Senate adopts bill to increase transparency of PUC rail incident reports after narrow amendment

The Colorado Senate on Feb. 3, 2025 approved Senate Bill 52, a measure to make certain Public Utilities Commission (PUC) investigative reports on rail incidents more transparent, and approved amendment L001, which replaced the bill’s safety clause with a petition clause and included an effective-date provision.

The bill, introduced on the floor by a member of the Senate and moved for consideration by Senator Hamilton, was described by sponsor Senator Winter as aimed at increasing public access to PUC investigative reports that are not required to remain confidential.

"This does add transparency and we are the only state in the country that does not have this transparency. And so I encourage a yes vote," Senator Winter said on the floor.

Senator Simpson, who spoke in opposition, said the change to confidentiality rules risked public safety and posed questions about how much investigative material should be public. "For me, it felt like this was just pushing it too far that we were sacrificing public safety in this space in lieu of more transparency," Simpson said, noting a prior committee "no" vote.

The chamber considered and adopted amendment L001, which the sponsor accepted. The amendment removed the bill’s safety clause and substituted a petition clause; the clerk read an effective-date provision as part of the amendment. The motion to adopt amendment L001 passed by voice vote.

Senator Baselick raised a question about security-related material in investigative reports and whether publication could expose vulnerabilities that someone with nefarious intent might exploit. The sponsor responded that the bill delegates rulemaking authority to the PUC to define what constitutes security-sensitive information and to withhold it where appropriate.

Senate Bill 52 as amended passed the Senate by voice vote and was ordered engrossed. The floor record shows the passage by voice vote; no numerical roll-call tally for final passage was recorded on the floor transcript.

Why it matters: the bill changes the balance between transparency and confidentiality for PUC-ordered investigations under current statute (Title 40, Article 18, §10104). Sponsors and backers said the change will give transit agencies, riders and local leaders more information about incidents and agency responses; opponents warned of potential security and safety trade-offs and sought safeguards via the PUC rulemaking process.

What happens next: Senate Bill 52, as amended, will proceed according to normal legislative steps; rulemaking direction in the bill leaves the PUC responsible for defining and protecting security-sensitive material before public release.
