end
Requested Action(s)
recommendation
a) PUBLIC HEARING - Conduct a public hearing to receive comments on the proposed adoption of the Northern Sacramento Valley Planning Area 2024 Air Quality Attainment Plan
b) Consider adoption of a finding that the adoption of the Northern Sacramento Valley Planning Area 2024 Air Quality Attainment Plan, which is a regulatory activity to assure the protection of the environment, is categorically exempt from review under the California Environmental Quality Act (Class 8 Categorical Exemption), and direction to the Air Pollution Control Office to file a Notice of Exemption
c) RESOLUTION - Request adoption of a resolution adopting the Northern Sacramento Valley Planning Area 2024 Air Quality Attainment Plan
OR
d) Propose changes to the text of the Northern Sacramento Valley Planning Area 2024 Air Quality Attainment Plan, and re-schedule the public hearing to consider the proposed Rule as revised
OR
e) TAKE NO ACTION - Taking no action will hinder the Districts efforts in attaining State Ambient Air Quality Standards for ozone by the earliest practicable date

Background Information:
The California Clean Air Act (CCAA) requires air districts which have been designated as a nonattainment area for California Ambient Air Quality Standards (CAAQS) for ozone, carbon monoxide, sulfur dioxide, or nitrogen dioxide to prepare and submit a plan for attaining and maintaining the standards. The CCAA also requires that districts review their progress made toward attaining the CAAQS every three years.
The Air Pollution Control Districts and Air Quality Management Districts (Districts) for the counties located in the northern portion of the Sacramento Valley together encompass the Northern Sacramento Valley Planning Area (NSVPA). The NSVPA air districts of Butte, Colusa, Glenn, Shasta, Sutter, Tehama, and Yuba counties have agreed to jointly prepare an Air Quality Attainment Plan. Glenn and Colusa Counties are in Attainment but continue to participate in the regional effort.
The 2024 triennial update of the NSVPA Air Quality Attainment Plan (2024 Plan) assesses the progress made in implementing the previous triennial update and proposes modifications to the strategies necessary to attain the CAAQS by the earliest practicable date. The 2024 Plan includes an assessment of progress towards achieving the control measure commitments in the previous Triennial Plan, a summary of the last three years of ozone data, a comparison of the expected versus actual emission reductions for each measure committed to in the previous Triennial Plan, updated control measure commitments, and updated growth rates of population, industry, and vehicle related emissions.
In the NSVPA, ozone can be caused by stationary source emissions, such as from internal combustion engines or boilers, mobile sources such as cars, trucks, and trains, or area sources such as consumer products or wildfires. The NSVPA districts also experience transport ozone from the Broader Sacramento Area (BSA), which comprises all of the Sacramento Metropolitan AQMD, Yolo-Solano AQMD, and a portion of El Dorado, Placer, and Sutter Counties. Emissions that were originally created in the BSA can be transported northward via prevailing winds to affect the pollution levels of the NSVPA.
The 2021 to 2023 monitoring data shows a decrease in 8-hour ozone exceedances and an increase in 1-hour ozone exceedances of the CAAQS compared to the 2018-2020 monitoring data. Wildfires continue to be a contributor to these exceedances. ROG and NOx emissions are projected to decrease, with mobile sources accounting for 60% of the NOx emission inventory and area-wide sources account for 44% of the ROG inventory in 2025. In the past three years the Carl Moyer and FARMER programs have resulted in reducing 222 tons of NOx and 24 tons of ROG. The NSVPA Districts also fund emission reduction projects through AB 617 Community Air Protection Programs, AB 2788/AB 923 Vehicle Fee Programs, Wood Stove Changeout Programs, and Off-Road Voucher Incentive Programs.
