A. (3.) CHRONIC TOXICITY PERMIT LIMIT (Quarterly)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Ceriodaphnia dubia at an effluent concentration of 78%.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in
the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or
subsequent versions or "North Carolina Phase 11 Chronic Whole Effluent Toxicity Test Procedure"
(Revised-February 1998) or subsequent versions. The tests will be performed 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.
If the test procedure"performed as the first test of any single quarter results in a failure or ChV below the "
permit limit, then multiple-concentration testing shall be performed at a minimum, in each of the two
following months as described in "North Carolina Phase 11 Chronic Whole Effluent Toxicity Test
Procedure" (Revised-February 1998) or subsequent versions.
The chronic value for'multiple concentration tests will be determined using the geometric mean of the
highest concentration having no detectable impairment of reproduction or survival and the lowest
concentration that does have a detectable impairment of reproduction or survival. The definition of
"detectable impairment," collection methods, exposure regimes, and further statistical methods are
specified in the "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised-
February 1998)or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR-]) for the months in which tests were performed, using the parameter
code TGP3B for the pass/fail results and THP3B for the Chronic Value. Additionally, DWQ Form AT-3•
(original) is to be sent to the,following address:
Attention: NC DENR/DWQ/Environmental Sciences Section
1621 Mail Service Center

Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section no later
than 30 days after the end of the reporting period for which the report is made.
Test data shall be complete, accurate, include all supporting chemical/physical measurements and all
concentration/response data, and be certified by laboratory supervisor and ORC or approved designate
signature. Total residual chlorine of the effluent toxicity sample must be measured and reported if
chlorine is employed for disinfection of the waste stream.
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 Section at the address cited above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required, monitoring
will be required during the following month.

B. (1.) FINAL LIMITATIONS AND CONTROLS
During the period beginning on the effective date of the permit and lasting until expiration, the permittee
is authorized to discharge stormwater from Outfall 004. Such discharges shall be controlled, limited and
monitored as specified below:
STORMWATER POLLUTION PREVENTION PLAN
The permittee shall develop and continue to update a Stormwater Pollution Prevention Plan (SPPP),
herein after referred.to as the Plan. The Plan.shall be considered public information and shall include, at
a minimum,the following items:
1. Site Plan. The site plan shall provide a description of the physical facility and the potential
pollutant sources which may be expected to contribute to contamination of stormwater
discharges. The site plan shall contain the following:
(a) A general location map (USGS quadrangle map or appropriately drafted equivalent map),
showing the facility's location in relation to transportation routes and surface waters, the
name of the receiving water(s) to which the stormwater outfall(s) discharges, or if the
discharge is to a municipal separate storm sewer system, the name of the municipality
and the ultimate receiving waters, and accurate latitude and longitude of the point(s) of
discharge. The general location map (or alternatively the site map) shall identify whether
each receiving water is impaired (on the state's 303(d) list of impaired waters) or is
located in a watershed for which a TMDL has been established, .. and what the
parameter(s) of concern are.
(b) A narrative description of storage practices, loading and unloading activities, outdoor
process areas, dust or particulate generating or control processes, and waste disposal
practices. A narrative description of the potential pollutants which could be expected to
be present in the stormwater discharge from each outfall.
(c) A site map drawn to scale (including a distance legend) showing: the site property
boundary, the stormwater discharge outfalls, all on-site and adjacent surface waters and
wetlands, industrial activity areas (including storage of materials, disposal areas, process
areas, loading and unloading areas, and haul roads), site topography, all drainage features
and structures, drainage areas for each outfall, direction of flow in each drainage area,
industrial activities occurring in each drainage area, buildings, existing BMPs, and
impervious surfaces. The site map must indicate the percentage of each drainage area
that is impervious.
(d) A list of significant spills or leaks of pollutants that have occurred at the facility during
the three (3)previous years and any corrective actions taken to mitigate spill impacts.
(e) Certification that the stormwater outfalls have been evaluated for the presence of non-
stormwater discharges. The certification statement will be signed-in accordance with the
requirements found in Part H,, Standard Conditions, Section B, Paragraph 11. The
Part 1, Section B
Page 4.of 4 2 . ,

5
Part I, Section B Permit NCO005177
permittee shall re-certify annually that the' p fy y stormwater outfalls have-been evaluated for
the presence of non-stormwater discharges.
2. Stormwater Management Plan. The stormwater management plan shall contain a narrative
description of the materials management practices employed which control or minimize the
exposure of significant materials to stormwater, including structural and nonstructural measures.
The stormwater management plan, at a minimum, shall incorporate the following:
(a) Feasibility Study. A review of the technical and economic feasibility of changing the
methods of operations and/or storage practices to eliminate or reduce exposure of
materials and processes to stormwater. Wherever practical, the permittee shall prevent
exposure of all storage areas, material handling operations, and manufacturing or fueling
operations. In areas where elimination of exposure is not practical, the stormwater
management plan shall document the feasibility of diverting the stormwater runoff away
from areas of potential contamination.
(b) Secondary Containment Requirements and Records. Secondary containment is required
for: bulk storage of liquid materials; storage in any amount of Section 313 of Title III of
the Superfund Amendments and Reauthorization Act (SARA) water priority chemicals;
and storage in any amount of hazardous substances, in order to prevent leaks and spills
from contaminating stormwater runoff. A table or summary of all such tanks and stored
materials and their associated secondary containment areas shall be maintained. If the
secondary containment devices are connected to stormwater conveyance systems, the
connection shall be controlled by manually activated .valves or other similar devices
(which shall be secured closed with a locking mechanism), and any stormwater that
accumulates in the containment area shall be at a minimum visually observed for color,
foam, outfall staining, visible sheens and dry weather flow, prior to release of the
accumulated stormwater. Accumulated stormwater shall be released if found to be
uncontaminated by any material. Records documenting the individual making the
observation, the description of the accumulated stormwater, and the date and time of the
release shall be kept for a period of five years.
(c) BMP Summary. A listing of site structural and non-structural Best Management
Practices (BMP) shall be provided. The installation and implementation of BMPs shall
be based on the assessment of the potential for sources to contribute significant quantities
of pollutants to stormwater discharges and data collected through monitoring of
stormwater discharges. The BMP Summary shall include a written record of the specific
rationale for installation and implementation of the selected site BMPs. The BMP
Summary shall be reviewed and updated annually.
3. Spill Prevention and Response Plan. The Spill Prevention and Response Plan (SPRP) shall
incorporate'an assessment of potential pollutant sources based on a materials inventory of the
facility. Facility personnel (or the team) responsible for implementing'the SPRP shall be
identified in a written list incorporated into the SPRP and signed and dated by each individual
acknowledging their responsibilities for the plan. A responsible person shall be on-site at all
times during facility operations that have the potential to contaminate stormwater runoff through
spills or exposure of materials associated with the facility operations. The SPRP must be site
stormwater specific. Therefore, an oil Spill Prevention Control and Countermeasure plan
(SPCA may be a component of the SPRP, but may not be sufficient to completely address the
Part l,.Section B
Page 2 of 12

r
Part I, Section B Permit NC0005177
stormwater aspects of the SPRP. The common elements of the'SPCC with the Sl'RP may be
incorporated by reference into the SPRP.
4. Preventative Maintenance and Good Housekeeping Program. A preventative maintenance and
good housekeeping program shall be developed. The program shall list all stormwater control
systems, stormwater discharge outfalls, all on-site and adjacent surface waters and wetlands,
industrial activity areas (including material storage areas, material handling areas, disposal areas,
process areas, loading and unloading areas, and haul roads), all drainage features and structures,
and existing structural BMPs. The program shall establish schedules of inspections,
maintenance, and housekeeping activities of stormwater control systems, as well as facility
equipment, facility areas, and facility systems that present a potential for stormwater exposure or
stormwater.pollution. ..Inspection of material handling areas. and regular cleaning schedules of.
these areas shall be incorporated into the program. Timely compliance with the established
schedules for inspections, maintenance, and housekeeping shall be recorded in writing and
maintained in the SPPP.
5. Employee Training. Training programs shall be developed and training provided at a minimum
on an annual basis for facility personnel with responsibilities for: spill response and cleanup,
preventative maintenance activities, and for any of the facility's operations that have the potential
to contaminate stormwater runoff. Facility personnel (or team) responsible for implementing the: '
training shall be identified, and their annual training shall be documented by the signature of
each employee trained.
6. Responsible Party. The Stormwater Pollution Prevention Plan shall identify a specific
position(s) responsible for the overall coordination, development, implementation, and revision
to the Plan. Responsibilities for all components of the Plan shall be documented and position
assignments provided.
7. Plan Amendment. The permittee shall amend the Plan whenever there is a change in design,
construction, operation, or maintenance which has a significant effect on the potential for the
discharge of pollutants to surface waters. All aspects of the Stormwater Pollution Prevention
Plan shall be reviewed and updated on an annual basis. The annual update shall include an
updated list of significant spills or leaks of pollutants for the previous three years, or the notation
that no spills have occurred. The annual update shall include written re-certification that the
stormwater outfalls have been evaluated for the presence of non-stormwater discharges. Each
annual update shall include a documented re-evaluation of the effectiveness of the BMPs listed
in the BMP Summary of the Stormwater Management Plan.
The Director may notify the permittee when the Plan does not meet one or more of the minimum
requirements of the permit. Within 30 days of such notice, the permittee shall submit a time
schedule to the Director for modifying the Plan to meet minimum requirements. The permittee
shall provide certification in writing (in accordance'with Part II, Standard Conditions, Section B,
Paragraph 11) to the Director that the changes have been made.
8. Facility Inspections. Inspections of the facility and all stormwater systems shall occur as part of
the Preventative Maintenance and Good Housekeeping Program at a minimum on a semi-annual
schedule, once during the first half of the year(January to June), and once during the second half
(July to December), with at least 60 days separating inspection dates (unless performed more
Part 1, Section B
Page 3 of 12 `

Part I, Section B Permit NCO005177
frequently than semi-annually). These facility inspections are different from,,and-in addition to,
the stormwater discharge characteristic monitoring required in Part 1, Section B..(2.). ..
9. Implementation. The permittee shall implement the Plan. Implementation of the Plan shall
include documentation of all monitoring, measurements, inspections, maintenance activities, and
training provided to employees, including the log of the sampling data and of actions taken to
implement BMPs associated with the industrial activities, including vehicle maintenance
activities. Such documentation shall be kept on-site for a period of five years and made available
to the Director or the Director's authorized representative immediately upon request.
B. (2.) MINIMUM MONITORING AND REPORTING REQUIREMENTS
1. Analytical monitoring of stormwater discharges shall be performed as specified in Table 1. All
samples shall be collected from a discharge resulting from a representative storm event. The
required monitoring will result in a minimum of ten analytical samplings being conducted over
the term of the permit at each stormwater discharge outfall (SDO).
A representative storm event is a storm event that measures greater than 0.1 inches of rainfall.
The time between this storm event and the previous storm event measuring greater than 0.1
inches must be at least 72 hours. A single storm event may have a period of no,precipitation of
up to 10 hours. For example, if it rains but stops before producing any collectable discharge, a
sample may be collected if the next rain producing a dischar a be gins within 10 hours.
2. ff the stormwater is controlled by a detention pond, and that pond discharges only in response to
a storm event exceeding a 25-year, 24-hour storm, the pond shall be considered a non-
discharging stormwater control system-and not subject to NPDES requirements, unless the
discharge causes a violation of water quality standards.
3. Stormwater samples analyzed in accordance with the terms of this permit shall be submitted on
forms provided by the Director no later than March 1 following the year in which sampling was
required to the DWQ Central Office. Stormwater samples analyzed in accordance with the terms
of this permit shall be submitted to the Division on Discharge Monitoring Report forms provided
by the Director. The permittee shall also submit an Annual Summary Data Monitoring Report to
the appropriate DWQ Regional Office (RO) by March I of each year. The submittal shall be on
forms supplied by the Division. Addresses for each RO can be found here:

3. If no discharge occurs during the sampling period, the permittee is required to record "No
Plow"on a monthly monitoring report to comply with reporting requirements.-
4. Maintain a record of the Tier Two response in the Stormwater Pollution Prevention Plan.
During the term of this permit, if the valid sampling results required for the permit monitoring
periods exceed the benchmark value, or are outside the benchmark range, for any specific parameter
at any specific outfall on four occasions, the permittee shall notify the DWQ Regional Office
Supervisor in writing within 30 days of receipt of the fourth analytical results. DWQ may but is
not limited to:
require that the permittee revise, increase, or decrease the monitoring frequency for the
remainder of the permit;
• require the permittee to install structural stormwater controls;
require the permittee to implement other stormwater control measures; or
• require that the permittee implement site modifications to qualify for the No Exposure
Exclusion.
6. if a facility is required to sample multiple stormwater discharge locations, the permittee may
petition the Director to sample at a reduced number of outfalls. These outfalls would be granted
"Representative Outfall Status" (ROS). DWQ may grant Representative Outfall Status if
discharges from a single outfall are representative of discharges from multiple outfalls.
Approved ROS will reduce the number of outfalls where anal3qical sampling requirements apply.
Qualitative observations shall be recorded for all outfall locations.
7. This site discharges to impaired waters experiencing problems with biological integrity (North
Second Creek) and excessive nutrient loading (High Rock Lake watershed). If a Total
Maximum Daily Load (TMDL) is approved for this segment of North Second Creek or High
Rock Lake, the permittee may be required to monitor for the pollutant(s) of concern in the future
and submit results to the Division of Water Quality. The Division will consider the monitoring
results in determining whether additional BMPs are needed to control the pollutant(s) of concern
to the maximum extent practicable.
If additional BMPs are needed to achieve the required level of control, the permittee will be
required to (1) develop a strategy for implementing appropriate BMPs, and (2) submit a
timetable for incorporation of those BMPs into the permitted Stormwater Pollution Prevention
Plan.

BACKGROUND
FMC Corporation owns and operates a manufacturing facility west of Bessemer City, NC that
produces lithium compounds, organic and inorganic. Lithium is currently received as lithium
carbonate and converted to various commodities. Because of the safety issues involved
with lithium compound manufacturing the plant is divided and isolated into two separate
operations, organic production and inorganic product. The domestic waste from this facility
is collected and sent to the local POTW, Bessemer City.
This permit contains conditions and requirements for industrial-based wastewater and
stormwater. Because of the various wastewater characteristics, plant operations, and
sources, Outfall 001 is designated as the primary industrial wastewater discharge and has a
permitted flow. Outfall 004 is primarily a stormwater discharge with traces of intermittent
industrial sources.
COLLECTION AND OPERATION
The condensate,•boiler blowdown, and stormwater, and stormwater produced by the organic
operation is sent to the Research & Development (R&D) pond. The R&D pond also collects
stormwater from the surrounding area of the labs, roof drains, and other inorganic process
areas, and is normally transferred into the plant process wastewater collection system. if

required the R&D pond can be transferred either to the local POTW or diverted into the
stormwater conveyance channel.
The plant process wastewater system collects wastewater from the R&D pond, lithium
hypochlorite scrubber, two reverse osmosis filtration systems, cooling tower blowdown,
boiler blowdown, condensate, once-through cooling water, drains, process wastewater, and
stormwater. After the majority of wastewater sources are collected, the pH is measured and
sulfuric acid is added as needed. Additional miscellaneous small volumes of condensate and
boiler blowdown combined after the pH adjustment. The wastewater continues through an
open channel to the lower 24 acre retention pond. As needed the retention pond is set up to
siphon wastewater via a manually adjusted flow to a flow weir box that discharges to Outfall
001.
The scrubber wastewater stream is treated with hydrogen peroxide to convert the
hypochlorite to chloride. The two reverse osmosis units provide filtration to removed metals
by recycling the high total dissolved solids waste stream and discharging the relatively clean
water as wastewater.
The stormwater/wastewater that enters the stormwater conveyance channel enters a
sedimentation pond, continues to another polishing pond, and is then discharged from
Outfall 004. A calibrated weir is available to monitor Outfall 004 flow. If needed the
sedimentation pond flow can be diverted to the lower 24 acre retention pond.
The discharge from Outfall 004 continues down a concrete channel, mixes with Outfall 001,
and discharges into an unnamed tributary to First Creek.
HISTORY
The original facility included a lithium ore processing section which required the application
of federal categorical effluent limits. After 2003, the ore processing section was shut down
and the facility started receiving lithium carbonate. Consequently, the federal-based criteria
no longer applied but the federal-based TSS limits were continued. The permit issued in
2003 removed Outfall 001 flow tiers effluent pages for 0.700 MGD and 0.800 MGD, removed
chromium monitoring, and removed instream monitoring. In 1999, the facility ceased
operation of its internal domestic treatment plant and diverted all its domestic waste to the
regional Bessemer City WWTP.
In 2006, quarterly monitoring for magnesium was added to Outfall 001 as a pollutant of
interest for future evaluation, and quarterly monitoring of zinc and silver were removed.
Also, in 2006 quarterly monitoring for ethylbenzene and methyl chloride were added to
Outfall 004 as pollutants of interest for future evaluation.
COMPLIANCE HISTORY
Since 2006 there were 11 measurement frequency violations, 2 failed toxicity tests, and 1
permitted flow exceedance. No fines were incurred.
PERMITTING STRATEGY - WASTEWATER
Secondary Treatment Standards (Outfall 001)
Since no federal-based guidelines apply and the previous federal-based T55 limits are still in
the permit, a comparison to the secondary standards was conducted to determine the more
stringent limits:
Permitted flow = 0.615 MGD
Secondary standard, monthly average maximum = 30.0 mg/L
Secondary standard, daily maximum = 45.0 mg/L
Conversion factor for Ibs = 8.34
Current permit daily average maximum limit = 1001.7 Ibs/day
Current permit monthly average maximum limit = 333.9 Ibs/day
1) Permitted flow (MGD) x 8.34 x secondary standard (mg/L) = Ibs
2) 0.615 MGD x 8.34 x 30.0 mg/L = 153. 87 Ibs/month
3) 0.615 MGD x 8.34 x 45.0 mg/L = 230.81 lbs/day

4) The secondary standard limits are more stringent and must be applied
Note: Based on DMRc data the more stringent limit should not be an issue.
Ammnni� Tnv rit /Pry L4.r7.7 Source (Outfall fl(11)
/"111 i111V 111u iVA�t 1� IV11 VV1
Ammonia monitoring was established in the original permit when it also contained domestic
wastewater, the domestic source was removed from the influent in 1999. Further
investigation indicated no ammonia is added or generated in the plant operation and the
reported ammonia data supports no significant ammonia source or effluent residuals.
Therefore, ammonia monitoring will be removed. (�(►
Reasonable POtaiitiwl An;IysEs (PAPA) (Ou4i uil vvi Outfall ilV4)
The Division conducted EPA-recommended analyses to determine the reasonable potential
for toxicants to be discharged by this facility, based on DMR data from June 2007 to May
2010 and from the Priority Pollutant Analysis (PPA) submitted with the renewal application.
Evaluations were conducted for chlorides on both outfalls, and methyl chloride and
ethylbenzene for outfall 004. Magnesium was not evaluated by the RPA process since it was
determined it had no applicable WQS, thus monitoring will be removed.
Results suggested reasonable potential for the facility to exceed the chlorides action level
standard from outfall 001. Per policy as an action level parameter, quarterly monitoring will
be applied. Even through chlorides did not show reasonable potential in outfall 004, as a
pollutant of interest its monitoring will continue on a quarterly basis. Both methyl chloride
and ethylbenzene RPA evaluations did not show reasonable potential, per policy, monitoring
will be removed.
Whole Effluent Toxicity (Outfall 001)
The permit has a chronic toxicity limit using ceriodaphnia dubia, at 78% effluent
concentration. Since June 2007 the facility conducted 15 toxicity tests, failed 2. Chronic
toxicity testing will remain in the permit. The most current special condition narrative will be
implemented.
Priority Pollutant Analysis (Outfall 001)
Evaluation of the PPA was conducted. The single mercury and single selenium data was
inconclusive in supporting no concerns. Therefore, for the next permit renewal cycle the PPA
submitted must use EPA test Method 1631E for mercury, or equivalent, and an EPA test
method with a minimum measurement limit of 5 pg/I for selenium. The reported data will be
evaluated in the next renewal.
Narratives Evaluation (Outfall 004)
Several redundant narratives and conditions will be removed from outfall 004 effluent page
that are covered by the stormwater requirements in Section B.
PERMITTING STRATEGY - STORMWATER
Outfall 004 is operated as the plant stormwater discharge. The stormwater permitting group
provided the most current narrative and conditions to apply in this renewal under Section B.
Because toluene is stored in the organic plant, it is a pollutant of interest for stormwater and
will be added to the stormwater monitoring requirements. If any questions or concerns arise
Robert Patterson, engineer in the stormwater permitting group, would be the point of
contact.
SUMMARY OF PROPOSED CHANGES
In keeping with Division policies the following will be incorporated into the permit:
• Outfall 001: TSS effluent limits revised/reduced.
• Outfall 001: ,ammonia effluent monitoring removed.
• Outfall 001: Magnesium effluent monitoring removed.
• Outfall 001: Total chloride effluent monitoring reduced to quarterly.
• Outfall 001: Chronic toxicity special condition narrative revised.
• Outfall 004: Total chloride effluent monitoring reduced to quarterly.
• Outfall 004: Methyl chloride effluent monitoring removed.
• Outfall 004: Ethylbenzene effluent monitoring removed.

Subject: Questions about process
Rodney,
I have some additional questions about the FMC process.
1) How is the toluene listed under outfall 004 stored? Does it have secondary containment?
Yes we store toluene in Bulk storage tank with secondary containment.
2) Per your flow sheet,the lithium hypochlorite scrubber generates about 100 gpm when operating. Your flow
schematic indicates hydrogen peroxide is added to the lithium hypochlorite waste stream. Explain what the
addition of hydrogen peroxide does to this stream. If it converts all the excess hypochlorite to chloride then
what other than manual sampling is in place to insure this occurs?
The addition of Hydrogen Peroxide is added to convert hypochlorite to chloride, water and oxygen as you
noted. The addition of Hydrogen peroxide is presently controlled by incorporating a hydrogen peroxide sensor
and ORP meter.
Thanks for your assistance.

Here is what Nikki sent me for methyl chloride and ethylbenzene. FMC's data is way below these numbers, so I'm going
to recommend dropping them from the sw outfall monitoring.

Ni Robert,
We have a limited data number for methyl chloride (CAS#74-87-3)of 275 mg/L LD (FW aquatic life% FAV). This is very
LD as there is only a single data point available.
Ethylbenzene (CAS# 100-41-4) has a good amount of data available. The freshwater benchmark would be 970 ug/L.

Nikki,
I'm working on a renewal of a permit that didn't have benchmarks in the last term. It had monitoring for Ethylbenzene
and Methyl Chloride. Can you see if there is enough data to develop a benchmark for these? Most of the sampling
submitted was<5 ug/I; but I'm not sure what number I should be looking for. The permittee wants to drop these from
monitoring.
Thanks!

Subject: FMC Lithium/NC0005177 Renewal
Hi Ron,
I enjoyed talking with you on Friday. As a follow-up to that conversation, I am sending you a few notes on the inspection
I just performed. The questions I have are as follows:
1. FMC Lithium does not have a monitoring requirement for lithium. A near by facility (Chemetall Foote/NC0033570) also
processes lithium from South America, but they have a monitoring requirement. The analytical test for lithium also now
requires'lab certification to perform/report. Should lithium monitoring be required at this facility?
2. The facility is discharging wastewater from a stormwater pipe,(outfall 004) Normally boiler blowdown/non-contact
cooling water requires a general wastewater permit.
3. The air scrubber is being expanded/improved. Where does the NOX discharge go, and is it a problem?
4. Can we change the pounds per day to concentration based? It is a license to pollute. (Not that FMC is having
problems with it... the pounds per day limits are just ridiculously high/outdated limits). Sorry a little venting going on
there.. :)
For SW:
1. The outfalls have not been certified for non-stormwater discharge. The outfalls have been investigated for non sw
discharge, but not tracked or with a signed certification. Isn't this now required annually? (couldn't find the'annual'
requirement in their sw section of the permit) And BTW..they have a permitted non-sw discharge at this outfall. What
problems does this raise and how do they certify this?
2.They are not using 'the official form' for qualitative monitoring (not required yet). I think there was a movement
toward requiring facilities to use the form in the effort for consistency?
3. SPPPlan updates for AST tank addition. Are they necessary?The facility had a question about it.
Let me know if you have any questions.
anks any advice!!

PART IV - EVALUATION AND RECOMMENDATIONS
The FMC Corporation, Lithium Division NPDES permit is under review for renewal of their
discharge permit. The systems were observed to be in good working order at the time of the field
review. At the time of the site visit there was significant flow at the outfall due to heavy rainfall.
There are groundwater remediation well throughout the plant site. These wells are covered under
NC Hazardous Water Section NCD000771964.
This permit combines a wastewater permit with an industrial stormwater permit. MRO
recommends that the permit be reviewed for consistency with the most recent stormwater testing,
observation, and permit requirements.
The facility has collected and submitted analytical data and requests that ethyl benzene and
methyl chloride be removed from the permit.
MRO recommends that the permit be ren wed.

CO Stormwater Review Summary:
1, General Observations:
• Outfall 001 —all-s"v
• Outfall 004--sw and cooling water(use a biocide/additive)
2. Impairment: TMDL for fecal coliform(2004) for Crowders Creek watershed. Fecal coil form is not a pollutant of
concern in sw(due to industrial activities)at this particular facility. The 2004 basinwide plan states that
urbanization is the largest contributor to the impairment of Crowders Creek. Abernethy Creek was on the 2008
303d list- impaired biological integrity; but is removed on the draft 2010 list. The facility drains to First Creek,
then to Abernethy, and on into Crowders Creek. The 2010 basinwide plan states that Abernathy Creek is a
"success" for improved long-term water quality. This is in part due to major upgrades at this facility.
3. Threatened and Endangered: No federal T&E species identified.
4. Location: The previous permit stated that the facility discharged to a UT to Abernethy Creek. However,based on
current GIS stream data and USGS map,it appears that it should be UT to First Creek,which then drains to
Abernethy Creek.
5. Industrial Changes Since Previous Permit: Added a stormwater control pump in the R&D pond(contributing id-1 I
in renewal application. This is part of the system that drains to the ww outfall 001,not the stormwater outfall 004.
6. Analytical Monitoring Notes: The EPA MSGP(2008)has monitoring for Total Aluminum,Total Iron, and Nitrate
+Nitrite. NC will be dropping the strewn standard for Iron, so it is not recommended to be included with this
permit. Aluminum and N+N are not potential pollutants,so they are not recommended to be included in the
monitoring.
Toluene is listed as a potential pollutant of outfall 004 in the renewal application. No sampling data for this is
available from this outfall, so it is recommended to be added to the monitoring of outfall 004 to get some data for
it. It will be compared to the current sw benchmark for non-trout waters(0.055 mgA).
The current parameters at outfall 004 are TSS,pH,conductivity,chloride,ethyl benzene,and methyl chloride. The
facility did sampling for ethyl benzene and methyl chloride,and requested that they be removed from monitoring
requirements since all results were below the detection limit. Ethyl ben7cne and methyl chloride are recommended
to be removed from the monitoring requirements.
7. Qualitative Monitoring Notes: Qualitative monitoring was performed with no items of concern noted.
Revised Permit Recommendations: Analytical Monitoring:
1. Ethyl benzene and methyl chloride will be removed. Toluene will be added with a benchmark.
2_ All analytical monitoring has been set to semi-annually during a representative storm event as defined in Part 11
Section B. The permittee must also document the total precipitation for each event. If no discharge occurs during
the sampling period,the permittee must submit a monitoring report indicating"No Flow"within 30 days of the end
of the six-month sampling period. Additionally,samples must be taken a minimum of 60 days apart,as specified
in Table 2.
3. Benchmarks for analytical monitoring have been added to this draft permit. Exceedances of benchmark values
require the permittee to increase monitoring, increase management actions,increase record keeping, and/or install
stormwater Best Management Practices(BMPs)in a tiered program. If the sampling results are above a
benchmark value,or outside of the benchmark range, for any parameter at any outfall then the facility shall follow
the Tier I guidelines which require a facility inspection within two weeks and implementation of a mitigation plan
within two months. If during the term of this permit,the sampling results are above the benchmark values,or
outside of the benchmark range,for any specific paramcter at a specific discharge outfall two times in a row
(consecutive),then the facility shall follow the Tier 2 guidelines which require a repetition of the steps listed for
Tier I and also immediately institute monthly monitoring for all parameters at every outfall where a sampling result
Page 3 of 5

-NC9005177 ,
exceeded the benchmark value for two consecutive samples.
4. The permittee is required to collect all of the analytical and qualitative monitoring samples during representative
storm events as defined in Part 11 Section B. Qualitative monitoring is required regardless of representative outfall
status.
5. The permittee is responsible for all monitoring until the renewal permit is issued. See Footnote I of Tables 1,4,
and 5.
6. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall parameter is in this
permit,however.)
T Vehicle maintenance monitoring has been revised to semi-annually in order to coincide with analytical and
qualitative monitoring.
Other Proposed Changes to the Previous Permit:
1. Additional guidance is provided about the Site Plan requirements. The site map must now identify if the receiving
stream is impaired and if it has a TMDL established. It must also describe potential pollutants in each outfall. The
map requirements are stated more explicitly. And,the site plan must contain a list of significant spills that have
occurred in the past three years and also must certify that the outfalls have been inspected to ensure that they do not
contain non-stormwater discharges. Additional information is provided in Part lI Section A.
2. Additional requirements for the Stormwater Management Plan have been specified in Part Il Section A. More
details regarding secondary containment are provided.
3. Additional requirements for the Stonnwater Pollution Prevention Plan have been specified in Part 11 Section A.
The plan must also be updated annually to include a list of significant spills and to certify that the outfalls do not
contain non-stormwater discharges.
4. The facility must now implement a semi-annual Facility Inspection Program of the site's stormwater management
controls as specified in Part It Section A.
5. Information regarding the No Exposure Exclusion has been added to this draft permit. If industrial materials and
activities are not exposed to precipitation or runoff as described in 40 CFR§122.26(g),the facility may qualify for
a No Exposure Exclusion from NPDES stormwater discharge permit requirements. Additional information is
provided in Part I Section A.
Discussions with permittee: Performed a site visit on August 26,2010 with Ron Berry(DWQ) and Rodney Willis and
John Casisa),
