Subject: NPDES Permit Issuance
NPDES No. NC0005177
FMC Corp., Lithium Division
Gaston County
Dear Ms. Ritc 'e:
In accordance with the application for a discharge permit received on April 4, 1996,-the
Division is fo arding herewith the subject NPDES permit. This permit is issued pursuant to the
requirements lof North Carolina General Statute 143-215.1 and the Memorandum of Agreement
between North Carolina and the U.S. Environmental Protection Agency dated December 6,1983.
In response onse to your comment letter of December 13,1996, several changes have been made
to this final permit. Please refer to the appropriately numbered comment in your response letter.
1 & 2) Since the permit has already been through the public notice process.the Division does not
deem it necessary, nor does it intend to renotice the permit. For your information BOD5 is the
parameter that is water quality limited.
3) On the Supplement Page, the flow has been changed from 0.015 MGD to 0.010 MGD.
4) Effluent from the R & D pond will also be permitted to discharge via Outfall 004. It is the
Divisions un4erstanding that flow from the R & D pond will only be directed to outfall 004 when
necessary to 7vert overflowing the pond.
5) With the elimination of monitoring and limits for bromodichloromethane and
dibromochloromethane all of the limits for flows below 0.615 MGD are the same, therefore there
is no need Mir individual effluent pages for the lower flows. In addition, past data show that
discharges are typically in the range of 0.4 to 0.6 MGD. Separate limits pages have been included
for the following flows: 0.615 MGD, 0.70 MGD, 0.80 MGD and 0.90 MGD.
6) A review of the self monitoring data submitted from 1994 to 1996 indicates that most of the
reported val des for these parameters are below detection. However, these constituents remain
parameters o concern. Based on the reported values, monitoring for copper and zinc will be
reduced to qu erly and monitoring for chromium will be reduced to annually. Detection levels for
copper and zl nc should not vary from month to month. Please inform the laboratory to use a
consistent det ction level.
7) The 1'mit for TSR applies only to the effluent and not upstream nor downstream. The
addition of upstream and downstream monitoring is warranted based on the potential for the
discharge to contain high TSR and degrade water quality in the receiving stream. Since the 004

outfall is the upstream sample location for outfall 001 all upstream monitoring for 001 has been
incorporated into the 004 monitoring requirements.
8 Effluent monitoring for chlorides was added to the permit to determine the level of
chlorides being discharged. This facility has consistently failed itss toxicity
test
and Effluent
st
documentation indicates that chlorides may be a contributor to thetoxicity problem.
monitoring
for chlorides will help to determine whether high concentrations
of chlorides ne
are
causing toxicity. If effluent monitoring indicates that no significant amount of g
discharged, FMC can request to have this requirement removed or monitoring frequency reduced
after twelve months of monitoring.
9 It is the Division's understanding that the instream monitoring sites described in yur letter the
are the same monitoring locations specified in the last permit. Therefore, the description
downstream location has been modified as you requested. The description of the upstream
monitoring site is no longer required and has been removed (see note 7).
10) Language for flow monitoring has been added that will allow for flow to be calculated
based on the amount of rainfall, impervious area, and total drainage area draining to outfall
11) See note 7.
12) Since FMC does not add chlorine nor does FMC intend to use chlorine in the treatment
system the footnote number 4 has been removed.
13) The Biocide Worksheet Form 101 must be completed or all water treatment chemicals
which may be discharged via an outfall if a whole effluent toxicity test is not performed on the
discharge.
14) Part I, Section C, has been modified to pertain to areas draining to outfall 004. In addition,
the intent of the certification in Part I, Section C (a.) 5 is to have FMC remove non-stormwater
discharges that are not covered elsewhere within the permit.
• 15) Monitoring reports are required to be submitted monthly. Part I. D., items c and d have
been eliminated to clarify reporting requirements. Item b has been modified and moved to footnote
2 under outfall 004. As noted in the footnote, at least one sampling event per year shall be a
stormwater sample taken during a representative storm event. Item e has been modified for
clarification. Since outfall 004 is considered primarily a stormwater outfall, semi-annual visual
monitoring has been added under Part I. B. (2).
16) As you are aware, all secondary containment of bulk liquid storage was to be completed by
February 1, 1997. The Division has noted that in Mr. Hopkins letter dated January 29, 1 �d
FMC has implemented secondary containment of all bulk liquid storage tanks which
are in use anticipated to be in use in 1999. The Division also noted that FMC has committed to the
installation of secondary containment systems prior to the re -activation of any in -active storage
tank. Therefore, the Division grants a waiver from the secondary containment requirement for
those bulk liquid storage tanks that will be removed from service by December 31, 1998, as
mentioned in the January 29, 1997 letter. However, FMC shall install secondary containment
prior to re -activation of any inactive storage tank covered by this condition.
Lastly, FMC requested clarification of the status of the toe drain. This type of discharge is
covered under the "Deemed Permitted" section of the 2H .0106 rules, and does not require a
permit to discharge

Raleigh, North Carolina 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 stre .
Should there be no discharge of flow from the facility during a month in which toxicity monitoring is
required, the permittee will complete the information located at the top of the aquatic toxicity (AT) test
form indicating the facility name, permit number, pipe number, county, and the month/year of the report
with the notation of "No Flow" in the comment area of the form. The report shall be submitted to the
Environmental Sciences Branch at the address cited above.
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 the pen` 'ttee fail to monitor during a month in which toxicity monitoring is required, 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 Water Quality 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, minimum control organism reproduction, and appropriate environmental controls,
shall constitute 4n invalid test and will require immediate follow-up testing to be completed no later than
the last dayof the month following the month of the initial monitoring.

sampled and measured, divided by the numbcr of daily discharges sampled and/or measured
during such week. It is, therefore, an arithmetic mean found by adding the weights of
pe:::::ants found each day of the weex and men dividing this sum by the number o: days the
tests were reported. This limitation is identified as "Weekly Average" in Part I of the permit.
c. The "maximum daily discharge" is the total mass (weight) of a pollutant discharged during a
calendar day. If only one sample is taken during any calendar day the weight of pollutant

SUBJECT: Comments on Draft NPDES permit for FMC Corporation
NPDES Permit No. NC0005177
Gaston County
Z kr ow that you are On a fast track for reviewing and getting a response out.
However, he Ir)stream Assessment Unit did want to submit a written response to FMC's
draft coin' entsi..,To the following designated items.
#6. Monthly monitoring for chromium, copper and zinc. A review of
the self monitoring data submitted from 1994 through 1996 does indicate that most of the
reported values for these parameters are below detection. However, the reasonable
potential aralysis indicated that some type of monitoring is still recommended for ail the
parameters Regarding chromium with 27 of 29 reported values below defection, we will
recommenC annual monitoring. For copper and zinc, we will recommend that the facility
request that the laboratory use the same detection level rather than varying, from month to
month. Th_s affects the analysis when a value that would be undetected with a level of <10
µ.g/1 in May, becomes a detectable value when a level of <2 mil is used in June. We will
recommenc a reduced frequency of quarterlmonitoring for copper and zinc because they
are action l �vels, but in both cases, the analysis predicted values greater than the allowable
concentration.
#7. Limit and instream monitoring for TSR - The. effluent limit for TSR
was modified based on updated information submitted by P&E. TAU applied this limit to
outfall 001. The instream monitoring was added because of the large increase in the
concentrati n to be discharged. Since the UT Abernethy Creek has a Poor biological rating,
instream m nitoring was included to see the impact that TSS would have. Historical
instream da a also shows that levels for total dissolved solids increase from the upstream
site for 001 designated in FMC's self monitoring data as "West Canal" to the: downstream
site of UT he.rnethy Creek. If this parameter is being measured for outfall (.)04 at the same
downstrean location , then it can be deleted from outfall 001's requirement.

sometimes increases as much as 7 times higher than the tiptiiream value and

chlorides at 0.615 MGD is 295 mg/I, however the actual concentration is unknown because
no efiluen4 monitoring is required. If effluent monitoring indicates that this amount is not
discharged, FMC can request that the requirement can be deleted after twelve months of
monitoring.
#9r lnstream Monitoring Sites for Outfall 001 - IAU has not

West Can 1 and the downstream site, immediately downstream of outran in UT Abernethy

Comme its on Draft NPDES Permit
Dear Mr. Goodrich:
FMC Corporation's Lithium Division facility in Bessemer City
("FMC") received a copy of the draft NPDES permit, No. NC0005177,
on November 14, 1996. This draft permit was transmitted with the
Division of Water Quality ("DWQ") letter of November 12, 1996,
over your signature which states that all questions or comments
on the draft permit should be directed to you within 30 days of
receipt. FMC is herewith providing DWQ with questions and
comments which FMC requests DWQ address prior to issuing a final
version of NPDES permit No. NC0005177. FMC has organized these
questions and comments to coincide with the sequence in which
they appea in the permit.
(i. Public Notice of intent to issue a State NPDES permit to the
following - This narrative states that one parameter is ater
quality limited. FMC requests that DWQ identify the
parameter which is water quality limited.

2. Public Notice of intent to issue a State NPDES permit to the
following - FMC requests that this section state that the
renewal of NPDES Permit No. NC0005177 includes provisions for
the discharge flows currently permitted under NCS000002 and
that upon issuance of N00005177, permit No. NCS000002 will be
canceled.

3. Supplement to Permit Cover Sheet - Item 1 describes the flows
associated with Outfall 001 and contains a typographical
error. FMC operates one 0.005 MGD domestic treatment
facil}ty and one 0.010 MGD treatment facility; the 0.015 MGD
flow hown in the description should be changed to 0.010 MGD.
4. Suppl ment to Permit Cover Sheet - Item 2 describes the flows
associated with Outfall 004. FMC requests that effluent from
the R•CD Pond, which may be discharged via Outfall 001, also
be permitted to be discharged via Outfall 004. The R&D Pond
is used to collect waters which are recycled as recirculating
cooling water. Stormwater is collected in the pond and in
perio s of prolonged and extreme wet weather, rainfall can
overt kes FMC's evaporation of cooling water, which may occur
annually or less frequently, the pond will require discharge.
FMC requests the flexibility to discharge this pond to either
permitted outfall as needed to control pond level.

,Outfall 001. FMC also requests that the lower flow rates
c6YAFi;'4' [` IN`'F'L''� remain in the permit to provide for greater flexibility in
chronic bioassay compliance during low flow periods.
6. Permit Part I.A. - This part includes effluent limitations
and monitoring requirements for Outfall 001. Monitoring for
chromium, copper and zinc has been required monthly in the
previous NPDES permit and FMC believes that the effluent

Mr. David Goodrich
NPDES Permit NC0005177
December 13, 1996 - Page 3
characteristics for these metals has been sufficiently
monitored to either drop the metals from the permit as
historical results do not indicate a water quality issue, or,
as a minimum, reduce the monitoring --frequency to annually.
. Permit Part I.A. - This part includes effluent limitations
and monitoring requirements for Outfall 001. Newly added
monitoring requirements include monitoring "upstream" and
"downstream" for total suspended residue ("TSR") in addition
to monitoring the effluent for TSR. FMC's first concern is
that the permit, as written, is ambiguous as TSR is limited
to specific monthly average and daily maximum and it is
unclear to which sample location these limitations apply.
Second, FMC has monitored TSR at Outfall 001 for years,
consistent with the applicable categorical discharge
limitation for manufacturers of lithium carbonate and shown
compliance with these standards. The addition of monitoring
"upstream" and "downstream" is not warranted, nor consistent
with the categorical limitations. Lastly, this monitoring
requirement is redundant with those specified for Outfall
004, as discussed later in these comments.
-4-8. Permit Part I.A. - This part includes effluent limitations
and monitoring requirements for Outfall 001. Newly added
monitoring requirements include monitoring the effluent for
chlorides, in addition to monitoring "upstream" and
"downstream" for chlorides. FMC has historically monitored
upstream and downstream for chlorides and based on those
results, does not believe that the additional requirement to
monitor chlorides as Outfall 001 is justified.
9. Permit Part I.A. - This part includes effluent limitations
and monitoring requirements for Outfall 001. The
descriptions of the sample locations for "upstream" and
"downstream" have been modified to specify the upstream
sample location as "upstream at the west canal" and the
downstream location as "immediately downstream of outfall in
unnamed tributary to Abernethy Creek." FMC suggests that the
following language as more accurate and consistent with the
August 1995 report on regulated discharges submitted to and
approved by DWQ pursuant to Stormwater NPDES Permit No.
NCS000002.
"U - Upstream in the West Canal at Outfall 004"
"D - Immediately downstream of the convergence of Outfalls
001 and 004"

Mr. David Goodrich
NPDES Permit NC0005177
December 13, 1996 - Page 4
The remainder of FMC's comments concern the provisions in the
permit WO relate to Outfall 004 and, as FMC requested, DWQ's
incorporation of the provisions of stormwater permit No.
NCS000002 into a traditional wastewater NPDES permit. FMC has
generally grouped these remaining comments into two sections:
First, those specific to the provisions relating to Outfall 004
and, second those which appear to stem from the logistic
challenges of modifying the permit language related to
incorpora ing stormwater provisions.
Issues specifically related to Outfall 004 -
10. Permit Part I.B. - This part includes effluent limitations
and monitoring requirements for Outfall 004. The permit
states monthly monitoring is required for instantaneous flow
at Outfall 004. FMC has installed a rectangular weir at
outfall 004 which, pending recalibrations, is estimated to be
accurate in the flow range of 0 to approximately 2,359 gpm.
Nonetheless, due to the large area which drains to outfall
004, Turing extreme periods of high rainfall, the flow rate
at Outfall 004 may exceed this upper rate at the time of
monthly monitoring. FMC requests that Footnote 2, relating
to flow monitoring, be modified to include the following
langu ge:
'Where no measurable discharge occurs at the time of
sampling, "no discharge" should be clearly noted on the
submitted monthly discharge monitoring report. When flow
rae at the time of sampling exceeds the maximum
measurable flow rate, "greater than 2,300 gpm" should be
reported on the submitted monthly monitoring report.'
11. Permit Part I.B. - This part includes effluent limitations
and monitoring requirements for outfall 004. Monthly
monitoring of TSR at Outfall 004 is required. This provision
is redundant with DWQ's proposed requirement in Permit Part
I.A. to monitor TSR 2/month "upstream of outfall 001 in the
west ;anal" as this sampling location is Outfall 004. As
state above, in comments relating to Permit Part I.A., FMC
does not believe this requirement is justified, and in no
case should TSR be required for Outfall 004 as well. as
upstream of Outfall 001.
12. Permit Part I.B. - This part includes effluent limitations
and monitoring requirements for Outfall 004. Footnote No. 4
speci ies that Total Residual Chlorine must be monitored only
"if c lorine is added to the treatment system." FMC does not

Mr. David Goodrich
NPDES Permit NC0005177
December 13, 1996 - Page 5
add chorine to the treatment system nor does it intend to add
chlorine to the treatment system. As the stipulation that
the "Permittee shall notify theDirector in writing not later
instituting pinety (90) days prior to use of any
additional biocide used the the treatment system," also
appears in the permit, FMC believes that the references to
Total Residual Chlorine should be dropped and addressed in
the general provisions for changes to FMC's use of biocides.
13. Permit Part I.B. - This part includes effluent limitations
and monitoring requirements for Outfall 004. Provisions at
the bottom of the section address the use of biocides in the
treatment system and the requirement to notify DWQ of the use
of any biocides not previously reported to DWQ. FMC
understands that this inherently grants authorization for the
use of water treatment chemicals that were listed in FMC's
NPDES permit application. FMC also requests a copy of
Bioci a Worksheet Form 101.
Issues relating to difficulties in incorporating stormwater
permit provisions into a process/cooling water NPDES permit -
14. Permi Part I, Section C, Stormwater Pollution Prevention
Plan This section lists the required elements of Stormwater
Pollution Prevention Plan ("SWP3"). One of those elements is
a certification that the stormwater outfall has been
evaluated for the presence of non-stormwater discharges. FMC
notes that Outfall 004 is known to continuously discharge
cooling water, condensate, and boiler blowdown, rendering the
certification of limited value. Further, the permit should
be clarified to limit the applicability of this section to
areas draining to Outfall 004. FMC suggests the addition of
a footnote is Permit Part I, Section B which stipulates that
a SWP3 be developed for outfall 004.
15. Monitoring and Reporting Provisions as included in Permit
Part I.B. and Part I, Section D. In several instances these
sections appear to be contradictory and clarification is
required.
A. Permit Part I.B. appears to require monthly submittal of a
disOarge monitoring report. Permit Part I.D., item c and
d appear to require annual reporting of monitoring
results.

Mr. David Goodrich
NPDES Permit NC0005177
December 13, 1996 - Page 6
B. Permit Part I.D., Item b. states that all samples
collected shall be from a discharge resulting from a
representative storm event. This language is consistent
with that found in stormwater permits requiring annual or
semi-annual sampling, not on a monthly basis, and
represents an extreme undue burden for monthly sampling.
Further, it is unknown whether a representative storm
event occurs every month, or during regular business hours
during that month. Further, Permit Part I.B. states that
total precipitation, storm duration and total flow must be
monitored for each representative storm event andtotal
flow shall either be measured continuously or estimated by
the measurement of flows at 20 minute intervals. Again,
this represents an extreme burden if monthly samples are
to be conducted for representative storm events. Outfall
004 is easily a twenty minute drive from FMC's offices
and, given to large area which drains to Outfall 004, in a
significant rain event, an individual could be required to
be located at outfall 004 continuously for greater than 24
ho rs to measure total flow. Further, given that outfall
00fl continuously discharges in all but extreme drought,
the cessation of flow from a storm event is
indeterminable. Finally, the last paragraph in item e in
Permit Part I.D. would appear to duplicate all sampling
an reporting required under this permit as non-stormwater
discharges occur continuously.
C. Permit Part I, Section D, item a stipulates visual
monitoring for color, odor, solids, etc. and that the
first visual monitoring be conducted with the first
analytical monitoring. Again, FMC believes that this is
language typical of stormwater permits where annual or
seti-annual sampling is required. Requiring visual
monitoring in addition to monthly sampling is unduly
burdensome and not justified.
To ad
follo
ress all of these items, FMC suggests that the
ing changes be made:
Footnote 2 in Permit Part I, Section B be modified to state
that once per year one of the monthly sampling events must
coincde with a representative storm event and for that
storm event, total precipitation be measured and total flow
due to the stormwater portion of the discharge be estimated
based on the total precipitation and drainage area.

Mr. David Goodrich
NPDES Permit NC0005177
December 13, 1996 - Page 7
Item in Permit Part I, Section D be modified to state that
visua monitoring at Outfall 004 is required once per year,
during the monitoring of a representative storm event.
Items
c and d in Permit Part I, Section D should be deleted.
The last paragraph in Item e in Permit Part I, Section D
should be deleted.
16. Part II - Schedule of Compliance. Item 1.b. stipulates that
secondary containment as specified in Part I, Section A of
this permit shall be accomplished by February 1, 1997. This
language is drawn from the compliance schedule included in
Stormwater Permit No. NCS000002 but is not complete. It
should read:
"S condary containment, as specified in Part I, Section A,
1. .2. of this permit shall be accomplished by February 1,
199�7 (unless otherwise approved by DWQ)."
This final parenthetical is critical as FMC finalizes its
review of secondary containment systems. FMC is in the
proce s of relocating its source of lithium from a locally
mined spodumene ore resource to a South American brine
resou ce. This brine resource will be processed to a refined
lithi m product in South America and brought to Bessemer City
for final and further processing. In 1997/1998, FMC will be
closing a significant portion of its manufacturing facility
in response to discontinuation of the extraction of lithium
from ore in Bessemer City. Installation of secondary
containment for uncontained tanks located in processing units
to be shutdown is not warranted. FMC will request exemption
from he requirement for secondary containment for tanks and
units to be shut down. Thus, the parenthetical must be
reinstated in the permit language.
If you have any questions, or require additional information,
please contact me at 704/868-0806 or 704/599-1990.

Wasteload Allocation Summary
(approach taken, correspondence with region, EPA, etc.)
Facility requesting renewal with modification of wasteflow to 0.7, 0.8, and 0.9 MGD. Facility
requesting the existing stormwater outfalls be incorporated into NPDES process water discharge.
Expansion flows were run in QUAL2e model of Crowders Creek basin dischargers. Results
indicate that if existing permitted loading for BOD5 held the same, expansion flows can be
allowed. Updated raw material information from facility results in higher effluent guidelines (see
attached) for TSS. Chronic toxicity tests recommended for each wasteflow. Reasonable potential
toxicity analysis recommends deletion of limits and monitoring requirements for
dibromochloromethane, bromodichloromethane, bromoform, and chloroform.

Crowders Creek QUAL2E Model Notes
QUAL2E model for Crowders Creek Basin was updated to remove dischargers that had
ceased discharge, connected to the Gastonia- Crowders Creek WWTP or had no oxygen
consuming waste being discharged. Following dischargers had wasteflow and loading
zeroed out of point loading in model.
1) AB Carter discharges no BOD.
2) MTE Hydraulics - NPDES permit no longer needed
3) Howell Manufacturing connected to Gastonia
4) Dixie Yarns - ceased discharge.
Another revision was the lowering of the SOD rate in the reach of UT Crowders Creek
where Homelite Textron discharges. SOD rate lowered from 0.08 to 0.05 because of the
removal of wasteflow for dischargers listed above on the tributary. Revision made per S.
Bevington. Model results of revisions with dischargers at existing Qws and loadings
predict DO minimums of :
5.63 just below discharge of FMC-Lithium in Abernethy Creek
5.09 in Crowders Creek just below Blackwood Creek
5.24 in UT Crowders Creek below the Homelite discharge
5.47 in Crowders Creek at the end of the model
Model scenarios were run that included the following variations:
1) FMC -Lithium w/ expansion flows to 0.7, 0.8, and 0.9 MGD. Expansion BOD5 limits
were held to the existing loading of 30 mg/1 based on water quality, since there are no
effluent guidelines for BOD5 for this type of facility.
@ 0.7 MGD, BOD = 26.4 mg/1,
@ 0.8 MGD, BOD = 23 mg/1
@ 0.9 MGD, BOD = 20.5 mg/1.
2) Homelite w/ flow reductions of 0.1 and 0.2 MGD. Tried increasing BOD5 and NH3
limits above 16 and 4, respectively, so that DO min. in tributary would not go below 5
mg/1. Could allocate 25 mg/l BODS and 6 mg/1 NH3 (oxygen consuming) @ 0.1 MGD,
and 20 mg/1 BOD5 and 5 mg/1 NH3 (oxygen consuming) @ 0.2 MGD. Should be noted
that NH3 toxicity limits for Homelite are more stringent that the oxygen consuming limits.
At previous WLA 1994, IAU allowed the continuation of the oxygen consuming NH3 limit
since Homelite was consistently passing their toxicity test. If Homelite started to fail test
would look at NH3 as a cause and if necessary, would then apply NH3 toxicity limit.
3) CBP w/ flow expansion to 0.350 MGD. Converted revised effluent guideline BOD5
limit of 306 lbs/day to concentration limit of 104.8 mg/1, ran model with limit of 314 mg/1
(104.8 *3). Predicted DO levels higher because of reduction of BOD concentration even
though wasteflow nearly 0.100 MGD higher.

Note: previous permit omitted effluent monitoring for chlorides and only
included upstream and downstream monitoring. Past documentation from ESB in
1988 indicated that toxicity problems could be attributed to lithium and
chlorids, therefore chlorides monitoring is still needed. Will recommend at this
renewal since instream monitoring is stll required. 1987 ESB report also noted that "lagoon
effluent 1}ad high residual chlorine and also high conductivity indicated that large amounts
of dissolved solids. Effluent was predicted to cause acute toxicity instream during average
stream flows to organisms with w/ similar sensitivity as C. dubia." ESB report also
recommended that lithium monitoring be placed in the permit at the next
permit renewal but it was omitted from the recommended limits. There is no
State standard or federal criteria for lithium, however this substance is being monitored in
the other !'MC (NC0005169) permit because had been detected in the GW. Monitoring for
Lithium may provide some good historical information, if water quality or health concerns
should arse in the future. From Hawley's Chemical Dictionary: Lithium -a metallic
element, a very soft silvery metal. the lightest and least reactive of the alkali metals and the
lightest slid element. Soluable in liquid ammonia. Lithium is derived by electrolysis of a
mixture of lithium chloride and potassium chloride, high temperature extraction from
spodume a by sodium carbonate, solar evaporation of lake brines.Ignites in air near its
meltingpint (179C), dangerous fire and explosive risk when exposed to water, acids, or
oxidizing agents. Extinguish lithium fires only with chemicals designed for this purpose.
Lithium in solution is toxic to the central nervous system.
Toxicity test limits: went into effect, on January 1996. DEM and Lithium had worked
out a schedule where toxicity monitoring would be in effect while Lithium did some
toxicity evaluation and then limit would be added to the permit

FMC has three discharges, 001- siphoned discharge from the lower pond
004 -cooling water, boiler blowdown, condensate, and stormwater discharged through
stormwater conveyances. Drainage from the Toe Drain of the Lower Pond dam. (Seepage
through the earthen dam is directed through the toe drain and discharged via the toe drain
discharge, same constituents that could be discharged through 001 could be discharged
through the toe drain.)
Type of p!ocess: manufacturing and processing of inorganic chemicals, primarily lithium
and compounds (lithium carbonate) and organic chemicals primarily organolithiums and
derivatives.
Also disci arge some domestic sewage treatment. Steam, electric cogeneration, utility
boilers, stbrmwater runoff, Research and Dev. activities.
See atta ed Crowders QUAL2E notes for revised BODS limits at the

Also a shed new effluent guidelines for TSS. Raw materials info gotten from
FMC has n categorized as confidential by the facility. New guidelines for TSS :

333.9 lbs/day /8.34/0.9 MGD = 44 mg/1 Mo. Avg.
Some concern about giving these new guidelines because they are nearly four times greater
than the existing limits of 86.94 lbs/day. Abernethy Creek below the Lithium Corp. has a
biological ling of Poor, and the creek has an overall rating of not -supporting its use
because o a point source.

10/17/88-letter from City re. Sept. chronic bioassay results(fail). Actions taken: reviewed plant operation -
were using extra Cl to meet coliform limits. Reviewed lab data -concerned about high DO's,
running follow-up analyses last two weeks of Oct. Prior to test -sent off effluent for priority
pollutants, completed metals analysis for Sept -no reason for concern there. Waiting for follow-up
results before proceeding further.
5/2/88-letter from City (Earl Weisner,Supt) to George Everett submitting 6 month tox evaluation rport as
requested in 11/87 Administrative letter requiring tox monitoring. They feel they've made adequate
preparations to deal w/ efflu toxicity and noted that 5 consecutive monthly tests have resulted in
LC50 "none". To deal w/ efflu tox, they report: holding effluent chlor resid to 0.2 µg/1 or less,
retained services of treatability consultant to review their tox reduc efforts and to give guidance,
reviewed previous pretreatment 'prelim' analysis,conducted AA analysis for efflu metals and found
to be below water qual criteria conc's,scanned efflu for THM formation and found negligable
conc's,reviewed effluent and in -plant monitoring data for any evidence of upsets,personnel have
attended workshops/talks on efflu tox,have discussed acute and chronic test procedures w/ private
and municipal labs doing those tests. Also included was flow diagram of City's responses to efflu
toxicity. At date of this 5/2/88 letter , Lexington -Regional has draft permit out which includes a
chronic p/f toxicity req w/ Q freq.

1./27/88-Acute tox screens conducted for facility's cooling water outfalls 001 and 005. Resulted in LC50
values 37% and 7.1%. Recent to these results this office had considered acceptable L & M's
proposed change in biocide usage. Considering that in a sense the facility's biocide usage was
corrected. Ken requested the tox group to rescreen this facility in about a month to see if change in
biocide has reduced toxicity.

Noted pre -chlorine detected <0.01 mg/1 and post chlor at 0.6 mg/1. Recommended they contract tox
consultant to develop tox reduction plan.
4/20/88-letter from ARO (Pete Nathanson) to Linville Land re. their submittal of 3/88 test results. Lab had
recorded no LC50 mortality observed but Pete's letter was pointing out that there was observed
mortality but they were less than 50%. His point was that some toxicity still existed and that steps
should be taken to investigate causes. His ideas for potential sources included: RV dump station w/
disinfection chemicals; flushing of antifreeze additives from plumbing of vacant homes; heavy
metals in wastewater;biolog distribution of system organisms; and residual effects from
chlorination of drinking water. Advised that hiring of consultant may become necessary.

1/24/89-memo from L. Gabele to Mouberry allowing facility to perform grab samples for all tox testing
requirements, including chronic. They requested this in a letter dated 1/16/89 because their
discharge occurs from a large lake that serves as a compositing unit.
8/1/88-Arhtur Gillespie of Lithco spoke w/ S. Tedder to agree to WQ compromise of 3/1/91 compliance
date. His attorney will call Legal Affairs to drop ajudication.
7/28/88-memo from S. Tedder to Yvonne Bailey (AG office) passing along Lithco's ajudicatory request
and saying that WQ would agree to modify tox compliance date from 3/89 to 3/1/91. Perrnittee
would monitor monthly til 3/91 when freq would reduce to quarterly. Noted that this proposal had
been informally concurred w/ by Mr. Gillespie of Lithco.
7/1/88-Lithco filed w/ Adminis Hearings for ajudicatory hearing on tox req. in permit. They felt they could
not meet scheduled compliance date in permit of 3/89 due to limitations in draining 1 MGD trtmnt
pond.
5/5/88-letter from S. Tedder to facil telling them that we rcvd their 3/88 results for acute test but that their
permit requires chronic tox monit on a Q freq. Asked that if in the future they do addtl' acute
testing, those results should also be submitted.
4/88- Final report of on -site tox examination performed at Lithium 9/21-9/26/87. Intensive survey
indicated benthic macroinvert communities downstream of facil discharge were seriously impacted.
Based on tox test results, and IWC of 82%, efflu was predicted to be present at conc well above
level demonstated as acutely toxic to Ceriodaphnia and (fthd). At periods of avg rcving stream flow
(IWC 35%), efflu still predicted to cause acute toxicity in aquatic organisms w/ similar or greater
sensitivity than Cerio. Efflu contained signif quantities of lithium and chloride so that LiC1 may/
have contributed to toxic responses recorded in Cerio and fthd minnow. Tot resid chlor
measurements indicate a likely contrib to tox in all on -site bioassays conducted. Efflu sample for
characterization tests however did not contain high tot resid chlorine. Characteriz tests did not
identify organic constsituents as prob. Recomm Lithium cont chr p/f test at 83% as req by permit,
reduce levels of lithium,chloride;and resid chlorine, and a lithium monitoring requirement be
included in permit upon re -issuance.
3/7/88-S. Tedder's memo to A. Mouberry re. Lithium's request for permit modifications. To facility's 5
comments, Tech Services confirmed the following: grab samples from 100 MG pond may be
considered representative and permissible; Final efflu sampling point UT Abernathy Creek is
waters of the State not efflu channel and specifics of discharge point will remain unchanged;
upstream/downstream monit for Cu can be dropped but monthly efflu monitoring must remain;
efflu monit for Be can be dropped; quarterly efflu monit for tot P and tot Nit must remain; whole
effluent tox req must remain unchanged. For tox, the permit requires monthly monit only 'til 3/89
at which time chronic limit at 83% begins w/ Q freq. It is not agreed to defer 83% efflu limitation
until permit expir. and facility's initiation of tox reduc efforts were commended.
2/4/88-submittal by Lithium of 6-month report required per original adminis letter. Report summary:
Summer I987-Lithium performed tox tests on 17 in -plant samples and found 3 wastestreams more
toxic than pond effluent which had LC50 7.5%. 3 wastestreams- hypochlorite scrubber LC50 <5
%(34% of plant flow to pond), LiC1 condensate LC50<5% (14% of plant flow to pond), metal
washout LC50<5 %(7% of plant flow to pond). Chem analysis showed high
chloride,sulfate,lithium,sodium; and available chlorine. Report said chlorine is not considered as
contributing significantly to toxicity however available chlorine levels of >1000 ppm should nor
discount it. ie. Could even the dechlor process add to toxicity of reduced chlorine? Facility did not
cite tox data for lithium although this data is scarce. Citation not given for silver LC50 value which
seems too high for cladocerans. Also no analysis for Ag in wastewater. Regarding quality of test
results, Lithco stated several reasons why their contracted lab results differed with state
results(prep of sampling container, lab tech, "weak' fleas) but does not state which of contracted
labs had these problems. They state that some tox data was unacceptable and they have discont
contact / that lab but which lab?? so can correlate w/ reported data. Also uses term "N C certified
lab" whi h is incorrect for tox analysis at this time. Lithco assumes long time by change in process
37

to reduce toxicity in pond effluent. Projects underway incl modific on hypochlorite circuit using
baghouses to reduce solids that would otherwise go to pond, and evaluating a design to recycle
wash water from metal circuit to reduce salt disch to pond.Recnt permit issue has monitoring then
phase -in of final tox efflu limit.
2/1/88-Lithium (teleph) responded to 1/20/88 letter saying they were aware of high chlorine levels and
were looking at the various chemical forms of the residual. they suspect that it is predominately the
chlorate form which they think, is more toxic.
1/20/88-letter from S. Tedder to Lithium pnting out high chlorine reading in Nov 87 test sample (1.lmg/l)
as potential contribution to toxic effect - LC50 of 20.71%.
Sept 87-Prelim on -site tox testing results: 48 hr Cerio (influ)LC50=.32%;48 hr Cerio(efflu)
LC50=21%;96 hr fthd flow-thru LC50=70%;168 hr Cerio chronic LC50=11%;NOEC=1.0%;
LOEC=10%;ChV=3.2%. IWC=82.7% PF=.615 MGD IWC at avg stream flow 1.7 cfs =
35.9%. This facility has been sent the draft EPA fractionation procedures and have a chemist (Dan
McDonald) working on the tox issue. They are interviewing labs to perform a subset of the
fractionation procedures. Wastewater trtmnt process is a lagoon to treat organic and inorg cmpds in
process wastewater from chem plant( plus domestic).Resid chlorine measured in lagoon efflu
ranged .05-.09 mg/1. High conduct. indicates lrg amts dissolved solids(efflu had high chloride).
Efflu predicted to cause acute toxicity instream during avg stream flows to organisms w/ similar
sensitivity as C. dubia. Referenced benthic survey of 6/10/87-efflu found to cause severe water
qual probs in area.

Yes. Ample area exists for the construction of additional
WWT facilities, if necessary.
8. Topography (relationship to flood plain included): The site
encompasses several hundred acres with varying topography
(3-10% slopes). The WWT pond is located in a surface
drainage feature, however, it appears to be protected from
flooding.
9. Location of Nearest Dwelling: Approx. 1000± feet from the
WWTP site.

10. Receiving Stream or Affected Surface Waters: U. T. to
Abernathy Creek
a. Classification: C
b. River Basin and Subbasin No.: Catawba 030837
c. Describe receiving stream features and pertinent
downstream uses: Flow observed in the receiving stream
at the point of discharge. Downstream uses are
primarily agriculture. No other dischargers are known
for a reasonable distance downstream.
PART II - DESCRIPTION OF DISCHARGE AND TREATMENT WORKS
1. a. Volume of Wastewater: 0.615 MGD (Design Capacity)
b. What is the current permitted capacity: 0.615 MGD
c. Actual treatment capacity of current facility (current
design capacity): 0.615 MGD
d. Date(s) and construction activities allowed by previous
ATCs issued in the previous two years: N/A
e. Description of existing or substantially constructed
WWT facilities: The existing WWT facilities consist of
one 0.005 MGD "package type" WWTP and one 0.010 MGD
"package type" WWTP both having screening, aeration
(diffused), and clarification. These facilities are
followed by an industrial WWT lagoon with pH
neutralization. No disinfection is provided.
f. Description of proposed WWT facilities: N/A
g. Possible toxic impacts to surface waters: Toxicity
limit became effective in January, 1996. The initial
toxicity test conducted in January was a pass. Facility
had an inconsistent history of passing their toxicity
tests prior to 1/96.
h. Pretreatment Program (POTWs only): Not Needed.
2. Residual handling and utilization/disposal scheme: Residuals
are removed from the treatment pond and stockpiled on -site.
These solids are used throughout the site to fill uneven
terrain and stabilize roads. Residuals from the two (2)
package plants are removed and taken to Bessemer City's WWTP
for disposal.
3. Treatment Plant Classification: Class II (no change from
previous rating).
4. SIC Code(s): 2819, 2869 Wastewater Code(s): 32, 31, 02
5. MTU Code(s): 50000

PART III - OTHER PERTINENT INFORMATION
1. Is this facility being constructed with Construction Grant
Funds or are any public monies involved (municipals only)?
No
2. Special monitoring or limitations (including toxicity)
requests: None at this time.
3. Important SOC/JOC or Compliance Schedule dates: N/A
4. Alternative Analysis Evaluation: There are no on -site or
off -site alternatives currently available which would
eliminate the need to discharge.
PART IV - EVALUATION AND RECOMMENDATIONS
The permittee, FMC Corporation, Lithium Division (FMC),
requests renewal of the subject Permit. There have been no
changes in the existing treatment components since the Permit was
last renewed, however, FMC has requested changes to the Permit
during this renewal.
FMC is requesting that the existing stormwater outfalls,
presently covered in Permit No. NCS000002 be incorporated into
the process water discharge NPDES Permit (NC0005177). FMC also
requests that the permitted flow rate be increased from 0.615 MGD
to 0.700 MGD. This increase will aid in the removal of the water
from the lower pond (outfall 001) during periods of wet weather.
The company has future plans to construct a pilot plant on newly
acquired property west of Hwy. 161. Waste streams expected from
the pilot plant include: stormwater, boiler blowdown, cooling
water, and steam condensate. The discharges will enter the storm
drainage system and ultimately discharge through outfall 004.
Pending receipt and approval of the WLA and concurrence by
the TSB on the changes/modifications requested by FMC in this
renewal, it is recommended that the Permit be renewed as
requested.

- Drainage from the Toe Drain of the Lower Pond Dam
FMC currently has one restroom which is connected to the city of
Bessemer City Municipal treatment works. This sanitary facility
supplies 3-5 employees and discharge to the Bessemer City
treatment works from this facility is negligible. Nonetheless,
FMC is exploring directing all sanitary wastes to the Bessemer
City municipal system at some future date. This would increase
the discharge to a sanitary wastewater transport system to
approximately' 12-15 K gal/day.

Re: FMC Corporation Lithium Division
Bessemer City Manufacturing Facility
NPDES Stormwater/Wastewater Permits
NCS000002/NC0005177
Dear Ms. Sullins:
fMC
FEB 1 T
wATER
SEC, • kN
'FEB 5 19
Thank you for taking the time to meeting with Barbara Ritchie and
me concerning the NPDES permitting for FMC Corporation's Lithium
Division facility in Bessemer City ("FMC"). As a result of the
meeting, FMC better understands the issues raised in the Division
of Environmental Management ("DEM") November 6, 1995 letter, over
your signature, and believes that the DEM more fully understands
FMC's questions as enumerated in FMC's December 15, 1995 letter.
Specifically, pursuant to our December 18 meeting, FMC
understands that the following clarifications and actions have
been agreed upon:
1. In evaluating alternative permitting scenarios, as discussed
in the August 15, 1995 report Evaluation of Stormwater and
Regulated Discharges, FMC understands that the 2B .206 rules
for zero flow streams would prevent any increase in oxygen
consuming wastes and ammonia -nitrogen if an effluent channel
were designated with a discharge point downstream of the
confluence of outfall 001, as designated in NPDES Permit No.
NC0005177, and outfall 004, as designated in NPDES stormwater
permit No. NCS000002. While this permitting scenario is not
likely to be selected, future expansion of oxygen -consuming
discharges could be permitted with commensurate reductions in
existing loadings.

Ms. Coll en Sullins
DEM Permits and Engineering
January 9, 1996
Page 2
2. FMC's system of channels and canals which discharge via
outfall 004, as designated in NPDES Stormwater permit No.
NCS000002, is a stormwater conveyance system whose flows are
considered in determining a dilution factor appropriate for
assigning limits at outfall 001, as enumerated in NPDES Permit
No. NC 005177.
3. As discussed in the report "Evaluation of Stormwater and
Regulated Discharges," which FMC submitted to DEM on August
15, 1995 pursuant to the requirements of NPDES Stormwater
Permit No. NCS000002, FMC has conducted additional
investigation and advised DEM that cooling and boiler waters
are al o discharged via outfall 004. Further, as also
discussed in that report, waters collected in the toe drain of
the Lower Pond Dam are discharged to the unnamed tributary.
These additional flows will be further characterized in the
renewal application for NPDES permit No. NC0005177 to be
submitted by March 30, 1996, with a request to combine the two
NPDES ermits and clarify the status of the toe drain.
4. FMC reviewed the proposal currently in internal review
project
for development of a pilot plant on some newly acquired
property west of Hwy 161. As discussed, it is FMC's intention
to gracle the site to drain to FMC's existing stormwater system
along combining the small quantity of boiler blowdown and
cooling water from the unit to that from the other FMC
facility west of Hwy 161 which discharges to the same system.
These lows will also be covered with the renewal application
for NP ES permit No. NC0005177 in March.
5. The ch nges to the statistical evaluation for chronic bioassay
compliance were discussed. FMC had reviewed the results of
voluntary bioassay testing conducted downstream of the
conflu nce of outfall 001 and outfall 004, as summarized in
FMC's tecember 15, 1995 letter. Mr. Matt Matthews volunteered
to review the three instances where a chronic value of 88% was
report d to see if a 90% threshold rate would be achieved with
the ne statistical analysis. A copy of the laboratory
report are enclosed with his copy of this letter. FMC
appreciates his assistance in this matter.

Ms. Colleen Sullins
DEM Permits and Engineering
January 29, 1996
Page 3
6. NPDES permit No. NC0005177 allows for alternate flow rates to
correspond to alternate chronic bioassay dilution factors
which should read as follows:
Flow rate (MGD) Dilution factor
0.500 - 0.615 78%
0.400 - 0.500 74%
0.300 - 0.400 70%
0.100 - 0.300 63%
<0.100 36%
7. FMC is reviewing its historic work conducted to identify and
control factors which affect the bioassey results for its
effluent samples. As discussed with DEM, based on that work,
FMC had been successful in achieving bioassay passes at 78%
during 1994, however, given very similar effluent conditions,
1995 results were much less favorable.
FMC again thanks DEM for their assistance in this matter and
looks forward to continuing discussions on these issues and the
selection of a course of action amenable to both parties.
If you have any questions, please contact Barbara Ritchie at
704/868-0806, or in her absence, me at 704/868-0849.
Very truly yours,
