NPDES Stormwater Permit NCG210000, Certificate of Coverage NCG210354
Montgomery County
Dear Mr. Aikmaw
Staff with the Fayetteville Regional Office of the Division of Energy, Mineral and Land Resources (DEMLR) has reviewed
your request received on September 21, 2018 for a determination that stormwater discharge outfall (SDO) 2 be granted
Representative Outfall Status for stormwater outfalls 1, 2 and 3. Based on the information provided on the request form
along with observations made during a compliance inspection conducted on June 11, 2018, we are approving this
request. In accordance with 40 CFR §122.21(g)(7), you are authorized to sample SDO 2 as a representative outfall. This
approval is effective with the next sampling event. Please be reminded that the permit requires Qualitative (visual)
Monitoring to be performed at all stormwater discharge outfalls, regardless of representative outfall status.
Please remember that any actions you initiate in response to benchmark exceedances as directed in the tiered response
provisions of your permit must address all drainage areas represented by SDO 2, where appropriate.
Please append this letter to your Stormwater Pollution Prevention Plan (SPPP) to document that representative outfall
status has been approved. If changes in drainage areas, structures, processes, storage practices, or other activities occur
that significantly alter the basis of this approval, representative outfall status is no longer valid. In that case, you should
resume sampling at all SDOs, or reapply to this office for representative outfall status based on updated information. If
you have any questions or concerns, please contact me at [phone] or via e-mail at mike. [e-mail].
Sincerely

Subject: [External] Storm event
Good morning Mike I hope you fared well from Florence. I tried calling you around 11 this morning to ask a couple
questions related to the storm event. Our cell system did ok but we did have an overflow at basin 3 due to the
storm. We are also having to discharge from the treatment cells to basin 2 and discharge basin 2 due to the amount of
water collected during the storm We received 10.6 inches of rain in a 48 hour period.
I am taking a sample of the discharge and will end it out for testing. The water is fairly clear, no noticeable solids, il in
the water.
Do we need to report the discharge?

Inspection Summary:
Reason for Visit: Routine
Met with Chris Robillard, Environmental Safety & Health Manager, Rebecca Bolden, Director of Environmental, Steve
Russell, Plant Manager, Ric Aikman, General Manager, and Dr. Bob Rubin with NCSU. Purpose of the inspection was to
determine compliance with the conditions of NPDES Stormwater General Permit NCG210000 and make observations of the
constructed wetlands system, which was installed by the facility in 2015 after a pilot wetlands study to address levels of
COD and TSS in their stormwater discharges that consistently exceeded the associated benchmark values. The
constructed wetlands system consists of two wetland cells, which receive stormwater that has been captured in basin 3 and
pumped into one of the cells as needed for retention and treatment. Each wetland cell has a skimmer device on a,hoist that
can be lowered to the water surface for release to basin 2, which also has a skimmer device on a hoist that is connected to
an outlet structure for subsequent discharge and sampling at outfall 2. Basin 1 located on the opposite side of the plant
receives little to no stormwater flow and rarely discharges. Based on the facility's monitoring data since completion of the
constructed wetlands, the levels of COD and TSS in their stormwater discharges have drastically decreased with the most
recent results at or below the benchmark values, Facility's Stormwater Pollution Prevention Plan (SPPP) contains all
permit -required components, however was last updated in 2014. The SPPP Amendment and Annual Update requirements
listed under Part II, Section A, item 8 of the NCG210000 permit were reviewed with facility staff. Also discussed was the
process for requesting Representative Outfall Status (ROS) and a copy of the ROS Request Form was e-mailed to facility
staff. Facility has done a tremendous job in their efforts to address the levels of potential pollutants in their stormwater
discharges. At the time of inspection, it was determined by the inspector that the facility is in substantial compliance with
the conditions of the NGG210000 permit.

Brad Cole:
r•r - m
Thank you and your colleagues for visiting with our Unilin team to discuss a path forward
on the storm water management effort at the Mt. Gilead facility. Your colleagues at the
North Carolina Department of Environment and Natural Resources (NCDENR)
Fayetteville Regional Office (FRO) have been very cooperative in seeking a mutually
beneficial storm water management program. Our intention is to develop a model
program which could be utilized by others in the forest products field to address storm
water issues. Our preliminary testing has been developed in cooperation with
representatives from the FRO. The testing followed from a series of discussions on
treatment wetlands with representatives from North Carolina State University (NCSU),
Waters Edge, and your office. The result of that discussion process was implementation
of the testing program which was initiated in 2012. Based on those results, the hybrid
wetland appears to be the industrial storm water treatment option of choice, but the
loading to the wetland cells, the management of the cells, and the testing pose some
limits on our decision process. To date, Unilin has invested over $65,000 on this
assessment and before we invest significant additional funds towards a full scale
implementation, we want to be confident that the option will function properly.
We wholeheartedly agree that the testing program should continue for additional time to
allow testing of our hybrid wetland on a slightly larger scale which would be more
representative of real life loading criteria. Our proposal involves:
1. Combining the three (3) existing wetland cells into a single hybrid wetland cell
2. Improving the dosing system to allow continuous or metered flow into the wetland
cell as necessary to mimic a full scale operation
3. Comprehensive performance assessment involving flaw monitoring and monthly
influent and effluent testing
4. Assessment of the outfall from effluent point 2
Path forward:
1. The three cells will be collapsed into a single cell combining both the surface
flow and subsurface flow wetland treatment processes. The combined cell
represents approximately 10% of the area proposed for the full scale
operation. This will allow diversion of 10% of the flow from outfall 3 to the test
cell. This will reduce pollutant load emanating from outfall 3; granted a 10%
reduction does not eliminate the discharge; however, it does represent a
pollutant discharge reduction. This phase will be completed by October 4cn
2013.
2. Liquid from the equalization pond will be pumped routinely to the test cell.
The test cells will be loaded routinely to mimic proposed full scale operation

and the liquid will remain in the cell for a minimum of 14 days prior to being
discharged. Once this steady state process is established, loading and
discharge will occur daily. Monitoring will be performed on a monthly basis.
The required changes to allow the new operation and testing method to
commence will be completed by October 31, 2013.
3. The monitoring will include daily assessment of flow discharged from
equalization cell to the test wetland. Monthly samples of the influent and
effluent will be assessed for COD and TSS as required in our storm water
permit. Additional process monitoring will be performed in the cell for DO, pH,
and TOC. This will be an ongoing task that will commence upon the
completion of task 2 above.
4. The liquid from the test cell will discharge into outfall 2; this outfall will be
assessed monthly for the parameters listed in the general permit. In addition,
DO samples will be collected from the polishing pond immediately up -
gradient from the outfall. This will commence upon the completion of task 2
above.
5. All monthly test results'for outfall #3 will be sent to Mike Lawyer in addition to
the required copy being submitted to central files per our permit.
Testing will continue until spring of 2015 when we will commence construction on the full
scale version of the wetlands. The target date for completion of the full scale treatment
wetlands is May of 2015. This comprehensive assessment will provide Unilin and the
State of North Carolina with vital additional information necessary to properly design and
optimize the future storm water management option for Unilin. This technology and data
may provide aid to similar forest products sites that are unable to comply with the lumber
and wood products regulations.

• Memo From: A. R. Rubin
Subject: Best Available Control Technology Economically
Achievable for Stormwater Treatment at Unilin
TO: Ric Aikman, Bob Pierce, Charles Wright, Phil Rahn
Stormwater controls are required to comply with provisions in Federal water quality
requirements and North Carolina Law. Policy allows technology evaluation based on both
technical feasibility and economic achievability. Challenges to treatment of the stormwater
runoff from the wood storage area must address elevated COD and high suspended solids. The
treatment technologies available to reduce these constituent concentrations to acceptable levels
include mechanical treatment systems and natural treatment systems. The technology selected to
address the industrial stormwater treatment at Unilin must be capable of operating under variable
flow regimens and capable of accommodating high strength industrial stormwater. Typically,
wastewater treatment technologies are developed to reduce constituent concentrations under
ipredictable flow regimens; specified wastewater volume and specified strength. This industrial
stormwater system generates flow only during storm events and constituent concentrations in the
runoff are dependent on the volume of wood chips stored on the site; low volume storage
generates high concentrations of TSS. Wastewater treatment technologies intended to remove
pollutants from water were typically not developed for stormwater. Consequently, selecting a
technology that is effective and economically sustainable is challenging. An options assessment
process is described below to define the best available technology economically sustainable to
manage the industrial stormwater generated at Unilin.
Some traditional wastewater treatment technologies such as ultrafiltration or reverse osmosis are
prohibitively expensive and would malfunction quickly due to high TSS in the liquid. Other
more traditional treatment technologies such as media filters, would fail quickly due to the high
concentration of suspended solids in the runoff. Pond systems, evaporation systems, mechanical
or aerobic systems, and advanced filtration technologies pose significant design challenges and
operational costs are high. These technologies and the constructed wetland option are described
below. Crites (2006) provides an excellent academic reference discussing the potential of natural
systems to remove BOD, COD, and TSS.

• For purposes of the comparison which follows, the industrial stormwater flow and quality
assumptions are:
FLOW
For purposes of this assessment assume the area generating the industrial stormwater measures
eight acres, that back-to-back storm events of four inches constitutes the design flow and the
liquid requiring treatment contains TSS and COD of 200 mg/l. The volume is calculated as:
Q: 8 Ac x 4 in x 2 events x 27,154 gal/ac-in = 1,737,850 gal
(say 2 MG/event or 40 MGY)
BOD: 2 MG x 200 mg/l BOD x 8.34 = 3,336 lb. BOD/design event
TSS: 2 MG x 200 mg/1 TSS x 8.34 = 3,336 lb. TSS/design event
For purposes of a design, assume an equalization pond is developed to accommodate the initial
stormwater volume and the flow is attenuated over 4 days. The daily flow into a system is then
calculated as:
Q: 1,737,850 gal/4 days = 435,000 GPD
BOD or TSS: 3,336 lb BOD/4 = 834 lb/d
• OPTIONS
Evaporation:
Natural evaporation systems will not function in NC because rainfall exceeds evaporation
creating a net precipitation excess. Communication from Unilin indicated an Evaporation system
had been considered for other functions in Mt. Gilead and were not pursued as a viable option
because of cost. An Evaporation system sufficiently large enough to handle a major rain event
would be expensive; in this previous discussion an evaporation system intended for a different
water source yet requiring a similar amount of piping and equipment the cost was estimated at
$5,000,000. Estimated cost for an evaporation system to accommodate the stormwater is over
$5M.
Treatment Pond
A pond system could be developed to accommodate the design event stormwater flow equalized
over the 4 days as described. Typically, ponds are developed to accommodate BOD loads of 60
to 80 lb/ac/day organic matter. The 834 pounds of organics generated in the design event would
• require a pond with area calculated as:
POND: 834 lb/80 lb/ac/d = 10.3 acres

• This area could be reduced by the addition of mechanical aeration to the pond system or by
developing an advanced integrated pond treatment system incorporating facultative and aerobic
components.
•
0
Traditional pond systems have been developed to accommodate industrial wastes containing
BOD values in excess of 1,000 mg/l. The industrial stormwater generated at Unilin is suited for
treatment in a pond system containing an estimated 10 acres provided the input is metered into
the system in controlled doses and the pond system is equipped with appropriate structures to
prevent short-circuiting.
Estimated costs associated with development and operation of a large pond system are:
Description Cost
Excavation 10 ac x 3 feet = 30 ac ft or 48,500 $ 727,500 (*see note below)
cubic yards @ $ 15/cubic yard

Maintenance and repair $ 10,000/yr $ 200,000 over 20 years
Note: *this may be reduced if excavation depth is reduced and f ll is used as berm
Estimated cost for 20 years operation: $1.1 M

Mechanical or Aerobic Treatment
The use of aerobic treatment technology is common in many applications. Industrial stormwater
is sporadic and mechanical or aerobic treatment is designed and operated optimally if the flow
and character of the liquid is consistent. The 40 MG generated in this estimate could be
introduced in small aliquots through a year, assuming uniform flow that is equivalent to a daily
flow of approximately I10,000 GPD. Mechanical or aerobic system costs typically range
between $10 and $151 gallon to achieve simple BOD and TSS removal. A system designed for a
flow of 110,000 GPD would have the following costs:
Description Cost
Aerobic system 110,000 GPD x 10/gal $1.1 M
Equalization for 2 MG event flow (6.2 ac - ft): $ 75,000 for the
assume 6 foot excavation and simple equalization

• Repair
$ 10,000/yr
Estimated cost for 20 years operation: SI AM
$ 1.2 M
$ 12,000
$ 200,000 20 years
Anaerobic Treatment
The use of anaerobic treatment technology is less common than the aerobic system in many
applications where blow strength water requires treatment. Industrial stormwater is sporadic and
anaerobic treatment with mixing is designed and operated optimally if the flow and character of
the liquid is consistent. The 40 MG generated in this estimate could be allocated in small aliquots
through a year, assuming uniform flow that is equivalent to a daily flow of approximately
110,000 GPD. Anaerobic wastewater treatment systems require extensive retention time,
typically liquid remains in a reactor for up to 30 days. Treatment of the anticipated 110,000 GPD
flow would require an anaerobic reactor containing 3.3 MG. This could be a deep, covered (leak
proof] mixed earthen basin reactor. Assume 15 feet depth then the reactor volume necessary is
approximately 1 acre. The reactor requires a liner completely encompassing the volume. Assume
a 40 ml liner enveloping a 1 acre excavation, with 1:2 sideslope and a 15 foot depth, then the
square footage of liner is estimated as103,000 square feet. Typical cost for lined excavation is
10/sq ft and this lined reactor would require $1.03 in addition to the excavation costs estimated
as $360,000 or approximately $1.4M. Optimum anaerobic digestion requires mixing and mixer
costs are typically $10,000 to $12,000 each. For this installation, a minimum of three (3) mixers
are necessary bringing cost to approximately $1.45M.

In addition, operation, maintenance, monitoring and repair costs would bring total cost for 20
years to $1.65M.
Wetland Systems
Conventional treatment methods are expensive. Engineered wetlands offer a natural system
approach to handle the industrial stormwater generated at Unilin. Testing indicates a hybrid
wetland system with both free water surface areas and subsurface flow areas provided treatment.
Engineered wetlands offer an approach which may be much better suited for the sporadic nature
of stormwater runoff from the Unilin facility. Wetland systems have been successful for other
water sources although application treating moderately high strength industrial stormwater would
be a new and novel application for this technology. Preliminary planning for a wetland approach
suggest a series of processes which include: enlarging the holding basin currently in place,
optimize the design of the actual wetland and assess plant species best suited to meet unique
treatment needs at Unilin. This current approach resulted from a pilot project which allowed
examination of several treatment configurations and determining the one that was most
successful at removing the elevated COD and TSS.
Treatment wetlands are a dynamic biological system. This suggests that there are a significant
number of variables and pollutant removal could vary depending on a number of variables. Also,
. since wetlands involve a collection of living organisms, there would be a need for a good deal of
hands on maintenance similar to maintaining a garden. While the downside meant that
maintaining a steady treatment of the water would be difficult, the upside would be that the
wetland could be maintained in a viable state during times of little or no flow where the other
treatment options would collapse. After all variables have been considered, an engineered
wetland seems our best choice even when its limitations are included.
The initial monitoring of test wetlands at Unilin suggests an area of four (4) acres is necessary to
accommodate the equalized stormwater flow from the design event. The minimum treatment
items necessary consists of the equalization area, two (2) independent treatment wetlands each
with a minimum of 1.5 acres and a single one (1) acre polishing wetland. Liquid would now
from equalization through the treatment wetland to the polishing wetland and ultimately enter an
intermittent stream on Unilin property.
Cost estimates discussed by representatives from Unilin suggest preliminary cost figures of
$600,000 to $650,000 for development of the hybrid surface flow/subsurface flow wetland
system assessed during this project. Ideally those studies could be extended for another year to
fully document the performance of the hybrid wetland system. This additional testing is
necessary to operate the maturing wetland during a cool season. The initial testing followed
• wetland system performance through a warm season, but the wetland was in development in the
cool season and root systems vital to system function were poorly developed. Extending the
monitoring protocol would allow collection of additional design information necessary to

•
•
optimize the wetland sizing. Regardless of the decision concerning the requested extension, costs
associated with development of the wetland include:
Description
Expansion of the initial holding area to 1.5 Ac and improvement of
solids removal
Installation of floating pump inlet
Construction of the two each 1.5 acre cells @ $ 75,000/ac
Construction of subsurface "islands" @ $ 50,000 each
Vegetation establishment
Surface and subsurface piping and distribution
Construction
Operation and maintenance for 30 days/year @ $ 200/d
Repairs $ 20,000/ yr
Estimated cost for 20 years operation: $1.1 M
Cost
$100,000
$ 25,000
$ 225,000
$ 100,000
$ 50,000
$ 100,000
$ 600,000
$ 6,000
$ 400,000 20 years
Regardless of the final decision, Unilin must obligate significant capital to develop a stormwater
system to accommodate the industrial stormwater generated at the Mt. Gilead facility. Data
collected in support of the approved demonstration wetland system assessment suggest that a
constructed or engineered wetland combining the properties of both surface flow and subsurface
flow is capable of achieving moderately high levels of pollutant removal. Data from published
sources confirm wetland systems achieve high levels of pollutant removal.
The industrial stormwater generated at Unilin is atypical of most stormwater; TSS and COD
levels are moderately high. Ideally the demonstration could continue for an additional year to
assure the design criteria utilized will meet the limits imposed. Further extension of the test
period will allow development of more thorough operating criteria for a treatment system.

Pilot Tests Procedure
After a rain event of sufficient quantity a pumper truck would transfer the collected stormwater
from basin number 3 to the three pilot wetlands, filling each to within about a foot and a half
from the top. Initial samples were taken within 24 hours of the transfer. Sampling was done at
each outflow pipe after allowing water to flow approximately 3 to 5 minutes. A second sample
was taken approximately two weeks after the start of the test run and a third sample was taken
approximately three weeks after that.
• Samples were preserved per PAR Labs requested protocol, including packing them in ice, and
were delivered to the lab within 24 hours of sampling. Rainfall totals for each event are recorded
on the accompanying test data tables.

UPDATE: Stormwater Permit Renewal
Dear Contact for Stormwater Permit No. NCG210354:
Effective August 1, 2013, the Stormwater Permitting Unit will move from the N.G. Division of Water Quality to the N.C. Division of Energy, Minerals, and Land
Resources.
This transition coincides with the expected effective date of the new NCG210000 Industrial Stormwater General Permit. Our Unit's move may mean a delay in
the issuance of that General Permit.
Your facility should continue to operate under the terms of your current permit. Any delay as a result of this reorganization will not be considered a lapse in
your permit coverage. The draft NCG210000 permit is open for public comment until July 17'h (please see http:Uporta1.ncdenr.or web/wg/w$/_s_ujcurrent-
notices). Once that process is complete, the new General Permit will be finalized and issued. At that time, we will send out an e-mail notification, including a
unique PIN and website link where the permittee can download the new Certificate of Coverage (COC).
distributing those e-mail notifications between July 31" and August 91h. If you have any questions, please contact Bethany Georgoulias at (919)

Subject: Unilin stormwater project
Dear Ms. Henson:
Our preliminary tests indicate that the wetland systems are removing pollutants
of concern and during the upcoming year we plan to refine our stormwater
management efforts. Our initial testing was accomplished by simply transferring
stormwater collected near the bottom of our primary storage pond to the
designed wetland systems. In phase two we will begin the design process for the
initial settling pond and begin removing clarified liquid from the upper zone of the
stormwater pond and transfer that under controlled conditions to the test wetland
cells.
The design of the initial settling pond is critical to the function of the wetland cell.
That design effort will be accomplished primarily by our process consultants, Phil
Rahn, Robert Rubin and our team of engineering consultants. The initial pond
design phase will begin in early 2013 and should be completed by the late spring.
The wetland testing will continue through both a cool season
(December/January/February) and a warm season (April/May/June). Wetland
systems are sensitive to temperature and the intent of this ongoing testing is to
assure that the wetland systems will achieve the water quality goals established
by NCDENR-DWQ. The testing will follow a batch of stormwater through the
wetland process. The intent is to utilize the initial storage as an equalization
system and the wetland cells as the treatment phase. The 3 to 5 week holding
phase is intended to mimic the patterns of heavy storm activity in the area.
Monitoring will proceed as before with time and concentration gradient patterns
developed through the effort. The monitoring effort will continue to assess the
standard water quality parameters monitored in phase 1 of the project. In
addition, Dissolved Oxygen, pH, and conductivity will be monitored. These are
important process parameters necessary to assess wetland system performance.

These process parameters are not compliance measures, rather indicators of the
wetland function.
The monitoring effort will conclude with a final report. This report should be
completed by late summer, 2013. Upon review of the report, a system will be
designed to accommodate the design storm events specified for this facility.
Once the report is submitted, reviewed, and comments evaluated, a final design
report will be submitted and construction will begin by late 2013. This
design/construction cycle is consistent with requirements for establishing plant
material in the treatment wetland. Typically establishing wetland plants is
accomplished early spring.
In summary, the proposed stormwater project development will be accomplished
in six (p) phases. These are presented in the figure below.

Stormwater Wetlands Project
Status as of 11/14/2012
Due to elevated nutrient and solids levels in stormwater runoff from a wood storage area
some form of treatment of the runoff was needed. Conventional technologies were
eliminated because the intermittent nature of stormwater would render them inoperable. It
was eventually determined that an engineered wetland would be the best technology
available. A pilot project was then agreed upon. Three separate wetland ponds were
prepared, each 24 feet by 41 feet. A drainage system was installed allowing water depth
to be adjusted and the ponds to be fully emptied when needed. Pond number one was
standing water only, pond number two was standing water and subsoil and pond number
three was standing water and subsoil islands.
The original detention basin was modified to hold water rather than metering the flow.
When an adequate rain event occurred, in excess of/2 inch, the three ponds were drained,
water was pumped from the basin and trucked to the ponds and the ponds were filled with
approximately 10,000 gallons of the runoff.
Initial samples were drawn from the drainage system within one day of filling the ponds.
Water was allowed to drain for about five minutes to clear the system before the samples
were taken. A second set of samples was taken approximately two weeks after the ponds
were filled and a third set after approximately three weeks more. To date three separate
test runs have occurred. The results are attached.
After the three test runs the study was evaluated. It was decided that a better way of
pumping the water from the detention basis was needed. Originally a hose was simply put
into the water, but it was determined that excess sludge was being sucked up in the
process resulting in elevated solids. Because of that, a device was fabricated to draw the
water from approximately six inches below the surface, thus lowering the solids and more
closely imitating what the final design for a full sized treatment system will utilize. As of
this date this method has not yet been used.

UNILIN
Stormwater Wetlands Project
Status as of 11/14/2012
Due to elevated nutrient and solids levels in stormwater runoff from a wood storage area
some form of treatment of the runoff was needed. Conventional technologies were
eliminated because the intermittent nature of stormwater would render them inoperable. It
was eventually determined that an engineered wetland would be the best technology
available. A pilot project was then agreed upon. Three separate wetland ponds were
prepared, each 24 feet by 41 feet. A drainage system was installed allowing water depth
to be adjusted and the ponds to be fully emptied when needed. Pond number one was
standing water only, pond number two was standing water and subsoil and pond number
three was standing water and subsoil islands.
The original detention basin was modified to hold water rather than metering the flow.
When an adequate rain event occurred, in excess of/z inch, the three pond's were drained,
water was pumped from the basin and trucked to the ponds and the ponds were filled with
approximately 10,000 gallons of the runoff.
Initial samples were drawn from the drainage system within one day of filling the ponds.
Water was allowed to drain for about five minutes to clear the system before the samples
were taken. A second set of samples was taken approximately two weeks after the ponds
were filled and a third set after approximately three weeks more. To date three separate
test runs have occurred. The results are attached.
After the three test runs the study was evaluated. It was decided that a better way of
pumping the water from the detention basis was needed. Originally a hose was simply put
into the water, but it was determined that excess sludge was being sucked up in the
process resulting in elevated solids. Because of that, a device was fabricated to draw the
water from approximately six inches below the surface, thus lowering the solids and more
closely imitating what the final design for a full sized treatment system will utilize. As of
this date this method has not yet been used.

Dear Ms. Henson:
This letter is to update you on the status of our engineered wetland pilot units. Construction on
the three pilot units began on October 315t, 2011 and was completed on November 23, 2011
when plants were introduced and the units were filled for the first time. The dimension of each
cell is 20' x 41.5' x 4.5'. The three wetland units are surface wetland, subsurface wetland, and
a hybrid wetland. The wetland units utilize tire chips, gravel, and topsoil as media to support
the vegetation and contain an assortment of white water lilies, broad leaf cattails, salt bush,
duckweed, pickerel weed, bulrush, common three square, inkberry, and wax myrtle.
As communicated in my letter to you dated October 13, 2011 we have started water testing in
December and will continue to test through September 2012.
I am including a CD of pictures detailing the, construction of the wetlands for your review. If you
have any questions do not hesitate to contact me.

Subject: Stormwater treatment system
Dear Ms. Henson:
DWQ
Thank you for joining us in visiting the New Hanover County Landfill Engineered Wetland
Project on September 29th, 2011. The visit proved very informative and moves us along the
path to returning to full compliance with our stormwater permit.
As per our agreement on September 29th I am submitting this letter to update our timeline due
to the addition of pilot wetlands in our project scope. In the new scope there are six phases in
the project.
1. Stormwater sample collection and rain intensity measurement
2. Construction of four pilot wetland units and measurement of their performance
3. Refining the design of the wetland treatment system based upon stormwater constituent
concentration and pilot unit performance
4. Increasing the size of the current holding basin
5. Constructing the initial wetlands
6. Testing the wetland discharge and adding additional wetland area if required
The six phased approach to address the industrial stormwater system at Unilin involves:
1. Stormwater sample collection and rain intensi measurement: This phase of the project
began in July of 2011 and will proceed through December, 2011. During this period we are
gathering data on at least five rainfall events of greater than 1 ". This intensity is necessary
to reflect the process load (BOD, COD, etc.) required in design for the stormwater system.
Unilin has purchased a weather station at a cost of $1,800 that will collect intensity and
volumetric data on all rainfall events. Additional cost in Phase 1 will involve $5,000 in lab
testing. This data, when combined with stormwater sampling, will provide the detailed
information required to accurately classify the constituent concentrations in the stormwater.
149 Homanit USA Road • P.O. Box 69 • Mount Gilead, NC • 27306 • [phone]

2. Constructing four pilot wetland units and measuring their performance
This phase of the project will encompass constructing four pilot engineered wetlands on
the Unilin site at an estimated cost of $65,000. Construction will begin in the fourth quarter
of 2011 and will be completed by December 31, 2011. This phase will last until September
�011 at which time we will have solid data on the engineered wetland's performance in
�m 12 both cold weather and warm weather conditions.
3. Refining the design of the wetland treatment system based on stormwater constituent
concentrations and pilot unit performance: The design phase of the project involves
optimizing the capacity of the initial receiving pond, optimizing the capacity of the pump
station required to lift partially treated stormwater into the treatment wetland and finally
optimizing the size of the wetland. The wetland sizing will be based on the assessment of
the stormwater quality collected in Phase 1, the performance of the pilot units, the required
hydraulic capacity necessary, and the process requirements necessary to reduce pollutant
concentrations to acceptable levels. This process will begin upon completion of data
collection accomplished in Phases 1 and 2. The design assessment will be completed by
December 31, 2012 at an estimated cost of $50,000. Upon completion of the design, the
project will be submitted to the Department of Water Quality for comments. Assuming a
three month review and feedback process, the required receiving pond and pump station
development can begin by April 1, 2013.
4. Increasing the size of the existing holding basin: This phase of the project will involve
removing an estimated 500 cubic yards of material from the existing pond system to
increase capacity in this initial receiver. Based upon an estimated cost $20/cubic yard for
soil removal and handling the earthwork portion of this phase will cost $10,000. Additional
costs in this phase will include $50,000 for engineering/ surveying, and $80,000 to install a
pump lifting station. Pump station development involves construction of a pump system
capable of delivering the liquid from the pond system to. the wetland. Phase 3 will be
completed by August 1, 2013.
5. Constructing the initial wetland: Upon completion of the pond and pump station
improvements, the development of the initial wetland system will proceed. The initial
system will consist of a treatment wetland designed to accommodate the measured flow
and to process the various limiting pollutant loads contained in the liquid. The constructed
wetland system installation will be completed by May 1, 2014 weather permitting. if the
construction season is beset by poor weather, construction may be delayed. The estimated
cost of Phase 4 is $400,000 based upon a cost of $5/square foot for wetland construction.
6. Testing the wetland discharge and adding additional wetland area if required: This phase
will involve testing the discharge from the wetland to verify compliance with our permit. If
additional treatment is required then additional cells will need to be constructed at this time.

Dear Mr, Aikman:
Dee Freeman
Secretary
Our office is in receipt of the additional information requested in our May 13, 2011 letter to you regarding the proposal for
a constructed wetlands system to aid in the reduction of levels of COD in stormwater discharges. Upon staff review of the
original request and subsequent additional information, the Fayetteville Regional Office of the Division of Water Quality
has no objections to your proposal.
Please be advised that the Tier Two monthly monitoring requirements as detailed in the NCG210000 general permit
remain in effect until such time as there are three consecutive monitoring events that show all parameters are below the
Benchmark Values listed in the permit. Also, should the constructed wetlands fail to perform as expected and Benchmark
Values continue to be exceeded, a subsequent Plan of Action will need to be considered and submitted for our review.
As mentioned in our May 13, 2011 letter, an approved erosion control plan issued by the Division of Land Resources,
Land Quality Section must be obtained prior to any land disturbing activity of one acre or greater.
During the March 15, 2011 meeting at your facility to discuss the subject proposal, outside observations were made of
significant amounts of a fibrous material, or perhaps sawdust, located adjacent to several buildings as well as near
stormwater conveyances. The housekeeping program established for the facility as required under the Stormwater
Pollution Prevention Plan section of the general permit may need to be re-evaluated and the frequency increased so as to
reduce and/or prevent unnecessary exposure that could contribute to the levels of COD present in stormwater runoff.

Subject: Stormwater treatment system
Dear Ms. Henson:
June 29, 2011 JUN 3 0 2011
®WQ
Our colleagues, Mr. Phil Rahn and Dr. A. R. Rubin, the professional staff. at Unilin, and I
propose the following as a project development and monitoring plan to accommodate the
process stormwater system for Unilin that was discussed during our meeting March 15, 2011.
This letter will provide the additional project detail requested in your May 13, 2011 letter
regarding the proposed Unilin Stormwater Treatment System. It is our understanding that the w
town manager of Mt. Gilead is communicating with you directly regarding your requested letter
clarifying that the city cannot handle our stormwater in the existing treatment plant.
As detailed in our letter to you dated April 11, 2011 there are five phases of this project.
1. Stormwater sample collection and rain intensity measurement
2. Refining the design of the wetland treatment system based upon stormwater constituent
concentration
3. Increasing the size of the current holding basin
4. Constructing the initial wetlands
5. Testing the wetland discharge and adding additional wetland area if required
The five phased approach to address the industrial stormwater system at Unilin involves:
1. Stormwater sample collection and rain intensity measurement: This phase of the project will
begin in July of 2011 and proceed through December, 2011. During this period we need to
gather data on at least five rainfall events of greater than 1 ". This intensity is necessary to
reflect the process load (BOD, COD, etc.) required in design for the stormwater system. If
we should not see rainfall in this amount during this period it is possible that we would need
to delay the start of Phase 2 until which time we are able to collect the required data. Unilin
has purchased a weather station at a cost of $1,800 that will collect intensity and volumetric
data on all rainfall events. Additional cost in Phase 1 will involve $5,000 in lab testing. This
data, when combined with stormwater sampling, will provide the detailed information
required to accurately classify the constituent concentrations in the stormwater.

2. Refining the design of the wetland treatment system based on stormwater constituent
concentrations: The design phase of the project involves optimizing the capacity of the
initial receiving pond, optimizing the capacity of the pump station required to lift partially
treated stormwater into the treatment wetland and finally optimizing the size of the wetland.
The wetland sizing will be based on the assessment of the stormwater quality collected in
Phase 1, the required hydraulic capacity necessary, and the process requirements
necessary to reduce pollutant concentrations to acceptable levels. This process will begin
upon completion of data collection accomplished in Phase 1. The design assessment will
be completed by April 30, 2012 at an estimated cost of $50,000. Upon completion of the
design, the project will be submitted to the Department of Water Quality for comments.
Assuming a three month review and feedback process, the required receiving pond and
pump station development can begin by August 1, 2012.
3. Increasing the size of the existing holding basin: This phase of the project will involve
removing an estimated 500 cubic yards of material from the existing pond system to
increase capacity in this initial receiver. Based upon an estimated cost $20/cubic yard for
soil removal and handling the earthwork portion of this phase will cost $10,000. Additional
costs in this phase will include $50,000 for engineering/ surveying, and $80,000 to install a
pump lifting station. Pump station development involves construction of a pump system
capable of delivering the liquid from the pond system to the wetland. Phase 3 will be
completed by the end of 2012.
4. Constructing the initial wetland: Upon completion of the pond and pump station
improvements, the development of the initial wetland system will proceed. The initial
system will consist of a treatment wetland designed to accommodate the measured flow
and to process the various limiting pollutant loads contained in the liquid. The constructed
wetland system installation will be completed by September 30, 2013, weather permitting. If
the construction season is beset by poor weather, construction may be delayed. The
estimated cost of Phase 4 is $400,000 based upon a cost of $5/square foot for wetland
construction.
5. Testing the wetland discharge and adding_ additional wetland area if required: This phase
will involve testing the discharge from the wetland to verify compliance with our permit. If
additional treatment is required then additional cells will need to be constructed at this time.

Wetland treatment systems are recognized as cost effective options to protect environmental
quality. The long term operation and maintenance cost of the system are estimated at $14,800
annually and can be broken down into the following areas:
1. Operator time: 10 hours/week at an hourly rate of $151hr = $7,800 annually
2. Monitoring: quarterly sampling@ $500.00 quarter = $2,000 annually
3. Asset management: $5,000.00 annually
As we move forward on this project we feel it would be best for all parties involved to visit the
wetland treatment system currently in service in New Hanover County near Wilmington. I
propose that we coordinate a date in the third quarter of 2011 to visit this site together to better
understand the system that will be installed. It is our desire to maintain lines of open
communication between Unilin and the Department of Water Quality. We recognize that
treatment of industrial stormwater provides challenges to both industry and regulatory agency
personnel.

We appreciate you, your staff, and your colleagues; Mr. Rahn and Dr. Rubin, for the time and assistance provided during our meeting at
your facility on March 15, 2011 to discuss the proposal of a constructed wetlands system for management and treatment of stormwater
discharges from the Unilin facility located in Mt. Gilead, Montgomery County, NC. Our office is in receipt of your letter dated April 11,
2011 outlining your proposal, timefrarne, and projected level of treatment for a constructed wetlands system. After staff review and
discussions, we have a request for the following information prior to supplying any additional comments:
1. Please provide our office with a cost analysis break -down for installation as well as continued operation and maintenance
of the proposed wetlands system.
2. Provide documentation and/or correspondence from the Town of Mt. Gilead concerning the potential, or lack thereof, for
conveying runoff from the wood chip stockpile to their sanitary sewer collection system and wastewater treatment plant.
You are asked to provide this information to our office on or before June 30, 2011. If you need additional time to submit this
information, you must submit a formal request by mail or fax indicating a reasonable timeframe that you expect to be able to submit the
requested information.
With respect to the size of the proposed wetlands system, there would be a requirement for your company to obtain prior approval of an
erosion control plan through the Division of Land Resources, Land Quality Section here at the Fayetteville Regional Office. Approved
erosion control plans are required for any land -disturbing activity of one acre or more. Based on implications supplied in your letter, the
project area for the constructed wetlands system would be approximately five to six acres, therefore triggering the need for submittal of
an erosion control plan to Land Quality for their review and approval prior to commencement of the land -disturbing activity for
installation of the wetlands system. If you or your staff needs assistance in this matter, you may contact the Land Quality Section at
910-433-3300.

Dear Ms. Henson;

Our colleagues, Mr. Phil Rahn and Dr. A. R. Rubin, the professional staff at Unilin and I propose the following as
a management and monitoring plan to bring the stormwater discharge from Unilin into compliance with our
permit. The initial design calculations presented herein are based on limited actual data comparing water quality
and storm intensity. Consequently, the initial phase of this effort involves a more thorough characterization of
the stormwater at the facility. This will involve Unilin purchasing a sophisticated rain gauge that will record
rainfall volume as well as intensity. This will be utilized to collect detailed data following rain events.
Stormwater collected in the pond system will be sampled following these events to assess the quality of the
stormwater emanating from storm events. These data will be used to optimize the size of the wetland system
necessary to accommodate the liquid generated at the site.
The five phase approach to this project involves:
1.Stormwater sample collection and rain intensity measurement
2. Refining the design of the wetland treatment system based on stormwater constituent concentration
3. Increasing the size of the existing holding basin
4. Constructing the initial wetlands
5. Testing the discharge from the wetlands and adding additional wetlands if needed
In order to guarantee the accuracy of the design and to keep the costs to an acceptable level Unilin will
complete phases 1 and 2 in calendar year 2011. Phase 3 will be completed in calendar year 2012. Phase 4 will be
completed in calendar year 2013. Phase 5 (if required) will be completed in 2014.

A very preliminary wetland proposal follows, this demonstrates the process to be utilized for sizing the wetland
treatment system based on more representative water quality information.
The combination of an enhanced pond followed by a treatment wetland will provide an adequate treatment for
the liquid generated at the Unilin Facility near Mt. Gilead. Constructed wetlands are recognized as an efficient
and effective wastewater treatment process in literature and in practice. Pollutant removal efficiencies in excess
of 85% are achievable for organic and suspended pollutants; nitrogen transformations result in denitrification,
and regulated metals are bound into organisms populating the wetland.
Treatment wetlands have been utilized effectively to remove pollutants from a variety of waste -streams. The
USEPA, WEF, and published commercial literature provide thorough standards for development of treatment
wetlands. Wetland systems can be developed as surface flow systems, subsurface systems, or reciprocating, fill
— and — draw systems. A typical wetland is depicted in figure 1, below. The treatment wetland proposed
incorporates elements of a subsurface flow wetland, a surface flow wetland, and deeper permanent pond zones
to assure some moisture is available for wetland plants and microorganisms through the year.

Figure 1, Typical Wetland Liquid
Liquid enters the wetland along a distribution manifold located near the surface of the system. Liquid flows
through a typical wetland system and exits through a water level control structure. The variable level allows
operators to adjust retention time in the wetland and optimize treatment.
Retention time in wetland systems range from 14 days to over four weeks depending upon weather. The
proposed system is designed to accommodate two back to back events and hold that liquid for 14 days. The goal
of a wetland system at Unilin is to provide effective treatment for high storm events. Previous studies indicate a
flow of 2 million gallons of stormwater would be generated in back — to — back storm events. Since the flow is
intermittent and the time between these storm events is variable, a wetland system can be designed to store
and treat liquid in a defined time period.
For purposes of design a retention time of 14 days is recommended. Assuming two significant events occur in
the two week period, the 2 MG capacity is necessary. A portion of the volume of a wetland is occupied by inert
material such as rock. This inert material provides media for organisms to develop and thrive. Consequently
volume in the wetland cell must allow for liquid and inert substrate. Minimum hydraulic volume required in a
system is calculated as:

2,200,000 gal/7.48 gal/cu ft. = 294000 cubic feet or approximately 6.5 acre feet.
In addition, the volume of inert fill material or substrate must be included and this will increase volume to
approximately 9 acre feet. An area containing 3 to 4 acres with 3 feet of liquid provides this volume. In addition
to the liquid level, a freeboard depth of 2 feet is required, bringing the depth to 5 feet. Process calculations
presented below suggest a 6 acre surface area is required.
The three to four acre surface area is suitable to accommodate the anticipated organic load entering the
wetland from the pond system. Water quality tests suggest typical or average TN, BOD and COD levels of 15, 150
and 270 mg/I respectively.
Since the flow into the wetland system is sporadic the entire volume is dedicated to the treatment of the single
event batch or the combined back-to-back stormwater batches. Liquid could remain in the wetland cell for
weeks and the discharge controlled by adjusting the height of the liquid in the level control structure. Slowly
lowering the level allows retention of liquid for extended periods of time and treatment improves with time.
Typical retention time in wetland cells is 14 to 21 days. Typical design criteria for wetland systems is 10 days.
The anticipated retention time in the process water treatment wetland exceeds the typical design criteria.
Calculations for BOD, COD and TN loadings are based on the following:
TN: 15 mg/I (typ) x 2.2 MG x 8.34 = 272 lb.
BOD: 150 mg/I x 2.2.8.34 = 2717 lb.
COD: 270 mg/I x 2,2 x 8.34 = 4918 lb.
These inputs are totals compounded from several storm events, more typical TN, BOD and COD loads per event
are estimated to be significantly less than these calculated values. Consequently the initial project phase
involves assessing water quality as correlated with storm intensity and retention in the pond system. Typical
design loads for a typical storm are estimated to be less than 60 lb. TN, less than 700 lb. BOD and less than 1500
lb. COD per event. Surface loading criteria for wetland systems based on these typical area loads are:
TN: 60 lb. -TN/12 lb.-TN/ac/d = 5 ac
BOD: 700 Ib. - BOD/140 lb. - BOD/ac/d = 5 ac
COD (No established criteria are available, but assume 300 lb./ac) 1500 Lb. - COD/300 lb. -COD/ac/d - 5 ac
The determining factors are TN and BOD. Based on this, a 5 acre wetland is required to assimilate the process
load expressed as nitrogen. CN ratios in the system are within ranges typical for wetland systems and the
wetland system is capable of achieving acceptable treatment without input of supplemental nutrients. The N
level is expressed as a TN value, should levels of readily available nutrients be insufficient, then supplemental N,
P, and K may be necessary to support growth of microorganisms required in treatment. Again, that amplifies the
need for the testing proposed.

The 2.2 MG design proposed will accommodate a total hydraulic flow of approximately 24 MG of stormwater in
a year. The anticipated storm frequency and intensity generates less than the 24 MGY potentially treated. The 2
MG capacity appears adequate to accommodate the design storm events.
The 24 inches of rain associated with hurricane events in September 2004 would result in some discharge from
the wetland system. The back-to-back storm events within 14 days resulted in significant volumes of water in
the environment of North Carolina. This volume would compromise any of the systems utilized to treat and
renovate wastewater or stormwater. Because of the high variability in the flow from the facility, a large wetland
system will accommodate the volume of stormwater as well or better than any of the other mechanical
treatment options currently available and produce consistently effective treatment.
Land resources at the Unilin facility have been modified by land forming activities and "natural" soil horizons are
generally unavailable. Tests in these disturbed areas indicate very slow permeability, measured permeability is
reported in the 10E-6 range and below. This material is well suited as the impermeable area to host the wetland.
Soil resources on the site will require careful placement in small lifts and final compaction to provide a retention
berm for the stormwater wetlands. This process is timely and use of these stored soil resources will help
maintain reasonable costs.
The constructed wetland option is a viable option for Unilin. A surface area of 5 acres is required to assimilate
the reported levels of constituents contained in the process water. This area will accommodate the process
liquid for longer than necessary to facilitate decomposition of the organic constituents expressed as BOO. The
level of treatment provided by natural systems such as constructed wetlands meet stringent treatment limits. A
wetland option appears a cost effective and efficient treatment alternative for Unilin.
Please feel free to contact me if you have any questions regarding our projected timeline.

Subject: RE: Need Update on Unilin Mount Gilead Plant + Question On Ft Bragg Status
Ron,
Wanted to give you an update on Unilin. We had a meeting with them on Tuesday of this week and they are working
with Dr. Bob Rubin (NC State University) with plans to construct a wetlands treatment systems for the water that comes
off this site that appears to have the potential to be considered wastewater. They are going to send us a plan in writing
with details of a time frame that they plan to complete construction. Dr. Rubin believes that the constructed wetlands
will remove the BOD and COD from the water enough to meet NPDES limits. They plan to begin with a 2 cell wetland
system and if it does not remove the BOD and COD as needed they will add more cells.. I do have lots of questions if this
will work but I am glad that they are moving with solutions to this issue. I can continue to keep you updated if needed.
Thank you and have a good day.

Belinda;
No, we need an update and/or, final resolution. We were asked to hold the assigned NPDES permit open fcr further,
possible re -application by permittee. Any discharge of a pollutant that exceeds WQS is+a violation. Since no treatment.
was provided we returned the original NPDES permit application. There is still the question about this as a-stormwater
discharge.
On another matter, what is the plan for Ft. Bragg dechlorination issue to meet TRC compliance?

Belinda,
As we discussed I went back and reviewed what info I could find on Unilin. They did submit a NPDES application in 2007
because of high BOD, COD in their stormwater discharge. The local WWTP (Mt. Gilead ) did not have capacity for the
wastewater. We returned the application in Oct 2007 because they did not provide any treatment to met water quality
standards. In Jan 2008 you sent a letter in regards to a phone conversation and action items to be performed by the
Permittee. I could not find any information more current.

is there still a high BOD/COD issue with the stormwater?
If yes, who is to handle, stormwater permitting unit?
If no, provide documentation for file?
Thanks for your assistance.

Dear Ms. Henson:
On November 6, 2009 we received the results of stormwater analytical tests on samples taken by
PAR Labs on October 28, 2009. Chemical oxygen demand was 436 mglL, in excess of the 120
mg/L allowed in our permit. This is the fourth time we have failed to meet the required chemical
oxygen demand as specified in General Permit No. NCG210000. As required, we are notifying
you of this result.
The failure occurred at the outfall that you inspected during your previous visit to our site and is
due to the large quantities of wood chips, our primary raw material, that we store in that area. We
have contacted the environmental engineering firm Mid -Atlantic Associates and will be working
with them to develop a method to remediate this situation. We will keep you apprised of our
progress as we move forward on this project. Please contact me with any questions or guidelines
you might have.

Unilin
COC Number NCG210354
Montgomery County
Dear Permittee:
In response to your renewal application for continued coverage under stormwater General Permit NCG210000 the Division of
Water Quality (DWQ) is forwarding herewith the reissued stormwater General Permit. This permit has been reissued pursuant to
the requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement between the state of North
Carolina and the U.S. Environmental Protection Agency, dated October 15, 2007.
The following information is included with your permit package:
• A new Certificate of Coverage
• A copy of stormwater General Stormwater Permit NCG210000
• A copy of the Technical Bulletin for the General Permit
• Five copies of the Discharge Monitoring Report (DMR) Form
• Five copies of the Qualitative Monitoring Report Form
The General Permit authorizes discharges of stormwater only, and it specifies your obligations with respect to stormwater
discharge controls, management, monitoring, and record keeping. Please review the new permit to familiarize yourself with all
the changes in the reissued permit.
The more significant changes to the General Permit include the following:
• Permit cover page, second paragraph — The General Permit now may cover activities that DWQ determines to be similar in
either the process, or in the exposed materials, to the Timber Products Industry.
• Part I Section A — A new provision that facilities draining to 303(d) listed waters, or in watersheds with an approved TMDL,
may not be eligible for continued coverage at the next renewal of the General Permit.
• Part I Section B second paragraph — A new clarification that the permit does not authorize discharges that DWQ determines
are wastewaters.
• Part 11 Section A — The required contents of the Stormwater Pollution Prevention Plan have been expanded and clarified.
• Part ll Section B Table 1 — A new requirement to sample stormwater discharges twice per year for those facilities with
exposed piles of certain materials remaining on site longer than seven days.
• Part II Section B Tables 2 and 3 and following — For permittees with exposed piles, there are new provisions requiring the
permittee to execute Tier One and Tier Two response actions, based on the first benchmark exceedence (Tier One) and the
second consecutive benchmark exceedence (Tier Two). Tier Two requires that the permittee institute monthly monitoring
instead of twice -per -year monitoring, until three consecutive monitoring events show no benchmark exceedences.
• Part II Section B — For permittees with exposed piles, a new provision that four exceedences of any particular benchmark
will trigger increased DWQ involvement in the permittee's stormwater management and control actions. DWQ may direct
the permittee to apply for an individual permit, or may direct the implementation or installation of specific stormwater control
measures.
• Part II Section C — Clarification that under the qualitative monitoring provisions of the permit, the permittee is obligated to
respond to repeated observations of stormwater pollution. DWQ may impose additional stormwater management
requirements if the permittee is non -responsive, or if the responses are ineffective.
Your coverage under the General Permit is transferable only through the specific action of DWQ.

SUBJECT: Review of items in phone conversation (January 7, 2008)
Unilin US MDF
Mt. Gilead, NC 27306
Montgomery County
Dear Mr. Pierce,
This letter is for the purpose of reviewing the phone conversation that Belinda
Henson (Fayetteville Regional Supervisor, Surface Water Protection Section) and Dale
Lopez (Fayetteville Regional office Environmental Specialist, Surface Water Protection
Section) had with you on January 7, 2008 in response to your NOV reply letter to this
office, dated December 26, 2007.
From the phone conversation it was understood that:
I. There was a cooling jacket water leak that you became aware of after our visit to
your plant site on October 23, 2007, when Belinda Henson and Dale Lopez took
water samples at the Stormwater Forebay and at the Stormwater Management
Basin, 'and this leak could have been the cause for the high BOD and COD found
in the sampling that took place on October 23, 2007.
2. There was presently not any discharge from the Stormwater Forebay, and by this
statement it -was also understood by this Office that there was no discharge flow
from the Stormwater Management Basin.
3. In April 2008, this site will be scheduled for changing the cooling system from
water-cooling to air-cooling. An outside consulting firm (Mid-Atlantid
Associates, Daren McClure) is looking into the changeover project.
4. Keyes McGee, NCDENR Pollution Prevention group, has not sent his report to
you.

5. Two vacuum units, the "Billy Goat" and the "Little Wonder", will be viewed for
possible application at your site to clean up the sawdust and wood fibers. This
could possibly eliminate the water usage on the accumulated wood for the
purpose of fire prevention.
6. You agreed that next week you would phone this Office and supply us with the
following two items of information: a date that the leak will be fixed, and the
outcome of the "Billy Goat" and the "Little Wonder" demonstration.
7. This Office reiterated the importance of eliminating the discharge flow of high
BOD and high COD.
Please keep this office abreast of any developments that occur at you facility
that will be used to eliminate the high loadings of BOD and COD for the Unilin, Mt.

Dear Mr. Pierce,
On October 3, 2007, Dale Lopez (DWQ - Fayetteville .Regional Office) visited
your facility for a routine inspection that was associated with your application for an
NPDES Discharge permit for Unilin's discharge flow to an unnamed tributary, that then
flows to Disons Creek, to Little River, and finally to the Pee Dee River. During the site
visit, Mr. Lopez observed that there was ditch water flowing from the sediment forcbay
through the riprap filtration, into the stormwater management basin, and through the
stormwater riser effluent ports (four ports that each appeared to be between 2 to 3 inches
in diameter). Mr. Lopez observed approximately 2 to 3 gallons per minute of flow in
the ditchwater that was located on the effluent side of the Stormwater Management Basin
levee. He was told that the observed ditchwater flow was the effluent stream from the
Stormwater Management Basin. On June 25, 2007, PAR Laboratories sampled water
that flowed from the wood chip pile, and the laboratory results were submitted with the
NPDES permit application; the Biochemical Oxygen Demand (BOD) was 152 mg/L and
the Chemical Oxygen Demand (COD) was 227 mg/L.
On October 23, 2007, Belinda Henson (Fayetteville Regional Supervisor, Surface
Water Protection Section) and Dale Lopez visited the Unilin site, observed that there was
approximately 2 to 3 gallons per minute of flow in the effluent ditchwater on the outside
of the Stormwater Management Basin levee, and sampled the Forebay and the
Stormwater Management Basin. The laboratory results were as follows:

These Oxygen Demand loadings have the reasonable potential to produce
detrimental oxygen demands on the receiving stream. Please note that natural waters in
North Carolina are typically below 5 mg/L of Biochemical Oxygen Demand and that the
NPDES permit limits for wasterwater treatment plants are less than 45 mg/L weekly
average of BOD. It appeared that Unilin was creating a discharge that was high in
Biochemical Oxygen Demand and Chemical Oxygen Demand. This is considered as an
unpermitted discharge of wastewater. The flow, with such high BOD and COD, camiot
be allowed to enter the Waters of the State, and this discharge is required to cease
immediately. This office suggests the removal of the pollutants (high levels of BOD &
COD), or directing Unilin's discharge to the local Publicly Owned Treatment Works
(POTW). Please note that removal shall not mean dilution of the pollutants.
In accordance with the maximums established by G.S. 143-215.6A(a)(2), a civil
penalty of up to $25,000 may be assessed against any person who violates the terms,
conditions or requirements of a permit required by G.S. 143-215.1(a)(6). Please send a
written response to this office by December 28, 2007. Thank you for your cooperation
in this matter. if you have any questions concerning this letter, please contact me at

Mike,
Please see attached drawing. We may do some minor additions or
modifications but this is pretty much how it is going to work. The
rip -rap portion (the "filter" for the solids) would be replaced
annually. Total cost will be around $100,000 including engineering
costs. We will be in touch soon as we move forward with a permit
application. Hope this helps.

We have completed the survey of the stormwater basin and of the ditch that feeds it. Lockwood
Green has submitted preliminary drawings for both modifications to the basin and for the forebay
intended to remove solids and permit us to resume washdowns. Once we have finalized the
design we will solicit bids for the project.
We will also be working with Lockwood Green on the permit application. We will be supplying you
with further details as they become available.

Dear Ms. Henson:
JAN 2 Z 2007
CI-) I
Per your request in the letter dated January 4, 2007 please accept this written response and Plan
of Action addressing the observations you cited.
We intend to locate a flow sensor in our waste water line at the furnace. This would be an "end of
the line" location and so would let us know that there was an interruption of flow of our
wastewater somewhere before the furnace. We could stop pumping and prevent any significant
release should the flow stop.
We are retaining Concord Engineering and Surveying, Inc. to address several issues. They will
be repairing damage done to the stormwater basin during our cleanup. The repairs will result in a
BMP Wet Pond designed in accordance with the Draft Manual Of Stormwater Best Management
Practices. In addition, we will be exploring options that will allow us to resume the washdowns.
We intend to have an outside laboratory do BOD tests on representative samples of washdown
water. We are confident that, once the large particles, i.e. wood fibers, are removed our
washdown water will have no negative affects on the environment. For the present we will refrain
from doing any washdowns.
It is hoped that these actions address your concerns. Please let me know if you need further
clarification, added details or if you would like progress reports as we move forward.

Other Observations:
During the inspection, it was relayed that facility personnel discovered that there was a leak in the line,
which carries water that has been squeezed out of the wood chips to a furnace to be burned off. Since
this line is outside, the process water flowed into stormwater detention basin #3. The outlet structure for
detention basin #3 has an 8"-10" diameter hole near the bottom that does not allow for adequate
detention time and therefore the release of process water made its way to the receiving stream. Also
noted during the inspection, areas where wood fibers end up on the grounds of the facility are wetted
down multiple times during each week for fire prevention. This water also flows into stormwater
detention basin #3, which is not covered by the NCG210000 general permit.
Requested Response:
It is requested that the Fayetteville Regional Office of the Division of Water Quality be provided with a
written response and Plan of Action (POA) concerning the aforementioned observations. Both the
response and the POA should be mailed to the letterhead address within 15 days from receipt of this
letter. The response should provide details of the leak including date and time it was first noticed,
possible cause, nature of the water and schedule of repairs. The POA should discuss alternatives to
allowing the runoff from the wetting of fibers to flow into the stormwater basin.
Please be advised that violations of the NPDES General Permit are subject to a civil
penalty assessment of up to $25,000 per day for each violation. If you or your staff has any
questions, comments, or needs assistance with understanding any aspect of your permit, please do not
hesitate to contact Mr. Lawyer or myself at [phone]. ,

Inspection Summary:
Inspection conducted in response to a complaint concerning color and odor in a nearby creek, which receives stormwater
discharges from the facility. Ih investigating possible causes of the color and odor, facility personnel discovered that there
was a leak in the line that carries excess water from the pressing of steamed wood chips to their furnace. This water is
high in BOD due to the organic nature of the wood chips. Since the line is outside, the escaping water traveled into one of
the facility's three stormwater detention basins (basin #3) and subsequently into the receiving stream. In an effort to
reduce the potential for fires and passible explosions in regards to the highly combustible fibers, areas where fibers are
present on the grounds of the facility are wetted down multiple times each week. Runoff from this practice also travels
into basin #3 and then discharged. This runoff is potentially high in BOD as well. Although facility at the time of
inspection was found to be compliant with the conditions of the general stormwater permit, the runoff and subsequent
discharge from the intentional wetting of fibers is not covered under the stormwater permit.

Dear Ms. Henson:
This letter is intended as an update outlining actions Unilin is taking regarding repairs to our
stormwater basin # 3 and additions to that system that will allow us to resume performing
washdowns in our woodyard. We have retained the services of Lockwood Green to address both
the design phase of both portions of the project and to assist us in developing and submitting the
proper NPDES permit applications. As of this writing we are waiting for Lockwood Green to
supply us with survey requirements they deem necessary. That will be the first step in the
process. As we move forward we will keep you apprised of our progress and will work with your
office to assure a resolution that satisfies all environmental concerns. Please contact me with any
questions or suggestions you might have.
Once we have completed the design of the forebay that Lockwood Green feels will adequately
address the issues relating to the washdowns we will work with you to develop a testing protocol
that will assure that no adverse impact to the environment will result from this activity. We are
confident that we can develop a solution that satisfies all parties.

Attn: Bradley Bennett k,
Dear Mr. Bennett:
Unilin US MDF currently holds stormwater discharge permit COC Number NCG210354.
There are three stormwater basins on site, each with its own outfall. While each outfall
drains separate areas of the complex, they all share common stormwater characteristics.
None of them is affected by rolling stock maintenance, which is performed under roof. All
of them have some areas of paving that would impact them, and all of them have runoff
from wood materials, either bark/wood fuel, raw material in the form of wood chips or
pallets used in shipping or moving of final product.
None of the basins is subject to any chemical exposure.during normal operation. Since the
facility is recently built all tanks for chemical or fuel storage are in diked areas with no
outlets. The permit currently calls for testing of outfalls for pH, oil and grease and total
suspended solids. Since there is little difference between the drainage areas to the basins
we feel that testing the Northern Basin would yield sufficient data for monitoring
purposes. I have included a site map showing all three basins to help you with your
assessment.
During a recent inspection of our site Ricky Revels of your Fayetteville office suggested I
request Representative Outfall Status for our system, and that the Northern Basin be the
one that we would use for testing because it gets the heaviest loading. Please let me know
if more information is needed.

Per our telephone conversation of November 17 we are reporting the final
disposition of the oil release that occurred on November 16. The volume of oil
was less than originally thought, being approximately 50 to 100 gallons. Most of
the oil was stopped at our stormwater basin. A small amount was stopped by the
dam we had placed at the outfali. Cleanup was done by Shamrock
Environmental and was completed on Saturday, November 19, prior to our recent
rains. No oil reached- surface waters. Please let me know if you need further
information.

of letter that was sent to Bob Jordan, Jordan Lumber Company by Lisa Wilson,
F letter was dated August 13, 2002. In the letter, Ms. Wilson said that an oil
discharge occurred in Mt. Gilead's wastewater collection system. On Monday

to alarm. Oil was found in the lift station and was backtracked to Jordan Lumber.
Gene Thomas (of Jordan Lumber?) said that Jordan Lumber had experienced
problems with the wastewater system between 7:30 and S AM. Kearns Pumping
Service was already on your site and had already recently pumped Jordan
Lumber's system (?). Mr. Kearns said that he didn't know if there was any oil in
the water that he had pumped earlier. Mr. Kearns said that no oil could have
come from his vacuum truck and caused the oil spill. Mr. Kearns phoned Ms.
Wilson and said that there was oil at the manhole at Jordan Lumber. Then, after
meeting with Ms. Wilson, Mr. Kearns left the site without pumping any oil from
the manhole. Mr. Pearce of Homanit said that he. had checked Homanit and had
not found any oil problem coming from Homanit. In this letter to Mr. Jordan,
Ms. Wilson requested that Jordan Lumber have a contact person for that type of
