Halifax County
Dear Mr. Gillham:
In accordance with your application for a discharge permit received on February 25, 2016, we
are forwarding herewith the subject certificate of coverage to discharge under the subject state — NPDES
general 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 US Environmental
Protection Agency dated October 15, 2007 (or as subsequently amended).
Please be aware that operations cannot begin until the associated mining permit is issued.
When the operations move from this initial mining area to the next one, you must submit for a
modification to the COC since the receiving waters will change.
Please take notice that this certificate of coverage (COC) is not transferable except after notice
to the Division of Energy, Mineral and Land Resources (DEMLR). The Division may require modificatior
or revocation and reissuance of the certificate of coverage.
Coverage under this General Permit for this facility is granted with the condition that the
permittee performs additional sampling requirements as outlined in the amended conditions to the
COC. These special provisions were prompted by effluent limitations required as per 40 CFR 440.50; and
monitoring required under the 2015 EPA Multi -Sector General Permit (MSGP). The additional provisions
for this COC are included on pages 2-5 of the COC.
These additional parameters include metals and other constituents which may be present or will
help us interpret the measurements (such as estimating the amounts of metals that are in dissolved
form). The Division will consider the data upon submittal to determine the most appropriate permitting
actions. It is possible that this facility will be directed to apply for an individual NPDES stormwater
discharge permit; and to the Division of Water Resources (DWR) for an individual NPDES wastewater
discharge permit prior to the expiration of this General Permit in 2020.

This permit does not affect the legal requirements to obtain other permits which may be
required by the Division of Energy, Mineral and Land Resources, or permits required by the Division of
Water Resources (DWR), Coastal Area Management Act, or any other federal or local governmental
permit that may be required. If the conditions as stipulated in the COC are unacceptable to you, you
may apply sooner for an individual NPDES discharge permit,
If you have any questions concerning this permit, please contact Robert Patterson at

Footnotes:
1. Sampling shall be performed during a measureable storm event, until either another permit is issued
for this facility or until this permit is revoked or rescinded. If the facility is monitoring monthly because
of Tier Two or Three response actions under the previous General 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 or the Division.
2. Measurement Frequency: Twice per year (unless other provisions of this permit require monthly
sampling).
3. Measurement Frequency: Once in the first year for these parameters, and then continue twice per year
(unless other provisions of this permit require monthly sampling) for all subsequent years for any
parameters for which the benchmark was exceeded in the first year.
4. Grab samples shall be collected within the first 30 minutes of discharge. Where physical separation
between outfalls prevents collecting all samples within the first 30 minutes, the permittee shall begin
sampling within the first 30 minutes, and shall continue until completed.
5. Sample Location: Samples shall he collected at each stormwater discharge outfall (SDO) unless
representative outfall status (ROS) has been granted. A copy of the Division's letter granting ROS shall be
kept on site with the SPPP.
6. Turbidity must be monitored at the stormwater discharge outfall (SDO). In addition to the SDO, the
permittee may elQct to also monitor turbidity in the receiving water, directly upstream (U) and
downstream (D) of the stormwater discharge outfall or group of outfalls to demonstrate the discharge
has not caused a water quality standard violation of turbidity. if SDO turbidity level exceeds the
benchmark, and the permittee cannot demonstrate the discharge has not caused a violation of the
Page 2 of 5 1 COC No. NCG020895 effective May 31, 2017

instream water quality standard, the Division may require the permittee to monitor turbidity up -
and downstream as part of a Tier 2 or 3 response.
7. Benchmark values apply for these parameters and prompt Tier responses as outlined in the General
Permit. Benchmark values for metals are based on one half the Final Acute Value (1/2 FAV), a threshold
used to protect against acute impacts to aquatic life.
8. For each sampled measureable storm event the total precipitation must be recorded. An on -site rain
gauge or local rain gauge reading must be recorded.

Footnotes:
1. The monitoring frequency is quarterly for the First year (see Table 9), and then semi-annually. If a
sample concentration exceeds any effluent limit in Table 8, monitoring frequency (all parameters)
shall return to (or remain) quarterly, until four (4) consecutive quarterly samples all meet or are below
the limit for all parameters, allowing the permittee to resume/reduce to semi-annual monitoring.
2. Sample Location: E - Effluent, U - Upstream, D - Downstream. Turbidity must be monitored at the
effluent (E). If effluent levels exceed the Water Quality Standard of the receiving water, the permittee
must begin sampling turbidity directly upstream (U) and downstream (D) of the effluent outfall or group
of outfalls, in addition to the effluent, upon the next monitoring period. The permittee may contact the
DEMLR Regional Office for assistance in determining the best instream sample points. The RO may also
advise the permittee to relocate self -established instream sample points if appropriate.
Page 3 of 5 1 COC No. NCG020895 effective May 31, 2017

3. Only facilities discharging to waters classified as HQW or ORW are required to monitor for settleable
solids.
4. Daily flow rate shall be recorded by a continuous flow measurement instrument. Alternatively, pump
curves and pump logs may be used as a means to calculate the daily flow rate.
S. No effluent limitation applies to these parameters.
6. Measurement Frequency: Once in the First year for these parameters, and then continue twice per year
(unless other provisions of this permit require monthly sampling) for all subsequent years for any
parameters for which the benchmark in Table 1 was exceeded in the first year.

Footnotes:
1. Note that for a semi-annual or quarterly sampling schedule, the sample result counts as both the Daily
Maximum and Monthly Average value. More frequent samples may be conducted to calculate averages
but must all be reported to NC DEQ.
2. Designated swamp waters can have a pH as low as 4.3 because of natural conditions. In such cases,
Federal Effluent Guidelines (40 CFR §436) allow the lower range of the pH limitations to be adjusted
downward to no lower than 5.0. The permittee must sample instream to demonstrate a lower limit is
appropriate.
3. No limit in the effluent discharge applies, but turbidity in the receiving waters shall not exceed levels
described below as a result of wastewater discharges.
4. The total daily flow rate of wastewater for all discharges combined (that discharge to the same receiving
waters) shall not exceed 50 percent of the total in -stream flow rate of the receiving waters under 7Q10
conditions in HQW/ORW waters, including HQW/ORW trout and PNA waters.
The discharge shall not cause the turbidity of the receiving water to exceed Water Quality
Standards:
25 NTU (all lakes and reservoirs, and all salt waters);
50 NTU (all other streams and surface waters).

V� 38) A wastewater treatment alternatives review is required by 15A NCAC 2H.0105 (c)(2)
for any new or expanding water pollution control facility discharges in North Carolina. You may
attach additional sheets. List the types of wastewater this mine site will discharge:
❑ Mine Dewatering
0 Process Wastewater (such as washing or recycle system overflows, other mining activity wastewater)
n n
a) What wastewaters were considered for this alternatives review? 0 Dewatering 0 Process WW
b) Connection to a Municipal or Regional Sewer Collection System:
n
i) Are there existing sewer lines within a one -mile radius? ..................................... ❑ Yes ❑. No
(1) If Yes, will the wastewater treatment plant (WWTP) accept the wastewater? .... ❑ Yes ❑ No
(a) If No, please attach a letter documenting that the WWTP will not accept the wastewater.
(b) If Yes, is it feasible to connect to the WWTP? Why or why not?*
c) Closed -loop Recycle System (meets design requirements of 15A NCAC 2T .1000):
n
i) Are you already proposing a closed -loop recycle system (CLRS)? ......................... 0 Yes ❑ No
f 1
(1) If Yes, for what type of wastewater at this mine site? ElDewatering 0 Process WW
(2) If No, is this option technologically feasible (possible)? Why or why not?
(3) If No, is it otherwise feasible to build a CLRS at this site? Why or why not?*
(4) What is the feasibility of building a CLRS compared to direct surface water discharge?* Both
CLRS and surface discharge are feasible. CLRS is the normal arrangement used by Iluka's other
operations where virtually all mine water is recirculated. Discharge of this water to a stormwater
outfail via their equalization basin and BMP is a viable alternative and could be required if they run
out of storage after a large event _
d) Surface or Subsurface Disposal System (e.g., spray irrigation):
n
i) Is a surface or subsurface disposal technologically feasible (possible)? ..................... 0 Yes ❑ No
Why or Why not?` The large quantities of water involved and the mobility of_the opera tio_n would
make this very expensive.
n
ii) Is a surface or subsurface disposal system otherwise feasible to implement?*............ ❑ Yes 0 No
Why or Why not?" A surface or subsurface disposal system would be very expensive to implement
because of the sometimes large quantities of water involved and the mobility of the operations.
iii) What is the feasibility of employing a subsurface or surface discharge as compared to a direct
discharge to surface waters?* A subsurface discharge would_ be difficult to implement because of the
large water volumes. A surface water discharge could be used to maintain fringing wetland areas.
e) Direct Discharge to Surface Waters: Is discharge to surface waters the most environmentally sound
alternative of all reasonably cost-effective options for the wastewaters being considered?*
