Midway Anhydrous Facility - Executive Summary
Accidental Release Prevention and Emergency Response Policies: The owners, management and employees of the Midway Anhydrous Facility are committed to providing a safe workplace free of accidental releases of anhydrous ammonia. Health safety and environmental compliance are a fundamental part of every employee's job. It is facility policy to adhere to applicable Federal, State and Local laws and to implement appropriate controls to prevent accidental releases of anhydrous ammonia. If an accidental release were to occur, the facility would respond in accordance with it's Emergency Response Plan and is prepared to work with the local fire department, the Local Emergency Planning Committee and other authorities to control and mitigate the release and minimize the impact of the release to employees, the environment and the general public. |
Stationary Source and Regulated Substances Handled: The primary activity at this facility (the stationary source) is the storage and handling of anh
ydrous ammonia for direct sale to farmers. The maximum stored quantity of anhydrous ammonia is approximately 149,280 pounds stored in one 18,000 and one 12,000 storage tanks. The maximum fill level of the tanks is 85% of the total tanks capacity, which is controlled by a liquid level gauge.
Worst Case Release Scenario and Alternate Release Scenario: The worst cast scenario would be the release of the total contents of the storage tanks releases as a gas over 10 minutes. The maximum quantity released would be 149,280, which represents the volume of storage at 85% of capacity as limited by design standards. The distance to the endpoint is 4.4 miles. The alternate release scenario involves the release of anhydrous ammonia from a breakdown/rupture in a three (3) inch hose during transfer of ammonia from the storage tanks to a nurse tank. The quantity of ammonia released as a gas would be approximately 95 pounds.
The Accidental Release Prevention Program: The facility complies wi
th the EPA's accidental release prevention requirements and applicable State and Local codes and regulations.
The Five Year Accident History: There have been no accidental releases of anhydrous ammonia in the past 5 years that: Have caused any deaths, injuries, of significant property damage at the facility, nor to our knowledge, have resulted in offsite deaths, injuries, evacuations, sheltering in place, property damage or environmental damage.
The Emergency Response Program: The facility has a written emergency response action plan, provided local authorities the plan and SARA Title III, and includes pre emergency planning and employee training.
Planned Changes to Improve Safety: Safety improvements is an ongoing process at the facility. Periodic evaluations are performed to assess the maintenance of safe conditions. There are no additional specific anhydrous ammonia safety recommendations for implementation at this time.
