Does EPA interpret the Program 3 process hazard analysis - stationary source siting requirement analogously to OSHA's Process Safety Management standard?
Yes. The requirement to consider stationary source siting during the process hazard analysis means that you should consider the location of the covered vessels and evaluate whether their location creates risks for offsite public or environmental receptors, as well as onsite receptors. This analysis should consider the proximity of the vessels that could lead to a release of a regulated substance. The proximity of the vessels to onsite equipment or activities nearby will have been considered for OSHA; the proximity of the vessels in relation to offsite receptors will be considered if not already considered for OSHA. The analysis may be done qualitatively. The analysis addresses whether the location of the vessels creates risks that could be reduced by changing the location or taking other actions, such as installing mitigation systems. The evaluation of offsite consequences is more fully addressed under the hazard assessment requirement.
