§ 50. Executive Order No. 10-50 (No. 04-25) [Advanced Clean Trucks, Advanced Clean Cars II, and Heavy-Duty Engine

  • and Vehicle Omnibus] WHEREAS, in December of 2022, Vermont adopted the Advanced Clean Cars II (ACC II),
    Advanced Clean Trucks (ACT), and Heavy-Duty Engine and Vehicle Omnibus (HD Omnibus)
    rules, pursuant to Section 177 of the federal Clean Air Act; and WHEREAS, the ACC II and ACT rules require original equipment manufacturers (OEMs or
    manufacturers) of passenger cars and light-duty trucks and on-road medium- and heavy-duty
    vehicles to produce and deliver for sale an increasing percentage of zero emission
    vehicles (ZEVs) starting in Model Year 2026; and WHEREAS, the framework for the ACC II and ACT rules are intended to accelerate the
    transition to ZEVs, give Vermonters and Vermont businesses more options, protect public
    health and air quality, and reduce greenhouse gas emissions; and WHEREAS, the HD Omnibus rule is intended to protect public health and air quality
    and requires manufacturers of on-road heavy-duty vehicles with gross vehicle weight
    ratings (GVWR) greater than 10,000 pounds to meet more stringent emission standards
    for nitrogen oxides (NOx) and particulate matter (PM) and to enhance warranty periods,
    useful life, and durability of applicable engines starting in Model Year 2026; and WHEREAS, it has become clear that there is insufficient charging infrastructure for
    passenger cars and insufficient technological advances in heavy-duty vehicles for
    these regulatory requirements to meet current goals; and WHEREAS, tariffs and other federal disruptions are increasing costs and causing supply
    chain uncertainty; and WHEREAS, some manufacturers are shifting the burden of the ACC II and ACT rules to
    local auto dealers by requiring ZEV sales before allowing internal combustion engine
    car and truck sales (hereinafter referred to as “ZEV sales ratios”), which reduces
    the number and type of internal combustion engine cars and trucks available to Vermont
    dealerships and customers; and WHEREAS, some manufacturers are requiring ZEV sales before allowing internal combustion
    engine truck sales to generate nitrogen oxide credits in lieu of HD Omnibus-compliant
    engine sales to meet HD Omnibus requirements, again resulting in reduced availability
    of internal combustion engine trucks to Vermont dealerships and customers; and WHEREAS, my Administration remains committed to achieving emissions reductions, including
    vehicle emissions, I have determined compliance flexibility and enforcement discretion
    are needed to ensure Vermonters will continue to be able to acquire the full range
    of passenger cars and light-duty trucks and on-road medium- and heavy-duty vehicles
    in sufficient numbers to satisfy demand and avoid counterproductive impacts. NOW THEREFORE, pursuant to the authority vested in me as Governor of the State of
    Vermont by the Constitution of the State of Vermont, Chapter II, Section 3 and Section
    20, 10 V.S.A. § 554, and 10 V.S.A. § 551, I HEREBY ORDER the Vermont Department of Environmental Conservation (Department)
    shall use its enforcement discretion as necessary to ease compliance with ACC II and
    ACT standards, including but not limited to, the following: (a) For the ACT and HD Omnibus sales requirements, provided that manufacturers do not
    impose ZEV sales ratios on dealerships in Vermont and provided that manufacturers
    supply internal combustion engine on-road medium- and heavy-duty vehicles to dealerships
    seeking those vehicles, the Secretary of the Agency of Natural Resources (ANR), shall
    utilize compliance flexibility and exercise enforcement discretion by not taking action
    against manufacturers that do not meet their sales obligations for the duration of
    this order. ANR shall establish an email box dedicated to receiving complaints from those who
    believe manufacturers are imposing ZEV sales ratios on dealerships in Vermont. ANR
    and the Department shall post this contact information prominently on their websites,
    together with instructions on required information, including make, model, model year
    and number of vehicles. ANR shall evaluate the information provided to determine if a manufacturer remains
    eligible for the compliance relief provided by this order; and (b) For the ACC II ZEV sales requirements, the Secretary of ANR shall exercise compliance
    flexibility and enforcement discretion by declining to pursue penalties associated
    with any ZEV delivery shortfalls for the duration of this order. To be eligible for
    compliance relief, manufacturers must not impose ZEV sales ratios on dealerships in
    Vermont and must fulfill in a timely manner all requests for vehicles to dealerships
    seeking those vehicles. ANR shall require each manufacturer to provide to the Secretary, by July 1, 2025 and
    July 1, 2026, reports detailing efforts to promote and market ZEVs such as increasing
    deployment of charging infrastructure including investments in fast charging, level
    2 charging and home charging options; educating and training dealerships including
    sales and service staff on ZEVs; and providing ZEVs for ride and drive events. Nothing in this Executive Order is intended to conflict with applicable State or federal
    law. This Executive Order 04-25 shall take effect upon signing and shall continue in full
    force and effect until December 31, 2026, or until the Governor, in consultation with
    the Secretary of ANR, determines whether to amend or rescind this Order. Dated May 13, 2025.
