DC Circuit Court of Appeals Vacates Ace Rule

On January 19, 2021, the D.C. Circuit Court of Appeals vacated the Affordable Clean Energy (ACE) Rule. The Court concluded, “Because promulgation of the ACE Rule and its embedded repeal of the Clean Power Plan rested critically on a mistaken reading of the Clean Air Act, we vacate the Ace Rule and remand to the Agency. We also vacate the amendments to the implementing regulations that extend the compliance timeline.” A copy of the Court’s decision is available here.

UPDATE: On February 12, 2021, EPA issued a memorandum to all EPA Regional Administrators to clarify that states do not have any obligations under the ACE Rule or the previous Clean Power Plan.  A copy of the EPA memorandum is available here.

EPA Seal

On October 1, 2020, the EPA Administrator signed final revisions to 40 CFR Part 63, National Emission Standards for Hazardous Air Pollutants for Source Categories.

The rule will become effective sixty (60) days after publication in the Federal Register.  The rule is designed to formalize EPA’s 2018 guidance memorandum which overturned EPA previous policy of “once in, always in” (OIAI), which is often referred to as the May 1995 Seitz Memorandum.

The rule also finalizes revisions to the Part 63 General Provisions clarifying “that a major source can be reclassified to area source status at any time upon reducing its potential to emit (PTE) hazardous air pollutants (HAP) to below the major source thresholds (MST) of 10 tons per year (tpy) of any single HAP and 25 tpy of any combination of HAP.”

Additionally, the final rule specifies compliance dates, notification, and recordkeeping provisions applicable to sources electing to reclassify to area source status or to sources reverting back to major source status.  A copy of the prepublication version of the rule is available here.

EPA has now stated that each fuel flowmeter must meet the minimum data capture requirement for continuous monitoring systems in 75.10(d)(1), the same requirement for CEMS.Read more »
