How Absurd Is Regulating Greenhouse Gases through the Clean Air Act?
by MARLO LEWIS on SEPTEMBER 27, 2011
Pretty darn near the height of absurdity. That’s not just my opinion. It’s a key premise of EPA’s “Tailoring Rule,” which exempts small greenhouse gas (GHG) emitters from regulation under the Clean Air Act’s (CAA) Prevention of Significant Deterioration (PSD) pre-construction permitting program and Title V operating permits program.
As EPA explains in a brief filed last week with the D.C. Circuit Court of Appeals, once the agency’s GHG emission standards for new motor vehicles took effect on January 2, 2011, “major stationary sources” of GHG emissions became “automatically subject” to PSD and Title V permitting requirements. A facility with a potential to emit 250 tons per year (tpy) of a regulated air pollutant is a “major source” under PSD. A facility with a potential to emit 100 tpy is a “major source” under Title V. Whereas only large industrial facilities emit 100-250 tpy of smog- and soot-forming air pollutants, literally millions of small entities — big box stores, apartment and office buildings, hospitals, schools, large houses of worship, Dunkin’ Donut shops – use enough natural gas or oil for heating or cooking to emit 100-250 tpy of carbon dioxide (CO2).
