BGMU Wastewater Treatment Plant - Executive Summary
OVERVIEW OF BGMU SAFETY PROGRAM |
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.
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
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.
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.
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.
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.
Bowling Green Municipal Utilities (BGMU) is a combined
public utility. The accompanying organizational chart
illustrates the general structure of BGMU's Water-Sewer
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. Additionally, an estimated
39,000 persons are served via master meters (Western
Kentucky University and Warren County Water District).
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
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.

Chlorine is used, on a regular basis, at Bowling Green
Municipal Utilities' Water and Wastewater Treatment Plants.
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
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.
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
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
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
then contact the Chief Operator and
standby Maintenance personnel after 911 is
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
3. Large leak or spill -- Response by Bowling Green Fire
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
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
Flexible connector lines, manifold assembly or feed
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)
a. Contact the Bowling Green Fire Department by
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
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

1. 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
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
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
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.
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
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
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
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
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
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!!
A. Be cautious, do not become a casualty
B. Prompt treatment is essential. Firmness and
assurance to exposed persons will assist in
C. Immediately remove exposed person to an
D. Remove any contaminated clothing and wash
contaminated parts of the body.
E. Never give anything by mouth to an
F. Call 911 and obtain medical assistance.
Chlorine Gas Inhalation
A. When Breathing has Ceased.
1. Commence artificial respiration
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
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
C. Apply no greases unless ordered by a
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 combines with water
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 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
PROFESSIONAL MEDICAL ATTENTION IS MANDATORY.
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
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
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
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
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
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
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
As stated in the Bowling Green Municipal
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.

contained herein are limited to the requirements for
emergency response at other than hazardous waste clean-up
(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.
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
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
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.
