  • 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…

  • 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…

  • Is there anything I can do to make surfaces resistant to SARS-CoV-2 (COVID-19)?

    List N: Disinfectants for Use Against SARS-CoV-2 View List N, a searchable and sortable list of products for use against SARS-CoV-2, the novel human coronavirus that causes COVID-19. EPA regulates the claims on pesticide product labels. EPA-registered surface disinfectants kill viruses at the time they are used. After use, if…

  • Can I use common household substances to kill the novel coronavirus?

    List N: Disinfectants for Use Against SARS-CoV-2 View List N, a searchable and sortable list of products for use against SARS-CoV-2, the novel human coronavirus that causes COVID-19. EPA does not review effectiveness of common household ingredients like vinegar or rubbing alcohol, so EPA cannot verify how well they work…

  • 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…
