  • Why are industries exempt under OSHA's PSM subject to RMP?

    The Program 3 prevention program requirements under 40 CFR Part 68 are almost identical to the requirements of OSHA's process safety management (PSM) standard. OSHA exempts certain industries from the PSM standard. Why does EPA not exempt those same industries from the CAA §112(r) risk management program requirements? EPA and…

  • Redoing calculations if RMP*Comp is updated

    Will RMP*Comp be updated? If so, would I have to redo calculations I might already have made with an earlier version? No, you do not have to redo your work if you have already completed your consequence analyses. RMP*Comp is based on the EPA's Offsite Consequence Analysis Guidance (OCA Guidance)…

  • Different distances to toxic endpoints with different versions of RMP*Comp

    I've noticed that for certain chemicals, RMP*Comp gives substantially different distances to the toxic endpoint than previous versions. Why? In the current version of RMP*Comp, we have incorporated new chemical-specific distance tables for ammonia, chlorine, and sulfur dioxide. The generic tables are still used for other chemicals (you can see…

  • Distance to endpoint calculations used by RMP*Comp

    Does RMP*Comp perform some math or modelling in order to arrive at an endpoint distance, or is it simply interpolating from the tables in the EPA's Offsite Consequence Analysis Guidance (OCA Guidance)? RMP*Comp follows the procedures set out in the OCA Guidance . This means that for some scenarios, the…

  • What if the quantity in the process fluctuates?

    What if the quantity in the process fluctuates? I may not have a threshold quantity now, but I will intermittently exceed the threshold quantity. You do not need to comply with the rule and file an RMP unless you have more than threshold quantity in a process; however, once you…

  • Process identification and distance between vessels

    How far apart do separate vessels have to be to be considered different processes? There is no hard and fast rule for how great this distance should be before you do not need to consider the vessels as part of one process. Two vessels at opposite ends of a large…

  • What does "same industrial group" mean?

    Operations at a site that belong to the same three-digit North American Industry Classification System (NAICS) code prefix (which has replaced the old SIC codes) belong to the “same industrial group. In addition, where one or more operations at the site serve primarily as support facilities for the main operation…

    What if EPA lists a new substance? You will have three years from the date on which the new listing is effective to come into compliance for any process that is covered because EPA has listed a new substance.

  • Should tank capacity be considered when determining thresholds?

    When determining whether a threshold amount of a regulated substance is present in a process (e.g., a tank), must the owner or operator of a stationary source consider the total capacity of the process, or the actual amount of regulated substance contained in the process? The threshold determination is based…

  • Does the chlorine listing apply only to gaseous forms of chlorine?

    There is no qualifier attached to the listing for chlorine (40 CFR §68.130). The listing, therefore, applies to chlorine (CAS number 7782-50-5), regardless of physical state.

  • If laboratory chemicals are stored outside the laboratory, are they exempt from threshold determination?

    Under 40 CFR Part 68, for the purpose of determining whether more than a threshold amount of a regulated substance is present at a stationary source, certain exemptions may apply. One such exemption is provided for "activities in laboratories" (40 CFR §68.115(b)(6)). If laboratory chemicals are stored outside the laboratory…

  • Calculating thresholds for toxic substances with concentration qualifiers

    Several toxic substances are listed as regulated substances under 40 CFR §68.130 with concentration qualifiers (e.g., "conc 37% or greater"). What does this concentration mean? When determining whether a threshold amount of these substances exists in a process, should I consider the weight of the entire solution, or simply the…
