Section 612 of the Clean Air Act (“CAA”) requires that manufacturers replace substances that have been determined to deplete the stratospheric ozone layer with alternatives that do not have the same effect. Section 612 further directs EPA to develop a list of safe substitutes and a list of prohibited substitutes. Hydrofluorocarbons (“HFCs”) were on the safe substitutes list until 2015, when EPA moved many of them to the prohibited substitutes list.  EPA asserted that this change required manufacturers who had been using HFCs to replace them with other substances from the safe list.  The 2015 Rule was challenged, and on August 8, 2017, in Mexichem Fluor Inc. et al., v. U.S. Environmental Protection Agency, No. 15-1328, the D.C. Circuit vacated the 2015 Rule to the extent that it required manufacturers to cease using HFCs as a replacement for ozone-depleting substances.  Read More »

Yesterday, the Pennsylvania Environmental Hearing Board issued an important decision that provides guidance on how to apply Article I, Section 27 of the Pennsylvania Constitution (“Environmental Rights Amendment” or “ERA”) in the context of a permitting decision in light of the Pa. Supreme Court’s recent decision in Pa. Environmental Defense Found. v. Commonwealth, No. 10 MAP 2015 (Pa. June 20, 2017) (“PEDF”).  See Center for Coalfield Justice v. DEP, EHB Docket No. 2014-072-B (Adjudication issued Aug. 15, 2017).   Read More »

Is a leaking pipeline indicative of an operator’s failed attempt to consider all relevant risk factors when the pipeline has had leaks in the past? In the context of pipeline integrity management regulations, the Court of Appeals of the Fifth Circuit said no.  On August 14, 2017, the Court vacated, in part, a final order issued by the Pipeline Hazardous Materials Safety Administration (“PHMSA”) to ExxonMobil Pipeline Company (“ExxonMobil”), which found that ExxonMobil failed to properly consider the susceptibility of certain portions of its Pegasus Pipeline to seam failure and assessed a civil penalty of $2.6 million.  The opinion in ExxonMobil Pipeline Company v. United States DOT determined that, despite an oil leak from its Pegasus Pipeline, ExxonMobil was not in violation of PHMSA regulations requiring it to consider all risk factors that reflected the risk conditions on a certain pipeline segment because ExxonMobil “carefully [underwent] an informed decision-making process in good faith, reasonably taking into account all relevant risk factors in reaching a decision” that the pipeline was not at risk of seam failure.  2017 U.S. App. LEXIS 15144 (Aug. 14, 2017).

On July 19, 2017, the Tenth Circuit Court of Appeals held that the United States, as the title owner of a former mine, was a Potentially Responsible Party (PRP) under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), despite the fact that it did not have a possessory interest in the property at the time of the disposal of hazardous substances.  The opinion in Chevron Mining Inc. v. United States, No. 15-2209, 2017 U.S. App. LEXIS 12959, at *1 (10th Cir. July 19, 2017) thus appears to put to rest a defense often asserted, primarily by governmental entities, that “bare legal title” is insufficient for CERCLA liability to attach and instead that some other and additional “indicia of ownership” is required.
