Subject: Review of Industrial Waste Survey (IWS)
Program: City of Burlington
South WWTP and East WWTP - NPDES No NC0023876 & NC0023868
Alamance County
Dear Permittee,
The Municipal Unit of the Division of Water Resources has reviewed the Industrial Waste Survey (IWS) for the
City of Burlington. The IWS was initially received by the Division on July 1, 2021, followed by more information
and revisions received on July 22, 2022. The City's NPDES permits require proper completion of an IWS. The
review indicates that the IWS is adequate and meets the requirements of 40 CFR 403.8 (f) (2). Please ensure to
replace or update POTW's IWS with the approved one.
The City's IWS included 185 industrial, commercial, and institutional (ICI) users and currently has 12 Significant
Industrial Users (SIUs).
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 City's pretreatment
program. This includes evaluating new IUs before they commence discharge and evaluating existing IUs determined
to be not SIUs that make changes to their process.
Next IWS Due Date: August 9, 2027, unless conditions at the POTW or industrial users 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 (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. Pursuant to 15A NCAC 02H .0907(b), either the Division or the
Permittee may initiate pretreatment program revisions.
Thank you for your continued cooperation with the Pretreatment Program. If you have any questions or comments,
please contact Keyes McGee at [e-mail], or the Unit Supervisor, Michael Montebello, at
michael.montebello @ncdenr. goy.
Sincerely,
