   *Longitude: -94.570556°
EPA Site No.: 29-095-0034

The department established the air monitoring station on Troost Avenue
primarily to track the impact of a significant pollutant source in Kansas City.

Sulfur Dioxide (SO2) Monitoring Data*

In June 2010, EPA established a new one-hour SO2 standard
of 75 parts per billion and introduced a new form for determining compliance
with the standard. The new form to determine design value requires
three years of data — the average SO2 from each hour of the year.
The department and EPA calculate the design value, using the 99th percentile
of one-hour daily maximum concentrations, averaged over three years.

Nitrogen Dioxide (NO2) Monitoring Data*

In 2010, EPA established a new one-hour NO2 standard
of 100 parts per billion. An area is in compliance if the design value is at or below the standard.
The form to determine design value requires three years of data —
the average NO2 concentrations from each hour. The department and EPA calculate
the design value, using the 98th percentile of one-hour daily maximum concentrations,
averaged over three years.

Particulate Matter (PM10) Data*

The EPA set a standard for PM10 at 150 micrograms per cubic meter of ambient air, averaged
over a 24-hour day. A site does not meet this standard if it exceeds the concentration more than once per year,
averaged over a three-year period. The department and EPA express the PM10 design value as
"expected number of days exceeding the standard." The word expected indicates that PM10
is not always measured every day.

Fine Particulate Matter (PM2.5) Data*

EPA uses two ways to determine compliance with PM2.5 federal standards. One looks at data
over a 24-hour period, and the other takes into account data from a whole year.

In 2012, EPA made the annual PM2.5 standard more stringent, setting it at 12 micrograms per cubic meter,
based on the three-year average of annual means. At that same time, EPA retained the
24-hour PM2.5 standard of 35 micrograms per cubic meter, based on the 98th percentile
of 24-hour measurements, averaged over three years.
