(3-15-22)05.Check Valve. A certified valve designed and constructed to close a water supply pipeline, chemical injection line, or other conduit in a chemigation system to prevent reverse flow in that line. (3-15-22)06.Chemigator. Any person engaged in the application of chemicals through any type of irrigation system. (3-15-22)07.Cross-Connection. Any connection that may have chemical injected or introduced into the domestic water supply system and has the potential of or is connected to the domestic water supply system. (3-15-22)08.Demonstration and Research. The use of restricted use pesticides to demonstrate the action of the pesticide or conduct research. (3-15-22)09.Domestic Water Supply System. Any system providing water for human use. (3-15-22)10.Drip Irrigation. A method of microirrigation wherein water is applied as drops or small streams through emitters. (3-15-22)11.Flood Irrigation. Method of irrigation where water is applied to the soil surface without flow controls, such as furrows, borders or corrugations. (3-15-22)12.Flow Rate. The weight or volume of flowable material per unit of time. (3-15-22)13.Furrow Irrigation. Method of surface irrigation where the water is supplied to small ditches or furrows for guiding the water across the field. (3-15-22)14.Hazard Area. Cities, towns, subdivisions, schools, hospitals, or densely populated areas. (3-15-22)15.High Volatile Esters. Formulations of 2,4-D which contain methyl, ethyl, butyl, isopropyl, octylamyl and pentyl esters. (3-15-22)16.Injection Pump. A pump that uses a gear, rotary, piston or diaphragm to develop the pressures exceeding the irrigation system pressure to inject a chemical. (3-15-22)17.Inspection Port. An orifice or other viewing device from which the low pressure drain and check valve may be observed. (3-15-22)18.Limited Supervision. Pertains to the supervision of a currently licensed pesticide applicator who holds the Commercial Apprentice (CA) category. The Supervising Applicator will be currently licensed in the same category necessary for the pesticide application, and is limited to supervising a maximum of two Commercial Apprentice applicators and must maintain immediate communications (voice, radio, cellular telephone, or similar) with the supervised applicators for the duration of all pesticide applications. (3-15-22)19.Low Volatile Esters. Formulations of 2,4-D; 2,4-DP; MCPA and MCPB which contain butoxyethanol, propylene glycol, tetrahydrofurfuryl, propylene glycol butyl ether, butoxy propyl, ethylhexyl and isoctyl esters. (3-15-22)20.Mixer-Loader. Any person who works under the supervision of a professional applicator in the mixing and loading of pesticides to prepare for, but not actually make, applications. (3-15-22)21.On-Site Supervision. Pertains to the application of Restricted Use Pesticides (RUP): On-Site Supervision of an unlicensed pesticide applicator or a pesticide applicator who does not hold an appropriate category for the RUP being applied. Supervising pesticide applicator must be physically at the site of application, must have visual contact with the pesticide applicator, and must be in a position to direct the actions of the pesticide applicator. The supervising applicator may not supervise more than two pesticide applicators. (3-15-22)22.Pesticide Drift. Movement of pesticide dust or droplets through the air at the time of application or soon after, to any site other than the area intended. (3-15-22)23.Pressure Switch. A device which will stop the chemical injection pump when the water pressure decreases to the point where chemical distribution is adversely affected. (3-15-22)24.Recertification. The requalification of a certified person through seminar attendance over a set period of time, or taking an examination at the end of a set period of time, to ensure that the person continues to meet the requirements of changing technology and maintains competence. (3-15-22)25.Reduced Pressure Principle Backflow Prevention Assembly (RP). An assembly containing two (2) independently acting approved check valves together with a hydraulically operating, mechanically independent pressure differential relief valve located between the check valves and at the same time below the first check valve. The unit shall include properly located resilient seated test cocks and tightly closing resilient seated test cocks and tightly closing resilient seated shutoff valves at each end of the assembly. (3-15-22)26.Seminar. Any Department-approved meeting or activity convened for the purpose of presenting pesticide recertification information. (3-15-22)27.Sprinkler Irrigation. Method of irrigation in which the water is sprayed, or sprinkled, through the air to the ground surface. (3-15-22)28.System Interlock. Safety equipment used to ensure that a chemical injection pump will stop if the irrigation pumping plant stops to prevent the entire chemical mixture from emptying from the supply tank into the irrigation pipeline. The safety equipment may also be used to shut down the irrigation system if the injection system fails. (3-15-22)29.Vacuum Relief Valve. A device to automatically relieve or break a vacuum. (3-15-22)30.Venturi. A differential pressure injector that operates on a pressure difference between the inlet and outlet of the injector and creates a vacuum inside the body, which results in suction through the suction port. (3-15-22)31.Venturi Injection System. A chemical injection system which operates with a Venturi using the suction from the Venturi that can be used to inject and mix chemicals into the water. (3-15-22)32.Working Pressure. The internal operating pressure of a vessel, tank or piping used to hold or transport liquid. (3-15-22)33.Waters of the State. Any surface waters such as canals, ditches, laterals, lakes, streams, or rivers. (3-15-22)Idaho Admin. Code r. 02.03.03.010
