NAC445A.397. Contents of application: Engineering design report; specifications for fluid management system.

     1. An engineering design report must be prepared and submitted to the Department by a professional engineer registered in Nevada. The report must include the following information, if applicable:

     (a) Engineering plans for the process components used for beneficiation;

     (b) The general specifications and calculations for the process components;

     (c) Topographic maps showing the location of all potential sources at the facility including, but not limited to:

          (1) The extraction sites;

          (2) The process components used for beneficiation;

          (3) The disposal sites for waste rock; and

          (4) The disposal sites for spent ore;

     (d) Drawings which indicate the layout of the structures and devices for controlling process fluids;

     (e) Methods for the control of storm flow runoff;

     (f) The existing geological and hydrogeological conditions beneath and adjacent to the site of the fluid management system and waste rock disposal sites and the degree to which these conditions provide natural containment, preferential flow pathways and structural stability;

     (g) A description of the liner material and installation procedures for all leach pads, ponds and ditches, including a description of the subbase preparation;

     (h) Details of leak detection and site-monitoring systems; and

     (i) Process schematics of the facility.

     2. Specifications for constructing the fluid management system and for the material to be used must be submitted to the Department with the application for a permit, and must include, but not be limited to, the methods to be utilized for inspecting, testing, and quality assurance and control.

     3. The information required by subsections 1 and 2 must be of sufficient detail to allow the Department to make the following factual determinations:

     (a) Which of the potential sources at the facility are to be considered process components for the purposes of NAC 445A.350 to 445A.447, inclusive;

     (b) That the design of the process components is sufficient to protect the waters of the State from degradation; and

     (c) That the monitoring system is adequate to determine if the process components are operating so as to protect the waters of the State from degradation.

Ê Any material modification to a process component requires the approval of the Department before construction begins.
