Purpose and Intent
The Town of Waynesville is committed to ensure that the stormwater runoff from its facilities,
streets, and private businesses complies with the State regulations and applicable provisions of
the Clean Water Act (1987). The provisions of the Clean Water Act require National Pollutant
Discharge Elimination System (NPDES) permits for stormwater discharges. Waynesville has
been issued the NPDES permit on August 19, 2021, and it is valid for five years.
Section 402 (p)(3)(B)(ii) of the Clean Water Act requires that permits for Municipal Separate
Storm Sewers (MS4s) include a requirement to effectively prohibit problematic non-storm water
discharges into storm sewers. Emphasis is placed on the elimination of inappropriate connections
to urban storm drains. This requires permittees to identify and locate sources of non-storm water
discharges into storm drains so they may institute appropriate actions for their elimination.
This Illicit Discharge Detection and Elimination (IDDE) Plan addresses the illicit discharges,
illegal dumping, spills, and any non-stormwater discharges identified as significant contributors
of pollutants to the MS4. The Plan has been prepared in compliance with the Waynesville
NPDES permit No. NCS000501 “To Discharge Stormwater Under the National Pollutant
Discharge Elimination System.” Its intended audience is Town staff who need to understand and
implement the program, State and Federal agencies that provide oversight and review, volunteers
and nonprofit organizations that are interested in collaborating and promoting public awareness,
and the general public for community education.
This plan will be evaluated annually and updated as necessary. It will be submitted to the North
Carolina Department of Environmental Quality (NC DEQ) for approval once per permit term
(every 5 years), as required by the BMP #21 of the 2021 Town of Waynesville Stormwater
Management Plan.
Waynesville IDDE Plan draws on the work performed by the Center for Watershed Protection in
cooperation with Robert Pitt of the University of Alabama, Stormwater Phase II Final Rule Fact
Sheet by the Environmental Protection Agency (EPA), and MS4 Program Evaluation Guidance by
the EPA. The Plan incorporates the following procedures and documentation:
a) Locate priority areas likely to have illicit discharges,
b) Conduct routine dry weather inspections of all major outfalls,
c) Identify illicit discharges and trace sources,
d) Eliminate the sources of an illicit discharge, and
e) Evaluate and assess the IDDE Program.
The plan has two parts: Illicit Discharge Overview and Waynesville Illicit Discharge
Program.
4| IDDE Plan, Waynesville, NC, 2022
Part I: Illicit Discharge Overview
1.1 Illicit Discharges and Connections
Understanding the nature of illicit discharges in urban watersheds is essential in order to find,
eliminate, and prevent them. This section defines the terms related to illicit discharges, provides
examples, and presents the regulatory context by the State and Federal agencies as well as local
Town Ordinance.
The EPA defines an illicit discharge as “...any discharge to an MS4 that is not composed
entirely of stormwater...” with some exceptions, such as discharges from NPDES-permitted
industrial sources and discharges from fire-fighting activities.
The EPA’s guidance manual by the Center for Watershed Protection- Illicit Discharge Detection
and Elimination, A Guidance Manual for Program Development and Technical Assessments
(2004)- provides a comprehensive definition of an illicit discharge that consists of four parts:
1. Illicit discharge is a storm drain that has measurable flow during dry weather containing
pollutants and/or pathogens. A storm drainage with measurable flow but no pollutants is a non-
illicit discharge.
2. A discharge that has a unique frequency, composition, and mode of entry into the storm drain
system.
3. A discharge may be caused by the interaction of sewage disposal and storm drain systems.
4. A discharge may be produced from known source areas and operations known as “generating
sites.”
Illicit discharges are considered “illicit” because MS4s are not designed to accept, process, or
discharge these non-stormwater wastes. They result in untreated flows to the stormwater system
and significantly degrade water quality, disrupt aquatic habitats, and pose serious risks to human
health and wildlife. Pollutants commonly found in illicit discharges include:
• Heavy metals
• Toxins
• Grease and oil
• Paint
• Solvents
• Nutrients
• Raw sewage (viruses and bacteria).
The Town of Waynesville Illicit Discharge Ordinance also lists specifically prohibited
substances. They include: anti-freeze, chemicals, animal waste, paints, garbage, and litter
(Waynesville Code of Ordinances, Appendix A, Section 12.5.9).
5| IDDE Plan, Waynesville, NC, 2022
Waynesville has been experiencing a rapid growth with 780 new units of multi-family projects
(apartments, townhomes) and the construction of hundreds of single-family homes over a three-
year period. Such concentrated infill development substantially increases impervious surfaces,
including the number of town streets, driveways, parking lots, and sidewalks. Pollutants from
concentrated human activities settle on the impervious surfaces and remain there until a storm
event washes them directly into nearby storm drains and waterways.
The EPA identifies the common sources of illicit discharges:
• Sanitary wastewater
• Effluent from septic tanks
• Car wash wastewaters
• Improper oil disposal
• Radiator flushing disposal
• Laundry wastewaters
• Spills from roadway accidents
• Improper disposal of auto and household toxins
Other examples of illicit discharges include excess road salt, fertilizers, pesticides, herbicides,
leaves and grass clippings blown into the storm drains, sediment, and other debris.
The Town of Waynesville Illicit Discharge Ordinance specifically prohibits illicit discharges to
the storm sewer system. However, some non-stormwater discharges are allowed if they do not
significantly impact water quality. These discharges include:
• Residential vehicle washing
• Filter backwash and draining associated with swimming pools
• Discharges from fire-fighting activities
• Uncontaminated ground water
• Irrigation water
• Street wash water
• Condensate from residential or commercial air conditioning
• Collected stormwater from foundation or footing drains
• Collected ground water and infiltrated stormwater from basement or crawl space pumps
• Discharges from pumping or draining of natural watercourses
• Filter backwash and draining associated with raw water intake screening and filtering
devices
• Flushing and hydrostatic testing water associated with utility distribution systems
• Discharges associated with emergency removal and treatment activities, for hazardous
materials, authorized by the federal, state, or local government on-scene coordinator
• Flushing and cleaning of stormwater conveyances with unmodified potable water
• Wash water from the cleaning of the exterior of buildings, including gutters, provided
that the discharge does not pose an environmental or health threat.
6| IDDE Plan, Waynesville, NC, 2022
An illicit discharge also includes illicit connections. An illicit connection occurs when
drainpipes or other conveyances are improperly connected to the storm drain system. These
connections pose significant threats to wildlife and human health. For example, illicit
connections to sanitary sewers can result in fecal coliform bacteria entering the storm sewer
system. Fish kills, destruction of spawning, loss in aesthetic value, and contamination of
drinkable water are also among the results of illicit connections.
1.2 Important Terminology
a). Stormwater System vs Sanitary Sewer System
This plan consistently mentions the terms “stormwater system” (or “storm drain system”) and
“sanitary sewer system.” It is important to understand the difference between them:
• Water that flows to the stormwater system of curb inlets, pipes, and ditches on the
streets goes directly into local water bodies. This water does not get treated at the plant.
Stormwater systems are also called storm sewer systems.
• Water that goes to the sanitary sewer system through toilet flushing, shower drains, etc.,
is treated at the wastewater treatment plant to achieve certain quality before it gets
discharged into a creek or stream.
b). Point Source vs Nonpoint Pollution
The EPA identifies two broad categories of pollution: point source and nonpoint source. Point
source pollution comes from a single place. Nonpoint source pollution comes from many
places, often all at once, and it is hard to identify.
c). Storm Drain
A storm drain can be either an enclosed pipe or an open channel. From a regulatory standpoint,
major storm drains are defined as enclosed storm drainpipes with a diameter of 36 inches, or
greater or open channels that drain more than 50 acres. For industrial land uses, major drains are
defined as enclosed storm drainpipes 12 inches or greater in diameter and open channels that
drain more than two acres. Minor storm drains are smaller than these thresholds.
Both major and minor storm drains can be a source of illicit discharges, and both merit
investigation. Some “pipes” found in urban areas may look like storm drains but actually serve
other purposes. Examples include foundation drains, weep holes, culverts, etc. These pipes are
generally not considered storm drains from a regulatory or practical standpoint. Small diameter
“straight pipes,” however, are a common source of illicit discharges in many communities and
should be investigated to determine if they are a pollutant source.
Not all dry weather storm drain flow contains pollutants or pathogens. Indeed, many
communities find that storm drains with dry weather flow are, in fact, relatively clean. Flow in
these drains may be derived from springs, groundwater seepage, or leaks from water distribution
7| IDDE Plan, Waynesville, NC, 2022
pipes. Water quality testing and monitoring are important in confirming whether pollutants are
actually present in dry weather flow.
d). Conveyance
Conveyance is a structured system of transferring stormwater between at least two points. It
includes pipes, ditches, swales, catch basins, storm drains, roadways, etc.
e). Discharge Frequency
The frequency of dry weather discharges in storm drains is important, and can be classified as
continuous, intermittent, or transitory. Continuous discharges occur most or all of the time.
They are usually easier to detect and typically produce the greatest pollutant load. Intermittent
discharges occur over a shorter period of time (e.g., a few hours per day or a few days per year).
Because they are infrequent, intermittent discharges are hard to detect, but can still represent a
serious water quality problem, depending on their flow type. Transitory discharges occur
rarely, usually in response to a singular event, such as an industrial spill, ruptured tank, sewer
break, transport accident, or illegal dumping episode. These discharges are extremely hard to
detect with routine monitoring. Under the right conditions, they can cause severe water quality
problems in downstream receiving waters.
f). Discharge Flow Types
Dry weather discharges are composed of one or more possible flow types:
• Sewage and septage flows are produced from sewer pipes and septic systems.
• Wash water flows are generated from a wide variety of activities and operations.
Examples include discharges of gray water (laundry) from homes, commercial carwash
wastewater, fleet washing, commercial laundry wastewater, and floor washing to shop
drains.
• Liquid wastes refer to a wide variety of flows, such as oil, paint, and process water
(radiator flushing water, plating bath wastewater, etc.) that enter the storm drain system.
• Tap water flows are derived from leaks and losses that occur during the distribution of
drinking water in the water supply system.
• Landscape irrigation flows occur when excess potable water used for residential or
commercial irrigation ends up in the storm drain system.
• Groundwater and spring water flows occur when the local water table rises above the
bottom elevation of the storm drain (known as the invert) and enters the storm drain
either through cracks and joints, or where open channels or pipes associated with the
MS4 may intercept seeps and springs.
8| IDDE Plan, Waynesville, NC, 2022
Water quality testing is used to conclusively identify flow types found in storm drains. Each flow
type has a distinct chemical fingerprint.
g). Mode of Entry
Illicit discharges can be further classified based on how they enter the storm drain system. The
mode of entry can either be direct or indirect. Direct entry means that the discharge is directly
connected to the storm drainpipe through a sewage pipe, shop drain, or other kind of pipe. Direct
entry usually produces discharges that are continuous or intermittent. Direct entry usually occurs
when two different kinds of “plumbing” are improperly connected. The three main situations
where this occurs are: sewage cross-connections (a sewer pipe that is improperly connected to
the storm drain system), straight pipe (small diameter pipes that intentionally bypass the
sanitary connection or septic drain fields, producing a direct discharge into open channels or
streams), and industrial and commercial cross-connections (a drain pipe is improperly
connected to the storm drain system producing a discharge of wash water or other inappropriate
flows into the storm drain pipe).
Indirect entry means that flows generated outside the storm drain system enter through storm
drain inlets or by infiltrating through the joints of the pipe. Generally, indirect modes of entry
produce intermittent or transitory discharges, with the exception of groundwater seepage. The
five main modes of indirect entry for discharges include: groundwater seepage, spills,
dumping, outdoor washing activity, and non-target irrigation.
h). Impervious Surface
The Town of Waynesville Ordinance defines impervious surface as any hard-surfaced, man-
made area that does not readily absorb or retain water, including but not limited to building
roofs, parking and driveway areas, graveled areas, block pavers (unless allowing vegetative
growth though the pavers), roads, sidewalks, and paved recreation
areas. Impervious surface includes all structures measured at their greatest extent and so as to
include areas overhung by eaves, balconies, and other projecting features of the structure.
Wooden slatted decks and the water area of a swimming pool are considered pervious
(Waynesville Code of Ordinances, Appendix A, Section 17.4).
i.) Outfall
Outfall is a point source where a municipal separate storm sewer discharges to the waters of the
United States. It does not include open conveyances connecting two municipal separate storm
sewers, pipes, tunnels, or other conveyances which connect segments of the same stream or other
waters and are used to convey waters of the United States.
1.3 Generating Sites
Land use can predict the potential for indirect discharges. Many indirect discharges can be traced
and prevented by identifying “generating sites,” which are sites where common operations can
generate indirect discharges in a community.
9| IDDE Plan, Waynesville, NC, 2022
Land uses, generating sites, and activities that have the potential to produce illicit discharges in
Waynesville are listed in the table below:
Residential
(single-family, multi-family, apartments)

• Road maintenance/street washing
• Landscaping/Grounds care
• Outdoor fluid storage
10| IDDE Plan, Waynesville, NC, 2022
Part II: Waynesville Illicit Discharge Program
2.1 Overview and Challenges
Eliminating illicit discharges is a critical component to restoring urban watersheds and
maintaining water quality. The Town of Waynesville is in the Pigeon River sub-basin of the
French Broad River watershed. The stormwater conveyance systems discharge into the primary
receiving waters: Richland Creek, Browning Branch, Hyatt Creek, Camp Branch, Plott Creek,
Allens Creek, Raccoon Creek, Shelton Branch, Eaglenest Creek, Farmer Branch, Shingle Cove
Branch, and Factory Branch. These creeks have primary designations as either Trout Waters,
Class C fishable/swimmable waters, or class B protected waters for recreation, as classified by
the NC Division of Water Resources (DWR).
When bodies of water cannot meet designated uses for drinking water, fishing, or recreation, the
risks to public health arise, tourism may decline, fishing may be restricted, and creeks may be
closed for recreation due to bacteria. In addition to the public health and economic impacts
associated with illicit discharges, significant impacts to aquatic life and wildlife are realized.
Numerous fish kills and destruction of habitats may result from pollutants in waterways.
As a small municipality, the Town of Waynesville needs simple, yet comprehensive approach to
address and monitor illicit discharges within its jurisdiction. The purpose of Waynesville’s IDDE
program is to find, fix, prevent illicit discharges, and develop a series of procedures to meet these
objectives. The prospect of developing and administering an IDDE program is complex and
challenging for Waynesville. The main reasons are:
• Staffing
As a Town with the population of just over 10,000 residents, Waynesville has limited staff and
budget to create a position of a Stormwater Administrator who would be implementing the IDDE
program full-time. The IDDE program implementation is divided between the Development
Services Department and Haywood Waterways, a nonprofit organization that the Town
contracts.
• Other Permit Holders
There are a couple of large entities that hold their own Stormwater permits in Waynesville. Due
to the scope of their operation and nature of their activities, they pose a risk of generating illicit
discharges in the Town limits. The entities are:
1. The North Carolina Department of Transportation (NC DOT) is the largest MS4 in the
State. Waynesville has a good amount of the NC DOT-owned roads that pass through the
town. Road maintenance and road construction activities have a potential to generate
illicit discharges.
2. The largest supplier of Epsom Salt in North America- Giles Chemical- is located in
Waynesville. The factory holds a separate NPDES Industrial Stormwater Permit (permit
11| IDDE Plan, Waynesville, NC, 2022
number NCGNE0905). Waste disposal, facility cleanup, and grounds maintenance
activities have a potential to generate illicit discharges.
• Wastewater Treatment Plant
Waynesville Wastewater Treatment Plant is set up for renovation. It is operating under the
Special Order of Consent (SOC) from the State. The old age of our sewer system is something
that we definitely need to be aware of.
Through communication and sharing information with other permit holders, Waynesville can
enhance its IDDE Program and make it easier to find, fix, and prevent illicit discharges that may
relate to these major entities and their activities. For example, Waynesville has already requested
an asset inventory from the NC DOT, including their interconnections and map of their outfalls
in town limits. Although the request has been pending since August 18th, 2021, the NC DOT has
assured us that the asset inventory is being put together. The inventory of the NCDOT
stormwater assets in the Town limits will help to monitor the discharges that may come from
them.
2.2 Implementation of Illicit Discharge Requirements in Waynesville Stormwater
Permit
1. Develop, update, and maintain a municipal storm sewer system map including stormwater
conveyances, flow direction, major outfalls and waters of the United States receiving
stormwater discharges.
The Town periodically updates its storm drain system map that includes new major outfalls and
receiving streams. The Town of Waynesville Outfall Map has been last revised in July 2020
(Appendix C). It will be updated continuously, at least once per permit term (5 years). Once
completed, the map will aid Waynesville to complete dry weather screening of the outfalls and
remove illicit connections. The outfall inspections will begin in Spring 2022.
In addition, the Town has a comprehensive Stormwater Map which shows the location of
outfalls, storm drains, catch basins, major water bodies, streams, grease traps, and stormwater
control measures (SCMs) within Waynesville. It serves as a comprehensive resource for various
components of Waynesville Stormwater Program, including identifying additional sources of
illicit discharges. The map was last updated in January 2022, and it is included in Appendix E of
this document. The Stormwater Map is also uploaded on the arcgis.com website to allow the
general public to interact with the map by zooming to features, selecting them, and getting
information about them. The link to this map is provided on the Town’s Stormwater page:
https://www.waynesvillenc.gov/departments/development-services/stormwater-management
The EPA considers dry weather screening an effective method for identifying illicit discharges
and connections. Waynesville will start dry weather screening (no rain in previous 72 hours)
within its area in Spring 2022. Any major outfall observed to be flowing during dry weather
screening will be investigated as a potential illicit discharge. A survey of 20% of the storm drain
system outfalls per year will be conducted and the findings will be documented. Development
12| IDDE Plan, Waynesville, NC, 2022
Services Department, Public Works, and Haywood Waterways will collaborate in identifying,
inspecting, and mapping the outfalls.
2. Provide an IDDE ordinance or other regulatory mechanism that provides legal authority to
prohibit, detect, and eliminate illicit connections and discharges, illegal dumping, and spills
into the MS4, including enforcement procedures and actions.
The three main sources of legal authority for Waynesville are the Illicit Discharge Ordinance,
IDDE Plan, and Standard Operating Procedure for Illicit Discharges.
The Town has the Illicit Discharge Ordinance in the Waynesville Code of Ordinances, Appendix
A, Section 12.5.9. It is a part of the larger Stormwater Ordinance. The Ordinance became
effective in April 2011. It explicitly prohibits specific non-stormwater discharges, connections,
and spills. It defines the period of compliance and outlines the responsibilities of the persons in
control of the polluting substances. The full text of this Ordinance can be found in the Appendix
A of this document. The Stormwater and Illicit Discharge ordinances are currently being updated
to align them more closely with the with the NCDEQ Stormwater Model Ordinance for North
Carolina.
The enforcement mechanisms available to the Town in addressing illicit discharges are described
in Section 16.2 Penalties for Violation and Enforcement Mechanisms. The remedies include civil
penalties, injunctive relief, order of abatement, execution of court decisions, and revocation of
permits. The full text of this Ordinance can be found in the Appendix B of this plan.
The Town will maintain its legal authority by reviewing and updating the existing ordinances
once per permit term (5 years). The ordinances will be adopted by the governing Board of
Aldermen, and all the public notification requirements will be met.
The Town will also review and revise its additional regulatory mechanisms, such as the IDDE
Plan and the Standard Operating Procedure (SOP) for Illicit Discharges. These additional
regulatory mechanisms will be reviewed annually and updated as necessary, at least once per
permit term (5 years). The Standard Operating Procedure (SOP) for Illicit Discharges and
Reporting Form are shown below:
13| IDDE Plan, Waynesville, NC, 2022
Prerequisites
1. Employees should attend IDDE and general Stormwater pollution prevention training.
2. Employees performing the procedures in this SOP should review and refer to the materials in
the References and Related Procedures section of this SOP.
General:
1. The Town is responsible for monitoring illicit discharges/connections within its MS4. Non-
stormwater discharges into the city drainage system are not allowed by any person, and they
are a violation of the Town ordinance “Illicit Discharges and Connections” (Land
Development Standards, Sec. 12.5.9.).
2. If an Illicit Discharge is detected through routine inspection or a complaint, the inspector,
Administrator, or other appropriately trained personnel must take measures to cease and
eliminate the illegal disposal as described in this plan. For the purpose of this plan, the terms
inspector and administrator can be used interchangeably.
Verbal Notification:
1. If the source of the connection/discharge is evident, the inspector will contact the
connector/discharger directly by phone or in person to discuss the discharge. The
communication will include requesting any permits or other authorizations, and if no permits
exist or they are in violation of the permits, then the discharger will be given a verbal order
to bring the discharge into compliance under the permit or to immediately cease and
eliminate the discharge if they don’t have a permit. A follow-up date to check for
compliance will be given to the discharger. Follow up inspections must occur within one
week of the initial notification.

required.
4. If the discharge was not permitted, a follow up inspection will be performed by the inspector.
1st Written Notification:
1. If no action has been taken, the inspector will issue a “Notice of Violation” to the
connector/discharger, property owner, or facility operator, as appropriate.
2. The inspector will provide information and guidance on complying with the Town
Stormwater ordinance.
3. The letter will contain a schedule for compliance and describe various enforcement options
and penalties available to the Town if the connection/discharge is not corrected or
appropriate corrective action is not administered. The enforcement actions and penalties
available to the Town include:
a) Withholding a certificate of occupancy
b) Disapproval of subsequent permits
c) Other penalties and as set forth in the Town of Waynesville Code of Ordinances,
which may include civil penalties, relief of incurred damages, and criminal penalties.
4. If the situation is not resolved within the timeframe established in the letter, the inspector will
notify the local NCDEQ office of the reported Notice of Violation.
5. A follow up inspection will be performed by the inspector within a week or as described in
the Notice of Violation.
2nd Written Notification / Civil Penalty:
1. If no action has been taken, or deficiency has not been corrected within the timeframe
established in the Notice of Violation, the inspector will issue a “Letter of Warning” to the
property owner. The letter will demand that the connection/ discharge be ceased or removed
immediately and establish the date on which the civil penalty starts for each day the violation
continues, as described in Land Development Standards, Section 16.2.2. Civil Penalties.
2. A civil penalty will be recovered by the Town in a civil action in the nature of debt if the
offender does not pay the penalty within the prescribed period of time (Land Development
Standards, Sec. 16.2.2. Civil Penalties).
3. A follow up inspection will be performed by the inspector within a week.
Legal Action:
1. If the illegal connection/discharge is not corrected, the inspector notifies the Town Manager
and the Town Attorney with accompanying documentation for corrective action, as
described in the Criminal Penalties (Sec. 16.2.3), Injunctive or Other Relief (Sec. 16.2.4),
15| IDDE Plan, Waynesville, NC, 2022
Equitable Remedy (Sec. 16.2.5), and Order of Abatement (Sec. 16.2.6) of the Land
Development Standards.
2. The Town may apply other enforcement options or obtain assistance from other agencies it
deems necessary to complete the corrective action.
Construction Site Inspections:
1. If a severe pollutant discharge or other serious deficiencies are detected during a routine
construction site inspection, the Permit Holder shall be notified in person or by phone to
immediately cease the violation and comply with all requirements of the ordinance and
Stormwater Management Plan and take appropriate remedial action to properly address the
violation. This counts as a Verbal Warning, and the escalation procedures shall be followed
as described above in this plan.
2. Inspector documents the discharge and notifies the Development Services Director as soon as
practicable but in no more than 24 hours.
Employee Training:
All applicable employees should be trained in general stormwater pollution prevention, including
how to recognize and report illegal connections and discharges.
Record Keeping and Documentation:
1. Keep a copy of this plan on site.
2. Post signs as to whom to report spills to.
3. Keep a list of all employees trained in the facility’s Stormwater Pollution Prevention binder
or other location.

3. Maintain and Implement a written IDDE Plan to detect and address illicit discharges,
illegal dumping, spills, and any non-stormwater discharges identified as significant
contributors to the MS4.
This includes the periodic evaluation of the program goals and implementation strategies.
Waynesville will evaluate the effectiveness of the IDDE program at least annually and include
this evaluation in our MS4 permit annual report.
In addition to the IDDE program, the Town’s Land Use Map aids in predicting and identifying
illicit discharges (Appendix D). The map divides the land uses into residential of various density,
mixed use, community facilities, and industrial areas. The map is a part of the 2035 Waynesville
Comprehensive Land Use Plan.
4. Provide a mechanism for tracking and documenting each illicit discharge, illicit connection
or illegal dumping event including date(s) reported and/or observed, the results of the
investigation, any follow-up of the investigation, the date the investigation was closed, the
issuance of enforcement actions, and the ability to identify chronic violators.
When a potential illicit discharge is reported by the public or observed during a dry weather
screening, an inspector together with the Public Works crew will visually inspect the nearby
manholes of the storm drain network. Depending on the nature of the discharge, an inspector will
follow it up the stream or along the pipe to track down the source. Water sampling and testing
will be done on an as-needed basis.
The Town uses the Reporting Form, GIS mapping, and IDDE Excel Log to keep track of illicit
discharge complaints and as a mechanism to identify chronic violators.
Initially, an illicit discharge complaint is documented in the Illicit Discharge/Connection
Reporting Form shown on page 16 of this Plan. The form includes the information about the
property, investigator, observed illicit discharge indicators, dates, location, contacts made, and
follow-up actions. The pictures must be attached to the form as well. The records are kept
electronically and in hard copy in the Waynesville Development Services office.
Then, the complaint is logged into the IDDE Excel Log with the information about the PIN of
the property, address, contact, nature of complaint, investigative actions, and links to relevant
case documents. The complaints are investigated promptly following the steps in the SOP for
Illicit Discharges described on page 13 of this Plan, starting with verbal notification, and
escalating to first written notification, second written notification, and legal penalties. The
records are kept electronically and in hard copy in the Waynesville Development Services office.
If a Notice of Violation (NOV) is issued, the Development Services uses a GIS mapping to
register the NOV action. The Development Services Department has created the NOVs map as a
secondary tracking mechanism to identify chronic offenders and areas prone to illicit discharges.
This map provides a good visual coverage of all chronic offenders within our MS4 limits. It

5. Train municipal staff and contractors who, as part of their normal job responsibilities, may
observe an illicit discharge, illicit connection, illegal dumping, or spills. Training shall include
how to identify and report illicit discharges, illicit connections, illegal dumping, and spills.
Each staff training event shall be documented, including the agenda/materials, date, and
number of staff participating.
• The Town is currently developing a training program for the Public Works Department in

pollution prevention, including how to recognize and report illegal connections and
discharges. The first round of training will be starting in winter 2022.
• The Town’s website has a Stormwater page:
https://www.waynesvillenc.gov/departments/development-services/stormwater-management
The Stormwater page contains a good amount of education information about the illicit
discharge by the EPA, NC DEQ, and Center for Watershed Protection.
• The Development Services Department and Haywood Waterways plan to give public
presentations about the stormwater issues, including illicit discharges, and Waynesville
Stormwater Management Plan updates to the Board of Aldermen at least annually. These
presentations are added to the agenda, and they comply with all the public notification
requirements. The first presentation was held on December 14th, 2021. The presentation
materials, topics, minutes, community projects, and related newspaper articles about the
Town’s Stormwater program can be found in the Public Hearings section of the
Stormwater Page. The agendas and minutes are also kept electronically and in hard copy
in the Development Services office.
6. Provide a mechanism for the public and staff to report illicit discharges, illegal dumping,
and spills. The mechanism shall be publicized to facilitate reporting and shall be managed to
provide rapid response by appropriately trained personnel.
The Town Staff will utilize the Illicit Discharge SOP and Form to report illicit discharges, spills,
and dumping. The Town provides a mechanism for the public to report illicit discharge on its
Stormwater page that contains responsible departments (Development Services and Haywood
Waterways), their contact information, and the NC DEQ Stormwater Hotline.

12.5.9 Illicit Discharges and Connections.
A. Illicit Discharges: No person shall cause or allow the discharge, emission, disposal, pouring,
or pumping directly or indirectly to any stormwater conveyance, the waters of the State, or
upon the land in manner and amount that the substance is likely to reach a stormwater
conveyance or the waters of the State unless permitted by an NPDES Permit. However, non-
stormwater discharges associated with the following activities are allowed provided that the
do not significantly impact water quality:
• Filter backwash and draining associated with swimming pools.
• Filter backwash and draining associated with raw water intake screening and filtering devices.
• Condensate from residential or commercial air conditioning.
• Residential vehicle washing.
• Flushing and hydrostatic testing water associated with utility distribution systems.
• Discharges associated with emergency removal and treatment activities, for hazardous
materials, authorized by the federal, state or local government on-scene coordinator.
• Uncontaminated ground water (including the collection or pumping of springs, wells, or rising
ground water and ground water generated by well construction or other construction
activities).
• Collected infiltrated stormwater from foundation or footing drains.
• Collected ground water and infiltrated stormwater from basement or crawl space pumps.
• Irrigation water.
• Street wash water.
• Flows from fire-fighting.
• Discharges from the pumping or draining of natural watercourses or water bodies.
• Flushing and cleaning of stormwater conveyances with unmodified potable water.
• Wash water from the cleaning of the exterior of buildings, including gutters, provided that the
discharge does not pose an environmental or health threat.
21| IDDE Plan, Waynesville, NC, 2022
• Other non-stormwater discharges for which a valid NPDES discharge permit has been
authorized and issued by the U.S. Environmental Protection Agency or by the State of North
Carolina, provided that any such discharges to the municipal separate storm sewer system
shall be authorized by the Town.
• Prohibited substances include but are not limited to: anti-freeze, chemicals, animal waste,
paints, garbage, and litter.
B. Illicit Connections: Connections to a stormwater conveyance or stormwater conveyance
system which allow the discharge of non-stormwater, other than the exclusions described in
subsection 12.5.11.A above, are unlawful. Prohibited connections include, but are not limited
to: industrial/commercial floor drains, wastewater from washing machines or sanitary sewers,
wash water from commercial vehicle washing or steam cleaning, and waste water from septic
systems.
1. Prior Illegal Connections to Cease Within One (1) Year: Where connections exist in
violation of this section and said connections were made prior to the adoption of this
provision or any other ordinance prohibiting such connections, the property owner or the
person using said connection shall remove the connection within one (1) year following
application of this regulation.
2. Hazardous Material Connections to Cease Immediately: The aforementioned one (1) year
grace period shall not apply to connections that result in the discharge of hazardous material.
Nor shall the grace period apply to other discharges which pose an immediate threat to health
and safety, or are likely to result in immediate injury and harm to real or personal property,
natural resources, wildlife or habitat. For such connections, the Public Works Director shall
designate the time within which the connection shall be removed. In setting the time limit for
compliance, the director shall take into consideration: the quantity and complexity of the
work; the consequences of delay; the potential harm to the environment, public health and to
public and private property; and the cost of remedying the damage.
C. Spills: Spills or leaks of polluting substances released, discharged to, or having the potential
to released or discharged to the stormwater conveyance system, shall be contained,
controlled, collected, and properly disposed. All affected areas shall be restored to their
preexisting condition.
Persons in control of the polluting substances immediately prior to their release or discharge,
and persons owning the property on which the substances were released or discharged, shall
immediately notify the Town of Waynesville of the release or discharge, as well as making
any required notifications under state and federal law. Notification shall not relieve any
person of any expenses related to the restoration, loss, damage, or any other liability which
may be incurred as a result of said spill or leak, nor shall such notification relieve any person
from other liability which may be imposed by State or other law.
