2. B. Fraud and false statements. Dischargers making false statements in any submittal, report or other document required by this Chapter or associated rules are subject to the enforcement provisions of this Chapter and any other applicable local and state laws and regulations.

Dischargers subject to this Chapter must maintain and preserve for no fewer than five years any records, books, documents, memoranda, reports, correspondence and document summaries relating to observation, sample collection and analysis conducted in order to comply with this Chapter or associated rules. All records that are the subject of any enforcement or litigation activities brought by the City must be retained and preserved by the discharger until all enforcement activities have concluded and all periods of limitation with respect to any and all appeals have expired.

1. A. Violations. It is a violation for any person to fail to comply with the requirements of this Chapter or associated rules. Each day a violation occurs or continues may be considered a separate violation. BES will hold the person or persons solely responsible for complying with BES enforcement actions. Violations of this Chapter or associated rules include, but are not limited to:
   1. 1. Discharges with any of the attributes of the prohibited discharge list of Section 17.39.040;
   2. 2. Failure to meet any requirement or condition of a BES discharge permit or authorization, including exceedances of a discharge limit, issued under the authority of this Chapter or associated rules;
   3. 3. Failure to comply with a BES discharge permit or authorization-related submittal schedule or a violation remediation schedule;

4. D. Cost recovery. The City Administrator may recover all reasonable costs incurred by the City that are attributable to or associated with violations of this Chapter or associated administrative rules per PPD item ENB-4.15. Failure to pay costs related to a civil penalty or summary abatement within 30 days following a final determination is grounds for permit revocation or termination of the permittee’s discharge
5. E. City summary abatement. To the extent permitted by law, the City Administrator may recover from the person causing the violation all costs incurred by the City to summarily abate the following:
   1. 1. A violation that is not remedied through required corrective actions;
