House Transportation revisits Advance Clean Cars 2; staff details warranties, recycling, charging and dealer concerns

Montpelier ' Vermont Agency of Natural Resources staff returned to the House Committee on Transportation on Wednesday, Feb. 12, to resume testimony on the state's adoption of the Advance Clean Cars 2 regulation and to answer detailed questions about consumer protections, battery recycling, charging infrastructure, dealer impacts and workforce support.

The briefing recapped the rulemaking adopted in 2022, described benefits the agency identifies for Vermonters, and summarized state and federal funding and training programs meant to ease the transition to electric vehicles (EVs). Agency staff said the model-year compliance timeline begins in 2026.

Why it matters: Transportation is the largest source of greenhouse gas emissions in Vermont, the agency said, and Advance Clean Cars 2 (adopted identical to California's standard under Clean Air Act Section 177 procedures) requires manufacturers to deliver increasing shares of zero-emission vehicles. While the regulation directly binds manufacturers, the committee focused on indirect local impacts for consumers, dealers, repair shops, fleet operators and charging networks.

Agency overview and consumer protections Agency of Natural Resources General Counsel Rachel Stevens told the committee the regulation's principal public benefits are lower greenhouse-gas emissions and improved air quality. "The primary benefit of the regulation is the reduction in greenhouse gas emissions and the improvements in air quality," Stevens said during the session.

Stevens and technical staff noted specific consumer protections in the adopted California-based standard that exceed federal basic warranties: a battery warranty requirement of eight years or 100,000 miles (whichever comes first) and, for plug-in hybrids, an emissions warranty of 15 years or 50,000 miles. By contrast, the federal emissions warranty referenced in committee testimony is two years or 24,000 miles; federally required coverage for catalytic converters and engine control systems was described as eight years or 80,000 miles.

Battery life, recycling and sourcing questions Committee members and public commenters pressed staff on end-of-life battery handling and upstream mining. Stevens said Advance Clean Cars 2 includes recycling and labeling requirements intended to make second-life uses and recycling easier, and the agency noted that materials within batteries are commercially valuable and that the recycling market is still emerging.

The committee asked about where battery raw materials are mined. Agency staff said they cited lifecycle analyses in their technical support documents and in the rulemaking record showing that, even when accounting for manufacturing and end-of-life impacts, EVs have lower lifetime emissions than comparable internal-combustion vehicles. Staff also directed members to the responsiveness summary included in the administrative record for additional detail on mining and recycling questions; an outside group referenced in testimony (identified in the record as NESCOM) is preparing a report on battery lifecycle issues.

Charging infrastructure and usage Agency staff summarized publicly available charging infrastructure data and state investments. They cited National Renewable Energy Laboratory (NREL) guidance and Vermont metrics: NREL recommends roughly 40 level-2 plugs per 1,000 EVs; Vermont was reported at about 56.3 level-2 plugs per 1,000 EVs. For direct-current fast chargers (DCFC), NREL's recommended ratio is about 3.4 DCFC per 1,000 EVs; staff said Vermont reported roughly 11.4 DCFC per 1,000 EVs. The agency said more than 80% of EV charging typically occurs at home and described pilot and utility efforts such as vehicle-to-grid trials.

State programs and funding cited by staff include the 2023 Charge Vermont initiative (administered by the Agency of Commerce and Community Development with Green Mountain Power), which staff said contracted roughly $7 million for charging at multifamily, workplace and public locations; the Agency of Transportation's work to date, which the agency said has supported more than $3.5 million in fast-charging investments on Vermont highway corridors since 2014; and Volkswagen settlement (Mitigation Trust) funding administered for medium and heavy-duty electrification, which staff described as roughly $3 million to $5 million available for fleet projects and diesel-emission reductions.

Costs, total cost of ownership and incentives Staff pointed the committee to the technical support documents included in the 2022 rulemaking record for lifecycle and economic analyses. The agency described factors included in total-cost-of-ownership comparisons: potential outlet upgrades for home charging, lower fuel-equivalent electricity costs (staff cited examples of an electricity-per-gallon gasoline equivalent near $1.75 to $2.00 in some analyses), and lower routine maintenance because EVs have fewer moving parts.

Staff also described programs for fleets and dealers: an Electrify Your Fleet rebate (testimony described rebates up to $2,500 and capped at no more than 25% of a vehicle's purchase price), utility and federal incentives, and dealer-focused readiness and sales-incentive programs run by Drive Electric Vermont and Efficiency Vermont.

Dealer, technician and workforce concerns Several legislators and commenters raised concerns about dealers being "forced" to sell EVs, availability of appropriate trucks for heavy-duty work, and technician retraining. Representative Welt criticized manufacturer practices and asserted that some dealers were being required to take EVs they could not sell. Stevens and staff said the regulation requires manufacturers to deliver compliant vehicles but does not force individual businesses to purchase vehicles; they added that some manufacturer-imposed dealer practices (for example, internal ratio targets) go beyond regulatory requirements and that the agency is engaging manufacturers about compliance choices.

For medium- and heavy-duty vehicles the agency emphasized that Advanced Clean Trucks is a separate regulation from Advance Clean Cars 2 and that sales targets and compliance timelines for trucks are less aggressive to reflect technology and market differences. Staff identified practical early-use cases for medium-duty electrification (local delivery, depot-charged vehicles, some transit and school-bus pilots) and listed recent VW-funded awards for utility bucket trucks, refrigerated box trucks and a few refuse and municipal vehicles.

Right-to-repair and independent servicing Agency staff said Advance Clean Cars 2 contains requirements that manufacturers provide service and repair information to independent shops so that independent mechanics can service EVs. The agency also pointed to state-sponsored technician trainings and partner programs (Vermont Clean Cities Coalition, Efficiency Vermont) intended to reduce workforce transition barriers.

Implementation process and legal context Stevens reminded the committee that Vermont adopted the California standard through the Administrative Procedure Act process and that the Global Warming Solutions Act directed the agency to review and consider such regulations. Staff also told members that Section 177 of the Clean Air Act allows other states to adopt California standards, and they noted a citizen-enforcement provision in Vermont's climate statute that can create legal exposure if required regulatory steps are not completed.

What's next Agency staff said they would follow up with committee members by sharing cited technical reports, the responsiveness summary from the 2022 record, and links to practitioner resources. Multiple legislators asked staff to provide additional, more focused lifecycle and cost documents and to clarify manufacturer-dealer practices they had observed during stakeholder outreach.
