RE: Stormwater Discharge Outfall (SDO) Monitoring Report
Cree, Inc., 3028 Cornwallis Road, Durham, Durham County, North Carolina
General Stormwater Permit No. NCG030000/COC NO. NCG030541
January — June 2018, WOLF #1, #2, #3, #4, and #5
To Whom It May Concern:
Please find enclosed the semi-annual stormwater Discharge Monitoring Reports (one original and one
copy) for the eight stormwater outfalls located at Cree, Inc., 3028 Cornwallis Road, Durham, Durham
County, North Carolina. The analytical reports were received from the laboratory on May 15, 2018. ESC
Lab Sciences (NC ID #ENV 375) conducted the analyses which completes the first 2018 semi-annual
testing requirements for the Cornwallis Road site.
Discharge samples were collected at every outfall #1, #2, #3, #4, and #5. For the sampled outfalls,
and as in previous reports submitted to DEQ, levels for copper and zinc are above the benchmark
values listed in Table 3 of section 11.13 of our stormwater permit for outfalls #1, #2, #3, #4, and #5 (Cu)
and outfalls #1, #3, #4, and #5 (Zn). In September 2014, Cree was granted an exemption from the
requirement to continue following Tier Two and Tier Three response actions as stated in Section B of
the stormwater permit for these parameters. Cree will continue to monitor these levels throughout the
next semi-annual testing period and report any success in eliminating the elevated levels,
Additionally, outfall #5 tested above the benchmark level for pH at 9.98 as outlined on page 6, Table 3
of the general permit. In accordance with this exceedance, Cree has instituted Tier. One actions to
include the following:
Tier One
If the first valid sampling results are above a benchmark value, or outside of the benchmark range, for
any parameter at any outfall:
Conduct a stormwater management inspection of the facility within two weeks of receiving
sampling results.

1. Conduct a stormwater management inspection of the facility within two weeks of receiving
sampling results.
2. Identify and evaluate possible causes of the benchmark value exceedance.
3. Identify potential and select the specific source controls, operational controls, or physical
improvements to reduce concentrations of the parameters of concern, and/or to bring
concentrations within the benchmark range.
4. Implement the selected actions within two months of the inspection.
5. Record each instance of a Tier One response in the SPPP. Include the date and value of the
benchmark exceedance, the inspection date, the personnel conducting the inspection, the
selected actions, and the date the selected actions were implemented.
DMR results from this recent testing for NCG030541 are included for review. Cree's next semi-annual
test period will occur July - December 2018 at which time pH will be re -analyzed for comparison to the
earlier benchmark exceedance.

January- June 2017, SDO's #1, #2, #3, #4, #5 DVJiR SE=GTIOili
To Whom It May Concern;
Please find enclosed the semi-annual stormwater Discharge Monitoring Reports (one original and one
copy) for a re -test of outfalls listed as NO DISCHARGE from Cree's earlier report on the five
stormwater outfalls located at Cree Wolfspeed, 3028 Cornwallis Road, Durham County, RTP NC.
Analytical reports were received from the laboratory on September 20, 2017, ESC Lab Sciences (NC ID
# ENV 375) conducted the analyses for the retest of all outfalls not sampled in the previous period for
the 1" 2017 semi-annual testing requirements.
No samples were collected at outfalls 42, #3, and #5 due to absence of flow during the retest event,
and are recorded as NO DISCHARGE on 9/12/2017. For the sampled outfalls, and as in previous
reports submitted to DEQ, levels for copper and zinc are above the benchmark values listed in Table 3
of section I1.13 of our stormwater permit for outfalls #001 and #004 (Cu) and outfalls 4001 and 4004
(Zn). In September 2014, Cree was granted an exemption from the requirement to continue following
Tier Two and Tier Three response actions as stated in Section B of the stormwater permit for these
parameters. Cree will continue to monitor these levels throughout the next semi-annual testing period
for 2017 and report any success in eliminating the elevated levels.
DMR results from this recent testing for NCG030541 are included for review.

Total Toxic Organics sampling is applicable only for those facilities which perform metal finishing operations, manufacture semiconductors, manufacture electronic crystals, or
manufacture cathode ray tubes. For purposes of this permit the definition of Total Toxic Organics is that definition contained in the EPA Effluent Guidelines for the facility subject
to the requirement to sample (for metal finishing use the definition as found in 40 CFR 433.11; for semiconductor manufacture use the definition as found in 40 CFR 469.12; for
electronic crystal manufacture use the definition as found in 40 CFR 469.22; and for cathode ray tube manufacture use the definition found in 40 CFR 469.31).
Facilities that incorporate a solvent management plan into the Stormwater Pollution Prevention Plan may so certify, and the requirement for TTO monitoring may be waived. The
solvent management plan shall include a list of the total toxic organic compounds used and the other elements listed in the General Permit. For those facilities electing to employ
the TTO monitoring waiver, the discharger shall sign the following certification statement:
"Based upon my inquiry of the person or persons directly responsible for managing compliance with the permit monitoring requirement for total toxic organics (TTO), I
certify that to the best of my knowledge and belief, no dumping of concentrated toxic organics into the stormwater or areas which are exposed to rainfall or stormwater
runoff has occurred since filing the last discharge monitoring report. I further certify that this facility is implementing the all the provisions of the solvent management
plan included in the Stormwater Pollution Prevention Plan."

CASE NARRATIVE ONE LAB. NATIONWIDE.
All sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times. All MDL (LOD) and RDL (LOQ)
values reported for environmental samples have been corrected for the dilution factor used in the E
analysis. All radiochemical sample results for solids are reported on a dry weight basis with the
exception of tritium, carbon-14 and radon, unless wet weight was requested by the client. All Method E
and Batch Quality Control are within established criteria except where addressed in this case narrative,
a non-conformance form or properly qualified within the sample results. By my digital signature below, I
affirm to the best of my knowledge, all problems/anomalies observed by the laboratory as having the
potential to affect the quality of the data have been identified by the laboratory, and no information or
data have been knowingly withheld that would affect the quality of the data. 0

GLOSSARY OF TERMS ONE LAB. NATIONWIDE.
Guide to Reading and Understanding Your Laboratory Report
The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not
intended as a comprehensive explanation, and if you have additional questions please contact your project representative,
Abbreviations and Definitions
MDL Method Detection Limit.
RDL Reported Detection Limit.
Rec. Recovery.
RPD Relative Percent Difference.
SDG Sample Delivery Group.
U Not detected at the Reportmg Limit (or MDL where applicable).
Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes
reported,
If the sample matrix contains an interfering material, or if concentrations of analytes in the sample are higher than the
Dilution
highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value
different than 1 is used in this field, the result reported has already been corrected for this factor.
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
Limits
for the method and analyte being reported. Successful OC Sample analysis will target all analytes recovered or
duplicated within these ranges.
Original Sample
The non -spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control
sample. The Original Sample may not be included within the reported SDG.
This column provides a letter and/or number designation that corresponds to additional information concerning the result
Qualifier
reported. If a Qualifier is present. a definition per Qualifier is provided within the Glossary and Definitions page and
potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
The actual analytical final result {corrected for any sample specific characteristics) reported for your sample. If there was
no measurable result returned for a specific analyze, the result in this column may state "ND' (Not Detected) or `BDL"
Result
(Below Detectable Levels). The information in the results column should always be accompanied by either an MDL
(Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect
or report for this analyze.
A brief discussion about the included sample results, including a discussion of any non -conformances to protocol
Case Narrative (Cn)
observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will
be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
This section of the report includes the results of the laboratory quality control analyses required by procedure or
Summary (Qc)
analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not
being performed on your samples typically, but on laboratory generated material.

General Stormwater Permit No. NCG0300001COC NO. NCG030541
January - June 2017, SDO #1, #2, #3, #4, and #5
To Whom It May Concern:
Please find enclosed the semi-annual stormwater Discharge Monitoring Reports (one original and one
copy) for the five stormwater outfalls located at Cree, Incorporated 3028 Cornwallis Drive, Durham,
Durham County, North Carolina.
During the collection event, no discharge from outfalls 1, 2,_3, 4, 5 was observed; therefore no analyses
were recorded for pH, copper, zinc, lead, oil and grease, and total suspended solids (TSS), and are
recorded as NO DISCHARGE in the results section of the DMR reporting form. Cree will obtain
further sampling at the next acceptable rain event for these outfalls and submit to DEQ at that
time.
Please contact me at 919-407-6101 if you need additional information.

Total Toxic Organics sampling is applicable only for those facilities which perform metal finishing operations, manufacture semiconductors, manufacture electronic crystals, or
manufacture cathode ray tubes. For purposes of this permit the definition of Total Toxic Organics is that definition contained in the EPA Effluent Guidelines for the facility subject
to the requirement to sample (for metal finishing use the definition as found in 40 CFR 433.1 1; for semiconductor manufacture use the definition as found in 40 CFR 469.12; for
electronic crystal manufacture use the definition as found in 40 CFR 469.22; and for cathode ray tube manufacture use the definition found in 40 CFR 469,31).
Facilities that incorporate a solvent management plan into the Stormwater Pollution Prevention Plan may so certify, and the requirement for TTO monitoring may be waived. The
solvent management plan shall include a list of the total toxic organic compounds used and the other elements listed in the General Permit. For those facilities electing to employ
the TTO monitoring waiver, the discharger shall sign the following certification statement:
"Based upon my inquiry of the person or persons directly responsible for managing compliance with the permit monitoring requirement for total toxic organics (TTO), 1
certify that to the best of my knowledge and belief, no dumping of concentrated toxic organics into the stormwater or areas which are exposed to rainfall or stormwater
runoff has occurred since filing the last discharge monitoring report. I further certify that this facility is implementing the all the provisions of the solvent management
plan included in the Stormwater Pollution Prevention Plan."

RE: Stormwater Discharge Outfall (SDO) Monitoring Report
Cree, Incorporated - Durham, Durham County, North Carolina
General Stormwater Permit No. NCG030000/C0C NO. NCG030541
July- December 2016, SDO #1, #2, #3, #4, and #5
To Whom It May Concern:
Please find enclosed the semi-annual stormwater Discharge Monitoring Reports (one original and one
copy) for the five stormwater outfalls located at Cree, Incorporated 3028 Cornwallis Drive, Durham,
Durham County, North Carolina. The analytical reports were received from the laboratory on December
23, 2016. ESC Lab Sciences (NC ID #ENV 375) conducted the analyses which completes the second
2016 semi-annual testing requirements for the Cornwallis Drive site.
As in previous reports submitted to DEQ, levels for copper and zinc are above the benchmark values
listed in Table 3 of section ILB of our stormwater permit for outfalls #001 and 4004 (Cu and Zn). In
September 2014, Cree was granted an exemption from the requirement to continue following Tier Two
and Tier Three response actions as stated in Section B of the stormwater permit for these parameters.
Cree will continue to monitor these levels throughout the next semi-annual testing period for 2017 and
report any success in eliminating the elevated levels.
In addition, value for TSS was above benchmark level at outfall 4004 during the sampling event; Cree
will therefore initiate Tier One activities as described in Section II, Part B, page 3 of General Permit
NCG030000, and will re-evaluate this parameter in our first semi-annual testing period in 2017.
DMR results from this recent testing for NCG030541 are included for review and completes Cree's
second semi-annual testing requirement for 2016 for the Cornwallis Drive site.
Please contact me at 919-407-6101 if you need additional information.

CASE NARRATIVE
ONE LAB, NATIONWIDE. 0
FP
All sample aliquots were received at the correct temperature, in the proper containers, with the
appropriate preservatives, and within method specified holding times. All MDL (LOD) and RDL (LOO)
values reported for environmental samples have been corrected for the dilution factor used in the F
analysis. All Method and Batch Ouaiity Control are within established criteria except where addressed
in this case narrative, a non-conformance form or properily qualified within the sample results. By my digital signature below, I affirm to the best of my knowledge, all problems/anomalies observed by the ❑ 3S
laboratory as having the potential to affect the quality of the data have been identified by the
laboratory, and no information or data have been knowingly withheld that would affect the quality of the
data.

' Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfali.
Z For sampling periods with no discharge at any single outfali, you must still submit this discharge monitoring report with a checkmark here.
3The total precipitation must be recorded using data from an on -site rain gauge. Unattended sites may be eligible for a waiver of the rain gauge requirement.
4 See General Permit, Table 3 identifying the especially sensitive receiving water classifications where the more protective benchmark applies.
5 Total Toxic Organics sampling is applicable only for those facilities which perform metal finishing operations, manufacture semiconductors, manufacture
electronic crystals, or manufacture cathode ray tubes. For purposes of this permit the definition of Total Toxic Organics is that definition contained in the EPA
Effluent Guidelines for the facility subject to the requirement to sample (for metal finishing use the definition as found in 40 CFR 433.11; for semiconductor
manufacture use the definition as found in 40 CFR 469.12; for electronic crystal manufacture use the definition as found in 40 CFR 469.22; and for cathode ray
tube manufacture use the definition found in 40 CFR 469.31).

Facilities that incorporate a solvent management plan into the Stormwater Pollution Prevention Plan may so certify, and the requirement for TCO monitoring
may be waived. The solvent management plan shall include a list of the total toxic organic compounds used and the other elements listed in the General
Permit. For those facilities electing to employ the TTO monitoring waiver, the discharger shall sign the following certification statement:
"Based upon my inquiry of the person or persons directly responsible for managing compliance with the permit monitoring requirement for total toxic organics
(TTO), I certify that to the best of my knowledge and belief, no dumping of concentrated toxic organics into the stormwater or areas which are exposed to rainfall or
stormwater runoff has occurred since filing the last discharge monitoring report. I further certify that this facility is implementing the all the provisions of the
solvent management plan included in the Stormwater Pollution Prevention Plan."

RE: Stormwater Discharge Outfall (SDO) Semiannual Monitoring Report
Cree, Incorporated - Durham, Durham County, North Carolina
General Stormwater Permit No. NCG030000/COC NO. NCG030541 (RTP/Wolfspeed)
January- June, 2016, SDO #1, #2, #3, #4, and #5
To Whom It May Concern:
Please find enclosed the semi-annual stormwater Discharge Monitoring Reports (one original and one
copy) for the five stormwater outfalls located at Cree's RTP/Wolfspeed site located at 3026 Cornwallis
Road, Durham, Durham County, North Carolina. The analytical reports were received from the
laboratory on July 14, 2016. Meritech Laboratories (Certificate 4165) conducted the analyses which
completes the 2016 first semi-annual testing requirements for the RTP/Wolfspeed site.
As in previous reports submitted to DEQ, levels for copper and zinc are above the benchmark values
listed in Table 3 of section II.B. of our permit for outfalls #'s 001,002,003,004 and 005 (Cu) and #'s
001,002,004,and 005 (Zn). As noted in previous reports, Cree has been granted an exemption from the
requirement to follow Tier Two and Tier Three response actions as stated in Section B of the stormwater
permit due to absence of these elements in our manufacturing processes. Cree will continue to monitor
these levels throughout the next semi-annual testing period for 2016 and report on any success in
eliminating the elevated levels.
Additionally, outfall #003 tested above the benchmark level for TSS (Total Suspended Solids) at 301
mg/l as outlined on page 6, Table 3 of the general permit. In accordance with this exceedance, Cree has
instituted Tier One actions to include the following:
Tier One
If the first valid sampling results are above a benchmark value, or outside of the benchmark
range, for any parameter at any outfall:
1. Conduct a stormwater management inspection of the facility within two weeks of receiving
sampling results.
2. Identify and evaluate possible causes of the benchmark value exceedance.

3. identify potential and select the specific source controls, operational controls, or physical
improvements to reduce concentrations of the parameters of concern, and/or to bring
concentrations within the benchmark range.
4. Implement the selected actions within two months of the inspection.
5. Record each instance of a Tier One response in the SPPP. Include the date and value of the
benchmark exceedance, the inspection date, the personnel conducting the inspection, the selected
actions, and the date the selected actions were implemented.
Cree's next semi-annual test period will occur July -December 2016 at which time TSS will be re-
analyzed for comparison to the earlier benchmark exceedance.
DMR results from this recent testing for NCG030541 are included for review and completes Cree's first
semi-annual testing requirement for 2016.
Please contact me at 919-407-6101 if you need additional information.

1 Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
Z For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark here.
3 The total precipitation must be recorded using data from an on -site rain gauge. Unattended sites may be eligible for a waiver of the rain gauge requirement.
4 See General Permit, Table 3 identifying the especially sensitive receiving water classifications where the more protective benchmark applies.
5 Total Toxic Organics sampling is applicable only for those facilities which perform metal finishing operations, manufacture semiconductors, manufacture
electronic crystals, or manufacture cathode ray tubes. For purposes of this permit the definition of Total Toxic Organics is that definition contained in the EPA
Effluent Guidelines for the facility subject to the requirement to sample (for metal finishing use the definition as found in 40 CFR 433.11; for semiconductor
manufacture use the definition as found in 40 CFR 469.12; for electronic crystal manufacture use the definition as found in 40 CFR 469.22; and for cathode ray
tube manufacture use the definition found in 40 CFR 469.31).

-Facilities that incorporate a solvent management plan into the Stormwater Pollution Prevention Plan may so certify, and the requirement for TTO monitoring
may be waived. The solvent management plan shall include a list of the total toxic organic compounds used and the other elements listed in the General
Permit. For those facilities electing to employ the TTO monitoring waiver, the discharger shall sign the following certification statement:
"Based upon my inquiry of the person or persons directly responsible for managing compliance with the permit monitoring requirement for total toxic organics
(TTO), I certify that to the best of my knowledge and belief, no dumping of concentrated toxic organics into the stormwater or areas which are exposed to rainfall or
stormwater runoff has occurred since filing the last discharge monitoring report. I further certify that this facility is implementing the all the provisions of the
solvent management plan included in the Stormwater Pollution Prevention Plan."

RE: Stormwater Discharge Outfall (SDO) Monthly Monitoring Report
Cree, incorporated - Durham, Durham County, North Carolina
General Stormwater Permit No. NCC0300001COC NO. NCG030433
January -June 2015, SDO #1, #2, #3A, #4A, #5, #6 and #7
To Whom It May Concern:
Please find enclosed the semi-annual Stormwater Discharge Monitoring Reports (one original and one
copy) for the seven stormwater outfails located at Cree, Incorporated, 4600 Silicon Drive, Durham,
Durham County, North Carolina. The analytical reports were received from the laboratory on July 8,
2015. Meritech Laboratories (Certificate #165) conducted the analyses which completes the first 2015
semi-annual testing requirements for the Durham site. Please note that outfall SDO-006 ("no access
during event") on the DMR sheet was not sampled at this time because the composite sampler in use
failed to produce a sample during the rain event.
As in subsequent reports submitted to DENR, levels for copper and zinc are above the benchmark
values listed in Table 3 of section II.B. of our stormwater permit for outfalls #001, 002, 004a, and 005
(Cu and Zn) and outfall #003a (Cu). In September 2014, Cree was granted an exemption from the
requirement to continue to follow the Tier Two and Tier Three response actions as stated in Section B
of the stormwater permit. Cree will continue to monitor these levels throughout the next semi-annual
testing period for 2015 and report any success in eliminating the elevated levels.
DMR results from this recent testing for NCG030541 are included for review and completes Cree's
first semi-annual testing requirement for 2015 for the Durham site.
Please contact me at 919-407-6101 if you need additional information.

Donna Lazzari

1 Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
z For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark here.
3The total precipitation must be recorded using data from an on -site rain gauge. Unattended sites may be eligible for a waiver of the rain gauge requirement.
° See General Permit, Table 3 identifying the especially sensitive receiving water classifications where the more protective benchmark applies.
5 Total Toxic Organics sampling is applicable only for those facilities which perform metal finishing operations, manufacture semiconductors, manufacture
electronic crystals, or manufacture cathode ray tubes. For purposes of this permit the definition of Total Toxic Organics is that definition contained in the EPA
Effluent Guidelines for the facility subject to the requirement to sample (for metal finishing use the definition as found in 40 CFR 433.11; for semiconductor
manufacture use the definition as found in 40 CFR 469.12; fa
tube manufacture use the definition found in 40 CFR 469.31)
Permit Date: 11/1/2012-10/31/2017
re use the definition as found in 40 CFR 469.22; and for cathode ray
SWO-245, last revised 10/25/2012
Page 1 of 3

Facilities that incorporate a solvent management plan into the Stormwater Pollution Prevention Plan may so certify, and the requirement for TTO monitoring
may be waived. The solvent management plan shall include a list of the total toxic organic compounds used and the other elements listed in the General
Permit. For those facilities electing to employ the TTO monitoring waiver, the discharger shall sign the following certification statement:
"Based upon my inquiry of the person or persons directly responsible for managing compliance with the permit monitoring requirement for total toxic organics
(TTO), I certify that to the best of my knowledge and belief, no dumping of concentrated toxic organics into the stormwater or areas which are exposed to rainfall or
stormwater runoff has occurred since filing the last discharge monitoring report. I further certify that this facility is implementing the all the provisions of the
solvent management plan included in the stormwater Pollution Prevention Plan."

Note: Results must be reported in numerical format. Do not report Below Detection Limit, BDL, <PQL, Non -detect, ND, or other similar non -numerical
format. When results are below the applicable limits, they must be reported in the format, "<XX mg/L" where XX is the numerical value of the detection
limit, reporting limit, etc. in mg/L.
Note: If you report a sample value in excess of the benchmark, you must implement Tier 1, Tier 2, or Tier 3 responses. See Genera! Permit text.

' Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfail.
2 For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark here.
3The total precipitation must be recorded using data from an on -site rain gauge. Unattended sites may be eligible for a waiver of the rain gauge requirement.
4 See General Permit, Table 3 identifying the especially sensitive receiving water classifications where the more protective benchmark applies.
5 Total Toxic Organics sampling is applicable only for those facilities which perform metal finishing operations, manufacture semiconductors, manufacture
electronic crystals, or manufacture cathode ray tubes. For purposes of this permit the definition of Total Toxic Organics is that definition contained in the EPA
Effluent Guidelines for the facility subject to the requirement to sample (for metal finishing use the definition as found in 40 CFR 433.11; for semiconductor
manufacture use the definition as found in 40 CFR 469.12; for electronic crystal manufacture use the definition as found in 40 CFR 469.22; and for cathode ray
tube manufacture use the definition found in 40 CFR 469.31).

Facilities that incorporate a solvent management plan into the Stormwater Pollution Prevention Plan may so certify, and the requirement for TTO monitoring
may be waived. The solvent management plan shall include a list of the total toxic organic compounds used and the other elements listed in the General
Permit. For those facilities electing to employ the TTO monitoring waiver, the discharger shall sign the following certification statement:
"Based upon my inquiry of the person or persons directly responsible for managing compliance with the permit monitoring requirement for total toxic organics
(TTO), I certify that to the best of my knowledge and belief, no dumping of concentrated toxic organics into the Stormwater or areas which are exposed to rainfall or
stormwater runoff has occurred since filing the last discharge monitoring report. I further certify that this facility is implementing the all the provisions of the
solvent management plan included in the Stormwater Pollution Prevention Plan."

RE: Stormwater Discharge Outfall (SDO) Monthly Monitoring Report
Cree, Incorporated - Durham, Durham County, North Carolina
General Stormwater Permit No. NCG0300001COC NO. NCG030541 (RTP)
January- June, 2015, SDO #1, #2, #3, #4, and #5
To Whom It May Concern:
Please rind enclosed the semi-annual Stormwater Discharge Monitoring Reports (one original and one
copy) for the five stormwater outfalls located at Cree's RTP site located at 3026 Cornwallis Road,
Durham, Durham County, North Carolina. The analytical reports were received from the laboratory on
July 8, 2015. Meritech Laboratories (Certificate 4165) conducted the analyses which completes the
2015 semi-annual testing requirements for the RTP site. Please note that outfall SDO-003 (no flow)
was not sampled at this time.
As in subsequent reports submitted to DENR, levels for copper and zinc are above the benchmark
values listed in Table 3 of section II.B. of our permit for outfalls #001,004 and 005 (Cu and Zn) and
4002 (Cu). Cree was granted an exemption from the requirement to continue to follow the Tier Two
and Tier Three response actions as stated in Section B of the stormwater permit. Cree will continue to
monitor these levels throughout the next semi-annual testing period for 2015 and report on any success
in eliminating the elevated levels
DMR results from this recent testing for NCG030541 are included for review and completes Cree's
first semi-annual testing requirement for 2015.
Please contact me at 919-407-6101 if you need additional information.

RE: Stormwater Discharge Outfall (SDO) Monthly Monitoring Report
Cree, Incorporated - Durham, Durham County, North Carolina
General Stormwater Permit No. NCG030000/COC NO. NCG030541 (RTP)
June- December 2014, SDO #1, 42, #3, #4, and #5
To Whom It May Concern:
Please find enclosed the semi-annual Stormwater Discharge Monitoring Reports (one original and one
copy) for the five stormwater outfalls located at Cree's RTP site located at 3026 Cornwallis Road,
Durham, Durham County, North Carolina. The analytical reports were received from the laboratory on
December 23, 2014. Meritech Laboratories (Certificate # 165) conducted the analyses which completes
the 2014 semi-annual testing requirements for the Durham site. Please note that outfall SDO-003 (no
flow) was not sampled at this time.
These results follow the actions implemented as 'Pier 2 response for elevated copper and zinc levels at
the facility. Notification that Cree, Inc. intended to implement the actions required as a Tier 2 response
was sent to the DWQ in January, 2014 based on the results of the stormwater sampling conducted in
December, 2013. Additional samples were obtained in February, 2014. As Cree has demonstrated
that no copper or zinc is used in its manufacturing process and has no clear source for the
contamination, DWQ has granted relief from further Tier response testing on September 24,
2014 (see attached). However, this letter indicates relief only for NCG030433 (Durham site) and
not for NCG030541 (RTP site) as was originally requested (attached request letter). Cree feels
this is an oversight and is requesting a second letter indicating Tier relief for the RTP site as
well.
DMR results from this recent testing for NCGO30541 are included for review and completes
Cree's semi-annual testing requirement for 2014.

Subsequent testing continues to report values for copper and zinc above the benchmark values listed in
Table 3 of section II.B. of our permit for outfalls #1,4 and 5(Cu and Zn), and within limits for all other
permit parameters. Cree will continue to monitor these levels throughout the semi-annual testing
periods for 2015 and report on any success to eliminate the elevated levels.
Please contact me at 919-407-6101 if you need additional information.

RE: Monitoring Request and Meeting Response August 1, 2014
Dear Mr. Parnell;
It was a pleasure meeting with you and Bethany Georgoulias Friday to discuss options for Cree's
stormwater monitoring for Cu and Zn. This letter is to follow up our meeting on Friday, August 1,
2014 at the DENR offices at 3800 Barrett Drive.
The meeting presented reasons why Cree's Durham and RTP (Research Triangle Park) facilities
should return to semi-annual stormwater monitoring from Tier 2 testing. Elevated copper and zinc
levels, we believe, are not originating from the Durham or RTP sites. We have conducted extensive
reviews of the sites for external sources of upper and zinc, and Cree does not use copper or zinc
compounds in the manufacturing processes which could contribute to these levels. Further, Cree has
questioned the proximity of a copper smelting plant in the vicinity that could be contributing to these
elevated copper and zinc levels to be considered by DENR as a source due to atmospheric conditions.
It was also noted that pH data from the May 2014 sampling event was below 6.0 for all 12 outfalls
analyzed by Meritech, Inc., but normal for Enco Laboratories for 10 out of the 12 outfalls. Cree
considers this to be inconsistent with sampling from June 2013 thru February 2014 where all pH values
were within normal range. The discrepancy is probably due to analysis error than to real values.
Based on these findings, Cree formally asks to resume semi-annual stormwater testing for the fall
reporting period.
Please contact me at 919-407-6101 if you need additional information.

June- December 2013, SDO #I, 42, #3A, #4A, #5, #6 and #7
To Whom It May Concern:
Please find enclosed the monthly Stormwater Discharge Monitoring Reports (one original and one
copy) for the seven stormwater outfalls located at Cree, Incorporated, 4600 Silicon Drive, Durham,
Durham County, North Carolina. The analytical reports were received from the laboratory on .tune 9,
2014. Meritech Laboratories (Certificate 9165) conducted the analyses.
These results are following the actions that have been implemented as a Tier 2 response for elevated
copper and zinc levels at the facility. Notification that Cree, Inc. intended to implement the actions
required as a Tier 2 response was sent to the DWQ in January, 2014 with the results of the stormwater
sampling conducted in December, 2013. Additional samples were obtained in February, 20I4 and
again for this report in May, 2014.
The Cree Durham site received an annual spw3 inspection by David Parnell on April S, 2014.
Suggestions from that inspection have been implemented , and additional actions have been taken to
identify and limit the amount ofcopper and zinc in the storm water. However, subsequent testing
continues to report values for copper and zinc above the benchmark values listed in Table 3 of section
II.I3. of our permit for all outfall discharge monitoring points with the exception of outfalls #6 and #7
for zinc.
As test results continue at elevated levels for copper and zinc for four successive sampling periods,
Cree is requesting a meeting with DWQ to determine the best path forward to address these elevated
values.

Please contact me at 919-407-6101 if you need additional information.

Facilities that incorporate a solvent management plan into the Stormwater Pollution Prevention Plan may so certify, and the requirement for TTO monitoring
may be waived. The solvent management plan shall include a list of the total toxic organic compounds used and the other elements listed in the General
Permit. For those facilities electing to employ the TTO monitoring waiver, the discharger shall sign the following certification statement:
"Based upon my inquiry of the person or persons directly responsible for managing compliance with the permit monitoring requirement for total toxic organics
(TTO), l certify that to the best of my knowledge and belief, no dumping of concentrated toxic organics into the stormwater or areas which are exposed to rainfall or
stormwater runoff has occurred since filing the last discharge monitoring report. I further certify that this facility is implementing the all the provisions of the
solvent management plan included in the Stormwater Pollution Prevention Plan."

1 Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
2 For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark here.
3The total precipitation must be recorded using data from an on -site rain gauge. Unattended sites may be eligible for a waiver of the rain gauge requirement.
4 See General Permit, Table 3 identifying the especially sensitive receiving water classifications where the more protective benchmark applies.
5 Total Toxic Organics sampling is applicable only for those facilities which perform metal finishing operations, manufacture semiconductors, manufacture
electronic crystals, or manufacture cathode ray tubes. For purposes of this permit the definition of Total Toxic Organics is that definition contained in the EPA
Effluent Guidelines for the facility subject to the requirement to sample (for metal finishing use the definition as found in 40 CFR 433.11; for semiconductor
manufacture use the definition as found in 40 CFR 469,12; for electronic crystal manufacture use the definition as found in 40 CFR 469.22; and for cathode ray
tube manufacture use the definition found in 40 CFR 469.31).
