Clean Fleet Enterprise Replace Aging Diesel Trucks

The act authorizes the clean fleet enterprise (enterprise) to incentivize, support, and accelerate the replacement of a truck that is part of a fleet and that is powered by a diesel-fueled internal combustion engine, is a model year of 2009 or earlier, and is registered, operable, and capable of independent roadway operation (aging diesel truck) with a diesel truck that is a model year of 2018 or later (new diesel truck) until December 31, 2031.

What This Bill Does

The act authorizes the clean fleet enterprise (enterprise) to incentivize, support, and accelerate the replacement of a truck that is part of a fleet and that is powered by a diesel-fueled internal combustion engine, is a model year of 2009 or earlier, and is registered, operable, and capable of independent roadway operation (aging diesel truck) with a diesel truck that is a model year of 2018 or later (new diesel truck) until December 31, 2031.
The act also allows the enterprise to provide funding or financing through grant programs, rebate programs, revolving loan funds, or other strategies to help owners and operators of aging diesel truck fleets finance the replacement of aging diesel trucks with new diesel trucks to reduce the up-front costs of acquiring new diesel trucks until December 31, 2031.
The enterprise may use the clean fleet enterprise fund to provide money to support the replacement of aging diesel trucks with new diesel trucks, but the enterprise is required to ensure that it does not expend more than 20% of the fund's income during a state fiscal year for the support.
To qualify for any money provided by the enterprise for the replacement of aging diesel trucks with new diesel trucks, the act requires a purchaser of the new diesel truck to surrender an aging diesel truck to the seller of the new truck.

Official Summary Text

The act authorizes the clean fleet enterprise (enterprise) to incentivize, support, and accelerate the replacement of a truck that is part of a fleet and that is powered by a diesel-fueled internal combustion engine, is a model year of 2009 or earlier, and is registered, operable, and capable of independent roadway operation (aging diesel truck) with a diesel truck that is a model year of 2018 or later (new diesel truck) until December 31, 2031. The act also allows the enterprise to provide funding or financing through grant programs, rebate programs, revolving loan funds, or other strategies to help owners and operators of aging diesel truck fleets finance the replacement of aging diesel trucks with new diesel trucks to reduce the up-front costs of acquiring new diesel trucks until December 31, 2031.
The enterprise may use the clean fleet enterprise fund to provide money to support the replacement of aging diesel trucks with new diesel trucks, but the enterprise is required to ensure that it does not expend more than 20% of the fund's income during a state fiscal year for the support.
To qualify for any money provided by the enterprise for the replacement of aging diesel trucks with new diesel trucks, the act requires a purchaser of the new diesel truck to surrender an aging diesel truck to the seller of the new truck. The seller of the new diesel truck must decommission the aging diesel truck by drilling a hole in the engine's block and cutting the chassis rails in half. The seller must be an authorized dealer of new diesel trucks who must certify that the new diesel truck meets all state and federal emissions and safety standards for its model year.
The enterprise must prioritize applications to replace aging diesel trucks from businesses that are privately owned, independently owned, or have limited access to capital. The enterprise is not allowed to accept an application from the owner or operator of a motor vehicle fleet that owns, leases, or operates more than 50 heavy-duty motor vehicles or from a business entity with annual gross revenue exceeding $100 million. The enterprise is required to prioritize the replacement of an aging diesel truck that has a model year of no later than 2006.
The act expands the business purpose of the enterprise to include providing incentives and support for refrigerated transport units powered by zero emission technology. The act allows the enterprise to exercise its rights and powers without regard to the state 'Procurement Code'.
The act requires the enterprise to annually prepare a report that includes the estimated pollution reduction benefits of the enterprise. The enterprise must seek to ensure that all projects funded by the enterprise achieve measurable results and outcomes.
