EPA to start regulating GHG

So I finally finished my article about the Environmental Protection Agency's (EPA) plan to regulate under the Clean Air Act (CAA) greenhouse gas emissions from stationary sources. This is very timely given that agency published its final rule yesterday (and my deadline is this week).

Here's a little bit of a snapshot of the GHG rule. EPA's GHG pollutants by the way include carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons and sulfur hexafluoride. This is compared to the usual CAA pollutants such as lead, sulfur dioxide and nitrogen dioxide. The CAA’s current default emissions thresholds for these pollutants are 100 and 200 tons/year (tpy).
