Legislation to Approve the U.S.-Mexico Transboundary Hydrocarbons Agreement

Summary
The offshore areas of the Gulf of Mexico provide a setting for domestic and international energy
production, U.S. military training and border operations, trade and commerce, fishing, tourism,
and recreation. These governmental and commercial activities depend on healthy and productive
marine and coastal areas for a range of economic and social benefits. Consequences of hurricanes
and oil spills demonstrate that offshore areas in the Gulf of Mexico are governed by a number of
interrelated legal regimes, including treaties and international, federal, and state laws.
A key congressional interest has been the federal role in managing energy resources in deepwater
areas of the Gulf of Mexico, particularly in waters beyond the U.S. exclusive economic zone
(EEZ, more than 200 miles from shore). In 2012, the United States and Mexico signed an
agreement known as the U.S.-Mexico Transboundary Hydrocarbons Agreement (the Agreement).
This Agreement could mark the start of an energy partnership in an area of international waters
that the U.S. Department of the Interior’s (DOI’s) Bureau of Ocean Energy Management (BOEM)
estimates to contain as much as 172 million barrels of oil and 304 billion cubic feet of natural gas.
The main purposes of the partnership between these two countries would be to lift a moratorium
and to jointly develop reservoirs of oil and natural gas, referred to as “transboundary resources,”
that exist in areas straddling the marine border of both countries. The Agreement stems from a
series of bilateral treaties originating in the 1970s. Like other diplomatic measures, for the
Agreement to take effect, it must be placed before each country’s national lawmakers for review.
Both countries have completed review and accepted the Agreement. Further legislative attention
is anticipated as part of implementing the Agreement.
In the United States, implementing legislation involves the two main commitments of the
Agreement. First, under the Agreement, the two countries take steps to establish a framework for
jointly developing 1.5 million acres along a 550-mile border. Diplomats on both sides of the
border claim that this framework would achieve a mutual goal of greater options for energy
production to help gain greater energy independence for both countries. A concurrent
commitment is the cessation of the treaty-based moratorium on oil and gas development,
encompassing 158,584 acres along a 135-mile portion of the border. Original treaty provisions
recognized the ban until 2014.
Congress approved the Agreement during the first session of the 113th Congress (P.L. 113-67, the
Bipartisan Budget Act of 2013). Prior to enactment, both chambers had also passed legislation
approving the Agreement (H.R. 1613, S. 812). Arguably, implementing the Agreement faces
hurdles in both countries. In the United States, among other hurdles is the statutory mandate to
present an implementation plan to Congress. In Mexico, implementation poses various other
constitutional and regulatory challenges, the pace of which has not been determined.
This report analyzes relevant legislative initiatives (S. 812 and H.R. 1613) and other legislative
action surrounding Congress’s approval of the Agreement (P.L. 113-67). A related report, CRS
Report R43606, U.S.-Mexico Transboundary Hydrocarbons Agreement: Background and Issues
for Congress, provides a description and basic analysis of the Agreement and related diplomatic
activities, including diplomatic perspectives on Congress’s approval of the Agreement.

Legislation to Approve the U.S.-Mexico Transboundary Hydrocarbons Agreement

Introduction
Since the 1970s, prompted by high fuel prices and a mutual interest in greater energy security, the
United States and Mexico have agreed to a series of bilateral treaties defining territorial claims
and laying the groundwork for future offshore oil and gas development partnerships. 1 These
treaties and other diplomatic activities are helping to define each nation’s stake in oil and gas
resources in ocean areas in the western Gulf of Mexico beyond each country’s 200-mile exclusive
economic zone (EEZ).2
A prominent component of these treaties has been an offshore moratorium on oil and gas
development covering a 158,584-acre area within a larger transboundary area encompassing 1.5
million acres.3 The stated purpose of this moratorium is to allow time for both countries to form a
partnership for jointly developing transboundary oil and gas resources beyond each country’s
EEZ.
The United States and Mexico are moving to form a partnership to jointly manage areas for
offshore drilling operations. This entails lifting the temporary moratorium and replacing it with a
framework for a joint development scenario.4 The United States and Mexico are not alone in
seeking this type of energy partnership. Around the world, nations claiming ocean areas beyond
established national borders are forming similar partnerships to cope with challenges associated
with managing offshore areas for developing oil and gas resources.5 The global race for ocean
energy resources is among other contributors to legislative interest in diplomatic talks between
the United States and Mexico. These talks concluded in 2012 with both countries signing the
U.S.-Mexico Transboundary Hydrocarbons Agreement (the Agreement).6
With passage of the Bipartisan Budget Act of 2013 (P.L. 113-67), the U.S. Congress approved the
Agreement and set in motion options for U.S. implementation. 7 Determining implementation

1 U.S. leases and various permitting and financing applications typically include a government plat indicating the
precise location of a lease and cartographic information regarding the various geographical elements of the proposed
well, the location of drilling equipment, among other things. Thus, a plat must exist indicating these locations along
with information regarding the various spatial elements of any proposed drilling operations. 30 C.F.R. §550.411; 30
C.F.R. §551.
2 Treaty to Resolve the International Boundary, signed on November 23, 1970; Treaty on Maritime Boundaries
between the United Mexican States and the United States of America, signed on May 4, 1978; and Treaty between the
Government of the United Mexican States and the Government of the United States of America on the Continental
Shelf, signed on June 9, 2000.

Development: Legal Framework, by Adam Vann.
4 Under the U.S.-Mexico Transboundary Hydrocarbons Agreement, both countries might proceed with deepwater
development via “unitization,” a model commonly used for federally regulated drilling in the U.S. Gulf of Mexico. A
framework (specifically to support unitization as a model for development, which is explained in a basic fashion in the
next section) is widely recognized as necessary for offshore exploration and production to occur.

options consistent with the Agreement is the responsibility of the Bureau of Safety and
Environmental Enforcement (BSEE), an agency within the Department of the Interior (DOI ),
among other federal agencies.8
Recent Developments
Controversy that surrounded U.S. review of the Agreement highlights a persistent tension
between proponents of ocean oil and gas drilling seeking to accelerate production of domestic
energy supplies and those who support maintaining the moratorium in order to provide time for
safety and environmental issues to be more fully addressed.9
Recent legislative activities (discussed in greater detail below) have occurred within a statutory
framework for managing areas beyond the U.S. exclusive economic zone (EEZ)10 involving
shared powers found within the U.S. Department of State and the U.S. Department of the
Interior’s (DOI).11 Consistent with the objectives of two programs (the Five-Year Outer
Continental Shelf Oil and Gas Leasing Program12 and the Offshore Renewable Energy
Program13), DOI manages more than 8,000 domestic leases organized in a grid system that was
established at the start of the program in 1953.14

the Bipartisan Budget Act of 2013 and the Pathway for SGR Reform Act of 2013.Prior to passage of H.J.Res. 59, U.S.
review of the Agreement included House and Senate passage of legislation to approve and implement the Agreement.
On June 27, 2013, the House passed H.R. 1613 (H.Rept. 113-101); and on October 14, 2013, the Senate passed S. 812
by unanimous consent. While the Agreement awaited a U.S. determination, the moratorium on oil, gas, and mineral
activities that was established in a previous treaty remained in place.
8 Bureau of Safety and Environmental Enforcement (BSEE, pronounced “Bessy”), is responsible for oversight and
enforcement, field operations, inspections, workforce safety, and decommissioning. BSEE promulgated new safety
rules in 2010 and 2011 in the wake of the Deepwater Horizon oil spill. These new safety requirements are anticipated
to be fully operational in 2014. For analysis of these topics as they relate to recent reforms, see CRS Report R42942,
Deepwater Horizon Oil Spill: Recent Activities and Ongoing Developments, by Jonathan L. Ramseur and Curry L.
Hagerty. For more information about management changes within the DOI bureaus responsible for offshore energy
production, see GAO-13-283 High-Risk Series (February 14, 2013). This report outlines management challenges
related to drilling programs. It is updated every two years, at the start of each new Congress. See also Department of
the Interior: Major Management Challenges, GAO-11-42T (March 1, 2011).
9 The main tension expressed by supporters and opponents of H.R. 1613, as reported by the House Committee on
Natural Resources, involved provisions to exempt actions taken by public companies in accordance with the
transboundary hydrocarbon agreement from requirements under Section 1504 of the Dodd-Frank Act and the Securities
and Exchange Commission’s Natural Resource Extraction Disclosure Rule. For arguments in favor of these provisions,
see H.Rept. 113-101, and for counterarguments, see “Statement of Administration Policy on H.R. 1613” (June 25,
2013), at http://www.whitehouse.gov/sites/default/files/omb/legislative/sap/113/saphr1613r_20130625.pdf.
10 The U.S. EEZ generally includes territory 200 nautical miles seaward of state waters. See Presidential Proclamation
No. 5030, 48 Federal Register 10605 (March 14, 1983).
11 Bureau of Ocean Energy Management (BOEM, rhymes with “Rome”) is tasked with offshore leasing administration,
including developing maps, completing scientific and economic analyses, and issuing leases. BOEM also participates
in some international relations missions regarding U.S. ocean energy resources.
12 See Five-Year OCS Oil and Gas Leasing Program 2012-2017. This program was approved on August 27, 2012, and
is anticipated to be in place through 2017. Each program is mandated by the Outer Continental Shelf Lands Act (43
U.S.C. §1344) to be “a schedule of proposed lease sales indicating, as precisely as possible, the size, timing, and
location of leasing activity which ... will best meet national energy needs.”

DOI estimates future revenues of $50 million in 2014 from energy activities projected to take
place in the transboundary area.15 U.S. ocean energy production currently accounts for 26% of
domestic oil production and about 16% of domestic natural gas production. While most offshore
acreage is found in the Alaska region (approximately 1.03 billion acres of a total of 1.7 billion
acres), oil and gas leases are located mainly in the Gulf of Mexico (89% of the federally regulated
offshore energy activity is concentrated in an area accounting for about 2% of U.S. waters).16
Review of the Agreement17
The Agreement is widely recognized as an initial step toward a joint development scenario
involving three U.S.-Mexico commitments: (1) eliminating the moratorium in waters beyond
their respective exclusive economic zones (EEZs); (2) studying the transboundary areas
(exchanging geological information); and (3) potentially deploying joint oil and gas operations
associated with developing transboundary reservoirs.18
The Agreement consists of seven chapters and 27 articles. Provisions attracting particular
attention include Chapter 3 (Articles 10-13: establishing a joint development scenario) and
Chapter 7 (Article 24: terminating the current moratorium).
Following a statement of “General Principles” including the scope,19 definitions,20 jurisdiction21
and permissible activities,22 the Agreement establishes a process for jointly determining the

15 See DOI FY2014 Congressional Budget Justification, Bureau of Ocean Energy Management (BOEM), p. 12. DOI
bases this statement on assumptions about bonus payments and other predicted revenue streams for rentals and taxes
deriving from operations in the transboundary area cited in the Agreement. Estimates of federal budget effects vary
widely. For example, a recent estimate by the Congressional Budget Office (CBO) provided as part of analysis of a
specific bill to implement the Agreement (H.R. 1613) concluded that approving and implementing the Agreement in
that instance would increase federal receipts by $25 million from 2014 through 2023.
16 In addition to generating domestic energy supplies in these areas, federally regulated offshore energy projects are
recognized as generating significant public receipts, including approximately $6.9 billion in 2012. Statistics about
annual energy supplies and annual receipts from bonus bids, rentals, and royalties are published through numerous
sources. The statistics in this report are derived from the Office of Natural Resources Revenue within DOI, available at
http://www.ONRR.gov. For ocean energy revenue statistics, see http://www.ONRR.gov. FY2012 federal offshore
reported revenues were $6.9 billion; FY2011, $6.5 billion; and FY2010, $5.3 billion.
17 This section does not provide a comprehensive legal examination of the Agreement’s contents and does not offer an
in-depth analysis of U.S. interests in various provisions. A variety of topics addressed in other CRS reports analyze
policy perspectives surrounding U.S. interests in the Agreement: peacetime military engagement; fisheries
enforcement, search and rescue, drug interdiction, trade, investment and marine pollution law enforcement. These
topics are distinct in many ways from topics surrounding U.S. interests in managing ocean energy resources in U.S.
waters. For more information on these aspects of U.S.-Mexico relations, see CRS Report R42917, Mexico: Background
and U.S. Relations, by Clare Ribando Seelke; CRS Report R41349, U.S.-Mexican Security Cooperation: The Mérida
Initiative and Beyond, by Clare Ribando Seelke and Kristin Finklea; and CRS Report R42965, NAFTA at 20: Overview
and Trade Effects, by M. Angeles Villarreal and Ian F. Fergusson.
18 Joint commitments listed in the Agreement involve goals for the safe and equitable exploitation of transboundary
reservoirs. These commitments are intended to unfold over many years through further negotiations aimed at
facilitating more specific approaches to such issues as standards for operations and environmental review. Until the
Agreement is accepted, the timeline for implementation remains unclear. Numerous federal regulators might be
involved in activities covered by the Agreement. Operational safety and revenue obligations related to any future oil
and gas leases have already been delegated to BOEM. See CRS Report R42599, Department of the Interior (DOI)
Reorganization of Ocean Energy Programs, by Curry L. Hagerty.
19 Article 1 provides that the Agreement applies to areas extending “across the Delimitation Line” This line begins
beyond 9 nautical miles from the coastline of Texas and ends 550 miles to the east, at the point to the west of the
Eastern Gap.

existence of transboundary reservoirs.23 These guidelines offer basic details for a “Unitization
Agreement;”24 for joint management principles;25 and for production allocations.26 As a
requirement for steps taken by unit operators27 and any future fiscal terms related to exploiting oil
and natural gas reservoirs in specific areas,28the Agreement states basic guidelines for terminating
the treaty-based moratorium on hydrocarbon development.29
Possible By-Products of Implementing the Agreement30
It is too early to speculate on all the possible scenarios following U.S. approval of the Agreement.
Prior to both countries approving the Agreement, diplomats in the United States and Mexico
described possible implications of implementing the Agreement as follows:
• The United States is anticipated to complete an implementation plan as a first
step toward jointly managing the transboundary area.
• Cessation of the diplomatic moratorium on oil exploration and production is
anticipated 60 days after the exchange of U.S. diplomatic notes with Mexico.
BOEM reports this exchange is expected sometime after May 17, 2014.31
• A cooperative process for managing the maritime boundary region would begin.

(...continued)
20 Article 2 provides definitions for 24 terms, starting with “Confidential Data” and ending with “Unit Operating
Agreement.”
21 Article 3 states that nothing in the Agreement “shall be interpreted as affecting the sovereign rights and the
jurisdiction which each Party has under international law ...”
22 Article 4 establishes requirements for consultations “on exploration and exploitation activities” carried out within
certain areas surrounding the Delimitation Line.
23 Article 5 outlines a multi-step process for reaching a determination on the existence of a Transboundary Reservoir.
This determination entails deadlines for consultations and submissions to the “Joint Commission” as defined elsewhere
in the Agreement.
24 Article 6 details the components of a Unitization Agreement, including requirements to measure production;
procedures for ensuring accurate payments of royalties and other proceeds; and safety and environmental measures to
be taken under the national laws of each party.
25 Article 7 addresses management guidelines prior to the formation of a transboundary unit.
26 Articles 8 and 9 provide for determining and redetermining allocation of production.
27 Article 10 reads as follows: “The Executive Agencies shall ensure that a unit operator for a Transboundary Unit is
designated by agreement between the Licensees. The designation or change of the unit operator shall be subject to the
approval of the Executive Agencies. The unit operator will act on behalf of the Licensees.”
28 Article 13 provides the following: “Income arising from the Exploitation of Transboundary Reservoirs shall be taxed
in accordance with the legislation of the United Mexican States and the United States of America respectively, as well
as the Convention between the Government of the United States of America and the Government of the United
Mexican States for the Avoidance of Double Taxation and the Prevention of Fiscal Evasion with respect to Taxes on
Income and Capital, signed on September 18th, 1992, as amended (and as may be amended in the future), or any
Convention superseding that Convention as the Parties may enter into in the future.”
29 Article 24 reads as follows: “Upon entry into force of this Agreement, the period of any moratorium on the
authorization or permitting of petroleum or natural gas drilling or exploration of the continental shelf within the
boundary “Area” as established by Article 4, paragraph 1, of the 2000 Treaty on the Continental Shelf and extended by
any subsequent exchanges of notes shall be terminated.”

Legislation to Approve the U.S.-Mexico Transboundary Hydrocarbons Agreement

• It would be possible for commercial activities to occur, with options for
companies to voluntarily enter into unitization arrangements. In the event such an
arrangement is not achieved, the Agreement also establishes options by which
companies might develop potential resources on each side of the border.
• Joint inspection teams addressing compliance with applicable laws and
regulations would be activated by both governments to review operational plans
relevant to transboundary reservoirs.32
Possible impacts on activities in the Gulf of Mexico or, from a broader perspective, on the
national ocean energy portfolio remain a matter of conjecture.33 For example, as part of
estimating fiscal impacts, many in Congress have turned to the Congressional Budget Office
(CBO) score for H.R. 1613.34 On May 17, 2013, CBO estimated that “enacting H.R. 1613 would
increase offsetting receipts from offshore lease sales by $25 million from 2014 through 2023.” As
part of this analysis, CBO assumes, first, that approving the Agreement would allow DOI to offer
leases for acreage which is currently under moratorium and, second, that approving the
Agreement would increase values of other leased tracts in the nearby area.35
Related Legislation
The Administration and some in Congress had advocated for swift U.S. acceptance of the
Agreement. With a backdrop of oversight hearings in the House and Senate during the 113th
Congress, lawmakers continue examining domestic energy production options.36 Others
expressed skepticism that the Agreement is an optimal approach to expand the U.S. ocean energy
portfolio in the Gulf of Mexico. The Bipartisan Budget Act of 2013 (P.L. 113-67) approved the
Agreement, and two other legislative initiatives (H.R. 1613 and S. 812) were considered as part
of U.S. review of the Agreement. To date, attention to this Agreement has involved differing
policy options, with the common theme being to replace the current moratorium on oil and gas
development with the start of a joint development plan.

32 See joint statement adopted by Presidents Obama and Calderon, Washington, DC, May 19, 2010.
33 Concurrent with regulating operations in the Gulf of Mexico, DOI is assessing energy resource potential off the coast
of the Mid- and South Atlantic and off the coasts of California and Alaska, including in the Chukchi and Beaufort Seas.
For a comprehensive statement of current federal policies toward offshore oil and gas development, see 77 Federal
Register 40080 (July 6, 2012).
34 For a full CBO report on H.R. 1613, see http://www.cbo.gov/sites/default/files/cbofiles/attachments/hr1613.pdf.

and Gas Leasing Program for 2012–2017, 77 Federal Register 40080 (July 6, 2012).
36 The hearings listed below and elsewhere in this report reflect two visions: seeing the need to grant access to some
areas to enhance energy production and—as a counterbalance—seeing the need to defer access to some areas to protect
people and the environment from risk. On March 14, 2013, the House Committee on Foreign Affairs, Subcommittee on
the Western Hemisphere held a hearing entitled U.S. Energy Security: Enhancing Partnerships with Mexico
and Canada. On April 25, 2013, the House Committee on Natural Resources, Subcommittee on Energy and Mineral
Resources, held a legislative and oversight hearing entitled U.S.-Mexico Transboundary Hydrocarbon Agreement and
Steps Needed for Implementation.

Legislation to Approve the U.S.-Mexico Transboundary Hydrocarbons Agreement

P.L. 113-67, the Bipartisan Budget Act of 2013
P.L. 113-67, the Bipartisan Budget Act of 2013, was signed by the President on December 26,
2013. P.L. 113-67 includes provisions that, among other provisions, accepts the Agreement and
requires DOI (after not more than 180 days) to submit an implementation plan to Congress,
presumably signaling implementation will be managed by DOI.
In contrast to other legislation to approve the Agreement (discussed below), P.L. 113-67 amends
the Outer Continental Shelf Lands Act to require a DOI implementation plan consistent with the
following: (1) approving unitization agreements;37 (2) sharing certain information;38 (3) acting in
a manner consistent with various determinations defined under the Agreement;39 and, (4) detailing
inspection and stop work criteria.40 P.L. 113-67 differs from other relevant legislation considered
by Congress (and discussed below) in the following respects: (1) no hearing record exists to offer
insights about legislative dialogue related to approving the Agreement, (2) the enacted provisions
amend the Outer Continental Shelf Lands Act (OCSLA, 43 U.S.C. 1331 et seq.), empowering the
Secretary of the Interior to implement the Agreement but only after DOI submits an
implementation plan to Congress; and (3) P.L. 113-67 is silent on reporting requirements found
within the Securities Exchange Act of 1934.41
H.R. 1613
H.R. 1613, “Outer Continental Shelf Transboundary Hydrocarbon Agreements Authorization
Act,” was considered and passed by the House on June 27, 2013.42 This legislation would
establish guidelines and procedures for implementing the Agreement; and among other measures,
would provide for legislative review of any future agreements governing that area. The bill would
amend the Outer Continental Shelf Lands Act (OCSLA, 43 U.S.C. 1331 et seq.) to implement the
Agreement by providing new powers to the Secretary of the Interior for approving unitization
agreements.43

37 Article 6 of the Agreement details the components of a unitization agreement, including requirements to measure
production; procedures for ensuring accurate payments of royalties and other proceeds; and safety and environmental
measures to be taken under the national laws of each party.
38 Article 2 of the Agreement defines 24 terms, including “Confidential Data.”
39 Article 5 of the Agreement outlines a multi-step process for reaching determinations on the existence of a
transboundary reservoir. This determination entails deadlines for consultations and submissions to the “Joint
Commission” as defined elsewhere in the Agreement.
40 Articles 18 and 19 of the Agreement generally reference “applicable national law” as a basis of joint inspections in
the area.
41 Securities Exchange Act of 1934, 157 U.S.C. 78m(q).This topic was a component of the House bill (H.R. 1613)
discussed in the next section.
42 To help understand the role of the House of Representatives with respect to review of this Agreement, it is important
to clarify that the Agreement has not been submitted to the Senate as a treaty. Under the U.S. system, a legally binding
international agreement can take different forms. Unlike agreements taking the form of a treaty (that would enter into
force if approved by a two-thirds majority of the Senate and subsequently ratified by the President), this Agreement
was negotiated and signed by the executive branch as a non-treaty. In the case of a non-treaty, to be legally binding, it
must either be authorized by a statute passed by Congress (“congressional executive agreements”) or a prior treaty
approved by the Senate, except when it concerns matters falling under the exclusive constitutional authority of the
President (“sole executive agreements”). For further discussion, see CRS Report RL32528, International Law and
Agreements: Their Effect upon U.S. Law, by Michael John Garcia.

Legislation to Approve the U.S.-Mexico Transboundary Hydrocarbons Agreement

By adding a new section to the end of the OCSLA (“Section 32”), the bill would authorize the
Secretary to implement the Agreement with Mexico by completing the following steps:
• submitting the Agreement to the Speaker of the House; the Majority Leader of
the Senate; the Chairs of the House Committee on Natural Resources and the
Senate Committee on Energy and Natural Resources;
• including in the submission (1) legislation relevant to implementation,
(2) economic analysis of impacts of the Agreement on domestic production of
offshore oil and gas resources, (3) a description of regulations expected to be
issued to implement the Agreement, and (4) provisions adopting unitization as
the approach to developing the area.44
Furthermore, H.R. 1613 would exempt U.S. firms from certain reporting requirements of the
Securities Exchange Act of 1934.45 Currently, publicly traded companies are required to disclose
certain information regarding business dealings related to extractive operations to investors
through filings with the Securities and Exchange Commission (SEC). Section 1504 of the Dodd-
Frank Wall Street Reform and Consumer Protection Act of 2010 (P.L. 111-203) amended the
Securities Exchange Act of 1934 by expanding certain required public company disclosures.46
When applied to the commercial development of oil, natural gas, or minerals, the act requires the
disclosure of certain payments made to the federal government or foreign governments by public
companies required to file annual reports with the SEC. The provision in H.R. 1613 entitled
“Exemption from Resources Extraction” provides that actions taken by such a public company
pertaining to any transboundary hydrocarbon agreement shall be exempt from such disclosure
requirements.47
S. 81248
This bill would authorize the Secretary of the Interior to implement the Agreement in a manner
consistent with legislative provisions proposed by the Administration and referred to in the
Administration’s 2014 budget request.49 Specifically, under the legislative proposal referred to in

Committee on Financial Services. On June 6, 2013, the Committees on Foreign Affairs and Financial Services
discharged the bill.
44 In addition, H.R. 1613 offers placeholders for implementing Agreements with four other countries: Canada, Russia,
the Bahamas, and Bermuda. Although placeholders are sometimes included in bills that are introduced, they have rarely
been enacted as law.

Summary, coordinated by Baird Webel.
47 In general, the American Petroleum Institute (API) and other business groups have resisted implementation of

publicly traded U.S. oil and gas companies to report information about projects that potentially could benefit their
overseas national oil companies.

Legislation to Approve the U.S.-Mexico Transboundary Hydrocarbons Agreement

the budget request and under S. 812, the Secretary of the Interior would be provided with new
authorities to approve unitization agreements and related arrangements within certain guidelines.
This approach contrasts with H.R. 1613 in several respects.
A key distinction between the Senate and House bills is the additional provisions in the House
bill, particularly regarding disclosure requirements for investment information pursuant to
U.S. Securities and Exchange Commission (SEC) rules. Specifically, the House bill clarifies the
application of Section 13(q) of the Securities Exchange Act of 193450 in matters related to joint
development projects in the transboundary area. In contrast, S. 812 is silent on this point, not
addressing the treatment of U.S. firms and SEC obligations.
Looking Ahead
Dialogue surrounding U.S. initiatives to grant (or defer) offshore oil and gas drilling rights
beyond the U.S. EEZ will likely continue.51 Beyond resource management, other issues and
national interests (diplomatic, military, trade) are part of engaging Mexico in areas beyond the
U.S. EEZ.52 Related issues include how to handle public receipts (royalties and other gains), if
any, anticipated from jointly managed ocean energy projects and how to cope with oil spill risks
and other risks associated with a joint development scenario.
Legislative action in the House and Senate highlighted differences in how best to implement the
Agreement. In the House, debate underscored a policy divide that frequently accompanies
legislative review of ocean energy initiatives.53 Arguably, two main legislative approaches exist:
one focusing on the benefits of maintaining a moratorium on ocean drilling and the other focusing
on gains anticipated from options to generate new energy supplies and public revenues. Some
commentary highlights external factors associated with U.S.-Mexico relations.54 However, most
arguments are reminiscent of the historic choices faced by U.S. lawmakers in the past about
whether, when and where to allow ocean drilling and how to monitor development scenarios
where permissible.

51 The offshore drilling debate is a combination of several discrete debates about oil and gas leasing activity in federal
and international waters. Congress addresses multiple issues related to access (state-federal consultations about state
revenue sharing, adequacy of environmental reviews, timetables for drilling permitting, operational safety, federal
receipts and disbursements to federal programs, research).

Legislation to Approve the U.S.-Mexico Transboundary Hydrocarbons Agreement

Appendix. Summary of Congressional Hearings
Legislation accepting the Agreement and formalizing DOI authority to implement the
Transboundary Hydrocarbons Agreement passed on December 18, 2013, as part of P.L. 113-67,
the Bipartisan Budget Act of 2013.55 There is not a robust legislative hearing record for U.S.
acceptance of this Agreement. Legislative records of deliberations surrounding enacted legislation
afford few details about lawmaker points of view on the Agreement.
Prior to enactment, both chambers had passed separate bills: S. 812 and H.R. 1613. Lawmakers
favoring these bills expressed support for a general goal of approving the Agreement but there
was little to indicate consensus on other aspects of the legislation. For example, hearings
conducted in the House were conducted prior to lawmakers introducing relevant bills.56 At these
hearings, absent the opportunity to parse introduced legislation, witnesses mainly offered general
statements relevant to the Agreement. As a result, House hearings lacked the more precise
legislative analysis and stakeholder discussion that can come from review directly related to
pending legislation.57 Objections to specific provisions in the House legislation were expressed by
those in Congress opposed to eliminating certain Securities and Exchange Commission (SEC)
disclosure requirements found only in H.R. 1613, as reported by the House Committee on Natural
Resources. 58
Furthermore, in the Senate, the single hearing on this Agreement allowed for an examination of
specific legislative provisions relevant to U.S. interests in transboundary hydrocarbon reservoirs
(S. 812), however, the context for parsing the legislation was rather limited due to the federal
government shutdown in effect at that time. 59
House Committee on Foreign Affairs
On March 14, 2013, the House Committee on Foreign Affairs, Subcommittee on the Western
Hemisphere held a hearing entitled U.S. Energy Security: Enhancing Partnerships with Mexico
and Canada.60 At the hearing the four witnesses representing academia and private sector firms61

55 H.J.Res. 59 was passed by the House of Representatives on December 12, 2013. It was passed by the Senate on
December 18, 2013. See also CRS Report R43068, The Federal Budget: Issues for FY2014 and Beyond, by Mindy R.
Levit.
56 Both hearings in the House are discussed below; all relevant legislation is discussed in the section above entitled
“Legislative Interests.”
57 This Agreement has been characterized as very technical in nature, as compared to earlier U.S.-Mexico compacts
related to governance of acreage in western Gulf of Mexico. For a discussion detailing the technical aspects of the
Agreement see U.S.-Mexico Agreement on Transboundary Hydrocarbon Reservoirs in the Gulf of Mexico: A Blueprint
for Progress or a Recipe for Conflict? by Jorge A Vargas, (San Diego International Law Journal Fall, 2012).
58 As noted in the Statement of Administration Policy on H.R. 1613, the Administration supports implementing
legislation, without the inclusion of provisions such as those relating to Section 1504 of the Dodd-Frank Act that
arguably would dilute U.S. efforts to increase transparency and accountability. These provisions would exempt actions
taken by public companies from requirements under a section of the Securities and Exchange Commission’s Natural
Resource Extraction Disclosure Rule. It is widely recognized that, among other provisions found in H.R. 1613, these
disclosure provisions involve issues extraneous to approving the Agreement.
59 Lawmaker and witness participation as well as press attendance at the hearing were notably limited by conditions not
found when the government is not shutdown. CRS Report RL34680, Shutdown of the Federal Government: Causes,
Processes, and Effects, coordinated by Clinton T. Brass.

Legislation to Approve the U.S.-Mexico Transboundary Hydrocarbons Agreement

claimed that U.S. approval of the Agreement would impact U.S. and Mexican interests through
one or more of the following considerations:
• “Approving the treaty will create new levels of legal certainty for U.S.
and Mexican firms operating in the Gulf border regions, encouraging them to
engage in the risk-taking required to produce oil from deep waters.”62
• “Swift ratification of the Transboundary Hydrocarbon Agreement is important to
our nation’s energy security and long-term economic growth.”63
• “The current focus on hydrocarbon reform in Mexico also means that extended
U.S. inaction on the Transboundary Hydrocarbons Agreement will be noticed,
with potentially negative consequences for the broader bilateral relationship.”64
House Committee on Natural Resources
On April 25, 2013, the House Committee on Natural Resources, Subcommittee on Energy and
Mineral Resources held a legislative and oversight hearing entitled U.S.-Mexico Transboundary
Hydrocarbon Agreement and Steps Needed for Implementation.65 At this hearing, six witnesses
representing federal agencies, private firms, academia, and an internationally recognized
environmental organization offered perspectives on U.S. involvement in the Agreement.66 With
one exception, witnesses voiced support for the Agreement and draft legislation, by claiming that
U.S. acceptance of the Agreement offered greater legal certainty for U.S. energy interests in the
Gulf of Mexico. The one exception was Mr. Manuel, Sierra Club, arguing that the Agreement was
not needed due to the backlog of U.S. leases already in effect in the Gulf of Mexico.67 Witnesses
asserted varying perspectives on the Agreement, based on one or more of the following
considerations:
• The Agreement permits, for the first time, firms on the U.S. side of the border to
cooperate with Mexico’s national oil company, Petróleos Mexicanos (PEMEX),
on joint exploration and development projects.68

Legislation to Approve the U.S.-Mexico Transboundary Hydrocarbons Agreement

• The Agreement allows more numerous options for U.S. oil and natural gas
companies to invest in and to operate in the Gulf of Mexico, creating jobs and
enhancing U.S. energy security.69
• Lacking specifics about safety and environmental protection, it remains unclear
whether the Agreement is compatible with U.S. interests in fishing and tourism in
the Gulf of Mexico.70
Of the witnesses testifying in favor of legislative review and acceptance of the Agreement, each
cited clarifying U.S.-Mexico relations with respect to governing the transboundary area was
needed for safe and responsible energy development to commence. In contrast to the testimony of
these witnesses, the Sierra Club witness expressed skepticism that swift U.S. acceptance was
needed “given that the oil and gas industry is sitting on a large number of inactive leases in
federal waters, proving accelerated leasing in the Gulf of Mexico to be unnecessary.”71
Following these hearings, legislation (S. 812, H.R. 1613) was introduced in both chambers on
April 25, 2013. This legislation would approve and implement the Agreement taking slightly
differing approaches.72
Senate Committee on Energy and Natural Resources
On October 1, 2013, the Senate Committee on Energy and Natural Resources held a legislative
hearing on S. 812 and H.R. 1613, as part of examining the proper federal management role
relevant to transboundary hydrocarbon reservoirs, and for other purposes. Government
witnesses73 offered testimony consistent with support for implementing the Agreement. Private
sector witnesses offered testimony expressing opposing views: industry supporting the
implementing legislation and environmental groups expressing objections.74 The following
highlights describe hearing testimony:
• Without the Agreement, firms on both sides of the border will likely not explore and
develop deepwater projects of interest to both countries.75

and Tommy P. Beaudreau, Acting Assistant Secretary, Land and Minerals Management, DOI.
74 Ms. Jacqueline Savitz, Vice President, U.S. Oceans, Oceana expressed opposition to both bills; Mr. Erik Milito,
Director, Upstream and Industry Operations, expressed American Petroleum Institute support for the legislation.
75 This point was made by Mr. Beaudreau (DOI) and Ambassador Pascual (DOS) and Mr. Milito. For the complete
written testimony of these witnesses see http://www.energy.senate.gov/public/index.cfm/2013/10/full-committee-

Legislation to Approve the U.S.-Mexico Transboundary Hydrocarbons Agreement

• The Agreement allows for more legal certainty for all parties with a stake in planning
offshore development scenarios. Many perceive this added certainty as creating a more
favorable business atmosphere for U.S. oil and natural gas companies seeking to finance
operations in the Gulf of Mexico.76
• Lacking detailed provisions related to safety and environmental protection in the
Agreement, lifting the current moratorium is premature and raises concerns about
pollution events including increased Green House Gas (GHG) emissions and oil spills
that could jeopardize U.S. fishing, tourism and other interests in the Gulf of Mexico and
elsewhere.77
The timing of this hearing and public admission to the hearing were affected by the Senate
experiencing the first day of the federal government shutdown. After this hearing the Senate
Committee on Energy and Natural Resources discharged S. 812 by unanimous consent. On
October 12, 2013, the Senate passed S. 812, without amendment, by unanimous consent.
