Southern States Cooperative- Calhoun, KY (78192) - Executive Summary
EXECUTIVE SUMMARY |
The accidental release prevention and emergency response policies at your facility:
This facility handles anhydrous ammonia, which is considered to be a regulated toxic substance by EPA. We observe all necessary safety precautions in handling anhydrous ammonia to prevent unnecessary human exposure, to reduce the threat to our own personal health and to reduce the threat to nearby members of the community. It is our policy to adhere to all applicable federal, state and local rules and regulations. Safety depends upon the manner in which we handle anhydrous ammonia, the safety devices inherent to the design of this facility, the safe handling procedures that we use and the training of our personnel.
This facility complies with ANSI K-61.1 and OSHA 1910.111 requirements for anhydrous ammonia storage. If an emergency were to occur, it is our policy to notify the local emergency response agency.
A description of your facility and the regulated substan
The primary purpose of this facility is storage. We receive anhydrous ammonia by transport truck and store it as a liquid in pressurized vessels. Access to the process is restricted to authorized employees and contractors. The maximum amount of anhydrous ammonia that can be stored at this facility is 30,000 gallons (water capacity).
The worst case and alternative release scenarios:
The worst-case release scenario is failure of one 18,000 gallon tank when filled to its maximum allowable capacity (85% @ 60 F), resulting in a release of anhydrous ammonia. The distance to the endpoint of 140 ppm is 1.95 miles, based on the dense gas dispersion model Degadis. This distance extends beyond the facility boundary and there are estimated to be 154 residents, schools, recreation areas, churches and cemeteries within the distance to endpoint.
The alternative release scenario consists of overfilling the storage tank. Two-hundred fifty pounds of anhydrous ammonia are released o
ver a period of ten minutes. The distance to the endpoint of 140 ppm is 0.16 miles, based on the dense gas dispersion model Degadis. This distance extends beyond the facility boundary and there is estimated to be one resident within the distance to endpoint.
The general accidental release prevention program and chemical-specific prevention steps:
This facility complies with EPA's accident prevention rule and all applicable state and local codes and regulations. The anhydrous ammonia system is designed, installed, and maintained in accordance with ANSI K-61.1, OSHA 1910.111 and state law.
Process Safety Information
We maintain safety information that describes the chemical hazards, operating parameters and equipment designs associated with our anhydrous ammonia storage facilities.
Process Hazard Review
Our Environmental, Health, Safety and Security (EHSS) team conducts comprehensive studies and reviews to ensure that hazards associated with our processes are identified and cont
rolled efficiently. These activities are undertaken by a team of qualified personnel with expertise in process operations and are revalidated at a regular interval. Any findings related to the hazard analysis are addressed in a timely manner.
We maintain written operating procedures for operation of the anhydrous ammonia storage facility. These procedures address various modes of operation including initial startup, normal operations, temporary operations, emergency shutdown, emergency operations, normal shutdown and startup after a turnaround. The information is readily accessible to operators.
We have a comprehensive training program in place to ensure that employees who are operating processes are competent in the operating procedures associated with these processes. Refresher training is provided at least every three years.
Our EHSS team performs thorough annual maintenance inspections on process equipment to ensure proper operations
. Basic visual inspections are performed by facility operators on a more frequent basis during loading and unloading of anhydrous ammonia delivery vehicles. Process equipment examined by these checks includes: pressure vessels, storage tanks, piping systems, relief and vent systems, emergency shutdown systems, controls and pumps. Maintenance operations are performed by qualified personnel that have been trained in safe maintenance practices. Any equipment deficiencies are corrected in a safe and timely manner.
We conduct compliance audits on a regular basis to confirm that the provisions set out under the RMP rule are being implemented. These audits are performed at least every 3 years and any corrective actions required as a result of the audits are undertaken in a timely manner.
We promptly investigate any incident that has resulted in, or could reasonably result in, a catastrophic release of anhydrous ammonia. These investigations are
undertaken to identify the situation leading to the incident as well as any corrective actions to prevent the incident from reoccurring. All reports are retained for a minimum of 5 years.
Five-year accident history:
Due to our comprehensive safety program, this facility has never had an accident involving anhydrous ammonia that caused deaths, injuries, property or environmental damage, evacuations, or shelterings in place.
The emergency response program:
It is company policy for each of our facilities to maintain an Emergency Action Plan & Emergency Response Plan. This plan addresses chemical inventory, evacuation procedures and instructions for notifying emergency response agencies. This plan is reviewed on an annual basis and is included in the employee training program. In the event of an emergency, it is our policy to notify the local emergency response agency and request that they respond to the emergency.
Planned changes to improve safety:
We will continue to implemen
t our safety program to guarantee that our facility is operated in a safe and reliable manner and to ensure the safety of our employees and the surrounding community.
