STATEMENT REGARDING TWO DOMESTIC WASTE TREATMENT PLANTS
The facility operates two Aerobic Digestion Sewage
treatment plants. One has a capacity of 5,000
gallons/day and the other a capacity of 15,000
gallons/day. Both are now included in the present NPDES
Permit NC0005177. Extended treatment is provided by the
treatment lake and the two waste streams are ultimately
discharged through Outfall 001. Many efforts are being
made to eliminate chlorine in the effluent from outfall
0011. FMC Corporation asks that chlorine disinfection
specified in the existing permit for the 15000 GPD plant,
be dropped. Chlorine disinfection has never been
specified for the 5000 GPD treatment plant.

Dear Ms. Barona:
tLi-k
fMC
Please refer to our application for renewal of our Permit
No. NC0005177. This renewal application was submitted on
March 7, 1991 and is still pending.
In Attachment 001-G to our application we requested that
effluent concentration limits be written for several
discharge volume levels, namely 0.300, 0.400, and 0.500
million gallons/day. We are now asking that you expand
this to include discharge limits if we should elect to
discharge at 0.100 million gallons/day. We will also
want to retain the options requested in our original
application.
Please contact me if you have questions.
Sincerely yours,
Arthur S. Gillespie, r.
Environmental Manager

Facility Name FMC CORP.-LITHIUM DIVISION Permit # NC0005177_ Pipe # 001 _
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 _78 % (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_
JAN APR JUL OCT... 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 (M 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:
Y g
Attention: Environmental Sciences Branch
North Carolina Division of
Environmental Management
4401 Reedy Creek Road
Raleigh, N.C. 27607
Test data shall be comilete 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 tie 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 dalys of initial monitoring event). Failure to submit suitable test results will constitute
noncompliance with rfionitoring requirements.

identify such compounds is made through comparison of the mass spectra of these
unknown compounds in the sample with approximately 50,000 spectra contained in the
computer's mass spectral library. Analytical standards are not utilized in this
procedure and therefore, compounds identified in this manner are referred to as
"Tentative" identifications.
IEA personnel identify and classify, these compounds using identification guidelines
provided by the USEPA under the Contract Laboratory Program (CLP). A gross
estimation of concentration is accomplished by comparing the response of the
unknown compound versus the nearest internal standard in the total ion chromatogram.
As per EPA CLP guidance, TIC's are identified and quantitated only if the response
is equal to or greater than 10% of the nearest internal standard. Compounds
identified as "unknown" are not uncommon utilizing these guidelines since the
requirements fo even a tentative identification are quite stringent.

Biomonitoring of UT Abernathy Creek and A'bemathy Creek below

June 1987 and March 1993, Subbasin 030837, NPDES # NC005177

INTRODUCTION
FMC Corporation (formerly Lithiurin Corporation) discharges to an unnamed tributary
(UT) of Abernathy Creek in Gaston County, comprising about 83% of the flow under
7Q10 conditions. This discharge includes some domestic waste and cooling water, but the
main contribution has been from the processing of lithium ore.
Detailed studies of the Lithium Corporation discharge (toxicology and benthos) were
conducted in June 19874by the Division of Environmental Management. This discharge
was found to be highly toxic, with both chlorides and various lithium compounds
contributing to water quality problems. Since that time, FMC Corporation has installed a
variety of new processes to improve the quality of their discharge, including reverse
osmosis reclamation of lithium, lithium hypochlorite scrubbers, and solids reductions.
Although the company is still failing self -monitoring chronic toxicity tests, they have
documented a reduction in the toxicity of their discharge. Most of these process changes
were completed by the end of 1992, and by now the discharge would be expected to have
less impact on stream fauna. This hypothesis was tested by re -sampling sites from the
1987 macroinvertebrate survey.
METHODS
Benthic macroinvertebrates were sampled at all stations using DEM's standardized
qualitative collection method. This method uses a wide variety of collection techniques (10
samples) to inventory the aquatic fauna and produce an indication of relative abundance
(Rare, Common, Abundant) for each taxon.
Several metrics can be used with these qualitative samples to detect any water quality
problems. EPT taxa richness,(EPT S: taxa richness for the most intolerant groups) can be
used with DEM criteria to assign water quality ratings (bioclassification). EPT abundance
(EPT N) and total taxa richness calculations also are used to examine between -site
differences in water quality. Unstressed streams and rivers have many species, while
polluted areas have fewer species.
Water quality assessments also may evaluate the relative tolerance of macroinvertebrate
species, especially the abundance of "pollution indicator" groups. This type of information
is summarized with a Hilsenhoff-type biotic index. Both tolerance values for individual
species and the biotic index vary from 0 to 10, with higher numbers indicating more
tolerant species or more polluted conditions. Water quality ratings assigned with the biotic
index numbers are combined with EPT taxa richness ratings to produce a final
bioclassification.

Two other indices also can be used with this data set to compare sites: a Common Taxa
Index (CTI and a Common Dominants Index (CDI). These two indices are based on
Arkansas criteria and always compare paired sites (usually a downstream site and an
upstream control). Both the CDI index and the CTI look at the species which are found at
both sites (1 common taxa) and vary from 0 to 100%. Sites may be compared statistically
using a Wilcoxon Signed Rank test, with taxa richness (by group) as input data.
SITE DESCRIPTIONS (Figure 1, Table 1)
Abernathy Creek. Two stations were located on Abernathy Creek near SR 1302,
Gaston 'County. Station 1 was located just above the UT, while Station 3 was located
about 100 meters downstream of the UT. Station 1 was slightly narrower than Station
3 and had a higher proportion of boulder/bedrock substrate. Both sites, however, had
good boulder/rubble riffles and would be expected to have very similar invertebrate
communities. Abernathy Creek receives nonpoint source runoff from the Kings
Mountain area.
UT Abernathy Creek. Station 2 was located just above the confluence of UT
Abernathy Creek and Abernathy Creek (near SR 1302, Gaston County). This portion
of the stream is large enough to have year-round flow, and is similar in size to
Abernathy Creek Station 1. The FMC Corporation discharge is located about 0.5 miles
upstream.
RESULTS AND DISCUSSION (Table 2, Appendix 1)
Comparisons between the 1987 and the 1993 collections must be made cautiously, due
to the large between -year changes at the control site (Station 1). There were seasonal
changes in the taxa present at this site, with more spring/summer species collected in 1987,
and more winter species collected in 1993. Between -year differences in flow may have
affected results in two ways: through differences in scour and through changes in the
dilution of FMC's effluent. The lower flows in 1987 would be expected to have caused
less scour than in 1987, producing a more diverse and abundant chironomid assemblage.
The higher 1.993 flows would have resulted in greater dilution of the FMC discharge, with
less impact io stream fauna. For these reasons, the following analyses focus on between -
site differences in each year of collection, and do not examine between -year changes for
specific taxa.
1987 Survey. There was a large difference between the Abernathy Creek sites in
1987 despite the short distance (100 meters) between Stations 1 and 3. Intolerant EPT
groups wereh absent at UT Abernathy Creek and rare at station 3. Several of the EPT
species at Station 1 would be prone to daily downstream "drift", particularly Baetis
flavistriga ar?d Baetis pluto. The absence of these potential colonizers at Station 3 clearly
indicated that the discharge was acutely toxic to many stream invertebrates, even after
dilution by .-bernathy Creek waters. Both the UT Abernathy Creek and Abernathy Creek
station 3 received a Poor bioclassification in 1987, while the upstream site on Abernathy
Creek was rued as Fair.
1993 Survey. Some EPT taxa were found at UT Abernathy Creek in March 1993,
although on1S, Caenis (a fairly tolerant genus) was abundant. The dominant taxa at this site
were Chironmidae (Diamesa, Cricotopus/Orthocladius) and Simuliidae (Simulium
A1 vittatum). though some between -year improvement was observed at this site, it still
received a Poor rating in 1993.
Although there were very large differences between station 1 and 3 in 1987, only minor
changes wer6 seen in 1993. Both sites received a bioclassification of Good -Fair in 1993.
EPT taxa ric ness was almost identical at both sites, although many of the more intolerant
species were lower in abundance at the downstream site. The chironomid community

shop-. _d large between -site changes. Chironomidae were fairly sparse at Station 1 with a
facu:�tive species (CIO sp20) being most abundant. Chironomidae, however, were
abundant at tation 3, with a toxic -tolerant species (CIO sp5) being most abundant. This
shift species resulted in a higher biotic index at Station 3 (6.93) than at Station 1 (6.18).
The Common Dominants and Common Taxa Indices still indicated large between -site
differences for individual taxa, but the Wilcoxon signed -rank test indicated no significant
differences in community structure.
CONCLUSIONS
Lithium Corporation's discharge was found to have a very severe toxic effect on the
aquac faun of UT Abernathy Creek and Abernathy Creek in 1987. Since that time, this
com:any (n w called FMC Corporation) has upgraded their waste treatment, leading to a
reduction in the toxicity of the effluent. A resurvey of the stream fauna in 1993 indicated
that CT Abernathy Creek was still rated as Poor, but both stations on Abernathy Creek
(abo•: e and below the UT) were rated as Good -Fair in 1993. Some impact is still evident at
this s te, indicated by a reduction in the abundance of intolerant taxa, changes in the
Cor non Taxa and Common Dominants indices, and an increase in certain toxic -tolerant
spec:es. However, there is evidence of,a substantial improvement in the water quality of
Abe-►athy Creek between 1987 and 1993, especially the lack of significant between -site
differences in taxa richness. Both the reduced toxicity of the effluent in 1993 and the
grea:er dilution of the effluents by high 1993 flows could have contributed to these
char.zes.
