No decision to carry out or approve an action which may have a significant effect upon the environment shall be made until after the filing and consideration of a final environmental impact statement. The Planning Board's decision whether or not to approve an action which has been the subject of an environmental impact statement shall be made within 30 calendar days of the filing of a final environmental impact statement.
When the Planning Board decides to carry out or approve an action which may have a significant effect upon the environment, it shall make the following findings in a written statement.
A. 
Consistent with social, economic and other essential considerations of state policy, from among the reasonable alternatives thereto, the action to be carried out or approved is one which minimizes or avoids adverse environmental effects to the maximum extent possible, including the effects disclosed in the relevant environmental impact statement.
B. 
Consistent with social, economic and other essential considerations of state policy, all practicable means will be taken in carrying out or approving the action to minimize or avoid adverse environmental effects.
For public information purposes, a copy of the determination shall be filed immediately in the same manner as the draft environmental impact statement. The Town Clerk shall maintain a file, open to public inspection, of all notices of determination prepared by it.
