Wasteload Allocation Summary
(approach taken, correspondence with region, EPA, etc.)
Facility requesting renewal of existing NPDES permit. Updated pretreatment information adds
mmonitoring_to.the wasteload allocation. Previously recommended metals monitoring in the
1987 WLA was not included in the last permit. Review of PPA data collectedin December 1991
indicates that limits for mercury, selenium, and arsenic are needed. Color monitoring is
recommended because Tryon's effluent adds color to Vaughn Creek.

CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QRTRLY)
(**Chronic Toxicity (Ceriodaphnia) P/F at IL%, 4fAR i2'✓ fe P(C, $ee Part , Condition .)
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 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 the effective date of this permit during the months of
SEP pc c MAk. . 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. 27607-6445
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 immediatelyuntil 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.

DIVISION OF ENVIRONMENTAL MANAGEMENT
Recommendations for Color Monitoring
1
Per 15 A NCAC 2B.0211(b)3(F) for colored wastes, the permittee shall discharge
only such amounts as will not render the waters injurious to public health,
secondary recreation, or aquatic life and wildlife or adversely affect the
palatability of fish, aesthetic quality or impair the waters for any designated
uses.
For the purpose of measuring compliance with this requirement, the permittee
shall perform the following:
Within 120 days of the effective date of this permit, the permittee shall begin
monitoring for color at the Effluent, Upstream, and Downstream at
designated sites (see part I.A.).
The samples shall be analyzed using the Spectrophotometric Method (2120 C.)
in the 17th edition of Standard Methods. The calculations must be done using
the weighted ordinance method. The test should be performed using a spectropho-
tometer with a 2.0 nanometer (nm) band pass and 50 millimeter cell path. The
operating range should begin at 400 nm and end at 700 nm (using 10 nm intervals)
and measure transmittance values at 31 wavelengths. The results shall be
calculated and reported in ADMI color units from the information indicated (see
reference below for worksheets and examples for calculation of ADMI values).
Analyze samples free from turbidity or at "true color" through the filtration
method using a .45 micron filter (centrifugation is not necessary).
Samples shall be collected on 3 consecutive days (between Tuesday and Friday)
during each month for twelve months following permit issuance, and on 3
consecutive days per quarter thereafter. Effluent samples shall be composited
over 24 hours, while instream samples shall be grab samples. For Publicly -Owned
Treatment Works (POTWs) with an approved pretreatment program, this sampling
regime (or alternative monitoring program approved by the Division's Pretreat-
ment Program) should be incorporated within the POTW's approved headworks
long-term monitoring program which should also include monitoring to assess
industrial sources of color and POTW color removal efficiency.
For the purpose of reporting: The ADMI values shall be reported at natural and
standard pH (7.6 SU) for all three sites. In addition to the ADMI measurements
reported on the permittee's DMR, the permittee shall attach a narrative
description of visual observations made during each sampling event using a form
provided by the Division. Such a description shall include perceived color in
the effluent and receiving stream (i.e. whether effluent plume is noticeable
and, if so, the approximate width and length of the plume), rainfall, and
streamflow.. Also, the permittee shall verify on this form that the type of
spectrophotometer (indicating band pass (nm) and cell path (mm)) employed, and
method used for filtration are in accordance with the requirements of this
permit condition.
