EXECUTIVE SUMMARY- Anhydrous Ammonia 
This facility complies with the 1989 ANSI K 61.1 "Safety Requirements for the Storage and Handling of Anhydrous Ammonia". In addition, it is our policy to adhere to all applicable federal, state and local laws.  
Terra's Corporate Mission states "To provide for the safety of our employees, our custome 
rs and the general public". In order to fulfill this mission, Terra provides a corporate EHS group to maintain and administer comprehensive safety and environmental programs and procedures. EHS field safety services supervisors audit and monitor facility compliance with the safety standards of the company.  
All locations are required to conduct their own internal audit utilizing checklist survey forms that are reviewed regularly and updated as necessary to ensure all applicable federal state and local regulations are covered. The EHS group conducts comprehensive annual audits at every location to measure regulatory compliance including those governing the safe handling and storage of anhydrous ammonia. The field supervisors require a timely written response with the completion date of all recommendations resulting from the audits. 
Each location has a 'site safety coordinator' as an extension of the EHS group. These coordinators are given training to monitor the day to day safe work  
activities, maintain the required regulatory record keeping, conduct monthly safety meetings, conduct employee training and act as the location's contact with the corporate EHS group. The site safety coordinators act as the location emergency contact. 
This facility is a wholesale farm supply distribution center. We store and distribute a wide variety of pesticides and fertilizers including anhydrous ammonia. Anhydrous ammonia is received by truck, is handled and stored on-site and is a regulated substance by the EPA requiring us to comply with the Risk Management Program. Ammonia is used for blending into mixed grade fertilizers for crop production nutrients. 
Anhydrous ammonia is stored in one stationary storage tank @ 12,000 gallons on site.  56,000 pounds of anhydrous ammonia is the maximum storage capacity of stationary storage tanks.  The total facility anhydrous ammonia storage capacity for our facility is  5 
6,000 pounds.  The largest single storage vessel at our facility contains 56,000 pounds. 
Our worst case scenario is the loss of the total contents of the 12,000 gallon storage tank, when filled to the greatest amount allowed (85% of capacity), released as a gas over 10 minutes, resulting total vaporization. The maximum quantity released would be 56,000 pounds. According to DEGADIS modeling, this release (distance to point of dispersion to 200 PPM) would have off site impact. It should be noted that Terra distribution has never had a release of an entire stationary storage tank. 
The most common alternative release scenario(s) from our facility would not reach an end-point off-site. The alternative release scenario modeled for the purposes of this plan is a 2-minute release from a stationary storage tank representing a valve and hose failure requiring a manual shut down.  The total amount of anhydrous ammonia released in this sce 
nario would be 12,000 pounds. This release scenario (distance to point of dispersion to 200 PPM) would have off site impact.  It should be noted Terra has not had a release of this type from any distribution facility. 
The ammonia system is designed, installed and is maintained in accordance with ASTM standards and the ASME codes. This facility complies with the ANSI K 61.1 standards (1989), OSHA (29 CFR 1910.111), EPA's Accidental Release Prevention Rule as well as all applicable federal, state and local codes and regulations. 
Our ammonia system is protected from major releases by internal excess flow valves, check valves, relief valves, manual shutoffs and emergency shutoff valves.  All of the main storage tank valves are locked when not in use. 
Our ammonia system is inspected on a regular basis with maintenance and preventive maintenance scheduled and documented. Liquid and vapor valves, hos 
es, excess flow valves, gauges, and relief valves are replaced when necessary and/or according to the guidelines in the ANSI standards. 
Training is provided to all employees at least annually, whenever there is a change in the process or whenever competency with the regulations is questioned. The training consists of classroom lecture, current videos, testing and certification and on the job training.  
There has been no accidents involving anhydrous ammonia that caused deaths, injuries, property or environmental damage including evacuations on or off-site. 
In the event of an emergency involving our ammonia system, it is our policy to notify the local community fire department and request that they respond to the emergency. In preparation for this, we have coordinated with all of the local response agencies by providing information and facility tours to ensure that they are familiar with and properly prepared for an inci 
dent at our facility. This will help to ensure that our community has the strategy for responding to and mitigating the threat posed by an ammonia release. This complies with the requirement for our facility to be included in the community emergency response plan prepared under EPCRA and coordinated with our LEPC. 
In addition, Terra has an Emergency Response and Contingency Plan for each facility that complies with the requirements of OSHA (29 CFR 1910.38 and 1910.1200). The plan includes public notification, provisions for initial medical care, evacuations and LEPC coordination. 
We do not plan to make any changes to the physical site. We will continue to provide our employees with ongoing annual training to ensure that they are current with all of the safe ammonia transfer and handling procedures, and provide regular inspection and maintenance on all of the ammonia equipment.
