Another Speedbump for U.S. EPA—Status of U.S. EPA RMP Stay May be at Risk

 
 
 
 
 

Methane

Likely emboldened by the U.S. Court of Appeals decision to vacate U.S. EPA's efforts to stay certain provisions of new source performance standards ("NSPS") relating to fugitive methane emissions, on July 24, 2017, a coalition of 11 Democratic state attorney generals filed a Petition for Review in the D.C. Circuit challenging U.S. EPA's June decision to delay implementation of the Obama administration's amendments to the Clean Air Act Risk Management Program ("RMP") for 20 months. This lawsuit is in addition to a previously filed lawsuit by environmental and labor groups that also challenged U.S. EPA's stay of the RMP amendments. 

In support of their petition, the AGs contend that the requirements of Section 307(d)(7)(B) of the CAA were not met which argument proved determinative in the earlier challenge to U.S EPA's stay of the  methane NSPS.  DOJ has already sought to distinguish U.S. EPA's delay of the methane NSPS from its delay of the RMP rule by noting that U.S. EPA sought public input on its proposed 20-month delay of the RMP rule in its March 30, 2017 federal register notice.  We will continue to track both of these lawsuits as they wind the D.C. Circuit.
