General Executive Summary for LaRoche Industries Inc. LaMirada, CA Distribution Center 1. Accidental Release Prevention and Emergency Response Policies We at LaRoche Industries, 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 Distribution of Anhydrous Ammonia and Aqueous Ammonia to customers via trailers, DOT skid tanks, and cylinders. We have 2 regulated substances present at our facility. These substances include Ammonia (anhydrous) and Ammonia (aqueous) both of which are sold to customers. The maximum i nventory of Ammonia (anhydrous) at our facility is 778795.00 lb. while Ammonia (aqueous >20%) is present at our facility in a maximum quantity of 65161.57 lb. 3. The Worst Case Release Scenario(s) and the Alternative Release Scenario(s), include 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. 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 Anhydrous Ammonia Storage . In this scenario 160000 lb. of Ammonia (anhydrous) 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. At Class F atmospheric stability and 1.5 m/s windspeed, the maximum distance of 5.6 miles is obtained corresponding to a toxic endpoint of 0.14 mg/L. The alternative release scenario for Ammonia (anhydrous) involves a release from Anhydrous Ammonia Storage . The scenario involves the release of 2380.22 lb. of anhydrous ammonia. 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 excess flow valve(s), deluge system(s) and emergency shutdown system(s). Under neutral weather conditions, the maximum distance to the toxic endpoint of 0.14 mg/L of Ammonia (anhydrous) is 0.31 miles. The alternative release scenario for Ammonia (conc 20% or greater) involves a release from Aqueous Ammonia Storage. The scenario involves the release of 3299 lb. of aqueous ammonia. 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. Passive mitigation controls such as dike(s) are taken into account to calculate the scenario. The release is also assumed to be controlled by excess flow valve(s), deluge system(s) and emergency shutdown system(s). Under neutral weather conditions, the maximum distance to the toxic endpoint of 0.14 mg/L of Ammonia (conc 20% or greater) is 0.31 miles. 4. The General Accidental Release Prevention Program and the Chemical-Specific Prevention Steps Our facility has taken all the necessary steps to comply with the accidental release prevention requirements set out under 40 CFR part 68 of the EPA. The following sections briefly describe the elements of the release prevention program that is in place at our stationary source.
