To the EPA, “safe” is a constantly moving target—and that’s the way it likes it. Always something new to regulate, always a new hobgoblin from which to save us. Take the agency’s proposal to yet again lower allowable ozone levels. It’s another one of those win-win regulations for which the EPA is famous, supposedly saving both lives and money. But its assertions collapse when you examine the science on which they’re allegedly based.
U.S. ground-level ozone concentrations have fallen by 25% since 1980 and 14% just since 1990. Yet in 1997 the EPA tightened the screws with what it called a “safe” standard at 80 parts per billion (ppb). Then in 2008 “safe” became 75 ppb. Now the agency insists “safe” is a maximum of between 60 ppb and 70 ppb. No doubt the agency is already laying the groundwork to drop the “safe” level yet again.
Read about the EPA’s mighty effort to take us to pollution levels so low that giant national parks will nonetheless be above the allowable limit, in my article “The Hole in the EPA’s Ozone Claims” in Forbes Online.
