1) MACTs/GACTs:
The facility does not appear to be subject to any MACTs/GACTs at this time.

2) DIRECTIONS TO SITE:
From FRO take 401 S. to Wagram. Turn right on Old Wire Road (NC 144)just south of Wagram.
Stay on NC 144, (this road will cross over 151501) until you reach HWY 74. Turn right on HWY 74.
Just after crossing the Pee Dee River, turn right onto Power Plant Road. Travel approx a mile and
turn left onto Blewett Falls Road. The facility will be on the right.
3) SAFETY CONSIDERATIONS:
Required safety equipment includes, safety shoes, eye protection and hardhat. Open no doors and
touch no plumbing while the turbine is in operation.
4) FACILITY DESCRIPTION:
This facility has simple-cycle, natural gas-fired (low sulfur No. 2 fuel oil backup) combustion
turbines generating electricity in Anson County. The facility can produce 340 MW of electrical
power to retail distribution during periods of high demand or during emergencies. This facility uses
six Pratt and Whitney FT-8 Swift-Pao simple cycle gas turbine generator sets. Each of the six units
consists of two turbines, each equipped with water injection, and one generator. The two turbines
associated with each FT-8 do not have to operate simultaneously. The double-ended configuration
allows for greater efficiency during partial load usage. This plant operates as a "peaking" facility to
meet peak power demands on a daily or seasonal basis. Pollution control is demineralizer water
injection to control NOx. "Simple cycle gas turbine" means any stationary gas turbine that does not
recover heat from the gas turbine exhaust to either preheat the'inlet combustion air or to heat water or
generate steam.
The Plant Information (PI) System was installed at this facility for plant-wide monitoring and
analysis. The system handles the collection, storage, and retrieval of parametric data. It also acts as a
data server for Microsoft Windows-based client applications that operators, engineers, managers, and
other plant personnel use to view the plant data stored in the PI Data Archive.
The facility chooses to use a predictive emission monitor systems (PEMs)to monitor NOx emissions
in lieu of CEMs. The predictive emission monitor systems have been proven to be as accurate as the
CEMs and are in fact more economical from the cost and maintenance. The facility uses this software
program to monitor and determine NOx emissions from the gas turbines in real time. Continuous
NOx emission rate is determined based on vendor's data and turbine operating parameters.
5) INSPECTION SUMMARY:
On 23 May 2014, 1, Heather Carter, met with Mr. Frank Bokuniewicz, O&M Planner and Scheduler,
at the Anson facility to conduct an air quality compliance inspection. Mr. Shawn Fowler, facility
contact, was not on site. Mr. Bokuniewicz verified that the contacts information is correct except for
the invoice contact, which I will confirm with Khalil Porter, technical contact. He provided all
records for review, as required by the permit.
6) PERMITTED EMISSION SOURCES: No turbines were operating during the inspection.

7) REGULATORY/STIPULATION REVIEW:
A. 15A NCAC 2D .0521: CONTROL OF VISIBLE EMISSIONS — Subject sources: twelve
turbines (ES-lA&B thru ES-6A&B). VE is limited to 20% opacity for each turbine when
averaged over a 6 min period, except during startup, shutdown and malfunction.
APPEARED IN COMPLIANCE- Facility combusts primarily natural gas, and No. 2 fuel oil
only as backup. Both are clean burning fuels and as such the opacity should always be in
compliance with the 20 percent limitation. No turbines were operating during the inspection.
B. 15A NCAC 2D .0524: NSPS, 40 CFR PART 60, SUBPART KKKK— Subject sources: twelve
turbines(ES-lA&B thru ES-6A&B).

a. S02 emissions limit= max sulfur content will be </= 0.05%; S02 monitoring=demonstrate
fuel will not exceed potential of 0.06 Ibs S02/MMBtu by representative fuel sampling; S02
reporting= submit semi-annual excess emissions reports for all periods including startup,
shutdown, and malfunction.
APPEARED IN COMPLAINCE- The facility initially demonstrated compliance with the
NSPS limits based on source tests reviewed and approved by the Raleigh Central Office.
Fuel oil sulfur content is determined by representative sampling after every load is added to
the storage tank. The most recent analysis showed 4.8 ppm S in Tank #1 and 5.2 ppm S in
Tank#2. Reports have been received on time and appear complete and valid.
b. NOx emission limits= 25 ppm at 15 percent 02 when firing NG or 74 ppm at 15 percent 02
when firing No. 2 fuel oil; NOx monitoring= shall install, calibrate, maintain, and operate a
continuous monitoring system;NOx reporting= submit semi-annual excess emissions reports
for all periods including startup, shutdown, and malfunction.
APPEARED IN COMPLIANCE- The facility chose to use a Predictive Emissions
Monitoring System (PEMS)that uses the water-to-fuel ratio to predict NOx emissions, based
on testing to establish the water-to-fuel curve. The PEMS activates an alarm if NOx
emissions exceed 25ppm for more than 60 seconds (once water flow is established) and if at
720 seconds the emissions still exceed then the unit automatically shuts down in order to
avoid exceeding the NOx limit for the rolling 240 minute period. Reports have been
submitted on time and appear complete and valid.
C. 15A NCAC 2D .0530 PREVENTION OF SIGNIFICANT DETERIORATION- Subject sources:
twelve turbines (ES-lA&B thru ES-6A&B). CO total emissions shall not exceed 405.5 tons/12 mtln
period. Each unit shall not exceed 1230 firs run time on natural gas or 710 firs run time on No. 2 fuel
oil(</=0.002% S),not including startup/shutdown time.
APPEARED IN COMPLIANCE- The 12 mth rolling total CO emissions (May 2013 to April
2014)was 51.98 tons. All units were below the hour run time limit for this same period, 331 firs on
NG and 62 hrs on fuel oil being the highest any one unit ran.
D. 15A NCAC 2Q .0317 OF 2D .0530: PSD AVOIDANCE- Subject sources: twelve turbines (ES-
IA&B thru ES-6A&B). NOx limit of 245 TPY. Must record # of startup/shutdowns per day.
Calculate and record NOx emissions daily. Submit a summary rpt semi-annually.
APPEARED IN COMPLIANCE-Records of startup/shutdown and daily NOx emissions appeared
valid and complete. Total NOx emissions from May 2013 to April 2014=60.23 tons. Reports have
been received on time and appear complete and valid.
E. 15A NCAC 2Q .0400: PHASE 11 ACID RAIN REQUIREMENTS- Subject sources: twelve
turbines (ES-1A&B thru ES-6A&B). There are no specified S02 Allowance Allocations and NO,
limits under this rule.
APPEARED IN COMPLIANCE-The facility provided data that shows they had 0 S02 emissions
in 2013.
F. 15A NCAC 2Q.2403: CLEAN AIR INTERSTATE RULES (CAIR)FOR NOx- Subject sources:
twelve turbines (ESI-A&B thru ES6-A&B). NOx emission limits= There are no specified NOx
emissions allowance allocations in the permit. Facility must comply with the approved CAIR
Permit Application that is part of this permit.

APPEARED IN COMPLIANCE-The facility provided data that shows they emitted 47 tons NOx
and held 133 allowances for 2013.
G. 15A NCAC 2Q .2405: CLEAN AIR INTERSTATE RULES (CAIR) FOR NOx OZONE
SEASON- Subject sources: twelve turbines (ESI-A&B thru ES6-A&B). NOx emission limits=
There are no specified NOx emissions allowance allocations for ozone season in the permit. Facility
must comply with the approved CAIR Permit Application that is part of this permit.
APPEARED IN COMPLIANCE-The facility provided data that shows they emitted 23 tons NOX
and held 93 allowances for 2013.
H. 15A NCAC 2Q .2404: CLEAN AIR INTERSTATE RULES (CAIR)FOR 5O2- Subject sources:
twelve turbines (ESI-A&B thru ES6-A&B). SO2 emission limits= There are no specified S02
emission allowance allocations in the permit. Facility must comply with the approved CAIR Permit
Application that is part of this permit.
APPEARED IN COMPLL4,NCE-The facility provided data that shows they had 0 SO2 emissions
in 2013.
