Subject: Pretreatment Review of Industrial Waste Survey (IWS)
Program: City of Eden
WWTP: Mebane Bridge WWTP- NPDES Number NCO025071
Rockingham County
Dear Chris Powell:
The Municipal Unit of the Division of Water Resources has reviewed the Industrial Waste Survey (IWS) for the
City of Eden. The IWS was received by the Division on September 21, 2020. Additional information was
requested by the Division and the revised IWS was submitted on November 23, 2020. Clarifications were
requested and the review concluded on December 16, 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 47 commercial establishments/industries. Five industries were not in business. Ten
industries contribute only domestic flow, and 32 Industries contribute approximately 648,024 gpd (0.65 MGD) of
process flow/non-domestic flow, 4.8 % of the City's WWTP permitted flow, 13.5 MGD. The permitted SIU flow
is 1.3 MGD. The City has 3 Significant Industrial Users (SIUs) and 2 industries with a local permit.
Please remember it is the responsibility of the POTW to continue efforts to ensure that any SIU, as defined by
NCAC 15A 211 .0903(b)(30) (A) through (D), are identified and subsequently added to the City's pretreatment
program. This includes evaluation of new industrial users (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: Your next updated IWS is due on December 17, 2025 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).
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.
