A. 
The purpose of this bylaw is to protect natural resources, municipal facilities and maintain and enhance public health, safety, welfare, and environment by regulating illicit connections and discharges to the Town of Hull's MS4 system and controlling the adverse effects of construction site stormwater runoff and post-construction runoff. Stormwater runoff is potentially a major cause of:
(1) 
Impairment of water quality and flow in oceans, lakes, ponds, streams, rivers, wetlands, groundwater and drinking water supplies;
(2) 
Contamination of drinking water supplies;
(3) 
Contamination of downstream coastal areas;
(4) 
Alteration or destruction of aquatic and wildlife habitat;
(5) 
Overloading or clogging of municipal stormwater management systems; and
(6) 
Flooding.
(7) 
And other adverse effects on the environment, public health, safety and welfare and the orderly and effective operation of the Town.
B. 
The objectives of this bylaw are:
(1) 
Protect water resources;
(2) 
Comply with state and federal statutes and regulations relating to stormwater discharges including total maximum daily load requirements;
(3) 
To prevent pollutants from entering the Town's municipal separate storm sewer system (MS4) and reduce or eliminate pollutants entering the Town's MS4 from existing uses;
(4) 
To prohibit illicit connections and unauthorized discharges to the MS4 and require their removal;
(5) 
To establish minimum construction and post construction stormwater management standards and design criteria for the regulation and control of stormwater runoff quantity and quality;
(6) 
To establish provisions for the long-term responsibility for, and maintenance of, structural stormwater control facilities and nonstructural stormwater management practices to ensure that they continue to function as designed, are maintained, and pose no threat to public safety; and
(7) 
To ensure the legal authority to ensure compliance with the provisions of this bylaw through inspection, monitoring, and enforcement.
C. 
In the event of a conflict between this Bylaw and/or the regulations promulgated and any other applicable law, rule or regulation, the more stringent shall apply unless a variance or exception is granted by the Stormwater Authority upon application to it.
D. 
Nothing contained herein or in any regulations promulgated or in any permit or authorization issued shall be construed to be a specific assurance of safety or assistance.
