Applying those rules to CO2 will mean imposing costly regulations not just on cars and factories but on commercial buildings, churches, and even residences. All told, more than 1 million entities could become subject to new federal controls on greenhouse emissions. [...]
The EPA is well aware of the potential regulatory nightmare—and political backlash—that enforcement of Section 165 could create, so the agency has offered to modify its carbon rules. In September, shortly after proposing the new regulations for cars and trucks, the EPA proposed a dramatically higher new threshold of 25,000 tons per year before the new greenhouse gas requirements are imposed, even though the statute expressly sets a limit of 250. The EPA estimates that the new threshold, if adopted, would force fewer than 15,000 facilities to obtain carbon permits, and most of those are already subject to other environmental regulations.
