What is the maximum number of calendar days allowed between the notice to Underground Service Alert Center and the start of excavation?

• A. 7
• B. 14
• C. 21
• D. 28

Answer: (B)

When you file a notice with the Underground Service Alert Center, the protection it provides lasts for a fixed window of time: fourteen calendar days. You must begin excavation within those fourteen days, or you’ll need to submit a fresh notice to refresh the protections and recheck the utility markings. This 14-day limit helps ensure the marks and information remain current and that the digging project proceeds with up-to-date safety information. The other day counts (7, 21, or 28) don’t align with this standard window, so they aren’t the correct duration.
