The owner or operator of a stationary source covered by the risk management program regulations must conduct a worst-case release scenario analysis as part of the required hazard assessment (40 CFR §68.25). The worst-case release is defined as the release of the largest quantity of a regulated substance from a vessel or process line failure that results in the greatest distance to an endpoint (40 CFR §68.3).
If a release from the process containing the largest quantity of a regulated substance would result in a shorter distance to an endpoint than a release from a smaller process, which scenario should be considered the worst-case release?
