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
Divisibn of Water Quality at the address listed below. In determining whether a remission request
will be approved, the following factors, shall be considered:
(1) one or more of the civil penalty assessment factors in G.S. 143B-282. I (b) were wrongfully
applied to the detriment of the petitioner;
(2) the violator promptly abated continuing environmental datnage resulting from the violation;
(3) the violation was inadvertent or a result of an accident;
(4) the violator had been assessed civil penalties for any previous violations;
(S) 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 the Division of Water Quality will review your evidence and infortri 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

to identify the causative agents of effluent toxicity, isolate the sources of toxicity, evaluate the effectiveness of toxicity
control options, and confirm reductions in effluent toxicity. Please be aware that North Carolina General Statutes provide
for assessment of civil penalties for violations of NPDES permit limitations and requirements.
The reverse side of this Notice contains important inforniation concerning your of Effluent Toxicity
Monitoring and Reporting Requirements. Please note appropriate mailing addresses for submitting your Discharge
Monitoring Reports (DMRs) and Aquatic Toxicity, (AT) Test Forms, We encourage you to review this information; if it
would be helpful, to discuss this situation or possible solutions to resolve effluent toxicity noncompliance,'please contact
me or Mr. Kevin Bowden with this office at [phone].
