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 »

Last week, the United States District Court for the Western District of Washington, in Trident Seafoods Corp. v. Bryson, No. C12-134 MJP (Nov. 30, 2012), sent litigants a reminder about the necessity of proper standing in rulemaking challenges.  Indeed, standing is often one of the most difficult aspects of these cases, and often result in early case dismissal, as it did in Trident.

Last Friday, the U.S. Court of Appeals for the District of Columbia Circuit published two decisions in cases involving environmental groups’ challenges to EPA’s efforts to regulate certain classes of hazardous air pollutants (“HAPs”).  Both cases concerned Section 112(c)(6) of the Clean Air Act, a provision enacted by Congress in 1990 that requires EPA to (1) complete a list of sources of seven specified HAPs that accounts for at least ninety percent of the total emissions of each of the seven HAPs and (2) subject these listed sources to emissions standards.  42 U.S.C. § 7412(c)(6).  Section 112(c)(6) gives EPA a choice among two emission standards:  (1) a stringent standard known as “maximum achievable control technology” (“MACT”) or (2) a standard based on health thresholds.  See § 112(c)(6), (d)(2) and (d)(4).  The cases decided last Friday highlight both procedural and substantive aspects of regulating air pollution.

On Monday, the United States District Court for the District of Columbia issued an opinion in Sierra Club v. Jackson, No. 11-1278 (D.C.D.C. Jan. 9, 2012), that has much to chew on with respect to judicial review of agency actions, particular those involving stays.  For those not following this long-running saga, a brief background is in order.
