Risk Management Plan
Water Treatment Plant
1. Accidental Release Prevention and Emergency Response Policies
All water plant operating employees are to be trained on the proper handling of Chlorine tanks and feed systems, and emergency response contact policies in a timely fashion following their employment at the facility, and will receive refresher training on an annual basis thereafter.
An outside agency (Connersville Fire Department) is to be notified in the event of a potential or actual release of Chlorine outside the facility. The Fire Department will be responsible for any necessary notifications of the public and/or trained and equipped hazardous materials responders.
2. Stationary source and regulated substance(s)
The Connersville Utilities owns and operates a water treatment plant in Connersville, Indiana. It uses Chlorine stored in 2,000-pound cylinder tanks.
Chlorine gas is drawn from the tanks using a low-pressure water
induction system for injection a various points in the water treatment system.
No more than three (2) 2,000-pound tanks are on-hand at any time, for a maximum total quantity of 4,000 pounds of Chlorine.
3. Worst Case Scenario
The worst case scenario is the rupture of one cylinder tank containing 2,000 pounds of Chlorine.
The contents of the cylinder tank would be released as Chlorine gas at a rate of 200 pounds per minute over a period of ten (10 minutes). The total quantity released would be 2,000 pounds.
The distance to toxic endpoint is calculated at .9 miles using RMP Comp as the modeling calculation tool.
4. Alternative Case Scenario
A portion of the contents of the cylinder tank would be released as Chlorine gas at a rate of 2 pounds per minute over a period of 30 minutes. The total quantity released would be 60 pounds.
The distance to toxic endpoint is calculated at .1 miles using RMP Comp as the modeling calculation tool.
5. General Accidental Release Prevention
Program and Chemical-Specific Prevention Steps
The accidental release prevention program is based upon a combination of management practices and low pressure vacuum feeders specifically designed for Chlorine gas.
6. Five-Year Accident History
The Connersville Utilities Water Treatment Plant has had no accidental releases of Chlorine gas in the past five (5) years.
7. Emergency Response Program
The Connersville Utilities Treatment Plant is not required to have an emergency response program since response activities will be handled by public responders.
