Do not click links or open attachments unless you verify. Send all suspicious email as an attachment to report.spam@nc.gov Mrs. Georgoulias, Thank you for the electronic copies of the draft permit. Please find below my comments in regards to the addition of "internal" or upstream sampling locations. Part II, Section D, A (2.)(1) REQUIREMENT TO EVALUATE SAMPLING POINTS FOR STORMWATER PRIOR TO WASTEWATER COMMINGLING AND MONITOR FOR PARAMETERS The permittee shall: (1) identify at least three potential "internal" sampling points at the plant site where stormwater sampling prior to commingling with cooling water discharge could be feasible; Comments: There is no guidance from EPA (EPA-B-09-003 Industrial Stormwater and Sampling Guide, 2009) for sampling "internal" or upstream locations. The EPA Guidance states that "Stormwater samples are collected from a site's discharge points (or outfalls) for laboratory analysis and the results are compared with benchmark pollutant concentrations as an indicator of the performance of stormwater control measures". Rainfall in the facility is generally sheet flow into drains with either round or rectangular metal grating covers. These drainage catchments are designed with a discharge pipe elbowed down and submerged. Any floating material is kept from being discharged. Any solid material falls to the bottom of the catchment. These drain catchments are inspected and cleaned periodically as per the Stormwater Pollution Prevention Plan (SWPPP). Sampling these locations would require removal of the drain covers, which are constructed of heavy steel grating and require forklifts and chains. Due to safety concerns, It is not feasible to conduct this activity during a storm event. Furthermore, attempting to collect a sample in a catchment basin may result in samples that are not representative of water that is actually discharged off -site due to turbulence in the basin created by runoff as well as from taking the sample itself. Please contact me if you have any questions.

(copied on this e-mail) Charlie Conner needs to be removed for billing. You can bill to Dean and he will get it processed with accounting. Jeff Woodruff is still here and is our Lab Manager, Billy Thompson is no longer with the company. The address is the same and it should be to Dean's attention. BR, Mark From: Georgoulias, Bethany<bethany.georgoulias@ncdenr.gov> Sent: Friday, February 1, 2019 10:01 AM To: Lundblad, Mark <Mark.Lundblad@sglcarbon.com> Subject: SGL Carbon - NPDES Stormwater Permit Mr. Lundblad: I am working on the draft renewal stormwater permit for SGL Carbon, and I know there's been a lot of turnover of staff in the last few years since we received the original application. I wanted to get updated contacts for this permit so that we can send the draft to the right place when it's ready and make sure our database is current. I was on site with Linda Wiggs of DWR and Isaiah Reed of DEMLR last spring, and I think we met with Jeff Woodruff and Billy Thompson, maybe (?) Could you please review the attached summary report and let me know contact information that should be updated? Please be sure to include phone numbers and email addresses, and let me know who the best Permit Contact is for future questions. Also, we owe you all an acknowledgement letter for the renewal application received back in 2013, and I want to verify the address to which I should send that. Would it be to your attention at the Jamestown Road address? Best regards, Bethany Georgoulias Environmental Engineer Stormwater Program, Division of Energy, Mineral, and Land Resources N.C.
