1.4 Facility and Activities
Facilities
The Quartz Corp USA,Olerud Mine is located just east of Spruce Pine, NC on Altapass Road,off
highway 19E. The Mine will be provided with a private entrance on Roan Road which will provide access
to the areas of activity. another entrance and exit point off 011is Road will be established and will be used
for emergencies (see attached map).
The basic function of the site is to provide a site to land apply mine overburden and mineral tailings from
an industrial mineral mine and processing plant which produces industrial minerals for use in the semi-
conductor,quartz,ceramic and glass industries.
The site is 114 acres in size and has stormwater controls as required by a Mining Permit which is
expected to be issued by The North Carolina Department of Environmental Quality, Division of Energy,
Minerals and Land Resources, Land Quality Section.
Activities at the mine are all mobile and there are no buildings or offices on site. There is no shop to
service loaders, drills,trucks and other heavy equipment and major repairs and service is performed off-
site. Solvents,oils, lubricants and other fluids are stored in the service trucks but only in small
quantities. There are no stationary fuel tanks planned for use at the site.

Mine Activities
Activities at the Olerud Mine are not normal for an Industrial Mining operation because no minerals will be
mined but rather placed at the site. This operation will need infrastructure such as roads and erosion
controls which will be performed by excavating and building roadways,and drilling and blasting only as
needed for road access. Trees and other naturally occurring debris are disposed of on and off site
according to law and all metal, and other recyclable materials are recycled according to local,state and
federal regulations. The mine area is supplied with wide haul roads to accommodate the larger
equipment and allow them to move about safely and without delay. Active areas of the mines are bare
and not vegetated and runoff is directed to sediment basins which are designed for 25-year reoccurring
storm events. Dusts from the haul roads are controlled and treated with water, which flows to the
sediment basins or evaporates. Tailings application areas will be supplied with Basins to control runoff
before it leaves the site and are seeded as the fill area is developed.
All stormwater controls at the Olerud Mine have been sent for approval to the NC DEQ division of Land
Quality for approval in the mining permit.

2.3 Non-Storrnwater Discharges Documentation
• Date of evaluation for last non-stormwater discharge: (May, 2020 benchtop)
• The evaluation criteria used,was a site inspection of the Olerud Mine and no non-stormwater
discharges were noted.
• All Stormwater Discharge points that exist were directly observed during the evaluation:
• No different types of non-stormwater discharge(s)and source locations:were found or observed
during inspection with the exception of a small number of naturally occurring springs which flow
during wet periods and after heavy rains.
No action(s)were taken or necessary as a result of the inspections.
2.4 Sampling Data Summary
Stormwater sampling will be determined by the permit once issued and the resulting data attached as
Attachment G

SECTION 3: STORMWATER CONTROL MEASURES
3.1 Minimize Exposure
1. Skimmer Basins
The site will have skimmer basins designed that provide metered release of the runoff from portions of the
site.These basins are designed to store and release(over a two-day time period)the rainfall from an estimated
25 year; 24-hour storm event. See attached construction details and maintenance procedures.
2. Hardware Cloth&Gravel Inlet Protection
The gravel filter inlet structure prevents the conveying of solids and other materials oftsite during stormwater
runoff events.See attached construction details and maintenance procedures
3. Grass Ditches
Grass ditches catch and remove dust,sediment and small solids from the stormwater runoff as it is conveyed
through the site.
4. Rip Rap Ditches
Rip rap ditches catch and remove sediment from stormwater runoff and decrease velocity in the ditch preventing
scouring,erosion and soil and sediment loss as the runoff is conveyed through the site.
4. Sediment fence
All mine boundary areas will be supplied with sediment fence to protect the stream buffers and adjoining
Properties from sediment in areas not supplied with other controls such as berms and ditches
5. Proper equipment fueling
Large off-road vehicles need to be fueled by a mobile fuel truck and those truck drivers and the contractors
shall be trained to properly dispense fuel without spills and or leaks and also how to react to spills.
6. Fugitive Dust Plan
Fugitive dusts can be a problem in areas of heavy truck traffic and a fugitive dust control plan has been
prepared for the site which will control accumulating dusts which be conveyed into streams by stormwater flow.
3.2 Good Housekeeping
The entire site must be kept clean of any trash or debris that may become airborne and enter a
stormwater conveyance. No trash or other debris will be allowed to collect at the site that may become a
stormwater pollutant contributor. Any and all spills of liquids,fluids, petroleum products and oil shall be
cleaned up immediately and the cleanup materials shall be stored covered, until they are disposed of.
All materials used to clean these small spills are disposed of in a manner regulated under federal,state
and local laws.

13 Maintenance
Several types of maintenance shall be conducted at the Mine, all of which are performed to allow the
runoff control structures to perform at the top level of efficiency. All sediment controls are to be inspected
after each runoff producing rainfall event and at least once per month. Sediment fence that is no longer
effective shall be replaced on an as needed basis. Sediment traps, basins and skimmer basins shall be
cleaned when the level of sediment is at 50%of pool capacity. Baffles in sediment basins and traps shall
be replaced when they no longer function properly. Clean stone used for filtering will be replaced when
the stone no longer filters the runoff and allows runoff to pool.
All paved areas will be swept or blown clean after each mowing to prevent grass clippings from being
conveyed off site by runoff. Bare soil areas will be seeded and reseeded as needed to provide a grass
covered area. Any landscaping, brush clearing,weed eating and other yard and site maintenance shall
be performed in a manner to collect any materials that can clog drains or be carried offsite by runoff.
Maintenance of heavy equipment shall be performed offsite when possible and feasible and if performed
outside, containers shall be used to collect fluids and oils and a spill kit shall be available to clean up any
accidental spills. Tarps shall also be available to cover outside work during times of precipitation.
3.4 Spill Prevention and Response
Spill clean up materials shall be kept at the site and a small kit will be provided on service trucks for the
cleanup of spills, accidents and other emergencies at the site. Each area shall be supplied with a spill kit
capable of cleaning up,collecting or preventing loss in the general work area.
3.5 Erosion and Sediment Controls
Any fill or construction areas and the associated haul roads and travel ways,shall be supplied with
sediment fence, berms,ditches and sediment control structures sufficient to retain sediment on site.
These structures are shown on the mine permit plan sheets and will be approved for the size and location
shown on the mine permit drawings.These structures are primary structures and the runoff would flow
through them and a final stormwater control before being discharged from the site.
3.6 Management of Runoff
Stormwater runoff is controlled at the site by the use of surface drains,ditches,swells, culverts, basins
berms,skimmers and other controls. All conveyance structures are to be inspected at least annually and
after major storm events.
3.7 Stormwater Pollution Prevention Training
Please see attached training forms for Management, all individual plant employees, maintenance
personnel,delivery personnel and other persons who may conduct business at the Duncan Mine facility
that may affect, impact or contribute to pollution in stormwater runoff.

3.8 Non-Stormwater Discharges
A small number of natural small streams are present onsite and discharge water during storm events and 1114�
briefly afterwords.
3.9 Waste, Garbage and Floatable Debris
All Mine areas must be kept clean of any trash or debris that may become airborne and therefore a
stormwater pollutant contributor.
3.10 Dust Generation and Vehicle Tracking of Materials
Because the Olerud Mine areas will be growing and active there are un-vegetated areas,gravel lots, haul
roads, and roadways which produce fugitive dusts. These areas are generally considered stable and non-
erosive but there is dust generated by the vehicle traffic in these areas. Once this dust has fallen onto the
paved areas and roofs it is washed off by stormwater runoff. There are also fill areas which create dust that
is also conveyed onto areas that convey runoff. This dust(sediment)is also washed away and conveyed
by stormwater to the final controls where it is collected from the runoff by control structures.A fugitive dust
plan has been prepared for this site and will be implemented as a part of the operation.

SECTION 4; SCHEDULES AND PROCEDURES FOR MONITORING
1. Sample Location(s).
All stormwater samples will be taken at the Stor nwater Discharge Outfall(SDO)and at the location(point)
where the flow of runoff leaved the property or control structure. Representative sampling may be
established after a review of the sampling data and approval by the permitting authority. See attached
General Permit for additional details.

3. Procedures.
All samples are to be collected as shown in 4:1 above,and in accordance with the Stormwater Permit.if
samples are stored,they shall follow the general guidelines for sample storage,holding times,chain of
custody, record keeping and other requirements as necessary to preserve and guarantee the integrity of the
sample
Qualitative monitoring requires a visual inspection of each stomwmter discharge outfall(SDO)associated with
airport activity regardless of representative outfall status and shall be performed as specified above.
Qualitative monitoring of stormwater outfalls must be performed during a representative storm event. A
representable rainfall event is a storm event that measures 01 inches of rainfall and that is proceeded by at least
72 hours in which no storm event that measures 0 l inches has occurred. Visual examinations must be made on
samples collected within the first 30 minutes(or as soon thereafter as practical, but not to exceed 1 hour)of
when the runoff or snowmelt begins discharging from the outfall.Or as the permit directs.
a. The visual examination must be made during daylight hours.If no storm event resulted in runoff
during daylight hours from the facility during a monitoring period,the Permittee is excused from
the visual monitoring requirement for that period;provided the Permittee documents that
no runoff occurred.
b. In the event an atypical condition is noted at a stonmwater discharge ouUWI,the permittee
shall document the suspected cause of the condition and any actions taken in response
to the discovery.This documentation will be maintained on-site for a period of five years and
made available to the Director or his/her authorized representative immediately upon request.
C. Visual examination reports must be maintained onsite or in the manager's office in the case of no
onsite office.The report must include the examination date and time,inspection personnel,nature of
the discharge(i.e.,runoff or snow melt),visual quality of the stormwater discharge(including
observations of color,odor,clarity,floating solids,settled solids,suspended solids,foam,oil
sheen,erosion or deposition at the outfall,and other obvious indicators of stormwater pollution),
and probable sources of any observed stormwater contamination.
