Newfolden Co-op Elevator Assn
1. Accidental Release Prevention and Emergency Response Policies
We at Newfolden Co-op Elevator Assn in Newfolden 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 Newfolden Fire Department,
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 a 30,000-gallon tank at our facility in Newfolden (Figure 1). The maximum
amount stored is 25,500 gallons (131,233 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
anhydrous ammonia storage tank (131,223 pounds) in gaseous form over a 10-minute period. At
Class F atmospheric stability, 1.5 m/s wind speed, and rural topography, the maximum distance to
a toxic endpoint of 0.14 mg/L is 12 miles (Figure 2). The estimated population within a 12-m
radius of this facility is 1,200.
The alternative release scenario involves a release from an anhydrous ammonia product line. The
scenario involves the release of 11,993.74 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 0.62 mile (Figure 3). The estimated population within a 0.62-mile radius of the
facility is 50.
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.
Process Safety Information
Newfolden Co-op Elevator Assn maintains a detailed record of safety information that describes the
chemical hazards, operating parameters, and equipment designs associated with all processes
Process Hazard Analysis
Our facility conducts comprehensive studies to ensure that hazards associated with our processes are
identified and controlled effectively. Any findings from the hazard analysis are addressed in a
Newfolden Co-op Elevator Assn maintains written operating procedures to ensure that activities
within our covered processes are conducted safely. These procedures address various modes of
operation; the information is regularly reviewed and is readily accessible to operators involved in
the processes (Appendix B).
Newfolden Co-op Elevator Assn has a comprehensive training program in place to ensure that
employees who are operating processes are competent in the operating procedures associated with
Newfolden Co-op Elevator Assn conducts documented maintenance checks on process equipment
to ensure proper operation. Maintenance checks are conducted by qualified personnel w
training in maintenance practices. Examples of process equipment that would receive maintenance
checks include: pressure vessels, storage tanks, piping systems, relief and vent systems, emergency
shutdown systems, controls, and pumps. Any equipment deficiencies identified by the maintenance
checks are corrected in a safe and timely manner (Appendix C).
Management of Change
Written procedures are in place at Newfolden Co-op Elevator Assn 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.
Newfolden Co-op Elevator Assn 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.
Newfolden Co-op Elevator Assn conducts compliance audits on a regular basis to determine whether
the plan's provisions, set out under the 40 CFR part 68, are being implemented. Any non-
compliance issue discovered during the audit is promptly corrected.
Newfolden Co-op Elevator Assn truly believes that process safety management and accident
prevention 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.
5. Five-year Accident History
Newfolden Co-op Elevator Assn has had an excellent record of preventing accidental releases over
the last 5 years. Due to our stri
ngent release prevention policies, no accidental release has occurred
during this period.
6. Emergency Response Plan
Newfolden Co-op Elevator Assn maintains a written emergency response plan to deal with
accidental releases of hazardous materials. The plan addresses all aspects of emergency response
including first aid and medical treatment, evacuations, and notification of local emergency response
agencies and the public (Appendix A).
