Dear Renee Smith:
1/26/2021
The Municipal Unit of the Division of Water Resources has reviewed the IWS for the Contentnea MSD. This
IWS was received by the Division on September 29,2020. 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 Contentnea MSD's IWS included 23 commercial establishments/industries from the towns of Ayden,
Grifton, and Winterville. The City has 3 Significant Industrial Users (SIUs) that contribute about 0.05 MGD.
Please remember it is the responsibility of the POTW to continue efforts to ensure that any SIU, as defined by
NCAC 15A 2H .0903(b)(30) (A) through (D), are identified and subsequently added to the Contentnea MSD
pretreatment program. This includes evaluation of new IUs before they commence discharge and evaluation of
existing IUs determined to be not SIUs that make changes to their process.
Next IWS Due Date: January 26, 2026 unless conditions at the POTW change significantly and thus warrant an
earlier submittal. 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 Significant Industrial Users (SIU's) regardless
of timeframe. 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.
Thank you for your continued cooperation with the Pretreatment Program. If you have any questions or
comments, please contact Diana Yitbarek at 919 707-9130/[e-mail], or the Unit Supervisor,
Michael Montebello, at 919 707-3624/[e-mail].
Sincerely,
