Committee advances AI provenance bill after amendment debate

The Technology, Economic Development and Veterans Committee voted to report a second substitute of House Bill 1170 out of committee with a do-pass recommendation after extended debate and multiple amendments.

Emily Poole, staff to the committee, described the substitute (HTAC 2,880.1) as a revision that “modifies definitions for AI, covered provider, generative AI, personal information, and system provenance data,” requires covered providers to make available a provenance-detection tool rather than an AI-detection tool, and changes manifest disclosures to identify when content “was AI modified” rather than only AI generated. Poole also said the substitute limits certain private-rights-of-action enforcement so some violations would be enforced only by the attorney general.

Members considered eight amendments. Representative Penner moved an amendment (pool 141) to remove exemptions for public entities and tribal nations so government would be subject to the same standards as private industry; Penner argued the state “should apply it to ourselves” given Washington’s substantial IT footprint. The chair recommended rejecting that amendment and the committee did not adopt pool 141.

Other amendment votes split along policy and implementation lines. Members adopted pool 151 to clarify that providers using “commercially reasonable and industry standard measures” to preserve disclosures would not be considered in violation, a change proponents said would encourage uniform industry standards. The committee adopted pool 146, which sets an effective date of Jan. 1, 2028, to allow alignment with other states’ work. Amendments proposing a right-to-cure (pool 143) and a technical-and-commercial-feasibility safe harbor (pool 152) were debated but not adopted.

During final remarks, supporters framed the bill as a consumer-transparency measure—Representative Shavers said people “deserve to know what they’re seeing or hearing was actually created by generative artificial intelligence”—while others argued the technology is evolving and the bill may be premature. Committee staff called the roll: the final standing committee report showed 7 ayes, 4 nays and 2 excused. By that tally, the second substitute of House Bill 1170 was reported out of committee with a do-pass recommendation.

The report sends the amended measure to the next stage of the legislative process; members and staff indicated further refinement remains possible as the bill moves forward.
