WISCONSIN POLLUTANT DISCHARGE ELIMINATION SYSTEM (WPDES) STORMWATER DISCHARGE PERMIT
A Wisconsin pollutant discharge elimination system permit issued pursuant to Ch. 283, Wis. Stats.
This chapter shall apply to all water and discharges entering waters of the state or the MS4 generated on any lands, unless explicitly exempted by the Village Administrator.
The Village Administrator shall administer, implement, and enforce the provisions of this chapter. Any powers granted or duties imposed upon the Village Administrator may be delegated in writing by the Village Administrator to persons or entities acting in the beneficial interest of or in the employ of the authorized enforcement agency.
This chapter is not intended to modify or repeal any other ordinance, rule, regulation, or other provision of law. The requirements of this chapter are in addition to the requirements of any other ordinance, rule, regulation, or other provision of law, and where any provision of this chapter imposes restrictions different from those imposed by any other ordinance, rule, regulation, or other provision of law, whichever provision is more restrictive or imposes higher protective standards for human health or the environment shall control.
The standards set forth herein and promulgated pursuant to this chapter are minimum standards; therefore, this chapter does not intend or imply that compliance by any person will ensure that there will be no contamination, pollution, or unauthorized discharge of pollutants.
A. 
Prohibition of illicit discharges. No person shall throw, dump, spill, drain, or otherwise discharge, cause, or allow others under its control to throw, dump, spill, drain, or otherwise discharge into waters of the state or the MS4 any pollutants or waters containing any pollutants, other than stormwater.
B. 
Allowed discharges.
(1) 
The following discharges are allowed:
(a) 
Waterline flushing, landscape irrigation, diverted stream flows, uncontaminated groundwater infiltration, uncontaminated pumped groundwater, discharges from potable water sources, foundation drains, air-conditioning condensation, irrigation water, lawn watering, individual residential car washing, flows from riparian habitats and wetlands, and discharges authorized under a WPDES permit, unless identified by the Village Administrator as a significant source of pollutants to waters of the state.
(b) 
Discharges or flow from firefighting and other discharges specified in writing by the Village Administrator as being necessary to protect public health and safety.
(c) 
Discharges associated with dye testing; however, this activity requires a verbal notification to the Village Administrator and the Department of Natural Resources a minimum of one business day prior to the time of the test.
(2) 
Any nonstormwater discharges permitted under a construction activity permit, industrial activity permit, or WPDES permit shall comply with all provisions of such permit. Proof of compliance with said permit may be required in a form acceptable to the Village Administrator prior to allowing discharges to waters of the state or the MS4.
C. 
Prohibition of illicit connections.
(1) 
The construction, use, maintenance or continued existence of illicit connections to waters of the state or the MS4 is prohibited.
(2) 
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.
(3) 
A person is considered to be in violation of this chapter if the person connects a line conveying sewage to waters of the state or the MS4, or allows such a connection to continue.
(4) 
Improper connections in violation of this chapter must be disconnected and redirected, if necessary, to an approved on-site wastewater management system or the sanitary sewer system upon approval of the Village Administrator.
(5) 
Any drain or conveyance that has not been documented in plans, maps or equivalent, and which may be connected to waters of the state or the MS4, shall be located by the owner or occupant of that property upon receipt of written notice of violation from the Village Administrator 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 determined, that the drain or conveyance be identified as storm sewer, sanitary sewer or other, and that 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 Village Administrator.
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 soil erosion, trash, debris, and other obstacles that would pollute, contaminate, 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.
A. 
Right of entry; inspecting and sampling. The Village Administrator shall be permitted to enter and inspect properties and facilities subject to regulation under this chapter as often as may be necessary to determine compliance with this chapter.
(1) 
If a property or facility has security measures in force which require proper identification and clearance before entry into its premises, the owner or operator shall make the necessary arrangements to allow access to representatives of the Village Administrator.
(2) 
Facility owners and operators shall allow the Village Administrator ready access to all parts of the premises for the purposes of inspection, sampling, examination and copying of records.
(3) 
The Village Administrator may set up on any property or facility such devices as are necessary in the opinion of the Village Administrator to conduct monitoring and/or sampling of the facility's stormwater discharge.
(4) 
The Village Administrator may require the owner or operator to install monitoring equipment as necessary and make the monitoring data available to the Village Administrator. 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 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 Village Administrator and shall not be replaced. The costs of clearing such access shall be borne by the owner or operator.
(6) 
Unreasonable delays in allowing the Village Administrator access to a facility are a violation of this chapter. A person who is the operator of a facility commits an offense if the person denies the Village Administrator reasonable access to the facility for the purpose of conducting any activity authorized or required by this chapter.
B. 
Special inspection warrant. If the Village Administrator has been refused access to any part of the premises from which stormwater is discharged, and the Village Administrator has 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, environment and welfare of the community, then the Village Administrator may seek issuance of a special inspection warrant per § 66.0119, Wis. Stats., and this chapter.
The owner or operator of any activity, operation, or facility which may cause or contribute to pollution or contamination of stormwater shall provide, at its own expense, reasonable protection from accidental discharge of prohibited materials or other wastes into waters of the state or the MS4 through the use of structural and nonstructural BMPs. Further, any person responsible for a property or premises that is, or may be, the source of an illicit discharge may be required to implement, at said person's expense, additional structural and nonstructural BMPs to prevent the further discharge of pollutants to waters of the state or the MS4. Compliance with all terms and conditions of a valid permit authorizing the discharge of stormwater associated with industrial activity or construction activity, to the maximum extent practicable, shall be deemed compliance with the provisions of this section.
A. 
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, has information of any known or suspected release of materials which are resulting or may result in illicit discharges or pollutants discharging into stormwater, the MS4, or waters of the state, said person shall take all necessary steps to ensure the discovery, containment, and cleanup of such release, so as to minimize the impacts of the discharge.
B. 
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 and shall also notify the Village Administrator. In the event of a release of nonhazardous materials, said person shall notify the Village Administrator in person or by phone or facsimile no later than the next business day. Notifications in person or by phone shall be confirmed by written notice addressed and mailed to the Village Administrator within three business days of the phone 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 five years.
C. 
Failure to provide notification of a release as provided above is a violation of this chapter.
A. 
Violations.
(1) 
It shall be unlawful for any person to violate any provision or fail to comply with any of the requirements of this chapter. Any person who has violated or continues to violate the provisions of this chapter may be subject to the enforcement actions outlined in this section, or the violation may be restrained by injunction or otherwise abated in a manner provided by law.[1]
[1]
Editor's Note: Amended at time of adoption of Code (see Ch. 25, Construction and Effect of Ordinances, Art. II).
(2) 
In the event the violation constitutes an immediate danger to public health or public safety, the Village Administrator is authorized to enter upon the subject private property, without giving prior notice, to take any and all measures necessary to abate the violation. The Village Administrator is authorized to seek costs of the abatement as outlined in § 17-17.
B. 
Warning notice. When the Village Administrator finds that any person has violated, or continues to violate, any provision of this chapter, or any order issued hereunder, the Village Administrator may serve upon that person a verbal or written warning notice specifying the particular violation believed to have occurred and requesting the discharger to immediately investigate the matter and to seek a resolution whereby any offending discharge will cease. Investigation and/or resolution of the matter in response to the warning notice in no way relieves the alleged violator of liability for any violations occurring before or after receipt of the warning notice. Nothing in this subsection shall limit the authority of the Village Administrator to take action, including emergency action or any other enforcement action, without first issuing a warning notice.
C. 
Notice of violation.
(1) 
Whenever the Village Administrator finds that a person has violated a prohibition or failed to meet a requirement of this chapter, the Village Administrator may order compliance by written notice of violation to the responsible person.
(2) 
The notice of violation shall contain:
(a) 
The name and address of the alleged violator;
(b) 
The address when available or a description of the building, structure or land upon which the violation is occurring, or has occurred;
(c) 
A statement specifying the nature of the violation;
(d) 
A description of the remedial measures necessary to restore compliance with this chapter and a time schedule for the completion of such remedial action;
(e) 
A statement of the penalty or penalties that shall or may be assessed against the person to whom the notice of violation is directed;
(f) 
A statement that the determination of violation may be appealed to the Village Administrator by filing a written notice of appeal within three business days of service of notice of violation; and
(g) 
A statement specifying that, should the violator fail to restore compliance within the established time schedule, representatives of the Village Administrator may issue a notice of intent to the responsible party of their intent to perform work necessary to comply with this chapter. The Village Administrator may go on the land and commence the work after issuing the notice of intent. The Village Administrator is authorized to seek costs of the abatement as outlined in § 17-17.
(3) 
Such notice may require without limitation:
(a) 
The performance of monitoring, analyses, and reporting;
(b) 
The elimination of illicit connections or discharges;
(c) 
That violating discharges, practices, or operations shall cease and desist;
(d) 
The abatement or remediation of stormwater pollution or contamination hazards and the restoration of any affected property;
(e) 
Payment of a fine to cover administrative and remediation costs; and
(f) 
The implementation of BMPs.
A. 
Emergency cease and desist orders.
(1) 
When the Village Administrator finds that any person has violated, or continues to violate, any provision of this chapter, or any order issued hereunder, or that the person's past violations are likely to recur, and that the person's violation(s) has (have) caused or contributed to an actual or threatened discharge to the MS4 or waters of the state which reasonably appears to present an imminent or substantial endangerment to the health or welfare of persons or to the environment, the Village Administrator may issue an order to the violator directing it immediately to cease and desist all such violations and directing the violator to:
(a) 
Immediately comply with all ordinance requirements; and
(b) 
Take such appropriate preventive action as may be needed to properly address a continuing or threatened violation, including immediately halting operations and/or terminating the discharge.
(2) 
Any person notified of an emergency order directed to it under this subsection shall immediately comply and stop or eliminate its endangering discharge. In the event of a discharger's failure to immediately comply voluntarily with the emergency order, the Village Administrator may take such steps as deemed necessary to prevent or minimize harm to the MS4 or waters of the state, and/or endangerment to persons or to the environment, including immediate termination of a facility's water supply, sewer connection, or other municipal utility services. The Village Administrator may allow the person to recommence its discharge when it has demonstrated to the satisfaction of the Village Administrator that the period of endangerment has passed, unless further termination proceedings are initiated against the discharger under this chapter. A person that is responsible, in whole or in part, for any discharge presenting imminent endangerment shall submit a detailed written statement, describing the causes of the harmful discharge and the measures taken to prevent any future occurrence, to the Village Administrator within 30 days of receipt of the emergency order. Issuance of an emergency order shall not be a bar against, or a prerequisite for, taking any other action against the violator.[1]
[1]
Editor's Note: Amended at time of adoption of Code (see Ch. 25, Construction and Effect of Ordinances, Art. II).
B. 
Suspension due to illicit discharges in emergency situations. The Village Administrator 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 state. If the violator fails to comply with a suspension order issued in an emergency, the Village Administrator 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.
C. 
Suspension due to the detection of illicit discharge. Any person discharging to the MS4 in violation of this chapter may have its MS4 access terminated if such termination would abate or reduce an illicit discharge. The Village Administrator will notify a violator of the proposed termination of its MS4 access. A person commits an offense if the person reinstates MS4 access to premises terminated pursuant to this section, without the prior approval of the Village Administrator.
A. 
Any person violating any provision of this chapter shall be punishable as prescribed in Chapter 40, Fees and Penalties, of this Code. Each day a violation exists shall constitute a separate offense.[1]
[1]
Editor's Note: Amended at time of adoption of Code (see Ch. 25, Construction and Effect of Ordinances, Art. II).
B. 
Compliance with the provisions of this chapter may also be enforced by injunction in any court with jurisdiction. It shall not be necessary to prosecute for forfeiture or a cease and desist order before resorting to injunctional proceedings.
A. 
The Village Board:[1]
(1) 
Shall hear and decide appeals where it is alleged that there is error in any order, decision or determination made by the Village Administrator in administering this chapter, except for cease and desist orders obtained under § 17-13.
(2) 
Upon appeal, may authorize variances from the provisions of this chapter which are not contrary to the public interest and where, owing to special conditions, a literal enforcement of the provisions of this chapter will result in unnecessary hardship.
[1]
Editor's Note: Amended at time of adoption of Code (see Ch. 25, Construction and Effect of Ordinances, Art. II).
B. 
Who may appeal. Appeals to the Village Board may be taken by any aggrieved person or by any office, department, board, or bureau of the Village of Sherwood affected by any decision of the Village Administrator.
If the violation has not been corrected pursuant to the requirements set forth in the notice of violation, or, in the event of an appeal, the appropriate authority upheld the decision of the Village Administrator, then representatives of the Village Administrator may issue a notice of intent to the responsible party of their intent to perform work necessary to comply with this chapter. The Village Administrator may go on the land and commence the work after issuing the notice of intent. The Village Administrator is authorized to seek costs of abatement as outlined in § 17-17. It shall be unlawful for any person, owner, agent or person in possession of any premises to refuse to allow the government agency or designated contractor to enter upon the premises for the purposes set forth above.
The costs of the work performed by the Village Administrator pursuant to this chapter, plus interest at the rate authorized by the Village Administrator, shall be billed to the responsible party. In the event a responsible party fails to pay the amount due, the Clerk-Treasurer shall enter the amount due on the tax rolls and collect it as a special assessment against the property pursuant to Subchapter VII of Ch. 66, Wis. Stats.
Any condition in violation of any of the provisions of this chapter and declared and deemed a nuisance may be summarily abated or restored at the violator's expense.
A. 
The remedies listed in this chapter are not exclusive of any other remedies available under any applicable federal, state or local law, and it is within the discretion of the Village Administrator to seek cumulative remedies.
B. 
The Village Administrator may recover all attorneys' fees, court costs and other expenses associated with enforcement of this chapter, including sampling and monitoring expenses.
