ADM Milling Co. - St. Louis - Executive Summary |
|
a. Accidental Release Prevention and Emergency Response Policies This facility is a flour mill which uses chlorine to bleach flour. This facility observes safety precautions in handling chlorine to reduce the threat to workers, members of the community, and the environment, and adheres to applicable Federal and state rules and regulations. Safety depends upon the manner in which the facility handles chlorine, the safety devices inherent in the design of the facility, the safe handling procedures that are used, and the training of personnel. Emergency response for this facility is coordinated with the St. Louis Fire Department HazMat Team. This includes procedures for notifying the HazMat Team in the event of an accident involving chlorine. b. The Stationary Source and the Regulated Substances Handled This facility is a flour mill. The regulated substance at this facility is chlorine. Chlorine is stored in cylinders and is used for bleaching flour. c. Off-Site Consequence Analy sis Worst-Case Scenario: As a worst-case scenario, it is assumed that the entire contents of a single chlorine cylinder is released as vapor over a ten minute period. Alternative Scenario: A more realistic release scenario involving chlorine would be a slow vapor release from a 1/4 inch hole resulting from a piping failure at a flange, joint, weld or seal. d. Accidental Release Prevention The key concepts in this facility's prevention program are employee participation, appropriate design and maintenance of equipment, and appropriate training for employees. e. Five-Year Accident History This facility has not had any accidents involving chlorine that require reporting under EPA's Risk Management Rule. f. Emergency Response Program Emergency response at this facility is coordinated with the St. Louis Fire Department HazMat Team, such that in the event of an accident, immediate emergency response measures can be implemented. g. Planned Changes to Improve Safety In July 1999, as a result of a safety review of this facility's chlorine system, this facility is planning to install a low temperature alarm with flash/strobe light to alert operators to low temperature conditions in the system, and to install flow sensors to alert operators to choke conditions in the system. |
