Olathe Potato Growers Coop
1. Accidental Release Prevention and Emergency Response Policies
We at Olathe Potato Growers Coop in Olathe 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 Montrose County Sheriff's
Department, which provides additional emer
gency 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 one 18,000-gallon and two 11,000-gallon interconnected tanks at our facility in
Olathe (Figure 1). The maximum amount stored is 34,000 gallons (174,964 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 (174,964 pounds) in gaseous form over a 10-minute period. At
Class F atmospheric stability, 1.5 m/s wind speed, and a urban topography, the maximum distance
to a toxic endpoint of 0.14 mg/L is 5.8 miles (Figure 2). The estimated pop
ulation within a 5.8-mile
radius of this facility is 3,000.
The alternative release scenario involves a release from an anhydrous ammonia product line. The
scenario involves the release of 7616.42 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 1,000.
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
Olathe Potato Growers maintains a detailed record of safety information that describes the chemical
hazards, operating parameters, and equipment designs associated with a
ll processes (Appendix D).
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
Olathe Potato Growers 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
Olathe Potato Growers has a comprehensive training program in place to ensure that employees who
are operating processes are competent in the operating procedures associated with these processes.
Olathe Potato Growers conducts documented maintenance checks on process equipment to ensure
proper operation. Maintenance checks are conducted by qualified personnel with prev
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 Olathe Potato Growers 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.
Olathe Potato Growers 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.
Olathe Potato Growers 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.
Olathe Potato Growers 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.
