LACEY—Starting July 27, 2025, Washington’s revised dig law (RCW 19.122) will introduce stricter regulations and higher penalties to enhance safe excavation practices and protect underground utilities. The changes, unanimously passed by the state Legislature and signed by Governor Bob Ferguson, aim to prevent pipeline damage and ensure safer digging for utilities, contractors, and homeowners.
“These changes are intended to improve safe excavation practices and prevent damage to underground utilities,” according to the announcement from the Washington Utilities and Transportation Commission (UTC).
A key update grants the UTC Pipeline Safety Program expanded enforcement authority over violations involving gas and hazardous liquid pipelines. Civil penalties for damaging such pipelines have increased significantly, with fines now reaching up to $25,000.
Additionally, violations that do not result in damage may incur penalties of up to $5,000. The law also clarifies responsibilities for utilities and excavators, emphasizing safe digging methods.
“The law clearly outlines what utilities and excavators must do and encourages safe digging methods,” the UTC stated.
Another change mandates design locates for any development within 700 feet of a transmission pipeline, ensuring early identification of underground facilities. Starting January 1, 2026, excavators must receive a “positive response” from all operators with underground facilities in the excavation area before beginning work. This requirement aims to enhance coordination and safety. The existing rule to mark excavation areas with white lines and maintain locate marks for up to 45 days remains unchanged, with a new locate required after this period.
The UTC continues to urge anyone planning to dig to contact 811 or visit callbeforeyoudig.org at least two but no more than 10 business days before starting work.
“The call and locates are free to the excavators,” the UTC stated, highlighting that this service helps prevent injuries, outages, and costly repairs.
The UTC Pipeline Safety Program, established in 1955, oversees safety for 41 pipeline operators and inspects over 47,000 miles of pipelines across Washington. Additional details are available at utc.wa.gov/diglaw.
