Woodward Iodine Corporation - Executive Summary
We have adopted this Program in order to implement 40 C.F.R. 68, the federal requirements regulating Risk Management of Highly Hazardous Chemicals. |
This Program will help prevent the occurrence of, or minimize the consequences of, catastrophic releases by stating our policies and procedures for the management process hazards in start-up, operation, inspection, maintenance, and the other matters addressed in the federal standard.
The Program calls for the maximum employee participation and includes all the elements of the employee participation provisions of the standard. At a minimum, employees will: (1) participate in the development of the site specific RMP programs and will participate in their implementation, (2) participate in conducting the chlorine, ammonia, and sulfur dioxide process hazard analysis, (3) be trained annually on the RMP programs and any changes made to the program systems or processes, (4) will work with management to develop additional programs or procedures
relative to chlorine, ammonia, and sulfur dioxide process safety as needed, and (5) participate in the periodic audits of the RMP Program.
Accidental Release Prevention and Emergency Response Policies
Woodward Iodine Corporation (WIC) believes that preventative maintenance is the key to minimizing the potential for accidental releases. Standard Operating Procedures (SOPs) have been reviewed and revised to enable the employees to perform their work in a safe and efficient manner.
WIC has taken steps to educate and inform the operators, supervisors, and maintenance crews in the appropriate response to an accidental release. The training includes classroom training and operating procedures on the proper response to emergency situations.
Stationary Sources and Regulated Substances.
The WIC Facility utilizes chlorine, ammonia, and sulfur dioxide in the iodine extraction process. The maximum inventory and threshold quantities for these chemicals are shown below.
Maximum Inventory (lb.) Threshold Quantity (lb.)
Chlorine 54,000 2,500
Ammonia (anhydrous) 72,000 10,000
Sulfur Dioxide 78,000 5,000
Offsite Consequence Analysis
The offsite consequent analysis includes a worst-case scenario and an alternative release scenario as defined in 40 C.F.R 68. RMP*COMP was used to determine endpoint distances for both scenarios. The models input parameters are summarized in the table below.

Risk Management Program
WIC has compiled a Risk Management Program to minimize releases. This Program includes; safety information on the covered chemicals, hazard reviews, operating and maintenance schedules, training, compliance audits, incident investigations, and emergency response procedures.
Five-year Accident History
In the last 5 years, there have not been any accidental releases from the covered processes that resulted in deaths, injuries, evacuations,
sheltering-in-place, property damage, or environmental damage.
Planned Changes to Improve Safety
WIC has implemented a Risk Management Plan (RMP) that meets or exceeds the requirements of 40 CFR 68. It is WIC's philosophy to continually improve the safe working conditions of its employees to minimize accidents and reduce the potential for either an on-site or off-site release. With this in mind, WIC is planning on incorporating many of the RMP elements into other areas of the process not covered under 40 CFR 68 to improve the overall safety of the plant.
