If you're driving southbound 75 and happen to notice a shelter with a large antenna-like device sticking out the top near the 74 interchange, don't worry. It's not spying on you or engaging in personal data mining. It's among the first in a new national air monitoring program that starts this month.
The Southwest Ohio Air Quality Agency started the new program to monitor for air pollution in near-road environments. And you can't get much nearer than this site, which sits about 15 to 20 feet from the interstate.
