ARIZONA STATE SENATE

Fifty-Seventh
Legislature, Second Regular Session

AMENDED

FACT SHEET FOR
S.B. 1137

underground
facilities; excavations; notification

Purpose

Modifies the requirements under the Underground Facilities Statutes for
excavators

and underground facilities operators
to coordinate the location and marking of underground facilities.

Background

In 1973, the Legislature established the Underground Facilities Statutes
outlining procedures for underground facilities owners and operators to be
notified in advance of excavations that may affect underground facilities.
Subsequently in 1974,
Arizona Blue Stake
was established as the one-call
notification center for underground facility owners and operators to coordinate
digging plans and excavation markings in accordance with statute. In 2014, the
center was renamed to
Arizona 811
, still acting as the one-call
notification center (
Laws
1973, Ch.57
;
Arizona811
).

Current statue prohibits a person from making or beginning any excavation
in any public street, alley, right-of-way, outlined utility easement, apartment
community or mobile home park without first determining whether underground
facilities will be encountered and if so where they are located. For all
excavations in an apartment community or mobile home park, the excavator must
inform the landlord as promptly as practical that the excavator intends to
submit an inquiry to the landlord that will trigger the landlord's inquiry
notification obligations. On a timely request by the underground facilities
operator, the excavator must mark the boundaries of the area requested to be
excavated in accordance with a color code designated by the Arizona Corporation
Commission (ACC) or by applicable customs or standards in the industry. Upon
receipt of the excavator's inquiry, the underground facilities operator must
respond as promptly as practical, but no later than two working days, by
carefully marking such facilities with stakes or paint or in some customary
manner. A landlord must respond in the same manner and as promptly as
practical, but no later than 10 working days. A person may not begin excavating
before the location and marking are complete or the excavator is notified that
marking is unnecessary (
A.R.S.
� 40-360.22
).

A person who violates any provision of the Underground Facilities
Statutes is subject to a civil penalty of up to $5,000 to be imposed by the
court in favor of the state. Any penalties received by the state must be
deposited in the state General Fund (‎
A.R.S.
� 40-360.28
).

There is no anticipated fiscal impact to the state General Fund
associated with this legislation.
