CHRONIC TOXICITY MONITORING (QRTRLY)
The permittee shall conduct chronic toxicity tests using test procedures outlined in:
1.) The North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina Chronic
Bioassay Procedure - Revised *September 1989) or subsequent versions.
The effluent concentration defined as treatment two in the North Carolina procedure document is
d"f %. The permit holder shall perform quarter1v monitoring using this procedure to establish
compliance with the permit condition. The first test will be performed within thirty days from the
effective date of this permit during the months of vc[ �Afr) 4IP'
Effluent sampling for this testing shall be performed at the NPDES permitted final effluent
discharge below all treatment processes.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR-1) for the month in which it was performed, using the parameter
code TGP3B. Additionally, DEM Form AT-1 (original) is to be sent to the following address:
Attention: Environmental Sciences Branch
North Carolina Division of
Environmental Management
4401 Reedy Creek Rd.
Raleigh, N.C. 27607
Test data shall be complete and accurate and include all supporting chemical/physical measurements
performed in association with the toxicity tests, as well as all dose/response data. Total residual
chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for
disinfection of the waste stream.
Should any test data from this monitoring requirement or tests performed by the North Carolina
Division of Environmental Management indicate potential impacts to the receiving stream, this
permit may be re -opened and modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum
control organism survival and appropriate environmental controls, shall constitute an invalid test
and will require immediate retesting(within 30 days of initial monitoring event). Failure to submit
suitable test results will constitute noncompliance with monitoring requirements.

ACUTE TOXICITY PERMIT LIMIT (QRTRLY)
The permittee shall conduct acute toxicity tests on a quarterry basis using protocols defined as definitive in E.P.A.
Document 600/4-85/013 entitled "The Acute Toxicity of Effluents to Freshwater and Marine Organisms." The
monitoring shall be performed as a Daphni4 pulex or Ceriodaphni4 48 hour static test, using effluent collected as a
24 hour composite. The LC50 of this effluent using the previously stated methodology may at no time in any
toxicity test be less than 90 %. Effluent samples for self -monitoring purposes must be obtained during
representative effluent discharge below all waste treatment. The first test will bp performed after thirty days from
the effective date of this permit during the months of SGP Dec. Aroz fa
The parameter code for this test if using paphni4 pulex is TAA3D. The parameter code for this test if using
Cer iodaphni4 is TAA3B. All toxicity testing results required as part of this permit condition will be entered on the
Effluent Discharge Monitoring Form (MR-1) for the month in which it was performed, using the appropriate
parameter code. Additionally, DEM Form AT-1 (original) is to be sent to the following address:
Attention: Environmental Sciences Branch
North Carolina Division of
Environmental Management
4401 Reedy Creek Road
Raleigh, N.C. 27607
Test data shall be complete and accurate and include all supporting chemical/physical measurements performed in
association with the toxicity tests, as well as all dose/response data. Total residual chlorine of the effluent toxicity
sample must be measured and reported if chlorine is employed for disinfection of the waste stream.
Should any single quarterly monitoring indicate a failure to meet specified limits, then monthly monitoring will
begin immediately until such time that a single test is passed. Upon passing, this monthly test requirement will
revert to quarterly in the months specified above.
Should any test data from either these monitoring requirements or tests performed by the North Carolina Division
of Environmental Management indicate potential impacts to the receiving stream, this permit may be re -opened and
modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control organism
survival and appropriate environmental controls, shall constitute an invalid test and will require immediate
retesting(within 30 days of initial -monitoring event). Failure to submit suitable test results will constitute
noncompliance with monitoring requirements.

ACUTE TOXICITY TESTING REQUIREMENT (QRTRLY)
Daphnid 48 hr - LC50
The permittee shall conduct acute toxicity tests on a quarterly basis using protocols defined as
definitive in E.P.A. Document 600/4-85/013 entitled "The Acute Toxicity of Effluents to
Freshwater and Marine Organisms". The monitoring shall be performed as a Daphnia pulex or
Ceriodaphnia 48 hour static test, using effluent collected as a 24 hour composite. The LC50 of this
effluent using the previously stated methodology may at no time in any two consecutive toxicity
tests be less than TO _%. Effluent samples for self -monitoring purposes must be obtained during
representative effluent discharge below all waste treatment. The first test will be performed after
thirty days from issuance of this permit during the months of Vig aJN Sr? PE`c_
The parameter.code for this test if using Daphnia pulex is TAA3D. The parameter code for this test
if using Ceriodaphnia is TAA3B. Alltoxicity testing results required as part of this permit
condition will be entered on the Effluent Discharge Monitoring Form (MR-1) for the month in
which it=was performed, usingthe appropriate parameter code. Additionally, DEM Form AT-1
(original) is to be sent to the following address:
Attention: Environmental Sciences Branch
North Carolina Division of
• Environmental Management
P.O. Box 27687
Raleigh, N.C. 27611
Test data shall be complete and accurate and include all supporting chemical/physical measurements
performed in association with the toxicity tests, as well as all dose/response data. Total residual
chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for
disinfection of the waste stream.
Should any single quarterly monitoring indicate a failure to meet specified limits, then
monthly
monitoring will begin immediately until such time that a single test is passed. Upon assi lg,this
monthly test requirement will revert to quarterly in the months specified above. p a,
Should any test data from either these monitoring requirements or tests performed by the North
Carolina Division of Environmental Management indicate potential impacts to the receiving stream,
this permit may be re -opened and modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum
control organism survival and appropriate environmental controls, shall constitute an invalid test
and will require immediate retesting(within 30 days of initial monitoring event). Failure to submit
suitable test results will constitute noncompliance with monitoring requirements.

We are in the process of setting up a schedule with Huffman
Finishing for compliance with their toxicity limits. Huffman Finishing
has plans to investigate the source of their toxicity through studies
proposed by Burlington Research on April 15, 1991. Even though the
proposed discharge point is the mouth of the tributary currently
discharged into, further investjgation also needs to be done on the
dispersion of pollutants in Lake Hickory in relation to the water
supply intakes for the towns of Hickory an6 Longview. Therefore the
ultimate discharge point may be different from the one currently being
investigated. Further comments will be made after results of theses
studies are received.

FROM: Harold Quidley j
RE: Lake Hickory Dye Study
RECEIVED
OCT 0 21991
TECNti1GNL SUPPORT BRANCH
On 91/09/15 a tracer dye study was performed on a 1.35 mile reach of Lake Hickory. The study was
conducted at the request of the EHNR Asheville Regional Office and was designed to determine time -
of -travel from the mouth of an unnamed trib (UT) to the Longview and Hickory municipal water intake
pipes. Huffman Finishing Company (NC0025135) currently discharges into the UT approximately 0.6
miles upstream from the confluence with Lake Hickory. Huffman Finishing Company has proposed
relocating their effluent outfall to the mouth of the UT in an effort to increase dilution to improve
compliance with NPDES toxicity limits.
The upper portions of Lake Hickory are characteristic of a riverine system, and flow in the study
area is directly affected by discharge from the Lake Rhodhiss Dam. The dam is operated by Duke
Power Company and is located at the headwaters of Lake Hickory 2.6 miles upstream from the mouth
of the UT. At the request of EHNR, discharge from the dam was stopped during the dye study to
provide consistent low flow conditions in the study area.
At 0900 on 91/09/15, six liters of Rhodamine WT dye was poured into Lake Hickory approximately 20
feet from the mouth of the UT. The UT is located on the north side of the lake and on the inside of a
large bend (see map). Initial dispersion of the dye cloud was slow because the main flow of the lake
moves along the outside (south side) of the bend opposite from the UT. Higher velocities on the outside
of a bend and slower shallower water on the inside of a bend is typical in riverine hydrology. As a
result of the hydraulics created by the bend, an eddy carried a portion of the dye approximately 1000
feet upstream along the bank before dispersion occurred. In addition, dense aquatic macrophyte growth
(elodea) along the north bank of the lake retained dye and also slowed dispersion. The slow initial
dispersion of the dye created a streaking affect that could be seen for the first 2000 feet downstream to
station D (see map).

The main body of dye from the mouth of the UT downstream to station D traveled along the north
side of the lake. Stations A,B,C and D were set at 500 foot intervals. The leading edge of the dye cloud
was observed at station A at 0945, station B at 1030, station C at 1145 and station D at 1305. Time -of -
travel for the leading edge of dye from the mouth of the UT to station D (2000 feet) was 4 hours and 5
minutes with an average velocity of 0.136 ft/sec.
At Station D streaking was no longer observed and the cloud began to move away from the north side
as it.traveled downstream. At 1330 dye was observed at station E with the main body of dye near the
center of the lake. At 1530 dye was observed at station F near the south side of the lake. At 1630 the
leading edge of the dye was no longer visually evident but was detected by fluorometer at station G
(Longview WTP intake). Time -of -travel for the leading edge of the dye from station D to station G,
(0.65 miles, 3432 feet) was 3 hours and 25 minutes with an average velocity of 0.279 ft/sec. Time -of -
travel for the leading edge of the dye from the UT to the Longview WTP intake (1.03 miles, 5432 feet)
was 7 hours and 30 minutes with an average velocity of 0.201 ft/sec.
At 1807 dye was detected at station H (Hickory WTP intake), 0.25 miles downstream from the
Longview WTP intake. Time -of -travel for the leading edge of the dye from the UT to the Hickory
WTP intake was 9 hours and 7 minutes with an average velocity of 0.206 ft/sec.
At 1900 dye was detected at station I,1.35 miles downstream from the UT. Total time -of -travel from
the UT to station I was 10 hours with an average velocity of 0.198 ft/sec.
Accompanying this memo is a map showing station transect locations and highest dye concentration
values measured for each station. If you have any questions or need additional information please let
us know.

Through: Larry Ausley
From: Matt Matthews
Subject: Permit Compliance Schedule
Huffman Finishing Company
NC0025135
Caldwell
5EP 0 3 1991
BRANCH
Data Assessment and Certification Group personnel have reviewed and evaluated the subject draft compliance schedule(attached)
which is to be placed in the facility's new permit. The substance and time frame of the activities appear appropriate to the
facility's circumstances. We are in agreement with Mooresville Regional Office personnel that sources of toxicity in the effluent
should be investigated and eliminated irrespective of the ultimate location of the discharge pipe.
This office recommends that a multiple concentration chronic Ceriodaphnia test be performed on a quarterly basis during the time in
which no toxicity limit is in effect. As to the facility's ultimate toxicity limit, it is recommended that a chronic limit of 84% be
assigned based on the existing discharge point's 7Q10 of 0.075 and the permitted flow of 0.25 MGD. Should the discharge point
be relocated to the proposed site on Lake Hickory, an acute limit of 96% would be appropriate based on an IWC of 0.96%. The
IWC is calculated from the permitted flow of 0.075 MGD and the 7Q10 of 40 cfs which is based on the minimum instantaneous
release from the Catawba River -Lake Rhodhiss dam. Appropriate recommendation forms are attached for both the "monitoring
only requirement" as well as application of a limit.
If any further information or clarification is required, please contact me or Larry Ausley at [phone].

SUBJECT: Huffman Finishing draft permit.
NPDES No. NC0025135
Caldwell County
The draft permit for Huffman Finishing contains limits for toxics including cadmium,
chromium, nickel, cyanide, mercury, selenium, arsenic, barium, antimony, chloride,
fluoride, and phenols. These limits are all based on water quality standards and should
remain in the final permit. The limits for nickel, barium, chloride, and phenols were based
on standards for WS classes. These limits are based on data provided by Huffman
Finishing. Huffman recently completed a plant upgrade to meet its existing limits which do
not include these toxics limits. In 1989, the facility was asked to address toxicity during
the upgrade since the facility was failing its whole effluent toxicity tests. Huffman has
also failed its toxicity tests of March and June 1990.
Huffman Finishing has mentioned a possible relocation to the Catawba River. The
discharge point would be directly to Lake Hickory, a water source for Hickory and _
Longview. The water supply intakes for these communities are approximately one mile
downstream of the unnamed tributary to which Huffman discharges. Toxics limits may still
be required with discharge to Lake Hickory to protect the water supply and to comply with
the basinwide management strategy for the Catawba River basin. Before committing to
relocation, Huffman Finishing should identify its sources of toxicity and consider a
pollutant minimization plan in order to meet its water quality limits. The facility should
contact Pollution Prevention Pays for more information.
/ or those parameters which were added to the permit under this renewal, i.e., cadmium,
nic 1, cyanide, mercury, selenium, arsenic, fluoride, barium, antimony, and chloride, an
Y m'Y Y
implementation schedule can be developed for compliance. The chlorides limit should be
changed to 298 mg/1 rather than 298 ug/l. The units for the fluoride limit are also incorrect,
the limit should be 2.1 mg/l. Since the phenols limit is for the protection of odor and taste
in the water supply, the limit may be changed to 8 ug/1 which will protect the water supply
in Lake Hickory.
Please let me know if you have any questions regarding these comments.

Dear Ms. Barona:

Reference is made to your August 15, 1990 letter concerning the subject draft permit.
The monitoring requirements for the effluent parameters set forth in the draft
permit are for a Class III facility. The subject facility, after upgrading and
expansion to 0.250 mgd, was classified by the NCDEM as a Class II facility. A copy
of the October 26, 1989 letter from Mr. John Campbell concerning classification of
the Huffman Finishing Company's Wastewater Treatment Facility is attached. Accord-
ingly, it is requested that monitoring requirements be reduced to Class II facility
requirements.
Also, it is noticed that chloride, flouride, and metals limits are included in the
draft permit. The wastewater treatment facility is not designed to comply with
these limits, and compliance with these limits will impose economic hardship on our
operation by increasing treatment costs and penalties for noncompliance. It should
be noted that recently we have made substantial capital improvements to our
wastewater treatment facility to comply with the discharge limitations provided by
your office earlier for our plant upgrading and expansion to 0.250 mgd. Accordingly,
it is requested that these limits on chloride, flouride, and metals be deleted from
the permit.
We would appreciate your considerations in this matter. Should you have any
question concerning this matter, please call me at [phone].
Sincerely,

CHRONIC TOXICITY TESTING REQUIREMENT (QRTRLY)
The effluent discharge shall at no time exhibit chronic toxicity in any two consecutive toxicity tests,
using test procedures outlined in:
1.) The North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina Chronic
Bioassay Procedure - Revised *June 1988) or subsequent versions.
The effluent concentration at which there may be no observable inhibition of reproduction or
significant mortality is 8'-i % (defined as treatment two in the North Carolina procedure
document). The permit holder shall perform quarterly monitoring using this procedure to establish
compliance with the permit condition. The first test will be performed after thirty days from
issuance of this permit during the months of ft14t ,lUN See,1�ez- . Effluent
sampling for this testing shall be performed at the NPDES permitted final effluent discharge below
all treatment processes.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR-1) for the month in which it was performed, using the parameter
code TGP3B. Additionally, DEM Form AT-1 (original) is to be sent to the following address:
Attention: Environmental Sciences Branch
North Carolina Division of
Environmental Management
P.O. Box 27687
Raleigh, N.C. 27611
Test data shall be complete and accurate and include all supporting chemical/physical measurements
performed in association with the toxicity tests, as well as all dose/response data. Total residual
chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for
disinfection of the waste stream.
Should any single quarterly monitoring indicate a failure to meet specified limits, then monthly
monitoring will begin immediately until such time that a single test is passed. Upon passing, this
monthly test requirement will revert to quarterly in the months specified above.
Should any test data from this monitoring requirement or tests performed by the North Carolina
Division of Environmental Management indicate potential impacts to the receivint stream, this
permit may be re -opened and modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum
control organism survival and appropriate environmental controls, shall constitute an invalid test
and will require immediate retesting(within 30 days of initial monitoring event). Failure to submit
suitable test results will constitute noncompliance with monitoring requirements.

DIVISION OF ENVIRONMENTAL MANAGEMENT

MEMORANDUM
TO:
FROM: Betsy Johnson
THROUGH:
Greg Thorpe
Carla Sanderson
Trevor Clements
SUBJECT: Water quality limit based on federal criteria.
Huffman Finishing Co., NPDES No. NC0025135
Caldwell County
Huffman Finishing Co. discharges 0.25 MGD into a tributary of Lake
Hickory; both are classified WS-III. The tributary flows 0.6 miles to
Lake Hickory. Analysis of the effluent from Huffman Finishing found
large amounts of Antimony. Since there is no state standard for this
metal, federal criteria will be used to generate water quality limits.
Antimony (non -carcinogen)
Federal Criteria = 14 ug/1 (human health/water & organisms)
7Q10 = 0.075 cfs
Allowable based on 7Q10 = 16.7 ug/1
Effluent = 170 ug/1
Since the pollutant concentration is greater than 1/10 of the
allowable, an effluent limit is needed. The effluent limit for
Antimony will be 17 ug/1.
Please review and comment on the application of the federal criteria
for Antimony by July 6, 1990.

Subject: Chlorine Toxicity
NPDES Permit No. NC0025135
Caldwell County
Dear Mr. Huffman:
Chlorine, a widely used wastewater disinfectant for the
treatment of coliform organisms, often remains instream in residual
amounts that may prove to be toxic under critical low stream flow
conditions. In the last decade, EPA assessed the potential adverse
effects of chlorine to the aquatic environment and has taken steps to
reduce the impacts through the development of federal criteria. In
1986, EPA recommended that all states have a chlorine standard by
their next triennial review of water quality standards.
In revising its water quality standards in 1989, North Carolina
developed an action level for chlorine of 17 ug/1 (freshwater classes
only). In addition, the fecal coliform limit was reduced from 1000
colonies/100 ml to 200 colonies/ 100 ml. Under a new DEM procedure,
dechlorination and chlorine limits are now recommended for all new or
expanding dischargers proposing the use of chlorine for effluent
disinfection. The Division is reviewing chlorine levels from all
existing dischargers as part of their NPDES permit renewal process.
Our records indicate that chlorine from your facility's effluent
discharge is considered toxic to the receiving stream under low flow
conditions, i.e., the amount of chlorine discharged causes a
violation of the instream action level for chlorine (17 ug/1) under
7Q10 conditions (the lowest average daily flow for seven (7)
consecutive days during a ten (10) year period). Action should be
taken to reduce the effluent concentration of chlorine to an
acceptable level. Based on your facility's instream waste
concentration of 84%, an acceptable level of chlorine in your
effluent is 20 ug/1 or 0.02 mg/l. If this level is not feasible, you
should consider dechlorination or alternate methods of disinfection
for your facility to ensure that both chlorine and bacterial limits
are met. In addition, if your facility plans to undertake any phase
of construction, dechlorination or alternate disinfection should be
included. However, please note that an authorization to construct
must be obtained from this Division prior to any alteration to your
treatment plant.

-2—
The Division is currently reviewing its water quality
regulations pertaining to chlorine. In the future, effluent limits
and/or dechlorination may be required of existing facility's with
chlorine problems. If the chlorine levels in your facility's
effluent remain unchanged, a chlorine limit or a whole effluent
toxicity testing requirement may be added to your permit limitations.
Please feel free to call Rex Gleason of the Division's Regional
Office at [phone], if you have any questions or comments
regarding this issue.
Sincerely,
