The air monitoring station at Hillcrest High School helps the
Missouri Department of Natural Resources determine exposure
to air pollutants of a segment of the Springfield population.
Specifically, it meets the federal requirement to monitor exposure
to ozone of a population of the Springfield metropolitan statistical
area (MSA). The Hillcrest High School station began monitoring
PM10 and PM2.5 concentrations, too, in April 2015
when the department relocated monitors at the Missouri
State University (MSU) station to Hillcrest High School
because of construction at the MSU site.

 

 

 

 

 

 

 

 

 

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 December 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.

The EPA has set a standard for PM10 at 150 micrograms per cubic meter of ambient air (150 µg/m3 ), averaged over a 24-hour day. A site does not meet this standard if it exceeds the level more than once per year, averaged over a three-year period. The PM10 standard is expressed as “expected number of days exceeding the standard.” The word expected is used because PM10 is not always measured every day.
