On July 26, 2007, the California Air Resources Board (CARB) adopted regulations requiring the
reduction of oxides of nitrogen (NOx) and particulate matter (PM) emissions from off-road
equipment. These regulations are expected to reduce emissions of air pollutants from diesel
engines by 74% for particulate matter and 32% for oxides of nitrogen by 2020.
Who is affected?
Anyone who owns or operates diesel-powered off-road vehicles with engines
over 25 horsepower. Exemptions: equipment operated for agricultural purposes
or at ports or intermodal rail yards
When are the compliance deadlines?
The year in which compliance must begin is determined by the size of the fleet.
What category does your fleet fall in? Combine the total horsepower for all
equipment in your fleet and consult the chart below:
| Combined Horsepower |
Size of Fleet |
Begin Compliance |
| <2500 | Small | 2015 |
| 2501 – 5000 | Medium | 2013 |
| >5000 | Large | 2010 |
What are the emissions requirements?
All three fleet size categories must meet the emission rate targets for PM:
- Each fleet must meet a specified average emission rate target, which is
an average for the entire fleet, OR
- Apply the highest level of verified diesel emission control system to 20%
of the fleet’s horsepower by applying exhaust retrofits or by trading older
machines for newer, cleaner engines.
Medium and large fleets must meet the emission rate targets for NOx:
- Each fleet must meet a specified average emission rate target, which is
an average for the entire fleet; OR
- Turn over a specified percentage of their horsepower every year (8% in
early years, 10% in later years). Turnover options include: repower with a
cleaner engine, retire a vehicle, replace a vehicle with a new or used
machine, or designate a dirty vehicle as low-use. If retrofits become
available that reduce NOx, they may be used for turnover, as long as the
emission benefits are met.
*Fleets located in rural and attainment areas are only required to lower PM.
What is the estimated industry cost?
The total cumulative cost of the regulation is estimated to be between $3.0
and $3.4 billion in 2006 dollars. The majority of these costs would occur
between 2010 and 2021. This cost represents less than 0.3% of the total
construction revenue for California in 2005.
