The Implementation Workgroup meeting focused on the Fiscal Year 2026-27 Clean Off-Road Equipment (CORE) Voucher Incentive Project. Key topics included the funding plan, updates to the implementation manual, and programmatic changes to support zero-emission equipment deployment. Specifically, the discussion covered the introduction of six funding categories, the reinstatement of large businesses as eligible purchasers, removal of the disadvantaged/low-income community funding enhancement, new proof of order documentation requirements, and increased flexibility for equipment relocation during emergencies. The meeting also addressed changes to equipment eligibility, including warranty requirement adjustments, expansion of eligible equipment types, and new options for propulsion system installations in commercial harbor craft.

The committee convened to review two significant research proposals. The first proposal, submitted by UC Irvine, focuses on improving estimates of carbon dioxide and methane emissions from Southern California wetlands and updating models for biogenic volatile organic compound emissions to better inform climate and air quality efforts. The second proposal, from UC Davis, aims to validate consumer vehicle choice surveys by integrating survey responses with actual DMV vehicle registration data, a process intended to improve the design, interpretation, and utility of both past and future survey data for air quality planning.

The committee held a meeting to review and provide recommendations on research projects, including draft final reports. Key discussions focused on a project regarding health impact assessment and tracking tools for California communities, and a project concerning the health impacts of filtration improvements in elementary schools. The committee reviewed study methodologies, limitations, and findings related to these air quality and health initiatives, ultimately voting to approve the items after addressing committee feedback and questions.

The committee meeting featured a discussion regarding a research proposal from UC Davis titled Quantifying Green Space Impacts on Human Health in California. Key topics included the methodology for quantifying health benefits and economic impacts of green space, accounting for confounders such as air pollution, heat, noise, and walkability, and the accessibility of these spaces. The committee members provided feedback on managing model uncertainties and the inclusion of wildfire risk considerations in line with state legislative goals. There was also an update on research planning, and the committee confirmed their commitment to utilizing ongoing study databases for modeling.

The committee meeting included the discussion of a contract augmentation regarding the health impacts of wildfires and prescribed burns, with a focus on modeling and emission trade-offs. Additionally, the committee reviewed a draft final report on the health impacts of short-term repeated exposure to wildfire smoke, specifically addressing respiratory and cardiovascular effects, and identified the need for improved policy implications and scientific cohesion in the final report.
