Dear Mr.Neuschafer:
The Division of Water Resources (hereby known as the Division) has determined that the City of
Dunn Wastewater Treatment Plant (WWTP) is unable to adequately treat the volume of wastewater
flow it receives on a daily basis. This determination has been reached based upon 1) an analysis of
data provided by the facility on its monthly self-monitoring reports; and 2) the reporting of sanitary
sewer overflows(SSOs) and the associated 5-day report submitted to the Division.
A review of self-monitoring and reporting data submitted to the Division since April 2017 has
indicated the occurrence of six(6)violations of the NPDES permit effluent limit for flow and twenty-
two (22) SSOs.

North Carolina General Statute §145-215.67(a) states, in part,that no person subject to the provision
of NCGS 143-215.1, 143-215.108, or 143-214.109 shall cause or allow the discharge of any wastes
to a waste-disposal system in excess of the capacity of the disposal system or of anywastes which
p Y P h' P Y
the waste-disposal system cannot adequately treat. Should these terms be violated,NCGS 143-215.67
states a moratorium can be imposed "on the addition of waste to a treatment works" if the treatment
works is not capable of adequately treating additional waste.
Based upon the facts and determination noted above, the City of Dunn WWTP is hereby placed on a
moratorium prohibiting the introduction of any additional waste to the collection system tributary to
the WWTP. This is to be interpreted as to prohibit the issuance of permits for new sewer lines to be
connected to the WWTP, any new tap-ons to the existing collection system, the introduction of
significant volumes of new wastewater flow via existingtaps(subject to theprovisions of the statute),
p
and/or the acceptance of new flows at the WWTP (such as a septage receiving station). This
moratorium shall become effective 45 days from your receipt of this letter.
This moratorium will remain in effect until the City of Dunn has sufficiently demonstrated it can
transport the wastewater via the collection system and subsequently treat the wastewater flowing to
the City of Dunn WWTP and has obtained written notification from the Division of the lifting of this
moratorium.
As required by NCGS 143-215.67(d), the City of Dunn shall give public notice that a moratorium
will be placed on the discharge of additional waste to the City of Dunn WWTP within 15 days of the
receipt of this letter. The City of Dunn shall give public notice of the moratorium by publication of
the notice one time in a newspaper having general circulation in Harnett County. The notice shall be
as provided in the attached, sample public notice.
The City of Dunn shall provide an affidavit of publication and a copy of the public notice to the
Division within 30 days of publication of the public notice.

of North Carolina General Statutes. Failure to place the public notice may subject the City of Dunn
to additional enforcement action by this office.
