4. Proposed Activity
Provide a detailed description of the proposed activity including its purpose and include the type of equipment to be used:*

The proposed project is construction of an aggregate quarry, with associated work
roads and utilities, to meet increased aggregate demand in North Carolina.
The project requires the construction of an entrance roadway connecting the quarry
operations with Clark Road. This roadway will create access to the main business
office, providing access for the employees and customers, and continue into the
mining area, providing access for mining equipment and service vehicles.
Based on the mining plans, the entrance is required to be located on the west side
of the mine, avoiding the internal mining operations. For this purpose, the proposed
roadway will require crossing of an unnamed tributary (Stream 3 on the USACE
PJD), which originates near the center of the project and courses west to the
western property boundary.
The proposed entrance roadway will utilize a bottomless culvert, designed to be
seated on subsurface rock. For this design, the subsurface rock elevation is
assumed to be appro)amately the elevation of the rock stream bed. The culvert has
been sized to allowfor construction without disturbance of the stream channel,
providing for 11 ft of channel bankfull clearance (actual channel width = 4.9 ft), and
an additional 6 feet of clearance on each side of the channel (see attached site
plans).

6a. Have permits or certifications been requested or obtained forth is project (including all prior phases) in the past?*
r Yes
r No
7. Future Project Plans
7a. Is this project a phased project?* r Yes
b No
7b. If yes, explain*
The Snow Camp Mine is expected to be in operation for decades, mining different
sections of the property over different future phases and time periods. The property
is well suited for upland development, and with consideration to potential - and very
general - expansion plans, there are no intended or anticipated future activities that
will require authorization.
In addition, the current mining plans and operations, for which this authorization is
required, will meet the project goals and needs of the applicant as a single and
complete project.

D. Impact Justification and Mitigation
1. Avoidance and Minimization
....................................................................................................................................................................................................................................................................................................................................................................................................................................................-..........

1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project.*
Prior to site design, the applicant requested a delineation of wetlands, streams, and
riparian buffers, in order to avoid impacts where practicable.
Due to the design of the mine, including the location of the office and the internal,
upland mining operations, the access road is required to be situated on the western
side of the project, which requires the crossing of Stream 3.
Alternatively, constructing the roadway to the east would result in the access road
terminating into the mining operations.
The use of the bottomless culvert avoids impacts to the stream channel, and the
crossing is located in an area where no wetlands are present, avoiding wetland
impacts.
The proposed roadway is designed to cross the stream in a relatively straight reach,
perpendicular to the stream channel, minimizing the total riparian impact footage.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.*
Access road construction will be performed under an approved Sediment and
Erosion Control Plan, implemented through the NC Division of Energy, Mining, and
Land Resources.
Access to the work area will be from high ground, and construction mats will be used
if necessary. Use of heavy equipment within the riparian buffer will be avoided as
much as possible.
Permanent impacts have been minimized to least extent necessary, and
unavoidable temporary construction impacts will be restored to pre -construction
contours, re -planted, and remain undisturbed post -construction.
When possible, construction will be performed during dry periods to avoid heavy
rain events.
E. Diffuse Flow Plan
......... ......... ......... ......... _...._... .._...... ......... ......... .......... ....... ....... ....... .........
la. What type of SCM are you providing?*
r Level Spreader
F Vegetated Conveyance (lower SHWT)
r Wetland Swale (higher SHWT)
rJ Proposed project will not create concentrated stormwater flow through the
buffer
r Other SCM that removed minimum of 30% nitrogen
