These State Implementation Plans (SIPs) are the roadmaps to meeting the 1997 8-hour ozone National Ambient Air Quality Standards (NAAQS) of 0.08 In 1997, EPA first established the 8-hour ozone standard, which replaced the older 1-hour ozone standard (0.12 Source: EPA.

the criteria pollutants and CO 2 that emerge with the exhaust from the tailpipe. However, there is more than 15 years of research showing that the contribution of non-exhaust primary particles to the total traffic generated primary particles is significant in urban areas.

Compared to the 2010 “Business as Usual” scenario—which includes all adopted emission control measures for the South Coast—NO x levels must be reduced by 65% and by 75% to meet the 2023 and 2032 ozone standards, respectively. An 80% reduction of GHG emissions is targeted for 2050, relative to 1990 levels.

Testing is due to be complete next year, prompting the auto, oil and outdoor power equipment industries to urge the Environmental Protection Agency (EPA) to delay action on its proposal to allow higher levels of ethanol in gasoline until that testing is done.

(The figure includes the direct effects and those indirect effects due to the production of tropospheric ozone and stratospheric water vapor.) Overall, EPA reported a slightly less than 1% drop in methane (CH 4 ) emissions from 2010 to 2011 (from 592.7 12.6%) decrease under 2010 emission levels. CH 4 emissions represented 8.8%
