SUBJECT: Air Permitting Applicability Determination for Emergency Generators
Compass Datacenters -Durham Facility
99 TW Alexander Drive, Durham, NC, Durham County
Applicability Determination Application No. 3502
Dear Adil Attlassy:
Dil'ector
This letter is written in response to your letter received December 4, 2019, requesting
confirmation that the addition of six Tier 2 diesel-fired 2 MW emergency generators (de-rated to 1.825
MW) and six diesel fuel storage belly tanks under each tank to be installed at the Subject facility in
addition to two existing Tier 2 diesel-fired 2 MW emergency generators (de-rated to 1.825 MW) and two
diesel fuel storage belly tanks under each tank remains exempt from air permitting requirements. If the
only permitted sources at the facility are generators, then the facility remains exempt from air
permitting requirements under rule 15A NCAC 2Q .0903 since the actual emissions will not exceed 100
tons of any one crlleria pollutant, 10 tons of any hazardous air pollutant (HAP), and 25 tons combined of
all HAP emissions.
Please be aware that exemption from air permitting requirements does not exempt this facility
from any Air Quality Regulations. Also, there may be other state, federal, or local regulations applicable
to the operations. If you have any questions, feel free to contact Dena Pittman, Permits Coordinator, at
919-791-4200.

Re: Request for Facility Exempt from Permitting per 15A NCAC 02Q .0903
Compass Datacenters -Durham Facility
Durham, Durham County, NC
Dear Mr. Stewart,
DEC -4 2019
R.n/cigh n n.cg1011aJ Office
Compass Datacenters (CDC) operates a datacenter at 99 TW Alexander Drive, in Durham, North Carolina
(the NC Datacenter). The NC Datacenter will be Tier Ill datacenter certified by the Uptime Institute,
which requires that the datacenter maintain no more than 1.6 hours of downtime per year as well as
N+ 1 redundancy providing at least 72 hour power outage protection. These standards require that CDC
maintain a certain level of electric power from emergency generators in case of any power outage.
Please note that the term "generators" and "engines" are used interchangeably in this letter.
At this time, CDC is proposing to construct, operate, and maintain the following equipment:
> Six (6) Tier 2 Diesel Fired 2 MW Emergency Generators de-rated by the manufacturer to
1.825MW; and
> Six (6) Diesel Fuel Storage Belly Tanks-under of each engine.
There are currently the following equipment onsite which were installed in 2012:
> Two (2) Tier 2 Diesel Fired 2 MW Emergency Generators de-rated by the manufacturer to
1.825MW; and
> Two (2) Diesel Fuel Storage Belly Tanks-under of each engine.
CDC is proposing to operate each generator for a maximum of 60 hours per year for the purposes of
maintenance checks, readiness testing, and non-emergency operations. Per DAQ guidance, 500 hours
per year maximum operation was used to estimate facility wide estimated emissions. Based on the
proposed non-fugitive site-wide emissions contained in Attachment 1, the emergency generators being
included in this project will not exceed permitting thresholds, thus allowing CDC to be exempt from
permitting.
Per lSA NCAC 2 Q .0901 facilities that are defined under this Section are exempt from requirements of
15A NCAC 02Q .0300 -Construction and Operating Permits. Per 15A NCAC 2 Q .0903 -Emergency
Generators and Station Reciprocating Internal Combustion Engines are exempted if they meet the
following:
~
COMPASS~
dalacenlers
"emergency generators and stationary reciprocating internal combustion engines at a facility
whose only sources that would require a permit are emergency generators and stationary
reciprocating internal combustion engines whose facility-wide actual emissions are less than
100 tons per calendar year of any regulated pollutant, 10 tons per calendar year of any
hazardous air pollutant, or 25 tons per calendar year of any combination of hazardous air
pollutants"
The only sources at the site are the eight emergency generators and associated belly tanks as shown in
Attachment 1. The emission of each pollutant are less than 100 tons per calendar year of any regulated
pollutant, 10 tons per calendar year of any HAP, and 25 tons per calendar year of any combination of
HAP.
CDC requests per 15A NCDC 2Q .0111 a written response from the DAQ concurring with the permit
exemption request as outlined above in this letter. If you have any questions regarding the information
in this letter, please feel free to contact me at ( 469) 208-8786 or Dana Norvell of Trinity Consultants at
[phone].

To Whom It May Concern:
With regards to Cummins Power Generation (CPG) manufactured diesel generator set model DQKAB Data Center
Continuous (DCC) rated for 60Hz operation and equipped with Cummins QSK60-G6 engine:
When tested under the following conditions:
Table 1
Fuel Specification: ASTM 0975 No. 2-0 Sl5 diesel fuel with 0.0015% sulfur content (by weight), and 42-48
cetane number.
Air Inlet Temperature: 77 °F
Fuel Inlet Temperature: 104 "F (at fuel pump inlet)
Barometric Pressure: 29.53 in. Hg
Humidity: NOx measurement corrected to 75 grains H20/tb. dry air
Based on engine emissions validation testing, the table below represents the nominal performance and exhaust
emissions data for the generator set listed above:

25% 50% 75% 100%
BHP @ 1800 RPM (60 Hz) 662 1324 1986 2647
POWER OUTPUT (KWe) 456 913 1369 1825
Fuel Consumption (Gal/Hr.) 45 74 99 125
Exhaust Gas Flow (CFM) 6108 9191 11415 13587
Exhaust Gas Temperature ("F) 750 820 837 877
HC (Total Unburned Hydrocarbons) 0.32 0.18 0.11 0.09
NOx (Oxides of Nitrogen as N02) 2.87 3.19 4.22 5.41
CO (Carbon Monoxide) 1.0 0.5 0.3 0.3
PM (Particulate Matter) 0.21 0.11 0.03 0.02
All Values are Grams/HP-Hour
Steady-State emissions recorded per 1S08178-1 during operation at rated engine speed (+/-2%) and stated
constant load (+/-2%) with engine temperatures, pressures and emission rates stabilized.
The NOx, HC, CO, and PM emission data tabulated here are representative of test data taken from a single engine
under the test conditions shown above. Data for the other components are estimated. This data is subject to
instrumentation and engine-to-engine variability. Field emissions test data is not guaranteed to these levels. Actual
field test results may vary due to test ambient, site conditions, installation, fuel specification, test procedures,

instrumentation and ambient correction factors. Engine operation with excessive air intake or exhaust restriction
beyond published maximum limits, or with improper maintenance, may result in elevated emission levels.
Values provided in the table below are representative of "Potential Site Variation" levels accounting for variances
as indicated above without consideration of improper generator set maintenance.

Atl Values in Gram/HP-hr
The engine used in this generator set is certified to Tier 2 emission requirements of U.S. EPA New Source
Performance Standards for stationary emergency engines under the provisions of 40 CFR 60 Subpart 1111 when
tested per IS08178 D2.
