    If you’re wondering whether to trust the Environmental Protection Agency on mercury, ozone, climate change, or other regulatory actions, you need look no further than how it has handled particulates. EPA whitewashed the toxic flashflood it caused in Colorado. But it says particulate matter smaller than 10 microns (PM10) is risky and worries incessantly about […]

    The EPA’s justification for PM2.5 regulation is sketchy at best, given that the secret Harvard study upon which the rules are based found a statistical relative risk that is well below the legal threshold for identifying a significant potential risk. Moreover, notes CFACT contributor Dr. Charles Battig, while the EPA claims instant PM2.5 mortality begins at just 35 microns per cubic meter, a single draw on a cigarette releases up to 40,000 microns per cubic meter into a smoker’s lungs, and airport smoker lounges have ambient levels up to 10,000 microns per cubic meter. Dr. Battig concludese that the EPA has fabricated a PM2.5 disease entity, endowed it with a unique pathological profile, funded friendly “studies” that support its claims and ignored all contrary findings, and published regulations that will enhance its power and authority over the regulated community while greatly increasing the costs of doing business.
