When EPA establishes a new national ambient air quality standard (NAAQS) or revises an existing NAAQS, it sets in motion two major actions aimed at ensuring that air quality throughout the country meets those standards:
1) EPA must designate areas as meeting (attainment) or not meeting (nonattainment) the standard; and
2) The Clean Air Act (CAA) requires states to develop State Implementation Plans (SIPs): a general plan to attain and maintain the NAAQS in all areas of the country, and a specific plan to attain the standards for each area designated nonattainment for a NAAQS.
LRAPA is responsible for crafting SIPs to meet and maintain NAAQS in Lane County. Below are the following plans for our area.
