RISK MANAGEMENT PLAN FOR THE CITY OF WINFIELD WATER TREATMENT PLANT Executive Summary The accidental release prevention and emergency response policies at the stationary source The City of Winfield is committed to secure handling of chlorine gas at the water treatment plant. It is recognized that while chlorine is an indispensable part of public health protection, it poses significant hazards if not handled properly. The City of Winfield will abide by all pertinent EPA RMP regulations to guard against accidental releases of chlorine at the water treatment plant, and, if they do occur, to minimized their harm to the surrounding community and environment. Additionally, the City of Winfield will always "be on the look out" for more efficient, safer methods of handling chlorine and, as circumstances and budget allow, for a less toxic alternative disinfection regime (i.e., ozone, etc.). The stationary source and regulated substances handled Stationary source: The City of Winfield Mu nicipal Water Treatment Plant Physical location: At north edge of city limits, = mile east of Winfield Pre-release Correctional Facility on College Street Regulated substance: Chlorine Worst case release scenario Scenario Release of the contents of an entire one ton chlorine cylinder. Administrative controls and mitigation measures to limit the distance affected by the release Most of the chlorine line is on a vacuum system, if there is a break in the line, the vacuum will minimize the escape of chlorine. In the event of a release, the chlorinator(s) and/or entire water system will be shut off as needed. In the event of a release, all access doors to the chlorine room will be closed. In the event of a release, 911 will be notified immediately. The possible need for public evacuation will be stressed to 911. Alternative release scenario Scenario A pinhole leak develops in the <" aluminum from the chlorine cylinder to the manifold. This pinhole progresses to a full break in the line. Administrative controls and mitigation measures to limit the distance affected by the release Most of the chlorine line is on a vacuum system, if there is a break in the line, the vacuum will minimize the escape of chlorine. In the event of a release, the chlorinator(s) and/or entire water system will be shut off as needed. In the event of a release, all access doors to the chlorine room will be closed. In the event of a release, 911 will be notified immediately. The general accidental release prevention program and chemical specific prevention steps General accidental release prevention program All water plant employees are subject to ongoing training as treatment plant operators. Part of this training addresses chlorine handling. Generally, employees use the "buddy system" when engaged in hazardous or potential hazardous tasks. Equipment is maintained or replaced as needed to ensure no mishaps occur to equipment failure. Chemical specific prevention steps All water plan t employees are subject to ongoing training in chlorine handling. Chlorine safety information is centralized and available to employees. A hazard review has been conducted. Operating procedures for handling the chlorine cylinders have been developed. Maintenance procedures for chlorine equipment have been developed. Compliance audit procedures have been developed. Investigation procedures have been developed. The five year accident history No chlorine accidents have occurred in the five years prior to the date of this RMP plan. An emergency response program has been developed and is in place Planned changes to improve safety No changes are planned at this time. |
