The implementation of episodic emission control programs is becoming increasingly popular across the country as an innovative approach to reduce emissions of ozone precursors, carbon monoxide, and particulate matter. Motivation for implementation of this type of gram often stems from local government and business concerns about the attainment status of the area and the restrictions, additional controls, and costs associated with reclassification. many areas are also motivated by public health concerns and believe that increasing the amount of air quality information available to sensitive populations raises awareness and results in significant health benefits. Specific goals which are usually associated with episodic control programs include: (1) Educate the public; (2) Attain air quality standards (NAAQS); (3) Meet specific emissions reduction targets; (4) Manage/reduce congestion; (5) Maintain economic benefits associated with attainment status; (6) Protect public health; and (7) Maintain air quality standards. Episodic emission control programs, which are being implemented in 40 U.S. cities, are usually voluntary and generally provide multiple steps that the public (and/or industry) can take to reduce emissions after certain meteorological conditions are forecast to occur. The programs emphasize educating the public about the impact of individual activities on local air quality and the basics of air pollution (e.g., good ozone v. bad). The education programs are aimed at informing the public of activities to reduce pollution on both an intermittent 'episodic' basis (e.g., reduction of trips, postponement of certain activities) and on a longer term basis (maintenance of cars). |
