EPA administrator Lisa Jackson affirmed this week that the EPA could view Mother Nature as a polluter.
Last week we spotlighted commentary in the New England Journal of Medicine by the chairman of the EPA’s Clean Air Scientific Advisory Council (CASAC) asserting that there is no evidence of a safe level of exposure to ozone and fine particulate matter.
This week in an allegedly-spontaneous-but-really-scripted scripted exchange of letters between Sen. Tom Carper (D-Del.) and Jackson offers asserts that the current ozone standard (75 ppb) was illegally set by the Bush administration because it fell outside the range of standards recommended by CASAC (i.e, 60-70 ppb).
So under Jackson’s view of the law, the recommendations of CASAC (which is just supposed to be an advisory body) are binding. And of course, the chairman of CASAC says there is no threshold of safety.
So as far as Lisa Jackson is concerned, the EPA could set an ozone standard at zero ppb — regardless of the fact that some ozone is naturally occurring at as much as 50 ppb.
