I. DIRECTIONS TO SITE: In Laurinburg,take 74 West through Rockingham, and into Anson County.
After crossing the Pee Dee River,tam 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.
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 CONFERENCE: On 18 July 2018,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, and Joe Rivers,Combustion Turbine Operator. This was a planned
inspection due to the facility not always being manned. We discussed the following:
a) Verified the FACADER information: no changes are needed.
b) I reviewed the facility's records for fuel oil analysis, inspections and maintenance,and NOx
emissions. All were complete and up to date.
c) I inquired how often the facility burned the logs and other vegetative debris collected from their inlet
screens at the hydro plant. Mr.Rivers stated that they only burn once or twice a year. It usually takes
one full day to burn the material but sometimes if the wood is not dry enough it can take two.

d) Throughputs:
`Year FuelOi
2017 68,387
2016 68,410
2015 140,200
2014 202,023
2013 24,508
VI. INSPECTION SUMMARY:
Ms.Kashmer and Mr. Rivers led me on a tour of the facility which was not operating. I observed the
CTs but since they were not operating there was nothing to see. I observed the facility's emergency
generator that powers the microwave tower in the event of a power outage. I observed no issues with the
generator.
I also observed the burn area used by the operators of the hydro plant. The material to be burned
appeared to be mostly large logs and tree limbs. It did not appear to contain any non-vegetative material.
VII. PERMIT STIPULATIONS:
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 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 17V COMPLIANCE: The facility is permitted to combust No. 2 fuel oil up to 0.5 wt.%
suow, which has an AP-42 emission factor of 0.51 lb S02/mmBtu. 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 su fur content of 0.0085 wt. %.
Mr. Rivers thinks that the 0.0085 wt. %is due to the tank previously containing higher percentage
sulfur in the past being drained and the new ULSD being added to any residual oil left in the tank
after draining.
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 INCOMPLIANCE: 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 VE across
property boundaries.
APPEARED INCOMPLIANCE. 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(CAHt)—
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 SA, 5B,and 5C.
ORIS ID: 2707
a. 40 CFR 97 Subpart 5A—TRANSPORT RULE NOx ANNUAL TRADING

trading. This information was provided after the inspection via an email from William
Horton.
H. 15A NCAC 2Q.0315—SYNTHETIC MINOR FACILITIES—Operate within the following limits
to maintain S02 and NOx emissions less than 100 tons annually.Records of fuel use and NOx
emissions calculations. Annual reporting.

APPEARED INCOMPLIANCE: Records indicate 68,387gallons offuel oil have been combusted
in the last 12 months, as of 30 June 2018. The facility maintains fuel certifications on-site, and only
accepts ULSD. Fuel sampling indicates that the fuel oil currently on-site has a su f<r content of
0.0085 wt.%. NOx emissions for the last 12-month period were 1.6 tons, as of 30 June 2018. The
facility utilizes the EPA's ECMPS Client Tool to calculate emissions.
I. 15A NCAC 2Q.0317—LIMITATION TO AVOID PSD—Limit S02 and NOx emissions to 250
tons per consecutive 12-month period.
APPEARED IN COMPLIANCE: The facility complies with this stipulation by operating within its
Synthetic Minor limitations.
J. 15A NCAC 2Q .0102—FEDERAL AND STATE RULES APPLICABLE TO EXEMPTED
SOURCES—
a. NESHAP Subpart ZZZZ(Stationary Reciprocating Internal Combustion Engines)
—Emergency engine IEmGenMWT is subject. Requirements include installation of a
non-resettable hour meter,oil and filter change and hose and belt checks at 500
hours/annually,check spark plugs 1,000 hours/annually. 100-hour annual limit on
operation for maintenance, 50-hour annual limit for non-emergency use.
APPEARED IN COMPLMNCE: Periodic I&M is conducted as required, with the last
annual maintenance being completed on 14 July 2018. The engine was verified to have
a manufacture date of 13 November 2003, and we observed the non-resettable hour
meter. 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.
VIIL NON-COMPLIANCE HISTORY SINCE 2010: This facility has no negative compliance history.
IX. RISK MANAGEMENT (112r): This facility does not store any 112(r) subject materials above threshold
limits. Therefore, it is not required to maintain a written Risk Management Plan (RMP).
X. CONCLUSION AND RECOMMENDATIONS:
- Duke Energy Progress,LLC—Blewett appeared to be operating IN COMPLLANCE with their air
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.
