This Administrative Consent Order (ACO) for ANR Pipeline Company (ANR) with operations at ANR's Sandwich Compressor Station in Sandwich, Illinois, addresses violations regarding the New Source Performance Standards for Crude Oil and Natural Gas Facilities for which Construction, Modification or Reconstruction Commenced After September 18, 2015, found at 40 C.F.R. Part 60, Subpart OOOOa.
ANR failed to repair a leak of a fugitive emissions component at its Sandwich Compressor Station within the 2-year timeframe required by 40 C.F.R. ? 60.5397a(h)(3), and notified EPA in a letter submitted one month before the 2-year repair deadline requesting an extension.
EPA noted that there is no mechanism in NSPS Subpart OOOOa or the NSPS general provisions for granting an extension of the 2-year repair deadline in 40 C.F.R. ? 60.5397a(h)(3), and because ANR had not repaired the leaks within the required timeframe, it was in violation of 40 C.F.R. ? 60.5397a(h)(3). EPA acknowledged that between September 2020 and June 30, 2021, the transmission and storage sector (of which ANR's Sandwich Compressor Station operations are a part) was not subject to the requirements of NSPS Subpart OOOOa due to the promulgation of a revised NSPS OOOOa rule. However, the subsequent repeal of that revised NSPS OOOOa rule via the Congressional Review Act and signature by the President in June 2021 reinstated the original NSPS OOOOa rule to which ANR's Sandwich Compressor Station operations were subject.
