The maximum inventory of Ammonia (anh
ydrous) at our facility is 18088.00 lb..
3. The Worst Case Release Scenario(s) and the Alternative Release Scenario(s), including administrative controls and mitigation measures to limit the distances for each reported scenario
To perform the required offsite consequence analysis for our facility, we have used the EPA's RMP Guidance for Ammonia Refrigeration Reference Tables or Equations. The following paragraphs provide details of the chosen scenarios.
The worst case release scenario submitted for Program 2 and 3 toxic substances as a class involves a catastrophic release from Ammonia Refrigeration. In this scenario 10615 lb. of Ammonia (anhydrous) is released. The toxic liquid released is assumed to form a 1 cm deep pool from which evaporation takes place. The entire pool is estimated to evaporate over 10 minutes. At Class F atmospheric stability and 1.5 m/s windspeed, the maximum distance of 2.18 miles is obtained corresponding to a toxic endpoint of 0.14 mg/L.
l worst case release scenario for Program 2 and 3 toxics, involving a catastrophic release from Ammonia Refrigeration, is also included in the RMP. In this scenario 7473 lb. of Ammonia (anhydrous) is released. The toxic liquid released is assumed to form a 1 cm deep pool from which evaporation takes place. The entire pool is estimated to evaporate over 10 minutes. At Class F atmospheric stability and 1.5 m/s windspeed, the maximum distance of 1.59 miles is obtained corresponding to a toxic endpoint of 0.14 mg/L.
The alternative release scenario for Ammonia (anhydrous) involves a release from Ammonia Refrigeration. The scenario involves the release of 1000 lb. of . Toxic liquid is assumed to be released to form a 1 cm deep pool from which evaporation takes place. The entire pool is estimated to have evaporated after 60 minutes. The release is also assumed to be controlled by neutralization and emergency shutdown system(s). Under neutral weather conditions, the maximum distance
to the toxic endpoint of 0.14 mg/L of Ammonia (anhydrous) is 0.07 miles.
4. The General Accidental Release Prevention Program and the 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. The following sections briefly describe the elements of the release prevention program that is in place at our stationary source.
Process Safety Information
Maine Wild Blueberry Inc maintains a detailed record of safety information that describes the chemical hazards, operating parameters and equipment designs associated with all processes.
Process Hazard Analysis
Our facility conducts comprehensive studies to ensure that hazards associated with our processes are identified and controlled efficiently. The methodology used to carry out these analyses is What If/Checklist (
combined) and HAZOP. The studies are undertaken by a team of qualified personnel with expertise in engineering and process operations and are revalidated at a regular interval of every 3 years . Any findings related to the hazard analysis are addressed in a timely manner. The most recent PHA/update was performed on 07/31/1998.
For the purposes of safely conducting activities within our covered processes, Maine Wild Blueberry Inc maintains written operating procedures. These procedures address various modes of operation such as initial startup, normal operations, temporary operations, emergency shutdown, emergency operations, normal shutdown and startup after a turnaround. The information is regularly reviewed and is readily accessible to operators involved in the processes.
Maine Wild Blueberry Inc has a comprehensive training program in place to ensure that employees who are operating processes are competent in the operating procedures associated w
ith these processes. Refresher training is provided at least every year and more frequently as needed.
Maine Wild Blueberry Inc carries out highly documented maintenance checks on process equipment to ensure proper operations. Process equipment examined by these checks includes among others; pressure vessels, storage tanks, piping systems, relief and vent systems, emergency shutdown systems, controls and pumps. Maintenance operations are carried out by qualified personnel with previous training in maintenance practices. Furthermore, these personnel are offered specialized training as needed. Any equipment deficiencies identified by the maintenance checks are corrected in a safe and timely manner.
Management of Change
Written procedures are in place at Maine Wild Blueberry Inc to manage changes in process chemicals, technology, equipment and procedures. The most recent review/revision of maintenance procedures was performed on 06/29/1998. Process operators,
maintenance personnel or any other employee whose job tasks are affected by a modification in process conditions are promptly made aware of and offered training to deal with the modification.
Pre-start up safety reviews related to new processes and to modifications in established processes are conducted as a regular practice at Maine Wild Blueberry Inc. The most recent review was performed on 08/01/1998. These reviews are conducted to confirm that construction, equipment, operating and maintenance procedures are suitable for safe startup prior to placing equipment into operation.
Maine Wild Blueberry Inc conducts audits on a regular basis to determine whether the provisions set out under the RMP rule are being implemented. The most recent comliance audit was conducted on 06/29/1998. These audits are 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.
Maine Wild Blueberry Inc promptly investigates any incident that has resulted in, or could reasonably result in a catastrophic release of a regulated substance. These investigations are undertaken to identify the situation leading to the incident as well as any corrective actions to prevent the release from reoccurring. All reports are retained for a minimum of 5 years.
Maine Wild Blueberry Inc truly believes that process safety management and accident prevention is a team effort. Company employees are strongly encouraged to express their views concerning accident prevention issues and to recommend improvements. In addition, our employees have access to all information created as part of the facility's implementation of the RMP rule, including information resulting from process hazard analyses in particular.
On occasion, our company hires contractors to conduct specialized maintenance and construction activities. Prior to s
electing a contractor, a thorough evaluation of safety performance of the contractor is carried out. Maine Wild Blueberry Inc has a strict policy of informing the contractors of known potential hazards related the contractor's work and the processes. Contractors are also informed of all the procedures for emergency response should an accidental release of a regulated substance occur.
