Re:	 IPANM	 comments	 to	 OAQPS	 Oil	 and	 Natural	 Gas	 Sector	 liquids	 unloading

Whitepaper

Dear	Sir	or	Madam;	

The	 Independent	Petroleum	Association	of	New	Mexico	 (‘IPANM’)	appreciates	 this	

opportunity	to	comment	to	the	EPA	Office	of	Air	Quality	Planning	&	Standards	(hereinafter	

‘EPA’)	whitepaper	on	Oil	and	Gas	Sector	liquids	unloading of	April	2014.	

Preliminary	matters:	

Without	adequate	research	and	an expert	understanding	of	 the	issues,	it	would	be	

unethical	 for	 the	 EPA to	 move	 forward	 with	 promulgating	 methane	 reductions	 policy	 or	

rules	 at this	 time.	 The	whitepapers	 and	 studies	 cited	 therein	 do	 not	 appreciate	 that	 the	

issues	 around	 methane	 reductions	 are complex	 and	 very	 dynamic.	 In	 fact,	 since	 the	

introduction	 of	 the	 First	 Assessment	 Report	 (FAR)	 of	 the	 Intergovernmental	 Panel	 of	

Climate	 Change	 (IPCC	 1990),	 there	 has	 been	 vigorous	 discussion	 about	 whether	 global	

warming	potential	(GWP)	to compare different	gases	on	a	CO2	equivalent	scale should	be

the	accepted	methodology	to	understand	the	true	impacts	of	methane.

1 2 As	recently	as	last	

month,	MIT	 researchers	 published a	letter,	 titled,	 “Climate	impacts	of	energy	 technologies	

depend	on	emissions	timing”	in	Nature	Climate	Change stating	that	the	static	nature	of	GWP	

to	compare	gases	with	differing	radiative	efficiencies	and	atmospheric	lifetimes	has	led	to	

‘major	 shortcomings’	 in	 understanding	 energy	 technology	 valuations3. However,	 in	 the	

urgency to	complete	methane	reductions	regulations	by	 the	end	of	2016,	 the	Whitehouse	

has	directed	the	EPA	draft	whitepapers	and convene	peer	review	panels	to	give	the	agency	

a	‘robust	understanding’	of	the	issues.		IPANM	would	contend	that	these	whitepapers	were	

obviously	rushed,	had	a	limited	and	biased	selection	of	studies	and	we	question	the	efficacy	

of	the	peer	review	process.		We	hope	that	the	agency	would	proceed	with	this	process	in	a	

manner	 that allows	 for	 true	 stakeholder	 involvement	 and	 opportunity	 for	 comment as	

required	in	the	federal Administrative	Procedures	Act. Finally,	we	would	urge	the	agency	to	

use	the	resources	and	expertise	available	at	the	New	Mexico	Petroleum	Recovery	Research	

Center	 to	learn	about	 the	unique	characteristics	of	oil	and	gas	operations	in	 the	San	 Juan	

and	 Permian	 basins.	 Within	 the	 PRRC	 is	 the Research	 Partnership	 to	 Secure	 Energy	 for	

America	 (RPSEA),	 Small	 Producer	 Program which	is	 a	public/private	 partnership	 funded	

by	 the	U.S.	DOE	 through	 the	National	Energy	Technology	Laboratory.	The	Small	Producer	

Program	aims	 to	develop	and	apply technology	 that	enhances	small	producer	production,	

and	 thereby	 contributes	 to	 the	 nation’s	 energy	 supply.	 The	 PRRC/New	Mexico	 Tech	 was

behalf	of	small	oil	and	gas	producers,	 for	whose	benefit	our	organization	was	established.		

IPANM	would	also	be	happy	to	provide	additional	input	to	the	EPA	in	the	development	of	

policy,	rules	and	regulation	on	methane	reduction	strategies.		

Who	is	IPANM:

The	Independent	Petroleum	Association	of	New	Mexico,	IPANM,	represents	several	

hundred	independent	oil	and	gas	producers	who	live,	work	and	employ	New	Mexicans.		We	

are	small,	with,	on	average,	25	employees	who	often	wear	multiple	proverbial	hats,	but	we	

provide	enough	revenue	to	the	State	of	New	Mexico	to	support	31%	of	the	General	Fund4.		

We strive	to	be	stewards	of	the	land	in	a	state	where	nearly	41.8%	of	the	land	is	federally	

owned.		The	Bureau	of	Land	Management	New	Mexico	office	manages	one	of	the	largest	oil	

and	 gas	 programs	 in	 the	 agency	 controlling	 13.4	 million	 acres	 of	 public	 lands	 and	 26	

million	 subsurface	 acres	 of	 federal	 oil,	 natural	 gas,	 and	 minerals.	 	 There	 are	 currently	

30,561	active	wells	on	 federal	lands5 ranking	New	Mexico	sixth	in	crude	oil	production	in	

the	nation	in	20136.	New	Mexico’s	marketed	production	of	natural	gas	accounted	for	4.8%	

of	U.S.	marketed	 natural	 gas	 production	in	 2012,	 despite	 a	 decline	in	 production	 of	 20%	

between	 2007	 and	 20127. According	 to	 the	 Office	 of	 Natural	 Resources	 Revenue,	 in	 FY	

2013	 the	 Federal	 Government	 disbursed	 $478,732,193.90	 in	 revenues	 to	 New	 Mexico8,	

which	is	only	48%	of	the	total	royalty	revenues	collected	for	oil	and	gas	operations	on	NM	

federal	lands.

The	 process	 by	which	 these	whitepapers	were	 developed	was	 flawed	 and	 requires	more	

study	and	expert	understanding	of	the	issues.	

Regulation	in	the	air	quality	arena	is	not	new,	however,	IPANM	would	contend	that	

the	 process	 by	 which	 the	 Whitehouse,	 through	 the	 EPA	 and	 the	 BLM, is	 seeking	 to	

implement	 new	 or	 substantially	 expanded	 methane	 reduction	 strategies,	 is	 not	 tenable9.

Note	 that	 IPANM	 does	 not	 contest	 the	 authority	 of	 the	 EPA	 to	 regulate	 Greenhouse	 Gas	

emissions10,	of	which	methane	is	a	part	of	those	emissions11.		The	authority	under	the	Clean	

Air	 Act	 and	 a	 growing	 body	 of case	 law,	 grants	 the	 complex	 balancing	 of	 “national	 and	

international	 policy	 against	 environmental	 benefit,	 our	 nation’s	 energy	 needs	 and	 the	

possibility	 of	 economic	 disruption”	 solely	 on	 the	 Environmental	 Protection	 Agency.	 See,	

American	Electric	Power	v.	Connecticut,	131	S.Ct.	2527,	564	U.S.	 ____	,slip	op.	10-174	at	13	

(2011).		Indeed,	through	out	the	American	Electric decision,	the	US	Supreme	Court	justices	

refer	 to	 the	 EPA	 as	 the	 “experts”12 in	 greenhouse	 gas	 and	 air	 quality	 matters.	 In	 the	

Administration’s	“2014	Climate	Action	Plan:	Strategy	 to	reduce	methane	emissions13”,	the	

President	 orders	 the	BLM,	 the	EPA,	USDA,	DOE	and	even	international	agencies	 to	 target	

key	 sources	 including	 landfills,	 coalmines,	 agriculture	 and	 the	 oil	 and	 gas	 sector	 and	 to	

																																																							 9 IPANM does contend that the statutory jurisdiction to regulate methane reductions lies exclusively with the EPA 

and not the BLM which is attempting to regulate methane emissions under the guise of a prevention of waste 

legal theory. 10 In Massachusetts v. EPA, 549 U. S. 497 (2007), the US Supreme Court held that the Clean Air Act, 42 U. S. C. 

§7401 et seq., authorizes federal regulation of emissions of carbon dioxide and other greenhouse gases, 

including methane.

11 IPANM does, however, contest the science behind the policy for reducing human caused methane sources. 

Several of our members pointed out in response to this exercise that the science of global warming and impacts 

of human activities have not been settled yet. In 2012, CH4 accounted for about 9% of all U.S. greenhouse gas 

emissions from human activities. But water vapor in the atmosphere is responsible for 95 percent ofthe 

greenhouse effect and CO2 is responsible for 3.6 percent. A study from MIT reported on 5/30/07 said that 97% 

of all greenhouse gases are naturally occurring, and the remaining 3% are caused by man. So methane is only 

3% of the 9%. Insignificant. 12 American Electric Power v. Connecticut, 563 US _____, slip op. at p. 3, 16,17,18 13 March 2014 Climate Change Strategy: Reduction of Methane Emissions, found at

promulgate	rules	to	reduce	methane	emissions.		The	White	House	specifically	directs14 the	

BLM	to	propose	updated	standards	to	reduce	venting	and	flaring15, and mandated	the	EPA	

to	draft	white	papers	focusing	on	technical	issues relating	to	methane	emissions	from “oil	

and	 co-producing	wells,	liquids	 unloading,	leaks,	 pneumatic	 devices	and	 compressors”	to	

“solicit	 input	 from	 independent	 experts16” (hereinafter	 referred	 to	 as	 the	 EPA	 methane	

papers).	 	 The	 EPA	 was	 further	 ordered	 to	 use	 these	 documents	 to	 “solidify	 its	

understanding	of	these	potentially	significant	sources	of	methane.”	

The	EPA	methane	papers	came	out	 for	peer	review	and	comment	one	month	after	

the	release	of	the	Whitehouse	report	with	only 60	days17 to	comment on	nearly	300	pages	

of	technical	data.		The	Whitehouse report also	directed	the	agency	to	convene peer	review	

panels, which	was	done, but	those	panels	only	consist	of 5	persons	per	panel,	and not	one	

single	 small	 independent	 was	 included	 on	 any	 panel.	 It	 is	 interesting	 to	 note	 that	 the

Environmental	 Defense	 Fund,	 however,	 was	included	 on	 every	 panel thereby	 giving	 that	

group	a	significant	voice	in	this	process.	

From a	 detailed	 review	 of	 the	EPA	methane	 papers,	it	is	 obvious	that	 the	 authors	

were	 clearly	 limited,	 probably	 due	 to	 time	 constraints,	 to	 a	 small	 subset of	 studies	 that	

were	 often	 out	 of	 date,	 had	 poor	 sampling	 criteria,	 had	 wildly	 inaccurate	 extrapolation

Flaring proposal and would urge both the BLM and this agency to include IPANM, PRRC or RPSEA (see 

discussion above) in future stakeholder discussions. 16 Id. at 8 par. 2. 17 60 days to read and digest nearly 300 pages of technical information was very difficult. To require industry to 

commission, prepare and present data to augment the very weak studies relied upon by the EPA was 

impossible. In addition, the timeframe set did not avail IPANM the ability to structure studies with the New

Mexico Petroleum Recovery Research Center or RPSEA who are the entities often commissioned for such 

work.

whitepaper referenced a	 study	 commissioned	 by	 the	 Environmental	 Defense	 Fund that	

reviewed	only	22	sources	of	emissions.			IPANM	strongly	contests	the	use	of	this	paper	as	

the	 assumptions	 used	 are	 wildly	 inaccurate.	 	 First,	 the	 average	 $4mcf	 value	 is	 high,	

particularly	for	smaller	operators	who received	much	less	on	average	during	most	of	2012	

and	 201318.	 	 Second,	 the	 base	 assumption	 that	 the	 cost	 of	 flaring	 is	 only	 $3523	 per	 well

ignores	the	true	costs	which,	by	IPANM	member	review,	were	well	in	excess	of	$10,000	per	

well	 because	 of	 the equipment	 rental,	 mileage,	 time and	 personnel	 time	 to	 operate	 the	

equipment.			As	noted	earlier	in	this	comment,	the	small	producer	has	significantly	different	

economics	 than	 major	 companies	 who	 employ	 personnel	 versus	 hiring	 consultants	 or	

contractors	at	market	rate	to	conduct	a	test	or an	emergency	procedure	such	as	a	flare	or	

venting	 during	 liquids	 offloading.	 	 The	 misuse	 of	 the	 cost	 figures	 which	 ICF	 then

extrapolated	 to	 estimate	 savings	 on	 a	 nationwide	 basis	 renders	 the	 EDF	 study	 close	 to	

meaningless	 as	 a	 foundation	 for	 a	 Whitehouse	 methane	 reduction	 strategy.	 	 Clearly,	the	

manner	 in	 which	 the	 EPA researched	 the	 issues	 raised	 in	 the	 whitepapers	 was	 nothing	

more	 than	 a	 ‘data	 dump’	 that	 could	 not	 be	 considered	 an	 adequate	 learning	 process	 to	

establish	 expertise	 on	 these	 very	 complex	 matters.	 IPANM	 contends	 that	 based	 on	 the	

inadequate	 information	 reviewed, that	 the	 EPA	 does	 not	 have	 any	 sort	 of	 a	 ‘robust	

understanding19’ of	 these	 sources	 of	 methane	 thus,	 moving	 forward	 with	 policy	 or	 rule	

promulgation	is	premature at	this	time.

completion of the papers would result in ‘robust technical understanding’ of the issues. IPANM contends that 

in every instance that the studies used and the lack of data does not give EPA regulators the required 

understanding of the issues to establish policy.

In	addition,	 IPANM	would	 urge	 the	 EPA	 to	 review	and	 completely	 understand	the	

information	 included	 in	 the	 National	 emissions	 inventory	 and	 information	 submitted	

pursuant	 to	 the	recently	promulgated	NSPS	SubPart	OOOO	amendments20.		This	data will	

provide	a	large	amount	of	information	about emissions	at	oil	and	natural	gas	facilities but	

experts	 who	 understand	 industry	 must	 study	 and	 understand	 the	 information	 prior	 to	

establishing	policy.	21 NSPS	SubPart	OOOO requires	 federal	air	 standards	 for	new	natural	

gas	 wells	 that	 are	 hydraulically	 fractured,	 along	 with	 requirements	 for	 several	 other	

sources	 of	 volatile	 organic	 compound	 (VOC)	 emissions	 from	 new	 storage	 vessels,	 newly	

installed	compressors,	pneumatic	controllers	and	equipment	leaks	at	natural	gas	facilities.	

Although	 the	 New	 Source	 Performance	 Standards	 directly	 regulate	 VOC	 emissions,	 in	 a	

Government	Accounting	Office	report	issued	May	16,	2014,	the	EPA	reports	that	the	control

against exclusive use of this study, however, since the measurements used were from shale formations only.

Specific	Comments	BY	IPANM	Members	to	April	2014	Whitepaper,	“Oil	and	Natural	Gas	

Sector	liquids	unloading	processes”

General	 Comment	 – The	 oil	 and	 gas	 industry	 does	 not	 vent	 gas	 if	 there	 is	 an	

economic	way	to	capture	and	sell	the	gas.	We	are	in	the	business	of	selling	gas,	so	it	is	not	in	

our	best	interest	to	allow	gas	to	vent	to	the	atmosphere	if	we	can	economically	sell	the	gas.	

5.0	Charge	Questions	for	Reviewers

1. Please	 comment	 on	 the	 national	 estimates	 of	 methane	 emissions	 and	 methane	

emission	factors	for	liquids	unloading	presented	in	this	paper.		

The	emissions	reported	in	the	EPA’s	Greenhouse	Gas	Reporting	Program	for	plunger	

lift	venting	are	significantly	higher	than	actuals	due	to	the	required	calculation	method.	The	

calculation	method	 required	in	 Subpart	W	incorrectly	 assumes	 that	 the	 entire	 volume	 of	

the	tubing	is	vented	every	time	a well	on	plunger	lift	vents	to	atmosphere.	The	plunger	may	

travel	most	of	the	way	up	the	tubing	against	line	pressure,	but	can’t	make	it	all	the	way	to	

																																																							 24 Edwards, M. & Trancik, J., “Climate Change of energy technologies depend on emissions timing”, Nature Clim. 

Change Letter, May 2014. The actual impact of methane from different energy sources is substantially 

different than previously believed using the very simplistic GWP modeling. The MIT researchers advocate the 

use of dynamic modeling that better accounts for the differing radiative efficiencies and atomospheric lifetimes 

of different gases. In essence, the comparison of gases must be dependent on the timing of the emissions. The 

researchers note that while it might be in vogue to tout the disasterous health effects of emissions from coalfired plants as a policy determination to support natural gas plants, three decades from now, the emissions 

advantages of natural gas as compared to coal would be half of the levels claimed in the GWP modeling.

surface	 due	 to	inadequate	 reservoir	 pressure.	Many	 of	 our	 plunger	 wells	 only	 vent	 for	 a	

very	 short	 time	to	 bring	 the	 plunger	 the	 rest	 of	 the	way	 to	 the	 surface.	But	 the	 required	

calculation	method	assumes	 the	entire	 tubing	 volume	was	 vented	whether	it	only	 vented	

for	 15	 seconds	 or	 20	 minutes.	 What	 factors	 influence	 frequency	 and	 duration	 of	 liquids	

unloading (e.g.,	regional	geology)?		Every	well	is	different.	Yes,	a	high	reservoir	pressure	is	

beneficial,	but	there	are	many	other	 factors	that	can	have	an	impact	on	liquids	unloading.	

These	factors	include:	line	pressure,	consistency	of	the	line	pressure,	well	depth,	amount	of	

liquids,	kind	of	liquid,	volume	of	gas,	and	tubing	size.

3. Is	this	only	a	problem	for	wells	further	down	their	decline	curve	or	can	wells	develop	liquids	

loading	problems	relatively	quickly	under	certain	situations?	

Many	new	wells	in	lower	pressure	or	depleted	reservoirs	require	liquids	unloading	

from	the	very	beginning.	Lower	volume	gas	wells	may	require	liquids	unloading	 from	the	

beginning.	 Are	 certain	 wells	 more	 prone	 to	 developing	 liquids	 loading	 problems,	 such	 as	

hydraulically	 fractured	 wells	 versus	 conventional	 wells	 or	 horizontal	 wells	 versus	 vertical	

wells? There	 is	 no	 difference	 in	 liquids	 unloading	 between	 fractured	 wells	 and	 nonfractured	 wells,	 except	 the	 fractured	 wells	 generally	 produce	 at	 a	 higher	 rate	 allowing	

produced	liquids	 to	 be	carried	up	in	 the	gas	 stream.	The	 same	can	 be	 said	 for	horizontal	

wells.	The	higher	production	rates	may	have	enough	velocity	to	carry	produced	liquids	out	

in	 the	 gas	 stream,	 thus	 postponing	 liquids	 loading	 problems	 until	 later	 in	 the	 well’s	 life.	

Once	liquid	unloading	is	required,	horizontal	wells	usually	do	not	use	plunger	lift,	because	

the	plunger	will	not	fall	past	about	65	degrees.	Non	venting	artificial	lift	such	as	rod	pumps,	

electric	submersible	pumps	or	hydraulic	pumps	are	normally	used	on	our	horizontal	wells.

4.	Please	comment	on	the	costs	of	these	technologies.	

If	a	gas	well	will	not	free	flow,	the	liquids	unloading	technology	used	is	based	upon	

the	well’s	parameters	and	economics.	There	are	many	variables,	but	average	costs	for	wells	

in	the	San	Juan	Basin	range	from	$20,000	for	a	plunger	list	and	$120,000	for	a	Rod	Pump	

versus	$170,000	for	an	electric	submersible.

6. Are	there	situations	where	plunger	lifts	have	to	vent	to	the	atmosphere?		

Depending	 on	 the	 well’s	 characteristics	 and	 line	 pressures,	 a	 plunger	 lift	 may	

require	venting	to	the	atmosphere.	It	is	obviously	in	industry’s	best	interest	to	operate	the	

plunger	lift	to	minimize	or	eliminate	this	venting,	but	it	is	not	always	possible.	Low	bottom	

hole	 pressure	 and	 high	 line	 pressure	 is	 not	 a	 good	 combination.	 Our	 operators	 make	

adjustments	 to	 cycle	 times,	 shut	 in	 times,	 etc.	 attempting	 to	 maximize	 production	 and	

eliminate	 or	 reduce	 any	 venting	 to	 the	 atmosphere,	 but	 there	 are	 situations	 that	 require	

venting.	

9. Comment	on	the	pros	and	cons	of	installing	a	“smart”	automation	system	as	part	of	a	

plunger	lift	system.	

A	 “smart”	automation	 system	is	not	a	 cure-all	 on	 venting	if	 the	 reservoir	 does	not	

have	 the	 pressure	 to	 bring	 up	 the	 plunger/water	against	line	 pressure,	 plus	 they	are not	

economic	on	all	wells.	

13. Why	do	owners	and	operators	of	wells	choose	to	perform	blowdowns	instead	of	employing	

one	of	these	techniques?

Many	times	periodically	blowing	down	a	well	to	remove	liquids	is	the	only	economic	

way	to	produce	a	low	volume	well.	These	wells	would	not	economically	support	the	costs	

to	 install	 and	 maintain	 other	 forms	 of	 artificial	 lift.	 If	 not	 blowndown,	 the	 well	 would
