NAME OF POTW Enforcement Response Plan (ERP)
1. Introduction
It is the responsibility of the City of Lenoir Gunpowder Creek WWTP NCO023736 to enforce all applicable
Federal, State, and local pretreatment regulations. These regulations are outlined in Federal regulation
40 CFR 403 and State regulation 15A NCAC 2H .0900, and the local SUO. This Enforcement
Response Plan (ERP) has been established as an element of the POTW's pretreatment program. The
purpose of the ERP is to provide for fair and equitable treatment of all Users for anticipated enforcement
situations. In general, enforcement actions will be taken in accordance with this enforcement Response
Plan. However, the enforcement actions available are not exclusive (NC Model SUO Section
8.4). Therefore, any combination of the enforcement actions can be taken against a non -compliant user.
Enforcement actions taken in response to the requirements of 40 CFR Part 441 will be taken/decided on a
case -by -case basis.
2. Enforcement Actions Available to the POTW
The Director of the POTW is empowered through North Carolina General Statute (NCGS) 143-215.6A and the
local Sewer Use Ordinance (SUO) to take a wide variety of enforcement actions. The following is a list of those
actions and the corresponding section of the local SUO that describes each. Corresponding sections from the
NC model SUO are listed as well.

Civil Penalties 8.2
Injunctive Relief 8.3(b)
Water Supply Severance 8.3(c)
In addition to the actions listed above, a User who violates the provisions of NCGS 143-215.613 may be
referred by the Director to the District Attorney for possible criminal prosecution.
In determining the amount of civil penalties for a particular violation the Director shall consider the following
factors (NC model SUO section 8.2)
1. The degree and extent of the harm to the natural resources, to the public health, or to public
or private property resulting from the violation;
2. The duration and gravity of the violation;
3. The effect on ground or surface water quantity or quality or on air quality;
4. The cost of rectifying the damage;
5. The amount of money saved by non-compliance;
6. Whether the violation was committed willfully or intentionally;
7. The prior record of the violator in complying or failing to comply;
8. The costs of enforcement to the POTW.
Adjudicatory hearing procedures regarding permit decisions, civil penalties, and administrative orders may be
found in the SUO (NC Model SUO Section 10).
3. Investigation of Noncompliance
The Staff of the POTW will generally investigate User compliance with permits or the provisions of the SUO in
three ways:
1. on -site inspections of the User to include scheduled and unscheduled visits;
2. scheduled and unscheduled sampling of the User's effluent, alone or in conjunction with other
Users' effluents;
3. review of self -monitoring data, if required, from the User.
The compliance status of Significant Industrial Users will be evaluated at a minimum once every 6 months.
4. Types of Violations
The following is a list of different types of violations, by category. This list is not inclusive but serves as a
general list of anticipated types of noncompliance. The User's permit, local SUO, and State and Federal
regulations serve as additional references for pretreatment requirements.
Unpermitted Discharges. Users are responsible for obtaining and renewing permits, if required.
Modeled after Comprehensive Guide, Chapter 8: ERP Page: 4
Appendix 8-A, revised June 2008; June 2019

Permit Limits. Users are responsible for maintaining compliance with all effluent limits. The POTW will
evaluate the extent of the limits violation(s). In determining the extent of violation(s), Significant Non -
Compliance (SNC) as defined by State and EPA regulations will be determined.
Self -Monitoring Violations. A User who fails to adequately conduct all the monitoring required in the permit,
including monitoring frequencies and sampling methods specified, is in violation. This includes a User who
does not resample per their permit when a limit violation occurs.
Reporting Violations. A User who fails to provide information (e.g. self monitoring reports) required in their
Permit or the SUO in the required time frame is in violation. Late or incomplete reports will also be
considered violations. A SIU who submits a report more than 30 days late is possibly considered in SNC.
Permit Conditions. Failure to apply or reapply for a permit is considered a violation. Users who violate the
general or other conditions (e.g. slug loading, dilution prohibition) outlined in their permits or the SUO shall be
considered to be in violation.
Enforcement Orders. Failure to meet the requirements of an order (e.g. interim limits, milestone dates),
whether the order was entered into voluntarily or mandated by the POTW, shall be considered a violation.
Missing a scheduled compliance milestone by more than 90 days is considered SNC.
S. Responses: Timeframes, Responsible Officials, Escalated Actions.
The attached chart further outlines types of violations and specifies POTW actions (initial and escalated),
timeframes, and the officials responsible for completing the actions. This chart shall be considered a part of
the Enforcement Response Plan.
Responses to violations affecting the operation of the POTW, resulting in POTW NPDES violations, or resulting
in environmental harm or endangerment to human health will be taken immediately or as soon as possible
following discovery.
A User may be sent a Notice of Violation (NOV) or Notice of Noncompliance (NNC) for each individual
violation. Alternatively, violations over a period of time may be summarized. In general, NOVs in response to
violations will be issued within 30 days of discovery of the violations. Users found to be in SNC for two (2)
consecutive 6-month periods will be issued an enforceable order to return to compliance. In all cases,
escalated or continuing enforcement action will be taken against Users who do not return to compliance in a
timely manner.
Cases of falsifying reports, tampering with monitoring or sampling equipment, or otherwise preventing the
collection of representative data may be referred to the District Attorney for possible criminal investigation.
Show cause hearings may be held at the Director's discretion prior to taking enforcement actions.
