MEMORANDUM
TO:
December 29,1993
Coleen Sullins
Permits and Engineering
FROM: Betsy Johnson
Instream Assent
SUBJECT: City of Lexington WLA
NPDES No. NC0055786
Davidson County
The metals and toxicity test were changed based on a revised 7Q10. There is a gage in
close proximity to the discharge location. The flows for the Abbotts Creek watershed
were updated for the QUAL2E model which was calibrated. The new flows will be used
for all discharges in this watershed. I have revised the metals limits (see attachment)
after looking at the communication file, information from adjudication, Susan Wilson's
review of silver and cyanide in 1992, and monitoring data. As before, limits will apply
for mercury and lead only. However, in addition to the flow change, the mercury
standard has changed from 0.2 ug/1 to 0.12 ug/1 since the previous WLA. Note: there is
no benefit to having both a daily max and weekly average for lead.
A compliance schedule should be developed if needed for metals and toxicity. Again the
TP and TN limits should be met by 1998. However, immediate efforts should be made
to reduce effluent nutrient levels.
Both instream monitoring sites are existing sites. This is a reduction in monitoring from
the previous permit. While vertical samples are required at the lower site (it is a lake
station and stratifies in summer), only two sites are required of Lexington; Thomasville
and High Point will each receive three instream montioring locations.

Wasteload Allocation Summary
(approach taken. correspondence with region. EPA. etc.)
Discharge is to the transition area between stream and lake of the Abbotts Creek arm of High Rock Lake.
Extreme water quality impacts - DO, eutrophication, toxics....The existing limits for Thomasville, High Point, and
Lexington represent advanced tertiary treatment but do not protect water quality. Since this will be a five year
permit, nutrient limits should be included at this time. Localized nutrient impairment in Abbotts Creek is well
documented. Algal blooms and chlorophyll -a violations regularly occur. Insraeam levels of nutrients exceed
DEM's targets for prevention of algal blooms. Per our SOP, limits of TP = 0.3 mg/1 and TN = 3.0 mg/I are
recommended due to the instream waste concentration. However, technology limits of TP (mg/1) = 0.5 and
TN (mg/1) = 4.0 (8.0) for summer (winter) will be required. Immediate efforts should be made to reduce effluent
nutrient levels. An implementation schedule should be developed for compliance with these limits by 1998.

Permit # NcLD SS788 Pipe # dD l
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 Ccrioda_phnia 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 .% (defined as treatment two in the North Carolina procedure document). The permit holder shall perform
quarter& 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
permitted final efiluent'°dischar a below all�treatment
sampling for this testing shall be performed at the NPDES
g 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 wens 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.
