  • 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…

  • Determining frequency of coordination activities

    The Risk Management Program regulations require owners and operators of stationary sources to coordinate their response needs annually, or more frequently if necessary, with local emergency planning and response organizations (40 CFR §68.93(a)). Are stationary sources responsible for determining if coordination activities should occur more often than annually? Ultimate responsibility…

  • Who Must Develop an Emergency Response Program?

    The risk management program regulations require the owner or operator of a covered stationary source to develop and implement an emergency response program as described in 40 CFR §68.95, which must include an emergency response plan, emergency response equipment procedures, employee training, and procedures to ensure the program is up-to-date…

  • RMP*Comp and emergency response

    Can I use RMP*Comp for emergency response? No. It's a planning tool. Many other tools are available for response, including ALOHA . You can learn more by reading CAMEO tools for RMP .

  • Minimum and Maximum Distance to Endpoint

    The Chemical Accident Prevention Provisions require the completion of a worst-case release scenario analysis (40 CFR §68.25). This analysis includes estimating the greatest distance to endpoint as defined by the parameters in §68.22. Is there a required minimum or maximum distance for the distance to endpoint in the worst case…

  • Remote coordination with local authorities

    The Risk Management Program regulations require owners and operators of stationary sources to coordinate their response needs annually, or more frequently if necessary, with local emergency planning and response organizations (40 CFR §68.93(a)). If a stationary source is in a remote location and in-person annual coordination is deemed impractical, can…

  • Emergency Response Coordination Activities Effective Date

    The RMP Amendments finalized on January 13, 2017 included a requirement for owners or operators of a stationary source to engage in emergency response coordination activities (40 CFR §68.93). The regulatory text in 40 CFR §68.10(b) states that compliance with these activities must be completed by March 14, 2018. Because…

  • Are exercises required as a part of the emergency response program requirements under 40 CFR Part 68, Subpart E?

    Yes. At least once each calendar year, the owner or operator of a stationary source with any Program 2 or Program 3 process must conduct an exercise of the stationary source's emergency response notification mechanisms per 40 CFR 68.90(b)(3) or 68.95(a)(1)(i), as appropriate, before December 19, 2024, and annually thereafter…

  • Local meteorological data for alternative release scenarios

    For alternate release scenarios, RMP*Comp uses set values for meteorological conditions like humidity, wind speed, temperature, stability class, and so on. Is there a way to change those values? I want to use meteorology data from my own location. RMP*Comp indeed uses fixed values for certain atmospheric parameters, and does…

  • Different results using ALOHA and RMP*Comp

    I tried running the same scenarios in ALOHA and in RMP*Comp. I got different answers. Why? The results you obtain using RMP*Comp may not closely match the results you obtain running the same release scenario in a more sophisticated air dispersion model such as ALOHA or DEGADIS. That's because of…

  • Types of Information Relevant for Response Planning

    The Risk Management Program emergency response coordination activities require the owner and operator of a stationary source to provide to the local emergency planning and response organizations: the stationary source’s emergency response plan if one exists; emergency action plan; updated emergency contact information; and any other information that local emergency…
