Abstract:
Tacoma-Pierce County Maintenance Area (a.k.a. Wapato Hills-Puyallup River Valley PM2.5 Nonattainment Area)
Purpose:
Air Quality monitoring/restriction area for fine particulate matter in Pierce County.
Supplemental_Information:
Most of Pierce County was designated a nonattainment area for fine particle pollution (PM2.5) in 2009 because fine particle pollution levels too frequently exceeded the national limit. Exceeding this limit can result in public health risks. In February 2016 the name changed to Tacoma PM2.5 Maintenance Area.
