DANIEL SMITH Director Town of Ramseur Attn: Terry Lewallen, Wastewater Operator in Responsible Charge 724 Liberty Street, PO Box 545 Ramseur, NC 27316 Transmitted via email to t.lewallen@townoframseur.org NORTH CAROLINA Environmental Quality 8/4/2021 Subject: Pretreatment Review of Industrial User Permit Renewal Program: Town of Ramseur WWTP: Town of Ramseur - NPDES No NC0026565, 0.48 MGD Randolph County Dear Terry Lewallen: The Municipal Unit of the Division of Water Resources has reviewed the Industrial User Permit (IUP) renewal submitted by the Town of Ramseur for the following Significant Industrial User (SIU). IUP # SIU NAME - CFR 0002 MATLAB, Inc. - 433 The IUP renewal was received by the Division on July 29, 2021. The review indicates that the IUP is adequate and meets the minimum requirements of 15A NCAC 2H .0905 - .0916 and 40 CFR 403.8(f)(1)(iii). The IUP was modified to match current model IUP, treatment units list and schematic were updated, and lowered the detection level for silver from 0.003 mg/L to 0.002 mg/L, among other changes. Regardless of this approval action today, within 180 days of the effective date of any reissued/modified NPDES permit, the Permittee would be required to submit to the Division a written technical evaluation of the need to revise local limits (i.e., an updated IWS, or documentation of why one is not needed). This action may include revising, updating, or adding to the list of SIUs regardless of timeframe. Federal and State pretreatment regulations require the local delegated pretreatment program to effectively control and document the wastewater discharge from SIUs to the POTW. It is the POTW's responsibility to ensure that these objectives are consistently met. Thank you for your continued support of the Pretreatment Program. If you have any questions or comments, please contact Diana at [diana.yitbarek@ncdenr.gov], the Pretreatment Coordinator Keyes at [keyes.mcgee@ncdenr.gov], or the Unit Supervisor, Michael at[michael.montebello@ncdenr.gov].
