An area with outdoor air exceeding the limit for a given pollutant is considered a non-attainment area for that pollutant. An area may be a non-attainment area for one pollutant and an "attainment area" for others. However, these pollutants are frequently associated with each other and thus a non-attainment area typically fails multiple standards.
In the United States, emissions standards are managed by the Environmental Protection Agency (EPA). It uses tiers to identify emission standards for cars, trucks and other motor vehicles. [ 8 ] In 2014, the EPA published its "Tier 3" standards for these vehicles, which tightened air pollution emission requirements and lowered the sulfur content ...
Discarded Wastes: P-List and U-List wastes are actually sublists of the same major list applying to discarded wastes.
