Restoration Plan for Temporary Riparian Buffer Impacts
Snow Camp Mine
Alamance County
DWR# 20200320
April 15, 2020
This plan is submitted to the NCDWR/WSRO to provide additional detail regarding restoration of
the temporary riparian buffer impacts associated with the construction of a service road for the
Snow Camp Mine facility, Snow Camp, Alamance County NC.
A Location Map for the facility is included as Attachment 1.
Restoration Goal
The goal of the restoration plan is re-establishment the riparian buffer, approximating the current
pre -construction conditions, as well as conditions specified in 15A NCAC 213 .0267(7)(a) and (b).
This plan generally follows DWR Memorandum #2006-003 Temporary Road Vegetation
Management.
Proposed Temporary Impacts
The proposed road will provide the main access to the facility, crossing Stream 3. The location of
the proposed road crossing is included as Attachment 2. The detail of the road crossing, including
permanent and temporary impacts, is included as Attachment 3 Bridge Culvert Impact Figure,
dated 1/21/2020. Note: all construction work will be conducted under an approved Erosion and
Sediment Control (ESC) plan.
Temporary impacts will occur on both the east and west side of the service road. The temporary
impact total for the project is 4,883 square feet (sf). A summary of impacts for the project is as
follows:

Total Impact (sf)

9,483
Existing Conditions
Generally, the riparian buffer in the subject area is considered forested (>10% tree cover), with
existing cover provided by mature hardwood forest vegetation of poplar (Lirodendron tulipifero),
and water oaks (Quercus nigra), and a dominant herbaceous grass cover of approximately 80%
(0 Page 1

microstegium (Microstegium vimineum) and 20% common sedge (Carex spp). There is very little
to no sapling/shrub cover present in the crossing area.
Although the mature forest canopy cover is approximately 100 percent, the total number of trees
present is low.
Construction activities will avoid tree removal where possible. If removal is required, trees will be
replanted in the areas where trees were removed.
Restoration Actions
Following completion of the crossing, the temporary impact areas on both sides of the crossing
will be restored to preconstruction contours, smoothed, and seeded with a stabilizing grass seed
mix.
Once the grass cover is established and temporary impact areas are stabilized, the ESC measures
will be adjusted in the field and these areas will be removed from the Area of Disturbance. The
impact areas will be allowed to naturally revegetate (unmaintained) over time.
If construction requires the removal of trees, each tree removed will be replaced in or near the
area where the tree was removed. Planted trees will be ball & burlap or bare root, with minimum
2.5" DBH, warrantied for 1 year. Replacement trees will be planted during the first raining season
(Nov — Feb) following completion of the crossing.
Tree species will be selected from the attached table, included as Attachment 4. Replacement
trees will be selected by specific site conditions (region/light/moisture).

Note: A Boundary Fence will be
installed in this approximate area,
crossing through the riparian
buffer perpendicular to Stream 3.
Disturbance will be minimized and
there will be no removal of trees.
There is no associated
maintenance corridor. This activity
is exempt under 15A NCAC 02B .
