Bill Overview

Analyzed Economic Effects

3 provisions identified: 0 benefits, 2 costs, 1 mixed.

Excavators and operators face penalties

An underground facility operator or excavator can face a civil penalty of up to $5,000 for missing the required two-business-day notice, breaking a large-project coordination plan, or failing to follow response-system requirements. The penalty applies to the party that violates the rule, not directly to households.

Excavators face new locate rules

Excavators must mark planned work areas in white before requesting location information. This rule does not apply when someone digs on a single-family property they own or occupy. Operators must enter locate responses, such as marked or no conflict, into the response system on time. City and town excavation rules remain in force, and the Arizona Corporation Commission must adopt related rules within one year after the law’s effective date.

Large projects get coordinated marking

A project is large if it exceeds one mile, covers at least one-quarter square mile, lasts more than 90 days, or includes at least 10 connected parcels. New building work on previously undeveloped land is excluded. Large projects require at least 15 business days’ advance notice and a coordination meeting. If the parties cannot agree on a marking schedule, markings are due within 15 business days; following an agreed schedule and using the response system gives excavators a safe harbor for the covered work.
