CALARCO, Inc., Chamberlain Facility - Executive Summary
CALARCO Inc. |
1. Facility Accidental Release Policy
The owners, management, and employees of CALARCO Inc., Chamberlain facility (herein referred to as the Facility) at Melga Canal, Corcoran, California, 93212 are committed to the prevention of any accidental release of anhydrous ammonia. If an accidental release should occur, the facility is prepared to work with the local fire department, or other authorities to mitigate any release and minimize the impact of the release to people and the environment. A detailed emergency response plan has been developed and will be implemented in the event of an accidental release.
2. Facility Information
The primary activity at the Facility is the storage and sale of fertilizers, in addition to, the sale of pre-packaged agricultural chemicals to farmers.
Anhydrous ammonia is received, stored, and distributed for direct application for crop production nutrients.
Anhydrous ammonia is received by truck and stored in one
18,000-gallon storage tank (bullet) at the site. The maximum quantity of anhydrous ammonia handled in this process is 78,000 pounds.
3. The Worst-Case Release Scenario and Alternative Release Scenario
a. Anhydrous Ammonia Worst-Case and Alternative Release Scenarios
The worst-case release scenario is failure of the largest storage tank when filled to the greatest amount would release 78,000 pounds of anhydrous ammonia, which represents the volume of the largest storage tank at 85% capacity as limited by regulations. The distance to the endpoint (point of dispersion to 200 ppm) is 1.3 miles. The alternative release scenario, based on the PHA scenarios (or the most likely potential incident) and is a release from a broken 2-inch diameter pipe. The distance to the endpoint (point of dispersion to 200 ppm) is 0.87 miles.
4. Accidental Release Prevention Program
Anhydrous Ammonia: The Facility has implemented the provisions of the "Safety Requirements for Storage and Hand
ling of Anhydrous Ammonia, K-61.1", published by the American National Standards Institute, Inc.; California Code of Regulations, Title 8, Subchapter 1, "Unfired Pressure Vessel Safety Orders"; and the standards of the U.S. Occupational Safety and Health Administration (OSHA), 29 CFR 1910.111, "Storage and Handling of Anhydrous Ammonia."
5. Five-year Accident History
a. There have been no accidental releases or near misses of anhydrous ammonia in the past five years that:
1. Have caused any deaths, injuries, or significant property damage at the facility; nor
2. Have resulted in off-site deaths, injuries, evacuations, sheltering in place, property damage, or environmental damage.
6. The Emergency Response Program
The facility's emergency response program was written in accordance with the following regulations:
OSHA 29 CFR 1910.38;
OSHA 29 CFR 1910.120; and
Section 25503, Division 6.95 of the California Health and Safety Code
7. Planned Changes to Improve Safety
improvement is an on-going process at the facility. Periodic evaluations are performed to assess the maintenance of safe conditions. Specific planned changes to the anhydrous ammonia process at the facility are listed in the Facility PHAs.
