Dear Mr. Wynn:
On December 19, 2008, Lauren Witherspoon and Natalie Landry from the Raleigh Regional Office of the
Division of Water Quality (DWQ) conducted a site inspection for the tract/project known as Southfork
Subdivision/Olde Brassfield Subdivision Phase 2 located off of Old Franklinton Road (SR 1705) south of
Wilton in Granville County, North Carolina. The streams on the site are unnamed tributaries (UT) to
Ford Creek and Ford Creek, Class C NSW waters in the Tar-Pamlico River Basin.
Accordingly, the following observations were noted during the DWQ file review:
Summit Consulting Engineers submitted a Pre-Construction Notification (PCN) dated December 16, 2005
and additional information received by DWQ on February 8, 2006 on behalf of Crosswind Properties,
LLC - Mr. Bill Wynn - Wynn Construction. The impacts were requested under U.S. Army Corps of
Engineers Nationwide Permit 14 and the corresponding General Water Quality Certification Number
3404 (GC3404). DWQ issued an approval for the impacts dated February 13, 2006 (DWQ Project # 06-
0061).
The 401 Water Quality Certification (DWQ Project# 06-0061) authorizes to place fill or otherwise impact
0.086 acres of wetland, 250 linear feet of stream, and 13,137 square feet of-protected riparian buffers. In
addition, eight (8) level spreaders depicted on Drawing No. 1 of 2 of the plans dated February 8, 2006
were included in this approval.

A buffer determination was made by Eric Kulz (DWQ personnel) on March 1, 2005 (letter dated March 7,
2005 - TPBRRO 05-055) for this tract/project which was named the Yarborough Site at that time.
DWQ observations during the December 19, 2008 site inspection and file review include:
Impact Area #1 identified in the February 8, 2006 PCN application:
o Approximately 105 LF of stream had been impacted to include 62 LF of culvert impacts, 17 LF
of excavation both upstream and downstream of the culvert (total 34 LF), and a 9 LF check dam
downstream from the culvert;
o The 401 authorized 108 LF of stream impacts which includes a 36 LF dissipator pad that had not
been installed;
o Level Spreaders 7 and 8 had not been installed resulting in severe erosion around the headwalls
and lack of diffuse flow through the buffer;
o Level Spreaders 6 and 9 were not functioning properly resulting in severe erosion around the
headwalls and lack of diffuse flow through the buffer;
o Level Spreader 9 measured approximately 16 LF while the 401 WQC approval dated February
13, 2006 required the minimum length to be 19.74 LF;
o The stream and buffer at Impact #1 was not included in the buffer determination letter
(TPBRRO 05-055 dated March 7, 2005) and is not depicted correctly on Drawing No. 1 of 2.
The extent of the stream and buffer should be shown on maps throughout the tract.
Impact Area #2 identified in the February 8, 2006 PCN application:
o Approximately 94 LF of stream channel had been impacted to include approximately 64 LF of
culvert impacts and 30 LF of streambank disturbance downstream of the culvert;
o Approximately 30 LF of stream channel downstream of the culvert had been impacted by
sediment deposition measuring 4-5 inches in depth;
o The 401 authorized 142 LF of stream impacts that includes a 60 LF dissipator pad that had not
been installed. The 401 authorization does not include sediment impacts which are not
permittable;
o The culvert at this road crossing is perched by at least 6 inches above the substrate of the stream;
o No level spreaders had been installed resulting in severe erosion, the instability of the headwalls,
and lack of diffuse flow through the buffer.
Stream and Wetland Impacts not identified in the PCN application and not approved by DWQ:
o Approximately 310 LF of stream channel [identified as Stream B in the buffer determination
letter (TPBRRO 05-055) dated March 7, 2005] had been impacted to include approximately 63
LF of culvert impacts associated with a road crossing, 83 LF from the placement of a sediment
basin and rip rap, and 164 LF of sediment deposition measuring 6-18 inches in depth. These
impacts were not approved by DWQ;
o Approximately 5,229 square feet of Tar-Pamlico riparian buffer was impacted adjacent to
Stream B in association with the unauthorized road crossing and installation of a sediment basin;
o A wetland adjacent to this stream channel (Stream B) was impacted as a result of sediment
deposition measuring 3-12 inches in depth.
o Approximately 2,783 square feet of sediment was observed outside the limits of disturbance
above the origin of Stream B. This does not include jurisdictional impacts.
A stormwater general permit is issued upon the approval of an Erosion and Sedimentation Control Plan.
This permit applies to projects that receive a Division of Land Resources (or local delegated program)
Erosion and Sedimentation Control Plan for land disturbance of 1 acre or greater. Specifically, the
stormwater general permit authorizes the discharge of stormwater under the National Pollutant Discharge
Elimination System in accordance with Title 15A North Carolina Administrative Code 211.0100.

The 401 Water Quality Certification DWQ Project# 06-0061 approval letter specifies that the activities
must follow the conditions listed in the General Water Quality Certifications, as well as additional
conditions listed in the letter. Based on site observations and the file review, the following violations of
conditions (see attached 401 WQC) have occurred on the Southfork/Olde Brassfield Subdivision Phase 2:
Condition l: Impacts Approved
The following impacts are hereby approved as long as all of the other specific general conditions of this
Certification are met. No other impacts are approved including incidental impacts.
Amount Approved Units Plan Location or Reference
404 Wetland 0.086 (acres) PCN page 8 of 12
Stream 250 linear feet) PCN page 8 of 12
Zone 1 TPBR Buffer Impacts 9,387 (square feet) PCN age 11 of 12
Zone 2 TPBR Buffer Im acts 3,750 (square feet) PCN page 11 of 12
Condition 3:
No waste, spoil, solids, or fill of any kind shall occur in wetlands, waters, or riparian areas beyond the
footprint of the impacts depicted in the 404/401 Permit Application. All construction activities, including
the design, installation, operation, and maintenance of sediment and erosion control Best Management
Practices, shall be performed so that no violations of state water quality standards, statutes, or rules occur.
Condition 7: Culvert Installation
Culverts required for this project shall be installed in such a manner that the original stream profiles are
not altered. Existing stream dimensions (including the cross section dimensions, pattern, and longitudinal
profile) must be maintained above and below locations of each culvert. Culverts shall be designed and
installed to allow for aquatic life movement as well as to prevent head cutting of the streams. If any of
the existing pipes are or become perched, the appropriate stream grade shall be re-established or, if the
pipes are installed in a perched manner, the pipes shall be removed and re-installed correctly.
Page 4
Southfork/Olde Brassfield Subdivision Phase 2
Granville County
Culvert(s) shall not be installed in such a manner that will cause aggradation or erosion of the stream of
the stream up or down stream of the culvert(s). Existing stream dimensions (including the cross section
dimensions, pattern and longitudinal profile) shall be maintained above and below locations of each
culvert.
Placement of culverts and other structures in waters, streams, and wetlands must be placed below the
elevation of the streambed by one foot for all culverts with a diameter greater that 48 inches, and 20
percent of the culvert diameter for culverts having a diameter less than 48 inches, to allow low flow
passage of water and aquatic life. Design and placement of culverts and other structures including
temporary erosion control measures shall not be conducted in a manner that may result in disequilibrium
of wetlands or streambeds or banks, adjacent to or upstream and down stream of the above structures.
This applicant is required to provide evidence that the equilibrium shall be maintained if requested in
writing by DWQ.
Condition 8: Diffuse Flow
All constructed stormwater conveyance outlets shall be directed and maintained as diffuse flow at non-
erosive velocities through the protected stream buffers such that it will not re-concentrate before
discharging into a stream as identified within 15A NCAC 2B .0233 (5).
Item II. Other Waste (in-stream sediment)
The documented in-stream sediment deposition is a violation of 15A NCAC 02B .0211 (3)f which reads
as follows:
Oils; deleterious substances; colored or other wastes: only such amounts as shall not render the waters
injurious to public health, secondary recreation or to aquatic life and wildlife or adversely affect the
palatability of fish, aesthetic quality or impair the waters for any designated uses.
Item III. Removal of Best Usage
The placement of the culvert and sediment basin in Stream B is a violation of 15A NCAC 02B .0211 (2)
which reads as follows:
The waters shall be suitable for aquatic life propagation and maintenance of biological integrity, wildlife,
secondary recreation, and agriculture; sources of water pollution which preclude any of these uses on
either a short-term or long-term basis shall be considered to be violating a water quality standard.
Item IV. Tar-Pamlico River Basin Riparian Buffer Violation
The Buffer Rules apply to riparian buffers directly adjacent to surface waters in the Tar-Pamlico River
Basin (intermittent streams, perennial streams, lakes, ponds and estuaries). The protected buffer extends
50-feet landward from the landward edge of coastal marsh (as identified by the Division of Coastal
Management) or from the top of bank of any feature shown as surface waters on either a paper copy of the
soil survey maps prepared by the Natural Resource Conservation Service of the U.S. Department of
Agriculture or the most recent version of the 1:24000 scale quadrangle topographic maps prepared by the
U.S. Geological Survey. The protected riparian buffer has two zones: Zone 1 consists of a vegetated area
that is undisturbed except for uses provided for in Item (6) of this Rule (Title 15A NCAC 02B .0259);
Zone 2 shall consists of a stable, vegetated area that is undisturbed except for activities and uses provided
for in Item (6) of this Rule (Title 15A NCAC 02B .0259). The purpose of these rules is to protect and
Page 5
Southfork/Olde Brassfield Subdivision Phase 2
Granville County
preserve riparian buffers in the Tar-Pamlico River Basin to maintain the nutrient removal functions of
these streamside areas necessary to protect surface waters.
15A NCAC 0213.0259 (4)
Zones 1 and 2 of the riparian buffer remain in vegetation that is undisturbed except for those uses
provided for in Item (6) of this Rule.
Tar-Pam Buffer - Diffuse Flow
15A NCAC 02B .0259 (5)
Diffuse flow of runoff shall be maintained in the riparian buffer by dispersing concentrated flow and
reestablishing vegetation.
Item V. Wetlands Standards
The observed sediment deposition in wetlands is in violation of 15A NCAC 02B .0231 (b) which reads as
follows:
(1) Liquids, fill or other solids or dissolved gases may not be present in amounts which may cause
adverse impacts on existing wetland uses;
(5) 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;
(F) Water levels or elevations.
Item IV. Stormwater General Permit (NCG010000) Condition Violation
Part I, Section B. No. 1, which reads, "All erosion and sedimentation control facilities shall be inspected
by or under the direction of the permittee at least once every seven calendar days (at least twice every
seven days for those facilities discharging to waters of the State listed on the latest EPA approved 303(d)
list for construction related indictors of impairment such as turbidity or sedimentation) and within 24
hours after any storm event of greater than 0.5 inches of rain per 24 hour period. A rain gauge shall be
maintained on the site and a record of the rainfall amounts and dates shall be kept by the permittee."
Part I, Section A. No. 2, which reads, "The permittee shall implement the plan, which has been approved
by the approval authority. The approved plan is considered a requirement or condition of this general
permit. Deviation from the approved plan, or approved amendment to the plan, shall constitute a
violation of the terms and conditions of this general permit except that deviation from the approved plan
will be allowed (1) to correct an emergency situation where sediments are being discharged off site or (2)
when minor modifications have been made for the purpose of improving the performance of the erosion
and sedimentation control measures and notification of the minor modifications has been made to the
Division of Land Resources (or approved local program). Such a deviation from the approved plan shall
be noted on the approved plan maintained on the job site. During active construction, a copy of the
approved plan shall be maintained on the site."
Part I, Section B. No. 2, which reads, "Once land disturbance has begun on the site, stormwater runoff
discharges shall be inspected by observation for stormwater discharge characteristics as defined below at
the frequency in #1 above to evaluate the effectiveness of the pollution control facilities or practices. If
any visible sedimentation is leaving the disturbed limits of the site, corrective action shall be taken
immediately to control the discharge of sediments outside the disturbed limits."

days of receipt. You are also encouraged to secure a consultant who specializes in stream and wetland
restoration to assist you with the development and submittal of the following:
1. Documentation depicting all jurisdictional features (e.g. streams, buffers, and wetlands). A
description and quantification of all the impacts to those jurisdictional features and your plans to
avoid further stream, buffer, and wetland impacts on the site.
2. Explain in your response how and when you anticipate being in full compliance with the 401
WQC.
3. Please provide a correct depiction of the level spreader locations including the Level Spreader
number. In addition, please include corresponding level spreader calculations.
4. Streambank stabilization around headwalls - Please explain how you plan to stabilize the stream
banks at Impact #1 and Impact #2.
5. Stream and Wetland Restoration Plan (sediment impacts) - The sediment deposition in the
streams and wetland must be removed. As a part of this plan, you should provide the amount
(depth) of material that has been deposited in the streams and wetland. This information should
be depicted on a map you provide. It is recommended that you use hand labor (buckets, shovels
and wheelbarrows) to remove deposited sediment from the wetland and the streams. The
sediment should be removed from the streams and the wetland, taken to high ground (outside the
buffer) and stabilized. Also, the plan must address the measures that will be used for temporary
stabilization/sediment control while this work is under way.
6. Stream Restoration Plan (culvert and sediment basin impacts) - Please explain how you plan to
restore the pattern, profile and dimension of the impacted stream channel to include the removal
of the culvert in Stream B, the sediment basin, and the riprap. The streambed must be restored to
the original profile, the stream banks must be stabilized, and any fill material must be removed
from the riparian zone. Replanting of the riparian zone will be required.
Riparian Zone planting - Please submit a Restoration Plan to this office for review and approval.
This plan must be developed to ensure that at least two native tree species are planted at a density
sufficient to provide 320 trees/acre at maturity. This density is usually achieved by planting
approximately 436 trees/acre on a 10 ft. x 10 ft. grid or 681 trees/acre on a 8 ft. x 8 ft. grid.
Please see the Guidelines for Riparian Buffer Restoration (October 2004) for assistance in
developing your plan (available on the web at: http://www.nceep.net/news/reports/bufferspdf).
This plan must include the types of native woody vegetation selected, methodology of planting,
and a site map indicating the location of the replanting efforts.
8. Explain in your response how and when you anticipate being in full compliance with the
stormwater general permit and your Erosion and Sedimentation Control Plan.
9. Please provide photographs of the rain gauge and a copy of the approved Sedimentation and
Erosion Control Plan maintained on the site and a written description of where on the site the rain
gauge is located.

7. Culvert Installation
Culverts required for this project shall be installed in such a manner that the original stream profiles
are not altered. Existing stream dimensions (including the cross section dimensions, pattern, and
longitudinal profile) must be maintained above and below locations of each culvert. Culverts shall be
designed and installed to allow for aquatic life movement as well as to prevent head cutting of the
streams. If any of the existing pipes are or become perched, the appropriate stream grade shall be re-
established or, if the pipes installed in a perched manner, the pipes shall be removed and re-installed
correctly.
Culvert(s) shall not be installed in such a manner that will cause aggradation or erosion of the stream
up or down stream of the culvert(s). Existing stream dimensions (including the cross section
dimensions, pattern and longitudinal profile) shall be maintained above and below locations of each
culvert.
Placement of culverts and other structures in waters, streams, and wetlands must be placed below the
elevation of the streambed by one foot for all culverts with a diameter greater than 48 inches, and 20
percent of the culvert diameter for culverts having a diameter less than 48 inches, to allow low flow
passage of water and aquatic life. Design and placement of culverts and other structures including
temporary erosion control measures shall not be conducted in a manner that may result in dis- '
equilibrium of wetlands or streambeds or banks, adjacent to or upstream and down stream of the above
structures. The applicant is required to provide evidence that the equilibrium shall be maintained if
requested in writing by DWQ.
The establishment of native, woody vegetation and other soft stream bank stabilization techniques
must be used where practicable instead of rip rap or other bank hardening methods. If rip-rap is
necessary, it shall not be placed in the stream bed, unless specifically approved by the Division of
Water Quality.
Installation of culverts in wetlands must ensure continuity of water movement and be designed
to adequately accommodate high water or flood conditions.
Upon completion of the project, the Applicant shall complete and return the enclosed "Certificate of
Completion" form to notify NCDWQ when all work included in the §401 Certification has been
completed. The responsible party shall complete the attached form and return it to the 401/Wetlands
Unit of the NC Division of Water Quality upon completion of the project. Please send photographs
upstream and downstream of each culvert site to document correct installation along with the
Certificate of Completion form.
S. Diffuse Flow (No Review)
All constructed stormwater conveyance outlets shall be directed and maintained as diffuse flow at
non-erosive velocities through the protected stream buffers such that it will not re-concentrate before
discharging into a stream as identified within 15A NCAC 2B .0233 (5). If this is not possible, it may
be necessary to provide stormwater facilities that are considered to remove nitrogen. This may require
additional approval from this Office.
9. Compensatory Mitigation Using the Ecosystem Enhancement Program (EEP)
Mitigation must be provided for the proposed impacts as specified in the table below. We
understand that you wish to make a payment to the Wetlands Restoration Fund administered
Crosswind Properties, LLC
