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 — July 2019, 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, North
Carolina. The analytical reports were received from the laboratory on November 23, 2018. ESC Lab
Sciences (NC ID #ENV 375) conducted the analyses which completes the second 2018 semi-annual
testing requirements for the Cornwallis Road site.
Discharge samples were collected at outfalls: #1, #2, #4, and #5. Outfall #3 had NO
DISCHARGE. For the sampled outfalls, and as in previous reports submitted to DEC, levels for copper
and zinc are above the benchmark values listed in Table 3 of section ILB of our stormwater permit for
outfalls #1, #4, and #5 (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 and report any success in eliminating the elevated levels.
In addition, the values for pH reported below benchmark levels at outfalls #1, #2, and #5 during this
event. A Tier I response followed this data. Stormwater was retested for pH on July 4, 2019 and all
outfalls were within the benchmark range.
DMR results from this recent testing for NCG030541 are included for review. Please contact me at
919-407-6101 if you need additional information.

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.
'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.
See General Permit, Section B, Table 1 to identify 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."

QUALIFIERS
Project: Stormwater RTP 6-20-19
Pace Project No.: 92434026
DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
NO - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL- Adjusted Method Detection Limit.
Pace Analytical services, LLC
6701 Conference Drive
Raleigh, NC 27607
[phone]
PQL - Practical Quantitation Limit.
RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
CUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean -Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyle is a combined concentration.
ANALYTE QUALIFIERS
R1 RPD value was outside control limits.
