The Subject application has been reviewed for water
quality impacts and the following comments are offered:
1. The project will require a 401 Certification but
does meet the requirements for general
certification No. 1273 for effluent discharges
from upland diked disposal areas.
2. The transfer pipeline will require approval from
this Division in the form of an Authorization to
Construct under the current NPDES permit. Such
authorization will be based on submission and
review of detailed plans and specifications for
the transfer facilities since they are part of the
Company's wastewater collection and treatment

8. -Project summary The applicant is proposing to place a 30" clay transport pipeline
underneath South Creek from Sandy Landing to the existing clay pond system.
Environmental setting
A part of Texasgulf's phosphate
clay material from the mill to
South Creek. The transporting
pipeline underneath South Creek
in this pipeline was discovered
inoperable. This pipeline went
Project proposal
operations in Beaufort County is the transportation of
the existing clay disposal ponds on the south side of
of these materials has been through a 30" sub-aqueous
since the mid 1960's. On 16 February 1986 a rupture
which resulted in the transporting system being
from the existing pumping station to clay pond no. 1.
The applicant is proposing to abandon the ruptured pipeline and replace it with a new
30" pipeline. This new pipeline will be a sub-aqueous line and will extend underneath
South Creek from the existing pumping station to clay pond no. 5, a distance of
+ 3,570 feet. The proposed pipeline will be placed + 100' downstream of an existing
T8" sandtailings pipe which exists underneath South Creek.
The company reviewed several alternatives in regards to the type of pipe to be used
and in regards to construction methods.
The chosen pipe alternative consists of a 26 inch polyethylene pipe inside of a 30 inch
steel casing. The pipeline will be buried the entire length of the crossing. It is
felt that heavy ballasting of the pipeline will result in its sinking, except at the
east and west banks of the creek where the bottom consists of hard sand. At these
locations excavation will be needed. On the west bank a trench will be excavated 1000'
in length by 14' in width and to a depth of -8' at normal water level. On the east
bank a trench will be excavated 400' in length, by 14' in width and also to a depth of
-8' at normal water level. This excavation will be conducted either by a dragline
on a barge or by a hydraulic dredge.
Also proposed is the pressure testing of the pipeline prior to its use and a monitoring
system will be implemented to signal a failure in the pipe system.
Environmental impact
The project as proposed should have a minimal environmental impact. Impacts will
occur if the new line becomes ruptured resulting in a clay spill into South Creek.

Dear Mr. Gossett:
As you know, on February 16, 1986, Texasgulf had a
failure in the sub-aqueous pipeline used to transport clay
material from the Mill area to the clay disposal pond
system located near the confluence of South and Bond Creeks.
Since that time, a number of options have been evaluated
which would allow continued pumping of clays to the disposal
area. These options have included repairs to the existing
pipe, lining the existing pipe, use of an existing 18" line,
or installation of a new line.
After careful consideration, the installation of a new
30" lined pipe has been determined to provide maximum long
range protection to the environment while having minimum
impact during installation. Our evaluations have been
carefully reviewed by Henry Von Oesen and Associates of
Wilmington and they agree with our evaluations. Attached
is a letter from Paul Denison of Von Oesen providing this
concurrence.
The proposed line will extend from the existing pumping
facility (Sandy Landing) parallel to the existing sand
tailings line to the No. 5 Clay Pond area. Some excavation
in the shallow water near each shore will be necessary to
allow the pipe to be placed below the creek bottom. The
method of excavation will be determined by the contractor,
but the method will be restricted to a dredge or a barge
mounted clamshell or similar equipment. If a dredge is used,
the spoils will be placed in the existing clay pond system.
If•a clamshell is used, we plan to place the spoil adjacent to
the cut for return after the pipe is in place.
(ATg Mr. vossett - 2 - June 10, 1986
As indicated in Mr. DenisonIs letter and the geotechnical
report by Soils and Material Engineers, Inc. (page 5), the
pipeline is expected to immediately settle several feet into
the bottom silts once the pipeline is away from the narrow
strip of firm bottom at each shoreline. The pipe will also be
weighted to promote additional settling.
If you have any further questions about this application,
please contact me.

Re: South Creek Pipeline Replacement
Dear Mr. Thomas:
In accordance with your recent request and our numerous
meetings and discussions on the subject, this is to advise of
our recommendations concerning replacement of the Texasgulf
Chemicals Co. subaqueous pipeline across South Creek adjacent
to your plant. The recommendations herein are also consistent
with our discussions and presentation to representatives of the
North Carolina Department of Natural Resources and Community
Development in Washington, North Carolina on 28 May 1986.
After analysis of numerous options, we have selected the
alternative of encasing a high density, thick wall, 26-inch
polyethylene pipe inside of a 30-inch steel casing
with burial of the pipeline in the river bottom for the entire
length of the crossing. Analysis of numerous options, including
deep trench dredging, shallow trench dredging with bent supports
for the pipeline and even an elevated pipeline crossing led us
to the conclusion that heavy ballasting and simple sinking of
the casement pipe would be the preferred option.
We feel that this is possible based on the results of test borings
performed by Soil & Material Engineers, which indicates that the
overburden bottom materials (above hard or dense sand) was comprised
of extremely soft unconsolidated silty type materials which would
-allow the ballasted pipeline to sink through these materials to
approach the hard bottom. Technical design details relative to
this proposed method of installation will. be included in our
project design package which will be furnished to you within a
few days.-
We feel that this selected option provides the best technical
solution to the problem and is also by far the least environmentally
disturbing of the numerous options considere oo In this case only
a small amount of materials (approximately cubic yards) would
have to be dredged from the shorelines to insure sufficient burial
of the pipeline on the hard bottom in these areas. There would
be a minimum of three to four feet of cover on the pipe sections
at the shore approaches, with increasing coverage of the buried
Mr. Robert M. Thomas

pipeline in the natural bottom materials up to depths of 17 to
18 feet near the center of the crossing. Comparatively speaking,
we estimate that approximately 180,000 to 200,000 cubic yards
of material would have to be dredged from the river bottom to
allow open trench burial of the pipeline. Similarly, 40,000 to
50,000 cubic yards of material would have to be dredged from a
shallow trench. to allow installation of the bent-supported pipeline
system mentioned above.
Finally, we propose to insure the integrity of both the
inside and outside (casing) pipes by pressure testing prior to
commencement of operations. Additionally, a monitoring system
will be installed on the casing pipe which will immediately detect
and signal any failure of the materials pipe by allowing any materials
that escape into the encasing pipe to overflow into a sump and/or
tailings pit where they will be detected during any of the numerous
daily inspections of the materials pumping station at the river's
edge. Arrangements will also be made periodically-to pressure
test the encasing pipe to constantly insure its integrity.
I hope this information is satisfactory to your immediate
needs. We look forward to meeting with you again in the very
near future to review final technical details of the proposed
project. Please call if you have any questions or if we may
assist further in any way.
Sincerely yours,
