The Panel requested that EPA prepare a fourth draft containing the results of re-analysis of the time-series studies. As a result of these delays, EPA will likely neither reaffirm the existing National Ambient Air Quality Standards for Particulate Matter or promulgate new standards before late or early Cited by: GAO reviewed the Environmental Protection Agency's (EPA) new rule on national ambient air quality standards for particulate matter. GAO found that (1) the final rule revises the primary and secondary national ambient air quality standards for particulate matter; and (2) EPA complied with applicable requirements in promulgating the rule.
Canadian Ambient Air Quality Standards (CAAQS) for fine particulate matter (PM) and Ozone have been developed through a collaborative process involving the federal, provincial and territorial governments and stakeholders, as directed by the Canadian Council of Ministers of the Environment (CCME) in October, File Size: KB. The AQI is based on the National Ambient Air Quality Standards (NAAQS) for the six criteria pollutants. The AQI is on a scale of 0 to , with corresponding to the NAAQS set by the EPA. A higher AQI value means a larger level of air pollution and a .

On Jfollowing a lengthy scientific review process, the EPA revised the national ambient air quality standards for ground-level ozone and particulate matter. Specifically, the EPA is phasing out and replacing the previous 1-hour ozone standard with a new 8-hour standard to protect against longer exposure periods.
