Notes: CAAA90 cap refers to the 8.95 million ton SO2 cap established in Title IV of the Clean Air Act Amendments of 1990. CAAA90 standards refer to the boiler emission standards for NOx established in Title V of the Clean Air Act Amendments of 1990. NOx SIP Call refers to the 19-State summer season cap on NOx emissions to begin in 2004. The time period for reaching the CO2 target of 7 percent below 1990 levels is between 2008 and 2012. The cap is then held constant at that level through 2020. The emission caps are phased in gradually until the target cap is met on the specified date. Source: See requesting letters in Appendix J. |
