Emissions Calculations

Dear	Ms.	Fortin:	

Anadarko	Petroleum	Corporation	(Anadarko)	submitted	an	application	for	a	pre‐construction	permit	

and	an	operating	permit	for	conducting	exploratory	drilling	and	associated	activities	on	the	Outer	

Continental	Shelf	(OCS)	of	the	Eastern	Gulf	of	Mexico	(EGOM)	in	September	2013.		The	proposed	project	

primarily	consists	of	three	phases‐	(1)	the	drilling	phase,	(2)	the	well	completion	phase,	and	(3)	the	

production	well	maintenance	(remedial	well‐work)	phase.		The	application	was	deemed	complete	on	

February	20,	2014.		With	this	submittal,	Anadarko	is	proposing	to	add	an	additional	diesel	storage	tank	

(DR‐FT‐19)	associated	with	the	emergency	generator	(DR‐GE‐01)	and	revise	emission	calculations	for	

the	existing	fast	rescue	craft	engine	(DR‐FR‐01).	

The	emergency	generator	diesel	tank	will	be	used	to	store	and	supply	ultra	low	sulfur	diesel	fuel	to	the	

emergency	generator.		The	tank	is	identified	as	a	horizontal	tank	with	the	maximum	product	storage	

capacity	of	10	cubic	meters.		For	estimating	emissions,	the	maximum	throughput	of	the	tank	was	

estimated	to	be	13,208	gallons	based	on	the	fuel	usage	rate	of	the	emergency	generator	and	the	

maximum	operation	of	100	hours	per	year.		The	volatile	organic	compound	(VOC)	emissions	from	this	

tank	were	estimated	using	TANKS	4.09d	program.		An	output	of	TANKS	4.09d	program	is	attached	with	

this	submittal.		As	shown	in	the	TANKS	4.09d	program	output,	the	proposed	change	results	in	a	minimal	

increase	(i.e.,	one	pound	per	year)	of	VOC	emissions.		Due	to	minimal	increase	in	VOC	emissions,	

revisions	to	the	previously	submitted	BACT	analysis	as	well	as	the	air	dispersion	modeling	analysis	are	

not	warranted.		

Anadarko	is	also	revising	the	potential	to	emit	calculations	for	the	existing	fast	rescue	craft	engine	(DR‐

FR‐01).		The	emission	factors	for	total	particulate	matter	(PM),	particulate	matter	with	an	

aerodynamic	diameter	less	than	10	microns	(PM10),	particulate	matter	with	an	aerodynamic	

diameter	less	than	2.5	microns	(PM2.5),	nitrogen	oxides	(NOX),	and	carbon	monoxide	(CO)	were	

estimated	based	on	EPA	Marine	Tier	2	emission	factors.		However,	based	on	recent	information,	use	of

AP‐42	emission	factors	is	more	appropriate	for	estimating	PM,	PM10,	PM2.5,	NOx,	and	CO	emissions	

from	the	existing	fast	rescue	craft	engine.		Consistent	with	previous	guidance	from	EPA,	all	of	the	

particulate	matter	emissions	from	the	diesel	combustion	were	assumed	to	be	less	than	1	micron.		
EPA	Region	4	–	Page	2	

September	10,	2014	

Hence,	emissions	of	PM,	PM10,	and	PM2.5	were	assumed	to	be	equal.		Note	that	Anadarko	is	not	

requesting	to	revise	the	fuel	limits	associated	with	each	operating	scenario.		Since	emissions	from	the	

drillship	were	estimated	based	on	the	fuel	limits,	the	proposed	revision	results	in	no	change	in	

emissions.		Hence,	revisions	to	the	previously	submitted	BACT	analysis	as	well	as	the	air	dispersion	

modeling	analysis	are	not	warranted.		

The	proposed	changes	are	marked	with	yellow	background	in	the	attached	supporting	documents.		

Anadarko	also	attached	EUD‐2	form	for	the	new	diesel	storage	tank.		If	you	have	any	questions	or	

require	additional	information,	please	do	not	hesitate	to	contact	me	at	(832)	636‐1273	or	Mr.	Rahul	

Pendse,	Trinity	Consultants	at	(225)	346‐4003.

Analysis:	Control	of	Emissions	from	Nonroad	Diesel	Engines,	EPA420‐R‐03‐008,	April	2003.		

Emissions	of	Hydrogen	sulfide	(H2S),	total	reduced	sulfur	(TRS),	and	reduced	sulfur	compounds	

resulting	from	sulfur	content	in	the	fuel	are	negligible.	

The	maximum	hourly,	daily,	and	annual	emissions	from	the	life	boat	engines	are	calculated	as	described	

below:	

Maximum Hourly Emissions – The	maximum	hourly	emissions	for	the	life	boats	are	calculated	

based	on	1	hour	of	operation	per	engine.		

Maximum Daily Emissions – The	maximum	daily	emissions	for	the	life	boats	are	calculated	

based	on	1	hour	of	operation	per	day	per	engine.

Annual Emissions –	The	annual	emissions	for	the	life	boats	are	calculated	based	on	100	hours	

of	annual	operation	per	engine.		

Proposed Operating Limits:	

Since	these	emission	units	will	be	a	part	of	drillship‐wide	fuel	consumption	limit,	no	separate	fuel	limit	

is	required	to	demonstrate	compliance.		Anadarko	will	maintain	adequate	records	to	comply	with	

proposed	daily	and	annual	operation	limits.			

3.3.5. Fast Rescue Craft (DR-FR-01) 

The	drillship	consists	of	one	fast	rescue	craft	with	55	HP	power	rating	and	SABB‐L4	Turbo	engine.		The	

specification	sheet	for	the	representative	engine	is	provided	in	Appendix	G‐1.		Emissions	are	generated	

as	a	result	of	combustion	of	diesel	fuel	used	in	the	engine.			

Emissions Factors	 –	 The	 sources	 of	 emission	 factors	 used	 to	 estimate	 emissions	 for	 the	 engine	 are	

summarized	below.	

AP‐42, Section 3.3.		Gasoline and Diesel Industrial Engines	–	Particulate	matter	(PM,	PM10,	and	

PM2.5),	NOX,	VOC,	CO,	and	HAP	emissions	estimates	for	the	fast	rescue	craft	are	based	on	AP‐42,	

Section	3.3	emission	factors.		Based	on	AP‐42	guidance,	all	of	the	particulate	matter	is	assumed	to	be	

less	than	1	μm.		Therefore,	it	is	assumed	PM2.5	=	PM10	=	PM.			All	of	the	TOC	is	assumed	to	be	VOC.		

TOC	emission	factor	has	been	calculated	as	the	sum	of	exhaust	and	crankcase	emission	factors.		An	

average	BSFC	of	7,000	Btu/HP‐hr	has	been	used	to	convert	emission	factors	from	lb/MMBtu	to	

lb/HP‐hr.	

EPA Regulations – CO2,	CH4	and	N2O	emission	factors	are	obtained	from	40	CFR	98	Subpart	C,	Table

C‐1	(Default	CO2	Emission	Factors	and	High	Heat	Values	for	Various	Types	of	Fuel)	and	Table	C‐2	

(Default	CH4	and	N2O	Emission	Factors	for	Various	Types	of	Fuel).		Emission	factor	for	CO2e	has	

been	calculated	using	the	GWPs	obtained	from	40	CFR	98	Subpart	A.				

EPA Guidance Documents	–	Lead	emission	factor	is	obtained	from	EPA	guidance	document:

Locating	and	Estimating	Air	Emissions	from	Sources	of	Lead	and	Lead	Compounds,	EPA	454/R‐98‐

006,	May	1998,	Section	5.2.2.		Emission	factor	for	distillate	oil‐fired	gas	turbines	was	used	as	a	

surrogate	for	distillate	oil‐fired	engines	due	to	lack	of	emission	factors.

3.3.8. Storage Vessels (DR-FT-01 through DR-FT-19) 

The	drillship	includes	following	fuel	storage	tanks:	

Diesel	fuel	storage	vessels	(17)	–	various	capacities	

Helicopter	fuel	storage	tanks	(2)	–	2,900	gallons	each	

Emissions	from	all	storage	vessels	on	the	Drillship	have	been	estimated	using	EPA’s	TANKS	4.0.9d	

(TANKS)	program.		Default	TANKS	properties	for	distillate	fuel	oil	No.	2	were	used	to	model	the	contents	

of	the	diesel	tanks.		Default	speciation	profile	and	physical	and	chemical	properties	for	Jet	Naphtha	(JP‐

4)	in	TANKS	4.09d	program	are	used	to	model	the	contents	of	the	helicopter	fuel	storage	tanks.		Refer	

Appendix	G‐4	for	Tanks	program	output.	

The	maximum	diesel	fuel	usage	for	the	Drillship	is	123	cubic	meters/day.		To	represent	conservative	

scenario,	a	throughput	equal	to	twice	the	fuel	usage	restriction.		It	was	assumed	that	all	fuel	will	be	

loaded	into	the	largest	tank	DR‐DT‐04	to	calculate	the	maximum	total	tank	VOC	emissions	(tpy)	on	the	

drillship.	

Maximum	hourly	emissions	was	calculated	using	EPA	TANKS	4.09d	program	for	the	month	of	June,	since	

June	results	in	the	highest	daily	emissions.	

3.3.9. Drillship Fugitive Emissions (DR-FE-01) 

The	fugitive	emissions	on	the	drillship	occur	from	the	diesel	fuel	lines	and	associated	components.		

Emissions	from	the	lines	are	based	on	an	estimated	number	of	components	and	heavy	oil	emission	

factors	from	Table	2‐4	of	the	EPA	Protocol	for	Equipment	Leak	Emission	Estimates.		Since	the	exact	

component	counts	were	not	available,	component	count	were	conservatively	estimated	using	

engineering	judgments	and	based	on	the	component	counts	for	the	other	drillship	currently	leased	by	

Anadarko.			

Operating Parameters	–	The	maximum	hourly,	daily	and	annual	fugitive	emissions	are	calculated	

based	on	the	following	operating	parameters.		

Maximum Hourly Emissions	–	Maximum	hourly	emissions	are	estimated	based	on	one	hour	

operation.	

Maximum Daily Emissions	–	Maximum	daily	emissions	are	estimated	based	on	24	hrs/day	

operation.	

Annual Emissions	–	Maximum	annual	emissions	are	estimated	based	on	4,800	hrs/year	operation.	

3.3.10. Painting Operations (DR-PO-01) 

As	part	of	maintenance	activity,	painting	happens	on	the	BlackHawk	drillship.	PM/PM10/PM2.5,	VOC,	and	

HAP	emissions	are	calculated	based	on	the	average	thinner	usage,	average	primer	usage,	30%	air	

assisted	spray	transfer	efficiency	and	paint/primer	usage	of	maximum	40	gal/day	and	thinner	usage	of

Engine specifications provided in a needs list spreadsheet by Ms. Sara Carlson (Anadarko) to Mr. Rahul Pendse (Trinity) 

via email on August 7, 2013.

Per 40 CFR 80.510(b), Anadarko proposes the use of Ultra Low Sulfur Diesel (ULSD) for all diesel combustion 

sources. Therefore, emissions have been calculated based on a maximum sulfur content of 15 ppmw in diesel fuel 

assuming that 98 wt.% of sulfur in the fuel is oxidized to SO2 and 2 wt.% of sulfur in the fuel is oxidized to H2SO4 based 

on AP-42 Appendix A, table 3.4.1 footnote e and Draft Regulatory Impact Analysis: Control of Emissions from Nonroad 

Diesel Engines, EPA420-R-03-008, April 2003. 

Operating time for this engine has been assumed to be 1 hr/day and 100 hrs/year.

All TOC is assumed to be VOC. TOC emission factor has been calculated as the sum of exhaust and crankcase emission 

factors.

Based on footnote b of AP-42 Chapter 3, Table 3.3-1, Emission Factors for Uncontrolled Gasoline and Diesel Industrial 

Engines (October 1996). Per footnote b of Table 3.3-1, all PM is assumed to be < 1 um, therefore, assumed PM2.5 = 

PM10 = PM. 

Emission factors are based on AP-42, Chapter 3, Table 3.3-1, Emission Factors for Uncontrolled Gasoline and Diesel 

Industrial Engines (October 1996). Emission factors for diesel fuel are used.

Lead emission factor (2.9x10-5 lb/MMBtu) is obtained from EPA guidance document: Locating and Estimating Air 

Emissions from Sources of Lead and Lead Compounds, EPA 454/R-98-006, May 1998, Section 5.2.2. Emission factor 

for distillate oil-fired gas turbines is used as a surrogate for distillate oil-fired engines due to lack of emission factors. 

An average brake-specific fuel consumption (Brake Specific Fuel Consumption (BFSC)) of 7,000 Btu/hp-hr is used to 

convert from lb/MMBtu to lb/hp-hr.

Note:

[1] For all diesel tanks on the drillship, the annual "capped" emissions of all the diesel tanks grouped together are calculated based on a throughput of 123 cubic meter/day * 2 * 200 days/yr * 264.17 * 1.16 = 15,076,710 gal/yr (approximately with 16% safety factor)

[4] For all three jet fuel tanks, throughput is 450 GPD based on the email from Ms. Sara Carlson (Anadarko) to Rahul Pendse (Trinity) on December 20, 2012. 

[5] Red/Primer was selected as the most appropriate shell color in Tanks 4.09d program, as yellow is not an option in TANKS 4.09d program.

[6] Based on EPA-approved TANKS 4.09d program. 6604500

[7] The largest tanks DR-FT-05 and DR-FT-06 on the drillship are chosen to calculate the drillship tanks annual emissions. 6604500

[8] Tank volume 21,000 gal is provided by Ms. Sara Carlson (Anadarko) to Mr. Rahul Pendse (Trinity) via email on March 8, 2013.

[2] Total Standing Losses = (maximum hourly standing losses for biggest tank on the supply boat) * (24 hrs/day) * 200 days/yr. Only the standing losses are calculated since diesel from all tanks on the supply boat will only be unloaded into the drillship tanks and no 

filling of tanks occurs on the supply boat.

[3] Total Standing Losses = (maximum hourly standing losses for biggest tank on the anchor handling boat) * (24 hrs/day) * 200 days/yr. Only the standing losses are calculated since diesel from all tanks on the anchor handling boat will only be unloaded into the drillship 

tanks and no filling of tanks occurs on the anchor handling boat.

Well Completion Total Emissions from Tanks

Standing Loss Total Emissions

The average diesel fuel usage for the drillship is 774 bbl/day. For conservative assumption, a throughput equal to twice the average fuel usage restriction of 774 bbl/day is used and it is assumed that all fuel is 

loaded into the largest tank DR-FT-05 to calculate the maximum total tank VOC emissions (tpy) on the drillship.
