Current through June 24, 2024
(1) DEFINITIONS. In this section:
(a) "Agricultural chemigation system" means a
				  chemigation system that mixes pesticides with irrigated water and applies the
				  pesticides with the irrigation water in an agricultural setting.
(am) "Automatic low pressure drain valve"
				  means a self-activating device which is designed and constructed to drain the
				  water supply pipeline in a chemigation system if water pressure falls or the
				  water supply pump ceases operation.
(b) "Calibrate" means to measure and adjust
				  the dispersal or output of equipment to control the rate of pesticide
				  dispersal, and the droplet or particle size of pesticides dispersed by that
				  equipment.
(c) "Check valve" means
				  a device designed and constructed to close a water supply pipeline, pesticide
				  injection line, or other conduit in a chemigation system and to prevent reverse
				  flow in that line.
(d)
				  "Chemigation" means the application of pesticides using a chemigation
				  system.
(e) "Chemigation system"
				  means a device or system which mixes pesticides with irrigation water drawn
				  from any source, and which applies the pesticides with the irrigation water.
				  "Chemigation system" includes all of the components of the system. "Chemigation
				  system" does not include any of the following:
1. A hand-held or hose-end sprayer.
3. A device or system used only to inject
				  pesticides directly into plants.
4.
				  A device or system used only to apply pesticides directly to the roots of
				  ornamental trees and shrubs.
(f) "Flush time" means the time needed under
				  normal operating conditions to completely fill an irrigation system with water
				  so that all outlets are discharging water.
(g) "Injection unit" means a chemical
				  metering pump or device that withdraws pesticide from a supply tank and injects
				  the pesticide into irrigation water during chemigation.
(gm) "Non-agricultural chemigation system"
				  means a chemigation system that is used to apply pesticides in a
				  non-agricultural setting, including to urban lawns and gardens.
(h) "Pesticide supply tank" means a container
				  used to hold pesticides for injection into a chemigation system.
(j) "Potable water supply" means a well or
				  other source of water which is used for human consumption, hygiene, or
				  preparation of food products.
(k)
				  "Reduced pressure principle backflow preventer" means a backflow prevention
				  device consisting of 2 independently acting check valves, spring-loaded to a
				  closed position and separated by an intermediate chamber in which there is an
				  automatic relief that is vented to the atmosphere and spring-loaded to the open
				  position.
(km) "Urban pesticide
				  misting system" means a non-agricultural chemigation system that draws water
				  from any source, mixes the water with a pesticide, and applies the mixture
				  outdoors and into the air to kill, repel, or otherwise control pests in an
				  urban setting, including a residential or commercial area.
(L) "Vacuum relief valve" means an
				  atmospheric device designed, constructed, and installed to protect against
				  back-siphonage by allowing the entry of air to relieve vacuums in a chemigation
				  system.
