Stormwater Permit No. SW6210908

Dear Mr. Dooley and Mr. Cole:
The Division of Energy, Mineral and Land Resources (DEMLR), received a Stormwater
Management Permit Application for the subject project on September 30, 2021. A review of that
information has determined that the application is not complete. The following information is
needed to continue the stormwater review:
1. Please clarify the relationship between the Applicant, Bay Tree Solar, LLC, and the
project (Section III, Ic of the Application). The plans indicate that the developer is
Cypress Creek Renewables.
2. Per the provided USGS topographic map, there appears to be surface water located within
the project area, please do the following:
a. Please include the on -site surface water area in Section IV, 6 of the Application.
This information should also be included on Line 4 of the Cover Page of the
Supplement-EZ Form.
b. Please recalculate the total project are as shown in Section IV, 7 of the
Application. This information should also be updated on Line 2 of the Cover Page

oepm nt of EnvimnmwUl uwl ry 919.707.9200

of the Supplement-EZ Form, on Lines 5 & 6 of the Drainage Areas Page of the
Supplement-EZ Form, and in the table in Section IV, 10 of the Application.
c. Please recalculate the project percent impervious area as shown in Section IV, 8.
This information should also be updated on Line 18 of the Drainage Areas Page
of the Supplement-EZ Form and in the table in Section IV, 10 of the Application.
3. Please provide the original, signed and notarized hard copies of the signature pages of the
Application (Section VI, 1). The provided photocopies will not suffice. It is noted that
Harrison Cole's signature on one of the Applications is an original signature, however, all
of the signatures in one copy of the Application must be original.
4. Please provide calculations for the BUA summation for this project (Section VI, 7).
While the panels of the solar arrays may be considered as pervious (in accordance with
Part E-6 of the Stormwater Design Manual), the supports, foundations, and any other
related BUA are not. Please ensure that the calculations show that these associated BUAs
are being included in the BUA calculations.
5. Please clearly dimension the project area in the main set of plans with bearings and
distances (Section VI, 8i of the Application).
6. Please clearly identify and dimension all BUA in the main set of plans (Section VI, 8j). It
is noted that certain BUA (such as the inverter pads) is clearly dimensioned, however,
other BUA (such as the access roads and substation) do not appear to have enough
information to verify the BUA amounts. You may wish to add dimensioning to these
areas, callouts indicating the square footage of these areas, or a BUA table (similar to the
one in Section IV, 10 of the Application) to the plans. NOTE: Gravel areas that are
subject to infrequent vehicular traffic (approximately twice a month or less) can be
considered to not meet the definition of BUA per Part A-4 of the Stormwater Design
Manual (https:Hdeg.nc.gov/about/divisions/enemy-mineral-and-land-
resources/stormwater/stormwater-program/stormwater-design).
7. Please provide official documentation indicating that Harrison Cole has signatory
authority for the Applicant, Bay Tree Solar, LLC and that Patsy Barnhill has signatory
authority for one of the Property Owners, Blueberry Bay, LLC (Section VI, 11).
8. If you would like the solar panel surface areas to be considered pervious, you must
demonstrate compliance with recommendations 1-6 in Part E-6 of the Stormwater Design
Manual. You should discuss each of these items in the project narrative:
a. Recommendations 1, 3, & 4 — Please place a note in the plans and/or add special
O&M Agreement conditions/requirements (see attached example from a different
solar farm project) to avoid the compaction of the subsoils, to avoid the
concentration of stormwater runoff, and to minimize the use of herbicides and
fertilizers. These custom O&M Agreement items can be added into the O&M
Agreement Form using the "User Defined SCM".

b. Recommendations 2 & 6 — Please provide a detail for the solar panels showing
that a sufficient disconnection length is being maintained between the rows of
panels and that the vertical clearance of the panels is less than or equal to 10 feet.
Please also provide a slope map for the panel area so that the ground slope can be
determined.
c. Recommendation 5 — This item appears to be addressed in the permanent seeding
schedule.
9. Provide pdfs of all revisions, 2 hardcopies of revised plan sheets, 1 hardcopy of other
documents, and a response to comments letter briefly describing how the comments have
been addressed.
a. Pdfs must be uploaded using the form at:
https://edocs.deq.nc.gov/Forms/SW-Supplemental-Upload
b. Hard copies must be mailed or delivered to the following address:
i. For FedEx/UPS:

ii. For LISPS:

Please note that this request for additional information is in response to a preliminary review.
The requested information should be received by this Office prior to November 27, 2021, or
the application will be returned as incomplete. The return of a project will necessitate
resubmittal of all required items, including the application fee. Please reference the State
assigned project number SW6210908 on all correspondence.
If you need additional time to submit the information, please submit your request for a time
extension to the Division at the contact below. The request must indicate the date by which you
expect to submit the required information. The Division is allowed 90 days from the receipt of
a completed application to issue the permit.
The construction of any impervious surfaces, other than a construction entrance under an
approved Sedimentation Erosion Control Plan, is a violation of NCGS 143-215.1 and is subject
to enforcement action pursuant to NCGS 143-215.6A.
