relative to notification waiting periods to the underground utility damage prevention laws.

HB 1169 shortens the required notice period for excavators to contact utility damage prevention systems from 72 to 48 hours (excluding weekends and 6 specified holidays), and extends the validity of excavation notifications from 30 days to one year if site conditions remain unchanged. This directly affects construction companies, contractors, and anyone planning underground excavation work in New Hampshire. The key changes streamline notification timing for excavators while allowing longer validity for unchanged sites, reducing repeated notice requirements. The bill modifies existing laws in RSA 374:51 regarding excavation notifications.
