According to the Mid-Hudson News, Sullivan County does not have equipment for monitoring either ozone or particulates in the air. And it's not alone:
In the Hudson Valley, most counties have ozone monitoring devices, but only Orange and Westchester have particle monitoring equipment.
Fortunately, it's not like leafy Sullivan County, and the Catskills region in general, are facing a massive industrialization of the rural landscape that could have tremendous impacts on air quality. (Oh. Right.)
Science 101: In order to measure the effects of an independent variable on a dependent variable, like gas drilling on air quality, you have to get baseline data. Without monitoring now, Sullivan County will have no way to measure the impact of drilling if and when it comes.
