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