Subject: Pretreatment Review of Industrial Waste Survey (IWS)
Program: Mebane WWTP: City of Mebane - NPDES Number NC0021474, 2.5 MGD
Alamance County
Dear Amy Varinoski
The Municipal Unit of the Division of Water Resources has reviewed the IWS for the City of Mebane. This IWS
was received by the Division on November 23, 2020. Proper completion of an IWS is required by your NPDES
permit. The review indicates that the IWS is adequate and meets the minimum requirements of 40 CFR 403.8 (f)
(2)-
The City's IWS included 44 commercial establishments/industries that contribute 0.21 MGD of non -domestic
flow. The City has 5 Significant Industrial Users (SIUs), 4 industries with local permits, and 2 industries with
zero discharge permits.
Please remember it is the responsibility of the POTW to continue efforts to ensure that any SIU, as defined by
NCAC 15A 214.0903(b)(30) (A) through (D), are identified and subsequently added to the Mebane 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: January 10, 2026, unless conditions at the POTW change significantly and thus warrant an
earlier submittal. Furthermore, 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. Pursuant to 15A NCAC 02H .0907(b) either the Division or the permittee may initiate pretreatment program
revisions. Any additional conditions or requirements provided to the permittee related to pretreatment or
pretreatment program updates must be complied with separately from this approval action.
If you have any questions or comments, please contact Diana Yitbarek at 919 707 9130 [email:
diana.yitbarek&ncdenr. og_v]. Thank you for your continued cooperation with the Pretreatment Program.
Sincerely,
