Federal regulations which identify Army Corps of Engineers
(ACOE) general policies to implement Section
404 of the Clean Water Act. Part 320 outlines the ACOE's
general policies; Part 321 -- permit regulations for dams and dikes; Part
322 -- permit regulations for structures; Part 323 -- permit regulations
for dredged materials; Part 324 -- permit regulations for ocean dumping;
Part 325 -- permit regulations for discharges
to navigable waters and wetlands; Part 326 --
enforcement policies; Part 327 -- public hearings; Part 328 -- definition
on navigable waters regulations; and Part 330 -- nationwide
permit program regulations.
Federal regulations for air, waste, and water-related programs.
Water-related regulations include the National Pollutant Discharge
Elimination System (NPDES), water quality standards,
discharges to navigable waters, other discharges, and
test procedures. See also Code of Federal Regulations.
A reduction in the degree or amount
The build-up of a substance
in a plant or animal due to repeated exposure to and uptake of that substance
from the environment. See also bioaccumulation.
The total amount of pollutants
that make up what is commonly referred to as acid rain. This
includes both the wet deposition and dry deposition
components that settle out of the atmosphere. See acid rain.
Occurs when sulfur
dioxide and nitrogen oxide emissions are transformed
in the atmosphere and return to the earth in rain, fog or snow. Acid rain can
damage lakes, harm forests and buildings, contribute to reduced visibility, and
may damage human health. Regulations have been implemented
at the federal and state (MN) level to reduce acid rain. Related Programs - Clean

comparative study in which organisms, are subjected to different treatments, are
observed for a short period usually not constituting a substantial portion of
the organism's life span.
effects to a plant or animal that result from an acute exposure to a stimulant
such as a pollutant. The exposure usually does not constitute a substantial portion
of the life span of the organism. In standard laboratory toxicity
tests with aquatic organisms, an effect observed in 96 hours or less is typically
considered acute. Also described as a stimulus severe enough to induce an effect.
A term that describes organisms or processes
that require the presence of molecular oxygen.

health and environmental hazards, such as cancer or other illnesses. Also see

Simple plants found in water
and elsewhere that have no roots, flowers or seeds. These are usually microscopic
plants and are the primary producers in lakes. See also phytoplankton
A measurement made, using a standard toxicity test, to
determine how toxic a natural water body is. In some cases a water body may already
possess some degree of toxicity before a known pollutant is discharged into it.
A term that describes processes that
occur in the absence of molecular oxygen. See also anoxia.
The absence of oxygen or a deficiency
of oxygen that is harmful to living organisms. Anoxic conditions can develop in
a lake bottom when oxygen is depleted by decomposition
processes. This often happens in eutrophic lakes and
can result in fish kills. See also anaerobic.
Anything that is human-caused or derived.
A federal policy to ensure that water bodies that
have been improved are kept at that higher quality. Point
source dischargers are required by governments to meet effluent
limits, but if discharges become cleaner, or fall
below the limit, they are not allowed to go up again. The relaxation of National
Pollutant Discharge Elimination System permit limits are not allowed, except
in certain, limited circumstances.
A federal policy to protect water quality. The policy states that the existing
high quality of a particular water resource cannot get worse unless justified
by economic and social development considerations. Contained in U.S. water
quality standards and applied in the Water Quality Guidance
for the Great Lakes System. Related Programs - Clean

Aquatic Nuisance Species
Water-borne plants or animals that pose a threat to humans,
agriculture, fisheries, and/or wildlife resources. See also,
non-indigenous species, zebra mussel, Bythotrephes,
Eurasian ruffe, Eurasian watermilfoil.
Aquatic Nuisance Species Great Lakes Panel
federal organization formed in 1991 by the Great Lakes Commission
to advance exotic species research, monitoring, and control
activities. The activities conducted are based on federal legislative and budgetary
needs and research and management requirements. Activities include Great Lakes-wide
Aquatic Nuisance Species Task Force
An international organization that develops and implements programs to prevent
the introduction and distribution of aquatic nuisance species.
Their goal is to monitor, control, and study these species, and to disseminate
technical and educational information. Made up of 19 provincial, state, and federal
Area of Concern AOC
of the Great Lakes identified by the International
Joint Commission as having serious water pollution problems requiring remedial
action and the development of a Remedial Action Plan.
AOCs are defined in the Great Lakes Water Quality Agreement
as follows: ... a geographic area that fails to meet the general or specific objectives
of the Great Lakes Water Quality Agreement, or where such failure has caused or
is likely to cause impairment of beneficial use or of
the areas ability to support aquatic life. Initially, there were 43 AOCs in the
Great Lakes Basin. The 8 AOCs in Lake
Superior are; Deer and Torch Lakes in Michigan, St. Louis River in Minnesota
and Wisconsin, Jackfish Bay, Nipigon Bay, Thunder Bay, and Peninsula Harbour in
Ontario, and St. Marys River in Michigan and Ontario. Related Programs - Great

One of several regional development commissions located throughout Minnesota,
this one serves seven counties in northeastern Minnesota. Through its mission
to provide local leadership it is involved in many issues related to the environment
