APPROVAL of 401 Water Quality Certification with Additional Conditions
Dear Mr. Reitzel:
Seaboard Chemical Corporation has our approval, in accordance with the attached conditions, to place
permanent fill in 58 linear feet of perennial stream for the purpose of constructing an access road to the
Riverdale Road Landfill in High Point, Guilford County, as described in your application received by the
Division of Water Quality on August 16, 2005. After reviewing your application, we have determined that this
fill is covered by General Water Quality Certification Number 3404, which can be viewed on our web site at
http://h2o.enr.state.nc.us/ncwetlands. This Certification allows you to use Nationwide Permit Number 14 when
it is issued by the U.S. Army Corps of Engineers. In addition, you should secure any other applicable federal,
state or local permits before you proceed with your project, including (but not limited to) those required by
Sediment and Erosion Control, Non-Discharge, and Water Supply Watershed regulations. Also, this approval
will expire when the accompanying 404 permit expires unless otherwise specified in the General Certification.
This approval is valid only for the purpose and design that you have described in your application. If you
change your project, you must notify us in writing and you may be required to send us a new application for a
new certification. If the property is sold, the new owner must be given a copy of the 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 2H .0506
(h). For this approval to be valid, you must follow the conditions listed in the attached certification, as
well as the additional conditions listed below:
The following impacts are hereby approved as long as all other specific and general conditions of this
Certification are met. No other impacts, including incidental impacts, are approved:

2. The culvert required for this project shall be installed in such a manner that the original stream profile is
not altered (i.e. the depth of the channel must not be reduced by a widening of the streambed). Existing
stream dimensions (including the pattern and profile) are to be maintained above and below the location
of the culvert. The culvert shall be designed and installed to prevent head cutting of the stream. If the
culvert becomes perched, the appropriate stream grade shall be re-established or, if the culvert is
installed in a perched manner, the culvert shall be removed and re-installed correctly. The Applicant
must submit a plan and receive written approval from this Office to address any head cutting that will
occur as a result of this project (e.g., use of cross vanes downstream of the culvert).
Where riprip is required for energy dissipation and scour protection, it shall be limited to the minimum
dimensions specified by appropriate engineering calculations. Riprap may only be used below the
normal high water level. The original grade and elevation of the stream's cross-section must be
maintained. Riprap placed in the streambed must be inserted into the bed matrix to a depth sufficient to
provide the thickness of riprap required for scour protection. The elevation of the streambed must not be
increased by the placement of riprap. Placement of riprap must not result in destabilization of the
streambed or banks upstream or downstream of any crossing.
4. This project shall provide energy dissipation and sheet flow for any stormwater discharges generated by
the stream crossing prior to their entering the stream channel.
5. Upon completing the project, the Applicant shall fill out and return the enclosed "Certificate of
Completion" to notify NCDWQ when all work included in the §401 Certification has been finished.
This certificate should be returned to the 401/Wetlands Unit of the NC Division of Water Quality at the
address listed on the form. Along with the Certificate of Completion, please send photographs upstream
and downstream of the culvert site to document correct installation.
If you do not accept any of the conditions of this certification, you may ask for an adjudicatory hearing. You
must act within 60 days of the date that you receive this letter. To ask for a hearing, send a written petition
which conforms to Chapter 150B of the North Carolina General Statutes to the Office of Administrative
Hearings, 6714 Mail Service Center, Raleigh, N.C. 27699-6714. This certification and its conditions are final
and binding unless you ask for a hearing.
This letter completes the review of the Division of Water Quality under Section 401 of the Clean Water Act. If
you have any questions, please telephone Daryl Lamb in the DWQ Winston-Salem Regional Office at 336-771-
4600 or Cyndi Karoly in the Central Office in Raleigh 919-733-9721.

The purpose of this letter is to request the use of Nationwide Permit 14 for propos?E?iOW'61 QUALITY RMWATER waters of the US at the former Seaboard Chemical facility/Riverdale Road Landfill in High Point,jCH
NC. The project area is located west of Interstate 85 north of Riverdale Road. Both the Seaboard
site and landfill are inactive. The approximate boundaries of the Seaboard site and landfill are
shown on the attached USGS Topo Quad vicinity map and USDA Guilford County Soil Survey,
and a vicinity map. Surface waters on the property flow to Deep River. The Deep River is the
eastern property boundary of the landfill. The property is in the Randleman Lake watershed and
the Deep River is classified WSIV,CA.
S&EC has delineated a jurisdictional stream on the former Seaboard Chemical site. The former
Seaboard Chemical Corporation and City of High Point are undertaking remediation efforts to
capture, store and treat contaminated groundwater and leachates from the Seaboard site and
landfill before entering the Deep River. The overall project purpose related to this
preconstruction notification is outlined more clearly in a proposed scope of work included with
this submittal. Mr. Rick Sanderson of Environmental Resources Management (ERM) in
Charlotte has prepared a description and proposed timeline of the work included in this submittal.
In order to facilitate remediation efforts on the project our clients propose a road crossing of a
perennial stream. S&EC met on site with personnel from the USACE and NC DWQ to classify
the stream/approve our delineation. The stream in question occurs on the Seaboard Chemical
property. The proposed road will provide access as well as a utility crossing across the 160-acre
landfill. Proposed impacts will involve 58 If of stream for placement of a 48" pipe and rip rap.
The proposed impact has been reduced from previous plans and is strategically placed to provide
easy access to groundwater wells.
Attached please find: 1) A completed Preconstruction Notification 2) proposed Scope of Work 3)

improved access across 160 acre landfill Overall proiect purpose is to mitigate impaired ground
water by mechanical and natural processes before entering Randleman Reservoir.
VIII. Mitigation
DWQ - In accordance with 15A NCAC 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 January 15, 2002, 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 NCEEP 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
ide.html.

choose to list constraints associated with construction or sequencing that may impose limits on
work schedules (e.g., draw-down schedules for lakes, dates associated with Endangered and
Threatened Species, accessibility problems, or other issues outside of the applicant's control).

Forster Seaboard Chemical Facility/Riverdale Drive Lan(UH1 Site
The proposed remediation system at the Former Seaboard Chemical Facility and City of High
Point Riverdale Drive Landfill Site is being installed to collect impacted groundwater and
leachate from the landfill to minimize the impacts to the future Randleman Reservoir.
Groundwater recovery wells and leachate recovery tanks have been installed throughout the Site
at locations to collect the greatest quantity of impacted groundwater and leachate. Piping to
collect the impacted groundwater and leachate will be installed from the existing groundwater
recovery wells and leachate tanks to a series of lift stations and ultimately to the Treatment
Building and Riverdale Wastewater Pumping Station. The majority of the pipes will be installed
along the shoulders of existing site roads or in previously disturbed areas to minimize impacts to
vegetation on the Site. The pipes installed from the Treatment Building to the Riverdale
Wastewater Pumping Station will be installed along the top of the former landfill area.
Groundwater will be pumped from the aquifer utilizing groundwater recovery wells installed
throughout the site. The groundwater will be pumped from the aquifer and piped to the
Treatment System Building location adjacent to the existing Maintenance Building. Leachate
will be removed from the site utilizing existing leachate collection lines, which tie into leachate
collection tanks. The leachate will be pumped from the leachate collection tanks and piped to the
Treatment System Building location adjacent to the existing Maintenance Building.
The groundwater and leachate will be mixed together in the Treatment System Building prior to
treatment. The treatment processes being utilized at this site include a combination of mechanical
and natural methods. The mechanical methods being implemented include injection of a
sequestering agent, a sand filter, an air stripper, and a HiPOx unit. The HiPOx unit is a patented
treatment system that utilizes ozone and hydrogen peroxide to treat contaminants. The natural
processes being implemented include a constructed wetland and phytoremediation.
Due to the concentrations of metals (i.e. mainly iron and manganese) naturally present in the
groundwater, a sequestering agent will be injected at different locations throughout the piping
runs to keep the iron and manganese in solution rather than allowing them to settle out and foul
the pipes, lift stations, and treatment processes.
Once the groundwater and leachate reach the Treatment System Building they will be mixed
together. Initially, the mixture will be pumped through a sand filter to remove any suspended
solids from the mixture, then the mixture will be pumped through an air stripper to remove
volatile organic compounds (VOCs) from the mixture and then through a HiPOx unit to remove
1,4-Dioxane from the mixture prior to discharging the treated mixture to the City of High Point
East Side Wastewater Treatment Plant. Following the construction and maturation of the
constructed wetlands, the groundwater and leachate may be pumped to the constructed wetlands
to remove the VOCs after they have been mixed together, then pumped to the sand filter to
remove any suspended solids from the mixture and then to the HiPOx unit to remove 1,4-Dioxane
from the mixture prior to discharging the treated mixture to the City of High Point East Side
Wastewater Treatment Plant. Following the planting and maturation of the trees in the
phytoremediation area, the groundwater and leachate will be pumped to the constructed wetlands
to remove the VOCs after they have been mixed together and then to the phytoremediation area to
remove 1,4-Dioxane from the mixture. Once the constructed wetlands and phytoremediation area
are fully operational, the use of the air stripper and HiPOx unit will be minimized and they will
be used only when additional treatment of the mixture is required to meet regulatory requirements
or when quantities of the treated mixture exceed what the constructed wetland or
phytoremediation system can effectively treat.
The breakdown of the Phase II Remediation System is as follows:
Groundwater Recoverv and Treatment
• Groundwater will be recovered (pumped) from recovery wells located ill four areas
throughout the Site designated as:
¦ Loop Road Area (RW-LFS 1, RW-LFS2)
¦ SIS Area (PW-DR1, RW-SIS1)
¦ NIS Area (RW-NIS1)
¦ Seaboard Area (RW-SIS2, RW-SIS3, RW-SIS4)
• Groundwater from Loop Road Area is pumped to Lift Station Number 8.
• Groundwater from Lift Station Number 8 is pumped to Lift Station Number 2 in tile SIS
Area.
• Groundwater from the SIS Area is pumped to Lift Station Number 2.
• Groundwater from Lift Station Number 2 is pumped to Lift Station Number 1 in tile NIS
Area.
• Groundwater from the NIS Area is pumped to Lift Station Number 1.
• Groundwater from Lift Station Number 1 is pumped to the Treatment Building.
• Groundwater from the Seaboard Area is pumped to Lift Station Number 3 in the Seaboard
Area.
• Groundwater from Lift Station Number 3 is pumped to the Treatment Building.
Leachate Recoverv and Treatment
• Leachate will be recovered (pumped) from collection tanks located in three areas throughout
the Site designated as:
¦ Loop Road Area (LCHT-1, LCHT-2)
¦ SIS Area (LCHT-3, LCHT-4, LCHT-5)
¦ NIS Area (NIS-LCHT)
• Leachate from Loop Road Area is pumped to Lift Station Number 8.
• Leachate from Lift Station Number 8 is pumped to Lift Station Number 2 in the SIS Area.
• Leachate from the SIS Area is pumped to Lift Station Number 2.
• Leachate from Lift Station Number 2 is pumped to Lift Station Number 1 in the NIS Area.
• Leachate from the NIS Area is pumped to Lift Station Number 1.
• Leachate from Lift Station Number 1 is pumped to the Treatment Building.
• Groundwater and Leachate at the Treatment Building (from Lift Stations Number 1 & 3) is
combined in Surge Tank #I at the Treatment Building.
Phase I - All Mechanical Svstem before Constructed Wetland or Phvtoremediation Area Installed
• The groundwater/leachate mixture from Surge Tank #1 is pumped into the Air Stripper at the
Treatment Building for treatment of VOCs.
• The Treated Water from the Air Stripper is pumped into the HiPOx Treatment System for
treatment of 1,4-Dioxane and then into Lift Station Number 6.
• The Treated Water from Lift Station Number 6 is pumped to Lift Station Number 7 at the
Phytoremediation Area.
• Part of the treated water from Lift Station Number 7 is used to irrigate the Phytoremediation
Pilot Plot Area and the remainder of the treated water is pumped to the Riverdale Wastewater
Pumping Station for disposal at the City of High Point East Side Waste Water Treatment
Plant.
Phase 11- After the Constriction of the Constructed Wetlands is Complete
• Part of the groundwater/leachate mixture from Surge Tank #1 is pumped via Lift Station
Number 4 to the Constructed Wetlands and the remainder of tile groundwater/leach ate
mixture from Surge Tank #1 is pumped into the Air Stripper at the Treatment Building for
treatment of VOCs.
• The groundwater/leachate mixture pumped to the Constructed Wetlands travels through the
Constructed Wetlands and the treated water discharges into Lift Station Number 5.
• The Treated Water from Lift Station Number 5 is pumped to the Surge Tank 42 at the
Treatment Building.
• The Treated Water from the Air Stripper is pumped into Surge Tank #2 at the Treatment
Building.
• The Treated Water from Surge Tank 92 goes through the HiPOx Treatment System and
discharges into Lift Station Number 6.
• The Treated Water from Lift Station Number 6 is pumped to Lift Station Number 7 at the
Phytoremediation Area.
• Part of the treated water from Lift Station Number 7 is used to irrigate tile Phytoremediatioll
Pilot Plot Area and the remainder of the treated water is pumped to the Riverdale Wastewater
Pumping Station for disposal at the City of High Point East Side Waste Water Treatment
Plant.
Phase III - Constructed Wetlands is mature and the Full Phvtoremediation Svstem is installed
• The groundwater/leachate mixture from Surge Tank #1 is pumped via Lift Station Number 4
to the Constructed Wetlands.
• The groundwater/leachate mixture travels through the Constructed Wetlands and the treated
water discharges into Lift Station Number 5.
• The Treated Water from Lift Station Number 5 is pumped to Surge Tank 92 at the Treatment
Building.
• The Treated Water from Surge Tank 42 bypasses the HiPOx Treatment System and
discharges into Lift Station Number 6.
• The Treated Water from Lift Station Number 6 is pumped to Lift Station Number 7 at the
Phytoremediation Area.
• The treated water from Lift Station Number 7 is used to irrigate the Phytoremediation Area.

Dear Mr. Tugwell and Ms. Karoly:
DENR - WATER QUALITY
The purpose of this letter is to request the use of Nationwide Permit 14 for proposed ?i pa4e ffiSTORIA'ATER BUTCH
waters of the US at the former Seaboard Chemical facility/Riverdale Road Landfill in High Point,
NC. The project area is located west of Interstate 85 north of Riverdale Road. Both the Seaboard
site and landfill are inactive. The approximate boundaries of the Seaboard site and landfill are
shown on the attached USGS Topo Quad vicinity map and USDA Guilford County Soil Survey,
and a vicinity map. Surface waters on the property flow to Deep River. The Deep River is the
eastern property boundary of the landfill. The property is in the Randleman Lake watershed and
the Deep River is classified WSIV,CA.
S&EC has delineated a jurisdictional stream on the former Seaboard Chemical site. The former
Seaboard Chemical Corporation and City of High Point are undertaking remediation efforts to
capture, store and treat contaminated groundwater and leachates from the Seaboard site and
landfill before entering the Deep River. The overall project purpose related to this
preconstruction notification is outlined more clearly in a proposed scope of work included with
this submittal. Mr. Rick Sanderson of Environmental Resources Management (ERM) in
Charlotte has prepared a description and proposed timeline of the work included in this submittal.
In order to facilitate remediation efforts on the project our clients propose a road crossing of a
perennial stream. S&EC met on site with personnel from the USACE and NC DWQ to classify
the stream/approve our delineation. The stream in question occurs on the Seaboard Chemical
property. The proposed road will provide access as well as a utility crossing across the 160-acre
landfill. Proposed impacts will involve 58 if of stream for placement of a 48" pipe and rip rap.
The proposed impact has been reduced from previous plans and is strategically placed to provide
easy access to groundwater wells.
Attached please find: 1) A completed Preconstruction Notification 2) proposed Scope of Work 3)
signed Agent Authorization Form, 4) USGS topo quad vicinity map, 5) Guilford County Soil
Survey map, 6) Vicinity map, 7) Construction plans, 8) Upland data form, 9) previous
Nationwide 38, 404/401 approvals, and 10) a $200 check for 401 fees.

III. Project Information
Attach a vicinity map clearly showing the location of the property with respect to local
landmarks such as towns, rivers, and roads. Also provide a detailed site plan showing property
boundaries and development plans in relation to surrounding properties. Both the vicinity map
and site plan must include a scale and north arrow. The specific footprints of all buildings,
impervious surfaces, or other facilities must be included. If possible, the maps and plans should
include the appropriate USGS Topographic Quad Map and NRCS Soil Survey with the property
boundaries outlined. Plan drawings, or other maps may be included at the applicant's discretion,
so long as the property is clearly defined. For administrative and distribution purposes, the
USACE requires information to be submitted on sheets no larger than 11 by 17-inch format;
however, DWQ may accept paperwork of any size. DWQ prefers full-size construction
drawings rather than a sequential sheet version of the full-size plans. If full-size plans are
reduced to a small scale such that the final version is illegible, the applicant will be informed that
the project has been placed on hold until decipherable maps are provided.

10. Describe the overall project in detail, including the type of equipment to be used:
Groundwater and leachate from the former Seaboard Chemical facility and City landfill will
be captured stored treated and eventually sent to the wastewater treatment plant across
Riverdale Drive Recove_1y wells and tanks exist throughout the site. Piping from the wells to
a mechanical treatment Ustem building onsite must be installed. Heave equipment including
Bulldozers and backhoes will be used to construct the proposed road crossing and trenches
for pipes from wells to the treatment facility.
11. Explain the purpose of the proposed work: Purpose of requested impact to construct a road
which will involve a stream crossing for vehicle access across the 160 acre landfill. Larger
purpose of project is groundwater remediation for the former Seaboard Chemical facility nad
Riverdale Drive landfill Groundwater and leachate will be captured treated on site and sent
to the wastwater pumping station across from the landfill. Overall project purpose is to clean
groundwater from the site before entering the proposed Randleman Reservoir. An attachment
from ERM better outlines the purpose and schedule of the proposed work. Once complete a
constructed wetland and phytoremediation will provide natural treatment of the groundwater.

water by mechanical and natural processes before entering Randleman Reservoir.
VIII. Mitigation
DWQ - In accordance with 15A NCAC 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 January 15, 2002, 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 NCEEP concurrence shall be placed on hold as incomplete.
An applicant may also choose to review the current guidelines for stream restoration in DWQ's

Former Seaboard Chemical Facility/Riverdale Drive Landfill Site
The proposed remediation system at the Former Seaboard Chemical Facility and City of High
Point Riverdale Drive Landfill Site is being installed to collect impacted groundwater and
leachate from the landfill to minimize the impacts to the future Randleman Reservoir.
Groundwater recovery wells and leachate recovery tanks have been installed throughout the Site
at locations to collect the greatest quantity of impacted groundwater and leachate. Piping to
collect the impacted groundwater and leachate will be installed from the existing groundwater
recovery wells and leachate tanks to a series of lift stations and ultimately to the Treatment
Building and Riverdale Wastewater Pumping Station. The majority of the pipes will be installed
along the shoulders of existing site roads or in previously disturbed areas to minimize impacts to
vegetation on the Site. The pipes installed from the Treatment Building to the Riverdale
Wastewater Pumping Station will be installed along the top of the former landfill area.
Groundwater will be pumped from the aquifer utilizing groundwater recovery wells installed
throughout the site. The groundwater will be pumped from the aquifer and piped to the
Treatment System Building location adjacent to the existing Maintenance Building. Leachate
will be removed from the site utilizing existing leachate collection lines, which tie into leachate
collection tanks. The leachate will be pumped from the leachate collection tanks and piped to the
Treatment System Building location adjacent to the existing Maintenance Building.
The groundwater and leachate will be mixed together in the Treatment System Building prior to
treatment. The treatment processes being utilized at this site include a combination of mechanical
and natural methods. The mechanical methods being implemented include injection of a
sequestering agent, a sand filter, all air stripper, and a HiPOx unit. The HiPOx unit is a patented
treatment system that utilizes ozone and hydrogen peroxide to treat contaminants. The natural
processes being implemented include a constructed wetland and phytoremediation.
Due to the concentrations of metals (i.e. mainly iron and manganese) naturally present in the
groundwater, a sequestering agent will be injected at different locations throughout the piping
runs to keep the iron and manganese in solution rather than allowing them to settle out and foul
the pipes, lift stations, and treatment processes.
Once the groundwater and leachate reach the Treatment System Building they will be mixed
together. Initially, the mixture will be pumped through a sand filter to remove any suspended
solids from the mixture, then the mixture will be pumped through an air stripper to remove
volatile organic compounds (VOCs) from the mixture and then through a HiPOx unit to remove
1,4-Dioxane from the mixture prior to discharging the treated mixture to the City of High Point
East Side Wastewater Treatment Plant. Following the construction and maturation of the
constructed wetlands, the groundwater and leachate may be pumped to the constructed wetlands
to remove the VOCs after they have been mixed together, then pumped to the sand filter to
remove any suspended solids from the mixture and then to the HiPOx unit to remove 1,4-Dioxane
from the mixture prior to discharging the treated mixture to the City of High Point East Side
Wastewater Treatment Plant. Following the planting and maturation of the trees in the
phytoremediation area, the groundwater and leachate will be pumped to the constructed wetlands
to remove the VOCs after they have been mixed together and then to the phytoremediation area to
remove 1,4-Dioxane from the mixture. Once the constructed wetlands and phytoremediation area
are fully operational, the use of the air stripper and HiPOx unit will be minimized and they will
be used only when additional treatment of the mixture is required to meet regulatory requirements
or when quantities of the treated mixture exceed what the constructed wetland or
phytoremediation system can effectively treat.
The breakdown of the Phase II Remediation System is as follows:

APPROVAL of 401 Water Quality Certification and AUTHORIZATION CERTIFICATE
City of High Point
211 South Hamilton Street, Post Office Box 230
High Point, NC 27261
Subject Property: Riverdale Road Landfill
You have our approval, in accordance with the attached conditions, to impact 0.02 acres of waters for a detention
pond, 25 feet perennial stream and 0.05 acres of buffers for the purpose of exploratory excavation as you
described in your application dated December 5, 2003. After reviewing your application, we have decided that
this fill is covered by General Water Quality Certification Number 3360, which may be viewed on our website at
http//h2o.enr.state.nc.us/ncwetlands. This certification allows you to use Nationwide Permit Number 38 when
the Corps of Engineers issues it. 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 2H.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.
Conditions of Certification:
1. Upon completion of all work approved within the 401 Water Quality Certification or applicable Buffer
Rules, and any subsequent modifications, the applicant is required to return the attached certificate of
completion to the 401/Wetlands Unit, North Carolina Division of Water Quality, 1650 Mail Service
Center, Raleigh, NC, 27699-1650.
2. Erosion & Sediment Control Practices
Erosion and sediment control practices must be in full compliance with all specifications governing the
proper design, installation and operation and maintenance of such Best Management Practices in order
to protect surface waters standards:
a. The erosion and sediment control measures for the project must be designed, installed, operated,
and maintained in accordance with the most recent version of the North Carolina Sediment and
Erosion Control Planning and Design Manual.
