Southchem Inc. Durham, NC., Executive Summary Southchem is a member of National Association of Chemical Distributors and complies with the requirements of the Responsible Distribution Process. 1. Accidental Release Prevention and Emergency Response Policies We at Southchem Inc are strongly committed to employee, public and environmental safety. This commitment is demonstrated by our comprehensive accidental release prevention program that covers areas such as design, installation, operating procedures, maintenance, and employee training associated with the processes at our facility. It is our policy to implement appropriate controls to prevent possible releases of regulated substances. 2. The Stationary Source and the Regulated Substances Handled Our facility's primary activities encompass Chemical distribution. We have 5 regulated substances present at our facility. These substances include Ammonia (aqueous), Chlorine, Formaldehyde (solution), Hydrogen fluoride/Hydrofluoric acid [Hydrofluoric acid] and Sulfur dioxide (anhydrous). Ammonia (aqueous), Chlorine, Formaldehyde (solution), Hydrogen fluoride/Hydrofluoric acid [Hydrofluoric acid] and,Sulfur dioxide (anhydrous) are repackaged stored and distributed. 3. The Worst Case Release Scenario(s) and the Alternative Release Scenario(s), including administrative controls and mitigation measures to limit the distances for each reported scenario To perform the required offsite consequence analysis for our facility, we have used the EPA's OCA Guidance Reference Tables or Equations and the EPA's RMP*Comp(TM). The following paragraphs provide details of the chosen scenarios. The worst case release scenario submitted for Program 2 and 3 toxic substances as a class involves a catastrophic release from Formaldehyde. In this scenario 3000 lb. of Formaldehyde (solution) is released. The toxic liquid released is assumed to form a 1 cm deep pool from which evaporation takes place. The entire pool is estimated to evaporate over 10 minutes. Passive mitigation systems such as dike(s) are also taken into account to calculate the scenario. At Class F atmospheric stability and 1.5 m/s windspeed, the maximum distance of 3 miles is obtained corresponding to a toxic endpoint of 0.012 mg/L. The alternative release scenario for Formaldehyde (solution) involves a release from Formaldehyde. The scenario involves the release of 185 lb. of . Toxic liquid is assumed to be released to form a 1 cm deep pool from which evaporation takes place. The entire pool is estimated to have evaporated after 10 minutes. The release is also assumed to be controlled by neutralization. Under neutral weather conditions, the maximum distance to the toxic endpoint of 0.012 mg/L of Formaldehyde (solution) is 0.56 miles. The alternative release scenario for Chlorine involves a release from Chlorine storage. The scenario involves the release of 150 lb. of . Toxic liquid is assumed to be released to form a 1 cm deep pool fro m which evaporation takes place. The entire pool is estimated to have evaporated after 1 minutes. Under neutral weather condit |
