' 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.

RE: Stormwater Discharge Outfall (SDO) Monitoring Report
Cree, Inc., 4600 Silicon Drive, Durham, Durham County, North Carolina
General Stormwater Permit No. NCG030000/COC NO. NCG030433
July - December 2019, SDO #1, #2, #3, #3A, #4, #5, #6 and #7
To Whom It May Concern:
Please find enclosed the semi-annual stormwater Discharge Monitoring Report for the eight stormwater
outfalls located at Cree, Inc., 4600 Silicon Drive, Durham, Durham County, North Carolina. The
analytical reports were 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 Silicon Drive site.
Discharge samples were collected at outfall #1, #2, #5, #6 and V. No sample was collected at
outfall #4, #3, or #3A due to absence of flow, and is recorded as 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 11.13 of our stormwater permit for outfalls #3, #5, #7 (Cu)
and outfalls #2 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. As such, outfalls #1 (Cu), #2 (Cu) and #6 (Cu & Zn) have
returned to levels below their benchmarks, since their exceedance in the spring sampling event. In
addition, outfalls #5 and #6 are now within pH benchmark range, after the spring sampling exceedance
and resulting investigation.
