PUBLIC NOTICE
N.C. DEPARTMENT OF ENVIRON-
MENTAL QUALITY INTENT TO
ISSUE: NPDES
WASTEWATER PERMIT
#NC0004774 AND STORMWATER
PERMITS #NCS000554 AND
#NCS000578
The N.C. Department of Environ-
mental Quality (DEQ) proposes to
issue National Pollutant Discharge
Elimination System (NPDES) per-
mits to Duke Energy Carolinas,
LLC, effective 90 days from the
publish date of this notice. DEQ
is inviting public comment on the
draft permits and has also sched-
uled a public hearing to gather
comments. All comments received
in writing by June 20, 2018 or pre-
sented at the public hearing will be
considered in the agency's final
determination regarding permit is-
suance and permit provisions.
PERMIT APPLICATIONS
Duke Energy Carolinas LLC, P.O.
Box 1006, Charlotte, N.C., has
applied for NPDES permits to
discharge wastewater and storm -
water from the Buck Combined
Cycle Station, Dukeville Road,
Rowan County, N.C., which com-
prises the Buck Steam Station
and Buck Combustion Turbine
Combined Cycle (CTCC) Station.
The facilities discharge to the
Yadkin River (High Rock Lake) in
the Yadkin -Pee Dee River Basin.
Chlorides, total dissolved solids,
and certain metals in one or more
discharges are water quality -limit-
ed. These discharges may affect
future allocations in this portion of
the receiving stream.
The thermal component of the
wastewater discharge is subject
to effluent limitations under the
federal Clean Water Act sec-
tions 301/306 and 15A NCAC
2B.0211(3)(j), which prohibits an
exceedance of 2.8 degrees C
(5.04 degrees F) above the nat-
ural water temperature, and in no
case to exceed 35 degrees C (95
degrees F). The permit holder has
requested a continuance of a CWA
316(a) variance, which would im-
pose less stringent temperature
limitations on the discharge. The
proposed variance imposes a
monthly average limit of 35 de-
grees C (95 degrees F). On the
basis of 15A NCAC 2B.0208(2)
(b) and other lawful standards
and regulations, DEQ proposes to
continue the 316(a) variance with
renewal of the permit.
The draft wastewater permit and
related documents are available
online at: haps://bit.ly/2KSG7rm.
The draft stormwater permit and
related documents are available
online at: https:Hbit.ly/2191 G58.
Printed copies of the draft permits
and related documents may also
be reviewed at the department's
Mooresville Regional Office. To
make an appointment to review
the documents, please call 704-
663-1699.

mental Quality will hold a public
