I. Background
This interim final rule promulgated
for the prevention of waste and
conservation of natural resources of the
Outer Continental Shelf, establishes
regulations based on certain
recommendations in the May 27, 2010,
report from the Secretary of the Interior
to the President entitled, ‘‘Increased
Safety Measures for Energy
Development on the Outer Continental
Shelf’’ (Safety Measures Report). The
President directed that the Department
of the Interior (DOI) develop this report
as a result of the Deepwater Horizon
event on April 20, 2010. This event,
which involved a blowout of the BP
PO 00000
Frm 00002
Fmt 4701
Sfmt 4700
Macondo well and an explosion on the
Transocean Deepwater Horizon mobile
offshore drilling unit (MODU), resulted
in the deaths of 11 workers, an oil spill
of national significance, and the sinking
of the Deepwater Horizon MODU. On
June 2, 2010, the Secretary of the
Interior directed the Bureau of Ocean
Energy Management, Regulation and
Enforcement (BOEMRE) (formerly the
Minerals Management Service) to adopt
the recommendations contained in the
Safety Measures Report and to
implement them as soon as possible.
The Safety Measures Report
recommended a series of steps to
improve the safety of offshore oil and
gas drilling operations in Federal
waters. It outlined a number of specific
measures designed to ensure sufficient
redundancy in blowout preventers
(BOPs), promote well integrity, enhance
well control, and facilitate a culture of
safety through operational and
personnel management.
The Safety Measures Report
recommended that certain measures be
implemented immediately through a
Notice to Lessees and Operators (NTL).
It identified other measures as being
appropriate to address through an
emergency rulemaking process. The
Safety Measures Report recognized that
other recommendations would require
additional review and refinement
through technical reviews by the DOI,
through information supplied as a result
of the numerous investigations into the
root causes of the Deepwater Horizon
explosion, and through the longer-term
recommendations of DOI strike teams
and inter-agency work groups. The
Safety Measures Report recommended
that these other measures be addressed
through notice and comment
rulemaking, as appropriate.
On June 8, 2010, BOEMRE issued an
NTL addressing those recommendations
identified in the Safety Measures Report
as warranting immediate
implementation (NTL No. 2010–N05—
Increased Safety Measures for Energy
Development on the OCS). This interim
final rule clarifies existing regulatory
requirements that were addressed by
certain portions of NTL No. 2010–N05.
This rule incorporates specific details
included in 2010–N05 by codifying
these into regulations. The rule does not
codify the one-time requirements from
NTL No. 2010–N05, such as the onetime requirement for recertification of
all BOP equipment used in new floating
operations, which will be evaluated and
considered for future rulemakings as
appropriate.
This interim final rule also addresses
measures identified in the Safety
Measures Report as appropriate for
E:\FR\FM\14OCR2.SGM
14OCR2
Federal Register / Vol. 75, No. 198 / Thursday, October 14, 2010 / Rules and Regulations
implementation through emergency
rulemaking, with certain exceptions
discussed later. It also includes other
provisions from the Safety Measures
Report that BOEMRE considers
appropriate for immediate
implementation in this interim final
rule.
As provided for in the Safety
Measures Report, BOEMRE will
continue to review other safety
measures. These include items that may
be appropriate for rulemaking in the
near future, as well as measures that
will require further study, whether
through DOI-led strike teams, interagency workgroups, or other means.

* DOI estimated the cost of a hypothetical spill in the future at $16.3 billion, and also estimated the baseline likelihood of a catastrophic blowout
event and spill occurring, based on historical trends and the number of expected future wells, to be once every 26 years. These estimates are
necessarily uncertain, and are discussed in more detail in the RIA. Combining the baseline likelihood of occurrence with the cost of a hypothetical spill implies that the expected annualized spill cost is about $631 million. This rulemaking will not reduce the probability of a future spill to
zero; therefore, ‘‘B’’ in the table above represents the adjustment in annual avoided social costs expected from this rulemaking based on the nonzero remaining probability of a spill after this rule is put into place. Thus, the difference between the avoided costs with and without their rule represents its expected benefits. This remaining probability is uncertain. For example, to balance the $183 million annual cost imposed by these
regulations with the expected benefits, the reliability of the well control system needs to improve by about 29 percent ($183 million/$631 million).
Although we have found no studies that evaluate the degree of actual improvement that could be expected from dual mechanical barriers, negative pressure tests, and a seafloor ROV function test, we believe it reasonable to anticipate that such measures will increase the reliability of the
well control systems, and therefore that the benefits of this rulemaking justify the costs.
II. Request for Comments on Interim
Final Rule and Effective Date
This is an interim final rulemaking
with request for comments; it is
effective immediately upon publication.
The Administrative Procedure Act
(APA) requires that an agency publish a
proposed rule in the Federal Register
with notice and an opportunity for
public comment, unless the agency, for
good cause, finds that providing notice
and soliciting comments in advance of
promulgating the rule would be
impracticable, unnecessary, or contrary
to the public interest (5 U.S.C. 553(b)).
BOEMRE determined that there is good
cause for publishing this interim final
rule without prior notice and comment
based on its findings, consistent with
preliminary information that is available
as a result of investigations into the
Deepwater Horizon event, that certain
equipment, systems, and improved
practices are immediately necessary for
the safety of offshore oil and gas drilling
operations on the Outer Continental
Shelf (OCS), and that these improved
drilling practices are either not
addressed or not sufficiently detailed by
current regulations. Immediate
VerDate Mar<15>2010
17:55 Oct 13, 2010
Jkt 223001
imposition of the requirements
contained in this interim final rule is
necessary because BOEMRE views strict
adherence to improved safety practices
set forth herein as necessary to
achieving safer conditions that, together
with other wild well control and oil
spill response capabilities, will allow it
to permit future OCS drilling
operations. Following notice and
comment procedures would be
impracticable in these circumstances.
Furthermore, following notice and
comment procedures would be contrary
to the public interest because the delay
in implementation of this interim final
rule could result in harm to public
safety and the environment. Failure to
adhere to the safety practices required
by this interim final rule increases the
risk of a blowout and subsequent oil
spill, with serious consequences to the
health and safety of workers and the
environment.
As discussed in Section 5,
‘‘Justification for the Interim Final
Rulemaking,’’ while investigation and
information-gathering into the
Deepwater Horizon blowout and spill
continues, preliminary evidence
PO 00000
Frm 00006
Fmt 4701
Sfmt 4700
suggests problems with the Macondo
well’s line of defense, which could
include blowout preventer (BOP)
systems, casing and cementing
programs, and fluid displacement
procedures. Evidence further suggests
that it is unlikely that these problems
are unique to the Deepwater Horizon
event; for example, most BOPs used in
drilling on the OCS are of similar design
and are produced by a limited number
of manufacturers. The interim final
rule’s provisions thus incorporate
targeted measures to promote the
integrity of the well and enhance well
control, including provisions
specifically identified by the Safety
Measures Report as warranting
immediate implementation. For
example, the requirement that operators
have all well casing designs and
cementing systems/procedures certified
by a Professional Engineer.
Similarly, BOEMRE determined that
the immediate necessity for improved
equipment, systems, and practices also
provides good cause to impose an
immediate effective date. The APA
requires an agency to publish a rule not
less than 30 days before its effective
E:\FR\FM\14OCR2.SGM

emcdonald on DSK2BSOYB1PROD with RULES2
date, except as otherwise provided by
the agency for good cause found and
published with the rule (5 U.S.C.
553(d)(3)). Just as BOEMRE found that
providing notice and an opportunity to
comment is impracticable and contrary
to the public interest, BOEMRE finds
that a 30-day delay after publication of
this interim final rule compromises the
safety of offshore oil and gas drilling. To
the extent that the 30-day period is
intended to allow regulated parties to
adjust to new requirements, information
gathered by BOEMRE in advance of this
rulemaking indicates that the oil and gas
industry is well aware of the general
provisions in this interim final rule.
Most of the provisions in the rule were
identified in the Safety Measures
Report, and industry is already working
to implement them.
We note that in developing the Safety
Measures Report on which this interim
final rule is based, the Department
consulted with a wide range of experts
in state and Federal governments,
academic institutions, and industry and
advocacy organizations. In addition, the
draft recommendations of the Safety
Measure Report were peer reviewed by
seven experts identified by the National
Academy of Engineering (NAE). Further
explanation of the justification for this
interim final rulemaking is provided in
section V, ‘‘Justification for Interim Final
Rulemaking.’’
While BOEMRE will not solicit
comments before the effective date,
BOEMRE will accept and consider
public comments on this rule that are
submitted within 60 days of its
publication in the Federal Register.
After reviewing the public comments,
BOEMRE will publish a notice in the
Federal Register that will respond to
comments and will either:
1. Confirm this rule as a final rule
with no additional changes, or
2. Issue a revised final rule with
modifications, based on public
comments.
III. Overview of Requirements in the
Interim Final Rule
As recommended in the Safety
Measures Report, this interim final rule
imposes a number of prescriptive, nearterm requirements. Other longer-term
safety measures and performance-based
standards recommended in the Safety
Measures Report will be analyzed for
implementation in future rulemakings.
Information from the many
investigations and other information
sources will also be analyzed and
considered in future rulemakings. In
developing the Safety Measures Report
on which this interim final rule is
based, the Department consulted with
VerDate Mar<15>2010
17:55 Oct 13, 2010
Jkt 223001
experts in state and Federal government,
academic institutions, and industry and
advocacy organizations. In addition,
draft recommendations were peer
reviewed by seven experts identified by
the NAE.
The primary purpose of this interim
final rule is to clarify and incorporate
safeguards that will decrease the
likelihood of a blowout during drilling
operations on the OCS. The safeguards
address well bore integrity and well
control equipment, and this interim
final rule focuses on those two
overarching issues. This rule will
therefore promulgate OCS-wide
provisions that will:
1. Establish new casing installation
requirements,
2. Establish new cementing
requirements (incorporate American
Petroleum Institute (API) Recommended
Practice (RP) 65—Part 2, Isolating
Potential Flow Zones During Well
Construction),
3. Require independent third party
verification of blind-shear ram
capability,
4. Require independent third party
verification of subsea BOP stack
compatibility,
5. Require new casing and cementing
integrity tests,
6. Establish new requirements for
subsea secondary BOP intervention,
7. Require function testing for subsea
secondary BOP intervention,
8. Require documentation for BOP
inspections and maintenance,
9. Require a Registered Professional
Engineer to certify casing and cementing
requirements, and
10. Establish new requirements for
specific well control training to include
deepwater operations.
As stated, the intent of this interim
final rule is to improve safety related to
both well bore integrity and well control
equipment.
Well bore integrity provides the first
line of defense against a blowout by
preventing a loss of well control. Well
bore integrity includes appropriate use
of drilling fluids and the casing and
cementing program. Drilling fluids and
the casing and cementing program are
used to balance the pressure in the
borehole against the fluid pressure of
the formation, preventing an
uncontrolled influx of fluid into the
wellbore. The specific provisions in this
rule that address well bore integrity are:
1. Incorporating by reference API RP
65—Part 2, Isolating Potential Flow
Zones During Well Construction;
2. Submission of certification by a
Registered Professional Engineer that
the casing and cementing program is
appropriate for the purpose for which it

is intended under expected wellbore
pressure;
3. Requirements for two independent
test barriers across each flow path
during well completion activities (also
certified by a Registered Professional
Engineer);
4. Ensuring proper installation of the
casing or liner in the subsea wellhead or
liner hanger;
5. Approval from the District Manager
before displacing kill-weight drilling
fluid; and
6. Deepwater well control training for
rig personnel.
Well control equipment is the general
term for the technologies used to control
a well by mechanical means in the event
that other well control mechanisms fail.
Well control equipment includes
control systems that activate the BOPs,
either through a control panel on the
drilling rig or through Remotely
Operated Vehicles (ROVs) that directly
interface with the subsea BOP to
activate the appropriate rams. The
provisions in this rule that address well
control equipment include:
1. Submission of documentation and
schematics for all control systems;
2. A requirement for independent
third party verification that the blindshear rams are capable of cutting any
drill pipe in the hole under maximum
anticipated surface pressure (MASP);
3. A requirement for a subsea BOP
stack equipped with ROV intervention
capability. At a minimum, the ROV
must be capable of closing one set of
pipe rams, closing one set of blind-shear
rams, and unlatching the Lower Marine
Riser Package (LMRP);
4. A requirement for maintaining an
ROV and having a trained ROV crew on
each floating drilling rig on a
continuous basis;
5. A requirement for autoshear and
deadman systems for dynamically
positioned rigs;
6. Establishment of minimum
requirements for personnel authorized
to operate critical BOP equipment;
7. A requirement for documentation
of subsea BOP inspections and
maintenance according to API RP 53,
Recommended Practices for Blowout
Prevention Equipment Systems for
Drilling Wells;
8. Required testing of all ROV
intervention functions on the subsea
BOP stack during the stump test and
testing at least one set of rams during
the initial test on the seafloor;
9. Required function testing of
autoshear and deadman systems on the
subsea BOP stack during the stump test
and testing the deadman system during
the initial test on the seafloor; and

Report either identified as appropriate
for implementation through emergency
rulemaking, or which BOEMRE has
determined will significantly increase
OCS drilling safety and with which
operators can readily comply. The
following provides an explanation of
each of these sources and provisions.
PO 00000
Measures Report are implemented in the
interim final rule.
Emergency Rulemaking
Recommendations From Safety
Measures Report
The Safety Measures Report identified
four items for emergency rulemaking:
1. Develop secondary control system
requirements;
E:\FR\FM\14OCR2.SGM
14OCR2
Federal Register / Vol. 75, No. 198 / Thursday, October 14, 2010 / Rules and Regulations
2. Establish new blind-shear ram
redundancy requirements;
3. Establish new deepwater well
control procedure requirements; and
4. Adopt safety case requirements for
floating drilling operations on the OCS.
Of these four items, this interim final
rule addresses: 1. Secondary control
system requirements; and 3. deepwater
well control procedure requirements.
This interim final rule does not include:
2. New blind-shear ram redundancy
requirements; and 4. safety case
requirements for floating drilling
operations on the OCS.
BOEMRE determined that, while new
blind-shear ram redundancy
requirements are important to offshore
drilling safety, they are not appropriate
for inclusion in this interim final rule.
Installation of a second set of blindshear rams will require major
modifications to the BOP stack for most
rigs on the OCS. Compliance with such
a requirement is likely to take operators
from 1 year to 18 months. Inclusion of
a requirement that will necessitate a
period of 1 year or more to comply is
not appropriate for an interim final rule,
the purpose of which is to have
immediate effect. Given the necessary
compliance periods, BOEMRE believes
there will be sufficient opportunity to
proceed through a notice and comment
rulemaking. Operators should be aware,
however, that BOEMRE intends to
promptly initiate a notice and comment
rulemaking process to address this
issue. Specifically, operators should be
aware that BOEMRE is considering
regulations to require the installation of
a second set of blind-shear rams,
appropriately spaced to ensure that at
least one blind-shear ram cuts any drill
pipe in the hole and seals the wellbore
at any time. Operators should also be
aware that BOEMRE is likewise
considering requiring, through a notice
and comment rulemaking, a set of
casing shear rams capable of shearing
any casing in the hole.
This interim final rule addresses both
new well bore integrity requirements
and well control equipment
requirements. The well bore integrity
provisions impose requirements for
casing and cementing design and
installation, tighter cementing practices,
the displacement of kill-weight fluids,
and testing of independent well barriers.
These new requirements ensure that
there are additional physical barriers in
the well to prevent oil and gas from
escaping into the environment. These
new requirements related to well bore
integrity will considerably decrease the
likelihood of a loss of well control. The
well control equipment requirements in
this interim final rule will help ensure
the BOPs will operate in the event of an
emergency and that the ROVs are
capable of activating the BOPs.
Together, these new requirements will
help decrease the urgency of
immediately requiring blind-shear ram
redundancy on BOPs, and have factored
into BOEMRE’s decision to address such
requirements through a standard
rulemaking process.
63353
BOEMRE also determined not to
include safety case requirements for
floating drilling operations in this
interim final rule. A safety case is a
comprehensive, structured
documentation system to reduce
operating risks for offshore drilling. A
drilling safety case would establish risk
assessment and mitigation processes to
manage a drilling contractor’s controls
related to health, safety, and
environmental aspects of operations.
BOEMRE is evaluating how a drilling
safety case should be most appropriately
integrated with an overall Safety and
Environmental Management System
(SEMS) approach, which BOEMRE may
implement through a separate
rulemaking process. As directed in the
Safety Measures Report, BOEMRE will
work with offshore operators and
drilling contractors, appropriate
government agencies, and other
appropriate stakeholders to consider the
type of well construction interfacing
document that will best connect the
requirements of a safety case to existing
well design and construction
documents. BOEMRE therefore intends
to pursue adoption of appropriate safety
case requirements through a separate
rulemaking process once the necessary
analyses have been completed.

determined that it is appropriate for
inclusion in this interim final rule
because it is consistent with the intent
of the recommendations in the Safety

practices will increase the safety of
offshore oil and gas drilling operations
by improving cementing practices; they
also will support the other requirements

V. Justification for Interim Final
Rulemaking
Pursuant to the Outer Continental
Shelf Lands Act (OCSLA), the Secretary
has an affirmative obligation to ensure
that drilling operations undertaken on
the OCS are conducted in a manner that
is safe for the human, marine, and
coastal environment (43 U.S.C. 1332(6),
1334(a), 1347, and 1348; and 30 CFR
250.106). The April 20, 2010, blowout of
the BP Macondo well and the explosion
on the Deepwater Horizon killed 11
workers and resulted in the Nation’s
largest oil spill ever, with substantial
environmental and economic impacts.
On May 28, 2010, the Secretary
ordered the suspension of certain oil
and gas drilling operations in deepwater
PO 00000
Frm 00010
Fmt 4701
Sfmt 4700
(greater than 500 feet). On July 12, 2010,
the Secretary rescinded that order and
replaced it with a new decision ordering
the suspension in the Gulf of Mexico
(GOM) and Pacific regions of the
drilling of wells using subsea BOPs or
surface BOPs on a floating facility, with
certain exceptions for intervention
wells, injection and disposal wells,
abandonments, completions, and
workovers. This suspension order
applies by its terms until November 30,
2010, although the order notes that it
could be lifted earlier than that date.
As mentioned previously, on April
30, 2010, the President also directed the
Secretary to conduct a thorough review
of the Deepwater Horizon event and to
report within 30 days on additional

Federal Register / Vol. 75, No. 198 / Thursday, October 14, 2010 / Rules and Regulations
measures needed to improve the safety
of oil and gas operations on the OCS. On
May 27, 2010, the Secretary delivered
the Safety Measures Report to the
President. This Safety Measures Report
incorporated recommendations from
BOEMRE, as well as from a wide range
of experts from government, academia,
and industry. In developing the Safety
Measures Report on which this interim
final rule is based, the Department
consulted with a wide range of experts
in state and Federal government,
academic institutions, and industry and
advocacy organizations. In addition,
draft recommendations were peer
reviewed by seven experts identified by
the NAE.
Numerous investigations are ongoing,
and the precise causes of the well
blowout and explosion are not fully
known; however, the fact that a blowout
occurred clearly indicates problems
with the well’s line of defense, which
could include BOP systems, casing and
cementing programs, and fluid
displacement procedures. Accordingly,
it is not necessary to await certainty
regarding the cause of the blowout
before promulgating this interim final
rule.
Circumstances suggest that, while a
blowout and spill of this magnitude
have not occurred before on the OCS, it
is unlikely that the problems are unique
to the Deepwater Horizon and BP’s
Macondo well. As noted in the July 12,
2010, decision of the Secretary to
suspend certain offshore permitting and
drilling activities, most BOPs used in
drilling on the OCS are of similar design
and are produced by a limited number
of manufacturers. Furthermore, the
BOPs for the relief wells drilled to
intercept the Macondo well encountered
unexpected performance problems,
initially failing to pass new testing
procedures developed in response to the
Safety Measures Report, including
failure of the deadman and autoshear
functions. These multiple failures raise
red flags as to the reliability of BOPs to
adequately safeguard the lives of
workers and protect the environment
from oil spills in response to a large
blowout. They also suggest the need to
review regulations pertaining to well
casing and design, the other area of
likely failure in the Deepwater Horizon
event.
Even without the full results of the
pending investigations, the obvious
failures of well intervention and
blowout containment systems
demonstrate that previous regulatory
assumptions concerning their reliability
are inaccurate. The importance of these
systems in preventing catastrophic
blowouts and oil spills indicate that
VerDate Mar<15>2010
17:55 Oct 13, 2010
Jkt 223001
genuine harm could result from delay
and lead BOEMRE to conclude that
immediate regulations are needed to
better ensure the reliability of these
systems, and to protect the lives of
workers, human health, and the
environment.
This interim final rule therefore,
specifically addresses measures that
will increase the safety of these systems.
It imposes requirements to give greater
certainty that casing and cement design
and fluid displacement are adequate for
well bore integrity, and to enhance the
reliability of well control equipment.
The casing and cementing program
and fluid displacement procedures are
the first line of defense in preventing a
loss of well control that could lead to a
blowout. Casing and cement and
drilling fluids are used to ensure the
fluids in a formation do not enter the
wellbore during drilling and completion
operations. When a well is completed
and production begins, the casing and
cement continue to prevent
uncontrolled flow of fluids into the
wellbore. The integrity of the casing and
cement are critical to proper well
control. While the extent to which
cementing and casing failures
contributed to the Macondo blowout is
not yet fully known, preliminary
information suggests that the operator
may have failed to follow best industry
cementing and casing installation
practices. The current regulations
contain general cementing and casing
requirements, but they do not
specifically address best cementing and
casing installation practices. This
rulemaking will provide greater
assurance that all operators will follow
these safer practices, reducing the risk
of a loss of well control.
This interim final rule also
strengthens requirements for BOPs. In
the event of a loss of well control, rig
operators use the BOPs to regain control
of the well. This is done by closing the
various rams on the BOP stack, which
shut off the flow of formation fluids to
the surface. Secondary well control
system requirements (i.e., ROV
intervention capabilities and emergency
back-up BOP control systems) ensure
that rig operators are able to activate
various BOP rams in the event the
control system on the rig fails (e.g., loss
of power). Requirements in this interim
final rule impose new standards to
enhance BOP reliability, thereby
lessening the possibility of failures that
could lead to an uncontrolled blowout
and spill with potentially catastrophic
consequences for workers and the
environment.
Given the Deepwater Horizon blowout
and resulting spill, and because of the
PO 00000
Frm 00011
Fmt 4701
Sfmt 4700
63355
potential for grave harm to workers and
the human, marine, and coastal
environment from any additional
events, BOEMRE concludes that existing
regulations must be strengthened to
more fully protect offshore workers, the
environment, and the public, and that
this situation justifies immediate
imposition of the requirements of this
interim final rule.
This interim final rule applies to
ongoing operations not covered by the
Secretary’s July 12, 2010, suspension
decision in addition to those operations
that were suspended by that decision.
Immediate imposition of the
requirements of this rule is necessary for
both ongoing and suspended operations
to ensure that all operations proceed in
a more safe and reliable fashion in
protection of human health and the
environment. The July 12, 2010,
suspension expires by its terms on
November 30, 2010, and it could be
lifted earlier. A standard APA notice
and comment rulemaking process
would place the effective date of these
measures beyond the expiration date of
the suspension, which would mean that
these operations could resume without
the benefit of the new safety measures
being in place. Therefore, BOEMRE
believes that the delay associated with
notice and comment has the potential to
harm worker and public health and
safety and the environment, and further
justifies the immediate implementation
of this interim final rule to all OCS
drilling operations. To act otherwise has
the potential to risk worker and
environmental protection with
inadequate regulatory coverage.
BOEMRE is cognizant of the fact that
the Secretary has the ability to extend
the suspension of operations covered by
his July 12, 2010, decision, or to apply
the suspension to additional operations
on the OCS. Immediate application of
the safety measures in this interim final
rule, however, will improve the
reliability of well control systems,
thereby allowing all oil and gas
operations on the OCS to proceed in a
more safe and environmentally sound
manner.
BOEMRE believes that much of the oil
and gas industry is already well
informed of the general provisions in
this interim final rule, most of which
were identified in the Safety Measures
Report. Information gathered by
BOEMRE in advance of this rulemaking
indicates that BOP equipment
manufacturers, drilling contractors, and
operators are already working to address
the recommendations. Establishing
these requirements via an interim final
rule will allow these entities to make

Federal Register / Vol. 75, No. 198 / Thursday, October 14, 2010 / Rules and Regulations
informed financial and operational
decisions earlier.
As previously noted, these regulations
were developed without the benefit of
the conclusive findings from the
ongoing investigations into the root
causes of the explosions and fire on the
Deepwater Horizon. In the future, based
on the comments we receive on this rule
and the additional findings of ongoing
investigations, BOEMRE may issue
additional regulations or amendments to
these regulations that will be intended
to further increase the safety of offshore
oil and gas operations.
VI. Section-By-Section Discussion of
Requirements in the Interim Final Rule
emcdonald on DSK2BSOYB1PROD with RULES2
Documents Incorporated by Reference
(§ 250.198)
Code of Federal Regulations, Title 30—
MINERAL RESOURCES
BOEMRE is revising the title of
Chapter II to, ‘‘CHAPTER II—BUREAU
OF OCEAN ENERGY MANAGEMENT,
REGULATION AND ENFORCEMENT,
DEPARTMENT OF THE INTERIOR.’’ On
June 18, 2010, the Secretary of the
Interior changed the name of the
Minerals Management Service (MMS) to
the Bureau of Ocean Energy
Management, Regulation and
Enforcement (BOEMRE). This rule
updates the heading of Chapter II in
Title 30, Volume 2, of the Code of
Federal Regulations to reflect this
change.
Paragraph (a)(3) was added to clarify
that the documents incorporated by
reference into the regulations are
requirements. In the National
Technology Transfer and Advancement
Act of 1995, Congress directed Federal
agencies to use technical standards that
are developed or adopted by voluntary
consensus standards bodies. In
§ 250.198, BOEMRE incorporates by
reference many consensus technical
standards including recommended
practices, code requirements, and
specifications. The effect of
incorporating these standards into
Federal regulations is confirmed in
regulations issued by the Office of the
Federal Register (1 CFR 51.9(b)), which
requires agencies to inform the user that
an incorporated publication is a
requirement.
When BOEMRE incorporates a
document by reference, any
recommendations in the document will
be interpreted as requirements, unless
otherwise specified. For example, this
section incorporates API documents that
recommend certain actions using the
word should. In the Foreword to its
recommended practices, API explains
that the word shall indicates that the
VerDate Mar<15>2010
17:55 Oct 13, 2010
Jkt 223001
recommended practice has universal
applicability to the specific activity,
while the word should denotes a
recommended practice where a safe
comparable alternative practice is
available. Despite this explanation, for
API documents incorporated by
reference into this part, the terms should
and shall mean must. For example, API
RP 53, sections 17.10, 17.11, 17.12,
18.10, 18.11, and 18.12, are currently
incorporated by reference in
§ 250.446(a). By adding paragraph (a)(3)
to this interim final rule, which explains
that the words should and shall both
mean must, BOEMRE clarifies to the
operators that they must follow all of
the provisions of these API RP 53
sections.
Paragraph (h)(79) was added to this
section and incorporates by reference
API RP 65—Part 2, Isolating Potential
Flow Zones During Well Construction,
First Edition, May 2010. This document
contains best practices for zone isolation
in wells to prevent annular pressure
and/or flow through or past pressurecontainment barriers that are installed
and verified during well construction.
Barriers that seal wellbore and
formation pressures or flows may
include temporary pressure
containment barriers like hydrostatic
head pressure during cement curing,
and permanent ones such as mechanical
seals, shoe formations, and cement.
Other well construction (well design,
drilling, leak-off tests, etc.,) practices
that may affect barrier sealing
performance are addressed along with
methods to help ensure positive effects
or to minimize any negative ones. The
incorporation by reference of API RP
65—Part 2 addresses the Safety
Measures Report recommendation
II.B.3.7: Enforce Tighter Primary
Cementing Practices.
The citations for API RP 53 in
§ 250.198(h)(63) were updated to
include the requirements in § 250.516
and new § 250.617.
A consensus standard indicates
acceptance and recognition across the
industry that this technology is feasible.
For example, in its recommended
practice publications, including API RP
65—Part 2 and API RP 53, API explains
that its publications are intended to
facilitate the broad availability of
proven, sound engineering, and
operating practices. The recommended
practices are created with input from oil
and gas operators, drilling contractors,
service companies, consultants, and
regulators; therefore, the recommended
practices reflect an agreement that the
specified practices and technologies are
available and appropriate. Even though
the development of a standard does not
PO 00000
Frm 00012
Fmt 4701
Sfmt 4700
represent a 100% agreement by the task
group members, the process provides a
means for industry and regulatory
bodies to develop protocols for the
highly specialized equipment and
procedures used in offshore oil and gas
work. BOEMRE would not have the
proper resources to develop information
included in standards on its own (e.g.
deepwater, High Pressure, High
Temperature). BOEMRE regulatory
program benefits from using the
expertise in industry on offshore
operations through the standards
development process. Furthermore, in
the National Technology Transfer and
Advancement Act of 1995, Congress
directed Federal agencies to use
technical standards that are developed
or adopted by voluntary consensus
standards bodies (https://standards.gov/
standards_gov/nttaa.cfm).
When a copyrighted technical
industry standard is incorporated by
reference into our regulations, BOEMRE
is obligated to observe and protect that
copyright. BOEMRE provides members
of the public with Web site addresses
where these standards may be accessed
for viewing—sometimes for free and
sometimes for a fee. The decision to
charge a fee is decided by organizations
developing the standard.

What must my casing and cementing
programs include? (§ 250.415)
In this section, BOEMRE added a new
paragraph (f) requiring the operator to
include in its APD an evaluation of the
best practices identified in API RP 65—
Part 2, Isolating Potential Flow Zones
During Well Construction. We revised
paragraphs (c), (d), and (e) to
accommodate the new paragraph.
Incorporating this document by
reference will help ensure operators use
best practices when designing their
casing and cementing programs and will
help ensure the integrity of the well,
decreasing the risk of a loss of well
control. Operators must submit a
written description of their evaluation
to BOEMRE that includes the
mechanical barriers and cementing
practices the operators will use for each
casing string. Operators must exercise
due diligence in understanding the
variables involved when planning the
casing and cementing program.
The API RP 65—Part 2 addresses
mechanical barriers in section 3. A
mechanical barrier, as defined by this
document, is a verifiable seal achieved
by mechanical means between two
casing strings or a casing string and the
borehole that isolates all potential
flowing zones at or below the wellhead,
BOP, or diverter. The use of downhole
mechanical barriers is complementary
to properly executed cementing and not
a replacement. The applications of
subsurface mechanical barriers must be
chosen with care.
The API RP 65—Part 2, section 4,
addresses cementing practices and
factors affecting cementing. This section
requires that casing and cementing
programs address many of the key
drilling issues that affect the quality of
a primary cementing operation. Section
4 includes the best practices for the
factors that must be considered and
addresses the interrelationship between
drilling operations and cementing
success. BOEMRE is requiring operators
to document how they evaluated these
best practices, to ensure operators
consider them while developing their
casing and cementing programs.
BOEMRE believes that this is an
appropriate document to incorporate by
reference. The key to successful use of
this document for OCS cementing
operations is implementation. The
regulations will require that the operator
address the document during the
preparation of the APD and describe the
cementing practices and barriers used
for casing string. Including this
information on the APD will help assure
VerDate Mar<15>2010
17:55 Oct 13, 2010
Jkt 223001
best practices are used for a particular
operation. Incorporating this document
will not address all issues associated
with cementing practices; however,
doing so gives the agency the ability to
evaluate best cementing practices on a
case by case basis. Additional
cementing requirements may be
identified as results of the many
investigations of the Deepwater Horizon
event but until then BOEMRE believes
this is the best approach to requiring
best cementing practices. These
additions will allow BOEMRE to
confirm that well construction is based
on a complete evaluation of all critical
factors (including mechanical barriers
and cementing practices) involved in a
casing and cementing program. This
new requirement addresses Safety
Measures Report recommendation
II.B.3.7: Enforce Tighter Primary
Cementing Practices.
What must I include in the diverter and
BOP descriptions? (§ 250.416)
In this section, paragraph (d) was
revised to include the submission of a
schematic of all control systems,
including primary control systems,
secondary control systems, and pods for
the BOP system. This requirement
applies to both surface and subsea BOP
systems. This will provide
documentation for all control systems to
BOEMRE. The location of the controls
must be included. Secondary control
systems include, but are not limited to,
the following: ROV intervention panels
located on the BOP, autoshear and
deadman systems, power sources of
each system, back up power sources,
and acoustic systems.
In this section, paragraph (e) was
revised to require the operator to submit
independent third party verification and
supporting documentation that shows
the blind-shear rams installed in the
BOP stack are capable of shearing any
drill pipe in the hole under maximum
anticipated surface pressure, as
recommended in the Safety Measures
Report and included in NTL No. 2010–
N05. This requirement applies to both
surface and subsea BOP systems. The
benefit of an independent third party is
that it provides an objective and
technically-informed review to properly
verify capabilities of the blind-shear
rams. Requiring independent third party
verification and information about the
blind-shear rams will help ensure that
the appropriate shear rams are installed
in the BOP. The documentation must
include test results and calculations of
shearing capacity of all pipe to be used
in the well including correction for
maximum anticipated surface pressure.
Shearing capability tests can be
PO 00000
Frm 00013
Fmt 4701

performed on the drill pipe that requires
the highest shear pressure. The operator
must include a discussion on how the
drill pipe used during the shear test
required the highest shear pressure and
was the most difficult to shear. The
interim final rule will codify the
section, ‘‘Verification that Blind-shear
Rams Will Shear Pipe in the Hole’’ in
NTL No. 2010–N05.
Paragraph (f) was added to require
independent third party verification that
a subsea BOP stack is designed for the
specific equipment used on the rig. The
independent third party must verify that
the subsea BOP stack is compatible with
the specific well location, well design,
and well execution plan. Information
showing that the shear rams are
appropriate for the project must be
included. The independent third party
must also verify that the subsea BOP
stack has not been damaged or
compromised from previous service.
Last, the independent third party must
verify that a subsea BOP stack will
operate in the conditions in which it
will be used. This will ensure that all
factors of drilling with subsea BOPs are
considered when choosing well control
equipment. This requirement applies to
all APDs that request to use a subsea
BOP stack. It applies to completion,
workover, or abandonment operations.
The interim final rule will codify the
section, ‘‘BOP Compatibility Verification
for All Wells’’ in NTL No. 2010–N05.
Paragraph (g) was added and
describes the criteria and
documentation for an independent third
party that must be submitted with the
APD to BOEMRE for review. This is to
ensure that the independent third party
is capable of providing both an objective
and a technically informed validation of
the subjects being reviewed. The
independent third party must be a
technical classification society; an API
licensed manufacturing, inspection,
certification firm; or licensed
professional engineering firm capable of
providing the verifications required
under this part. The independent third
party must not be the original
equipment manufacturer. The original
equipment manufacturer is excluded
because it has a financial interest in
equipment being evaluated. Equipment
manufacturers that do not have a
financial interest in the equipment
being evaluated may serve as an
independent third party certifier if
otherwise qualified. The operator must
provide evidence to BOEMRE that the
firm it is using is reputable; specifically,
the firm or its employees hold
appropriate licenses to perform the
verification in the appropriate
jurisdiction, the firm carries industry-

standard levels of professional liability
insurance, and the firm has no record of
violations of applicable law. Prior to any
shearing ram tests or inspections, the
operator must also notify the District
Manager 24 hours in advance. The
operator must ensure an official
representative of BOEMRE access to the
location to potentially witness any
testing or inspections, or to verify
information submitted to BOEMRE. This
approach to document the qualifications
of the independent third party is the
same approach being followed for the
documenting the independent third
party required by NTL No. 2010–N05.
The revised requirements in
paragraph (d) address Safety Measures
Report recommendation I.B.5:
Secondary Control System
Requirements and Guidelines. The
requirements in paragraph (e) address
Safety Measures Report
recommendation I.C.7: Develop New
Testing Requirements. The new
requirements in paragraph (f) address
Safety Measures Report
recommendation I.A.2: Order BOP
Equipment Compatibility Verification
for Each Floating Vessel and for Each
New Well. The criteria required for the
independent third party are also
addressed in NTL No. 2010–N05. These
requirements will help ensure that the
rig operator has the appropriate control
systems in place, aiding the rig
operator’s ability to regain control of a
well in the event of a loss of well
control.
What additional information must I
submit with my APD? (§ 250.418)
In this section, new paragraph (h) was
added that requires the operator to
submit certifications of their casing and
cementing program signed by a
Registered Professional Engineer. The
Registered Professional Engineer must
be registered in a State in the United
States but does not have to be a specific
discipline. Certification by a Registered
Professional Engineer will increase the
likelihood that the casing and
cementing program has been properly
designed and implemented, and will
provide adequate well control. The
Registered Professional Engineer will
certify that there will be at least two
independent tested barriers across each
flow path during well completion
activities. The Registered Professional
Engineer will also certify that the casing
and cementing design is appropriate for
the purpose for which it is intended
under expected wellbore conditions.
The operator must submit this
certification to BOEMRE along with the
APD. Paragraph (g) was revised to
accommodate new paragraph (h). The
VerDate Mar<15>2010

Jkt 223001
interim final rule will codify
requirements addressed under the
section, ‘‘Well Design and Construction
for All Wells’’ in NTL No. 2010–N05.
These requirements for additional
barriers, and the certification of the
cement design, will decrease the
likelihood of a blowout. These
requirements apply to new wells,
sidetracks, bypasses, or deepened wells.
In this section, a new paragraph (i)
was added requiring the operator to
submit a description of qualifications of
any independent third party. Operators
must formally notify BOEMRE of their
independent third parties. The
description must be submitted with the
APD and may include the following:
1. Name and address of the individual
or organization;
2. Size and type of the organization or
corporation;
3. Previous experience as a Certified
Entity, Certified Verification Agent
(CVA), or similar third-party
representative;
4. Experience in design, fabrication,
or installation of BOPs and related
equipment;
5. Technical capabilities (including
professional certifications and
organizational memberships) of the
third party or the primary staff to be
associated with the certifying functions
for the specific project;
6. In-house availability of, or access
to, appropriate technology (i.e.,
computer modeling programs and
hardware, testing materials, and
equipment);
7. Ability to perform and effectively
manage certifying functions,
inspections, and tests for the specific
project considering current resource
availability;
8. Previous experience with
regulatory requirements and procedures;
9. Evidence that the third party is not
owned or controlled by the designer,
manufacturer, or supplier of the system
or its subsystems to be inspected or
tested under regulations applicable to
this device or any manufacturer of
similar equipment or material;
10. The level of work to be performed
by the third party; and
11. A list of documents and
certifications expected to be furnished
to BOEMRE by the third party.
The new requirements address the
Safety Measures Report

What well casing and cementing
requirements must I meet? (§ 250.420)
In this section, new paragraph (a)(6)
was added that requires the operators to
submit certification of their casing and
cementing program signed by a
Registered Professional Engineer (see
discussion under section 250.418,
above). The Registered Professional
Engineer must be registered in a State in
the United States. As mentioned
previously, the Registered Professional
Engineer does not have to be from a
specific discipline, but must be capable
of reviewing and certifying that the
casing design is appropriate for the
purpose for which it is intended under
expected wellbore conditions. The
Registered Professional Engineer will
certify that there will be at least two
independent tested barriers, including
one mechanical barrier, across each flow
path during well completion activities.
The Registered Professional Engineer
will also certify the casing and
cementing design is appropriate for the
purpose for which it is intended under
expected wellbore conditions. The
operator must submit this certification
to BOEMRE along with the APD. The
operator should not deviate from the
certified procedure; if the operator
deviates from the certified procedures,
they must contact the appropriate
District Manager. Paragraphs (a)(4) and
(a)(5) were revised to accommodate the
new paragraph (a)(6). The interim final
rule will codify the section, ‘‘Well
Design and Construction for All Wells’’
in NTL No. 2010–N05. The certification
of the casing and cementing program
will help ensure that the appropriate
program is used for the well and
decrease the likelihood of a blowout.
A new paragraph (b)(3) was also
added, requiring the operator to install
dual mechanical barriers in addition to
cement for the final casing string (or
liner if it is the final string), to prevent
flow in the event of a failure in the
cement. These may include dual float
valves, or one float valve and a
mechanical barrier. The operator must
document the installation of the dual
mechanical barriers and submit this
documentation to BOEMRE 30 days
after installation. References to days in
this rule are always in calendar days.
The interim final rule will codify the
section, ‘‘Well Design and Construction
for All Wells’’ in NTL No. 2010–N05.
These new requirements will help
ensure that the best casing and
cementing design will be used for a
specific well. The new requirements in
paragraphs (a)(6) and (b)(3) address the

What are the requirements for pressure
testing casing? (§ 250.423)
This section was reorganized to
accommodate new requirements: the
current regulations were redesignated as
paragraph (a) and new paragraphs (b)
and (c) were added. Paragraph (b)
requires the operator to perform a
pressure test on the casing seal assembly
to ensure proper installation of casing or
liner in the subsea wellhead or liner
hanger. This must be done for
intermediate and production casing
strings or liner. To install casing in the
subsea wellhead, the operator runs and
lands the casing hanger tool, cements
the casing, latches the casing hanger in
place, and finally pressure sets and tests
the seal. This test ensures that the
casing hanger latching mechanism, or
lockdown mechanism, is engaged,
ensuring the integrity of the casing. The
operator must submit the test
procedures and criteria used for a
successful test with the APD to
BOEMRE for approval. The operator
must record the test results and make
the results available to BOEMRE upon
request. As required in § 250.466,
records for well operations must be kept
onsite while drilling activities continue.
The interim final rule will codify
requirements addressed under the
section, ‘‘Well Design and Construction
for All Wells’’ in NTL No. 2010–N05.
Paragraph (c) requires the operator to
perform a negative pressure test on all
wells to ensure proper installation of
casing for the intermediate and
production casing strings. The operator
must submit the procedures and criteria
for a successful test with the APD for
approval. The operator must record the
test results and make available to
BOEMRE upon request. A negative
pressure test will help ensure that the
casing, along with the cement, provides
a seal.
The new requirements in this section
will help ensure proper casing
installation and evaluate the integrity of
the casing and cement. The new
requirements in this section address the
Safety Measures Report
recommendations II.B.1.3: New Casing
and Cement Design Requirements: Two
Independent Tested Barriers; II.B.2.5:
New Casing Installation Procedures; and
II.B.2.6: Develop Additional
Requirements or Guidelines for Casing
Installation.
What are the requirements for a subsea
BOP system? (§ 250.442)
This section requires that when
drilling with a subsea BOP system, the
VerDate Mar<15>2010
17:55 Oct 13, 2010
Jkt 223001
BOP system must be installed before
drilling below the surface casing. The
table in this section outlines the
requirements, including:
a. The minimum number of each type
of BOP,
b. dual-pod control systems,
c. accumulator operations,
d. ROV intervention,
e. maintaining an ROV and ROV crew
training,
f. autoshear and deadman capability
and optional acoustic system for
dynamically positioned rigs,
g. accidental disconnect avoidance,
h. BOP control panel labels,
i. BOP management system,
j. personnel training for BOP
equipment,
k. marine riser removal, and
l. avoiding ice scour.
Paragraph (a) was revised to clarify
that the blind-shear rams must be
capable of shearing any drill pipe in the
hole under maximum anticipated
surface pressures. When drilling with a
subsea BOP stack, the operator must
have a minimum of four remote
controlled hydraulically operated BOPs.
The BOPs must include one annular
preventer, two sets of pipe rams, and
one set of blind-shear rams.
The requirement in paragraph (b) to
have an operable dual-pod control
system and the requirement in
paragraph (c) to follow API RP 53,
Section 13.3, Accumulator Volumetric
Capacity, were not revised. The operator
must meet the volume capacities for all
subsea accumulators and must meet the
closing times specified in API RP 53,
Section 13.3.5, Accumulator Response
Time: The BOP control system must be
capable of closing each ram BOP in 45
seconds or less; closing time must not
exceed 60 seconds for annular BOPs;
operating response time for choke and
kill valves must not exceed the
minimum observed ram BOP close
response time; and time to unlatch the
LMRP must not exceed 45 seconds.
Requirements related to ROV
intervention in paragraph (d) were
added. The subsea BOP stack must be
equipped with ROV intervention
capability to operate one set of pipe
rams and one set of blind-shear rams as
well as unlatch the LMRP. The BOP–
ROV interface must allow sufficient
volume to actuate all required functions.
This requirement will ensure that the
dedicated ROV has the capacity to close
the BOP functions and secure the well
in sufficient time during a well control
event. The interim final rule will codify
the section, ‘‘ROV Hot Stab Function
Testing of the ROV Intervention Panel’’
in NTL No. 2010–N05.
In paragraph (e), the operator is
required to maintain an ROV and have
PO 00000
Frm 00015
Fmt 4701
Sfmt 4700
63359
a trained ROV crew on each floating
drilling rig on a continuous basis. The
crew must be trained in the operation of
the ROV. The training must include
simulator training on stabbing into an
ROV intervention panel on a subsea
BOP stack. This requirement will help
provide assurance that a properly
trained crew is available for use during
an emergency situation.
Requirements related to autoshear and
deadman systems in paragraph (f) were
added. Autoshear, deadman, and
acoustic systems are all emergency
systems. Dynamically positioned rigs
must have autoshear and deadman
systems. Autoshear system is defined as
a safety system that is designed to
automatically shut in the wellbore in
the event of an unplanned disconnect of
the LMRP. When the autoshear is
armed, a disconnect of the LMRP closes
the shear rams. Deadman system is
defined as a safety system that is
designed to automatically close the
wellbore in the event of a simultaneous
absence of hydraulic supply and signal
transmission capacity in both subsea
control pods. Both autoshear and
deadman are considered ‘‘rapid
discharge’’ systems. Dynamically
positioned rigs may also use an acoustic
system. An acoustic signal transmission
may be used as an emergency backup
that controls critical BOP functions.
However, BOEMRE believes additional
evaluation is necessary to determine the
reliability of acoustic signal
transmission as a mandatory backup
control system. Industry, academics and
other stakeholders have raised concerns
about how the differences in water
temperatures between water layers
(deepwater thermocline) will affect the
transmission of the acoustic signal to
the BOP stack when installed in
deepwater. Similar concerns were raised
about how different salinities between
water layers, noise from a wild well, or
other subsea noise may interfere with
the successful transmission of the
acoustic signals to the BOP stack.
Further investigation of these concerns
is needed before deciding to require the
installation of an acoustic backup
control system. The interim final rule
will codify the section, ‘‘Secondary
Control System Requirements and
Guidelines for Subsea BOP Stacks’’ in
NTL No. 2010–N05.
In paragraph (g), the operator is
required to have operational or physical
barrier(s) on BOP control panels to
prevent accidental use of disconnect
functions. The operator must
incorporate enable buttons on control
panels to ensure two-handed operation
for all critical functions. The new
requirements in this paragraph will

reduce the chances of an accidental
disconnect by requiring two separate
actions to activate all critical functions.
In paragraph (h), the operator is
required to clearly label all control
panels for the subsea BOP system. The
operator must include all BOP controls
such as hydraulic control panels and
ROV interface on the BOP. The new
requirements in this paragraph will help
to ensure that the correct function is
executed. The labeling of all functions
will also assist in proper usage in an
emergency situation.
In paragraph (i), the operator is
required to develop and use a
management system for operating the
BOP system. This includes guidance to
prevent accidental or unplanned
disconnects of the system. This
management system must include
written procedures for operating the
BOP stack and LMRP, and minimum
knowledge requirements for personnel
authorized to operate and maintain BOP
components. A copy of these written
procedures should be maintained on the
drilling rig and in other readily
accessible locations. These procedures
must be made available to all relevant
personnel. The new requirements in this
paragraph will help to ensure that the
correct function is executed in an
emergency situation.
Paragraph (j) requires the operator to
establish minimum requirements for
personnel authorized to operate critical
BOP equipment. This training must
include deepwater well control theory
and practice in accordance with 30 CFR
part 250, subpart O, and a
comprehensive knowledge of BOP
hardware and control systems.
Paragraphs (k) and (l) are currently
required, but were reformatted into the
table. Paragraph (k) requires the
operator to displace the fluid in the riser
with seawater before removing the
marine riser; while conducting this
operation, the operator must maintain
sufficient hydrostatic pressure on the
well or take other suitable precautions
to compensate for the reduction in
pressure to maintain well control.
Paragraph (l) requires that when drilling
in an ice-scour area, the BOP stack must
be installed in a glory hole (a depression
deep enough that the equipment is
protected).
These requirements help ensure
enhanced operability of subsea BOP
systems. These requirements will also
help to ensure that the proper personnel
are trained to have a comprehensive
knowledge of well control equipment,
maintain well control equipment,
operate essential well control
equipment, and manage a well control
situation.

What are the BOP maintenance and
inspection requirements? (§ 250.446)
Paragraph (a) of this section was
changed to require the operator to
document the maintenance and
inspections of their BOP system. The
requirement that BOP maintenance and
inspections must meet or exceed the
provisions of Sections 17.10 and 18.10,
Inspections; Sections 17.11 and 18.11,
Maintenance; and Sections 17.12 and
18.12, Quality Management; described
in API RP 53, Recommended Practices
for Blowout Prevention Equipment
Systems for Drilling Wells (incorporated
by reference as specified in § 250.198)
was not changed. The operator must
document the procedures used, record
the results, and make the results
available to BOEMRE upon request. The
operator must maintain the records on
the rig for 2 years or from the date of
the last major inspection, whichever is
longer.
The BOP maintenance, inspections,
and quality management are essential
components to ensuring BOP integrity
and operability. According to API RP
53, Section 17.10 (surface BOPs) and
Section 18.10 (subsea BOPs), operators
must perform a between-well
inspection, a visual inspection of
flexible choke and kill lines, and a
major 3–5 year inspection. According to
API RP 53, Section 17.11 (surface BOPs)
and Section 18.11 (subsea BOPs),
operators are required to maintain BOP
manuals, connections, replacement
parts, torque requirements, equipment
storage, lubricants and hydraulic fluids,
weld repairs, and mud/gas separators.
According to API RP 53, Section 17.12
(surface BOPs) and Section 18.12
(subsea BOPs), operators are required to
have a planned maintenance system,
with equipment identified, tasks
specified, and the time intervals
between tasks stated. Records of
maintenance performed and repairs
made must be retained on file at the rig
site or readily available.

What additional BOP testing
requirements must I meet? (§ 250.449)
New paragraphs (j) and (k) were
added and paragraphs (h) and (i) were
revised to accommodate the new
paragraphs. New paragraph (j) requires
the testing of ROV intervention
functions on a subsea BOP stack. The
ROV intervention functions must be
tested during the stump test. This test
must include ensuring that the hot stabs
are function tested and are capable of
actuating one set of pipe rams and one
set of blind-shear rams, as well as
unlatching the LMRP. The operator
must also test at least one set of rams
during the initial test on the seafloor.
The BOP–ROV interface must allow
sufficient volume to actuate all required
functions. The operator must document
the test results and make them available
to BOEMRE upon request. This will
help to ensure that the ROV and hot
stabs are capable of actuating the BOP
rams and LMRP disconnect. The interim
final rule will codify requirements
addressed under the section, ‘‘ROV Hot
Stab Function Testing of the ROV
Intervention Panel’’ in NTL No. 2010–
N05; which required testing of ROV
intervention functions during the stump
test. The interim final rule will also
require function testing during the
initial test on the seafloor. A successful
test will help ensure that the ROV and
BOP are capable of operating as
designed under conditions at water
depth.
New paragraph (k) requires function
testing of the autoshear and deadman
systems on the BOP stack during the
stump test. The operator must submit
the testing procedures for these
requirements with the APD or APM for
BOEMRE approval. This should include
the sequence of BOP functions that will
activate when the autoshear and
deadman systems are triggered. These
requirements will help to ensure that a
well is secured in an emergency
situation, loss of power, or accidental
disconnect, preventing the possible loss
of well control. The ROV intervention

What must I do in certain situations
involving BOP equipment or systems?
(§ 250.451)
A new item was added to the table,
requiring the operator to perform a full
pressure test when the blind-shear rams
or casing shear rams are used in an
emergency. Following activation of the
blind-shear rams or casing shear rams,
in which pipe or casing is sheared
during a well control situation, the
operator must retrieve and physically
inspect the BOP and conduct a full
pressure test of the BOP stack, after the
situation is fully controlled. This will
help ensure the integrity of the BOP and
that the BOP will fully function and
hold pressure after the event. If rams,
sealing elements, or other equipment are
damaged, they must be replaced or
repaired.

Well Control Issues
While the content of these future
rulemakings will depend in part on the
findings of the various investigations,
BOEMRE anticipates that future rules
will focus on well control issues. More
specifically this will include:
1. Cementing and casing—BOEMRE
anticipates examining the need for
additional cement evaluation

procedures and training needs for
personnel involved in cementing and
casing operations, and intends to
incorporate findings as appropriate from
the investigations related to the
Deepwater Horizon event.
2. Fluid displacement—BOEMRE
intends to further evaluate the
effectiveness of new fluid displacement
requirements to determine if it needs to
establish different or enhanced fluid
displacement procedures.
3. BOPs—BOEMRE anticipates
rulemaking to address BOP
recommendations resulting from the
joint BOEMRE and United States Coast
Guard investigation of the Deepwater
Horizon event. Rulemaking will also
likely address the requirement to have
two sets of blind shear rams as
recommended in the Safety Measures
Report and discussed previously.
Rulemakings will also likely consider
requirements for casing shear rams,
minimum number of pipe rams, second
annular preventer for subsea BOP
stacks, and electronic BOP logs. Another
area mentioned in the Safety Measures
Report is the need for periodic
certification of the BOP stack or specific
BOP components. BOEMRE wishes to
undertake additional research on how
these certifications should be done and
how often they should occur.
4. Secondary control systems and
ROVs—Future rulemaking may address
autoshear and deadman requirements
for all rigs with subsea BOP stacks,
enhanced ROV intervention capability,
and subsea accumulator volumes to
ensure fast closure of BOPs and choke
and kill lines. The need for effective
tertiary control systems, such as an
acoustic system, will also be examined
and addressed as appropriate.
5. Wild-well intervention
techniques—BOEMRE will conduct
research on this topic and evaluate the
progress industry has made to establish
deepwater wild-well intervention as it
moves forward with rulemaking on wild
well intervention.
6. Industry training—BOEMRE will
investigate safety training requirements
for deepwater drilling operations and
determine the appropriate manner to
regulate the training of personnel.
7. Oil spill response—BOEMRE
anticipates future rulemaking to address
the capture and disposition of oil
released from a deepwater well blowout
at the seafloor.
8. Organization and safety
management—The Safety Measures
Report recommended that the DOI
evaluate the need to require all or part
of the International Association of
Drilling Contractors’ Health, Safety, and
Environmental Case Guidelines for

Mobile Drilling Units. BOEMRE will
evaluate the guidelines and determine
how they will best fit with SEMS
regulations that are being considered by
BOEMRE for final publication in a
separate rulemaking. BOEMRE
published a notice of proposed
rulemaking on SEMS requirements on
June 17, 2009 (74 FR 28639).
Technical Consensus Standards
BOEMRE is aware that various
organizations which support the
offshore oil and gas industry are also
studying the possible causes of the
Deepwater Horizon event. Based on
their findings, these organizations may
make recommendations to their
members on practices to increase the
safety of offshore oil and gas operations
in general with specific
recommendations related to deepwater
drilling operations. BOEMRE is
reviewing the following subjects:
1. API Documents Concerning
Cementing Practices
In § 250.198 of this interim final rule,
BOEMRE incorporates API RP 65—Part
2, Isolating Potential Flow Zones During
Well Construction, which summarizes
best practices and addresses basic issues
associated with cementing practices.
The API has additional documents that
address cementing practices in more
detail.
2. Discussion of Additional
Specifications and Recommended
Practices
API Spec 16A: Specification for DrillThrough Equipment
This standard specifies requirements
for performance, design, materials,
testing and inspection, welding,
marking, handling, storing, and
shipping of drill-through equipment
used for drilling for oil and gas. It also
defines service conditions in terms of
pressure, temperature, and wellbore
fluids for which the equipment will be
designed. This standard is applicable to,
and establishes requirements for, the
following specific equipment: ram
BOPs; ram blocks, packers, and top
seals; annular BOPs; annular packing
units; hydraulic connectors; drilling
spools; adapters; loose connectors; and
clamps.
API Spec 16D: Specification for Control
Systems for Drilling Well Control
Equipment and Control Systems for
Diverter Equipment
This specification provides design
standards for systems used to control
the BOP and associated valves that
control well pressure during drilling
operations. Diverter control systems are
PO 00000
Frm 00019
Fmt 4701
Sfmt 4700
63363
included in this specification because
they are included in the BOP control
system. This specification addresses the
following categories: control systems for
surface BOP stacks, control systems for
subsea BOP stacks, discrete hydraulic
control systems for subsea BOP stacks,
electro-hydraulic/multiplex control
systems for subsea BOP stacks, control
systems for diverter equipment,
auxiliary equipment control systems
and interfaces, emergency disconnect
sequenced systems (EDS), backup
systems, and special deepwater/harsh
environment features.
Certain standards in API Spec. 16D
are of particular interest. These include
optional sections—5.7 Emergency
Disconnect Sequenced Systems (EDS),
5.8 Backup Control Systems, and 5.9
Special Deepwater/Harsh Environment
Features. The EDS systems are required
for floating drilling rigs in order to
quickly disconnect the riser in the event
of an inability to maintain rig position
within a prescribed watch circle.
Backup Control Systems include
standards on acoustic systems, ROV
control systems, LMRP recovery
systems, and backup power supply. The
Deepwater/Harsh Environment features
give specifications for autoshear and
deadman systems.
API Spec 17D: Specification for Subsea
Wellhead and Christmas Tree
Equipment
This specification was formulated to
provide for the availability of safe,
dimensionally, and functionally
interchangeable subsea wellhead,
mudline, and tree equipment. The
technical content provides requirements
for performance, design, materials,
testing, inspection, welding, marking,
handling, storing, and shipping. Critical
components are those parts having a
requirement specified in this document.
Rework and repair of used equipment
are beyond the scope of this
specification.
API Recommended Practice 17H; ISO
13628–8: Remotely Operated Vehicle
(ROV) Interfaces on Subsea Production
Systems
This recommended practice gives
functional requirements and guidelines
for ROV interfaces on subsea production
systems for the petroleum and natural
gas industries. It is applicable to both
the selection and use of ROV interfaces
on subsea production equipment, and
provides guidance on design as well as
the operational requirements for
maximizing the potential of standard
equipment and design principles. The
auditable information for subsea
systems this document offers allows
E:\FR\FM\14OCR2.SGM

interfacing and actuation by ROVoperated systems, while it identifies
issues that have to be considered when
designing interfaces on subsea
production systems. The framework and
detailed specifications set out enable the
user to select the correct interface for a
specific application.
API Recommended Practice 53:
Recommended Practices for Blowout
Prevention Equipment Systems for
Drilling Wells
This recommended practice provides
guidance for installation and testing of
surface and subsea BOP equipment
systems. This equipment system
consists of a BOP, choke and kill lines,
marine riser, and auxiliary equipment.
The primary function of a BOP
equipment system is to confine wellbore
fluids, provide a means to add fluids,
and allow controlled volumes to be
withdrawn from the wellbore. This
recommended practice also addresses
diverter systems.
Other Items for Consideration
BOEMRE is also studying the
following issues:
1. Following the certification of the
BOP to meet the one-time requirement
of NTL No. 2010–N05, frequency and
conditions for recertification
requirements.
2. Requirements for BOP equipment
and other components of the BOP stack
such as control panels, communication
pods, accumulator systems, and choke
and kill lines and the adequacy of API
Spec 16A.
3. Standardization of the BOP–ROV
interface to improve intervention
capabilities.
4. Issues related to requiring a subsea
isolation device that is independent of
the BOP stack that is capable of
operating critical functions that will
shut in a well in emergency situations.

of $100 million or more on the
economy. The following discussion
summarizes a detailed cost-benefit
analysis that is available on https://
www.Regulations.gov. Use the keyword/
ID ‘‘BOEM–2010–0034’’ to locate the
docket for this rule.
Various events around the world as
well as the US over the years
demonstrate that catastrophic oil spills

17:55 Oct 13, 2010
Jkt 223001
can and do occur. The costs associated
with such spills can be tremendous. As
a matter of policy, BOEMRE has decided
that any reasonable measures to reduce
the risks of another catastrophic spill
occurring on the OCS should be put in
place and enforced. The requirements
included in this rulemaking are such
measures. They were identified in the
May 27, 2010 report, Increased Safety
Measures for Energy Development on
the Outer Continental Shelf, for which
the draft recommendations were peerreviewed by seven experts identified by
the National Academy of Engineering.,
or identified by industry or academic
experts in materials presented to
BOEMRE. While the estimated costs of
this rulemaking, as reflected in the
compliance costs of the enumerated
requirements of approximately $180
million per year, have a strong
foundation and are based on surveys of
public and industry sources,
quantification of the benefits is
uncertain. The benefits are represented
by the avoided costs of a catastrophic
spill, which are estimated under the
stipulated scenario as being $16.3
billion per spill avoided. These
regulations will reduce the likelihood of
another blowout and associated spill,
but the risk reduction associated with
the specific provisions of this
rulemaking cannot be quantified
because there are many complex factors
that affect the risk of a blowout event.
As noted by the Secretary of the Interior
in his July 12 decision memo
suspending certain drilling activities,
drilling accidents can have a profound,
devastating impact on the economic and
environmental health of a region. The
measures codified in this rule will
reduce the likelihood of such an event
in the future, at a cost that is not
prohibitive, and therefore this
rulemaking is justified.
The purpose of a benefit-cost analysis
is to provide policy makers and others
with detailed information on the
economic consequences of the
regulatory requirements. The benefitcost analysis for this rule was conducted
using a scenario analysis. The benefitcost analysis considers a regulation
designed to reduce the likelihood of a
catastrophic oil spill. The costs are the
compliance costs of imposed regulation.
If another catastrophic oil spill is
prevented, the benefits are the avoided
costs associated with a catastrophic oil
spill (e.g., reduction in expected natural
resource damages owing to the
reduction in likelihood of failure).
Avoided cost is an approximation of
the ‘‘true’’ benefits of avoiding a
catastrophic oil spill. A benefits transfer
approach is used to estimate the
PO 00000
Frm 00020
Fmt 4701
Sfmt 4700
avoided costs. The benefits transfer
method estimates economic values by
transferring existing benefit calculations
from studies already completed for
another location or issue to the case at
hand. Accordingly, none of the avoided
costs used for a hypothetical
catastrophic spill rely upon, or should
be taken to represent, our estimate for
the BPDH event commencing on April
20, 2010.
Three new requirements account for
virtually all of the compliance costs
imposed by this regulation (1) use of
dual mechanical barriers in addition to
cement barriers in the final casing string
to prevent hydrocarbon flow in the
event of cement failure, (2) application
of negative pressure tests to all
intermediate and the production casing
strings to ensure their proper
installation, and (3) maintenance of
standby ROV capability to close BOP
rams and testing that capability after the
BOP has been installed on the sea floor.
BOEMRE estimates that these three
requirements will impose compliance
costs of approximately $174 million per
year, representing 95 percent of the total
annual compliance costs of $183 million
associated with this rulemaking. These
cost estimates were developed by
BOEMRE based on public data sources
and confidential information provided
by several offshore operators and
drilling companies.
On the benefit side, the avoided costs
for a hypothetical deepwater blowout
resulting in a catastrophic oil spill are
estimated to be about $16.3 billion (in
2010 dollars). Most of this amount
derives from detailed cleanup estimates
developed using damage costs per barrel
measures found in historical spill data
(from all sources including pipeline,
tanker, and shallow water as well as
deepwater wells) and from aggregate
damage measures contained in the legal
settlement documents for past spills
applied to a catastrophic deepwater
spill of hypothetical size. The rest of the
avoided cost amount represents the
private costs for blowout containment
operations. In sum, three components
account for nearly the entire avoided
spill cost total: (1) Natural resource
damage to habitat and creatures, (2)
infrastructure salvage and cleanup
operations of areas soiled by oil, and (3)
containment and well-plugging actions
plus lost hydrocarbons.
The estimate of compliance costs is
somewhat uncertain. This is the case
primarily because the $183 million
annual estimate is perhaps higher than
the actual costs that will be incurred by
society from this rule because industry
is voluntarily undertaking some steps
following the BPDH event that overlap

emcdonald on DSK2BSOYB1PROD with RULES2
Federal Register / Vol. 75, No. 198 / Thursday, October 14, 2010 / Rules and Regulations
those in this regulation. The Joint
Industry Task Force draft
recommendations include use of
mechanical barriers and negative
pressure tests. Voluntary action,
perhaps spurred on as well by revised
liability expectations and increased
insurance prospects, means the
incremental costs associated with these
overlapping measures are not truly
imposed solely by the new regulations.
Less incremental required costs reduce
the improvement in reliability necessary
for expected benefits to cover the cost of
complying with the new regulations. On
the benefit side, the total avoided cost
estimate of $16.3 billion (representing a
measure of expected benefits for
avoiding a future catastrophic oil spill)
is highly uncertain because of the
limited historical data upon which to
judge the cost of failure, the disparity
between the damages associated with
spills of different sizes, locations, and
season of occurrence, and owing to the
fact that the measure employed reflects
only those outlays that we have been
able to calculate based primarily upon
factors derived from past oil spills.
Possible losses from human health
effects or reduced property values have
not been quantified in this analysis.
Moreover, the likelihood of a future
blow out leading to a catastrophic oil
spill is difficult to quantify because of
limited historical data on catastrophic
offshore blowouts.
Benefit-Cost Result: Based on the
occurrence of only a single catastrophic
blowout, the number of GOM deepwater
wells drilled historically (4,123), and
the forecasted future drilling activity in
the GOM (160 deepwater wells per
year), the baseline risk of a catastrophic
blowout is estimated to be about once
every 26 years. Combining the baseline
likelihood of occurrence with the cost of
a hypothetical spill implies that the
expected annualized spill cost is about
$631 million ($16.3 billion once in 26
years, equally likely in any 1 year). To
balance the $183 million annual cost
imposed by these regulations with the
expected benefits, the reliability of the
well control system needs to improve by
about 29 percent ($183 million/$631
million). We have found no studies that
evaluate the degree of actual
improvement that could be expected
from dual mechanical barriers, negative
pressure tests, and a seafloor ROV
function test. We request comment with
supporting evidence on the reliability
improvement likely from these new
provisions.

Regulatory Flexibility Act: Initial
Regulatory Flexibility Analysis
Given the emergency nature of these
rules, BOEMRE has not yet prepared a
detailed Initial Regulatory Flexibility
Analysis for this rule; however,
BOEMRE intends to publish a
supplemental Initial Regulatory
Flexibility Analysis in the near future
which will examine the impact of this
regulation on small entities in greater
detail than provided below. BOEMRE
continues to be interested in all
potential impacts of the interim final
rule on small entities and welcomes
comments on issues related to such
impacts. These comments will assist
BOEMRE in conducting further analysis
than provided below regarding the
economic impact of these regulations on
small entities, as well as an opportunity
to examine regulatory alternatives that
can accomplish BOEMRE’s safety goals
at a lower cost to small entities.
This rulemaking affects lessees,
operators of leases and drilling
contractors on the OCS; thus this rule
directly impacts small entities. This
could include about 130 active Federal
oil and gas lessees and more than a
dozen drilling contractors and their
suppliers. Small entities that operate
under this rule are coded under the
Small Business Administration’s North
American Industry Classification
System (NAICS) codes 211111, Crude
Petroleum and Natural Gas Extraction,
and 213111, Drilling Oil and Gas Wells.
For these NAICS code classifications, a
small company is one with fewer than
500 employees. Based on these criteria,
approximately 70 percent of companies
operating on the OCS (91) are
considered small companies. Therefore,
BOEMRE has determined that this
proposed rule will have an impact on a
substantial number of small entities.
The ownership share of deepwater
leases for small entities is estimated to
only be 12 percent. While a larger
percentage of the oil service industry
supporting the deepwater operators are
small businesses, the lessees that hire
and direct these support businesses will
bear the burden of this rule. Small
PO 00000
Frm 00021
Fmt 4701
Sfmt 4700
63365
companies hold 55 percent of shallow
water leases but a smaller portion of the
costs of these regulations will affect
drilling operations in shallow water.
This rule will affect every new well
on the OCS. Tighter regulatory
standards for drilling operations and the
increased cost of meeting these
requirements as a result of regulations
for extra tests and well standards will
now be required. We estimate that this
rulemaking will impose a recurring cost
of $183 million each year for drilling
OCS wells. Every operator and drilling
contractor both large and small must
meet the same criteria for drilling
operations regardless of company size.
However, the overwhelming share of the
cost imposed by these regulations will
fall on companies drilling deepwater
wells, which are predominately the
larger companies. In fact, 90 percent of
the total costs will be imposed on
deepwater lessees and operators where
small businesses only hold 12 percent of
the leases. Less than 10 percent of the
total costs will apply to shallow water
leases where a 55 percent lease
ownership share is held by small
companies. Furthermore, these
compliance costs only impact drilling
operations. Drilling costs are only a
share of the total costs incurred by a
company operating on the OCS.
Nonetheless, small companies as both
lease-holders, and contractors serving
lease-holders, will bear meaningful
costs under these regulations. Of the
annual $183 million in annual cost
imposed by the rule, we estimate that
the $20 million will apply to small
businesses in deepwater and $9 million
in shallow water. In total we estimate
that $29 million or 15.8 percent of these
regulations’ cost will be borne by small
businesses.
Fiscal year 2009 aggregate annual Gulf
of Mexico OCS oil and gas revenues
were $31.3 billion. Using the same
percentages of leases held as a proxy for
production value in deep and shallow
water, we estimate that 74 percent
($23.3 billion) of the OCS revenues are
ultimately received by large companies
and 26 percent ($8.1 billion) by small
companies. As a share of fiscal year
2009 revenues this interim final rule
would cost approximately 0.67 percent
of OCS revenue for large companies and
only 0.36 ($0.029/$8.1) percent for small
companies.
Even though this rule may not have a
significant economic impact on small
businesses, alternatives to ease impacts
on small business were considered. One
alternative is to exempt small
businesses from the requirements of this
interim final rule. A second alternative
is to delay the implementation timelines

63366

emcdonald on DSK2BSOYB1PROD with RULES2
to comply with the regulation. Both of
these alternatives are being rejected by
BOEMRE for this interim final rule
because of the overriding need to reduce
the chance of a catastrophic blowout
event. We do not believe it is
responsible for a regulator to
compromise the safety of offshore
personnel and the environment for any
entity including small businesses.
Offshore drilling is highly technical and
can be hazardous, any delay may
increase the interim risk of OCS drilling
operations.
Small Business Regulatory Enforcement
Fairness Act
This interim final rule is a major rule
under the Small Business Regulatory
Enforcement Fairness Act (5 U.S.C. 801
et seq.). This interim final rule:
a. Will have an annual effect on the
economy of $100 million or more. This
rule will affect every new well on the
OCS, and every operator, both large and
small must meet the same criteria for
well construction regardless of company
size. This rulemaking may have a
significant economic effect on a
substantial number of small entities and
the impact on small businesses will be
analyzed more thoroughly in an Initial
Regulatory Flexibility Analysis. While
large companies will bear the majority
of these costs, small companies as both
leaseholders and contractors supporting
OCS drilling operations will be affected.
Considering the new requirements for
redundant barriers and new tests, we
estimate that this rulemaking will add
an average of about $1.42 million to
each new deepwater well drilled and
completed with a MODU, $170
thousand for each new deepwater well
drilled with a platform rig, and $90
thousand for each new shallow water
well. While not an insignificant amount,
we note this extra recurring cost is less
than 2 percent of the cost of drilling a
well in deepwater and around 1 percent
for most shallow water wells.
b. Will not cause a major increase in
costs or prices for consumers,
individual industries, Federal, State, or
local government agencies, or
geographic regions. The impact on
domestic deepwater hydrocarbon
production as a result of these
regulations is expected to be negative,
but the size of the impact is not
expected to materially impact the world
oil markets. The deepwater GOM is an
oil province and the domestic crude oil
prices are set by the world oil markets.
Currently there is sufficient spare
capacity in OPEC to offset a decrease in
GOM deepwater production that could
occur as a result of this rule. Therefore,
the increase in the price of hydrocarbon
VerDate Mar<15>2010
17:55 Oct 13, 2010
Jkt 223001
products to consumers from the
increased cost to drill and operate on
the OCS is expected to be minimal.
However, more of the oil for domestic
consumption may be purchased from
overseas markets because the cost of
OCS oil and gas production will rise
relative to other sources of supply. This
shift would contribute negatively to our
balance of trade.
c. Will not have significant adverse
effects on competition, innovation, or
the ability of U.S.-based enterprises to
compete with foreign-based enterprises.
d. May have adverse effects on
employment, investment, and
productivity. A meaningful increase in
costs as a result of more stringent
regulations and increased drilling costs
may result in a reduction in the pace of
deepwater drilling activity on marginal
offshore fields, and reduce investment
in our domestic energy resources from
what it otherwise would be, thereby
reducing employment in OCS and
related support industries. The
additional regulatory requirements in
this rulemaking will increase drilling
costs and add to the time it takes to drill
deepwater wells. The resulting
reduction in profitability of drilling
operations may cause some declines in
related investment and employment. A
typical deepwater well drilled by a
MODU may cost $90–$100 million. The
added cost of these regulations for a
deepwater well is expected to be about
$1.42 million; this is less than a 2
percent decrease in productivity for
drilling a deepwater well as a result of
these regulations.
e. Accommodations for small business
have not been made to avoid the risk of
compromising the safety and
environmental protections addressed in
this rulemaking. Small businesses
actively invest in offshore operations,
owning a 12 percent interest in
deepwater leases, most often as a
minority partner. These regulations will
make it more expensive for all interest
holders in OCS leases, and we do not
expect a disproportionate impact on
small businesses. However, we
anticipate that the costs in this rule may
contribute to one or more of the
following:
1. Reduce the small business
ownership share in individual
deepwater leases.
2. Cause small businesses to target
their investments more in shallow water
leases.
3. Cause small businesses to target
their investments more in onshore oil
and gas operations or other natural
resources.

Frm 00022
Fmt 4701
Sfmt 4700
4. Small businesses may choose to
invest or partner in overseas natural
resource operations.
f. There are many small businesses
that support offshore oil and gas drilling
operations including service, supply,
and consulting companies. They will
also be affected by this rule. Because we
can reasonably anticipate an overall
decrease in deepwater drilling activity
due to the increased cost and regulatory
burden, some businesses that support
drilling operations may experience
reduced business activity. Some small
businesses may therefore decide to
focus more on shallow water or other oil
and gas offshore provinces overseas.
g. There are some small businesses
that may benefit from this rulemaking.
Companies that are involved with
inspecting and certifying this
equipment, as well as consulting
companies specializing in safety and
offshore drilling, could see long-term
growth.
Unfunded Mandates Reform Act of 1995
This rule will impose an unfunded

As discussed earlier in the preamble,
this interim final rulemaking is a
revision to various sections of the 30
CFR part 250 regulations that will
amend drilling regulations in subparts
D, E, F, O, and Q. This includes
requirements that will implement
various safety measures that pertain to
drilling operations. The information
collected will ensure sufficient
redundancy in the BOPs; promote the
integrity of the well and enhance well
control; and facilitate a culture of safety
through operational and personnel
management. This rule will promote
human safety and environmental
protection.
Under § 250.198, this section lists all
of the documents incorporated by
reference in the 30 CFR part 250
regulations. This rulemaking revises this
section to include the new 30 CFR part
250 document we are incorporating and
the document already incorporated that
we are updating. Under the PRA (5 CFR
part 1320), information and
recordkeeping produced during
customary and usual business activities
are excluded from agency IC burdens.
Information submitted or reported to the
Federal Government that goes beyond
these practices does count as burdens
and is required to have OMB approval
under the PRA. We consider all of the
activities and operations performed in
accordance with the documents
incorporated by reference involved in
this rulemaking to be customary and
usual business activities because they
are consensus standards developed by
working task force groups. These groups
are comprised of subject matter experts
from the industry and government in
the following fields: Blowout preventer
equipment, cementing, and well design.
Any information and recordkeeping
produced during the conduct of
operations or activities performed under
those standards, therefore, do not count
as new or additional IC burdens.
The rulemaking clarifies
requirements, but does not change the
hour burdens in 30 CFR part 250,
subpart O (1010–0128, expiration 11/30/
2012). This rulemaking also references,
but does not change, the requirements

and burdens in 30 CFR part 250, subpart
Q (1010–0142, expiration 11/30/2010).
However, the rule does change and add
new requirements to those already
approved for 30 CFR part 250, subparts
D, E, and F, as explained in the
following paragraphs.
The current regulations on Oil and
Gas Drilling Operations and associated
IC are located in 30 CFR part 250,
subpart D. The OMB approved the IC
burden of the current subpart D
regulations under control number 1010–
0141 (expiration 11/30/2011). This
interim final rule expands the current
regulatory requirements and adds new
requirements that pertain to subsea and
surface BOPs, well casing and
cementing, secondary intervention,
unplanned disconnects, recordkeeping,
well completion, and well plugging
(+24,144 burden hours).
The current regulations on Oil and
Gas Well-Completion Operations and
associated IC are located in 30 CFR part
250, subpart E. The OMB approved the
IC burden of the current subpart E
regulations under control number 1010–
0067 (expiration 12/31/2010). This
interim final rule adds new regulatory
requirements to this subpart that pertain
to subsea and surface BOPs, secondary
intervention, and well-completions
(+4,669 burden hours).
The current regulations on Oil and
Gas Well-Workover Operations and
associated IC are located in 30 CFR part
250, subpart F. The OMB approved the
IC burden of the current subpart F
regulations under control number 1010–
0043 (expiration 12/31/2010). This
interim final rule adds new regulatory
requirements to this subpart that pertain
to subsea and surface BOPs, secondary
intervention, unplanned disconnects,
and well-workers (+15,918 burden
hours).
When this rulemaking becomes
effective, the additional 30 CFR part
250, subparts D, E, and F paperwork
burdens will be incorporated into their
respective primary collections; 1010–
0141, 1010–0067, and 1010–0043,
respectively.

National Environmental Policy Act of
1969
We have prepared an environmental
assessment to determine whether this
rule will have a significant impact on
the quality of the human environment
under the National Environmental
Policy Act of 1969. This rule does not
constitute a major Federal action
significantly affecting the quality of the
human environment. A detailed
statement under the National
Environmental Policy Act of 1969 is not
required because we reached a Finding
of No Significant Impact. A copy of the
Environmental Assessment can be
viewed at https://www.Regulations.gov

Data Quality Act
In developing this rule, we did not
conduct or use a study, experiment, or
survey requiring peer review under the

C § 515, 114 Stat. 2763, 2763A–153–
154).
emcdonald on DSK2BSOYB1PROD with RULES2
Effects on the Energy Supply (E.O.
13211)
This rule is a significant rule and is
subject to review by the Office of
Management and Budget under E.O.
12866. The rule does have an effect on
energy supply, distribution, or use
because its provisions may delay
development of some OCS oil and gas
resources. The delay stems from the
extra drill time and cost imposed on
new wells which will somewhat slow
exploration and development
operations. We estimate an average
delay of 2 days and cost of $1.42 million
for most deepwater wells in the GOM.
Increased imports or inventory
drawdowns should compensate for most
of the delay or reduction in domestic
production. The recurring costs
imposed on new drilling by this rule are
very small (2 percent) relative to the
cost of drilling a well in deepwater. In
view of the high risk-reward associated
with deepwater exploration in general,
we do not expect this small regulatory
surcharge from this rule to result in
meaningful reduction in discoveries.
Thus, we expect the net change in
supply associated with this rule will
cause only a slight increase in oil and
gas prices relative to what they
otherwise would have been. Normal
volatility in both oil and gas market
prices overshadow these rule related
price effects, so we consider this an
insignificant effect on energy supply
and price.
Clarity of This Regulation
We are required by E.O. 12866, E.O.
12988, and by the Presidential
Memorandum of June 1, 1998, to write
all rules in plain language. This means
that each rule we publish must:
a. Be logically organized;
b. Use the active voice to address
readers directly;
c. Use clear language rather than
jargon;
d. Be divided into short sections and
sentences; and
e. Use lists and tables wherever
possible.
If you feel that we have not met these
requirements, send us comments by one
of the methods listed in the ADDRESSES
section. To better help us revise the
VerDate Mar<15>2010
17:55 Oct 13, 2010
Jkt 223001
rule, your comments should be as
specific as possible. For example, you
should tell us the numbers of the
sections or paragraphs that you find
unclear, which sections or sentences are
too long, the sections where you feel
lists or tables would be useful, etc.
Public Availability of Comments
Before including your address, phone
number, email address, or other
personal identifying information in your
comment, you should be aware that
your entire comment—including your
personal identifying information—may
be made publicly available at any time.
While you can ask us in your comment
to withhold your personal identifying
information from public review, we
cannot guarantee that we will be able to
do so.
Appendix A
BOEMRE Response to the Deepwater
Horizon Event and Resulting Oil Spill
I. Description
On April 20, 2010, the crew of the
Transocean drilling rig Deepwater Horizon
was preparing to temporarily abandon BP’s
discovery well at the Macondo prospect, 52
miles from shore in 4,992 feet of water in the
GOM. An explosion and subsequent fire on
the rig caused 11 fatalities and several
injuries. The rig sank 2 days later, resulting
in an uncontrolled release of oil that was
declared a spill of national significance.
II. Status of BOEMRE/USCG Joint
Investigation
The DOI and USCG are undertaking a joint
investigation into the causes of the
explosions and fire on the Deepwater
Horizon. This joint investigation includes
members of BOEMRE and the USCG and
involves issuing subpoenas for documents
and testimony, obtaining expert analyses of
data and reports, holding public hearings,
calling witnesses, and taking any other steps
necessary to determine the cause of the spill.
The purpose of this joint investigation is to
develop conclusions about the cause and
recommendations for preventing a similar
event. The facts collected at the public
hearings, along with the lead investigators’
conclusions and recommendations, will be
forwarded to USCG Headquarters and
BOEMRE for approval. Once approved, the
final investigative report will be made
available to the public and the media. The
team has been given 9 months, from the date
of the convening order (April 27, 2010), to
submit the final report.
III. DOI and BOEMRE actions
In response to the Deepwater Horizon
event, DOI and BOEMRE have taken several
actions, as outlined below. Numerous other
investigations and reviews have been
commenced, including an investigation by
the DOI Safety Oversight Board; an
investigation by the President’s National
Commission on the BP Deepwater Horizon
Oil Spill and Offshore Drilling; the USCG
PO 00000
Frm 00026

incident Specific Preparedness Review; a
review by the National Academy of
Engineering; a review by the U.S. Chemical
Safety Board; and others. This Appendix
addresses only BOEMRE actions. These are
as follows:
1. Issued a Joint Safety Alert with USCG on
April 30, 2010.
2. Published the Safety Measures Report on
May 27, 2010, at the request of the President.
3. Issued National NTL No. 2010–N05,
‘‘Increased Safety Measures for Energy
Development on the OCS,’’ to implement the
immediate recommendations from the Safety
Measures Report.
4. Issued National NTL No. 2010–N06,
‘‘Information Requirements for Exploration
Plans, Development and Production Plans,
and Development Operations Coordination
Documents on the OCS.’’
5. Implemented Secretarial Decision dated
July 12, 2010, ordering the suspensions of
drilling activities that use a subsea BOP stack
and drilling from floating facilities with a
surface BOP stack.
6. Held public meetings to collect
information and views about deepwater
drilling safety reforms, blowout containment,
and oil spill response.
1. Joint USCG–BOEMRE Safety Alert
On April 30, 2010, USCG and BOEMRE
issued a National Safety Alert No. 2
concerning the Deepwater Horizon event and
resulting oil spill. BOEMRE and the USCG
included the following safety
recommendations to operators and drilling
contractors:
(1) Examine all well control equipment
(both surface and subsea) currently being
used to ensure that it has been properly
maintained and is capable of shutting in the
well during emergency operations. Ensure
that the ROV hot-stabs are function-tested
and are capable of actuating the BOP.
(2) Review all rig drilling/casing/
completion practices to ensure that well
control contingencies are not compromised at
any point while the BOP is installed on the
wellhead.
(3) Review all emergency shutdown and
dynamic positioning procedures that
interface with emergency well control
operations.
(4) Inspect lifesaving and firefighting
equipment for compliance with Federal
requirements.
(5) Ensure that all crew members are
familiar with emergency/firefighting
equipment, as well as participate in an
abandon ship drill. Operators are reminded
that the review of emergency equipment and
drills should be conducted after each crew
change out.
(6) Exercise emergency power equipment
to ensure proper operation.
(7) Ensure that all personnel involved in
well operations are properly trained and
capable of performing their tasks under both
normal drilling and emergency well control
operations.
2. Safety Measures Report
a. Summary
On April 30, 2010, the President ordered
the Secretary of the Interior to conduct a
E:\FR\FM\14OCR2.SGM
14OCR2
emcdonald on DSK2BSOYB1PROD with RULES2
Federal Register / Vol. 75, No. 198 / Thursday, October 14, 2010 / Rules and Regulations
thorough review of this event and to report,
within 30 days, on what, if any, additional
precautions and technologies should be
required to improve the safety of oil and gas
exploration and production operations on the
OCS. The Safety Measures Report was
presented to the President on May 27, 2010.
A copy of the report is available at: https://
www.doi.gov/news/pressreleases/
loader.cfm?csModule=security/
getfile&PageID=33646.
The Safety Measures Report was developed
without the benefit of the findings from the
ongoing investigations into the root causes of
the explosions and fire on the Deepwater
Horizon and the resulting oil spill. In the
coming months, those investigations will
likely suggest refinements to some of this
report’s recommendations, as well as
additional safety measures.
The Safety Measures Report includes a
history of OCS production, spills, and
blowouts; a review of the existing U.S.
regulatory and enforcement structure; a
survey of other countries’ regulatory
approaches; and a summary of existing
BOEMRE-sponsored studies on technologies
that could reduce the risk of blowouts. The
report examines all aspects of drilling
operations, including equipment, procedures,
personnel management, and inspections and
verification in an effort to identify safety and
environmental protection measures that
would reduce the risk of a catastrophic event.
In particular, this report examines several
issues highlighted by the Deepwater Horizon
event regarding operational and personnel
safety while conducting drilling operations
in deepwater environments.
The Safety Measures Report includes a
number of recommendations to improve the
safety of oil and gas drilling operations on
the OCS. These recommendations address:
• Well-control and well abandonment
operations;
• Specific requirements for devices, such
as BOPs and their testing;
• Industry practices;
• Worker training;
• Inspection protocol and operator
oversight; and
• The responsibility of the Department for
safety and enforcement.
The draft recommendations were peer
reviewed by seven experts identified by the
National Academy of Engineering.
b. Implementation teams. To inform the
efforts related to implementation of some of
the recommendations from the Safety
Measures Report, the DOI Safety Oversight
Board Report, the recommendations to be
developed by the President’s bipartisan
National Commission and other investigative
and reviewing bodies, DOI is establishing
Department-led implementation teams. These
teams, initially described as ‘‘strike teams’’ in
the Safety Measures Report, will evaluate
various issues, both highly technical and
non-technical.
The implementation teams will seek input
as appropriate from academia, industry, and
other technical experts and stakeholders.
They will develop and present their
recommendations for further actions to
address additional environmental protection
and safety measures. The Department may
VerDate Mar<15>2010
17:55 Oct 13, 2010
Jkt 223001
use the recommendations from these
implementation teams to:
(1) Inform future rulemaking,
(2) Develop internal policy for inspections
and enforcement of regulations,
(3) Identify future research needs.
3. NTL No. 2010–N05—Increased Safety
Measures for Energy Development on the
OCS
The NTL No. 2010–N05, ‘‘Increased Safety
Measures for Energy Development on the
OCS,’’ addressed the recommendations from
the Safety Measures Report that warranted
immediate implementation. The link to this
NTL is: https://www.gomr.boemre.gov/
homepg/regulate/regs/ntls/2010NTLs/10n05.pdf.
BOEMRE issued this NTL on June 8, 2010,
as a result of the Deepwater Horizon event.
The NTL addresses the recommendations in
the report to the President entitled,
‘‘Increased Safety Measures for Energy
Development on the Outer Continental Shelf’’
dated May 27, 2010, and details under thenexisting regulations the requirements lessees
and operators must meet to operate on the
OCS. Following are the specific items
included in the NTL:
Operators are required to:
• Verify compliance with existing
regulations and Safety Alert issued on April
30, 2010.
• Submit BOP and well control system
configuration information for the drilling rig
that was being used.
• Recertify all BOP equipment before
resuming drilling.
• Have documentation showing that the
BOP has been maintained according to the
regulations at 30 CFR 250.446(a). The
operators are required to maintain records
and make them available upon request.
• Obtain independent third party
verification that the BOP stack is designed for
the specific equipment on the rig and
compatible with the specific well location,
well design, and well execution plan; the
BOP stack has not been compromised or
damaged from previous service; and the BOP
stack will operate in the conditions in which
it will be used.
• Have a secondary control system with
ROV intervention capabilities, including the
ability to close one set of blind-shear rams
and one set of pipe rams and unlatch the
LMRP.
• Have an emergency shut-in system in the
event that you lose power to the BOP stack,
have an unplanned disconnection of the riser
from the BOP stack, or experience another
emergency situation.
• Function test the hot stabs that would be
used to interface with the ROV intervention
panel during the stump test.
• Obtain an independent third party
verification that provides sufficient
information showing that the blind-shear
rams installed in the BOP stack are capable
of shearing the drill pipe in the hole under
maximum anticipated surface pressures.
• If the blind-shear rams or casing shear
rams are activated in a well control situation
in which pipe or casing was sheared,
operators must inspect and test the BOP stack
and its components, after the situation is
fully controlled.

• Have all well casing designs and
cementing program/procedures certified by a
Professional Engineer, verifying the casing
design is appropriate for the purpose for
which it is intended under expected wellbore
conditions.
• Submit the relevant information
discussed in the NTL prior to commencing
those operations, and drilling may not
commence without BOEMRE approval.

Requirements for Exploration Plans,
Development and Production Plans, and
Development Operations Coordination
Documents on the OCS
The link to this NTL is: https://
www.gomr.boemre.gov/homepg/regulate/
regs/ntls/2010NTLs/10-n06.pdf.
BOEMRE issued this NTL on June 18,
2010. This NTL provides guidance to lessees
and operators regarding the blowout and oil
spill information required in the exploration
and development plan documents submitted
to BOEMRE, including:
A blowout scenario as required by 30 CFR
250.213(g) and 250.243(h), including:
Highest volume of liquid hydrocarbons;
Estimated flow rate, total volume, and
maximum duration;
Potential for the well to bridge over;
Likelihood for surface intervention to stop
the blowout;
Availability of a rig to drill a relief well;
Time frame to drill a relief well.
A description of the assumptions and
calculations used to determine the volume of
the worst case discharge scenario, including:
Well design;
Reservoir characteristics;
Fluid characteristics;
Pressure, volume, and temperature
characteristics;
Analog reservoir assumptions;
Supporting calculations and models used
in determining worst case scenario.
5. Secretarial Decision Suspending Drilling
Activities That Use Subsea BOP Stacks and
Drilling From Floating Facilities With a
Surface BOP Stack
On July 12, 2010, the Secretary issued a
decision directing BOEMRE to suspend the
drilling of wells using subsea BOPs or surface
BOPs on floating facilities, and to cease
approval of pending and future applications
for permits to drill using subsea BOPs or
surface BOPs on floating facilities. These
directives apply in the GOM and Pacific
regions through November 30, 2010, subject
to modification if the Secretary determines
that the significant threats to life, property,
and the environment set forth in his decision
have been sufficiently addressed. This
includes additional information about the
causes of the Deepwater Horizon Oil Spill.
Several investigations and reviews are being
undertaken to identify the root causes of the
disaster, including a joint BOEMRE–USCG
investigation, a review by the NAE, on-going
Congressional inquiries, and the National
Commission on the BP Deepwater Horizon
Oil Spill and Offshore Drilling (Presidential
Commission). The results of these will better
inform DOI decision-making and longer-term
rulemaking.
Following this decision, on July 12, 2010,
BOEMRE issued suspension orders of most

deepwater drilling operations on the OCS
through November 30, 2010. BOEMRE
stopped approval of pending and future
deepwater drilling applications in the GOM
and Pacific regions.
6. Held Public Meetings to Collect
Information and Views About Deepwater
Drilling Safety Reforms, Blowout
Containment, and Oil Spill Response
As directed by the Secretary in the
Decision of July 12, 2010, the BOEMRE
Director led a series of public meetings to
collect information and views about
deepwater drilling safety reforms, blowout
containment, and oil spill response. The
Director solicited input from the general
public, state, and local leaders, experts from
academia, the environmental community,
and the oil and gas industry. The link to the
Public Forums on Offshore Drilling is:
https://www.boemre.gov/forums/. The
webpage provides information and
presentations from each meeting. The
meetings were held in August and September
in the following cities: New Orleans,
Louisiana; Mobile, Alabama; Pensacola,
Florida; Santa Barbara, California;
Anchorage, Alaska; Houston, Texas; Biloxi,
Mississippi; Lafayette, Louisiana.

ACTION: Interim final rule with request for comments.
-----------------------------------------------------------------------
SUMMARY: This interim final rule implements certain safety measures
recommended in the report entitled, ``Increased Safety Measures for
Energy Development on the Outer Continental Shelf'' (Safety Measures
Report), dated May 27, 2010. The President directed the Department of
the Interior to develop the Safety Measures Report to identify measures
necessary to improve the safety of oil and gas exploration and
development on the Outer Continental Shelf in light of the Deepwater
Horizon event on April 20, 2010, and resulting oil spill. To implement
the practices recommended in the Safety Measures Report, the Bureau of
Ocean Energy Management, Regulation and Enforcement is amending
drilling regulations related to well control, including: subsea and
surface blowout preventers, well casing and cementing, secondary
intervention, unplanned disconnects, recordkeeping, well completion,
and well plugging.
DATES: Effective Date: This rule becomes effective on October 14, 2010.
The incorporation by reference of the publication listed in the
regulations is approved by the Director of the Federal Register as of
October 14, 2010. Submit comments on the interim final rule by December
13, 2010. BOEMRE may not fully consider comments received after this

I. Background
This interim final rule promulgated for the prevention of waste and
conservation of natural resources of the Outer Continental Shelf,
establishes regulations based on certain recommendations in the May 27,
2010, report from the Secretary of the Interior to the President
entitled, ``Increased Safety Measures for Energy Development on the
Outer Continental Shelf'' (Safety Measures Report). The President
directed that the Department of the Interior (DOI) develop this report
as a result of the Deepwater Horizon event on April 20, 2010. This
event, which involved a blowout of the BP Macondo well and an explosion
on the Transocean Deepwater Horizon mobile offshore drilling unit
(MODU), resulted in the deaths of 11 workers, an oil spill of national
significance, and the sinking of the Deepwater Horizon MODU. On June 2,
2010, the Secretary of the Interior directed the Bureau of Ocean Energy
Management, Regulation and Enforcement (BOEMRE) (formerly the Minerals
Management Service) to adopt the recommendations contained in the
Safety Measures Report and to implement them as soon as possible.
The Safety Measures Report recommended a series of steps to improve
the safety of offshore oil and gas drilling operations in Federal
waters. It outlined a number of specific measures designed to ensure
sufficient redundancy in blowout preventers (BOPs), promote well
integrity, enhance well control, and facilitate a culture of safety
through operational and personnel management.
The Safety Measures Report recommended that certain measures be
implemented immediately through a Notice to Lessees and Operators
(NTL). It identified other measures as being appropriate to address
through an emergency rulemaking process. The Safety Measures Report
recognized that other recommendations would require additional review
and refinement through technical reviews by the DOI, through
information supplied as a result of the numerous investigations into
the root causes of the Deepwater Horizon explosion, and through the
longer-term recommendations of DOI strike teams and inter-agency work
groups. The Safety Measures Report recommended that these other
measures be addressed through notice and comment rulemaking, as
appropriate.
On June 8, 2010, BOEMRE issued an NTL addressing those
recommendations identified in the Safety Measures Report as warranting
immediate implementation (NTL No. 2010-N05--Increased Safety Measures
for Energy Development on the OCS). This interim final rule clarifies
existing regulatory requirements that were addressed by certain
portions of NTL No. 2010-N05. This rule incorporates specific details
included in 2010-N05 by codifying these into regulations. The rule does
not codify the one-time requirements from NTL No. 2010-N05, such as the
one-time requirement for recertification of all BOP equipment used in
new floating operations, which will be evaluated and considered for
future rulemakings as appropriate.
This interim final rule also addresses measures identified in the
Safety Measures Report as appropriate for
[[Page 63347]]
implementation through emergency rulemaking, with certain exceptions
discussed later. It also includes other provisions from the Safety
Measures Report that BOEMRE considers appropriate for immediate
implementation in this interim final rule.
As provided for in the Safety Measures Report, BOEMRE will continue
to review other safety measures. These include items that may be
appropriate for rulemaking in the near future, as well as measures that
will require further study, whether through DOI-led strike teams,
inter-agency workgroups, or other means.
The following table provides a summary of the interim final rule
requirements, estimated annual costs to implement the requirements, and
the operator's ability to comply with the requirements. Additional
discussion on all the requirements follows in the remainder of the
preamble.

* DOI estimated the cost of a hypothetical spill in the future at $16.3
billion, and also estimated the baseline likelihood of a catastrophic
blowout event and spill occurring, based on historical trends and the
number of expected future wells, to be once every 26 years. These
estimates are necessarily uncertain, and are discussed in more detail
in the RIA. Combining the baseline likelihood of occurrence with the
cost of a hypothetical spill implies that the expected annualized
spill cost is about $631 million. This rulemaking will not reduce the
probability of a future spill to zero; therefore, ``B'' in the table
above represents the adjustment in annual avoided social costs
expected from this rulemaking based on the non-zero remaining
probability of a spill after this rule is put into place. Thus, the
difference between the avoided costs with and without their rule
represents its expected benefits. This remaining probability is
uncertain. For example, to balance the $183 million annual cost
imposed by these regulations with the expected benefits, the
reliability of the well control system needs to improve by about 29
percent ($183 million/$631 million). Although we have found no studies
that evaluate the degree of actual improvement that could be expected
from dual mechanical barriers, negative pressure tests, and a seafloor
ROV function test, we believe it reasonable to anticipate that such
measures will increase the reliability of the well control systems,
and therefore that the benefits of this rulemaking justify the costs.
II. Request for Comments on Interim Final Rule and Effective Date
This is an interim final rulemaking with request for comments; it
is effective immediately upon publication. The Administrative Procedure
Act (APA) requires that an agency publish a proposed rule in the
Federal Register with notice and an opportunity for public comment,
unless the agency, for good cause, finds that providing notice and
soliciting comments in advance of promulgating the rule would be
impracticable, unnecessary, or contrary to the public interest (5
U.S.C. 553(b)). BOEMRE determined that there is good cause for
publishing this interim final rule without prior notice and comment
based on its findings, consistent with preliminary information that is
available as a result of investigations into the Deepwater Horizon
event, that certain equipment, systems, and improved practices are
immediately necessary for the safety of offshore oil and gas drilling
operations on the Outer Continental Shelf (OCS), and that these
improved drilling practices are either not addressed or not
sufficiently detailed by current regulations. Immediate imposition of
the requirements contained in this interim final rule is necessary
because BOEMRE views strict adherence to improved safety practices set
forth herein as necessary to achieving safer conditions that, together
with other wild well control and oil spill response capabilities, will
allow it to permit future OCS drilling operations. Following notice and
comment procedures would be impracticable in these circumstances.
Furthermore, following notice and comment procedures would be
contrary to the public interest because the delay in implementation of
this interim final rule could result in harm to public safety and the
environment. Failure to adhere to the safety practices required by this
interim final rule increases the risk of a blowout and subsequent oil
spill, with serious consequences to the health and safety of workers
and the environment.
As discussed in Section 5, ``Justification for the Interim Final
Rulemaking,'' while investigation and information-gathering into the
Deepwater Horizon blowout and spill continues, preliminary evidence
suggests problems with the Macondo well's line of defense, which could
include blowout preventer (BOP) systems, casing and cementing programs,
and fluid displacement procedures. Evidence further suggests that it is
unlikely that these problems are unique to the Deepwater Horizon event;
for example, most BOPs used in drilling on the OCS are of similar
design and are produced by a limited number of manufacturers. The
interim final rule's provisions thus incorporate targeted measures to
promote the integrity of the well and enhance well control, including
provisions specifically identified by the Safety Measures Report as
warranting immediate implementation. For example, the requirement that
operators have all well casing designs and cementing systems/procedures
certified by a Professional Engineer.
Similarly, BOEMRE determined that the immediate necessity for
improved equipment, systems, and practices also provides good cause to
impose an immediate effective date. The APA requires an agency to
publish a rule not less than 30 days before its effective
[[Page 63351]]
date, except as otherwise provided by the agency for good cause found
and published with the rule (5 U.S.C. 553(d)(3)). Just as BOEMRE found
that providing notice and an opportunity to comment is impracticable
and contrary to the public interest, BOEMRE finds that a 30-day delay
after publication of this interim final rule compromises the safety of
offshore oil and gas drilling. To the extent that the 30-day period is
intended to allow regulated parties to adjust to new requirements,
information gathered by BOEMRE in advance of this rulemaking indicates
that the oil and gas industry is well aware of the general provisions
in this interim final rule. Most of the provisions in the rule were
identified in the Safety Measures Report, and industry is already
working to implement them.
We note that in developing the Safety Measures Report on which this
interim final rule is based, the Department consulted with a wide range
of experts in state and Federal governments, academic institutions, and
industry and advocacy organizations. In addition, the draft
recommendations of the Safety Measure Report were peer reviewed by
seven experts identified by the National Academy of Engineering (NAE).
Further explanation of the justification for this interim final
rulemaking is provided in section V, ``Justification for Interim Final
Rulemaking.''
While BOEMRE will not solicit comments before the effective date,
BOEMRE will accept and consider public comments on this rule that are
submitted within 60 days of its publication in the Federal Register.
After reviewing the public comments, BOEMRE will publish a notice in
the Federal Register that will respond to comments and will either:
1. Confirm this rule as a final rule with no additional changes, or
2. Issue a revised final rule with modifications, based on public
comments.
III. Overview of Requirements in the Interim Final Rule
As recommended in the Safety Measures Report, this interim final
rule imposes a number of prescriptive, near-term requirements. Other
longer-term safety measures and performance-based standards recommended
in the Safety Measures Report will be analyzed for implementation in
future rulemakings. Information from the many investigations and other
information sources will also be analyzed and considered in future
rulemakings. In developing the Safety Measures Report on which this
interim final rule is based, the Department consulted with experts in
state and Federal government, academic institutions, and industry and
advocacy organizations. In addition, draft recommendations were peer
reviewed by seven experts identified by the NAE.
The primary purpose of this interim final rule is to clarify and
incorporate safeguards that will decrease the likelihood of a blowout
during drilling operations on the OCS. The safeguards address well bore
integrity and well control equipment, and this interim final rule
focuses on those two overarching issues. This rule will therefore
promulgate OCS-wide provisions that will:
1. Establish new casing installation requirements,
2. Establish new cementing requirements (incorporate American
Petroleum Institute (API) Recommended Practice (RP) 65--Part 2,
Isolating Potential Flow Zones During Well Construction),
3. Require independent third party verification of blind-shear ram
capability,
4. Require independent third party verification of subsea BOP stack
compatibility,
5. Require new casing and cementing integrity tests,
6. Establish new requirements for subsea secondary BOP
intervention,
7. Require function testing for subsea secondary BOP intervention,
8. Require documentation for BOP inspections and maintenance,
9. Require a Registered Professional Engineer to certify casing and
cementing requirements, and
10. Establish new requirements for specific well control training
to include deepwater operations.
As stated, the intent of this interim final rule is to improve
safety related to both well bore integrity and well control equipment.
Well bore integrity provides the first line of defense against a
blowout by preventing a loss of well control. Well bore integrity
includes appropriate use of drilling fluids and the casing and
cementing program. Drilling fluids and the casing and cementing program
are used to balance the pressure in the borehole against the fluid
pressure of the formation, preventing an uncontrolled influx of fluid
into the wellbore. The specific provisions in this rule that address
well bore integrity are:
1. Incorporating by reference API RP 65--Part 2, Isolating
Potential Flow Zones During Well Construction;
2. Submission of certification by a Registered Professional
Engineer that the casing and cementing program is appropriate for the
purpose for which it is intended under expected wellbore pressure;
3. Requirements for two independent test barriers across each flow
path during well completion activities (also certified by a Registered
Professional Engineer);
4. Ensuring proper installation of the casing or liner in the
subsea wellhead or liner hanger;
5. Approval from the District Manager before displacing kill-weight
drilling fluid; and
6. Deepwater well control training for rig personnel.
Well control equipment is the general term for the technologies
used to control a well by mechanical means in the event that other well
control mechanisms fail. Well control equipment includes control
systems that activate the BOPs, either through a control panel on the
drilling rig or through Remotely Operated Vehicles (ROVs) that directly
interface with the subsea BOP to activate the appropriate rams. The
provisions in this rule that address well control equipment include:
1. Submission of documentation and schematics for all control
systems;
2. A requirement for independent third party verification that the
blind-shear rams are capable of cutting any drill pipe in the hole
under maximum anticipated surface pressure (MASP);
3. A requirement for a subsea BOP stack equipped with ROV
intervention capability. At a minimum, the ROV must be capable of
closing one set of pipe rams, closing one set of blind-shear rams, and
unlatching the Lower Marine Riser Package (LMRP);
4. A requirement for maintaining an ROV and having a trained ROV
crew on each floating drilling rig on a continuous basis;
5. A requirement for autoshear and deadman systems for dynamically
positioned rigs;
6. Establishment of minimum requirements for personnel authorized
to operate critical BOP equipment;
7. A requirement for documentation of subsea BOP inspections and
maintenance according to API RP 53, Recommended Practices for Blowout
Prevention Equipment Systems for Drilling Wells;
8. Required testing of all ROV intervention functions on the subsea
BOP stack during the stump test and testing at least one set of rams
during the initial test on the seafloor;
9. Required function testing of autoshear and deadman systems on
the subsea BOP stack during the stump test and testing the deadman
system during the initial test on the seafloor; and
[[Page 63352]]
10. Required pressure testing if any shear rams are used in an
emergency.

IV. Source of Specific Provisions Addressed in the Interim Final Rule
This interim final rule clarifies existing regulatory requirements
that were addressed by certain portions of NTL No. 2010-N05 by
codifying the specific details into regulations. It also addresses
items in the Safety Measures Report either identified as appropriate
for implementation through emergency rulemaking, or which BOEMRE has
determined will significantly increase OCS drilling safety and with
which operators can readily comply. The following provides an
explanation of each of these sources and provisions.
Emergency Rulemaking Recommendations From Safety Measures Report
The Safety Measures Report identified four items for emergency
rulemaking:
1. Develop secondary control system requirements;
[[Page 63353]]
2. Establish new blind-shear ram redundancy requirements;
3. Establish new deepwater well control procedure requirements; and
4. Adopt safety case requirements for floating drilling operations
on the OCS.
Of these four items, this interim final rule addresses: 1.
Secondary control system requirements; and 3. deepwater well control
procedure requirements. This interim final rule does not include: 2.
New blind-shear ram redundancy requirements; and 4. safety case
requirements for floating drilling operations on the OCS.
BOEMRE determined that, while new blind-shear ram redundancy
requirements are important to offshore drilling safety, they are not
appropriate for inclusion in this interim final rule. Installation of a
second set of blind-shear rams will require major modifications to the
BOP stack for most rigs on the OCS. Compliance with such a requirement
is likely to take operators from 1 year to 18 months. Inclusion of a
requirement that will necessitate a period of 1 year or more to comply
is not appropriate for an interim final rule, the purpose of which is
to have immediate effect. Given the necessary compliance periods,
BOEMRE believes there will be sufficient opportunity to proceed through
a notice and comment rulemaking. Operators should be aware, however,
that BOEMRE intends to promptly initiate a notice and comment
rulemaking process to address this issue. Specifically, operators
should be aware that BOEMRE is considering regulations to require the
installation of a second set of blind-shear rams, appropriately spaced
to ensure that at least one blind-shear ram cuts any drill pipe in the
hole and seals the wellbore at any time. Operators should also be aware
that BOEMRE is likewise considering requiring, through a notice and
comment rulemaking, a set of casing shear rams capable of shearing any
casing in the hole.
This interim final rule addresses both new well bore integrity
requirements and well control equipment requirements. The well bore
integrity provisions impose requirements for casing and cementing
design and installation, tighter cementing practices, the displacement
of kill-weight fluids, and testing of independent well barriers. These
new requirements ensure that there are additional physical barriers in
the well to prevent oil and gas from escaping into the environment.
These new requirements related to well bore integrity will considerably
decrease the likelihood of a loss of well control. The well control
equipment requirements in this interim final rule will help ensure the
BOPs will operate in the event of an emergency and that the ROVs are
capable of activating the BOPs. Together, these new requirements will
help decrease the urgency of immediately requiring blind-shear ram
redundancy on BOPs, and have factored into BOEMRE's decision to address
such requirements through a standard rulemaking process.
BOEMRE also determined not to include safety case requirements for
floating drilling operations in this interim final rule. A safety case
is a comprehensive, structured documentation system to reduce operating
risks for offshore drilling. A drilling safety case would establish
risk assessment and mitigation processes to manage a drilling
contractor's controls related to health, safety, and environmental
aspects of operations. BOEMRE is evaluating how a drilling safety case
should be most appropriately integrated with an overall Safety and
Environmental Management System (SEMS) approach, which BOEMRE may
implement through a separate rulemaking process. As directed in the
Safety Measures Report, BOEMRE will work with offshore operators and
drilling contractors, appropriate government agencies, and other
appropriate stakeholders to consider the type of well construction
interfacing document that will best connect the requirements of a
safety case to existing well design and construction documents. BOEMRE
therefore intends to pursue adoption of appropriate safety case
requirements through a separate rulemaking process once the necessary
analyses have been completed.

This provision is recommended in the Safety Measures Report,
although it is not specifically identified as requiring implementation
immediately or through emergency rulemaking (this provision was also
not addressed in NTL No. 2010-N05). BOEMRE has nonetheless determined
that it is appropriate for inclusion in this interim final rule because
it is consistent with the intent of the recommendations in the Safety
Measures Report. Tighter cementing practices will increase the safety
of offshore oil and gas drilling operations by improving cementing
practices; they also will support the other requirements in this
interim final rule.
V. Justification for Interim Final Rulemaking
Pursuant to the Outer Continental Shelf Lands Act (OCSLA), the
Secretary has an affirmative obligation to ensure that drilling
operations undertaken on the OCS are conducted in a manner that is safe
for the human, marine, and coastal environment (43 U.S.C. 1332(6),
1334(a), 1347, and 1348; and 30 CFR 250.106). The April 20, 2010,
blowout of the BP Macondo well and the explosion on the Deepwater
Horizon killed 11 workers and resulted in the Nation's largest oil
spill ever, with substantial environmental and economic impacts.
On May 28, 2010, the Secretary ordered the suspension of certain
oil and gas drilling operations in deepwater (greater than 500 feet).
On July 12, 2010, the Secretary rescinded that order and replaced it
with a new decision ordering the suspension in the Gulf of Mexico (GOM)
and Pacific regions of the drilling of wells using subsea BOPs or
surface BOPs on a floating facility, with certain exceptions for
intervention wells, injection and disposal wells, abandonments,
completions, and workovers. This suspension order applies by its terms
until November 30, 2010, although the order notes that it could be
lifted earlier than that date.
As mentioned previously, on April 30, 2010, the President also
directed the Secretary to conduct a thorough review of the Deepwater
Horizon event and to report within 30 days on additional
[[Page 63355]]
measures needed to improve the safety of oil and gas operations on the
OCS. On May 27, 2010, the Secretary delivered the Safety Measures
Report to the President. This Safety Measures Report incorporated
recommendations from BOEMRE, as well as from a wide range of experts
from government, academia, and industry. In developing the Safety
Measures Report on which this interim final rule is based, the
Department consulted with a wide range of experts in state and Federal
government, academic institutions, and industry and advocacy
organizations. In addition, draft recommendations were peer reviewed by
seven experts identified by the NAE.
Numerous investigations are ongoing, and the precise causes of the
well blowout and explosion are not fully known; however, the fact that
a blowout occurred clearly indicates problems with the well's line of
defense, which could include BOP systems, casing and cementing
programs, and fluid displacement procedures. Accordingly, it is not
necessary to await certainty regarding the cause of the blowout before
promulgating this interim final rule.
Circumstances suggest that, while a blowout and spill of this
magnitude have not occurred before on the OCS, it is unlikely that the
problems are unique to the Deepwater Horizon and BP's Macondo well. As
noted in the July 12, 2010, decision of the Secretary to suspend
certain offshore permitting and drilling activities, most BOPs used in
drilling on the OCS are of similar design and are produced by a limited
number of manufacturers. Furthermore, the BOPs for the relief wells
drilled to intercept the Macondo well encountered unexpected
performance problems, initially failing to pass new testing procedures
developed in response to the Safety Measures Report, including failure
of the deadman and autoshear functions. These multiple failures raise
red flags as to the reliability of BOPs to adequately safeguard the
lives of workers and protect the environment from oil spills in
response to a large blowout. They also suggest the need to review
regulations pertaining to well casing and design, the other area of
likely failure in the Deepwater Horizon event.
Even without the full results of the pending investigations, the
obvious failures of well intervention and blowout containment systems
demonstrate that previous regulatory assumptions concerning their
reliability are inaccurate. The importance of these systems in
preventing catastrophic blowouts and oil spills indicate that genuine
harm could result from delay and lead BOEMRE to conclude that immediate
regulations are needed to better ensure the reliability of these
systems, and to protect the lives of workers, human health, and the
environment.
This interim final rule therefore, specifically addresses measures
that will increase the safety of these systems. It imposes requirements
to give greater certainty that casing and cement design and fluid
displacement are adequate for well bore integrity, and to enhance the
reliability of well control equipment.
The casing and cementing program and fluid displacement procedures
are the first line of defense in preventing a loss of well control that
could lead to a blowout. Casing and cement and drilling fluids are used
to ensure the fluids in a formation do not enter the wellbore during
drilling and completion operations. When a well is completed and
production begins, the casing and cement continue to prevent
uncontrolled flow of fluids into the wellbore. The integrity of the
casing and cement are critical to proper well control. While the extent
to which cementing and casing failures contributed to the Macondo
blowout is not yet fully known, preliminary information suggests that
the operator may have failed to follow best industry cementing and
casing installation practices. The current regulations contain general
cementing and casing requirements, but they do not specifically address
best cementing and casing installation practices. This rulemaking will
provide greater assurance that all operators will follow these safer
practices, reducing the risk of a loss of well control.
This interim final rule also strengthens requirements for BOPs. In
the event of a loss of well control, rig operators use the BOPs to
regain control of the well. This is done by closing the various rams on
the BOP stack, which shut off the flow of formation fluids to the
surface. Secondary well control system requirements (i.e., ROV
intervention capabilities and emergency back-up BOP control systems)
ensure that rig operators are able to activate various BOP rams in the
event the control system on the rig fails (e.g., loss of power).
Requirements in this interim final rule impose new standards to enhance
BOP reliability, thereby lessening the possibility of failures that
could lead to an uncontrolled blowout and spill with potentially
catastrophic consequences for workers and the environment.
Given the Deepwater Horizon blowout and resulting spill, and
because of the potential for grave harm to workers and the human,
marine, and coastal environment from any additional events, BOEMRE
concludes that existing regulations must be strengthened to more fully
protect offshore workers, the environment, and the public, and that
this situation justifies immediate imposition of the requirements of
this interim final rule.
This interim final rule applies to ongoing operations not covered
by the Secretary's July 12, 2010, suspension decision in addition to
those operations that were suspended by that decision. Immediate
imposition of the requirements of this rule is necessary for both
ongoing and suspended operations to ensure that all operations proceed
in a more safe and reliable fashion in protection of human health and
the environment. The July 12, 2010, suspension expires by its terms on
November 30, 2010, and it could be li
