SB1137 revises Arizona’s underground facilities damage-prevention law, which governs how excavators, utilities, landlords, and property owners locate and protect buried infrastructure before digging. The bill expands and modernizes the notice-and-marking process by requiring white lining before locate requests, creating a new “interactive positive response system” for electronic status updates, and establishing special procedures for “large projects” that exceed certain size or duration thresholds. It also adds a new statutory section directing the one-call notification center to adopt written procedures and minimum technical and data security standards for the new system.
The bill also updates who must mark underground facilities and how. It clarifies duties for underground facilities operators, landlords in apartment communities and mobile home parks, sewer-system operators, homeowners, and tenants, including rules for abandoned or apparently abandoned facilities, detectible underground location devices on newer installations, and liability limits in certain circumstances. It preserves existing requirements that excavators act carefully and prudently, but it adds more detailed coordination, documentation, and communication requirements for both standard excavations and large projects.
In terms of state law, SB1137 amends multiple sections of Title 40, chapter 2, article 6.3, including definitions, excavation procedures, liability provisions, and civil penalties. It also authorizes the one-call notification center, in consultation with the Arizona Corporation Commission and stakeholders, to implement the new procedures within one year. The bill maintains civil penalties of up to $5,000 for violations, while also creating specific liability rules for failures to notify, mark, coordinate, or use the interactive system as required.
The general sentiment around the bill appears favorable. It advanced through both chambers with strong committee support and passed the Senate and House on third reading by comfortable margins, then was signed into law. The voting history suggests broad agreement that the bill updates and improves excavation safety and utility coordination, especially for larger and more complex projects.
The main points of contention are likely operational rather than ideological. The bill imposes new compliance duties on excavators, landlords, and utility operators, including mandatory white lining, tighter coordination timelines, and use of a new electronic response platform. Potential concerns would center on implementation costs, administrative burden, data/security requirements, and whether the new procedures are workable for landlords, utilities, and contractors on large or time-sensitive projects. The bill’s detailed liability and exemption provisions also suggest attention to disputes over who bears responsibility when underground facilities are damaged or records are incomplete.
SB1137 amends Arizona’s underground facilities damage-prevention statutes in Title 40 by adding new definitions, new excavation and marking procedures, new large-project coordination requirements, and a new section directing the one-call notification center to establish implementation procedures and technical/data security standards. It affects excavators, underground facilities operators, landlords, sewer-system operators, homeowners, homeowners’ associations, tenants, local jurisdictions, and the Arizona Corporation Commission’s regulatory framework, while preserving civil penalties and liability rules for noncompliance.
The bill’s overall reception was positive and bipartisan in the recorded votes. It cleared Senate and House committees and passed both chambers by substantial margins, indicating broad support for updating excavation safety and utility-locating rules. The final enactment and signature suggest the legislature and governor viewed the measure as a practical infrastructure and public-safety update rather than a controversial policy shift.
The likely areas of contention are the bill’s new compliance obligations and implementation details. Excavators must white-line excavation areas before requesting locates, large projects must follow a coordination process with phased ticketing and an interactive response system, and landlords and utilities face more explicit marking and response duties. Stakeholders could disagree over the cost and feasibility of these requirements, the adequacy of the one-call center’s technology and security standards, and the allocation of liability when markings are delayed, records are incomplete, or facilities are abandoned or difficult to verify.
