EPA Sees Risks to Water, Workers in New York Fracking Rules

New York's emerging plan to regulate natural gas drilling in the gas-rich Marcellus Shale needs to go further to safeguard drinking water, environmentally sensitive areas and gas industry workers, the U.S. Environmental Protection Agency has informed state officials.

The EPA's comments, in a series of letters this week to the state's Department of Environmental Conservation, are significant because they suggest the agency will be watching closely as states in the Northeast and Midwest embrace new drilling technologies to tap vast reserves of shale gas.

New York is in the forefront of the shale gas boom and has been working on regulations for more than three years. Judith Enck, the EPA regional administrator who issued the agency comments, noted that New York "will help set the pace for improved safeguards across the country."

The EPA's comments are among 20,000 the state has received on its proposed plan to regulate the environmental effects of drilling. Many of the EPA's comments focus on how the state DEC will handle the chemically tainted wastewater from the drilling process known as hydraulic fracturing, or fracking.

To free the gas trapped in the Marcellus and other shale formations, drillers pump millions of gallons of water mixed with sand and chemicals deep underground under pressure. The wastewater can get into drinking water by being disposed of at sewage treatment plants, the EPA wrote.

As ProPublica first reported in 2009, these plants don't typically have the equipment necessary to detect and treat the chemicals in drilling wastewater. Plant operators who accept drilling wastewater simply dilute it with regular sewage and then discharge it into water bodies. DEC wastewater samples had levels of radioactive elements thousands of times higher than drinking water limits, ProPublica reported.

In its comments, the EPA pointed out that New York's current permitting system for water treatment plants doesn't include limits on pollutants frequently contained in drilling wastewater, such as radionuclides, which can cause cancer at high levels.

Hydrofracking sparks earthquake concerns

ROCHESTER -- In early 2001, people living in northern Steuben County experienced something that many of them had never felt before -- a series of earthquakes, the largest of which was more powerful than any naturally occurring tremor in New York in a decade.

Damage was minimal but nerves were jangled. Because the epicenters were in an area not known to be quake-prone, officials looked for an explanation. They found one that might seem improbable.

The earthquakes were man-made, New York officials suspected -- the result of test injections of millions of gallons of water into two-mile-deep disposal wells built as part of a natural-gas storage operation being developed in the Town of Avoca.

State officials ordered a halt to the well tests. The elaborate gas storage facility was never finished and the site eventually abandoned.

The incident, which largely went unnoticed outside of Avoca and neighboring Cohocton, has been given fresh currency today because of the growing controversy in New York and nationwide over the natural gas drilling technique known as hydraulic fracturing.

The surge in hydrofracking has meant a surge in injection wells to dispose of drilling wastewater -- and those disposal wells are increasingly being linked to small earthquakes. Clusters of "induced" quakes in the Dallas-Forth Worth area and in Arkansas are prominent recent cases.

"There's a long list of examples," said Robert Ross, a geologist and associate director for the Paleontological Research Institution in Ithaca. "There's no question that small earthquakes can be induced."
