ACCIDENTAL RELEASE PREVENTION AND EMERGENCY RESPONSE POLICIES 
 
Splash Pool Chemicals of Arizona, Inc. has an emergency action plan in effect.  The Emergency Action Plan (Plan) was designed to meet the following objectives: 
 
   1.)    To save lives. 
   2.)    To minimize and avoid injuries. 
   3.)    To protect the environment. 
   4.)    To minimize property damage. 
 
Splash Pool Chemicals of Arizona, Inc. maintains a safety committee whose members are the designated emergency coordinators for the facility.  The Plan provides the response organization and notification procedures, evacuation routes, chlorine health hazards, and mitigation procedures which will be implemented to respond effectively to emergency situations that may arise at the facility.  This Plan is reviewed and updated at least once per year.  This Plan was reviewed and updated to ensure compliance with the PSM and RMP regulations, and to ensure that the plan is kept current. 
 
STATIONARY SOURCE AND REGULATED SUBSTANCE 
 
The process is locate 
d at 3144 East 46th Street, Tucson, Arizona  85713.  The chlorine transfer process for Splash Pool Chemicals of Arizona, Inc. consists of chlorine one-ton containers which are the storage vessels.  Chlorine liquid is dispensed from the one ton container through a filling manifold to a 20 pound cylinder.  
 
The maximum quantity of chlorine on site is 12000 pounds. 
 
There are three full time employees on site; however, there are seven additional employees that pick up supplies in the morning and are on the road all day.  They may stop back at the end of the day to unload the vehicle. 
 
HAZARD ASSESSMENT SUMMARY 
 
Worst Case Release Summary: 
The worst case release for this facility was that of the maximum quantity of chlorine that can be stored in a vessel. The largest vessel, one-ton container, has a maximum capacity of 2,000 pounds. This quantity was released in 10 minutes.  The chlorine containers are stored outside; therefore, no passive mitigation measures were incorporated into the rel 
ease rate calculations.  The most pessimistic meteorological conditions were used: 1.5 meters/second wind speed, and F stability.  The facility is located in an urban setting.  The downwind distance to 3 ppm was determined using Exhibit 4-3 from the EPA "Risk Management Program Guidance for Wastewater Treatment Facilities", November 1998. The release reaches off-site and may affect population receptors.  No environmental receptors are affected by this potential scenario. 
 
Alternative Release Result Summary: 
The alternative release scenario was that of a 5/16 inch diameter two phase leak of chlorine until the one ton container was empty (28 minutes).  This scenario was chosen because it is possible for a small hole this size to occur in piping.  Again, the piping is located outside the building, therefore, no passive mitigation measures were incorporated into the release rate. The meteorological conditions used were 3 meters/second wind speed, and D stability.  The facility is located i 
n an urban setting.  The downwind distance to 3 ppm was determined using Exhibit 4-12 from the EPA "Risk Management Program Guidance for Wastewater Treatment Facilities", November 1998. The release reaches off-site and may affect population receptors.  No environmental receptors are affected by this potential scenario. 
 
 
ACCIDENTAL RELEASE PREVENTION PROGRAM AND CHEMICAL-SPECIFIC PREVENTION STEPS 
 
Splash Pool Chemicals of Arizona, Inc. has a Process Safety Management program in place to manage the handling of chlorine. Splash Pool Chemicals of Arizona, Inc. does not use any outside contractors at the facility; therefore, they do not have a contractor safety program in place.  In the event that they need to use outside contractors, a safety program will be prepared and implemented at that time.   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 an 
d the National Association of Gas Chlorinators. 
 
All employees must complete a safety training program which includes materials published by the National Association of Gas Chlorinators and The Chlorine Institute.  Only employees who have completed training certification for "Level 2 Technician" status may transfer chlorine to 20 pound cylinders.  Additional safety equipment on site includes a ton container cradle device which allows ton containers to be rotated in place to assist in inspection and repair if ever needed.   
 
The facility produces no hazardous wastes.  Every chemical by-product from the transfer process is reclaimed and used in swimming pool water treatment allowing no environmental wastes.  This business eliminates our customers' need to buy, transport, handle, and dispose of hazardous materials required for swimming pool water treatment. This provides a major benefit to the environment.   
 
No firefighters, police, or emergency response personnel have ever had to respon 
d to a hazardous material release from this facility.  No firefighters, police, or emergency response personnel have ever been injured or hospitalized from a chlorine release from this facility or on the job site. 
 
 
FIVE YEAR ACCIDENT HISTORY 
 
There have been no reported released of chlorine at this facility over the last five years (June 1994 through June 1999).  In addition, there have been no releases of chlorine at this facility since it began operations in 1984. 
 
 
EMERGENCY RESPONSE PROGRAM 
 
Splash Pool Chemicals of Arizona, Inc. has an Emergency Action Plan that is coordinated with the Rural Metro Fire Department.  This plan outlines the personnel to contact in the event of a release.  The facility plans to contact 9-1-1 in the event of a chlorine release and evacuate all employees. 
 
PLANNED CHANGES TO IMPROVE SAFETY 
 
A complete Process Hazard Analysis was recently completed at the facility to identify potential safety issues.  In addition, the existing Process Safety Management 
programs and procedures were reviewed in May 1999. The facility has worked to address safety issues as they arise in a continued effort to ensure a safe work environment.  The management is planning to continue with this program as follows: 
 
1.  Continued maintenance program for chlorine transfer equipment to ensure ongoing integrity. 
 
2.  Continue to train all employees in the Process Safety Management programs and procedures. 
 
3.   Continue to train employees in the safe handling of chlorine. 
 
4.   Review existing operating procedures and update as necessary.
