I. DIRECTIONS TO SITE: From FRO take Green St. for 0.17 mile to the roundabout and turn onto
Gillespie St. Continue for 0.16 mile and turn right onto Russell St.and continue 0.54 mile and turn left onto
Robeson St. Continue for 2.4 miles and turn left onto US401. Continue for 24.1 miles then turn right onto
Wire Rd. and continue for 11.45 miles then turn right onto US 74 West.Follow US 74 West for 30 miles
into Anson County. After crossing the bridge,turn right onto the first road,Power Plant Road(SRI748).
The plant is approximately 3 miles away,at the end of Power Plant Road. Push the gate call button to
speak. The admin office is the first bldg on the left. When leaving the admin building back away from the
gate until it opens. Then you can drive through and leave. IMPORTANT: Call the facility contact a
couple of days before you plan on inspecting. The facility can be remotely operated,so it is typically
unmanned and inspections should be pre-planned.
II. SAFETY: Standard FRO safety gear.Double hearing protection is required when the combustion turbines
are operating; ear muffs can be provided by the facility.
III. FACILITY DESCRIPTION: Duke Energy Progress—Blewett is an electricity generation plant which
operates six 4 MW hydroelectric units,and four 18 MW,No. 2 fuel oil fired Combustion Turbines(CT).
The CTs are only operated as fast-start(6 minutes)peaking units or during maintenance or repair of the
hydroelectric units, or to cover gaps in service if other units in the region drop offline for any reason. This
situation normally only occurs during the colder months. The turbines do not utilize water injection,nor is
the air entering the combustion chamber pre-cooled, so turbine efficiency is greatly influenced by ambient
air temperatures.

V. INSPECTION SUMMARY: On 29 October 2020,I Mike Thomas,of FRO DAQ, conducted a
compliance inspection of Duke Energy Progress—Blewett in Lilesville,Anson County. I met with Kim
Kashmer, Lead EHS Professional for an announced inspection of the facility. Ms.Kashmir verified the
FacFinder is up to date and accurate. She also provided the required records,which were very well
organized.
I reviewed the facility's records for fuel oil analysis, inspections and maintenance,and NOx emissions. All
appeared to be complete and up to date. I inquired if the facility was still burning the debris collected off of
the dam periodically. Ms.Kashmer stated that the facility still intended to burn the material periodically but
that they have not burned since November of 2018. She went on to say that it was still their practice to
insure that only vegetative material is burned and that all trash is removed prior to burning.
Ms.Kashmer led me on a tour of the facility,which was not operating during the inspection. Ms.Kashmer
described the facility operations and pointed out the emergency generator that controls the microwave
tower in the event of a power outage. No issues were observed with the generator. I also observed the area
designated for right of way maintenance by the operators of the hydro plant. The material collected
appeared to be mostly large logs and tree limbs. It did not appear to contain any non-vegetative material.

The Permittee shall submit an application for permit renewal, including an emission inventory for CY
2015,no later than 90-days prior to permit expiration.
APPEARED IN COMPLL4NCE: The facility submitted the most recent permit renewal application
and emissions inventory on time. The permit will expire on 31 December 2024. The renewal
application will be due no later than 02 October 2024, and must include an emission inventory for CY
2023.
B. 15A NCAC 2D .0516—SULFUR DIOXIDE EMISSIONS FROM COMBUSTION SOURCES—
S02 emissions from the CTs shall not exceed 2.3 lb/mmBtu.
APPEARED IN COMPLL4NCE: The facility is permitted to combust No. 2 fuel oil up to 0.5 wt.%
su fur, which has an AP-42 emission factor of 0.51 lb S01/mmBtu. The facility only accepts ultra-low
suer diesel(ULSD), as verified by fuel certifications. The facility also takes fuel samples annually,
and the last sample indicated a sulfur content of 0.0073 wt. %.
C. 15A NCAC 2D .0521—VISIBLE EMISSIONS CONTROL REQUIREMENT—Visible emissions
from each emission source manufactured after 1 July 1971, shall not exceed 20% opacity when
