California Assembly Advances SB 804 Hydrogen Safety Bill

California's Assembly moved dedicated hydrogen pipelines a step closer to one clear safety regulator this year. Lawmakers advanced Senate Bill 804, which names the Office of the State Fire Marshal as the enforcement authority. The measure closes a gap regulators have flagged for years and sets a January 1, 2028 deadline for enforceable standards.

What Does SB 804 Do for Hydrogen Pipeline Safety?

SB 804 gives one state agency clear jurisdiction over hydrogen-dedicated pipelines. It directs the Office of the State Fire Marshal to write hydrogen-specific rules rather than stretching existing gas pipeline codes to fit a different molecule.

The bill requires continuous leak monitoring systems on covered pipelines. Owners must design and build lines to keep hydrogen leakage at the lowest technically feasible level.

Reporting duties follow the same clear line. Operators submit an annual compliance report to the office by March 30, covering concentration data and any confirmed leaks from the prior year.

None of this authorizes new pipeline construction on its own. The bill sets the safety rulebook first. If hydrogen infrastructure gets built in California, it operates under one accountable standard. Senator Archuleta made that point directly to the committee.

Why Does the Bill Return Oversight to the State Fire Marshal?

SB 804 did not start out this way. Earlier versions assigned the standard-setting job to the California Public Utilities Commission, with the California Energy Commission enforcing rules on private, intrastate lines.

That version carried a real price tag. The CPUC estimated one-time costs of about $2.2 million a year for three years through 2028 to write and enforce those standards. That figure comes from the Senate Appropriations Committee's May 19, 2025 analysis.

Lawmakers and the author's office reworked the bill after last year's committee hearing. They worked with the Governor's office and the fire marshal's staff on the change. The result moved enforcement authority back to the OSFM, the agency already certified as California's federal pipeline safety partner.

Industry witnesses backed the shift, framing clear jurisdiction as good for both safety and the pipeline trades building this infrastructure. Not every stakeholder is fully on board with the current language though. Air Products has raised specific concerns about scope, even while supporting the bill's underlying intent.

SB 804 Compared With California's Carbon Pipeline Law

California passed a related pipeline measure last year covering a different molecule entirely. Both bills land on the same regulator, which suggests the state is settling on the Office of the State Fire Marshal as its go-to safety authority for decarbonization infrastructure.

Bill	Molecule / Focus	Regulator Named	Status
SB 804 (Archuleta)	Dedicated hydrogen pipeline safety standards	Office of the State Fire Marshal	Advancing through Assembly committees, 2026
SB 614 (Stern)	Dedicated CO2 pipelines for carbon storage transport	Office of the State Fire Marshal	Signed into law, October 10, 2025

What Happens Next for SB 804?

The bill has already cleared two Assembly policy committees this year. The Assembly Utilities and Energy Committee heard the amended version on June 24, 2026. The Assembly Emergency Management Committee voted it out to the Committee on Appropriations five days later, on June 29, 2026.

That appropriations stop is standard for any bill carrying fiscal impact, and SB 804 is keyed fiscal. The Assembly Utilities and Energy Committee's original 18 to 0 vote in June 2025 signals the bipartisan support the author has built across two sessions.

If SB 804 clears Appropriations and both floor votes, the fire marshal's office would have until January 1, 2028 to finalize standards. That timeline lines up with California's broader buildout of hydrogen hub infrastructure. It also gives pipeline developers, including those working on projects like Chevron's California hydrogen initiatives, a firm date to design toward.

The state's carbon side offers a useful preview of what regulatory clarity can unlock. California's first commercial carbon storage project broke ground within a year of its enabling framework taking shape. The site now holds 38 million metric tons of total storage capacity. A settled hydrogen pipeline rulebook could support similar progress on the California DAC Hub consortium and other state-backed carbon management hub work already underway.

Setting the Rulebook Before the Pipelines Go In

Senator Archuleta's argument to the committee was straightforward. Establishing safety rules before infrastructure gets built costs less than retrofitting a system afterward.

SB 804 still needs to clear Appropriations and both chambers before that rulebook becomes law. It has an 18 to 0 committee vote on the books, plus two more committee approvals this year. That's the kind of bipartisan track record that tends to carry a bill to the Governor's desk.
