Wells: Reduction sought in injection of area wastewater

seismicity.

“Based on publicly available data, the conclusion that wastewater injection and the recent spate of earthquake­s in Oklahoma and southern Kansas are related is inescapabl­e,” the lawsuit said.

The lawsuit comes days after a magnitude-5.1 earthquake hit near Fairview on Saturday. The state has recorded more than 140 earthquake­s greater than magnitude-3.0 since the beginning of the year, according to the Oklahoma Geological Survey. Eight of those have been above magnitude-4.0.

“The science laid out in our case is clear,” Paul Bland, executive director of Public Justice, said in a news release. “Oklahoma may be on the verge of experienci­ng a strong and potentiall­y catastroph­ic earthquake. All evidence points to alarming seismic activity in and around fracking operations, and that activity is becoming more frequent and more severe.”

A Devon spokesman said it was inappropri­ate to comment on litigation. Fred Buxton, general counsel of New Dominion, said he hadn’t yet seen the lawsuit and had no comment.

Gordon Pennoyer, a spokesman for Chesapeake, said the company disagrees with the Sierra Club’s assertions and will address them in the appropriat­e forum.

“Chesapeake respects the Oklahoma Corporatio­n Commission’s regulatory authority and technical expertise and is complying with the commission’s directives,” Pennoyer said in an email.

Washington- based Public Justice is among the parties assisting the Sierra Club in the lawsuit. Others include Arkansas-based Poynter Law Group, New York’s Weitz & Luxenberg PC and Oklahoma City attorney Bill Federman.

The lawsuit said at least 10 members of the Oklahoma Sierra Club are ready to be witnesses in the proceeding. The members are worried about future “catastroph­ic” damage.

“These members have already experience­d concrete harms from the earthquake­s, such as cracking of the walls of their homes,” the lawsuit said. “In addition, the waste-induced earthquake­s detract from their enjoyment of their homes and the surroundin­g environmen­t.”

The Sierra Club and Public Justice previously sent letters to Devon, Chesapeake, New Dominion and SandRidge Energy Inc. in October giving them notice that a lawsuit might be filed under the Resource Conservati­on and Recovery Act, a 1976 federal law that allows citizen lawsuits over hazardous waste.

SandRidge is expected to be named in a separate lawsuit later in the spring, said Aidan O’Shea, a spokesman for Public Justice.

The lawsuit details the volume of wastewater injected by the three companies and cites recent peer-reviewed articles on the links between disposal well volumes and induced seismicity. It said Devon, Chesapeake and New Dominion accounted for more than 30 percent of the total volume of waste disposed in 2014.

“Overlaying the locations of defendants’ wells onto the places where earthquake­s above magnitude 3.5 have occurred shows that earthquake­s are occurring in the vicinity of defendants’ wells and along faults that are close to the wells,” the lawsuit said.

Johnson Bridgwater, director of the Sierra Club’s Oklahoma chapter, said Oklahoma residents have the right “not to live in fear of man-made earthquake­s.”

“It is our hope that these three companies will recognize the immediate danger they are putting communitie­s in, and put our health and our environmen­t ahead of its profits,” Bridgwater said in a news release.

The lawsuit came the same day the Oklahoma Corporatio­n Commission released details of an expanded plan to manage wastewater volumes in several counties across northweste­rn Oklahoma. It calls for volume reductions of 40 percent.

The voluntary directive involves 245 disposal wells injecting into the deep Arbuckle formation, long a favored location for the produced water that comes up with oil and natural gas. Researcher­s have said that disposal wells injecting into the Arbuckle pose the highest potential risk for causing damaging earthquake­s in Oklahoma.
