Time To Breathe Easy: At a meeting in Spartanburg on June 24, the South Carolina Department of Health and Environmental Control made an announcement that took many people by surprise. According to an air quality model that DHEC has just completed, changes already underway at the federal level – cleaner-burning fuels, stricter emissions standards, and the like – will be sufficient to bring the Upstate into compliance with the ozone standard by 2007. This is good news, for air quality in the Upstate has been on a downward trend for several decades.
But the danger is that some may see the results of DHEC’s model as making it unnecessary to pursue the local air quality strategies and measures recommended by the regional committee (see “Clean Air Strategies,” on page 12) – that now we can all relax and get back to business as usual. Such a response not only would be unfortunate, it also would violate the EAC. Under the EAC, the three counties must have “specific, quantified, and permanent” local measures in place as soon as practicable but not later than December 31, 2005. There is no exemption from this requirement based on what a model predicts.
There is good reason why no such exemption appears in the agreement. A model is just that – a hypothetical and approximate representation of reality, not reality itself. According to David Farren, a Clean Air Act expert who works for the Southern Environmental Law Center, this is the case with the model in question. “The history of the Clean Air Act has been one of widespread failure to meet modeled goals,” Farren explained. “The models are consistently overly optimistic, and are constantly being changed.” For example, the model for Atlanta underestimated actual emissions by 30% to 40%! Even if the model is correct, it shows that the Upstate will barely comply with the ozone standard. We must move ahead with adoption and implementation of the local air quality measures – not only because we are legally required to do so, but because it is the right thing to do. Without question the most important measures relate to the primary source of nitrogen oxides: vehicle emissions. In South Carolina during the last 15 years, the amount of driving – referred to by experts as “Vehicle Miles Traveled” (VMTs) – has increased by 45 per cent, which is three times the rate of population growth. We must directly and aggressively address the “VMT problem” through tough and effective land use and transportation policies. Clean air depends on it.
