EXECUTIVE SUMMARY WTP Executive Summary City of Jackson ACCIDENTAL RELEASE PREVENTION AND EMERGENCY RESPONSE POLICIES At the City of Jackson Water Treatment Plant we are committed to operating and maintaining our process using hazardous substance in a safe and responsible manner. We use a combination of accidental release prevention programs and emergency response planning programs to help ensure the safety of our employees and the public as well as protection of the environment. This document provides a brief overview of the comprehensive risk management activities that we have designed and implemented, including: * A description of our facility and use of substances regulated by EPA's RMP regulation * A summary of results from our assessment of the potential offsite consequences from accidental chemical releases * An overview of our accidental release prevention programs * A five-year accident histo ry for accidental releases of chemicals regulated by EPA's RMP rule * An overview of our emergency response program * An overview of planned improvements at the facility to help prevent accidental chemical releases from occurring and adversely affecting our employees, the public, and the environment * The certifications that EPA's RMP rule requires us to provide * The detailed information (called data elements) about our risk management program STATIONARY SOURCE AND REGULATED SUBSTANCES Our facility treats drinking water using a variety of chemicals in the process. We have a 24 Million Gallon Per Day Split Treatment Softening Plant which treats drinking water for the City of Jackson and surrounding communities. In our processes, we use the following chemicals that EPA has identified as having the potential to cause significant offsite consequences in the event of a substantial accidental release: Toxics We use Chlorine for disinfection of potable water. We have 6 one ton ta nks of chlorine on site. We use two of those at one time hooked to a chlorine gas manifold and the other 4 one ton tanks are for replacing the 2 when they are empty. Our accidental release prevention programs and our contingency planning efforts help us effectively manage the hazards that are posed to our employees, the public, and the environment by our use of these chemicals. KEY OFFSITE CONSEQUENCE ANALYSIS SCENARIOS EPA's RMP rule requires that we provide information about the worst-case release scenario and alternative release scenario for our facility. The following are brief summaries of these scenarios, including information about the key administrative controls and mitigation measures to limit the exposure distances for each scenario: Worst-case Release Scenario - Regulated Toxic Chemicals We have two one ton tanks of chlorine hooked to a chlorine gas manifold and this chlorine gas manifold ruptures, and there is a bad leak, this a Worse-Case Scenario under stipulate d weather conditions there is a estimated exposure distance of 4.7 miles, 10-minute release at 220 lbs./min. the chlorine feed system and ton tanks are located in a enclosed room. Within this 4.7 miles we have Residences, School, Hospitals, Prison, Public Recreational Areas, and Major Commercial, Office, or Industrial Areas. We have Process Safety Management and Emergency Response Programs in effect. Alternative Release Scenario Have two one ton chlorine tanks connected to a chlorine gas manifold with a stainless steel pig tail and the connections are made using gaskets, and one of those gaskets are leaking, this is a altenative process scenario under stipulated weather conditions there is estimated exposure distance oh 1.1 miles, 10 minute release at 110 lbs./min. the chlorine feed system and ton tanks are located in a enclosed room. Within this 1.1 miles we have Residences and Major Commercial, Office, or Industrial areas. We have Process Safety Management and Emergency Response Programs in effect. We are using this information to help us ensure that our emergency response plan and the community emergency response plan address all reasonable contingency cases. GENERAL ACCIDENTAL RELEASE PREVENTION PROGRAM AND CHEMICAL-SPECIFIC PREVENTION STEPS We take a systematic, proactive approach to preventing accidental releases of hazardous chemicals. Our management systems ad dress each of the key features of successful prevention programs including: * Process safety information * Process hazard analysis * Operating procedures * Training * Mechanical integrity * Management of change * Pre-startup review * Compliance audits * Incident investigation * Employee participation * Hot work permit * Contractors As part of our prevention efforts, we have implemented the following chemical-specific prevention steps: Preventative Maintenance with Daily, Weekly,and Monthly maintenance tasks and inspections. Employee Training with class room training, written test and on the job training. Written instructions for operation and maintenace of the chlorine system. We are in compliance with the Process Safety Management Rule. Chlorine Ton tank valve actuators that shut the valves on the chlorine ton tanks when the alarm from the chlorine detector alarms or the process operator pushes button to actuate the valves. We are also in the process of ins talling a scrubber system. These individual elements of our prevention program work together to prevent accidental chemical releases. Our company and our employees are committed to the standard that these management systems set for the way we do business, and we have specific accountabilities and controls to ensure that we are meeting our own high standards for accident prevention. FIVE-YEAR ACCIDENT HISTORY We have not had any significant accidental chemical releases that occurred at our facility. If in the future we have any accidental chemical releases we will have records of it. We will also conduct formal incident investigations to identify and correct the root cause of the events. EMERGENCY RESPONSE PROGRAM We maintain an integrated contingency plan, which consolidates all of the various federal, state, and local regulatory requirements for emergency response planning. Our program provides the essential planning and training for effectively protecting workers, the public, and the environment during emergency situations. Furthermore, we coordinate our plan with the community emergency response plan. PLANNED CHANGES TO IMPROVE SAFETY The following is a list of improvements that we are planning to implement at the facility to help prevent and/or better respond to accidental chemical releases: We are having a Scrubber System installed to scrub the air if a chlorine leak happens. CERTIFICATIONS For all other covered processes, the undersigned also certifies that, to the best of my knowledge, information, and belief, formed after reasonable inquiry, the other information submitted in this RMPlan is true, accurate, and complete.
