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
(SR1748). 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.
H. 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 30 November 2021,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
from the dam periodically(right-of-way maintenance burns). 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 debris collection and burning. The material
collected appeared to be mostly large logs and tree limbs. It did not appear to contain any non-vegetative
material.

sulfur, which has an AP-42 emission factor of 0.51 lb SO2/mmBtu. The facility only accepts ultra-low
sulfur diesel(ULSD), as verified by fuel certifications. The facility also takes fuel samples from the
storage tank annually, and the last sample taken on 11 September 2021 indicated a sulfur- content of
0.0073 wt. %.
