Section 8 – Suspension of MS4 Access

8.1 The Public Works Department may, without prior notice, suspend MS4 discharge access to a person when such suspension is necessary to stop an actual or threatened discharge which presents or may present imminent and substantial danger to the environment, or to the health or welfare of persons, or to the MS4 or Waters of the United States. If the violator fails to comply with a suspension order issued in an emergency, the authorized enforcement agency may take such steps as deemed necessary to prevent or minimize damage to the MS4 or Waters of the United States, (as locally defined within the jurisdiction of the City of Prescott) or to minimize danger to persons.

8.2 Any person discharging to the MS4 in violation of this Code may have their MS4 access terminated if such termination would abate or reduce an illegal discharge. The authorized enforcement agency will notify a violator of the proposed termination of its MS4 access. The violator may petition the authorized enforcement agency for a reconsideration and hearing.

8.3 A person commits an offense if the person who has been suspended under this section reinstates MS4 access to premises terminated pursuant to this Section, without the prior approval of the authorized enforcement agency.

Section 9 – Industrial or Construction Activity Discharges

Any person subject to an industrial or construction activity NPDES storm water discharge permit shall comply with all provisions of such permit. Proof of compliance with said permit may be required in a form acceptable to the Public Works Department prior to the allowing of discharges to the MS4.

Section 10 – Monitoring of Discharges

10.1 Applicability – This section applies to all facilities that have storm water discharges associated with industrial activity, including construction activity.

10.2 Access to Facilities.

1. The Public Works Department shall be permitted to enter and inspect facilities subject to regulation under this Code as often as may be necessary to determine compliance with this Code. If a discharger has security measures in force which require proper identification and clearance before entry into its premises, the discharger shall make the necessary arrangements to allow access to representatives of the authorized enforcement agency.

2. Facility operators shall allow the Public Works Department ready access to all parts of the premises for the purposes of inspection, sampling, examination and copying of records that must be kept under the conditions of an NPDES permit to discharge storm water, and the performance of any additional duties as defined by state and federal law.

3. The Public Works Department shall have the right to set up on any permitted facility such devices as are necessary in the opinion of the authorized enforcement agency to conduct monitoring and/or sampling of the facility’s storm water discharge.

4. The Public Works Department has the right to require the discharger to install monitoring equipment as necessary. The facility’s sampling and monitoring equipment shall be maintained at all times in a safe and proper operating condition by the discharger at its own expense. All devices used to measure stormwater flow and quality shall be calibrated to ensure their accuracy.

5. Any temporary or permanent obstruction to safe and easy access to the facility to be inspected and/or sampled shall be promptly removed by the operator at the written or oral request of Public Works Department and shall not be replaced. The costs of clearing such access shall be borne by the operator.

6. Unreasonable delays in allowing the Public Works Department access to a permitted facility is a violation of a storm water discharge permit and of this Code. A person who is the operator of a facility with a NPDES permit to discharge storm water associated with industrial activity commits an offense if the person denies the authorized enforcement agency access to the permitted facility for the purpose of conducting any activity authorized or required by this Code.

7. If the Public Works Department has been refused access to any part of the premises from which stormwater is discharged, and he/she is able to demonstrate probable cause to believe that there may be a violation of this Code, or that there is a need to inspect and/or sample as part of a routine inspection and sampling program designed to verify compliance with this Code or any order issued hereunder, or to protect the overall public health, safety, and welfare of the community, then the authorized enforcement agency may seek issuance of a search warrant from any court of competent jurisdiction.

Section 11 – Requirements to Prevent, Control, and Reduce Storm Water Pollutants by the Use of Best Management Practices

11.1 Public Works Department will adopt regulations identifying Best Management Practices for any activity, operation, or facility which may cause or contribute to pollution or contamination of storm water, the storm drain system, or waters of the U.S.

11.2 The owner or operator of a commercial or industrial establishment shall provide, at their own expense, reasonable protection from accidental discharge of prohibited materials or other wastes into the municipal storm drain system or watercourses through the use of these structural and non-structural BMPs. Further, any person responsible for a property or premise, which is, or may be, the source of an illegal discharge, may be required to implement, at said person’s or entities expense, additional structural and non-structural BMPs to prevent the further discharge of pollutants to the municipal separate storm sewer system.

11.3 Compliance with all terms and conditions of a valid NPDES permit authorizing the discharge of storm water associated with industrial activity, to the extent practicable, shall be deemed compliance with the provisions of this section. These BMPs shall be part of a stormwater pollution prevention plan (SWPPP) as necessary for compliance with requirements of the NPDES permit.

Section 12 – Watercourse Protection

12.1 Every person owning property through which a watercourse passes, or such person’s lessee (persons or entities leasing property, shall keep and maintain that part of the watercourse within the property free of trash, debris, excessive vegetation, and other obstacles that would pollute, contaminate, or significantly retard the flow of water through the watercourse.

12.2 In addition, the owner or lessee shall maintain existing privately owned structures within or adjacent to a watercourse, so that such structures will not become a hazard to the use, function, or physical integrity of the watercourse.

Section 13 – Notification of Spills

13.1 Notwithstanding other requirements of law, as soon as any person responsible for a facility or operation, or responsible for emergency response for a facility or operation who has information of any known or suspected release of materials which are resulting or may result in illegal discharges or pollutants discharging into storm water, the storm drain system, or water of the U.S. or local waterway depicted in said person shall take all necessary steps to ensure the discovery, containment, and cleanup of such release.

13.2 In the event of such a release of hazardous materials said person shall immediately notify emergency response agencies of the occurrence via emergency dispatch services. For purposes of this section, emergency dispatch services shall mean City of Prescott Regional Community Center, (928)
