Dear Mr. Burke:
In accordance with the application for discharge permit received on November 4, 1998, the
Division is forwarding herewith the subject state - NPDES permit. This permit is issued pursuant to
the requirements of North Carolina General Statute 145-215.1 and the Memorandum of Agreement
between North Carolina and the U.S: Environmental Protection Agency dated December 6, 1985.
Significant.changes to the previously issued NPDES permit have been summarized below:
• The monitoring frequency for TSS and settleable.solids has been changed from 7 days/week to
daily. The more frequent sampling does not appear necessary because of the successful
implementation of the clear water system for solids removal.
• In accordance with the Division's revised Whole Effluent Toxicity testing requirements, which
became effective in 1996, the acute toxicity testing requirement has been modified to a chronic
test. The instream-waste-concentration (IWC) for ABTCO's discharge is 0.68%. Under the
previous requirements, those facilities with IWCs between 0.25 and 1.0 were assigned acute LC50
tests at 100 times IWC. The new test is a chronic pass/fail test at the IWC. Additionally, the
toxicity testing language has been updated to reflect the current format.
• All allocations for TSS, and therefore all effluent pages, prior to those effective as of January 1,
1997 have been deleted.
• "Special Condition F in the previous permit required ABTCO to submit quarterly reports indicating
efforts to minimize solids. This was a requirement associated with the TSS limits phase-in and is
no longer necessary as the more stringent limitations are in effect.
• Due t&ABTCO's participation-in-the-Yadkin-Pee Dee River Basin .4ssociation'(the Association),
instream. monitoring requirements have been .provisionally waived and stated as such on the
effluent limitations page.
• The previous permit required ABTCO to monitor instream turbidity. - Although the Association -"
did not adopt-a replacement station for this sampling; continued monitoring does-not appear
necessary. The Division of Water Quality operates an ambient station approximately 1.7 miles

downstream of the discharge while the Association's station is approximately 8.0 miles
downstream. As such, the instream turbidity monitoring requirement has been removed from the
permit.
If any parts, measurement frequencies or sampling requirements contained in this permit are
unacceptable to you, you have the right to an adjudicators hearing upon written request within thirty
(50) days following receipt of this letter. This request must be in the form of a written petition,
conforming to Chapter 150B of the North Carolina General Statutes, and filed with the office of
Administrative Hearings, Post Office Drawer 27447, Raleigh, North Carolina 27611-7447. Unless
such a demand is made, this permit shall be final and binding.
This permit does not affect the legal requirements to obtain other permits which may be
required by the Division of Water Quality or permits required by the Division of Land Resources,
Coastal Area Management Act, or any other Federal or Local governmental permits which may be
required.
If you have any questions or comments regarding these speculative limitations, please do not

SUMMARY
\BTCO owns and operates the country's largest manufacturing facility of single-smooth-side
hardboard siding for the construction industry. Startup began in 1970 with a second line installed in
1980. Facility representatives indicate that production has more or less peaked as fiber cement
siding is taking market share. ABTCO operates a fiber cement plant on-site, however all
wastewaters are recycled. The facility manufactures about 1,000,000 Ibs/day on average, equivalent
to approximately 870,000 square feet of siding.
The facility's raw material is wood that would ordinarily not be accepted at a sawmill. Approximately
8.5 suppliers within about 120 miles of the plant provide the incoming wood. The wood processed is
approximately 80% mixed hardwoods and 20% pine. The facility receives both chips as well as logs.
:A chipper on-site handles any logs received. The preliminary stages of processing are very similar to
that of a paper mill. Chips are washed and screened prior to digestion. The digester delignifies the
pulp leaving a fiber slurry_ Further refining brings the raw material to the "stock' stage. It is at this
point that the fibers are prepared for hardboard manufacturing. After the product is formed, it
contains only 2 — 3% solids. The final product must be about 96% solids, so a rigorous dewatering
process concludes the manufacturing process.
This facility is subject to federal guidelines (specifically, 40 CFR 429.61(a), Wet Process Hardboard
Subcategory for smooth-one-side hardboard, applies). Because production hasn't changed
significantly, either up or down, since the previous renewal, BOD, limits will not change- However,
TSS limits in the existing permit were negotiated in association with a settlement to a contested case
filed by ABTCO upon permit issuance in 1995. This facility has had a history of high effluent solids,
contributing to the degradation of the downstream habitat of the Yadlun River. Specifically, the
permit had increasingly stringent TSS limitations implemented in two phases. TSS limits were
phased in according to the schedule in table 1 below:
ABTCO Fact Sheet
NPDES Renewal
Page I

TABLE 1 Monthly Average Daily Maximum
Through January 1, 1996 27296 lbs/day 41388 lbs/day
Through December 31, 1996 14000 Ibs/day 21000 Ibs/day
Until Expiration 12000 Ibs/day 18000 Ibs/day
The limits effective from the issuance date of the permit until January 1, 1996 (the first row of the
above table) were calculated in accordance with the federal guideline cited in the previous paragraph.
The final limitations, as stated above, were negotiated and should not change with this permit
renewal. Settleable solids monitoring was installed with the previous renewal and monitoring for
TSS and settleable solids was established at 7days/week With the very successful implementation
of the clear water system (see Compliance Summary below), the 7days/week monitoring frequency
for these two parameters appears to no longer be necessary. The monitoring frequency will be
modified to daily, with daily defined as Monday through Friday excluding holidays.
Effective June 1, 1998, ABTCO became a participant in the Yadkin-Pee Dee River Basin Association
(referred to from here on as the Association) for conducting collective instream monitoring.
Upstream and downstream monitoring for temperature, dissolved oxygen, conductivity. and turbidity
was required of ABTCO prior to participation in the Association. Although the Association did not
pickup instream turbidity monitoring at the frequency required in ABTCO's permit, instream data
does not warrant continued monitoring as it appears the facility is having little to no impact on
instream turbidity.
The faciliq operates a 0.05 MGD package wastewater treatment plant for handling the sanitary
wastewater generated by its approximately 500 employees. The effluent from this package plant
discharges to the industrial waste treatment lagoon.
PROPOSED CHANCES:
• AlonitoringFrequencies: The monitoring frequency for TSS and settleable solids has been
changed from 7days/week to daily. The more frequent sampling does not appear necessary
because of the successful implementation of the clear water system for solids removal.
• Toviciq- Testing: In accordance with the revised Whole Effluent Toxicity testing
requirements outlined in Steve Tedder's October 14, 1996 memorandum, the acute toxicity
testing requirement has been modified to a chronic test. The instream-waste-concentration for
ABTCO's discharge is 0.68%. Under the previous requirements, those facilities with IWCs
between 0.25 and LO were assigned acute LC;,, tests at 100 times IWC. The new test is a
chronic pass/Fail test at the IWC. Additionally, the toxicity testing language has been updated to
reflect the current format.
• 7156 alloca ton: All allocations, and therefore all effluent pages, prior to those
effective as of January 1, 1997 have been deleted.
• Special Condition F Special Condition F in the previous permit required ABTCO to
submit quarterly reports indicating efforts to minimize solids. This was a requirement associated
with the -FSS limits phase-in and is no longer necessary as the more stringent limitations are in
effect.
• Tuibidiq .11onitoring: The previous permit required ABTCO to monitor instream
turbidip. Although the Association did not adopt rigorous instream turbidity monitoring,
continued monitoring does not appear necessary. A review of upstream and downstream data
suggests that ABTCO is not having an impact on instream turbidity. The Division of Water
Quality operates an ambient station approximately 1.7 miles downstream of the discharge while
ABTCO Fact Sheet
NPDES Renewal
Page

the Association's station is approximately 8.0 miles downstream. The instream turbidity
monitoring requirement has been removed from the permit.
• / stream MOnttoting: Due to ABTCO's participation in the Association, instream
monitoring requirements have been provisionally waived and stated as such on the effluent
limitations page.
TOXICITY TESTING:
Type of Toxicity Test: Chronic P/F
Existing Limit: 001: Acute LC,t, @ 68%
Recommended Limit: 001: Chronic P/F @ 0.68%
Monitoring Schedule: January, April, July, and October
The change in the type of toxicity test required is a reflection of a change in the Whole Effluent
Toxicity testing requirements outlined in Steve Tedder's October 14, 1996 memorandum.
COMPLIANCE SUMMARY:
The effluent from this facility is characteristic of a wood products industrial discharge- The effluent
experiences high conductivity and low dissolved oxygen, however considering the average stream flows
realized in this portion of the Yadkin River, little impact on instream dissolved oxygen levels is
expected. The facility has had little problem meeting its effluent limits with the exception of whole
effluent toxicity. Over the past four years, the facility has conducted 27 tests, 8 of which were
failures. However, since March of 1997, the facility has had no problems with meeting its toxicity
limit. Although effluent suspended solids have historically been quite high, with the implementation
of the clear water system, values are consistently below 1000 Ibs/day. Prior to this system's startup,
values were often between 5000 and 10000 Ibs/day.
INSTREAM MONITORING:
Instream monitoring is required for temperature, dissolved oxygen, and conductivity. All instream
monitoring requirements have been provisionally waived due to the facility's participation in the
Association.

Re: Renewal of NPDES Permit No. NC0005266
Dear Mr. McIntire,
Our permit is currently at the Division of Water Quality for renewal. We would also like
to request at this time the deletion of a monitoring and reporting requirement in the
permit. We are currently required to generate quarterly reports on the monitoring of the
flow and solids discharged from the DAF and clarifier. Our understanding is that these
requirements were related to the old permit that contained three different limits for TSS
discharge. The reports tracked the efforts made to reduce solids discharge from the
facility in order to comply with the changing limits. As the facility was able to successfully
reduce solids to the final discharge limits, we request that the monitoring and quarterly
reporting of this data be deleted from our permit.
Please take this request under consideration as you renew and rewrite our NPDES permit.
If you have any questions or concerns, please do not hesitate to contact me at my office,
Sincerely,
d V'

This change in wording is due to the fact that the in-line grinder has had a poor track
record and requires frequent maintenance as it appears unsuitable for our type of industrial
waste. The bar screen is always in place, but with frequent outages, we can not guarantee
that the in-line grinder is operational at all times. Additionally, we have found that the
cost to operate and maintain the grinder does not out outweigh the limited benefits of the
unit. Frequent cleaning of the manual bar screen provides equal benefit at lower
operational costs. This does not constitute a change to our plant or operation, simply it
reflects our experience in operating and maintaining this piece of equipment.
If there are any questions or concerns, please do not hesitate to contact me at my office.

Solids Reduction Evaluation
History: ABTco agreed to a reduction in wastewater treatment plant suspended solids
discharge to the Yadkin River. This reduction was due to concerns resulting from a river
study conducted in June of 1993 by the State of North Carolina. The allowable
wastewater discharge of solids was stepped down annually as construction of the Clear
Water system progressed at the plant. Modifications were made to optimize existing
sludge thickening equipment. In addition, new equipment to dewater the thickened sludge
was purchased, installed and brought on line. Significant capital costs were incurred to
increase the sludge wasting capacity of the sludge dewatering facility from 12 - 14 Oven
Dried tons per day to 28 - 30 O.D. tons per day. In addition, the dewatering facility is
configured to process the majority of the wastewater flow through the dissolved air
flotation (DAF)unit, whenever necessary to meet the more stringent standards. During
the summer months the wastewater treatment plant is able to discharge all of the effluent
through the secondary clarifier. For the remainder of the year, the wastewater treatment
plant must discharge the bulk of the effluent from the DAF in order to meet discharge
limits.
Current Status: Currently the system is working well and the Clear Water program
allows the wastewater treatment plant to meet existing effluent permit limits. The DAF
unit is currently at maximum operational capacity as it processes 500 gallons per minute
which produces 0.7200 MGD of clean effluent. The remainder 0.1300 of the effluent is
discharged via the clarifier. When the clarifier discharges such a low flow, 90 GPM, it
produces excellent quality effluent at almost all times of the year.
With the DAF unit operating at maximum hydraulic and solids loading, there is no
additional solids wasting capacity which can be readily accessed with existing equipment.
Therefore, there is little or no additional solids wasting ability in the existing wastewater
treatment system. Additional solids wasting capacity would require additional
construction and very significant capital expenditures to further lower wastewater
treatment plant solids discharge to the river.
To evaluate the current level of impact of the ABTco effluent discharge to the river,
ABTco commissioned a river study by George J. Pesacreta, Ph.D., of Ecological
Consultants. Ecological Consultants conducted an EPT study on the Yadkin River at the
Wilkesboro Reference Site, the Above ABTco Site and the Below ABTco Site. The
intent of this study was to duplicate the efforts of the State in their June 1993 study and to
evaluate any changes in the river that may have resulted from the reduction in solids

discharge. The study attached to this document shows that there have been some
significant changes in the river below the ABTco discharge. Although the Above ABTco
location was shown to have Good rating, both the Wilkesboro Reference site and the
Below ABTco sites had an identical rating of Good-Fair. In addition, these two sites had
virtually identical EPT abundance and EPT Taxa Richness numerical values leading one to
conclude that the water quality was the same at the Wilkesboro Reference site and the
Below ABTco site.
The findings of the greatest significance from this study were that"white fungal matter
observed by the State in 1993 was completely absent in this study. Also, the Podostemum
(river weed)which was not found in 1993 is now common below the ABTco discharge.
In addition, the discovery of an intolerant stonefly species (Pteronarcys dorsata)was
more common at the below ABTco site than at the other two sites. These are very
positive signs that the river is recovering and that the current level of solids in the ABTco
discharge to the river is not detrimental to the aquatic fauna and flora in the river.
Future Plans: ABTco intends to continue to operate the Clear Water system to maintain
compliance with current permit limits. Because the river study commissioned by ABTco
(see attached) demonstrates that the river is showing signs of recovery, ABTco feels that a
further reduction in solids discharge is not warranted. ABTco proposes to monitor the
health of the river through the Yadkin Pee-Dee River Basin Association which is now
conducting basinwide river sampling. In addition, ABTco will conduct EPT sampling on
the river upon the next permit renewal to try to document any impact to or recovery of the
Yadkin River. Because any changes in the river are slow to develop, more frequent
evaluation of the river would not be necessary.
Conclusion: Our current facilities are operationally at their limit for the removal of solids
from the waste treatment system. Addional solids removal would require very significant
capital and operational costs. The EPT study conducted in 1998 shows that the river
conditions have improved to where the water quality is substantially identical at the
reference site and the downstream location. ABTco feels that we have pursued the
reduction of solids discharge to the point where there is no degredation of water quality
below the ABTco outfall on the Yadkin River.

SUMMARY
ABTCO Inc. manufactures hardboard exterior siding from wood. Treated effluent from
the manufacturing processes are discharged into the Yadkin River near the plant facilities. In
1993, ABTCO initiated a plan to advance treatment efficiency and by 1996, the plant had
decreased effluent solids and B.O.D. discharge to the Yadkin River. This study examined benthic,
macroinvertebrates in the Yadkin River near the ABTCO plant. EPT samples were collected
from stations above(Above-ABTCO) and below(Below-ABTCO)the effluent outfall of the
ABTCO plant in the Yadkin River. Also, EPT samples were collected at a reference site
(Wilkesboro-Reference)near the USGS gauge near Wilksboro, North Carolina. Samples were
collected in June-July 1998.
Stream sediment composition differed along the reach of the Yadkin River studied. At the
Above-ABTCO and Wilkesboro-Reference sites, substrate was comprised of more rubble and
gravel than at the Below-ABTCO site. Sand and silt comprised forty(40) percent of the
substrate at the Below-ABTCO site. A riffle zone at the Below-ABTCO site was sampled by
entering the river from the bank across from the ABTCO plant.
The June-July sampling of EPT in the Yadkin River gave a Good bioclassification rating at
Above-ABTCO site and Good-Fair rating for Below-ABTCO and Wilkesboro-Reference sites.
EPT taxa richness and EPT abundance values were greatest at the Above-ABTCO site.
However,Pteronarcys dorsata, an intolerant stonefly species, was more common at the
Below-ABTCO site than at the other sites. Pteronarcys dorsata was not observed at the
Below-ABTCO site during collections completed by the N.C. Division of Environmental
Management(DEM) during June 1993. Also, the DEM reported for June 1993, "white fungal
material" and a lack of river weed (Podostemum) at the Below-ABTCO site. No fungal material
was observed at the Below-ABTCO site during this survey and river weed was common.
Because of the greater silt and sand substrate found at the Below-ABTCO site, habitat
differences influence benthic macroinvertebrate distribution, restricting the distribution of
intolerant benthic macroinvertebrates. However, the improvement in effluent quality from the
ABTCO plant may have contributed to the greater distribution of Pteronarcys dorsata below the
ABTCO plant in the Yadkin River. It is possible that we are now seeing recovery of the Yadkin
River near the ABTCO discharge illuminated by the establishment of Podostemum, absence of
fungal matter, and presence of more intolerant species(i.e.Pteronarcys dorsata) at the
Below-ABTCO site. Therefore, we recommend that future EPT taxa richness and abundance
studies be conducted upon permit renewal, when summer water flow in the Yadkin River is
minimal, to monitor the benthic macroinvertebrate community.

INTRODUCTION
Ecological Consultants examined EPT taxa richness, EPT abundances and bioclassification
ratings at three sites in the Yadkin River during June-July 1998. These results were compared to
data collected by the N.C. Division of Environmental Management (DEM)in June 1993.
EPT samples were collected from stations above(Above-ABTCO) and below
(Below-ABTCO)the effluent outfall of the ABTCO plant in the Yadkin River. Also, EPT
samples were collected at a reference site(Wilkesboro-Reference) near the USGS gauge near
Wilksboro,North"Carolina. These sites were previously sampled in June 1993 by the DEM
Biological Assessment Group. During the June 1993 sampling period, the DEM found water
quality bioclassifications of Good, Good-Fair, and Good-Fair for the Above-ABTCO,
Below-ABTCO, and Wilkesboro-Reference sites, respectively. The DEM also found several
intolerant EPT species at the Above-ABTCO, but not at the Below-ABTCO site. This study was
initiated to examine EPT taxa richness and abundances at these sites following initiation of a plan
in 1993 to improve effluent discharge which decreased solids and B.O.D. by 1996 (Table 1).
METHODOLOGY
Station Locations
The reach of the Yadkin River studied were located near the towns of Roaring River and
North Wilksboro,North Carolina. These sites have been previously sampled by the N.C. DEM.
Above-ABTCO -Located in the Yadkin River from approximately 200 to 250 feet above
the waste effluent pipe of ABTCO draining to the Yadkin River.
Below-ABTCO -Located in the Yadkin River approximately 150 to 300 feet below the
waste effluent pipe of ABTCO draining to the Yadkin River. The water depth was deep (>7 feet)
and the substrate dominated by sand and silt for collections on the same side as the ABTCO
facility. A well defined riffle zone was located approximately 150 feet below the waste effluent
pipe in the Yadkin River. The water depth was too great to wade to a riffle zone from the
ABTCO side of the river. This riffle zone was accessed along the Claude Shew Jr. Farm property
on the opposite shore from the ABTCO facility.
Wilkesboro-Reference-Located across from the USGS water level gauge site in North
Wilksboro. This site is located on the river above where the two Wilksboro wastewater treatment
plants (WWTP) discharge into the river.
Field Sampling
Field sampling dates for benthic macroinvertebrates were June 24-26, July 1 and 16, 1998.
EPT were examined because, in general, the majority of the taxa(species) in these three orders
are pollution sensitive. At each sampling site, water temperature and pH were assessed. Water

d
0
temperatures were assayed with a pocket field thermometer. The pH was measured with a Hanna
pH field meter.
Sampling methodology followed Standard Operating Procedures Biological Monitoring
(1992) for benthic macroinvertebrates. Each site was sampled by the EPT Method which
consisted of one(1) kick net sample, one(1) sweep-net sample, one (1) leaf-pack sample, and
visual collections. Benthic macroinvertebrates(Ephemeroptera, Plecoptera, Trichoptera)were
collected and preserved with 95% ethanol in the field.
Specific Samplin Techniques
echniques
Kick Net-A kick net(500 µ mesh) reinforced with muslin attached to wooden poles was
used to sample in current areas. The net was placed on the stream bed and a 1-2 m area upstream
was disturbed to dislodge debris and organisms in the sample area. Organisms on the kick screen
were picked off the kick net and washed down into a sieve bucket(500 µ mesh) while debris was
removed. One(1) sample was taken with the kick net.
Sweep Net-A sweep net was used to sample one(1) area along the creek banks.
Leaf-Pack Sample- One(1) leaf pack sample was collected from rocks and snags in fast
current areas and washed down into a sieve bucket.
Visual Search-Visual inspection of large rocks and logs occurred at each site.
Habitat assessments were conducted at each site. Assessments were based on twelve (12)
categories of the creek and surrounding habitat, and scored based on Optimal, Sub-Optimal,
Marginal, and Poor Categories. The 12 assessment categories were summed and an overall
habitat assessment scored for the station. Higher scores indicated better habitat structure.
Habitat assessments were calculated and scored independently of criteria for assigning water
quality ratings based on benthic macroinvertebrate data.
Laboratory Identification
EPT were identified to the lowest possible taxonomic level using a Ward's Advanced
Stereomicroscope. General reference guides were used as well as Aquatic Insects and
Oligochaetes of North and South Carolina(1982) as a primary resource for EPT identifications.
Data Analysis
Data were analyzed to calculate species richness according to N.C. Department of
Environment, Health and Natural Resources(NCDEHNR) criteria. EPT Taxa Richness and EPT
Abundances were assessed at the sampling stations for each sampling date. The EPT Taxa
Richness equaled the sum of EPT taxa. The EPT Abundances were obtained by summing all EPT
individuals tabulated as Rare(1-2), Common(3-9) or Abundant (10).

Several metrics can be used to detect water quality differences along a stretch of a creek
or river. EPT taxa richness is used to access differences in water quality between sites. For the
Mountain providence of North Carolina, the NCDEHNR criteria for EPT taxa richness
corresponds to the following bioclassifications: Excellent>35; Good 28-35; Good-Fair 19-27;
Fair 11-18;Poor 0-10. The bioclassification rating primarily reflects the influence of chemical
pollutants, but can be biased by creek habitat structure. Water quality ratings or bioclassification
ratings of Excellent, Good, Good-Fair, Fair and Poor for EPT samples are assigned to streams
based on this metric calculation. Results of the study are presented in tabular form.
RESULTS
Physical Characteristics
There were substrate differences between the three sites sampled in the Yadkin River
(Table 2). More rubble and gravel.substrate was found at the Above-ABTCO and
Wilkesboro-Reference sites. Substrate size and composition was more varied at the
Above-ABTCO site. Sand and silt comprised forty(40)percent of the substrate at
Below-ABTCO site. Also, the Above-ABTCO site received a higher habitat score than the other
sites. The higher score was due primarily to a greater riffle/pool/run/bend ratio, substrate
complexity and the lack of islands or bar formations at the Above-ABTCO site. River weed
(Podostemum)was abundant at the Above-ABTCO and Wilkesboro-Reference sites and common
at the Below-ABTCO site.
Benthic Macroinvertebrate Survey
EPT Taxa Richness and Abundances were greatest at the Above-ABTCO site(Table 3).
EPT sampling gave a Good bioclassification rating at the Above-ABTCO site. A Good-Fair
bioclassification rating was found for the Below-ABTCO and Wilkesboro-Reference sites. The
EPT Taxa Richness was 24 and 25 at the Below-ABTCO and the Wilkesboro-Reference sites,
respectively. The EPT Abundance was 104 at the Below-ABTCO and 96 at the
Wilkesboro-Reference site. These findings show similarity of bioclassification of benthic
macroinvertebrates found in the water at the Below-ABTCO and at the Wilksboro-Reference site.
Tolerance values for individual benthic macroinvertebrate species vary from 0 to 10, with
the higher numbers indicating more tolerant species of polluted conditions. Many EPT species
collected below the effluent discharge of ABTCO were tolerant species (Table 4). However, one
intolerant stonefly species,Pteronarcys dorsata(NCBI= 1.7)was more common at the
Below-ABTCO site(3 collected)than at either Above-ABTCO (1 collected) or
Wilkesboro-Reference(none collected) sites. This species has not been previously observed at
the Below-ABTCO site.
DISCUSSION
Substrate differences, in part, may explain the distribution of benthic macroinvertebrates
along the reach of the Yadkin River studied. In general, the larger the stone habitat, and hence

the more complex the substrate, the more diverse is the benthic macroinvertebrates fauna. Sand is
a relatively poor habitat and causes lower benthic macroinvertebrate species diversity. Both sites
located at Above-ABTCO and Wilksboro-Reference scored higher habitat scores, in part, because
they had more rubble and gravel substrate than the Below-ABTCO site. A poorer habitat score at
the Below-ABTCO were due, in part, to the dominance of sand and silt substrate. Also, river
weed was abundant and harbored many EPT species collected from boulders examined at the
Above-ABTCO and Wilksboro-Reference sites. River weed was common at the Below-ABTCO
site. Nevertheless, EPT taxa richness and EPT abundances were similar at the Below-ABTCO
and Wilksboro-Reference sites. This suggests that the habitat is superior for colonization of
benthic macroinvertebrates at the Above-ABTCO site than at the remaining sites.
Another factor possibly influencing the distribution of the EPT species found at the
Below-ABTCO site could be historical discharges at the plant. Beginning in 1996, ABTCO
began decreasing waste loads to the Yadkin River(Table 1). The N.C. DEM reported in June
1993 at the Below-ABTCO site: "the presence of a white fungal matter on substrate surfaces".
Also, they reported a lack of Podostemum (river weed) at the Below-ABTCO site. No white
fungal matter was observed in the river during the 1998 surveys at the Below-ABTCO site.
ABTCO has significantly changed the operation of the WWTP, resulting in the dramatic decrease
in solids discharge to the river. This change in operation has decreased the amount of filamentous
bacteria(fungi)found in the WWTP as well as the effluent. These changes may have resulted in
the lack of observation of the fungal matter during this survey. Also, I found Podostemum
common at the Below-ABTCO site. The data implies we are now seeing the recovery of the
Yadkin River near the plant discharge illuminated by the establishment of Podostemum, absence
of fungal matter, and presence of more intolerant species (i.e.Pteronarcys dorsata) at the
Below-ABTCO site. It will require additional monitoring upon permit renewal of the benthic
macroinvertebrate community to establish if this trend continues.
FINDINGS
1). The Above-ABTCO site received the best habitat score based primarily to a greater
riffle/pool/run/bend ratio, substrate complexity and the lack of islands or bar formations at the
site.
2). A"white fungal matter" previously observed at the Below-ABTCO site was absent
and Podostemum (river weed)was common at the site.
3). EPT taxa richness suggested that water quality was the best at the Above-ABTCO site
and the same at the Wilksboro-Reference and Below-ABTCO sites.
4). Bioclassifications were Good for the Above-ABTCO site, and Good-Fair for the
Wilksboro-Reference and Below-ABTCO sites.
RECOMMENDATIONS
1)EPT richness and abundance studies should be repeated upon permit renewal to
monitor the benthic macroinvertebrate species diversity in the Yadkin River near the ABTCO
discharge.

2) Sampling of the Yadkin River should be limited to summer low-flow periods to provide
greater access to riffle areas, especially at the Below-ABTCO site.

Sludge Management Plan
ABTco Industrial Wastewater Sludge
Overview: ABTco Industrial Wastewater Sludge is managed and disposed of in
compliance with our Land Application of Wastewater Residuals Permit No. WQ0000461
as issued by the State of North Carolina, DENR, Non-Discharge Section.
Nature of Sludge: The sludge produced at ABTco is a blend of primary fiber and waste
activated sludge. The primary sludge consists of ground wood fiber, dirt, "pin" chips and
other heavy materials which settle in the primary clarifier. Primary sludge accounts for
one quarter of the total sludge on a weight basis. The secondary sludge consists of
activated sludge from our aeration basin. This sludge is thickened in a dissolved air
flotation unit and conditioned by a rotary thickener before being dewatered by the belt
press. Secondary sludge accounts for the remaining two thirds of our sludge. Polymers
are used in the dewatering process and the final product is a sticky putty like material.
Current Production:
Current production is 20 - 25 tons per day with a maximum output of 30 tons per day on a
dry weight basis. Density of the sludge is identical to water;therefore production is 641 to
801 cubic feet per day average with a maximum of 962 cubic feet of material.
The sludge currently produced is 15% solids/85% water.
Program Description:
This program has been in existence since 1979 and is of on-going operation to provide soil
amendment for cropland and agricultural utilization of digested sludge' from the ABTco
wastewater treatment system. The following program, method of operation and
management practices represent the organization and execution of the program in order to
utilize the agriculturally important nutrients of digested sludge while minimizing any
potential adverse effect on the environment. All data, documentation, and plans have
received critical input from country, state, company, and private consulting firms which
represent accepted management and practices. A sludge monitoring program will
continue throughout the duration of the entire program with a grab sample analyzed
regularly to determine nitrogen loading rates, an annual sludge analysis and an annual
sludge TCLP in compliance with our land application permit
' Assume application of flyash from the plant wood-fired boilers will conform to the
methodologies stated for sludge.

METHOD OF OPERATION
I. Land:
A. Land identified to receive sludge applications will be recorded on
topographical map extracts with directions to each location and will be
accompanied by a written request from the farmer(lessee or owner) for
sludge application.
B. Parcels of land to receive sludge application will be identified by a
numbering system on a daily basis by the Operator in Responsible Charge
to ensure the sludge is only applied on approved or permittee land.
II. Sludge will be conveyed from the sludge dewatering press and transported in a
spreader and/or an"Ag-Gator"truck. No sludge will be spilled on the highways.
The sludge will then be spread upon the designated land. Only the surface
application method of sludge spreading will be used.
Land application will proceed in accordance with the following specifications:
A. Adequate provisions shall be taken by the landowner to prevent wind
erosion and surface runoff from conveying pollutants from the sludge
application area onto the adjacent property and into surface waters.
B. Sludge shall not be applied in inclement weather or until 24 hours
following rainfall event of 1/2 inch or greater in 24 hours.
C. No type of sludge other than that from ABTco Waste Water Treatment
Plant shall be placed on the disposal site.
D. A 100 ft. buffer zone shall be maintained between the landowner's
property line, structures, drinking water well(s) and major waterways. In
addition, a buffer of 25 feet will be maintained from any major ditch.
E. The site shall be adequately limed by the landowner to maintain a pH of
6.0.
F. No root or leaf crops for human consumption shall be grown on these
sites.

L
A '
G. Maximum slope for surface application shall be 10 up to 18%if ground
conditions will allow2 .
H. Sludge shall be evenly applied over the land.
I. Annual soil analysis, triannual groundwater monitoring, and annual
reports of sludge macronutient and micronutrient applications shall be
forwarded to the appropriate authorities.
J. Application rates shall not exceed crop specific rates as specified in the
Land Application Permit.
SLUDGE ANALYSIS
A. Sludge to be applied is generated from the process water of a hardboard
siding plant. The wastewater is treated by a primary clarification followed
by an activated sludge process and secondary clarification. The final
product is an equal ratio blend of solids(wood fiber)with biological solids
from the treatment system. Dewatering is accomplished using a dissolved
air flotation unit followed by a rotary thickening and a belt press. The
cake generated will average 15 to 25% solids and is structurally stable. In
addition, the odor of fresh sludge is not offensive but has a"musty"
aroma.
B. A grab sample will be obtained regularly and analyzed for TKN
(Total Kjeldahl Nitrogen). This analysis will form the base for the
application rates.
C. Calculations of macronutrient (base on TKN test) and micronutrient
(based on an annual sludge analysis) loading rates will be performed by a
qualified employee of ABTco
RECORDS
Records shall be maintained on a daily basis for each section and/or plot of land receiving
sludge by the ABTco operator in responsible charge. Appropriate data,and information
will be recorded and not limited to the following:
A. Pounds applied and Date(Annual)
B. Method of Application
C. Groundwater Monitoring Data
z Special Conditions: Maintenance of good vegetative cover and application of solid or
semi-solid sludge with equipment that does not excessively damage the vegetation. Also,
extensive erosion control practices shall be implemented by the landowner.

,Y
D. Amount of Nutrients Applied(Annual)
E. Amount of Heavy Metals Applied (Annual)
F. Soils Monitoring Data
REPORTS
All necessary reports concerning sludge analysis, surface water monitoring, groundwater
analysis, soil analysis, and/or others as deemed necessary by the permitting agency will be
submitted as required by ABTco.
EMERGENCY SITUATIONS
An emergency spill control and clean-up plan shall be developed and implemented, if
.required. Any large spills that occur will be reported to the permitting agency and handled
as any other spill occurrence. Any spills deemed a nuisance at the plant site or in transit to
the disposal site or at the disposal site are the responsibility of the permittee and will be
cleaned up immediately.
PROGRAM MANAGEMENT
The permittee has the complete responsibility of the Sludge Land Application Program.
The Operator in Responsible Charge has the responsibility of overall supervision and
organization to ensure the sludge land application is conducted in accordance with the
program plan and all applicable permits.
A. Availability of Personnel: The ABTco Wastewater Treatment Plant
Leader will be the responsible person to calculate the field loading rates.
B. Equipment: A conventional farm spreader truck will be utilized to haul
and spread sludge on land accessible only by use of publicly owned roads.
The bed of the truck will be sufficiently water tight so as to not leak sludge
on public roads. Land which is adjacent to ABTco property, and therefore
accessible by permitted land, will be spread upon using the"Ag-Gator"
land spreader.
C. Anal, ical Capabilities: All analysis will be conducted by a state approved
laboratory in accordance with the Standard Methods procedure. The
sludge being applied will be analyzed for all constituents required by the
Land Application Permit.
D. Loadin Rates: The loading rates will be based upon recognized standard
depending upon the crop nitrogen requirements with special attention
given to heavy metal loading as dictated by published guidelines based on
Cation Exchange Capacity(CEC) of the soil.

System Management
Management of land application systems includes management of the soil, crop, method
application, and field or site management. The management of the land application will
not be limited to the following major areas of concern; however, they may be implemented
as required.
A. Applicator System: An"Ag-Gator" sludge applicator truck and
conventional spreader truck shall be utilized for surface application. In-this
program, site loading will be based upon analysis which equates to pounds
of plant available nitrogen per acre. The applicator will ensure even
distribution over an application site. The equipment will be inspected
prior to each use and shall be properly maintained to insure it is in proper
operating condition
B. Field Site Management: Although the field or site management is the
responsibility of the individual landowner involved, periodic and
systematic inspections of the sites will be conducted by ABTco to ensure
the site conform to all specifications of the issued permit and the special
conditions that pertain to the particular site. The inspection will include,
but not be limited to the following:
1. Crop Harvesting
2. Diking (If Required)
3: Berms (If Required)
4. Terraces (If Required)
5. Maintenance of pH at greater than 6.0.
6. Annual soil analysis with recommendations for additional supplements
for optimum crop growth.
7. Control of any diseases or pests.
When and where needed, local agricultural and soil extension agencies will provide
necessary expertise.
C. In-Plant Malfunctions and Errors: In-Plant malfunctions and errors are not
anticipated as having any effect upon the land application program.
D. Natural Phenomena: Natural phenomena include severe freezing,
extended rainstorms and other uncontrollable problems such as vandalism.
1. Dewatering sludge will not be applied to any land if rain is imminent.
2. Dewatering sludge will not be applied to any land for a minimum of 24
hours after a 1/2 inch rainfall event.

v '
t)
' 3. The land to receive the dewatering sludge is privately owned property.
The sites are fenced and posted; therefore, access is restricted.
E. Landowner Responsibilities: The landowners responsibilities when
spreading and transporting the sludge from ABTco are:
1. Safety and public health responsibilities should-be assumed the same as
those outlined by the ABTco Sludge Disposal Permit. ABTco will be
the responsible party in situations where sludge has caused such a
problem. ABTco reserves the right to revoke sludge spreading
privileges in case of intentional safety and/or public health violations
by the landowner.
2. The landowner will not be responsible for handling citizen complaints
or other public relations concerning sludge. All such issues should be
referred to ABTco Environmental Engineer.
3. It is the specific responsibility of the landowner to report accidents,
spills, and other violations involving ABTco sludge directly to the
Environmental Engineer.
4. Record keeping responsibilities of the landowner will consist of each
truckload weight and where the load was applied by site number.
Failure to disclose land application records by the landowner
constitutes grounds for immediate termination of sludge spreading
activities upon all land possessed by

NPDES Permit Modification for Instream Sampling
NPDES Permit NC0005266
Wilkes County
Dear Permittee:
As a participant in the coordinated instream monitoring efforts within the Yadkin-Pee Dee River basin,
your facility and the North Carolina Department of Environment and Natural Resources (DENR) have
entered into an agreement that provides both parties with an effective environmental monitoring tool. By
this letter, the DENR is waiving the instream monitoring requirements as specified within your individual
NPDES permit beginning June 1, 1998. As specified in the Memorandum of Agreement (MOA) signed by
this agency and you (or your representative), the agreement identifies the stations, parametric coverage
and frequency of analysis required in order that the instream monitoring requirements be waived for your
facility.
All other terms and conditions in the original permit remain unchanged and in full effect. These
modifications are issued pursuant to the requirements of North Carolina General Statute 143-215.1 and
the Memorandum of Agreement between North Carolina and the U.S. Environmental Protection Agency
dated December 6, 1983. Should your membership in the agreement be terminated, the instream
monitoring requirements specified in your permit will be reinstated. You shall notify the Division
immediately upon termination of membership.
I would like to express my appreciation for the cooperation and participation of all participants in this
innovative approach to environmental monitoring. It is expected that the results of the agreement will
effectively contribute to our understanding of the Yadkin-Pee Dee River basin environment. We have
designated Cathy Tyndall as our primary contact for issues related to the MOA. She can be reached at
[phone].
We also look forward to the advances that this cooperative agreement will provide in our management of
the Yadkin-Pee Dee River basin and ask that you feel free to contact us should any questions arise
regarding the monitoring efforts or interpretations of the information collected. We will be maintaining
our own series of monitoring stations in the basin which, when added to the information collected by this
agreement, will greatly expand our knowledge of this environmental system. We thank you again for your
participation and look forward to a successful monitoring effort.
Sincerely,
i
Preston Howard,
