What are the air quality effects?
The CRC Draft Environmental Impact Statement presents an analysis of the project’s effect on concentrations of the Environmental Protection Agency’s criteria pollutants and mobile source air toxics. The analysis found that all alternatives (including no build) would result in a decline of emissions in 2030: • Carbon monoxide – 30 percent reduction • Nitrogen oxides – 70 percent reduction • Volatile organic compounds – 50 percent reduction • Particulate matter – 90 percent reduction These air quality improvements are primarily due to cleaner fuels, cleaner engines and more fuel efficient vehicles. The CRC project will incorporate many features which are likely to further reduce emissions, including congestion reduction, highway safety improvements, tolling, more transit options and pedestrian and bicycle facility improvements.
