I. 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.
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.
M. 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.
Throughputs:
2015 140,200
2014 202,023
2013 24,508
IV. INSPECTION SUMMARY: On 12 May 2016,I Joshua Harris,FRO DAQ, conducted a compliance
inspection of Duke Energy Progress—Blewett in Lilesville,Anson County. The facility can be remotely j
operated,so it is typically unmanned and inspections should be pre-planned. I met with Norbert"Nob" I[
Zalme,Environmental Coordinator, and Joe Rivers,Combustion Turbine Operator for an announced
inspection of the facility. The plant was not operating at the time, and was down for a week long j
maintenance outage. Mr.Zalme and Mr. Rivers Verified the FacFinder data,and Mr. Rivers pointed out
that the physical address for the plant was not correct. He stated that the "911"address is 2598 Power
Plant Road,and this update has been made in IBEAM. We discussed the upcoming renewal, and emission
inventory requirement, and Mr.Zalme stated that the emission inventory would be completed by William
"Bill"Horton. We had a brief discussion about the replacement of CAIR requirements with CSAPR
requirements in the facility's permit,and the plant continues to participate in allowance trading.
Mr.Rivers provided the required records,which were very well organized. The turbines typically only
operate for a few days during the colder months of the year, and the plant only operated for 42 hours in
2016. After reviewing the facility's records,Mr.Zalme showed me to the facility's burn pit which is used
to disposed of vegetative materials that are collected in the screens at the hydroelectric plant;there did not
appear to be any non-vegetative material present. Mr. Zalme described the notifications that are made
when the facility does burn,which includes the FRO. We then returned to the control room, and I
departed the facility shortly after. j

VI. APPLICABLE AIR QUALITY REGULATIONS:
i
A. 15A NCAC 2D .0202-PERMIT RENEWAL AND EMISSION INVENTORY REQIREMENT
—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 COMPLMNCE. The facility's permit expires on 31 January 2017, and the
application is due no later than 02 November 2016 Mr. Zalme is aware of this and stated that the
emission inventory will be completed by Mr. Bill Horton.
B. 15A NCAC 2D .0516—SULFUR DIOXIIDE EMISSIONS FROM COMBUSTION SOURCES—
S02 emissions from the CTs shall not exceed 2.3 lb/mmBtu.
i
APPEARED IN COMPLMNCE. The facility is permitted to combust No. 2 fuel oil up to 0.5 wt.%
suer, which has an AP-42 emission factor of 0.51 lb S021mmBtu. The facility only accepts ultra-low
su fur diesel(ULSD), as verified by fuel certifications. The facility also takes fuel samples annually,
and the last sample indicated a suer content of 0.0106 wt. %.
Mr. Rivers stated that the facility used to combust oil with a su fir content of 0.5 wt.Vo, and that the
tank was drained then refilled with ULSD when the facility made the switch. The higher suer
content in the sample may be due to the mixing of ULSD with any residual oil left in the tank when it
was drained and refilled. In any event, combustion offuel oil with this suer content will not exceed
the permit limit.

i
I
C. 15A NCAC 2D .0521—CONTROL OF VISIBLE EMISSIONS—VE<20%opacity.
APPEARED INCOMPLL4NCE. No emission sources were operating at the time of the inspection.
Mr. Rivers stated that he has never seen visible emissions while the turbines operate.
D. 15A NCAC 2D .0535—NOTIFICATION REQUIREMENT—Notify DAQ in the event of excess
emissions lasting longer than 4 hours.
APPEARED INCOMPLIANCE: There are no indications of excess emissions which would
require a notification by the facility. Mr. Zalme is well aware of the requirement, and there have not
been any complaints from local residents received by the facility or by DAQ.
E. 15A NCAC 2D .0540—PARTICULATES FROM FUGITIVE DUST EMISSION SOURCES—
Fugitive dust emissions shall not cause/contribute to substantive complaints or excessive VE across
property boundaries.
APPEARED IN COMPLIANCE: No fugitive dust concerns were noted during the inspection. All
roads are paved, and there have not been any complaints received by the facility or by DAQ.
i
F. 15A NCAC 2Q .0315—SYNTHETIC MINOR FACILITIES—Operate within the following limits
