Subject: Pretreatment Review of Industrial Waste Survey (IWS)
Program: MSD Buncombe, NPDES Permit No: NCO024911
Buncombe County
Dear Mr. Ledford:
The Pretreatment, Emergency Response, and Collection Systems (PERCS) Unit of the Division of Water
Resources has reviewed the Industrial Waste Survey (IWS) for MSD Buncombe. This IWS was received by the
Division on November 12, 2019. Additional information was requested and was received on March 25, 2020.
The review indicates that the IWS is adequate and meets the minimum requirements of 40 CFR 403.8 (f) (2).
Proper completion of an Industrial Waste Survey is required by your NPDES permit.
Please remember it is the responsibility of the POTW to continue efforts to ensure that any Significant Industrial
Users (SlUs), as defined by NCAC 15A 2H .0903(b)(30) (A) through (D), are identified and subsequently added
to the District's pretreatment program. This includes evaluation of new IUs before they commence discharge and
evaluation of existing Ns determined to be not SIUs that make changes to their process.
Next IWS Due Date: Your next updated IWS is due on November 1, 2024 unless conditions at the POTW change
significantly and thus warrant an earlier submittal.
If you have any questions or comments, please contact Vivien Zhong at [phone] [email:
[e-mail]]. Thank you for your continued cooperation with the Pretreatment Program.
Sincerely,
EUDocuSigned by:
