Description : This Request for Proposal (RFP) is to solicit competitive proposals from experienced and qualified contractors to characterize brake wear particulate matter (PM) and gaseous emissions from off-road vehicles. The characterization will include emission factors (EF) dependent on engine operation conditions (e.g., revolutions per minute and torque) for off-road vocational vehicles and their chemical speciation characteristics. Emission measurement should be conducted in standardized laboratory test conditions that are repeatable for tests and reproducible for measurement results. The results of this study will inform the off-road emission inventory, air quality planning, and off-road emission reduction programs.The Contractor shall develop brake-duty cycles for representative off-road vehicles in California, such as bulldozers, graders, loaders, dump trucks, harvesters, agricultural tractors, etc. In the development of the duty cycles, factors potentially correlated with brake wear emissions shall be accounted for, such as vocation type, vehicle weights, braking duration and events, brake system technologies, friction materials, etc. Real-time monitoring of PM2.5 and PM10 mass, total hydrocarbons, nitrogen oxides (NOx), and relevant gaseous pollutant compounds during testing cycles will be conducted. PM filter samples for both gravimetric and a suite of chemical speciation and oxidative stress analyses shall be collected. Gaseous samples shall be collected for analy...
