On February 22, 2021, the D.C. Circuit granted the Environmental Protection Agency’s (“EPA”) motion to stay the vacatur of the Trump administration’s Clean Power Plan Repeal Rule until EPA conducts further rulemaking on the issue in the case of American Lung Association v. EPA, No. 19-1140 (D.C. Cir., Feb. 22, 2021). This decision marks the latest action in the ongoing efforts by EPA and states to regulate greenhouse gas emissions; particularly in terms of carbon emissions from currently existing power plants. For additional background, please see previous MGKF blog on this topic here.  Read More »

On January 19, 2021, the U.S. Court of Appeals for the D.C. Circuit vacated and remanded the Trump administration’s Affordable Clean Energy Rule (“ACE Rule”), which itself was a rollback of the Obama administration’s Clean Power Plan (“CPP”); once again reshaping the heart of American climate policy. American Lung Association v. EPA, No. 19-1140 (D.C. Cir., Jan. 19, 2021). The CPP and ACE Rule both sought to regulate greenhouse gas (“GHG”) emissions from existing stationary sources but used highly divergent interpretations of the Clean Air Act (“CAA”) to do so. In making its ruling, the Court called the Trump Environmental Protection Agency’s interpretation of the CAA a “fundamental misconstruction” of the statute and provided a lengthy analysis of its findings. Id. at 16. The Court ultimately held that because the Environmental Protection Agency (“EPA”) based the ACE Rule “on an erroneous view of the law” (as opposed to having based the ACE Rule on a valid exercise of agency discretion), the court had no choice but to vacate the rule and remand it to the EPA for additional interpretation. Id. at 46. Because President Biden has described climate change as the “existential threat of our time,” the Biden EPA will likely use this opportunity to draft new rulemaking regarding the regulation of GHG emissions.

The D.C. Circuit recently held that EPA was not required to consider mitigation measures taken at a site when determining whether to add the site to the National Priorities List (“NPL”) under CERCLA. Meritor, Inc. v. EPA, No. 18-1325, 2020 WL 4299124 (D.C. Cir. July 28, 2020).

In 2016, the U.S. Environmental Protection Agency (“EPA”) conducted a study of indoor air quality at the Rockwell International Wheel & Trim facility (the “Site”), located in Mississippi, and discovered elevated concentrations of toluene, trichloroethylene (“TCE”), and cis-1,2-dichloroethene (“DCE”) in the main building at the Site. In 2017, Meritor, Inc. (“Meritor”), which inherited liability for contamination at the Site, conducted a subsurface investigation beneath the main building and uncovered elevated levels of toluene and TCE. In that same year, Meritor installed a sub-slab depressurization system designed to mitigate the impacts of vapor intrusion in the main building. In 2018, notwithstanding Meritor’s mitigation efforts, EPA added the Site to the NPL based on vapor intrusion impacts. Read More »

Last month, the D.C. Circuit, reversing a lower court decision, held that Guam was time-barred from pursuing its claims under CERCLA against the US Navy for the cleanup of the Ordot Dump on the island. Government of Guam v. United States of America, No. 1:17-cv-02487 (D.C. Cir. 2020). Of particular interest was the D.C. Circuit's determination that a 2004 Consent Decree entered into between EPA and Guam to resolve claims under a statutory scheme other than CERCLA, the Clean Water Act, nevertheless sufficiently “resolved” Guam’s liability for at least some remediation costs, giving rise to a contribution claim under Section 113 of CERCLA, bringing the D.C. Circuit in line with a majority of other federal appellate courts that have examined the issue. Read More »

The adage “you can’t put the toothpaste back in the tube” has manifested itself in two recent federal court decisions. Under separate theories, both the Second Circuit and the District Court of the District of Columbia have issued decisions that highlight the difficulty environmental groups faced in challenging energy infrastructure projects that have been completed during the course of litigation.

Last week, the U.S. Court of Appeals for the District of Columbia rejected all but one of the Environmental Defense Foundation’s (“EDF”) challenges to the U.S. Environmental Protection Agency’s (“EPA”) rulemaking implementing a statutory mandate to update the chemical substances inventory under the Toxic Substances Control Act, 15 U.S.C. §§ 2601-2692. See Envtl. Def. Fund. v. U.S. Envtl. Prot. Agency, No. 17-1201, 2019 WL 1867846 (D.C. Cir. Apr. 26, 2019). Read More »

In August 2016, pursuant to § 7601 of the Clean Air Act, EPA issued its proposed Amendments to Regional Consistency Regulations (“Amended Regulations”), 40 C.F.R. §§ 56.3-56.5 (2017). The Amended Regulations state that, for purposes of implementing the Clean Air Act nationwide, EPA would only apply decisions of the U.S. Supreme Court and U.S. Court of Appeals for the D.C. Circuit uniformly:

Only decisions of the U.S. Supreme Court and decisions of the U.S. Court of Appeals for the D.C. Circuit Court that arise from challenges to ‘nationally applicable regulations . . . or final action,’ as discussed in Clean Air Act section 307(b) (42 U.S.C. 7607(b)), shall apply uniformly.

In National Environmental Development Association’s Clean Air Project v. EPA, No. 16-1344 (D.C. Cir. June 8, 2016), industry groups (“Petitioners”) challenged the Amended Regulations in the D.C. Circuit on the basis that EPA is charged with implementing the Clean Air Act uniformly nationwide and must establish mechanisms for resolving judicially-created inconsistencies, as opposed to ignoring them. In the decision rendered earlier this month, the D.C. Circuit denied the petitions for review and upheld the Amended Regulations. Read More »

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 »

UPDATE: 

This past Thursday, the U.S. Court of Appeals for the District of Columbia Circuit delayed for two weeks its mandate which required the U.S. Environmental Protection Agency to lift its 90-day stay on portions of its methane rule for new oil and gas infrastructure.  The Court issued the mandate after determining that the EPA lacked authority under the Clean Air Act to issue the stay on the Obama-era regulations as further discussed in the original blog post below.  The order delaying the mandate indicates that the Court is providing EPA with time to “determine whether to seek panel rehearing, rehearing en banc, or pursue other relief” with respect to the mandate.  Thus, the methane rule is again on hold for the next several weeks while EPA decides whether and how to challenge the Court’s lifting of the 90-day stay.     

ORIGINAL POST:

Last week, the U.S. Court of Appeals for the District of Columbia Circuit struck down a 90-day stay imposed by the U.S. Environmental Protection Agency on portions of its methane rule for new oil and gas infrastructure, finding the agency lacked authority under the Clean Air Act to issue the stay. Clean Air Council v. Pruitt, No. 17-1145 (D.C. Cir. July 3, 2017).  The methane rule, which establishes “New Source Performance Standards” for fugitive emissions of methane and other pollutants by the oil and natural gas industries, was finalized in June 2016 by the Obama administration.  Notably, the Court’s 2-1 decision puts back into effect the June 3, 2017 deadline for regulated entities to conduct an initial monitoring survey to identify leaks from equipment.

In a unanimous decision penned by Circuit Judge Kavanaugh, the United States Court of Appeals for the D.C. Circuit affirmed a lower court decision holding that the EPA properly withheld information from its response to several environmental groups' Freedom of Information Act (“FOIA”) requests. Envtl. Integrity Project v. EPA, No. 16-5109, 2017 U.S. App. LEXIS 9332, at *4 (D.C. Cir. May 30, 2017).  The court held that Section 308 of the Clean Water Act (“CWA”) does not supersede Exemption 4 of FOIA. Id.  In relevant part, Section 308 of the CWA states that effluent data shall be made available to the public, unless releasing the information would divulge trade secrets.  33 U.S.C. § 1318(b) (1987).  Exemption 4 under FOIA, however, allows the government to withhold information that would reveal a company’s trade secrets or commercial or financial information.  5 U.S.C. § 552(b)(4) (2016).  Thus, the inconsistent exemptions have created tension in the lower courts that the D.C. Circuit has attempted to alleviate for future decisions in Environmental Integrity. Read More »
