Improving New York’s Proposed Hydraulic Fracturing Regulations

Around the country, states are taking a serious look at their regulations to manage shale gas development.  New York has the potential to be a leader among these states. Environmental Defense Fund (EDF) believes that strong regulations and aggressive enforcement is critical to protecting public health and the environment from high-volume hydraulic fracturing and other hydrocarbon extraction activities in New York State. To that end, we have submitted detailed comments on the New York State Department of Environmental Conservation (NYSDEC)’s proposed rules and permitting conditions for hydraulic fracturing. The NYSDEC can put New York at the forefront of safe and clean shale gas development by implementing our suggestions in several critical areas:

1)      Chemical Disclosure: Full public disclosure is rapidly becoming the industry norm across the country, but the proposed NYSDEC disclosure rules for chemicals used in the hydraulic fracturing process only covers chemicals with Material Safety Data Sheets (MSDS), thus failing to capture perhaps half or more of the chemicals used. This is especially problematic because MSDS only explore hazards in occupational settings and do not consider implications for public health or the environment. Further, the proposed rule only requires disclosure of additive products proposed to be used in hydraulic fracturing, as opposed to the chemicals actually used during the hydraulic fracturing process. EDF feels strongly that operators should disclose all hydraulic fracturing chemicals used on a well-by-well basis, posted on a searchable, publically accessible website.

2)      Well Construction: Properly constructed, tested and maintained wells are critical to protecting New York’s precious groundwater and surface water aquifers from contamination by drilling fluid, wastewater and natural gas seepage. The proposed well construction regulations and permitting conditions need improvement to meet industry best practice standards. Furthermore, some of the proposed rules represent potential safety hazards for well pad workers. A model regulatory framework EDF, and others, are developing could be used to greatly improve NYDEC’s proposed well construction regulations.  

3)      GHG Emissions/Methane Leakage: EDF is a leading advocate of strict standards on limiting methane emissions from natural gas production. Methane is a pernicious greenhouse gas, many more times more powerful than carbon dioxide.  To reduce the peak warming and improve air quality, it is critical to minimize the amount of methane vented or flared at the production site or leaked during storage and transmission. We strongly urge the NYSDEC to impose specific Green Completion and other emission-reducing requirements on operators, and to formulate hard emissions targets that provide incentives for operators to reduce methane leakage even further.

4)      Wastewater: Hydraulic fracturing produces huge volumes of potentially toxic and radioactive wastewater. New York recognizes this problem but does not seriously address the lack of capacity for processing or safely storing hydraulic fracturing waste materials within the state. Current technology does not allow for safe, cost-effective purification of hydraulic fracturing wastewater at treatment centers for re-introduction into the water system, and should be banned. Insofar as it appears that the final disposition of the bulk of the wastewater produced in New York will be trucked out of state to deep injection wells, the proposed regulations and permitting conditions must grapple with this expensive and perhaps unsustainable practice. Finally, since wastewater recycling will likely be the dominant treatment option undertaken by shale gas operators in New York, this practice needs to be more thoughtfully and transparently regulated.

5)      Phase-in: Even with the best rules on the books, it will take time to hire and train the necessary staff to implement and enforce the rules properly.  New York is essentially building a regulatory program from scratch.  EDF believes the NYSDEC should learn how to walk before it can run.  Our suggestion is that New York phase in the regulatory program region by region.  In this way, the state can be sure that the pace of drilling activity will not outpace its ability to adequately administer the regulations.  So, too, this phase-in approach will allow the state to acquire valuable experience in step-wise fashion. The key is not doing it quickly, but doing it correctly.

These and other adjustments to the proposed rules and permitting conditions are necessary to protect public health and the environment in New York. Shale gas extraction can be made safe through strong regulations and aggressive enforcement to protect communities. EDF is committed to working with the NYSDEC on these issues to produce the most responsible hydraulic fracturing regulatory framework in the nation.

State Of The Union Address: A Mixed Bag On Natural Gas

In President Obama’s State of the Union address last night, he laid out his plans for the expanded role that natural gas will play in the future. The President stated:

“We have a supply of natural gas that can last America nearly one hundred years, and my Administration will take every possible action to safely develop this energy. Experts believe this will support more than 600,000 jobs by the end of the decade. And I’m requiring all companies that drill for gas on public lands to disclose the chemicals they use.”

I am pleased to see a commitment to the full disclosure of hydraulic fracturing chemicals, but this is only the first step in getting the rules right for natural gas. As we discussed back in November, EDF President Fred Krupp sat on the Shale Gas Subcommittee of the Secretary of Energy Advisory Board (Subcommittee), which provided strong recommendations for strengthening environmental management in the shale gas industry and developing this abundant energy source in ways that safeguard public health and the environment. 

I would have liked to have seen the President speak directly to implementing the Subcommittee’s recommendations, beginning with the Department of the Interior (DOI). Simply committing to the disclosure of hydraulic fracturing chemicals isn’t enough. The recommendations included strict requirements for everything from well construction and the reduction or elimination of methane venting to groundwater protection to methane leakage and emissions flares, among others.  These recommendations are ready to be implemented, and DOI has an opportunity to demonstrate best practice in its leasing and oversight of unconventional natural gas development on federal lands.

The jury is out on whether states will embrace the Subcommittee’s recommendations and it will take a concerted effort on the part of organizations like EDF and concerned citizens to demand swift action to improve the quality and effectiveness of state regulations.  Implementation of the Subcommittee’s recommendations at the state level is a good place to start and some states are beginning to take a lead role.  For example, on the issue of disclosure, Colorado recently set the bar for requiring the full disclosure of all chemicals used in hydraulic fracturing by making this information available on a searchable database. On the other hand, states like New York have proposed weaker requirements, asking companies to disclose only half of the proposed additive products instead of the chemicals actually used in the hydraulic fracturing treatment. For these reasons, it is crucial that the DOI disclosure requirements set a leading example that will influence states to do better.  The DOI should start with Colorado, but can do even better.

Last night, the President demonstrated his commitment to domestic energy production through natural gas development and said that “America will develop this resource without putting the health and safety of our citizens at risk.” The federal government and the states have a shared responsibility to ensure that our air, land and water are safe wherever hydraulically fractured wells are drilled.

EPA’s Pavillion, WY Groundwater Contamination Study A Wake-Up Call

Today’s release of a draft US Environmental Protection Agency study on groundwater contamination around natural gas wells in Pavillion, Wyoming, should be a wake-up call to anyone who thinks public anxiety about shale gas development is overblown and unjustified. 

Based on the draft report, it seems pretty clear that hydraulic fracturing fluids, and other contaminants associated with natural gas production, found their way into Pavilion’s groundwater.  And it is not hard to see why.  The report reads like a primer on what NOT to do when developing unconventional gas.  It’s all here: poor cement quality, cement not injected to the proper depth to isolate the well from the groundwater, fracturing activity taking place in close proximity to the water table (in itself a questionable practice, but in this case, particularly egregious given the lack of cap rock between the zone of fracture and the groundwater), soil contamination around waste water pits indicating spills at the surface that migrated to groundwater and lack of clarity about what went down the well because of incomplete disclosure of the chemicals used in the fracturing process.

This draft report is Exhibit A on why stronger regulation and enforcement is necessary if the general public is EVER going to believe that shale gas development is a safe source of natural gas.  Indeed, the draft report says it best:

“Finally, this investigation supports recommendations made by the U.S. Department of Energy Panel (DOE 2011a, b) on the need for collection of baseline data, greater transparency on chemical composition of hydraulic fracturing fluids, and greater emphasis on well construction and integrity requirements and testing. As stated by the panel, implementation of these recommendations would decrease the likelihood of impact to ground water and increase public confidence in the technology.”

Having played a leading role in developing the DOE recommendations, we couldn’t agree more.   As this draft report makes clear, the time for action to improve regulation and enforcement is now.

DOE Roadmap Toward Cleaner Natural Gas Development – Sign Reads “Still Under Construction”

Today the Department of Energy’s Shale Gas Production Subcommittee released a final report that follows up on its earlier recommendations for increased oversight and transparency, assesses their implementation to date and lays out a roadmap for improvement.  The report proposes a focused set of steps for strengthening environmental management in the shale gas industry and developing this abundant energy source in ways that safeguard public health and the environment.  

The report is a call to action, stating “Americans deserve assurance that the full economic, environmental and energy security benefits of shale gas development will be realized without sacrificing public health, environmental protection and safety” and the Subcommittee believes that these recommendations, if implemented, would make real progress toward meeting these goals.  Time is of the essence, though, as the ramifications of inaction pose more risk every day.  

While much more remains to be done to ensure shale gas development is safe for people and the environment,  important progress is currently underway on federal, state and local levels.  The EPA, for example, has proposed rules to reduce air pollution from oil and gas development activities that, while needing improvement, are a critical first step.  Likewise, we’ve seen that states can move very quickly to update their oil and gas rules when they have a mind to.  For example, in only the past eleven months Arkansas, Texas, Montana and Louisiana have adopted requirements mandating the disclosure of chemicals found in hydraulic fracturing fluid.  And Colorado, New York, New Mexico and North Dakota have recently proposed requirements relating to fracturing fluid chemical disclosure.  In Pennsylvania, West Virginia and Ohio, legislatures have passed, or are in the process of debating, more stringent regulations on the exploration and production of natural gas.  

EDF is actively engaged across the country to further the safety and environmental protection of our natural resources wherever the production of natural gas is occurring.  It’s a long, cross-country road trip on highways still under construction.  We’re prepared for the long haul.

DOE Panel Offers Consensus Guidelines For Extracting Natural Gas Safely

Natural gas plays an important role in our nation’s economy, and has the potential to help reduce greenhouse gas pollution, bolster energy security, and reinvigorate domestic manufacturing.  Unfortunately, these potential benefits are jeopardized by inconsistent and often poor natural gas production practices, leading to real threats to public health and the environment, that understandably engender community opposition to natural gas production. 

To say the natural gas industry has a credibility problem is an understatement.  If the recent spate of critical articles in the New York Times escaped your attention, than perhaps you saw this recent bit on the Colbert Report, which demonstrates, among other things, that the general public has little understanding for the complex issues surrounding shale gas development, and the industry has been doing little to engage them in a serious way.  The Colbert bit is funny, but the need to get the shale gas issue right is no joke.

In March, President Obama directed Energy Secretary Steven Chu to appoint a group of energy and environmental experts to study the issue.  EDF President (and my boss) Fred Krupp was appointed to the panel.  During 90 days of intensive investigation and deliberation, the panel, chaired by MIT professor John Deutch, held a series of public hearings. They heard from industry officials, environmental leaders, federal and state regulators, scientists and others.  They visited well sites to see drilling and production first hand.   They held a public meeting in southern Pennsylvania to hear directly from people who are living with intensive shale gas development – both the good and the bad.  Supporters and opponents packed the auditorium and told stories about how the shale gas boom had affected them. For some, it had provided an economic lifeline. For others, it had made life a nightmare. 

And today, after much study and deliberation, the committee has issued a report with some very specific recommendations which, if implemented, could materially reduce the risks to public health and environment from shale gas development and begin to build public trust. 

The report calls for increased oversight: robust enforcement practices and modernized rules to safeguard communities and improve communication between state and federal regulators. The report makes it clear that “effective and capable regulation is essential to protect the public interest. The challenges of protecting human health and the environment in light of the anticipated rapid expansion of shale gas production require the joint efforts of federal and state regulators. This means that resources dedicated to oversight of the industry must be sufficient to do the job and there is adequate regulatory staff at the state and federal level with the technical expertise to issue, inspect and enforce regulations.”

The report also makes clear that regulation alone will not be enough.  It calls for the full public disclosure of all chemicals used in the process of hydraulic fracturing.  It calls for gathering the data necessary to determine whether, and to what degree natural gas provides greenhouse gas benefits when substituted for coal or oil in energy production or transportation.  It recommends that the industry get its own house in order by organizing itself to identify and share best practices across the industry with a relentless focus on continuous improvement in reducing air and water pollution and other environmental harms. 

These recommendations won’t solve all problems, and there is much work to be done simply to make these recommendations a reality, but today’s report is an important step in getting beyond the comedy bits and headlines to focus on those measures that can make a material difference in improving public health and the environment.

Poor Well Construction Is The Culprit

The iconic image of shale gas development is the flaming faucet featured in Josh Fox’s recent movie, Gasland.  Inquiring minds want to know: “how does methane get into a water faucet, and is hydraulic fracturing of shale to blame?”  A Duke University study released this week sheds light on these important questions.

The study, performed by three researchers affiliated with Duke University’s Biology Department and Nicholas School of the Environment, examined 60 drinking water wells in northeastern Pennsylvania and southern New York, the northern tier of the geological formation known as the Marcellus Shale, ground zero for aggressive shale gas development in the eastern United States.  And sure enough, methane concentrations were detected in 51 of the 60 wells, with substantially higher concentrations of methane found in drinking water wells closest to active natural gas production sites.  While there are numerous instances of methane migrating into drinking water supplies through naturally occurring fissures, even in the absence of gas drilling, this study makes a pretty compelling case that natural gas production can create a problem where none ever existed, or certainly make an existing problem worse.

But, on the question of whether hydraulic fracturing is to blame, the evidence is less compelling.  Indeed, the fact that methane was found in water wells, but the chemicals used to fracture the shale were not, suggests that fracturing may have had nothing to do with the unwanted migration.  The culprit, it would seem, are not fissures created by the fracturing of the shale, but rather poor well construction – specifically, failures in the cement casing surrounding a well – which enable the natural gas to migrate into the water table as it moves its way up the well to the surface.  The authors have noted that “leaky casings” are the most likely cause of problems.

Poor well construction is a problem that can occur anywhere, whether production is aided by hydraulic fracturing or not.  For all of the attention Gasland’s flaming faucet has brought to the hydraulic fracturing debate, this study points our attention to the role that better well construction and design practices can play in reducing the very real problem of methane contamination of well water.
