Current through Register Vol. 49, No. 14, July 15, 2024
PURPOSE: To remove out of date portions of the rule
				  and to remove right of entry language restated from statute.
(1) In addition to the basic requirements for
				all permits listed in
				10 CSR
				22-3.030, the construction permit application for a
				conventional dam and reservoir shall be prepared under the direction of and
				certified by an experienced professional engineer and shall be in accordance
				with practices reputable and appropriate in the engineering, geologic, and
				construction professions.
(A) The following
				information shall be provided by the owner:
1. Up-to-date topographic map(s) showing the
				location of the proposed or existing dam, the upstream watershed, the
				reservoir, and the downstream environment zone. An up-to-date United States
				Geological Survey topographic map is considered a minimum;
2. Exploration records and results including
				the location of all exploration, especially in the area of the core trench, the
				method(s) used to explore the site, a record of what was found, the method(s)
				used to obtain samples, and the number of samples taken;
3. Testing records and results including
				information on the care and treatment of samples, types of tests performed on
				samples or in situ, reference(s) to or the procedures used in testing, and the
				test results. Physical and mechanical properties of foundation and construction
				materials must include the information source for these values especially if
				they are not the results of testing;
4. The geotechnical design procedure(s) or
				method(s) shall be identified and referenced or described so that they may be
				reviewed and the applicability verified. This shall include all assumptions
				made. The geotechnical procedure(s) or design results shall include the minimum
				computed factors of safety and they must meet or exceed the design factors of
				safety (see 10 CSR
				22-3.020(4) ). The geotechnical
				design information shall be presented for the foundation, core trench, and dam
				embankment. Earthquake loading must be analyzed as outlined in
				10 CSR
				22-3.020(5) and (6);
5. The structural design procedure(s) or
				method(s) shall be identified and referenced or described so that they may be
				reviewed and their applicability verified. Design results for concreted dams
				and concrete structures appurtenant to embankment dams shall provide for and
				show an adequate factor of safety for normal and maximum loading conditions of
				compression, tension, shear, torsion, buckling, sliding, and
				overturning;
6. Hydrologic
				information used to evaluate the watershed, reservoir, spillway, and downstream
				environment zone including the watershed area, rainfall rate and duration,
				antecedent moisture conditions, time of concentration, area capacity curves,
				description of spillway elevation(s), type(s), dimensions, locations, cross
				section and profiles, dam crest elevation, and the downstream valley cross
				sections;
7. The
				hydrologic/hydraulic design procedure(s) or method(s) used shall be identified
				and referenced or described so that they may be reviewed and their
				applicability verified. This shall includes all assumptions made. The
				hydrologic/hydraulic procedure(s) or design results shall include the reservoir
				inflow hydrograph, the reservoir outflow hydrograph, the spillway discharge
				capacity, the freeboard at the maximum water storage elevation, and the
				environmental class of the dam. The dam shall be capable of safely containing
				or discharging the required design flood (see
				10 CSR
				22-3.020(5) );
8. Location and design of diversion channels
				or other structures to control stream flow during or after construction shall
				be provided if failure of these channels or other structures would affect
				hydrologic conditions of the dam. Stream diversion systems used during
				construction shall be designed to provide protection to the dam and the safety
				of the public;
9. Construction
				control and inspection procedures shall be used during the construction of a
				new dam and reservoir or modification of an existing dam and reservoir.
				Construction control and inspection procedures should include compaction
				testing and density testing;
10.
				Procedures shall be used for recordkeeping and monitoring throughout the
				construction or modification process to provide information about any
				construction progress and conditions that may cause difficulties during
				construction;
11. The location of
				and protective measures used in conjunction with all drain lines, sewer lines,
				utilities, or other structures that pass through or under the dam;
12. Topographic surveys showing the location
				of baselines, centerlines, and other horizontal and vertical control points
				sufficiently accurate to locate the proposed construction and to define the
				volume of storage in the reservoir;
13. Two (2) sets of plans and specifications
				including-
A. Graphic scales for all scaled
				drawings;
B. The title, displayed
				identical on the plans and the specifications, shall include: the name of the
				dam; the name of the owner; whether the work shows an existing dam, a proposed
				dam or an enlargement, repair or alteration of the dam, or reservoir; the
				county(ies) the dam and reservoir are in; the location of the dam by quarter
				section, section, township and range, or by geodetic coordinates; and each
				sheet shall have in an appropriate title block the name of the dam as well as
				the sheet number in relation to the total, for example, sheet one (1) of twelve
				(12); and
C. Certifications by the
				experienced professional engineer and the owner shall be provided and be
				similar to those presented in figures 1 and 2 (see figures 1 and 2); and

14. If a construction permit is requested to
				convert a dam to a retaining or retarding structure, the procedure to be
				followed in making the conversion shall be described by the owner;
				and
15. The procedures set up for
				regular inspection by the owner. The owner shall develop an emergency action
				plan, inspect his/her dam regularly and as necessary to protect public safety,
				life and property. A list of items to be inspected, a time schedule for these
				inspections and a form for reporting the results shall be
				established.
