Section 112(r)(7) of the CAA, 42 U.S.C. § 7412(r)(7), requires the Administrator to promulgate release prevention, detection, and correction requirements regarding regulated substances in order to prevent accidental releases. Respondent uses isobutane in a process at its Facility in amounts exceeding the threshold quantity. Respondent failed to comply with the requirements of 40 C.F.R. Part 68 violating Section 112(r)(7), 42 U.S.C. § 7412(r)(7). Respondent is therefore subject to the assessment of penalties under Section 113(d), 42 U.S.C. § 7413(d).
