Introduction
This report provides a map depiction of areas (by city) in
Region 10 with respect to attainment/nonattainment of air quality
standards based on air monitoring data. This report should not
be used as substitute, but as a supplement to the official
nonattainment area maps. The results of this analysis could be
used to assess the current status of air pollution
attainment/nonattainment designations in Region 10.
All monitor sites stored in the Aerometric Information
Retrieval System (AIRS) were used in this analysis. Exceptional
event data were also included in this report. Exceptional events
are events which do not occur regularly and which can cause high
pollutant concentrations (e.g. volcanoes, fires etc. ). In
Region 10 many of the exceptional events flagged in the AIRS
system are under review and the flags may be removed.
Exceptional event data are used in mitigation strategies for
cleaning up air quality problems, but they are treated separately
from other data. This report does not treat exceptional events
separately, but it includes all data points.
This analysis includes the criteria pollutants which are
regulated through the Clean Air Act (CAA). Maps for nitrogen
dioxide (NO2) are not included because there are few sites and
there are no known or suspected NO2 problems in Region 10.
A more detailed analysis will also be produced which shows
separate graphic displays for each monitor. Copies of this
report will be available on request.
