Executive Summary 1. Accidental release prevention and Emergency Response policies We at Caqon City Water Treatment Plant are 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. Unforeseeably, if such a release does occur, our highly trained emergency response personnel are at hand to control and mitigate the effects of the release. We are also completely coordinated with Caqon City Fire Protection District which provides additional emergency response expertise. 2. The Stationary Source and the Regulated Substances Handled We have 1 regulated substance present at our facility which is Chlorine. The maximum inventory of C hlorine at our facility is 6000 lbs. 3. The Worst Case Release Scenario and the Alternative Release Scenario, 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 look-up tables and equations provided by the EPA in the RMP Offsite Consequence Analysis Guidance. The following paragraphs provide details of the chosen scenarios. Toxic Worst-case analyses The Worst Case scenario involves a catastrophic release from Disinfection. The scenario involves the release of 2000 lb. of Chlorine in a gaseous form over 10 minutes. The Release rate (lbs/min) is calculated to be 200. A distance to endpoint of 5.4 miles is obtained which affects a residential population of 26577 within this distance. Toxic Alternative-case analyses The Alternative Case scenario involves a catastrophic release from Disinfection. The scenario involves the rele ase of 0.6 lb. of Chlorine in a gaseous form. Active mitigation controls such as sprinkler and scrubbers are also taken into account to calculate the scenario. The Release rate (lbs/min) is calculated to be 0.3 and a Distance to endpoint of 0.1 miles is obtained which affects a residential population of 2. Flammables Worst-case analyses None applicable Flammables Alternative-case analyses None applicable 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.
