a cover sheet, stamped or typed legend, or other suitable form of notice employing language such as "trade
secret," "proprietary," or "company confidential." Allegedly confidential portions of otherwise

certain date or until the occurrence of a certain event, the notice should so state."
If you assert such a claim for the requested information, the EPA will only disclose the information to the
extent and under the procedures set out in the cited regulations. If no business confidentiality claim
accompanies the information, the EPA may make the information available to the public without any
further notice to you.

Dear Mr. Bradley:
Donald R. van der Vaart

November 16, 2015
Subject: General Permit No. NCG020000
Unimin Corporation Quartz Operation
COC NCGO20793
Mitchell County
In accordance with your request for a discharge permit received on May 30, 2014, 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 take notice that this certificate of coverage is not transferable except after notice to the
Division of Energy, Mineral, and Land Resources. The Division may require modification or revocation and
reissuance of the certificate of coverage (COC).
Coverage under this General Permit for this particular 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 results of sampling at this facility during the week of June 8,
2015, as requested by EPA Region 4 staff who performed a Compliance Sampling Inspection (CSI) at the end
of March 2015. Sample concentrations raised concerns about metals levels in the discharges. The DEQ
concluded that more data was needed to evaluate these discharges and potential water quality impacts. The
additional provisions for this COC include:
1) In addition to the parameters in NCG020000, sample each stormwater discharge outfall (SDO)
quarterly for five metals, fluoride, chloride, and total hardness listed in Table 1 as amended on page 2
of the COC. Benchmark values apply for many of these added parameters, and the permittee must
follow tiered responses as outlined in the permit.
2) In addition to the parameters in NCG020000, sample each wastewater discharge quarterly for five
metals, fluoride, chloride, and total hardness listed in Table 7 as amended on page 3 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 to the Division of Water Resources (DWR) for an
individual NPDES discharge permit (or modification of its existing wastewater individual permit) priortothe
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 Bradley Bennett at telephone number
[phone], or Bethany Georgoulias at telephone number [phone].

Footnotes:
1. Measurement Frequency: Quarterly (unless other provisions of this permit require monthly sampling)
during a measureable stoim 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. 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.
3. Sample Location: Samples shall be 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.
4. Turbidity must be monitored at the stormwater discharge outfall (SDO). In addition to the SDO, the
permittee may elect 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
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.
S. 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 (2h FAV), a threshold
used to protect against acute impacts to aquatic life.
6. 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.
2. Except for mine dewatering of clay pits, a grab sample is not required for these parameters from a
basin/pond designed to contain or treat mine dewatering wastewater that only discharges in
response to rainfall in excess of the 10-yr, 24-hr storm.
3. 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.
4. All facilities that are mining Industrial Sand are required to monitor TSS and are subject to the TSS
limits in Table 8. All other types of mines covered by this permit are also required to monitor TSS, but
are not necessarily subject to the TSS limits in Table 8, unless discharge is to HQW, ORW, or PNA waters.
5. Only facilities discharging to waters classified as HQW, ORW, SA, SB, Tr, or PNA are required to monitor
for settleable solids.
6. No effluent limitation applies to these parameters.
7. 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.

Good afternoon, Kip,
The special COCs forthese three mine sites were signed today. Copies of those COCs and cover letters are attached. I
have already emailed the permit contacts copies of these, and hard copy packages will go out to them this week with
revised monitoring forms to include the additional metals, etc.
We will be working with our counterparts in the Division of Water Resources' NPDES Wastewater Permitting program on
future permitting actions for these sites over the next 1-2 years. Please let us know if you have any questions.

Subject: NPDES Permit Renewal NCG020793 for Mining Operation at Unimin Quartz Site
Importance: High
Mr. Ferguson,
As you may know, the U.S. EPA Region 4 personnel from Atlanta, GA conducted a Compliance Evaluation Inspection at
this site the week of March 30, 2015. Subsequent sampling was conducted in June as a follow-up to that inspection. NC
DEQ has discussed with EPA the concerns raised by those sample results, and we have determined that permit renewal
for this facility should be handled differently than in past years.
Unimin Corporation requested renewal coverage under the NPDES General Permit NCG020000 for this facility in Spruce
Pine, NC, and indicated electronic COC renewal as the preferred option. However, NC DEQ will issue this facility a
special Certificate of Coverage under NCG02 that will require additional discharge parameters be measured. We will be
sending you a paper renewal package with a cover letter explaining the basis for revised monitoring requirements in lieu
of an email with instructions for on-line COC renewal. The conditional COC will allow continued coverage under the
General Permit for the time being.
Please be on the lookout for this important correspondence in the coming weeks.

this site the week of March 30, 2015. Subsequent sampling was conducted in June as a follow-up to that inspection. NC
DEQ has discussed with EPA the concerns raised by those sample results, and we have determined that permit renewal
for this facility should be handled differently than in past years.
Unimin Corporation requested renewal coverage under the NPDES General Permit NCG020000 for this facility in Spruce
Pine, NC, and indicated electronic COC renewal as the preferred option. However, NC DEQ will issue this facility a
special Certificate of Coverage under NCG02 that will require additional discharge parameters be measured. We will be
sending you a paper renewal package with a cover letter explaining the basis for revised monitoring requirements in lieu
of an email with instructions for on-line COC renewal. The conditional COC will allow continued coverage under the
General Permit for the time being.
Please be on the lookout for this important correspondence in the coming weeks.

Stan,
After a protracted discussion with EPA prior to the renewal of the NCG020000 General Permit for Mining Activities, we
have issued special Certificates of Coverage that are "augmented" with additional monitoring for stormwater and
wastewater discharged by these three mine/processing operations. Please see the attached cover letters and
COCs. We will coordinate with DWR on future permitting steps in the next 1-2 years. It is likely these sites will transition
into individual NPDES wastewater permits under DWR after more data are collected and sooner than the GP expiration
in five years. For now, they continue to be covered under the NCG02 permit with more monitoring and a base quarterly
frequency.
The additional parameters include ones that Tom Belnick recommended based on other similar mines permitted
through their program and metals that raised concern for EPA during their sampling visits in June. Linda Wiggs with
DWR has also been instrumental in helping us through this process. She was present for some of the sampling during
EPA's visit, and she has a valuable perspective from both a wastewater sampling background and previous Stormwater
Permitting Program experience. Although we have concerns about EPA's sampling approach and some results, the
added monitoring under the General Permit will allow DEQ to obtain more data and evaluate a different permitting
strategy for these facilities.
Everyone - these attachments serve as the CC's indicated in the letter to the other DEQ Central Office and ARO
staff. Please include them in the permit files there. (I have additional hard copies for two of the NPDES wastewater
permit files here in Central Office that I'll get to Tom Belnick.)
If you all have any questions, please let us know.
Thanks,

Forgot to mention. In the EPA letter dated 9/30/2015 for their recommendations for NPDES Permit NCG020000, they
incorrectly stated in Recommendation 2, bullet 2, a minimum of monthly monitoring for toxics and toxicity (citing our
213.0500 monitoring requirements). In truth, toxics/toxicity are separated out from other parameters subject to Monthly
Monitoring.

Subject: RE: NPDES Permit Renewal NCG020274 for Mining Operation at Pine Mountain M&P
Bethany- I took a look at our 6 existing Individual Unimin/Feldspar NPDES permits and offer the following comments
with regard to your draft Table 7 Monitoring Requirements for Wastewater Discharges:
1. All our permits have fluoride limits, since fluoride is used in the extraction process.
2. All our permits have chloride monitoring, which is also used in the process.
3. 1 would add monitoring for aluminum, since alum is used sometimes.
4. 1 would add monitoring for nickel and zinc, which was checked as "Believed Present" in some applications, and
there are current water quality standards/criteria to run an RPA.

5. I'm not sure of value of monitoring for antimony, arsenic, chromium, copper, iron, lead, magnesium,
manganese, strontium, titanium, vanadium, since I'm not clear on what the source of these toxicants would be,
some lack water quality standards/criteria to run RPA, etc.
6. If these permits came to NPDES wastewater, we would include a quarterly toxicity test limit which would cover
the potential impact of all toxicants present (even if we didn't monitor for all of the above).
7. 1 don't see the basis for the fecal coliform limit to SA water- what would be the source of fecal from a mining
operation?
8. All our permits have pH limits without exemption.
Effluent Guideline based.
In this case it would be water quality -based rather than
Overall, the historical issues in North Toe River have been fluoride (used in the process) and instream impairment due to
turbidity. Hope this helps, let me know if any questions.

Hi Tom,

Have you all made any headway on what preferred parameter list we should include in our "special" COCs for Unimin
and Quartz Corp sites in Mitchell County? We will need to issue them coverage as soon as we can since the general
permit became effective at the beginning of October.
Thanks!

COMPLIANCE SAMPLING INVESTIGATION REPORT
UNIMIN CORPORATION NCG020793
SPRUCE PINE, NORTH CAROLINA
I. INTRODUCTION
On June 11, 2015, representatives of the U.S. Environmental Protection Agency, Science and
Ecosystem Support Division (USEPA- SESD), conducted a Compliance Sampling Inspection
(CSI) at the Unimin Corporation Quartz Mine NCG020793 in Spruce', Pine, North Carolina. The
CSI was performed at the request of the Water Protection Division, EPA Region 4.
The CSI was conducted to support an NPDES Compliance Evaluation Inspection, which was
conducted the week of March 34th, 2015 by the EPA Water Protection Division (WPD)
personnel from Atlanta, Georgia. The primary focus of this investigation was to sample all
permitted outfalls that were discharging.

SESD sampled seven locations across the mine. In -situ measurements included temperature, pH,
turbidity, and dissolved oxygen which are included in Table 1. Samples were analyzed for Total
Recoverable Metals, Total Suspended Solids (TSS), Total Dissolved Solids (TDS), and hardness
(as CaCO3).
III. DISSCUSSION OF FIELD ACTIVITIES
The objective of the SESD investigation was to collect samples corresponding with NPDES
permit NCG020793. Due to time constraints the samples were not taken within 30 minutes of a
rain event as required by the permit. Rainfall data from the site is included in Table 2. Based on
authoritative sampling design, SESD sampled seven locations across the mining site. These
locations had sufficient flow to collect representative samples. Figure 1 displays the locations.
GPS coordinates are included with the photos in Appendix A. All photos were taken by Cornell
Gayle.
All samples were grab samples. Samples were collected at the end of the respective discharge
pipes directly into 1 L wide mouth polyethylene bottles. The discharge pipes drain runoff from

Subject: Review of Draft National Pollutant Discharge Elimination System General Permit for Non -
Metallic Mineral Mines, NCO020000
Dear Mr. Vinson:
On June 5, 2015, the above referenced National Pollutant Discharge Elimination System (NPDES) draft
general permit (GP) and supporting documents were received by the U.S. Environmental Protection
Agency Region 4 from the North Carolina Department of Environment and Natural Resources
(NCDENR). We have completed our review of the draft GP and supporting documents and are
providing comments in accordance with Section IV.B.3 of the North Carolina/EPA Memorandum of
Agreement (MOA) and 40 Code of Federal Regulations (CFR) § 123.44(a).
The EPA and NCDENR have worked together to resolve many issues in the draft GP. The NCDENR
has committed to: revise the notice of intent to be more consistent with NC's antidegration policy, add
questions to the notice of intent that will more clearly identify the outfalls and receiving streams, include
conditions in the GP to protect sensitive streams, and clarify definitions for wastewater and stormwater.
These are significant improvements and we commend NCDENR's efforts to provide further additions
and water quality protections to the GP. It is in this context that we recommend additional measures (see
enclosure) for your consideration.
The EPA remains concerned that discharges from facilities covered by this GP may cause environmental
impacts. The EPA's recommendations relate to this draft GP, which covers 424 mining facilities, are
described in detail in the enclosed attachment. We recommend the GP contain effluent limits and
monitoring frequencies as stringent as necessary to ensure that the proposed discharges will not cause or
contribute to a violation of numeric or narrative water quality standards (WQS), as required by the Clean
Water Act § 301(b)(1)(C), 40 CFR § 122.4((a) and (d)), and 40 CFR § 122.44(d)(1). Additionally, our
recommendations take into consideration the effluent and in stream data collected by the EPA from
three facilities currently covered under this GP.
We request that the NCDENR consider these recommendations and revise the draft GP and fact sheets
to address them before issuing the final GP. In accordance with our MOA, we also request that you
provide a response to our comments and to any public continents you receive. If substantial changes to
the GP are made beyond our recommendations, we ask that you provide the proposed GP to us prior to
final issuance for our review. Please let me know if you have any questions or concerns. If you have any

Recommendations for NPDES permit NCG020000
The EPA collected effluent and in -stream data from three facilities (NCG020274, NCG020818, and
NCG020793) covered under this GP in June of 2015. The water quality data revealed concentrations
of copper, lead, and zinc that may cause or contribute to exceedances of NC current WQS. The data
also shows that certain metals concentrations may cause or contribute to violations of NC's proposed
WQS (that are more stringent than the current WQS for certain pollutants) or EPA's recommended
criteria. The EPA believes that a reasonable potential analysis should be conducted using this data
and other relevant information to properly assess the risk of exceeding NC WQS for metals at these
facility's outfalls. If reasonable potential exists for these facility's discharges to cause or contribute
to an exceedance of any WQS, the EPA would expect these facilities be covered under individual
NPDES permits.
The presence of metals in this effluent data may be indicative of a problem industry -wide or a
problem within an industry subcategory. In order to fully understand the potential concentrations of
metals present in this industry's discharges, the EPA and NCDENR recognize the need for
additional testing of effluent and receiving streams for metals from facilities covered under this GP.
The EPA and NCDENR will work together to determine how to obtain more industry -specific water
quality data for metals. A reasonable potential analysis is required after the collection of more water
quality data from the industry in accordance with 40 CFR § 122.44(d)(1). If reasonable potential is
found for the discharges to cause or contribute to WQS exceedances in the results of the additional
data collected, the EPA encourages the NCDENR to include water quality -based effluent limits
applicable to the industry or industry subcategory as required by 40 CFR § 122.28(a)(3).
2. The monitoring frequency for all wastewater parameters is twice per year. The monitoring frequency
for all stormwater parameters is semi-annually until a tier two action is required. The EPA is
concerned that this draft GP may not include monitoring frequencies necessary to capture an
accurate scope of pollutant concentrations in the effluent pursuant to 40 CFR § 122.48. Additionally,
the EPA is concerned that the information in the fact sheet does not support a semi-annual
monitoring frequency. For the reasons described below the EPA recommends that the final GP
contain monthly monitoring frequencies for all stormwater and wastewater parameters.
• The quarterly monitoring effluent data reported for some facilities are exceeding multiple
pollutant benchmarks and limitations. Facilities with problems achieving compliance should
generally be required to perform more frequent monitoring, not less frequent monitoring, to
assess noncompliance.
• The minimum monitoring frequency for mining discharges is provided in North Carolina's
WQS. These regulations specify a minimum monitoring frequency of monthly for turbidity,
seattleable matter, total suspended solids (TSS), pH, toxics, and toxicity for mining facilities that
are within standard industrial classification 1400-1499 (15A NCAC 02B.050B). The GP covers
mining facilities that are in standard industrial classification 1400-1499.
• Semi-annual monitoring frequencies would make it difficult to apply and enforce the maximum
daily and monthly average limits.
3. The North Carolina WQS for TSS limits wastewater discharges to 10 mg/L in trout waters (TR) and
20 mg/L for High Quality Waters (HQW). The draft GP has a benchmark value of 50 mg/L TSS for
stormwater outfalls that discharge to TR and HQW. While the WQS for TSS is applicable to

wastewater, it does not preclude the NCDENR from using best professional judgment to apply a
more protective benchmark for stormwater discharges. The EPA suggests that the GP include
stormwater benchmark levels of 10 mg/L and 20 mg/L to waters classified as TR to HQW,
respectively.
4. The North Carolina WQS for turbidity is connected to the background condition in the stream (15A
NCAC 02B .0221(21)). The draft GP requires turbidity monitoring at the stormwater discharge
outfall or directly upstream and downstream. The EPA is concerned that without the mandatory
collection of both effluent and in -stream turbidity concentrations, it cannot be known if a violation of
the benchmark criteria is occurring. The EPA suggests that final GP contain turbidity monitoring in
the effluent and in -stream samples for wastewater and stormwater discharges.
5. The currently effective GP requires settleable solids benchmarks for stormwater and limits for
wastewater. The seattleable solids limits for wastewater are being removed from the draft GP. North
Carolina's WQS support seattleable solids limits on certain sensitive waters (15A NCAC 02B .0221
and .0222). The EPA recommends that seattleable solids limits apply to wastewater discharges to
sensitive waters.

Hi Jeff,
,vow/ - >
>I had a couple of questions about the data you sent me - if you could answer
them...
>You seem to have monitored monthly for outfall 002- but that didn't seem to be a
requirement of the permit - only annually.
Outfall 002 is the same as HAW1
Now they have 5 different ponds.
HAW1 is mineeewatering and stormwater
All stowrmater going to HAW2 and 10-15 acres going to HAW2 go to hawl.
002 is just mine dewatering itself. Then it gets commingled with HAW1 in the
pond (HAW1). He is taking 002 from before it gets to
HAW3 - just being built
HAW5 - just being built
HAW2 - controls
HAW4 - it is officially a dam. It has not discharged to his knowledge.
The NPDES WW permit 001 (plant primary discharge - not on my maps) and 002
(basically HAW1 = Stor�wmater from HAW2 and 002 mine dewatering ww) are then the
only outfalls for _.
Everything reports to Hawl from Haw2.
Across the street, there are SC05, 05, 07, 08
PLT2, 3, 4, 5
PLT3 - they had a bunch of sand and 2-3 truckloads of sand and he had them
monitor it - but normally they are employee parking.

those -[I notified he will want to be careful of TSS with that].
PLT1 - totally interally draining
PLT4 - completely undisturbed.
PLT5 - completely undisturbed.

NCG02 Stormwater Permit: Mining Permit Review
Communication logs
Date Item
Is the Mine area and the plant area covered by the same (one) DLR permit? And
one NPDESWWpermit?
Why did Unimin call their mine Hawkins mine on the DLR form and Quartz
Operation on this mine?
Please revise NOI to read Unimin Corporation.
Page 4 of 4

We've received an NOI from Unimin Corporation — Quartz Operation for their facility in Spruce Pine
(Mitchell County) for coverage of their quartz/feldspar/alaskite mine under NCG02 (Mining SW/WW
permit). The site discharges stormwater and mine dewatering water into North Toe River, Little Bear
Creek and Bear Creek (I believe) — all C, Tr. The NOI is attached.
Their Mining Permit (61-04) from DLR was revised 3/3/11, and it looks like you guys already notified
them that this site needed an NPDES stormwater permit as well (a copy of the MRO letter was
attached). I had some questions for them — I think you are going to do a site visit? I called and left a
message but have not heard back from them yet.
If you go there, can you ask about or check on the following please?
1. Are these all the correct receiving streams? — check with ARO to see if all streams are correct
for SW permit.
a. All ultimately end up in the N. Toe River. But entire mine all run into Hawkins Branch.
2. DLR permit name is "Hawkins Mine" and Unimin Corporation. NPDES WW permit name is
"Unimin Corporation, Quartz Feldspar Operation". Which is correct? N01 says "Unimin
Corporation Quartz Operation" as legal owner name, however, "Unimin Corporation" is listed as
legal name in Secretary of State. Can you please ask them to resubmit an NOI that uses the
correct name? We need to use the name that is in the Secretary of State's database.
a. DLR permit is called Hawkins. Everything else called Unimin Quartz /Feldspar. Hawkins
mine was the previous owners, and when it was bought by Unimin.
b. He will send me a revised application first page with the correct owner on it.
3. Is all Process WW covered under NPDES WW permit?
a. Yes. All on one side of the road — down at the main plant. Our NPDES SW permit will
cover stormwater at the whole site — both sides of the road and mine dewatering mine
wastewater at the mine.
4. Is the Mine area and the plant area covered by the same (one) DLR permit? And one NPDES
WW permit?
a. Yes.
S. Also — as Unimin Corporation is the owner, what is their correct address? If you can ask them
to contact me and I will get that sorted out.
a. This will be fixed in his new application submittal.
6. Do you have data for Quartz mine?
a. He's been collecting data from the mine — can send to me.

confidentiality claims is found at 40 Code of Federal Regulations (CFR) Part 2.40 CFR § 2.203(b) states
that "A business which is submitting information to EPA may assert a business confidentiality claim
covering the information by placing on (or attaching to) the information, at the time it is submitted to EPA,
a cover sheet, stamped or typed legend, or other suitable form of notice employing language such as "trade
secret," "proprietary," or "company confidential." Allegedly confidential portions of otherwise
non -confidential documents should be clearly identified by the business, and may be submitted separately
to facilitate identification and handling by EPA. If the business desires confidential treatment only until a
certain date or until the occurrence of a certain event, the notice should so state."
If you assert such a claim for the requested information, the EPA will only disclose the information to the
extent and under the procedures set out in the cited regulations. If no business confidentiality claim
accompanies the information, the EPA may make the information available to the public without any
further notice to you.

Subject: data from Unimin Quartz Mine; Crystal Mine
Hi Jeff,
Thank you for taking the time to speak with me today. I've looked in the NPDES wastewater files here and unfortunately
there does not appear to be any stormwater data in their files for Unimin Quartz Mine. I believe that is another reason
why DWQ ARO requested separate wastewater and wastewater permits. If you can please scan and email or send me
copies of their data for the last 5 years for stormwater data from this site (if you have that data, or if not, please send
me what you can). Please also send me a copy of the first page of the application (NOI) with the correct owner name
and address and facility name. After I get those two items for Quartz Mine, I can proceed with issuing the permit if
everything is in order.
As for Unimin Crystal Mine, as we spoke about on the phone the Asheville Regional Office relayed to me (and you
confirmed on tTFe phone) that the Crystal Mine does have any individual stormwater outlets (as they all flow to a
pond which is commingled with wastewater). Because of that, I will withdraw your application for a stormwater permit
and you will only have an NPDES stormwater permit for that site. I will send you a letter stating that as well.
Thanks for your help with this matter and I look forward to hearing back from you.
Thank you again,
Jen

Per our telephone conversation today, please find enclosed revised NOI form page
2 of 9 and copies of analytical sampling performed on storm water outFAs as well as
monthly mine dewatering. I found copies of data back to November 2007. If you need to
go further in history, please let me know and we can dig deeper in the plant files or I can
make a trip to DWQ files to attempt to retrieve this data. As you will note, the operator
utilized the Process/Mine Dewatering DMR for mine dewatering through February 2009.
At that time, Mr. Bob Guerra with DWQ, requested that they utilize DMR Form MR-1 I
believe due to difficulties with input into the DWQ database.
