Abstract:Gaseous and particle emissions from construction engines are an important fraction of the total air
pollutants and are gaining increasing regulatory attention. Quantification of NOx and PM is necessary to
inventory the contribution of the construction equipment, such as used by Caltrans, to atmospheric
loadings, particularly for those projects in non-attainment or maintenance areas. At present, however, there
is no model mutually accepted by Caltrans and regulatory agencies that can be used for the estimation of
construction emissions or the development of appropriate regulations. This is due in part to a lack of
emissions data from construction equipment under in-use operating conditions. The lack of a sound
scientific basis for regulation has resulted in legal cases and other obstacles that could potentially delay or
inhibit important transportation projects.
