•GIVEN that EPA concluded a 10-year review of its Air Quality Criteria for CO in
2000, including a
review of recent CO literature
showing many adverse affects at levels below the current outdoor limit of 9ppm, especially among asthmatics...
•WHY did EPA not propose lowering either its 8 hour average limit of 9ppm or its
average limit of 35ppm?
•Why does EPA still not post or publish any info about the role of CO in asthma ?
