Introduction
The Lane Regional Air Pollution Authority conducted a PM10 saturation monitoring study in Oakridge, Oregon, during February, 1991. That 1991 study concluded that the west end of the Oakridge area was subject to episodes of PM10 concentrations even higher than that being measured at the permanent monitoring station located at the edge of the Willamette Activity Center ball field ("WAC", ODEQ ID: 2030003, AIRS ID: 410392013). The study concludes that "because high PM10 levels were also recorded at Saint Luke's Church and Cline Street, it may be valuable to additionally monitor air quality at one of these locations... Saint Luke' Church is preferable as it is farther from the present monitoring site. In addition it has the highest mean PM10 concentration of all sites in the study and the highest design value calculated from the Tail Exponential Distribution."
