Section 347.03. Definitions.

 

(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.
