2011, numerous investigations and cleanup actions were performed at the site under the New York State Department of Environmental Conservation's Superfund program. In the fall 2011, the EPA took responsibility for operating ground water and leachate collection systems that had been installed by the state.
The EPA has a web page about the site at: http://www.epa.gov/region2/superfund/npl/dewey <http://www.epa.gov/region2/superfund/npl/dewey > <http://www.epa.gov/region2/superfund/npl/dewey>

EPA REGION 2, DEWEY LOEFFEL LANDFILL SUPERFUND SITE PROJECT UPDATE, December, 2011
DEWEY LOEFFEL LANDFILL SUPERFUND SITE INVESTIGATION CONTINUES
The U.S. Environmental Protection Agency (EPA) investigation of the landfill and groundwater contamination components of the Dewey Loeffel Landfill Superfund Site began last spring.
In April, field crews completed magnetic and electromagnetic geophysical surveys of the landfill to assess the presence of residual sources of buried contamination in the landfill. Additional tests were conducted to evaluate the current integrity of the existing landfill cap by assessing the physical and geotechnical properties of the cap.
The Landfill Cap Investigation was initiated in May 2011. A total of 20 borings were advanced through the landfill to evaluate the thickness of the cap. Twenty subsurface landfill cap samples and 10 surface soil samples were collected, and submitted for geotechnical analyses. The technical report with the results of the landfill investigation is available on EPA Region 2’s Dewey Loeffel web page at http://www.epa.gov/region2/superfund/npl/dewey/.
In May, EPA also identified the locations of five groundwater monitoring wells to further evaluate groundwater and contaminants. Well installation began in late June and was completed in mid-July. Groundwater samples and geophysical information was collected through September. A report summarizing the results of the groundwater investigations is expected this winter. Additional groundwater investigations may be necessary and are dependent on the findings of the report.
Additional details, as well as future activities, have been documented in a work plan, which is available on the Dewey Loeffel page of the EPA website at http://www.epa.gov/region2/superfund/npl/dewey/.
EPA TAKES OVER NYSDEC EXTRACTION WELL OPERATIONS
Since 2008, the New York State Department of Environmental Conservation (DEC) had been operating three groundwater extraction wells to reduce contaminant concentrations and prevent the spread of the groundwater plume. In October 2011, EPA’s Removal Program took over responsibility for the operation (pumping) and maintenance of the leachate collection system and groundwater extraction wells. EPA’s action also included winterization of the extraction well system to allow for year-round operation of the wells, as well as disposal of the collected leachate and groundwater.
As part of the winterization of the extraction well system, an additional above ground storage tank was installed, insulated structures were built on-site to enclose the aboveground piping for the extraction wells and a heated barn was constructed around the aboveground storage tanks. More detailed information regarding the winterization of the extraction well system and EPA's removal action can be found in the Pollution Report (POLREPS) section of the following website: www.epaosc.org/DeweyLoeffelLandfill.
TECHNICAL ASSISTANCE GRANT (TAG) AWARDED
A Technical Assistance Grant (TAG) has been awarded to “United Neighbors Concerned About GE Dewey Loeffel Landfill (UNCAGED)” for the Dewey Loeffel Landfill Superfund Site. TAG funding allows qualified community groups to contract with independent technical advisors who can interpret and help the community understand technical information about their local Superfund site. More information about TAG’s is available at http://www.epa.gov/superfund/community/tag/.
Interviews with local officials, organizations, and community residents began over the summer for the Community Involvement Plan (CIP) for the Dewey Loeffel Landfill Superfund Site. The CIP will identify the ways that EPA will involve the community and the tools and activities that will be used to share information and receive public feedback as the project progresses. The draft CIP is expected this winter and will be made available for public input. If you have questions about EPA’s community involvement program, contact Larisa Romanowski at (518) 747-4389, or by email, firstname.lastname@example.org.
The Nassau Free Library has been established as the Information Repository for the Dewey Loeffel Landfill Superfund Site. Project documents will be available at the library by request, and will also be available online at http://www.epa.gov/region2/superfund/npl/dewey/.

Loeffel Site Update – November 21, 2011
The Town of Nassau has been reminded that the USEPA is not required to obtain permits for ongoing removal action. However, they have advised us that they would be willing to discuss and address any concerns the municipality has moving forward. They have provided the Town with the section of CERCLA regarding permitting, as well as the engineer's drawings (signed by a NY State Registered P.E.) for the pole barn that's currently being constructed around the frack tanks for winterization and waste removal. The pole barn will be insulated and heated with propane heaters which will be powered by a generator until power lines can be brought to the Site. All building and installation is being conducted by licensed and certified professionals within proper code.
More detailed information regarding the winterization of the extraction well system and EPA's removal action can be found in the "POLREPS" section of www.epaosc.org/DeweyLoeffelLandfill. USEPA has also submitted the Administrative Record for this removal action for public review at the Nassau Free Library. The Administrative Record provides documentation for the basis of our decision to conduct this removal action.
October 2011 EPA UPDATE ON THE LOEFFEL TOXIC WASTE SITE
EPA will be assuming responsibility for the operation (pumping) and maintenance of the leachate collection system and groundwater extraction well system at the Site, which are currently being operated by NYSDEC. Contracting mechanisms are being set up for weekly transportation of the collected leachate and groundwater to off-Site treatment and disposal facilities. In addition, EPA will be winterizing the extraction well system and associated storage tank to allow for year-round operation of the system.
This work is being conducted as an action initiated by EPA’s Removal Program. From October 17-20, 2011, insulated enclosures were constructed around the aboveground portions of the piping for the extraction well system. On October 19, 2011, an additional storage tank for the extraction well system was also installed to increase the storage capacity of the groundwater collection/extraction well system. In addition, on October 25, 2011, construction of a heated barn which will enclose the aboveground storage tanks is scheduled to begin.

LOEFFEL UPDATE- July 2011:
The following information picks up where we left off with the last Loeffel Site update.
The well drillers completed their mobilization to the Loeffel Site on Tuesday, June 21. Drilling operations began on June 23 and are reported to be progressing well. EPA has reported that it is anticipated that the drilling and development of the monitoring wells will be completed this week. Nassau’s Mr. McCagg reports that the EPA subcontractors are on well number four of five and expect to be done by Wednesday.
The Town has supplied support as far as property and water storage usage. After demobilizing the contractors are expected to return in approximately three weeks to test the wells they just installed. Following that work, it is anticipated that geophysical evaluation and further testing of the wells (including sampling) will be scheduled for August.
Additionally, EPA reports that the extraction well system has been started up by the NYSDEC and should be fully operational by the week of July 18th.
