Cortland Propane - Executive Summary
Executive Summary Agway Energy Products - Cortland Propane |
1. Accidental Release Prevention and Emergency Response Policies
The primary function of Agway Energy Products - Cortland Propane is to act as a propane distribution facility. By virtue of the flammable effects associated with propane, it is necessary to observe certain safety precautions in handling propane to prevent unnecessary human exposure, to reduce the threat to our own personal health as well as the health of our co-workers, and to reduce the threat to nearby members of the community. We are strongly committed to employee, public, and environmental safety. Safety at our facility depends upon the manner in which we handle propane as well as on the various safety devices incorporated into the design of our equipment. Furthermore, comprehensive training received by our employees adds to the inherent safety of our distribution facility.
This facility complies with NFPA-58 requirements for LP-Gas storage, and it is o
ur policy to adhere to all applicable federal, state, and local laws. In addition to the presence of appropriate controls to prevent possible releases of propane, if a release does occur, we are coordinated with Cortlandville Fire Department, which provides highly trained emergency response personnel to control and mitigate the effects of the release.
2. The Stationary Source and the Regulated Substances Handled
The primary purpose of this facility is to repackage and distribute propane to both retail and wholesale customers for use as a fuel. Propane arrives at our facility via transport and is stored in one 26,000-gallon storage tank. This facility has equipment for transports and equipment to load bobtails. Access to this site is restricted to authorized facility employees, authorized management personnel, and authorized contractors.
The regulated substance handled at this facility is propane. The maximum amount of propane that can be stored at this plant is 96,000 lb.
The Worst Case and Alternative Release Scenarios, Including Administrative Controls and Mitigation Measures to Limit the Distances for Each Reported Scenario
We have calculated worst case release scenarios using the EPAs RMP Comp software program. For alternative release scenario analyses, we have employed the equations provided by the EPA in the RMP Guidance For Propane Storage Facilities and used RMP Comp. The following paragraphs provide details of the chosen scenarios.
The worst case release scenario submitted for propane involves a catastrophic release from propane storage. The scenario involves the release of 96,000 lb. of propane. The release quantity has been limited by 88 percent resulting from written procedural mechanisms. It is assumed that the entire quantity of our largest propane storage tank is released as a vapor that finds an ignition source, with 10 percent of the released quantity participating in a vapor cloud explosion. Under worst case weather, the m
aximum distance of 0.4 miles was obtained corresponding to an endpoint of 1 psi overpressure.
The alternative release scenario involves a hose rupture and failure of safety devices that allows a release from propane storage resulting in a vapor cloud explosion. In this scenario, 17,056 lb. of propane is released from a 3-inch diameter hose for 1 minute. Under neutral weather conditions, the maximum distance to the 1 psi overpressure endpoint is 0.1 miles.
4. The General Accidental Release Prevention Program and Chemical-Specific Prevention Steps
Our facility has taken all the necessary steps to comply with the accidental release prevention requirements set out under 40 CFR Part 68 of the EPA. This facility was designed and constructed in accordance with NFPA-58 Standard, 1967 Edition, and state law.
The following sections briefly describe the release prevention program that is in place at our stationary source.
Agway Energy Products - Cortland Propane main
tains a detailed record of written safety information, which describes the chemical hazards, operating parameters, and equipment designs associated with all aspects of our distribution facility.
A checklist methodology is used to carry out hazard reviews at our facility. The reviews focus on operating procedures, equipment functions, and handling practices to identify possible hazards. The studies are undertaken by a team of qualified personnel with extensive knowledge of facility operations and are revalidated at regular intervals, at least every 5 years.

ed by the maintenance checks are corrected in a safe and timely manner.
Agway Energy Products - Cortland Propane will conduct audits on a regular basis to determine whether the provisions set out under the RMP rule are being implemented. These audits will be carried out at least every 3 years and any corrective actions required as a result of the audits are undertaken in a safe and prompt manner.
Agway Energy Products - Cortland Propane promptly investigates any incident that has resulted, or could reasonably result, in a catastrophic release of propane. These investigations are undertaken to identify the situation leading to the incident as well as any corrective actions to prevent the release from recurring. All reports are retained for a minimum of 5 years.
