Digging Into Air Pollution Problems - An Earthmover's Viewpoint 720609
This paper comments on the status of emission regulations; provides estimates of emissions from earthmoving vehicles based on Caterpillar information and compares this with diesel powered off-highway machinery based on Bureau of Mines data; suggests that simple emission test procedures may suffice for the great variety of equipment used in the construction industry if standards are established; and proposes that non-productive testing to prove conformance to standards be minimized.
