REGAN Secretory Water Resources LINDA CULPEPPER Environmental Quality Interim Director July 2, 2018 Danny Gabriel, Mayor Town of Cleveland P.O. Box 429 Cleveland, NC 27013 Subject: Pretreatment Review of Industrial User Pretreatment Permit Renewal Program:Town of Cleveland NPDES Permit No: NC0049867 Rowan County Dear Mr. Gabriel: The Pretreatment, Emergency Response, and Collection Systems (PERCS) Unit of the Division of Water Resources has reviewed the Industrial User Pretreatment Permit(IUP) renewal submitted by the Town of Cleveland for the following Significant Industrial User(SIU). The IUP renewal was initially received by the Division on June 12, 2018,followed by revisions received on June 29, 2018. IUP SIU 0001 Daimler Trucks North America, LLC The review, with the observation below, indicates that the IUP is adequate and the minimum requirements of 15A NCAC 2H .0905 and .0916 and 40 CFR 403.8(f) (1) (iii) are met. 1. Copper Over Allocation: It appears that current Allocation Table is over allocated with new copper IUP limit (see attached updated AT). Please review the limit with recent industry sampling data and resolve over allocation next time the HWA is submitted which is due by October 1, 2018. Federal and State pretreatment regulations require the local delegated pretreatment program to effectively control and document the discharge of wastewater from Significant/Categorical Industrial Users to the POTW. It is the POTW's responsibility to ensure that these objectives are consistently met. Thank you for your continued cooperation with the Pretreatment Program. If you have any questions or comments, please contact Monti Hassan at (919) 807-6314 [email: Monti.Hassan@ncdenr.gov] or Deborah Gore, Unit Supervisor at(919) 807-6383 [email: Deborah.Gore@ncdenr.gov]. incerely, 1�Q�jr Monti Hass n Division of Water Resources MH/cleveland.iup.ren.016 cc: Wes Bell,Mooresville Regional Office Central Files PERCS Unit Notl�ir,g Compares -..
