Current through Register Vol. 47, No. 3, July 24, 2024
Applicants shall submit supporting information which is
					 reasonably required to assist the department in conducting the investigation of
					 an application required by Iowa Code sections
					 455B264.
					 and
					 455B281.
					 and in determining whether granting of a permit would be consistent with the
					 policies and principles of beneficial use set forth in Iowa Code section
					 455B262..
					 Certain supporting information requirements are described in this rule. This
					 description is intended to identify frequently required information. The
					 department may require additional information relative to the permit
					 application.
(1)
Application
				  for permit to withdraw groundwater.
a.
Identification of source and
				  effects of pumping.
An applicant shall be required to submit
				  information needed by the department to identify the aquifer(s) from which
				  withdrawals of water are proposed, predict the effects of pumping with a
				  reasonable degree of confidence, and determine any permit conditions for well
				  interference pursuant to 567-Chapter 54. At many locations the only reliable
				  methods to determine the availability of a water source of adequate quantity
				  and quality and to predict the effects of pumping require test drilling, yield
				  test pumping, and a controlled aquifer test with measurements in one or more
				  observation wells conducted with prior approval in a manner that is acceptable
				  to the department. The applicant shall be required to perform each of these
				  exploratory operations to the extent necessary for the department to obtain
				  information from which to determine whether a permit should be granted and to
				  identify conditions which should be imposed in any permit granted. The
				  following requirements apply to exploratory drilling and test pumping.
(1) Test drilling. In cases where test
				  drilling is needed for geological information relevant to the application, the
				  applicant is responsible for employing a driller who will collect, bag and
				  properly label cutting samples at each five-foot interval and at each apparent
				  change in geological formation from a test hole or production well hole at
				  least the approximate depth of the proposed production well. The cutting
				  samples must be saved for collection in sample bags provided by the Iowa
				  geological survey (IGS). The samples shall be submitted to IGS and be
				  accompanied by a driller's log showing the location and total depth of the hole
				  and a description of the materials encountered at successive
				  intervals.
(2) Yield testing. An
				  applicant shall be required to construct a well and test pump it for yield to
				  the extent necessary to determine whether water is available at the applicant's
				  proposed rate of withdrawal from the proposed source. A written registration
				  from the department is required before any yield test in which more than 25,000
				  gallons will be withdrawn in a period of 24 hours or less (see 567-subrule
				  51.6(5)).
(3) Controlled aquifer
				  test with supervision. An applicant shall be required to conduct a controlled
				  aquifer test with supervision by a certified well contractor, licensed
				  professional engineer or other designee of the department as a condition of
				  obtaining a water permit if the department finds an aquifer test necessary to
				  determine the effects which the proposed withdrawal has on other water uses.
				  The applicant may be required to construct, develop, and maintain adequate
				  observation wells for use in an aquifer test and for subsequent water level
				  measurements or water quality monitoring. An applicant shall be responsible for
				  obtaining a registration for an aquifer test as provided in 567-subrule
				  51.6(5).
