2. The stationary source and regulated substance handled:
The primary function of this facility is corn wet milling. Sulfur dioxide is injected in to the steeping water to aid in the steeping process. Sulfur dioxide is received by truck transport and stored in a pressured tank. The storage tank is located on the second floor of the mill building in an enclosed room. The sulfur dioxide system falls under OSHA's Process Safety Management Program and complies with the Process Safety Management Program requirements. The process is manned 24 hours a day 365 days a year.
The maximum amount of sulfur dioxide that can be stored at this plant is 66,000 pounds.
3. The worst-case release scenario and the alternative release scenario, including administrative controls and mitigation measures to limit the distances for each reporting scenario:
Worst Case Scenario: Failure of the sulfur
dioxide storage tank when filled to the greatest amount allowed by company policy. The amount of sulfur dioxide that would be released in the storage room would be 66,000 pounds. The distance to the endpoint of 1psi for the worst-case scenario is 20 miles.
Alternative Scenario: Unloading hose failure 30-foot length of 4-inch hose. The excess flow valve function to stop flow. The contents of the unloading line are released. The distance to the endpoint for the lower toxic limit for the alternative scenario is 0.31 miles. This release has the possibility of extending beyond the facility boundary.
4. The general accidental release prevention program and the specific prevention steps:
This corn wet milling facility complies with EPA's Accidental Release Prevention Rule, OSHA's Process Safety Management Program and with all applicable state and local codes and regulations. The sulfur dioxide system was designed and constructed in accordance with ASME pressure vessel code. All of our e
