The Board 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 Board and/or any other authorized
Town Official and/or any other authorized employee or agent of the
Town may take all reasonable steps to prevent or minimize harm to
the public health, safety, welfare or the environment.

law, as soon as a person responsible 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 Town of Dennis Fire and Police
Departments and the Board of Health. In the event of a release of
non-hazardous material, the reporting person shall notify the Authorized
Enforcement Agency no later than the next business day. The reporting
person shall provide to the Board 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.
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
