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
July -December 2019, WOLF #1, #2, #3, #4, and #5

To Whom It May Concern:
Please find enclosed the semi-annual stormwater Discharge Monitoring Reports for the five stormwater
outfalls located at Cree, Inc., 3028 Cornwallis Road, Durham, North Carolina. The analytical report was
received from the laboratory on November 27, 2019. Pace Analytical Services (NC Certification #40,
633, 67) conducted the analyses which completes the second 2019 semi-annual testing requirements
for the Cornwallis Road site.
Discharge samples were collected at outfalls: #1, #2, and #4. Outfall #3 and #5 had NO
DISCHARGE. 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 II.B of our stormwater permit for
outfalls #1 and #4 (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 the
spring sampling event have returned to the appropriate range.
i, 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.
' 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.
s 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."

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 me/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 General Permit text.
Part B: Vehicle Maintenance Area Monitoring Results: only for facilities averaging > 55 gal of new oil per month.
