"U.S. EPA [Thursday] issued its final 'tailoring' rule for greenhouse gas emissions, a contentious policy aimed at shielding small polluters from rigid Clean Air Act permitting requirements.
EPA's rule 'tailors' permitting programs to limit the number of facilities that would be required to obtain New Source Review and Title V operating permits based on their greenhouse gas emissions. EPA said the threshold would cover power plants, refineries and other large industrial plants while exempting smaller sources like farms, restaurants, schools and other facilities.
Beginning next January, facilities that must already obtain New Source Review permits for other pollutants will be required to include greenhouse gases in their permits if they increase their emissions of the gases by at least 75,000 tons of carbon dioxide equivalent per year.
On July 1, 2011, EPA will extend the requirements to new construction projects that emit at least 100,000 tons of greenhouse gases and existing facilities that increase their emissions by at least 75,000 tons per year, even if they do not exceed thresholds for other pollutants."
