Hydro fracturing is a profitable method of natural gas extraction that uses large quantities of water and chemicals to free gas from underground rock formations. But New York City’s concerns that the practice would threaten its water supply have slowed a juggernaut that has been sweeping across parts of the northeastern United States.

The highly productive method of natural gas extraction known as “hydro fracturing” has spread rapidly across the United States in recent years, opening up vast new reserves in Texas, Wyoming, Pennsylvania, and other states.

Last fall, however, the process — also known as “fracking” — ran headlong into opposition from New York City. And for now at least, stiff resistance from the city, which fears the contamination of its pristine water supply in upstate New York, seems to have slowed the momentum behind this highly touted — and highly controversial — drilling technique.

When New York State’s environmental agency came out with a draft environmental review of drilling in the Marcellus Shale in September, it set off a flurry of action for environmentalists, industry advocates and the general public.

People were given 30 days — later extended to 90 — to digest the highly technical 800-plus-page document and submit comments. They could also voice their opinions at four public hearings.

At stake was the future of gas drilling in New York’s portion of the Marcellus Shale, which could produce vast amounts of natural gas, but which some residents fear also could contaminate drinking water sources and the air.

Since the comment period ended on Dec. 31, New York’s Department of Environmental Conservation has been assembling and evaluating the public’s response, which included a stinging analysis of the plan by the U.S. Environmental Protection Agency. DEC officials aren’t saying when the final version of the review will be unveiled, but two department representatives, Yancey Roy and Maureen Wren, did agree to walk us through the process. (more…)

U.S. Interior Secretary Ken Salazar said his department will no longer be the “handmaiden” of the oil and gas industry and will conduct tougher environmental reviews of proposals to drill on public lands. Criticizing the Bush and administration for turning federal lands into a “candy store” for the petroleum industry, Salazar told reporters, “The difference is in the prior administration the oil and gas industry essentially were the kings of the world.” He said lax leasing policies “ran afoul of communities, carved up the landscape, and fueled costly conflicts that created uncertainty for investors and industry.”

Salazar said he was ordering federal land managers to get out from behind their desks and to visit proposed leasing sites to evaluate the environmental and social impacts of drilling. The stricter review process would not reduce the amount of oil and gas extracted from federal lands, Salazar said, but would ensure that drilling was done in a more responsible manner. (more…)

As environmental concerns threaten to derail natural gas drilling projects across the country, the energy industry has developed innovative ways to make it easier to exploit the nation’s reserves without polluting air and drinking water.

Energy companies have figured out how to drill wells with fewer toxic chemicals, enclose wastewater so it can’t contaminate streams and groundwater, and sharply curb emissions from everything from truck traffic to leaky gas well valves. Some of their techniques also make good business sense because they boost productivity and ultimately save the industry money — $10,000 per well in some cases.

A $17 million renewable energy project designed to tap into the earth’s heat more than 2 miles deep has been suspended because of difficulty drilling through rock formations.

The project, run by AltaRock Energy and partially funded by Google, was designed to drill down to about 12,000 feet, fracture rock at the bottom of the hole, and then circulate water to create steam.

But the company reported that it had encountered “anomalies” in the rock that had prevented it from drilling deeper than 4,000 feet.

For the first time, scientists have discovered chemicals used in a controversial natural gas drilling technique in water wells near the gas sites.

Scientists for the Environmental Protection Agency (EPA), testing wells near a major gas drilling area in Wyoming, have found traces of drilling chemicals in three wells, and other contaminants — including oil, gas, and heavy metals — in 11 of 39 wells recently tested, according to the Web site Pro Publica.

The chemicals are used in a process called hydraulic fracturing, in which drilling fluids and sand are injected under high pressure to break up rock and release gas.
