SUPPLEMENT TO EFFLUENT LIMITATIONS
AND MONITORING REQUIREMENTS
SPECIAL CONDITIONS
A (2). CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to Ceriodaphnia
dubia at an effluent concentration of 0.96 %.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in the "North Carolina
Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent versions or "North Carolina Phase
11 Chronic Whole Effluent Toxicity Test Procedure' (Revised -February 1998) or subsequent versions. The tests will be
performed during the months of March, June, September, and December. Effluent sampling for this testing shall be
performed at the NPDES permitted final effluent discharge below all treatment processes.
If the test procedure performed as the first test of any single quarter results in a failure or ChV below the permit limit, then
multiple -concentration testing shall be performed at a minimum, in each of the two following months as described in "North
Carolina Phase lI Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions.
The chronic value for multiple concentration tests will be determined using the geometric mean of the highest concentration
having no detectable impairment of reproduction or survival and the lowest concentration that does have a detectable
impairment of reproduction or survival. The definition of "detectable impairment," collection methods, exposure regimes,
and further statistical methods are specified in the "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure"
(Revised -February 1998) or subsequent versions. .
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge Monitoring Form
(MR-1) for the months in which tests were performed, using the parameter code TGP3B for the pass/fail results and THP3B
for the Chronic Value. Additionally, DWQ Form AT-3 (original) is to be sent to the following address:
Attention: North Carolina Division of Water Quality
Environmental Sciences Section
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section no later than 30 days after the
end of the reporting period for which the report is madeJest data shall be complete, accurate, include all supporting
chemical/physical measurements and all concentration/response data, and be certified by laboratory supervisor and ORC or
approved designate signature. Total residual chlorine of the effluent toxicity sample must be measured and reported if
chlorine is employed for disinfection of the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity monitoring is required, the permittee
will complete the information located at the top of the aquatic toxicity (AT) test form indicating the facility name, permit
number, pipe number, county, and the month/year of the report with the notation of "No Flow" in the comment area of the
form. The report shall be submitted to the Environmental Sciences Branch at the address cited above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required, monitoring will be required
during the following month.
Should any test data from this monitoring requirement or tests performed by the North Carolina Division of Water Quality
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,
minimum control organism reproduction, and appropriate environmental controls, shall constitute an invalid test and will
require immediate follow-up testing to be completed no later than the last day of the month following the month of the initial
monitoring.

1.0 Proposed Chafes Incorporated Into Permit Renewal
• Add TRC limit
• Remove monitoring for cadmium, cyanide, arsenic, copper, fluoride, lead, zinc, chlorides,
and barium.
• Remove the nickel limit and reduce monitoring to monthly.
• Update effluent limit to reflect recent production data
• Correct stream class from WS-IV CA to WS-IV B CA.
• Correct facility class to class III. No changes need to be made to the permit; monitoring
requirements were based on the correct class.
2.0 Summar
Huffman Finishing, Inc. is a textile plant that manufactures hosiery and has requested renewal of
their existing NPDES permit. Applicable effluent guidelines are 40 CPR 410.52 (Subpart E, Knit
Fabric). The facility has a design flow of 0.25 MGD and its wastewater is 95`Y<, textile dye and
bleach process and 5% domestic. The plant discharges into the Catawba River (Lake Hickory)
approximately 2.5 miles below Rhodhiss Dam. This segment of the Catawba River is a class WS-
IV B CA waterbody in CTB32 subbasin. Previous permits have the streamclass listed as WS-IV
CA. The outfall is approximately one mile downstream of the water supply intake for the City of
Hickory.
Development of Effluent Guidelines
Applicable effluent guidelines are listed in 40 CFR 410.52 Subpart E, Knit Fabric. Huffman
Finishing was able to provide three years of actual monthly production data, which was then
manipulated to yield yearly averages (in lbs/month). Those averages were: 448,285 lbs per
month in 2004, 400,143 lbs per month in 2003, and 462,193 lbs per month in 2002. Once the

NPDES Permit Fact Sheet - 12/ 14/05 Huffman Finishing
Page 2 NCO025135
highest average (462,193 lbs/month) was determined not to be an outlier (greater than 20% of
long term average), that value was used to calculate the federal effluent guidelines. Table 1
summarizes the proposed limit development based on the federal effluent guidelines

The prior permit also included a 5% allowance for sanitary wastewater with respect to BOD and
TSS, however these additions were minor. Those increases were not made for this renewal.
The phenol limit proposed by the effluent guidelines would be equivalent to a daily maximum
discharge of 1247 pg/L. This value is far above the 20 pg/L limit in the previous permit. It
appears that the basis for the limit was an agreement between DELI and DWQ Huffman
Finishing used to discharge to a UT to the Catawba River where the IWC was higher. The WQ
based phenol limit at that location was 20 µg/L. When the facility relocated, DEH requested that
the limit not be raised to 104 pg/L, which would be the WQ based limit at the current location.

There were no detections (out of 13 samples) for either cadmium or cyanide. The monitoring
requirements will be removed for these parameters.
Maximum predicted concentrations for arsenic, copper, fluoride, lead, zinc, chlorides, and
barium were all below the allowable concentrations. These parameters were monitored
quarterly in the previous permit. Monitoring requirements will be removed during this
renewal.
The maximum predicted concentration for nickel was 156.6 pg/L. The limit will be removed
from the permit and monitoring reduced to monthly.
The maximum predicted silver concentration was 145 pg/L. This is far above the allowable
6.0 jig/L. Since silver is an action level parameter, a limit will not be added. However
monitoring will be retained in the new permit.
It appears that in the past, antimony has been a parameter of concern for this facility. During
this renewal, however, out of the 29 samples taken over the data review period there were
only three detections. Since there is no NC water quality standard for antimony, an RPA was
done using the EPA criteria. Although the analysis showed a maximum predicted
concentration above the allowable concentration, it is important to note that all three actual
detections were below the calculated allowable concentration. In this case it appears that the
large number of non -detects was a contributing factor in yielding a high multiplication factor
(7.4). Based on this analysis, antimony will continue to be monitored quarterly in the permit.
WET Test Results
The facility has passed 18/18 WET tests performed since May 2001.

There is ususally a sentence in there saying "There shall be no discharge of floating
solids or visible foam in other than trace amounts". It should have been in there.
I'll add it.
As far as antimony, that was a tough one because the facility had 29 samples but only
3 detections. Furthermore, all of the detections were below the calculated allowable
concentration. I believe in this case the fact that there were so many non -detects
was a contributing factor in creating a very high multiplication factor (7.4). We
have used our judgement with RPAs in the past when conditions such as multiple
detection levels have been factors in creating the impression of 'variance'. I try
to always look at the data set to make sure non -detects aren't working against
someone and in this case I felt that they were. So thats why I decided not to add a
limit. I should put a more detailed explanation in the fact sheet.

thanks for sending the permit appl. just have a couple of comments.
1. This thought just occurred to me. Typically, most states add a
narrative statement to the effect of "the discharge shall not cause a
visible sheen on the receiving water". Does NC do something similar?
If so, I didn't see it in this permit.
2. re antimony, the fact sheet indicates that there is RP based on the
3 detects, but monitoring only is being required. I would like to
understand more of your basis for not requiring a limit when RP is
indicated Typically, NC likes to have 8-12 data pts to make an RP
decision and you have that amount of data here.

The WS-IV & B CA classification is the correct one for Lake Hickory. The B class is
not really implied with any other freshwater classification, so I think your idea
about updating your documents accordingly is a good one.
Marcia Lieber wrote:
Toya, I think you would need to update because B refers to swimming. I am
forwarding your question to the staff in the classification and standards unit.
They are more knowledgeable on this than I am. SCUnit-- Can you help Toya, Thanks,

Hi Marcia,
I have a discharger into Lake Hickory, the CTB32 subbasin. The stream class
from the old wasteload allocations and NPDES permits is listed as WS-IV CA.
But in the current basin plan its listed as WS-IV B CA. Should I update the
permit and fact sheet with this classification? I wasn't sure if the B class
was already implied within the WS-IV classification.
Thanks,
Toya

FORM: LARS 02/95 Page 2 of 18

V . PATHOGEN AND VECTOR ATTRACTION REDUCTION INFORMATION (attach additional pages for
additional sources of residuals):
1. In accordance with 40 CFR Pan 503, a residual can not be land. applied if it does not meet one of the following alternatives
for Class B pathogen reduction.
b1 Please specify a, bl, b2, b3, M, b5 or c from below (submit all lab analysis, test results and calculations):
a. at least seven residuals samples should be collected at the time of use and analyzed for Fecal colifortns during each
monitoring period. The geometric mean of the densities of these samples will be calculated and should be less than
2,000,000 most probable number per gram of total dry solids, or less than 2,000.000 Colony Forming Units per gram
of total dry solids.
b. the residuals must be treated by one of the following "Process to Significandy Reduce Pathogens" (PSRP).
1. Aerobic Digestion - residuals are agitated with air or oxygen to maintain aerobic conditions for a spec mean cell
residence time and temperature between 40 days at 200 C and 60 days at 150 C.
2. Air Dryine - residuals are dried on sand beds or on paved or unpaved basins for a minimum of three months.
During two of the three months, the ambient average daily temperature is above 00 C.
3. Anaerobic Digestion - residuals are treated in the absence of air for a specific mean cell residence time and
temperature between 15 days at 350 C to 550 C and 60 days at 200 C.
4. Composiing - using either the within -vessel, static aerated pile, or windrow composting methods, the temperature
of the residuals are raised to 400 C or higher for five days. For four hours during the five days, the temperature in
the compost pile exceeds 550 C.
5. Lime Stabilization - sufficient lime is added to the residuals to raise the pH of the residuals to 12 aher two hours
of contact.
c. The residuals shall be treated by a process that is equivalent to a "Process to Significantly Reduce Pathogens" (PSRP),
as determined by the permitting authority, based on an evaluation of the recommendations provided by the Pathogen
Equivalency Comm tree.
2. In addition, when residuals are being land applied, at least one of the following vector attraction reduction requirements (a,
b, c, d, e, f, g, h, i, or j) described below must be met.
a Specify the letter(s) of the vector attraction reduction requirement that have been met (submit lab results, test
results and calculations). Any variation of the below must be described in full detail and attached.
a. Aerobic or Anaerobic Div stion - The mass of volatile solids are reduced by at least 38%. Volatile solids reduction is
measured between the residuals, prior to stabilization, and the residuals ready for use or disposal. This criterion should
be readily met by properly designed and operated anaerobic digestors, but not as readily met by aerobic digestors.
Treatment facilities with aerobic digestors may need to meet the vector attraction reduction requirement through 18c or
18d.
b. Anaerobic Digestion - If 38% volatile solids reduction cannot be achieved, vector attraction reduction can be
demonstrated by further digesting a portion of the previously digested residuals in a bench scale unit for an additional
40 days at 300 C to 370 C. If, at the end of the 40 days, the volatile solids are reduced by less than 17%, vector
att acdon reduction is achieved.
c. Aerobic DiP c ion - If 38% volatile solids reduction cannot be achieved vector attraction reduction can be demonstrated
by further digesting a portion of the previously digested residuals that have a solids content of 2% or less in a bench
scale unit for an additional 30 days at 201 C. If, at the end of the 30 days, the volatile solids are reduced by less than
1517o, vector attraction reduction is achieved.
d Aerobic Digestion - The specific oxygen uptake rate (SOUR) shall be equal to or less than 1.5 milligrams of oxygen
per hour per gram of total dry solids at 200 C.
e. Aerobic Processes - The temperature of the residuals for at least 14 days shall be greater than 400 C. During this time,
the average temperature shall be greater than 450 C.
f. Alkaline 4 abili ation - The pH of the residuals is raised to 12 or higher by alkali addition and, without the addition of
more alkali, remains at 12 or higher for 2 hours and then at 11.5 or higher for an additional 22 hours.
