(BUA) and vegetated conveyances associated with the subject project.
This permit shall be effective from the date of issuance until rescinded and the project shall be
subject-to-the-conditions-and-limitations-as-specified-therein-and-does-not-supersed'e-any-other—
agency permit that may be required. Failure to comply with these requirements will result in
future compliance problems. Please note that this permit is not transferable except after notice to
and approval by the Division.
This cover letter, attachments, and all documents on file with DEMLR shall be considered part
of this permit and is herein incorporated by reference.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the

STATE STORMWATER MANAGEMENT PERMIT
LOW DENSITY DEVELOPMENT
In compliance with the provisions of Article 21 of Chapter 143, General Statutes of North
Carolina as amended, and other applicable Laws, Rules, and Regulations promulgated and
adopted by the North Carolina Environmental Management Commission, including 15A
NCAC 02H.1000 amended on January 1, 2017 (2017 Rules) (the "stormwater rules"),
PERMISSION IS HEREBY GRANTED TO
Snow Camp Solar, LLC
9200 Snow Camp Rd, Snow Camp, Alamance County
FOR THE
construction, management, operation and maintenance of built -upon area (BUA) for a 24%
low density project (the "low density area") discharging to Class WS-V;NSW waters as
outlined in the application, approved stormwater management plans, supplements,
calculations, operation and maintenance agreement, recorded documents, specifications,
and other supporting data the "approved plans and specifications") as attached and/or on
file with and approved by the Division of Energy, Mineral and Land Resources (the
"Division" or "DEMLR"). The project shall be constructed, operated and maintained in
accordance with these approved plans and specifications. The approved plans and
specifications are incorporated by reference and are enforceable parts of this permit.
This permit shall be effective from the date of issuance until rescinded and shall be subject
to the following specified conditions and limitations. The permit issued shall continue in
force and effect until the permittee files a request with the Division for a permit
modification, transfer, or rescission; however, these actions do not stay any condition. The
issuance of this permit does not prohibit the Director from reopening and modifying the
permit, revoking and reissuing the permit, or terminating the permit for cause as allowed
by the laws, rules, and regulations contained in 15A NCAC 2H.1000 and NCGS 143-215.1
et.al.
1. BUA REQUIREMENTS. The maximum amount of BUA allowed for the entire project is
48,783 square feet. The BUA requirements and allocations for this project are as
follows:

a. LOW DENSITY AREA BUA LIMITS. The low density area, also referred to as
Drainage Area 1 in the approved plans and specifications, must not exceed 24%
per the requirements of the stormwater rules. Within Drainage Area 1, this permit
approves a percent BUA of 4.42% and the construction of a total of 48,783 square
feet of BUA. Drainage Area 1 does not include any allocation for future BUA.
2. PERVIOUS AREA IMPROVEMENTS. The following types of improvements are
included in the project and considered pervious per the stormwater rules:
a. SOLAR FARM. In order for the solar panels to be considered a pervious surface, all
of the recommendations of Chapter E-4 of the Stormwater Design Manual must be
met. This solar farm has proposed a variation to the recommendations in Chapter
E-4 of the Stormwater Design Manual, which includes falling short of the 80%
recommended disconnection length by 7.4 % but has been found to qualify as a
pervious surface due to the panels being significantly lower than the 10 foot
height threshold to prevent any erosion and scouring along the drip line.
3. LOW DENSITY AREA REQUIREMENTS. The low density area requirements for this
project are as follows:
a. LOW DENSITY AND CONVEYANCE DESIGN. The low density area is permitted
based on the design criteria presented in the sealed, signed and dated supplement
and as shown in the approved plans and specifications. This low density area and
conveyances must be provided and maintained at the design condition.
amounts of piping under driveways and roads is allowed within fhe low density
area when it cannot be avoided. No additional piping is allowed.
c. DISPERSED FLOW. The low density area has maximized dispersed flow of
stormwater runoff through vegetated areas and minimized the channelization of
flow.
d. VEGETATED CONVEYANCES. Stormwater runoff that could not be released as
dispersed flow may be transported by vegetated conveyances with minimum side
slopes of 3:1 (H:V) designed to not erode during the peak flow from the 10-year
storm event as defined in the stormwater rules and approved by the Division.
4. STORMWATER OUTLETS. This project does not propose any discharge points and
therefore will not have the opportunity to cause erosion during the 10-year storm
event
5. VEGETATED SETBACKS. A 30-foot wide vegetative setback must be provided and
maintained in grass or other vegetation adJ'acent to all surface waters as shown on the
approved plans. The setback is measured horizontally from the normal pool elevation
of impounded structures, from the top of bank of each side of streams or rivers, and
from the mean high waterline of tidal waters, perpendicular to the shoreline.
a. BUA IN THE VEGETATED SETBACK. BUA may not be added to the vegetated
setback except as shown on the approved plans or in the following instances
where the BUA has been minimized and channelizing runoff from the BUA is
avoided:
i. Water dependent structures; and
ii. Minimal footprint uses such as poles, signs, utility appurtenances, and
security lights that cannot practically be located elsewhere.

6. RECORDED DOCUMENT REQUIREMENTS. The stormwater rules require the
following documents to be recorded with the Office of the Register of Deeds:
a. ACCESS AND/OR EASEMENTS. The entire stormwater conveyance system and
maintenance accesses must be located in public rights -of -way, dedicated common
areas that extend to the nearest public right-of-way, and/or permanent recorded
easements that extend to the nearest public right-of-way for the purpose of
inspection, operation, maintenance, and repair.
b. OPERATION AND MAINTENANCE AGREEMENT. The operation and maintenance
agreement must be recorded with the Office of the Register of Deeds.
c. FINAL PLATS. The final recorded plats must reference the operation and
maintenance agreement and must also show all public rights -of -way, dedicated
common areas, and/or permanent drainage easements, in accordance with the
approved plans.
7. MODIFICATIONS. No person or entity, including the permittee, shall alter any
component shown in the approved plans and specifications. Prior to the construction
of any modification to the approved plans, the permittee shall submit to the Director,
and shall have received approval for modified plans, specifications, and calculations
including, but not limited to, those listed below. For changes to the project that
required and a copy must be submitted to the appropriate DEQ regional office upon
completion of the modification.
a. Any modification to the approved plans and specifications, regardless of size
including the BUA, details, etc.
b. Redesign or addition to the approved amount of BUA or to the drainage area.
c. Further development, subdivision, acquisition, lease or sale of any, all or part of
the project and/or property area as reported in the approved plans and
specifications.
d. Altering, modifying, removing relocating, redirecting, regrading, or resizing of any
component( the approved stormwater collection system and/or vegetative
conveyance shown on the approved plan'
e. The construction of any allocated future BUA.
f. The construction of any permeable pavement, #57 stone area, public trails, or
landscaping material to be considered a permeable surface that were not included
in the approved plans and specifications.
g. Other modifications as determined by the Director.

8. CONSTRUCTION. During construction, erosion shall be kept to a minimum and any
eroded areas of the on -site stormwater system will be repaired immediately.
a. PROJECT CONSTRUTION, OPERATION AND MAINTNEANCE. During construction,
all operation and maintenance for the project and stormwater system shall follow
the Erosion Control Plan requirements until the Sediment -Erosion Control devices
are no longer needed.
b. FINAL GRADING. The vegetated areas and vegetated conveyances shall be entirely
constructed and vegetated. Once the final grading is completed and the site is
stabilized, the permittee shall provide and perform the operation and
maintenance as outlined in the applicable section below.
9. DESIGNER'S CERTIFICATION. Upon completion of the project, the permittee shall
