				  160.09,
				  Stats., and ss.
				  NR
				  140.10 and 140.12.

				  116.03(16).
(14) "Floodway" means the portion of a river
				  or stream required to carry the regional flood as specified under s.
				  NR
				  116.03(22).
(15) "Food-chain crop" means a crop grown for

(18) "Hazardous wastes"
				  has the meaning specified under s.
				  NR
				  660.10(52).
(19) "Hydraulic application rate" means the
				  volume of liquid waste evenly spread over a designated acreage of the land
				  treatment system divided by a period of time as specified in the WPDES permit.
				  The rate is calculated by dividing the volume discharged during the waste
				  loading period by the acreage of land loaded and then dividing by the total
				  time in the load/rest cycle.
(20)
				  "Incinerator" has the meaning specified under s.
				  NR
				  500.03(65).
(21) "Infiltration rate" means the rate of

				  rotary tilling to a minimum depth of 4 inches.
(23) "Intensity of application" means the
				  instantaneous rate, reported as inches per hour, at which liquid waste is
				  applied to land.
(24) "Land
