information received June 11, 2021, we are forwarding herewith Permit No. WQ0038580 dated September
1, 2021, to the Town of Hillsborough for the continued operation of the subject residuals management
program.
This permit shall be effective from the date of issuance through January 31, 2028, shall void Permit
No. WQ0038580 issued August 19, 2016, and shall be subject to the conditions and limitations as specified
therein. The Permittee shall submit a renewal application no later than August 4, 2027.
Please pay particular attention to the monitoring requirements listed in Attachment A for they may
differ from the previous permit issuance. Failure to establish an adequate system for collecting and
maintaining the required operational information shall result in future compliance problems.
Please note that on September 1, 2018, North Carolina Administrative Code Title 15A Subchapter
02T Waste not Discharged to Surface Waters was readopted. Accordingly, this permit incorporates the
requirements of these rules, therefore, please take the time to review this permit thoroughly.
The Division has removed the following permit conditions since the last permit issuance dated
August 19, 2016:
Old Condition III.7. This condition has been replaced by New Condition III.9.
Old Condition III.8.h. This condition requirement has been removed.
Old Condition III.9. This condition has been replaced by New Condition III.9.
Old Condition III.10. This condition has been replaced by New Condition III.9.

Class A biological residuals; per the designation of residual sources in Attachment A for this
permit, the generated residuals are non-biological.
Condition III.6. This condition lists the requirements for staging and storing biological and
non-biological residuals to be land applied so that leachate runoff is prevented.
Condition III.8.l. This condition prohibits land application of Class A residuals within
watersheds classified as WS-1 and critical areas of WS-II though WS-IV.
Condition III.9. This condition requires all third-party entities involved in the land application
of bulk Class A residuals meet the requirements of 15A NCAC 02T .1108(b) and 02T
.1109(a)(1).
Condition VI.3. This condition states that there are no variances to administrative codes or
general statutes governing the construction or operation of the facilities permitted herein, unless
