|
Morton Salt - Port Canaveral Facilitiy Risk Management Plan (RMP) for Propane Usage To the best of the undersigned's knowledge, information, and belief formed after reasonable inquiry, the information submitted is true, accurate, and complete. Mr. Michael L. Markley (Name) Signature Facility Manager (Title) Date Executive Summary Accidental Release Prevention and Emergency Response Policies: This facility complies with NFPA-58 and ASME requirements for LP-Gas storage, and it is our policy to adhere to all applicable federal, state and local laws. If an emergency were to occur it is our policy to notify the Cape Canaveral Volunteer Fire Department and request that they respond to the emergency. We have discussed this policy with th e fire department and they are familiar with our facility including the propane system. This facility processes and packages bulk salt, primarily for use in residential water softening units. Bulk salt is received from the company's solar evaporation facility in the Bahamas. A propane fired dryer is used to finish drying the product. The drying system consists of six 1000 gallon propane tanks and associated piping, valves, and a burner. In addition, a 250 gallon tank of propane is used for refilling forklift cylinders. The six tanks, which are located 100 feet northeast of the main building, are connected to the salt dryer by a two inch underground supply line. Safety devices are installed on the system, including double backflow check filler valves, fixed maximum liquid level gauges, manual shutoff valves, pressure relief valves, and perimeter crash posts around the storage tanks. Worst Case Scenario: The worst case scenario is failure of one 1000 gallon storage tank when fi lled to the greatest amount allowed (88%) which results in a vapor cloud explosion. According to EPA's look-up tables, the distance to the endpoint 0.1 miles. The public receptor potentially impacted within this radius is a pier and part of the harbor. No residential or business buildings, other than those belonging to Morton Salt, are located within this radius. Alternative Scenario: The alternative scenario evaluated is a hose rupture in a transfer hose. The estimated distance to the endpoint of such a release is 126 feet or 0.023 miles. No residents, public receptors or environmental receptors are located within this radius. Accident History: This facility has never had an accident involving propane that caused death, injury, property or environmental damage, evacuation or sheltering in place. Planned changes to improve safety: In order to comply with the RMP, we have implemented additional reviews of operation and maintenance procedures and compliance audits with respe ct to propane. Morton Salt has also reviewed the procedures employed by the contractor (Amerigas) which supply the propane. Physical changes currently planned include replacement of the the 7 propane storage tanks with refurbished ASME certified tanks by 5/31/99. |
