A. 
Authority. This article is adopted under the authority granted by ss. 283.33, Wis. Stats., and required by § NR 216.07(3)(a), Wis. Adm. Code.
B. 
Legislative findings. The Village Board of the Village of Cottage Grove finds that discharges to the municipal separate storm sewer system that are not composed entirely of stormwater runoff contribute to increased nonpoint source pollution and degradation of receiving waters. The impacts of these discharges adversely affect public health and safety, drinking water supplies, recreation, fish and other aquatic life, property values and other uses of lands and waters.
C. 
Purpose and intent. This article establishes methods for controlling the introduction of pollutants into the municipal separate storm sewer system (MS4) in order to comply with requirements of the Wisconsin Pollutant Discharge Elimination System (WPDES) permit process. The objectives of this article are:
(1) 
To regulate the contribution of nonstormwater pollutants to the municipal separate storm sewer system (MS4) by stormwater discharges by any user;
(2) 
To prohibit illicit connections and discharges to the municipal separate storm sewer system;
(3) 
To establish legal authority to carry out all inspection, surveillance and monitoring procedures necessary to ensure compliance with this article.
D. 
Abrogation and greater restrictions. It is not intended by this article to repeal, abrogate, annul, impair or interfere with any existing easements, covenants, deed restrictions, agreements, rules, regulations, ordinances or permits previously adopted or issued pursuant to law. However, wherever this article imposes greater restrictions, the provisions of this article shall govern.
E. 
Interpretation. In their interpretation and application, the provisions of this article shall be held to be the minimum requirements and shall not be deemed a limitation or repeal of any other power granted by the Wisconsin Statutes. Where any terms or requirements of this article may be inconsistent or conflicting, the more restrictive requirement or interpretation shall control.

B. 
Prohibition of illegal connections.
(1) 
The construction, use, maintenance or continued existence of illicit connections to the storm drain system is prohibited. This prohibition expressly includes, without limitation, illicit connections made in the past, regardless of whether the connection was permissible under law or practices application or prevailing at the time of connection.
(2) 
A person is in violation of this article if the person connects a line conveying sewage to the MS4 or allows such a connection to continue.
(3) 
Any drain or conveyance that has not been documented in plans, maps or equivalent, and which may be connected to the storm sewer system, shall be located by the owner or occupant of that property upon receipt of written notice of violation from the Director of Public Works requiring that such locating be completed. Such notice will specify a reasonable time period within which the location of the drain or conveyance is to be completed, that the drain or conveyance be identified as storm sewer, sanitary sewer or other, and the outfall location or point of connection to the storm sewer system, sanitary sewer system or other discharge point be identified. Results of these investigations are to be documented and provided to the Director of Public Works.
A. 
Suspension due to illicit discharges in emergency situations.
(1) 
The Director of Public Works may, without prior notice, suspend MS4 discharge access to a person when such suspension is necessary to stop an actual or threatened discharge that presents or may present imminent and substantial danger to the environment, to the health or welfare of persons, or to the MS4 or waters of the state.
(2) 
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 state or to minimize danger to persons.
B. 
Suspension due to the detection of illicit discharge.
(1) 
Any person discharging to the MS4 in violation of this article may have its MS4 access terminated if such termination would abate or reduce an illicit 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.
(2) 
A person commits an offense if the person reinstates MS4 access to premises terminated pursuant to this section without the prior approval of the authorized enforcement agency.

Any person responsible for a property or premises which is or may be, the source of an illicit discharge may be required to implement, at said person's expense, structural and nonstructural BMPs, in additional to those required by Subsection B, to prevent the further discharge of pollutants to the municipal separate storm sewer system.
D. 
Compliance with all terms and conditions of a valid WPDES permit authorizing the discharge of stormwater 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 (SWPP) as necessary for compliance with requirements of the National Pollutant Discharge Elimination System (NPDES) permit.
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, excessive vegetation, and other obstacles that would pollute, contaminate, cause erosion, or significantly retard the flow of water 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.

All devices used to measure flow and quality shall be calibrated to ensure their accuracy.
E. 
Any temporary or permanent obstruction to safe and easy access to the property or facility to be inspected and/or sampled shall be promptly removed by the owner or operator at the written or oral request of the Director of Public Works or his/her designee and shall not be replaced. The costs of clearing such access shall be borne by the owner or operator.
F. 
Unreasonable delays in allowing the Director of Public Works or his/her designee access to a facility is a violation of this article.
G. 
If the Director of Public Works or his/her designee has been refused access to any part of the premises from which stormwater is discharged, and the Director of Public Works or his/her designee is able to demonstrate probable cause to believe that there may be a violation of this article 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 article or any order issued hereunder, or to protect the overall public health, safety, environment and welfare of the community, then the Director of Public Works or his/her designee may seek issuance of a search warrant from any court of competent jurisdiction.
A. 
Notwithstanding other requirements of law, as soon as any person responsible for a facility, activity or operation, or responsible for emergency response for a facility, activity or operation, has information of any known or suspected release of pollutants or nonstormwater discharges from that facility or operation, which are resulting or may result in illicit discharges or pollutants discharging into stormwater, the Village's municipal separate storm sewer system, waters of the state, or waters of the United States, said person shall take all necessary steps to ensure the discovery, containment, and cleanup of such release so as to minimize the effects of the discharge.
B. 
Said person shall notify the authorized enforcement agency in person or by phone, facsimile or in person no later than 24 hours of the nature, quantity and time of occurrence of the discharge. Notifications in-person or by phone shall be confirmed by written notice addressed and mailed to the Director of Public Works within three business days of the phone or in-person notice. If the discharge of prohibited materials 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. Said person shall also take immediate steps to ensure no recurrence of the discharge or spill.
C. 
In the event of such a release of hazardous materials, emergency response agencies and/or other appropriate agencies shall be immediately notified.
