                      Executive Summary 
                  Olathe Potato Growers Coop 
                       Olathe, Colorado 
 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.

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. 
Pre-startup Reviews 
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.
