Iowa Administrative Code › Agency 567 - Environmental Protection Commission › Title V - Flood Plain Development › Chapter 73 - Approval, Construction, Use, Maintenance, Removal, Inspections, and Safety of Dams › Rule 567-73.10 - Review and Approval Process for Dam Construction, Modification, Abandonment, or Removal

Current through Register Vol. 47, No. 3, July 24, 2024
(1)
Application process.
Application materials are provided by the
				department. The application shall be submitted by or on behalf of the person or
				persons who will be the future dam owner or owners. The application shall be
				signed by the applicant or a duly authorized agent. Completed applications
				along with supporting information shall be submitted to the department through
				an online application system or mailed to Iowa Department of Natural Resources,
				Attn: Joint Application, 502 East 9th Street, Des Moines, Iowa 50319. For dam
				repairs, abandonment, or removal, the department may waive the requirements of
				the application process outlined in this rule if the requirements are
				unnecessary for the application approval or if the dam has been designated as
				unsafe and immediate temporary emergency stabilization repairs are required to
				prevent failure of the dam. Permanent repairs or modifications will require
				review and approval.
(2)
Preliminary application packet.
The preliminary application
				packet includes the joint application form and requires submittal of
				preliminary design data prepared by or under supervision of a professional
				engineer licensed in the state of Iowa or by an engineer working for the United
				States government. The preliminary design data packet shall contain a report
				summarizing the preliminary design, hydrologic data and reservoir routing, a
				hazard potential analysis, preliminary design drawings, the soils and
				geotechnical engineering analysis, and a list of the engineering references
				used as the basis for design and construction.
(3)
Project review.
The
				department shall review a preliminary application packet and provide feedback
				or concurrence on the initial design and assumptions. After concurrence with
				the preliminary application packet and upon reception of the final submittal as
				required by subrule 73.10(4), the department will review the final submittal
				and issue a decision based on whether the project meets criteria for approval
				outlined in this chapter.
(4)
Final submittal.
After the department's review of and
				concurrence with the preliminary submittal, the engineering plans and other
				engineering information shall be certified by a professional engineer licensed
				in the state of Iowa, unless prepared by an engineer working for the United
				States government, and submitted with the following information:
a. One complete set of certified construction
				plans;
b. One complete set of
				construction specifications;
c. An
				operating plan, if required;
d.
				Easements, if required;
e. For high
				hazard dams, an emergency action plan; and
f. An engineering design report documenting
				all aspects of the design of the dam and how the design of the dam meets the
				criteria outlined in this chapter. The engineering design report shall include
				the following: hazard potential analysis; hydrology and hydraulic calculations;
				embankment design and foundation analysis; and structural calculations, where
				applicable.
