Dewey Loeffel Landfill Cleanup

EPA Discharge Update - December 16, 2014 4:48:34 PM

Direct discharge of treated water from the treatment plant at the Dewey Loeffel Landfill Superfund site began on December 2, 2014. The treatment plant was designed to treat the contaminated ground water and liquid that seeps out from the landfill, called leachate. While there are no tanks remaining on site to store the treated water before it is discharged, the treated water continues to be sampled. Sampling of the treated water is being conducted in accordance with the discharge requirements set by the New York State Department of Environmental Conservation, which are designed to be protective of the water body receiving the discharge. There are weekly, biweekly and quarterly sampling requirements. The data from the sampling conducted on December 4, 2014 show no detectable levels of most compounds tested for. The sampling data has been posted online and is available on the EPA's Dewey Loeffel site webpage<http://www.epa.gov/r02earth/superfund/npl/dewey/>.

The new treatment system (HiPOx) is also in the process of being added to the plant to further address the long-term treatment of the chemical 1,4-dioxane. The unit has arrived on site and is being installed. It is expected to be brought online by next week. The existing carbon filter unit in the plant will continue to treat 1,4-dioxane until the additional treatment system is brought online and will remain in place after the new system is installed. The plant is currently operating at a reduced flow rate of 0.5 gallons per minute (gpm). Once the new treatment system is in place the plant will resume operating at approximately 2 gpm. Additional information about the continued operation of the plant and further increases in flow rate operations can be found at the link below.

EPA Final Tank Discharge and Update - December 1, 2014

The EPA has completed its review of samples taken from the forty-eighth tank of treated water ("Tank 48") from 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. All compounds were well below the limits set by the New York State Department of Environmental Conservation (NYSDEC) for discharging into the Valatie Kill. Based on this data, the EPA is approving the discharge of Tank 48 for Monday, December 1, 2014.
Tank 48 is the final tank being discharged. All tanks discharged have met the discharge requirements as set by the NYSDEC.

Direct discharge to the Valatie Kill will begin December 2, 2014. The comprehensive sampling program has demonstrated that the treatment plant is working successfully. As announced last July, a new treatment system (HiPOx) is being added to the treatment plant to further address the long-term treatment of the chemical 1,4-dioxane. To date, the granulated activated carbon system in the plant has been effectively treating 1,4-dioxane. The carbon filter system will continue to treat 1,4-dioxane until the additional treatment system comes online and will remain in place after the new system is installed. To provide further assurance to the community, a carbon filter unit in the plant was replaced with fresh, new carbon on November 20. In addition, beginning on December 2, the water treatment plant will operate at a reduced flow rate of approximately 0.5 gallons per minute (gpm) until the new treatment unit for 1,4-dioxane is operating. It is estimated that the equivalent of less than one tank of treated water will be directly discharged during the 2-3 week delivery and installation period. Once the new treatment system is in place the plant will resume operating at approximately 2 gpm. Additional information about the continued operation of the plant and further increases in flow rate operations can be found at the link below.

Resident Update on Loeffel Toxic Waste Site Concerns – October 1, 2014

The EPA has contacted the Town regarding testing at the Loeffel site and has provided some background information about the inaccurate testing.

EPA provided the following information:

"The labs currently conducting these tests are Pace Analytical , St. Peter's Hospital Environmental Laboratory (BOD 5), and ALS Group (1,4-dioxane). Please note that none of the samples collected at the water treatment plant to date are the subject of the Department of Health (DOH) settlement with Pace Analytical. The DOH settlement referred to testing methodology employed between 2006 and August 29, 2013. The treatment plant began collecting discharge samples in January 2014. It is important to note also that the analysis of volatile organic compounds and 1,4-dioxane was not the subject of the settlement. Pace continues to be certified under the NYSDOH Environmental Laboratory Approval program."

They additionally stated in a community update:

"The EPA has completed its review of samples taken from the thirty-ninth tank of treated water ("Tank 39") from 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. All compounds 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 is approving the discharge of Tank 39 for Wednesday, October 1, 2014."

Resident Update on Loeffel Toxic Waste Site Concerns – September 26, 2014
 
Many residents have contacted my office regarding news reports of faulty tests conducted relative to contamination at and around the Dewey Loeffel Toxic Waste Site. Please note that these tests involve the New York State Department of Health (DOH) and supervision of the site is the responsibility of the United States EPA (EPA).
As of the date of this notice, neither the EPA nor the DOH has contacted the town of Nassau regarding the failures of oversight at the toxic landfill.  They have not provided the community with the context of this matter of contamination nor any information on how it may have impacted remedial action decisions to date.
We did not learn of this situation until we read about it in the newspaper.
We have contacted both agencies and you may read our letter here.  If we receive any information, we will be sure to share this information with you on this website.

EPA update on Dewey Loeffel discharge of treated water - June 24, 2014

 

The EPA has completed its review of samples taken from the twenty-fourth tank of treated water ("Tank 24") 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. The compound 1,4-dioxane was detected at a very low level. All compounds were 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 is approving the discharge of Tank 24 today.


On Monday, June 23, the treatment plant began a short-term ramp up to demonstrate how the plant operates at increased flow rates, up to 4.2 gallons per minute. To date, the EPA has taken a conservative approach with the slow startup of the plant to ensure that it is working properly. In the future, during normal operations, the plant will need to operate at an increased flow rate to efficiently treat the amount of leachate and ground water coming into the plant. The treatment plant was designed to effectively treat ground water and leachate at rates up to 15 gallons per minute. This demonstration will provide additional information about plant operations at increased flow rates.

Over the course of the next four weeks, five storage tanks will be filled with treated water. Of those five tanks, three tanks will be filled with treated water from the plant at an increased flow rate of up to 4.2 gallons per minute. The EPA will continue to review sampling data carefully before allowing the contents of each successive tank to be discharged. Due to the increased flow rate, some modifications to the existing sampling schedule will be required. Sampling will, at a minimum, be consistent with the requirements set by the New York State Department of Environmental Conservation. Each tank will continue to be tested for volatile organic compounds and (VOCs) and 1,4-dioxane. Once this sequence of five tanks has been filled, the plant will go back to operating at the lower flow rate of approximately 2 gallons per minute.

The EPA has completed its review of samples taken from the eighteenth tank of treated water ("Tank 18") from the newly constructed treatment plant at the Dewey Loeffel Landfill Superfund site located in the town of Nassau. Consistent with previous data, the results for Tank 18 showed no detectable levels of most compounds tested for. However, the result for 1,4-dioxane was higher than previous samples. The Tank 18 samples are being re-analyzed and the EPA is evaluating what factors may be contributing to this result. Tank 18 will not be discharged to the Valatie Kill until this assessment is completed. The EPA expects that the contents of Tank 18 will be re-run through the treatment system.

The EPA has taken a conservative approach with the slow startup of the treatment plant to ensure that it is working properly. As part of this process, the EPA is requiring that water treated in the plant be pumped into tanks and thoroughly tested before discharge to the Valatie Kill is allowed. For the majority of compounds, the plant has been operating as expected. This conservative approach is also providing the EPA with valuable information about the impacts of 1,4-dioxane on the plant as a whole and, more specifically, to the carbon treatment units which are responsible for its removal. The EPA is also continuing to explore additional long-term treatment options for 1,4-dioxane.

EPA Loeffel Update - May 1, 2014

The EPA has completed its review of samples taken from the sixteenth tank of treated water ("Tank 16") 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 16 to be discharged into the Valatie Kill on Thursday, May 1, 2014.

Update 13 March 2014

 

The EPA has completed its review of samples taken from the ninth 20,000 gallon tank of treated water ("Tank 9") 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. The compound 1,4-dioxane was detected at a low level. 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 9 to be discharged into the Valatie Kill on Thursday, March 13, 2014.

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.
