General Glossary

The relative amount of this pollutant emitted from this facility
during this reporting year, expressed as a percentage of the
total amount emitted in Minnesota during this reporting year.

"Secondary ambient air quality standards" or "secondary
standards" mean levels established to protect the public welfare
from any known or anticipated adverse effects, such as injury to
agricultural crops and livestock, damage to or deterioration of
property, annoyance and nuisance of persons, or hazards to air
and ground transportation. (From MN Rule 7009.0010)

"Primary ambient air quality standards" or "primary standards"
mean levels established to protect the public health from adverse
effects. The adverse effects that the standards should protect
against include acute or chronic subjective symptoms and
physiological changes that are likely to interfere with normal
activity in healthy or sensitive individuals or to interfere
unreasonably with the enjoyment of life or property. (From MN
Rule 7009.0010)

A U.S. Geological Survey (USGS) topographic map use contours to
show shape and elevation of terrain. These maps divide the
United States into quadrangles bounded by two lines of latitude
and two lines of longitude. Individual topographic maps are
commonly referred to as quadrangles or quads. The smallest
topographic quadrangle commonly published by the USGS are 7.5
minute quadrangles, which measure 7.5 minutes of latitude and
longitude.

The number of observations (N) represents the individual sample
dates used to calculate the summer-mean.

The standard error of the mean (SE) is calculated as the
standard deviation divided by the square root of the number of
observations.

Rod-shaped bacteria usually found in the intestinal tracts of
animals, including humans. Their presence in water indicates
recent contamination by human or animal feces.

These bacteria are obviously not harmful to animals or humans,
but they do indicate that sewage contamination has occurred and
suggests the presence of disease-causing bacteria and viruses
such as E. Coli, salmonella, and cryptosporidium.

Bacteria are a group of microscopic, single-celled organisms.
They may have spherical, rodlike, or spiral shapes. They
inhabit virtually all environments, including soil, water,
organic matter, and the bodies of multicellular animals.

Institutional controls are defined by Minnesota Statute,
Section § 115B.02, subdivision 9a, as legally enforceable
restrictions, conditions, or controls on the use of real
property, ground water, or surface water located at or adjacent
to a facility where response actions are taken that are
reasonably required to assure that the response actions are
protective of public health or welfare or the environment.

result from continuous exposure to an agent at a concentration
of 1 ìg/m3 in air.
