Last week, the U.S. Environmental Protection Agency announced a proposal to establish a new dust standard and provide a national exemption for farming and mining in rural areas. This means that the agency would stop monitoring for larger particle pollution in rural areas.
However, the proposed rule change would tighten rules on coarse particulates in urban areas. EPA will still monitor fine particulate matter in all areas.
The proposed changes are controversial, to say the least, especially in California. Air board officials have been vocal in their displeasure with the proposal, as well as their concerns that the regulation changes would hamper state air quality efforts.
