The purpose of this chapter is to comply with the requirements of the U.S. EPA’s National Pollutant Discharge Elimination System (“NPDES”) permit program (the “Program”) administered by the Iowa Department of Natural Resources (IDNR) by adopting and enforcing regulations regarding illicit discharge to the City’s storm sewer system. The City shall fund operations under this chapter entirely by charges imposed on the owners of properties which are made subject to the Program by virtue of State and Federal law, and/or other sources of funding established by separate ordinance.
The City has obtained a permit for the discharge of storm water from a Municipal Separate Storm Sewer System (MS4 permit) from the IDNR. Said permit is on file at the Stormwater Utility office and is available for public inspection during regular office hours.
(Ord. 1798 – Apr. 14 Supp.)
Terms used in this chapter have the meanings specified in the Program. As used in this chapter, the following terms are defined:
1. An “illicit connection” to the City’s storm sewer system is any physical connection or other topographical or other condition, natural or artificial, which is not specifically authorized by ordinance or written rule of the City, which causes or facilitates, directly or indirectly, an illicit discharge.
2. "Municipal separate storm sewer system" or "MS4" means the conveyance or system of conveyances including storm sewers, roadways, roads with drainage systems, catch basins, curbs, gutters, ditches, constructed channels and storm drains owned or operated by the City of Ankeny.
(Ord. 1661 - Jul. 10 Supp.)
3. "Property" includes but is not limited to real estate, fixtures, facilities, and premises of any kind located upon, under, or above the real estate.
4. "Responsible party" means one or more persons that control or are in possession of or own property. Responsible parties shall be jointly and severally responsible for compliance with this chapter and jointly and severally liable for any illicit discharge from the property controlled, possessed, or owned.
1. Nothing in this chapter shall be deemed to relieve a responsible party subject to an IDNR-issued industrial discharge permit or any other Federal, State or City permit, statute, ordinance or rule from any obligation imposed by such permit, statute, ordinance, or rule if any such obligation is greater than any obligation imposed by this chapter.
2. Any discharge into the City’s storm sewer system prohibited by the City’s MS4 permit, the terms of which are hereby incorporated by reference, shall be deemed an “illicit discharge” in violation of this chapter.
3. Sediment pollution originating from excessive erosion rates on a construction site or sediment pollution entering a municipal storm sewer that causes a water quality violation as determined by the IDNR shall be deemed an illicit discharge in violation of this chapter.
4. The following discharges are not authorized and shall be deemed an illicit discharge in violation of this chapter.
A. Floor drains directed to the storm water system shall be considered discharges even if no actual pollutants are observed entering the system from such a source.
B. Solvents; detergents or other surfactants; and spills or leaks of toxic or hazardous materials; fertilizers; pesticides; and waste products such as ashes, slag and sludge.
C. Solid waste, litter, animal waste and landscape waste, including significant quantities of leaves and grass clippings deposited or placed along streams, ponds, channels, or on sidewalks, street right of ways or other public property subject to runoff or otherwise discharged to the storm water system.
(Ord. 1661 - Jul. 10 Supp.)
The construction, use, maintenance, or continued existence of any illicit connection shall constitute a violation of this chapter. This prohibition expressly includes, without limitation, illicit connections made in the past, regardless of whether the connection was permissible under law or practices applicable or prevailing at the time of connection.
Any responsible party subject an industrial NPDES discharge permit issued by the IDNR shall comply with all provisions of such permit. Proof of compliance with said permit may be required in a form acceptable to the enforcement officer prior to discharges to the storm sewer system authorized by said permit.
1. All detection activities permitted under this chapter shall be conducted by the City Public Works Director, herein referred to as the “enforcement officer.”
(Ord. 1798 – Apr. 14 Supp.)
2. The City shall not be responsible for the direct or indirect consequences to persons or property of an illicit discharge, or circumstances which may cause an illicit discharge, undetected by the City.
3. Every responsible party has an absolute duty to monitor conditions on property owned or controlled by them, to prevent all illicit discharges, and to report to the enforcement officer illicit discharges which the responsible party knows or should have known to have occurred. Failure to comply with any provision of this chapter is a violation of this chapter.
A. Notwithstanding other requirements of law, as soon as any responsible party has information of any known or suspected illicit discharge, the responsible party shall immediately take all necessary steps to ensure the discovery, containment, and cleanup of such discharge at the responsible party’s sole cost.
B. If the illicit discharge consists of hazardous materials, the responsible party shall also immediately notify emergency response agencies of the occurrence via emergency dispatch services.
C. If the illicit discharge emanates from a commercial or industrial establishment, the owner or operator of such establishment shall also retain an on-site written record of the discharge and the actions taken to prevent its recurrence. Such records shall be retained for at least three years.
D. A report of an illicit discharge shall be made in person or by phone or facsimile or email to the enforcement officer immediately but in any event within twenty-four (24) hours of the illicit discharge; notifications in person or by phone shall be confirmed by written notice addressed and mailed or emailed to the enforcement officer within twenty-four (24) hours of the personal or phone notice.
4. Any person or entity shall also report to the City any illicit discharge or circumstances which such person or entity reasonably believes pose a risk of an illicit discharge.
5. Upon receiving a report pursuant to the previous subsections, or otherwise coming into possession of information indicating an actual or imminent illicit discharge, the enforcement officer shall conduct an inspection of the site as soon as reasonably possible and thereafter shall provide to the responsible party, and any third party reporter, a written report of the conditions which may cause or which have already caused an illicit discharge. The responsible party shall immediately commence corrective action or remediation and shall complete such corrective action or remediation within twenty-four (24) hours, or as otherwise directed by the enforcement officer.
(Ord. 1661 - Jul. 10 Supp.)
6. The enforcement officer shall be permitted to enter and inspect property subject to regulation under this chapter as often as is necessary to determine compliance. If a responsible party has security measures that require identification and clearance before entry to its property or premises, the responsible party shall make the necessary arrangements to allow access by the enforcement officer. By way of specification but not limitation:
A. A responsible party shall allow the enforcement officer ready access to all parts of the property for purposes of inspection, sampling, examination and copying of records related to a suspected, actual, or imminent illicit discharge, and for the performance of any additional duties as defined by State and Federal law.
B. The enforcement officer shall have the right to set up on any property such devices as are necessary in the opinion of the enforcement officer to conduct monitoring and/or sampling related to a suspected, actual or imminent illicit discharge.
C. The enforcement officer shall have the right to require any responsible party at responsible party’s sole expense to install monitoring equipment and deliver monitoring data or reports to the enforcement officer as the enforcement officer directs. The sampling and monitoring equipment shall be maintained at all times in a safe and proper operating condition by the responsible party at responsible party’s sole expense. All devices shall be calibrated to ensure their accuracy.
D. Any temporary or permanent obstruction to safe and easy access to property to be inspected and/or sampled shall be promptly removed by the responsible party at the written or oral order of the enforcement officer and shall not be replaced. The costs of clearing such access shall be borne by the responsible party.
E. An unreasonable delay in allowing the enforcement officer access to a property is a violation of this chapter.
F. If the enforcement officer has been refused access to any part of the property from an illicit connection and/or illicit discharge to a municipal storm sewer is occurring, suspected or imminent, and is able to demonstrate probable cause to believe that there may be a violation of this chapter, 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 chapter or any order issued hereunder, or to protect the overall public health, safety, and welfare of the community, then the enforcement officer may seek issuance of a search warrant from any court of competent jurisdiction.
7. If it is determined that an illicit discharge is imminent or has occurred, the actual administrative and remediation costs incurred by the City in the enforcement of this chapter shall be recovered from the responsible party. The enforcement officer shall submit an invoice to the responsible party reflecting the actual costs and wages and expenses incurred by the City for the enforcement activities undertaken. Failure to pay charges invoiced under this chapter within thirty (30) days of billing shall constitute a violation of this chapter.
(Ord. 1661 - Jul. 10 Supp.)
1. Emergency Suspension. The enforcement officer may, without prior notice, suspend storm sewer system access to a property when such emergency suspension is necessary to stop an ongoing or imminent illicit discharge. If the responsible party fails to immediately comply with an emergency suspension order, the enforcement officer shall take such steps as deemed necessary to prevent, minimize, or remediate the illicit discharge. All costs of such action shall be recovered from the responsible party for the property identified as the source of the illicit discharge.
(Ord. 1661 - Jul. 10 Supp.)
2. Non-Emergency Suspension. If the enforcement officer detects or is informed of circumstances which could cause an illicit discharge but such illicit discharge is not ongoing or imminent, and if the suspension of storm sewer system access would reasonably be expected to prevent or reduce the potential illicit discharge, the enforcement officer shall notify the responsible party of the proposed suspension of storm sewer system access and the time and date of such suspension. Notice to one responsible party for the property shall be sufficient notice to all. Remediation of the circumstances shall avoid a violation of this chapter, provided that no illicit discharge occurs. In the alternative, the responsible party may request a meeting with the enforcement officer for the purpose of presenting information which the responsible party believes will show that remediation is unnecessary, and if the enforcement officer finds such information is satisfactory, the enforcement officer may rescind or modify the notice of suspension. If the enforcement officer finds such information unsatisfactory, the enforcement officer shall issue a final written order of suspension including the date and time of suspension and such order may be appealed as provided herein. Any physical action to reinstate storm sewer system access to property subject to such order prior to obtaining a court order of relief shall be deemed a violation of this chapter. An order of suspension shall not preclude charging the responsible party with a municipal infraction as provided herein or taking any other enforcement action permitted by statute or ordinance.
Every person owning property through which a watercourse passes, or such person's lessee, shall keep and maintain that part of the watercourse within the property free of trash, debris, grass clippings or other organic wastes and other obstacles that would pollute, contaminate, or significantly alter the quality of water flowing through the watercourse. 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.
(Ord. 1661 - Jul. 10 Supp.)
Violation of any provision of this chapter may be enforced by civil action including an action for injunctive relief. In any civil enforcement action, administrative or judicial, the City shall be entitled to recover its attorneys’ fees and costs from a person who is determined by a court of competent jurisdiction to have violated this chapter. Violation of any provision of this chapter may also be enforced as a municipal infraction within the meaning of Section 364.22 of the Code of Iowa, pursuant to Chapter 4 of this Code of Ordinances. Enforcement pursuant to this section shall be undertaken by the enforcement officer upon the advice and consent of the City Attorney.
