Section 535.220 - Submission of application for approval of plans for decommissioning of dam1. A person who is required by NRS NRS 535.010 to file an application for approval of plans for the decommissioning of a dam must submit to the State Engineer in person or by mail: (b) Three copies of the plans and specifications, including, without limitation: (2) The specifications for construction; and(3) A set of plans. Each element of the plans and specifications must be prepared by or under the supervision of a professional engineer and must bear the wet stamp and signature of the professional engineer.
2. The application must: (a) Be on a form provided by the State Engineer;(c) Bear the original signature of each owner of the dam or an agent authorized to sign the application on behalf of the owner.3. The design report must include, without limitation: (a) A detailed description of the proposed work;(b) Discussions of: (1) The plan for release of water impounded by the dam;(2) The stabilization of sediment;(3) The anticipated consequences to persons and property located downstream from the dam;(4) Design features to prevent a sudden release of water or slope failure during decommissioning; and(c) If a breach in an embankment of the dam is designed with a bottom width that is less than the height of the embankment, calculations that establish the slope stability of the walls of the breach.4. The specifications for construction must:(a) Address all aspects of construction;(b) Include a schedule of testing for quality assurance and quality control;(c) Provide a precise citation to the location of any other common specification to which it refers;(d) Be on standard paper that is 8 1/2 by 11 inches in size; and(e) Set forth the sequence of activities, including a timetable.5. The plans must: (a) Depict the proposed work adequately and include, without limitation:(1) A cover sheet that includes, without limitation: (I) The name of each owner of the dam;(II) The name of the dam; and(III) A location plat that shows at least one section corner;(2) A second sheet which includes a plan view of the existing dam and impoundment that shows, without limitation: (I) The alignments of cross sections of the dam showing proposed alterations to the dam and impoundment;(II) The reference point of the dam, tied to a found section corner and identified by latitude and longitude; and(III) Section corners and elevation contours; and(3) A third sheet which includes a plan view of the dam and impoundment at the completion of decommissioning that shows, without limitation: (I) Details of proposed alterations to the dam and impoundment, including any new construction for the purposes of erosion control; and(II) Representative cross sections through the dam, breach and impoundment.(b) Show a tie with bearing and distance to a found section corner from a reference point on the existing dam. The reference point must be on the long axis at the station where the toe is at the lowest elevation. If no single point meets this criterion, the reference point must be at the intersection of the long axis and the centerline of the principle outlet.(c) Unless the use of exaggerated dimensions is necessary for clarity, have the same vertical and horizontal scales.6. For the purposes of determining whether a person is required to apply for approval of plans for the decommissioning of a dam pursuant to paragraph (b) of subsection 2 of NRS NRS 535.010, the State Engineer will calculate the capacity of the dam as the volume of water, expressed in acre-feet, detained above the anticipated elevation of the lowest point on the toe of the dam.7. As used in this section, "decommissioning" includes breaching and removing.Nev. Admin. Code § 535.220
