Dear Mr. Bailey and Ms. Homewood:
Mr. Brian Hall, TDO Land Holdings, LLC, received Notices of Violations (NOVs) from the U.S. Army
Corps of Engineers (USACE) dated September 28, 2017 and the North Carolina Department of
Environmental Quality Division of Water Resources (NCDEQ-DWR) dated September 20, 2017 in
regards to the Department of Army (DA) Individual 404 Permit authorization dated April 4, 2016
and the NCDEQ-DWR 401 Individual Water Quality Certification 004050 dated February 25, 2016.
The applicant provided electronic mail (e-mail) responses dated September 20 and 22, 2017 and
a letter dated September 23, 2017 to address specific concerns associated with de -watering
down -gradient waters due to the use of a diversion ditch. The applicant provided a letter dated
October 5, 2017 that provided information addressing the causes to the specific violations and a
proposal to prevent and avoid further non-compliance. On behalf of the applicant, TDO Land
Holdings, LLC, the purpose of this letter is to provide requested responses and following actions
that address the specific compliance concerns.
NCDEQ-DWR Required Response 1: You must immediately develop and implement a modified
dewatering plan that provides for re-establishment of hydrology into the stream channel below
the impact area. You must notify the Winston Salem Regional Office upon completion of this
requirement.
PO Box 128, Kernersville, NC 27285

Pilot Project 1010.1
November 3, 2017
USACE Follow Action C: Disclose the length of time that the approximately 304 linear feet of
perennial stream was dewatered downstream of the construction area, and propose a plan to
mitigate for the temporal loss of stream function.
Applicant Response: The diversion ditch was installed on June 15, 2017. It was operational until
September 19, 2017, as indicated in the previously provided e-mail and letters dated September
20, 22 and 23, 2017. Pilot visually inspected the stream hydrology immediately down -gradient
of the impact area on September 20, 2017. Aquatic life was observed in the down -gradient reach
immediately down -gradient of the impact area during our field visit. Based on the relative short
duration the stream was temporarily de -watered and the immediate response of aquatic species
following corrective measures, the applicant is not proposing compensatory or other mitigation
for the temporal loss of stream hydrology.
NCDEQ-DWR Required Response 2: Please provide documentation to the Division that
compares the permitted impacted areas as they currently exists. If this evaluation shows
additional permanent impacts to either the stream or wetlands then you must provide a plan to
show how the project will be brought back into compliance with the Water Quality Certification
or submit an application for a modification to the Individual Water Quality Certification.
USACE Following Action A: Using a licensed Professional Land Surveyor, provide an as -built
survey of the current fill limits, including locations of the culvert pipe and headwall, up- and
down -stream impervious dikes, and water diversion channel, overlayed on the wetland and
stream boundaries as approved by the Corps.
Provide the permanent and temporary wetland and stream impacts (acres and
linear feet, respectively) as currently constructed, and compare with those
impacts approved per the DA Individual Permit dated April 4, 2016;
ii. Further, overlay the current fill limits over the Conservation Area boundaries to
determine if any encroachment has occurred.
Applicant Response: The applicant has completed an as -built survey of requested elements by
a Professional Land Surveyor. A copy of the As -Built survey is included as an attachment. The
table below summarizes authorized impacts compared to current conditions.
As the As -Built survey shows the current and final proposed wetlands impacts will be 623 square
feet less than authorized. According to the As -Built survey, the Applicant is outside of permitted

limits by 16 linear feet of permanent stream impact, 60 linear feet of temporary stream impact
and 0.16 acres of temporary wetland impact. Through design changes as required by other
agencies and summarized within the October 5, 2017 letter, the Applicant proposes to be within
the permanent authorized stream impact limits of 205 linear feet by removal of the of 16 linear
feet of rip -rap dissipater pad. Additionally, the Applicant proposes a restoration plan that is
detailed below and within the attachments of this letter to restore temporary impacts to the
stream and wetlands. Based upon these corrective action measures, it is the opinion of the
Applicant that an application for a permit modification or after the fact permit authorization is
not necessary.
According to the As -Built survey, the final proposed conditions will result in no net loss of linear
feet of stream channel or wetlands protected by the recorded conservation easement. Due to
design changes, there is encroachment of permanent disturbance into recorded conservation
areas as shown within the As -Build survey. However, these areas can be off-site by adding areas
of temporary disturbance that is not currently within the recorded conservation easement.
Therefore, following the implementation and agency written notice of success of the restoration
plan, the Applicant proposes to complete and record an updated conservation easement that
results in no net loss of protected waters. The Applicant will provide the updated conservation
easement to the agencies for their records following recording with the local register of deeds.
Due to no net loss of protected linear feet of stream or wetlands within the initial conservation
easement compared to the updated conservation easement, it is the opinion of the Applicant
that a permit modification, additional compensatory mitigation or other corrective actions are
not necessary for compliance with the mitigation conditions of the previous agency
authorizations.
NCDEQ-DWR Required Response 3: Please provide a stream restoration plan for the
temporarily impacted area from the upstream dike to the culvert inlet. The restoration plan must
include a profile drawing utilize natural channel techniques appropriate for the stream bed slope
to the maximum extent possible. You must not redirect flow into the culvert until this restoration
plan has been approved by the Division and the US Army Corps of Engineers.
USACE Following Action B: The vertical elevation difference between the un -impacted stream
channel at the head of the upstream diversion dike and the culvert pipe invert is approximately
3 feet, and therefore presents a danger of headcutting in the stream at such time that stream
flow is directed into the culvert. Provide a plan to provide for continued stability of this channel
while maintaining aquatic function; such proposals should include controlling
headcutting/instability upstream of the culvert inlet using natural channel design principles (i.e.
cross vane, step downs, etc.) and planting of appropriate wetland/riparian vegetation. Stream
flow should not be directed into the culvert pipe until this plan is approved and implemented.
USACE Following Action D: Provide a written plan for resolving non-compliance items 1 and 2
above to the satisfaction of the Corps, pertaining to the following options:

Pilot Project 1010.1
November 3, 2017
i) Generally, resolution of these issues involves rehabilitation of the structure to be in
compliance with the workplans included in the DA Individual Permit dated April 4, 2016.
Such a proposal should provide construction sequencing and timing of those activities.
The proposal should also include detailed plans to restore the unauthorized impacts to
wetland and stream areas back to original grade and contour with suitable
soils/substrate, appropriate natural channel design for stream areas, and a revegetation
plan for wetland areas and stream banks. A monitoring plan to ensure restoration success
should also be included, along with a contingency plan if those restoration efforts do not
succeed;
ii) You also have the option to apply for an after -the -fact permit modification. Please be
aware that, through the permitting process you are required to demonstrate purpose and
need of the project, avoid and minimize your impacts to waters to the maximum extent
practicable, and provide compensatory mitigation for any lost function of the aquatic
resources. Keep in mind that you will be required to remove all discharged dredged and
fill material and provide restoration to the satisfaction of this office (see item C.ii. above)
for those areas of impacted waters of the U.S. that you do not receive after -the -fact
authorization. Importantly, the Corps' evaluation of your original permit application and
subsequent approval was based on an analysis of alternatives including other on-site
crossing locations. Both your preferred alternative (eventually permitted) and Alternative
Crossing Location 3 proposed fewer stream and wetland impacts than the existing non-
compliant structure and fill limits. Further, per 40 CFR 230, sunk costs related to
investments in the partially installed culvert pipe and headwall cannot be used in the
evaluation of alternatives or determination of the least environmentally damaging
practicable alternative (LEDPA).
Applicant Response: The Applicant has prepared the attached restoration plan for temporary
impacts to the stream and wetlands. The plan includes restoration of authorized temporary
impacts to streams and wetlands in addition to those unauthorized.
Following implementation and construction of the restoration plan and other above corrective
measure to bring the project into compliance, the Applicant will contract with an environmental
consultant to provide visual periodic inspection of the restoration areas and re -planting areas for
one year. Visual inspections will be completed to evaluate stability and determine if repairs are
needed. One year following construction, the consultant will prepare an annual report for agency
review that includes any repair activities completed, photographs documenting conditions of the
restoration areas, the success rates of plantings and the overall success of the restoration efforts.

Pilot Project 1010.1
November 3, 2017
The applicant is requesting agency review and approval of the corrective actions to bring the
proposed project into compliance with DA Individual 404 Permit authorization dated April 4, 2016
and the NCDEQ-DWR 401 Individual Water Quality Certification 004050 dated February 25, 2016.

tamped. Remove all debris from the pit and tamp loose soil in the bottom of the pit by hand. Remove the plant by inverting the container and pushing
/ / l on the container bottom. If roots are concentrated along the inside surface of the plant pot, the surface of the plant root ball should be scarified to
encourage outward growth into the soil of the planting pit. Place the plant straight in the center of the planting pit, carrying the plant by the root
X920 mass. All planting holes shall be dug by hand using a mattock, pick or iron bar and planting holes shall be deep enough to allow the first lateral root of
the root mass to be flush with the existing grade. Remove all non-organic debris from the hole and tamp loose soil in the bottom of the hole by hand.
When planting, spread roots in the hole and gradually backfill with soil. Firm the soil, being careful to avoid breaking roots, fill hole with water
(weather permitting), and backfill with additional soil as necessary. Hand tamp as hole is being backfilled to completely fill all voids and air pockets. Do
not over compact soil. Make sure plant remains straight during backfilling/tamping procedure. A
/ N LIVE STAKE: All live stakes split during installation may be left in place, but must be supplemented with a new live stake that remains un -split after

HERBACEOUS: All areas to be seeded shall conform to the finished grades as specified on the plans and be free of weeds, trash, debris, brush, clods,
loose stones and other foreign materials larger than three inches (3") in diameter or length that would interfere with seeding. All gullies, washes, or
disturbed areas that develop subsequent to final dressing shall be repaired prior to seeding. Apply fertilizer In accordance with these specifications.
Seeding shall be accomplished by using a broadcast spreader. When seed is installed by a broadcast spreader, it shall be capable of placing seed at the
specified rate. Seed shall be applied in two different directions and thoroughly covered with %" inch of topsoil. Immediately after seeding, the site
shall be watered lightly but thoroughly so that the top 4 inches of soil is saturated.
LIMITATION OF MACHINERY: Wetlands will be restored to similar pre -construction conditions and grades. Contractor shall minimize use of all
RESTORATION PLAN construction equipment within restoration area to maximum extent practical. Soil removal shall be done with an extended trackhoe whereas possible
1" = 10' to avoid compacting existing native soils. Handwork is to accompany the use of the trackhoe to provide a finished grade to match the pre -disturbance
grades.

encourage outward growth into the soil of the planting pit. Place the plant straight in the center of the planting pit, carrying the plant by the root
mass. All planting holes shall be dug by hand using a mattock, pick or iron bar and planting holes shall be deep enough to allow the first lateral root of
the root mass to be flush with the existing grade. Remove all non-organic debris from the hole and tamp loose soil in the bottom of the hole by hand.
When planting, spread roots in the hole and gradually backfill with soil. Firm the soil, being careful to avoid breaking roots, fill hole with water
(weather permitting), and backfill with additional soil as necessary. Hand tamp as hole is being backfilled to completely fill all voids and air pockets. Do
