A. 
The purpose of this bylaw is to protect the health, safety, general welfare, and environment by regulating illicit connections and discharges to the storm drain system or, directly or indirectly, to a watercourse or into the waters of the commonwealth, as well as to control 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 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.
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 system (MS4) and reduce or eliminate pollutants entering the Towns 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 establish the Town of Rockland's legal authority to ensure compliance with the provisions of this bylaw through inspection, monitoring, and enforcement.
