UPDATED 9/26/22
Pursuant to the Risk Management Program regulations, the owner or operator shall identify and analyze at least one alternative release scenario for each regulated toxic substance held in a Program 2 or Program 3 process above its threshold (40 CFR §68.28). If a facility has both ammonia and ammonia (anhydrous) on-site above their respective thresholds, does the facility owner or operator need to complete an alternative release scenario for both ammonia and ammonia (anhydrous), or can they complete just one?
