The Department of Public Works may suspend municipal storm drain system access to any person or property without prior written notice when such suspension is necessary to stop an actual or threatened discharge of pollutants that presents imminent risk of harm to the public health, safety, welfare or the environment. In the event any person fails to comply with an emergency suspension order, the authorized enforcement agency may take all reasonable steps to prevent or minimize harm to the public health, safety, welfare or the environment.
A. 
The Department of Public Works will adopt requirements identifying best management practices for any activity, operation, or facility which may cause or contribute to pollution or contamination of stormwater, the storm drain system, or waters of the United States. 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 nonstructural BMPs.
B. 
Further, 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, additional structural and nonstructural BMPs to prevent the further discharge of pollutants to the municipal separate storm sewer system.
C. 
Compliance with all terms and conditions of a valid NPDES 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 NPDES permit.
Notwithstanding other requirements of local, state or federal law, as soon as a person responsible for a facility or operation, or responsible for emergency response for a facility or operation has information of or suspects a release of materials at that facility or operation resulting in or which may result in discharge of pollutants to the municipal drainage system or waters of the commonwealth, the person shall take all necessary steps to ensure containment and cleanup of the release. In the event of a release of oil or hazardous materials, the person shall immediately notify the municipal Fire and Police Departments and Natural Resources and Public Works Departments. In the event of a release of nonhazardous material, the reporting person shall notify the authorized enforcement agency no later than the next business day. The reporting person shall provide to the authorized enforcement agency written confirmation of all telephone, facsimile or in-person notifications within three business days thereafter. If the discharge of prohibited materials is from a commercial or industrial facility, the facility owner or operator of the facility shall retain on-site a written record of the discharge and the actions taken to prevent its recurrence. Such records shall be retained for at least three years.
A. 
The Department of Public Works, or any authorized agent of the Department of Public Works, shall enforce this bylaw, regulations, orders, violation notices, and enforcement orders, and may pursue all civil and criminal remedies for such violations.
B. 
Civil relief. If a person violates the provisions of this bylaw, regulations, permit, notice, or order issued thereunder, the Department of Public Works may seek injunctive relief in a court of competent jurisdiction restraining the person from activities which would create further violations or compelling the person to perform abatement or remediation of the violation.
C. 
Orders. The Department of Public Works, or an authorized agent of the Department of Public Works, may issue a written order to enforce the provisions of this bylaw or the regulations thereunder, which may include:
(1) 
Elimination of illicit connections or discharges to the MS4;
(2) 
Performance of monitoring, analyses, and reporting;
(3) 
That unlawful discharges, practices, or operations shall cease and desist; and
(4) 
Remediation of contamination in connection therewith.
D. 
If the enforcing person determines that abatement or remediation of contamination is required, the order shall set forth a deadline by which such abatement or remediation must be completed. Said order shall further advise that, should the violator or property owner fail to abate or perform remediation within the specified deadline, Chatham may, at its option, undertake such work, and expenses thereof shall be charged to the violator.
E. 
Within 30 days after completing all measures necessary to abate the violation or to perform remediation, the violator and the property owner will be notified of the costs incurred by the Chatham, including administrative costs. The violator or property owner may file a written protest objecting to the amount or basis of costs with the Department of Public Works within 30 days of receipt of the notification of the costs incurred. If the amount due is not received by the expiration of the time in which to file a protest or within 30 days following a decision of the Department of Public Works affirming or reducing the costs, or from a final decision of a court of competent jurisdiction, the costs shall become a special assessment against the property owner and shall constitute a lien on the owner's property for the amount of said costs. Interest shall begin to accrue on any unpaid costs at the statutory rate provided in MGL c. 59, § 57, after the 31st day at which the costs first become due.
F. 
Violations of this bylaw shall be subject to noncriminal dispositions pursuant of the provisions of Chapter 1, § 1-7, of these bylaws.
G. 
Notwithstanding the general penalties set forth under Chapter 1, § 1-7, of these Bylaws, the specific penalties for violations of this bylaw shall be as follows:
(1) 
First offense: a fine of $50.
(2) 
Second offense: a fine of $100.
(3) 
Third and subsequent offense: a fine of $150.
H. 
Entry to perform duties under this bylaw. To the extent permitted by state law, or if authorized by the owner or other party in control of the property, the Department of Public Works, its agents, officers, and employees may enter upon privately owned property for the purpose of performing their duties under this bylaw and regulations and may make or cause to be made such examinations, surveys or sampling as the Department of Public Works deems reasonably necessary.
I. 
Appeals. The decisions or orders of the Department of Public Works shall be final. Further relief shall be to a court of competent jurisdiction.
J. 
Remedies not exclusive The remedies listed in this bylaw are not exclusive of any other remedies available under any applicable federal, state or local law.
The provisions of this bylaw are hereby declared to be severable. If any provision, paragraph, sentence, or clause of this bylaw 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 bylaw.
