Dear Mr. Robbins:
This letter transmits a Notice of Violation and assessment of civil penalty in the amount of $536.57 ($500.00 civil penalty

This assessment is based upon the following facts: a review has been conducted of the Discharge Monitoring Report

Based upon the above facts, I conclude as a matter of law that Town of Benson violated the terms, conditions or

Attachment A. In accordance with the maximums established by G.S. 143-215.6A(a)(2), a civil penalty may be assessed
against any person who violates the terms, conditions or requirements of a permit required by G.S. 143-215.1(a).

$500.00 TOTAL CIVIL PENALTY
$36.57 Enforcement Costs
$536.57 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-282.1(b), which are:
(1)
(2)
(3)
(4)
(5)
(6)
(7)
(8)
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;
The duration and gravity of the violation;
The effect on ground or surface water quantity or quality or on air quality;
The cost of rectifying the damage;
The amount of money saved by noncompliance;
Whether the violation was committed willfully or intentionally;
The prior record of the violator in complying or failing to comply with programs over which the Environmental
Management Commission has regulatory authority; and
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 include 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 Iimited 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 143B-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 Hearin and i ulation of Facts" form within thirty (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
when it is received in the Office of Administrative Hearings during normal office hours. The Office of Administrative
Hearings accepts filings Monday through Friday between the hours of 8:00 a.m. and 5:00 p.m., except for official state
holidays. The petition may be filed by facsimile (fax) or electronic mail by an attached file (with restrictions) - provided
the signed original, one (1) copy and a filing fee (if a filing fee is required by NCGS §150B-23.2) is received in the
Office of Administrative Hearings within seven (7) business days following the faxed or electronic transmission. You

Mr. William F. Lane, General Counsel
Department of Environmental Quality
1601 Mail Service Center
Raleigh, North Carolina 27699-1601
Please indicate the case number (as found on page one of this letter) on the petition.
Failure to exercise one of the options above within thirty (30) days of receipt of this letter, as evidenced by an internal
date/time received stamp (not a postmark), will result in this matter being referred to the Attorney General's Office for
collection of the penalty through a civil action. Please be advised that additional penalties may be assessed for violations
that occur after the review period of this assessment.

statements contained in the civil penalty assessment document. Pursuant to N.C.G.S. § 143B-282.1(c), remission of a civil
penalty may be granted only when one or more of the following five factors apply. Please check each factor that you

(b) the violator promptly abated continuing environmental damage resulting from the violation (i.e., explain the
steps that you took to correct the violation and prevent future occurrences);

something you could not prevent or prepare for);

3. Total Nitrogen Load is the mass quantity of Total Nitrogen (TN) discharged in a given period of time and
requires Total Monthly Flow (TMF). See condition A. (3.). Calculation of Total Nitrogen Loads.
4. The monthly average effluent BOD5 and Total Suspended Residue concentrations shall not exceed 15%
of the respective influent value (85% removal).
5. Total Residual Chlorine compliance is required if chlorine or chlorine derivative is used for disinfection.
The Division shall consider all effluent TRC values reported below 50 ug/1 to be in compliance with the
permit. However, the Permittee shall continue to record and submit all values reported by a North
Carolina certified laboratory (including field certified), even if these values fall below 50 ugll.
6. For a given wastewater sample, Total Nitrogen (TN) = TKN + (NO3-N + NO2-N) where TKN is Total
Kjeldahl Nitrogen, and (NO3-N + NO2-N) is Nitrate and Nitrite Nitrogen.
7. Compliance with this limit shall be determined in accordance with conditions A. (4.) Annual Limits for
Total Nitrogen. and A. (5.) Total Nitrogen Allocations.
8. The quarterly average for total phosphorus shall be the average of composite samples collected weekly
during the calendar quarter (January -March, April -June, July -September, October -December).
9. Monitoring for Nickel shall be conducted in conjunction with the Chronic Toxicity monitoring.
10. Chronic Toxicity (Ceriodaphnia dubia) P/F at 90%: January, April, July, and October [see
condition A. (2.)]. Toxicity monitoring shall coincide with metals monitoring.
11. The permittee shall perform three Effluent Pollutant Scans during the term of this permit [see A.
(7.)].
12. Effluent Total Hardness sampling shall be performed in conjunction with testing for hardness -
dependent metals (cadmium, copper, lead, nickel, silver, and zinc).
13. The permittee shall sample instream hardness upstream of the facility's discharge. The sample
shall be representative of the hardness in the receiving stream. If the permittee is a member of a
monitoring coalition program, sampling for instream hardness may be waived as long as the
monitoring coalition agrees to sample hardness at the nearest upstream location, at a minimum
frequency of quarterly, and the permittee has obtained approval from DWR-NPDES Permitting
Unit that the upstream station being monitored by the Coalition is representative of the receiving
stream for this discharge. The permittee is responsible for submitting instream hardness test
results with its permit renewal application package. If Coalition membership is cancelled or the
Coalition terminates instream hardness sampling at the approved station, the permittee will
immediately notify the Division and resume sampling for instream hardness upstream of its
discharge.
14. 2/week sampling must occur on any two non-consecutive days during the calendar week.
There shall be no discharge of floating solids or visible foam in other than trace amounts.
