MODERATE

This bill was amended to clarify that only counties, not the state itself, are required to upgrade to zero-emission buses by 2045. The state's role was changed to a priority guideline for purchasing vehicles. Additionally, the effective date for the entire act was delayed from immediate approval to July 1, 2050.

Scope change

The requirement to switch to zero-emission buses was narrowed from applying to both the state and counties to applying only to counties; the state now only has a procurement priority.

REQUIREMENT

The mandate to upgrade to zero-emission buses by 2045 was removed from the state and applied only to counties.

State agencies were added a new requirement to prioritize zero-emission buses in their vehicle procurement policies.

TIMELINE

The effective date of the Act was changed from immediate approval to July 1, 2050.

DEFINITION

Definitions for terms like 'Agency' and 'Zero-emission vehicle' were expanded to align with federal regulations and include specific vehicle categories.
