RE: Tar -Pamlico Buffer Authorization Request
Conetoe II Solar; Wetland Swale Conveyance Ditch
Conetoe, Edgecombe County, North Carolina
Project #: 36844
Dear Mrs. Higgins:
P 919.866.4951
F 919.859.5663
www.bnwnonro.com
On behalf of the Sunenergy1, Timmons Group is submitting a Tar -Pamlico Buffer Authorization Request
associated with the proposed construction of wetland swale conveyance ditches at the Conetoe II Solar
project site. The Conetoe II Solar project site is an existing solar panel farm located approximately 0.5
miles east of the intersection of Ellis Road and NC HWY 42 in Conetoe, North Carolina within Edgecombe
County. Currently, the solar panel farm is experiencing severe flooding which is a safety concern issue.
The purpose of the proposed wetland swale conveyance ditches is to convey existing flood waters from the
solar panel farm area into Knights Canal and Mitchell Swamp Canal. The wetland conveyance ditches are
proposed to control nitrogen and attenuate flow before the conveyance discharges through the riparian
buffer and discharges into the receiving stream. Please find enclosed for your review the following items:

PROJECT HISTORY & EXISTING CONDITIONS:
The project site is located approximately 0.5 miles east of the intersection of Ellis Road and NC HWY 42 in
Conetoe, North Carolina within Edgecombe County. The site was formerly an agricultural field and currently
consists of a solar panel farm. Wetlands and streams have been delineated by Keller Environmental. There
are approximately 20,000 linear feet of perennial stream located within the project site. A Tar -Pamlico
Riparian Area Buffer Determination was issued on November 14, 2014 (DWQ EXP# 14-1188, attached).
An on-site jurisdictional determination was conducted by the USACE (Craig Brown, USACE representative)
on May 5, 2015 with Keller Environmental (not attached).

PROPOSED PROJECT:
Currently, the solar panel farm is experiencing severe flooding which is a safety concern issue. The purpose
of the proposed wetland swale conveyance ditches is to convey existing flood waters from the solar panel
farm area into Knights Canal and Mitchell Swamp Canal. Wetland swale conveyance ditches are proposed
to control nitrogen and attenuate flow before the conveyance discharges through the riparian buffer. As
the conveyance system enters the riparian buffer, a culvert will be trenched and backfilled through riparian
buffer and discharge into the receiving stream. This is an effort to provide structural stability at the
confluence of the conveyance system and the receiving stream. Temporary and permanent seeding will be
applied to the impacted riparian buffer area.

AVOIDANCE & MINIMIZATION:
Allowing flooded conditions within the solar panel farm area to continue poses a safety hazard concern;
and therefore, avoidance is not an option. Traditional earthen ditch and/or rip -rap lined ditch options were
examined; however, neither of these options bests controls nitrogen and/or attenuates flow through the
riparian buffer. It was determined that constructing a conveyance system in the form of wetland swale
conveyance ditches through the riparian buffer would control nitrogen and attenuate flow the best.
Measures will be taken to prevent oil, tar, trash, debris and other pollutants from entering the adjacent
jurisdictional streams and buffers. Any excess excavated materials not utilized as back fill will be placed
and contained within upland areas and permanently stabilized to prevent erosion into adjacent jurisdictional
streams. Stockpiling of excavated material within jurisdictional streams will be strictly prohibited as part of
the construction of this project. Proper sedimentation and erosion control methods will be utilized during
all phases of construction and installation. The contractor shall install silt fence only as necessary to install
devices. All erosion and sediment control measures will be checked for stability and operation following
every runoff producing rainfall, but in no case less than once every week. Any needed repairs will be made
immediately to maintain all measures designed. An erosion control inspections report will be kept by the
owner's representative. Temporary seeding and permanent seeding plans are included to restore impacted
areas. The project will meet all relative requirements of Best Management Practices and Engineered
Stormwater Control Structures as outlined through the State Stormwater Rules.
MITIGATION:
All proposed stream buffer impacts are considered an Allowable Use within the stream buffer in accordance
with 15A NCAC 02B .0259 Tar -Pamlico River Basin; and therefore, mitigation is not required nor is it
proposed at this time.
SUMMARY:
The proposed construction of wetland swale conveyance ditches at the Conetoe II Solar project site is
required to alleviate existing flooding conditions within the solar panel farm area. The wetland swale
conveyance ditches will control nitrogen and attenuate flow before the conveyance discharges through the
riparian buffer and into Knights Canal and Mitchell Swamp Canal. As a result, there are proposed stream
buffer impacts which are considered an Allowable Use within the stream buffer in accordance with 15A
NCAC 026 .0259 Tar -Pamlico River Basin; and therefore, mitigation is not required nor is it proposed at
this time. The proposed project is a single and complete project with appropriate land use control and
stormwater measures in place for the specific areas which require them.
Therefore, at this time, we are requesting Authorization of the proposed project under the Tar -Pamlico
Buffer Rules. Consideration of this project is greatly appreciated. If you should have any questions or
require additional information, please do not hesitate to contact me at (984)255-2361.
Sincerely,
Timmons Group

On -Site Determination for Applicability to the Tar -Pamlico River Riparian Area Protection Rules (15A
NCAC 2B.0259)
Dear Mr. Keller.
On November 12, 2014, at your request, Mr. Roberto Scheller of this Office conducted an on-site determination of a
drainage features located at the subject property. The drainages were reviewed for applicability to the Tar -Pamlico Buffer
Rules in accordance with (15A NCAC 2B .0259). The features are labeled as "# 008 to # 016" on the attached maps and
initialed on October 10, 2014.
The Division of Water Resources (DWR) has determined that the features labeled as "# 008 and # 011" on the
attached maps and highlighted in blue are subject to the Tar -Pamlico Buffer Rules. The features labeled as " #
009, # 010, #012, # 013, # 014, # 015 and, # 016" on the attached maps and highlighted in red are not subject to the
Tar -Pamlico Baffer Rules. Please note that the feature highlighted in yellow does not exist on the ground as depicted on
the Edgecombe County NRCS Soil Survey. The confluences of the aforementioned drainage features that now into
Mitchell Swamp Canal and Knight Canal are marked on the ground with yellow DWQ flagging and are illustrated on the
enclosed maps.
The owner (or future owners) should notify the DWR (and other relevant agencies) of this decision in any future
correspondences concerning this property. This on-site determination shall expire five (5) years from the date of this
letter. Landowners or affected parties that dispute a determination made by the DWR or Delegated Local Authority that a
surface water exists and that it is subject to the buffer rule may request a determination by the Director. A request for a
determination by the Director shall be referred to the Director in writing c/o Karen Higgins, 1650 Mail Service Center
