Anyone who has submitted an RMP or maybe done a Worst Case Scenario (WCS) using EPA’s modeling software “RMP* Comp” will recognize this little checkbox at the bottom of the data page just above the SUBMIT button…
But when is this little checkbox, which can have a large impact on your scenario, allowed to be checked? When should it be checked to be technically accurate? I wish there was a way I could search the RMP database of those submittals that used RMP*Comp to see how many plans claimed this PASSIVE mitigation measure in their WCS; but since that is not possible I was wondering how many of you, in your RMP WCS, have claimed the WCS occurred in “enclosed space, in direct contact with outside air” when using RMP* Comp?
