Special DISCOUNT rate of $70 for college students and young adult leaders are available (though this does not include meals.) Limited number of such scholarships are available. Contact Carol Gonzalez to request the discount.

One of the Eight Workshops Available:

Friday, February 25 at 2:00 pm – Holy Water, Sacred Breath: Eco-Justice & Creation Care: “Do unto those downstream what you wish those upstream had done to you”

Dr. Conrad Dan Volz and Mark Dixon will present and host a conversation on issues around water (the new oil) and Marcellus Shale drilling, an urgent regional issue with links to national & global energy, economic, and environmental issues. The concerns surrounding gas and oil extraction and related water contamination are directly related to both intra- and inter-state political problems and open conflict around the world, making this a serious issue for faith groups interested in environmental justice and peace. Climate change, Transition Town, and other related topics will be included as we connect the dots in our search for sustainability.

Oil, Natural Gas, and Natural Gas Fluids Drilling and Production in the Inland United States Waters of the Great Lakes?


By: C. D. Volz, DrPH, MPH
Director and Principal Investigator of the Center for Healthy Environments and Communities

Is it possible that there will, in the future, be offshore oil and gas platforms in the Great Lakes regions of the United States? The answer is that it has already occurred in Lake Michigan and certainly could be radically expanded with new advances in directional drilling and hydrofracturing of unconventional oil and gas reserves. Oil and gas drilling in the Great Lakes was allowed by the State of Michigan but new drilling was subsequently banned by the state legislature. The issuance of new permits for new drilling in the Great Lakes was banned by the Energy Policy Act of 2005 (P.L. 109- 58, §386). Canadian law though permits onshore oil and gas drilling under the Great Lakes and offshore gas drilling in the Great Lakes (see Congressional Research Service Document, Drilling in the Great Lakes: Background and Issues, 2006.

The U.S. Geological Survey (USGS) completed an assessment of the undiscovered oil and gas potential of the U.S. portions of the Appalachian Basin and the Michigan Basin in 2002 and 2004, respectively The USGS has done an assessment of oil and gas reserves under US portions of the Great Lakes and reports mean levels of recoverable oil, natural gas, and natural gas liquids at 311.71 million barrels of oil (MMBO), 5,228.71 billion cubic feet of gas (BCFG) (equal to 5.228 trillion cubic feet of gas), and 121.68 million barrels of natural gas liquids (M MBNGL), respectively. There have been 8-eight petroleum systems identified underlying United States portions of the Great Lakes. These are the;

  1. Precambrian Nonesuch TPS
  2. Ordovi¬cian Foster TPS
  3. [Ordovician] Utica-Lower Paleozoic TPS
  4. Ordovician to Devonian Composite TPS
  5. Silurian Niagara/Salina TPS
  6. Devonian Antrim TPS
  7. Devonian Shale-Middle and Upper Paleozoic TPS
  8. Pennsylvanian Saginaw TPS.

Each of the above systems is named for the source rock(s) of that system and there is only one source rock for each of the listed systems except the Ordovician to Devonian Composite TPS, which is a composite petroleum system. The Ordovician to Devonian Composite TPS is made up of one or a combination of the following source rocks; the Ordovician Collingwood Shale, Devonian Detroit River Group, and the Devonian Antrim Shale. For more information, see the complete USGS fact sheet, Undiscovered Oil and Gas Resources Underlying the U.S. Portions of the Great Lakes, 2005, Fact Sheet 2006–3049, April 2006.

GASP Position on DEP Air Studies

What We Can Learn From Pennsylvania DEP’s Marcellus Air Monitoring Studies

By Joe Osborne, Legal Director, Group Against Smog and Pollution

Last week the Pennsylvania Department of Environmental Protection released a study of air quality around Marcellus Shale operations in northeastern Pennsylvania. Here are some typical headlines from articles on the study: “Pa. DEP study finds Marcellus air emissions OK,” “DEP Says Air Near Marcellus Drilling Sites Is Safe,” or even “DEP finds no health threat from Marcellus air emissions.”

If those headlines are accurate, why do GASP and other environmental organizations keep going on and on and on and on about the massive quantities of air pollution that result from natural gas production? Both can’t be true, right? So what explains the discrepancy?

Limitations of the DEP Studies

First, as DEP acknowledges, the data collected during this study simply is not sufficient to support the bold, sweeping claims found in headlines like those I listed above. This study, as well as a similar study from southwestern Pennsylvania.

DEP released last fall, selected a few sites where natural gas activity was occurring and conducted air monitoring at each of these sites for no more than 5 days. The goal was to determine if any of 44 specific pollutants DEP selected were present in the atmosphere in sufficient concentrations that breathing that air for a short period (generally somewhere between 1 hour and 24 hours) would pose a threat to human health. So already some of the studies’ limitations are clear: between these two studies DEP has conducted monitoring at only 8 natural gas sites, never monitored at any one site for more than 5 days, and ignored the risks of long-term exposure to these pollutants. Are these studies useful? Absolutely, but they don’t justify a sweeping conclusion that natural gas operations pose no risk to our air.

In fairness to the journalists who reported on the DEP’s study, I should also note that the majority of news stories on the DEP’s studies also mention these limitations, but you have to make it most of the way through the typical article before they’re mentioned. And while I’m being fair, I should also mention that DEP acknowledges these limitations in the executive summaries to both of these studies (though press releases and public statements are another matter, which I’ll get to in a moment):

“Due to the limited scope and duration of the sampling and the limited number of sources and facilities sampled, the findings only represent conditions at the time of the sampling and do not represent a comprehensive study of emissions. While this short-term sampling effort does not address the cumulative impact of air emissions from natural gas operations . . . the sampling results do provide basic information on the type of pollutants emitted to the atmosphere during selected phases of gas extraction operations in the Marcellus Shale formation.”

There are also problems with these studies that DEP does not acknowledge… Read more by GASP

EPA Releases Draft of Hydraulic Fracturing Study Plan

The Environmental Protection Agency has submitted a draft of its Hydraulic Fracturing Study Plan, which is to be reviewed by the Science Advisory Board (SAB), a group of independent scientists that works with the agency.  According to the EPA’s news release, the focus of the study will be the lifespan of the water, from extraction to disposal of the waste water.

The 140 page draft has been made to the public. The SAB is scheduled to review the plan March 7th and 8th, and the plan will likely be edited based on their input.

Initial results of this study are expected by 2012, with an additional report due by 2014.

Salt mining and gas production: how are they related?


This article has been archived and is provided for reference purposes only.

By Karen Edelstein, New York State FracTracker Liaison

One of New York State’s important industries has been the production of salt. Thick, uniform layers of salt were laid down hundreds of millions of years ago when ancient seas covered our region. When the seas receded or dried up, these salt beds were left behind. Beginning in 1812, salt production began along the shores of Onondaga Lake in Syracuse, New York, “The Salt City.” By the mid- to late-1800s, large-scale salt mining operations sprang up across the state; salt was discovered in the strata below Watkins Glen, NY in 1882. Using the process of solution mining, salt was brought to the surface by drilling wells into the Devonian rock strata. Hot water was pumped into the hole, and the resulting brine was brought to the surface to be evaporated. Over time, each bore hole enlarged into a cavern as more of the solid salt layer was dissolved and pumped out. Over time, over 600 brine solution wells have been drilled in New York State.By Karen Edelstein, New York State FracTracker Liaison

Today, salt is mined through more modern-style solution mining that uses sonar and other technologies to predict the inner dimensions and stability of the caverns created by the solution mining. In addition, salt is extracted from the ground as solid halite (primarily for road salt) at the Cargill Salt facility in Lansing, NY, along the shores of Cayuga Lake. The Cargill mine in Lansing is the deepest rock salt mine in North America, with more than 40 miles of horizontal tunnels all 2300 feet beneath Cayuga Lake. 2.5 million tons of rock salt is mined from this facility each year.

In and around Watkins Glen, NY, there are several salt mining operations, all of which are removing salt as brine. The combined layers of nearly pure salt beneath Watkins Glen are about 450 feet thick, and occur between 1500 and 1900 feet below the surface. The large plant at the south end of Seneca Lake is owned by Cargill. Further up the west side of the lake is the US Salt facility. Along this part of the Seneca Lake shore there are 62 brine wells, all but 6 of which are plugged and abandoned. Some of these abandoned wells date from prior to 1900.

But how is salt production tied to gas production? Brine wells have an additional use beyond the production of salt. They are also used for the storage of liquid petroleum gas. Because in its gaseous state, hydrocarbon fuel takes up a lot more space than it does as a liquid, the gas is pressurized for storage, and held underground until it’s ready to be used.

The proposed LP gas storage site, owned by the Kansas City-based company Inergy, is less than 3 miles north of Watkins Glen (population 2200), and will hold up to 2.1 million barrels of LP gas, pressurized at about 1000 psi. The property is in close proximity to existing gas and hazardous liquid pipeline infrastructure.

Depending on demand, brine in the well will be drawn down to make room for the additional storage need, and pumped back down during the months of less demand. Critics of the project are strongly concerned about the construction of the impoundment that will contain the brine. Currently, the planned 92-million-gallon (2.19 million barrel) storage lagoon—1000 feet long, 382-608 feet wide and 32 feet deep, will be perched on a steep slope above Seneca Lake, the largest and deepest of the Finger Lakes. A 50-foot high wall on the downward sloping (8-12% grade) hillside will contain the brine.

A recent public information meeting on the project was held in Ithaca, NY on January 27, with presentations by Peter Mantius, a locally-based investigative journalist, and Thomas Shelley, a retired chemical safety and hazardous materials specialist. Mantius, a 3-time Pulitzer Prize nominee, lives in the Town of Burdett, just across Seneca Lake from the proposed LP gas storage facility. Finger Lakes LPG Storage, LLC proposes to construct and operate a new underground liquefied petroleum gas (LPG) facility there for the storage and distribution of propane and butane. The 576-acre site is located on NYS Routes 14 and 14A west of Seneca Lake in the Town of Reading, New York.

Mantius, who published his findings in October 2010 in the online blog DCbureau.org, noted that while LP gas is commonly stored underground, “…salt caverns have been more prone to catastrophic accidents than the other more common types of underground storage for natural gas or liquified petroleum gas, or LPG. A 2008 report by the British Geological Survey cited several salt cavern accidents, including an explosion caused by an LPG leak in Texas that registered 4 on the Richter Scale and killed three people.”

The New York State Department of Environmental Conservation determined that a draft supplemental environmental impact statement (DSEIS) would be necessary for this project, and in advance of that process, published a draft scoping outline to guide the DSEIS on January 5, 2011. Interestingly, at least 2 individuals who own property adjacent to the proposed facility had only learned of the project within days of the January 27th meeting in Ithaca, barely affording them the opportunity to comment on the project within the allotted time window. The public comment period on the scoping document ended on January 31, 2011.

Clearly, there are concerns about catastrophic failures of both the brine pond impoundment, and the stability of the pressurized cavern itself. Education about the project has been strikingly slow to permeate the surrounding rural community and nearby Village of Watkins Glen. We’ll keep following this issue as it develops.

When Messages are in Opposition, Risk Communication Difficult

By Samantha Malone, MPH, CPH – Communications Specialist, Center for Healthy Environments and Communities of the University of Pittsburgh Graduate School of Public Health (GSPH); Doctoral Student, GSPH

Two reports were issued yesterday by credible sources regarding the safety of natural gas drilling in shale formations. The one was issued by the Pennsylvania Department of Environmental Protection (PA DEP) on the air emissions from natural gas operations. The other by the House Energy Commerce Committee focused on the use of diesel fuel in hydraulic fracturing fluid. While these reports do not contradict one another, they certainly do not contribute to an overall consensus on the public safety of shale gas extraction.

Report 1 – PA Department of Environmental Protection

The PA DEP’s report was based on a four-week air quality study that they conducted in northeastern PA near Marcellus Shale natural gas operations. This report states that the emission levels they surveyed would not constitute a health concern for nearby residents, acknowledging that the study’s purpose was not to address the cumulative impacts that could result from long term exposure.

Report 2 – House Energy and Commerce Committee

The Energy and Commerce Committee within the House of Representatives sent a letter to the Environmental Protection Agency’s Administrator, Lisa Jackson, stating that between ’05 and ’09 oil and gas companies injected over 32 million gallons of diesel fuel or hydraulic fracturing fluids containing diesel fuel in wells in 19 states. This letter noted that at no point in time were these companies officially permitted to use diesel fuel in the hydraulic fracturing process – citing the behavior as a violation of the Safe Drinking Water Act.

The Message

The intention for this post is not to debate whether air contamination is worse than ground or water pollution, whether one report is right/wrong, or to discuss how difficult it is to accurately measure air emissions when companies know when and where you are testing. The true intention of writing this is to stress that the opposing reports only stand to ‘muddy the water’ on America’s viewpoint of the issue. Risk communication is hard enough to do properly without such inconsistency. The fact that these – and many other credible sources – cannot agree on whether natural gas drilling poses an environmental or public health threat further demonstrates that additional, unbiased research should be conducted.

Tracking the Effects on Farms

By Samantha Malone, MPH, CPH – Communications Specialist, Center for Healthy Environments and Communities (CHEC), University of Pittsburgh Graduate School of Public Health (GSPH); and Doctorate of Public Health (DrPH) Student, GSPH

If done improperly (or in excess), shale gas drilling has the potential to contaminate ambient air, surface water, drinking water, and/or ground water. A healthy agricultural system relies upon all of those media in varying degrees.On any given day, I receive roughly 50 emails from people concerned about the effects of natural gas drilling. Check out this document as an example. The topics of conversation are incredibly diverse, and yet the discussion surrounding the effects that drilling may have on our local farms is occurring more and more frequently. One of the reasons for this ‘boom’ in concern about our farms, in my opinion, is that the scientific evidence that connects drilling and hydraulic fracturing to the potential contamination of the food supply is lacking – while the anecdotal evidence is not.

As a result, people have even begun to compile ‘evidence’ suggesting that drilling has affected local agriculture, or will. I believe this is a research issue of great importance, and would welcome suggestions of additional resources (either pro or con) from readers. What are the concerns or questions that people have, you might ask? In a very simplified nutshell:

  • How is the health of farm animals affected by industrial processes occurring nearby? (e.g. by accidentally drinking frac pond fluids or by the stress caused by noise pollution)
  • How will shale gas drilling and forced pooling affect farmers who are applying for or trying to keep their organic farm certifications?
  • Do the communities burdened with gas drilling truly ‘reap’ the rewards?
  • Will the royalties some farmers receive cause them to produce more or less food on their property? And as a result, will access to local and fresh foods improve or decline? (Of the many benefits, access to local, fresh foods improves health by minimizing truck traffic used to ship the products, reducing farming’s carbon footprint – which affects climate change, and providing access to seasonal foods so that consumers do not rely upon packaged, nutritionally deficient food.)
We are just beginning to understand the breadth and depth of this issue. Unfortunately, some effects caused by events today may not surface for years to come. That is a major challenge to epidemiology. We at CHEC, including many other organizations across the Marcellus Shale region, are working to conduct baseline and field research, identify areas of key concern, and prevent negative health and environmental consequences to the highest degree possible. If you are interested in learning more, please email us at chec@pitt.edu.Below is one snapshot created using FracTracker’s DataTool that highlights some of the issues raised by this new industry – and how it may affect our agricultural system:
