2.1 IDENTIFYING CANDIDATE REFINING OPERATIONS SUBJECT TO RMP RULE COVERAGE Refining operations begin at the feed storage tanks or pipelines on the refinery property. Some of these facilities and operations may be exempt from the RMP rule because of two types of exemptions: (1) exemptions from consideration as a stationary source covered under the RMP rule and (2) exemptions from considering regulated flammable substances in TQ calculations. Operations at a refinery involving regulated flammable substances in naturally occurring hydrocarbon streams prior to processing in refining units are exempt from the RMP rule (e.g., crude oil and condensate storage tanks). Note: Transportation and storage incident to transportation are not covered by the RMP rule. However, DOT is presently undertaking rulemaking to clarify what activities it considers to be “in the transportation process.” 2.2 IDENTIFYING REGULATED SUBSTANCES IN REFINING PROCESSES Once candidate refining operations that comprise the stationary source are determined, the next step is to identify regulated substances in the refining processes. Refineries operate a variety of processes involving flammables and some regulated toxic substances. The refinery should develop a list of regulated substances used in each process area and determine a rough estimate of the inventory of the substance in the process. If the refinery documented its technical basis for coverage under OSHA’s PSM regulation, this information may already exist. Then, the refinery should examine the regulated substances it has and compare the process inventory estimates to the EPA TQs. Table 2-1 contains examples of common refining processes and support systems and the types of regulated substances that may be present.
Based on the information regarding which regulated substances exist in refining processes at stationary sources, the next step is to estimate the process inventory for each regulated substance. In most cases, refineries may use the definition for processes that they used in determining coverage under OSHA’s PSM regulation as a starting point. Note: EPA and OSHA both interpret the definition of process to mean that separate vessels that are not interconnected and that are located sufficiently far from each other and other covered processes, such that a failure in one vessel is unlikely to affect the other(s), may be treated as separate processes. In the preamble to the RMP rule, EPA clearly stated its intent to be consistent with OSHA’s interpretation of “process” as that term is used in OSHA’s PSM rule. Therefore, if your facility is subject to the PSM rule, the limits of your process(es) for purposes of OSHA PSM will be the limits of your process(es) for purposes of RMP (except in cases involving atmospheric storage tanks that contain flammable regulated substances, which are exempt from PSM but not RMP). Note: Determining interconnection of vessels is not necessarily straightforward and will often depend on site- specific factors. The rule is driven by a concern for the potential to release at least a threshold quantity of a regulated substance. For a large refinery or multiunit chemical plant, determining whether an interconnection exists and defining the boundaries of a process will require engineering judgment. For example, if vessels containing regulated substances are connected by only utility lines (e.g., piping carrying cooling water), you will have to determine whether the vessels could be involved in a single release.
The RMP rule requires that the maximum intended inventory of each regulated toxic material, flammable material, or flammable mixture in each RMP-covered process be reported in the RMPlan. Table 2-2 summarizes the process inventory information that must be included in the registration section of the RMPlan for each RMP-covered process.
