SUPPLEMENT OT EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS
SPECIAL CONDITIONS
A. (3.) 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 46%.
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 II 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 H 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 H 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
TBP3B for the Chronic Value. Additionally, DWQ Form AT-3 (original) is to be sent to the following address:
Attention: NC DENR DWQ / Environmental Sciences Section
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Branch no later than 30 days after
the end of the reporting period for which the report is made.
Test 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.

SUBJ: Draft NPDES Permit
Schneider Mills
Permit No. NCO034860
Dear Dr. Chemikov:
In accordance with the EPA/NCDENR MOA, we have completed review of the draft
permit referenced above and have no comments. We request that we be afforded an additional
review opportunity only if significant changes are made to the draft permit prior to issuance or if
significant comments objecting to the permit are received. Otherwise, please send us one copy of
the final permit when issued.

To: Marshall <[e-mail]>
Marshall,
I need to make a few corrections to the above referenced permit. Unfortunately, records
of the modification (December 9, 2002) to the permit were missing from our files and I
did not make appropriate changes when permit was drafted. Hopefully, you have the
December 9, 2002 letter in your files.
The following corrections have to be made for Outfall 002:
1) Measurement Frequency for flow has to be changed to Weekly, and Sample type has to
be changed to Instantaneous.
2) Sample Type for TSS and Iron has to be changed to Grab.
For Outfall 001 monitoring for Silver has to be discontinued. One of the conditions of
the previous permit was: " ... if silver is not detected after one year from the permit
effective date (4 additional data points), the Division will consider the permittee's
request to discontinue quarterly silver monitoring." DMR review indicated the silver
was not detected in the effluent since 06/11/02.
Pemittee also informed us that they are closing down Alexander Mills facility and will
be consolidating operation at Taylorsville Plant. As a result production will be
increased to 42,000 lb/day from 40,000 lb/day beginning mid -August. I propose to
recalculate their effluent limits based on new number. The difference should be
insignificant. The new permit will become effective September 1, 2005.
Please review proposed changes.
Thank you!

Dear Sir,
We have closed our plant at Alexander Mills and we are moving the equipment
and production to our Taylorsville Plant.
Moving the machinery will be complete in late July to mid August. Production
should be up by mid August to early September.
Expected production would be approximately 6000 lb. per day increase or 42,000
lb. a day total. These are forecasted at levels of last quarter orders.
Thank you for working with us during our restructuring.
Thank you,

Dear Mr. Chernikov,
[phone] Phone
[phone] Fax
In our last permit it was stated that if silver is not detected after one year from the J x
effective date, that the Division will consider discontinuing quarterly silver monitoring. �>
Silver has not been detected since our last permit was issued. We request this bet en V11
our new permit. Due to no detection since November 1, 2002 the effective date of our last J
permit <` y
We would like for you to consider taking phenols and total chromium off of our
new permit also. We noticed in this draft permit on the limitation page that Bod, Sulfide
and Phenol limits have been lowered due to the reduction in the production volume. We
would like for the limits to stay the same as they are now. Closing of our Alexander Mills
Plant and consolidate their loom and orders to the Taylorsville Plant will raise our
production at this plant. The machinery should be completed late July. We should expect
an increase of production shortly after that.
On the supplement to Permit Cover Sheet under #2 on this page for 002. It is
stated that the discharge is air conditioning condensate water treatment plant (WTP) filter
backwash, boiler blow down and storm water runoff. The only dischaz -e from 002 is
water treatment plant (WTP) filter backwash. Also on a 02 on the limitatt pnso�age
under flow measurement sample type it has recording it needs to be changed to
instantaneous. We have no flow recorder installed. -
?— llso under sample type for 002 we would like fob TSS and iron to stay Grab_ ti
sample instead of composite. We have always taken Grab samples for 002. We would
like for you to consider these changes to the draft permit. If you have any questions,
please call Darren Webb or Gary Elder at [phone].

PART III - OTHER PERTINENT INFORMATION
1. Is this facility being constructed with Construction Grant Funds or are any public monies
involved (municipals only)? Public monies were not used in the construction of this facility.
2. Special monitoring or limitations (including toxicity) requests: Schneider Mills has requested
that quarterly silver monitoring be removed from the permit. The justification provided by
Schneider Mills is that silver has not been detected during the term of the current permit. The
Fact Sheet prepared for the current permit indicated that silver could be removed as a parameter
if the permittee provided sufficient data (12 months or more) reflecting non -detects for silver.
Schneider Mills now has accumulated more than four years worth of data, and has requested (via
letter dated May 11, 2005) that silver monitoring be removed from the permit. This Office has
no objection to this request, and recommends monitoring for silver be removed.
Schneider Mills also requested in the May 11, 2005 letter that the monitoring and effluent limits
for Phenols and Total Chromium be removed from the permit. Schneider Mills did not include
justification for the removal of these parameters, however, effluent data indicates that they have
been at or near detection levels for the past few years. It is the MRO's understanding that the
effluent limitations for these parameters are based on guidelines contained in 40 CFR 410.43(a),
and it may not be possible to remove the testing for these parameters given that they are based on
Federal categorical guidelines. This Office defers comment to the NPDES Unit for a review and
decision on this matter.
3. Important SOC, JOC or Compliance Schedule dates (Please indicate): This facility is neither
under and SOC nor is one being considered at this time.
4. Alternative Analysis Evaluation:
Spray Irrigation: Inadequate area available to assimilate the amount of wastewater from this
facility.
Connection to Regional Sewer System: Sewer is not available in this area.
Subsurface: Inadequate area available to assimilate the amount of wastewater from this faility.
Other disposal options: None that we are aware.

PART IV - EVALUATION AND RECOMMENDATIONS
The permittee, Schneider Mills, Inc., has applied for permit renewal. Schneider Mills is
primarily engaged in the weaving of man-made fibers into cloth. Modifications to the permit
requested during this renewal are noted in Part III, No. 2 above. There have been no WWTP
modifications since the permit was last reissued.
The WWT facilities appear to be adequate to treat the wastewater to meet existing effluent limits.
Dutfall 001 is the discharge from the industrial and domestic wastewater treatment facilities, which
includes industrial process wastewater, air conditioning condensate, and boiler blowdown. Industrial
wastewater is generated by water jet looms and sizing operations. Wastewater from the filter
backwash serving Schneider Mill's water treatment plant is discharged through outfall 002.
Pending a final technical review by the NPDES Unit, it is recommended that the permit be
renewed.

INTRODUCTION
Schneider Mills, Inc. (also herein referred to as Schneider Mills or the permittee) requires a National
Pollutant Discharge Elimination System (NPDES) permit to dispose treated wastewater to the surface
waters of the state. The permittee's 5-year NPDES permit has expired and they have requested
renewal from the Division of Water Quality (the Division). This Fact Sheet summarizes background
information and rationale used by the Division's NPDES Unit to determine permit limits and
conditions. This document also contains references to information sources relevant to this permit
renewal (superscripted numbers in order of appearance, See References).
Facility Description. Schneider Mills is a synthetic textile weaving facility discharging process -
contact wastes and non -process wastes through two separate outfalls. hnfluent to the onsite
wastewater treatment plant (WWTP) includes waste from "water jet weavers" (roughly 85%) and
fiber coating or "sizing" waste (about 15 %). Sanitary sewer (-1,200 gallon per day) comprises only
0.03 % of the WWTP influent. The WWTP discharges through Outfall 001 with a permitted flow of
0.780 MGD. Non -contact wastewater (Outfall 002; flow not limited) includes air-conditioning
condensate, boiler blowdown, Water Treatment Plant (WTP) filter backwash, and stormwater.
Schneider Mills has been in business in North Carolina since 1951. At this location Division records
date from 1972.

PERMITTING APPROACH
Limits for parameters regulated under 40CFR 410 Subpart D have been recalculated to reflect new
production level. Based on data provide by the permittee, limit calculations assume 40,000 lbs/day as
the average production rate over three years (2001, 2002 and 2003). Parameters required under
40CFR are summarized in Table 2.

Further Consideration of Total Chromium. Technology based calculations for chromium
(40CFR) were compared to the acute and chronic NC State Standards (Chronic = 50 µg/L; Acute =
1022 µg/L — %Z FAV for freshwater) to evaluate which permit limits are more stringent, i.e. more
environmentally conservative.
Chronic Chromium -- Weekly Average Limit
Considering dilution (IWC 46 %): 50 UgIL 109 µg/L
0.46
compared to technology based: 2.0 lbs/day = 0.780 MGD (flow) x 8.34 x (y) mg/L
y = 0.307 mg/L or 307 µg/L
Therefore: because 109 µg/L is less than the technology -based limit of 307 µg/L, the more
environmentally conservative 109 µg/L will be implemented to protect against the
chronic affects of chromium as a Weekly Average.
Acute Chromium -- Daily Maximum Limit
Considering: 1,022 µg/L (freshwater %a FAV, intentionally not accounting for dilution)
Fact Sheet
Renewal -- NPDES NCO034860
Page 2

compared to Technology based : 8.0 lbs/day = 0.780 MGD (permitted flow) x 8.34 x (y) 1 mg/L
y-- 1.230 mg/L or 1,230 µg/L
Therefore: because the Y2 FAV of 1,022 µg/L is less than the technology based limit of 1,230
µg/L,1,022 µg/L is more environmentally conservative and will be implemented as a
Daily Maximum to protect against acute toxic affects.
Reasonable Potential Analysis
Reasonable potential analysis was conducted for: Cd, Cr, Ni, Pb, Ag and Zn. (see attached).
Toxicity Testing
Current Requirement: Quarterly Chronic Toxicity @ 46% MAR, JUN, SEP, DEC
Recommended Requirement: Quarterly Chronic Toxicity @ 46% MAR, JUN, SEP, DEC
The facility has been consistently passing its WET tests (see attached).
Compliance Summary
DMRs have been reviewed for the period January 2002 through March 2005. Facility has a good
compliance record. During the review period, the following NOVs (notices of violation) have been
issued: 01/08/04 — Sulfide; 07/15/03 — Sulfide.
A compliance evaluation inspection conducted on January 11, 2005 determined that the facility is in
compliance.
Instream Monitoring
Instream monitoring is required for Conductivity, Temperature, and Dissolved Oxygen.
Analysis of the instream monitoring data indicates that facility has insignificant negative
effect on the stream water quality (see attached).
Proposed Changes
• Monitoring Frequencies: TRC monitoring has been added to the outfall 002.
• Limits: Based on the application flow data, calculations were conducted in accordance with
federal guidelines. Based on the calculation results, limits were reduced for most parameters.
Calculated COD limit exceeded current limit, but since the permittee has been able to consistently
meet the current limit, the decision has been made to leave it unchanged. Similar decision has
been made regarding TSS limit. A daily maximum limit for ammonia nitrogen has been added to
the permit. A daily maximum value is five times the monthly average value.

CHANGES TO THE FINAL PERMIT
Following changes were made to the final permit:
Ourfall 002:
1) Measurement frequency for flow has been changed to Weekly, and Sample type was
changed to Instantaneous.
2) Sample type for TSS and Iron has been changed to Grab.
Changes for Outfall 002 were part of Permit Modification for previous permit. However,
NPDES file did not contain the record of this Modification and electronic version of the
Permit was outdated.
Permit supplement page:
The permittee has notified us that discharge from Outfall 002 consists of "Water
treatment plant filter backwash" only. The appropriate changes were made.
Outfall 001:
1) Monitoring for silver was discontinued. Previous permit stipulated that " ... if silver
is not detected after one year from the permit effective date (4 additional data points),
the Division will consider the permittee's request to discontinue quarterly silver
monitoring". Based on the DMRs review, silver monitoring was discontinued.
2) Permittee informed the Division that they are closing down Alexander Mills facility
and will be consolidating operation at Taylorsville Plant. As a result, production will
be increased to 42,000 lb/day. The limits were recalculated to reflect new production
level (COD and TSS were recalculated by adding 5% to the existing limit).

Subject: Draft NPDES Permit
Permit NC O034860
Schneider Mills W W1'P
Alexander County
Enclosed with this letter is a copy of the draft permit for your facility. Please review the draft very carefully
to ensure thorough understanding of the conditions and requirements it contains.
The draft permit contains the following significant changes from your current permit:
Limits for BOD, COD, TSS, Sulfide, Chromium and Phenols have been recalculated based on the
provided production data. Limits for COD, Chromium, and TSS remain unchanged, limits for BOD,
Sulfide and Phenols have been reduced due to the reduction in the production volume.
A daily maximum limit for ammonia nitrogen has been added to the permit. Due to the Federal Guideline
requirements the daily maximum value is five times the monthly average value.
A monthly monitoring for Total Residual Chlorine (MC) for Outfall 002 has been added to the permit.
State of North Carolina has recently adopted a TRC standard and this monitoring is necessary to evaluate
potential TRC discharges by Schneider Mills.
Please submit any comments to me no later than thirty days following your receipt of the draft Comments
should be sent to the address listed at the bottom of the previous page. If no adverse comments are received
from the public or from you, this permit will likely be issued in early July, with an effective date of August 1,
2005.
If you have any questions or comments concerning this draft permit, contact me at the telephone number or
e-mail address listed at the bottom of this page.

SUPPLEMENT OT EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS
SPECIAL CONDITIONS
A. (3.) 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 46%.
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 H 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 H 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 H 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
TBF3B for the Chronic Value. Additionally, DWQ Form AT-3 (original) is to be sent to the following address:
Attention: NC DENR DWQ / Environmental Sciences Section
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Branch no later than 30 days after
the end of the reporting period for which the report is made.
Test 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.

Annual Sulfide Problem

From: Joe Corporon <[e-mail]>�G

Hugh, you have been identified as "the man to ask."
I have an NPDES textile permittee in North Carolina with a problem
meeting sulfide limits (5.2 lbs/day mo ave.; 17lbs/day daily max.). This
problem apparently appears annually near Spring with fluctuating
temperatures, and has no identifiable correlation to production. They
operate, in part, a large pond with surface aeration. Our only thought
was that perhaps the pond is "rolling" with temperature, mixing dormant
sulfide from residuals accumulated in circulation "dead spots."
Any history, thoughts, or solutions would be much appreciated?
Thanks.

Joe,
One thought occurs to me. What this aerated lagoon may be experiencing
each Spring is the well-known (to folks operating biological wastewater
treatment plants) seasonal transition from psychrophilic organisms to
mesophilic organisms. Treatment efficiency normally drops off during the
transition period until the different population of organisms becomes
established. Assuming the loading of sulfur -bearing materials coming
into the lagoon stays fairly constant throughout, I would expect that by
early Summer the discharge from the lagoon comes back into compliance
with the sulfide limits.
Hope this helps,
Hugh
