Current through June 24, 2024
(1) "Analyte" means the chemical substance or
				physical property being tested for in a sample.
(2) "Bathymetry" means the measurement of
				depth of water in lakes or rivers to determine lake or river bed
				topography.
(3) "Beach nourishment
				disposal" means the disposal of dredged material on the beaches or in the water
				landward from the ordinary high-water mark of Lakes Michigan and Superior for
				the purpose of adding, replenishing or preventing erosion of beach
				material.
(4) "Bioassay" means a
				method for determining the acute or chronic toxicity of a material by studying
				its effects on test organisms under controlled conditions.
(5) "Bulk sediment analysis" means a test to
				measure the total concentration of a specific constituent in a sample being
				analyzed.
(6) "Carriage water"
				means the water portion of a slurry of water and dredged material.
(7) "Carriage water return flow" means the
				carriage water which is returned to a receiving water after separation of the
				dredged material from the carriage water in a disposal, rehandling or treatment
				facility.
(8) "Connecting
				waterways" means a portion of a navigable lake or stream which is directly
				joined to Lake Michigan or Lake Superior and which contains a navigation
				channel providing access for commercial or recreational watercraft to Lake
				Michigan or Lake Superior.
(9)
				"Contamination" means a solid, liquid or gaseous material, microorganism,
				noise, heat, odor, or radiation, alone or in any combination, that may harm the
				quality of the environment in any way.
(10) "Contract" means a binding written
				agreement between the department and a dredging applicant authorizing the
				removal of material from the bed of a natural navigable lake or outlying
				water.
(11) "Department" means the
				department of natural resources
(12) "Disposal facility" means a site or
				facility for the disposal of dredged material.
(13) "Dredged material" means any material
				removed from the bed of any waterway by dredging.
(14) "Dredging" means any part of the process
				of the removal of material from the beds of waterways; transport of the
				material to a disposal, rehandling or treatment facility; treatment of the
				material; discharge of carriage or interstitial water; and disposal of the
				material.
(15) "Grain size
				analysis" means a method to determine dredged material and disposal site
				sediment particle size distribution.
(16) "Hazardous waste", as defined in s.
				291.01(7),
				Stats., means any solid waste identified as a hazardous waste under ch. NR
				661.
(17) "Interstitial water"
				means water contained in the interstices or voids of soil or rock in the
				dredged material.
(18) "Limit of
				detection" means the lowest concentration level that can be determined to be
				statistically different from a blank sample for that analytical test method and
				sample matrix.
(19) "Limit of
				quantitation" (LOQ) means the concentration of an analyte at which one can
				state with a stated degree of confidence for that analytical test method and
				sample matrix that an analyte is present at a specific concentration in the
				sample tested.
(20) "Parent
				material" means the native unconsolidated material which overlies the
				bedrock.
(21) "PCBs" means those
				materials defined in s.
				299.45(1)
				(a), Stats.
(22) "Particle size distribution" means a
				cumulative frequency distribution or frequency distribution of percentages of
				particles of specified diameters in a sample.
(23) "Rehandling facility" means a temporary
				storage site or facility used during the transportation of dredged material to
				a treatment or disposal facility.
(24) "Treatment facility" in this chapter
				means a natural or artificial confinement facility used for the separation of
				dredged material solids from the interstitial or carriage water.
(25) "Upland disposal" means the disposal of
				dredged materials landward from the ordinary high-water mark of a waterway or
				waterbody.
