California On-Road In-Use Regulations

2

The new requirements from the California Air Resources Board (CARB) are intended to improve air quality by reducing particulate matter (PM) and oxides of nitrogen (NOx) emissions from older vehicles, by replacing older engines and upgrading to a 2010 engine or newer– Phase-in most PM requirements from 2011-2014– Phase-in NOx requirements from 2013-2023

Three options for compliance

1. Install PM retrofits and replace vehicles according to schedule based on existing engine model year

2. Retrofit a minimum number of engines each year with a high level PM exhaust retrofit and replace a minimum number of older engines with newer engines meeting 2010 new engine standards

3. Meet a fleet average; fleet operator can use PM and NOx emission factors established by regulation to calculate average emissions of the fleet
