Dear Mr. Clark:
The Division of Water Quality has reviewed your submittal for a 401 Certification for the subject project. Your application
was not complete since the stormwater management plan is not sufficient to meet condition no. 3 in Water Quality
General Certification No. 3362.
Specifically, the above condition requires stormwater management facilities for waters classified as NSW and that are
considered to remove 85% TSS. Based on the plans provided with the application only roughly half of the impervious
areas of the site would meet this requirement by the use of bioretention areas. As such, it will be necessary to provide
similar treatment for the rest of the impervious area at the site. Please note that these requirements may be in addition to
those required as part of Cary's nutrient reduction strategy. This information is needed by DWQ in order for us to decide
whether this project is approvable.
Please contact Todd St. John at 919-733-9584 if you have any questions. Until this information is received, I will place
this project on hold due to incomplete information (15A NCAC 2H .0507(a)).
Sincerely,

DWQ# 021162
The applicant only proposed stormwater for about 1/2 of the site. The applicant did not provide
adequate stormwater treatment for about 1.9 acres of impervious cover as required by condition 3 in
GC 3362. Sean Clark wants to set up a meeting with me to resolve this matter.
The applicant provided some level spreaders (which may not work due to slope as you
suggested), some intermittently placed bioretention (and some dry detention w/o level spreaders). In
the final analysis, the applicant did not provide 85% TSS stormwater treatment facilities appropriate
for NSW waters for all of the impervious cover on the site.

February 28, 2003. After reviewing your application, we have decided that this fill is covered by General Water Quality
Certification Number 3362. This certification allows you to use Nationwide Permit Number 39 when the Corps of
Engineers issues it. This approval is also valid for the Neuse River buffer rules (15A NCAC 2B .033). In addition, you
should get any other federal, state or local permits before you go ahead with your project including (but not limited to)
Sediment and Erosion Control, Coastal Stormwater, Non-Discharge and Water Supply Watershed regulations. This
approval will expire when the accompanying 404 or CAMA permit expires unless otherwise specified in the
General Certification.
This approval is only valid for the purpose and design that you described in your application except as modified
below. If you change your project, you must notify us and you may be required to send us a new application. If
the property is sold, the new owner must be given a copy of this Certification and approval letter and is thereby
responsible for complying with all conditions. If total wetland fills for this project (now or in the future) exceed
one acre, compensatory mitigation may be required as described in 15A NCAC 211.0506 (h) (6) and (7). This
approval shall expire when the corresponding Nationwide Permit expires or as otherwise provided in the General
Certification. For this approval to be valid, you must follow the conditions listed in the attached certification and
any additional conditions listed below. Deed notifications or similar mechanisms shall be placed on all remaining
jurisdictional wetlands and waters to notify the state in order to assure compliance for future wetland and/or water
impact. These mechanisms shall be put in place within 30 days of the date of this letter or the issuance of the 404
Permit (whichever is later).
An additional condition is that a final written stormwater management plan shall be approved
in writing by this Office before the impacts specified in this Certification occur. The
bioretention areas and pocket wetlands must be constructed according to the plans submitted to
this Office on February 28, 2003 according to the timeline below with the exception that the
bioretention area labeled YI#4 shall be redesigned as an extended detention wetland with the
same surface area as the bioretention area. The extended detention wetland must include plans
and specifications for stormwater management facilities designed to remove 85% TSS
according to the most recent version of the NC DENR Stormwater Best Management Practices
Manual. All of these facilities must be designed to treat the runoff from the entire project, unless

OPERATIONS AND MAINTENANCE MANUAL
SALEM CASTLE WATERSHED PROTECTION BIO-RETENTION AREAS
This manual establishes procedures for maintenance and operation of the SALEM CASTLE
Bio-retention areas in accordance with the Town of Cary guidelines as set forth in the UDO
Section 10, Chapter 13.
MAINTENANCE OF 13110-RETENTION AREAS
Vegetation-The drainage areas have a ground cover of fescue, which if properly maintained
will prevent erosion of the embankment and provide an easy surface for inspection. The grass
will be most difficult to obtain in the area subject to water level fluctuation. Grass should be
fertilized every October and April.
Re-Seeding-Periodic re-seeding may be required to establish grass on areas where seed did
not take or have been destroyed. Before seeding, fertilizer (12-12-12) should be applied at a
minimum rate of 12 to 15 pounds per 1,000 SF. The seed should be evenly sown at a rate of
three pounds per 1,000 SF. The seed should be covered with soil to the depth of approximately
%". Immediately following the planting, the area should be mulched with straw.
Trees and Shrubs-Trees, shrubs and other landscape vegetation should be permitted only as
shown on the approved planting plan. The vegetation should be kept healthy and vibrant. If a
tree or shrub dies it should be removed and replaced with another tree or shrub from the same
species (see attached maintenance schedule).
Mowing-Grass mowing, brush cutting and removal of weed vegetation will be necessary for
the proper maintenance of the areas. All area slopes and vegetation should be mowed when
the grass exceeds 8" in height. Acceptable methods include the use of weed whips or power
brush cutters and mowers.
Erosion-Erosion occurs when the water concentrates causing failure of the vegetation or
when vegetation dies and sets up the environment for rill erosion and eventually gullies from the
stormwater runoff. The areas should be inspected. Proper care of vegetative areas that
develop erosion is required to prevent more serious damage to the site. Rills and gullies should
be filled with suitable soil compacted and then seeded. Methods described earlier on vegetation
should be used to properly establish the grass surface. Where eroded areas are detected, the
cause of the erosion should be addressed to prevent a continued maintenance problem.
Frequently, problems result from the concentration of runoff to one point of the bio-retention
area instead of a uniform distribution of runoff. This can be corrected by reshaping, to more
evenly distribute the runoff to areas not experiencing erosion problems.
Rodent Control-Generally in this urban environment, rodents are not a problem. Rodents
such as groundhogs, muskrats and moles are attracted to moist, wet areas and can be quite
dangerous to structural integrity and proper performance of the earthwork and drainage.
Groundhogs and muskrats thrive on burrowing into the manmade earthwork, which become
pathways for seepage. In the event that burrows are detected within the bio-retention area, the
rodents should be dealt with by removal.
Trash and Debris--Trash acts as a barrier to stormwater infiltration and attracts unwanted
pests. The bio-retention area should be kept clear of debris such as loose bottles, cans, food
containers and other forms of rubbish. The area should be cleared of debris as needed, but no
less than twice a year.
MAINTENANCE OF SPILLWAYS AND CONTROL STRUCTURE
Inspection of Conduits--Conduits should be inspected thoroughly once a year. Conduits
should be visually inspected at the joints. Pipes should be inspected for proper alignment
(sagging), elongation and displacement at joints, cracks, leaks, surface wear, loss of protective
coating, corrosion and blocking. Problems with conduits most often occur at joints and special
attention should be given to them during inspection. Joints should be checked for gaps caused
by elongation or settlement and loss of joint filler material. Open joints can permit erosion of the
earthwork and possibly the piping of soil material through the joints. A depression in the soil
surface over the pipe may be signs that soil is being removed from around the pipe.
OPERATION
Drainpipes--Drainpipes should always be operable so that the water can be drawn down in the
event of severe rain or for repairs or maintenance.
Record Keeping--Operation of bio-retention area should include recording of the following:
Annual Inspection Reports--A collection of written inspection reports should be kept on
record in Section IV of this manual. Inspection should be conducted annually. Copies
should be provided to the Town of Cary Stormwater Management Section of the
Engineering Department.
Observations--All observations should be recorded. Where periodic inspections are
performed following significant rainfall, these inspections should be logged into the
Periodic Inspection, Operations and Maintenance Form in Section IV of this manual.
Maintenance--Written records of maintenance and/or repairs should be recorded on the
Periodic Inspection, Operation and Maintenance Form in Section IV of this manual.
Other Operational Procedures--The owner should maintain a complete and up-to-date set of
plans (as-built drawings) and all changes made to the bio-retention area over time should be
recorded on the as-builts.
Sedimentation and Dredging--Sedimentation from on-site and off-site soils will eventually result
in the clogging of drainage conduits and will have to be removed. The frequency of this
sediment removal can be reduced by ensuring that the site areas around the building be
stabilized with a vegetative ground cover such that it restrains erosion. This would include a
periodic application of fertilizer and/or other treatment necessary to promote a stable ground
cover and minimize sedimentation to the pond. The removed material should be hauled offsite
to a suitable landfill site or mounded somewhere on site and stabilized with a ground cover
sufficient to restrain erosion.

b. Check and clear the orifice of any obstructions such that drawdown of the temporary pool occurs within
2 to 5 days as designed.
2. Repair eroded areas immediately, re-seed as necessary to maintain good vegetative cover, mow
vegetative cover to maintain a maximum height of six inches, and remove trash as needed.
3. Inspect and repair the collection system (i.e. catch basins, piping, swales, riprap, etc.) quarterly to
maintain proper functioning.
4. Remove accumulated sediment from the stormwater pocket wetland detention basin system semi-
annually or when depth is reduced to 75% of the original design depth (see diagram below). Removed
sediment shall be disposed of in an appropriate manner and shall be handled in a manner that will not
adversely impact water quality (i.e. stockpiling near the stormwater pocket wetland detention basin, bio-
retention basin, stream, etc.).
The measuring device used to determine the sediment elevation shall be such that it will give an accurate
depth reading and not readily penetrate into accumulated sediments.
When the permanent pool depth reads 474.27 feet in the forebay [and micro-pool], the sediment shall be
removed. If the elevation of the adjoining marsh areas exceeds the permanent pool elevation, the
sediment should be removed to design levels. This shall be performed by removing the upper 6 inches of
soil and stockpiling it. Then the marsh area shall be excavated six inches below design elevations.
Afterwards the stockpiled soil should be spread over the marsh surface. The soil should not be stockpiled
for more than two weeks.

5. Remove cattails and other indigenous wetland plants when they cover 50% of the basin surface. These
plants shall be encouraged to grow along the vegetated shelf and forebay berm.

Wetland planting densities in the marsh areas should be maintained by replanting bare areas as needed.
Wetland plants should be encouraged to grow in the marsh areas.
6. If the basin must be drained for an emergency or to perform maintenance, the flushing of sediment
through the emergency drain shall be minimized to the maximum extent practical.
7. All components of the stormwater pocket wetland detention basin system shall be maintained in good
working order.
8. Level spreaders or other structures that provide diffuse flow shall be maintained every six months. All
accumulated sediment and debris shall be removed from the structure, and a level elevation shall be
maintained across the entire flow spreading structure. Any down gradient erosion must be repaired
and/or replanted as necessary.
I acknowledge and agree by my signature below that I am responsible for the performance of the seven
maintenance procedures listed above. I agree to notify DWQ of any problems with the system or prior to any
changes to the system or responsible party.

RE: Request for Nationwide Permits 18 and 39, 401 Water Quality
Certification, and Neuse Buffer Compliance for the proposed Salem
Castle Site in Cary, Wake County, NC (Zone 1. 7, 7030001" E, 3962660m N)
Dear Mr. Dorney and Ms. Jones:
On behalf of Salem Castle, Inc. (property owner), we hereby request
authorization from the US Army Corps of Engineers (USAGE) to use
Nationwide Permits 18 (Impacts 1 and 2) and 39 (impact 3) for proposed
impacts to jurisdictional. wetlands resulting from the construction of a
commercial facility for the above referenced project. We also request 401-
certification and written concurrence from the NC-Division of Water Quality
(DWQ) that the proposed project complies with the Neuse River Riparian.
Buffer Rules. A Pre-construction Notification Application (PCN) is
attached, as is an agent authorization form.
The proposed project is located immediately south of East Chatham Street
(SR 1011) approximately 2500 feet east of the intersection of SR 101.1 and
Maynard Road (SR 1415) in Cagy, Wake County, North Carolina. The
proposed site is approximately 8 acres in size. It contains a jurisdictional
channel that bisects the property. The channel starts below the dam of a
drained pond on-site. Mr. Steve Mitchell of DWQ confirmed that the
buffers began below the dam on October 11, 2000. A copy of Mr.
Mitchell's December 20, 2000 letter (NBRRO 00-326) is attached. The
site's jurisdictional determination was made on July 20, 2001 (Action ID
#199821091) by Ms. Amanda Jones of the USACE.

VII. Impact Justification (Avoidance and Minuirlulzation)
Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts.
Due to the size of the property and the location of the buffered stream channel, there
alternatives considering the size and t c of the desired r Ject. Previous plans pro osed. a road
crossing of the bufl;'ered c_hanncl requested by the Town of Cary This road crossinL would have
impacted buffers stream channel_ and an additional riparian wetland. Thrgwh negotYations with

been avoided com
VIII. Mitigation
DWQ - In accordance with 15A NC,A.C 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
permits, published in the Federal Register on March 9, 2000, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached. in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as
incomplete. An applicant may also choose to review the current guidelines for stream restoration
in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at
http;//h2o enr state nc us/ncwctlands/strmgi q.-btml.
1. Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to, site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
Pavrnent to the NC WRP is prooosed for required wetland mitigation. No buffer or
stream mitigation is_provosed nor should it be rcauired because there are no_pML sed.
impacts to Neuse River Buffers or streams.

Re: Salem Castle
DWQ# 021162
Wake County
I reviewed this project and the applicant has now proposed adequate stormwater BMPs. The applicant agreed to building
an extended detention wetland as opposed to a bioretention area at YI #4 (the large basin area on the north side of the
stream). This structure would be adequately sized to treat the entire drainage area draining to it. The bioretention areas in
series with it would be bonus. The only problem is that the bioretention area (DA - 0.3 ac) adjacent to the tilt yard (the
oval shaped structure on the east side of the project) is 20% too small. Its size is maximized. In any event considering the
amount of bonus treatment that we would be getting (even at this location), I recommend that we approve it as is. Here's
some lingo:
An additional condition is that a final, written stormwater management plan shall be approved in writing by this Office
before the impacts specified in this Certification occur. The bioretenion areas and pocket wetlands will be constructed
according to the plans submitted to this Office on February 28, 2003 according to the timeline belowwith'the exception
that the bioretention area labeled YI #4 shall be redesigned as an extended detention wetland with the:same surface area
as the bioretention area. The extended detention wetland must include plans and specifications-for stormwater
management facilities designed to remove 85% TSS according to the most recent version of the.NC DENR Stormwater
Best Management Practices Manual. All of the above facilities must be designed to treat the runoff froli1he entire project,
unless otherwise explicitly approved by the Division of Water Quality. Also, before any permanent building is occupied at

Re: Information requested in the November 1, 2002 letter and the
November 20, 2002 office meeting in reference to the proposed
Salem Castle Site, Cary, Wake County, North Carolina
Dear Mr. Dorney:
This letter will provide the information you requested in the
November 1, 2002 letter (see attached copy) in the order in which the
questions were asked.
1. The attached sheets of the proposed site plan (SITE 201, SITE
202, and SITE 203) show the location of the structure to be
outside of Zone 2 of the Neuse River Buffers.
2. Please find attached the calculations for the stormwater
detention areas as requested. The stormwater being dispersed
under the road crossing will be treated in a series of bio-
retention areas in the parking lot (see maps) and will then enter
Zone 2 as sheet flow after passing below the road. Stormwater
from the building will be discharged to the west of the building as
shown on the SITE 201 map and will enter Zone 2 as sheet flow.
3. The shape of the buffer in the location that you specify is due to
a couple of large bends in the stream. The SITE 201 map
depicts the location of the stream channel as shown on the
surveyed USACE approved delineation map.

Re: Information requested in the August 22, 2002 office meeting in reference to the
proposed Salem Castle Site, Cary, Wake County, North Carolina
Dear Mr. Dorney:
An earlier response sent to you on August 16, 2002 should have answered questions
and provided the additional information requested in your July 30, 2002 letter. This letter
will provide the information you requested in the August 22, 2002 office meeting
concerning the cumulative impacts to the watershed (comment 1 on the July 30th letter) of
the proposed Salem Castle project.
The channel present on site is buffered throughout its existence on-site. As the channel
exits the project site it enters the State Capital Soccer Park (SCSP) Project and then flows
into Walnut Creek. The stream channel has a 100-foot buffer on each side throughout its
extent on the SCSP site. The channel joins another tributary (feature B) on the SCSP site
prior to entering Walnut Creek. Feature B has a 50-foot buffer applied to each side. The
area in the vicinity of the stream channel on the SCSP site that has not already been
developed does not have any plans for development.
The SCSP site has a cross country trail planned which will cross the creek. The permit
application for this trail is currently being prepared and will be submitted shortly. The
trail proposes a vegetated trail (grass) and will avoid all large diameter trees. The
proposed trail plan has changed slightly and will proposed the use of a culvert and/or fill
to cross the creek with an impact of approximately 15 linear feet at each crossing.
After discussions with Integrated Design, the Salem Castle site planner, the site should
not contribute to any cumulative impacts downstream because stormwater from the site is
being treated prior to entering the buffers and/or stream and is required to meet the Town
of Cary's strict stormwater BMP's.
As requested I have attached a copy of the current zoning for the surrounding properties
in the same small watershed. The watershed size, which includes the area draining
Feature B. is approxw 73 acres- As shown nn the attached ?nnin??yp? the

proposed site is zoned "business," the area immediately west of the site with frontage on
East Chatham Street is zoned "business," the area west of the site and between the SCSP
and the area zoned business is zoned "residential." The mobile home park west of the
SCSP currently exists. The SCSP also currently exists. The area north of the site and
north of East Chatham Street is zone "industrial" however; East Chatham Street is on a
ridge that divides two drainages so areas north of East Chatham Street are in another
drainage basin.
Please call me at the number listed below or email me at SClarkASandEC.com if you
have any further questions.

DWQ # 02-1162
Wake County
On July 23, 2002 the Division of Water Quality (DWQ) was notified by receipt of your application
regarding your plan to fill wetland for the purpose of constructing a commercial development (Salem Castle
Site) in Cary. Approval from DWQ is required to disturb these wetlands. Please provide seven copies of the
following information and refer to the DWQ# listed above in your reply. In particular as described in 15A
NCAC 2B .0502, we will require you to locate all streams and ponds on the property. Please show these on
maps of suitable scale (for instance 1" = 100 feet) so we can begin to determine your projects' compliance with
15A NCAC 2H.0500.
1. Please address whether any cumulative impacts on downstream water quality will likely occur as a
result of this development. Please contact me to get a copy of DWQ latest cumulative impact policy,
which should give you some guidance on how to address this issue.
2. The Stormwater Best Management Practice's designed according to condition 3 of GC 3362 were
not provided for the entire site. They must be provided for the entire site including all of the parking
areas, which was not shown on the site plan you provided.
3. The plans you provided showed structural impacts (retaining wall?) in Zone 2. This would require a
variance to the Neuse Buffer Rules. If you proposed to pursue this variance please forward a
Variance Request form. You should contact Bob Zarzecki at 919-733-9726 to discuss this issue
prior to providing your response.
4. Please provide plans with a -scale of 50:1 or less so that the impacts to the wetlands can be
adequately evaluated.
Please telephone me at 919-733-1786 if you have any questions or would require copies of our rules
or procedural materials. This project will remain on hold as incomplete in accordance with 15A NCAC 2H
.0505(c). The processing time for this application will begin when this information is received. If we do not
hear from you by writing within three (3) weeks we will assume you no longer want to pursue the project and
will consider it withdrawn.

Salem Castle was or should have been put on hold a month ago for lack of stormwater at the main
crossing. Debbie has the minor variance one and it is a piece of crap. Looks like the guy just moved the
stream out of the way on the diagram and it is not located where it really is in the field.

Hi Steve and Debbie.
Below is this week's 401 Tracking Notice for the Raleigh Regional Office. The Central Office has not
received your recommendations for these projects as of October 30, 2002. If you have not received any
application, please let me know and I will fax it to you. Please take note of the date received in the
Central Office and the 60-day clock projection. If we do not have your comments by two weeks before
the clock expires, we may have to prepare the 401 without incorporating your comments, in order to
avoid waiving the 401. Two weeks from today, the application will be forwarded to the appropriate
Central Office staff member (Cyndi Karoly ) if we do not have Regional Office comments by then. The
CO staff will then consult you if time allows and make a recommendation on the 401 to John Dorney.

Re: Reply to the Division of Water Quality's July 30, 2002 letter req es arCh'er
information for the proposed Salem Castle Site, Cary, Wake County, North Carolina
Dear Mr. Dorney:
This letter is in response to your letter dated May 30, 2002 (copy attached), which
requested additional information. The stream contained on property has been located its
location is depicted on the site plan previously submitted to you. A copy of this site plan
is attached. The following points are meant to correspond directly to your letter.
1) The wetland with proposed impacts is above a stream feature that continues
approximately 2000 feet prior to draining into Walnut Creek (Neuse River
Basin). The channel exits the property and then runs through the State Capital
Soccer Park (SCSP) Project at which point it intersects with Walnut Creek.
The stream channel is buffered through out its extent on the Salem Castle Site
and the SCSP Site. The area in the vicinity of the stream channel on the SCSP
site that has not already been developed does not have any plans for
development. The
SCSP site has a cross country trail planned which will cross the creek. The
permit application for this trail is currently being prepared and will be
submitted shortly. The trail proposes a vegetated trail (grass) and will avoid
all large diameter trees. The proposed trail will not use a culvert and/or fill to
cross the creek.
After discussions with Integrated Design, the Salem Castle site planner, the
site should not contribute to any cumulative impacts downstream because
stormwater from the site is being treated prior to entering the buffers and/or
stream.
2) Six Bioretention cells are proposed to treat the stormwater from the parking
lot. The attached "Map 2" has these areas labeled. If any further details or

calculations are required please contact Mr. Terry Gleason of Integrated
Design @ 832-6658.
3) There are no retaining walls or permanent structures proposed within Zone 2
for the site. A temporary silt fence and tree protection fencing are shown on
the site plan in some small portions of Zone 2, which should not require a
variance.
4) As requested, the attached maps are at a scale of 1:50.
The applicant does not wish to withdraw the application. If I can be of any further
assistance or if you have any questions, please let me know.

Re: §401 Water Quality Certification Application for Wake County;

DWQ # 02-1162
Dear Mr. Clark:
Alan W. Klimek, P.E. Director
Division of Water Quality
?r
NOV - 6 2,02
The Division of Water Quality has reviewed your modified submittal (dated September
10, 2002) for a §401 Water Quality Certification for the aforementioned project. We have
several questions about this project as outlined below:
1. It appears that a retaining wall is still planned within Zone 2 of the stream buffer at
the southwestern part of the site (adjacent to the loading dock?). Please address
this issue.
2. Stormwater plan - This project shall require a stormwater management plan for
the entire site that includes bioretention areas, extended detention wetlands
and/or wet or dry ponds followed by forested filter strips designed to meet 85%
TSS removal criteria according the NC DENR Stormwater Best Management
Practices Manual, April 1999 as required by General Certification 3362 and/or
3375. These requirements may be in addition to the nutrient reduction
requirements administered by the Town of Cary. Additionally, please provide
details as to whether a direct discharge of stormwater is planned at the road
crossing or whether this stormwater will be treated before discharge. Also the
stormwater discharge from the castle itself will need to be treated before
discharge to the stream. The plan does not show any treatment devices in this
location. We will need preliminary designs or calculations for the bioretention
areas before we can issue the required approval so we can be certain that this
treatment is feasible.
3. Please address the shape of the protected stream buffer at the northwest corner
of the castle. The shape of the buffer is not symmetric - that is, it bends
northward from the castle but is not similarly bent on the opposite side of the
stream. We are concerned that the stream and buffer locations may not be
properly shown. Please submit information which depicts the exact location of the
buffer and stream on the site.
Pursuant to 15A NCAC 21-1.0507(a)(3), the permit application will remain on hold until
we are supplied the necessary information. Furthermore, until the information is received by the
NC Division of Water Quality, we request (by copy of this letter) that the US Army Corps of
Engineers continue to place the permit application on hold. I would suggest that you call me to
schedule a meeting in our office with myself, Todd St. John, Steve Mitchell, yourself and
Terry Gleason (engineer?) to discuss these issues in order to expedite our review.

Re: §401 Water Quality Certification Application for Wake County;
Salem Castle site
Wake County
DWQ # 02-1162
Dear Mr. Clark:
The Division of Water Quality has reviewed your modified submittal (dated September
10, 2002) for a §401 Water Quality Certification for the aforementioned project. We have
several questions about this project as outlined below:
1. It appears that a retaining wall is still planned within Zone 2 of the stream buffer at
the southwestern part of the site (adjacent to the loading dock?). Please address
this issue.
2. Stormwater plan - This project shall require a'stormwater management plan for
the entire site that includes bioretention areas, extended detention wetlands
and/or wet or dry ponds followed by forested filter strips designed to meet 85%
TSS removal criteria according the NC DENR Stormwater Best Management
Practices Manual, April 1999 as required by General Certification 3362 and/or
3375. These requirements may be in addition to the nutrient reduction
requirements administered by the Town of Cary. Additionally, please provide
details as to whether a direct discharge of stormwater is planned at the road
crossing or whether this stormwater will be treated before discharge. Also the
stormwater discharge from the castle itself will need to be treated before
discharge to the stream. The plan does not show any treatment devices in this
location. We will need preliminary designs or calculations for the bioretention
areas before we can issue the required approval so we can be certain that this
treatment is feasible.
3. Please address the shape of the protected stream buffer at the northwest corner
of the castle. The shape of the buffer is not symmetric - that is, it bends
northward from the castle but is not similarly bent on the opposite side of the
stream. We are concerned that the stream and buffer locations may not be
properly shown. Please submit information which depicts the exact location of the
buffer and stream on the site.
Pursuant to 15A NCAC 2H .0507(a)(3), the permit application will remain on hold until
we are supplied the necessary information. Furthermore, until the information is received by the
NC Division of Water Quality, we request (by copy of this letter) that the US Army Corps of
Engineers continue to place the permit application on hold. I would suggest that you call me to
schedule a meeting in our office with myself, Todd St. John, Steve Mitchell, yourself and
Terry Gleason (engineer?) to discuss these issues in order to expedite our review.

application. If you have any questions or require additional information, please contact me at

will be approved by the U.S. Army Corps of Engineers and the N.C. Division of Water Quality Wetlands/401
Unit. It is the responsibility of the applicant to contact these agencies to determine if payment to the NCWRP
for impacts associated with this project is appropriate.
This acceptance is valid for six months from the date of this letter. If we have not received a copy of the issued
404 Permit/401 Certification within this time frame, this acceptance will expire.
Based on the information supplied by you in a letter dated September 5, 2002, the wetland restoration that is
necessary to satisfy the compensatory mitigation requirements for this project is summarized in the following
table. The maximum amount of mitigation that the NCWRP will accept for this project is also indicated in this
