On November 21, 2019, EPA released a pre-publication copy of its Reconsideration of the revised Risk Management Program (RMP) Rules. In an accompanying statement, the agency noted that it has taken steps to “modify and improve” the existing rule to remove burdensome, costly and unnecessary requirements while maintaining appropriate protection (against accidental chemical releases) and ensuring responders have access to all of the necessary safety information. This action was taken in response to EPA’s January 13, 2017 revisions that significantly expanded the chemical release prevention provisions the existing RMP rules in the wake of the disastrous chemical plant explosion in West, Texas. The Reconsideration will take effect upon its publication in the Federal Register.
As recounted by the D. C. Circuit in its August 2018 decision in the case of Air Alliance Houston, et al. v. EPA, in 1990, the Congress amended the Clean Air Act to force the regulation of hazardous air pollutants (see 42 USC Section 7412). An initial list of these hazardous air pollutants was also published, at Section 7412 (b). Section 112(r) (codified at 42 USC Section 7412 (r)), authorized EPA to develop a regulatory program to prevent or minimize the consequences of a release of a listed chemical from a covered stationary source. EPA was directed to propose and promulgate release prevention, detection, and correction requirements applicable to stationary sources (such as plants) that store or manage these regulated substances in amounts determined to be above regulated threshold quantities. EPA promulgated these rules in 1996 (see 61 FR 31668). The rules, located at 40 CFR Part 68, contain several separate subparts devoted to hazard assessments, prevention programs, emergency response, accidental release prevention, the development and registration of a Risk Management Plan, and making certain information regarding the release publicly available. EPA notes that over 12.000 RMP plans have been filed with the agency.
In January 2017, in response to the catastrophe in West, EPA issued substantial amendments to these rules, covering accident prevention (expanding post-accident investigations, more rigorous safety audits, and enhanced safety training), revised emergency response requirements, and enhanced public information disclosure requirements. (See 82 FR 4594 (January 13, 2017).) However, the new administration at EPA, following the submission of several petitions for reconsideration of these revised rules, issued a “Delay Rule” on June 14, 2017, which would have extended the effective date of the January 2107 rules until February 19, 2019. On August 17, 2018, the Delay Rule was rejected and vacated by the D.C. Circuit in the aforementioned Air Alliance case (see 906 F. 3d 1049 (DC Circuit 2018)), which had the effect of making the hotly contested January 2017 RMP revisions immediately effective.
