Applying electronically via CalCareers is highly recommended. If submitting a hardcopy application (mail/drop-off), please send an email to Essam.Gad@arb.ca.gov to confirm submission.

The On-Road Model Development Section (ORMDS) is recruiting for an Air Pollution Specialist (APS) in the Mobile Source Analysis Branch (MSAB) of the Air Quality Planning and Science Division (AQPSD). This section is responsible for the development and refinement of the EMFAC on-road emissions inventory model. The EMFAC model supports air quality planning, transportation planning, photochemical modeling, and project level assessment. This section also plays a key role in development of on-road heavy-duty mobile source regulations by providing technical support to regulatory divisions within CARB.

Under direction of the Section Manager, the incumbent will serve as the lead for supporting on-road emissions inventory work in EMFAC for the new national ambient air quality standard (NAAQS) for particulate matter (PM). The APS will update on-road mobile source emission inventory data, including emission factors and vehicle population and activity through targeted data collection, for exhaust and non-exhaust primary PM2.5 and precursor pollutants. The APS will estimate emission reductions from the State’s mobile strategy for the new PM2.5 nonattainment areas, along with documenting the SIP assessment assumptions, methodology, and results.

In addition to technical data analysis and model development, staff are routinely asked to review the work of others, and to communicate with a wide variety of internal and external clients. We expect applicants to have an ability to communicate effectively on a technical and policy level, both verbally and in writing, with a wide variety of stakeholders including other CARB divisions, government agencies, policymakers, industry, environmental organizations, and the public.
