Step-by-step explanation:
The correct answer is option 1 - Not less than 2 or more than 10 days prior to start of excavation. This means that when planning an excavation, notice must be given to each utility owner at least 2 days in advance, but no more than 10 days in advance of the start of excavation.
Proper notice is important to ensure the safety of workers and prevent damage to underground utilities. The utility owners need time to mark the location of their utilities and take any necessary precautions.
Providing adequate notice helps prevent accidents and disruptions during the excavation process. It allows utility owners to plan and prepare accordingly, ensuring the safety of the workers and the integrity of the underground utilities.
