RE: Addendum to mining.Permit No. 7-01
Lee Creek Mine
Beaufort County
Dear Mr. Schimming:
This office has reviewed your letter of February 5, 1993 to
Mr. Tracy Davis concerning your questions, concerns and recommended
changes to the recently issued renewed and modified mining permit
for this site. This letter is to address your concerns in the
order that they were outlined in your letter: a
1) The disturbance limit in the cover letter attached to the
permit is a standard procedure this office follows to
advise the regional office staff and permittee of the
amount of land that can be disturbed at any one time. In
the case of your particular operation, this limit is not
appropriate and, therefore, is hereby eliminated. The
primary information in the cover letter is that your
company has 9,520 acres under Mining Permit No. 7-01.
2)' The July 14, 1988 reference in this mining permit is
hereby eliminated to avoid confusion.
3) All references made to previous permit modifications
outlined on pages 3 and 4 of the mining permit are for
historical documentation only. Whether or not these
activities have been completed, they are not part of the
operating or Reclamation Conditions of the mining permit.
4) The term "visibly marked" was used to require your
company to mark the boundaries of any wetland areas
within the mining permit boundary in such a way that both
your company personnel and our regional office staff

could easily determine the location of such a boundary.
This office did not want to restrict your company as to
the specific method to provide such marking. Some
suggestions are stakes with red or white painted tips,
flagging and painted marks on trees.
5) This office concurs with your proposed changes to the
wording for Operating Condition No. 4.D.1. The entire
Operating Condition No.' 4.D.1. shall read as follows:
"that the predisturbance flow levels of Whitehurst Creek
be maintained by pumping groundwater into the uppermost
portion of the creek at a rate to attempt to match the
pre -mined, undisturbed hydrology of the creek. This
requirement should maintain the aquatic life in the creek
and maintain the natural salinity levels at the mouth of
Whitehurst Creek at South Creek. In order to assure flow
into the mitigation channel during low runoff flow, a
water source shall be constructed adjacent to the
sediment pond and shall discharge directly into the
sediment pond near the upstream end. The water source
shall be controlled by a float switch located within the
sediment pond and set to maintain the water level so that
any runoff flow into the sediment pond will create an
immediate discharge into the mitigation channel."
6) This office hereby agrees that Operating Condition No.
4.D.4. should be modified as a large portion of the
condition has already been completed and no longer
applies. Therefore, Operating Condition No. 4.D.4. shall
read as follows:
"that the construction of the mine utility corridor
around the 700 acre expansion area shall be in accordance
with the above approved plans and corresponding permits.
Furthermore, adequate erosion and sedimentation control
measures shall be installed and maintained downstream of
any land disturbing activity related to the construction
of the mine utility corridor, most specifically in those
areas where water may flow directly into the headwaters
of Whitehurst Creek."

µ Mr. �Schimming
March 10, 1993
Page 3
7) This office hereby changes the wording of Operating
Condition No. 6.B. to the following as per your request:
"Up to the first fifty (50) feet of overburden shall be
removed by a bucket wheel excavator system and conveyed
to previously mined areas for reclamation. The remaining
overburden shall be removed by draglines and cast into
previously mined areas in windrows."
8 ) This office concurs with the proposed change to Operating
Condition No. 6.C. The new condition shall read as
follows:
"Oversized phosphate pebbles and gangue materials
(rejects) in the ore matrix shall either be stockpiled in
the vicinity of the mill area or returned to a previously
mined area. This material may be utilized for internal
road construction and maintenance. It may also be made
available to the general public as well as state and
local governments."
9) This office concurs that the current wording of Operating
Condition No. 6.E. may prohibit the approved clay capping
of the R-2 blend area as well as the possibility of
pumping clay only into the ponds while the blend process
is inoperable. Therefore, in light of the above,
Operating Condition No. 6.E. shall read as follows:
"The clay material from the ore matrix shall be pumped to
the previously mined areas for backfill, either alone or
in a blend with gypsum. Clay only discharges shall not
exceed 25% of the total time of any waste discharges into
previously mined areas. Records documenting the amount
of time of clay vs. clay/gypsum blend discharges into
mined areas shall be maintained at the mine office and be
available for review by Department personnel upon
request."
10) This office has contacted Mr. Roger Thorpe with the
Division of Environmental Management regarding your
proposed change to Operating Condition No. 6.F. to allow
solids from cleaning the cooling ponds or associated
ditches to be pumped to the gypsum stockpile area. As
Mr. Thorpe foresees no problem with this activity,
operating Condition No. 6.F. shall be rewritten as
follows:

Mr. Schimming
March 10, 1993
Page 4
"The gypsum byproduct used in the clay/gypsum blend shall
be stockpiled next to the processing plant in no more
than a three stockpile rotation. Solids from cleaning
the cooling ponds or associated ditches may be pumped to
either the Number 1 or Number 2 gypsum stack."
11) This office concurs with your addition to Operating
Condition No. 8 and said condition shall now read as
follows:
"A physical barrier shall be maintained at all times
around the perimeter of any highwall to prevent
inadvertent public access. Examples of such barriers
could include vegetated earthen berms, canals or gates."
12) The two year time frame stated in the recently issued
permit for final reclamation is taken from G.S. 74-56 of
the Mining Act (Act). However, as stated by the Act,
such time frame for final reclamation can be "...longer
if authorized by the Department, ..." In light of the
fact that this office has approved your site specific
reclamation schedule, this office hereby modifies Minimum
Standard No. 6 to read as follows:
"Permittee shall conduct reclamation activities pursuant
to the Reclamation Plan herein incorporated. These
activities shall be conducted according to the time
schedule included in the plan, which shall to the extent
feasible provide reclamation simultaneous with mining
operations and in any event, provide reclamation at the
earliest practicable time after completion or termination
of mining on any segment of the permit area and shall be
completed within two years after completion or
termination of mining except for the, surfsces of glay and
gypsum wastes,_ for which gecl=ation g all follow the
schedule specified by this permit."
13) This office concurs that Reclamation Condition No. 2.A.
shall read as follows:
"Reclamation of mined land and settling ponds shall be
accomplished in two phases: 1) physical restoration and
2) revegetation. Physical restoration shall be
accomplished by 1) backfilling with bucket wheel
excavator (overburden) material and dragline cast
material, 2) backfilling with sand tailings from the

Mr .u�Schimming
March 10, 1993
Page 5
flotation section of the mill, 3) backfilling with
clay/gypsum blend, and 4) may include capping the top
surface with a clay cap to enhance the establishment of
vegetation."
14) This office concurs that Reclamation Condition No. 2.C.
shall read as follows:
"Rehabilitation of the clay settling ponds at or
associated with Texasgulf, Inc.'s mining operation shall
include the desiccation of water from the surface of the
ponds by the installation of drainage ditch systems.
Such drainage systems, in addition to establishing
vegetation including tree plantings, should aid in the
consolidation of the clays in the ponds. Reclaimed clay
ponds 1 thru 4B may be utilized as wildlife habitats,
forestry areas, or agricultural areas. Clay ponds 5A and
5B may be utilized as wetland habitats, as well as other
wildlife habitat. In any event, the final contours of
the surface of the clay ponds shall be in accordance with
the Final Reclamation Estimated Contours - Charles Tract
map dated October 21, 1992."
15) This office hereby changes Reclamation Condition No. 2.E.
to address your concerns:
"All settling ponds and sediment control basins used for
sedimentation control shall be backfilled, graded and
stabilized or cleaned out and made into acceptable lake
areas after such ponds and basins are no longer needed
for sedimentation control."
16) This office acknowledges your proposed change to
Reclamation Condition No. 2.F. and hereby changes the
condition to read as follows:
"The processing, stockpile, and other disturbed areas
neighboring the mine excavations shall be graded to
slopes no steeper than a 4 horizontal to 1 vertical."
17) This office concurs with your request to eliminate the
first sentence of Reclamation Condition No. 2.H. of the
permit. Therefore, the condition shall now read as
follows:
"On -site disposal of waste shall be in accordance with
Operating Condition No. 11.A. and B. of this permit."

APPROVED RECLAMATION PLAN
The Mining Permit incorporates this Reclamation Plan, the
performance of which is a condition on the continuing validity of
that Mining Permit. Additionally, the Reclamation Plan is a
separable obligation of the permittee, which continues beyond the
terms of the Mining Permit.
The approved plan provides:
Minimum Standards As Provided By G.S. 74_53
1. The final slopes in all excavations in soil, sand, gravel
and other unconsolidated materials shall.be at such an angle
as to minimize the possibility of slides and be consistent
with the future use of the land,
2. Provisions for safety to persons and to adjoining property
must be provided in all excavations in rock.
3. All overburden and spoil shall'be left in a configuration,
which is in accordance with accepted conservation practices
and which is suitable for the proposed subsequent use of the
land.
4. No small pools of water shall be allowed to collect or
remain on the mined area that are, likely to become noxious,
odious or foul.
5. The revegetation plan shall conform to accepted and
recommended agronomic and reforestation practices as
established by the North Carolina Agricultural Experiment
Station and the North Carolina Forest Service.
6. Permittee shall conduct reclamation activities pursuant to
the Reclamation Plan herein incorporated. These activities
shall.be conducted according to the time schedule included
in the plan, which shall to the extent feasible provide
reclamation simultaneous with mining operations and in any
event, provide reclamation at the earliest practicable time
after completion or termination of mining on any segment of
the permit area and shall be completed within two years
.after completion or termination of mining.

Page 13 of 16
RECLAMATION CONDITIONS:
1. Provided further, and subject to the Reclamation Schedule,
the planned reclamation for the 1993-2003 permit period
shall be: 1) backfill the mine excavations to original
elevation or higher except in those areas where approved
wetlands mitigation projects are required (the final
elevations may be below original surface elevations), 2)
stabilize all waste disposal areas and settling ponds, and
3) regrade and revegetate any areas in unconsolidated
material.
2. The specifications for surface gradient restoration to a
surface suitable for the planned future use are as follows:
A. Reclamation of mined land and settling ponds shall be
accomplished in two phases: 1) physical restoration
and 2) revegetation. Physical restoration shall be
accomplished by 1) backfilling with bucket wheel
excavator (overburden) material and draglin4 cast
material, 2) backfilling with sand tailings from the
flotation section of the mill, 3) backfilling with
clay/gypsum blend, and 4) capping the top surface with
a clay cap to enhance the establishment of vegetation.
B. Upon completion of the backfilling activity noted in
2.A. above, the surface shall be graded to the desired
final contours as indicated on the Final Reclamation
Contours - Mine and Plantsite map dated October 21,
1992.
C. Rehabilitation of the clay settling ponds at or
associated with Texasgulf, Inc.'s mining operation
shall include the desiccation of water from the surface
of the ponds by the installation of drainage ditch
systems. Such drainage systems, in addition to
establishing vegetation including tree plantings,
should aid in the consolidation of the clays in the
ponds. These reclaimed clay ponds shall be utilized as
wildlife habitats (i.e., fresh water wetlands) or,
through extensive research, may be determined suitable
as agricultural or forestry areas. In any event, the
final contours of the surface of the clay ponds shall
be in accordance with the Final Reclamation Estimated
..Contours - Charles Tract map dated October 21, 1992.

Page 14 of 16
D. Every six (6) months Texasgulf, Inc. shall submit to
the Department detailed reports of reclamation
activities and reclamation research for each of the
following areas:
1) Charles Tract clay waste areas
2) Clay -gypsum blend areas
3) Gypsum stockpile areas
4) Sand tailings areas
5) Other areas
Each report shall include a specific plan and schedule
for future reclamation and reclamation research.
E. All settling ponds and sediment control basins used for
sedimentation control shall be backfilled, graded, and
stabilized or cleaned out and made -into acceptable lake
areas.
F. The processing, stockpile, and other disturbed areas
neighboring the mine excavations shall be leveled and
smoothed.
G. Compacted surfaces shall be disced, subsoiled`or
otherwise prepared before revegetation.
H. No contaminants shall be permanently disposed of at the
mine site. On -site disposal of waste shall be in
accordance with operating Condition 11 A and B.
I. The affected land shall be graded to prevent the
collection of noxious or foul water.
3. ey_&getatj_on Plan:
Disturbed areas at the site shall be permanently revegetated
according to the following Revegetation Plan approved in the

For details see attached map AOG-049-173A
Phase I- Weed Control
The eastern most section of Pond Number 1 will be prepared
for weed control. High flotation tractors with wide tires will
be used to walk down the vegetation. When new tender vegetation
grows back, a herbicide will be used to kill it.
Phase II - Disk Plow and Bedding for Tree Planting
Once the vegetation has been killed from the herbicide
application, the upper one foot will be turned under by using a
special disk plow. This will aid in drying the surface and also
mix organic material in the upper one foot.
When the plowed area has had ample time to dry, a levee
plow will be used to establish mounds for tree planting.
Phase III - Tree Planting
No activity in this area.
Surface Drainage
Surface drainage ditches will be established in the eastern
most section of the Number 1 Pond. This will complete the
planned drainage of this pond. Approximately 83,000 feet of
ditches will be established in Ponds Number 2, 3, 4A, and 4B.
Approximately 16,000 feet of existing ditches in Ponds Number 3
and 4A will be cleaned out.

Surface Drainage
New surface drainage ditches were constructed across the
western portion of the area. This was accomplished by using a
high flotation tractor with a rotary ditcher attachment.
All of the existing surface ditches and major drainage
ditches were cleaned out and deepened to enhance drainage.
Development for Tree Planting
A portion of the area on the east end was disk plowed for
the first time. The standing vegetation was turned under by
using a special disk plow. This will assist in the drying
process as well as add organic matter to the upper one foot of
material.
Agricultural Row Croo Area
Alfalfa, planted on approximately 60 acres in the center
portion of the area is growing extremely well. This will develop
a nitrogen base in the soil.

Under the direction of Mr. Henry Riddick, Beaufort County
Extension Director, several test plots have been planted with the
following species;

Tree Planting Test Area
Dr. Steve Broome with NCSU is continuing to run tests on
different tree and plant species. This is a continuing research
project.

R-2 Area
An experiment was conducted on a small portion ❑f R-2
designed to test the feasibility of evenly distributing a
sand/clay blend cap over this reclaim area. The test results
indicated severe sand/clay separation at the discharge point,
therefore this approach to blend reclaim pond capping was
abandoned.
However, based on improved tree growth observed on the
planted clay disposal ponds as well as a wider species
adaptability, a plan was developed using by-passed mill clays as
a blend area capping material. This plan calls for a minimum of
18 inches of settled mill clays to be stage filled over the blend
surface via a network of perimeter gravity flow ditches. This
plan was presented to the Division of Land Resources for
approval, and was approved on June 2, 1992.
NCSU Test Plot Area
NCSU, under the direction of Dr. Broome has established
several test plots on the south side of the area. Several
grasses, legumes, and small grain plots have been planted and are
doing very well. This is a continuing research project.
Porter Creek Development
Three areas on mined over land along Porter Creek were
planted with a variety of hardwood trees. The species were
cypress, green ash, and sycamore. A total of 18 acres were
planted.

Surface Drainage
Surface drainage ditches will continue to be developed
throughout the southwestern portion of the area. This will
complete the initial drainage of R-1.
First Stage_ Development
Several areas will be disk plowed, allowed to dry, and disk
harrowed to establish a good textured soil. Once this has been
accomplished, alfalfa will be planted as a winter cover crop and
to establish a nitrogen base in the soil.
Agricultural Test Area
Rotating row crop plantings will continue in this area.
In the fall, small grain such as wheat, oats, barley, and canola
will be planted behind the harvest of the corn and soybeans.
Tree Plantina
No activity in this area.
R-2 Area
Clav Capping Project
A perimeter ditch will be constructed around 2/3 of the
area with decant slots every 500 feet. By-pass mill clays will
be discharged into the perimeter ditch and directed to different
areas of R-2 through the slots. Prior to any discharge of clays,
a network of surface drainage ditches will be established. These
ditches will enhance surface water run-off, and after the filling
is complete, will cause a depression that will later become a
permanent drainage ditch.
Blend Discharge
Blend discharge will be directed into R-3.

Dear Mr. Schimming:
Charles H. Gardner
Director
The review has been completed on your modification request dated
October 12, 1990 to remove the last sentence of Operating Condition No.
7.B.4. which requires your company to develop and submit a plan by 1992
to blend all new clays and gypsum directly at the plants for permanent
waste disposal/reclamation.
As this office concurs that your company's current program of using
a three pile gypsum stack rotation is working successfully and is the
best technique for continued operation into the future, I hereby approve
your request provided that no new gypsum stacks are constructed.
Attached is a copy of this revised page 6 of Mining Permit No. 7--01
which contains the modified Operating Condition No. 7.B.4. Please
replace the existing page 6 of your permit with this modified page 6 for
future reference.
In regards to your company's intentions to place a cap of
approximately one to three feet of a 4/sand to 1/clay mixture on the top
of the R-2 Blend Pond for reclamation, please be advised that you must
file a justification for such activity and receive this office's
approval prior to capping R--2 with the sand/clay mixture. As you may
recall, Dr. Woodhouse had some reservations about this idea, as do I. I
recommend that only a section of R-2 be capped as a test, rather than
the entire pond, and request that you contact me directly when this
experiment takes place.

RE: Mine Utility Corridor Revision - 700-acre Expansion
Lee Creek Mine
Mining Permit No. 7-01
Beaufort County
Dear Mr. Furness:
This letter is in response to your letter to me dated July 17,
1992 and to confirm, in writing, the approval I granted to you
during our July 17, 1992 telephone conversation regarding the above
matter.
Your request has been approved to place a 30-inch culvert in
each of the uncut lead ditches and for the subsequent placement of
coarse granular washer reject material over said culverts to allow
equipment access to the mine utility corridor area along the
perimeter of the 700-acre mine expansion. The fact that the lead
ditches are heavily vegetated, existing rock check dams are located
at the end of each lead ditch (before they combine to form the
headwaters of Whitehurst Creek), and you will place and maintain
silt fence at the toe of the reject material at each culvert
location, this office feels that this procedure will fulfill your
requirements to allow water to continue to flow to Whitehurst Creek
without causing sedimentation.
For your information, the Land Quality Section has received
and is currently reviewing your renewal and modification request
for this site. However, to date, this office has not received a
formal letter and major modification fee to address the changes
made in the 700-acre expansion plan as a result of the recently
issued 401 Water Quality Certification. Please forward these
documents as soon as possible to Mr. Tracy Davis so they can be
incorporated in your renewal and modification package.

RE: Modification Request - Development Plan for the Mine Utility Corridor
around the 700-acre Modification Area
Lee Creek Mine
Mining Permit No. 7-01
Beaufort County
Dear Mr. Schimming:
This office has completed its review of your request to modify the above
referenced mining permit to allow the development of the mine utility
corridor around the 700-acre modification area. This is proposed to be
accomplished by leaving four (4) gaps in the perimeter canal system to permit
water to continue to flow through the existing lead ditches into the
headwaters of Whitehurst Creek.
As the Division of Environmental Management has recently issued a 401
Water Quality Certification for the 700-acre modification area, your request
is hereby approved, as indicated in your letter to me dated May 12, 1992 and
corresponding Pre Mining Development To Meet Mining Schedule plan dated May
7, 1992, including approval to construct the entire utility corridor without
the proposed gaps, provided that the following stipulations are met:
1.) all conditions and requirements specified in the 401 Water Quality
Certification (No. 2748) issued June 30, 1992 by the Division of
Environmental Management shall be followed.
2.) adequate erosion and sedimentation control measures shall be
installed and maintained downstream of any land disturbing activity
related to the construction of the mine utility corridor, most
specifically in those areas where water may flow directly into the
headwaters of Whitehurst Creek.

APPROVED FMAMATION PLAN
The Mining Permit incorporates this Reclamation Plan, the performance of
which is a condition on the continuing validity of that Mining Permit.
Additionally, the Reclamation Plan is a separable obligation of the
permittee, which continues beyond the term of the Mining Permit.
The approved plan provides:
Minimum Standards As Provided By G. S. 74-53
1. The final slopes in all excavations in soil, sand, gravel and other
unconsolidated materials shall be at such an angle as to minimize
the possibility of slides and be consistent with the future use of
the land.
2. Provisions for safety to persons and to adjoining property must be
provided in all excavations.
3. All overburden and spoil shall be left in a configuration which is
in accordance with accepted conservation practices and which is
suitable for the proposed subsequent use of the land.
4. No small pools of water shall be allowed to collect or remain on
the mined area that are, or are likely to become noxious, odious or
foul.
5. The revegetation plan shall conform to accepted and recommended
agronomic and reforestation practices as established by the N.C.
Agricultural Experiment Station and the N.C. Forest Service.
6. Permittee shall conduct reclamation activities pursuant to the
Reclamation Plan herein incorporated. These activities shall be
conducted according to the time schedule included in the plan,
which shall to the extent feasible provide reclamation simultaneous
with mining operations and in any event, initiation of reclamation
at the earliest practicable time after completion or termination of
mining on any segment of the permit area and shall be completed
within two years after completion or termination of mining.
RECLAMATION CONDITIONS
1. Provided further, and subject to the Reclamation Schedule, the
planned reclamation for the 1982-1992 permit period shall be: 1)
backfill the mine excavations to original elevation or higher
except as required for approved wetlands mitigation projects, the
final elevations may be below original surface elevations; 2)
stabilize waste disposal areas and settling ponds; and 3)
revegetate all affected lands.
2. The specifications for surface gradient restoration to a surface
suitable for the planned future use are as follows:

• Page 8 of 11
A. Reclamation of mined Land and settling ponds will be
accomplished in two phases: 1) physical restoration, and 2)
revegetation. Physical restoration will be accomplished by 1)
backfilling with dredged and/or SWE overburden, 2) backfilling
with sand tailings from the flotation section of the mill, 3)
clay disposal (from the mill) either as a topsoil conditioner
or in impoundments, and 4) backfilling with a blend of sand
tailings and/or gypsum, and mill clays.
B. When an area has been filled by dredge and/or BWE overburden
or sand tailings, dozers, pans and scrapers shall be used to
shape the area to the desired contour.
C. The blend of sand tailings and/or gypsum and clay tailings
shall be hydraulically transported to diked areas and
discharged. Some of these areas will be at existing ground
elevation and some will be diked up to elevations in
accordance with any dam safety permit issued by the
Department. The surface gradient of the blend shall initially
be determined by its slope at discharge. After drying, the
material shall be contoured with conventional mining
equipment.
D. The goals of rehabilitating clay settling ponds at or
associated with the Phosphate Operations are: 1) consolidate
the clays to gain additional clay storage, and 2) once
completely filled, comnit these settling ponds as wildlife
habitats (i.e. fresh water wetlands) or through research
determine their suitability as agricultural or forestry sites.
E. By July 1, 1988 and every six months thereafter Texasgulf
Inc. shall submit to the Department detailed reports of
reclamation activities and reclamation research for each of
the following:
1). Charles Tract clay waste areas
2). Clay -Gypsum blend areas
3). Gypsum areas
4). Tailings areas
5). other areas
Each report shall include a specific plan and schedule for
future reclamation and reclamation research.
3. Revegetation Plan
A. The revegetation plan is concerned with vegetating four basic
soil types:
1. Native topsoil.

' Page 9 of 11
2. Dredged overburden mixed with clay slurry to raise the
clay content to between 5--10% by weight in the 12-24
inches of the soil profile.
3. Sand tailings mixed with clay slurry to raise the clay
content to between 5-10% by weight in the top 12-24
inches of the soil profile.
4. A blend of sand tailings and/or gypsum --clay.
B. once an area is ready for vegetating, the overall plan for
each soil type is similar. Lime and fertilizers shall be
applied as recommended by the soil test results.

RE: Mine Utility Corridor Revision - 700-acre Expansion
Lee Creek Mine
Mining Permit No. 7-01
Beaufort County
Dear Mr. Furness:
This letter is in response to your letter to me dated July 17,
1992 and to confirm, in writing, the approval I granted to you
during our July 17, 1992 telephone conversation regarding the above
matter.
Your request has been approved to place a 30-inch culvert in
each of the uncut lead ditches and for the subsequent placement of
coarse granular washer reject material over said culverts to allow
equipment access to the mine utility corridor area along the
perimeter of the 700-acre mine expansion. The fact that the lead
ditches are heavily vegetated, existing rock check dams are located
at the end of each lead ditch (before they combine to form the
headwaters of Whitehurst Creek), and you will place and maintain
silt fence at the toe of the reject material at each culvert
location, this office feels that this procedure will fulfill your
requirements to allow water to continue to flow to Whitehurst Creek
without causing sedimentation.
For your information, the Land Quality Section has received
and is currently reviewing your renewal and modification request
for this site. However, to date, this office has not received a
formal letter and major modification fee to address the changes
made in the 700-acre expansion plan as a result of the recently
issued 401 Water Quality Certification, Please forward these
documents as soon as possible to Mr. Tracy Davis so they can be
incorporated in your renewal and modification package.

RE: Modification Request - Development Plan for the Mine Utility Corridor
around the 700-acre Modification Area
Lee Creek Mine
Mining Permit No. 7-01
Beaufort County
Dear Mr. Schimming:
This office has completed its review of your request to modify the above
referenced mining permit to allow the development of the mine utility
corridor around the 700-acre modification area. This is proposed to be
accomplished by leaving four (4) gaps in the perimeter canal system to permit
water to continue to flow through the existing lead ditches into the
headwaters of Whitehurst Creek.
As the Division of Environmental Management has recently issued a 401
Water Quality Certification for the 700-acre modification area, your request
is hereby approved, as indicated in your letter to me dated May 12, 1992 and
corresponding Pre Mining Development To Meet Mining Schedule plan dated May
7, 1992, including approval to construct the entire utility corridor without
the proposed gaps, provided that the following stipulations are met:
1.) all conditions and requirements specified in the 401 Water Quality
Certification (No. 2748) issued June 30, 1992 by the Division of
Environmental Management shall be followed.
2.) adequate erosion and sedimentation control measures shall be
installed and maintained downstream of any land disturbing activity
related to the construction of the mine utility corridor, most
specifically in those areas where water may flow directly into the
headwaters of Whitehurst Creek.

RE: Modification of Operating Condition No. 7.B.4.
Lee Creek Mine
Mining Permit No. 7-01
Beaufort County
Dear Mr. Schimming:
Charles H. Gardner
Director
The review has been completed on your modification request dated
October 12, 1990 to remove the last sentence of Operating Condition No.
7.B.4r which requires your company to develop and submit a plan by 1992
to blend all new clays and gypsum directly at the plants for permanent
waste disposal/reclamation.
As this office concurs that your company's current program of using
a three pile gypsum stack rotation is working successfully and is the
best technique for continued operation into the future, I hereby approve
your request provided that no new gypsum stacks are constructed.
Attached is a copy of this revised page 6 of Mining Permit No. 7-01
which contains the modified Operating Condition No. 7.B.4. Please
replace the existing page 6 of your permit with this modified page 6 for
future reference.
In regards to your company's intentions to place a cap of
approximately one to three feet of a 4/sand to 1/clay mixture on the top
of the R--2 Blend Pond for reclamation, please be advised that you must
file a justification for such activity and receive this office's
approval prior to capping R-2 with the sand/clay mixture. As you may
recall, Dr. Woodhouse had some reservations about this idea, as do I. I
recommend that only a section of R-2 be capped as a test, rather than
the entire pond, and request that you contact me directly when this
experiment takes place.

2. The remaining overburden shall be removed by draglines
and cast into previously mined areas in windrows.
B. Processing Waste:
1. Rejects: Oversized phosphate pebbles and gangue
materials in the ore matrix may be stockpiled in the
vicinity of the mill area. This material is used by
Texasgulf for internal road construction and maintenance,
and may be made available to State and local governmental
bodies.
2. Sand tailings: The quartz sand from the ore matrix shall
be pumped to mined areas (R1--R3) for backfill either
alone or in a blend with gypsum and clay, or for other
permitted uses such as blend dike construction.

Page 6 of 11
3. Clay: The clay material frcan the ore matrix shall be
pumped to the mined areas (R1-R3) for backfill either
alone or in a blend with gypsum. Clay --only discharges
shall not exceed 25% of the total time of any waste
discharges into previously mined areas (RI-R3). Records
documenting the amount of clay vs clay/gypsum blend
discharges into mined areas (RI-R3) shall be maintained
at the mine office and be avails -able for review by
Department personnel upon request.
4. Gypsum: During 1982-1991 a portion of the backfilled
mine excavation area will continue to be used to
stockpile gypsum (G-3,4,5; G-1; G-2; G-6). By 1992 a
plan to blend all new clays and gypsum directly at the
plants for permanent waste disposal/reclamation shall be
submitted to the Department for review.
8. Annual Reclamation Report
An Annual Reclamation Report shall be submitted on a form
supplied by the Department by February 1 of each year until
reclamation is completed and approved.

APPROVED RECLAMATION PLAN
The Mining Permit incorporates this Reclamation Plan, the performance of
which is a condition on the continuing validity of that Mining Permit.
Additionally, the Reclamation Plan is a separable obligation of the
permittee, which continues beyond the term of the Mining Permit.
The approved plan provides:
Minimum Standards As Provided By G. S. 74-53
1. The final slopes in all excavations in soil, sand, gravel and other
unconsolidated materials shall be at such an angle as to minimize
the possibility of slides and be consistent with the future use of
the land.
2. Provisions for safety to persons and to adjoining property must be
provided in all excavations.
3. All overburden and spoil shall be left in a configuration which is
in accordance with accepted conservation practices and which is
suitable for the proposed subsequent use of the land.
4. No small pools of water shall be allowed to collect or remain on
the mined area that are, or are likely to become noxious, odious or
foul.
5. The revegetation plan shall conform to accepted and recommended
agronomic and reforestation practices as established by the N.C.
Agricultural Experiment Station and the N.C. Forest Service.
5. Pern-Littee shall conduct reclamation activities pursuant to the
Reclamation Plan herein incorporated. These activities shall be
conducted according to the time schedule included in the plan,
which shall to the extent feasible provide reclamation simultaneous
with mining operations and in any event, initiation of reclamation
at the earliest practicable time after completion or termination of
mining on any segment of the permit area and shall be completed
within two years after completion or termination of mining.
RECLAMATION CONDITIONS
1. Provided further, and subject to the Reclamation Schedule, the
planned reclamation for the 1982--1.992 permit period shall be: 1)
backfill the mine excavations to original elevation or higher
except as required for approved wetlands mitigation projects, the
final elevations may be below original surface elevations; 2)
stabilize waste disposal areas and settling ponds; and 3)
revegetate all affected lands.
2. The specifications for surface gradient restoration to a surface
suitable for the planned future use are as follows:

Page 8 of 11
A. Reclamation of mined land and settling ponds will be
accomplished in two phases: 1) physical restoration, and 2)
revegetation. Physical restoration will be acccuplished by 1)
backfilling with dredged and/or BWE overburden, 2) backfilling
with sand tailings from the flotation section of the mill, 3)
clay disposal (from the mill) either as a topsoil conditioner
or in impoundments, and 4) backfilling with a blend of sand
tailings and/or gypsum, and mill clays.
B. When an area has been filled by dredge and/or BWE overburden
or sand tailings, dozers, pans and scrapers shall be used to
shape the area to the desired contour.
C. The blend of sand tailings and/or gypsum and clay tailings
shall be hydraulically transported to diked areas and
discharged. Some of these areas will be at existing ground
elevation and some will be diked up to elevations in
accordance with any dam safety permit issued by the
Department. The surface gradient of the blend shall initially
be determined by its slope at discharge. After drying, the
material shall be contoured with conventional mining
equipment.
D. The goals of rehabilitating clay settling ponds at or
associated with the Phosphate Operations are: 1) consolidate
the clays to gain additional clay storage, and 2) once
completely filled, commit these settling ponds as wildlife
habitats (i.e. fresh water wetlands) or through research
determine their suitability as agricultural or forestry sites.
E. By July 1, 1988 and every six months thereafter Texasgulf
Inc. shall submit to the Department detailed reports of
reclamation activities and reclamation research for each of
the following:
1). Charles Tract clay waste areas
2) . Clay --Gypsum blend areas
3). Gypsum areas
4) . Tailings areas
5). Other areas
Each report shall include a specific plan and schedule for
future reclamation and reclamation research.
3. Revegetation Plan
A. The revegetation plan is concerned with vegetating four basic
soil types:
1. Native topsoil.

Page 9 of 11
2. Dredged overburden mixed with clay slurry to raise the
clay content to between 5--10% by weight in the 12-24
inches of the soil profile.
3. Sand tailings mixed with clay slurry to raise the clay
content to between 5--10% by weight in the top 12-24
inches of the soil profile.
4. A blend of sand tailings and/or gypsum -clay.
B. Once an area is ready for vegetating, the overall plan for
each soil type is similar. Lime and fertilizers shall be
applied as recoitmended by the soil test results.
Seeding recommendations are as follows:
1. Dike slope 2:1 or 3:1 - Fall Seeding

During our meeting on November 5, 1992, you said that in order
to complete the review of our request to modify Mine Permit 7-1
to include the old Whitehurst Creek channel, you needed a
specific plan for reclaiming the channel. Enclosed is a 2-page
narrative describing the restoration of the Whitehurst channel
along with milestone dates, and two figures (reference map and
cross section) that visually depict the plan.
We would appreciate your early review and approval of this plan
along with the modification request. If you have any further
questions, please call Jeff Furness or myself.

Whitehurst Drainage Channel Restoration Plan
The following information is provided as an estimated schedule
of events that establish the restoration of the Whitehurst
drainage channel after mining.
Outline of RestorationSeguenc
I. Mining intercepts the fork of Whitehurst drainage
channel.
Date: December 1993 (this initiates the four year time
for completing drainage channel restoration).
II. Prestripping Operation places overburden backfill in
area of drainage channel after area is mined through.
Date: January 1994 to October 1994.
III. Restoration of main drainage channel construction is
completed in overburden backfill area.
Date: June 1994 to May 1995.
IV. Mining is completed in 700 Acre Mine Block.
Date: February 1995.
V. Sand tailing backfill in prongs of drainage channel.
Date: April 1997 to July 1997.
VI. Restoration of prongs and tie-in to main drainage
channel.
Date: July 1997 to October 1997.
Restoration Procedure
The restoration of the Whitehurst drainage channel will begin
by backfilling the area of the main channel with overburden
from the prestrip operation to near original grade (see area
indicted on attached map as BWE backfill). The backfill will
consist of sands, silts, and clays removed from the initial 35
feet of the overburden in advance of the dragline mining
operation.

After backfilling is completed, the area will be graded and
the location of the main channel will be excavated to
approximately the existing location and elevation. The
channel will be constructed to 3:1 side slopes and will be
established with a ten -foot wide bottom. Best management
practices outlined in the Erosion and Sediment Control
Planning and Design Manual will be used to prevent off -site
run-off. Vegetation will be established along the drainage
channel in a similar manner as was done in the existing
mitigation canal. This phase will begin in June 1994 and be
completed in May 1995.
After mining has been completed in the 700 Acre Block in
February 1995, the restoration of the two prongs of the
drainage channel with sand tailing will begin. Sand tailings
will be used for backfill of the two prongs. The sand tails
will be hydraulically pumped into the area west of the fork
(see area designated on attached map as Sand Tails Backfill).
The placement of the sand tailings will be completed in July
1997.
After sand tailings backfill is complete, the channel
excavation will be constructed in the approximate original
location and elevation of the existing channel. The channel
side slopes will be 3:1 and will be vegetated similarly to the
main channel and existing mitigation canal. Prong channel
restoration and tie-in to the main channel will be complete by
October 1997.
Blend placement in the R-5 Area adjacent to the drainage
channel restoration area will begin in April 1997 and be
complete in November of 1998. The area will be brought to
approximate existing grade and then revegetated. The attached
cross-section indicates the location of the channel and
backfill material at depth.
A survey of the existing main drainage channel and associated
prongs was completed prior to any mining activity and has been
cross -sectioned every 100 feet. The drainage channel survey
data is on file for future reference as a guideline.

Mine Permit 7-1
Mine Planning Department
November 5, 1992

Ten Year Mine Advance
Mining at the Aurora Phosphate Mine during the next ten years,
1993-2002, will continue the use of bucket wheel excavators
for overburden stripping in conjunction with draglines for
additional overburden removal and ore extraction.
Current mining operations include the use of two bucket wheel
excavators utilizing 12, one cubic yard buckets each, for
removal of the initial 35 to 40 feet of overburden. The 72
cubic yard, 68 cubic yard and 50 cubic yard draglines are used
for overburden removal and ore extraction. Two smaller five
cubic yard draglines are used to remove and clean rock from
the ore slurry sump.
The mine production estimate for ore matrix in 1992 is
13,141,000 tons. From this the following tonnages for sand
tailings, rejects, and clay can be calculated.
Product Percent Tons
Sand tailings 31.48
Rejects 3.75
Clay 19.05
4,1371000
493,000
2,503,000
Disposal of by-products from phosphoric acid production
(gypsum) and milling of the ore (clays) is accomplished by
"blending" these two by-products into a suitable mixture for
reclamation. The thickened clays are flocculated, mixed with
phosphogypsum, and pumped to reclamation areas as a slurry for
backfilling and capping mined -over areas.
Utilization of a gypsum/clay blend in the reclamation process
has occurred since 1986.
The placement of the blend will continue in future designated
reclaim areas R-3 through R-9 during the span of the ten year
mine advance.
The sand tailings will be utilized in the construction of
reclaim area embankments as well as utility corridors during
the next ten years of mining.
The reject material will be used primarily as road aggregate.
Future considerations for capturing the coarse phosphate
fraction of the rejects and tailings to enhance overall
recovery may be undertaken in the milling process during the
yea ten year period.
The attached Mine Data Table indicates the estimated volumes
and tonnages of the product/by-product material streams over
the ten year mine advance.
The attached Reclamation Data Table indicates disposition of
gypsum/clay blend, gypsum to the pile and sand tailings over
the ten year period.

Mine Permit 7-1
1993-2002
Answers to request for additional information in August 18,
1992 letter to Mr. W. A. Schimming, Manager, Environmental
Affairs, Texasgulf Inc. from Tracy Davis, Mining Specialist,
Land Quality Section, North Carolina Department of
Environment, Health and Natural Resources.
Answer to Question No. 1
Texasgulf has revised the table on Ten Year Renewal Report
Statistics to change the category of Reclaimed Areas to
Reclaimed Not Released (see Attachment 1).
Answer to Question No. 2
Reports responding to all the issues in question were provided
to Division of Environmental Management. A listing of these
reports appears on Attachment 2.
Answer to Question No. 3
The Texasgulf Groundwater Monitoring Network is divided into
four major areas of concern. The first area of groundwater
monitoring and most extensive is provided for under the
conditions of Capacity use Permit No. 3. Withdrawals for
adequate depressurization of the Castle Hayne Aquifer to
ensure safe, dry mining conditions are recorded at each well
covered under the permit. Samples for water quality as well
as water levels are collected routinely to record any changes
in the Castle Hayne Aquifer System in respect to
depressurization pumping. A network of monitor wells at the
mine and plantsite are checked weekly and monthly. The
monitoring plan also includes over 70 wells throughout
Beaufort County to measure more regional trends.
The second area of groundwater monitoring concerns the
Surficiai Aquifer System. A Capacity Use Permit Number 38-A2
provides for the withdrawals from the unconfined surficial
aquifer. Withdrawal rates, water quality and water level
recording are collected the same way as for Capacity Use
Permit No. 3.
PA

The third area of groundwater monitoring concerns the NPDES
Permit NC 0003255. Provisions for monitoring groundwater
quality near surge ponds, retention areas and the Recycle Lake
are covered under this permit.
The fourth area of groundwater monitoring concerns the
plantsite area. Special monitoring and remedial action
groundwater clean-up plans are active for the areas of the
acid cooling pond and tank farm. An attached list of reports
and plans concerning these areas of groundwater monitoring
have been provided on Attachment 2 for the Cooling Ponds and
Attachment 3 for the Tank Farm Area.
One of the attached maps of well location sites cover all
active monitor and withdrawal wells at the mine/plantsite as
well as one indicating the regional groundwater monitoring
network associated with Capacity Use Permit No. 3 (see
Attachment 4 and Attachment 5).
Answer to Question No. 4
Texasgulf intends to relocate a section of Highway 306 to the
east in order to accommodate the mine advance to the
northeast.
Answer to Question No. 5
The original Revegetation Plan in the Permit Renewal Package
was reviewed and approved by Mr. Gaylon Ambrose of the
Agricultural Extension Service on June 9, 1992. Based on past
experience, the seeding rates listed on the Revegetation Plan
are more than adequate for establishing a vegetative cover.
The dike areas are sand and do not erode, and the reclaimed
areas are flat and also do not erode. Therefore, seeding is
only done during optimum times of the year. Fescue is not
used on the reclaimed areas because it causes too much
competition for the tree seedlings that are planted.
N

Answer to Ouestion No. 6
Yearly projections for production over the Ten Year Permit
life are provided on the attached mine data table (Attachment
6). Values are expressed as tons and cubic yards for the
various material streams through the year 2002.
in addition, a reclamation data table is also attached that
summarizes the disposition and timing of the materials used in
the reclamation process (Attachment 7).
Also, an additional map indicating the mine advance by year is
provided as Attachment 8.
Answer to Ouestion No. 7
A listing of mining -related permits is provided on Attachment
9.
Answer to Ouestion No. 8
More detailed reclamation maps of the existing mine site and
Charles Tract are included as Attachment 10 and Attachment 11
showing estimated final contours. A cross section is also
depicted on Attachment 10 showing the area from Reclaim Area
No. 1 in the north, through Reclaim Area No. 5 in the south.
Each specific reclaim area is depicted on the maps with the
proposed areas of revegetation shown.
A mixture of various hardwood species will be planted in the
areas designated for tree planting on the maps. The low lying
areas designated as natural areas will consist of vegetation
that has emerged through natural succession which will be a
mixture of herbaceous aquatic plants.
Time specific information regarding revegetation is provided
semi-annually to the Division of Land Resources.

Response Addressing theNCPC Tract
Although Mine Permit 7-1 does not include any acreage on the NCPC
Tract, the current planned mine advance over the next ten years
takes in much of the NCPC area. An Environmental impact Statement
which includes the NCPC Area is approaching completion. After the
EIS process is finalized, the existing Mine Permit 7-5 which covers
much of the NCPC Tract can be merged with Permit 7-1.
