1.Recording the Report of Possible Sanitary Sewer Overflow(SSO)
Generally,telephone calls from the public reporting possible sewer overflows/basement back
ups are received at the Old Fort Town Hall.
For phone calls reporting overflows and back ups,the Town Hall staff obtains all relevant
information available regarding the overflow including:
a.Time and date of the call;
b. Specific location of the overflow;
56

c. Description of problem(e.g.,what is overflowing,extent of spill, if the cause is obvious,
etc.);
d. Time possible overflow was noticed by the caller;
e. Caller's name and phone number;
f. Observations of the caller(e.g.,odor,duration,back or front of property); and
g. Other relevant information that will enable the Maintenance Dept to quickly locate,assess
and stop the overflow.
This information is recorded in the Sewer Complaint log and the Town Hall staff notifies the
Maintenance Dept and Collection System ORC. See more detailed procedures in Sections 4
through 6,below.
2.Confirming Overflows
A Maintenance Dept sewer response crew is dispatched by the Supervisor to confirm the
overflow(See Section 5,below).
3.Reporting Overflows
The Collection System ORC completes a Sewage Overflow Report within 24 hours of the sewer
overflow confirmation and provides the information by phone to the NCDENR/Water
Resources/Water Quality Section.(and see Section 6).
2. INTRODUCTION
Our collection system is an integral part of the Town of Old Fort's unseen infrastructure,taking
sanitary wastes from residences,commercial establishments and industry to the Old Fort WWTP
on East Main St.If the capacity of the collection system is exceeded,or if blockages occur,
overflows may result.Untreated wastewater overflows that occur upstream of the treatment plant
are called Sanitary Sewer Overflows(SSOs). SSOs are a threat to public health and the
environment because the SSO may discharge pollutants such as pathogens, floatable materials,
toxics,and other pollutants,all of which may impact public health,drinking water supplies,
water quality and/or aquatic ecosystems.
2.1 Goals
The goal of this Sewer Overflow Response Plan(SORP)is to document the Town of Old Fort's
plans for mitigating or preventing potential emergency overflows whenever possible,to prepare
the Town's personnel and responding departments to deal efficiently with the effects of such
events, and to protect health, environment,and property.
Quick response to an SSO will minimise the overflow impacts on public health,water quality,
the environment,and customer service. This SORP is designed to ensure that appropriate crews
are immediately dispatched to all reported SSOs to stop the overflow as quickly as possible;to
minimize the effects of the overflow on public health and the environment;to minimize the
impact of the overflow on collection system operations;and to report the overflow to the
appropriate regulatory agencies,and to the public when warranted.The objectives of this plan
include controlling waste discharge and providing procedures for managing sanitary sewer
overflows,preventing harm to public health and the environment,and satisfying regulatory and
57

reporting requirements.
Additional objectives of the SORP are to:provide appropriate customer service,protect
collection system personnel and the wastewater treatment plant,protect all parts of the collection
system and wastewater treatment plant,and protect private and public property beyond the
collection and treatment facilities.
This plan will be updated as necessary to reflect any changes in staffing or notification
requirements, including contact numbers. It should and must be revised as insight and experience
dictate.
2.2 This SORP is organized into the following sections:
Overview (Description of Collection System)
Overflow Notification procedures
Response to Overflows
Overflow Reporting
3. OVERVIEW
This section provides a general description of the Town of Old Fort's collection system and
critical facilities. Response personnel must be familiar with the collection system and its
components to effectively execute the response procedures described in this plan. For further
details on the collection system,crews are directed to our Preventive Maintenance Plan(PMP).
The Town of Old Fort's wastewater collection system includes the following components:
approximately 48102 linear feet of sanitary sewers; 0 siphons; 0 linear feet of force main; and 0
pumping stations. The system is comprised of components ranging in age from 50—60 years to 1
—2 years. Materials include ductile iron,PVC,and terra cotta pipe.
Old Fort's collection system contains several critical facilities.Depending on the specific critical
facility, a sewer system failure could potentially impact drinking water supplies, parks or
playgrounds, basements and street flooding. Critical collection system facilities are described
later in this section.
3.1 Specific Known Vulnerabilities
Certain areas of Old Fort are known to be more vulnerable to system blockages and overflows
than others and require additional maintenance. These vulnerable areas include: the sewer lines
close to Mill Creek,high-density population areas.
Mill Creek flooding has been the cause of some problems in the past. Advanced weather
{ prediction is not always accurate and extreme precipitation can develop without adequate
warning.High intensity storm events can also impact areas in the Town that are located above
designated flood plains.
A review of past maintenance records and citizen complaints indicates that fats,oil and grease
(FOG)have consistently contributed to the occurrence of SSOs in many areas. Old Fort has
increased maintenance (as described in the PMP)in these areas in response to the problems
identified.
58

Specific response procedures vary according to the type of facility where the emergency is
occurring.Response procedures for each of the critical facilities identified in this section are
specified in Section 5.The emergency response procedures reflect the types of facilities and the
likely types of failures and vulnerabilities in our collection system.Notification response,
Section 4,below,provides the process and contacts for reporting sewer overflows.
4. OVERFLOW NOTIFICATION PROCEDURE
4.1 Overview
When an SSO or other collection system emergency occurs,a number of individuals must be
notified.Depending on the size and severity of the problem,different notifications are needed.
While minimum notification procedures are in place for all overflows,more specific notification
procedures are required for more severe overflows. For example,a small,contained overflow
with no impact to a water body or other sensitive area will have fewer notification requirements
than an overflow that has discharged into surface water.
4.2 Receipt of Information Regarding an SSO
An overflow may be detected by the Town of Old Fort employees or by others. The Maintenance
Dept is the primary department responsible for responding to SSOs.The Maintenance Dept is
responsible for acting based on received phone calls or reports of possible sewage overflow from
the wastewater collection system, and providing immediate response to investigate and/or correct
the problem.
Generally,telephone calls from the public reporting possible sewer overflows are received at the
Old Fort Town Hall.Information is collected and dispatched as described in Section 1,Response
Information.
The Maintenance Dept will confirm the overflow and implement measures to stop the overflow
as noted in our procedures in Section 5,below.
The Collection System ORC completes a Sewage Overflow Report within 24 hours of the sewer
overflow confirmation and provides the information by phone to the NCDENR/Water
Resources/Division of Water Quality(DWQ).A written report is submitted within 5 days per
DWQ requirements.
If the overflow results in a fish kill,the Collection System ORC shall notify the DWQ by phone
within two hours of becoming aware of the results of the fish kill.
The Collection System ORC is responsible for reviewing,updating and signing the final Sewage
Overflow Report. Sewage Overflow Reports,clean up information and other information
are kept in the WWTP office and reviewed annually.
5.RESPONSE TO OVERFLOWS
Response procedures provide guidance for the evaluation,mitigation and correction of the
conditions that are causing or contributing to an unpermitted discharge of untreated waste water.
The primary objectives of these emergency response procedures are to provide standard
protocols,minimize risk,and protect public health and the environment,
59

Emergency response procedures appropriate to the vulnerabilities, sensitive areas and critical
facilities identified for the Maintenance Dept have been developed. These procedures reflect best
management practice.
The Maintenance Dept Supervisor or acting supervisor dispatches sewer maintenance personnel
with appropriate equipment to confirm and contain the overflow,and determine the cause. Crews
and equipment are available to respond to any SSO locations. The Maintenance Dept currently
has 3 crew members One employee is always on-call during off duty hours.The Maintenance
Dept relies on radio and telephone communication to dispatch personnel to the scene of the
overflow.
While investigating emergencies the crew should maintain radio contact with Town Hall at all
times to keep them informed of the progress and any problem(s). Upon completing an
assignment,and before returning to the Yard,the crew should call Town Hall by radio for any
other assignment or update.
5.1 Preliminary Assessment
Upon arrival at the reported sewer overflow site,and based on observations,the sewer response
crew may require additional personnel,material,supplies,and equipment from the Maintenance
Dept shop.
In all cases,response crews report their findings,including possible damage to private and public
property,to the Supervisor immediately upon making their investigation.
The Collection System ORC will visit the site of the overflow, if possible,to ensure that
provisions of this overflow response plan are met. The Collection System ORC is responsible for
informing the DWQ of all SSOs within 24 hours of becoming aware of the release.
If hazardous substances are suspected in the overflow,personnel are to contact the Fire
Department via 911 immediately.
5.2 SSO General Equipment
The following items are available to response crews.These items are stored in Maintenance Dept
water truck and at Maintenance Dept shop. Personnel are responsible for ensuring supplies are
appropriate and in working order and are responsible for obtaining additional supplies as needed.

PROBLEM: Sewer Blockage or Back up into Basement
EMERGENCY PROCEDURES:
• Dispatcher refers to sewer maps for location and to determine critical facilities and sewer
sub-area to provide to dispatch crew.If the area of the complaint is served by a pump
station, check to confirm whether any alarms from the pump station have been received.
• Dispatch the crew immediately to the complainant address with details. Crew notifies
complainant/property owner(s)when they are on site.
• If the flow is questionable(not reasonable for the given service area)go to the upstream
manhole to visually compare flows.
• If the flow from both manholes is reasonable for the area,notify the property owners that
the problem is in their service lateral and to contact a plumber or sewer service contractor
to relieve the blockage as described under `Steps to be Taken By Property Owners
When Sewage Back-Up Is Determined to be Due to Blockage In Private Lateral
Connection'
• If the downstream manhole is full and there is a potential for overflow,immediately
begin the set up for pumping around the blockage(see"Overflowing Sewer Manhole"
procedure)
• Request additional manpower and equipment as needed(e.g. excavating crew,
bypass pumping equipment,etc.)
• Set up pump out equipment and hoses from the upstream manhole to the nearest
flowing manhole below the blockage.
• Continue checking manholes downstream until a dry manhole is found indicating a
blockage upstream.
• See"Overflowing Sewer Manhole"procedure for pumping around the blockage
while the line is repaired
• Use the necessary equipment to relieve the blockage,either by jet flushing or rodding.
• Notify supervisor and describe the blockage.The supervisor will notify the proper
authorities and agencies(See responsibility chart).
• Cordon off the area if ponding occurs on the street or easement(public or private).
• Collect as much of the sewage as possible,disinfect according to policy,notify
surrounding homes(superintendent notifies appropriate officials,as needed).
• If the blockage is in a public line,relieve the blockage,clean up the property owner's
basement as per policy on disinfecting. If blockage is determined to be in property
owner's lateral connection,direct property owner to call plumber to clear the line.
• Make out a report indicating the time of the call,a description of the problem,repair
work done,personnel present and equipment used.
• If sewage overflowed the collection system,file the DWQ Overflow Notification Log
and Overflow Report Form as required(see responsibilities chart).
NOTES:
1. When available,use collected debris to try to determine the cause of the blockage.
Confirm removal of all debris from the manhole.

Town of Old Fort Maintenance Department
STEPS TO BE TAKEN BY PROPERTY OWNERS WHEN
SEWAGE BACK-UP IS DETERMINED TO BE DUE TO BLOCKAGE IN PRIVATE
LATERAL CONNECTION
After the Collection System crew has checked the Town sewer for blockage and has found
that the public sewer is not blocked,they will notify the property owner. It is the Townof
Old Fort's policy that if the main sewer is clear then the property owner must hire a
licensed plumber,drain layer,or sewer cleaner to free any blockage,which might exist in
the private lateral. property owner is responsible to pay for this activity.
NOTE: PROPER RODDINGThe PROCEDURE GUIDELINE FOR PROPERTY OWNERS
TO CLEAR PRIVATE LATERAL SEWER CONNECTION
If the blockage is found in the portion of the sewer house connection located within private
property,the owner must hire a licensed contractor to perform the necessary repair work,under
inspection from the Maintenance Dept.
The Maintenance Dept requires proper rodding procedures. In cases where a property owner
needs to free a blockage within their lateral,the plumber must use a 4"cutter at the end of the
rod. If they can't break through the blockage,they will then start using smaller cutters back up
to 4". If the plumber relieves the blockage,they must then rod the house connection to the main
sewer line.
All repair work on the sewer house connection must be performed by a licensed contractor, and
will be inspected by the local Maintenance Dept personnel.
WARNINGS:
If the property owner,licensed plumber,drain layer or sewer cleaner does not call the
Maintenance Dept and request the public sewer line to be checked prior to rodding,the
Maintenance Dept will not assume liability if the problem is located in the public sewer line.
If there is a blockage,but no record of the house connection,the owner must prove where the
blockage is located. This can be done by excavation or electronic locator in the presence of an
inspector.

PROBLEM: Overflowing Sewer Manhole Resulting from Surcharged Trunk Sewer(No
backup into building)
EMERGENCY PROCEDURES:
• Dispatch the crew immediately to the problem location.
o Refer to sewer maps for location of sewers(private lands,flow patterns,
manholes, etc.) and determine if the area is served by a pump station before
responding to the call.
• Go to the location of the overflowing manhole to assess the immediate danger to public
health or the environment.
• Determine the location of the blockage by inspecting the downstream manholes until a
dry manhole is found.Immediately begin the set up for pumping around the blockage
o Request additional manpower and equipment as needed(e.g.excavating crew,
bypass pumping equipment,etc.)or to help with evaluating options for pumping
around the blockage.
o Set up pump out equipment and hoses from the upstream manhole to the nearest
flowing manhole below the blockage.
• Capture the blockage debris,if possible. Remove the debris from the manhole and assess
it to try to determine the cause of the blockage.
• Use the necessary equipment to relieve the blockage,either by jet flushing or rodding. If
it is imminent that the waste water will be released into wetlands,receiving waters or a
drinking water supply watershed,contact Asbury's Septic Tank Cleaning or KACE
Environmental and notify supervisor,who will call in extra crew and coordinate
emergency equipment. The supervisor will also notify the proper authorities and agencies
including the fire department to set up flotation booms across streams,brooks,etc.if
necessary.
• Gather and remove sewage related debris and organic matter from the affected area.
• If the wastewater is in the streets/roads(public or private),use sand bags or spill
absorbent booms to contain the waste water to minimize any impact to public health or
the environment.
• Sandbag nearby catch basin inlets or paved leak-offs to prevent the waste water from
entering the drainage system and causing potential contamination to the receiving waters.
• Cordon off the area if ponding occurs.
• Collect as much of the sewage as possible,disinfect according to policy,notify
surrounding homes(superintendent notifies appropriate officials,as.needed).
• If the waste water jeopardizes a playground or park,cordon off the entire area. Close the
park to the public until the issue has been remedied to the satisfaction of the local and
state boards of health and the local park superintendent.
• Complete a report indicating the time of the call, description of the problem,repair work
done,personnel present and equipment used.
• If sewage overflowed the collection system,file the DWQ Overflow Notification Log
and Overflow Report Form.

PROBLEM: Cavities and Depressions in Streets and Lawns
EMERGENCY PROCEDURES:
• When a call is received from the public,confirm the following:
1. That the problem area is in fact a cavity or depression and not a missing or low
manhole cover, gate box cover or catch basin grate.
2. The location of the reported cavity and the name and address of the party making
the call.
• If the caller indicates the problem is severe,extensive or obviously associated with the
sewer or water system,investigate and barricade the condition if it appears appropriate to
do so. Lights and barricades should be used if the situation is dangerous.Notify the water
company immediately to aid in the cause investigation.
• When checking a depression over a main sewer,it is important to check the main sewer
at both the upstream and downstream manholes adjacent to the depression to determine if
there is a restriction of flow. If there is a blockage,it may indicate a possible main sewer
break.
• If the cavity is a result of a sewer failure,refer to procedures for sewer main collapse and
repair as appropriate.
• If it has been determined that it is a cavity or depression the crew should notify the
NCDOT and any other relevant utilities.
• The crew leader should thoroughly document the nature and extent of the impacts
including the use of photographs and video footage where possible.
• Make out a report indicating the time of the call, a description of the problem, the repair
work done,personnel present and equipment used.
• If sewage overflowed the collection system,file DWQ Overflow Notification Log and
Overflow Report Form.

PROBLEM: Sewer Main Break/Collapse
EMERGENCY PROCEDURES:
• Dispatch a crew to location of break/collapse immediately while referring to the sewer
maps for location of sewers (private lands flow patterns, manholes, etc.) to determine
which critical facilities are in the area.
• Crew sets up signs,barricades, and/or barrels for traffic control and public safety,
rerouting traffic as necessary and deploying traffic control measures such as police or
flag person as needed.
• If it is a main line break, the Superintendent shall notify the appropriate authorities and
town officials immediately.
• Request additional manpower and equipment as needed based on initial damage
assessment(e.g. excavating crew, equipment to pump around the break,etc.)
• Pumping around the break from the upstream manhole to the downstream manhole may
be required. If necessary,set up bypass pumping equipment. If not necessary,prepare
for repairs while the pipe is flowing.
• Call in additional crews to set up flotation booms across streams,install sandbags,etc., as
necessary. Unless special conditions exist,pumping around the failed sewer main is a
priority before containing the overflow.
• Gather and remove sewage related debris and organic matter from the affected area.
• If the wastewater is in the streets/roads(public or private),use sand bags or spill
absorbent booms to contain the wastewater to minimize any impact to public health or the
environment.
• Sandbag nearby catch basin inlets or paved leak-offs to prevent the waste water from
entering the drainage system and causing potential contamination to the receiving waters.
• Cordon off the area if ponding occurs.
• Collect as much of the sewage as possible, disinfect according to policy,notify
surrounding homes(superintendent notifies appropriate officials, as needed).
• If the waste water jeopardi7ps a playground or park,cordon off the entire area. Close the
park to the public until the issue has been remedied to the satisfaction of the local and
state boards of health and the local park superintendent.
• Determine the location of the break/collapse and make any necessary repairs. Use repair
procedures consistent with policy. If the break is on the pipe length,then a repair can be
made with a wrap-around sleeve. If the break is at the bell,then a bell joint clamp may
be used.
• Upon confirmation of adequacy of the repair,backfill the excavation(if necessary)and
restore surface conditions to match existing conditions.
• To restore the sewer line to full capacity, the crew should remove any debris that may
have entered and accumulated in the sewer line downstream and upstream from the
break/collapse. The crew should clean the sewer line as described below.
• Using a high velocity jet-flushing vehicle, begin flushing from the downstream manhole
against the flow to the upstream manhole.
• Repeat this procedure for several upstream and downstream pipe reaches.
• The crew leader should thoroughly document the nature and extent of the impacts
including the use of photographs and video footage where possible.
• Make out a report indicating the time of the call,a description of the problem,the repair
work done,personnel present and equipment used.

5.3 Emergency Support
Addressing some problems may require resources beyond the Town of Old Fort Maintenance
Dept forces. This is particularly true of main line breaks where there is a risk of a significant
sewer overflow. In these situations,the Maintenance Dept may enlist the aid of Gross
Industries. The Town of Old Fort Maintenance Dept through Gross maintains an agreement
with several companies for situations that require the prompt reconstruction of sewer lines.
These companies are capable of mobilizing construction equipment and personnel quickly to
handle emergency assignments.This response time and the level of response will vary due to
several factors, some are identified below:
• Location of the sewer repair in relation to the contractor's equipment yard
•Scope of the repair,size of sewer,depth of sewer and volume of flow
•The size,type and availability of equipment and number of workers
• The time of day, day of the week and the proximity to a holiday
• Weather conditions,clear,rain,snow, extreme cold or heat
6. OVERFLOW REPORTING
6.1 Overview
The Collection System ORC completes an Overflow Report.The Responsibilities Chart in
Section 1 and the Notification Matrix in Section 4 provide guidance on proper reporting. The
Collection System ORC or designee promptly notifies appropriate department and agencies
when the overflow is eliminated. The information collected will also provide the Maintenance
Dept with valuable information to inform decisions regarding collection system rehabilitation
and replacement,scheduling, staffing,equipment needs,budgeting and updating this and other
emergency response plans.
Note:NCDENR/DWR,Office of DWQ must be contacted within 24 hours of when the
69

community becomes aware of an SSO.Between the hours of 8:30 AM and 4:00 PM,the DWQ
Section can be reached at 296-4500. When calling to report a wastewater emergency or bypass, it
is important to actually speak with a DWQ staff member, DO NOT leave a recorded message. If
someone from the DWQ section is not available, speak with the receptionist and give them the
general information;they will then contact an appropriate staff member.
6.2 Reporting Details
• The dispatcher provides details on the time, location,description, and map locations of
overflows
•The start time of the sewer overflow is determined by one of the following methods:
a. Date and time information received and/or reported to have begun and later substantiated
by a sewer investigator or response crew;
b.Visual observation;
•The stop time of the sewer overflow is determined by one of the following methods:
a. When the blockage is cleared or flow is controlled or contained; or
b. The arrival time of the sewer investigator or response crew, if the overflow stopped
between the time it was reported and the time of arrival.
•An estimation of the rate of sewer overflow is made by one of the following criteria(See
Appendix S.O.V.for guidance on estimating sewer overflow volumes and flow rates):
a. Direct observations of the overflow; or measurement of actual overflow from the sewer
main.
b. When the rate of overflow is known gallons per minute(GPM),the duration of the
overflow is multiplied by the overflow rate; or when the rate of overflow is not known,the
surrounding area is investigated for evidence of ponding or other indications of overflow
volume.
•Visual observations should be recorded for any unusual observations
•Photographs and videotapes are taken at the event and response when possible.
•The nature and extent of any damage or impacts to public/private property are assessed.
•Repair crews provide a report indicating the time of the call, a description of the problem,the
repair work done,personnel present and equipment used
Reports are kept in the collection system logbook to determine patterns and trends and to provide
input to our asset management program.
6.3 Customer Satisfaction
The Maintenance Dept Supervisor confirming the overflow follows up in person or by telephone
with the citizen(s)reporting the overflow. The cause of the overflow and its resolution will be
disclosed.

Appendix S.O.V.
Guidance on estimating sewer overflow volumes1
A variety of approaches exist for the estimation of the volume of a sanitary sewer
overflow. This appendix documents methods that are often employed. Other methods are also
possible. The person preparing the estimate should use the method most appropriate to the SSO
using their judgment.
Method 1 "Visual Estimate"
The volume of very small spills can be estimated by imagining the amount of water that
would spill from a 5-gallon bucket or 50 gallon barrel.If the spill is larger than the amount of
liquid from a 50 gallon barrel,try to visnaii7.P how many barrels the standing water would fill
and them multiply by the number of barrel volumes by 50. This method can be useful for
contained spills that are not more than a couple of hundred gallons.
Method 2"Measured Volume"
The volume of some small spills can be estimated using this method if it is not raining.
The shape dimensions and depth of the spilled wastewater are needed to use this method. The
shape dimensions are used to calculate the area of the spill and the depth calculates the volume.
1. Sketch the shape of the contained area of sewage
2.Measure or pace off the dimensions and add the dimensions to your sketch
3.Measure the depth in several locations and then average the depth for the spill. (If the shape
and depth vary,break your sketch into sections and calculate the volume of each by repeating the
steps below)
4. Convert the dimensions to feet(if they are not in feet to begin with)
5. Calculate the area using the following formulas (depending on the shape of the spill):
Rectangle Area length X width
Circle Area=diameter X diameter X 0.785
Triangle Area=base X height X 0.5
6. To get the volume in cubic feet,multiply the area times the average of the depths you
measured
7.Multiply the volume by 7.5 to convert to gallons
Method 3 "Duration and Flow Rate"
Calculating the volume of spills where it is difficult or impossible to measure the area
and depth requires a different approach. In this method separate estimates are made of the
duration(the elapsed time from the start of the overflow to the time the spill is stopped)of the
spill and the flow rate.
Start time can be difficult to establish. Here are two approaches to estimating start time:
For very large overflows,changes in flow on a downstream flow meter can be used to
establish the start time. Typically,the daily flow peaks are "cut off"of flattened by the loss of
flow.This can be identified by comparing hourly flow data on the downstream flow meter.
Conditions at a spill site may change with time.Initially,there will be limited deposits of
grease and toilet paper. After a few days to a week,the grease forms a light colored residue.
After a few weeks to a month the grease turns dark. In the latter two cases the quantity of toilet
paper and other materials of sewage origin increase in amount. These changes with time can be
I Adapted from information in the following guidance and reporting document:
http://www.swrcb.ca.gov/rwgcb2/news_itemss/sso%20reporting%20requirements%20nov%2011%202004.pdf
71

used to estimate the start time in the absence of other information.
Sometimes it is simply not possible to estimate the start time and the date that the
overflow was first observed should be used on the form.
End time is usually much easier to establish.Field crews on site observe the"blow down"
that occurs when the blockage has been removed.The end can also be observed in downstream
flow meter readings.
Flow Rate:
One way to estimate flow rate is to look at changes in flow rates in the downstream flow
meters to estimate how much of the flow rate was lost during the spill(this generally only works
for large SSOs)
A second way to estimate flow rate is to base it on up-stream connections: Once the
location of the spill is known,the number of upstream connections can be determined from
records or your computerized system.Multiply the number of connections by 200 to 250 gallons
per day per connection or 8-10 gallons per hour for each connection(or other flow rates that are
} consistent with your data for your connections).
Once duration and flow rate have been estimated,the volume of the spill is the product of the
duration in hours(or days)times the flow rate in gallons per hour(or gallons per day).

TOWN OF OLD FORT 2018 WASTEWATER ASSET INVENTORY AND ASSESSMENT REPORT
EXECUTIVE SUMMARY
This Asset Inventory and Assessment Report covers the Town of Old Fort Wastewater Treatment Plant and
sanitary sewer system. This Report describes how the utility will manage these infrastructure assets.The
WWTP has a design capacity of 0.5 MGD and currently manages an average of 0.164 MGD.Based on projected
McDowell County population growth,wastewater flow in Old Fort is projected to increase to approximately
170,700 gpd average by 2037;still way below the WWTP's permitted capacity. See Tables 2.2 and 2.3. The
following items summarize the utility's asset review and plan to provide for long-term improvements in the
operation and maintenance of the sanitary sewer system and WWTP:
Table 4.1 contains an inventory of treatment train components at the Old Fort Wastewater Treatment Plant
(WWTP). The table also contains an assessment of each component including age,condition,consequence of
failure,replacement year,risk factor category,and action based on risk., Table 6.1 establishes the proposed
improvements at the WWTP.
Several sections of the existing sanitary sewer system were selected by the Town to be video inspected as
part of the sewer system assessment. A copy of the resulting Video Inspection Report is included in Appendix
B. Table 6.2 is a condition assessment of those videoed sewer lines.
-7' It is estimated that the utility will spend between$42,000 and$52,500 per year for the next 10 years for
sewer system rehabilitation projects out of fund balance. A financial summary for the annual expenditures
for sewer system improvements is presented in Table 6.3. Table 6.4 provides the projected expenditures for
both WWTP and sewer system expenditures by fiscal year including anticipated rate increases needed to
fund the WWTP improvements,assuming loans will be acquired for the WWTP improvements.
Table 6.5 presents the Total Projected Expenditures for the Water and Sewer Department,proposed
utilization of reserve funds and anticipated sewer rate increases over the 10-year CIP. By contributing
$104,000 in FY 2019-2020 and 100,000 in FY 2020-2021 from reserves to the Water and Sewer Budget,the
Town may be able to keep its sewer rates at their current level. The major improvements at the wastewater
treatment plant are proposed to be funded through a State Revolving Loan in FY2024-2025. The annual debt
service for these improvements,assuming 2.25%interest rate and a 20-year term,has been included in the
Sewer System CIP beginning in FY 2024-2025.
It is expected that it will not be necessary to increase sewer rates through the 10-year term of the CIP. See
Table 6.5.
The operating ratio will be greater than or equal to 1.0 during the next 10 years.

Best Management Practice and Guidance Manual for Food Service Establishments prepared
by the City of for the control of fat, oil and grease (FOG)
discharged to the sanitary sewer system by Food Service Establishments.
Introduction
Best management practices (BMPs) help facilities meet environmental regulations and
prevent pollution. This best management practice contains guidelines to reduce the amount
of fat, oil and grease (FOG) discharged to the City of sanitary sewer
system and wastewater treatment plants. Our intent is to reduce the amount FOG
introduced to the City's sanitary sewer system and protect the public health and
environment from hazards caused by sanitary sewer overflows.
The Clean Water Act was established to protect wastewater plants and the streams they
discharge to. The U.S. Environmental Protection Agency and the Florida Department of
Environmental Protection require local governments or utilities to protect their systems and
the receiving streams from FOG-related problems.
Background
All food service establishments generate varying amounts of FOG. While fat, oil and grease
are most commonly associated with fried foods, they are generated in significant quantities
in all types of commercial food preparation:
• Cooking meats
• Mayonnaise and salad dressings
• Butter, ice cream and other dairy products
• Creams and sauces
What's the Problem?
FOG coats pots, pans, utensils and equipment. When these materials are washed, FOG is
rinsed into the sewer.
Sanitary sewer systems are not equipped to handle FOG. In the sewer, FOG coats the
interior surface of the pipes. Over time, FOG accumulations restrict the flow of wastewater
through the sewer. Eventually the FOG can clog the sewer pipes causing the sewage to
back up and spill onto the ground, or into waterways, homes or buildings. This is called a
sanitary sewer overflow (SSO), which endangers the public health and the environment.
Fat, oil and grease can also interfere with proper operation at the wastewater treatment
facility (WWTF). This could result in poor wastewater treatment and pollution of the St.
Johns River.
Policy
Discharges of fat, oil and grease cause major problems in the sewer system and treatment
plants. The City of is required to regulate discharges from food service
establishments to prevent these sewer problems. This manual will help you use best
management practices to minimize the amount of FOG entering the sewer system and
treatment plants. Keeping FOG out of the sewer will help prevent a sewer backup in your
facility or a sewer overflow on your street.

Fat, Oil and Grease Discharge Policy
1. All discharges from Food Service Establishments must be in accordance with applicable
state, local or federal rules and regulations.
2. All Food Service Establishments must have a properly sized and operational grease
interceptor(large external device) or grease trap (smaller "under the sink"fixture).
3. Sizing and design of grease traps and interceptors must meet the criteria in the Florida
Building Code, Chapter 10, Plumbing
4. All FOG bearing drains must be plumbed to the interceptor.
5. All grease interceptors and traps must be maintained on a regular basis.
Required Maintenance Practices
To prevent introduction of FOG to the sanitary sewer, grease
interceptor devices must be maintained on a regular basis. Interceptors must have all FOG
removed and hauled off site for proper disposal at a minimum frequency of once every 90
days unless otherwise determined by the City . Interior "under the
sink"grease traps must have the entire contents removed and hauled offsite for proper
disposal at a minimum frequency of once every 90 days unless otherwise determined by the
City of . It is recommended that these devices be maintained at a
weekly frequency. This will help extend the life of these fixtures. Maintenance of interior
grease traps can be performed by the Food Service Establishment as long as the trap
contents are properly disposed.
FOG must be removed and hauled off site for proper disposal any time the volume of grease
and solids factions exceeds 25% of the interceptor's or trap's functional volume. At a
minimum frequency of once per year all contents of grease interceptor must be removed
and hauled off site. Grease interceptor devices must be inspected for proper functionality
during each pump out event.
Kitchen Practices - strictly control the discharge of grease and solids to the interceptor. By
reducing the amount of these substances discharged, a Food Service Establishment may be
able to reduce the cost associated pump out frequency. This practice will also lead to
decreased plumbing maintenance cost.
Fryer oil (yellow grease) must not be disposed of through the sanitary sewer. Yellow grease
has re-use value and should be placed in a secured tank. Contract with a rendering service
to haul the grease offsite for beneficial re-use.
Reduce the amount of food particles washed down the drain. Food particles take up volume
in the grease interceptor, resulting in increased pump out frequency.
One way to reduce pump out frequency is to not use grinders or garbage disposal
units. Ground food takes up volume in the grease interceptor, resulting in increased pump
out frequency.
Use rubber scrapers and paper towels to wipe off grease from pots, pans and ware into
garbage cans before washing.
Clean up all grease spills with paper towels and dispose of in the garbage. Avoid washing
straws, disposable gloves, paper towels or any other inappropriate materials down the
drain.
Use a test kit provided by your grocery distributor to determine when to change the oil in

fryers. This extends the life of both the fryer and the oil. Build-up of carbon deposits on
the bottom of the fryer acts as an insulator that forces the fryer to heat longer, thus causing
the oil to break down sooner.
Develop a rotation system if multiple fryers are in use. Designate a single fryer for products
that are particularly high in deposits, and change more often.
Documentation
For every grease interceptor/trap pump out event, whether performed by the Food Service
Establishment or a hauler, a City of Out Report must be submitted to
the City within seven (7) days of the event. All records of pump outs or interceptor
maintenance must be maintained on site and available for City inspection for a minimum of
three (3) years.
Training
-- Train all kitchen staff in these best management practices and the environmental impacts
of grease in the sewer system.
-- Post Best Management Practices signs in kitchens and near sinks.
-- Place yellow grease re-use bins in easy access areas for staff. Follow up to ensure staff
properly disposes of grease.
-- Provide constant re-enforcement on proper disposal of fat, oil, and grease with staff.
Interceptor Additives
Many vendors service grease interceptors with chemicals or microorganisms to remove FOG
material. Known interceptor additives are:
Emulsifiers, detergents, or caustic substances - these chemicals act to break up the grease
and allow it to pass through the interceptor and into the sewer system where it can reform

Enzymes - have the same effect as emulsifiers and are therefore prohibited as additives.
Microorganisms - typically cultured bacteria are added to the interceptor. Ideally these
bacteria digest the FOG converting it to innocuous substances. Microorganisms are allowed
as an additive. However, since bacteria need an environment with specific requirements to
proliferate, the effectiveness of these organisms in the environment of the interceptor is not
known. The use of microorganisms does not relieve a FSE of the minimum pump out
frequency requirements.
Guidance for Working with Grease Hauling Companies
Work closely with your hauling company to make sure your interceptor is serviced at the
proper frequency and all required paperwork is completed properly and submitted to the
in a timely manner.
Be sure your hauler leaves a copy of each pump out report and any other interceptor
maintenance documentation.
Review your pump out reports from haulers for accumulations of grease and solids. If
amounts are nearing or exceeding 25% review kitchen practices to find areas in which
improvements can be made to reduce the introduction of FOG and solids. If the pump out
report indicates that the interceptor is in need of repair, contact hauler or plumber to have it
serviced immediately.

Ask your hauler where/how grease interceptor contents are disposed.
