Harcros Chemicals Inc. -- Shreveport - Executive Summary
1921 LDEQ Facility ID Number
1. Accidental release prevention and emergency response policies
At this distribution facility, we store chlorine, sulfur dioxide and hydrofluoric acid 70%, which are considered hazardous by the EPA. The same properties that make chlorine, sulfur dioxide, and hydrofluoric acid valuable as commodity chemicals also make it necessary to observe certain safety precautions to prevent unnecessary human exposure, to reduce the threat to our own personal health as well as that of our co-workers, and to reduce the threat to nearby members of the community. It is our policy to adhere to all applicable Federal and State rules and regulations. Safety depends upon the manner in which we handle chlorine and sulfur dioxide, the safety devices inherent in the design of this facility, the safe handling procedures that we use, and the training of our personnel.
Our emergency response program is based upon the Chlorine Institute's Pamph
let 64, Emergency Response Plans for Chlorine Facilities. The emergency response plan includes procedures for notification of the local fire authority and notification of any potentially affected neighbors.
2. The stationary source and regulated substances handled
One of the primary purposes of this facility is to store chlorine, sulfur dioxide, hydrofluoric acid 70% for distribution to our customers which include water treatment facilities and general industry. Chlorine and sulfur dioxide are received in 150 pound cylinders and 2,000 pound containers and are shipped in the same packages. Hydrofluoric acid is received in 550 pound drums and is shipped in the same packages. Access to the site is restricted to facility employees, management personnel, and authorized contractors and visitors. The maximum total inventory of chlorine stored at this facility is 94,500 pounds. The maximum total inventory of sulfur dioxide stored at this facility is 72,000 pounds. The maximum total
inventory of hydrofluoric acid 70% is 4,400 pounds. Average inventories are much less.
3. The worst-case release scenario and the alternative release scenarios, including administrative controls and mitigation measures to limit the distance for each reported scenario
Worst-Case Scenario - Failure of a 2,000 pound container of chlorine. It is assumed that the entire contents are released and vaporized in 10 minutes. The distance to the endpoint of 0.0087 mg/L is 1.3 miles as determined by the EPA's "RMP Comp" computer program.
Alternative Release Scenario (Chlorine) - The same as the Worst-Case scenario except the contents of the ton container are released during "average" weather conditions. This scenario is unlikely but provides a reasonable basis for emergency planning purposes. The distance to the toxic endpoint of 0.0087 mg/L (as determined by RMP Comp) is 0.30 miles.
Alternative Release Scenario (Sulfur Dioxide) - This scenario is the same as the alternate release
scenario for chlorine. A 2,000 pound container releases its entire contents in ten minutes. Again, this is very unlikely to happen and is being used for emergency planning purposes. The distance to the toxic endpoint of 0.0078 mg/L is 0.20 miles as determined by RMP Comp.
Alternative Release Scenario (Hydrofluoric Acid 70%) - A 550 pound drum releases its entire contents inside the warehouse in ten minutes. The distance to the toxic endpoint of 0.016 mg/L is 0.10 miles as determined by RMP Comp.
