Purpose of the Workshop

The workshop will provide an overview of proposed updates to methodologies found in the following major source categories:

• Commercial Cooking
• Dairy/Livestock Waste; Feedlot Dust
• Silage
• Soil NOx and NH3
• Farming Operations Dust
• Unpaved Farm/Non-farm Road Dust
• Paved Road Dust
• Windblown Dust
• Building/Road Construction Dust
• Residential Wood Combustion
• Residential Waste Burning
• Domestic Ammonia
• Stationary Diesel Engines

These updates are being made to improve the accuracy of emissions data used in statewide, regional, and community-scale air quality planning. They reflect new activity data, updated emission factors, and recent scientific studies. Detailed information on existing methodologies can be found on CARB’s Index of Methodologies by Major Category. Slides of the workshop will be made available on our webpage prior to the workshop.

Participants will be able to engage in an active discussion during the Zoom meeting and can also send written questions or comments to CARB staff. If you have questions about the meeting purpose, scope and logistics, please contact the Area Source Inventory Team.
