Contact Information: James Pinkney, (404) 562-9183, pinkney.james@epa.gov
(ATLANTA - Oct. 24, 2011) The U.S. Environmental Protection Agency (EPA) announced today that
work is scheduled to start in early November 2011 on a cover system (a thin layer sand cap
over dioxin contaminated
sediment) in.a portion of Welch Creek at the Weyerhaeuser Superfund Alternative site in
Plymouth, NC. i
The current owner, Domtar Corporation, will perform the work with oversight by EPA and the
North Carolina Department of Environment and Natural Resources (NCDENR). EPA selected the
remedy after consultation with other federal and state agencies and consideration of public
comments. The work is expected to be completed by March 2012.
The purpose of the sand cap is to reduce the uptake of contaminants by fish and other aquatic
organisms. The sand cap along with natural recovery is expected to contribute to the
eventual lifting of the current fish consumption advisory for catfish and carp in Welch
Creek.
The sand cap will be installed on about one,mile of the creek bottom beginning just
downstream of the railroad trestle over the Creek.
The sand will be distributed from a barge operating in the creek. The sand will be installed
in several passes and will be approximately 2-4 inches thick. The barge will move along
cables installed across the creek in the work area. The cables will be marked with buoys
and/or lights and the cables will be removed once construction is complete.
Although access to Welch Creek is already somewhat limited from the Roanoke River, boaters
should expect to find silt curtains and heavy equipment prohibiting further access downstream
of the railroad trestle or upstream of the Main Street Bridge during the construction.
t
During construction, water quality will be monitored with turbidity meters and the chemical
testing of surface water samples. The pace of the work may be modified based upon the
monitoring results. In addition, there will be long term monitoring of the cap and
conditions in Welch Creek as part of the remedy.
The 2,400-acre Weyerhaeuser Company Plymouth Wood Treating Plant site is an active wood pulp
mill located near the confluence of Welch Creek and the Roanoke River in Plymouth, Martin
County, North Carolina. The site began operations under the Kieckhefer-Eddy Company in 1937,
was owned and operated by the Weyerhaeuser Company from 1957 until 2007, and is currently
owned and operated by Domtar Corporation.
The site is not listed on the National Priorities List (NPL), but is considered to be an NPL-
caliber site and is being addressed through the Superfund Alternative Approach. This approach
uses the same investigation and cleanup process and standards that are used for sites listed
on the NPL.

Kari,
Based on limited information about your mitigation efforts, I can only tell you to continue by Tier Two response
guidelines, meaning that monthly monitoring shall continue until three consecutive sample results are bellow the
benchmark values. If no discharge occurs during the sampling period, the permitee is required to submit a monthly
monitoring report indicating "No Flow".
Thanks

Hi Samir.
We have been monitoring three outfalls that are tier II status. We have been trying to collect samples
from two of the three outfalls during rain events for the last three months and have not had flow due
to the mitigation efforts in place. At what point will these outfalls no longer be classified as tier II if we
can't collect a sample?

Good Morning Samir,
This email is in follow up to the phone
conversation I had with Al earlier this
morning. As discussed, we have
observed stormwater overflowing the
bulkhead on the north side of our facility.
We were notified of this overflow
occurring at about 4:50 this morning. This
overflow is resulting from the heavy rains
we are currently experiencing. As of 8:30
this morning, we have recorded
approximately 11 inches since this rain
event began on 9/26. In anticipation of
overflowing the bulkhead, we collected
samples from the area yesterday and will
conduct analyses on them.
This stormwater runoff is from the back
side of our mill site and under normal
conditions, this stormwater is pumped to
our wastewater treatment system.
However, the pumping station cannot
handle the volume of rain we are currently
experiencing. As a result, the runoff has
collected along the bulkhead and is
overflowing along the entire length of it.
The bulkhead is approximately 200 yards
in length. We are unable to estimate the
quantity of overflow. As the rain
continues, it is possible that the river will
start overflowing onto our side of the
bulkhead as well.
Please let me know if you require any
additional information concerning this
notice. Thank you.

Re: Request to Remove Dioxin Sampling/Analysis Requirements from permit and Request for
Representative Outfall Status for Domtar Paper Company, LLC — Plymouth, North Carolina, NPDES
Stormwater Permit #NCS000189
Case Background
• July 24, 2009
DWQ issued a NPDES Stormwater Renewal permit # NCS000189 to
Domtar Paper Company, LLC located in Plymouth, Martin County,
North Carolina.
• March 9, 2010
Request for removal of Dioxin Sampling/Analyses requirement from
the NPDES permit, as well as Request for Representative Outfall
Status for two areas of the facility and removal of the requirement to
sample outfall due to sheet flow conditions.
• March 31, 2010
On March 31, 2010, Samir Dumper of the Washington Regional
Office conducted a facility inspection, together with Diane Hardison,
Tamika Boone and Alan Barnes of Domtar Paper Company, to
determine if request for removal of Dioxin Sampling/Analysis and
representative Outfall Status can be granted.
• August 11, 2010
The additional sampling for two complete monitoring periods
submitted, as well as soil sampling at the areas likely to be affected by
dioxin as requested.
Facility Inspection findings
Request to Remove Dioxin Sampling/Analysis Requirements from Permit.
At the time of Request to remove Dioxin Sampling, only one analytical sampling (for first six-month
monitoring period) was performed. Dioxin analyses results for the sampled outfalls were all bellow
detection levels, however we in the WaRO requested additional sampling (for second six-month
monitoring period) to be performed and evaluated for dioxin, as well as soil sampling at the location
where the dioxin could potentially be introduced to site due to flooding of Welch Creek. On August 11,
2010 the WaRO received completed second sampling results as well as soil samples at 4 locations. All of

the stormwater outfalls samples came back with no dioxin detected, while one of the soil samples taken at
Winter Log Storage area came back with positive results. The positive dioxin level was extremely small
(0.704 ng/kg) and well below the method reporting limit but above the estimated detection limit
The WaRO recommends partial approval of the request for dioxin sampling removal from the NPDES
stormwater permit NCS000189. We believe that the dioxin sampling should be continued only at the
Winter Log Storage area.
Request for Representative Outfall Status for Outfall CL14.
Outfalls CL1 I, CL13 and CL14 are closely located to each other and service the Contractor Laydown
Area. This area of the facility does not have any raw materials or processes placed on it, hence the
biggest concern as far is analytical monitoring is TSS and pH. The drainage areas for outfalls CL13 and
CL14 is approximately same with the drainage area for outfall CL1 I being slightly larger. On my
recommendation, Ms Diane R. Hardison, the Environmental Manager of the Domtar Paper Company
agreed to have outfall CL11 as Representative Outfall instead of CL14 as requested.
At this time the WaRO believes that granting the Representative Outfall Status for Outfall CL11 would
not diminish the quality of data for these three areas, hence we recommend approval of the
Representative Outfall Status for Outfall CL11.
• Request for Representative Outfall Status for Outfall LF01.
Outfalls LFO1 and LF02discharge stormwater from two sedimentation ponds which collect runoff from
the closed, capped and vegetated No. 2 Landfill. Site visit confirmed that LFO1 on the east side of
Landfill No. 2 regularly discharges flow during moderate to heavy rain events, while the outfall LF02
located on west side of Landfill No. 2 rarely discharges Flow. Only excessive rain events of this winter
and spring caused discharge from LF02.
The WaRO concludes that granting the Representative Outfall Status to outfall LFO1 would be beneficial
to both parties, DWQ and Domtar Paper Company.
• Request to remove the requirement to sample outfall WRA from the permit due to sheet flow.
Conditions was retracted by the Domtar Staff due to facility inspection. Domtar collected samples
from this outfall during rain event in March of 2010.

SUBJECT: Proposed Site Remediation at Welch Creek, Martin County, North Carolina (DCM#20100026)
Dear Mr. Sylvestre:
In June the US Environmental Protection Agency (EPA) requested that Domtar initiate and complete
remediation work at Welch Creek. Your response (June 22, 2010) to the EPA included a solicitation that the
State of North Carolina reconsider its previous decision. Domtar requested an extension of time from
March 2, 2011 to April 1,.2011 for allowing in -water work.
This extension request by Domtar was forwarded by the North Carolina Division of Coastal Management
(DCM) to other State agencies that would have a regulatory interest. After careful coordination with these State
Agencies, DCM upholds our previous concurrence that in -water work will only be permissible from
October 1, 2010 to March 2, 2011: In that concurrence we also requested that remediation work be completed, if
possible, by February 15th to meet the offer of an earlier request by Domtar to have 137 working days available
for completing the remediation work.
Should you have any additional comments or questions, please contact me. Thank -you for your consideration of
North Carolina's Coastal Management Program.

Coal Pile Runoff
PROJECT DESCRIPTION
The drainage system in the coal yard will be modified to divert all
stormwater runoff away from Welch Creek. Currently, most of the rainfall
that enters the coal yard is directed to an existing stormwater pumping
station and pumped to the waste treatment system. Topography at the
southeast corner of the yard, however, allows some runoff to enter nearby
roadside ditches, which eventually flow into the creek. Existing earth
ditches within the coal yard are hard to maintain and frequently fill up with
silt and debris. Many of the culvert pipes associated with the earth ditches
are filled with dirt due to the flat slopes in the area.
Modifications to the existing drainage system include the following:
• Install new concrete -paved swale on the west side of the coal yard,
between the north -south roadway and conveyors, to collect and divert
runoff away from the conveyors
• Install new storm drain culverts and concrete -lined ditches to replace
ineffective earth ditch systems throughout the coal yard
• Install new culverts to replace existing damaged CMPs
• Regrade the southeast corner of the coal yard to prevent runoff from
leaving the site
CONSTRUCTION SCHEDULE
Construction can be executed while the mill is in operation. Once the
project is awarded, it is anticipated that the construction duration, from
award to project -turnover, will be twelve to fourteen weeks.
FLOW RATES
There are currently no wet processes within the coal yard, so average flow
rates in the coal yard are non-existent. The peak flow associated with the
25-year design storm is 16 CFS.
Woodyard Drainage Improvements
PROJECT DESCRIPTION
The purpose of this project is to divert stormwater runoff from outfall #008
to the Woodyard Ditch and to improve drainage on the west and north ends
of the woodyard. Four infrastructure modifications will be made to
accomplish this: 1) Install a new asphalt roadway to replace the existing
earth road (west side of chip piles), 2) Install new concrete -lined drainage
ditches parallel to the roadway that will flow into the Woodyard Ditch,
which flows to the waste treatment area, 3) Install new, raised, gravel
roadway north of the woodyard to allow maintenance vehicles to access the
fire pump house during periods of high water, and 4) Install new settling
sump and oil skimmer to collect runoff at the vehicle maintenance area.
Outfall 9008 will be eliminated as a result of these changes.
CONSTRUCTION SCHEDULE
Construction can be executed while the mill is in operation. Once the
project is awarded, it is anticipated that the construction duration, from
award to project -turnover, will be twenty-one weeks.
FLOW RATES
There are currently no wet processes within the woodyard, so average flow
rates in the woodyard are non-existent. The peak flow associated with the
25-year design storm is 17.7 CFS in the area to be modified.
Area 8 and Fine Paper Drainage Improvements
PROJECT DESCRIPTION
The purpose of this project is to eliminate stormwater runoff into the river
from the Area 8 and Fine Paper drainage area. Currently, two outfalls in the
region discharge into the Roanoke River. The outfall designations are 4005
and #007. A steel sheetpile wall will be installed along the riverfront. A
stormwater impoundment area will be constructed on the south side of the
wall. The impoundment will be sloped to drain to a new pumping station. A
simplex pump will be housed in the station and will be designed to
discharge to the Fine Paper Sewer. New yard inlets and underground storm
drains will be installed to reroute storm flows that currently drain to the
river. The new storm drains will be directed to the new pumping station.
CONSTRUCTION SCHEDULE
Construction can be executed while the mill is in operation. Once the
project is awarded, it is anticipated that the construction duration, from
award to project -turnover, will be thirty-four weeks. (12 weeks for
permitting + 22 weeks for construction). The 12-week permitting allowance
is for obtaining a dredge & fill permit for filling along the riverbank. It may
be possible for the contractor to start on other areas of the project, away
from the river, to shorten the duration of the project.
FLOW RATES
There are currently no wet processes within the area, so average flow rates
are non-existent. The peak flow associated with the 25-year design storm is
144 CFS. All stormwater runoff will be collected and impounded. The
simplex pumping station will slowly pump impounded flows to the Fine
Paper Sewer at a rate of 650 GPM.
No. 1 Lift Station Rebuild
PROJECT DESCRIPTION
The purpose of this project is to replace the existing No. 1 Lift Station with
a new lift station. The existing No. 1 lift station facility consists of a series
of earth (unlined) effluent ditches that discharge into an earth-and-sheetpile
basin. A platform with six vertical, mixed -flow pumps lift incoming flows
from the basin to the control pond in the waste treatment area.
Modifications to the existing facility include the following:
• Replace the existing unlined earth ditches with reinforced concrete pipes
• Install measuring devices (Parshall flumes) to measure each major
process sewer entering the system
• Install continuous monitors (pH & conductivity)
• Install a screening structure to screen out debris prior to entering the lift
station basin
• Replace the existing earth basin with a concrete -lined basin
• Install new sewer from the existing fiberline lift station basin to the new
No. 1 lift station basin. The new sewer shall be sized to accommodate
the existing fiberline, future de -inking facility and future fine paper
machine. The fiberline lift pumps are to be abandoned once the tie-in
sewer is installed and on-line.
• Install new tie-in for storm sewer from the main office parking lot and
future power and recovery process sewer.
• Replace the six mixed -flow pumps with new pumps designed to handle
the increased flow volumes
CONSTRUCTION SCHEDULE
Construction can be executed while the mill is in operation. Once the
project is awarded, it is anticipated that the construction duration, from
award to project -turnover, will be approximately thirty-nine weeks.

FLOW RATES
Current process flows entering the No. 1 lift station average 39 million
gallons per day (MGD). 9.3 Pulp Mill Sewer + 10.9 Paperboard Sewer +
10.8 Fine Paper Sewer + 8.0 Bleach Sewer. Current maximum flows into
the lift station equal approximately 46 MGD. 11.2 Pulp Mill Sewer + 12.8
Paperboard + 14 Fine Paper Sewer + 8 Bleach Sewer. The new pump
station will be designed to handle maximum flows of 112 MGD. 12 Pulp
Mill + 12 Future Power & Recovery Sewer + 13 Paperboard + 8 Bleach +
16 Fine Paper + 28 Future Gravity Fiberline + 4 Future De -inking Facility
+ 19 Future Main Office Lot QZS Storm Flows. (All flows listed in MGD).
Main Office Parking Lot Drainage
PROJECT DESCRIPTION
The purpose of this project is to eliminate stormwater runoff into the river
from the Main Office parking lot and surrounding areas. The existing
asphalt -paved parking lot, which is currently sloped to drain into the river,
will be demolished, re -graded and re -paved. A series of new catch basins,
along with a new gravity sewer that discharges into the No. 1 lift station will
be installed. (The new gravity sewer to the No. 1 Lift Station does not
appear on the site maps yet).
CONSTRUCTION SCHEDULE
Construction can be executed while the mill is in operation. A temporary.
parking area will need to be constructed during demolition and
construction. Once the project is awarded, it is anticipated that the
construction duration, from award to project -turnover, will be twenty-two
weeks.
FLOW RATES
There are currently no wet processes within the parking lot, so average flow
rates are non-existent. The peak flow associated with the 25-year design
storm is 29 CFS.
Pulp Mill Sewer Replacement
This project will repair or replace as necessary, the Pulp Mill Sewer (the
mill's oldest sewer). The sewer is a concrete box culvert with a solid cover.
The original concrete walls were not coated. Over the years, the walls have
deteriorated. Approximately 1/3 of the sewer has been lined with acid brick
and mortar and is believed to be in good shape. The remaining 2/3 of the
sewer has not been inspected in years. Its structural integrity is in question.
Options to repair the sewer include lining the remaining 2/3 of the sewer
with acid brick and mortar or slip -lining portions of the sewer and acid -
bricking other sections. Slip -lining the entire sewer is not possible due to its
configuration and the number of tie-ins required. A replacement sewer is
also being studied. The concept is to install a parallel sewer next to the
existing sewer. The new sewer would be constructed of corrosion -resistant
materials. When complete, the existing sewer would tie into the new sewer
and the old sewer would be abandoned. This option would involve re-
routing many underground and aboveground lines that tie into the existing
sewer.
Finally, a new Power and Recovery Sewer is being studied. The re -built No.
1 Lift Station will be installed deep enough to accommodate a new gravity
sewer from the power and recovery area. This sewer could replace the Pulp
Mill Sewer or supplement it.
CONSTRUCTION SCHEDULE
Depending on the chosen option, construction may or may not be able to
occur during normal mill operations. If the option of lining the existing
sewer is chosen, the project would more than likely be executed during
shutdowns. It is possible to isolate certain sections of the sewer during
normal operations, but this approach would be riskier in terms of safety.
The duration of such work would be dependent on the approach taken. If the
option of installing a new sewer is selected, the project duration could
extend beyond one year.
Pulp Mill Sewer Replacement

FLOW RATES
The current average daily flow rate in the Pulp Mill Sewer is 9.3 MGD.
Maximum flows equal 11.2 MGD.

Subject: RE: Question Concerning Stormwater Sample Result
Kari,
I am OK with using this sample instead of collecting another one. I will print out this e-mail and put it in Domtar file. We
don't run into this problem very often, but considering Domtar's good compliance and cooperation history and
considering that you are way bellow benchmark value, we will accept this sample.
Thanks
Samir

Subject: Question Concerning Stormwater Sample Result
Samir, when we ran our BOD on one of our stormwater samples it used up all of the DO except .12 mg/L. The procedure
says that you have to have at least 1.0 mg/L leftover or it's not a good sample. The BOD based on our sample was 8.26.
Since the benchmark is 100 and the result was 8.26, would it be alright to use this sample result or do you want us to
collect another sample and re -run it? Please advise. Thanks.
