a. In accordance with these rules and with
			 the conditions of approval of any drilling permit issued pursuant Section
			 42-235, Idaho Code, and in a
			 manner that will prevent waste and contamination of the ground water resources
			 of the state of Idaho. The adopted standards are minimum standards which must
			 be adhered to in the construction of all new wells, and in the modification or
			 decommissioning (abandonment) of existing wells. The well driller is charged
			 with the responsibility of preventing waste or contamination of the ground
			 water resources during the construction, modification or abandonment of a well.
			 The Director may add conditions of approval to a drilling permit issued
			 pursuant to Rule 45 of these
			 rules to require that a well be constructed, modified, or decommissioned
			 (abandoned) in accordance with additional standards when necessary to protect
			 ground water resources and the public health and safety from existing
			 contamination and waste or contamination during the construction, modification
			 or decommissioning (abandonment) of a well. (3-18-22)
b. In consideration of the geologic and
			 ground water conditions known to exist or anticipated at the well site.
			 (3-18-22)
c. Such that it is
			 capable of producing, where obtainable, the quantity of water to support the
			 allowed or approved beneficial use of the well, subject to law;
			 (3-18-22)
