ECS Project No. 09-17901A
Gentlemen:
The North Carolina Division of Water Quality (NCDWQ) issued a Notice of Violation dated
October 2, 2009 for Stream Standard Violation and Failure to Secure a 401 Water Quality
Certification to Mr. Gene Lowder for unauthorized impacts to a stream. The letter indicates that
the culvert was installed within a stream channel for the purpose of providing more useable
property and stabilizing the area. The impact occurred prior to the submission of a Pre-
Construction Notification or any authorization, permit or 401 Water Quality Certification from the
Division of Water Quality. The letter concludes that the impacts must be restored or properly
permitted.
Lowder Grading contracted with ECS Carolinas, LLP (ECS) to assist them in restoring the stream
and adjacent buffer and securing a Nationwide Permit (NWP) and a 401 Water Quality
Certification. Based on conversations between ECS and Ms. Sue Homewood with the NCDWQ it
was determined that the stream and stream side buffers must be restored to natural or near
natural conditions. Vegetative plantings will be required along the stream bank and in buffers
around the stream. Grading and seeding will be required to stabilize the stream banks and
buffers. Following restoration activities, the agencies will not allow mowing in buffers around the
stream so that these areas can naturalize.
ECS has prepared construction, planting and monitoring plans intended to correct the above
violation. The eastern portion of the site contains buildings and parking areas for grading
equipment. The western portion of the site contains undeveloped, graded land that is used for
storing mulch. The culvert installed in the stream provides access to the western portion of the
site. The culvert is 225 feet long. The purpose of this submittal is to apply for a Nationwide

ECS Project No. 09-17901A
December 30, 2009
Permit 39 for impacts to 149 linear feet of stream (136 feet of culvert and 15 feet of rip rap) and a
Nationwide Permit 27 for restoring 76 linear feet of stream channel.
Construction Plan
A restoration plan has been prepared. Approximately 91 linear feet of the culvert will be removed
and approximately 76 linear feet of the stream will be restored. The stream banks will be graded,
seeded and covered with reinforced turf matting for stability. Log drops will be installed to stop
head cutting. All disturbed areas will be reseeded and mulched. Construction sequencing, plans,
profiles, construction and erosion control details, seeding specifications and planting details are
attached.
Planting Plan
A thirty foot streamside buffer will be planted. A listing of acceptable species in the piedmont
region is attached. The quality, size, genus, source, species, and variety of tree and shrub
plantings indicated should comply with applicable requirements of ANSI Z60.1 "American
Standard for Nursery Stock". Seedlings should be planted between October 15th and March 15th
only. See the attached drawings for the area that will be replanted.
The planting shall consist of containerized one-gallon or three-gallon trees and shrubs. The
seedlings should be planted at a density of approximately 470 stems per acre to ensure that the
target density of 320 stems per acre is achieved at maturity. A mixture of shrubs and trees shall
be planted in the vegetative buffer area with predominately shrubs along the stream bank and
predominately trees further away from the stream. To achieve the desired density, the
approximate planting density to be used is 10' x 10' spacing. If, at the end of one year after
planting, the number of viable trees present within the planted area is insufficient to provide a
target density of no less than 320 trees/acre at maturity (approximately five years), additional trees
should be planted to ensure that the target density objective is reached.
Monitoring Plan
Based on conversations with Ms. Sue Homewood, vegetative plantings and stream work must be
monitored and reported after the first year of construction/planting. Throughout the first year after
construction, ECS plans to perform several visual reconnaissances to evaluate the success of the
restoration. ECS will document the visits with photographs and evaluate the area for evidence of
stream and bank erosion or other damages. In addition, ECS will conduct a complete stem count
of planted vegetation to determine the success rate of the plantings. Photographs and findings
will be presented to the USACE and the NCDWQ.

Subject: NOTICE OF VIOLATION and RECOMMENDATION FOR ENFORCEMENT
Failure to Obtain a 401 Water Quality Certification
Lowder Recycling, Parcel ED # 6813-15-6135.00
Forsyth County
Dear Mr. Lowder:
Dee Freeman
Secretary
On September 25, 2009, Sue Homewood of the Division of Water Quality (DWQ) Winston-Salem Regional Office
conducted a site visit of the your property located on Griffith Rd in Forsyth County, NC. At that time the inspector
observed that a culvert had been installed within a stream channel for the purpose of providing you more useable property
and stabilizing the area. An Unnamed Tributary to the Salem Creek, Class C waters in the Yadkin Pee Dee River Basin
was impacted.
Accordingly, DWQ site visits and file review confirms that impacts to the stream occurred prior to the submission of a
Pre-Construction Notification or any authorization, permit or 401 Water Quality Certification from the Division of Water
Quality. As a result of the site inspection and file review, the following violations are noted:
Item I. Failure to Secure a 401 Water Quality Certification
Impacts to a stream have occurred at this tract from culvert installation to approximately 200 linear feet of an unnamed
tributary to Salem Creek. A 401 Water Quality Certification has not been issued or authorization has not been sought. A
401 Water Quality Certification is required for the above-mentioned impacts pursuant to 15A NCAC 2H .0500.
Additionally, earthen fill to streams or wetlands requires proper permitting from the US Army Corps of Engineers and
proper authorization from the NC Division of Water Quality with a 401 Water Quality Certification.
These impacts must be restored or yroverly permitted If these impacts are to remain onsite, or additional impacts are to
occur, a respective 404 Permit from the US Army Corps of Engineers and corresponding 401 Water Quality Certification
from DWQ must be obtained. If you need assistance with these efforts, please call John Thomas with the US Army Corps
of Engineers at [phone] ext, 25 or Sue Homewood with the NC DWQ at [phone].

Requested Response
This Office requests that you respond to this letter in writing within 30 days of Receipt of this Notice.
Your response should address the following items:
1. Please provide a map that details amount and location of streams that were impacted.
2. It is required that you obtain authorization for the stream impacts, restore the area, or a combination of both.

04 Definition A. structure designed to control erosion at the outlet of a channel or conduit.
Purpose To prevent erosion at the outlet of a channel or conduit by reducing the velocity
of flow and dissipating the energy.
Conditions Where This practice applies where the discharge velocity of apipe, box culvert, diver-
Practice Applies lion, open channel, or other water conveyance structure exceeds the permissible
velocity of the receiving channel or disposal area.
Planning The outlets of channels, conduits, and other structures are points of high erosion
Considerations potential, because they frequently carry flows at velocities that exceed the al-
lowable limit for the area downstream. To prevent scour and undermining, an
outlet stabilization structure is needed to absorb the impact of the flow and
reduce the velocity to non-erosive levels. A riprap-lined apron is the most com-
monly used practice for this purpose because of its relatively low cost and ease
of installation. The riprap apron should be extended downstream until stable
conditions are reached even though this may exceed the length calculated for
design velocity control.
Riprap-stilling basins or plunge pools reduce flow velocity rapidly. They should
be considered in lieu of aprons where overfalls exit at the ends of pipes or where
high flows would require excessive apron length. Consider other energy dis-
sipators such as concrete impact basins or paved outlet structures where site con-
ditions warrant, (Figure 6.41 a).
Design Criteria Design procedures for riprap outlet structures are presented in Appendix 8.06.
The criteria for design of riprap outlets are:
Capacity-10-yr, peak runoff or the design discharge of the water conveyance
structure, whichever is greater.
Tailwater depth--Determine the depth of tailwater immediately below the
pipe outlet based on the design discharge plus other contributing flows. If the
tailwater depth is less than half the diameter of the outlet pipe and the receiving
stream is sufficiently wide to accept the divergence of flow, it is classed as a
minimum tailwater condition. If the tailwater depth is greater than half the
pipe diameter, it is classed as a maximum tailwater condition. Pipes that out-
let onto broad flat areas with no defined channel may be assumed to have a min-
imum tailwater condition unless site conditions indicate otherwise (Figure
6.41b).
Apron size-The apron length and width can be determined according to the
tailwater condition. If the water conveyance structure discharges directly into
a well-defined channel, extend the apron across the channel bottom and up the
channel banks to an elevation of 0.5 ft above the maximum tailwater depth or
to the top of the bank, whichever is less (Figure 6.41c).

Determine the maximum allowable velocity for the receiving stream, and design
the riprap apron to reduce flow to this velocity before flow leaves the apron.
r,alculate the apron length for velocity control or use the length required to meet.
stable conditions downstream, whichever is greater.
Grade-Ensure that the apron has zero grade. There should be no overfall at
the end of the apron; that is, the elevation of the top of the riprap at the
downstream end should be the same as the elevation of the bottom of the receiv-
ing channel or the adjacent ground if there is no channel.
Alignment-The apron should be straight throughout its entire length, but if a
curve is necessary to align the apron with the receiving stream, locate the curve
in the upstream section of riprap.
Materials-Ensure that riprap consists of a well-graded mixture of stone.
Larger stone should predominate, with sufficient smaller sizes to fill the voids
between the stones. The diameter of the largest stone size should be no greater
than 1.5 times the d50 size.

Practice Standards and Specifications
Thickness--Make the minimum thickness of riprap 1.5 times the maximum
stone diameter.
Stone quality-Select stone for riprap from field stone or quarry stone. The
stone should be hard, angular, and highly weather-resistant. The specific gravity
of the individual stones should be at least 2.5.
Filter-Install a filter to prevent soil movement through the openings in the
riprap. The filter should consist of a graded gravel layer or a synthetic filter
cloth. Design filter blankets by the method described in Practice 6.15, Riprap.
Construction 1. Ensure that the subgrade for the filter and riprap follows the required lines
s and grades shown in the plan. Compact any fill required in the subgrade to the
SpeClflCatl®n
density of the surrounding undisturbed material. Low areas in the subgrade on
undisturbed soil may also be filled by increasing the riprap thickness.
2. The riprap and gravel filter must conform to the specified grading limits
shown on the plans.
3. Filter cloth, when used, must meet design requirements and be properly
protected from punching or tearing during installation. Repair any damage by
removing the riprap and placing another piece of filter cloth over the damaged
area. All connecting joints should overlap a minimum of 1 ft. If the damage is
extensive, replace the entire filter cloth.
4. Riprap may be placed by equipment, but take care to avoid damaging the fil-
ter.
5. The minimum thickness of the riprap should be 1.5 times the maximum stone
diameter.
6. Riprap may be field stone or rough quarry stone. It should be hard, angular,
highly weather-resistant and well graded.
7. Construct the apron on zero grade with no overfall at the end. Make the top
of the riprap at the downstream end level with the receiving area or slightly
below it.
8. Ensure that the apron is properly aligned with the receiving stream and
preferably straight throughout its length. If a curve is needed to fit site condi-
tions, place it in the upper section of the apron.
9. Immediately after construction, stabilize all disturbed areas with vegetation
(Practices 6. 10, Temporary Seeding, and 6.11, Permanent Seeding).
Maintenance inspect riprap outlet structures after heavy rains to see if any erosion around or
below the riprap has taken place or if stones have been dislodged. Immediately
make all needed repairs to prevent further damage.

3. Project Description
3a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this
application:
The site is occupied by Lowder Grading, Inc. The eastern portion of the site contains buildings and parking areas for
grading equipment. The western portion of the site contains undeveloped, graded land that is used for storing mulch. A
culvert installed in a stream provides access to the western portion of the site. The culvert is 225 feet long. An NOV was
issued by the NCDENR on October 2, 2009. The letter indicates that the culvert was installed within a stream channel for
the purpose of providing more useable property and stabilizing the area. The impact occurred prior to the submission of a
Pre-Construction Notification or any authorization, permit or 401 Water Quality Certification from the Division of Water
Quality. The letter concludes that the impacts must be restored or properly permitted. The purpose of this submittal is to
obtain nationwide permits for the culvert that will remain on the site and to restore the lower reach of the stream.
3b. List the total estimated acreage of all existing wetlands on the property:
0.1
3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property:
400
3d. Explain the purpose of the proposed project:
The purpose of the proposed project is to reduce the existing impacts, restore the stream and obtain permits for a road
crossing that will provide access to the western portion of the site.
3e. Describe the overall project in detail, including the type of equipment to be used:
Approximately 91 feet of culvert will be removed to reduce the impacts. After being removed, a rip rap dissipator will be
installed at the end of the culvert that will impact 15 feet of the stream, immediately adjacent to the existing culvert.
Approximately 76 linear feet of stream will be restored. During the construction activities, water will be pumped around
the construction site into a temporary retention basin before being discharged into the main stream. The attached plan
details the proposed stream restoration activities. The work will be done using a backhoe, bulldozers, dump trucks and
other grading equipment. Buffers will be established and planted with bottomland hardwood species and the area will be
seeded and matted.

D. Impact Justification and Mitigation
?1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Mr. Gene Lowder contracted Mr. Barry Nelson, a hydrologist with Engineering Techtonics, to perform a wetland determination
on the site in July 2000. Based on Mr. Nelson's letter to Mr. Lowder (included as an attachment), the site does not have
wetland "hydrology" and would fail to qualify for the wetland definition of the Corps of Engineers. Mr. Lowder provided ECS
with photographs showing the feature after the site had been cleared and graded (included as attachments). Mr. Lowder
informed us that there was no water flowing through the feature at the time of the photographs. Mr. Lowder informed us that
based on correspondence with Engineering Techtonics and his observations, he did not know that permits were required.
The current proposal is to remove 91 feet of culvert from the stream. This will limit the culvert impacts to 134 linear feet. Rip
rap will be installed at the outlet of the culvert that will impact 15 linear feet of stream channel. The rip rap will protect the
integrity of the culvert and will prevent scouring and sediment discharge. The slopes will be 2:1 at each end of the culvert.
The remaining road will be less than 100 feet wide. The road will provide access for skidders, pans, trackhoes, bulldozers,
dumptrucks, wide trailers, chippers and other large grading equipment to the western portion of the site. The lower portion of
the stream will be restored. Upon completion of the proposed project, approximately 250 linear feet of stream channel will be
left undisturbed/restored from the current conditions. The wetlands on the site will not be impacted.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
During pipe removal and restoration activities, water will be diverted around the construction area and into a temporary
sediment basin with a rock weir before enetering the stream that is located along the southern boundary. The restoration area
will be seeded and matted to prevent sediment from entering the stream before water will be released into the restored stream
channel.
2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State

5a. If using a permittee responsible mitigation plan, provide a description of the proposed mitigation plan.
As part of the proposed project, ECS is preparing a mitigation plan for 91 linear feet of stream channel that will be
daylighted as a result of removing the lower end of the culvert. Rip rap will be installed for dissipation and to prevent
scouring that will impact 15 linear feet of the daylighted channel. The remaining 76 linear feet of stream channel will be
restored, the banks will be seeded and matted, and trees will be planted in the adjoining flood plain. A copy of the
mitigation plan is included as an attachment.

Comments:
2. Violations (DWQ Requirement)
2a. Is the site in violation of DWQ Wetland Rules (15A NCAC 2H .0500), Isolated
Wetland Rules (15A NCAC 2H .1300), DWQ Surface Water or Wetland Standards, ® Yes ? No
or Riparian Buffer Rules (15A NCAC 2B .0200)?
2b. Is this an after-the-fact permit application? ® Yes ? No
2c. If you answered "yes" to one or both of the above questions, provide an explanation of the violation(s): A culvert has been
installed in a stream that provides access to the western portion of the site. The culvert is 225 feet long. An NOV was issued
by the NCDENR on October 2, 2009. The NOV indicates that the culvert was installed within a stream channel for the
purpose of providing more useable property and stabilizing the area. The impact occurred prior to the submission of a Pre-
Construction Notification or any authorization, permit or 401 Water Quality Certification from the Division of Water Quality.
The NOV concludes that the impacts must be restored or properly permitted. The purpose of this submittal is to obtain
nationwide permits for the culvert impact that will remain and to restore the lower reach of the stream.
3. Cumulative Impacts (DWQ Requirement)
3a. Will this project (based on past and reasonably anticipated future impacts) result in ? Yes ® No
additional development, which could impact nearby downstream water quality?
3b. If you answered "yes" to the above, submit a qualitative or quantitative cumulative impact analysis in accordance with the
most recent DWQ policy. If you answered "no," provide a short narrative description.
This project will not result in additional development. The project will benefit water quality by restoring a reach of stream
channel.
4. Sewage Disposal (DWQ Requirement)
4a. Clearly detail the ultimate treatment methods and disposition (non-discharge or discharge) of wastewater generated from
the proposed project, or available capacity of the subject facility.
The buildings on the site are connected to City of Winston-Salem sanitary sewer system.

5. Endangered Species and Designated Critical Habitat (Corps Requirement)
5a. Will this project occur in or near an area with federally protected species or ? Yes ® No
habitat?
5b. Have you checked with the USFWS concerning Endangered Species Act Yes No
impacts?
? Raleigh
5c. If yes, indicate the USFWS Field Office you have contacted.
? Asheville
5d. What data sources did you use to determine whether your site would impact Endangered Species or Designated Critical
Habitat?
We reviewed the endangered species list that is maintained by the North Carolina Natural Heritage Program to determine
if federally protected endangered or threatened species or associated habitat are located on the Winston-Salem West,
NC Quadrangle (the quadrangle that contains the site). The list identifies the Bog Turtle (Glyptemys muhlenbergii) as a
federally protected threatened species (due to similarity of appearance). This vertebrate animal inhabits bogs, wet
pastures and wet thickets. We did not observe this species or suitable habitat for this species on the site. Based on our
observations, there are no federally protected threatened or endangered species or potential habitat on the site.
6. Essential Fish Habitat (Corps Requirement)
6a. Will this project occur in or near an area designated as essential fish habitat? ? Yes ® No
6b. What data sources did you use to determine whether your site would impact Essential Fish Habitat?
The site is located in a watershed that is rated as Class C by the NCDENR. The waters on the site are not identified as
trout waters. The endangered species list did not identify federally protected fish species that may use the site. We did not
observe fish inhabiting the stream on the site.
7. Historic or Prehistoric Cultural Resources (Corps Requirement)
7a. Will this project occur in or near an area that the state, federal or tribal
governments have designated as having historic or cultural preservation ? Yes ® No
status (e.g., National Historic Trust designation or properties significant in
North Carolina history and archaeology)?
7b. What data sources did you use to determine whether your site would impact historic or archeological resources?
The site has been cleared and graded and used for a mulch storage yard. No artifacts have been encountered during
grading activities. No historic structures have been located on the site.
8. Flood Zone Designation (Corps Requirement)
8a. Will this project occur in a FEMA-designated 100-year floodplain? ® Yes ? No
8b. If yes, explain how project meets FEMA requirements: Portions of the project will be in Zone X and Zone AE. The project
will not be in a designated floodway. The project will be removing soil from the restoration area which will provide more
area for the 100 year flood. No fill will be brought in that will effect the 100 year floodplain.
8c. What source(s) did you use to make the floodplain determination? FEMA Maps, included as attachments.

RE: Historical Aerial Photo Review
Griffith Drive @ NAfWT1P
Forsyth County, North Carolina
Dear Gene,
:1? ems.
?. 71 1 n;nld1 Inc.
Engineering Tectonics P. A. has completed a ;review of the aerial photographs
of the site across from the City of Winston-Salem Waste Water Treatment Plant
on Griffith Road.
A summary of the photographs of the property is provided below. Based on
our review, we did not observe any indications of adverse land uses that would
preclude your land purchase and development.
Historical Aerial Photograph Review:
1951 (Map r 153) Open pasturage, no wetlands. Pass ure to creel- bed.
1958 (Map # 4-03) Open grass with hay crops. No WVVl'P yet.
1966 (Map 'r 96) WWTP in place at this time. Grass with hay crops. No
wetlands or industry present.
198A (/lap # 21-438) Open, no concrete plant. Residential and light industry
present at this time.
1990 (Map # E 11) Unidentified _)?Iindrical concrete structures northwest of
site.
a I
1994 (Map =r 606834) Loaded with potential wetlands. Concrete structures
from 1990 map no longer present.

Attn: Gene Lowder
Subject: Jurisdictional Wetlands
Griffith Road Site
Dear Gene:
As per your request, Engineering Tectonics, P.A. has obtained a copy of the Forsyth County
USDA Soil Conservation Service Soil Survey. We have identified the Grifith Road Tract and
determined that there are no wetland soils on the tracts that would qualify as jurisdictional
wetlands by the US Army Corps of Engineers. During a couple of site walkovers, we did not
observe sufficient condtions of "hydrology" that would put the watertabl.e at or within 6-12 inches
of the land surface with the exception of in the watercourses or streambeds. Therefore, the
absence of this condition leads us to believe that the site would fail to qualify for the wetland
definition of the Corps of Engineers.
Should you have any questions or desire additional information, please do not hesitate to contact
us. Thank you for your business.
Very truly yours,
ENGINEERING TECTONICS, P.A.
