Recent incidents raise issues on drilling, environment

Blanche Jefferson lives in Shreveport, but her worries are all south of here.
Her granddaughter and five great-grandchildren live south of Spring Ridge and close to where 17 cows died after ingesting liquid that spilled from a nearby natural gas drilling rig site into a pasture.
“I’m mostly concerned … stuff might get in the water,” said Jefferson, 79, adding that the family depends on well water.
The environmental impact of drilling has her so concerned that she’s rethinking whether she wants to lease mineral rights from property she owns in that area to an energy company in the future.
“Money is nothing if something happened to them,” she says of the children.
. . . . . Louisiana Department of Environmental Quality is reviewing several area incidents:
April: Seventeen cows died in a south Caddo Parish pasture after ingesting a liquid found pooled in the pasture, a spill from a nearby Chesapeake Energy drilling site. No reports on what killed the cows have been made public.
May: Fifteen Naborton families evacuated when a Chesapeake well east of Mansfield began blowing natural gas into the air. The air quality was monitored, and a Chesapeake spokesman said there was no threat to public safety or the environment. According to DEQ files on the case, 50 million standard cubic feet of methane gas — the main component of natural gas — was discharged after a casing valve failed.
DEQ doesn’t require notification of the release of 1 million standard cubic feet but does require notification of more than 2.5 million in a planned release. The Naborton release, however, was unplanned. Otis Randle, manager of the DEQ regional office here, said 50 million is “a lot of gas.” But he said people would not suffer health problems unless they breathed in a concentrated amount.
The main risk to nearby residents is the potential for explosion, and methane causes an adverse impact on the planet’s ozone layer, since methane is a greenhouse gas. The DEQ report on the Naborton well said the release did not have an off-site environmental impact. (un-naturalgas.org note: guess the atmosphere doesn’t count)
July: A natural gas well blowout occurred in north Sabine Parish, about six miles east of Converse. No residents were evacuated. The well was owned by Chesapeake, whose spokesman said there was no threat to the public or environment, and air quality was being monitored as a precaution. DEQ’s regional office in Shreveport investigated the blowout, finding it “pretty routine,” said Randle. No details on the amount released were available.
There are environmental concerns beyond reported incidents too:
Ground and surface water issues have arisen, particularly in south Caddo and DeSoto parishes, which heavily depend on the fragile Carrizo-Wilcox Aquifer. On the last day of June, about 1,000 customers of South DeSoto Water System had no water while workers replaced a pump. Officials wondered publicly if a natural gas drilling operation just 500 feet from their water well was making their equipment work harder to pump.
. . . . .
Many of the Web sites of the major competitors in the Haynesville Shale tout their dedication to preserving the environment.
Chesapeake’s page notes that it is a key contributor to The Nature Conservancy, and “our objective is to leave each site in as good, if not better, condition than when we started drilling.”
The U.S. Department of Interior recognized Devon Energy with a national award for its outstanding environmental and safety performance in the Gulf of Mexico.
And EnCana’s page notes: “We are looking at opportunities to recycle water and this option will become more viable as the play is further developed.”
While the proliferation of drilling in the Haynesville Shale is making environmental issues more visible and prominent, such concerns didn’t just arrive with the shale. Two cases from DEQ files:
In June, a Carthage, Texas, man pleaded guilty to a misdemeanor count of illegally discharging a pollutant into Louisiana waters after ordering a truck driver to discharge well treatment fluid into a Natchitoches Parish creek in April 2006. The man was sentenced to 24 months probation and agreed to pay a $5,000 criminal fine.
“Unfortunately, economic incentives drive environmental crime,” said Jeffrey T. Nolan, DEQ’s criminal investigations division manager.
In August 2006, DEQ responded to a landowner’s complaint that a well site where Winchester Energy was operating near Frierson had released at least four barrels of saltwater from a fracturing tank. According to DEQ files, the company had not contacted DEQ about the spill, which violates regulations. Also, the landowner said he asked Winchester to clean up the site but it refused. A few days later, DEQ noticed a cleanup in progress at the site, where vegetation had been killed in an area about 20 feet by 100 feet. DEQ in April this year deemed the site OK and did not take any action against Winchester.
