Subject: NPDES Permit Correction
Permit No. NCO026271
Town of Taylorsville WWTP
Alexander County
On May 15, 1995, the Division of Environmental Management issued NPDES Permit No.
NCO026271 to the Town of Taylorsville. Also on May 15, 1995, Mr. John Lesley of the
Division's Mooresville Regional Office and Mr. Joseph Pearce of the Division's Central Office
inspected the Taylorsville Garment Finishers Inc. (TGFI) stonewashing and laundry facility
which discharges to the Town of Taylorsville wastewater treatment plant (WWTP). At the
inspection, TGFI was determined to be a significant industrial user, as defined by
15A NCAC 2H .0903(b)(34), of the Town's WWTP.
Based on a review of the permit file and of the inspection information, it was determined the
permit contained errors related to the pretreatment program conditions. Accordingly, we are
forwarding herewith modifications to the subject permit to correct the errors. These permit
modifications are to the Part III, Special Conditions, and require the development of a Modified
Pretreatment Program.
Please find enclosed amended Part III, Special Conditions which should be inserted into your
permit. The old pages should be discarded. All other terms and conditions contained in the
original permit remain unchanged and in full effect. These permit modifications are issued
pursuant to the requirements of North Carolina General Statutes 143-215.1 and the Memorandum
of Agreement between North Carolina and the U. S. Environmental Protection Agency.
If any parts, measurement frequencies or sampling requirements contained in this permit
modification are unacceptable to you, you have the right to an adjudicatory hearing upon written
request within thirty (30) 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 demand is made, this decision shall be final and binding.

OTHER REQUIREMENTS
A. Requirements for Control of Pollutants Attribute to Industrial Users,
1. Effluent limitations are listed in Part I of this permit. Other pollutants attributable to
inputs from industries using the municipal system may be present in the permittee's
discharge. At such time as sufficient information becomes available to establish
limitations for such pollutants, this permit may be revised to specify effluent limitations
for any or all of such other pollutants in accordance with best practicable technology or
water quality standards.
2. Under no circumstances shall the permittee allow introduction of the following wastes
in the waste treatment system:
a. Pollutants which create a fire or explosion hazard in the POTW, including, but not
limited to, wastestreams with a closed cup flashpoint of less than 140 degrees
Fahrenheit or 60 degrees Centigrade using the test methods specified in
40 CFR 261.21;
b.. Pollutants which will cause corrosive structural damage to the POTW, but in no case
Discharges with pH lower than 5.0, unless the works is specifically designed to
accommodate such Discharges;
C. Solid or viscous pollutants in amounts which will cause obstruction to the flow in the
POTW resulting in Interference;
d. Any pollutant, including oxygen demanding pollutants (BOD, etc.) released in a
Discharge at a flow rate and/or pollutant concentration which will cause Interference
with the POTW;
e. Heat in amounts which will inhibit biological activity in the POTW resulting in
Interference, but in no case heat in such quantities that the temperature at the POTW
Treatment Plant exceeds 40°C (104T) unless the Division, upon request of the
POTW, approves alternate temperature limits;
f. Petroleum oil, nonbiodegradable cutting oil, or products of mineral oil origin in
amounts that will cause interference or pass through;
g. Pollutants which result in the presence of toxic gases, vapors, or fumes within the
POTW in a quantity that may cause acute worker health and safety problems;
h. Any trucked or hauled pollutants, except at discharge points designated by the
POTW.
3. With regard to the effluent requirements listed in Part I of this permit, it may be
necessary for the permittee to supplement the requirements of the Federal Pretreatment

PART III (continued)
F. CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit chronic toxicity 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 at which there may be no observable inhibition of reproduction or
significant mortality is 4.4% (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 the effective date of this permit during the months of January, April, July and October.
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 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 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.
