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). • Permit Date:11/1/2012-10/31/2017 SWU-245, last revised 10/25/2012 y 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." acme Print name) Title(Print title) 7i/o (Sig re) (Date) Note: Results must be reported in numerical format.

The analytical reports were received from the laboratory on July 14, 2016. Meritech Laboratories (Certificate#165) 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 TS S (Total Suspended Solids) at 301 mg/1 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.
