The One-Call representative will notify participating utility companies of your proposed digging activities.
Utilities will then mark their underground facilities by using the following international marking codes:
OSHA CFR 29 1926.651
requires that the estimated location of underground utilities be determined before
beginning excavation or underground drilling operation. When actual excavation or bore approaches an
estimated utility location, the exact location of the underground installation must be determined by a safe,
acceptable and dependable method. If utility cannot be precisely located, it must be shut off by the utility
company.
