OSTI ID:698030
This report provides an assessment of highway particulate impacts. It evaluates the existing state of knowledge related to: (1) what the sources of the particulates are, especially those specific to highways; (2) methods of assessing particulate impacts from highway sources; (3) relationship between highway derived particulates and other particulate sources; (4) particulate instrumentation, measurement, and monitoring methods; (5) assessment potential public health risks; and (6) control strategies for mitigating highway particulate impacts. Sources evaluated included diesel and spark ignition engine emissions, tire and brake wear, resuspensions from road sanding and salting operations, and unpaved roads. Model evaluated included dispersion, source/receptor, and emissions modeling. Based on this information, four sources of highway particulates were determined to need additional study in order to more completely understand the highway particulate source problem. These area were: paved road resuspension, dust suspension resulting from road sanding and salting operations, diesel engine emissions, and unpaved roads. Although unpaved roads were considered outside of the scope of the work of this contract, the other three areas were targeted for additional field work as part of Phase 1.
