11 Miss. Code. R. 7-3.3 - Application Content and Procedure

A. Any person or entity proposing to construct, enlarge, repair, or alter a dam or reservoir shall submit either an application or a pre-construction notification (if the provisions of Rule 3.2 B. apply) to the Board, on forms prescribed by the Board, at least thirty (30) days prior to the anticipated commencement of construction. The submittal must have a United States Geologic Survey (USGS) topographic map, or portion thereof, attached to it showing the location of the proposed dam and reservoir including a clearly marked access route to the site and marked locations and general descriptions of all buildings, drainage structures or culverts, roads, railroads, bridges, and utility lines within two-miles downstream of the site of the proposed dam.

B. If the provisions of Rule 3.2. B. do not apply, or if the dam is classified as high or significant hazard as defined by these regulations, the application package also must include a complete set of design documents prepared in accordance with the following requirements:

(1) Engineering drawings, specifications, and engineering reports shall be prepared, signed, and sealed by a professional engineer. Engineering reports shall include, but not be limited to, hydrologic calculations, hydraulic calculations, geotechnical investigation, and provisions for internal drainage to address through-seepage and under-seepage. Portions of the investigation at the site of the dam and within the catchment area including, but not limited to, characterization of geologic formations, assessment of groundwater conditions, and/or other geologic conditions, factors, and processes which may impact the design of the dam may be performed by a professional geologist.

(2) Drawings shall be prepared to a scale that provides sufficient detail for review of all project components.

(3) Specifications shall include detailed descriptions of all work to be performed and materials to be used in the construction, including plans for diversion during construction and quality assurance and quality control.

(4) A geotechnical report showing the foundation conditions and material properties at the location of the dam as well as the classification and material properties of all borrow material must be submitted for the construction of all new high and significant hazard dams.

(5) For high and significant hazard dams a proposed construction schedule detailing the critical stages including but not limited to construction of the cutoff trench, spillways, and filters must be submitted prior to the commencement of construction.

C. Application packages for a low hazard dam shall include, but not be limited to, a plan view of the dam (including all appurtenant works) and sections through the dam at the centerline of the principal spillway and at the centerline of the auxiliary (emergency) spillway.

D. The Board may require the applicant to supply any additional information necessary to evaluate an application, including the following:

(1) Whether the proposed dam will provide adequate safety for lives and property; and/or

(2) Whether the proposed dam will adversely affect riparian or other beneficial water uses, or plans for the proper utilization of the water resources of the state, and/or

(3) Any other information the Board deems appropriate.
