Chemung County Landfill
On August 4, 2011, NYSDEC Commissioner Joseph Martens issued a decision on a petition brought by Residents for the Protection of Lowman and Chemung challenging the legality of disposing Marcellus Shale drill cuttings in a New York landfill owing to high levels of naturally occurring radioactivity in the cuttings. The Commissioner dismissed the petition on procedural grounds, but only after directing NYSDEC Staff to conduct a dozen or so investigations into safety measures. The decision affirms an administrative law judge ruling, concluding that a petition directly to the Commissioner challenging the legality of landfilling Marcellus Shale drill cuttings is the proper vehicle, rather than a petition challenging a permit modification to increase disposal volume. A summary of the decision can be found here. The decision in full is available here. No direct petition to the Commissioner has been filed. Citizens had an opportunity to comment on these issues again in 2013, because the Hyland Landfill in Angelica requested a waste rate increase, and Hyland takes large volumes of Marcellus Shale drill cuttings plus solidified Marcellus Shale wastewater, sludges, filtration residues and spill-contaminated soils from Marcellus Shale drill sites in Pennsylvania.
Until 2005 the Chemung County Landfill was a county landfill. The County generates 60,000 to 80,000 tons of solid waste for disposal per year. All of that went to the landfill, very little came to the landfill from anywhere else. In 2005 the County leased its integrated waste management operations --the landfill, a recycling facility, transfer stations and several other facilities-- to a subsidiary of Casella Waste Systems of Vermont, New England Waste Systems of New York (NEWSNY).
In late 2009 NEWSNY began disposing drill cuttings from Marcellus Shale drilling sites in Pennsylvania. The company did not notify DEC until December, and DEC approved the practice on January 21, 2010, by email. By March and April of 2010 over half the total waste receipts for the landfill were Marcellus shale drilling wastes, over 60,000 tons per year. Also in March and April of 2010 NEWSNY accepted about 180 tons of contaminated soil from Marcellus shale drilling sites in PA, contaminated by spills of fracking fluid. (About 30 percent of fracking fluid injected into Marcellus Shale wells returns to the surface as waste.) Both kinds of waste are can be about 25 times more radioactive than background at the surface.
Soon after DEC approved this practice NEWSNY applied for a modification of the landfill's permit to increase waste volume 50 percent, from 120,000 to 180,000 tons per year, and began diverting county waste to other landfills in order to devote the space to drill cuttings. Because drill cuttings displace only about one-forth of the landfill's permitted air space (the permit limits the height of the landfill), by charging the same per-ton fee for drill cuttings NEWSNY makes four time more money than it does by disposing other solid wastes.
During the proceeding initiated by RFPLC's challenge, NEWSNY disclosed that since 2009 it has been disposing Marcellus Shale drilling wastes in Angelica (Hyland Landfill) and Painted Post (Hakes C&D Landfill) as well as the Chemung County Landfill. It has since come to light that Marcellus Shale drill cuttings are also being disposed at Modern Landfill in Niagara County, NY.
This is occurring after comments in 2009 by New York State Department of Health, USEPA, and a number of environmental scientists and organizations called on DEC to study the risks and benefits of Marcellus shale gas development, including the question of how to manage low-level radioactive solid and liquid waste.
Marcellus shale drilling wastes
RFPLC argued, through its radioactive waste expert Dr. Marvin Resnikoff, that Marcellus Shale drill cuttings are unusually radioactive, owing to a high concentration of Radium-226, a decay product of Uranium-238 which is known to occur in high concentrations in shale formations that originate in briny conditions of ancient evaporative sea water; that Ra-226 (unlike U-238) is soluble in water; and that, as a result, brine and cuttings returned to the surface during well development concentrate Ra-226 by separating the radium from the uranium remaining in the formation. Ra-226 in the formation is about 25 times more radioactive than background radioactivity in the surface environment (which is already elevated everywhere owing to fallout from past nuclear bomb testing) and the water surrounding wet drill cuttings as they come up from a wellbore can be as high 1,000 times background. Dr. Resnikoff had been working for over ten years in the Barnett Shale gas fields in Texas, which is a similarly briny shale formation.
Radium is particularly hazardous because when ingested by either inhalation or by drinking contaminated water, it concentrates in the bones, and a substantial portion seeks out soft tissue in the body, particularly bone marrow. It is thus linked to bone cancer and leukemia, which is usually fatal. Ra-226 is also bioaccumulative, so absorption of the radionuclide by aquatic plants and microorganisms become increasing concentrated in the bones and issues of aquatic animals as smaller life forms are ingested and move up the food chain, resulting in the highest concentrations in fish. This has been the basis for EPA's primary drinking water standards for radium since 1975.
Casella was accepting dewatered but still wet (and often leaking) loads of cuttings hauled from Pennsylvania drill sites. This raised the issues of exposure from road dust contaminated by leaking trucks as well as the effect of relatively high concentrations of Ra-226 in the waste mass of the landfill, and the leachate generated by the landfill and hauled to the Elmira water treatment plant, ultimately discharged into the Chemung River.
RFPLC's attorney argued that New York's landfill regulations prohibit disposal of naturally occurring radioactive materials if they are also "processed" and "concentrated." DEC Staff argued that Marcellus Shale drill cuttings are more like gravel mine wastes and are neither processed nor concentrated. On this argument, it does not matter how radioactive the wastes are; they can be legally dumped in a New York landfill.
RFPLC also argued, through its engineering expert, Cornell University Professor Anthony Ingraffea, that unlike gravel mine wastes, drill cuttings are dewatered and otherwise processed in a variety of ways before being readied for hauling to a landfill. Dr. Ingraffea was one of the pioneers in researching hydraulic fracturing over two decades ago, when the mechanics of deep rock fracturing was first developed.
None of these arguments prevailed against DEC Staff's resistance. Casella submitted lab analysis of radioactivity of a limited sample of drill cuttings whose origin the company refused to disclosed, by a lab that is not certified to analyze radioactivity in waste as required under DEC regulations. The presiding administrative law judge nevertheless ultimately ruled that procedurally, it is improper to raise the issue of the nature and potential consequences of substantially altering the nature of the waste being disposed at the Chemung County Landfill in a proceeding designed to decide only whether the volume of waste the landfill accepts could be increased. On appeal, the DEC Commissioner Joseph Martens agreed and the petition was dismissed. However, based on RFPLC's concerns Commissioner Martens ordered DEC staff to undertake over a dozen additional investigations into how effective radiation monitoring at the landfill will be.
These investigations also turned out to be controversial. For example, DEC Staff allowed Casella to utilize gamma detectors at the landfill gate to determine whether haul loads of drill cuttings are excessively radioactive. However, as Dr. Resnikoff testified, Ra-226 is an alpha-radiation emitter, and alpha rays cannot pass through the skin, let alone the steel walls of a haul truck. (Health concerns are focused on pathways for ingestion of Ra-226.) These arguments were unavailing, and DEC Staff ultimately approved the use of gamma detectors as the principal screening device for radioactivity in drill cuttings.
Substandard landfill engineering
RFPLC also emphasized that the Chemung County Landfill emerged from a gravel pit in the 1960s, without bottom liners of any kind and without a siting study as would be routine today. It is located in an environmentally and historically sensitive area surrounded by farms, a growing rural population and the Newtown Battlefield, one of the most important pre-Revoutionary War battlefields in the nation. The landfill is few hundred feet from the Chemung River, in the Chesapeake Bay watershed, and a few feet from (if not directly over) an unconfined primary aquifer--that is, a groundwater source large enough to that it can be relied on as a supply of municipal drinking water.
If the landfill is allowed to continue accepting radioactive Marcellus Shale drilling wastes, a containment failure at the landfill could have catastrophic consequences. Even routine operations pose the risk of leaks and exposure of landfill workers and others who come in contact with wet, leaking drilling waste to excessive levels of radioactivity from concentrated, naturally occurring Radium-226 and -228 and their byproducts, such as radon, a known cause of lung cancer. It has long been acknowledged by EPA and others that landfills are not a permanent solution to waste management because all landfills will eventually leak.
Leachate from the Chemung County Landfill goes to the City of Elmira water treatment plant, which is unable to remove any radioactivity before discharging the treated wastewater to the Chemung River. DEC regulations allow the landfill to generate up to 20 gallons per acre per day of leachate, the liquid drained from the bottom of the landfill. The Chemung County Landfill is over 100 acres.
