A disagreement between groups of states is threatening to spill into a lawsuit over methane emissions regulations. Several northeastern states, including Connecticut, Delaware, Maryland, Massachusetts, New York, Rhode Island and Vermont, are threatening to sue the Environmental Protection Agency (EPA) under the Clean Air Act, trying to force the EPA to reconsider its decision not to impose regulations on methane emissions for oil and natural gas drilling, production and processing facilities.
In response to that threat, Oklahoma Attorney General E. Scott Pruitt wrote a letter to the EPA, joined by Alabama, Arizona, Indiana, Kansas, Montana, Nebraska, North Dakota, Ohio, South Dakota, Texas, West Virginia and Wyoming, calling on the EPA to resist this attempt to force a reconsideration of the methane emissions issue.
Attorney General Pruitt’s letter noted that the New Source Performance Standards (NSPS), pursuant to the Clean Air Act, may be reviewed and revised every eight years and that in the most recent review, the EPA did not chose to regulate the methane emissions at issue here. The EPA decided to review state standards instead. In their attempt to change the EPA’s decision, the northeastern states put forth several arguments, each of which the Attorney General countered in his well reasoned letter.
