• A. Underground Service Alert

Answer: (D)

Before starting any digging, you must contact the local utility location service so they can locate and mark all underground lines in the work area. In Arizona, that program is Bluestake. Bluestake serves as the single point of contact to notify all utility owners, who then come out to locate and mark their lines, helping you dig safely around them. While Underground Service Alert and One Call Center describe similar services in other states, Bluestake is the official program you use in this state, which is why it’s the correct choice here. After you call, you’ll typically receive a ticket number, and the utilities will mark lines with paint or flags using color codes that indicate the type of utility (for example, electric, water, gas). Do not dig where markings are present until you have explicit clearance.
