INTRODUCTION
A. Purpose
This report presents the results of the 1995 aquatic macroinvertebrate and fish surveys
conducted by CZR Incorporated (CZR) for PCS Phosphate Company, Inc. (formerly Texasgulf Inc.) in
the upper Whitehurst Creek mitigation channel. This sampling is required as a condition of 401 Water
Quality Certification No. 2748 issued on 30 June 1992 to Texasgulf Inc. by the Division of
Environmental Management (DEM) of the North Carolina Department of Environment, Health, and
Natural Resources.
This is the fourth report in a series for upper Whitehurst Creek, and is the third report
on the aquatic macroinvertebrates and fish of the upper Whitehurst Creek mitigation channel. The first
report presented the baseline condition in historical upper Whitehurst Creek based on 1992 surveys by
DEM and CZR. The second and third reports presented the first-year and second-year conditions,
respectively, of the upper Whitehurst Creek mitigation channel based on 1993 and 1994 surveys by
CZR. This fourth report presents the third-year conditions of the upper Whitehurst Creek mitigation
channel based on CZR's 1995 surveys, and presents the recolonization to date based on the 1993 and
1994 surveys and updated with the 1995 survey results.
B. Project Site
A detailed description of the mitigation channel is found in Appendix B of the 1992
Baseline Report. The upstream end of the mitigation channel begins at the outlet of a sediment basin
' and continues for approximately 5,000 linear feet to join Whitehurst Creek on the west side of the
bridge on old SR 1941. The mitigation channel has a flat bottom approximately 10 feet in width and
2.5:1 side slopes. The slopes were vegetated with a mixture of Kobe lespedeza, German millet, and
Pensacola bahia grass in addition to various tree seedlings. Log/limb sections and leaf litter were added
' to selected spots. in the mitigation channel in April 1993.

II. METHODOLOGY
A. Macroinvertebrates
Two monitoring stations were established in the mitigation channel in 1993 for
surveying aquatic macro invertebrates. Station 1 is located above SR 1941 near the mouth of the
mitigation channel, and Station 2 is approximately half-way between SR 1941 and the sedimentation
pond (Figure 1). Sampling was conducted at these stations on 23 February 1995 and again on 12 July
1995. The sampling methodology is presented in the 1992 Baseline Report.
B. Fish
Two monitoring stations were established in the mitigation channel in 1993 for
surveying fishes. Each station consists of a 600-foot stretch of channel marked by stakes at the
starting-point, mid-point, and ending-point. These two 600-foot stretches incorporate the
macroinvertebrate monitoring stations described in Section ILA (Figure 1). Sampling was conducted
at these stations on 23 February 1995 and again on 12 July 1995. The fish sampling methodology is
presented in the 1992 Baseline Report.
C. Water Quality
Monthly water quality sampling and analyses were conducted by the PCS Phosphate
Environmental Affairs laboratory. These samples were collected from locations near the mouth and
near the middle stretch of the mitigation channel (Figure 2). Water samples were analyzed for
temperature, conductivity, dissolved oxygen, and pH while in the field , and for fluoride and total
phosphorus in the laboratory.

III. RESULTS
A. Macroinvertebrates
Water quality information and site descriptions collected during macroinvertebrate
sampling are presented in Table 1. A summary of macroinvertebrate taxa richness is provided in Table
2. The summary is presented by major taxonomic groupings, with insects divided into orders and other
invertebrates divided into classes. A breakdown of macroinvertebrate taxa included within each of
those groups along with relative abundances of the taxa within each sample is provided in Table 3.
Sixty-one macroinvertebrate taxa were identified from the upper Whitehurst Creek
mitigation channel during 1995 (Table 2), the third year after its construction. Fifteen of these taxa
were documented in historical upper Whitehurst Creek during the 1992 baseline surveys. Three of
these fifteen taxa were documented for the first time from the mitigation channel. Thirty-two of the
other forty-six taxa represent new additions to the fauna documented for Whitehurst Creek, with the
other fourteen taxa documented during the 1993 and 1994 mitigation channel surveys (Appendix A).
B. Fish
A summary of the 1995 seasonal fish surveys is presented in Table 4. Eleven species
were documented from the upper Whitehurst Creek mitigation channel during the third year after its
construction. Six of these species were among the nine fish species documented in historical upper
Whitehurst Creek during the 1992 baseline surveys. Four of these eleven species (dusky shiner, yellow
bullhead, banded killifish, and largemouth bass) represent new additions to the documented fauna
(Appendix B).

C. Water Quality
A summary of the monthly water quality analyses is presented in Table 5. This
summary includes data collected from September 1994 through December 1995.
D. Recolonization
A summary of the macroinvertebrate recolonization of the upper Whitehurst Creek
mitigation channel through February 1995 is presented in Table 6. A breakdown of macroinvertebrate
taxa included within each of the groups presented in Table 6 is provided in Appendix A.
Ninety-four macroinvertebrate taxa are shown as documented from the upper
Whitehurst Creek mitigation channel within the three years after its construction. The actual number
of species documented is higher since the taxa presented are broken down only to the taxonomic level
of effort initially established by DEM personnel during the winter 1992 baseline survey of upper
Whitehurst Creek. For example, since DEM identified taxa within the group Coleoptera only to the
generic level, the three species within the genus Tropisternus identified during the summer 1994 survey
were lumped within the taxon Tropisternus spp. established by DEM.
Representative taxa from ten of the eleven macroinvertebrate groups documented during
the 1992 baseline survey, as well as an additional group, have been documented as recolonizing the
upper Whitehurst Creek mitigation channel. The February 1995 survey included the addition of one
group (Oligochaeta) present in the baseline survey but not documented in the mitigation channel during
the first two years.
Seven of the nine fish species documented in the 1992 baseline survey, as well as five
additional species, have now been documented as recolonizing the upper Whitehurst Creek mitigation
channel (Table 7). Four new species of fish were documented in the 1995 surveys. The diversity and
number of individuals documented represent increases over previous winter mitigation channel surveys.

IV. SUMMARY
Sixty-one taxa of aquatic macro invertebrates were recorded in the 1992 baseline survey of
historical upper Whitehurst Creek, whereas 94 taxa have been documented in the 1993-1995 surveys
of the upper Whitehurst Creek mitigation channel. To date, 28 of the 61 taxa (or 45.9 percent) of
aquatic macroinvertebrates documented in the 1992 baseline survey have been documented within the
mitigation channel. An additional 66 taxa of aquatic macroinvertebrates not documented in the
historical upper Whitehurst Creek have been documented within the upper Whitehurst Creek mitigation
channel within the three years since its construction.
Seven of the nine species (or 77.8 percent) of fish documented in the 1992 baseline survey of
historical upper Whitehurst Creek have been documented within the upper Whitehurst Creek mitigation
channel. Four additional species of fish not documented in the historical upper Whitehurst Creek have
been documented within the upper Whitehurst Creek mitigation channel within three years since its
construction.

I. INTRODUCTION
A. Purpose
' This report presents the results of the 1995 aquatic macroinvertebrate and fish surveys
conducted by CZR Incorporated (CZR) for PCS Phosphate Company, Inc. (formerly Texasgulf Inc.) in
' the upper Whitehurst Creek mitigation channel. This sampling is required as a condition of 401 Water
Quality Certification No. 2748 issued on 30 June 1992 to Texasgulf Inc. by the Division of
Environmental Management (DEM) of the North Carolina Department of Environment, Health, and
Natural Resources.
This is the fourth report in a series for upper Whitehurst Creek, and is the third report
on the aquatic macroinvertebrates and fish of the upper Whitehurst Creek mitigation channel. The first
report presented the baseline condition in historical upper Whitehurst Creek based on 1992 surveys by
' DEM and CZR. The second and third reports presented the first-year and second-year conditions,
respectively, of the upper Whitehurst Creek mitigation channel based on 1993 and 1994 surveys by
CZR. This fourth report presents the third-year conditions of the upper Whitehurst Creek mitigation
' channel based on CZR's 1995 surveys, and presents the recolonization to date based on the 1993 and
1994 surveys and updated with the 1995 survey results.
' B. Proiect Site
A detailed description of the mitigation channel is found in Appendix B of the 1992
Baseline Report. The upstream end of the mitigation channel begins at the outlet of a sediment basin
and continues for approximately 5,000 linear feet to join Whitehurst Creek on the west side of the
bridge on old SR 1941. The mitigation channel has a flat bottom approximately 10 feet in width and
' 2.5:1 side slopes. The slopes were vegetated with a mixture of Kobe lespedeza, German millet, and
Pensacola bahia grass in addition to various tree seedlings. Log/limb sections and leaf litter were added
' to selected spots. in the mitigation channel in April 1993.

II. METHODOLOGY
A. Macroinvertebrates
Two monitoring stations were established in the mitigation channel in 1993 for
surveying aquatic macroinvertebrates. Station 1 is located above SR 1941 near the mouth of the
mitigation channel, and Station 2 is approximately half-way between SR 1941 and the sedimentation
pond (Figure 1). Sampling was conducted at these stations on 23 February 1995 and again on 12 July
1995. The sampling methodology is presented in the 1992 Baseline Report.
B. Fish
Two monitoring stations were established in the mitigation channel in 1993 for
surveying fishes. Each station consists of a 600-foot stretch of channel marked by stakes at the
starting-point, mid-point, and ending-point. These two 600-foot stretches incorporate the
macroinvertebrate monitoring stations described in Section ILA (Figure 1). Sampling was conducted
at these stations on 23 February 1995 and again on 12 July 1995. The fish sampling methodology is
presented in the 1992 Baseline Report.
C. Water Quality
Monthly water quality sampling and analyses were conducted by the PCS Phosphate
Environmental Affairs laboratory. These samples were collected from locations near the mouth.and
near the middle stretch of the mitigation channel (Figure 2). Water samples were analyzed for
temperature, conductivity, dissolved oxygen, and pH while in the field , and for fluoride and total
phosphorus in the laboratory.

Ill. RESULTS
A. Macroinvertebrates
Water quality information and site descriptions collected during macroinvertebrate
sampling are presented in Table 1. A summary of macroinvertebrate taxa richness is provided in Table
2. The summary is presented by major taxonomic groupings, with insects divided into orders and other
invertebrates divided into classes. A breakdown of macroinvertebrate taxa included within each of
those groups along with relative abundances of the taxa within each sample is provided in Table 3.
Sixty-one macroinvertebrate taxa were identified from the upper Whitehurst Creek
mitigation channel during 1995 (Table 2), the third year after its construction. Fifteen of these taxa
were documented in historical upper Whitehurst Creek during the 1992 baseline surveys. Three of
these fifteen taxa were documented for the first time from the mitigation channel. Thirty-two of the
other forty-six taxa represent new additions to the fauna documented for Whitehurst Creek, with the
other fourteen taxa documented during the 1993 and 1994 mitigation channel surveys (Appendix A).
B. Fish
A summary of the 1995 seasonal fish surveys is presented in Table 4. Eleven species
were documented from the upper Whitehurst Creek mitigation channel during the third year after its
construction. Six of these species were among the nine fish species documented in historical upper
Whitehurst Creek during the 1992 baseline surveys. Four of these eleven species (dusky shiner, yellow
bullhead, banded killifish, and largemouth bass) represent new additions to the documented fauna
(Appendix B).

C. Water Quality
A summary of the monthly water quality analyses is presented in Table 5. This
summary includes data collected from September 1994 through December 1995.
D. Recolonization
A summary of the macroinvertebrate recolonization of the upper Whitehurst Creek
mitigation channel through February 1995 is presented in Table 6. A breakdown of macroinvertebrate
taxa included within each of the groups presented in' Table 6 is provided in Appendix A.
Ninety-four macroinvertebrate taxa are shown as documented from the upper
Whitehurst Creek mitigation channel within the three years after its construction. The actual number
of species documented is higher since the taxa presented are broken down only to the taxonomic level
of effort initially established by DEM personnel during the winter 1992 baseline survey of upper
Whitehurst Creek. For example, since DEM identified taxa within the group Coleoptera only to the
generic level, the three species within the genus Tropisternus identified during the summer 1994 survey
were lumped within the taxon Tropisternus spp. established by DEM.
Representative taxa from ten of the eleven macroinvertebrate groups documented during
the 1992 baseline survey, as well as an additional group, have been documented as recolonizing the
upper Whitehurst Creek mitigation channel. The February 1995 survey included the addition of one
group (Oligochaeta) present in the baseline survey but not documented in the mitigation channel during
the first two years.
Seven of the nine fish species documented in the 1992 baseline survey, as well as five
C
additional species, have now been documented as recolonizing the upper Whitehurst Creek mitigation
channel (Table 7). Four new species of fish were documented in the 1995 surveys. The diversity and
number of individuals documented represent increases over previous winter mitigation channel surveys.

IV. SUMMARY
Sixty-one taxa of aquatic macroinvertebrates were recorded in the 1992 baseline survey of
historical upper Whitehurst Creek, whereas 94 taxa have been documented in the 1993-1995 surveys
of the upper Whitehurst Creek mitigation channel. To date, 28 of the 61 taxa (or 45.9 percent) of
aquatic macroinvertebrates documented in the 1992 baseline survey have been documented within the
mitigation channel. An additional 66 taxa of aquatic macroinvertebrates not documented in the
historical upper Whitehurst Creek have been documented within the upper Whitehurst Creek mitigation
channel within the three years since its construction.
Seven of the nine species (or 77.8 percent) of fish documented in the 1992 baseline survey of
historical upper Whitehurst Creek have been documented within the upper Whitehurst Creek mitigation
channel. Four additional species of fish not documented in the historical upper Whitehurst Creek have
been documented within the upper Whitehurst Creek mitigation channel within three years since its
construction.

Dear Gentlemen:
With the amount of dry weather that we have been having, the excavation of the Bailey
Creek relocation channel is progressing rapidly. However an unanticipated problem has
arisen as we approach the western tie-in point. The existing channel comes very close
to the top of the slope of the relocated channel, and there is no room in this area to
push the spoil.
We have designed a solution to this problem, and it is shown in the attached figure.
We propose to construct a temporary diversion channel west and north of the existing
Bailey Creek channel to reroute the water flow, and fill in a section of the existing
channel to allow spoil placement. This diversion channel would include two rock check
dams and a settling basin before it reconnects with the Bailey Creek channel.

We request your review and approval of this construction detail as soon as possible so
that we can complete the relocation during this good weather. If you have any
questions, please call me at 919/322-8249.
Sincerely,

Phosphate AURORA DIVISION
P.O. BOX 48, AURORA, NC 27806
May 28, 1996
Mr. John, Dorney
Water Quality Section
Division of Environmental Management
North Carolina Department of EHNR
4401 Reedy Creek Road
Raleigh, North Carolina 27607
Dear Mr. Dorney:
On December 15, 1995, PCS Phosphate applied for a 401 Water Quality Certification for
impacts to the upper channelized drainage to Bailey Creek. In the cover letter for that
application, we also requested that certain conditions in the 401 Certification for Whitehurst
Creek (dated June 30, 1992) be deleted. These conditions involved the requirement for
reclamation of Whitehurst Creek within 4 years from the date of mining the fork of the two
drainage prongs and a $1,000 per day penalty if it was not reclaimed by then. We also
outlined a modified reclamation plan for the whole southern mining area encompassing the
Whitehurst and Bailey Creek drainages, and a map of this plan was provided. We agreed at
the time that the Bailey Creek 401 would be the issue of priority for DEM to focus on. Now
that the 401 Certification for Bailey Creek has been approved, the Whitehurst Creek issue
needs to be addressed.
At the time of the issuance of the initial 401 Certification for Whitehurst Creek (June 1992),
it was believed that the restoration of the upper channelized drainage to Whitehurst Creek
could be accomplished within the 4-year time frame stipulated in the permit. We believed that
we were close to completing the EIS process that had begun in 1988. However, the EIS
process is still not completed, which has caused PCS Phosphate to request three additional
modifications to our mining permit to continue mining in upland areas in the southern portion
of our property. As long as mining activities continue in this southern area, the mine utility
corridor (2 canals, pipelines and road) needs to remain in place near the old S. R. 1941 bridge,
which precludes tieing-in'a reclaimed channel to the main Whitehurst Creek channel. We
project that this corridor will need to remain much longer than anticipated when the Whitehurst
Creek 401 Certification was agreed to (Figure 1).
In the December 15, 1995 letter, a proposal was put forth to create one channel for Whitehurst
Creek through reclaimed land and to also let the current Whitehurst Creek mitigation channel
remain in place permanently. This makes the most ecological sense based on the direction that
stormwater would flow off the reclaimed land, and would result in approximately 8,200 feet
of restored channel compared to a currently required 5,000 feet. We believe that there is no
reason to not use the mitigation channel that is already in place and is functioning better than
the original channel for part of the permanent reclamation of this area.
Mr. John Dorney
May 28, 1996

We still are proposing that scenario, however we propose to modify the design of the channel
constructed through reclaimed land to be similar to the design recently approved for the
relocation of Bailey Creek. That is, there will be an approximately 50-foot wide floodplain
slightly elevated along each side of a 10-foot wide channel. This will result in approximately
7 acres of bottomland hardwood wetland, which did not originally exist. Enclosed are large
drawings which show the design of the reclaimed channel and the overall reclamation plans
for the area. The construction of the channel through reclaimed land would be accomplished
in two phases. The first phase of constructing the main portion of the channel would be done
by April 1998. The second phase would be tieing-in the new channel to the original channel,
which would be done by April 2003. This timing is outlined in Figure 2. Notice that the total
delay in the restoration of Whitehurst Creek is 5 years, which equals the amount of time that
we will have mined in this area over what we originally believed we would. For this reason,
we request that the condition in the original 401 Certification that the restoration of upper
channelized drainage to Whitehurst Creek be completed within the 4-year time frame (by June
1998) be modified to reflect the 5-year delay and specify restoration by June 2003. In
addition, we request that the $1,000 per day penalty condition be dropped since the existing
Whitehurst Creek mitigation channel equals the total length of the original channelized drainage
and is functioning better than the original channel.
A table highlighting the benefits of the new plans for Whitehurst Creek is also enclosed. If
you have any questions on this request, please call me at 919/322-8249.
Sincerely,
Jeffrey C. Furness

AURORA DIVISION

Mr. Steve Tedder, Chief
Water Quality Section
Division of Environmental Management
North Carolina Department of EHNR
P. O. Box 29535
Raleigh, North Carolina 27626-0535
Dear Mr. Tedder:
PCS Phosphate has applied to the Division of Land Resources to
modify its mining permit by adding 770 acres to the existing
permitted acreage. This modification is necessary to allow PCS
Phosphate to continue mining while the Environmental Impact
Statement process is continuing. A small portion of this 770-acre
area includes a segment of the upper channelized drainage to Bailey
Creek. A No. 26 Nationwide Permit application has been submitted
to the Corps of Engineers to impact approximately 0.3 acres of
"Waters of the U. S." in the channel itself. It is estimated that
"Waters of the State" would be less than one acre and, therefore,
7 copies of an application for a 401 Water Quality Certification
are enclosed.
Included with each application is a reclamation plan and several
drawings that relate to this permit request. PCS Phosphate
proposes to permanently relocate a segment of this channelized
drainage to Bailey Creek to the perimeter of the mining area prior
to impacting the existing channel. This channel relocation plan is
outlined in the enclosed reclamation plan and detailed in the
enclosed drawing titled "Construction Plan for the Relocated
Channel for the 770 Acre Mine Block."
Also enclosed with this application is a large drawing titled
"Reclamation Plan for the 770/290/360/700 Acre Mine Blocks". This
drawing visually depicts what the narrative reclamation plan
describes. Because of the necessity to continue mining in this
southwest area long after PCS had hoped to be mining in the eastern
tract, plans for reclaiming this site are required to be altered
from those previously approved.

As long as mining activities continue in this southern area, the
mine utility corridor (2 canals, power line, pipelines and road)
needs to remain in place near the old S . R. 1941 bridge. This means
that any Whitehurst Creek channel constructed in reclaimed land
could not be tied-in to the existing lower channel until the
utility corridor is no longer required. Therefore we request that
the conditions that Whitehurst Creek be restored to its original
location within four years after mining through the junction of the
two prongs and the penalty of $1,000 per day if it is not restored
in four years, be deleted from Water Quality Certification 2748,
which was issued on June 30, 1992.
As can be seen from the large reclamation map, we propose to create
one channel for Whitehurst Creek through reclaimed land and to also
let the current Whitehurst Creek mitigation channel.remain in place
permanently. This makes the most ecological sense based on the
direction that stormwater would flow off the reclaimed land, and
would result in approximately 7,600 feet of restored channel
compared to a currently required 5,000 feet. We believe that there
is no reason to not use the mitigation channel that is already in
place and functioning better than the original channel for part of
the permanent reclamation of this area.
Thank you for your assistance in
