City staff may, on an informal basis, take action against a discharger for minor violations or technical or clerical shortcomings of a user or user's compliance submittals. These informal administrative actions may include informal notices (i.e., telephone calls to the user's representative), notice of violation (NOV), and informal meetings or informal warning letters. Such action will not prevent a subsequent or concurrent imposition of other enforcement mechanisms. (Ord. 01-102 § 2(part), 2001).
