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.
U. 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.
Throughputs:
2016 68,410
2015 140,200
2014 202,023
2013 24,508
IV. INSPECTION Si-NM Y: On 14 July 2017, Mike Thomas, and I,Joshua Harris, both of FRO DAQ,
conducted a compliance inspection of Duke Energy Progress—Blewett in Lilesville,Anson County. The
facility can be remotely operated, so it is typically unmanned and inspections should be pre-planned. We
met with Kim Kashmer, Lead EHS Professional, and Joe Rivers, Combustion Turbine Operator for an
announced inspection of the facility;the plant was not operating at the time. Ms. Kashmer and Mr.
Rivers verified the facility contact information and no changes were noted. Mr. Rivers provided the
required records,which were very well organized. After reviewing the facility's records,Ms.Kashmer
and Mr. Rivers showed us to the facility's bum 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. We also observed the facility's insignificant emergency generator, which provides
emergency power to the microwave tower in the event of a power outage. We then departed the facility.

VI. APPLICABLE AIR QUALITY REGULATIONS:
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 COMPLLANCE. The facility's permit was recently renewed on 04 January 2017,
and the application was received on time_ The renewal application will be due no later than 02
October 2024, and must include an emission inventory for CY2023.
B. 15A NCAC 2D .0516—SULFUR DIOXIDE EMISSIONS FROM COMBUSTION SOURCES—
SOz emissions from the CTs shall not exceed 2.3 lb/mmBtu.
APPEARED IN COMPLIANCE: The facility is permitted to combust No. 2 fuel oil up to 0.5 wt.%
sulfur, which has an AP-42 emission factor of 0.51 lb S02/mmBtu. The facility only accepts ultra-low
sulfur diesel(ULSD), as verified by fuel certifications. The facility also takes fuel samples annually,
and the last sample indicated a su m content of 0.0087 wt. %.
Mr. Rivers stated that the facility used to combust oil with a sulfur content of 0.5 wt.% and that the
tank was drained then refilled with ULSD when the facility made the switch. The higher sulfur
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 sulfur content will not exceed
the permit limit.

C. 15A NCAC 2D .0521 —CONTROL OF VISIBLE EMISSIONS—VE<20% opacity.
APPEARED IN COMPLIANCE: 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 IN COMPLIANCE: There are no indications of excess emissions which would
require a notification by the facility. Ms. Kashmer and Mr. Rivers are 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 VIE 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.
F. 15A NCAC 2D .2400—CLEAN AIR INTERSTATE RULES (CAIR)—
_
No requirements under these rules as they have been replaced by the Cross State Air Pollution Rules
(CSAPR).
G. CROSS STATE AIR POLLUTION RULES (CSAPR)PERMIT REQUIREMENTS—The
Permittee shall comply with all applicable requirements of 40 CFR 97 Subparts 5A, 5B, and 5C.

H. 15A NCAC 2Q .0315—SYNTHETIC MINOR FACILITIES—Operate within the following limits
to maintain SO2 and NOx emissions less than 100 tons annually.Records of fuel use and NOx
emissions calculations. Annual reporting.
APPEARED IN COMPLIANCE: Records indicate 75,539 gallons of fuel oil have been combusted
in the last 12 months, as of 30 June 2017. The facility maintains fuel certifications on-site, and only
accepts ULSD. Fuel sampling indicates that the fuel oil currently on-site has a sulfur content of
0.0087 wt.%. NOx emissions for the last 12-month period were 3.72 tons, as of 30 June 2017. We
asked to see how the calculations were made for emissions, to verify the correct Part 75 emission
factors were being used. Bill Horton, Lead Environmental Specialist,provided a copy of the
calculation documents, and the calculations are made using the tool in ECMPS, which has built-in
emission factors per Part 75. The last annual report was received on 23 January 2017, and indicated
compliance.
I. 15A NCAC 2Q .0317—LIMITATION TO AVOID PSD—Limit SO2 and NOx emissions to 250
tons per consecutive 12-month period.

operation for maintenance, 50-hour annual limit for non-emergency use.
APPEARED IN COMPLIANCE: Periodic I&M is conducted as required, with the last
annual maintenance being completed on 13 September 2017. We reminded Ms. Kashmer
and Mr. Rivers that this is an annual requirement and that the annual maintenance would
need to be completed by the end of this year. We also provided Mc. Kashmer with a copy
of the generic permit language for NES11AP Subpart 4Z. The engine was verified to have
a manufacture date of 13 November 2003, and we observed the non-resettable hour
meter, which read 758.4 hours during the inspection. Ms. Kashmer mentioned that there
is a plan to move the microwave tower and engine closer to the turbines at some point in
the future.

permit at the time of this inspection.
PINK SHEET ADDITIONS:
For the inspector,the previous fuel oil limit of 1,602,175 gallons per 12-month period(at 0.5
wt.% sulfur) can be used to verify compliance with the 100 TPY S02 limit.
- At next permit action, include a recordkeeping requirement for 12-month SOZ emissions.
