Research Projects

To add air pollutant emissions from non-automotive vehicular sources to the California Air Resources Board's (ARB's) area source data base, this program was conducted to inventory emissions from (1) construction equipment, (2) farm machinery, (3) boats, and (4) industrial vehicles. Methodologies were developed for each of the four vehicle categories to inventory the emissions from each county and air basin in the state. Using the the developed methods an inventory was performed for the South Coast Air Basin (SCAB). It was found that these emissions are significant when compared with those from stationary point sources in the SCAB.

This final report presents the considerations taken into account in developing the methodologies, presents procedural statements for conducting a statewide inventory, and summarizes the SCAB inventory results. A computer magnetic tape file of the individual area source and a computer printout of these data were also delivered to the ARB as part of this program.

The information presented in this report was compiled specifically for the State of California and may not be applicable to regions outside of this state.
