The analysis also showed that many volunteering companies had promised to make no reductions or had made promises of only distant or indefinite reductions. The failure to have a valid plan on file makes it impossible to do the required conformity with the plan analysis required by law to continue to receive federal highway dollars. Because of its past failures to meet federal health standards, the State is required to file new plans to clean the air. Our campaign is aimed, in part, at trying to influence these plans to actually reduce pollution significantly, as opposed to simply meeting minimum administrative requirements. Los Angeles like El Paso is also a nonattainment area for particulates.
Weather does play a part in smog formation.
It is not clear that if the entire summer is looked at that this summer was an unusually hot and still. To account for weather variations of any one-year, our analysis looked at three and five year periods. Multi-year analysis shows that the air is getting dirtier in general, except for El Paso. Since 1995 a number of high growth areas like Charlotte, N.C., Nashville, and Salt Lake City have made sufficient progress to come out of nonattainment.
