What to Expect From EPA: Regulation of Greenhouse Gas Emissions Under the Clean Air Act

摘要

EPA is proceeding with regulation of both mobile and stationary sources of GHG pollution under the existing CAA. This approach will entail vehicle emissions standards for mobile sources and PSD and NSPS requirements for stationary sources. It is very unlikely that EPA will establish GHG ambient air quality standards or list GHGs as hazardous under the CAA. States will have a very significant role in regulating stationary sources, given their role as permit administrator under the PSD program and primary regulator of existing sources through the NSPS program.
