Concerning the replacement of certain catalytic converters.
Summary
HB 26-1199 creates a temporary exception to Colorado’s catalytic-converter replacement requirements when a converter is stolen or mechanically fails and a compliant replacement is unavailable. Under current air-quality rules, replacement catalytic converters generally must meet California Air Resources Board standards; this bill would allow use of a replacement that meets U.S. Environmental Protection Agency standards instead, but only if the theft is reported to law enforcement, the owner or operator makes a reasonable effort to obtain a compliant replacement and cannot get one, and the vehicle passes an emissions inspection within 30 days after installation.
The bill also directs the Air Quality Control Commission to adopt implementing rules by October 1, 2026, and it sunsets the exception on July 1, 2028. In addition, it amends the law governing motor vehicle repair facilities to prohibit a repair shop, employee, or contract laborer from repairing or replacing a stolen or failed catalytic converter without first informing the customer about available state programs to replace an internal combustion vehicle with a zero-emission alternative, including the Vehicle Exchange Colorado program.
The bill’s impact is narrow but significant for drivers, repair facilities, and emissions compliance enforcement. It temporarily relaxes the replacement standard for certain catalytic converters, potentially reducing delays and costs for vehicle owners who cannot obtain a California-compliant part, while preserving emissions oversight through reporting, documentation, and post-installation inspection requirements. It also adds a consumer-notice obligation for repair businesses regarding state incentives for switching to zero-emission vehicles.
The available legislative context suggests the bill had mixed or limited support. The bill advanced through the House Energy & Environment committee, but the last recorded action shows it was laid over in House Appropriations and an amendment failed, indicating unresolved concerns or insufficient support at that stage. No vote tally or transcript is provided, so the overall sentiment can only be characterized as cautious and procedural rather than clearly enthusiastic or opposed.
The main point of contention appears to be the balance between air-quality regulation and practical availability of replacement parts. Supporters likely view the bill as a temporary, targeted fix for theft and supply shortages, while critics may be concerned that allowing EPA-standard converters instead of California-standard converters could weaken emissions protections or create enforcement complexity. The repair-shop notice requirement may also be seen as either a consumer-information measure or an added burden on businesses.
Impact
The bill would add a new temporary exception to Colorado motor-vehicle emissions law, specifically overriding existing requirements tied to Article 7 of Title 25 and related Air Quality Control Commission rules for certain catalytic-converter replacements. It would also amend the prohibited-acts statute for motor vehicle repair facilities to require disclosure of state zero-emission vehicle replacement programs before repairing or replacing a failed or stolen catalytic converter. The Air Quality Control Commission would need to adopt implementing rules, and the exception would automatically repeal in 2028.
Sentiment
Based on the limited legislative history provided, the bill appears to have generated cautious, mixed sentiment. It moved in committee but later stalled at Appropriations with an amendment failing, suggesting that lawmakers saw a real problem to address but had not fully resolved policy or implementation concerns. No recorded votes or transcript comments are available, so there is no evidence of strong consensus either for or against the measure.
Contention
The central contention is whether Colorado should temporarily relax its catalytic-converter replacement standard from California-compliant parts to EPA-compliant parts when replacements are unavailable. Supporters are likely focused on theft-related hardship, supply shortages, and getting vehicles back on the road; opponents may worry about emissions impacts and weakening a stricter state standard. A secondary point of contention is the new requirement that repair facilities inform customers about zero-emission vehicle replacement programs, which may be viewed as useful consumer outreach or as an added regulatory obligation on shops.
