WETLANDS AND STORXUAMR ERANCN
Carolina Environmental Consultants (Brandon Fulton) spoke with Mr. Eric Kulz of your
office on July 23, 2010 concerning this project. If at all possible I would like to request that
Eric be the recipient of this application due to his background knowledge of the project.
On behalf of the owner, Cabarrus County Schools (Attn: Len Witke), please find attached a
complete application and supplemental information requesting written concurrence from the U.S.
Army Corps of Engineers (USACE) and the North Carolina Division of Water Quality (NC-
DWQ) for "After the Fact" permitting of activities completed on a culvert
replacementlextension impacting an intermittent unimportant stream. Requested is Nationwide
Permit 14 and Water Quality Certification 3820 to obtain compliance. Addendum to the previous
Jurisdictional Determination to include the culvert location is also being requested from the
USAGE. The "project" with regards to this permit application is in reference to a culvert running
under Miami Church Road in Cabarrus County. Miami Church Road was widened due to
anticipated influx of traffic associated with the newly built AT Allen Elementary School. All
wetland and stream features on the "main" school site were avoided. The "main" school site
exists northwest of the intersection of Miami Church Road and Abilene Road. Upon the
widening of Miami Church Road, Cabarrus County Schools was dedicated an easement for

purpose of improving the existing culvert. This culvert was replaced with a new culvert to
support the road widening activities. Nearing project completion, NC DWQ was called to the site
for erosion complaints from neighboring property owners associated with the "main" school site.
During this inspection, DWQ discovered the culvert extension, and the intermittent stream it had
impacted. An NOV was released to Cabarrus County Schools for the sediment violations;
included in the NOV was a request for the culvert to be permitted for compliance. All other
stormwater and sediment/erosion control issues are being handled by a different consultant and
have since been resolved to my knowledge. According to the DWQ stream origin designation,
impacts will total 60 feet of stream. Impacts totals are measured from the end of the former
culvert (DWQ designated stream origin) to the end of the rip rap dissipation pad of the new
culvert (end of dedicated easement). Please see below for project summaries and impact totals,
as well as attachments.

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1 a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Main school site contains wetland and stream features. Cabarrus County School system completely avoided impacts to both
the wetland and stream on "main school site".The widening of Miami Church Road for traffic associated with new school
resulted in widening and extending the existing culvert. Since this area was not within the initial project scope, the beginning of
an intermittent stream was impacted by the culvert and rip rap dissapation pad. The culvert and outfall are within a legal
easement ROW secured by Cabarrus County. Although not directly abutting the "main school site", it still is connected to the
school site through the road widening requirement.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Cabarrus County Schools planned school buildings, parking and fields to avoid all jurisdiciontal features on "main school site".

' Boxes checked below shall be supported by completing the appropriate sections in Section III below.
z For purposes of this form, an RPW is defined as a tributary that is not a TNW and that typically flows year-round or has continuous flow at least "seasonally"
(e.g., typically 3 months).
' Supporting documentation is presented in Section III.F.
SECTION III: CWA ANALYSIS
A. TNWs AND WETLANDS ADJACENT TO TNWs
The agencies will assert jurisdiction over TNWs and wetlands adjacent to TNWs. If the aquatic resource is a TNW, complete
Section III.A.1 and Section IH.D.1. only; if the aquatic resource is a wetland adjacent to a TNW, complete Sections HI.A.1 and 2
and Section III.D.1.; otherwise, see Section III.B below.
1. TNW
Identify TNW:
Summarize rationale supporting determination:
2. Wetland adjacent to TNW
Summarize rationale supporting conclusion that wetland is "adjacent":
B. CHARACTERISTICS OF TRIBUTARY (THAT IS NOT A TNW) AND ITS ADJACENT WETLANDS (IF ANY):
This section summarizes information regarding characteristics of the tributary and its adjacent wetlands, if any, and it helps
determine whether or not the standards for jurisdiction established under Rapanos have been met.
The agencies will assert jurisdiction over non-navigable tributaries of TNWs where the tributaries are "relatively permanent
waters" (RPWs), i.e. tributaries that typically flow year-round or have continuous flow at least seasonally (e.g., typically 3
months). A wetland that directly abuts an RPW is also jurisdictional. If the aquatic resource is not a TNW, but has year-round
(perennial) flow, skip to Section III.D.2. If the aquatic resource is a wetland directly abutting a tributary with perennial flow,
skip to Section III.D.4.
A wetland that is adjacent to but that does not directly abut an RPW requires a significant nexus evaluation. Corps districts and
EPA regions will include in the record any available information that documents the existence of a significant nexus between a
relatively permanent tributary that is not perennial (and its adjacent wetlands if any) and a traditional navigable water, even
though a significant nexus finding is not required as a matter of law.
If the waterbody' is not an RPW, or a wetland directly abutting an RPW, a JD will require additional data to determine if the
waterbody has a significant nexus with a TNW. If the tributary has adjacent wetlands, the significant nexus evaluation must
consider the tributary in combination with all of its adjacent wetlands. This significant nexus evaluation that combines, for
analytical purposes, the tributary and all of its adjacent wetlands is used whether the review area identified in the JD request is
the tributary, or its adjacent wetlands, or both. If the JD covers a tributary with adjacent wetlands, complete Section IH.B.1 for
the tributary, Section III.B.2 for any onsite wetlands, and Section III.B.3 for all wetlands adjacent to that tributary, both onsite
and offsite. The determination whether a significant nexus exists is determined in Section H LC below.

Summarize overall biological, chemical and physical functions being performed:
C. SIGNIFICANT NEXUS DETERMINATION
A significant nexus analysis will assess the flow characteristics and functions of the tributary itself and the functions performed
by any wetlands adjacent to the tributary to determine if they significantly affect the chemical, physical, and biological integrity
of a TNW. For each of the following situations, a significant nexus exists if the tributary, in combination with all of its adjacent
wetlands, has more than a speculative or insubstantial effect on the chemical, physical and/or biological integrity of a TNW.
Considerations when evaluating significant nexus include, but are not limited to the volume, duration, and frequency of the flow
of water in the tributary and its proximity to a TNW, and the functions performed by the tributary and all its adjacent
wetlands. It is not appropriate to determine significant nexus based solely on any specific threshold of distance (e.g. between a
tributary and its adjacent wetland or between a tributary and the TNW). Similarly, the fact an adjacent wetland lies within or
outside of a floodplain is not solely determinative of significant nexus.
Draw connections between the features documented and the effects on the TNW, as identified in the Rapanos Guidance and
discussed in the Instructional Guidebook. Factors to consider include, for example:
• Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to carry pollutants or flood waters to
TNWs, or to reduce the amount of pollutants or flood waters reaching a TNW?
• Does the tributary, in combination with its adjacent wetlands (if any), provide habitat and lifecycle support functions for fish and
other species, such as feeding, nesting, spawning, or rearing young for species that are present in the TNW?
• Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to transfer nutrients and organic carbon that
support downstream foodwebs?
• Does the tributary, in combination with its adjacent wetlands (if any), have other relationships to the physical, chemical, or
biological integrity of the TNW?
Note: the above list of considerations is not inclusive and other functions observed or known to occur should be documented
below:

findings of presence or absence of significant nexus below, based on the tributary itself, then go to Section III.D:

Instructions for completion of worksheet (located on page 2): Begin by determining the most appropriate ecoregion based on
location, terrain, vegetation, stream classification, etc. Every characteristic must be scored using the same ecoregion. Assign points
to each characteristic within the range shown for the ecoregion. Page 3 provides a brief description of how to review the
characteristics identified in the worksheet. Scores should reflect an overall assessment of the stream reach under evaluation. If a
characteristic cannot be evaluated due to site or weather conditions, enter 0 in the scoring box and provide an explanation in the
comment section. Where there are obvious changes in the character of a stream under review (e.g., the stream flows from a pasture
into a forest), the stream may be divided into smaller reaches that display more continuity, and a separate form used to evaluate each
reach. The total score assigned to a stream reach must range between 0 and 100, with a score of 100 representing a stream of the
highest quality.

Dee Freeman
Secretary
June 25, 2010
Cabarrus County, NC
Dear Mr. Masters:
On June 2 and June 7, 2010, Polly Lespinasse of the Division of Water Quality (DWQ) conducted' a
compliance inspection in response to a complaint regarding the lack of erosion control measures associated
with construction activities at the above referenced site. The compliance inspection is associated with the
NPDES Construction Stormwater Permit, NCGO10000, issued to you on March 31, 2009.
The following impacts were observed during the site inspection:
• Stream impacts to an unnamed tributary to Hamby Branch (Class C Waters of the State) associated
with the stormwater discharge from a sediment basin located parallel to Miami Church Road.
Approximately 2-3" of sediment was observed in the stream for an approximate distance of 250 linear
feet.
• Sediment discharges from a sediment pond located along Abilene Road were observed off-site, to the
north of the property. The sediment paths were observed from the outfall of the sediment basin to the
off-site isolated pond north of the property and to the floodplain of a separate unnamed tributary to
Hamby Branch. Turbid water was observed in the off-site pond.
The culvert under Miami Church Road has been extended and riprap installed at the outlet of the
existing culvert extension. It also appears that the stream has been overwidened in this location to
accommodate the culvert extension. No permit from either the U.S. Army Corps of Engineers or DWQ
was available to determine if this activity was authorized.

• Various erosion control measures were either not installed or not properly maintained leading to the
discharge of sediment off-site and to jurisdictional resources. Examples include, but are not limited to,
direct discharges off-site from sediment basins, failed silt fences, and lack of erosion control measures
associated with improvements to Miami Church Road.
As a result of the site inspection, the following violations, detailed below, are noted:
Item I. Removal of Best Usage
The culvert extension, installation of riprap and overwidening of the unnamed tributary to Hamby
Branch represent non-compliance with 15A NCAC 028.0211(2) - 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 ll. Water Quality Standards
Discharge of turbid waters from the sediment basin to the off-site pond represents non-compliance with
15A NCAC 2B.0211(3)k, turbidity standards.
Item III. Other Waste
Sediment in the stream represents a violation of 15A NCAC 2B.0211(3) f - Oils; deleterious
substances; colored or other wastes: only such amounts as shall not render the waters injurious to the
public health, secondary recreation or to aquatic life and wildlife or adversely affect the palatability of
fish, aesthetic quatity, or impair the waters for any designated uses.
Item IV. NPDES Construction Stormwater Permit Conditions
Failure to install erosion control measures represents a violation of the NPDES Construction
Stormwater Permit, NCG010000, specifically Part I, Section A, Condition #2.
Failure to maintain the erosion control measures that have been installed represents a violation of the
NPDES Construction Stormwater Permit, NCG010000, specifically Part I, Section C, Condition #2.
Requested Response
This Office requests that you respond to this letter in writing within 30 days of receipt of this Notice. Your
response should be sent to both this Office at the letterhead address and to the attention of Mr. John
Hennessy at the Wetlands and Stormwater Branch, NPS Assistance and Compliance Oversight Unit, 1617
Mail Service Center, Raleigh, NC 27699-1617. Your response should address the following items:
1. Provide information on how you plan to prevent turbid water discharges to the off-site pond from the
construction site. This shall include information on measures to be taken to ensure that erosion control
measures are properly installed and maintained designed/required.
2. At this time, DWQ will not require the removal of the sediment in the unnamed tributary to Hamby Branch.
However, you must provide information on how you plan to prevent further sediment from leaving the site
and impacting the stream: Also, please be advised that additional sediment discharge to this stream from
your site will require the submittal and implementation of stream restoration plan.
Mr. Sam Masters
Page Three
3. If stream impacts to the unnamed tributary to Hamby Branch on Miami Church Road are to remain in place,
you must contact the U.S. Army Corps of Engineers (USACE) for information on the type(s) of permit
required. Depending on the type of permits'the USACE requires, application for a 401 Water Quality
Certification will also be required. If the proper permit(s) was obtained, from either the USACE or DWQ,
please provide a copy to DWQ. Please note that sediment impacts to streams can not be permitted.
4. The culvert extension and installation of the riprap have altered the dimension of the stream. Provide an
explanation of how you plan to restore the natural stream dimension in this location.
5. An explanation of how you plan to prevent further unauthorized impacts from occurring.
6. Erosion control measures must be properly installed and maintained as indicated in the approved Erosion
Control Plan. Contact the Division of Land Resources, Mooresville Regional Office, to schedule an
inspection which subsequently demonstrates compliance with the approved Erosion Control Plan.
7. Provide a detailed schedule with dates explaining when the restoration activities noted above will begin and
the projected completion date.
In addition, this Office may consider issuing a Notice of Violation (NOV) and Recommendation for Enforcement
to the Director of the Division of Water Quality regarding these issues and any future/continued violations that
may be encountered. Your above-mentioned response to this correspondence will be considered in this
process. This office requires that the violations, as detailed above, be abated immediately.
These violations and any future violations are subject to a civil penalty assessment of up to $25,000.00 per day
for each violation. Should you have any questions regarding these matters, please contact myself or Polly
Lespinasse at [phone]. Thank you for your attention to this matter.
Sincerely,
.-L !3 41-----

Dr. Mr. Krebs:
In response to the NOV document that was received in our office on Jun 28, 2010 Cabarrus
County Schools hired Concord Engineering & Surveying, Inc. and their sub-consultant, Brandon
Fulton, Carolina Environmental Consultants, Inc., P.A. to assist us in addressing NCDENR's
concerns regarding the under-road culvert that was installed under Miami Church Road near our
new school site. Our general contractor, Matthews Construction also retained the services of
Estes Design, Inc. to assist them with portions of the NOV that dealt specifically with erosion
control issues.
Ms. Polly Lespinasse, an Environmental Specialist with your office, met with me and
representatives of all the consulting firms that have been employed by us at the site.
Ms. Lespinasse reviewed the corrective work that had been done to date and also discussed
the actions needed to mitigate the problems with the outflow from the culvert.
Attached are the reports from our consultants in answer to the individual items identified in the
NOV as well as photographs taken by Estes Design of the recent improvements that were made
to the erosion control measures on the site to address NCDENR's concerns.
Also included in this information is a detail of the proposed modifications to the culvert outfall
area that was prepared and submitted to Ms. Lespinasse for her review by Jay Eaves with
Concord Engineering and Surveying, Inc. Ms. Lespinasse approved the detail and the work on
this outfall area was completed this morning by our site contractor. I believe that the work was
reviewed and accepted by Ms. Lespinasse.
Overall, I want to assure you that once we received the NOV from your office, Cabarrus County
Schools took things very seriously and reacted as quickly as possible with the assistance of our
consultants, the contractor, and Ms. Lespinasse. We appreciate your help in bringing these
matters to our attention and trust that our timely response to these matters, as presented in the

Re: Notice of Violation/Recommendation For Enforcement-Response
NOV-2010-PC-0712
AT Allen Elementary School, 3939 Abilene Road
Cabarrus County, NC
Mr. Witke:
The purpose of this correspondence is with regard to the Notice of Violation and
Recommendation of Enforcement (NOV) received by Cabarrus County Schools dated
June 25, 2010. This document was in response to compliance inspections made by the
North Carolina Division of Water Quality (NC DWQ) after complaints of offsite
sedimentation due to inadequate erosion control measures and/or maintenance of those
apparatus' during construction activities for the newly constructed AT Allen replacement
School. During site inspection, NC DWQ identified a culvert located offsite of the main
school construction site that had been altered to support the widening of Miami Church
Road. Miami Church road was widened to accommodate additional influx of traffic
associated with the new school. Although offsite of the main school construction site, this
culvert extension occurs in an easement provided to Cabarrus County Schools, and is the
organization that is financially responsible. Since the culvert was not initially part of the
original scope of the school construction, the culvert was altered without determination of
the channels' jurisdictional status. After further review from NC DWQ, it was determined
that an intermittent steam originated at the southern outlet of the previous culvert. The
new culvert and rip rap out fall extend approximately 60 feet beyond the end of the
previous culvert end point. Therefore an impact to a jurisdictional stream was completed
1
without notification to the United States Army Corps of Engineers (USAGE) or NC
DWQ.
Carolina Environmental Consultants (CEC) visited the site on July 20, 2010 at the request
of Mr. Jay Eaves, PE of Concord Engineering and Surveying Inc. (CESI). CEC was
contracted as a third party environmental consultant through CESI for Cabarrus County
Schools for the purpose of resolving NOV violations associated with the culvert
extension under Miami Church Road.
CEC visited the CESI office on July 20, 2010 to conduct a background file review for the
site. After review it was determined that no Jurisdictional Determination or stream impact
permits existed for the easement location containing the extended culvert under Miami
Church Road.
CEC visited the site on July 21, 2010 to perform an evaluation of the channel originating
from the culvert. After performing NC DWQ stream identification forms on the channel,
and after taking note of hydrologic and soil conditions, CEC determined that the channel
was intermittent in nature.
CEC contacted Polly Lespinasse July 21, 2010 with the NC DWQ who confirmed CEC's
finding that stream is intermittent at the culvert outlet. Due to altered site conditions, the
state has deemed the intermittent stream origin to be at the location of the outlet for the
previous culvert. Total impact amounts for the stream will include the length of the
culvert extension plus the rip rap outfall area. Impacts total approximately 60 linear feet.
CEC is in the process of coordinating with the USACE and the NC DWQ to obtain a
formal Jurisdictional Determination from the USACE, and to obtain the required 404 and
401 After the Fact permitting from the USACE and NC DWQ respectively.
Upon receipt of the NOV by Cabarrus County Schools, Matthews Construction Company
retained Estes Design Inc. to strategically plan and mitigate items identified in the NOV
not related to the culvert extension. According to the letter from Estes Design Inc. dated
July 21, 2010 to Matthews Construction Company, the site was secure and remediation
efforts had addressed the impacts noted in the NOV as of July 13, 2010. Please see the
aforementioned correspondence attached.
Responses to the NOV letter are numerically listed in order per the NOV. Responses are
italicized. Responses 1, 2, 6 and 7 are specific to Matthews Construction and Estes
Design Inc. and are an attachment to this report. Responses 3, 4 and 5 (see below)
2
pertain to the culvert extension and are being addressed by CESI and CEC
respectively.
3. If stream impacts to the un-named tributary to Hamby Branch on Miami Church Road
are to remain in place, you must contact the USACE for information on the type(s) of
permits required. Depending to the type of permits the USACE requires, application for a
401 Water Quality Certification will also be required. If the proper permit(s) was
obtained from either the USACE or DWQ, please provide a copy to DWQ. Please note
that sediment impacts to streams cannot be permitted.
(CEC response) CEC has contacted both the USACE and NC DWQ concerning the
stream. Both NC DWQ and the USACE have agreed that the stream is intermittent and
unimportant respectively. Supporting information is currently being compiled and will be
provided to the USA CE to obtain a.formal Jurisdictional Determination (JD) that will be
an addendum to the previous JD (SAW-2008-3091) obtained by CESI December 2, 2008
for the main school site. CEC will also provide to the USACE and NC DWQ a Pre-
Construction Notification (PCN) that will be deemed an After the Fact permit. USACE
permitting will be considered under a Nation Wide Permit #14 (Linear Transportation
Projects) and a General Certification #3820 for NC DWQ. Anticipated submission for
permit applications is before July 30, 2010.
4. The culvert extension and installation of the riprap have altered the dimension of the
stream. Provide an explanation of how you plan to restore the natural stream dimension
in this location.
(CEC response) CEC and CESI will coordinate work to be completed to restore altered
dimensions of the stream bank affected by the culvert outfall. After the site meeting with
DWQ representative Polly Lespinasse on July 20, 2010, it was agreed that the banks
would be amended to pre-construction configuration with supportive media strategically
placed to support the banks until adequate vegetation has been established. This work
will be closely monitored during construction activities by CEC and CESI to ensure no
additional sediment releases take place during the restoration of the banks. Please see
attached drawing frrom CESI Engineer Mr. Jay Eaves that illustrates sizing and slope
percentages to be constructed. Work is scheduled to begin 7-28-2010. NC DWQ will be
notified during and after construction to review site activities.
3
5. An explanation of how you plan to prevent further unauthorized impacts from
occurring.
(CEC response) Cabarrus Count), Schools does not have any additional proposed
impacts at this time. All site activities have been completed on the main school site, with
specific regard given to avoiding all jurisdictional features on the main school site
during initial construction. The culvert under Miami Church Road has already been
altered and road widening activities have been completed. Cabarrus County Schools will
make sure in the.future to notify CESI and CEC if any additional construction activities
are to take place. This will enable CESI and CEC to peiform due diligence into any
potential impacts to jurisdictional or state regulated waters or features. Additionally,
construction activities to take place adjacent to the intermittent stream and culvert under
Miami. Church Road will be closely monitored and the NC DWQ will be provided
complete detail of project duration and success. All other sediment and erosion control
devices onsite will be monitored through Matthews Construction Inc. and associated
consultants' monitoring responsibilities.
CEC is glad to be of service to you in this matter. Please contact me directly if you have
any questions regarding this report or other environmental concerns.

Subject: Notice of Violation / Recommendation for Enforcement - AT Allen Elementary
Dear Mr. Sigmon,
On June 27"' 2010 Cabarrus County Schools received a written Notice of Violation and Recommendation
for Enforcement due to inadequate erosion control treasures and extension of a culvert under Miami
Church Rd. The culvert under Miami Church Rd. was extended without proper authorization fi-om the US
Army Corps of Engineers and NC Department of Environment and Natural Resources.
As the responsible contractor on site you contacted and retained Estes Design Oil June 30, 2010 to
represent Matthews Construction Company as it's mitigating Environmental Consultant. Mr. Estes of
Estes Design met with you July 1, 2010 and reviewed the plans and the on-site erosion control measures
with the grading subcontractor. All of the impacts noted in the NOV were reviewed and discussed. Estes
Design communicated the required actions to be taken in order to bring the site into compliance.
On July 1 2010, Estes Design contacted the offices of NCDENR and spoke with Mr. Michael Burkhard.
Estes communicated that Matthews Construction had retained Estes Design as their Environmental
Consultant in order to mitigate and respond to the NOV. This communication was passed on to Ms. Polly
Lespinasse of NCDENR.
On July 8 2010, Ms Polly Lespinasse contacted Estes Design to briefly discuss the issues. Estes Design
then contacted The US Army Corps of Engineers to determine if any authorizations had been issued to
Cabarrus County Schools for AT Allen Elementary. No records exist.
Matthews Construction started remediation of the erosion control measures before our site meeting on
July 1. Estes Design followed tip with subsequent site visits on July 8'h, 13"' & 20"'. As of July 13"' the
site was secure and remediation efforts had addressed the impacts noted in the June 25"' NOV letter with
exception of the culvert extension under Miami Church Rd.
On June 20 2010, Mr. Estes, Steve Sigmon, Robert Tripp and William Connelle met to discuss (lie
requirements to address the culvert extension impacts as noted in the NOV. It was noted that typically a
third party environmental consultant responds to the NOV in its entirety. This expedites the process and
reduces confusion. After discussing the requirements of obtaining an After The Fact Permit Mr. Connelle
asked that a proposal for these services be submitted as soon as possible. Immediately following the
conclusion of this meeting, Matthews Construction and Estes Design learned that a second meeting had
been scheduled on site with Mrs. Lespinasse of NCDENR, Jay Eaves of Concord Engineering, Len Witke
of Cabarrus County Schools and William Connelle of Cabarrus County Schools.
During this second meeting the same issues were discussed concerning the unauthorized impacts of the
culvert extension under Miami Church Rd. and the need for an After The Fact Permit. At the end of this
meeting Mr. William Connelle verbally communicated that they would be retaining the original
environmental consultant, Mr. Jay Eaves, to respond to the Notice of Violation on behalf of Cabarrus
County Schools.

The unauthorized impacts caused by the culvert extension under Miami Church Rd. is not the
responsibility of Matthews Construction and is a separate planning and design responsibility of Cabarrus
County Schools. Estes Design did a preliminary review of existing information pertaining to the culvert
extension impacts and Jurisdictional waters. This preliminary information is attached as exhibits. More
.jurisdictional waters may be present on site than were shown on the attached wetland survey with notes.
The following responses pertain to Matthews Construction's Erosion Control and are numbered the same
as in the NOV letter:
1. Provide information on how you plan to prevent turbid water discharges to the off-site pond from
the construction site. This shall include information on measures to be taken to ensure that
erosion control measures are properly installed and maintained designed/required. Rip - Rap
and double silt fence has been installed and re-secured. Stormwater flow over the shoulder of
Abilene Rd, was contributing sediment to this area. The shoulder has been raised and stabilized.
No additional sediment has been observed passing the silt fence. However, it very likely that
after the site is stabilized sediment will continue entering the off-site pond, not fro?n the
construction site but from the existing off-site channel shown in exhibit 1-3. This will be due to
the increased volume of water flowing through the channel. This will most likely accelerate the
existing head-cut.
2. At this time. DWQ will not require the removal of the sediment in the unnamed tributary to
Hamby Branch. However, you must provide information on how you plan to prevent further
sediment from leaving the site and impacting the stream. Also, please be advised that additional
sediment discharge to this stream from your site will require the submittal and implementation of
a stream restoration plan. Five rows of silt fence and additional rip-rap have been installed. No
additional sediment has been observed passing the silt fences. See exhibit 3. Large storms will
and have caused the silt fence posts to bend. This area will be monitored and maintained closely.
Additional rip-rap has also been installed at the inlet end to resist erosion. See exhibit 4.
6. Erosion control measures must be properly installed and maintained as indicated in the approved
Erosion Control Plan. Contact the Division of Land Resources, Mooresville Regional Office to
schedule an inspection which subsequently demonstrates compliance with the approved Erosion
Control Plan. Estes Design will coordinate and schedule an inspection after this letter has been
received by the offices of NCDENR,
7. Provide a detailed schedule with dates explaining when the restoration activities noted above will
begin and the projected completion date. The restoration activities that Matthews Construction is
responsible for were substantially complete on July 13 2010. Storm events will be monitored
closely and the measures maintained until the site has been stabilized with permanent ground
cover.
Please contact me with any questions you may have.

Important maintenance procedures:
- Immediately after the wet detention basin is established, the plants on the
vegetated shelf and perimeter of the basin should be watered twice weekly if
needed, until the plants become established (commonly six weeks).
- No portion of the wet detention pond should be fertilized after the first initial
fertilization that is required to establish the plants on the vegetated shelf.
- Stable groundcover should be maintained in the drainage area to reduce the
sediment load to the wet detention basin.
- If the basin must be drained for an emergency or to perform maintenance, the
flushing of sediment through the emergency drain should be minim zed to the
maximum extent practical.
- Once a year, a dam safety expert should inspect the embankment.
After the wet detention pond is established, it should be inspected once a month and
within 24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a
