[Adopted 12-22-2008]
In order to protect the General Public from the hazards inherent in open, unattended trenches the Commonwealth of Massachusetts has enacted legislation in the form of Chapter 82A of the General Laws requiring a permitting process be established for opening trenches on public and private property. This regulation is the local implementing directive for the permitting process for excavation of trenches on PRIVATE PROPERTY and on PUBLIC PROPERTY NOT WITHIN THE LAYOUT OF a PUBLIC WAY. Rules and Regulations governing work performed within the layout of public roadways are found in Chapter 197 of the Code of the Town of Northbridge, Article I, Road Opening Permit Rules and Regulations.

(2) 
520 CMR 14.00, Excavation and Trench Safety (a copy of which is attached herewith). Compliance with the requirements of this state regulation is implicit in the issuance of a permit under this regulation.[1]

A. 
Immediate Shutdown: Whenever the permitting authority, or an inspector from either the Department of Public Safety or the Division of Occupational Safety deems a condition at a trench site to be a threat to public safety he may order that the area around the trench be made safe for the general public and may further order the immediate shutdown of the site until such time as the condition has been corrected to the satisfaction of the authority responsible for the immediate shutdown.
