EPA Update to Nassau on Loeffel Work - November 21, 2017


Supervisor Fleming and Superintendent McCagg,

 

Below is a summary of the upcoming field work that is anticipated to occur outside of the landfill property itself, as well as some other notable upcoming or recently completed site activities.

  • Landfill/Groundwater Investigation:
    • As part of the investigation of shallow groundwater, the installation of 38 shallow wells at 19 locations both inside and outside of the landfill was completed in May 2017. Consistent with the approved investigation work plan, the locations and depths of these new wells were selected based upon the results of the direct-sensing investigation and the discrete groundwater and soil sampling conducted in 2016. Hydraulic conductivity testing, which measures how readily groundwater flows in the surrounding aquifer, was performed in the new shallow wells in summer 2017. The first groundwater sampling event for the new wells was completed in October 2017. Samples of non-aqueous phase liquid (NAPL) were collected from certain wells in mid-November 2017. The near-continuous water level monitoring program began in November 2017 and is scheduled to continue into spring 2018.
    • As part of the investigation of deep bedrock groundwater, three new deep bedrock boreholes were installed between December 2016 and February 2017. Several different sampling and testing activities were completed in the three bedrock boreholes between March 2017 and August 2017 (see previous updates for details). The conversion of the three boreholes into multi-level monitoring wells is scheduled to be completed in November 2017, followed by the sampling of the wells to help determine the nature and extent of deep groundwater impacts.
    • As part of the investigations of both shallow and deep groundwater, monthly water level measurements were collected in May-October 2017 for the new and existing monitoring wells, as well as for three surface water staff gauges located in Valley Stream. Water level measurements are scheduled to be collected at these locations again in late November and mid to late December 2017.
  • Drainageways Investigation:
    • No field work is expected in the next month.
  • Removal Action for Tributary T11A:
    • In accordance with the approved sampling and analysis plan, soil and sediment samples were collected from approximately 175 locations in the tributary in November 2017. A follow-up sampling event, if necessary, will be performed following the receipt and review of the results of the samples collected in November 2017. The majority of the habitat assessment and surveying field work has been completed, with some additional field work scheduled to occur later in fall 2017.
  • Monitoring and Other Activities:
    • In November 2017, samples were collected from all of the residential wells in the residential well monitoring program. The next residential well monitoring event is scheduled for February 2018 and will include residential wells monitored on a quarterly basis.
    • The next semi-annual groundwater sampling event is scheduled for spring 2018.
    • Water level measurements are collected from certain groundwater wells on a quarterly basis. The next quarterly event is scheduled for January 2018.
    • Surface water from the site drainageways is sampled annually on three occasions during the summer and fall. Two of the three 2017 sampling events have been completed with the third event scheduled for later in fall 2017.
  • Some of the abovementioned activities may be visible along roadways, such as Mead Road, Central Nassau Road and Curtis Hill Road.

October 4, 2017 Communication regarding review of Drainageways from EPA
EPA Project Update: 
Sent: Wednesday, October 4, 2017 2:41:56 PM
Subject: RE: Dewey Loeffel

Supervisor Fleming,

 

The EPA is nearing the conclusion of its final review of the Drainageways Site Characterization Summary Report, which provides a summary of historical data (including the data collected during phase 1 of the remedial investigation in 2015) and identifies additional data still needed and to be obtained during phase 2. As we complete our final review and await the finalized version of the report from General Electric (GE), I wanted to let you know how the Town of Nassau’s comments were ultimately addressed.

 

Town Comment #1: We recommend that further delineation of soil and sediment contamination be performed expeditiously so that remediation can occur to limit continuing spread of PCBs and other site related contaminants and to reduce exposure to residents living in the area.

 

As indicated in my September 19, 2017 email to you, the EPA and GE reached an agreement in early September 2017 for GE to conduct a removal action to address PCB-contaminated soil and sediment in Tributary T11A, which serves a source of contamination to downstream areas such as the Valatie Kill and Nassau Lake. The removal action will be performed by GE under EPA oversight and will consist of the excavation and disposal of PCB-contaminated soil and sediment, followed by the placement of backfill and restoration of habitat in the tributary. Additional sampling is scheduled for fall 2017 to further characterize the PCB-impacted sediment and soil, with the construction work scheduled for the summer and fall of 2018. The ongoing remedial investigation/feasibility study (RI/FS) of the surface drainageways will continue in parallel with the removal action work.

 

Town Comment #2: Analytical results include a number of other contaminants, such as heavy metals, pesticides, semi-volatile organic compounds and dioxins/furans. It would be helpful if the tables included a column that indicates levels of concern/action levels for comparison.

 

As a reference, a table containing the EPA’s regional screening levels has been added to the report as Appendix A3. These screening levels were developed using risk assessment guidance from the EPA’s Superfund program. The screening levels are risk-based concentrations derived from standardized equations combining exposure information assumptions with EPA toxicity data. The screening levels are considered by the EPA to be protective for humans (including sensitive groups) over a lifetime; however, they are not always applicable to a particular site and do not address non-human health endpoints, such as ecological impacts. The screening levels provided as Appendix A3 are generic and are calculated without site-specific information. Later in the RI/FS, both human health and ecological risk assessments will be performed to evaluate the risk of exposure to contaminants using site-specific data.

 

Town Comment #3: There are many sample results that indicate “ND” but with a concentration given in parentheses. The explanation is that the associated value is the compound quantitation limit. In some cases, the quantitation limit seems quite high, is that due to interferences in the soil/sediment sample or is there some other explanation? For instance, the analytical result for sample number NL15-IL-SED-01 (0-6 inches) for 2,4-dinitrophenol was ND (4,100) microgram/kilogram.

 

The contaminants are analyzed as separate parameters with different Chemical Abstracts Service (CAS) numbers and, as such, often have differing reporting limits. With respect to your concern that the quantitation limits seem high for some parameters (such as 4,100 micrograms per kilogram for 2,4-dinitrophenol), please be aware that this may be the result of different units of measurement.  For example, the quantitation limit of 4,100 micrograms per kilogram for 2,4-dinitrophenol is equivalent to 4.1 milligrams per kilogram (or parts per million). It is also important to keep in mind that different chemicals have varying levels of toxicity to humans. Using 2,4-dinitrophenol as an example again, the noncancer screening level associated with exposure to 2,4-dinitrophenol in residential soil is 130 milligrams per kilogram (or parts per million), which is significantly higher than the quantitation limit of 4.1 milligrams per kilogram (or parts per million). The EPA also confirmed with GE that no interferences between parameters occurred for the samples analyzed as part of the phase 1 investigation. It is noted that the phase 1 work was performed in accordance with an EPA-approved quality assurance project plan, which outlines the sampling, parameters, methods of analysis and quality assurance/quality control requirements for the work.

 

Should you have any questions, please let me know and we can set up a time to discuss further. The final version of the report, once available, will be posted on EPA’s Dewey Loeffel Landfill site webpage under “Additional Reports and Documents.”

 


August 15, 2017 EPA Upcoming Loeffel Field Work Update
Supervisor Fleming and Superintendent McCagg,

 

Below is a summary of the upcoming field work that is anticipated to occur outside of the landfill property itself, as well as some other notable upcoming or recently completed site activities.

·         Landfill/Groundwater Investigation:

o   As part of the investigation of shallow groundwater, the installation of 38 shallow wells at 19 locations both inside and outside of the landfill was completed in May 2017. Consistent with the approved investigation work plan, the locations and depths of these new wells were selected based upon the results of the direct-sensing investigation and the discrete groundwater and soil sampling conducted in 2016. Hydraulic conductivity testing, which measures how readily groundwater flows in the surrounding aquifer, began in the new shallow wells on July 31, 2017 and is expected to continue through August 2017. These new wells are scheduled to be sampled in fall 2017 to help determine the nature and extent of shallow groundwater impacts.

o   As part of the investigation of deep bedrock groundwater, three new deep bedrock boreholes were installed between December 2016 and February 2017. Several different sampling and testing activities are scheduled to be conducted within the three bedrock boreholes before they are ultimately converted into multi-level monitoring wells and sampled in fall 2017 to help determine the nature and extent of deep groundwater impacts. The first of these additional sampling/testing activities was a geophysical survey, which was completed in March 2017 to locate water-bearing zones within the bedrock matrix. Based on the results of the geophysical surveys, targeted groundwater sampling (referred to as packer testing) was completed in early June 2017. Transmissivity profiling was performed in these wells in July 2017 to identify significant groundwater flow paths.

o   As part of the investigations of both shallow and deep groundwater, monthly water level measurements were collected in May 2017, June 2017 and July 2017 for the new and existing monitoring wells, as well as for three surface water staff gauges located in Valley Stream. Water level measurements are scheduled to be collected at these locations again during the week of August 21, 2017 and in mid to late September 2017

o   As part of the investigation of vapor intrusion, the installation of three shallow groundwater monitoring wells was completed in August 2016. One well was installed at a property along Central Nassau Road and two wells were installed at a property along Mead Road. An initial sampling event for the three wells was completed in March 2017, and the results indicated that all volatile organic compounds were not detected. Consistent with the approved investigation work plan, a second sampling event for the three wells was completed on July 6, 2017 and the results are forthcoming. The results of these sampling events will be used to evaluate the potential for vapor intrusion.

o   Some of the abovementioned activities may be visible along Mead Road, Central Nassau Road and Curtis Hill Road. Traffic control measures were implemented during the preceding month and may be required during the upcoming month.

·          Drainageways Investigation:

o   No field work is expected in the next month.

·         Monitoring and Other Activities:

o   The next residential well monitoring event is scheduled for November 2017 and will include all of the residential wells included in the program.

o   Quarterly water level measurements are scheduled to be collected next during the week of August 21, 2017.

o   Five existing bedrock boreholes were converted into multi-level monitoring wells in July 2017 and will be included in the next semi-annual groundwater sampling event scheduled for late September/early October 2017. The 2016 Groundwater Monitoring Report is available on the EPA’s Dewey Loeffel site webpage under “Additional Reports and Documents.”

o   The annual surface water monitoring program, which includes the collection and analysis of surface water samples from the site drainageways in three separate events, is scheduled to be conducted during the summer and fall of 2017. The 2016 Surface Water Sampling Report is available on the EPA’s Dewey Loeffel site webpage under “Additional Reports and Documents.”

o   The annual fish monitoring program includes the collection and analysis of fish tissue samples from the site drainageways. Samples were collected from three locations in the Valatie Kill near Krouner Road on June 22-23, 2017 and samples were collected from the remaining locations on July 27-28, 2017. The 2016 Fish Sampling Report is available on the EPA’s Dewey Loeffel site webpage under “Additional Reports and Documents.”

Supervisor Fleming,

 

We have utilized numerous resources in our evaluations, which have included: the State of New York’s designation of the Valatie Kill as a Classification C for waters supporting fisheries and suitable for non-contact activities; USEPA guidance (including risk assessment guidance, policies and guidelines including Superfund-specific guidance); engineering principles such as mass balance chemistry; site sampling data; and other site- and chemical-specific factors. I recognize that this response may be better understood with further explanation and so I would be happy to set up a meeting with our project team to further discuss this information, if you are interested. Also, as I mentioned in my previous email, if you have specific information that supports that the levels of discharge are unacceptable, we would be pleased to consider that information.

Supervisor Fleming;

Joe Battipaglia shared your June 7th email with me concerning the discharges of treated water from the treatment plant at the Dewey Loeffel Landfill site.  I do not agree with the statement in your email that EPA’s April 17, 2017 letter is “political and not based on science or EPA conduct in other state jurisdictions”, as well as your reference to “New York’s failure to protect my community”, which I take to mean EPA’s failure to protect your community.  The actions that EPA has required at the site have been based upon site-specific factors and sound science, and have not been inconsistent with actions taken elsewhere.

 

You have repeatedly indicated that the discharge results are unacceptable based on comparisons to drinking water standards. As we have explained, comparison to drinking water standards is inappropriate because the Valatie Kill is not utilized as a drinking water source. If you have specific information that supports that the levels of discharge are unacceptable, we would be pleased to consider that information.  In the meantime, EPA staff will continue to diligently oversee operations at the plant to ensure that the plant is working as efficiently and effectively as possible.

Supervisor Fleming,

 

With respect to the treatment system at the Dewey Loeffel Landfill Superfund site, as indicated in Larisa’s June 1, 2017 email, a carbon filter change-out was performed on May 25, 2017 in an effort to increase the system’s removal of 1,4-dioxane. The data reflecting the carbon filter change-out are expected to be available next week.  As indicated by letter of April 17, 2017, the EPA and the responsible parties continue to evaluate additional adjustments to the system to increase the effectiveness and efficiency of contaminant removal.  

 

Thank you,
Joe
