Bremen Elevator Company - Executive Summary
Risk Management Plan (RMP) - Ammonia |
Farmers Union Oil Company
Bremen, North Dakota
1. Accidental Release Prevention and Emergency Response Policies
We at Bremen Elevator Company in Bremen are strongly committed to employee, public, and
environmental safety. This commitment is an inherent part of our comprehensive accidental release
prevention program that covers areas such as design, installation, operating procedures, maintenance,
and employee training associated with the processes at our facility. It is our policy to implement
appropriate controls to prevent possible releases of regulated substances. If such a release does
occur, our trained emergency response personnel are at hand to control and mitigate the effects of
the release. We also coordinate our response efforts with the New Rockford Fire Department, which
provides additional emergency response expertise.
2. Stationary Source and Regulated Substances Handled
Our facility's primary activities include support services for crop production. We have anhydrous
ammonia stored in two 30,000-gallon interconnected tanks at our facility in Bremen (Figure 1). The
maximum amount stored is 51,000 gallons (262,446 pounds) at the maximum fill capacity of 85%.
3. Worst Case Release and Alternative Release Scenarios
We utilized RMP PRO for the worst case and alternate case scenarios of the required offsite
consequence analysis for our facility. The following details these scenarios.
The worst case release scenario involves a catastrophic release of the entire contents of the
interconnected anhydrous ammonia storage tanks (262,446 pounds) in gaseous form over a 10-
minute period. At Class F atmospheric stability, 1.5 m/s wind speed, and urban topography, the
maximum distance to a toxic endpoint of 0.14 mg/L is 7.5 miles (Figure 2). The estimate
population within a 7.5-mile radius of this facility is 175.
The alternative release scenario involves a release from an anhydrous ammonia product line. The
scenario involves the release of 7,616.42 pounds of ammonia in a gaseous form over a period of 30
minutes. Under neutral weather conditions, the maximum distance to the toxic endpoint of 0.14
mg/L of ammonia is 0.31 mile (Figure 3). The estimated population within a 0.31-mile radius of the
facility is 15.
4. General Accidental Release Prevention Program
Our facility has taken all the necessary steps to comply with the EPA's accidental release prevention
requirements as set forth in 40 CFR part 68. The following sections briefly describe the elements
of the release prevention program that is in place at our stationary source.

checks are corrected in a safe and timely manner (Appendix C).
Management of Change
Written procedures are in place at Bremen Elevator Company to manage changes in process
chemicals, technology, equipment, and procedures. Process operators, maintenance personnel or
other employees whose job tasks are affected by a modification in process conditions are promptly
notified of the modification and offered training to deal with it.
Bremen Elevator Company routinely conducts pre-startup safety reviews related to new processes
and modifications in established processes. These reviews are conducted to confirm that
construction, equipment, and operating and maintenance
procedures are suitable for safe startup prior
to placing equipment into operation.

is a team effort. Company employees are strongly encouraged to express their views concerning
accident prevention issues and to recommend improvements. In addition, our employees have access
to all information created as part of the facility's implementation of the RMP, particularly
information resulting from process hazard analyses.
