If a city exceeds ozone levels and ends up on the list, any contiguous county is also added. I see the need in places like Dallas, where Collin county is almost as densely populated as Dallas county, without a large population center in any one city. If San Antonio were to fail (and they have come close several times) four or five very rural counties will be added to the list along with Bexar county.
Not necessarily. I live in Marion County, Tennessee. Adjacent Hamilton County (Chattanooga) has emissions testing, as does Shelby County (Memphis) Davidson County (Nashville) and Blount County (Knoxville). If I move to any of the counties I just listed, I have to get my vehicles emissions tested each year. No emissions testing for those of us in adjacent counties. How long that will last I do not know. Chattanooga is getting more and more industries moving in, and existing industries such as Volkswagen are expanding. Emissions testing was a factor in where we choose to move to in Tennessee, the DW and I moved here from Florida nearly five years ago. Florida became too expensive for a retired Air Force NCO who has health issues and cannot work full time.
That's strange, I'm just repeating what was reported in the newspaper the last time San Antonio failed the air quality test. They were able to have several noncompliance test removed because of air pollution which was traceable to fires in Mexico. That put them under the limit. I wonder what actually governs when adjacent counties also require smog checks.
on edit: This is actually hard information to find as a search yields a whole lot of hits from states and few from the EPA. It looks like it may be determined by what cities and counties make up a metropolitan statistical area. All the references I find use the words San Antonio/New Braunfels metropolitan statistical area.
