publishes an annual report, the latest of which is titled "2008 National Transportation Statistics." In that report, based on the number of incidents and train miles of travel, the frequency of an incident is 3 × 10−6 per train mile. Assuming 60 cars per train, obtainable from the AAR report titled "Train Facts," and based on statistics published by the FRA, there are 6 to 10 rail cars involved in a typical train incident.

The facility would fall under both OSHA and EPA regulations governing the handling of highly hazardous chemicals. One of the EPA requirements is that the facility's ERP estimates the consequences for their most limiting hazardous material incident, which is assumed here to be an explosion of a vessel containing ethylene.

To produce the vinyl chloride monomer, rail cars of chlorine are shipped to the facility. The facility has sufficient inventories of highly hazardous chemicals to fall under both the OSHA regulations for Process Safety Management of Highly Hazardous Chemicals (29 CFR 1910.119)

The Risk Management Plan developed to meet EPA regulations identified an ethylene oxide fire and explosion and chlorine release as the limiting accidents at the facility. The chlorine release was divided into a small release and a large release because of the different emergency response situations they present.
