ACUTE TOXICITY TESTING REQUIREMENT
Daphnid 48 hr - Quarterly Monitoring
The permittee hall conduct acute toxicity tests on a quarterly basis using protocols defined as
definitive in E.I.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. 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 561' Dom- M#4i.
The parameter;i code for this test if using Daphnia pulex, is TAA3D. The parameter code for this test
if using Ceriodaphnia is TAA3B. All toxicity testing results required as part of this permit
condition will Ix entered on the Effluent Discharge Form (MR-1) for the month in which it was
performed, using the appropriate parameter code. Additionally, DEM i Form AT-1 (original) is to
be sent to the following address:
Attention: Technical Services 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 anytest data from either these monitoringrequirements or testsperformed bythe North
o
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.

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 Imortality is 37 % (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 see ,aEc doe wAl 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 oc 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 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.

5/30/89-effective date for pretreatment permit schedule of compliance for Hatch Mills. For inability to
comply with tox limit in their prtrtmnt permit. Notes that compliance will require develpmnt of
alternative solns to alley noncompli at POTW disch point. Activities include the following: moving
portion of dye operation to another plant, eval pilot scale act carbob absorp and powdered act
carbon, eval full scale addition of polymer. These activities, selection of process altern, and tox
reduc plan by 6/15/89. During prtrtmnt SOC, Hatch Mills tox monit req is to conduct chr p/f tests
(monit only) on monthly basis for Columbus WWTP efflu at 37%.
11/16/88-letter to Mouberry from ARO re. compliance schedule for Town. Requests that permit be
modified to include Hatch Mills proposed schedule. ARO suggests interim effluents page to
remove toxicity limitations
10/26/88-letter to Town from ARO stating that proposed schedule by Hatch Mills is adequate and
recommends that Town modify Hatch Mills pretreatment permit to incorp. the schedule. Notes that
NPDES permit will be modified with the proposed schedule and will include interim and final
effluent limitations.
10/19/88-letter from Town to region noting the receipt of Hatch Mills proposed time table for toxicity
reduction project. The two alternative trtmnts previously considered were found ineffective. Hatch
Mills requests more time in completing Process Study phase and submits compliance operation by
11/1/90.
1/15/88-letter from ARO(Mike Parker) to Milliken Hatch plant concerning review of Phase 1 TRE
conducted by BRI for Milliken. Noted progress due to elimination of possible toxicants and
identification of other possible sources but that monthly bioassay results(Nov,Dec) indicate
unidentified probs still exist. ARO requested Milliken Hatch to schedule meeting in early April to
discuss effects of acrylic dyes and its interaction w/ polymer used at T. of Columbus WWTP.
11/25/87-final report of Hatch Mill and T. of Columbus Phase I TRE. Summary of TRE findings:

Hatch plant effluent indicated as primary contributor of toxic wastestream to Columbus WWTP.
Tox characterization bioassays of TOC WWTP efflu identified organic chems as
toxic fraction(alkyl phenol ethoxylates-APEs and quaternary ammonium cmpnd-BTMAC). 2
special studies conducted w/ Columbus WWTP aeration basin mixed liquor supernatant and final
effluent showing decreased tox levels (Prior to period of special studies, Hatch plant had reduced
acrylic fiber dyeing more than 50% resulting in 50% reduction of wastewater flow to Columbus
WWTP.It was also learned that polymer feed rate by POTW operators had been reduced 75%
during this time.) The improved quality of Hatch's effluent(LC50's over typical value <5.0%) was
attributed to reduced Chem usage. Hatch plant's produc of dyed acrylic yarn will not resumm until
3/88 so until then, use of BTMAC is greatly reduced or nonexistent. Recommende that no further
TRE studies be undertaken until Hatch resumes normal produc of acrylic dyeing and until
concurrent Columbus WWTP modifications are complete and operation optimized. Suggested that
estimations of BTMAC pass -through from Hatch plant to the POTW and its biodegration and
toxicity be conducted. In the interim, indicated that acute bioassay data will still be useful to
identify any correlation between efflu tox and BTMAC/polymer.
10/27/87-effluent toxicity test recvd for Hatch Mill -Oct 14 Ac test with P10 at 100% effluent.
6/1/87 - Hatch Mills w/assistance from Burl. Research (Sam Moore) sent Town of Columbus a TRP
(Phase 1) w/time schedule (TRE to be implemented 3rd week of July). Objective of Phase I - biol
& chem charact. of Town's effluent toxicity, biol & chem charact. of indirect and domestic
sources, review chem usage to Hatch Mills, cont. effl. bioassay & chem monit.
Oct 20-25, 86 - flow-thru done @ Columbus plant by DEM aquatic tox, 168 hr C. dubia - LC50 2.4%, 48
hr D. pulex : influent - <5%, effl. - 7.9%, 96 hr fathead - 77%
4/8/87 - memo to Mouberry from ARO pointing out Hatch Mills as main source of town's tox problem -
recommended that town's permit be reopened to incl. tox limits.
3/9/87 - meeting w/ARO, Town, Hatch Mills to discuss tox red efforts by town (w/focus on Hatch).
Town is requiring IU to initiate TRP, submit plan of action to Town by 3/31/87, require
compliance w/tox limits by 9/30/87, submit monthly progress reports (beg. 4/87), & perform BM
tox tests until tox levels are acceptable. ARO expressed concern that IU has not made adequate
progress in toxic reduc. considering when toxicity was detected. Noted that ARO would
recommend that Town's NPDES be reopened to incl. tox limit and emphasized this basis for an
enforcement action against ALL involved parties - Town or Hatch Mills
3/2/87 - letter from Town to Hatch Mills indicating & presenting toxicity data for the TU concluding
Town's source of tox is the IU. Requested the IU to initiate a TRP - submit written plan of action
by 3/31/87, establish completion data of Sept. 30, 1987, monthly progress reports, & must do BM
testing.
CONCORD ROCKY RIVER WWTP(NC0036269) MRO,permit chronic limit:72.6% Q P/F 7/1/87.
11/3/88-Ray Furr of Concord WWTP spoke w/L. Gabele about doing full -range chronic test in place of Q
P/F. Facility is performing surfactant study. Said full range O.K. as long as 73% was used as one
of chronic test dilutions.
9/7/88-Facility's submittal of 7/88 and 8/88 test results (pass and fail). Noted that 8/88 failure may have
been due to their largest industrial contributor's (Fieldcrest Cannon)bypass of prtrtmnt facility
which occurred during that sampling event.
3/15/88-MRO issued follow-up to their 3/9/88 NOV by noting that the facility had brought an error to thr
Region's attention. Error was that Concord had submitted chronic test result with 10/87 DMR and
