CIty of Jacksonville Beach Water Plant No. 1 - Executive Summary

| Accident History | Chemicals | Emergency Response | Registration | Source | Executive Summary |

The City of Jacksonville Beach Water Treatment Plant Number One (Facility) is a water supply 
facility (NAICS Code 22131) for the city of Jacksonville Beach, using one regulated substance, 
chlorine (CAS Number 7782-50-5), in the chlorination process.  The chlorination process consists 
of the use of chlorine from one-ton cylinders to treat potable water in a standard chlorine disinfection 
The hazard assessment was performed on the chlorination process using the United States 
Environmental Protection Agency (USEPA) RMP*CompTM Model.  The worst-case release scenario 
was assumed to be the release of a one ton cylinder over a 10 minute period.  The alternative release 
scenario selected for the Facility was a failure scenario developed during the process hazard review 
and analysis.  In this scenario, a 0.25-inch diameter orifice is formed in a one-ton cylinder as the 
sult of a poor bond between the lead alloy and the fusible plug retainer.  The Facility has the 
capability of responding to and stopping the leak within 30 minutes of detection.  For both scenarios, 
the off-site consequence analysis indicated that off-site receptors could be potentially impacted by 
the release of chlorine.  Although off-site areas would be impacted, the Facility believes that safety 
procedures and mitigation measures will reduce the potential for off-site consequences and 
subsequent risks to the surrounding community.  The Facility's safety devices include chlorine leak 
detectors, alarms, and an automatic system shut-off feature triggered by a loss in system vacuum.  
In order to fulfill the requirements of the Risk Management Program (RMP), the Facility has 
developed an accidental release prevention program and emergency action plan for the Facility. The 
accidental release prevention program satisfies the requirements for the USEPA RMP and the 
Occupational Safety and  
Health Administration's (OSHA) Process Safety Management (PSM) 
program.  The prevention program ensures that the Facility is operated under safe conditions and that 
any risk of an accidental release of chlorine is minimized.  The program has been written to reduce 
the potential of an accidental release due to human error, or equipment failure at the Facility.  In 
order to help prevent the release of chlorine due to human error, the Facility's prevention program 
ensures that operating procedures are current and reviewed annually.  Training also plays a vital part 
in the Facility's program.  Employees and contractors working near or on the chlorination process 
are required to be trained in the chlorination process and the hazards of chlorine.    
To prevent equipment failure that could result in a release, the program ensures that equipment 
inspections, tests, and preventive maintenance are performed in accordance with accepted 
engineering practices, manufacturer's recommendations, and p 
lanned maintenance schedules.  All 
chlorine cylinders are examined upon delivery and are rejected if there are any signs of damage.  In 
addition, equipment pertaining to the chlorine process is visually inspected daily.  The potential for 
a chlorine release is greatly reduced in the chlorination process due to the use of a vacuum system 
from the point of chlorine withdrawal to its point of application.  In the event that there is a failure 
in chlorination equipment, the system will automatically shut down (i.e. failsafe).   
All existing and proposed future chlorination equipment have been designed according to applicable 
standards and codes.  The Facility maintains records and documentation on equipment inspection 
and tests.  Precautions are taken to ensure that new equipment and processes are inspected and tested, 
that all changes on the process are authorized, and employees are informed of changes. 
The Facility performed a Process Hazard Analysis (PHA) to address the hazards in the 
process and to evaluate and control where the potential for a chlorine release exists.  Employees were 
involved in determining hazards of the process and subsequent consequences.  The chlorination 
process was found to be operating safely and no changes were recommended.  
Active employee participation will ensure the success of the RMP at the Facility.  Employees have 
been assigned various tasks to ensure that all elements of the RMP are implemented.  The Facility 
has developed management forms to assist employees in recording and documenting the various 
elements of the RMP.  
At the time of the submittal of this Risk Management Plan, there have been no accidental releases 
of chlorine at the Facility in the past five years.  However, in the event that there is an accidental 
release of chlorine, an Emergency Action Plan has been written in compliance with 29 CFR 1910.38.  
The Facility is also included in the community emergency response plan.  Employees at the Facility 

o not respond to accidental releases of chlorine, but coordinate with outside responders.  Therefore, 
an Emergency Response Program is not required for the Facility.  In the event that a chlorine release 
occurs, all employees are required to evacuate the process area and report the incident.  The 
emergency action plan consists of evacuation procedures, facility emergency numbers, and 
coordination with the City of Jacksonville Beach Fire Department.  The plan also addresses 
notification procedures to the public and the local emergency response agency.
