Notice of Violation Response
USACE Action ID 200421124
NOV-2008-PC-0714
DWQ EXP #04-1672
Chatham County, NC
Dear Ms. Witherspoon and Mr. Smith:
As requested in your October 22, 2008 Notice of Violation (NOV), Soil & Environmental
Consultants, PA (S&EC) has been engaged by Crescent Resources to prepare a Sediment
Impact Delineation Report and Clean-up Plan for in-stream sedimentation which has
occurred within the referenced project site as well as a Stream Restoration Plan. In
addition, further discussions between S&EC, Crescent Resources, the US Army Corps of
Engineers and yourself has led to S&EC preparing this NOV response.
Within the October 22, 2008 NOV, the following violations were listed and identified:
1) 401 Water Quality Certification Condition Violation
2) Removal of Best Usage
3) Other Waste (In-stream sediment)
4) Stormwater General Permit - NCGO10000 Violation
The remainder of this letter will respond to each item individually; the original request
will be in italics followed by our response:
1. Documentation depicting all jurisdictional features (e.g. steams and wetlands). A
description and quantification of the impacts to those jurisdictional features and your
plans to avoid further stream and wetland area impacts on the site.
On February 1, 2005, Mr. Todd Tugwell, formerly with the USACE, issued a Notice
of Jurisdictional Determination (JD) for the jurisdictional streams and wetlands for
The Retreat on The Haw River
Soil & Environmental Consultants, PA
November 26, 2008
Project No. 6748.P1
the entire subject property (see Action ID 200421124). This JD does not expire until
February 1, 2010. The original permit requests in 2004 and subsequent approvals
called for 109 linear feet of permanent impact to unimportant/intermittent stream
channels and 194 liner feet of permanent impact to important/perennial stream
channels. These impact details were quantified and illustrated in the initial permit
submittal.
Field observations made by S&EC staff on September 23, 2008 are as follows:
Impact No. 1:
Permitted in 2005: 74 linear feet of permanent intermittent/unimportant channel
impact for road crossing (30" RCP) and 35 linear feet for rip rap pad (total 109 linear
feet of permanent intermittent/unimportant channel impact);
Observed in September 2008: 74 linear feet of permanent intermittent/unimportant
channel impact for road crossing (30" RCP) and 23 linear feet for rip rap pad (total 97
linear feet of permanent intermittent/unimportant channel impact); additional
temporary impact (not permitted) includes a check dam upstream of the crossing and
a collection of large rocks in the channel.
Impact No. 2:
Permitted in 2005: 60 linear feet of permanent perennial/important channel impact
for road crossing (60" RCP) and 40 linear feet for rip rap pad (total 100 linear feet of
permanent perennial/important channel impact);
Observed in September 2008: 40 linear feet of permanent perennial/important
channel impact for road crossing (60" RCP) and 56 linear feet of rip rap pad (total 96
linear feet of permanent perennial/important channel impact); additional temporary
impacts include approximately 6 linear feet of non-native rock immediately upstream
of the crossing as well as two pre-existing, failing corrugated black pipes.
Impact No. 3:
Permitted in 2005: No charnel impacts as a bottomless arch was proposed;
Observed in September 2008: No channel impacts were observed as the bottomless
arch was installed per the 2005 Approvals.
Impact No. 4:
Permitted in 2005: 94 linear feet of permanent perennial/important stream channel
impact for road crossing;
Observed in September 2008: No channel impacts were observed as a bridge was
built for this crossing instead of traditional culverts.
There are no additional impacts anticipated for this project.
2. Stream Restoration Plan-Please explain how you plan to restore the pattern, profile
and dimension of the impacted stream channels to include the removal of the
boulders from the stream, removal of the check dam and stabilization of the banks.
The streambed must be restored to the original profile and the stream banks must be
stabilized.

Project No. 6748.P 1
S&EC has been engaged by Crescent Resources to provide the NC DWQ and the
USACE with a Stream Restoration plan for the streams associated with Impact Nos.
and 2. This will include a stream restoration plan, removal of the check dam and
stream bank stabilization.
It should be noted that during the October 2, 2008 site visit, both the USACE and the
NC DWQ were in agreement that the check dam located upstream at Impact No. 1
should remain in place until the sediment basins are removed. It is not anticipated
that these temporary sediment basins will be removed from the project for at least
another year.
The Stream Restoration and Stabilization plan is currently being developed and will
be submitted to both the USACE and the NC DWQ for approval under separate cover
within the next 60 days. The Stream Restoration and Stabilization plan will include a
detailed implementation schedule and the necessary 3-year monitoring plan for the
restored stream channels.
3. Stream Clean Up Report (sediment impacts) - Sediment impacts to the stream must
be removed. It is recommended that you use hand labor (buckets, shovels and
wheelbarrows) to remove deposited sediment from the stream channel. The sediment
should be removed from the channel, taken to high ground away from the stream
channel and stabilized. Provide a report that describes the measures taken to remove
sediment deposition and include photos.
As discussed previously, S&EC has been engaged by Crescent Resources to develop
a Sediment Delineation and Removal report for the stream channels noted during the
October 2, 2008 site visit. On October 2, 2008 S&EC delineated the sediment found
at the locations noted during the site visit with DWQ and the USAGE, namely
Crossing No. 1 and the Williams Pond relic spillway. On October 14, 2008 S&EC
Personnel along with Eco Terra Landscape and Erosion Control, Inc completed the
sediment clean-up. The Sediment Clean-up Completion report was submitted to the
both the USACE and NC DWQ on October 22, 2008.
4. Permit Application - If you wish for any impacts to remain in place, you must contact
the U.S. Army Corps of Engineers (USA CE) and the DWQ to modify your 404 and
401 permits. Please note that sediment impacts to streams are not permittable.
S&EC has been engaged by Crescent Resources to prepare and submit a
Sedimentation Clean-up Plan as well as a Stream Restoration and Bank Stabilization
Plan. It is not the intent of the applicant, Crescent Resources, that any of the
unauthorized, temporary impacts to remain in place.

5. Please provide a statement documenting that the approved Erosion and Sedimentation
Control Plan is on-site and available for review. A rain gauge must be properly
installed as required by the permit. Please provide a statement documenting the
location of the rain gauge. Provide all rain gauge data collected to include the past
three months of monitoring through to the date of your written response to this letter.
If you do not have data, explain why. Explain the steps taken to ensure future
compliance with the Twenty-four Hour Reporting requirement.
The Erosion and Sedimentation Control Plans are on-site at the Phase One construction
entrance on Bynum Ridge Road and are available for review. There is also a rain gauge
located on the entrance gate post on the left side. We have attached the monitoring
reports from the past month provided by Mr. Fred Ward of the Chatham Land
Management group. Past monitoring and reporting was done by Glover Construction
Company, Inc. who supplied the reports and data to Crescent Resources (see attached
letter). At this time, Crescent Resources is unable to locate those reports. Mr. Fred Ward
of the Chatham Land Management group has been retained by Crescent Resources to
provide Erosion and Sedimentation Control monitoring and reporting for The Retreat on
the Haw River development site to ensure compliance with all aspects of the approved
Erosion and Sedimentation Control Plan.
We anticipate that this addresses all of the DWQ's concerns. If you have any further
questions or any additional explanation is needed, please don't hesitate to call.
Sincerely,
Nicole J. Thomson

Re: Retreat at Haw River
To Whom It May Concern:
Glover Construction Co., Inc. had our Superintendent (Eddie Miller) prepare (at a minimum) the weekly
monitoring records required to meet the NPDES Stormwater Discharge Permit for Construction Activities
(General Permit NCG010000) requirements which were part of the Chatham County Soil Erosion and
Sedimentation Control approval obtained for the project. The inspections were conducted beginning
approximately January 26, 2007 and ending approximately February 22, 2008. These reports were retained on
site during construction as required by the permit and provided to a Crescent representative upon demobilizing
from the site. We did not retain a copy here in the office.
If you have any questions, please call our office at [phone] or fax [phone].
Sincerely,
GLOVER CONSTRUCTION CO., INC.
