Thank you for meeting with us last Friday. Despite any frustrations expressed at the
meeting, I believe that it was helpful in moving this matter forward to have a face-to-face
exchange to identify the issues left to resolve and to agree to a schedule for resolving those issues
and issuing the public notice.
As we discussed at the meeting, it is our plan to have the revised Stream and Wetlands
Mitigation Plan to you by this coming Monday, May 24, 1999. You indicated that you and your
staff would commit to an expedited review of the plan and preparation and review of the water
quality certification in time to allow the public notice to be to the Anson Record in time for the
June 8 publication. Their publication deadline generally is the Friday preceding the publication
date, so the notice will need to be to them during the week of May 31. Sherri Coghill and you
will work together during the next couple of weeks to draft a joint public notice for submission.
If you need assistance with the newspaper, please let us know. Steve Roberts of Chambers lives
in Wadesboro and has a very good relationship with the folks at the newspaper.
Based on the above schedule, we discussed July 12 or July 13 as dates for the hearing.
Before then, I would like to talk with you further regarding the process followed by the Division
of Water Quality at the hearing as it is different in some respects from Solid Waste's prcedures,
especially in terms of participation by the applicant. We will gladly follow your process, but want
to make sure that we have a complete understanding of what will be expected of
Chambers at the hearing.
We did not discuss the post-hearing process at the meeting on Friday, but we
obviously want the final certification to be issued as soon after the hearing as possible
fY1 since it must be issued before the wetlands permit and ultimately the landfill permit can

be finalized and issued. Although we understand that by regulation you can take up to 60 days
after the hearing to issue the final certification, we trust that you will finalize the document in a
much shorter time frame.
We look forward to working with you in the next couple of weeks to resolve any
outstanding matters and to have the draft water quality certification and public notice issued. If
there is anything that we can do to facilitate this process, please let me know.

Memorandum To: Cyndi Bell
From: Todd St. John
Subject: Anson County Landfill tream Mitigation Design
Anson County
I have conducted a very brief review of the stream mitigation design and offer
some comments:
1) The applicant appears to have designed the stream channel to carry a particular design
storm and not necessarily to represent a stream channel that would result from
natural channel forming hydraulics, etc. It does not seem reasonable that we require
the applicant to develop a regional curve at this point. However, based on the
available literature, I suggest that we ask the applicant to design the channel based on
the peak discharge from sediment basin outfall that would result from a two year
storm event. The two year storm duration should probably be based on a time of
concentration based on the peak runoff from "built out" watershed to the location of
the sediment basin out fall (i.e. as opposed to a 24 hour storm event). In addition, I
suggest that larger storm events be carried in a wide vegetated flood plain and not a
channel to better ensure stream bank stability.
2) It is of some concern that the only channel cross section provided on the plans, if
oriented in the same direction as indicated on the plans, seems to show armoring on
the "wrong" side of the channel.
3) The applicant has apparently not designed any part of the channel for carrying normal
flow. The cross section shows a four foot wide, flat stream bed. The stream bed
should be designed to carry normal flow in an appropriate channel with pools and
riffles to provide normal habitat for aquatic organisms. (The cross section still seems
to be a resemble a trapezoidal storm channel and not a natural stream channel. The
applicant should be requested to show enough cross sections to ensure that a proper
normal flow stream bed channel will be constructed with pool and riffle sequences as
appropriate.
4) The plans still call for herbaceous vegetation for a very broad portion of the channel
banks. More woody vegetation should be used.

STREAM AND WETLAND MITIGATION PLAN
ANSON COUNTY SOLID WASTE MANAGEMENT FACILITY
CHAMBERS DEVELOPMENT OF NORTH CAROLINA, INC.
WADESBORO, ANSON COUNTY, NORTH CAROLINA
1.0 INTRODUCTION
On behalf of Chambers Development of North Carolina, Inc. (Chambers), Almes & Associates,
Inc., Consulting Engineers (ALMES) has prepared this Stream and Wetland Mitigation Plan
(Mitigation Plan) for work related to the construction of the Anson County Solid Waste
Management Facility located near Wadesboro, Anson County, North Carolina.
Construction of the proposed landfill will result in the unavoidable fill of 0.49 acres of
jurisdictional wetlands including 1,084 feet of perennial stream. This Mitigation Plan revises the
March 1999 submittal(') to address specific comments in a May 7, 1999 memorandum from Mr.
John Dorney of the North Carolina Department of Environment and Natural Resources
(NCDENR), Division of Water Quality (DWQ) to Chambers. Issues in Mr. Domey's
memorandum outside the scope of this Mitigation Plan (related to landfill siting criteria,
stormwater management, or specific landfill facilities) were addressed by a May 14, 1999
response to DWQ.
This Mitigation Plan supercedes any previous submittals, including the May 15, 1998 draft
Wetland Mitigation Plan.
Although the North Carolina Solid Waste Section siting criteria make it very difficult to site a
modern landfill in Anson County without impacting any streams or wetlands, this plan minimizes
unavoidable impacts and provides compensation for those areas that will be impacted during
construction of the facility. Chambers will provide "on-site" mitigation for stream and wetland

County Solid Waste Management Facility, Wadesboro, Anson County, North Carolina" dated March 12, 1999.

impacts in lieu of making payments into the Wetland Restoration Fund or providing other forms of
off-site mitigation.
2.0 GOALS AND OBJECTIVES
This Mitigation Plan is the result of numerous conversations and field visits with both the U.S.
Army Corps of Engineers (Corps) and the DWQ. This plan provides details of the mitigation
work and is intended to satisfy the mitigation requirements of both agencies.
The goals and objectives of the proposed mitigation are as follows:
The wetland mitigation will provide at least twice as much wetland habitat (2:1 ratio) as
that which will be lost as a result of landfill construction. In addition to providing greater
surface area, it is anticipated that the replacement wetlands will provide a more diverse
habitat than what is currently available. The wetland will include wildlife desirable species
of vegetation for resting, feeding, nesting, and breeding habitat.
• The stream mitigation will restore a highly eroded and incised streambed into a more
natural configuration. The meandering stream system that will be constructed has been
designed to limit erosion and provide increased habitat for wildlife and benthic
macroinvertebrates. The stream mitigation will replace 1,084 linear feet of perennial
stream with approximately 1,300 linear feet of perennial stream.
3.0 GEOGRAPHIC LOCATION
The proposed landfill site is located off U.S. Route 74 between Polkton and Wadesboro, North
Carolina (refer to the Vicinity Map presented in Figure No. 1 and a U.S.G.S. Site Location Map in
Figure No. 2). The proposed landfill site is bordered to the south by the existing CSX Railroad
right-of-way, to the north and west by Brown Creek, and to the east by Pinch Gut Creek. All
drainage from the proposed landfill site eventually flows into either Brown Creek or Pinch Gut
1 -2-

Creek via numerous unnamed tributaries. The drainage patterns for surface water flows are shown
' on Figure No. 3 - General Site Layout map along with the property boundaries and other site
features. The streams and associated wetlands that will be impacted as a result of the proposed
landfill are also shown on the drawing.
' The proposed stream and wetland mitigation sites are located within an unnamed tributary to
Pinch Gut Creek located on the northeast side of the proposed landfill.
4.0 STREAMS
4.1 IMPACTED STREAM

The impacted stream is an unnamed tributary to Pinch Gut Creek. The middle and upper portions
of the impacted tributaries include wet weather channels and intermittent streams that carry
surface water during periods of heavy rain. The lower section of impacted stream is perennial
(typically flow year-round). Stream mitigation is required only for impacts to the perennial
stream.

L

During a February 4, 1999 field visit, Mr. John Domey of the DWQ determined the upper limits
of the perennial stream (refer to Appendix A for site photographs). The limits established during
the site visit were subsequently surveyed by Harrington & Associates P.A. during the week of
February 8, 1999. The total length of impacted perennial stream is 1,084 linear feet.
In general, the perennial stream to be impacted is deeply incised, has little to no bottom substrate
and is highly eroded along portions of the banks. This section of stream contains very little riffle,
run, and pool habitats that are typically associated with higher quality streams. Minimal benthic
macroinvertebrate life was observed within the stream most likely due to the lack of bottom
substrate and low flows. Stream measurements reveal an average stream bottom width between 2
to 4 feet. Refer to Section 4.3 for predevelopment and post-development peak flow rates.

As discussed in Section 4.0, the total length of impacted perennial stream is 1,084 feet. This area
includes the upper limit of the perennial stream (determined from the February 4, 1999 DWQ field
visit) downstream to the toe of the proposed embankment, which is located outside of the landfill
footprint (refer to Figure No. 3). The total stream mitigation is 1,300 feet and accounts for
potential impacts to that portion of perennial stream between the toe of the embankment and the
upstream limit of the existing wetland. This 180-foot section of stream may be impacted by the
diversion of flow into Sediment Basin No. 1 and has been included in this plan as a precautionary
measure.
During the February 4, 1999 field visit with John Dorney of DWQ, suitable sections of stream
channels were selected for stream mitigation. At that time, it was decided that certain stream
functions were deficient in these areas and that the selected sites would be suitable for mitigation.
The values and functions that the mitigated streams will replace and enhance those that currently
exist. The straight and narrow channels will be replaced by a more naturally meandering system.
Rocks from throughout the site will be used as substrate to provide habitat for the establishment of
benthic macroinvertebrate communities. The combination of seeding and planting along the banks
will not only increase existing vegetative diversity and reduce stream velocity, but also provide
increased bank stability, a feature that is currently lacking in the perennial stream that will be
impacted.
4.3 WATER BUDGET AND STREAM DESIGN
Surface water flow will provide the majority of water for the proposed mitigation site. The
upgradient drainage area includes approximately 127 acres that will flow into the mitigation area.
Sediment Basin No. 1, which is proposed to be located just above the mitigation area, will collect
and slowly discharge surface water from 94 of the 127 acres. The remaining 33 acres will be
direct runoff from adjacent "nondisturbed" areas. Based on water levels from nearby groundwater
-4-

monitoring wells, it is expected that groundwater will also contribute to the "water bi
stream and wetland.
A review of "Stream Corridor Restoration: Principles, Processes, and Practices"(') (Stream
Corridor Restoration Guidance) was conducted to determine the design for the relocated stream
channel. Chapter 8 of this document provides the following procedures for the preliminary new
channel design:
1. Describe physical aspects of the watershed and characterize the hydrologic response;
2. Considering reach and associated constraints, select a preliminary right-of-way for the
restored stream channel corridor and compute the valley length and valley slope;
3. Determine the approximate bed material size distribution for the new channel;
4. Conduct a hydrologic and hydraulic analysis to select a design discharge or range of
discharges; and
5. Predict stable planform type.
These 5 steps were performed for the stream reach in question, and a preliminary layout was
developed for the stream channel relocation. During this preliminary design stage, the physical
aspects of the post-development watershed to the relocated stream channel were evaluated and the
corresponding hydrologic response was determined. It was also during this preliminary design
stage that the design discharges were chosen. The peak discharge from the 25-year/24-hour storm
event for the contributing drainage area (including the sedimentation basin discharge) will be the
bankfull discharge and will be utilized to determine the bankfull channel design. The peak

discharge from the 100-year/24-hour storm event for the contributing drainage area will be the
discharge used to define the floodplain. The relocated channel planform was determined to be
meandering.

rl

I.

Following these 5 steps, one of three different approaches presented in ream Corridor
Restoration Guidance could be used to achieve the final design Approach as used for the
design of the relocated channel length. This approach detailed the following procedure:
• Compute mean flow, width, depth, and slope at design discharge;
• Compute or estimate flow resistance coefficient at design discharge;
• Compute mean channel slope and depth required to pass design discharge;
• Compute velocity or boundary shear stress at design discharge;
• Compute sinuosity and channel length; and
Check channel stability and reiterate as needed.
Following these steps, the channel layout and design provided on Figure 4 was determined. All
calculations for the determination of peak discharges under predev and post-development
conditions and channel sizing and stability were performed usin SEDCAD,(3) hydrology and
hydraulics analysis computer program. SEDCAD uses the SCS Techmca Release 55(4) (TR-55)
method to calculate stormwater runoff flows. Calculations for the computation of the design
discharge under predevelopment and post-development conditions for the stream design (peak
discharge for the 25-year/24-hour storm event and the 100-year/24-hour storm event) and
calculations for the channel design are provided in Appendix B. The calculations indicate that the
peak discharge to the existing stream channel from each of the respective design storm events
under predevelopment and post-development conditions is essentially equivalent to the peak
discharge to the relocated stream channel under post-development conditions for the same storm
1 event.

5.0 WETLANDS
5.1 IMPACTED WETLANDS
The wetlands to be impacted are located along the banks of the unnamed tributaries described
above. These wetlands provide some level of wildlife habitat; however, due to the sparse
vegetation, small size of the areas, and limited composition of vegetation, these areas are not
considered significant (in terms of providing food, cover, nesting, or resting habitats). Other
wetland functions, such as storage of floodwaters, nutrient cycling, groundwater recharge,
pollution filtration, etc. are probably being provided, but to a very limited or negligible degree.
Vegetation within the wetlands to be impacted consist of the following species:

Through prior conversations and field visits with the Corps, it was decided that an average width
of 5 feet along the impacted stream channels would be representative in determining the impacted
wetland acreage. This 5-foot average was then multiplied by the entire length of tributaries
affected by the proposed landfill development to calculate a total disturbed wetland acreage (refer
to Figure No. 3). The length of stream that was used to determine impacted wetland acreage not
only included areas adjacent to the perennial stream, but also areas adjacent to wet weather
channels and intermittent stream channels. A total of 0.49 acres of wetlands will be impacted as a
result of landfill construction.
There is an existing wetland upstream of the mitigation area that had been created as a result of the
construction of an access road. The metal culvert that serves as the outfall structure for the
-7-
.jAk

existing wetland is elevated above the bottom of the stream channel, thus creating an environment
suitable for the establishment of a wetland. There are no anticipated impacts to this wetland due to
rerouting surface water form the southwest tributary to the southeast tributary. The back flooding
effects of this saturated area will remain the same.
It should be noted that Chambers does not intend to develop, or in any way disturb, the high
quality forested or scrub/shrub wetlands located adjacent to Pinch Gut Creek or Brown Creek.
1 5.2 WETLAND MITIGATION

L'

Chambers proposes to mitigate for the loss of wetlands using a minimum 2:1 ratio. A minimum of
0.98 acres of wetlands will be created. This acreage does not include wetlands that will be created
along the banks of the mitigated stream.
The proposed mitigation site consists of a conifer upland forest (loblolly pine) located along an
unnamed tributary to Pinch Gut Creek. Due to its location, this area will be protected from future
development and will provide a buffer for downstream wetland ecosystems.
Soils within the mitigation area consist of Creedmoor Fine Sandy Loam (CrB) with 2 to 8 percent
slopes and Mayodan Fine Sandy Loam (MaB) with 2 to 8 percent slopes. The Creedmoor Fine
Sandy Loam soils are gently sloping, very deep, moderately well drained to somewhat poorly
drained on uplands. They have a loamy surface layer and a clayey subsoil. Permeability is very
low and shrink-swell potential is high. The Mayodan Fine Sandy Loam is also gently sloping and
very deep. They have a loamy surface layer and a clayey subsoil. Permeability is moderate and
shrink-swell potential is moderate. Seasonal high water table is below 6.0 feet.
6.0 CONSTRUCTION
Site grading by the contractor will be a critical factor in the success of this project. Ecological
Restoration, Inc. (ERI) (or similar highly qualified contractor) will grade the site and provide and
-8-

n
install all of the wetland plant materials. A summary of ERI's North Carolina wetland mitigation
and streambank stabilization experience is presented in Appendix C. The following sections
provide details of the stream and wetland construction. Refer to Figure No. 4 for the Site Grading,
Seeding and Planting Plan related to the stream and wetland mitigation.
1 6.1 SCHEDULE

I

1

The construction schedules for the landfill and wetland/stream mitigation will be dictated by the
timing and issuance of the 401, 404 and related landfill permits. To the extent possible, the
construction of the mitigation area will coincide with the construction of the landfill. While the
actual construction activities can occur simultaneously, the timing of the actual wetland plantings
may need to be staggered. To increase plant survivability, it is recommended that the majority of
wetland vegetation be planted in the early spring. Some species may be planted in the fall.
6.2 CLEARING AND GRUBBING
In order to maintain as much of a natural environment as possible, only select timber will be
removed from the immediate stream and wetland mitigation area. In general, full sunlight is
required for the establishment and growth of the vegetative species selected for this project. While
the removal of the majority of overstory trees is necessary, select trees will remain, at the direction
of the Wetlands Planner. The juxtaposition of trees, especially along the meandering streambank,
will add to the overall diversity and character of the project. All invasive species will be removed.
As shown on Figure No. 4, a 50-foot forested buffer will be maintained adjacent to the stream and
wetland mitigation areas.
6.3 EXCAVATION TO BASE GRADES
The contractor will excavate the stream channels to the base grades shown on Figure No. 4. For
the wetland area, the contractor will over-excavate soils within the wetland mitigation area to 6
1 9

F
inches below the final grades shown on Figure No. 4. This is required so that 6 inches of wetland
soils can be placed to achieve final grades (Section 6.4). A soil berm will be left in place between
the existing stream channel and the constructed stream channels and wetlands during construction
to prevent the inflow of water. Once the stream and wetland areas have been prepared and erosion
controls have been placed, the separation berms will be removed.
The wetland contractor is responsible for providing all surveying services related to:
' 1. Establishing the limits of the stream and wetland mitigation area;
2. Establishing all site grading; and
' 3. Establishing the limits of each vegetative zone within the wetland mitigation area.
A rectangular notch concrete weir will be constructed at the downstream end of the mitigated
' wetland. The outfall structure will maintain a standing water level within the wetland and will
' have a crest elevation of 244.5 feet. The wetland contractor will be responsible for constructing
the weir at the specified elevation, which will be verified in the field prior to construction.
6.4 PLACEMENT AND PREPARATION OF WETLAND SOILS

Soils from the existing wetlands (along the channels) are to be removed and stockpiled until the
grades within the wetland mitigation area have been established. The re-use of these soils within
the mitigation area will provide a "seed bank" for the germination and establishment of wetland
plants while also providing organic material for new plant material. If the wetland soils are to be
stockpiled (that is, they would not be directly excavated and transported to the mitigation area),
long, furrow-like stockpiles are recommended (no higher than 5 feet high) in order to prevent
composting which would kill any seeds within the soils.
The contractor will transport, place, and grade stockpiled wetland soils throughout the entire
wetland mitigation area according to the final grades shown in Figure No. 4. If required, off-site
-10-

f
I
soils containing at least 10 percent organic matter can be used to supplement, but not replace, on-
site wetland soils.
It will be critical for the site to be graded as specified. To a limited degree, the plantings can be
adjusted based on slight differences in grading; however, the plants within each zone have specific
water tolerances and too much or too little water would affect the survivability of individual-
1 plants.

6.5 BIOENGINEERING MATERIALS
Different bioengineering materials have been incorporated into the stream and wetland mitigation
project. The stream channels and edges of the wetland will be lined with a coir mat, which is
manufactured from coconut fibers. The coir mat functions as an erosion control blanket while also
providing a stable medium to support the growth and development of plants. The coconut fiber
material is natural, long lasting, and has high tensile strength. After approximately 7 years, the
coir mat biodegrades and the root systems of the plants become the primary stabilizing element.
Prior to the placement of the coir mat, the sideslopes of the stream channels will be seeded with
the bank stabilization seed mix as presented on Figure No. 4. Herbaceous plants along with the
shrubs and trees can be planted through the coir mat after it has been placed and anchored. U-
shaped wire staples (11 gage minimum, 6 to 12-inches long) or wooden stakes can be used to
anchor the matting to the ground.
Coir logs will also be incorporated into the stream channel around the bends and other areas prone
to erosion. The logs are typically 12-inches wide and 20-feet long and are made of the same
coconut fiber as the coir mat. The logs will be anchored in-place by wooden stakes.
Rocks from existing rock piles at the site will be used as bottom substrate and for erosion control
along the stream bends. In addition, piles of rocks will be placed within the wetland for
amphibian and benthic macroinvertebrate habitat.

The rerouted stream will enter the constructed wetland via an open pool of water, 2 to 3 feet deep,
at the upper end. The rock-lined pool will aid in the dissipation of flow from the stream into the
wetland. Upturned stumps from the adjacent logging operations placed just below the pool (root
mass facing upstream) will further aid in the dissipation of flow and will assist with the dispersion
of water throughout the wetland.
6.6 PLANTING. SEEDING AND MULCHING
The vegetation proposed for planting along the banks of the stream and within the wetland
mitigation area will reflect those species native to the area and previously identified within the
impacted streams and wetlands. Other species not observed at the site but known to significantly
benefit wildlife include common persimmon, winterberry, dogwood, etc. and have also been
incorporated into the design. A combination of seeding and planting is believed to be the best
approach for plant establishment and ultimate survivability.
In order to provide a high quality, diverse habitat, the mitigation site includes different areas that
will establish different types of vegetation. In general, emergent vegetation will become
established within soils that are inundated or saturated throughout most of the year while the
shrubs and trees will become established at a slightly higher elevation. The stream mitigation
incorporates different wetland plant species along its meandering stream banks that will eventually
become established and provide increased bank stability. The two species of willows specified for
this project are especially good for providing erosion control along stream banks. The wetland
planting and seeding tables are provided on Figure No. 4.
It is recommended that the wetland be planted in the spring between April and May or in the fall
between September and October.

6.6.1 Planting
For the wetland area, all plants will be installed within the zones shown on the plan drawing. The
limits of these zones will be surveyed and marked in the field. The surveyed limits will establish
the limits of each planting zone and provide a boundary for the wetland planters. Planting should
occur after the separation berms have been removed along the former stream so that specific
planting locations (as they relate to water depths) can be determined in the field.
Emergent vegetation, shrubs and trees will also be planted along the slopes of the stream channel.
The vegetation will be planted through the coir mat and will eventually provide bank stability and
habitat along the banks of the stream. The total number of plants that will be planted along the
stream banks will be determined at a later date by Chambers and the Wetlands Planner.
Plants within each zone will be planted in such a manner as to resemble the most natural setting
possible. Plants will be installed at the same depth in the ground which they were grown at the
nursery. Plants that need to be supported will be staked in the field. Tree shelters will be used for
those species of trees and shrubs prone to foraging by animals.
If the plants are to be stored for any length of time prior to planting, a temporary holding area will
be constructed to stage plants prior to installation. The holding area will be constructed out of 6-
inch by 6-inch landscape timbers draped with an impermeable liner. All water dependent plants
will be set into the lined area and saturated with water. In addition, netting will be hung above the
plants to reduce stress and loss of moisture from direct sunlight.
6.6.2 Seeding
Seeding within the mitigation area should be in accordance with the stream bank/wetland
stabilization seed mixture specified on Figure No. 4. A temporary ground cover within the seed
mix has been specified that will provide erosion control and cover until the wetland seeds can
-13-

germinate and become established. The ground cover seed mix will include rye grass and
lespedeza, both of which are annuals.

0

J
As stated in Section 6.5, seeding will be conducted prior to the placement of the coir mat. The
only areas that will not receive the seed mix are the bottoms of the stream channels and the open
water portion of the wetland.
6.6.3 Mulching
Mulch will be provided to all areas within the mitigation area, including the banks. Mulch
application will include 4,000 to 5,000 lb/acre grain straw (or equivalent cover).
1 6.7 WILDLIFE AMENITIES

17
I?
CII

Wildlife amenities such as duck boxes, bluebird boxes, and roosting trees will be incorporated into
the wetland mitigation area. In addition, several areas of downed trees or snags will be brought
into the wetland to provide cover and resting areas for reptiles and amphibians. Also, brush piles
may be placed in upland areas on the outside edge of the 50-foot forested buffer zone. The brush
piles will increase the overall diversity of habitats for birds and other wildlife species utilizing the
mitigation area.
7.0 MONITORING AND EVALUATION OF SUCCESS CRITERIA
A five-year maintenance and monitoring period will be conducted for the stream and wetland
mitigation area. Monitoring will be conducted every six months for the first two years after
construction and once a year for the following three years. The monitoring will be conducted in
accordance with the DWQ manual titled "Standard Operating Procedures Biological Monitoring"
and will include water quality information, biological monitoring and vegetative monitoring.

7.1 WATER QUALITY
Since Chambers will be monitoring water quality at the outflow of Sediment Basin No. 1 (which is
located directly upstream of the mitigation area) as part of the approved NPDES permit for the
landfill, it will not be necessary to "reanalyze" water flowing from the mitigation area. During
each post construction monitoring period for the stream and wetland mitigation areas; however,
Chambers will collect field measurements of water quality to include pH, conductivity, dissolved
oxygen, and temperature. Stream flows will also be recorded.
In addition, Chambers Water Quality Monitoring Plan (Solid Waste Permit Application) includes
collection and monitoring at four locations (two upstream and two downstream) within Brown
Creek and Pinch Gut Creek. Analysis will include metals, volatile organic compounds, and semi-
volatile organic compounds.
7.2 BIOLOGICAL MONITORING
Chambers will sample benthic macroinvertebrates during each monitoring period in accordance
with DWQ's, Biological Monitoring manual. Benthic data will be collected in the perennial
portion of the stream to be mitigated prior to any construction activities and will serve as the
"baseline" to compare subsequent biological monitoring events within the stream mitigation area.
7.3 VEGETATIVE MONITORING
During each monitoring period, vegetation will be inventoried to document plant species and
percent aerial coverage. Planted vegetation including bare root, plug and containerized stock will
be monitored to determine survivability.
The project will be deemed "successful" if the wetland mitigation area has at least 75 percent
coverage of herbaceous vegetation present in all areas showing such vegetation on the plans, with
at least 85 percent of that coverage being provided by hydrophytic species. However, it is
-15-

r
I"
acceptable if the species differ from those shown on the plans as long as those differing are not
undesirable or invasive species.
7.4 REPORTING
Monitoring reports will be submitted after each monitoring period and will contain information
related to water quality, biological monitoring and vegetative monitoring. The reports will also
discuss the success of the site at the time of the inspection and analyze the functions being
provided. Photographs of the mitigation areas will also be included in the monitoring reports
along with a written plan to correct any deficiencies identified during each monitoring phase.
In closing, we believe that this Mitigation Plan provides adequate compensation for unavoidable
stream and wetland impacts related to the landfill construction. If you have any questions, or
require any additional information, please call.
