Illicit Discharge Detection and Elimination Program Plan
Bruce Oakley
Town Manager
An Illicit discharge means any discharge to a town separate storm sewer that is not composed entirely of
stormwater except discharge pursuant to a NPDES permit (other than the NPDES permit for discharge from
the town separate storm sewer) and discharges resulting from firefighter activities. The intention of this plan
is to aid in identification of any illicit discharges into the stormwater system, ensure proper action is taken
and subsequent elimination of the discharge.
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, any liquid, solid, gas, or
other substance, other than stormwater; provided that non-stormwater discharges associated with the
following activities are allowed and provided that they do not significantly impact water quality:
a. Water line flushing;
b. Landscape irrigation;
c. Diverted stream flows;
d. Rising ground waters;
e. Uncontaminated ground water infiltration (as defined at 40 CFR 35.2005(20));
f. Uncontaminated pumped ground water;
g. Discharges from potable water sources;
h. Foundation drains;
i. Air conditioning condensation;
j. Irrigation water;
k. Springs;
I. Water from crawl space pumps;
m. Footing drains;
n. Lawn watering;
o. Individual residential car washing;
p. Flows from riparian habitats and wetlands;
q. Dechlorinated swimming pool discharges;

Yard waste piled for removal, and debris placed for roadside pickup, provided it was placed at least
five feet from any defined stormwater conveyance (ditch, curb, pipe, etc) and all prohibited
substances listed in subsection (a)(2) of this section are contained in a manner to prevent them
from being transported by stormwater flows;
Street wash water;
Pumping down of Carolina Beach Lake as permitted by state agencies;
Other nonstormwater discharges for which a valid NPDES discharge permit has been approved
and issued by the state, and 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: oil, antifreeze, chemicals, animal waste, paints,
garbage, and litter.
Illicit connections:
(1) Connections to a stormwater conveyance or stormwater conveyance system that allow the discharge
of non-stormwater, other than the exclusions described in subsection (a)(1) of this section, are unlawful.
Prohibited connections include, but are not limited to: floor drains, waste water from washing machines
or sanitary sewers, wash water from commercial vehicle washing or steam cleaning, and waste water
from septic systems.
(2) Where such connections exist in violation of this plan and said connections were made prior to the
adoption of the ordinance from which this plan is derived or any other ordinance prohibiting such
connections, the property owner or the person using said connection shall remove the connection within
one year following the effective date of the ordinance from which this plan is derived. However, the one-
year grace period shall not apply to connections which may result in the discharge of hazardous
materials or 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.
(3) a. Where it is determined that said connection:
1. May result in the discharge of hazardous materials or may pose an immediate threat to health
and safety, or is likely to result in immediate injury and harm to real or personal property,
natural resources, wildlife, or habitat; or
2. Was made in violation of any applicable regulation or ordinance, other than this plan; the Town
Manager or his designee shall designate the time within which the connection shall be
removed.
b. In setting the time limit for compliance, the Town Manager or his designee shall take into
consideration:
1. The quantity and complexity of the work;
2. The consequences of delay;
3. The potential harm to the environment, to the public health, and to public and private property;
and
4. The cost of remedying the damage.
Spills:
(1) 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 pre-existing condition.
(2) 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 Fire Chief 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.
Nuisance:
Illicit discharges and illicit connections which exist within the town are hereby found, deemed, and declared
to be dangerous or prejudiced to the public health or public safety and are found, deemed, and declared to
be public nuisances. Such public nuisances shall be abated in accordance with the procedures set forth in
this plan.
Violations, penalties and enforcement.
The following is taken from Sec. 32-261 of the Town of Carolina Each Stormwater Ordinance: Any of the
following violations shall subject the offender to a civil penalty for the initial violation and a civil penalty for
each subsequent violation, each pursuant to the town's annually adopted rate and fee schedule; or the full
amount of penalty to which the town is subject for violations of the Phase II stormwater permit directly caused
by the offender. The offender may also be imprisoned for not more than 30 days, or both, at the discretion
of the court. Each day that a violation continues after the offender has been notified of the violation shall
constitute a separate and distinct offense.
(1) The violation of any provision of this chapter or of any rule or regulation, by whatever name, issued or
adopted pursuant to the provisions of this chapter.
(2) The failure to comply with the express or implied condition or term of any permit issued or agreement
executed pursuant to the provisions of this chapter.
(3) The failure to comply with any order, notice, or directive of the Town Manager or his designee to stop
work or to take corrective action.
(4) The failure of the owner of, or any person responsible for the maintenance of, any property served by
an existing private on -site stormwater BMP to maintain said BMP in proper working order.
(5) If the offender fails to pay this penalty within ten days after being cited for a violation, the penalty may
be recovered in a civil action in the nature of debt.
The town may seek to enforce this chapter or to prevent, restrain, correct or abate violations of this chapter
through any appropriate equitable action.
The town may seek to enforce this chapter by using any one or any combination of the foregoing remedies.
No building permit shall be issued for any building without approval of the storm drainage BMPs for the
property and buildings by the Town Manager or his designee.
In case of any violation of this chapter, the Town Manager or his designee or other appropriate official shall
take action to put an end to such violation.
Identification of Illicit Discharges
The first step for detecting non-stormwater connections is to physically observe all discharge points in the
field during periods of dry weather.
Visual inspections for illicit discharges must occur during dry weather conditions. Dry weather conditions
are defined as a minimum of 24 consecutive hours with less than 0.10 inches of rainfall, however 72 hours
is recommended. Stormwater outfalls are designed to only carry stormwater runoff; therefore if a flow
exists at a discharge point during the dry weather inspections, it is identified as a potential illicit discharge.
Stormwater discharges to culverted streams that cannot be easily accessed (i.e., underground discharge
locations) should be inspected at the nearest upstream location (e.g., manhole). It may be possible for
inspection to take place inside the culverted stream depending on the size of pipes, typically handed
through CCty visual inspection.

Dry weather flow can be continuous or intermittent. Therefore, it is important to accurately document
outfall conditions and evaluate whether future inspections are needed based on known water quality
problems or impaired water bodies. In cases where there is physical evidence of an intermittent flow or
illicit discharge, follow-up inspections should be performed to identify the dry weather flow. Intermittent
flows also present an opportunity to involve the public with outfall observations.
Observations: During inspection of an outfall for the presence of dry weather flow, physical
characteristics such as odor, color, sheen, floatables, turbidity, the condition of the outfalls, and
surrounding land uses and activities will be observed for further identification and confirmation of illicit
discharges. As most of the Town's outfalls are tidally impacted or submerged, personnel should inspect
the nearest accessible upstream catch basin or manhole. Any suspected illicit discharges should be
handed in the manner aforementioned.
Infrastructure Improvement Programs: The Town has recently implemented a Phased Infrastructure
Improvement Program to address all deficiencies or needed improvements in regards to Stormwater,
Water and Sewer Utilities. Throughout the previous and forthcoming phases of improvement, any
exposed and identified illicit discharges have been and shall be eliminated through a proper course of
action.
Stormwater Vactor Activities: Through the routine maintenance and cleaning of the Town stormwater
system, the vactor operation crew shall inspect and monitor for any illicit discharges. Camera equipment
may be needed to identify exact and type of illicit connection.
Illicit Discharge Concerns Submitted Externally: Upon receipt of a service request regarding a
suspected illicit discharge, submitted either through email, phone call, or the Town web portal, Staff shall
inspect the area of concern. Proper course of action should be taken as necessary.
Staff Training: Town Stormwater staff shall be trained to properly identify illicit discharges and the
subsequent actions to take upon a confirmed identification of said discharge.
