1. DIRECTIONS TO SITE: In Laurinburg,take 74 West through Rockingham, and into Anson County.
After crossing the Pee Dee River,turn right onto the first road,Power Plant Road. The plant is
approximately 3 miles away, at the end of Power Plant Road. Press the button at the gate callbox in order
to gain entry. The admin building is the first building on the left. 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.
11. SAFETY: Standard FRO safety gear. Double hearing protection is required when the combustion
turbines are operating; ear muffs can be provided by the facility.
111. 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 31 July 2019,Mike Thomas and I,Evangelyn Lowery-Jacobs of FRO
DAQ, conducted a compliance inspection of Duke Energy Progress—Blewett in Lilesville, Anson
County. e met with Kim K.ashmer,Lead EHS Professional, and.Joe Rivers, Combustion Turbine
Operator for an announced inspection of the facility. Ms. Kashmir verified the Faff finder is up to date
and accurate. Mr. Rivers provided the required records,which were very well organized.
We reviewed the facility's records for fuel oil analysis, inspections and maintenance, and NOx emissions.
All appeared to be complete and up to date. We asked how often the facility conducts right of way
maintenance at the hydro plant. Mr. Rivers stated that the facility collects logs and other vegetative
debris from the inlet screens at the hydro plant, and burns the material once or twice per year. It usually
takes one full day to burn the material,but sometimes if the wood is not dry enough it can take two.
Ms.Kashmer and Mr. Rivers led us on a tour of the facility, which was not operating during the
inspection. Mr.Rivers 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. We 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.

A. 15A NCAC 2 . 2 2—PERMIT RENEWAL AND EMISSION INVENTORY REQIREMENT
—The Permlttee 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 C .L NC"E. 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 COMBUSTIONC S—
S02 emissions from the CTs shall not exceed 2.3 lb/mmBtu.
APPEARED.IN CO PL NC'E: 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 S02/mmBtu. The facility only accepts ultra-low
sulfur diesel(ULSD), as verified byfuel certifications. The facility also takes fuel.samples annually,
and the last sample indicated a sulfur content of 0.0074 wt. %.
Mr. livers thinks that the 0.0074 wt. %is due to the addition of new ULSD into an existing tank,
which previously contained a higher percentage sulfur fuel oil.
C. 15A NCAC 2D .0521 --VISIBLE EMISSIONSCONTROL IJ —visible
emissions from each emission source manufactured after 1 July 1971, shall not exceed 20% opacity
when averaged over a six-minute period.
APPEARED IN NC'E. The facility was not operating at the time of this inspection.
During the inspection, I did not see any indication of issues with visible emissions. Mr. Rivers stated
that he has never seen visible emissions while the turbines operate.
