Bossert is the former senior vice president of regulatory and government affairs for Chief Oil & Gas LLC and ex-counsel to the Pennsylvania Department of Environmental Protection. He will report to Scott Roy, former deputy chief of staff to Pennsylvania Gov. Ed Rendell (D), who left office in 2009. 7 Regulations Without Strict Enforcement Are Just Words on Paper Feb 22, 2013 - In the third day of budget hearings Thursday, …Sen. Jim Ferlo, D38, voiced surprise that nine of every 10 violations cited by DEP inspectors at Marcellus Shale gas wells in 2011 resulted in no fines. “How do you reconcile that?” the Pittsburgh lawmaker asked. “The idea of an issuance of a notice of violation is not to issue a fine. The idea is to bring conduct which is potentially volatile to the attention of the operator so the operator can do something about it,” Krancer said. But that wasn’t enough for Ferlo, who is a member of the Senate Environmental Resources & Energy Committee. “You’re the secretary of DEP and the citizens are demanding that there be proper enforcement and proper citations to correct the behavior of an industry that, in my opinion, has run amok, despite your perception of the industry. Citizens feel very shortchanged right now,” Ferlo said. “I’m sorry for that perception on your part. I think it’s an incorrect perception,” Krancer responded. http://www.phillyburbs.com/news/local/courier_times_news/dep-secretary-krancer-hit-on-marcellus-shale-smallmouthbass/article_446821c4-2d21-55d3-a497-d995674c994a.html 8 A Dispassionate View of the Industry. “…oil and gas companies are not in business to steward the environment, save the family farm or pull depressed areas out of economic decline. If these things should by chance happen, they are merely peripheral to the primary mission of the companies and certainly were never considered in corporate exploration and production plans. Further, given shales’ steep declines and thus limited lives, such benefits will be short-lived as well. It would be the height of naïveté to assume that such companies have altruistic intent towards a region or its residents. They do not. Oil and gas companies are in business to extract hydrocarbons as cheaply and efficiently as possible and get them to the customer that will pay the highest price. If they can shave dollars off already thin margins by refusing to use pollution control devices then that is precisely what they will do if it is not mandated, regardless of whether this will increase costs for a region due to pollution or negatively impact other industries. Even though pollution and degradation involve real costs, they are not borne by the industry that perpetrates them in today's economic accounting. This is especially true of the oil and gas industry as they are exempt from federal environmental protection statutes.” Rodgers, Energy Policy Forum, February 2103 9 Why Is High-Volume Fracing from Long Laterals in Shales a Higher Risk to Public Health? • Requires much higher well density, many wells per square mile. • Requires much more industrial development over large areas, heavy equipment operating 24/7/365. • Requires much higher volumes of fracing fluid, millions of gallons per well. • Produces much higher volumes of waste fluids and solids containing hazardous materials: frac fluid chemicals, heavy metals, NORMS, NOx, VOC’s. • Produces higher volumes of fugitive emissions of methane. 10 Why Is Slickwater, High-Volume Fracing from Long Laterals a Higher Risk to Public Health? • As number of wells and volumes of waste increase, probability of accidental releases of hazardous materials into air and groundwater increases. • Cumulative effects on air and water and health from these and from purposeful emissions into the atmosphere and releases into groundwater are unknown. • Increased production, processing, storage, transportation and burning of natural gas and its liquid companions (e.g. ethane, propane, butane) increases emission of GHG’s, exacerbates climate change 11 GOOD MECHANICAL INTEGRITY CONDUCTOR PIPE FRESH WATER AQUIFER ZONE SURFACE CASING PRODUCTION CASING SHALLOW PRODUCING ZONE INTERMEDIATE PRODUCING ZONE 12 TARGET PRODUCING ZONE CEMENT CHANNELING CONDUCTOR PIPE PRESSURE BUILDS UP FRESH WATER AQUIFER ZONE SURFACE CASING CEMENT CASING FORMATION PRODUCTION CASING SHALLOW PRODUCING ZONE INTERMEDIATE PRODUCING ZONE 13 TARGET PRODUCING ZONE LEAK THROUGH CASING CONDUCTOR PIPE PRESSURE BUILDS UP FRESH WATER AQUIFER ZONE SURFACE CASING FORMATION CASING PRODUCTION CASING SHALLOW PRODUCING ZONE INTERMEDIATE PRODUCING ZONE 14 TARGET PRODUCING ZONE INSUFFICIENT CEMENT COVERAGE CONDUCTOR PIPE PRESSURE BUILDS UP FRESH WATER AQUIFER ZONE SURFACE CASING PRODUCTION CASING SHALLOW PRODUCING ZONE INTERMEDIATE PRODUCING ZONE 15 TARGET PRODUCING ZONE Surface Impacts on Health/Environmental: Pads, Pipelines.

Paper: Our Cornell Colleagues’ Criticisms of Our 1st Paper 1) a physical argument that large flows of gas are not possible while frac fluids fill the well; 2) an assertion that venting of methane to the atmosphere would be unsafe; 3) a statement that we incorrectly used data on methane capture during flowback to estimate venting; 4) an assertion that venting of methane is not in the economic interests of industry. 44 Our 2nd Paper Refutes These Arguments, And Provides New Supporting Data 1) a physical argument that large flows of gas are not possible while frac fluids fill the well. Large flows do occur because flowback is twophase, not dissolved gas; and there is 10 to 100 times more flowback from shale wells than from conventional wells. 45 Our 2nd Paper Refutes These Arguments, And Provides New Supporting Data 2) an assertion that venting of methane to the atmosphere would be unsafe. EPA (2011) reports 85% of flowback gas from unconventional wells is vented, less than 15% flared or captured; methane density only 58% that of air and is extremely buoyant when vented (recall video); venting is NOT illegal:“excess gas encountered during drilling, completion or stimulation shall be flared, captured, or diverted away from the drilling rig in a manner than does not create a hazard to the public health or safety” 46 Our 2nd Paper Refutes These Arguments, And Provides New Supporting Data 3) a statement that we incorrectly used data on methane capture during flowback to estimate venting. We used data on captured gas as a surrogate for vented emissions, similar to EPA (2010) because industry does not measure or estimate the gas that is vented during flowback. Most data we used were reported to the EPA as part of their “green completions” program, and they provide some of the very few publicly available quantitative estimates of methane flows at the time of flowback. (Note new EPA regulations start in 2012). 47 Our 2nd Paper Refutes These Arguments, And Provides New Supporting Data 4) an assertion that venting of methane is not in the economic interests of industry. According to EPA (2011b), break-even price at which the cost of capturing flowback gas equals market value of captured gas is slightly under $4/Mcf.

From late 2007 to late 2010, one well integrity violation was issued for every six deep injection wells examined — more than 17,000 violations nationally. More than 7,000 wells showed signs that their walls were leaking. Records also show wells are frequently operated in violation of safety regulations and under conditions that greatly increase the risk of fluid leakage and the threat of water contamination. Structurally, a disposal well is the same as an oil or gas well. Tubes of concrete and steel extend anywhere from a few hundred feet to two miles into the earth. Operators are required to do so-called "mechanical integrity" tests at regular intervals, yearly for Class 1 wells and at least once every five years for Class 2 wells. In 2010, the tests led to more than 7,500 violations nationally, with more than 2,300 wells failing. In Texas, one violation was issued for every three Class 2 wells examined in 2010. http://www.propublica.org/article/injection-wells-the-poison-beneath-us 55 56 Industry Performance in NYS: Plugging Abandoned Wells “…of 48,000 abandoned oil and gas wells total, 13,000 were plugged and approximately 35,000 were not plugged as of 1994 …” Bishop, HISTORICAL ANALYSIS OF OIL AND GAS WELL PLUGGING IN NEW YORK: IS THE REGLATORY SYSTEM WORKING?, NEW SOLUTIONS, 23(1) 103-116, 2013 57 In the large U.S plays, shale gas development has only just begun, and it requires a large number of large, multi-well, clustered pads and significant ancillary infrastructure 58 Wellbore Integrity: Recent Operator Performance in the Pennsylvania Marcellus Play 1,609 wells drilled in 2010. 97 well failures. 6% rate of failure. 1,972 wells drilled in 2011. 140 well failures. 7.1% rate of failure. Palepko data 1346 wells drilled in 2012 120 well failures. 8.9% rate of failure. Consistent with previous industry data, and not improving. 59 What Are the Implications of Leaking Wells? Each leaking well has the potential for contamination of one or more private or public water sources, and will leak volatile organic compounds into the atmosphere. 60 High Volume Hydraulic Fracturing Proposed Regulations 6 NYCRR Parts 550-556, 560 Among My Comments and Recommendations Recommendation: As a minimum, DEC should perform and publish its own statistical analysis of documented incidents of hydrocarbon migration into underground sources of drinking water in the Marcellus play in Pennsylvania, and develop its own prediction of immediate and long-term rate of well failures for shale gas development in New York. Recommendation: It is not possible to perform a rational cost-benefit analysis of shale gas development in New York without a science-based, probabilistic estimate of the number of expected well contamination incidents due to faulty wells. DEC should estimate the cost associated with mitigation of such contamination in its economic analysis of shale gas development. Each leaking well will, unless completely stopped from leaking natural gas, contribute to methane emissions and exacerbation of climate change. DEC should estimate the impact of such emissions on NYS goals for reduction of CO2eq . 61 Our Energy Plan for New York State Jacobson et al., Energy Policy, Feb. 2013 62 Natural Gas Price is Volatile and Will Inevitably Rise, As Will the Price of Oil $3.96 Today 63 We Own the Wind, the Sun, the Water: Their Fuel Cost is Zero.

Ours is an industry that is built on technology, it's built on science, it's built on engineering, and because we have a society that by and large is illiterate in these areas, science, math and engineering, what we do is a mystery to them and they find it scary. And because of that, it creates easy opportunities for opponents of development, activist organizations, to manufacture fear.” Rex W.

We have spent our entire existence adapting, OK? So we will adapt to this. Changes to weather patterns that move crop production areas around -- we'll adapt to that. It's an engineering problem, and it has engineering solutions. And so I don't -- the fear factor that people want to throw out there to say we just have to stop this, I do not accept. I do believe we have to -- we have to be efficient and we have to manage it, but we also need to look at the other side of the engineering solution, which is how are we going to adapt to it. And there are solutions. It's not a problem that we can't solve.” Rex W. Tillerson, Chairman and CEO, Exxon Mobil Corporation June 27, 2012 Council on Foreign Relations 70 EXXON Mobil CEO on Journalists “…But this is an ongoing dialogue I've been having with people in your profession now for some time; that for whatever reason, a large number of people in the journalism profession simply are unwilling to do their work. They're unwilling to do the homework. And so they get something delivered to them from the manufacturers of fear; it makes a great story. I mean, it – I mean, it does. It makes a great story. People love that kind of stuff. The consuming public loves it, because it goes to what, you know, their fears are.” Rex W. Tillerson, Chairman and CEO, Exxon Mobil Corporation June 27, 2012 Council on Foreign Relations 71 Exxon Mobil CEO: Farmer Joe Is a Liar “…There are a lot of sources of science-based information. There are a lot of sources that can debunk claims that are made specific -- you know, specific examples. Farmer Joe lit his faucet on fire, and that's because there was gas drilling going on, you know, in his back porch. And we can go out there and we can prove with science that that is biogenic gas; it's been in the water table for millions of years; it finally made its way Farmer Jones' faucet, it had nothing to do with any oil and gas activities. And part of when you're dealing with the subsurface strata is you've got to -- you got to understand that Mother Nature has done a lot of things in the subsurface that have nothing to do with anything man has done. And it changes. It moves around all the time. So what once was will change.” Rex W. Tillerson, Chairman and CEO, Exxon Mobil Corporation June 27, 2012 Council on Foreign Relations 72 EXXON Mobil CEO Correct on Shale Gas Economics “…And what I can tell you is the cost to supply is not $2.50. We are all losing our shirts today. You know, we're making no money. It's all in the red.” “The higher volumes are not only the result of drilling in the higher Btu area, but are also the result of drilling longer laterals and completing them with more frac stages. We’ve also experimented with reduced cluster spacing, decreasing the frac interval from 300 feet to 150 to 200 feet, all of this looks very promising.” Once we extract ethane beginning late next year, this will further enhance the economics.” 73 74 75 76 77 78 79
