Pursuant to Section 812 of the 1990 Clean Air Act Amendments (CAAA), EPA conducts periodic studies to assess benefits and costs of the EPA's regulatory actions under the Clean Air Act. EPA's Office of Air and Radiation (OAR) is now nearing completion of the analytical work for a second prospective study. OAR has requested advice and review of technical documents pertaining to modeling of air quality for seven emissions scenarios to be used in the study: a 1990 baseline simulation; and simulations for 2000, 2010 and 2020 with and without the Clean Air Act Amendments of 1990's. OAR is requesting the Council's Air Quality Modeling Subcommittee review the data choices, methodological choices for analyzing the data, and the overall validity and utility of the estimated changes in air quality conditions between the with-CAAA90 and without-CAAA90 scenarios.
