Subject: Final NPDES Permit Renewal
Permit NC0004308
Alcoa Badin Works
Stanly County
Class I Facility
Division personnel have reviewed and approved your application for renewal of the subject permit.
Accordingly, we are forwarding the attached NPDES permit. This permit is issued pursuant to the
requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement
between North Carolina and the U.S. Environmental Protection Agency dated October 15, 2007
(or as subsequently amended).
The name change request was addressed with the permit renewal. The name of the permittee was
changed to Badin Business Park, LLC.
In response to your comments dated November 18, 2015 the Division offers the following
responses:
• Critical dilution for outfall 012 - The Division agrees to use the chronic dilution of 26:1
(3.8 % IWC) for the whole effluent toxicity (WET) test for outfall 012. The WET test was
modified to reflect an IWC of 3.8 %.
• Cyanide limit for outfall 012 — The Division agrees to modify the acute daily limit using
the dilution factor of 14:1 and the non -trout criteria of 46.6 µg/1 that was used for other
outfalls. The cyanide daily maximum limit was modified to 652 µg/1.
• Compliance Schedule for outfalls 005, 011, 012, and 013 - Based on public concerns, the
Department withdrew the compliance schedule for outfalls 005, 011, 012, and 013. Alcoa
can employ other mechanisms for attaining compliance with new limits such as a special
order of compliance (SOC). This is a more appropriate mechanism than addressing the
non compliance with a schedule of compliance in the permit as the SOC is designed to
address compliance issues and track schedules and fines. Alcoa was aware that water
quality standards were exceeded at most outfalls for several years and has indicated that

studies had been started some time ago to identify the sources and develop an action plan.
These efforts can be included in the special order.
• Instream monitoring requirements - The Division modified the instream sampling
requirements considering the results of the CERCLA study. Special Condition A.(8)
includes requirements for a monitoring study to evaluate the effect of the new slurry wall
installed below the landfill. Sampling will be required in the three channels below the
landfill. Sampling stations in Little Mountain Creek were modified to three stations, one
station before the Alcoa Badin landfill, one after the landfill before the confluence with
the unnamed tributary, and one after the unnamed tributary downstream of NCSR 740.
• TCE limits Outfalls 011 and 012 — The Division does not agree to remove the limits for
TCE. The Division agrees to modify the limit using the state water quality standard of 2.5
µg/1 and to use the alternative name thrichloroethylene.
• Free cyanide vs Total Cyanide - North Carolina adopted a freshwater cyanide water
quality standard of 5 µg/1 for protection of aquatic life. The North Carolina water quality
standard to protect for aquatic life is expressed as total cyanide. EPA recently published
updated human health criteria for cyanide for consumption of water and for consumption
of organisms. Human health criteria applicable for water supply waters is 4 µg/1. Although
the reference doses EPA used for developing criteria were for free cyanide, the criteria is
expressed as total cyanide. Since the NC water quality standard is expressed as total
cyanide and the new EPA human health criteria is also expressed as total cyanide, the
limit in the permit is expressed as total cyanide.
• Frequency of toxicity testing at outfall 011 — The Division does not agree to change the
test from quarterly to annual. The quarterly chronic test for outfall 011 was implemented
to be consistent with outfalls 005 and 013 since they are all classified as discharges of
groundwater and stormwater.
• Monthly average limits and sample type outfall 011 — The Division agrees to change the
monitoring requirements for this outfall as it is not a continuous discharge. Sampling type
was modified to grab for all parameters. Limits were modified to acute limits as daily
maximums.
• Delete outfall 019 - The Division does not agree to delete outfall 019. There is limited
discharge data for this outfall. In addition, EPA suggested more monitoring for this
outfall. Although the monitoring suggested by EPA has not been implemented, once more
data is collected during this permit cycle the Division will reconsider removing the outfall.
• Outfall 019 monitoring/sample type - Sample type for flow was corrected to
instantaneous.
• Representative outfall status outfalls 018 and 022 — After consideration of the results of
the CERCLA Site Inspection Report completed by the Division of Waste Management the
monitoring requirements for outfalls 018 and 022 were modified. The permit was
modified to include monitoring requirements similar to other outfalls that discharge
stormwater and groundwater.
• Compliance schedule for stormwater outfalls - DEMLR does not agree to a schedule of
compliance. The tiered approach in the stormwater section is comparable to a built-in
compliance schedule for stormwater pollutants.

Page 13
As a result of comments received during the public comment period and additional revisions by
the Division the permit was modified as follows:
• Cyanide reporting level - The footnote for cyanide and fluoride was modified to require
the use of sufficiently sensitive test procedures.
• The RPA for outfall 005 was revised. As a result of the RPA a Total Residual Chlorine
daily maximum limit of 17 µg/1 for was added to this outfall.
• Daily maximum limits for continuous outfalls - Effluent limits for outfalls 011 and 012
were modified to include daily maximum limits for Trichloroethylene (TCE). Per federal
regulation 40 CFR § 122.45(d)(1) daily maximum and monthly average limits are required
for continuous discharges. The daily limits were calculated using a multiplier of 1.5 as
recommended by the EPA.
• Mixing zone analysis - Special Condition C. (7) was added to the permit to require an
updated mixing zone analysis for outfall 012. The mixing zone analysis that was
performed in 1990 was performed under different discharge conditions. Current conditions
and background concentrations should be evaluated using a current dilution model.
• The RPA for outfall 012 was revised to include total residual chlorine data. The data
presents no reasonable potential.
• The Division recommends that Alcoa requests the US Army Corps of Engineers (USAGE)
to issue a jurisdictional determination for the seepage/drainages from the Alcoa-Badin
landfill.
If any parts, measurement frequencies or sampling requirements contained in this permit are
unacceptable to you, you have the right to an adjudicatory hearing upon written request within
thirty (30) days following receipt of this letter. This request must be in the form of a written
petition, conforming to Chapter 150B of the North Carolina General Statutes, and filed with the
Office of Administrative Hearings (6714 Mail Service Center, Raleigh, North Carolina 27699-
6714). Unless such demand is made, this decision shall be final and binding.
Please note that this permit is not transferable except after notice to the Division. The Division
may require modification or revocation and reissuance of the permit. This permit does not affect
the legal requirements to obtain other permits which may be required by the Division of Water
Resources or any other Federal, State, or Local governmental permits that may be required.

SECTION B - STORMWATER MANAGEMENT REQUIREMENTS [G.S.143-215.1(a) et seq.,
15A NCAC 02H.0126 et seq.]
B.(1.) STORMWATER MONITORING REQUIREMENTS - Outfalls 002, 004, 017 & 020
During the period beginning on the effective date of this permit and lasting until the expiration date of this
permit, the Permittee is authorized to discharge stonnwater at Outfalls 002, 004, 017, and 020. Such
discharges shall be controlled, limited, and monitored as specified in this permit.
1. Analytical Monitoring_
Analytical monitoring of stormwater discharges shall be performed as specified below. All analytical
monitoring shall be performed during a measureable storm event.
A measurable storm event is a storm event that results in an actual discharge from the permitted site
outfall. The previous measurable storm event must have been at least 72 hours prior. The 72 -hour
storm interval does not apply if the permittee is able to document that a shorter interval is
representative for local storm events during the sampling period, and the permittee obtains approval
from the local DEMLR Regional Engineer (See Definitions).

until this permit is revoked or rescinded If the facility is monitoring monthly because of Tier Two
or Three response actions under the previous permit, the facility shall continue a monthly
monitoring and reporting schedule in Tier Two or Tier Three status until relieved by the provisions
of this permit by DEMLR
Page 12 of 32

Permit NC0004308
2. Grab samples shall be collected within the first 30 minutes of discharge When physical separation
between outfalls prevents collecting all samples within the first 30 minutes, sampling shall begin
within the first 30 minutes, and shall continue until completed
3. Sample Location: Samples shall be collected at each stormwater discharge outfall (SDO) unless
representative outfall status (ROS) has been granted. A copy of DEMLR's letter granting ROS shall
be kept on site.
4. For each sampled measureable storm event, the total precipitation must be recorded An on-site rain
gauge is required Where isolated sites are unmanned for extended periods of time, a local rain
gauge reading may be substituted for an on-site reading.
The permittee shall complete the analytical samplings in accordance with the schedule specified below,
unless adverse weather conditions prevent sample collection. A minimum of 60 days must separate
Period 1 and Period 2 sample dates, unless monthly monitoring has been instituted under a Tier Two
response. Inability to sample because of adverse weather conditions must be documented in the SPPP
and recorded on the DMR. The permittee must report the results from each sample taken within the
monitoring period (see Part 11, Section D) However, for purposes of benchmark comparison and Tiered
response actions, the permittee shall use the analytical results from the first sample with valid results
within the monitoring period.

Footnotes:
1. Maintain semi-annual monitoring until either another permit is issued for this facility or until this
permit is revoked or rescinded. The permittee must submit an application for renewal of coverage
before the submittal deadline (180 days before expiration) to be considered for renewed coverage
under the permit. The permittee must continue analytical monitoring throughout the permit
renewal process, even if a renewal permit is not issued until after expiration of this permit.
2. If no discharge occurs during the sampling period, the permittee must submit a monitoring report
indicating "No Flow' or "No Discharge' within 30 days of the end of the sampling period.
Failure to monitor semi-annually per permit terms may result in DEMLR requiring monthly monitoring
for all parameters for a specified time period. "No discharge" from an outfall during a monitoring period
does not constitute failure to monitor, as long as it is properly recorded and reported.
Page 13 of 32

Permit NC0004308
The permittee shall compare monitoring results to the benchmark values below. 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. See below the
descriptions of Tier One, Tier Two, and Tier Three response actions. In the event that DEMLR releases the
permittee from continued monthly monitoring and reporting under Tier Two or Tier Three, DEMLR's release
letter may remain in effect through subsequent reissuance of this permit, unless the release letter provides for
other conditions or duration.

The benchmark values above are no-- permit limits but should be used as guidelines for implementation of
the permittee's SPPP. An exceedance of a stormwater benchmark value is not a permit violation; however,
failure to respond to the exceedance as outlined in this permit is a violation of permit conditions.
Tier One
If: The first valid sampling results are above a benchmark value for any parameter at any outfall;
Then: The permittee shall:
1. Conduct a stormwater management inspection of the facility within two weeks of receiving
sampling results.
2. Identify and evaluate possible causes of the benchmark value exceedance.
3. Identify potential, and select the specific feasible: source controls, operational controls, or physical
improvements to reduce concentrations of the parameters of concern.
4. Implement the selected feasible actions within two months of the inspection.
5. Record each instance of a Tier One response in the SPPP. Include the date and value of the
benchmark exceedence, the inspection date, the personnel conducting the inspection, the selected
actions, and the date the selected actions were implemented.
6. Note: Benchmark exceedances for a different parameter separately trigger a tiered response.
Page 14 of 32

Permit NC0004308
Tier Two
If: The first valid sampling results from two consecutive monitoring periods are above the benchmark
values for any specific parameter at a specific discharge outfall;
Then: The permittee shall:
1. Repeat all the required actions outlined above in Tier One.
2. Immediately institute monthly monitoring and reporting for all parameters. The permittee shall
conduct monthly monitoring at every outfall where a sampling result exceeded the benchmark value
for two consecutive samples. Monthly (analytical and qualitative) monitoring shall continue until
three consecutive sample results are below the benchmark values or within benchmark range.
3. If no discharge occurs during the sampling period, the permittee is required to submit a monthly
monitoring report indicating "No Flow' to comply with reporting requirements.
4. Alternatively, in lieu of steps 2 and 3, the permittee may, after two consecutive exceedances, exercise
the option of contacting the DEMLR Regional Engineer as provided below in Tier Three. The
Regional Engineer may direct the response actions on the part of the permittee as provided in Tier
Three, including reduced or additional sampling parameters or frequency.
5. Maintain a record of the Tier Two response in the SPPP.
6. Continue Tier Two response obligations throughout the permit renewal process.
Tier Three
If. The valid sampling results required for the permit monitoring periods exceed the benchmark value for
any specific parameter at any specific outfall on four occasions, the permittee shall notify the DEMLR
Regional Engineer in writing within 30 days of receipt of the fourth analytical results;
Then: The Division may but is not limited to:
• require that the permittee revise, increase, or decrease the monitoring and reporting frequency for
some or all of the parameters herein;
• require sampling of additional or substitute parameters;
• require the permittee to install structural stormwater controls;
• require the permittee to implement other stormwater control measures;
• require the permittee to perform upstream and downstream monitoring to characterize impacts on
receiving waters; or
• require the permittee implement site modifications to qualify for a No Exposure Exclusion;
• require the permittee to continue Tier Three obligations through the permit renewal process.
2. Qualitative Monitoring Requirements
The purpose of qualitative monitoring is to evaluate the effectiveness of the Stormwater Pollution
Prevention Plan (SPPP) and identify new potential sources of stormwater pollution. Qualitative
monitoring of stormwater outfalls must be performed during a measurable storm event.
Qualitative monitoring requires a visual inspection of each stormwater outfall regardless of
representative outfall status. Qualitative monitoring shall be performed semi-annually as specified
below, and during required analytical monitoring events (unless the permittee is required to perform
further qualitative monitoring per the Qualitative Monitoring Response, below). Inability to monitor
because of adverse weather conditions must be documented in the SPPP and recorded on the
Qualitative Monitoring Report form (see Adverse Weather in Definitions). Only SDOs discharging
stormwater associated with industrial activity must be monitored (See Definitions).
Page 15 of 32

Permit NC0004308
In the event an atypical condition is noted at a stormwater discharge outfall, the permittee shall
document the suspected cause of the condition and any actions taken in response to the discovery. This
documentation will be maintained with the SPPP.

2. Monitoring Location: Qualitative monitoring shall be performed at each stormwater discharge
outfall (SDO) regardless of representative outfall status.
A minimum of 60 days must separate monitoring dates, unless additional sampling has been instituted as
part of other analytical monitoring requirements in this permit
If the permittee's qualitative monitoring indicates that existing stormwater BMPs are ineffective, or
that significant stormwater contamination is present, the permittee shall investigate potential causes,
evaluate the feasibility of corrective action, and implement those corrective actions within 60 days, per
the Qualitative Monitoring Response, below. A written record of the permittee's investigation,
evaluation, and response actions shall be kept in the SPPP
Page 16 of 32

Permit NC0004308
Qualitative Monitoring Response
Qualitative monitoring is for the purposes of evaluating SPPP effectiveness, identifying new
potential sources of stormwater pollution, and prompting the permittee's response to pollution. If
the permittee repeatedly fails to respond effectively to correct problems identified by qualitative
monitoring, or if the discharge causes or contributes to a water quality standard violation, DEMLR
may but is not limited to:
• require that the permittee revise, increase, or decrease the monitoring frequency for some or'
all parameters (analytical or qualitative)
• require the permittee to install structural stormwater controls;
• require the permittee to implement other stormwater control measures;
• require the permittee to perform upstream and downstream monitoring to characterize
impacts on receiving waters; or
• require the permittee implement site modifications to qualify for a No Exposure Exclusion.

discharges The permittee shall re -certify annually that the stormwater outfalls have been
evaluated for the presence of non-stormwater discharges If non-stormwater discharges are
present, the permittee shall identify the source and record whether the discharge is otherwise
permitted (by rule or a different permit) The permittee shall evaluate the environmental
significance of the non-stormwater discharges and include a summary written record with the
certification The certification statement and summary written record shall be retained with the
SPPP, and shall be dated and signed in accordance with the requirements found in Standard
Conditions for NPDES Permits, Part II, Section B.11(b).
(f) If a permanent source of non-stormwater flow is identified in accordance with B. (2)1. (e) the
permittee shall notify DWR and DEMLR. The notification must include a description and frequency
of discharge for the identified non-stormwater flow The notification must be submitted to the

description of the materials management practices employed which control or minimize the stormwater
exposure of significant materials, including structural and nonstructural measures The Stormwater
Management Strategy, 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
rainfall and run-on flows. 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, this review shall document the feasibility of diverting the
stormwater run-on away from areas of potential contamination.
(b) Secondary Containment Requirements and Records. Secondary contamment 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). 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 (5)
years. For facilities subject to a federal oil Spill Prevention, Control, and Countermeasure Plan
(SPCC), any portion of the SPCC Plan fully compliant with the requirements of this permit may be
used to demonstrate compliance with this permit.
(c) BMP Summary. A listing of site structural and non-structural Best Management Practices (BMPs)
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 on 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 Procedures. The Spill Prevention and Response Procedures (SPRP)

facility. Facility personnel 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 increased 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 (SPCC) may be a component of the SPRP, but may
Page 19 of 32

Permit NC0004308
not be sufficient to completely address the stormwater aspects of the SPRP. The common elements of
the SPCC with the SPRP 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 and implemented. The program shall address all stormwater
control systems (if applicable), stormwater discharge outfalls, all on-site and adjacent surface waters and
wetlands, industrial activity areas (i icluding 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 where not
already addressed under another element of the SPPP. 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 and
maintained in the SPPP.
Facility Inspections. Inspections cf 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 frequently than
semi-annually). These facility inspections are different from, and in addition to, the stormwater
discharge characteristic monitoring at the outfalls required in Part I Section B.(1.).
6 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 The facility personnel responsible for implementing the training shall be identified,
and their annual training shall be documented by the signature of each employee trained.
7. Responsible Party. The SPPP shall identify a specific position or positions responsible for the overall
coordination, development, implementation, and revision of the SPPP Responsibilities for all
components of the SPPP shall be documented and position assignments provided.
8. SPPP Amendment and Annual Update. The permittee shall amend the SPPP whenever there is a
change in design, construction, operation, site drainage, maintenance, or configuration of the physical
features which may have a significant effect on the potential for the discharge of pollutants to surface
waters. All aspects of the SPPP shall be reviewed and updated on an annual basis The annual update
shall include:
(a) an updated list of significant spills or leaks of pollutants for the previous three (3) years, or the
notation that no spills have occurred (element of the Site Overview);
(b) a written re-cerhficat±on that the stormwater outfalls have been evaluated for the presence of non-
stormwater discharges (element of the Site Overview);
(c) a documented re-evaluation of the effectiveness of the on-site stormwater BMPs (BMP
Summary element of the Stormwater Management Strategy)
(d) a review and comparison of sample analytical data to benchmark values (if applicable) over the
past year, including a discussion about Tiered Response status. The permittee shall use the
Annual Summary Data Monitoring Report (DMR) form, available from the DEMLR
Stormwater Permitdng Program's website (See 'Monitoring Forms' here:
http //portal ncdenr.org/web/Ir/npdes-stormwater).
The Director may notify the permittee when the SPPP 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
Page 20 of 32

Permit NC0004308
the Director for modifying the SPPP 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.
9. SPPP Implementation. The permittee shall implement the Stormwater Pollution Prevention Plan and
all appropriate BMPs consistent with the provisions of this permit, in order to control contaminants
entering surface waters via stormwater. Implementation of the SPPP 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 (5) years and made available to the Director or the Director's authorized
representative immediately upon request.
B.(3.) STORMWATER DEFINITIONS
Adverse Weather
Adverse conditions are those that are dangerous or create inaccessibility for personnel, such as local
flooding, high winds, or electrical storms, or situations that otherwise make sampling impractical.
When adverse weather conditions prevent the collection of samples during the sample period, the
permittee must take a substitute sample or perform a visual assessment during the next qualifying
storm event. Documentation of an adverse event (with date, time and written narrative) and the
rationale must be included with your SPPP records Adverse weather does not exempt the
permittee from having to file a monitoring report in accordance with the sampling schedule
Adverse events and failures to monitor must also be explained and reported on the relevant DMR
2 Allowable Non-Stormwater Discharges
Non-stormwater discharges which shall be allowed in the stormwater conveyance system include.
a. Uncontaminated groundwater, foundation drains, air -conditioner condensate without added
chemicals, springs, discharges of uncontaminated potable water, waterline and fire hydrant
flushings, water from footing drains, flows from riparian habitats and wetlands.
b. Discharges resulting from fire -fighting or fire -fighting training, or emergency shower or eye
wash as a result of use in the event of an emergency.
3. Best Management Practices (BMPs)
Measures or practices used to reduce the amount of pollution entering surface waters. BMPs may
take the form of a process, activity, or physical structure. More information on BMPs can be found
at: http://cfpub.ega.gov/npdes/stormwater/menuofbmps/index.cftn.
4. Bypass (stormwater)
A bypass is the known diversion of stormwater from any portion of a stormwater control facility
including the collection system, which is not a designed or established operating mode for the
facility.

7. Landfill
A disposal facility or part of a disposal facility where waste is placed in or on land and which is not
a land treatment facility, a surface impoundment, an injection well, a hazardous waste long-term
storage facility or a surface storage facility.
8. Measureable Storm Event
A storm event that results in an actual discharge from the permitted site outfall. The previous
measurable storm event must have been at least 72 hours prior. The 72 -hour storm interval may not
apply if the permittee is able to document that a shorter interval is representative for local storm
events during the sampling period, and obtains approval from the local DEMLR Regional Office.

seq.]
The permittee shall conduct acute toxicity tests on a quarterly basis using protocols defined in the North
Carolina Procedure Document entitled "Pass/Fail Methodology For Determining Acute Toxicity In A Single
Effluent Concentration" (Revised December 2010 or subsequent versions). The monitoring shall be
performed as a Fathead Minnow (Pimepliales promelas) 24 hour static test. The effluent concentration at
which there may be at no time significant acute mortality is 90% (defined as treatment two in the procedure
document) The tests will be performed once during each calendar quarter (January -March, April -June,
July -September and October -December). Effluent sampling for this testing must be obtained during
representative effluent discharge and shall be performed at the NPDES permitted final effluent discharge
below all treatment processes.
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 :he months specified above.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge
Monitoring Form (MR -1) for the month in which it was performed, using the parameter code TGE6C.

3. How to Request a Waiver from Electronic Reporting
The permittee may seek a temporary electronic reporting waiver from the Division. To obtain an
electronic reporting waiver, a permittee must first submit an electronic reporting waiver request to the
Division. Requests for temporary electronic reporting waivers must be submitted in writing to the
Division for written approval at least sixty (60) days prior to the date the facility would be required
under this permit to begin submitting monitoring data and reports The duration of a temporary waiver
shall not exceed 5 years and shall thereupon expire. At such time, monitoring data and reports shall be
submitted electronically to the Division unless the permittee re -applies for and is granted a new
temporary electronic reporting waiver by the Division. Approved electronic reporting waivers are not
transferrable Only permittees with an approved reporting waiver request may submit monitoring data
and reports on paper to the Division for the period that the approved reporting waiver request is
effective.
Information on eDMR and the application for a temporary electronic reporting waiver are found on the
