[Adopted as Art. 37 of the Town Bylaws]
This bylaw is adopted in accordance with the authority granted, inter alia, by Amendment Article 89 to Article
II of the Massachusetts Constitution and MGL c. 43B, § 13. The Select Board is delegated hereby the responsibility and authority to enforce and administer this bylaw. The Select Board may appoint the Town Engineer or Assistant Town Engineer or such other Town employee as the Select Board may from time to time determine and designate in a writing to aid the Select Board in the enforcement and/or administration of this bylaw.
In partial fulfillment of the obligations of the Town under
the Clean Water Act (33 U.S.C. § 1251 et seq.) (the "Act")
and under the Town's National Pollutant Discharge Elimination System
Stormwater Permit, the Town hereby establishes a comprehensive and
fair system of regulation of discharges to the Town's municipal separate
storm sewer system (sometimes referred to herein as the "MS4").
The purpose and intent of this bylaw is to:
A. Protect the waters of the U.S., as defined in the Act and its implementing
regulations, from uncontrolled discharges of stormwater or discharges
of contaminated water which have a negative impact on the receiving
waters by changing the physical, biological and chemical composition
of those waters, resulting in an unhealthy environment for aquatic
organisms, wildlife and people; and
B. Reduce discharges of contaminated water into the MS4 and resultant
discharges from the MS4 into waters of the U.S. and improve surface
water quality; and
C. Permit and manage reasonable access to the MS4 to facilitate proper
drainage; and
D. Assure that the Town can continue to fairly and responsibly protect
the public health, safety and welfare.
As used in this bylaw, the following terms shall have the meanings
indicated:

POST-DEVELOPMENT
The conditions that reasonably may be expected or anticipated
to exist after completion of the land development activity on a specific
site or tract of land. Post-development refers to the phase of a new
development or redevelopment project after completion, and does not
refer to the construction phase of a project.
PRE-DEVELOPMENT
The conditions that exist at the time that plans for the
land development of a tract of land are submitted to the Stormwater
Authority. Where phased development or plan approval occurs (preliminary
