RISK MANAGEMENT PLAN EXECUTIVE SUMMARY FARMLAND INDUSTRIES, INC. GRANT, NE TERMINAL Farmland's Grant, NE, fertilizer facility is located on nearly 10 acres in southwestern Nebraska, about 17 miles from the Colorado border. The terminal functions as a mixing, storage and distribution facility for the fertilizer used by Farmland's 600,000 producer-members to grow the crops that provide high-quality, low-cost food for families around the world. Facility snapshot Annual volume of 2,250 tons of ammonia, used primarily in mixing, and 56,000 tons of liquid fertilizer is distributed through this Farmland facility that has been supplying co-ops in western Nebraska for 25 years. The Grant facility provides a vital link in the chain of Farmland inputs. Anhydrous ammonia, produced at Farmland's nitrogen manufacturing facilities, is shipped to the Grant facility where it is used to make starter fertilizers for local co-ops. By eliminating much of the shipping costs for the co-ops, the termi nal helps contain the cost of fertilizer for Farmland member-owners as well as provide a convenient location for them to get their product. Impact on the community Farmland is a solid, reliable member of the Grant community. Its employees are committed to customer service and the facility is available to service member-owners as needed throughout the year. Farmland's Grant employees know their customers are also their neighbors and strive to "always be there if someone needs us." Employee snapshot Farmland has five full-time employees with more than 25 years of combined operating experience at its Grant facility. Although few in number, these employees have a large impact on the community in which they live. They have conducted facility tours for the local schools as well as the Local Emergency Planning Committee. Farmland employees recognize community involvement and volunteerism as the most effective way to improve the communities they live in.

Risk Management Program This facility is subject to the Environmental Protection Agencies Risk Management Program Rule under the Clean Air Act Amendments of 1990. The Risk Management Program Rule require facilities handling threshold amounts of certain substances to develop a Risk Management Program and submit a Risk Management Plan. The Program requirements include submission of the risk management plan, hazard assessments defining possible off-site impacts of certain regulated substance release scenarios, a five-year accident history, development of a process accidental release prevention program, and an emergency response program. The following is the Executive Summary of the Risk Management Program for Farmland Industries, Inc.; Grant Fertilizer Terminal at Grant, Nebraska. Stationary Source and Regulated Substances Initial construction and operation of the Grant Fertilizer Terminal began in 1974. Several changes, additions and improvements since that time have resulted in the current design of the facility. The anhydrous ammonia received and stored at this facility is used in the formulation of liquid fertilizers. The Grant Fertilizer Terminal is a distribution facility for liquid fertilizers consisting of (2) 30,000,and (1) 12,000 gal pressurized ammonia storage vessel, 10-34-00 reactor, cooling tower, assorted liquid fertilizer storage tanks, miscellaneous vessels and piping. Ammonia is deliveried to the facility by rail car. Anhydrous Ammonia is the only substance, regulated by the EPA's RMP rule, that is used, or stored at the Grant's facility. The ammoina storage and 10-34-00 mixing process is subject to the rule as a program 3 process. Accidental release prevention and Emergency Response Policy It is Farmland's corporate policy to eliminate accidental releases of any substance, in particular hazardous and regulated materials. The management and employees of this facility are committed to the prevention of any accidental releases. Accidental release prevention is critical to the safe operation of this terminal, the safety of its employees and the community. To achieve its accident and accidental release prevention goals, Farmland is committed to the following: * A knowledgeable, motivated and highly trained employee group * A well-designed facility that is maintained and operated in a superior manner * Implementation of a Comprehensive Process Safety Management and Prevention Program * Continual review and improvements that enhance safety and accident prevention * Excellence in safety programs and practices, and a superior safety and accident record * Planning, preparation and training for emergency response The Grant terminal has had a written Emergency Response Plan, as required by the RMP and other EPA and Occupational Safety and Health Administration (OSHA) rules, in effect for many years, and is committed to implement the plan in response to any accidental release to minimize the impact to employees, the community and the environment. The response plan is coordinated with the Local Emergency Response committee and emergency response agencies. Terminal personnel have interacted with these agencies for many years regarding the plan and activities at the terminal. The local emergency planning commitee represenatives have visited and toured the facility Employees are trained in the implementation of the plan and appropriate response activities that could be required in the event of an emergency. Prevention program The Grant fertilizer terminal is subject to the OSHA Process Safety Management (PSM) rule, 29CFR1910.119. This rule has required this facility to establish an accident prevention program which is equivalent to that required for Program 3 processes under the EPA's RMP rule. The OSHA PSM/EPA Prevention Program consists of a set of facility management policies and procedures that promote and recognize process safety and the prevention of accidents in processes that handle, use, store or process hazardous materials. The procedures provide accident prevention process controls to all aspects of this process activities. The Grant terminal adheres to the requirements of PSM and has written policies and procedures addressing all aspects of PSM and EPA Prevention Program requirements including routine training and testing of employees and drivers that operate any part of the process. The facility has addressed the elements of accident prevention included in these programs throughout its years of operation. The facility is diligent in adhering to and maintaining its Process Safety/Prevention Program. Emergency Response Program The Grant Ammonia Terminal has established an Emergency Response Program and has a written Emergency Response Plan as required by the Risk Management Program rule and other Environmental Protection Agency and OSHA rules. This plan is coordinated with the local community response plan and is available to those responding agencies. The facility is included in the community emergency reponse plan. This facility is an active participant in the Local Emergency Planning Committee and interacts with various local agencies in its emergency planning. These include local fire departments, law enforcement agen cies and hospitals. Employees receive annual training on the facility emergency response plan and also receive additional safety training, both in general, and in the competencies relative to their required roles in the emergency response plan. Five-year accident history The RMP rule requires inclusion of the facility's five-year accident history for all accidental releases of regulated substances that resulted in deaths, injuries or significant property or environmental damage on or off site. Farmland's Grant terminal has an excellent five-year accident record with no RMP reportable releases. Hazard Assessment Synopsis of worst and alternative-case release scenarios: The hazard assessment element of the RMP rule requires the evaluation of potential off site effects of "worst-case" and "alternative-case" release scenarios of regulated substances in a program 3 process. The EPA has defined a worst-case scenario as the release of the largest quantity of a listed chemical from a vessel or process line failure, taking into account passive mitigation and administrative controls. The impact of these potential releases must be quantified in accordance with release criteria dictated in the rule. The projected impact distance is determined using EPA defined atmospheric conditions and is intended to provide a conservative estimate of the maximum possible area that might be affected. According to the EPA, the worst-case scenario is intended to ensure that no potential risks to public health are overlooked, but the distance to an endpoint estimated under worst-case should not be considered a "public danger zone." Possible causes or the extreme improbability that such releases may occur are not considered. The alternative release scenario definition is a release that is more likely to occur than the worst-case release; however, as with the worst-case, the alternative release improbability is not taken into consideration. Worst Case Toxic Release - Anhydrous Ammonia Ammonia is a colorless gas with a strong pungent odor, and is one of the most widely used industrial chemicals. It is prepared industrially from natural gas, steam and air. Some of this ammonia is used for direct injection into croplands as a fertilizer. A large amount of industrial ammonia is reacted with carbon dioxide to make urea fertilizer, or reacted to make ammonium nitrate fertilizer. Ammonia is also frequently used as a refrigerant for the storage of perishable foods. Ammonia vapors can be irritating to the nose, throat, eyes and skin. Direct liquid contact to the skin can cause severe burns. Farmland's hypothetical worst-case scenario involves an anhydrous ammonia release from an 80 ton rail car unloading at the facility. The worst case release assumes, as required by the rule, that this entire quantity is released as a result of a catastrophic failure of the tank car, in 10 minutes. This unlikely event was modeled with a publicly available model (DEGADIS) which ha s been demonstrated to provide reasonable estimates of concentrations and distances associated with this type of release event. The impact of this release scenario is predicted to extend beyond the facility boundary and impact public receptors. This scenario, we believe, is a hypothetical worst-case event dictated by the rule and extremely unlikely to occur for many reasons. In addition to the stringent design controls for this type of pressurized vessel, facility maintenance and inspection programs address the integrity of process and storage vessels, and largely preclude such massive and unlikely failures. Alternate Case Toxic Release - Anhydrous Ammonia More likely release events than the hypothetical worst-case, tend to concentrate in areas where the ammonia product is handled such as loading and other transport activities. Generally, significantly lower quantities are involved, due to numerous shutdown safeguards present, as they are through out the terminal, and operator in tervention which tend to mitigate and limit the consequences of failures. The hypothetical ammonia alternative release scenario considered for this process is, a release of ammonia due to the failure of a 1.25" liquid hose. The hose is assumed to fail and release ammonia for a few seconds before automatic shutoff valves on the rail car and tank activate and stops the release. The impact of such a release was modeled with the DEGADIS model which shows that, under typical ambient conditions, the impact of the release would extend off-site. Planned Changes for Safety Improvements Safety improvements are a continual and ongoing process at the facility which is facilitated by the Prevention Program/Process Safety Management Program. A formal process hazard analysis revalidation is conducted at least every five years, but review is constant through management of change procedures, operator training, incident investigation and mechanical integrity programs. As a result, changes relevan t to safety occur continuously as needs are identified through these procedures and policies. |
