APPROVAL of 401 Water Quality Certification with Additional Conditions
Dear Mr. Connell:
You have our approval to conduct stream restoration activities along a total of 950 linear feet of an unnamed
tributary to Beaver Creek located on your property at 6380 Gumwood Road in Oak Ridge, Guilford County.
In addition, you have our approval to place permanent fill in 20 linear feet of this same unnamed tributary for
the purpose of installing a stream crossing. These activities are to be conducted in accordance with the
attached conditions and as described in your application received by the Division of Water Quality on July 27,
2005. After reviewing your application, we have determined that these activities are covered by General
Water Quality Certification Numbers 3404 and 3495, which can be viewed on our web site at
http://h2o.enr.state.nc.us/ncwetlands. These Certifications allow you to use Nationwide Permit Numbers 14
and 27 when they are 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 permits expire unless otherwise specified in the
General Certifications.
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 these Certifications 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
Certifications, as well as the additional conditions listed below:
1. The following impacts are hereby approved as long as all other specific and general conditions of the
Certifications are met. No other impacts, including incidental impacts, are approved:

2. Within 30 days of completion of construction, documentation must be provided which demonstrates that
the stream restoration plan has been implemented as proposed and approved. This documentation must
include as-built drawings showing that the restored stream reach has the profile, pattern, dimensions and
adjacent riparian zone specified by the restoration plan.
3. Appropriate sediment and erosion control measures which equal or exceed those outlined in the most
recent version of the North Carolina Sediment and Erosion Control Planning and Design Manual or the
North Carolina Surface Mining Manual (available from the Division of Land Resources at NCDENR
regional offices or the central office), whichever is more appropriate, shall be designed, installed and
maintained properly to assure compliance at all times with the North Carolina water quality standards
that are applicable to Class WS-III (NSW) waters as described in 15A NCAC 02B .0215 Fresh Surface
Water Quality Standards For Class WS-III Waters. Such measures must equal or exceed the
requirements specified in the most recent version of the North Carolina Sediment and Erosion Control
Manual. These measures must be maintained on all construction sites, borrow sites, and waste pile
(spoil) sites, including contractor owned and leased borrow pits, which are associated with this project.
4. Sediment and erosion control measures shall not be placed in wetlands or waters to the maximum extent
practicable. If placement of sediment and erosion control measures in wetlands or waters is
unavoidable, they shall be removed and the natural grade restored within six months of the date that the
project is completed or, if applicable, within six months of the date that the project is released by the
North Carolina Division of Land Resources.
5. No waste, spoil, solids, or fill of any kind shall occur in wetlands, waters, or riparian areas beyond the
footprint of the impacts depicted in the Pre-Construction Notification. All construction activities,
including the design, installation, operation, and maintenance of sediment and erosion control "Best
Management Practices" shall be performed so that no violations of state water quality standards,
statutes, or rules occur.
6. Monitoring of the restoration is required. Within 30 days of the date of this authorization, a monitoring
plan must be submitted to DWQ. This plan shall include the following items:
a) a 5-year monitoring schedule which is to be established upon completion of the restoration work.
For the first year of monitoring, quarterly inspections are required. After the first year, annual
inspections are required. The monitoring plan shall list a proposed schedule during which inspection
and review of the restoration will be conducted. No less than two bankfull flow events must be
documented during the 5-year monitoring period. If less than two bankfull events occur during the
first 5 years, monitoring will continue until the second bankfull event is documented. Monitoring
data collected shall include channel stability analysis, plant survival analysis, and reference photos.
b) clearly established monitoring stations (stream segments).
c) the requirement for written reports of all field inspections. These reports shall detail stream bank
stability, the condition of all measures constructed as a part of the restoration effort and whether any
measure is failing or showing evidence of pending failure, the condition of riparian restoration efforts
(including plantings) and whether any are failing or are not surviving, and measurements of the

amounts of sediment that are being deposited on the stream floor. These reports shall also assess the
effectiveness of diffuse stormwater flow and the condition and effectiveness of any stormwater
control measures that are required.
d) a written annual report due within 30 days of the end of each monitoring year. This annual report
shall be sent to DWQ's Winston-Salem Regional Office. The report must list the date of each
inspection, describe the inspection results, include digital photographs of each station, and describe
any repairs or corrections made and their dates of completion. For the first monitoring year, the
annual report shall also include copies of the quarterly field inspection reports.
e) procedures for undertaking repairs and corrections. If monitoring efforts show the need for repairs or
corrections to any restoration measure or riparian zone restoration effort, then such repairs or
corrections must be initiated within 20 days of the observation of such need. Any such repairs and/or
corrections shall be fully documented in the annual report.
Deviations from this protocol may be acceptable when they can be justified. Proposed exceptions will
be evaluated on a case-by-case basis by DWQ and will be coordinated with the U. S. Army Corps of
Engineers and other appropriate review agencies:
7. Upon finishing 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 completed.
This certificate should be returned to the 401/Wetlands Unit of the NC Division of Water Quality at the

were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts. The design for the
stabilization of the stream channel avoided several large diameter trees existing onsite in
order to preserve as much of the buffer as possible Efforts were made to disturb the
channel as little as possible, while still utilizing natural channel design principles and
providing a stable channel.
The proposed stream impacts due to the culverted crossing of an unnamed tributary Beaver
Creek are necessary in order to allow access to the remainder of the property. The invertof
the pipe will be buried so as to maintain a natural bed and allow for aquatic passage
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
hqp://h2o.enr.state.ne.us/ncwetlands/strmgide.html.

SUBJECT: NOTICE OF VIOLATION and RECOMMENDATION for ENFORCEMENT
ACTION
Failure to Secure a 401 Water Quality Certification
Stream Standard Violation
6380 Gumwood Road
Guilford County
Dear Mr. Connell:
On November 3, 2004, Mr. Daryl Lamb from the Winston-Salem Regional Office of the Department
of Environment and Natural Resources, Division of Water Quality, conducted a site inspection of the
subject property. Observations indicated that approximately 975 linear feet an unnamed tributary to
Beaver Creek, Cape Fear River Basin, Class WS-III, NSW waters, had been impacted by the
excavation of the stream banks, excavation of the streambed substrate (stream floor), removal of the
riffle-pools, and grading of the riparian area. During the site visit Mr. Lamb took measurements and
made observations of the stream impacts. As a result of these observations, the Winston-Salem
Regional Office conducted a file review. Accordingly, the following violations were confirmed as a
result of this review and the site inspection: 1) failure to obtain a Section 401 Water Quality
Certification, and 2) preclusion of best usage.
Violation 1. Failure to Obtain a Section 401 Water Quality. Certification
The Winston-Salem Regional Office confirmed that approximately 975 linear feet of stream channel
and banks had been impacted by excavation prior to the proper securing of a Section 404 Nationwide
Permit from the U. S. Army Corps of Engineers. A file review indicates that the U.S. Army Corps of
Engineers (COE) has not authorized use of a Nation Wide Permit for these activities nor has
notification been provided by the Corps of Engineers for these activities. Accordingly, the review
confirmed that no Pre-construction Notification has been received by the Division of Water Quality
for this project, and no Section 401 Water Quality Certification has been issued, nor are these
activities covered by a General Section 401 Water Quality Certification. A Section 401 Water

Quality Certification is required for the above-mentioned impacts pursuant to 15A NCAC 2H .0500.
Violation 2. Preclusion of Best Usase
A DWQ site visit and file review confirmed that approximately 975 linear feet of stream impacts
occurred to an unnarned tributary to Beaver Creek. Specifically, the impacts include the excavation of
the stream hank, excavation of the streambed substrate (stream floor), removal of the riffle-pools, and
the grading of the riparian area. These impacts to waters represent a removal of best usage, which is a
stream standard violation. Specifically, 15A NCAC 213.0211 (2) states that the preclusion of best
usage, which includes aquatic life propagation and maintenance of biological integrity, wildlife,
secondary recreation, and agriculture, represents a water quality standard violation.
Required Response and Corrective Action
The Division of Water Quality requires that the violations detailed above be abated immediately.
These violations, and any future violations, are subject to a civil penalty assessment of up to S25,000
per day for each violation. The Division of Water Quality requests that you respond in writing within
20 days of receiving this Notice. Please submit your written response to Daryl Lamb, Division of
Water Quality, Winston-Salem Regional Office, 585 Waughtown Street, Winston-Salem, NC 27107.
Your response should address the following items:
1. Please provide a map that details the location and number of feet of stream channel impact. This
map should clearly indicate the position of the impacted stream channel relative to adjacent
property lines, nearby buildings, roadways, culverts, ponds, sediment retention basins, and any
other significant structures immediately above and below the impacted reach.
2. Please explain why you did not secure authorization from the U. S. Arrny Corps of Engineers
(404 Permit) and the Division of Water Quality, N. C. Department of Environment and Natural
Resources, (401 Water Quality Certification) for this activity.
3. You must restore the impacted stream section and adjoining riparian area. You must submit a
stream restoration plan to the Division of Water Quality. Copies of this plan should be sent to
Danny Smith, Division of Water Quality, Wetlands and Stormwater Branch, Compliance and
Assistance Unit, 1617 Mail Service Center, Raleigh, NC 27699-1617 and to Daryl Lamb,
Division of Water Quality, Winston-Salem Regional Office, 585 Waughtown Street, Winston-
Salem, NC 27107. In addition, you should contact the U. S. Army Corps of Engineers at (919)
876-8441 and the Division of Land Resources, N. C. Department of Environment and Natural
Resources, Winston-Salem Regional Office, at [phone] to ensure that your restoration
plans are in compliance with the requirements of Section 404 of the Clean Water Act and the
requirements of the Division of Land Resources. This restoration plan must include your
proposal for the physical restoration of the stream to the original dimensions, pattern and profile
that existed before the dredging of the stream. This plan must also include the measures that will
be used to establish a stable stream channel, stream banks, and adjacent riparian zone. The plan
should include the following:
a) a reference stream with a description of its profile, pattern and dimensions and a detailed

description of the methods, materials, and structures necessary to install such a stream.
You arc encouraged to secure an environmental consultant to assist you with the plan's
development, and the securing of required permits, certifications and authorizations
necessary to implement the plan.
b) a riparian zone restoration plan. The stream banks and the riparian zone must be
stabilised and planted with woody vegetation. You should also specifically address tite
location of the riparian area to be restored and how you can insure that future impacts to
stream and the riparian zone will not occur. A planting plan must be developed and
implemented in order to ensure that at least two native tree species are planted at a
density sufficient to provide 320 trees per acre at maturity. This density is usually
achieved by planting approximately 436 trees/acre on a 10 x 10 ft. grid or 681 trees/acre
on an 8 x 8 ft. grid. Please see the attached Guiclelines.for Riparian Buffer Restoration
(January 2001) for assistance in developing your plan. This plan must include the types
of native woody vegetation selected, methodology of planting, and a site map indicating
the location of the replanting efforts.
4. In order to stabilize the strearnside areas in the interim, please immediately install temporary
ground cover along the stream banks. This ground cover should be suitable for the current soil
conditions and time of year.
We ask that you give your immediate attention to this matter and that your response address all of the
items listed above. Please be advised that this Office is considering sending a recommendation for
enforcement action to the Director of the Division of Water Quality regarding these issues. Your
response to this correspondence will be considered in this process. If you have questions concerning
this matter, or if this Office can be of assistance, please contact Daryl Lamb at [phone],
extension 293, or Danny Smith at [phone], extension 353.

Sediment shall be removed when it reaches 1/3 height of the fence or 9
inches maximum. Dispose of the sediment in the designated disposal
area.
11.6 PUMP AROUND OPERATIONS
The work covered by this item includes: providing, installing,
maintaining, and removing all equipment and materials associated with
the pumping of channel flow around work areas and dewatering zones
during construction. The Contractor shall utilize the specified and
appropriately sized pumps to convey the diversion of water flow away
from the work area without creating a flood hazard or scour. The
Contractor is responsible for determining (based on the direction of the
Engineer) the location of coffer dams, pumps, discharge hose route,
stilling basins, splash pads, and period of operation prior to the
initiation of any pumping. An attempt will be made to complete all
grading, channel shaping, in-stream structure construction, and
stabilization for each section within one day. If work for any particular
section cannot be completed in one day, a 24-hour pumping operation
will be set up and maintained to facilitate the construction schedule.
Bypass Pump
The pump used to convey the stream flow around the work area during
construction should be capable of pumping and discharging an
estimated 40 gallons per minute. The Contractor is responsible for
selecting a properly sized pump. This unit should be a silent and self-
priming model with a self-contained fuel tank large enough to facilitate
a 24-hour pumping operation. The pump should also be matched with
the necessary footage of flexible or ductile hose and appropriately sized
fittings.
Dewatering Pump
A second pump shall be used to dewater the work area between the
dams. The pump must be of sufficient size to dewater the work area
and pump that water from the bottom of the work area to the special
stilling basin. The pump should be matched with the necessary footage
of hose and the required fittings.
Special Stilling Basin
The special stilling basins are covered in detail under the "Special
Stilling Basins" section.
Temporary Splash Pad
A temporary splash pad shall be used to dissipate energy from the
discharge from the bypass pump. Alternatively, check dams may be
modified and used for this purpose as determined by the Engineer.
.11.7 SPECIAL STILLING BASINS
The work covered by this section consists of furnishing, placing, and
removing special stilling basins as directed by the plans and the
Engineer. The special stilling basins shall be used to filter pumped
water during construction. The quantity of special stilling basins may
be increased, decreased, or eliminated entirely at the direction of the
Engineer. Such variations in quantity will not be considered as
alterations in the details of construction or a change in the character of
work.

The special stilling basins shall be placed so the incoming water flows
through the bag without causing erosion. The bag will rest on
Nonwoven Type 2 filter fabric. The contractor will grade the bed to
ensure that the filtered water exits at the desired location. The exit
location shall be chosen to prevent erosion. The neck or spout of the
bag shall be tied tightly to prevent water from exiting the bag without
passing through the walls. The special stilling basin shall be disposed
of and replaced when it is 3/4 full of sediment, becomes torn or
punctured, or is unable to filter sediment at a reasonable flow rate.
Approval from Engineer must be received prior to removal and
replacement of special stilling basins. Contractor is responsible for
providing the necessary quantity of special stilling basins for the
duration of the project.

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
Page 5 of 9
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts. The design for the
stabilization of the stream channel avoided several large diameter trees existing onsite in
order to preserve as much of the buffer as possible Efforts were made to disturb the
channel as little as possible while still utilizing natural channel design principles and
providing a stable channel
The proposed stream impacts due to the culverted crossing of an unnamed tributary Beaver
Creek are necessary in order to allow access to the remainder of the property. The invertof
the pipe will be buried so as to maintain a natural bed and allow for aquatic passage
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.

ACTION
Failure to Secure a 401 Water Quality Certification
Stream Standard Violation
6 380 Gumwood Road
Guilford County
Dear Mr. Connell:
On November 3, 2004, Mr. Daryl Lamb from the Winston-Salem Regional Office of the Department
of Environment and Natural Resources, Division of Water Quality, conducted a site inspection of the
subject property. Observations indicated that approximately 975 linear feet an unnamed tributary to
Bcaver Creek, Cape Fear River Basin, Class WS-III, NSW waters, had been impacted by the
excavation of the stream banks, excavation of the streambed substrate (stream floor), removal of the
riffle-pools, and grading of the riparian area. During the site visit Mr. Lamb took measurements and
made observations of the stream impacts. As a result of these observations, the Winston-Salem
Regional Office conducted a file review. Accordingly, the following violations were confirmed as a
result of this review and the site inspection: 1) failure to obtain a Section 401 Water Quality
Certification, and 2) preclusion of best usage.
Violation 1. Failure to Obtain a Section 401 Water Quality Certification
The Winston-Salem Regional Office confirmed that approximately 975 linear feet of stream channel
and banks had been impacted by excavation prior to the proper securing of a Section 404 Nationwide
Permit from the U. S. Army Corps of Engineers. A file review indicates that the U.S. Army Corps of
Engineers (COE) has not authorized use of a Nation Wide Permit for these activities nor has
notification been provided by the Corps of Engineers for these activities. Accordingly, the review
confr3ed that no Pre-construction Notification has been received by the Division of Water Quality
for this project, and no Section 401 Water Quality Certification has been issued, nor are these
activities covered by a General Section 401 Water Quality Certification. A Section 401 Water

Quality Certification is required for the above-mentioned impacts pursuant to 15A NCAC 2H .0500.
Violation 2. Preclusion of Best Usage
A DWQ site visit and file review confirmed that approximately 975 linear feet of stream impacts
occurred to an unnamed tributary to Beaver Creek. Specifically, the impacts include the excavation of
the stream bank, excavation of the streambed substrate (stream floor), removal of the riffle-pools, and
the -rading of the riparian area. These impacts to waters represent a removal of best usage, which is a
stream standard violation. Specifically, 15A NCAC 213.0211 (2) states that the preclusion of best
usage, which includes aquatic life propagation and maintenance of biological integrity, wildlife,
secondary recreation, and agriculture, represents a water quality standard violation.
Required Response and Corrective Action
The Division of Water Quality requires that the violations detailed above be abated immediately.
These violations, and any future violations, are subject to a civil penalty assessment of up to S25,000
per day for each violation. The Division of Water Quality requests that you respond in writing within
20 days of receiving this Notice. Please submit your written response to Daryl Lamb, Division of
Water Quality, Winston-Salem Regional Office, 585 Waughtown Street, Winston-Salem, IBC 27107.
Your response should address the following items:
1. Please provide a map that details the location and number of feet of stream channel impact. This
map should clearly indicate the position of the impacted stream channel relative to adjacent
property lines, nearby buildings, roadways, culverts, ponds, sediment retention basins, and any
other significant structures immediately above and below the impacted reach.
2. Please explain.why you did not secure authorization from the U. S. Army Corps of Engineers
(404 Permit) and the Division of Water Quality, N. C. Department of Environment and Natural
Resources, (401 Water Quality Certification) for this activity.
3. You must restore the impacted stream section and adjoining riparian area. You must submit a
stream restoration plan to the Division of Water Quality. Copies of this plan should be sent to
Danny Smith, Division of Water Quality, Wetlands and Stormwrater Branch, Compliance and
Assistance Unit, 1617 Mail Service Center, Raleigh, NC 27699-1617 and to Daryl Lamb,
Division of Water Quality, Winston-Salem Regional Office, 585 Waughtown Street, Winston-
Salem, NC 27107. In addition, you should contact the U. S. Army Corps of Engineers at (919)
876-8441 and the Division of Land Resources, N. C. Department of Environment and Natural
Resources, Winston-Salem Regional Office, at [phone] to ensure that your restoration
plans are in compliance with the requirements of Section 404 of the Clean Water Act and the
requirements of the Division of Land Resources. This restoration plan must include your
proposal for the physical restoration of the stream to the original dimensions, pattern and profile
that existed before the dredging of the stream. This plan must also include the measures that will
be used to establish a stable stream channel, stream banks, and adjacent riparian zone. The plan
should include the following:
a) a reference stream with a description of its profile, pattern and dimensions and a detailed

description of the methods, materials, and structures necessary to install such a stream.
You arc encouraged to secure an environmental consultant to assist you with the plan's
development, and the securing of required permits, certifications and authorizations
necessary to implement the plan.
b) a riparian zone restoration plan. The stream banks and the riparian zone must be
stabilised and planted with woody vegetation. You should also specifically address the
location of the riparian area to be restored and how you can insure that future impacts to
stream and the riparian zone will not occur. A planting plan must be developed and
implemented in order to ensure that at least two native tree species are planted at a
density sufficient to provide 320 trees per acre at maturity. This density is usually
achieved by planting approximately 436 trees/acre on a 10 x 10 ft. grid or 681 trees/acre
on an 8 x 8 ft. grid. Please see the attached Guidelines for Riparian Buffer Restoration
(January 2001) for assistance in developing your plan. This plan must include the types
of native woody vegetation selected, methodology of planting, and a site map indicating
the location of the replanting efforts.
4. In order to stabilize the streamside areas in the interim, please immediately install temporary
ground cover along the stream banks. This ground cover should be suitable for the current soil
conditions and time ofycar.
We ask that you give your immediate attention to this matter and that your response address all of the
items listed above. Please be advised that this Office is considering sending a recommendation- for
enforcement action to the Director of the Division of Water Quality regarding these issues. Your
response to this correspondence will be considered in this process. If you have questions concerning
this matter, or if this Office can be of assistance, please contact Daryl Lamb at [phone],
extension 293, or Danny Smith at [phone], extension 353.

Connell Stream Restoration July 2005
The special stilling basins shall be a water permeable fabric bag that
traps sand, silt, and fines from the sediment laden water entering. The
filter fabric shall meet the requirements of Section 1056 for Type 2
Fabric.
The special stilling basin shall be a bag constructed to a minimum size
of 10' X 15' made from nonwoven fabric. There shall be a sewn-in 8
inch spout for receiving pump discharge. The bag seam shall be sewn
with a double needle machine using a high strength thread. The seams
shall have a minimum width strength of 60 lb/in (ASTM D-4884).
The fabric used to construct the bag shall be stabilized to provide
resistance to ultra-violet degradation and meet the following
specifications for flow rates, strength, and permeability:
Weight 8 oz/yd (ASTM D-3776)
Grab Tensile 200 lb (ASTM D-4632)
Puncture 130 lb (ASTM D-4833)
Flow Rate 80 gpm/sf (ASTM D-4491)
Permittivity 1.5 1/sec (ASTM D4991)
UV Resistance 70 % (ASTM D4355)
The special stilling basins shall be placed so the incoming water flows
through the bag without causing erosion. The bag will rest on
Nonwoven Type 2 filter fabric. The contractor will grade the bed to
ensure that the filtered water exits at the desired location. The exit
location shall be chosen to prevent erosion. The neck or spout of the
bag shall be tied tightly to prevent water from exiting the bag without
passing through the walls. The special stilling basin shall be disposed
of and replaced when it is '/. full of sediment, becomes tom or
punctured, or is unable to filter sediment at a reasonable flow rate.
Approval from Engineer must be received prior to removal and
replacement of special stilling basins. Contractor is responsible for
providing the necessary quantity of special stilling basins for the
duration of the project.

pounds per 1000 square feet (21 lbs./1000 sq.ft.), and mulching shall
consist of small grain straw applied a rate of 70 pounds per 1000
square feet (70lbs./1000sq.ft.). Mulch shall be anchored by roving or
netting.
END OF SECTION
Areas where no substantial or significant progress is made for more
than 15 days shall be temporarily seeded as shown on the Drawings and
specified herein. All areas must be seeded, mulched, and anchored
unless written approval is granted by the Owner. Incidental grading
--shall not constitute substantial or significant progress in construction- -- --- - ----
activity.
Seeding and mulching shall be done immediately following
construction. All disturbed areas shall be dressed to a depth of 8
inches. The top 3 inches shall be pulverized to provide a uniform
seedbed.
' Agricultural lime shall be applied at a rate of 95 pounds per 1000
square feet (95 lbs. /1000 sq.ft.) immediately before plowing.
Grass seed shall be applied at the following rate:
' Tyne Dates Possible Rate
Rye (Grain) Aug. 15 - Nov. 1 120 lbs./ac.
