BGMU Wastewater Treatment Plant - Executive Summary |
OVERVIEW OF BGMU SAFETY PROGRAM PERSONNEL Bowling Green Municipal Utilities employees a full time Safety Director and two part-time Safety Officers. The Safety Director is responsible for the overall development, administration and supervision of activities required by OSHA, EPA, DOT and other federal and state agencies, to safeguard all BGMU employees. There are Safety Officers at the Treatment Plants, with their primary job consisting in Plant Operations and then secondary as Safety, in which they coordinate all inspections, safety equipment and employee assistance in safety at the Treatment Plants. PROGRAM ADMINISTRATION Bowling Green Municipal Utilities on April 27, 1989 hired a full-time Safety Director so that BGMU could develop and implement a written Safety Program. With the hiring be completed, the major obstacle was achieving compliance in the OSHA, EPA and DO T regulations so that BGMU and all the employees would have a safe and healthful work environment. To this date the Safety Department now handles all of the compliance programs in the Electric, Water and Sewer Divisions, with the only exception being environmental issues that directly involve the Industrial Wastewater Pretreatment Program, which the Industrial Pretreatment Director handles. Bowling Green Municipal Utilities initialized a Safety Committee on October 26, 1994 starting with a member from each work area for a total of 10 members. This committee makes its recommendations for health and safety issues that include investigations of injuries/accidents. Bowling Green Municipal Utilities insures that each employee upon being hired is issued an employee handbook, in which this book explains many benefits, employment rules, insurance plans, work hours and policies. TRAINING Bowling Green Municipal Utilities Safety Department develops and conducts monthly safety meetings, which are coordinated with department supervisors, so that all employees can attend. The safety meetings that are conducted with the employees range from Hazard Communication, Pole Top/Bucket Rescue, First Aid/CPR to Confined Space training. A complete list of monthly training is sent to each System Manager three months prior to the beginning of the new year. The training for each employee is recorded and filed. Bowling Green Municipal Utilities also conducts training sessions with other agencies which include the local Fire Departments, Local Emergency Planning Committees, Emergency Medical Services, local Universities and other local Utilities. This training with these agencies proves that BGMU has a good community service orientated background for safety training. These ses sions include but are not limited to Electrical Safety, Hazardous Materials, Confined Spaces, Inspections, etc. EQUIPMENT Bowling Green Municipal Utilities has established a policy to ensure that the employees and their workplace are in a safe and healthful work environment. BGMU is committed to each employee by providing the employee with certain safety equipment, with a brief list of: safety glasses, hard hats, rain gear, hearing protection, respiratory protection, fall arresting equipment, etc. The Safety Department is constantly reviewing each job function (Hazard Assessment), to ensure that all aspects of health and safety are being provided to BGMU employees. REPORTING INJURIES Bowling Green Municipal Utilities is committed to employee health and safety, but due to working conditions that sometimes cannot be controlled, accidents occur. If you should suf fer any work-related injury, no matter how minor, it shall be reported to your supervisor immediately. This injury should also be reported to the Safety Department so the appropriate accident reports can be filled out. GENERAL OVERVIEW WATER-SEWER DIVISION Bowling Green Municipal Utilities (BGMU) is a combined public utility. The accompanying organizational chart illustrates the general structure of BGMU's Water-Sewer D ivision. The Water-Sewer Division in the event of a crisis specifically writes this Emergency Response Plan for use. BGMU's Water Treatment Plant serves the potable water supply needs of the city of Bowling Green, KY and a large portion of Warren County, KY. BGMU has over 15,600 water service connections serving the approximation of 54,000 persons within the city limits.

The Water Treatment Plant is located north of downtown Bowling Green, KY at 16 Chestnut Street. BGMU uses the Big Barren River as their raw water source. BGMU's Water Treatment Plant provides flocculation, sedimentation, disinfection, filtration and fluoridation processes for a capacity of 22.5 mgd. The finished product is pumped from the clearwells to the distribution system. The average flow per year is 14.5 mgd. The distribution system con sists of over three hundred (320) miles of water mains, over 1900 fire hydrants, thousands of valves, four (4) pumping stations and four (4) above ground level storage tanks which totals eight (8) million gallons of water. The distribution system is designed to provide adequate flow for domestic, industrial and fire fighting needs. The average household uses an estimated 200 gallons a day. BGMU's WasteWater Treatment Plant serves the sanitary and industrial sewage treatment needs of the city of Bowling Green, KY as well as portions of Warren County, KY. BGMU has over 15,600 sewer service connections serving approximately 50,000 persons within the city limits. With various industries, Western Kentucky University, and those portions of Warren County that has the service accounts for another estimated 27,000 persons. The Waste Water Treatment Plant is located northeast of downtown Bowling Green, KY at 1189 Preston Street, adjacent to Hobson Grove Park a nd Golf Course. BGMU's Wastewater Treatment Plant utilizes an aerobic digestion and activated sludge process. Discharge is to the Big Barren River, flowing approximately 800 feet to the rear of the facility. The average daily flow through the facility is 7.0 million gallons. The wastewater collection system consists of approximately 190 miles or 996,740 feet of gravity sewer 14 miles or 73,444 feet of force mains, 54 sewer lift stations and approximately 4,700 manholes. The Water-Sewer Division has approximately 63 employees with varied and numerous skills. Many of the supervisors and all stand-by employees have radio-equipped vehicles and/or a portable radio with them at all times. On a rotating basis, crews, and supervisors are "subject to call" for services needed after hours. In the event of a major emergency that involves loss of telephone or power radio communications, designated employees have been instructed to report to the normal work area for assignment in the emergency response activities. The following Emergency Response Plan is designated to provide detailed resources information to those responding to emergency conditions. It does not give extensive details on exact responses to specific events. Individual events have infinite variability and plans that are too specific may be useless in response to the event. The Emergency Response Plan will serve as a list of available resources/information and contain general instructions related to selected emergency events. 04/1/99 GENERAL OVERVIEW ELECTRIC DIVISION Bowling Green Municipal Utilities (BGMU) is a combined public utility.

The Commonwealth of Kentucky mandates the use of chlorine in Public Water Supplies. Chlorine is used as a primary and secondary disinfectant at the water treatment plant. It is used as the primary disinfectant at the wastewater treatment plant. The average amount of chlorine used is 372 pounds per day at the water treatment plant and 270 pounds per day at the wastewater treatment plant. The feed systems consist of five (5) W & T V-Notch type chlorinators at the water treatment plant and two (2) W & T V-Notch chlorinators at the wastewater treatment plant. During normal operation, six (6) cylinders (1 ton each) are connected in parallel to the manifold system at the water treatment plant with two (2) cylinders (1 ton each) connected at the wastewater treatment plant. The manifolds are a split type with automatic switchover systems allowing selected amounts of cylinders to be used at a given time. Storage room capacity at the water treatment is nine (1 ton cylinders) and six (1 ton cylinders) at the wastewater treatment plant. Normal operation would be three (3) cylinders in service with three (3) cylinders ready to switch over for use at the water treatment plant. Normal operation at the wastewater treatment plant would be two (2) cylinders in service with four (4) cylinders in storage. All s tored cylinders are mounted on cradles, at floor level, at both facilities. Within this section are schematics of the chlorine feed and storage areas for both treatment facilities. Additionally, equipment information, "Kit B" emergency repair kit location, and MSDS data and chlorine handline information are included. CHLORINE LEAK RESPONSE PROCEDURES Personnel on duty shall assess the severity of any leak! A. Maintenance and/or the operator(s), that will handle loading or unloading of cylinders, shall perform this function by a group of 2 or more individuals using the buddy system with proper communications. 1. Communications shall be maintained at all times during the loading/unloading of cylinders, or when responding to a leak by means of radio communications, by the operators to the Safety person standing by. 2. The Safety person standing by shall verify m onitoring. 3. SCBA's shall be worn during any maintenance or leak response by the maintenance technicians, operators, or by observers. B. Less than 1.0 ppm atmospheric chlorine concentration. NOTE: Fixed alarm system will alarm at a minimum concentration of 1 ppm or greater. C. All personnel or persons will evacuate the area immediately to don SCBA's and start portable monitoring (see attached "Portable Monitoring Procedures"). 1. If concentration is 3.0 ppm or below, personnel may assess severity/source of leak and attempt repairs, if possible. If there is only one operator on duty, then that operator will don SCBA and take the Chlorine meter (turned on and functioning) and proceed to the chlorine room to determine if it is a false alarm or an actual leak. If it is a leak then contact the Chief Operator and standby Maintenance personnel after 911 is called. Classifications of leak responses 1. Small leak or spill -- Response by personnel on site. a. Examples of small leak -- loose packing gland, valve intact but not seating properly, pin-hole leaks in manifolds, connector lines or feed equipment in which the amount of leakage has not created an environment in which can not be controlled for proper response and corrective actions by means of shutting down supply, and ventilating area until area is deemed safe. 2. If there is only one operator on duty and the concentration of 3.0 ppm to 10 ppm is read at the door then the operator shall contact the Chief Operator and the on-call maintenance personnel by either the phone or by contacti ng the treatment plant by radio to make the call for those person(s). DO NOT MAKE ENTRY BY YOURSELF BUT KEEP MONITORING. IF THE CONCENTRATION GOES ABOVE 10ppm THEN MAKE THE CALL TO THE FIRE DEPARTMENT FIRST!! 3. Large leak or spill -- Response by Bowling Green Fire Department. a. Any leak in the chlorine storage containers, piping or feed systems that can not be controlled by shutting down supply, and ventilating the area in which an amount of chlorine at 10 ppm or greater. NOTE: Large leaks and/or spills require calling 911 for Bowling Green Fire Department! SMALL LEAKS OR SPILLS Cylinder valve packing gland is discharging, outlet leaks: a. Closing the valve or tightening the packing gland nut can often stop leaks around valve stems. Tighten the nut or stem clockwise. b. Replacing the gasket or adapter connection can often stop leaks at the valve discharge outlet. Flexible connector lines, manifold assembly or feed equipment leaks: a. Shut cylinder discharge valve immediately and draw-off gas within the equipment by means of vacuum operated chlorinators. LARGE LEAKS OR SPILLS (FOR HAZMAT RESPONSE TEAM) One-ton container a. Contact the Bowling Green Fire Department by calling 911. b. Contact the appropriate internal personnel. c. Contact the Safety Department. d. When leakage is stopped notify manufacturer and DO NOT MOVE OR REMOVE CYLINDERS. e. Monitor cylinder until properly removed from facility site. f. DO NOT SPRAY WATER ON ANY CHLORINE LEAK. Water will react with chlorine to form hydrochloric acid thereby increasing corrosion of the cy linder and equipment. g. Absorption Systems -- a simple absorption system consists of a suitable tank capable of holding the required alkaline solution. The alkali should be stored in a form such that a solution can readily be prepared when needed. After the solution is prepared, the chlorine can be passed from the container into it through a connection weighted to hold the outlet under the surface; do not immerse the container. CAUTION: When absorbing chlorine in alkaline solutions, the heat of reaction is substantial. Caustic solutions can cause burns to personnel.

When cylinders are in the proper position with valves lined-up vertically, upper valve will provide "gas" for use and lower valve will provide liquid chlorine. Normal chlorination at BGMU is accomplished utilizing chlorine "gas". 2. During shipment, occasionally liquid chlorine will be trapped in the upper education port or piping within the cylinder. For this purpose, heaters are installed on the chlorine manifold for the purpose of evaporating such liquid amounts. Heaters must be operational at all times. STANDARD FUSIBLE PLUG FOR TON CONTAINERS Fusible Plugs 1. All ton containers are equipped with fusible metal pressure relief devices. Most have 6 (six) fusible metal plugs, three in each end, spaced 1200 apart. The fusible metal is designed to yield or melt between 1580F and 1650F(700C & 740C) to relieve pressure and prevent rupture of the container in case of fire or other exposure to high temperature. Types of Leaks or Release A. Continuous Release -- chlorine can be rele ased from a point source over a period of time. An example of such a release is a leak through a faulty flanged joint. Such a leak will get worse until the condition is corrected. Until that time the down-wind hazards will continue. B. Slug Release -- a slug release will occur if a vessel incurs a large puncture or ruptures. Large quantities of chlorine will be discharged in a short time. In the case of a puncture in the upper (vapor) portion of the vessel about one-fourth of the liquid (depending on the liquid temperature) will rapidly evaporate or "flash off". This will cool the remaining liquid to the atmospheric boiling point. The evaporation rate of the remaining liquid primarily depends on the heat input from the atmosphere. In the case of a puncture in the liquid phase, liquid will be expelled through the hole until the liquid drops to the lip of the opening. Most of the liquid expelled will "flash off" as it comes out of the tank, but some may spill on the ground. The evaporation rate of the spilled liquid depends on heat input from the ground and from the sun. Reducing the surface area of the spill will reduce the evaporation rate. The addition of water streams will provide additional heat and will increase the evaporation rate. Area Affected Mathematical modeling has been done to estimate the dispersion characteristics of chlorine gas cloud from a release. The area and exposure duration depend upon the total quantity released, the rate of release, the h eight of the release point, and weather conditions. These factors are difficult to evaluate in an emergency situation. Chlorine downwind can vary from barely detectable to high concentrations. Effect of Chlorine on the Environment A. Vegetation - chlorine causes bleached spots on leafy plants due to attack on chlorophyll in the leaf. Mature leaves are most susceptible to chlorine injury. Usually the plant itself is not destroyed although yield or growth rate may be retarded. B Animals - The U.S. National Institute for Occupational Safety and Health 1980 "Registry of Toxic Effects of Chemical Substances" lists the following inhalation LC50's (concentration of chlorine in air lethal to 50% of the defined animal, exposed over the specified time pe riod): Human ---840ppm/30 minutes Rat --- 293ppm/60 minutes Mouse --- 137ppm/60 minutes For an unspecified species of mammal the lowest concentration of chlorine in air (other than LC50) which has been reported to cause death in humans or animals is listed as 500ppm/5 minutes. C. Aquatic Life -- Chlorine is only slightly soluble in water and there would be little absorption from a cloud of chlorine gas. Many forms of aquatic life are adversely affected by chlorine in concentrations well below 0.1 ppm but harmful concentrations are unlikely unless chlorine is discharged directly into water. DISPOSAL OF CHLORINE REMAINING IN CONTAINER The stopping of leaks by the emergency devices is only an interim measure; the ton con tainer must be emptied as soon as possible. Chlorine may be passed into and absorbed by a solution of caustic soda or soda ash. Each 100 pounds of chlorine to be absorbed requires either at least 125 pounds of caustic soda dissolved in about 42 gallons of water or 300 pounds of soda ash dissolved in about 100 gallons of water. If the chlorine cannot be consumed or absorbed, the capped or plugged container should be removed to a remote area. Consult with the chlorine supplier immediately & arrange for ultimate disposal. CHLORINE KIT B LIMITATIONS Some ton containers in current use are of such design that application of kit "B" devices might be difficult or impossible. Among these are included those containers with double-dished heads; with fusible plugs located too close to valve protection hood lugs (precluding proper placement of device 4); with valve protection hood fastened by means of a single stud located be tween the two operating valves (precluding use of device 12); and, with over-sized valve bushing (precluding proper seating of gasket 4-12BMV, 12 BBV or 12MV and of hood assembly 12A.) Kit "B" devices also are unsuitable for stopping leaks around the chime of ton containers. FIRST AID FOR CHLORINE EXPOSURE ALWAYS CALL 911 FOR SOMEONE THAT HAS EXPOSED TO CHLORINE!! General A. Be cautious, do not become a casualty yourself. B. Prompt treatment is essential. Firmness and assurance to exposed persons will assist in alleviating anxiety. C. Immediately remove exposed person to an uncontaminated area. D. Remove any contaminated clothing and wash contaminated parts of the body. E. Never give anything by mouth to an unconscious person. F. Call 911 and obtain medical assistance. Chlorine Gas Inhalation A. When Breathing has Ceased. 1. Commence artificial respiration immediately. 2. Administer oxygen as soon as possible. The SCBA will be sufficient enough until the ambulance gets to the plant. B. If Breathing has not Ceased. 1. Place patient in a comfortable position. 2. Administer oxygen as soon as possible. The SCBA will be sufficient enough until the ambulance gets to the plant. 3. Keep patient warm and at rest. 4. Render any other necessary first aid. Liquid Chlorine Eye Contact A. Flush eyes immediately with copious amounts of running water for 15 (fifteen) minutes. B. Forcibly hold eyelids apart to ensure complete irrigation of eye and lid tissues. C. Do not attempt chemical neutralization of any kind. Liquid Chlorine Skin Contact A. Place pers on in the emergency shower, removing clothes in shower. B. Wash well with copious amounts of soap and water. C. Apply no greases unless ordered by a physician. PROTECTIVE CLOTHING General A. Protection from chlorine gas must be provided first of all for the respiratory system followed closely by protection for the eyes. This normally takes the form of a full-face mask with a positive pressure air system. B. SCBA's are required for any routine maintenance, connecting or disconnecting cylinders and loading/unloading or cylinders. C. Protection for the rest of the body is available (Tyvex suits) if personnel determines it is necessary and if the concentration is above 10ppm then the Bowling Green Fire Department is called for Level A Suit entry. Gaseous Chlorine Gaseous chlorine combines with water (perspiration) to form a weak acid - hypochlorous acid. When chlorine gas dissolves in perspiration, the weak acid creates mild skin burns similar to those that might be created by strong vinegar. Such burns will become apparent most quickly in the sensitive areas of the body such as around the genitals, between the buttocks or under the arms. Protective clothing should reduce exposure of all body surfaces to chlorine gas so as to minimize the physiological damage that may occur. It must be recognized that a given concentration of chlorine gas will be more harmful in a hot, moist climate than in a cold, dry climate. Similarly, it will be more harmful to a person who is working hard in such an atmosphere than it will to a person who is quickly passing through an area. Liquid Chlorine Liquid chlorine is a very cold liquid, boiling at -34F (-29C). Contact with such a liquid will result in frostbite. The only protection is to remain out of the range of the liquid. Protective clothing, which will prevent penetration of chlorine gas, is unlikely to be insulated on the inside and will be ineffective against frostbite. After Exposure to Chlorine Personnel should shower immediately after being exposed to high concentrations of chlorine so as to wash away the harmful substances and minimize physiological damage. PROFESSIONAL MEDICAL ATTENTION IS MANDATORY. General A. Protective clothing is for the protection of rescue, emergency repair crews and it may be required for the protection of personnel making routine or scheduled repairs. It should never be required under routine operating conditions. When an emergency occurs, the personnel directly involved must escape from the hazardous a rea quickly with special protective clothing. SCBA's are always in use. B. Once a chlorine leak has occurred a decision will be made with the Bowling Green Fire Department to decide which type of protection will minimize the hazardous consequences of delay in controlling the leak. PERSONAL PROTECTIVE EQUIPMENT Location of Personal Protective Equipment (PPE) A. Self Contained Breathing Apparatus (SCBA) 1. In a chlorine-contaminated environment a self-contained breathing apparatus (SCBA) shall be used; but only by trained personnel. Three complete units are located in the Water Treatment Plant and the Wastewater Treatment Plant in areas designated, with spare cylinders also available. Additional SCBA's are available if request ed. C. Chlorine Repair Kits 1. A Kit B Chlorine Repair Kit is available at the BGMU Water Treatment Plant facility, which is located in the chlorine storage area. 2. A Kit B Chlorine Repair Kit is also available at the BGMU Wastewater Treatment Plant facility, which is located in the chlorine storage area. D. Portable Chlorine Monitors 1. There are Three (3) portable chlorine monitors that are available and shall be used as required. One of which is located in the operator's office of the Water Treatment Plant, the other is located in the operator's office of the Wastewater Treatment Plant and the other is at the Water Sewer Crew Quarters Building. SUMMARY AND CONCLUSIONS When a chlorine lea k occurs, each case must be handled on its own merits. Decisions must be made which will minimize the amount of chlorine that is released while at the same time having others provide warning or rescue to persons who are in danger. Normal work clothing will provide all the protection that is required for the period of time it takes to escape from an emergency. Such clothing, in combination with SCBA respiratory equipment, can be satisfactory for very brief periods required for rescue or valve closing. Extended exposure to chlorine gas will be handled by the Bowling Green Fire Department and their performance of essential duties will be performed by their Standard Operating Procedures which will be handled by their Incident Commander. Judgment must be used when high concentrations of chlorine gas or prolonged exposure is required or when persons may not have the option of moving out of the chlorine gas. When the maximum level of protections will have to be used, the Bowling Green Fire Department will make that determination. They have been specifically trained in the use and limitations of such equipment. HAZ MAT ACTIVATION The activation of the Bowling Green Fire Department HAZMAT Team is necessary in the event of the release or spill of a hazardous material in quantities which result in contaminant levels reaching a point where Level A personal protective equipment (PPE) must be used, and the chlorine meter reads 10ppm or greater at the door, and the leak cannot be controlled. It is the responsibility of the supervisor to determine when an emergency situation is, or has expanded to, a HAZMAT situation. As stated in the Bowling Green Municipal Utilities' overview, the Bowling Green Fire Department Hazardous Materials Team will be the primary response to a Chlorine Emergency, and shall have received the required training and have readily available to them all the P.P.E. necessary to safely handle a HAZMAT type emergency. BGMU will have persons designated as Hazardous Materials Advisors and ONLY they have been completely trained in HAZMAT and Chlorine Procedures and will respond and remain "on-site" of either treatment facility during such an event. It is highly probable that any HAZMAT response will involve CHLORINE, in either gas or liquid form. In either event, all person(s) should exit the facilities traveling toward exits opposite the wind direction. Wind direction can be determined by observing the bright orange windsocks located at both treatment facilities and then traveling to designated response locations. If possible, SCBA's stored in the operator's area of the treatment facilitie s should be brought as you exit the facilities. There shall be NO RE-ENTRY to the facility until the supervisor has advised that all is clear. The following pages are outlines of the Chlorine HAZMAT program of the BGMU Water-Sewer Division: BOWLING GREEN MUNICIPAL UTILITIES WATER-SEWER DIVISION BOWLING GREEN, KENTUCKY HAZARDOUS MATERIAL RELEASE RESPONSE OVERVIEW - HAZMAT - 29 CFR 1910.120 NOTE: The explanations, definitions, and information contained herein are limited to the requirements for emergency response at other than hazardous waste clean-up sites. (1) APPLICATION (52 FR 29640) "HAZARDOUS MATERIALS (HAZMAT) TEAM" "Hazardous materials response (HAZMAT) team" means an organized group, designated by the employer, who are expected to perform work to handle and control actual or potential leaks or spills of hazardous substances requiring possible close approach to the substance. These team members perform responses to releases or potential releases of hazardous substances for the purpose of control or stabilization of the incident. A HAZMAT team is not a fire brigade nor is a typical fire brigade a HAZMAT team. A HAZMAT team, however, may be separate component of a fire brigade or fire department. The Haz-Mat Team that will be responding is the Bowling Green Fire Departments' Hazardous Materials Team, which will be responding on a Haz Mat Technician Level with an On Scene Incident Commander. First Responder Awareness Level shall be maintained by all BGMU Water-Sewer Division employees to which there will be also designated Haz Mat Advisors to respond with the Bowling Green Fire Department Hazardous Materials Team. The only employees that are not First Responder Awareness Level will be office and engineering personnel. ***ENVIRONMENTAL ACTIVITIES*** Treatment plant operator(s), when on duty, shall monitor and determine the severity of any leak or spill which could result in a hazardous/emergency incident. All leaks or spills shall be reported to the Chief Operator immediately, the other treatment plant and then to the Safety Department. The facilities are occupied and monitored 24 hours a day and 7 days a week. ***SAFETY/SECURITY*** It shall be the responsibility of the BGMU to insure safety at the site of the emergency with the help of the Bowling Green Fire Department Safety Officer, and BGMU's responsibility to insure total site security. BGMU Employees, will not be specifically assigned for HAZMAT, but may be utilized as needed for security purpo ses after non-contaminated areas have been established. The facility is fully enclosed with fencing; all exits are secured from 5:00 p.m. to 6:00 a.m. weekdays. Facility exits/entrances are secured at all times on weekends. ***RESERVE TECHNICAL GROUP *** MEDICAL: Medical Center Ambulance Services Medical Center of Bowling Green 250 Park Street 250 Park Street Bowling Green, Kentucky 42101 Bowling Green, Kentucky 42101 Phone: 745-5000 or 843-5000 or 911 Emergency Room: 745-1005/745-1004 Contact: Randy Fathbuckner Contact: Mary Kovar (ext. 1863) Greenview Hospital of Bowling Green 1801 Ashley Circle Bowling Green, Kentucky 42101 Phone: 781-4330 Contact: Carletta Priddy ENGINEERING: BGMU staff engineers are available as needed as well as beyond BGMU'S staff.
