1. Submit payment of the penalty, OR
2. File a request for remission of civil penalties, OR
3. File a written petition with the Office of Administrative Hearings.
Failure to exercise one of the above three options within thirty (30) calendar days of your receipt of
these documents will result in this matter being referred to the Attorney General's Office with a request
to initiate a civil action to collect the penalty.
These options are detailed below:

Option 2 — File a request for remission of civil penalties:
A request for remission or mitigation is limited to consideration of the reasonableness of the
amount of the penalty and is not the proper procedure for contesting the accuracy of any of the
statements contained in the assessment letter.
Because a remission request forecloses the option of an administrative hearing, such a request
will not be processed without a waiver of your right to an administrative hearing and a
stipulation that there are no factual or legal issues in dispute.
You must execute and return to this office the attached "Waiver of Right to an Administrative
Hearing and Stipulation of Facts" and the attached "Justification for Remission Request" which
should describe why you believe:
(a) one or more of the civil penalty assessment factors in G.S. 143B-282.1(b) were wrongfully
applied to the detriment of the petitioner;
(b) the violator promptly abated continuing environmental damage resulting from the
violation;
(c) the violation was inadvertent or a result of an accident;
(d) the violator had not been assessed civil penalties for any previous violations;
(e) payment of the civil penalty will prevent payment for the remaining necessary remedial
actions.
For this option you must file your request for remission of civil penalties within thirty (30)
calendar days of receipt of this notice. Submit this information to the following:

AND ASSESSMENT OF
FOR VIOLATIONS OF: ) CIVIL PENALTIES
15A NCAC 02H .0500, and )
15A NCAC 02B .0231 )
Acting pursuant to North Carolina General Statute (hereby known as G.S.) 143-215.6A, I,
Jeffery O. Poupart, of the Division of Water Resources (hereby known as DWR), make the
following:
I. FINDING OF FACT
A. Duke Energy Renewables NC Solar, LLC was listed as the financially
responsible party for land disturbing activities for the site known as the
Windsor Solar Site, per records from the Division or Energy, Mineral and
Land Resources (herby known as DEMLR), located off Cooper Hill Road in
Bertie County, North Carolina.
B. Duke Energy Renewables NC Solar, LLC is a company organized and
existing under the laws of the State of North Carolina.
C. On December 9, 2016, DWR received an after -the -fact 401 Water Quality
Certification (hereby known as WQC) application for wetland impacts at the
Windsor Solar site. SunEnergyl, LLC was listed as the applicant.
D. SunEnergyI, LLC is a company organized and existing under the laws of the
State of North Carolina.
E. According to DWR records, SunEnergyl, LLC was responsible for the
Windsor Solar Site during its construction phase.
F. On February 16, 2017, representatives from the DWR conducted a site
inspection of the constructed Windsor Solar Site. Accompanying DWR were
staff from DEMLR, the US Army Corps of Engineers (hereby known as

Duke Energy Renewables NC Solar, LLC and Sunaergyl, LL.0
Bertie County
Windsor Solar WP-2017-0001
Page 2 of 5
USACE), representatives from Duke Energy Renewables NC Solar, LLC,
representatives of SunEnergyl LLC, and representatives from Carolina
Ecosystems, Inc. DWR inspected the access road and two areas of installed
solar panels. On the southern area of installed panels, the USACE confirmed
that jurisdictional wetlands had been impacted from grading, earthen fill, and
the installation of solar panels, associated infrastructure, and road
improvements.
G. A review of DEMLR's Erosion & Sedimentation Control Plan files shows a
wetland area in the southern field of installed panels to be avoided.
H. The after -the -fact 401 WQC application received on December 9, 2016 did
not propose the extent of impacts observed during the February 16, 2017 site
visit.
I. A DWR file review confirmed the impacts noted above to approximately 0.7
acres of wetlands occurred without the issuance of a 401 Water Quality
Certification.
I On February 17, 2017, the 401 WQC application was withdrawn by the
request of SunEnergyl, LLC.
K. The water quality standards for wetlands, as found in Title 15A North
Carolina Administrative Code (hereby known as NCAC) 02B .0231(a), are
designed to protect, preserve, restore and enhance the quality and uses of
wetlands and other waters of the state influenced by wetlands.
L. Title 15A NCAC 02B .0231(b)(1) requires "Liquids, fill or other solids or
dissolved gases may not be present in amounts which may cause adverse
impacts on existing wetland uses;"
M. Title 15A NCAC 02B .0231(b)(5) requires "Hydrological conditions
necessary to support the biological and physical characteristics naturally
present in wetlands shall be protected to prevent adverse impacts on: (C) The
chemical, nutrient and dissolved oxygen regime of the wetland; (D) The
movement of aquatic fauna; and (F) Water levels or elevations."
N. Title 15A NCAC 02H .0500 requires water quality certifications pursuant to
Section 401 of the Clean Water Act whenever construction or operation of
facilities will result in a discharge into jurisdictional waters, including
wetlands, as described in 33 CFR Part 323.

LLC and SunEnergyl, LLC received the NOVRE on February 28, 2017 and
February 27, 2017 respectively.
P. DWR received written responses to the NOVRE from Duke Energy
Renewables NC Solar, LLC and from Beveridge & Diamond, P.C., attorney
for SunEnergyl, LLC. The responses proposed removing solar panels from
the wetlands, restoration and possible permitting. To date, a restoration and
permitting plan has not yet been finalized or approved.
Q. The impacts occurred to wetlands, Class WL waters, within the Roanoke
River Basin.
R. The cost to the State of the enforcement procedures in this matter totaled
1 029.26.
Based upon the above Finding of Fact, I make the following:

Carolina Ecosystems, Inc., on behalf of SunEnergyl, has prepared the attached Pre -Construction
Notification (PCN) for the above referenced project for a Clean Water Act Section 404
Nationwide Permit 39.
This is an after -the -fact permit application because the solar site has already been installed.
SunEnergyl recognized this oversight and immediate steps were taken to notify you and prepare
the appropriate documents.
The attached PCN form provides information for use in your review of the impact to one wetland
associated with this site. Supplemental information is provided in this cover letter. Additional
information is contained in the attachments including a Vicinity map, USGS map, and
Jurisdictional Features map.
Proposed Impacts and Mitigation
Only one impact is associated with this project: 0.31 ac of wetland (WA on attached
Jurisdictional Features Map). This riparian wetland was forested before being cleared and filled
for the installation of solar panels. Compensatory mitigation will be required through an in -lieu
fee program (Attachment 5). Sediment and erosion control measures were implemented
according to NC requirements, and approved by NCDEQ prior to implementation.

Thank you for updating me on the information. I will contact the USFW and discuss this project with the existing
information supplied with the submittal. Due the nature of this being an After the Fact application I do need to go
through the coordination process to cover my review of the federal regulations. Once I have done that I will contact you

Good Morning, Everyone:
Kyle and I are playing phone -tag on this one. For everyone's benefit, I'm sending along our response to ensure no delay
in review. Once we're able to speak about steps to shake this loose, I'll copy everyone on the resolution.
This project was built prior to the listing of NLEB. No additional clearing has occurred or is proposed. A review of Google
Earth historic photos will show that as of January 19, 2014, the site had been built. The NLEB was listed on April 2, 2015.

Thanks in advance for communicating any outstanding concerns at your earliest convenience.
Happy Holidays,
Chris

Chris,
I have received the NWP application for the after the fact impacts associated with the SunEnergyl installation of
Windsor Solar. I reviewed the PCN and noticed that the Endangered Species section is incorrect and does not provide
sufficient information to make a determination that the project does not have an effect on endangered species. The
Northern Long Eared Bat (NLEB) is a listed endangered species by the USFW. You indicated that you reviewed the USFW
website and contacted the Raleigh Office for conformation that the project is in compliance with Section 7 of the
Endangered Species Act. Did you receive any documentation indicating that you had discussed the project and they
agreed there would be "No Effect' to endangered species because Bertie County is listed as a county with accounts of
NLEB. This link takes you to the information I described above and is part of the Raleigh Field Office website,
httPs://www.fws.gov/raleigh/NLEB—RFO.html.
If you do not have information that you can provide indicating that a "No Effect' determination was made I will have to
consider the current request as incomplete. Coordination with the USFW is required to complete a permit decision and
potentially resolve any Endangered Species issues of concern.
Let me know if you have that information or have coordinated with the USFW on this topic.
If you have any questions please feel free to contact me at the number listed below or by email.

Windsor Solar Site
Eric,
This correspondence is to inform you that new information has surfaced indicating that the wetlands on the Windsor
Solar site, for which you have submitted an after -the -fact PCN application for wetland fill, are potentially more extensive
than identified during our site visit on September 14, 2016. At this point your application requesting to permit existing
fill within wetlands on the site is still incomplete.
It is my suggestion that we conduct another site visit with the new information to identify the extent of the jurisdictional
areas on the site. Additionally it would be beneficial to include the Division of Water Resources and a representative
from DEMLR to discuss all permitted activities that have taken place on the site.

Eric,
At this point with the new information that has come to light it is likely that the Corps will be retiring your application for
a Nationwide Permit (NWP) for existing impacts to Waters and Wetlands of the US. New information indicates that the
impact area is larger than what could have been allowed under our NWP thus nullifying the original application. I will not
officially retire the file until after the site visit on February 16th giving us the opportunity to review potential impacts we
were unaware of during the last site visit.

The plan is to meet everyone onsite at 10am. Assume Anthony will give us info on the exact meeting location (or if it's
best to just meet them at WaRO and carpool from there). Planning to see two sites: one near Windsor, one near

No. I just spoke with Kelly Hoyt who confirmed there has been no disturbance to that area. My understanding is that
DEMLR might want matting in or adjacent to that area - perhaps Gary Novak can clarify. We also understand that no
upland seed mix can be used in the wetland area - if vegetative cover is needed for stabilization we will use an
appropriate wetland seed mix.

Subject: [EXTERNAL] RE: Windsor Solar Site
Importance: High
Good morning,
I've spoken this morning with Brian Smith at Carolina Ecosystems who will be doing the additional soils work at the
Windsor site. They propose using a hydraulic split -core sampler which is track -mounted to minimize soil disturbance.
He does not anticipate using the corer in the existing surface wetlands (which I believe is the area Kelly is addressing) - if
sampling is necessary in that area (e.g. to provide baseline profiles) it will be done using hand augers. If erosion control
matting is in place at any sampling location, it should be easy enough to clip a small hole, <6" diameter, to admit the soil
corer. Please let me know if the Corps or NCDEQ would like an alternative methodology.
Also, Tim Hayes is our Environmental Development Director in the Renewables group here. He will be leading the
process from our end to get satisfactory resolutions at both Windsor and Bethel. Please make sure Tim is copied on all
emails going forward.

Thanks,
Charlie

This week, SunEnergyl has been repairing and installing erosion control measures, applying lime and seed, and blowing

Thank you for the opportunity to address the matters presented in the Division of Water Resources'
February 22, 2017 Notice of Violation and Recommendation for Enforcement ("Notice"), issued to
both Duke Energy Renewables NC Solar, LLC ("DER") and SunEnergyl, LLC ("SEl" ). You may
also receive a separate response from SEL
As supported by the information presented below, our current knowledge of the timing of events and
DER's role in the Project, we believe that this NOV should not be directed to DER. However, in a
spirit of cooperation and desire to resolve this issue, we are responding to present the Plan of Action
requested by your Notice,
Our Plan provides the responsive information that is available to us at this time. We will provide a
more detailed response once we gather additional information, including specific information on field
conditions as they existed in 2013 prior to construction. We are working quickly on that point, and
DER has already been coordinating a proposed soil sampling plan with both your agency and the
United States Army Corps of Engineers (the "Corps"). The sampling plan is designed to evaluate, to
the extent practicable, the spatial extent of jurisdictional waters at the time of impact. Both agencies
have now concurred with the proposed methodology and we intend to commence the work soon.
With this as background, our Plan of Action consists of the following:
• Your paragraph 1: We are submitting our Plan within 15 days, as you requested. However,
please note that as of the date of this response, DER has not received written notification from
the U.S. Army Corps of Engineers of Section 404 violations.
• Your oaragraph 2: You asked (i) when construction began at the Project, and (ii) how impacts
occurred. Due to DER's limited role in the development and construction of this project, these
questions are best answered by SE I and hopefully their response to the NOV will help answer
them. However, based on DER records, on item (i), Windsor Cooper Hill Solar, LLC

("WCHS") (the DER affiliate that owns and operates the Project) issued a Notice to Proceed to
SEI on October 11, 2013, so we are aware that certain construction activities began on or after
that date. We are also informed that the Town of Windsor/County of Bertie may have been
responsible for some of the clearing and site grading work, but we do not yet know the timing
or scope of the Town's activities. We are also aware that clearing and grading activities at the
Project Site were completed on or around November 15, 2013. On item (ii), the results of our
upcoming fieldwork (and the time period while those activities are taking place) will allow
DER to evaluate not only the extent of jurisdictional waters, but also when and how the
impacts might have occurred. Among other things it will allow us to continue to coordinate
with SEl and better understand the nature and timing of activities in areas of concern. SEI
was the Engineering, Procurement and Construction ("EPC") firm for the Project, and was
solely responsible for site development, preparation, design and construction, among other
obligations. If necessary, we will prepare and submit a supplemental response to this
paragraph after we complete our investigation, fieldwork and evaluation.
Your aragraph 3: The investigation, fieldwork and further evaluation is especially important
to our response to paragraph 3 because neither DER nor WCHS directed, or intended for the
Project to involve, the discharge of fill materials into jurisdictional waters. In fact, DER
conducted and was aware of wetlands estimation and/or delineation activities at the Project.
Such activities were performed to ensure that the Project complied with applicable law. For
example, prior to site development DER retained a wetland consultant, Energy Renewal
Partners, which provided a conservative estimation of potential wetlands. That estimation was
subsequently used to produce the Erosion & Sedimentation Control Plans that were provided to
SEI.
In sum, neither WCHS nor DER believed that the Project required a Section 404 permit or a
Section 401 certification; if a violation of those requirements took place, it was not done by
DER or WCHS.
If necessary, we will prepare and submit a supplemental response to this paragraph after we
complete our investigation, fieldwork and evaluation.
• Your paragraph 4: As noted above, we have already coordinated a scope of work to evaluate
jurisdictional waters. We will notify both DWR and the Corps prior to the upcoming soil
investigations, should you wish to observe our work. We expect to complete that work by
April 30, 2017. We will then submit a technical report to DWR and the Corps by June 1, 2017,
which report will include the information that you requested in paragraph 4 of the Notice.
Your paragraph 5: After we submit our technical report we will coordinate with the agencies
on a final jurisdictional determination. Based on the agreed upon extent of final jurisdictional
waters, within 60 days, we will submit the Restoration Plan required by paragraph 5. Our
Restoration Plan will consist of either (i) applications for the appropriate Section 404 permit
and Section 401 certification, (ii) a restoration plan that complies with paragraph 5.b. of the
Notice, or (iii) a combination of the two if some, but not all, of the impacts will be removed
and remediated. To the extent that a restoration plan is proposed, that plan will commit to
complete the work by December 1, 2017, or a later date agreed to by the agencies.
• Your paragraph 6: DER is held to the same high standards of environmental compliance and
operational excellence of its parent company, Duke Energy Corporation. Since 2013, DER has
implemented a number of measures to ensure the projects we acquire meet or exceed all

Tom McNay
Vice President
Duke Energy Renewables NC Solar, LLC
550 South Caldwell Street, Suite 600
Charlotte, NC 28202
requirements of environmental laws, rules and regulations. These measures include the
development of environmental due diligence processes; procedures for the "hand-off' from
development to construction to operations; hiring of highly qualified environmental scientists
in Duke's Corporate Environmental Services group dedicated to DER's solar development; and
other similar measures. In response to this event, we are evaluating additional processes
devoted to environmental compliance, and in the meantime will review our level of oversight
of all EPC contractors to ensure that their work complies with environmental requirements.
We believe that with the staff, processes and procedures in place now and in the near future, we
will mitigate the risk of similar issues reoccurring in the future.
We believe it's important to note that DER discovered this issue and raised it to the attention of SEI,
who in turn notified DWR. This self -reporting further demonstrates DER's commitment to
environmental compliance and desire to resolve this issue.
Please let us know what other information you would like to receive about the proposed Plan of Action,
including whether you have any questions or concerns about the proposed timeline and responses.
DER values our relationship with DWR and will continue to work diligently to resolve this matter and
to ensure that the Project is brought into compliance with applicable requirements. This includes
ensuring that the Plan of Action outlined above is carried out as required.
Thank you for your consideration of our Plan. Please let us know if you have any questions or need
anything further from us along these lines.

Dear Mr. Tankard:
Thank you for speaking with me yesterday. As requested, I am writing to confirm that
our law firm has been engaged to assist SunEnergyl in responding to the Notice of Violation
("NOV") that was dated February 22, 2017, and received in our client's office on February 28,
2017, as well as to request a 30-day extension of the deadline to respond to the NOV. Since our
firm has only recently been contacted, I hope you can appreciate the need for us:
1) To assemble and review the background documents/emails (which are voluminous)
which will require assistance from the company's information technology ("IT") staff,
and;
2) To speak with the various individuals who were involved with the project.
We believe we will need this extension due to these previous steps, as well as the relative age of
the project; the volume of emails and related documents; and the number of employees at
Washington, D.C. Maryland New York Massachusetts New Jersey Texas California

BEVERIDGE & DIAMOND[IC
Mr. Robert Tankard

SunEnergyl who worked on the project (and the staff changes). We do believe that this
additional time will allow our client to provide a response which is both complete and accurate.
Based upon a review of the NOV, as well as a review of the response from Duke Energy,
our client believes that there may be some critical misunderstandings surrounding our client's
relative role and responsibilities in this project, which they intend to clarify (with support).
Accordingly, please confirm to me (by email) that your Office is willing to grant this 30-
day extension (until April 14, 2017). Please know that our client is taking this NOV very
seriously and is prioritizing this response. We welcome the opportunity to share our client's
perspective and to work towards reaching a mutually acceptable resolution of this dispute.

deadline is currently set for April 7, 2017. Accordingly, I am requesting a similar 30-day
extension so we can engage in the same review tasks necessary for my client to adequately
respond.

Jay I agree with your summary and after looking at the attached layout drawing it is almost exactly in line
with what we had estimated on Monday. Go ahead and plan on meeting with the surveyor as soon as
possible.
Bradley what this means to you is that based on the layout I had Monday and this drawing you have roughly
half the width of the project,site where the (blue line/wetlands is located on Track B) that you can reshape
and build as you like. Remember that you will need to maintain a ditch - drainage area for any flow coming
from the other half of the wetlands so that it can drain off of our site.
Talk with you later today.

Subject: Windsor solar tract B wetland area
Hello Steve, please review the attached wetland area map for Tract B. The hydric soils & vegetation were
very evident in the northern end of the wetland feature. However, the hydrology was lacking. I drilled
several holes, some down to 30" and never hit saturated soils. The Fac- test is definitely there but did not see
any other primary or secondary wetland hydrology factors. Spagnum moss was also thick in some areas but
was concentrated in what appeared to be old tire track areas. This was likely due to the log skidders
crisscrossing this area since the staging area was immediately to the west of this bowl -shaped area.
Therefore, I recommend the following. Have the surveyor acquire flags AA 1 to 7 & BB 1 to 7. The current
map was done with a hand-held garmin gps. I also tied a pink wetland boundary flag just beyond flags AA &
BB 7. The lower part of the identified area will be the hydrological connection to the lower dirt road culvert
& eventually Cashie River. The middle & lower areas were dominated by sweetgum & especially loblolly
pines. Both of which are more indicative of non -wetlands compared to the more prevalent maples up top.
Though there's a decent slope in the lower section, no drainage patterns, wrack lines, etc. were evident and
the pine straw was thick & relatively undisturbed.
This should give Bradley some flexibility to continue the rows across this entire drainage area, especially the
middle & lower rows. The lower site could be graded provided he maintains the hydrological connection,
which he will since he needs this drainageway. As William told us Monday, he could drive pilings throughout.
Since it's mostly grass, rush, & sedge plants with some saplings, mowing in there should be fairly simple.
Though the photo is not the greatest due to the early morning sun, it gives a representation of what the
upper area looks like. I could meet the surveyor this Friday at 2 or after. Tuesday early morning or late
afternoon is possible too. We have some site assessments scheduled down there Tuesday. Hope this helps &
feel free to contact me for discussion. Thanks, Jay

As you know, our law firm represents SunEnergyl, LLC ("SEl") in this matter, and on
behalf of our client, we thank you for extending the deadline for response to the Notice of
Violation and Recommendation for Enforcement dated February 22, 2017 (the "NOV") that was
issued to Duke Energy Renewables NC Solar, LLC ("DER") and SEL Because the events in
question occurred in the fall of 2013, SE1 has taken reasonable measures to gather and review
related documents and emails, as well as speak with personnel to better recall the underlying
facts involving the grading activities and responsibilities at the Windsor Solar Project. In
addition, SEl remains willing to review any additional documents or related information in the
possession of the North Carolina Department of Environmental Quality ("NCDEQ") (formerly
Department of Environment and Natural Resources ("DENR")).
This project took place in phases, and involved a number of different parties who
assumed different responsibilities. Accordingly, before addressing the requested responses, we
are providing a short description of the parties and the relevant construction chronology as
ascertained from review of SE1 records.

BEVERIDGE & DIAMOND1K.
Page 2
Relevant Parties and Responsibilities for the Windsor Solar Project:
The Town of Windsor ("the Town") is the landowner of the subject property where
the Windsor Solar Project is located. The Town proposed the site location to DER
and executed a Ground Lease and Easement Agreement (the "Ground Lease") with
DER's affiliated project entity, Windsor Cooper Hill Solar, LLC, ("WCHS") -
effective October 24, 2013. The Town also selected the construction company,
Phelps & White ("P&W"), who cleared and graded the land for the project. The
contract work for clearing and grading the land was credited by the Town against the
DER Ground Lease.
WCHS is the tenant for the site under the Ground Lease with the Town. DER applied
for, and received approval of, the Erosion and Sedimentation Control Plan
("B&SCP") for the Windsor Solar Project. Under the Ground Lease, DER was
responsible for the clearing and grading of the property. Based upon its experience,
DER also took the lead (on behalf of WCHS) and hired/directed the following
subcontractors/consultants in various site -related activities, including wetlands
delineation:
Energy Renewable Partners ("ERP") — pre -construction wetlands
delineation.
Keller Environmental - wetlands delineation.
American Engineering ("AE") - civil engineering and Erosion and
Sediment Control Plan.
• SEl was the Engineering, Procurement and Construction ("EPC") firm for this
project, and was tasked with the construction of the solar facility.
Chronology of the Windsor Solar Project (Based on a Review of Available Records):
9/4/13 The Town introduced Bill Long (SEI) and Tim Phelps (P&W) to
the site.
9/5/13 Andy Cranfill (DER) submitted a boundary survey to SEL
9/18/13 Steve Rutledge (DER) coordinated with DENR regarding E&SCP
permitting with Lauren Sicarellis (ERP) regarding survey, CADD
files, layouts, topographic maps, etc.
10/11/13 WCHS issued a Notice to Proceed to SE I, pursuant to the EPC
Agreement.
10/15/13 Andy Cranfill (DER) discussed E&SCP permitting with
Allison Ward (DENR).

BEVERIDGE & DIAMONDI,
Page 3
10/21/13 Steve Rutledge (DER) contacted Bradley Fite (SE I) and asked
whether the Town had obtained an E&SCP permit. Steve Rutledge
(DER) indicated that trees could be harvested but no grubbing,
stump removal or grading could be performed.
10/24/13 The Ground Lease becomes effective. As provided by the Town,
P&W began site clearing on Tract A.
10/28/13 Andy Cranfill (DER) contacted Bradley Fite (SEI) and David
Harris (SEl) via email regarding the panel layout for Tract B,
which appeared to be outside the property boundary. Lauren
Sicarellis (ERP) needed the new layout to submit to DENR.
10/29/13 An Express Review meeting was held with DENR regarding
E&SCP and stormwater permitting. During this meeting, DENR
gave feedback and direction, which included, among other items:
Granting permission to contour some land.
Requesting a revised site layout, since the first version
was incorrect in that the E&SCP site boundary had
extended beyond the project parcel. Scott Stone (AE)
was tasked to submit a revised layout.
10/31/13 Andy Cranfill (DER) contacted Brian Kennedy (DER), Kenny
Habul and Bradley Fite (SEl) via email to discuss revised
drawings and the re -cutting of the two western ditches. Scott
Stone (AE) indicated that cutting the ditches would cause some
problems due to off -site properties. Plus, Stone had only heard of
the ditch change on 10/30/13.
10/31/13 Allen Castelloe (the Town) notifies Bill Long (SE1) that the
Town had received an invoice from Tim Phelps (P&W) for the tree
clearing.
11/1/13 Scott Stone (AE) notified Bradley Fite (SEl), Kenny Habul (SE I),
Andy Cranfill (DER), Lauren Sicarelli (ERP), James McRacken
and Brian Kennedy (DER) via email that Pat McClain (NCDENR)
had contacted Scott, informing him that the E&SCP Permit was
approved. Stone's email states:
"His approval assumes that he will receive the two revised
sheets which show the new panel layout for Tract B. We
still need guidance on the recent panel layout as there are
still panels shown in a recorded easement on Tract B. "

BEVERIDGE & DIAMONDn:
Page 4
11/6/13 Jay Keller (Keller Environmental) contacts Steve Rutledge (DER)
stating that the middle and the lower section of the previously
identified wetland by ERP was more indicative of non -wetlands.
In particular, Keller advised:
"This should give Bradley some flexibility to continue
rows across the entire drainage area, especially the middle
and lower rows. The lower site could be graded provided
he maintains the hydrological connection, which he will
since he needs this drainage way. As William told us
Monday, he could drive pilings throughout. "
For completeness, the entire email is included as Attachment A.
11/7/13 Steve Rutledge (DER) responded to Jay Keller (Keller
Environmental) and agreed with his summary. He directed Keller
to meet with his surveyor as soon as possible. Rutledge (DER)
also included Bradley Fite (SEl) on the same email with an
attached drawing (see Attachment B), which showed the wetland
extending only to the middle of the original delineation. Rutledge
(DER) specifically instructed Fite (SEI) that:
"You have roughly half the width of the project site where
(blue line/wetlands is located on Track B) that you can
reshape and build as you like. Remember that you will
need to maintain a ditch -drainage area for any flow
coming from the other half of the wetlands so that it can
drain off our site. "
11/12/13 Shane Batchelder (SEI) informs Kenny Habul (SEI) that 70% of
Tract B had been cleared only and had not been contoured.
11/14/13 Andy Cranfill (DER) emails the construction/clearing invoice from
Phelps & White to Kenny Habul (SE1). The final invoice was
submitted on 1/7/14.
12/31/13 Project construction completed.
9/27/16 NCDEQ — Division of Mitigation Services ("DMS") approves
compensatory mitigation for jurisdictional waters impact.
12/8/16 CEI submits application to USACE and DWR regarding after -the -
fact Pre -Construction Notice for a Clean Water Act Section 404
Nationwide Permit 39, and Clean Water Act Section 401
certification.

BEVERIDGE & DIAMONDIX:

With this summary of parties and the timeline of the project in mind, below are responses
to the specific questions set forth in the NOV.
REQUESTED RESPONSE 1: Plan of Action
On February 16, 2017, SE1 met with representatives of the U.S. Army Corps of
Engineers ("USACE") and N.C. Department of Environmental Quality, Division of
Water Resources ("NCDWR") and Division of Energy, Mining, and Land Resources
("DEMLR"). DER, CEI, and Keller Environmental also attended the meeting. Contrary
to the prior expert conclusions reached by DER's wetland delineation experts, the
regulatory agencies and environmental consultants now allege that there may be an
indeterminate area that met wetland criteria, and that this area may have been disturbed,
graded and solar arrays installed in this location.
SEl is aware of DER's response regarding the proposed and approved sampling plan to
further delineate the wetland boundary and the extent of impact due to the installation of
solar panels, associated infrastructure, and earthen fill. SEl is currently coordinating
with DER and Carolina Ecosystems, Inc. ("CEI") to complete this plan and is willing to
continue to work with DER to take appropriate corrective action if necessary.
REQUESTED RESPONSE 2: Construction Chronology & Impact Explanation
The above chronology provides a detailed explanation of pre -construction and
construction activities at the site. In sum, based upon document review and
conversations with personnel involved with the project, the actual earthwork
construction activities began at the site in late October 2013 and continued through
November 2013. As previously noted, the clearing and grading was performed by
P&W. More specifically, based upon a summary of tasks contained within the P&W
invoice, it appears the clearing occurred between October 24, 2013 and November 13,
2013. SEl was aware that the equipment arrived on site in early November with the
solar panels being installed in December 2013.
As indicated in DENR's approved E&SCP (dated November 1, 2013), jurisdictional
waters were delineated in the southern Tract B field, and this area was not to be disturbed
per the approved plan. However, since the E&SCP permit was issued to DER and was
under their control, SEl reasonably expected that DER would submit revised plans to
DENR upon DER's determination that the lower portion of the wetland in Tract B was in
fact available for construction. As previously noted in the chronology, Steve Rutledge
(DER) informed SE and directed them to install posts throughout.

BEVERIDGE & DIAMONDrc
Page 6
REQUESTED RESPONSE 3: 401 Water Ouality Certification and 404 Permit.
SEI did not coordinate nor manage the wetland delineation or permitting processes.
DER took on this responsibility and hired two wetlands delineation consultants, and
managed the boundary and topography surveys, which were used in conjunction with
ERP's wetland determination to generate an E&SCP.
As noted in their response to the NOV, DER did not believe that the project required a
Section 404 permit or Section 401 certification. It is also important to note that
throughout this process, and at all phases of the project, each of the various parties
maintained open communication with representatives from NCDEQ, including Pat
McClain, who visited the site regularly.
REQUESTED RESPONSE 4: Wetland Delineation.
SEI understands that DER and CEI are performing an approved scope of work to further
delineate the referenced jurisdictional waters, with on -site work conducted the week of
April 3, 2017. SEI's engineering and construction team is willing to assist in any
continued site investigation.
REQUESTED RESPONSE 5: Restoration Plan
SEI understands that DER and CEI will submit a delineation report to DWR and
USACE, who will make a final and agreed upon spatial extant and wetland
determination. SEI is willing to coordinate with DER and CEI in their planned efforts to
submit a Restoration Plan, and, based on the final determinations, SEI will work
collaboratively with DER to mitigate the wetland impact.
REQUESTED RESPONSE 6: Preventive Planning and Implementation
Although this project did not involve SEI permits, the company has always been
committed to continually improving its environmental compliance standards and due
diligence processes. Recently, SEI has augmented our professional environmental staff
with personnel from the environmental consultant industry. By augmenting staff as well
as implementing an improved internal process to review critical wetlands issues, SEI is
well -positioned to fully comply with all the requirements of federal, state, and local
environmental regulations.

BEVERIDGE &DIAMONDIK:
Page 7
CONCLUSION:
SEl is continuing to work with DER on wetland delineation, and if impacts are
identified, SE is willing to assist with remedial efforts.
Please let us know if there is additional information we can provide to ensure a complete
understanding of our Action Plan and the contingent evaluations anticipated for a future
mitigation plan. Thank you again for granting SEl an extension of time to respond to this Notice
of Violation and Recommendation for Enforcement Notice.

Subject: Duke Energy Renewables Windsor Solar Site
Mr. Scarbraugh and Barnes: This past Monday, May 15 you received a proposal from Duke Energy Renewables to
resolve alleged wetlands/waters non-compliance issues at the Windsor Solar site located in Bertie County, NC.
It is Duke's desire to resolve this issue expeditiously and would prefer to execute the agreed upon restoration activity
during the upcoming dry summer conditions. With this in mind to keep us on schedule, would you all be available to
meet with us via conference call next Wednesday or Thursday to discuss our proposal? Let me know which day (if any)
works best for you and the times you are (or aren't) available and I will send out a meeting notice with up a conference
call number.
Thanks and have a good weekend.

Kyle and Anthony, In preparation of our call on Friday morning, I wanted to get you our proposed conceptual plan for
impact/restoration of wetlands/waters at the Windsor solar site. These are preliminary and conceptual in nature, but
incorporate the feedback we received from you on our last conference call. It will also give us a reference to talk from
during our discussion on Friday.
Also, (hopefully) you will be seeing a separate e-mail from me (due to file size) here in minute with a detailed restoration
plan prepared by Brian Smith at Carolina Ecosystems. It's a large file (17 MB) so I hope it goes through. If you do not see
a second e-mail from me on Bethel, let me know and we will strip out the photos to reduce the file size.
Thanks and we look forward to discussing these with you on Friday morning.

meeting request re Windsor solar
Good afternoon,
We'd like to set up a meeting at your Washington offices for some time during the week of August 7 —11 to discuss the
Windsor solar site. Per the concerns raised during the last call, we are refining the proposed resolution - including
additional modeling of the overland flow which incorporates the new existing -conditions survey, and preparation of a
draft PCN detailing avoidance and minimization measures. We will provide you with those materials at least 2 days prior
to the meeting; most of these can be delivered via email but we can also postal mail full-size plats if necessary.
The removal of the panels at Bethel solar site is underway and is about 15% completed. The panels and torque rods are
being removed by hand with the only vehicular access occurring along the N-S sewer easement in order to expedite
moving the panels out of the restoration zone. Duke Energy staff were onsite yesterday and we are satisfied that no
undue ground disturbance is taking place. We anticipate all the panels will be out within another 10 -15 working days,
weather permitting. The E&SC plan from NC-DEMLR is still pending but we will ensure that it is in hand and all BMPs in
place prior to any heavy equipment entering the restoration area to remove the pilings. That removal is anticipated to
take as long as 6 - 8 weeks and Duke Energy staff will be onsite to monitor and stop work if necessary due to soil
wetness conditions.
Please advise me of your availability for the proposed meeting and we will adjust schedules here accordingly.
Thanks,
Charlie

Impact Justification and Mitigation
1.
Avoidance and Minimization
la.
Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
In consultation with USACE and as referenced in Section B. 4..a. above, the jurisdictional extent of wetlands on the
project site was derived from a combination of a September 2016 field review and the results of a May 2017 soil boring
investigation, as given in Figure A and the co -submitted Jurisdictional Determination Request. Total jurisdictional
wetlands on the Project site are 0.90 acres.
The Applicant is proposing to permit, after the fact, 0.39 acres of wetlands under NWP 39. In requesting this amount of
impact, the Applicant evaluated the Project layout in light of (i) the jurisdictional waters, (ii) the technical needs of a viable
solar project (which include maintaining practicable and effective vehicle traffic and electrical and mechanical connectivity
across the Project site), (iii) avoiding and minimizing permitted impacts by ensuring that the minimum amount of wetland
impacts (as necessary to maintain access and connectivity) remain after restoration, and (iv) ensuring that wetland
impacts are reduced to below the 0.5 acre threshold in NWP 39. With these factors in mind, the 0.39 acres of proposed
impact includes two areas. First, the Applicant proposes to retain and permit 0.37 acres of impact in the feature at Wt,
which bisects the site. As shown on Figure A, that impacted area extends from the access area along the southwestern
perimeter of the Project site to just above the northernmost internal access corridor across the site. Retaining these
impacts will allow the necessary access and connectivity and avoid isolating the eastern portion of the Project — absent
preserving these access points, maintaining the electrical and mechanical connectivity of the Tract B solar arrays would
prove very challenging from an engineering standpoint. The Applicant proposes to remove approximately 300 solar
panels (and associated equipment) from the uppermost 0.38 acres of that feature and then restore and enhance that
area. The Applicant will also create a surface drainage way along the 0.37 acres of impacted waters that will convey
overflow water between and under solar arrays to the south of the Project site. This created drainage way will be
providing a similar water conveyance function as the original wetland drainage feature that was filled.
As regards Impact W2 and the southeastern corner, this wetland feature was discovered during the 2017 soil boring
investigation. The Applicant now proposes leaving the small area (0.02 acre impacted) as is in order to allow continued
vehicle access along the fenced perimeter. The larger impacted area (0.10 acre restored) outside the fence abutting the
floodplain will be excavated and restored. An additional 0.03 acres of undisturbed wetlands will remain undisturbed.
b.
Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
The details of the restoration plan are supplied as a supplement or appendix to this application. In summary, the
northern area will have the solar panels removed by hand within the restoration area. Extraction of the pilings will be
done using tracked or wide -tire equipment. In areas where wetland vegetation is not currently established, any remaining
fill will be removed and replaced with organic soil suitable for re-establishment of wetland vegetation. Planting density,
species selection, and annual monitoring will then be conducted to meet DWR mitigation specifications. A low berm and
water control structure will be employed to maintain adequate hydrology and the engineering specifications for the
surface drainageway submitted for USACE/DWR review. The southeastern corner will be excavated to pre -construction
contours to restore floodplain connectivity and replanted as given above.
2.

Windsor Cooper Hills Solar Farm
Tract B Drainage System Narrative
Tract B of the Windsor Cooper Hill Solar Farm is located south of the Bertie Correctional Facility.
The site generally slopes from north to the south. Predeveloped LiDAR data indicates elevations
along the north site boundary ranging between 20 and 28 feet above mean sea level with the
south side ranging between 22 and 8 feet above mean sea level. The property was wooded prior
to development as a solar farm in 2013. This development included grading although drainage
patterns were generally maintained. In 2017, Duke Energy Renewables requested Albemarle &
Associates to assist with drainage and erosion control issues associated with proposed wetland
restoration efforts. This scope includes two areas within Tract B referred to as WA and WC.
Wetland Restoration Area WA
Wetland restoration area WA is located on the north edge of Tract B. Runoff from the north is
conveyed onto the project area and is directed through the site to the east within a natural swale.
The construction of the solar farm maintained this drainage pattern, although the site was cleared
and grading was performed which did result in modifications to the elevations in addition to altered
ground cover. The current drainage pattern from the wetland mitigation area meanders through
the solar arrays to the south and is directed into a 24" culvert which conveys runoff beneath the
gravel driveway and onto a rip -rap apron south of the site. Ultimately runoff flows into a
wetland/swamp area prior to being discharged into the Cashie River (stream classification C, Sw,
stream index 24-2-(1)). The drainage route between the wetland restoration area and the outfall
culvert was not graded as a defined channel and crosses arrays and access aisles at random. In
addition, the land is currently not stabilized very well in portions of this drainage way. This
combination has resulted in erosion along the southern half of the drainage way. This has been
further exacerbated by service vehicles rutting the access paths creating random and changing
points of concentrated flow as well as the effects of support pilings incurring additional erosion
issues.
It is desirable to establish a defined and protected drainage way for runoff to cross Tract B. The
project has low -density stormwater management permit that precludes this runoff from being
conveyed in a discrete (closed / underground) system, so an open swale system is deemed
necessary. The intent of the engineered swale system is to create a defined drainage way
between the solar arrays to reduce the potential for erosion at support posts and maintain access
for mowing and other maintenance. The location of the swale system follows the general route of
the existing drainage way in order to limit land disturbance and required grading. The swale
system utilizes culverts at drive access aisles to eliminate the potential for rutting to disrupt
drainage system at these locations as well as to shift the swale system west to align with existing
topographic conditions.
LiDAR data was utilized to establish overall drainage patterns within the areas to determine the
size of the drainage area that contributes to the system and for the preliminary design of the
drainage system. With this data it was determined that approximately 13.68 acres from the north
and east is directed into the wetland restoration area WA. Most of this area is off -site & wooded
and the soil type is defined as Leaf Loam (Lf) and Craven Fine Sandy Loam (1 % to 4% - CrB).
The soils map in included within this report (Figure 1). As the swale system proceeds south from
WA, additional drainage area (mostly from within the site) contributes to the system. These areas
have been broken down at each drive access aisle/culvert, with the upstream drainage area

referred to as "Area 5' and the lowest/last additional downstream drainage area referred to a
"Area 1". This is illustrated in the map in this report (Figure 2) and summarized in the table below.

Topographic survey data of the drainage system project area was obtained by JH Miller Jr. Land
Surveying and utilized for the final design of the drainage system. A 24-hour extended dynamic
model was created for the drainage system using EPA SWMM to calculate the discharge values
at each of the reaches noted above as well the corresponding depth and velocity of the flow within
the swales and culverts. Figures 3 & 4 illustrate the segments (swales & culverts) in plan view
and the corresponding modeling links. The dynamic modeling analyzes the drainage
characteristics within the system and reports the flow, depth and velocity for each link (swale
and/or culvert). These values are reported at 10-minute increments throughout the duration of the
24-hour event system and account for attenuation. Tables 1 through 4 include the peak flow,
depth and velocity of the 10-year (5.73 inches) and 50-year (8.51 inches) rainfall events. The
tables below includes the maximum flow, depth and velocities for each section of swale within the
10-year and 50-year rainfall event.

As shown in in Figures 17 & 18, the accepted maximum permissible velocity for vegetative lined
channels (grass mixture) on soils with a K value less than 0.37 is 5.0 ft/sec. The maximum velocity
within the swale system is calculated to be 3.49 ft/sec for the 10-year rainfall event and 3.99 ft/sec
for the 50-year rainfall event which is well below this accepted value for vegetated channels.
However, the accepted maximum velocity for unvegetated channels (prior to the establishment of
permanent vegetation) is 2.0 ft sec. To address this issue, a Rolled Erosion Control Product
(RECP) with a permissible channel velocity of at least 5 ft/sec will be utilized to maintain stability
within the channel and hold seeding in place until permanent vegetation is achieved. The selected
minimum liner maintains compliance with this condition (see Figure 19). Figure 20 also includes
permissible shear stress for the RECP which complies with the calculated values below. Appendix
A contains the figures and analysis summary tables for this drainage system associated with the
restoration area "WA".
Wetland Restoration Area WC
Wetland restoration area WC is located near the southeast corner of Tract B and receives runoff
from a combination of on -site land on the southeast corner of Tract B as well as and off -site land
to the east for a total drainage area of approximately 4.1 acres (see Figure 5). The area referred
to as WC was filled during construction and stabilized with a rip -rap armored slope that conveys
the runoff from the site to the swamp area to the south. This area will be excavated to restore
wetlands and a 3(H):1(V) slope will be established from the toe of the restoration area back up to
the existing grade.
Topographic conditions will continue the direct runoff to this portion of the site. To accommodate
this runoff, a "diversion swale" will intercept the runoff that would otherwise be directed to the re-
established slope (approximately 0.9 acres) and convey the runoff to the east. A culvert (referred
to as "diversion swale culvert") will be installed to collect runoff from the "diversion swale" plus the
terrain to the north and east (total drainage area approximately 4.1 acres) and convey it beneath
the fence. The culvert will discharge into a swale (referred to as "ouffall swale") which will convey
the runoff to a newly established rip -rap flume that will provide an armored path to direct runoff
down the slope and onto an rip -rap pad below to dissipate energy at the toe of the slope. These
elements are shown and labeled on Figure 6. A second rip -rap flume will be installed on the west
side of WC to collect and convey and runoff from the small drainage area in the immediate vicinity.
Because this drainage system is much smaller, Hydroflow software was used to develop
hydrographs for the "diversion swale" and "diversion swale culvert" and "outfall swale" for the 10-
year/24-hour and 50-year/24-hour rainfall events. These hydrographs are in the "Hydrology
Reports" contained in Appendix B. The resulting swale and culvert depths and velocities resulting
from these peak discharge values were then analyzed in the "Channel Reports" and "Culvert
Reports" that are also contained in Appendix B. The tables below includes the maximum flow,
depth and velocities for each section of swale within the 10-year and 50-year rainfall event.

Finally, it is important to note that the tractive force, or shear stress in a channel
does not remain constant across the entire channel. Figure 3-6 shows how the shear
stress changes across a trapezoidal channel. The important thing to keep in mind is that
shear stress is almost always maximum at the point in the channel where the depth of
flow is the greatest.

Good morning guys. I wanted to drop you a note and let you know that we are still reviewing the soils investigation
report for the Windsor solar project. As such, we need a little more time to complete our review of it. Note that we
committed to having this report to you by June 1 in our NOV response - however, it will likely be before this date. We'll
get it to you all as soon as we can. Let me know if you have any concerns or questions. Thanks and have a good

Good Morning,
We have had difficulty procuring the Swamp Chestnut Oak as restorative species for the Windsor Site. Allegedly, the
nurseries do not carry this species due to its low success rates and lack of demand. We would like to swap out this tree
with the Swamp White Oak which is more readily available with higher success rates.
Please let us know if this allowable at your earliest convenience.
Thanks,

Re: Notice of Violation of Sedimentation Pollution Control Act
and General Permit — NCG 010000
Windsor Solar Project
Project ID: Bertie-2014-003
Bertie County
Dear Mr. Dumpor:
This letter serves as a follow up to our telephone conversation of March 29, 2017
between Mr. Richard Peed, you and me concerning Duke Energy Renewables NC Solar,
LLC's ("DER") response to the noted NOV related to the Sedimentation Pollution Control Act
and the construction stormwater general permit -- NCGO10000 for the Windsor Solar Project.
During our discussion you requested a number of revisions and additional information related
to our original submittal. The following are in response to your requests:
1. The Forested Tracts. In our original response, DER stated our position that
while the timber removal activities may have been conducted for the benefit of the solar
facility, `land disturbing activities" as defined by the SPCA did not occur on the Forested
Tracts. We understand your interpretation of this activity based upon our recent conversation.
While we maintain our position that this timber removal work should not be considered a
"land disturbing activity", we are complying with your request to provide an expansion of the
original project site plan to include the Forested Tracts where trees were removed. Please find
enclosed the following:
a. A check for the amount of $ 520.00 to cover the application fee for
plan reviews of the expanded site. The additional Forested Tracts add
to approximately 7.56 acres. Rounding to the higher number of 8 acres
x $ 65/acre fee = $ 520.00
b. Landowner letters and email correspondence submitted as evidence of
approvals and knowledge of the timbering activity performed on their
land. There were five tracts of land located on four separate parcels of
land. Each parcel has separate land owners. Attachment A includes

the correspondence with these land owners. The work is now
complete on these tracts of land.
2. E&SC Plan Revisions DER previously submitted a revised set of Erosion and
Sediment Control plan drawings that showed the Forested Tracts, as well as current erosion
control and best management practice measures that are now in place to stabilize the site.
During our recent call we discussed several areas where the plans could be improved to better
show the current conditions and applied measures. Enclosed are three (3) copies of anew
revision to these plans to include the following changes:
a. The potential "wetland" area that was defined in the original E&SC
plans is shown in Tract B and noted as an area still being evaluated.
b. The Forested Tracts that were shown only on the first sheet of the
overall plan in the last revision are now shown on all three sheets
comprising the E&SC plan.
c. All matting and other BMP measures that have been installed on the
site are now shown on the drawings to be as complete as practical and
to show the extensive work that has now been performed to stabilize
the site.
d. In addition to the BMP measures, grass seed has also been sown in the
areas outside of the potential "wetland" area to stabilize the site. In
our discussion it was suggested that we might also include a history of
the work that has been done previously in an attempt to establish
vegetation growth at the site. The following is a historical timeline of
those efforts as provided by our EPC Contractor Sunenergyl, LLC (SE1):
• Spring 2014 — SE1 seeded the site and fertilized with rate of 10-
10-10: 300 Ibs / acre. Lime application was not performed
• Fall 2014—SEI's contractor, JED landscaping, applied lime at
the rate of 1000lbs/acre
• Spring 2015 —JED landscaping reseeded area
• Fall 2015 —JED Landscaping applied lime at the rate of 1000
Ibs/acre
• Spring 2016 — JED landscaping reseeded area
• Spring 2017, 2/16-2/24/17 & 3/21/17: SE1 applied lime at the
rate of 600 Ibs/acre, reseeded, installed straw mulch, and
repaired and installed additional erosion control measures,
including silt fences, check dams, and geotextile fabric.
3. Site Insnection — As you had indicated, a Site Inspection was conducted by Mr.
Gary Novak from your office on April 5, 2017. Mr. Novak was met and accompanied by
representatives from both DER and SEl. The Site was walked and inspected to review the
measures that have been put into place, as well as to note any additional areas which may need
attention. Personnel were available to address any areas in need of further attention. This
work was performed immediately and pictures were emailed later to Mr. Novak to verify its
completion. Our representatives believed that Mr. Novak was satisfied with the work that has

been conducted and the progress at the Site in accordance with the E&SC plan. In addition,
the storage of Self Inspection reports and rain gauge logs were reviewed onsite. DER has
installed a weather station onsite that transmits data such as rainfall to a webserver. This was
done to facilitate the needs for monitoring Sites such as Windsor Solar where there are not
regularly personnel at the Sites on a daily basis.
We hope that our actions continue to show that DER and Windsor Cooper Hill Solar,
LLC have taken this matter seriously, worked to address the Division's concerns, acted
quickly to respond to and correct concerns and implemented actions to prevent a recurrence of
the alleged violations. Accordingly, DER respectfully reiterates our requests that no civil
penalties be directed to DER/WCHS in connection with the Notice.
Sincerely,
Tom McNay

Good Morning Mr. Powell,
I just wanted to update the status of the timber removal project at your property adjacent to the Windsor,
NC Solar Plant. We have completed the work on your property per our agreement. Fortunately, we we're
able to remove most of the felled timber rather than leaving it on site as originally agreed. This of course
leaves your property in a better esthetic and usable condition (rather than felled timber strewn about). The
temporary safety fence will be replaced with permanent fence over the next two business days.
Thanks again to you and your family for allowing SunEnergyl to resolve our tree shading performance issues
This work will prompt a final performance test for Duke and Dominion Power and the Town of Windsor.
Have a great week!

Good Afternoon Mr. Powell,
SunEnergyl has received all of the adjacent land owners approval to resolve our tree shading issues at the
Windsor Solar Facility. The NCDPS gave us their permission yesterday. We have contracted with a regional
timber company to remove the agreed areas. They are mobilizing today and commencing work tomorrow;
Friday at the rear solar field West side property. We expect to get to your property within several days. I have
arranged for seven fence panels to be removed at the North Solar Array field which allows the access we

need to fell the timber on your property per our agreement. Temporary fence will be installed as we
complete the work each day. Once the project is complete the permanent fence will be reinstalled.
Thanks again for your support and assistance in helping SunEnergyl to resolve the shading performance
issues for Duke/Dominion Power and the Town of Windsor.

Gentlemen,
Good Morningl 1 assume each'of you have received payments this week for the value of trees at your
property in Windsor, NC.
Thanks again to each of you allowing SunEnergyl to remove the 100' swath of trees adjacent to our solar site
in Windsor. The logging company: Coastal Plain Timber Co. has mobilized this morning and may start work
today; weather pending. The owner's name is Hugh Kennedy. Eddie Vanderford has marked the agreed area
to be removed. They are fully aware of the hunting stands and other equipment and will protect them. They
are also aware of the taped trees that are to be protected; unless as agreed, cast shadows towards the solar
panels and will also be removed.
The State of NC has granted written permission to utilize the roadway around Bertie Correctional to Cooper
Hill Rd. Bert!e Correctional's Superintendent and the Manager of the Town of Windsor have also been
notified of our entire maintenance operation.
Thanks again for your assistance in helping to resolve the non-performance issues for Duke/ Dominion Power
and the Town of Windsor. Have a great day!
