[HISTORY: Adopted by the Town Meeting of the Town of Avon 6-29-2020 ATM by Art. 9. Amendments noted where applicable.]
A. 
The United States Environmental Protection Agency has identified land disturbance and polluted stormwater runoff as major sources of water pollution. Regulation of illicit connections and discharges to the municipal storm drain system is necessary for the protection of the Town of Avon's water bodies and groundwater resources and to safeguard the public health, safety, and welfare and the natural resources of the Town. Increased volumes of stormwater and contaminated stormwater runoff are major causes of:
(1) 
Impairment of water quality and reduced flow in lakes, ponds, streams, rivers, wetlands, and groundwater;
(2) 
Contamination of drinking water supplies;
(3) 
Alteration or destruction of aquatic and wildlife habitat; and
(4) 
Flooding.
B. 
The purpose of this bylaw is to prohibit and eliminate illicit connections and discharges; safeguard the public health, safety, environment, and general welfare; protect aquatic resources and wildlife habitat; protect the quality and health of water resources; conserve groundwater supplies; and foster climate change resiliency.
C. 
This bylaw seeks to meet that purpose through the following objectives:
(1) 
To prevent pollutants from entering the Town of Avon's municipal storm drain system;
(2) 
To prohibit illicit connections and unauthorized discharges to the municipal storm drain system;
(3) 
To require the removal of all such illicit connections;
(4) 
To comply with state and federal statutes and regulations relating to stormwater discharges; and
(5) 
To establish the legal authority to ensure compliance with the provisions of this bylaw through inspection, monitoring, and enforcement.

In the event any person fails to comply with an emergency suspension order, the Select Board may take all reasonable steps to prevent or minimize harm to the public health, safety, welfare or the environment.
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 of Massachusetts, 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 Avon Fire and Police Departments.
