Section 1. Facility Activities and Process:
SCM Metal Products, Inc. is a facility that produces copper powder, copper oxide, tin powders,
antimony powder, and Cubond Brazing Paste for industrial applications. Flammable materials are stored
outside under roof and in secondary containment. Water in a bioretention cell infiltrates into the ground,
however, if there is ever any overflow, the water for the riser in the bioretention cell is piped to Outfall
SW001.
Significant changes at the facility since the last permit renewal include:
• Brazing manufacturing process was moved from an outside building into the main facility in
March 2013
• Most additives are stored indoors except some drums of flammable liquids (required to store
outdoors); Drums are stored on secondary containment pallets and covered with tarps.
• New process added April 2019: antimony ingots processed into antimony powder(crushing
ingots, grinding/milling and screening)
• Former drum crusher was decommissioned and removed in 2018; Empty drums are now
exchanged with the chemical vendor
• Catalyst process that was in the TL#3 room was decommissioned and all equipment was
removed in December 2021
• Tin,NuTin, and Bismuth processes commissioned in September 2022, producing tin powder, tin-
copper alloy powders, and bismuth powders through air atomization and screening.
o Tin manufacturing previously discontinued December 2013 (moved to another location)
Page 1 of 8

o Bismuth production will include the melting of bismuth ingot and air atomization of the
molten metal to create bismuth powder, and screening operations
o NuTin process will include the melting and air atomization of a 90/10 tin/copper mixture;
resulting powder will include dry handling operations such as screening
• There are plans to install a water copper process in the main production area and a continuous
belt reduction furnace during 2022 Q4
o As a part of this construction, the wastewater pretreatment system been moved to the
Brazing Manufacturing Process area. This will include moving the process tank outside,
near the current storage tank. This tank will be installed inside of a secondary
containment bunker.
o Per information provided 10/25/2022: The process tank being moved outside is part of
the non-process wastewater pretreatment system. This is similar to the large wastewater
storage tank that receives wastewater from the employee shower drains, restroom sinks,
and laboratory sinks. The water from these drains is collected in the large wastewater
storage tank, then pumped into the process tank. Wastewater from the smaller process
tank is then run through a series of 72 membrane filters, which is then run through a resin
bed filter prior to being discharged to the sanitary sewer. The location of the process tank
will be in close proximity to the existing large wastewater storage tank and located inside
a concrete secondary containment.
• Per email communication dated 9/22/2022, outfall SW003 was added in September 2011.
Outfall SW001:
Drainage area contains a parking area, storage pad, copper production warehouse, production plant
warehouse, a bioretention pond, new pallets storage, scrap materials, scrap metal,process equipment
storage, liquid hydrogen storage and loading/unloading operations, copper storage area, slag material from
melt furnace skimming operations,processing of antimony ingots into powder, air atomization of tin, tin-
copper alloy, and bismuth, dumpsters,trash compactor, oil drum storage building, ethylene glycol and SCM
mix storage,waste oil storage tank,maintenance shop, a cooling tower, oil storage building, and bulk storage
tanks for argon,propane, liquid oxygen, and liquid nitrogen.
Outfall SW002:
Drainage area contains the road providing access to the manufacturing areas of the plant parking lot,
administrative offices, loading/unloading area, and R&D lab area. The primary source of storm water
contamination in this area is through accidental spills that could occur during transport of raw materials
and wastes.
Outfall SW003:
Drainage area contains vegetated areas, a parking lot, the Microbond building,production of Cubond®
Brazing paste, storage of tin powders, a wastewater treatment tank, and a wastewater process tank. The
outfall is a settling device which retains rainwater to allow solids to settle prior to being discharged.
Why Industrial Sites with Stormwater are Subject to a Permit: Federal NPDES regulations define
stormwater discharge associated with industrial activity in 40 CFR §122.26 (b)(14) as: "the discharge
from any conveyance that is used for collecting and conveying storm water and that is directly related to
manufacturing,processing or raw materials storage areas at an industrial plant. The term does not
include discharges from facilities or activities excluded from the NPDES program under this part 122.
For the categories of industries identified in this section, the term includes, but is not limited to, storm
Page 2 of 8

water [sic] discharges from industrial plant yards; immediate access roads and rail lines used or traveled
by carriers of raw materials, manufactured products, waste material, or byproducts used or created by
the facility; material handling sites; refuse sites; sites used for the application or disposal of process
waste waters (as defined at part 401 of this chapter); sites used for the storage and maintenance of
material handling equipment; sites used for residual treatment, storage, or disposal; shipping and
receiving areas; manufacturing buildings; storage areas (including tank farms) for raw materials, and
intermediate and final products; and areas where industrial activity has taken place in the past and
significant materials remain and are exposed to storm water. For the purposes of this paragraph, material
handling activities include storage, loading and unloading, transportation, or conveyance of any raw
material, intermediate product, final product, byproduct or waste product. The term excludes areas
located on plant lands separate from the plant's industrial activities, such as office buildings and
accompanying parking lots as long as the drainage from the excluded areas is not mixed with storm
water [sic] drained from the above described areas."
Section 2. Monitoring Information and Compliance History:
• May 2012 to March 2022,benchmarks exceeded for:
o SW001: TSS Ix, Zinc 7x, Copper 23x
o SW002: Copper 23x
o SW003: TSS Ix, Copper 23x
• Copper was exceeded for every outfall for every sampling point provided, however, Tiered
Response was not implemented by the permittee.
• Pe an inspection letter dated 8/23/2011, SW001 is representative of all 3 outfalls
• On 11/4/2021, it's estimated 800 to 900 gallons of cooling water discharged to SW001 through
storm drains. The cooling water is non-contact cooling water that is treated with a corrosion
inhibitor at a concentration of 25ppm.
• Downstream of the discharge location,Northeast Creek(SW001 receiving stream) is impaired
for turbidity, copper, and zinc. During previous permit renewals, the City of Durham had
concerns about air emissions from this facility potentially contributing to the degradation of the
stream.
• Permit file history for previous permits shows DEQ staff concerns over copper at the facility and
implementing BMPs to prevent pollution to Northeast Creek.
o Lots of discussion and meetings between DEQ and SCM staff
• Per an email from Raleigh Regional Office staff(dated 12/13/2022),based on the December
2022 inspection, copper dust was everywhere, with a layer inside the facility(so much that the
RRO inspector asked if it was safe to breath in). RRO staff stated the biggest issue seemed to be
the copper getting tracked out by workers who are leaving doors open and running equipment
through the dust,but that all BMPs were being implemented at some level.
Section 3. Proposed Monitoring for Stormwater Discharges:
The Division considered potential pollutants from past and present industrial activities and data was
submitted for May 2012 to March 2022. Quantitative sampling included pH, TSS, copper, and zinc.
Parameters are based on potential pollutants in the drainage area, sampling results, and in some cases,
dependent upon future activities (e.g., ash removal through the drainage area). Below is a table of the
proposed monitoring for each outfall at the SCM Metal Products, Inc. site.

Stormwater Benchmarks and Tiered Response: Rather than limits,North Carolina NPDES
Stormwater permits contain benchmark concentrations. Stormwater benchmarks are numerical action
levels for stormwater monitoring. Benchmarks are not effluent limits, and benchmark exceedances are
not permit violations. Benchmarks provide facilities a tool for assessing the significance of pollutants in
stormwater discharges and the effectiveness of best management practices (BMPs). Benchmark
concentrations are intended as guidelines for the facility's development and implementation of the
Stormwater Pollution Prevention Plan (SWPPP).
Benchmark exceedances require the permittee to increase monitoring, increase management actions,
increase record keeping, and/or install stormwater BMPs in a tiered program. The permit establishes a
tiered approach to specify actions the permittee must take in response to analytical results above
benchmark concentrations. The tiered structure of the permit provides the permittee and DEMLR wide
flexibility to address issues that may arise with one or more parameters and/or outfalls.
Page 4 of 8

Metals benchmarks are calculated to mimic acute water quality standards and with the guidance of
DWR. NC DWR follows established federal procedures for calculating acute standards when developing
the benchmarks. Just like the acute standards, metals benchmarks normally reflect one half of the
calculated Final Acute Value (the "1/2 FAV"). In most cases, translation into total recoverable values is
based on an assumed hardness of 25 mg/L and a total suspended solids (TSS) concentration of 10 mg/L.
Acute standards protect aquatic life from negative impacts of short-term exposure to higher levels of
chemicals where the discharge enters a waterbody. The Stormwater Permitting Program applies this
approach because of the ephemeral nature of rainfall events.
The Division may evaluate results to determine if a smaller suite of parameters for some outfalls is
adequate to characterize potential pollution or BMP effectiveness. For example, one or more metals or
other parameters may serve as an adequate tracer for the presence of ash pollution during disturbance or
ash removal in specific drainage areas at this site. For parameters that do not have a stormwater
benchmark, the Division may develop a benchmark value if appropriate toxicity data become available
or if rising trends in concentrations suggest a persistent source.
A summary of the benchmarks in the draft permit, and their basis, is below:
Parameter Benchmark Basis
Total Suspended 100 mg/L National Urban Runoff Program(NURP) Study, 1983
Solids TSS
H 6 s.u. —9 s.u. NC Water Quality Standard(Range)
Non-Polar Oil & Review of other state's daily maximum benchmark
Grease 15 mg/L concentration for this more targeted O&G;NC WQS that
EPA Method 1664 does not allow oil sheen in waters
SGT-HEM
COD 120 mg/L BPJ; Generally found at levels 4x BOD5 in domestic
wastewaters
Total Nitrogen 30 mg/L TKN+Nitrate+Nitrite Benchmarks (Expressed in mg/L of
N
Antimony 340 µg/L 1/2 FAV
Copper Total 10 /L Acute Aquatic Criterion, %2 FAV
Zinc Total 126 µg/L Acute Aquatic Criterion, 1/2 FAV
Stormwater Pollution Prevention Plan: The proposed permit conditions reflect the EPA and NC's
pollution prevention approach to stormwater permitting. The Division's maintains that implementation
of Best Management Practices (BMPs) and traditional stormwater management practices that control the
source of pollutants meets the definition of Best Available Technology (BAT) and Best Conventional
Pollutant Control Technology(BCT). The permit conditions are not numeric effluent limitations but are
designed to be flexible requirements for implementing site-specific plans to minimize and control
pollutants in stormwater discharges associated with the industrial activity. Title 40 Code of Federal
Regulations (CFR) §122.44(k)(2) authorizes the use of BMPs in lieu of numeric effluent limitations in
NPDES permits when the agency finds numeric effluent limitations to be infeasible. The agency may
also impose BMP requirements which are "reasonably necessary" to carry out the purposes of the Act
under the authority of 40 CFR 122.44(k)(3). The conditions proposed in this draft permit are included
under the authority of both of these regulatory provisions. In essence, the pollution prevention and BMP
requirements operate as limitations on effluent discharges that reflect the application of BAT/BCT.
Page 5 of 8

Flexibility in Tier Responses: Tier Two actions provide an opportunity for the permittee to propose an
alternative monitoring plan for approval by the Region:
• 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.
• If pursuing the alternative above after two consecutive exceedances, the permittee may propose
an alternative monitoring plan for approval by the Regional Engineer.
The permit therefore allows the permittee to petition the Regional Office for monitoring changes sooner
than Tier Three (upon any four benchmark exceedances) and gives guidance on one option to take. For
example, the permittee may request that mercury only be monitored semi-annually under the tiers, or
that only parameters over the benchmark be monitored more frequently. In this way, changes to the
monitoring scheme for any outfall could be handled outside of a permit modification.
Other Proposed Requirements:
• It is standard for Stormwater Pollution Prevention Plan(SWPPP)requirements to include an
annual certification that stormwater outfalls have been evaluated for the presence of non-
stormwater discharges, and if any are identified, how those discharges are permitted or otherwise
authorized.
• Requirement to submit a request for permit modification if the facility identifies or creates any
new outfalls, removes outfalls, or alters any drainage area that changes potential pollutants.
• The Division expects the permittee to apply best professional judgment and consider the safety
of its personnel in fulfilling sampling obligations under the permit.
• Federal regulations require electronic submittal of all discharge monitoring reports (DMRs). If a
state does not establish a system to receive such submittals, then permittees must submit DMRs
electronically to the EPA.
• Quarterly QualitativeNisual Monitoring to assure regular observation of outfalls throughout
year.
Section 4. Changes from previous permit to draft:
• Monitoring increased from semi-annually to quarterly for all parameters (qualitative and
quantitative)
• "No discharge" clarifications made
• eDMR requirement added
• Feasibility study requirement removed per updated stormwater program requirements
• Boilerplate language moved into body of the permit; boilerplate no longer attached
• Monitoring for total hardness added for all outfalls as monitoring for hardness dependent metals
is required
• Benchmarks updated for parameters per guidance from DWR Standards group on stormwater
benchmarks
• Monitoring for COD added as a potential pollutant indicator due to presence of materials stored
onsite
• Monitoring for total nitrogen added as liquid nitrogen is stored onsite
• Monitoring for antimony added as manufacturing has been added
• BMP permit condition updated

Section 5. Changes from draft to final:
• None
Section 6. Discussions with the Facility and Regional Office:
• Initial contact with facility: 9/12/2022
• Initial contact with Regional Office: 9/16/2022
• Draft sent to CO peer review: 1/23/2023
• Draft sent to Regional Office: 1/24/2023
• Final permit sent for supervisor signature: 5/17/2023
Section 7. Comments received on draft permit:
• Michelle Woolfolk(City of Durham; via email 3/27/2023): The City has no comments. We do
have questions regarding the use of benchmarks, but that is more for the state.
• Permittee representative (via phone 4/14/2023): Permittee does not think they will be able to
meet copper and zinc benchmarks (were not in last permit); permittee may request a
stepwise/drop down in benchmark levels over permit term or a compliance schedule so they can
get extra controls on copper; Permittee may request ROS potentially.
• Jonathan White (SCM Metal Products, Inc.; via email 4/28/2023; summarized here):
o Given historical data, and despite recent and planned efforts to reduce discharges, it is
difficult to predict when SCM may be able to achieve these benchmarks. It is therefore
unreasonable for NCDEQ to impose a permit with unattainable benchmarks. Hardness
and site-specific considerations should be accounted for to have a tailored approach that
reflects a facility-specific nature in developing benchmarks.
■ DEMLR Response: Stormwater benchmarks are not based on the type of permit
issued, but are developed in conjunction with the DEQ DWR Classifications and
Standards Branch. All general and individual industrial permits issued by the
Stormwater Permitting Program use the same benchmarks for pollutants of
concern for a specific facility or industry. Different benchmarks for different
facilities/permits are not permitted.
o In lieu of the tier structure proposed in the draft permit, SCM proposes that DEMLR
include a permit requirement that SCM develop a stormwater controls enhancement plan,
to be approved by DEMLR, that commits SCM to develop and implement enhanced
stormwater controls under a reasonable time schedule.
■ DEMLR Response: Tiered Response is a Stormwater Permitting Program
requirement of all individual industrial permits. Therefore, Tiered Response will
remain in the permit as drafted.
o In place of a Total Antimony benchmark, SCM proposes inclusion of Total Antimony in
quarterly sampling of Outfall SW002, as the stormwater runoff from the antimony
process area discharges only to Outfall SW002.
■ Follow-up clarification(Westley Riscili via email 5/16/2023): You are correct.
Stormwater runoff for the area in which the antimony process is located does in
Page 7 of 8

fact discharge to SW001, as indicated on the site map. The site map that was
provided on October 7, 2022 is correct.
■ DEMLR Response: Monitoring for Total Antimony will remain for all outfalls as
access roads are throughout the site, with potential tracking from vehicles or other
means, and there has been previous concerns regarding potential air deposition.
As a stormwater benchmark exists for Total Antimony, the benchmark will
remain in the permit.
o The draft permit cover letter indicates that the Feasibility Study was removed, yet it is
still referenced in Part E of the draft permit.
■ DEMLR Response: This was an oversight and erroneously not removed from the
permit. The reference to the Feasibility Study will be removed.
o DEMLR also added benchmarks for Non-Polar Oil & Grease, Chemical Oxygen
Demand, and Total Nitrogen, citing to no supporting logic. SCM urges DEMLR to tailor
the final permit to SCM's facility, remedy the inconsistencies, and provide support for
the additional parameter benchmarks.
■ DEMLR response: Monitoring for Non-polar Oil & Grease is required
monitoring for all individual industrial permits and, as stated in the draft permit, is
only required for drainage areas that use>55 gallons/month of oil on average per
EPA Method 1664 (SGT-HEM). Monitoring for Chemical Oxygen Demand and
Total Nitrogen were added to the permit due to the type of materials stored onsite.

Good morning,
After reviewing the comments submitted on the draft permit, I have one question.You state "stormwater runoff from
the antimony process area discharges only to Outfall SW002." However, in information you provided October 7, 2022,
the antimony processing area is shown as a part of Outfall SWO01 (see attached). Please confirm whether the
information in the attached site map is accurate. If it is not accurate, please provide an accurately updated site map as
soon as possible.

Good morning,
I am with the NC DEQ Stormwater Permitting Program. I am working on renewing the stormwater permit for SCM Metal
Products, Inc. (NCS000050), located in Durham County at 2601 Weck Drive. According to our permit files,the City of
Durham was very involved in the renewal of the last stormwater permit for this facility. Is this permit still of interest to
the City of Durham? I am preparing the updated draft permit for public notice and am reaching out to confirm if the City
would like to provide comments before I submit the draft to public notice. If you are not the correct contact for this
request, can you please point me in the right direction?

Looking at Laurens inspection report for the facility, she gives them 5 stars for PP&G and their BMP's. I don't see any
deficiencies noted or recommendations, other than continued sweeping, so it appears they do everything possible to
control pollutants from entering the stormwater and leaving the site.This may be one of those sites where we need to
make a judgement call. If there needs to be a conversation, let me know.

SCM has many copper exceedances (basically every sample period reviewed for permit renewal). Zinc has a couple of
exceedances but is not a chronic problem. Lauren's inspection report indicated the facility does have good BMPs in
place, but that copper is still getting out of the facility. Is there anything I need to add to SCM's BMP permit condition?
Or should we just tell them they need to look into other options to stop copper being tracked outsie?
How can we assess/confirm whether air deposition is coming from SCM onto Wolfspeed (as Woflspeed claims)?What
do we need to do/review to move the SCM permit and Wolfspeed relief request forward?

If they are sampling all their outfall areas and copper is not an issue, I don't think there is anything else beyond what is
required and actively being done that would need to be added. If they are getting high readings,they should have their
consultant investigate other options to reduce the tracking of copper.

If the permittee that believes that the SCM facility is the cause of their high copper sample results can sample the flow
coming onto their site from the SCM facility to confirm that the issue originates there,we can look at providing tier
relief, if they provide their proof.

Lauren conducted an inspection this week on the SCM facility as part of the renewal. Based on the inspection report, it
sounds like they have good BMPs in place but that copper does get tracked outside the processing facility from feet and
tires. Is there anything we should add to the permit as another facility is citing SCM for their issues?There is already a
BMP condition in the permit to address copper issues:
The Permittee shall implement the following BMPs at this facility and shall include these BMPs in the facility's SWPPP:
(a) The Permittee shall ensure entryways and loading areas near manufacturing areas where dust track-out
occurs are swept daily, and that cleaning procedures are conspicuously posted within the affected work
areas.
(b) The Permittee shall ensure routine evaluations by employee task groups of BMPs intended to reduce
copper or other metal dust exposure and shall identify practices or areas in need of improvement.
(c) The Permittee shall implement BMPs to reduce fugitive dust, including but not limited to:
i. Moving fork truck and sweeper maintenance indoors;
ii. Improving preventative maintenance for dust collectors; and
iii. Handling and storing glycerin in reusable containers.
For BMPs that have already been implemented, the Permittee shall ensure those practices are maintained as long
as they effectively reduce fugitive dust.
(d) The Permittee shall maintain an Operation and Maintenance (O&M)Plan for any structural BMPs, such
as bioretention cells. The O&M Plan must indicate actions that shall be taken, specific criteria used for
determining when those actions shall be taken, and who is responsible for those actions. The plan must
clearly indicate the steps that shall be taken and who shall be responsible to restore the structural
stormwater BMP systems to design specifications if a failure occurs and must include acknowledgement
by the responsible party.
(e) For areas the Permittee has determined to be primary contributions to copper or other metals in runoff
from this facility, either through the Monitoring Plan approved by the Division in May 2007 or by other
means, the Permittee shall continue to:
3

i. Assess BMPs intended to reduce dust release and track-out from industrial activities;
ii. Improve dust collection efficiency;
lit. Reduce other sources of copper or other metals contamination; and/or
iv. Capture and treat the runoff with engineered controls.
The Permittee shall maintain current information about selected BMPs, their implementation, and
effectiveness in reducing metals concentrations in the Stormwater Pollution Prevention Plan. That
information should include reference to DWR stormwater benchmark concentrations for total
recoverable copper and zinc, currently 10 µg/L and 126 µg/L. All or part of this information should be
incorporated into the Feasibility Study component of the Stormwater Management Plan (see Part B
Section B-8 of Stormwater Pollution Prevention Plan requirements) as appropriate.

Good morning! I am going through all my emails from when I was out. I definitely don't think they can justify tier relief
for copper,the dust was everywhere.There was a layer of it inside the facility, so much so,that I asked if it was safe to
breath it in.
Also,they are having their duct work replaced right now to improve collection efficiency. I saw evidence that they are
implementing all their required BMPs on some level.The biggest issue seemed to be the copper getting tracked out by
workers who are leaving doors open and running equipment through the dust.
They have drop inlets in the parking lot that drain to their bioretention cell, I don't know if anything can be added to
keep the copper from getting into those?

Subject: RE: [External] Request for Relief from Advance Tier Response for Copper and Zinc
SCM has many copper exceedances (basically every sample period reviewed for permit renewal). Zinc has a couple of
exceedances but is not a chronic problem. Lauren's inspection report indicated the facility does have good BMPs in
place, but that copper is still getting out of the facility. Is there anything I need to add to SCM's BMP permit condition?
Or should we just tell them they need to look into other options to stop copper being tracked outsie?
How can we assess/confirm whether air deposition is coming from SCM onto Wolfspeed (as Woflspeed claims)?What
do we need to do/review to move the SCM permit and Wolfspeed relief request forward?

If they are sampling all their outfall areas and copper is not an issue, I don't think there is anything else beyond what is
required and actively being done that would need to be added. If they are getting high readings,they should have their
consultant investigate other options to reduce the tracking of copper.
If the permittee that believes that the SCM facility is the cause of their high copper sample results can sample the flow
coming onto their site from the SCM facility to confirm that the issue originates there, we can look at providing tier
relief, if they provide their proof.

Subject: RE: [External] Request for Relief from Advance Tier Response for Copper and Zinc
Lauren conducted an inspection this week on the SCM facility as part of the renewal. Based on the inspection report, it
sounds like they have good BMPs in place but that copper does get tracked outside the processing facility from feet and
tires. Is there anything we should add to the permit as another facility is citing SCM for their issues?There is already a
BMP condition in the permit to address copper issues:
The Permittee shall implement the following BMPs at this facility and shall include these BMPs in the facility's SWPPP:
(a) The Permittee shall ensure entryways and loading areas near manufacturing areas where dust track-out
occurs are swept daily, and that cleaning procedures are conspicuously posted within the affected work
areas.
(b) The Permittee shall ensure routine evaluations by employee task groups of BMPs intended to reduce
copper or other metal dust exposure and shall identify practices or areas in need of improvement.
(c) The Permittee shall implement BMPs to reduce fugitive dust, including but not limited to:
i. Moving fork truck and sweeper maintenance indoors;
ii. Improving preventative maintenance for dust collectors; and
iii. Handling and storing glycerin in reusable containers.
For BMPs that have already been implemented,the Permittee shall ensure those practices are maintained as long
as they effectively reduce fugitive dust.
(d) The Permittee shall maintain an Operation and Maintenance (O&M) Plan for any structural BMPs, such
as bioretention cells. The O&M Plan must indicate actions that shall be taken, specific criteria used for
determining when those actions shall be taken, and who is responsible for those actions. The plan must
clearly indicate the steps that shall be taken and who shall be responsible to restore the structural
stormwater BMP systems to design specifications if a failure occurs and must include acknowledgement
by the responsible party.
(e) For areas the Permittee has determined to be primary contributions to copper or other metals in runoff
from this facility, either through the Monitoring Plan approved by the Division in May 2007 or by other
means, the Permittee shall continue to:
i. Assess BMPs intended to reduce dust release and track-out from industrial activities;
ii. Improve dust collection efficiency;
iii. Reduce other sources of copper or other metals contamination; and/or
iv. Capture and treat the runoff with engineered controls.
The Permittee shall maintain current information about selected BMPs, their implementation, and
effectiveness in reducing metals concentrations in the Stormwater Pollution Prevention Plan. That
information should include reference to DWR stormwater benchmark concentrations for total
recoverable copper and zinc, currently 10 µg/L and 126 µg/L. All or part of this information should be
incorporated into the Feasibility Study component of the Stormwater Management Plan(see Part B
Section B-8 of Stormwater Pollution Prevention Plan requirements) as appropriate.

Permit: NCS000050 Owner-Facility:SCM Metal Products, Inc.
Inspection Date: 12/07/2022 Inspection Type:Compliance Evaluation Reason for Visit: Routine
Inspection Summary:
Inspection was in response to permit renewal. Information included in the application is accurate. The application states that
the tin manufacturing process has been discontinued.Tin manufacturing was brought back. The facility has also added
some special metals manufactuing, like antimony, bismuth,nuTin, etc. Antimony and tin dust are combustable, so
manufacturing is contained and there should be no transfer of the dusts around the facility. The copper manufactuing that
takes place onsite does generate a lot of dust. There is a dust residue that gets tracked outside the facility by foot and
loader traffic. The facilty is also partially under construction so BMPs that have previously been regularly used are not as
effective, like tacky matts to prevent the copper dust being tracked outside. There is a dust collection system and the
copper dust is collected in an exterior bag house. The copper dust is deposited in a bag and the bag is monitored multiple
times a shift to prevent over flow. There is still a risk of exposure of the copper dust to stormwater if there is a bag
malfunction. Copper dust was observed tracked outside. It should be noted that the facility has an impressive list of BMPS
that are regularly implemented to deal with the dust. There are tanks and other materials stored outside at the rear of the
facility. Everything appeared to be stored correctly. There are several drop inlets in the paved lot at the rear of the facility
where there is storage. The drop inlets drain to an onsite bioretention cell.Water in the bioretention cell infiltrates into the
ground. If there is ever any overflow, the water for the riser in the bioretention cell is pipes to outfall 1. The facility uses a
street sweeper in the back parking lot to control copper dust. Used oil drums are stored under cover and in propper
secondary containment in the back lot. Construction materials are also stored temporarily in this back lot.
I recomend the site map be updated to show the bag houses, outdoor storage of tanks, used oil, raw materials, etc.
Continue sweeping activities to address the copper dust tracked into the back lot.

RE: NPDES Permits NCG030433 and NCG030541
Request for Relief from Advanced Tier Response for Copper and Zinc
Dear Mr.Valentine:
Wolfspeed, Inc. (formerly Cree, Inc.) operates under General Stormwater Permit NCG030000 for Metal
Fabrication. This General Stormwater Permit was renewed effective 07-01-2021. It was revised to increase
routine sampling from semi-annually to quarterly. It also rescinded Wolfspeed's Letter of Relief from
Advanced Tier Response for Copper and Zinc granted by DEMLR on 09-24-2014. Due to the increased
sampling frequency and the lack of relief from advanced tier response for copper and zinc exceedances,
Wolfspeed now has several stormwater outfalls at both locations requiring Tier III response.
Wolfspeed does not believe the elevated copper and zinc levels originate from the Silicon Drive (DUR) or
Cornwallis Road (RTP) locations based on the following:
• Kymera International (formerly SCM Metal Products, Inc.) is located at 2601 Weck Drive, Research
Triangle Park, NC 27709. The facility smelts copper which could be emiting unregulated concentrations
of copper and zinc to the atmosphere, as reported in their TRI annual report. The copper and zinc may
then be atmospherically deposited to surrounding surface areas such as roofs and parking lots and
"washed"to stormwater outfalls during rain events.
• Copper and zinc compounds are used in wet manufacturing processes at the DUR site. However, the
processes are contained within buildings with no impact to stormwater drains or outfalls.
• Copper and zinc compounds are not used at the RTP site.
• Elevated copper and zinc levels have consistently exceeded the benchmark values in several of the
industrial stormwater discharge outfalls between the two sites. Table 1 and Table 2 (attached) present
the history of copper and zinc exceedances.
• SDO-2,SDO-5, WOLF-1, and WOLF-4 receive the majority of flows from building roofs and paved
surfaces at the respective sites. The copper and zinc values for these outfalls are indicative of
atmospheric deposition.

—k-
Wolfspeed.
• Possible mitigation measures are costly and are not guaranteed to reduce the copper and zinc values
below benchmark.
In summary,Wolfspeed does not see a benefit to continue to perform the costly monthly monitoring at both
Wolfspeed facilities beyond the required quarterly occasions or implement costly mitigation measures.
Based on these reasons and the previous Relief from Advanced Tier Response for CopperandZinc granted by
DEMLR,Wolfspeed respectfully requests to resume quarterly sampling stormwater analytical monitoring for
the remainder of our permit terms for the copper and zinc parameters. Wolfspeed will continue to perform
quarterly qualitative monitoring along with the quarterly analytical monitoring for all required parameter,
and Wolfspeed will continue to follow the Tier I-Tier III process should Wolfspeed's sampling results ever
exceed another parameter besides copper and zinc.
Please contact me at 919-407-6103 should you require additional information.

RE: NPDES Permits NCG030433 and NCG030541
Analytical Monitoring Request and Response to August 1, 2014 Meeting
Dear Mr. Parnell:
It was a pleasure meeting with you and Bethany Georgoulias to discuss options for Cree's stormwater
monitoring for copper and zinc. This letter is to follow up the verbal request made during our meeting
on Friday, August 1, 2014 at NCDENR offices at 3800 Barrett Drive.
I
During the meeting Cree presented reasons why the Cree-Durham and Cree-RTP (Research Triangle
Park)facilities,which have both reached Tier Three status under Part II Section B of our NPDES
permits NCG030433 and NCG030541, should return to semi-annual stormwater analytical monitoring
from Tier Two monthly monitoring. Elevated copper and zinc levels, we feel, are not originating from
the Cree-Durham or Cree-RTP facilities based on the following objective evidence:
• No copper or zinc compounds are used in Cree's manufacturing processes at either location
which could contribute to these levels;
• Cree has performed an extensive review of its buildings and operational areas and no
significant sources of copper or zinc have been identified at either Cree facility that could be
contributing to these levels;
• Elevated copper and zinc levels have consistently exceeded the benchmark values in all seven
Cree-Durham industrial stormwater discharge outfalls and all five Cree-RTP industrial
stormwater discharge outfalls, even though several of these outfalls have on-site drainage areas
that contain no buildings, equipment,vehicles,or other possible sources of copper and zinc.
Further, Cree is aware of a copper smelting plant in the vicinity that could be contributing to these
elevated copper and zinc levels. That facility should be taken into consideration by NCDENR as a
potential source of copper and zinc due to atmospheric deposition.

In summary, Cree does not see a benefit to continue to perform the costly monthly monitoring at both
Cree facilities beyond the required four occasions already completed.
Based on these reasons and on the technical discussion held during our meeting on August 1, Cree
formally asks to resume semi-annual stormwater analytical monitoring for the remainder of our permit
terms for the zinc and copper parameters. Cree will continue to perform semi-annual qualitative
monitoring along with the semi-annual analytical monitoring for all required parameters, and Cree will
continue to follow the Tier One-Tier Three process should Cree's sampling results ever exceed another
parameter besides copper and zinc. If NCDENR agrees, and we are able to perform analytical
monitoring of stormwater discharges this next month, we also respectfully request that the next
samples collected be allowed to satisfy our upcoming fall 2014 reporting period.
In addition, during the August 1, 2014 meeting with you Cree asked for a reduction in the number of
outfalls that require analytical monitoring at both the Cree-Durham and Cree-RTP facilities based on
representative outfall status and in a few cases insignificant drainage from certain outfalls.
Cree will plan to submit a separate formal request for this reduction to NCDENR in the near future.
In the interim please advise Cree on our above request to return to semi-annual monitoring
immediately for both Cree-Durham and Cree-RTP facilities.
Please contact me at 919-407-6101 if you need additional information.

Donna Lazzari

Dear Ms. Lazzari:
In response to your discussions with NCDENR Land Quality Section staff, concerning multiple
exceedances of the benchmark values for zinc and copper, Dave Parnell of the Land Quality
Section -Stormwater staff, conducted a compliance evaluation inspection (CEI) on April 8,
2014. The inspection was conducted to determine compliance with the conditions of your
NPDES NCG030433 Stormwater Permit and to discuss any actions that have been or could be
taken to identify and eliminate potential sources of Zinc and Copper related to facility
operations,
Keep in mind that benchmark exceedances are not limit violations or violations of permit
conditions; however,you are obligated to follow the tiered response actions outlined in your
permit. At the time of the inspection,your facility was found to be in compliance with the
tiered response actions and other conditions of the permit, During the inspection,you are
reported to have relayed to Mr. Parnell that you have been unable to determine the source of
the higher levels of the metals, found at the Silicon Drive outfalls. It is notable in this case,
that CREE does not use copper or zinc in the manufacturing processes and the facility has
conducted extensive reviews of your site for external sources of the metals. Your diligence in
attempting to determine and eliminate the zinc source and your continued communication
with Raleigh Regional Office staff is commendable and is documented back to the April 8
compliance evaluation inspection.

Based on the aforementioned items, DENR Land Quality Section is granting regulatory relief in
the form of a collapsed Tier 2-'Pier 3 response. Upon receipt of this letter, CREE- Silicon
Drive, may resume the permit specified semi-annual analytical monitoring for the remainder
of the current permit term - which ends October 31, 2017. This decision applies only to the
zinc and copper benchmarks, A benchmark exceedance of any other parameter listed in
your permit will trigger the tiered response actions as described in your permit:
You must notify this office, in writing, within five business days if you become aware of any
significant source of zinc or copper at your facility, that has the potential to be exposed to
stormwater. The relief granted in this letter is contingent upon the current industrial
practices at CREE. If industrial practices change and zinc&copper does become a significant
stormwater exposure risk, then this office reserves the right to withdraw this decision and
reinstate the permit specified tiered response or other actions that may be warranted by the
new set of circumstances.
Retain and append this letter to your Stormwater Pollution Prevention Plan (SPPP) or permit.
Should you have questions or comments regarding the CEI or this letter, please contact Dave
Parnell at(919) 791-4200 or [e-mail].

Good morning, Brianna,
The process tank that is being moved outside is part of our non-process wastewater pretreatment system. This is similar
to the large wastewater storage tank that receives wastewater from our employee shower drains, restroom sinks, and
laboratory sinks. The water from these drains is collected in the large wastewater storage tank,then pumped into the
process tank. Wastewater from the smaller process tank is then run through a series of 72 membrane filters,which is
then run through a resin bed filter prior to being discharged to the sanitary sewer. The location of the process tank will
be in close proximity to the existing large wastewater storage tank. This tank is located inside of a concrete secondary
containment. I have attached a site map showing this location. Please let me know if this will suffice, or if you would
prefer a satellite image showing this location.

SIGNIFICANT CHANGES IN INDUSTRIAL ACTIVITIES — Updated 10/7/2022
In March of 2013, the Brazing Manufacturing Process was moved into the main facility from an outside
building. This relocation of this process has helped eliminate the transfer of materials between buildings.
In December of 2013, the Tin Manufacturing Process was discontinued at the RTP facility. This process
was moved to another SCM Manufacturing Plant in Union, New Jersey.
Most additives are stored indoors, with the exception of some drums of flammable liquids, which SCM is
required to store outdoors by the fire department. These drums are stored on secondary containment
pallets and are covered with tarps.
UPDATE SINCE ORIGINAL PERMIT RENEWAL SUBMISSION IN 2016:
In April of 2019, the Antimony process began operations. This process involves crushing antimony
ingots into powder form through a series of jaw crushers, mills, and screening activities. This is a dry
process that is located inside of the main building near the warehouse loading docks.
In December of 2021, the Catalyst process that was located in the TL#3 room was decommissioned
and all equipment was removed.
In September of 2022, the Tin Manufacturing Process was recommissioned, located in the room next
to the Antimony process. The process is currently under Engineering control and has not been
handed over to operations. This is expected to occur in the next week. An additional process for the
production of Bismuth and NuTin Powder is also being commissioned in this room. Bismuth
production will include the melting of bismuth ingot and the air atomization of the molten metal to
create bismuth powder, and screening operations. The NuTin process will include the melting and air
atomization of a 90/10 tin/copper mixture. The resulting powder will include dry handling operations
such as screening. Activities for all of these processes will occur indoors.
There are plans to install a water copper process in the main production area. In addition, a
continuous belt reduction furnace is planned to be installed in the previous TL#3 room. This is
expected to occur in the 4t" quarter of 2022. As a part of this construction, the wastewater
pretreatment system been moved to the Brazing Manufacturing Process area. This will included
moving the process tank outside, near the current storage tank. This tank will be installed inside of a
secondary containment bunker.

Good morning Brianna,
3

I am happy to assist with the requested information. Since our submission of this renewal,there have been some
changes at the facility. Jonathan White (in copy here) is the new Operations Manager. I am still the technical contact for
the facility. We are currently in the process of adding additional processes at the facility. These are both dry processes
in which all handling and processing activities occur indoors. These include the processing of tin and bismuth. None of
these processes should have an impact on the stormwater quality for this facility. Construction for these processes is
currently underway. The next phase of construction will also include some new processing equipment for copper. All
activities for this process will also occur indoors. If you have any questions while I gather the requested information,
please do not hesitate to ask.
Best regards,

Hi Brianna,
No problem. I had the same issue when I initially set up our EDMR. Outfall#3 was not listed for reporting. However,
when I contacted Bethany we were able to get it on there. Please let me know if you need any additional information.

Thank you for the quick response. If you are able to easily find when outfall SWO03 was added to the site, that
would be great. Otherwise, knowing it has been in place since at least 2007 is very helpful.

Hi Brianna,

There is an outdoor H2 storage tank located at the NW corner of the facilities perimeter fence, inside of a fenced area
within the perimeter fence.
A 36" pipe runs approximately 400' N from the underdrain of the bioretention cell towards the property line. The pipe
ends at a weir that then discharges down a riprap channel. Point at which the water leaves the weir is outfall#1.
I will need to review my archive to determine the date of installation for Outfall#3. This outfall is described in our
SWPPP as far back as 2007. It has been in place prior to that.

Westley,
I have a few follow-up questions.
1) Are there H2 storage tanks outdoors on the property?
2) Does outfall SW001 discharge from the bioretention pond?
3) When was Outfall SW003 identified at/added to the facility?Our permit files only discuss outfalls SW001 and
S W 002.

Requested information:
• Confirmation on number of outfalls and associated coordinates;
✓ The number of outfalls and associated coordinates have not changed.
• Confirmation of the receiving stream for each outfall;
✓ The receiving stream for each outfall remains unchanged.
• Description of industrial activity in each drainage area;
2.1 Outfall 1 (Area 1)
Industrial activities, consisting of raw material storage, chemical storage,waste storage, equipment
storage, and loading/unloading operations take place throughout the drainage area of the storm water
outfall. Because of this,the outfall drainage area will be subdivided into the following four sections:
(1)between the copper plant/warehouse building and the west fence line extending to the northwest
fence corner, (2) across the rear of the plant from the northwest fence corner to northeast fence
corner, (3)between the copper plant/warehouse building and the eastern fence, and(4)the general
area between the copper plant/warehouse building and the maintenance building.
2.1 Area 1 Section (1)
The area adjacent to the western fence line is primarily used for storage of new pallets, scrap
materials, equipment that is not in use, liquid hydrogen storage and loading/unloading operations.
The scrap materials consist of scrap metal. The equipment consists of process equipment that is not
in use as well as equipment that is used from time-to-time but temporarily stored in this area until
needed. Three newly commissioned processes reside in this area and are described below.
Adjoining the building is the copper storage area. This area, consisting of a concrete pad, is
completely covered and thus eliminates storm water exposure to the copper metal stored there. Slag
material from melt furnace skimming operations is stored in this area before shipment to a metal
reclamation facility. The southwest corner of the warehouse contains ancillary processes consisting
of the processing of antimony ingots into powder through a series of crushers and mills, and the air
atomization of tin, tin-copper alloy, and bismuth and associated screening operations. Emissions
from these processes are controlled with baghouses and do not have any open discharges to the
outside. A bulk storage tank for Argon is located in this area. There are also waste receptacles such
as dumpsters and a trash compactor in this area. The compactor is located in the truck
loading/unloading area and is mainly used for office trash and used shipping containers. The primary
source of storm water contamination in this area is from the waste materials themselves and residue
on waste materials and equipment that is stored outside.
2.1 Area 1 Section (2)
Located in the area beginning at the northwest fence corner and extending to the maintenance
building are SCM's oil storage building,propane, liquid oxygen and liquid nitrogen bulk storage
tanks. Drums in the oil storage building are stored on containment pallets and are completely
sheltered from contact with stormwater. The contents of the bulk storage tanks contain liquefied
gases that return to a gaseous state at ambient temperature and pressure and therefore do not
constitute a storm water contamination hazard.
Within the area that extends from the east corner of the maintenance building to the northeastern
fence corner is a cooling tower. The main potential for contamination in this area is from chemicals
used to treat the water used in the cooling tower. All chemicals used in the cooling tower are added
to the system inside the building that helps reduce the likelihood of contact with storm water. The
former drum crusher was eliminated from this area in 2018. It had not been used in several years, as
metal drums are now exchanged and picked up by our supplier.
2.1 Area 1 Section (3)
Near the northeast corner of the building is the waste oil storage tank. The waste filter storage bin has
been eliminated from this area, and the filters are now cleaned and stored inside of the maintenance

shop. The waste oil storage tank is located on a concrete secondary containment pad within an
additional secondary containment structure.
2.1 Area 1 Section (4)
The area between the maintenance building and the copper plant/warehouse building is primarily
used for storage of ethylene glycol and SCM mix, which are used in the Cubond process. The
materials are stored in sealed containers with appropriate covers and secondary containment.
2.2 Outfall 2 (Area 2)
Industrial activity contributing to storm water run-off from this area is limited to a
loading/unloading area that adjoins the Research and Development Labs and the road that provides
access to the manufacturing areas of the plant.Therefore, the primary source of storm water
contamination in this area is through accidental spills that could occur during transport of raw
materials and wastes through this area. The occurrence of large spills in this area is considered
unlikely.
2.2 Outfall 3
The industrial activity in this area that could contribute to storm water contamination includes the
production of Cubond®Brazing paste and the storage of tin powders. A waste water treatment tank
located in this area has a sufficiently sized secondary-containment structure.
The industrial activities occur indoors.The only potential source of storm water contamination is
the dust collector located between the copper production area and the Cubond° production area; it
is inspected at regular intervals.
• SIC (NAICS) code;
✓ 331420
• An electronic spreadsheet summarizing all of the monitoring data that has been collected
since the effective date of the current permit;
✓ Spreadsheet is attached in this email.
• Verification that the information in the renewal application is still complete and correct.
✓ Some modifications are required due to the commissioning of new processes. These
will be uploaded separately.
• An explanation of any operational changes since the renewal application was submitted.
✓ The primary changes since the renewal application was submitted are as follows:
• The commissioning of the Antimony Process. This is an ancillary process in
which antimony ingots are processed through crushing and milling into a
powder. The process is contained within the building and is not considered to
be a potential stormwater contamination source.
• The commissioning of the Tin/NuTin/Bismuth processes. These ancillary
processes produce tin powder, tin-copper alloy powders, and bismuth powders
through air atomization and screening. These processes are contained within
the same building and are not considered to be a potential stormwater
contamination source.
• The oil storage location for this facility was moved to an adjacent building to the
Maintenance shop. The floor was sealed, and all drums are contained in the
building on secondary containment pallets. These are not exposed to
stormwater.

• The former drum crusher had not been in use for many years, and in 2018, it
was decommissioned and removed from the site. Empty drums are now
exchanged with the vendor for these chemicals.

Good afternoon Suzanne,
I had submitted a renewal application for our storm water permit in 2016, in which we are still operating under the
parameters of the previous permit as instructed by the state because we have not received the renewal to date. However,
we would like to make a small amendment to that application, as we intend to install a new process onsite in June of this
year. Please see the attached cover letter, along with an amended Significant Changes in Industrial Activities and a site
map showing the location of the new process.
Also, our copier does not produce the best quality copies. Please let me know the supplied attachment is acceptable to
request this change, or the preferred method of submission if this is not acceptable.
I appreciate your help on this matter.

To whom it may concern:
The purpose of this letter is to notify the state of SCM Metal Products' intent to install a new process at our
facility. In 2016 I had submitted a permit renewal form for SCM Metal Products, Inc., permit No. NCS000050.
We have not received the renewed permit to date, and we are currently operating within the parameters of our
previous permit as instructed by the state. However, there is a plan to install a new process in June of this year
in which antimony ingots will be processed into antimony powder. We would like for the state to include this
process in our permit during the renewal process.
This process will include crushing, milling, and screening operations. The process will be located indoors in the
previous location of our tin powder production area, which is no longer in operation. The process will be
connected to a baghouse that will be located outside of the building as a control device for air quality. There are
no floor drains associated with this process that are connected to any of our storm drains. This process will be
located in the area of our storm water site reap that is directed to outfall #1. We do not anticipate any emissions
that would affect storm water quality. We will update our storm water pollution prevention plan accordingly to
include this process.
If you have any questions or require additional information please contact me at
[e-mail], and I can be reached direct at(919) 287-9891.
Sincerely,
Westley Riscili

SIGNIFICANT CHANGES IN INDUSTRIAL ACTIVITIES
In March of 2013,the Brazing Manufacturing Process was moved into the main facility from an outside
building. This relocation of this process has helped eliminate the transfer of materials between buildings.
In December of 2013, the Tin Manufacturing Process was discontinued at the RTP facility. This product is now
produced at a sister facility.
Most additives are stored indoors, with the exception of some drums of flammable liquids, which SCM is
required to store outdoors by the fire department. These drums are stored on secondary containment pallets
and are covered with tarps.
SCM intends to install an Antimony Powder Process at our RTP facility. This process includes the crushing of
antimony ingots,and the grinding/milling and screening of antimony powder. This process is planned to be
installed in June of 2019. The Storm Water Pollution and Prevention Plan will be updated accordingly.

BEST MANAGEMENT PRACTICES
1. A high-efficiency sweeper was purchased for use on the paved area around the copper
production area. The area between the copper production building and the
CuBond®/Maintenance Building receives intensive sweeping. This area is swept twice
per day, as weather conditions permit.
2. The slag storage has been located in the covered pad area. This storage removes this
material from any storm water exposure.
3. The CuBond®dust collector has been enclosed and a clean-up method will be installed to
gather possible spilled material.
4. A corrosion-proof storage tank with secondary containment has been installed for waste
oil storage.
5. Clean out corrugated pipe leading to Outfall 1
6. New style trash dumpster/compactor to minimize rain water entering and washing
through the dumpster. Also, an indicator will be included in the hydraulic system; this
indicator will lead to more efficient use of the dumpster by assuring maximum loading.
Maximum loading will minimize handling.
7. New rules on used pallet and card board disposal. These revisions have lowered the
amount of material in the dumpster. These improvements also minimize dumpster
handling.
8. Rules on material that can be added to the dumpster and different packaging
requirements. CuBond®regularly bags the trash they add to the dumpster.
9. "Tacky Mats" at doorways between the copper production area and the outside area.
10. Fork truck and sweeper maintenance is performed indoors.
11. Preventative Maintenance of dust collectors was improved to include dye inspection of
interior.
12. Glycerin storage has been moved indoors. Additionally, glycerin is stored in re-usable
containers.
13. Written and posted instructions on floor sweeping. Sweeping is accomplished at least
daily.
14. Work Instructions on Dust Collector Media change-out.
15. Implementation of employee task group meetings to elicit and evaluate copper exposure
reduction BMP's.
16. Installation of new equipment to reduction fugitive copper dust emissions.
17. The Dust Control Committee will be revitalized
18. Include Storm Water Prevention awareness as part of Housekeeping Committee
inspections.
19. A major Best Management Practice installed in 2010 was a Bio-Retention Device
servicing the run-off from the paved area between the copper production building and the
Maintenance/Cubond building.
20.The area north of the Maintenance/Cubond building was re-graded and planted to control
run-off.
21. The continued implementation and improvement of dust collector bag change-out
procedures, especially the Shot Furnace and Thin Layer Furnace dust collectors.

22. Different filter media is being used in Dust Collector to determine efficacy
23. Improvement to storm drainage around the"Microbond Building"was completed. This
work is expected to improve silt run-off in Outfall 3. The work was also undertaken to
alleviate flooding conditions in the"Microbond Building."
24. Improvements to erosion control have been implemented in other locations around the
facility. These improvements were undertaken to reduce soil run-off.
25. Cubond®powder is stored indoors.
26. Additional erosion controls have been installed around the Cubond®building(formerly
the Microbond building.)
27. Cubond®paste operations relocated to allow transfer of raw materials and product
without exposure to storm water.
28. Additional erosion control installed.
29. Improved feeders were installed at belt furnaces to minimize fugitive emissions.
30. Cyclones in process area replaced to minimize fugitive emissions.
31. Trees have been planted in the Northwest corner of the property to help with erosion.
32. Used and broken pallets are stored indoors to minimize potential contact of contaminated
pallets with storm water.
33. Outfall 3 was cleared of silt.
34. The corrugated pipe leading to Outfall 1 was cleared of silt.
35. Additional trees have been planted in the Northeast corner of the property to help reduce
erosion.
36. A level spreader was installed in the Northeast corner of the property to help slow storm
water runoff coming from the top of the hill to help ameliorate erosion issues in that area.
This BMP runs North and South, parallel to the fence line on the east side of the property.
37. The earthen swale that runs from the Northeast corner of the property was re-graded, a
silt liner was added to the swale and covered with grade A rip rap to help protect the
swale from erosion.
38. The Bio-retention device located to the west of the hydrogen tank has been cleared of old
vegetation, mulch, and soil, all of which has been replaced to specification of the original
Bio-retention plans.

SIGNIFICANT CHANGES IN INDUSTRIAL ACTIVITIES
In March of 2013, the Brazing Manufacturing Process was moved into the main
facility from an outside building. This relocation of this process has helped eliminate
the transfer of materials between buildings.
In December of 2013, the Tin Manufacturing Process was discontinued at the RTP
facility. This process was moved to another SCM Manufacturing Plant in Union, New
Jersey.
Most additives are stored indoors, with the exception of some drums of flammable
liquids, which SCM is required to store outdoors by the fire department. These
drums are stored on secondary containment pallets and are covered with tarps.
