3 910.00 TOTAL CIVIL PENALTY
106.36 Enforcement Costs
4 016.36 TOTAL AMOUNT DUE
Pursuant to G.S. 143-215.6A(c), in determining the amount of the penalty I have taken into account the Findings of Fact and
Conclusions of Law and the factors set forth at G.S. 143B-282.I (b), which are:
(1) The degree and extent of harm to the natural resources of the State, to the public health, or to 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 noncompliance;
(6) Whether the violation was committed willfully or intentionally;
(7) The prior record of the violator in complying or failing to comply with programs over which the Environmental
Management Commission has regulatory authority; and
(8) The cost to the State of the enforcement procedures.

Within thirty (30) days of receipt of this notice, you must do one of the following:
(1) Submit payment of the penalty, OR
(2) Submit a written request for remission, OR
(3) Submit a written request for an administrative hearing
Option 1: Submit payment of the penalty:
Payment should be made directly to the order of the Department of Environmental Quality (do not inchide waiver
form). Payment of the penalty will not foreclose further enforcement action for any continuing or new violation(s).
Please submit payment to the attention of:
Wastewater Branch
Division of Water Resources
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
Option 2: Submit a written request for remission or mitigation including a detailed justification for such
request:
Please be aware that a request for remission is limited to consideration of the five factors listed below as they may
relate to the reasonableness of the amount of the civil penalty assessed. Requesting remission is not the proper
procedure for contesting whether the violation(s) occurred or the accuracy of any of the factual statements contained in
the civil penalty assessment document. Because a remission request forecloses the option of an administrative hearing,
such a request must be accompanied by a waiver of your right to an administrative hearing and a stipulation and
agreement that no factual or legal issues are in dispute. Please prepare a detailed statement that establishes why you
believe the civil penalty should be remitted, and submit it to the Division of Water Resources at the address listed below.
In determining whether a remission request will be approved, the following factors shall be considered:
(1) whether one or more of the civil penalty assessment factors in NCGS 14313-282.1(b) was wrongfully
applied to the detriment of the petitioner;
(2) whether the violator promptly abated continuing environmental damage resulting from the violation;
(3) whether the violation was inadvertent or a result of an accident;
(4) whether the violator had been assessed civil penalties for any previous violations; or
(5) whether payment of the civil penalty will prevent payment for the remaining necessary remedial actions.
Please note that all evidence presented in support of your request for remission must be submitted in writing. The
Director of the Division of Water Resources will review your evidence and inform you of his decision in the matter of
your remission request. The response will provide details regarding the case status, directions for payment, and
provision for further appeal of the penalty to the Environmental Management Commission's Committee on Civil Penalty
Remissions (Committee). Please be advised that the Committee cannot consider information that was not part of the
original remission request considered by the Director. Therefore, it is very important that you prepare a complete and
thorough statement in support of your request for remission.
In order to request remission, you must complete and submit the enclosed "Request for Remission of Civil Penalties,
Waiver of Right to an Administrative Hearinl;, and Stipulation of Facts" form within thirtX (30) days of receipt of this
notice. The Division of Water Resources also requests that you. complete and submit the enclosed "Justification for
Remission Request."
Both forms should be submitted to the following address:
Wastewater Branch
Division of Water Resources
1617 Mail Service Center
Raleigh, North Carolina 27699-1617

Option 3: File a petition for an administrative hearing with the Office of Administrative Hearings:
If you wish to contest any statement in the attached assessment document you must file a petition for an administrative
hearing. You may obtain the petition form from the Office of Administrative Hearings. You must file the petition with
the Office of Administrative Hearings within thirty (30) days of receipt of this notice. A petition is considered filed

In looking back through the data, the only explanation, I have for the parameters being exceeded is that we
are still receiving slug loads of Iron from the Towns WTP, which inhibit the biological treatment. We will continue
to work with the WTP to resolve these issues to prevent these parameters from continuing to be violated. The WTP
will soon have the actiflow unit online and we are hopeful that this will help with the slug loads we are currently
seeing. We are also still working with Synagro to ensure that the solids are getting removed from the WTP's lagoon
to help reduce th amount of Iron that gets released to the WWTP.
Sincerely.

A Notice of Violation/Intent to Issue Civil Penalty is being issued for the noted violation of North Carolina General
Statute (G.S.) 143-215.1 and the facility's NPDES WW Permit. Pursuant to G.S. 143-215.6A, a civil penalty of
not more than twenty-five thousand dollars ($25,000.00) may be assessed against any person who violates or
fails to act in accordance with the terms, conditions, or requirements of any permit issued pursuant to G.S.
143-215.1.

discuss overall compliance please respond in writing within ten (10) business days after receipt of this Notice. A
review of your response will be considered along with any information provided on the submitted Monitoring
Report(s). You will then be notified of any civil penalties that may be assessed regarding the violations. If no
response is received in this Office within the 10-day period, a civil penalty assessment may be
prepared.
Remedial actions should have already been taken to correct this problem and prevent further occurrences in the
future. The Division of Water Resources may pursue enforcement action for this and any additional violations of
State law. If the violations are of a continuing nature, not related to operation and/or maintenance problems,
and you anticipate remedial construction activities, then you may wish to consider applying for a Special Order by

Reminder: Pursuant to Permit Condition 6 in Section E the Permittee is required to verbally notify the Regional
