that may affect the Division's enforcement response, please include that information as part of

construction activities, you may wish to consider applying for a Special Order by Consent (SOC). Please be aware
that it is a condition of your NPDES permit that you adequately address such violations (Part II, Section B. 2 -
the"Duty to Mitigate" condition). Violations of a continuing nature can justify the assessment of increased civil
penalty amounts to address the noncompliance.

compliance, or explore the possibility of entering into a SOC, please contact Donald Smith of the Raleigh Regional
