The California Air Resources Board (ARB) invites you to participate in a webinar on Thursday, June 1, 2017 at 10am PDT to discuss updates to the on-road component of the mobile source emission inventory. At the webinar, staff will summarize updates that have been made to EMFAC and present updated methodologies from the upcoming EMFAC2017 model. This will be the first public workshop to discuss the development of the EMFAC2017 model. Slides for the June 1, 2017 workshop have been posted on ARB's public website at: https://www.arb.ca.gov/msei/msei.htm This meeting will be conducted through the GoToWebinar online webinar system and questions from participants will be taken using the webinar software and email.

All times listed above are approximate and will depend on the amount of questions and discussion. -Workshop Information and Background- The past several decades have seen dramatic improvements in air quality as a result of regulations that have reduced emissions from stationary and mobile sources. However, substantial additional emissions reductions will be necessary to meet more stringent ozone air quality standards and California’s long-term greenhouse gas emissions reduction goals. ARB is expanding its mobile source analysis tools to support air quality planning focused on achieving these goals. The EMFAC model is the primary tool ARB uses to assess emissions from on-road vehicles including cars, trucks, and buses. This public webinar workshop will discuss the development of the upcoming EMFAC2017 version of the model. At the webinar, staff will provide a description of the methodologies incorporated and updates made to the model. A subsequent workshop in the fall will cover model estimates and explain differences between the new estimates and those from the prior version of the model, EMFAC2014. -Special Accommodations or Language Assistance- If you require special accommodations or need this document in an alternative format (i.e., Braille, large print) or another language, please contact Mr. Stephen Zelinka at (916) 445-2199, or stephen.zelinka@arb.ca.gov as soon as possible, but no later than 10 business days before the scheduled workshop.
