6 D. Risk Analysis. 1. Likelihood of Release. a) This facility has experienced 2 releases that are useful for this analysis. b) Although neither of the releases involved an EHS, both situations demonstrated that the facility and jurisdictional emergency response organizations can deal with incidents at the facility in an appropriate and effective manner. c) The facility has been constructed with integral engineering safeguards and process controls for EHS. d) Quantities of EHS stored at the facility have been minimized to reduce off-site potentials. e) The United States Bureau of Labor Statistics for 1994 and 1995 show that this type of industry has the lowest incidence of injury. f) In the unlikely event of a release of an EHS, it is unlikely that the EHS would leave the site. 2. Severity of Consequences. Consequences might be severe if the worst case scenario were to occur at a time when the prevailing wind was blowing towards the critical facilities along Route 28 (Nokesville Road) at a time when the facilities were at maximum occupancy. 3. Risk Assessment. This facility is considered to be a moderate risk facility.
