Administrative Watch
The U.S. Court of Appeals for the District of Columbia Circuit has vacated a USEPA memorandum aimed at limiting the reach of Summit Petroleum Corp. v. USEPA, (6th Cir. Aug 7, 2012), a case which condemned USEPA’s use of a functional interrelationship test in making single source determinations for air permitting. In Summit, the Sixth Circuit Court found that the regulatory term “adjacent” unambiguously relates only to physical proximity, and that USEPA’s contrary interpretation, which evaluated the functional interrelatedness of emission sources to determine whether they were adjacent, was inconsistent with both the plain meaning of the federal Clean Air Act (CAA) regulations and their history.
Following the Summit ruling, in December 2012, the USEPA Office of Air Quality Planning and Standards issued a memorandum (known as the “Summit Directive” or “Directive”) to all Regional Air Division Directors and Air Program Managers advising that, in the Sixth Circuit states of Michigan, Ohio, Tennessee and Kentucky, USEPA permitting officials “may no longer consider interrelatedness in determining adjacency when making source determination decisions.” With respect to regions of the country beyond the Sixth Circuit, however, the Summit Directive specified that agency officials would continue to consider functional interrelatedness in making source determinations.
A petition for review of the Summit Directive was filed shortly thereafter with the D.C. Circuit Court by a non-profit trade association representing resource extraction and manufacturing companies. The National Environmental Development Association’s Clean Air Project (NEDA/CAP) argued that the Directive violated CAA and regulatory provisions requiring national uniformity when administering CAA programs. NEDA/CAP also argued that the Directive resulted in a competitive disadvantage for member companies located outside of the Sixth Circuit, where USEPA would continue to rely on vague notions of functional interrelatedness to aggregate emission sources and thus require major source permitting. …
