A Notice of Violation/Intent to Issue Civil Penalty is being issued for the noted violation of North Carolina General

not more than twenty-five thousand dollars ($25,000.00) may be assessed against any person who violates or

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
