STATIONARY SOURCE AND REGULATED SUBSTANCE
Startup of the chlorine system occurred in 1982. The process is located at 10803 Brooklet, Houston, Texas 77099. The chlorine transfer process for Thunderbird Pool Service, Inc. consists of chlorine one-ton containers (maximum of 5) which are the storage vessels. Chlorine liquid is dispensed from a one ton container through a filling manifold to 20 pound cylinders (maximum of 94). The system also includes a scrubber water tank. The maximum quantity of chlorine on site is 10,000 pounds. The filling station is located under a canopy and behind a fire wall.
HAZARD ASSESSMENT SUMMARY
Worst Case Release Result Summary
Scenario Description: Release of the maximum quantity of chlorine that can be stored in a vessel - 2,000 pounds in 10 minutes. No passive mitigation measures were used. The most pessimistic meteorological conditions were used: 1.5 meters/second wind speed, and F stability. The reference table from the EPA's RM
P Guidance for Wastewater Treatment Plants was used to determine the distance to the toxic endpoint of 3 ppm. This release reaches offsite and may affect public receptors. No environmental receptors were affected by this potential release.
Alternative Release Result Summary
Scenario Description: A release of chlorine gas from 5/16 inch diameter leak. The release rate of chlorine due to the pressure of the tank is 72 pounds per minute. The meteorological conditions used were 3 meters per second wind speed, and D stability. The reference table from the EPA's RMP Guidance for Wastewater Treatment Plants was used to determine the distance to the toxic endpoint of 3 ppm. This release reaches offsite and may affect public receptors. No environmental receptors were affected by this potential release.
ACCIDENTAL RELEASE PREVENTION PROGRAM AND CHEMICAL-SPECIFIC PREVENTION STEPS
Thunderbird Pool Service, Inc. has a Process Safety Management program in place to manage the handling of
chlorine. In addition, common industry standards, policies, and procedures are utilized to ensure safe practices are being performed. This includes common practices outlined by the Chlorine Institute and the National Association of Gas Chlorinators. In addition to the Management Programs, there is a scrubber system that is used in conjunction while transferring chlorine.
FIVE YEAR ACCIDENT HISTORY
There have been no reported releases of chlorine at this facility over the last five years (6/21/94 through 6/21/99).
EMERGENCY RESPONSE PROGRAM
If a release of chlorine were to occur, Thunderbird Pool Service, Inc.'s response plan is to call 911 in order to reach the Fire Department's HAZMAT team. Employees will evacuate the facility to a point that is upwind of the hazard. Evacuation drills are performed annually. The emergency response plan provides the response organization and notification procedures, and mitigation procedures which will be implemented to respond effectively
to emergency situations that may arise at the facility. This plan will be reviewed and updated to ensure compliance with the PSM and RMP regulations, and to ensure that the plan is kept current.
