Dear Permittee:
John Skvarla, Ili
Secretary
S-ubject: Rescission of NPDES Stormwater Permit
Certificate of Coverage Number NCG020057
Plant #2
Mitchell County
The Division of Water Quality received your request to rescind your coverage under Certificate of
Coverage Number NCG020057. In accordance with your request, Certificate of Coverage Number
NCG020057 is rescinded effective immediately.
Operating a treatment facility, discharging wastewater or discharging specific types of stormwater to
waters of the State without valid coverage under an NPDES permit is against federal and state laws and
could result in fines. If something changes and your facility would again require stormwater or
wastewater discharge permit coverage, you should notify this office immediately. We will be happy to
assist you in assuring the proper permit coverage.
If the facility is in the process of being sold, you will be performing a public service if you would inform
the new or prospective owners of their potential need for NPDES permit coverage.
If you have questions about this matter, please contact Boyd DeVane at 919 807-6373, or the Water
Quality staff in our Asheville Regional Office at 828-296-4500.
Sincerely,
for Charles Wakild, P.E., Director

Unimin mothballing Crystal Plant

Wednesday, January 28, z009
Company also laying off employees at Red Hill plant, says employees will be back when conditions improve
Wesley Brown
News -Journal Staff
Unimin Corporation in response to a decrease in orders due to the worldwide economic recession is shutting
down their Crystal Plant in Spruce Pine and is laying off workers at their Red Hill plant.
"We are going to be mothballing the plant due to slow business conditions from the worldwide economic
recession," Unimin Execution Vice President Joe Shapiro said.
"We are closing it temporarily. We expect to reopen it when business conditions improve, and we do expect
business conditions to improve."
According to Shapiro, the plant, which has a total 47 employees (40 hourly and seven salaried) is laying off all of
the hourly employees.
Most of the lay-offs were effective Jan. 23. The remaining workers not laid off in January will be kept until
February so the company can perform an orderly shut down of the plant.
The seven salaried employees at the Crystal Plant are being reassigned to facilities in Mitchell and Avery counties
and will continue to work for the company.
At"th"eir plant in Red Hill, which has 73 employees (10 salaried and 63 hourly), the e company'is laying off"13—j
hourly-employees"effective ]an: 23-through:Jan.-25, depending on which job the employee performs.
(No.layoffs•are-beiR-g.made.at:the--Schoolhouse-Pla'ritan_Spruce:Pin@.7
Shapiro said that the lay offs are temporary and expects to hire the employees back.
"When the plant reopens, and it will reopen, we expect to be bringing people back," Shapiro said.
Before these moves, the company permanently laid-off_30_ofahe`46-hourly-em`ployees_at_the_Quarti/Feldspar
<plant in_Spruce'Pine-that°caught"fire-Nov: MThe remaining 16 employees were kept and reassigned to different
facilities.
Those that were permanently laid off met in groups with Chris Silvers, director of the Employment Security
Commission's Spruce Pine office, on Thursday Jan. 22 to discuss job options and enroll in Mayland Community
College's Workforce Investment Act program.
Silvers also said that there is not a whole lot going on in the local job market.
"Our advice is start seeking work in the fields that you have skills," Silvers said. "The best thing to do at this
point is to let a network of friends, family, or neighbors know you are seeking work."

Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
The facility has been conducting qualitative and analytical sampling events as required by the permit. The
site map clearly shows the drainage areas for each outfall. The location of the outfall corresponding to the
drainage area should be marked on the map. During the inspection it was difficult for inspectors to
ascertain the outfall location for each drainage area due to abundance of pipes and culverts at Mine Fork
Creek near the entrance. One of the pipes was discharging cloudy water though it was not raining during
the inspection. The source of this discharge should be determined and documented and if possible treated
to reduce turbidity. Additionally, the runoff from the process building down the road to the southern entrance
did not appear to be captured by the map or the narrative description of the outfalls. All outfalls must be
monitored unless a respresentative status has been applied for and received.
Mr. Snyder-man's assistance during the inspection was extremely helpful and appreciated. He indicated that
the facility has applied for representative outfall status over one year ago. We are following up with Raleigh
to determine the status of the application.
Inspectors noticed that there was extensive erosion on the road leading from the southern entrance to the
mine dewatering area. The erosion is currently directed into the creek. We suggest redirecting the flow into
the small sediment basin prior to discharge. Additionally, the sediment basin should be cleaned out.
Permit conditions require Best Management Practices (BMP) inspections to be conducted at least once
every seven calendar days and within 24 hours of any storm event that results in a discharge (NCG020000
Part III Section A.3).

No mining occurs at this site. Olivine is transported to this site from Unimin's Green'Mountain Plant #t in
Yancey County and is bagged and shipped from the Mitchell County site (Green Mountain Plant #2), No
crushing or wet processing occurs at this Mitchell County site. The only stormwater runoff leaving Green
Mountain Plant #2 is parking lot runoff.
Unimin should consider requesting 'rescission of the NCG020057 permit for Green Mountain Plant #2,
assuming that the Standard Industrial Classification (SIC.Code) for this particular site does not automatically
require stormwater permit coverage. Should the SIC Code automatically require a general stormwater
permit, the Green Mountain Plant #2 site does qualify for a no exposure exemption.

Unimin Green Mountain Plants 1&2 Prolonged Requests
Mr. Bennett, I have submitted numerous request over the past six (6) years for representative outfali
status of Unimin Corporation's Green Mtn. Plant 1. My latest letter to Aisha Lau (dated Oct. 1, 2007)
requested not only that she please act upon my previous. requests for representative outfall status (dated
12/1312002, 3/16/2004, 7126/2005) at Green Mtn. Plant'l but to also request that the general permit for
Green Mtn. Plant 2 (NCG020057) be.rescinded per recommendation of the Asheville Regional Inspectors
Laurie Moorhead and Starr Silvis (Water Compliance Inspection Report 512212006). 1 am becoming very
concerned that it has taken almost six years to act upon my initial request for representative status at PA.
1 and would greatly appreciate your Department acting upon this.request as well as rescinding Green
Mtn. Plant 2 general permit. I would greatly appreciate a response to my requests in the very near future.
Thank you in advance for your help with this matter -

Sec ian D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as cessary)
The facility has been conducting qualitative and analytical sampling events as requiregK the permit. The
site map clearly shows the drainage areas for each outfall. The location of the Duff corresponding to the
drainage area should be marked on the map. During the inspection it was diffic or inspectors to
ascertain the outfall location for each drainage area due to abundance of pipe and culverts at Mine Fork
Creek near the entrance. One of the pipes was discharging cloudy water t ugh it was not raining during
the inspection. The source of this discharge should be determined and cumented and if possible treated
to reduce turbidity. Additionally, the runoff from the process building wn the road to the southern entrance
did not appear to be captured by the map or the narrative /descrii6n of the outfalls. All outfalls must be
monitored unless a respresentative status has been.applid received.
Mr. Snyderman's assistance during the inspection was ahelpful and appreciated. He indicated that
the facility has applied for representative outfall status er one year ago. We are following up with Raleigh
to determine the status of the application. /
Inspectors noticed that there was extensive era 'dn on the road leading from the southern entrance to the.
mine dewatering area. The erosion is current) directed into the creek. We suggest redirecting the flow into
the small sediment basin prior to discharge./Additionally, the sediment basin should be cleaned out.
Permit conditions require Best Managerp6nt Prac#ices (BMP) inspections to be conducted at least once
every seven calendar days and within 4 hours of any storm event that results in a discharge (NCG020000
Part III Section A.3).

The inspector toured the facility with Jeff Ferguson. The inspection was initiated by a request to rescind the permit. After
the inspection, it was determined that the facility requires a permit; however, the inspector noted that the facility is hose to
meeting the requirements of No.Exposure,
Items noted during the inspection:
- Product is being lost to the ground surface and appears to be making it to a stormwater inlet near the railcar, loading
facility. Improvements should be made at this location to contain product.

Chuck,
I see your November 11, 2008, email to Sarah reporting that the permittee, Jeff
Ferguson I presume, has contacted you to ask about his request for rescission of
stormwater permit NCG020057 at Unimin's Green Mountain Plant #2.
I've reviewed the files today, and I note that GM#2 is -2+ miles remote from GM#1, a
sister facility supplying the mined ore to GM#2. Here's the significant history I see
in the files.
7/30/93 - NCG020057 issued in response to the permittee's application.
12/17/99 - COC reissued in response to the permittee's request.
2/7/05 - COC reissued in response to the permittee's request.
5/22/06 - ARO inspection letter to Unimin, noting that the site might not be required
to have an NPDES stormwater permit at all, or possibly the site might qualify for the
No Exposure.Exclusion from permitting based on observations on site. Inspection
report notes that no crushing or wet processing occurs at GM#2, and that the only
runoff is from the parking lot. [Significantly, perhaps, the CEI records that while
olivine is the material being mined at GM#1, it is being bagged and shipped from GM#2,
the facility under consideration and with our COC NCG020057.)
10/l/07 - Permittee's letter request for either rescission or No Exposure (note that
he did not submit the No Exposure NOT form, just a letter request - I'ts my opinion
that we or you need the NOI form in order to grant any No Exposure request.)
7/14/08 - Jeff's email to Bradley with a second request for permit rescission at
GM#2.
10/7/08 - Jeff's third request for a rescission (and second request for No Exposure,
as an alternative; again, no NOI for the No Exposure request).
11/17/08 - You fielded a call from Jeff, I presume, asking about the rescission, and
emailed us to ask the status.
I picked up this file today, and in a background search I see a newspaper article (Jan
28, 2009) in the Mitchell News -Journal noting layoffs and closings at several of
Unimin's facilities in the area: closing Crystal Plant in Spruce Pine, layoffs at Red
Hill plant, layoffs at the Quartz/Feldspar plant in Spruce Pine. But, no mention of
the Green Mountain #1 plant (a mine with a DLR permit) or the GM#2 plant.
I've gone back to the federal rule, the SIC code book, the DLR mining permit database,
and Starr's description of site activities to see what should happen at this site.
(I've also placed a call to Jeff, but have not heard back from him yet. It's possible
he's not even there anymore, or that he is on furlough, given the circumstances
reported in the MNJ.) Here's what I think should be considered:
1. The DLR does not have this site under a mining permit. Typically, if DLR doesn't
think they are a mine, neither do we. Why they asked for coverage under NCG02 three
times over 12 years is open to conjecture. Maybe we told them to. Maybe they were
contemplating mining on the site. There's no record in our files on this point. But,
we need to get our permitting consistent with the circumstances on the ground now.
2.' As to continued coverage under NCG02. We are compelled to cover under NCG02 any
facility with an SIC code of 14. BIMS shows this facility as SIC1423, mining or
quarrying Crushed and Broken Granite. That's not what they do here, either at GH#i,
or especially at GM#2. So, it looks like our original SIC code is no longer (or
ever?) the SIC of choice. So, as we currently understand the site circumstances,
SIC1423 does not pertain.
3. Further as to continued coverage under NCG02: Since GM#2 receives material from a
remote mining site (GM#1), it appears to me to be excluded from the description of SIC
of 3 4/3/2009 6:28 PM

Jnimin Green Mountain Plant #2
Major Group 14, by virtue of the nature of olivine (olivine is used as a component of
Green Sand, a mold material used in foundries casting aluminum, ie it's a component of
a refractory material) and by virtue of the following wording in Major Group 14
describing similar -looking activities that are categorized elsewhere, "Establishments
primarily engaged in crushing, pulverizing, or otherwise treating earths, rocks, and
minerals mined in Industry Group 145... not in conjunction with mining or quarrying
operations, are classified in Manufacturing, Industry 3295."
- - Note that (olivine mining) is specifically identified in category SIC1459, meaning
that remote facilities that (process olivine) are not SIC14, but SIC3295.- -- -
Going to SIC3295 for corroboration, I see, "Minerals and Earths, Ground or Otherwise
Treated Establishments operating without a mine or quarry and primarily
engaged in crushing, grinding, pulverizing, or otherwise preparing... refractory
minerals."
4. So, to me the question comes down to, how much "crushing, grinding, pulverizing, or
otherwise treating" is going on at GM#2?
- If GM#2 has any crushing, grinding, or pulverizing (obviously) Ott any segregation,
culling, washing, sizing, - or screening, as evidenced by either a rejects pile, or
differentiation of interim products prior to shipping out, then I thank that meets the
intent of "otherwise preparing" the refractory minerals (the olivine). For example,
is there a hopper with a screen in the bag loading operation? Then I think the
screened material (rejects) establishes that "otherwise preparing" the minerals is
taking place at GM#2. If this represents the activity at GM#2, then SIC3295 applies,
and the facility needs our General Stormwater Permit, NCG07, which covers-SIC32.' In
this scenario, we will be quick to rescind their permit for GM#2, but only after they
apply for NCG07. My suspicion is that GM#2 probably does have some sort of material
preparation activities as part of the bagging and loading operation. Starr's report
that no crushing or wet processing is occurring at the site is encouraging news, but I
think it does not fully establish that no preparation at all is occurring. [[OUTCOME
1 = new permit under NCG07, only upon receipt of NOI.]]
- On the other hand, if there really isn't any of this "otherwise preparing" the
olivine as described above, then I think the facility falls outside of the NPDES
permitting program, and we should rescind their permit, as per their request. I
intend to question Jeff on just this point when/if I get to speak to him. [[OUTCOME 2
rescind NCG020057, only upon Jeff's corroborating report of site activities.]]
- There is a third outcome, based on Starr's recommendation that the facility might
qualify for No Exposure. If the facility is captured by the NPDES Stormwater
permitting program as per the rationale for OUTCOME 1, but there truly is no exposure
of industrial materials or processes on the site, then No Exposure may be granted.
But, Unimin has to apply for it via the NCI form, not just by letter request. This is
important because the form contains legal .language specifically binding the
applicant. That legal language is not present in his informal letter request.
[[OUTCOME 3 = No Exposure Exclusion from permitting, only upon NOI receipt.]]
I need more information, which I am seeking from Jeff, via phone message. I'll follow
up Monday with an email.
Presently, my inclination is to deny the rescission request on this basis:
a) Can't proceed to OUTCOME 1 without an NOI for NCG07.
b) Can't institute OUTCOME 2 without further confirmation that no "otherwise
preparing" is going on, I'm uncomfortable rescinding without. Note also, that the
permittee has only referenced Starr's conclusions. He has not provided a
corroborating rationale that establishes HIS responsibility for the determination.
c) Can't institute OUTCOME 3 without an NOI for NCGNE.
I'll hold this for about a week, to give time for Jeff to respond to my attempts to
contact him. Advise me if you think more time would be better. At that time, I'm
going to deny the request for rescission, unless Jeff or ARO provides 'information to
the contrary.

Unimin mothballing Crystal Plant
Print Page
�Vcducsd.�y, January _ri, _oot)
Company also laying off employees at Red Hill plant, says employees will be back when conditions improve
Wesley Brown
News -Journal Staff
Unimin Corporation in response to a decrease in orders due to the worldwide economic recession is shutting
down their Crystal Plant in Spruce Pine and is laying off workers at their Red Hill plant.
"We are going to be mothballing the plant due to slow business conditions from the worldwide economic
recession," Unimin Execution Vice President Joe Shapiro said.
"We are closing it temporarily. We expect to reopen it when business conditions improve, and we do expect
business conditions to improve."
According to Shapiro, the plant, which has a total 47 employees (40 hourly and seven salaried) is laying off all of
the hourly employees.
Most of the lay-offs were effective Jan. 23. The remaining workers not laid off in January will be kept until
February so the company can perform an orderly shut down of the plant.
The seven salaried employees at the Crystal Plant are being reassigned to facilities in Mitchell and Avery counties
and will continue to work for the company.
At their plant in Red Hill, which has 73 employees (10 salaried and 63 hourly), the company is laying off 13
hourly employees effective Jan. 23 through Jan. 25, depending on which job the employee performs.
No layoffs are being made at the Schoolhouse Plant in Spruce Pine.
Shapiro said that the lay offs are temporary and expects to hire the employees back.
"When the plant reopens, and it will reopen, we expect to be bringing people back," Shapiro said.
Before these moves, the company permanently laid off 30 of the 46 hourly employees at the Quartz/Feldspar
plant in Spruce Pine that caught fire Nov. 29. The remaining 16 employees were kept and reassigned to different
facilities.
Those that were permanently laid off met in groups with Chris Silvers, director of the Employment Security
Commission's Spruce Pine office, on Thursday Jan. 22 to discuss job options and enroll in Mayland Community
College's Workforce Investment Act program.
Silvers also said that there is not a whole lot going on in the local job market.
"Our advice is start seeking work in the fields that you have skills," Silvers said. "The best thing to do at this
point is to let a network of friends, family, or neighbors know you are seeking work."
