AP Exclusive: Wyo. got EPA to delay frack finding

In internal emails that followed the Nov. 4 briefing, state officials expressed support for fracking as critical to oil and gas extraction, a $7.7 billion a year industry in Wyoming that accounts for 20 percent of the state's gross domestic product.



"The limiting of the hydraulic fracturing process will result in negative impacts to the oil and gas revenues to the state of Wyoming. A further outcome will be the questioning of the economic viability of all unconventional and tight oil and gas reservoirs in Wyoming, across the United States, and ultimately in the world," wrote Tom Doll, supervisor of the Oil and Gas Conservation Commission, in a long email that circulated among top state officials.
Wyoming's top state regulator of oil and gas development, including essentially all fracking in the state, Doll was a district manager for Tulsa, Okla.-based Williams Production Company until 2008.

The spark for Doll's missive was the closed-door meeting at Wyoming Department of Environmental Quality headquarters in Cheyenne two days earlier. EPA administrator Martin briefed Wyoming officials about what the EPA was about to announce based on its research in Pavillion. Doll took part by phone.

"Contaminants present at high concentrations in the deep monitoring wells are likely a result of hydraulic fracturing," read a "Key Findings" slide in an EPA PowerPoint shown at the meeting. Each slide was marked "Confidential--Do Not Disclose."
The public announcement more than a month later stated that the groundwater "contains compounds likely associated with gas production practices, including hydraulic fracturing."

The EPA also suggested at the private meeting that gas development likely had contaminated household well water in the Pavillion area but that current data did not definitively support such a link. The EPA has made no such claim in public to date.
Emails show that Mead sought to reach Jackson within hours. Mead confirmed that he got her to hold off on the findings report until state officials could review the data.
"When I talked to Lisa Jackson they were going to release the findings regardless. That wasn't even the question. The question was on the timing of it. We wanted a chance to see what are they basing this on," Mead told the AP.

"She said, `Well, maybe we can hold off a couple weeks to give you guys this data.'"

The Ohio Senate is calling for a fracking moratorium, when will Colorado?

COLUMBUS -- Democrats in the Ohio House have joined one of their minority party counterparts in the Ohio Senate in calling for a moratorium and increased regulations of an emerging means of extracting oil and gas from underground shale deposits.

Rep. Denise Driehaus, from Cincinnati, and Rep. Nickie Antonio, from the Cleveland area, hope to convince the Republican-controlled chamber to pass bills they are sponsoring to ensure horizontal hydraulic fracturing doesn't hurt groundwater supplies and areas around wells.

Driehaus introduced legislation Wednesday that would stop fracking activities until a federal study on the potential impacts is completed.

"Due to the potential environmental hazards and dangers to the surrounding land and drinking water, it is vital that we establish a moratorium on horizontal fracking of oil and gas wells while the U.S. Environmental Protection Agency completes a study on the relationship of hydraulic fracturing to drinking water resources," Driehaus said.

Antonio plans to introduce a bill that would establish additional reporting requirements for fracturing activities and the use and disposal of brine and wastewater used in the process.

Comparable legislation was introduced in the Ohio Senate last month by Sen. Mike Skindell, a Democrat from the Cleveland area.

The bills, however, are not expected to gain much support in the Republican-controlled legislature.
Rep. David Hall, a Republican from Millersburg who serves as chairman of the committee that would take up the bills, said Wednesday that the state already has stringent regulations to protect the environment. And he said hydraulic fracturing has been in use in the state for decades.

"I'll read the bills, but I don't see these things merit moving forward in the near future," Hall said.

Hydraulic Fracturing, or "Fracking," Colorado Legislative Council Publication


Number 11-8 A Legislative Council Publication July 25, 2011


HYDRAULIC FRACTURING
by Lauren Ris

Hydraulic fracturing, or "fracking," is a method
used by oil and gas operators to increase or open up
production on wells that would otherwise be
inaccessible. Oil and gas operators now use fracturing
on most wells in Colorado. Critics, however, express
concerns about the safety of this practice and its
potential impacts on groundwater and air quality. This
issue brief explains the fracturing process, federal and
state regulations, and an Environmental Protection
Agency (EPA) study of its risks.

Background

Fracturing process. Hydraulic fracturing involves
pumping a mixture of water, sand, and chemicals into
wells under high pressure to crack open tight
formations, thereby facilitating the flow of gas and oil
to the surface. The chemicals maximize the water
pressure, opening up cracks in the geologic formation.
Sand in the water keeps these cracks from collapsing
and allows the gas to flow to the surface.
When the process is finished, most of the fluid is
removed from the well lines, but some remains. The
remaining fluid is either dumped into a lined, open pit
to evaporate, is reinjected underground, or is trucked to
a disposal site.

Fracturing materials. Fracturing fluids are
primarily a mix of water and sand (99.5 percent). The
remaining 0.5 percent is comprised of chemicals and
lubricants, the exact recipes of which are proprietary
information held by the oil and gas companies and are
not made public.

According to the Ground Water Protection
Council, a nonprofit comprised of state regulatory
agencies, a typical fracture treatment will use low
concentrations of 3 to 12 additive chemicals,
depending on the formation being fractured. Each
component serves a specific purpose. For example,
water-based fracturing fluids mixed with
friction-reducing additives, called slickwater, allow
fracturing fluids and sand to be pumped to the target
zone at a higher rate than if water alone were used.
Biocides prevent microorganism growth, while oxygen
scavengers, and other stabilizers prevent corrosion of
metal pipes, and acids remove drilling and mud damage
within the near-wellbore area. The website
