The Director shall administer, implement, and enforce the provisions of this article. Any powers granted or duties imposed upon the Director may be delegated, in writing, by the Director to persons or entities acting in the beneficial interest of or in the employ of the Town of Thompson.
This article is not intended to modify or repeal any other ordinance, rule, regulation, or other provision of law. The requirements of this article are in addition to the requirements of any other ordinance, rule, regulation, or other provision of law, and where any provision of this article 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.

If any provision, clause, sentence, or paragraph of this article or the application thereof to any person, establishment, or circumstances shall be held invalid, such invalidity shall not affect the other provisions or application of this article.
The standards set forth herein and promulgated pursuant to this article are minimum standards; therefore, this article does not intend nor imply that compliance by any person will ensure that there will be no contamination, pollution, nor unauthorized discharge of pollutants.
A. 
Prohibition of illicit discharges and exemptions.
(1) 
No person shall throw, drain or otherwise discharge, cause or allow others under its control to throw, drain, or otherwise discharge into the Thompson's MS4 any pollutants or waters containing any pollutants that cause or contribute to a violation of Connecticut Water Quality Standards, as amended.
(2) 
The commencement, conduct or continuance of any illicit discharge to Thompson's MS4 is prohibited except as described as follows:
(a) 
The following discharges are exempt from discharge prohibitions established by this article: uncontaminated groundwater discharges, including, but not limited to, pumped groundwater, foundation drains, water from crawl space pumps and footing drains; irrigation water, including, but not limited to, landscape irrigation and lawn watering runoff; residual street wash water associated with sweeping; discharges or flows from firefighting activities (except training); and naturally occurring discharges such as rising groundwaters, uncontaminated groundwater infiltration [as defined at 40 CFR 35.2005(20)], springs, diverted stream flows and flows from riparian habitats and wetlands.
(b) 
Any nonstormwater discharge to Thompson's MS4 authorized by a permit issued pursuant to § 22a-430 or § 22a-430b of the Connecticut General Statutes is also authorized under this article.
B. 
Prohibition of illicit connections.
(1) 
The construction, use, maintenance or continued existence of illicit connections to Thompson's 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 article if the person makes a connection conveying sewage to Thompson's MS4, or allows such a connection to continue.
[Amended 5-30-2023]
Upon the receipt of a complaint or evidence that an illicit discharge and/or connection exists, the Director shall conduct or cause an investigation to determine the existence and/or origin of the illicit discharge and/or illicit connection. The Director will make or cause preliminary contact with the property owner or facility operator and seek abatement of the illicit discharge and/or illicit connection. If the source appears to originate from property containing an industrial or construction site, the Director may or may cause additionally contact the DEEP to determine if the property is subject to permitting by the DEEP and assess if the illicit discharge and/or connection is in violation of the DEEP permit. If within 15 days of the preliminary contact the property owner or facility operator of such permitted property does not willingly abate the illicit discharge/connection, the Director shall either issue an order to abate pursuant to the provision of this article and/or notify the DEEP of the suspected permit violation for enforcement action by the DEEP.
Any person subject to an industrial or construction activity NPDES stormwater 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 Director prior to the allowing of discharges to Thompson's MS4.
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, Thompson's MS4, or water of the state, said person shall take all necessary steps to ensure the discovery, containment, and cleanup of such release. In the event of such a release of hazardous materials, said person shall immediately notify DEEP Emergency Response Unit and Thompson's 911 emergency dispatch services. In the event of a release of nonhazardous materials, said person shall notify the Director 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 Director of Public Works, Thompson Town Hall, North Grosvenordale CT 06255 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 three years.
A. 
Suspension due to illicit discharges in emergency situations. In the event the Director finds an actual or threatened discharge presents or may present imminent and substantial danger to the environment, or to the health or welfare of persons, or to Thompson's MS4 or waters of the state, the Director will immediately notify the DEEP of such danger and may, without additional notice, take actions to cause the immediate suspension of the MS4 discharge access to Thompson's MS4. Such actions may include, but are not limited to, the physical blockage to Thompson's MS4 and issuing an order to immediately abate the illicit discharge pursuant to § 236-13 of this article.
B. 
Suspension due to the detection of illicit discharge. Any person discharging to Thompson's MS4 in violation of this article may have their MS4 access terminated in accordance with §§ 236-13, 236-14 and 236-17 of this article if such termination would abate or reduce an illicit discharge.
A. 
Whenever the Director finds that a person has created or is maintaining an illicit discharge and/or illicit connection to the Thompson MS4 in violation of § 236-8 of this article, the Director may issue by certified mail a written order to abate such discharge and/or connection and cause the termination of such discharge and/or connection. The order may require without limitation:
(1) 
The elimination of illicit connections and/or discharges;
(2) 
That violating discharges, practices, or operations shall cease and desist;
(3) 
The abatement or remediation of stormwater pollution or contamination hazards and the restoration of any affected property;
(4) 
Payment to recoup costs incurred by the Director;
(5) 
Suspension of any discharge to Thompson's MS4 system consistent with § 236-12 of this article; and
(6) 
The implementation of source control or treatment BMPs.
B. 
If abatement of the violation and/or remediation of affected property is required, the order shall set forth a deadline within which such abatement and/or remediation must be completed. Where elimination is not possible within 60 days of source confirmation, a schedule for its elimination will be set for no more than 120 days.
C. 
Said order shall further instruct that, should the actions required by the order fail to be completed within the established deadline, such actions may be performed at the Director's direction. The person to whom the order is issued is liable for any expenses incurred by the Director in abetting the violation.
[Amended 5-30-2023]
Any person receiving an order to abate may, in writing, appeal the order to the Select Board for reconsideration. The notice of appeal must be received within 14 days of the date of the order to abate. A hearing on the appeal before the Select Board designee shall take place within 21 days of the date of receipt of the notice of appeal. The decision of the Select Board shall be final.
If the illicit discharge or illicit connection has not been abated pursuant to the requirements set forth in the order to abate or, in the event of an appeal, within 14 days of the decision of the Select Board upholding the decision of the Director, then the Director shall, in the case of industrial discharges, refer the matter to the DEEP for its enforcement under § 22a-432 of the Connecticut General Statutes; or, in the case of construction activities causing pollution to waters of the state by the failure to control erosion and sedimentation, refer the matter to either the DEEP, the Thompson Inland Wetlands Commission or the Thompson Planning and Zoning Commission, as the Director deems appropriate.
Within 45 days after abatement of the violation, the owner of the property will be notified, in writing by certified mail, of the cost of abatement, including administrative costs, and the payment requirements. The property owner may file a written protest objecting to the amount of the assessed costs within 14 days of written notification. If the amount due is not paid within a timely manner as determined by the decision of the Select Board or by the expiration of the time in which to file an appeal, the cost of the abatement charges shall become a special tax assessment against the property and subject to collection pursuant to the provisions of §§ 12-172 and 12-173 of the Connecticut General Statutes. Payment and interest on abatement charges shall be in accordance with § 12-144 of the Connecticut General Statutes unless otherwise determined by the Select Board.
It shall be unlawful for any person to violate any provision or fail to comply with any of the requirements of this article. If a person has violated or continues to violate the provisions of this article or order to abate, the Director or Select Board may petition for a permanent injunction restraining the person from activities which would create further violations or compelling the person to perform abatement or remediation of the violation.
In addition to the enforcement processes and penalties allowed by law, any condition caused or permitted to exist in violation of any of the provisions of this article is a threat to public health, safety, and welfare, and is declared and deemed a nuisance.
The remedies listed in this article are not exclusive of any other remedies available under any applicable federal, state or local law, and it is within the discretion of the Director to seek cumulative remedies.
This article shall be in full force and effect 15 days after its publication in a newspaper of general circulation in Thompson. All prior ordinances and parts of ordinances in conflict with this article are hereby repealed.
