Boskovich Farms, Inc. - Executive Summary
1.0 EXECUTIVE SUMMARY |
The following Risk Management Program / Accidental Release Prevention Plan has been
prepared for the Boskovich Farms, Inc. (Boskovich) facility located at 711 Diaz Avenue in
Oxnard (see Figure 1). This facility is a produce preparation and distribution facility, which
operates various connected ammonia systems to cool produce prior to distribution. This
program has been prepared pursuant to Title 19, Division 2, Chapter 4.5 of the California Code
The ammonia refrigeration systems at Boskovich contain approximately 23,000 pounds of
ammonia. The maximum quantity of ammonia at the facility is approximately 33,300 pounds
due to the presence of the Aqua Ammonia Absorption Refrigeration Plant (AAARP) located on
the northeast corner of the Boskovich facility. The AAARP system is owned by Sithe Energies
and operated by E.F. Oxnard, Inc. (E.F. Oxnard). The land where the AAARP system is located
is leased from Boskovich by E.F. Oxnard. Because th
e AAARP system is owned and operated
by E.F. Oxnard, risk management and accident prevention issues pertaining to this system are
addressed in the E.F. Oxnard facility RMP documents.
In July 1993, Boskovich prepared a Process Safety Management (PSM) Plan and a Risk
Management and Prevention Program (RMPP). These documents were updated in August
1997. Boskovich's PSM and RMPP are referenced by this RMP because they contain many
of the elements required by the new RMP requirements.
1.1 Accidental Release Prevention and Emergency Response Policies
To prevent the accidental release of ammonia, Boskovich has developed the following:
- Maintenance and inspection procedures to ensure that equipment is properly maintained and
- Operating procedures to ensure that equipment is operated in a manner that minimizes the
possibility of an ammonia release.
- Employee training to ensure that operators know how to properly use the equipment and
non-operators are aware o
f the dangers of ammonia and the necessary steps to take in the
event of an ammonia release.
- The facility is secured by fencing around the site and a 24-hour guard to minimize the
possibility of a third party damaging equipment or releasing ammonia.
The programs are contained in Binder 2: Risk Management and Prevention Program.
Boskovich has prepared an Emergency Response Plan to respond to ammonia releases. In
general the plan includes:
- A list of safety equipment available at the Boskovich facility;
- Response procedures for minor leaks;
- Response procedures for major emergencies;
- Agency notification procedures; and
- Emergency procedures.
A copy of the Emergency Response Plan (ERP) for Boskovich can be found in Binder 2: Risk
Management and Prevention Program, Section 10. Further description of the ERP is contained
in Section 6.0 Emergency Response Program in this document.
1.2 Stationary Source and Substance Handled
As explained above, Boskovich operates various
ammonia cooling systems to cool produce
prior to shipment. The systems contain approximately 23,000 pounds of ammonia.
1.3 Accidental Release Scenarios
The Worst Case Scenario (WC), atmospheric release of the maximum contents of the largest
high pressure vessel (East Freezer; 4,635 lb) in 10 minutes, which is based upon Title 19 CCR
Chapter 4.5 Article 4 criteria, is considered improbable and would result in offsite impacts.
Alternate Scenario 1 (A1) is a one-minute release of a pressure safety valve (PSV) due to the
overcharging of the system from a leaking AAARP solenoid valve. This scenario also assumes
the high pressure switch fails. This scenario is considered occasional.
Alternate Scenario 2 (A2), is a five-minute release from of a PSV due to the overcharging of
the system from a leaking AAARP solenoid valve. This scenario is the same as A1, except
it assumes a slower response time by on-site safety personnel (i.e. the release occurs at
night). This scenario is co
Alternate Scenario 3 (A3), is a release from a faulty ammonia transfer hose in the Hydrovac
system. This scenario is considered possible.
In order to reduce the distance to the endpoint from an accidental release, the following
administrative controls and mitigation measures are in place at Boskovich:
- System operation and emergency response training;
- Routine maintenance schedule and procedures;
- Written operating procedures;
- Release detection sensors promote early detection of a release; and
- Security personnel who monitor the facility to ensure that no unauthorized personnel are on-
Details regarding the offsite consequence analysis for the worst case and alternative release
scenarios can be found in Section 3.0 of this document.
1.4 General Accidental Release Prevention Program Components and Substance-Specific
The following components are contained in the following sections of this Risk Management
- Offsite Consequence Analysis
- Five-year Accident History
- Program 3 Prevention Program Component
- Emergency Response Program
- Update Procedure
In order to further mitigate the effects of a ammonia release, the following risk management
components are in place:
- Maintenance and standard operating procedures for the ammonia systems.
- The site is prevented from being accessed by trespassers with the use of fencing and on-site
- Emergency Response Plan.
- Training for employees.
- Incident investigation documentation and procedures.
- Automatic system shutdowns.
- Windsock for direction of wind visible on neighboring property.
- Ammonia sensors (solid state) set at 150 ppm at various locations at the facility.
1.5 Five-year Accident History
Boskovich has had no incidents in the past five years from the ammonia system that resulted
in on site injuries that required medical attention.
1.6 Emergency Response Plan Com
The Emergency Response/Action Plan (ERP) for the Boskovich facility has been prepared and
contains information for responding to an ammonia release. The general emergency response
policy for the site when ammonia is released is to:
- Determine the severity of the release;
- Evacuate non-emergency response personnel to a safe area;
- Have two trained employees don self contained breathing apparatus (SCBA);
- Isolate and / or fix leak; and
- Notify the appropriate personnel and authorities.
1.7 Planned Changes to Improve Safety
The original RMPP plan identified recommendations, all of which have been implemented at
the facility. The RMPP plan was revised in 1997 and no additional recommendations were
identified at the time. There are currently no planned changes to improve safety.
The following recommendations have been made based on a review of Boskovich's previous
Process Hazard and Seismic Analyses, the recent Offsite Consequence Analysis, and site
- Continue to document the implementation of the RMP Program 3 prevention items.
