Dewey Loeffel Landfill Cleanup

EPA Loeffel Update - April 2, 2014


The EPA has completed its review of samples taken from the twelfth tank of treated water ("Tank 12") from the newly constructed treatment plant at the Dewey Loeffel Landfill Superfund site located in the town of Nassau. The treatment plant was designed to treat the contaminated ground water and liquid that seeps out from the landfill, called leachate. The data show no detectable levels of most compounds tested for, including PCBs and 1,4-dioxane. All other compounds (some metals and mercury) were well below the limits set by the New York State Department of Environmental Conservation for discharging into the Valatie Kill. Based on this data, the EPA will allow the treated water from Tank 12 to be discharged into the Valatie Kill on Thursday, April 3, 2014.

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.

Loeffel Toxic Site Update

January 9, 2013

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 on. 

 

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 required.

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

September 2012 Loeffel Update from USEPA
The following is a brief summary of some of the work that has been completed at the Dewey Loeffel Landfill Superfund site during this past month and a schedule for upcoming activities currently planned for October. Please let me know if you have any questions about this information.

Pump and Truck Operations:

1. General Electric (GE) and the SI Group (SI) continued pump & truck operations as well as operation 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.

3. EPA 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:

1. On 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.


Community Update:

1. EPA anticipates that a community update will be developed for distribution to the public within the next 4 to 6 weeks.

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, romanowski.larisa@epa.gov

(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/.

COMMUNITY INVOLVEMENT  

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, romanowski.larisa@epa.gov.

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.

NYSDEC UPDATE on Groundwater Extraction

The following is the Loeffel 2011 Leachate and Off-site Groundwater Extraction report provided by NYSDEC and completed by the DEC consultant up to the point to when EPA took responsibility to operate the pump and truck systems.  This report is dated December 27, 2011.

EPA UPDATE – 8/31/2011

EPA recently provided an update on progress at the Dewey Loeffel site. As discussed in their last report, installation of the groundwater monitoring wells began in late June and was completed in mid-July. In August, geophysical evaluation began and further testing of the wells (including sampling) is underway. The groundwater evaluation is schedule to be completed by the end of September.

As you may recall, the Landfill Cap Investigation was initiated in May. The technical report with the results of the investigation is expected by the end of September and will be available on EPA’s website at http://www.epa.gov/region2/superfund/npl/dewey/.

A report summarizing the results of the groundwater investigations is expected at the end of this year. Additional groundwater investigations may be necessary and are dependent on the findings of the investigation.

 

 

The attachment represents a map with the well locations and properties identified for current EPA work on the Loeffel Site.  

EPA has placed 2 wells on property (A. Smith - Block 5 , Lot 20) .  Those are wells 3 and 5 on the attached map.   They have placed 3 wells on property (Block 5 , Lot 21).   Those are wells 1, 2, and 4. 

August 1, 2011 Update on the Loeffel Landfill

Attached is the May, 2011 Groundwater Sampling Event Monitoring Report completed by GE's consultant Tetra Tech Geo (formerly GeoTrans).  The report is dated July 28, 2011.  GE's consultant will conduct their fall groundwater monitoring well sampling in October.  As evidenced by sample results from OMW-222 and OMW-223 (all parameters were non-detect), the groundwater plume has not migrated further in that direction.  This sampling event is a separate effort from the residential well sampling which is conducted by GE's other consultant Arcadis.

 

Also, I would like to report that at the request of EPA, the DEC is now operating the off-site groundwater extraction wells.  You can expect that the number of tanker trips will increase considerably. EPA has completed the installation of five additional off-site monitoring wells and will be performing testing on them shortly.

LOEFFEL SITE CLEANUP UPDATE: June 17, 2011

Dear Community Members:

Please find information the Town has requested concerning the tanker trips and loads from the Loeffel Landfill by clicking the above link.  DEC reports that there were 14 tanker trips in the months of April and May.  Their claim is that the leachate composition has not changed.  Additionally, I want to advise you that EPA will begin the off-site monitoring well installation next week.  Their contractors are expected to begin efforts on June 20th.  The actual work is not scheduled to begin until the next day.   GE is also sending consultants out to conduct additional soil and sediment sampling in/near T11A beginning June 22nd.  This sampling is expected to take a few days.


Please let me know if you have any questions. 

Thank you and best regards.
