Estimated nationwide VOC emissions by source category, by year. Assumes no
regulations other than those in place in 1987. The estimates are representative of the emissions
on a typical nonattainment day, multiplied by 365 days per year, rather than estimates
of true annual emissions. The baseline does not include reductions due to the limit
on gasoline volatility of 10.5 psi Reid vapor pressure (RVP). Stationary sources that emit more than
50 tons per year of VOC are included in the "Large" category. Source: OTA, 1989.
