Date: 6-15-99 Executive Summary for Risk Management Program for Kitsap County Public Works Central Kitsap Treatment Plant *The Central Kitsap Treatment plant is located at 12350 Brownsville Highway, Poulsbo, WA. This Wastewater Treatment plant is rated at 6 million gallons per Day with an average daily flow of 3.6 million gallons per day. This Treatment plant is a secondary activated sludge plant with anaerobic sludge digestion. The area served by this Treatment plant includes the City of Poulsbo, town of Silverdale, Bangor and Keyport Military bases and the surrounding areas. One ton chlorine cylinders are used as an odor control agent for the incoming wastewater streams. One ton and 150 # cylinders of chlorine are stored at the Central Kitsap Tr. Plant for use at outlying Kitsap County Public Works lift station and treatment plants. During normal operations a total of four full one ton cylinders with one cylinder on lin e and three as spares may be present. Up to fifteen one hundred and fifty # cylinders which are stored but are not used at the Central Kitsap Tr. Plant, may be present at any one time. These cylinders are used at offsite stations. The accidental release prevention and emergency response policies available to the employees at the Central Kitsap Treatment plant include: Related Policies contained in the Kitsap County Public Works Safety Manual, Revised 10 -98. After Normal Working Hours Duty List - Standard Operating Procedures. Chlorine Leaks - Standard Operating Procedures Lock out- Tag out, The Policy Confined Space, The Policy Respiratory Protection, The Policy All these documents are written at the direction of Randy Casteel, Director of Public Works. Chemical Hazard Communications Includes Department of Labor and Industries Guidelines WAC 296-62-054 through WAC 296-62-05425. *The Worst Case Scenarios for the Central Kitsap Treatment Plant This would be a chlorine gas release f rom the chlorine building located on the Central Kitsap Treatment Plant grounds. This would be a gas release after midnight, when there is no one on the plant grounds. The chlorine leak detector senses a chlorine leak and the auto dailer calls out the on call personnel. During this time that it takes for the on call personnel to arrive, which is approximately 10 to 20 minutes, the public which is down wind in the south direction has called the fire department with a complaint of a smell of chlorine in the air. On call personnel will work with fire department personnel and the local emergency response personnel to alert down wind residents which are located in the down wind quadrant using the program designed by the Kitsap County Public Works personnel. State patrol and the fire department personnel will monitor roads and control traffic in the area. Areas affected would mainly be residential, some recreational areas and small businesses due to the time of night. Worst case scenarios for Central Kitsap Tr. Plant gas release are reduced by checking chlorine tanks, gas piping and detectors and telemetry twice a day. The chlorine and telemetry equipment is on a data base monitored by a periodic maintenance program. Personnel use this program which takes the manufacturers' maintenance recommendations for a piece of equipment and use the information to perform maintenance in a timely fashion. The chlorine cylinders are checked by the chlorine supply company on a regular basis. 7 The alternative scenario for the Central Kitsap Tr. Plan The Central Kitsap Tr. Plant is manned 24 hours a day during the winter months (October through March). The Late night maintenance worker receives an alarm from the chlorine leak detector, calls for on site help from the on call personnel. Maintenance personnel does not smell chlorine from outside the chlorine building, waits for assistance to arrive. Kitsap County personnel following standard operating procedures for a response to a ch lorine leak, enter the chlorine building , determine the problem and correct a piping problem stopping the chlorine leak. Problem was corrected by securing the chlorine cylinder and leaving it off line until a maintenance crew can restore the system to normal operation. * The General accidental release prevention program and chemical - specific prevention steps The Central Kitsap Tr. Plant personnel will be guided by the OSHA - PSM rule and the DOT P 5800.5 Emergency Response Guidebook, Kitsap County Public Works' Safety manual, standard operating procedures and Washington state Department of Labor and Industry WAC's l in their daily activities. Improved documentation and new computer programs like the Chlorine initial isolation and protective action program, will improve safety and respose time. 7 The Five Year accident history There have been no accidental releases of chlorine in the last five years for the central Kitsap Tr. Plant. * The Emergency Response Pr ogram for Central Kitsap Tr. Plant and Central Kitsap Fire and Rescue Kitsap County personnel have met with the Central Fire and Rescue Chief for the town of Silverdale and Fire Dist. 1 to further develop an emergency response and responder capability program . The fire department will take an active role to alert the public during an actual event. Tools provided by Kitsap County. Map: Chlorine : Initial Isolation and Protective Action Distances Demonstrates both large and small spill protective action distances, eight directional quadrants are used to map population and wind direction. Reports: Chlorine Response Report Provides notification information for a spill in a given quadrant (s). Useful information is population counts, name, address and phone number of potential persons to evacuate. Training: Monthly meetings will be scheduled to include training and information sessions with the fire department and LEPC. Kitsap County Public Works will continue emergency response a nd chlorine training with its employees and local fire department personnel. Drills: Kitsap County Public Works and local emergency personnel will plan and conduct emergency response to a chlorine leak including simulated public notification and traffic control. Public notification: Kitsap County Public Works will work with the local emergency planning committee to determine a course of action to notify the public. 7 Planned changes to improve safety June 29,1999, Meeting with Fire Department to demonstrate Chlorine isolation and response program. July 6,7, 1999 will be Confined Space and Respiratory protection training August 18, 19, 20, 1999 will be Confined Space and Rescue The year 2000 will bring about the conversion of gaseous chlorine to Sodium Hypochloride will bring the hazard level for chlorine disinfection down. Chlorine gas will no longer be stored at the Central Kitsap Tr. Plant. |
