Oil and Gas and Sulfur Operations in the Outer Continental 
Shelf--High Pressure High Temperature Updates

AGENCY: Bureau of Safety and Environmental Enforcement, Interior.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The Department of the Interior (DOI or Department), through 
the Bureau of Safety and Environmental Enforcement (BSEE), is adding 
requirements for new or unusual technology, including equipment used in 
high pressure high temperature (HPHT) environments; revising and 
reorganizing the information submission requirements for a project's 
Conceptual Plans and Deepwater Operations Plan (DWOP); and requiring 
independent third parties to review certain information prior to 
submission to BSEE. This final rule will improve operational and 
environmental safety and human health, while providing consistency and 
clarity to industry regarding the equipment and operational 
requirements as well as the submissions that are necessary so that BSEE 
can review and consider for approval proposed projects that would use 
new or unusual technology.

DATES: This final rule is effective on October 29, 2024. The 
incorporation by reference of certain material listed in this rule is 
approved by the Director of the Federal Register as of October 29, 
2024.

SUPPLEMENTARY INFORMATION: 

Executive Summary

    This final rule will improve operational safety and human health 
and environmental protections, while providing industry with clarity 
and consistency regarding the equipment, operational requirements, and 
submissions that are necessary for BSEE to review and approve 
operations using new or unusual technology. BSEE considers new or 
unusual technology to include equipment or procedures that the offshore 
oil and gas industry has not used previously or extensively under the 
anticipated operating conditions or has not used previously in a 
particular BSEE Outer Continental Shelf (OCS) Region, or that have 
operating characteristics outside the performance parameters 
established in 30 CFR part 250.
    Currently, operations and equipment used in HPHT environments are 
relatively new on the United States OCS. In general, an HPHT 
environment is present when well conditions have pressures greater than 
15,000 pounds per square inch absolute (psia) or have a temperature 
greater than 350 degrees Fahrenheit. Historically, most oilfield 
equipment has not been designed to withstand such high pressures and 
temperatures. Working in an HPHT environment therefore increases 
operational complexity because HPHT-associated operations require the 
use of equipment that exists at the limits of current technology and 
lacks a long operational history. Due to limited industry experience in 
HPHT environments, few industry standards directly address HPHT 
equipment and operations. Currently, BSEE carefully reviews HPHT 
projects on a case-by-case basis. To date, BSEE has received several 
applications for projects in HPHT environments and anticipates HPHT 
project interest to increase due to equipment technological 
advancements and industry capabilities to develop resources in these 
environments.
    For new or unusual technology projects, including HPHT projects, 
BSEE regulations currently:

--Require submission of information in a sequence that is not conducive 
to BSEE's review and consideration for approval of new or unusual 
technology projects because these projects typically require a more 
immediate BSEE review and approval than the regulations currently 
allow; and
--Lack specific equipment requirements because the technology is new 
and there are few applicable industry standards.

    To address these issues, this final rulemaking:

--Requires the submission of information in a sequence that provides 
both operators \1\ and BSEE the ability to evaluate whether a new or 
unusual technology project is economically and operationally feasible;
---------------------------------------------------------------------------

    \1\ BSEE administers the Departmental regulations at 30 CFR part 
250, which generally apply to ``a lessee, the owner or holder of 
operating rights, a designated operator or agent of the lessee(s). . 
. .'' 30 CFR 250.105 (definition of ``you''). For convenience, this 
preamble will refer to these regulated entities as ``operators'' 
unless otherwise indicated.
---------------------------------------------------------------------------

--Clarifies that equipment or procedures used for operations in an HPHT 
environment are considered new or unusual technology.
--Adds specific equipment requirements, particularly for barriers, 
through new regulations and the incorporation of applicable industry 
standards; and
--Requires Independent Third Party (I3P) review of operator 
submissions, in certain cases, or provides BSEE with the ability to 
require I3P review, to ensure project viability and safety.

    Currently, the DWOP process requires information to be submitted in 
two distinct phases: the Conceptual Plan phase and the DWOP phase. This 
final rule maintains the two phase DWOP process and adds additional 
requirements to each phase that will enable BSEE to thoroughly review 
proposed new or unusual technology projects. The final rule defines 
three types of Conceptual Plans: a Project Conceptual Plan, a New or 
Unusual Technology Conceptual Plan, and a New or Unusual Technology 
Barrier Equipment Conceptual Plan. A Project Conceptual Plan will be 
required for any project planned in water depths greater than 1000 feet 
or that will include the use of subsea tieback development technology, 
regardless of water depth. A New or Unusual Technology Conceptual Plan 
will be required for any project or system involving New or Unusual 
Technology equipment or procedures. A New or Unusual Technology Barrier 
Equipment Conceptual Plan will be required for any project or system 
involving new or unusual technology identified as a primary or 
secondary barrier to isolate a hydrocarbon pressure source from people 
and the environment. An operator must submit the applicable Conceptual 
Plan(s) based on the specifics of the proposed project.
    The information specific to HPHT projects submitted in the 
applicable Conceptual Plan(s) will be evaluated for adequacy prior to 
approval. The final rule's establishment of three new types of 
Conceptual Plans and the associated new timing requirements established 
in Sec.  250.226 (e.g., BSEE must approve your Conceptual Plan(s) 
before the Bureau will approve any associated permit) will provide both 
operators and BSEE with the ability to evaluate early in the project 
planning process, before permit approval, whether a new or unusual 
technology project is economically and operationally feasible. In the 
final rule,

[[Page 71077]]

the DWOP phase, during which the DWOP is reviewed, will take place 
after the Conceptual Plan(s) have been approved and the system design 
has been substantially completed.
    In addition, this final rule revises 30 CFR part 250, subpart B 
(``Plans and Information'') and the DWOP process to incorporate BSEE's 
Barrier Concept into the requirements, including for new or unusual 
technology projects. The Barrier Concept is a holistic approach to the 
barrier system based on BSEE's determination that abnormal conditions 
and/or failures are potential risks in a well or pipeline system. When 
an abnormal condition or failure occurs, it must be detectable, and 
upon detection, its source must be isolated behind redundant barriers. 
BSEE considers a barrier or barrier system to be any engineered 
equipment, materials, component, or assembly that is intended to 
contain a hydrocarbon pressure source(s) to prevent harm to people or 
the environment. This final rule defines the types of equipment that 
BSEE considers to be sufficient barriers and how barriers must be used. 
The final rule also includes portions of the Barrier Concept in the 
DWOP process under the New or Unusual Technology Barrier Equipment 
Conceptual Plan as a means of ensuring that new or unusual technology 
projects include sufficient barriers, which will enhance protections 
for people and the environment. This rule incorporates into the 
regulations the existing BSEE policy on the Barrier Concept discussed 
in Notice to Lessees (NTLs) 2009-G36, Using Alternate Compliance in 
Safety Systems for Subsea Production Operations; 2019-G02, Guidance for 
Information Submissions Regarding Proposed High Pressure and/or High 
Temperature (HPHT) Well Design, Completion, and Intervention 
Operations; and 2019-G03, Guidance for Information Submissions 
Regarding Site Specific and Non-Site Specific HPHT Equipment Design 
Verification Analysis and Design Validation Testing.
    Furthermore, this final rule revises the DWOP process to require 
I3P review of equipment or procedures identified in a New or Unusual 
Technology Barrier Equipment Conceptual Plan. This final rule also 
allows BSEE to require an operator to use an I3P to review certain 
equipment or procedures identified in a New or Unusual Technology 
Conceptual Plan. Independent third parties have been used as a 
longstanding industry practice to support verifications that ensure 
project viability and safety. I3P review provides an additional review 
in circumstances where proposed equipment or processes may be 
technically complex and require a high degree of specialized 
engineering knowledge, expertise, and experience to evaluate.

I. Background

A. BSEE Statutory and Regulatory Authority and Responsibilities

    The applicable authority for this rulemaking is the Outer 
Continental Shelf Lands Act (OCSLA), 43 U.S.C. 1331-1356a. OCSLA, 
enacted in 1953 and substantially revised it in 1978, authorizes the 
Secretary of the Interior (Secretary) to lease the OCS for mineral 
development and to regulate oil and gas exploration, development, and 
production operations on the OCS. The Secretary delegated authority to 
perform certain of these functions to BSEE.
    To carry out its responsibilities, BSEE regulates offshore oil and 
gas operations to enhance the safety of exploration for and development 
of oil and gas on the OCS, ensure that those operations protect the 
environment, and implement advancements in technology. BSEE also 
conducts onsite inspections to ensure compliance with regulations, 
lease terms, and approved plans and permits. Detailed information 
concerning BSEE's regulations and guidance to the offshore oil and gas 
industry may be found on BSEE's website at: https://www.bsee.gov/guidance-and-regulations.
    BSEE's regulatory program covers a wide range of OCS facilities and 
activities, including drilling, completion, workover, production, 
pipeline, and decommissioning operations. This rule is applicable to 
operations that involve deepwater development projects, subsea tieback 
development technology, or projects or systems that use new or unusual 
technology.

B. Purpose and Summary of the Rule

    The purpose of this rule is to improve the requirements and 
information submission process for oil and gas operations in deepwater 
and for operations that propose the use of new or unusual technology 
equipment or procedures. The final rule achieves this purpose by adding 
requirements for new or unusual technology projects, including HPHT 
projects, reorganizing the deepwater project information submission 
process, and requiring I3P review of certain submissions.
    Together, these regulations will better ensure that operators 
consider and submit sufficient information to BSEE at an early enough 
stage in the process so that operators and BSEE can adequately address 
any issues concerning equipment selection, design, and fabrication.

C. Summary of Documents Incorporated by Reference

    The Office of the Federal Register has regulations concerning 
incorporation by reference. 1 CFR part 51. These regulations require 
that, for a final rule, agencies must discuss in the preamble to the 
rule the way in which materials that the agency incorporates by 
reference are reasonably available to interested persons and how 
interested parties can obtain the materials. Additionally, the preamble 
to the rule must summarize the material. 1 CFR 51.5(b). The text 
immediately below summarizes the documents incorporated by reference in 
30 CFR 250.198 and the changes to the regulatory text. This section of 
the preamble concludes with a discussion regarding the availability of 
the documents that are incorporated by reference.

this equipment is extremely important. This specification identifies 
the tooling necessary to handle, test, and install the equipment. It 
also specifies the parameters for design, material, welding, quality 
control (including factory acceptance testing), marking, storing, and 
shipping for both individual sub-assemblies (used to build complete 
subsea tree assemblies) and complete subsea tree assemblies. This 
document is currently incorporated by reference elsewhere in 30 CFR

Sec. Sec.  250.518 and 250.619.
    NACE Standard MR0175-2003, Standard Material Requirements, Metals 
for Sulfide Stress Cracking and Stress Corrosion Cracking Resistance in 
Sour Oilfield Environments, Revised January 17. 2003.
    This standard describes general principles and provides 
requirements and recommendations for the selection and qualification of 
metallic materials for equipment used in oil and gas production, and in 
natural-gas sweetening plants, in hydrogen sulfide (H2S)-
containing environments, where the failure of such equipment can pose a 
risk to the health and safety of the public and personnel or to the 
environment. Application of this standard can help avoid costly 
corrosion damage to equipment. This standard supplements, but does not 
replace, the material requirements contained in applicable design 
codes, standards, or regulations. This standard also addresses all 
mechanisms of cracking that can be caused by H2S, including 
sulfide stress cracking, stress corrosion cracking, hydrogen-induced 
cracking and stepwise cracking, stress-oriented hydrogen-induced 
cracking, soft zone cracking, and galvanically induced hydrogen stress 
cracking. This standard does not include and is not intended to include 
design specifications. This document is currently incorporated by 
reference elsewhere in 30 CFR part 250, and BSEE is adding references 
of this standard in existing Sec. Sec.  250.518 and 250.619.

II. Discussion of Public Comments on the Proposed Rule

    In response to the proposed rule, BSEE received 9 sets of submitted 
comments containing general statements, specific comments on the 
proposed provisions, and discussions of provisions not included in the 
proposed rule. Comments included submittals from the following 
entities: 1 manufacturer, 5 companies, 1 industry organization, 1 non-
governmental organization, and 1 classification society. All relevant 
comments are posted at the Federal eRulemaking portal: https://www.regulations.gov. To access the comments at that website, enter 
BSEE-2021-0003 in the Search box. BSEE reviewed all comments submitted, 
and this section of the preamble contains brief summaries of the 
relevant comments, as well as BSEE's responses.
    BSEE received multiple comments expressing general support for the 
proposed rule. Some of the commenters who expressed general support for 
the proposed rule also provided specific detailed comments, which we 
have addressed further in section III of this preamble. While these 
commenters voiced support broadly for certain proposed changes, some of 
them also disagreed with other specific proposals and provided 
suggested revisions. Multiple commenters also provided statements or 
comments that were not relevant to the proposed rule, and therefore 
BSEE is not addressing them in this final rule.

General Comments

    Summary of comments related to incremental submission of plans: 
Multiple commenters suggested that BSEE clarify the regulations to 
allow for incremental submission of certain plans.
    Response: BSEE disagrees with the commenters' suggestions to allow 
for incremental submission of certain plans. Incremental submission of 
plans would complicate the BSEE approval process and require additional 
BSEE time and resources to verify compliance with all requirements. 
This piecemeal approach increases the potential for errors or gaps 
within the plans, which may delay project implementation. The DWOP 
process is purposefully divided into

[[Page 71079]]

multiple plans to allow BSEE approval of certain operations as the 
project is developed. For example, BSEE approval of certain Conceptual 
Plans would allow for the wells to be completed or the installation of 
certain equipment, while BSEE approval of the DWOP would allow for well 
production. BSEE requires all pertinent information associated with the 
applicable plans within the DWOP process to be submitted as required in 
Sec. Sec.  250.220 through 250.248. Furthermore, the final rule 
provides clarity for the appropriate timing and submission requirements 
for all plans covered under the DWOP process (e.g., see revisions to 
Sec. Sec.  250.201, 250.220, 250.225, and 250.226). This final rule 
also clarifies that not all projects will require the submittal of each 
of the three Conceptual Plans and a DWOP. Specifically, certain New or 
Unusual Technology Conceptual Plans or New or Unusual Technology 
Barrier Equipment Conceptual Plans may not be required to have an 
associated Project Conceptual Plan or DWOP.

Comments Related to the Independent Third Party (I3P)

    Summary of comments: Multiple commenters expressed concerns that 
the proposed rule would substantially expand the role of I3Ps beyond 
the scope of expected duties. The commenters also requested 
clarification regarding the role and expected deliverables of I3Ps, 
including I3P actions concerning verification, validation, and 
certification and how those fit in with the terms ``fit for purpose'' 
and ``fit for service.''
    Response: BSEE agrees with the commenters that the I3P requirements 
should be clarified and throughout this rulemaking has revised the 
roles and expected responsibilities for I3Ps. For example, BSEE has 
provided supplemental regulatory text that clarifies the meaning of the 
terms ``fit for purpose'' and ``fit for service'' and to identify that 
an I3P makes a ``fit for purpose'' determination and an operator makes 
a ``fit for service'' determination. These added definitions are 
consistent with the guidance of BSEE NTL Nos. 2019-G02 and 2019-G03.
    In response to the comments, BSEE has also removed the term 
``certification'' as it pertains to determining what is ``fit for 
purpose'' and ``fit for service'' and is clarifying that a statement 
from the appropriate entity is sufficient instead of a certification 
statement.\2\ BSEE has also removed the term ``certification'' as it 
pertains to I3Ps throughout Subpart B. See Section III of this preamble 
for a complete discussion regarding the updated I3P expectations and 
requirements.
---------------------------------------------------------------------------

    \2\ Notwithstanding this terminology change, operators and I3Ps 
should be aware that willfully and knowingly making materially false 
statements to the government are actionable under 18 U.S.C. 1001.
---------------------------------------------------------------------------

    Summary of comment: A commenter acknowledged that I3Ps can be a 
powerful tool, but stated that BSEE must ensure that the criteria for 
third party reviewers is sufficient.
    Response: BSEE agrees with the commenter that I3Ps can be a useful 
tool for added review and verifications. In this final rule, BSEE has 
clarified the I3P qualifications and expectations to help ensure 
appropriately qualified entities are performing this important work and 
that BSEE has clear oversight of the process.
    Summary of comments related to continued use of NTLs: Multiple 
commenters expressed concerns with consistency between existing BSEE 
guidance (NTL No. 2019-G02 and NTL No. 2019-G03) and the proposed rule 
and were unsure as to whether BSEE intended to replace or supplement 
the BSEE guidance.
    Response: BSEE has made many revisions throughout the final rule to 
provide consistency with existing BSEE guidance in the NTLs. For 
example, BSEE has added the definitions of ``fit for purpose'' and 
``fit for service'' to the final rule to provide that consistency (see 
Section III of this preamble for discussions on consistency and 
clarification of the content of the guidance documents). If the NTLs 
conflict with this final rule, the final rule is controlling, and BSEE 
will revise the NTLs, as necessary.
    Summary of comments related to significance determination: A 
commenter asserted that the rule was incorrectly identified as a non-
significant action. The commenter asserted that the rule includes 
several significant alterations to the DWOP process currently used by 
both the oil and natural gas industry and BSEE, including a substantial 
expansion of the circumstances that would trigger the DWOP process, as 
well as an expansion of the circumstances that would require review by 
I3Ps. The commenter requested that BSEE reevaluate the significance 
analysis.
    Response: The Office of Information and Regulatory Affairs (OIRA) 
in the Office of Management and Budget determined that this rule is not 
significant for purposes of Executive Order 12866, as amended. BSEE 
disagrees with the commenter's assertion that the rule should be 
considered significant. The DWOP process that is clarified in this rule 
is the same process that BSEE has been using to review new and unusual 
technologies and new and unusual technologies barriers for more than 20 
years. Under its current regulations, BSEE has established conditions 
of approval through the DWOP process under the authority of Sec.  
250.141, ``May I ever use alternate procedures or equipment?'', to 
enable it to review and approve applications using new technologies. In 
response to the commenters request to reevaluate the significance 
criteria, BSEE has conducted a final analysis of the regulations, and 
OIRA confirmed that this final rule is not a significant regulatory 
action. A summary of that analysis can be found in Section V of this 
preamble.
    Summary of comments related to grandfathering ongoing approvals and 
actions: Multiple commenters expressed concerns that the proposed rule 
would impact and significantly delay ongoing approval for projects that 
have already been proposed and subject to BSEE review before the 
effective date of the rule, or for equipment that has already been 
reviewed by BSEE. The commenters identified that some of the projects 
have already undergone years of review.
    Response: BSEE agrees with the commenters and revised Sec.  250.201 
by adding new paragraph (d) to clarify that all plans covered under the 
DWOP process that are initially submitted after the effective date of 
this rule must comply with the requirements of this subpart. DWOPs that 
were submitted to BSEE for approval prior to the effective date of this 
rule, including revised or amended DWOPs, do not have to follow the new 
DWOP process and may continue to follow the process that was in effect 
before the effective date of these final regulations. BSEE considers 
Conceptual Plans and DWOPs to be submitted when BSEE receives the 
initial submittal. BSEE will work on a case-by-case basis to ensure 
there are no significant delays for those ongoing projects or reviews. 
BSEE may allow review pursuant to the new regulations if such a review 
is requested by the operator.

Comments Related to the Use of New or Unusual Technology

    Summary of comments: A commenter requested that BSEE not classify 
equipment or procedures used in an HPHT environment as new or unusual 
technology, as the HPHT technology is expanding and maturing.

[[Page 71080]]

    Response: BSEE disagrees with the commenter and does not consider 
HPHT equipment to be fully mature. BSEE considers HPHT equipment to be 
potentially high risk because it requires complex material selection, 
material testing, design analysis, and validation testing. BSEE 
understands and supports many engineering standards that are being 
updated to address HPHT design. However, at this point BSEE intends for 
operations in an HPHT environment to be fully reviewed and approved to 
ensure safety and environmental protection. BSEE will continue to 
evaluate HPHT projects, and at an appropriate time may revise the 
regulations to remove HPHT from being considered new or unusual 
technology once BSEE determines that it is fully established.
    Summary of comments: Multiple commenters recommended that BSEE 
provide means to communicate about equipment or procedures that are or 
are not considered new or unusual technology and a means for equipment 
or procedures initially deemed to be new or unusual technology to later 
be deemed as falling outside the definition of ``new or unusual 
technology.''
    Response: BSEE is not developing a list of equipment or procedures 
considered to be new or unusual technology. It is impractical for BSEE 
to list every potential piece of equipment or procedure that may fall 
under the definition of new or unusual technology as there may be an 
infinite number of variations of each type of equipment or procedure. 
Furthermore, BSEE reviews each piece of equipment and procedure 
individually to ensure that the equipment or procedure is appropriate 
for the specific project proposed. This rule sets the parameters of 
what is considered new or unusual technology. BSEE anticipates that 
over time, consistently successful implementation of certain new or 
unusual technologies will lead to BSEE revising the criteria for 
determining what is considered new or unusual technology. After 
appropriate experience and analysis of data, in a future rulemaking 
BSEE may decide to no longer treat certain equipment or procedures used 
in an HPHT environment as new or unusual technology. For example, BSEE 
has become familiar with the freestanding hybrid riser (FSHR) systems 
and does not consider that equipment new or unusual technology. In 
2019, BSEE removed many of the FSHR prescriptive requirements and 
associated certifications from the DWOP (see 84 FR 21932).
    Summary of comments: Multiple commenters expressed concerns that 
only operators can propose the use of new or unusual technology under 
the DWOP process.
    Response: The current regulatory structure focuses on entities--
such as lessees, operators, and grant holders--that submit permits to 
BSEE for review and approval; this final rule, therefore, focuses on 
regulation of those entities that use the permitting processes.
    Summary of comments: Multiple commenters expressed concerns that 
the full DWOP process should not be required to facilitate review of 
new or unusual technology and recommended that BSEE provide clear 
expectations and timing for all plans covered under the DWOP process 
and actions or operations that can be taken during the process.
    Response: In this final rule, BSEE has clarified the DWOP process 
and the timing associated with each Conceptual Plan and the DWOP, as 
applicable. BSEE has revised multiple sections to reflect the 
appropriate timing (including what actions or operations can be taken 
during the DWOP process) and submission requirements for all plans 
covered under the DWOP process (e.g., see revisions to Sec. Sec.  
250.201, 250.220, 250.225, and 250.226). BSEE has also clarified in 
other sections (see, e.g., Sec.  250.220) that certain New or Unusual 
Technology Conceptual Plans or New or Unusual Technology Barrier 
Equipment Conceptual Plans (which may be used for drilling and 
decommissioning) may not be required to have an associated Project 
Conceptual Plan or DWOP. This clarification helps limit burdens on 
industry, as not every proposed use of new or unusual technology will 
require the submission of all plans defined in the DWOP process; only 
those plans that are applicable will be required. There is a difference 
between the DWOP process and submitting a DWOP. The DWOP process 
identifies the overarching requirements for all associated plans (i.e., 
the Project Conceptual Plan, New or Unusual Technology Conceptual Plan, 
New or Unusual Technology Barrier Equipment Conceptual Plan, and the 
DWOP). The DWOP itself is just one plan included within the DWOP 
process. BSEE expects operators to follow the DWOP process as 
appropriate, which may only require the submittal of a certain 
Conceptual Plan.
    Summary of comments: A commenter expressed concerns that the 
proposed rule is overly prescriptive when identifying new or unusual 
technology and barriers. This commenter expressed that the proposed 
rule may limit or stifle innovation.
    Response: BSEE disagrees with the commenter's concerns that the 
rule is overly prescriptive. These regulations outline the requirements 
and expectations for using new or unusual technology. These regulations 
will not limit or stifle innovation because BSEE uses the DWOP process 
to evaluate and approve new or unusual technology, not to limit the 
type of technology that may be submitted. BSEE has worked successfully 
with industry for many years to implement new or unusual technology, 
and BSEE will continue to work with any operator on the proposed use of 
any new or unusual technology, even if that use is not explicitly 
identified in the regulations. If an operator has any questions about 
the applicability of the regulations to any new or unusual technology 
or how the process will work for a specific equipment or process, that 
operator may contact the appropriate Regional Supervisor for guidance 
and actions on a case-by-case basis.
    Summary of comments related to overlap between the contents of 
Conceptual Plans and the DWOP: Multiple commenters expressed concerns 
that there is significant overlap among the Conceptual Plans and the 
DWOP requirements for the submission of information.
    Response: BSEE agrees in part that the Conceptual Plans and the 
DWOP may require the submission of similar information. However, the 
final rule will not significantly change the contents and requirements 
of the Project Conceptual Plan and the DWOP. This final rule clarifies 
the nature of the required information submitted with each Conceptual 
Plan and DWOP (see revisions to Sec. Sec.  250.227 through 250.242). 
BSEE recognizes that the New and Unusual Technology Conceptual Plan and 
New and Unusual Barrier Equipment Technology Conceptual Plan have 
potentially similar requirements relative to the Project Conceptual 
Plan and DWOP. However, the Conceptual Plans require the general 
operational concepts and basis of design while the DWOP identifies the 
specific design, fabrication, installation, and operational 
requirements for the equipment.
    Summary of comments: Multiple commenters requested that BSEE 
provide guidance for using alternate procedures or equipment requests 
for using industry standards not incorporated by BSEE. A commenter also 
recommended BSEE make the process for granting alternate procedures or 
equipment and departure requests transparent to the public.
    Response: Current BSEE regulations already outline the requirements 
for

[[Page 71081]]

alternate procedures or equipment and departures in accordance with 
Sec. Sec.  250.141 and 250.142, respectively. In reference to the 
transparency of the alternate procedure or equipment and departure 
requests, BSEE posts approval information on the BSEE website at: 
https://www.data.bsee.gov/Company/Approvals/Default.aspx.
    Summary of comments: A commenter requested that BSEE increase 
inspections, develop procedures to effectively enforce safety 
violations, and improve oversight measures to fulfill its mandate.
    Response: This rulemaking clarifies the DWOP process to ensure BSEE 
receives proper information to evaluate and approve new or unusual 
technology. BSEE has an established inspection program independent of 
the DWOP process to help ensure compliance with the regulations and 
enforce safety requirements. The equipment approved by BSEE through the 
DWOP process will be inspected pursuant to the existing inspection 
program. This rule does not alter the existing inspection program for 
the actual operations. That inspection program is outside of the scope 
of this rulemaking. However, BSEE is always seeking to improve its 
regulatory oversight and enforcement and appreciates receiving relevant 
recommendations.
    Summary of comments: A commenter expressed concern that the 
confidential and intellectual information submitted throughout the DWOP 
process should be safeguarded and not released to the public domain.
    Response: BSEE agrees with the commenter's concerns about the 
release of confidential business information and will withhold such 
information from public disclosure in accordance with law (see, e.g., 
the Freedom of Information Act, 5 U.S.C. 552).
    Summary of comment: A commenter requested that BSEE provide 
guidelines for how long DWOP process review is anticipated to take to 
better align schedules leading to first production.
    Response: BSEE cannot provide timelines for DWOP process review. 
The review time for the DWOP process is handled on a case-by-case 
basis, as each process is unique to a particular project. The size of 
the project and complexity of the project, equipment, and processes all 
factor into the length of time necessary for DWOP process review.

Summary of Comments Related to Economic Data

    A commenter stated that the Proposed Rule is expected to increase 
the cycle time by one to two years for new major capital projects due 
to the magnitude of detailed information that is required to be 
submitted with Conceptual Plans, both for projects of a conventional 
nature and for projects that involve the use of ``new or unusual 
technology'' (as defined in the Proposed Rule). The commenter asserted 
that this increased cycle time for a project will impact the economics 
and delay the schedule of the project.
    The commenter also stated that the scope of Supplemental DWOP is 
expanded well beyond the current requirements, and Table 2 of the 
Initial Regulatory Impact Analysis does not take this into account 
since it holds flat the number of Supplement DWOPs (312) to the 
Baseline for DWOP Revisions for Equipment Change (312). The commenter 
asserted that the change in scope could well cause the number of 
Supplement DWOPs to double over the baseline. The commenter further 
asserted that this would cause the 10-year cost reported in Table 7 for 
both industry and government to be under reported.
    Response: BSEE disagrees with the assertion that the rule will lead 
to substantial delays in capital projects. Industry is already 
submitting much of the project information for BSEE approval, so the 
burden is not anticipated to be significant. Based on the Final 
Regulatory Impact Analysis (RIA), the overall reporting burden on 
industry is expected to be an additional 67 hours per report compared 
to the baseline, which is not reasonably likely to delay or increase 
the cycle time for HPHT investment or deployment.
    BSEE also disagrees with the commenter's assertion that the rule 
will expand the scope and lead to large increases in the number of 
Supplemental DWOP Reports compared to the baseline. BSEE has clarified 
that certain Conceptual Plans must be submitted for each piece of 
equipment at an assembly level. This final rule also clarifies the 
scope of Sec.  250.247 and identifies what conditions require operators 
to submit Supplemental DWOPs consistent with the existing longstanding 
practice for submittal of a Supplemental DWOP. The DWOP process 
clarified in this rule is the same process that BSEE has been using to 
review new and unusual technologies and new and unusual technologies 
barriers for many years. Under existing regulations, BSEE has 
established conditions of approval for new technologies for more than 
20 years through the DWOP process under the authority of Sec.  250.141, 
``May I ever use alternate procedures or equipment?'' BSEE expects that 
the increased clarity regarding requirements and submission 
expectations provided by this rule may in fact decrease the number of 
Supplemental DWOPs that will need to be submitted. A supplement to a 
DWOP is required for applicable development projects when there are 
certain changes or additions that have not been approved by BSEE. The 
Supplemental DWOP will only be as complex as the equipment or systems 
not covered in the approved DWOP. BSEE uses this supplemental process 
to ensure that all applicable equipment is properly reviewed and 
approved before installation, well completion, or production.

III. Section-by-Section Summary and Responses to Comments on the 
Proposed Rule

    BSEE is finalizing revisions to the following regulations:

Subpart A--General

Definitions (Sec.  250.105)
Summary of Proposed Rule Revisions
    BSEE proposed to add definitions for ``BOP [blowout preventer] 
systems and related equipment'' and ``HPHT environment.''
    The proposed definition of ``BOP systems and related equipment'' 
included all pressure controlling and pressure containing well control 
equipment that may or will be exposed to the well's maximum anticipated 
surface pressure (MASP) during any phase of operation (i.e., drilling, 
completion, workover, intervention, or abandonment). The proposed 
definition also explained that well control equipment includes 
equipment that is installed for the purpose of pressure control and 
containment when it becomes necessary to physically enter a well bore 
during drilling, completion, workover, intervention, or abandonment 
modes of operation. The proposed definition of ``BOP systems and 
related equipment'' is consistent with how BSEE defined the term in NTL 
No. 2019-G03.
    The proposed definition of HPHT environment was moved from Sec.  
250.804(b) to this section and revised to refer to well conditions: (1) 
that require equipment assigned a pressure rating greater than 15,000 
psia or temperature rating greater than 350 degrees Fahrenheit; (2) 
where the MASP or shut in tubing pressure (SITP) is greater than 15,000 
psia at the seafloor for a well with a subsea wellhead or at the 
surface for a well with a surface wellhead; or (3) with a flowing 
temperature greater than 350 degrees Fahrenheit measured at the 
seafloor for

[[Page 71082]]

a well with a subsea wellhead or at the surface for a well with a 
surface wellhead. The proposed definition is consistent with BSEE's 
current definition of HPHT environments in existing Sec.  250.804(b) 
and is identical to the definition in NTL No. 2019-G03.
Summary of Final Rule Revisions
    BSEE is finalizing the proposed revisions to Sec.  250.105 with 
minor clarifications. BSEE is revising the proposed definition of BOP 
systems and related equipment to clarify that well control equipment 
includes equipment that is installed for the purpose of pressure 
control and ``pressure'' containment. This revision clarifies the 
original intent of the proposed definition.
    BSEE is also revising the proposed definition of HPHT environment 
to clarify that the criteria for evaluating MASP, SITP, and flowing 
temperatures are evaluated ``at'' the seafloor instead of ``on'' the 
seafloor. The temperature measuring device may be several feet above 
the actual seafloor. The device is generally located on the subsea tree 
and can be as high as 25 feet above the mudline.
    Summary of comments: A commenter expressed concerns that BSEE is 
not including in the rule all of the definitions contained in the 
existing BSEE NTL Nos. 2019-G02 and 2019-G03.
    Response: BSEE does not agree that adding all of the definitions 
from the NTLs are necessary. BSEE has determined that some of the 
definitions in the NTL are more appropriate in the context of the 
associated guidance contained in the NTLs. However, as described in 
Section III of this preamble and in response to comments, BSEE has 
revised the definitions of ``BOP systems and related equipment'' and 
``HPHT environment'' in the proposed rule for consistency with BSEE NTL 
Nos. 2019-G02 and 2019-G03. The referenced NTLs were created prior to 
significant BSEE HPHT reviews occurring. Now that BSEE has been 
reviewing HPHT projects for several years, we have identified what 
information is pertinent for regulation. BSEE will revise the existing 
NTLs, as necessary, to provide additional guidance for HPHT operations. 
The content of the existing applicable NTLs may still be relevant, but 
they may be revised to reflect the content incorporated into these 
regulations and updated processes.
    Summary of comments: A commenter expressed concerns that the 
definition of BOP systems and related equipment is too broad and may be 
interpreted to include equipment beyond what is traditionally 
considered a BOP system.
    Response: BSEE disagrees with the commenter. BSEE considers any 
piece of temporary equipment used to contain or control well bore 
fluids and pressure during drilling, completions, workover, 
intervention, or abandonment operations to be part of the BOP systems 
or related equipment. The concept of BOP system and related equipment 
has been utilized for many years in the existing BSEE regulations (see 
previous Sec.  250.732(c) and existing Sec.  250.735). The definition 
of BOP systems and related equipment provides clarity consistent with 
the use of the term as identified in the regulations and is not 
intended to significantly alter or expand the scope of the definition. 
If there are any questions about what equipment is properly defined as 
part of a BOP system or related equipment, please contact the 
appropriate BSEE Regional Supervisor.
    Summary of comments: A commenter stated that the definition of HPHT 
environment needs further clarity regarding the terms MASP and 
``flowing temperature'' to ensure it is applied appropriately.
    Response: BSEE disagrees with the commenter that the definition 
needs to be revised to further explain the terminology of the 
definition. This definition of HPHT environment is consistent with the 
definition of an HPHT environment in current regulations (see Sec.  
250.804(b)) and with BSEE's longstanding approach for considering HPHT 
environment criteria, including the use of the NTLs that further 
clarify applicable terms like MASP (e.g., BSEE NTL No. 2019-G03). This 
rule is not changing the meaning of any terms used within that 
definition, and their meanings will continue consistent with the 
current regulations and guidance. If there are any questions about what 
is considered an HPHT environment, please contact the appropriate BSEE 
Regional Supervisor.
Service Fees (Sec.  250.125)
Summary of Proposed Rule Revisions
    BSEE proposed to revise paragraph (a)(2) of Sec.  250.125 by adding 
new service fees for BSEE review of submittals associated with the DWOP 
process. Specifically, BSEE proposed adding service fees for processing 
a Project Conceptual Plan, New or Unusual Technology Conceptual Plan, 
New or Unusual Technology Barrier Conceptual Plan, revised DWOP, 
Combined Conceptual Plan/DWOP, and Supplemental DWOP. BSEE also 
proposed revising the cost recovery fee amount for DWOP approval to 
reflect current BSEE review and processing timeframes. These service 
and cost recovery fees would cover BSEE's costs for administrative and 
technical review of each identified submittal and processing.
Summary of Final Rule Revisions
    BSEE is finalizing the service fee categories as proposed with one 
minor textual revision in paragraph (a)(2) of Sec.  250.125. BSEE 
revised the fourth category to include the word ``Equipment'' to make 
it consistent with the title of that Conceptual Plan. BSEE is also 
revising all the proposed service fee amounts listed in paragraph 
(a)(2) to more accurately reflect the revised processes and the 
estimated BSEE review time for the listed services. For example, BSEE 
now expects a separate New or Unusual Technology Barrier Equipment 
Conceptual Plan for each separate piece of applicable equipment and has 
reduced the service fee amount accordingly. Each project may require a 
different number of New or Unusual Technology Barrier Equipment 
Conceptual Plans based on the equipment being used. Accordingly, the 
new fee reflects the BSEE evaluation time per plan and not per project, 
which was the basis of the fee initially analyzed in the proposed rule. 
The service fee amounts are revised as follows:

------------------------------------------------------------------------
                                           Proposed fee      Final fee
  Service--processing of the following:       amount          amount

[[Page 71083]]

 
    (vii) Supplemental DWOP.............           8,959           9,626
------------------------------------------------------------------------

    Summary of comments: A commenter recommended that BSEE add a fee 
schedule for an Original Equipment Manufacturer (OEM) to submit a 
generic equipment plan.
    Response: BSEE disagrees with the commenter regarding requiring an 
OEM to submit an equipment plan and to add a service fee for such a 
filing. The DWOP process requires submittal of the appropriate plans 
and permits (see Sec.  250.201) by those entities who are covered under 
the definition of ``you,'' which includes a lessee or designated 
operator. BSEE is not including the OEM as an entity to submit plans 
because an OEM is not the end user of the equipment. BSEE will review 
plans specific to each project and prefers not to review generic 
equipment plans in addition to the project-specific plans, as doing so 
would duplicate the review burden on BSEE.
    Summary of comments: A commenter expressed concerns that only one 
service fee should apply to each Conceptual Plan covering the whole 
project regardless of the number of pieces of equipment or components 
covered by the plan.
    Response: BSEE agrees in part with the commenter as only one 
service fee is required for each applicable Conceptual Plan (see 
Sec. Sec.  250.227(t), 250.228(a)(15), and 250.229(j)). BSEE, however, 
does not agree that all Conceptual Plans can cover multiple pieces of 
equipment. For example, BSEE now expects a separate New or Unusual 
Technology Barrier Equipment Conceptual Plan for each separate piece of 
applicable equipment and has reduced the service fee amount accordingly 
(see Sec. Sec.  250.226(b)(5) and 250.226(c)(5)). Because the nature of 
plan submittals and the number of plans may vary for each project, BSEE 
has determined that a service fee for BSEE review on a per-plan basis 
more accurately reflects the resources expended than a service fee on a 
per-project basis.
Documents Incorporated by Reference (Sec.  250.198)
Summary of Proposed Rule Revisions
    BSEE proposed to revise paragraph (e)(82) of Sec.  250.198, which 
currently incorporates ANSI/API Spec. 6A, Specification for Wellhead 
and Christmas Tree Equipment, to add new references to Sec. Sec.  
250.518 and 250.619, making this standard applicable to completion and 
workover operations. The proposed changes to this paragraph are 
administrative and reflect the substantive changes made to Sec. Sec.  
250.518 and 250.619 that incorporate by reference this standard and are 
addressed further in the section-by-section discussion for these two 
sections.
    BSEE also proposed to revise paragraph (e)(86) of Sec.  250.198 to 
update the incorporation of ANSI/API Spec. 11D1 to the third edition of 
that standard. BSEE reviewed the new edition and the differences 
between the second and third editions of ANSI/API Spec. 11D1 and 
determined that the third edition is appropriate to incorporate into 
the regulations. The ANSI/API Spec. 11D1 third edition now includes an 
improved testing procedure for design verification and validation of 
packers and bridge plugs. The most significant change from the second 
edition to the third edition was the addition of the enhanced 
validation of the testing processes.
    BSEE also proposed to revise paragraph (e)(91) of Sec.  250.198, 
which currently incorporates ANSI/API Spec. 17D, Design and Operation 
of Subsea Production Systems--Subsea Wellhead and Tree Equipment, 
Second Edition, to add new references to Sec. Sec.  250.518 and 
250.619, making this standard applicable to completion and workover 
operations. The proposed changes to this paragraph are administrative 
and reflect the substantive changes made to Sec. Sec.  250.518 and 
250.619 that incorporate by reference this standard and are addressed 
further in the section-by-section discussion for these two sections.
    BSEE also proposed to revise paragraph (i)(1) of Sec.  250.198, 
which currently incorporates NACE Standard MR0175-2003, Standard 
Material Requirements, Metals for Sulfide Stress Cracking and Stress 
Corrosion Cracking Resistance in Sour Oilfield Environments, Revised 
January 17, 2003, to add new references to Sec. Sec.  250.518 and 
250.619, making this standard applicable to completion and workover 
operations. The proposed changes to this paragraph are administrative 
and reflect the substantive changes made to Sec. Sec.  250.518 and 
250.619 that incorporate by reference this standard and are addressed 
further in the section-by-section discussion for these two sections.
Summary of Final Rule Revisions
    BSEE did not receive any comments on the incorporation by reference 
of the proposed industry standards in this section and is including the 
proposed language in the final rule without change.
    Summary of comments: Multiple commenters expressed general support 
for BSEE updating out of date standards and requested BSEE to consider 
many additional standards to be incorporated into the regulations.
    Response: BSEE supports the actions of ensuring referenced 
standards are not out of date and reflect the recent editions; however, 
BSEE cannot add new standards to this rulemaking without specifically 
identifying them for public comment. BSEE may consider all of the 
recommended standards for incorporation in future BSEE rulemaking 
actions.
    Summary of comments: A commenter expressed concerns that reliance 
on industry standards undermines safety.
    Response: BSEE follows the policies of OMB circular A-119, which 
directs agencies to use voluntary consensus standards in lieu of 
government-unique standards, except when they are inconsistent with law 
or otherwise impractical. BSEE recognizes the positive contribution of 
standards development and related activities. When properly conducted, 
standards development can increase productivity and efficiency in 
government and industry, expand opportunities for international trade, 
conserve resources, improve health and safety, and protect the 
environment. BSEE has reviewed the incorporated standards to ensure 
that they provide the necessary level of safety. BSEE also complies 
with the requirements to utilize standards according to the National 
Technology Transfer and Advancement Act (Pub. L. 104-113 (March 7, 
1996)).

General Information

Definitions (Sec.  250.200)

Summary of Proposed Rule Revisions
    BSEE proposed to revise paragraph (a) of Sec.  250.200 by adding 
the acronym HPHT. BSEE also proposed to revise paragraph (b) of Sec.  
250.200 by adding, revising, or removing the following definitions, as 
noted:

--Add a definition for Barrier categorization to identify barriers as 
one of the following two categories:

    Category 1 Barrier, which would mean any equipment, component, or 
assembly that functions as part of a primary barrier during any 
operational phase of its life cycle. The operational phases of the 
barrier equipment, component, or assembly are drilling, completion, 
workover, intervention, injection, production, or abandonment; and
    Category 2 Barrier, which would mean any equipment, component, or 
assembly that normally functions as part of a secondary barrier system 
in all operational phases of its life cycle, except when a primary 
barrier fails. The operational phases of the barrier equipment, 
component, or assembly are drilling, completion, workover, 
intervention, injection, production, or abandonment. BSEE may consider 
non-barrier structural components of a barrier system as Category 2 
barriers if failure of that structural component could reasonably 
result in a primary barrier failure.

--Add a definition for Primary Barrier system, which would mean the 
component or group of components that are designated as the principle 
means of isolating the source of hydrocarbons and/or pressure from 
people and the environment.
--Add the definition for Secondary Barrier system, which would mean the 
component or group of components that are designated as the secondary 
means of isolating the source of hydrocarbons and/or pressure from 
people and the environment.
--Revise the definition for New or unusual technology to include 
equipment or procedures used for any drilling, completion, workover, 
intervention, injection, production, pipeline, platform, 
decommissioning, or abandonment operation that meets any of the 
following criteria:

    (1) Has not been approved for use or used extensively in a BSEE OCS 
Region;
    (2) Has not been approved for use or used extensively under the 
anticipated operating conditions;
    (3) Has operating characteristics that are outside the performance 
parameters established in 30 CFR part 250;
    (4) Will operate in an HPHT environment as defined in proposed 
Sec.  250.105; or
    (5) Is part of a primary or secondary barrier system that uses 
materials, design analysis techniques, validation testing methods, or 
manufacturing processes not addressed in existing industry standards.

--Replace the definition for non-conventional production or completion 
technology with subsea tieback development technology. The definition 
of subsea tieback development technology would still include the 
current examples of floating production systems, tension leg platforms, 
spars, Floating Production Storage and Offloading Vessel (FPSO) 
systems, guyed towers, compliant towers, subsea manifolds, and subsea 
production components, and would add subsea wells, hybrid wells, and 
other subsea completion components to the list of examples.
--Remove the definitions of modification, offshore vehicle, resubmitted 
OCS plan, revised OCS plan, and supplemental OCS plan.
Summary of Final Rule Revisions
    BSEE received and considered comments on this section and is 
finalizing the proposed Sec.  250.200 with the following clarifying 
revisions:

--Adding the acronym for Independent Third Party (I3P). This addition 
helps provide clarity for this common term used in the regulations.
--Revising the definition of Category 1 Barrier to remove ``system'' 
from the term. BSEE is removing this term because it is unnecessary to 
define from a system level and is sufficient to define on an individual 
level. BSEE wants to ensure the flexibility to review the appropriately 
identified equipment even if only a single piece of equipment.
--Revising the definition of Category 2 Barrier to clarify that it 
means any equipment, component, or assembly that normally functions as 
part of a secondary barrier ``during any'' operational phase instead of 
``in all'' operational phases. This revision clarifies when a Category 
2 Barrier should be used. BSEE also is clarifying that BSEE may 
consider non-barrier structural components of a barrier system as a 
Category 2 Barrier if failure of this structural component could 
reasonably result in a ``primary'' barrier failure. This revision 
clarifies the consideration of a Category 2 Barrier to be consistent 
with its definition and applicability only when there is a Primary 
Barrier failure instead of any barrier failure.
--Adding the definition of Fit for Purpose to mean a determination made 
by an I3P at the conclusion of I3P review that the barrier equipment 
design has been verified and validated in conformance with recognized 
engineering standards and any additional project specification 
requirements; that the material selection, design verification 
analysis, design validation testing, and quality control are 
appropriate to justify the technical specifications; and that the 
technical specifications meet or exceed a project's site specific 
functional requirements. The addition of this definition provides 
clarity about the expectations and actions of an I3P and is consistent 
with the associated revisions to Sec. Sec.  250.226 and 250.230 through 
250.233.
--Adding the definition of Fit for Service to mean a determination made 
by the operator that the material selection, design verification 
analysis, design validation testing, and quality control of the barrier 
equipment is appropriate to justify the technical specifications and 
that the technical specifications meet or exceed a project's site-
specific functional requirements. This addition provides clarity about 
the expectations and actions of an operator when providing required 
determinations for a site-specific project and is consistent with the 
associated requirements of the DWOP process.
--Revising the definitions of Primary Barrier and Secondary Barrier by 
removing the terms ``system'', ``or group of components'', and ``of 
hydrocarbons and/or pressure'', resulting in the defined terms meaning 
the equipment, material, component, or assembly that is designated as 
the primary or secondary means of isolating the hydrocarbon pressure 
source from people and the environment. These revisions provide clarity 
and consistency with other applicable definitions (e.g., Category 1 
Barrier and Category 2 Barrier) and with how the terms are used in 
Sec.  250.206. Also based on comments, BSEE clarified the applicability 
of the barriers encompassing those that isolate a

[[Page 71085]]

``hydrocarbon pressure source.'' This clarification confirms the 
original intent of the definitions, further ensuring personnel safety 
and environmental protection from the potential release of 
hydrocarbons.
--Revising the definition of Subsea Tieback Development Technology by 
removing an unnecessary acronym and adding production risers and export 
risers to the list of applicable technology. These identified risers 
have always been an integral part of subsea tieback development 
technology and BSEE is adding them for clarification.

    Summary of comments: Multiple commenters expressed concerns that 
the definition of ``New or unusual technology'' is too broad and would 
unnecessarily expand the application of the DWOP process. Commenters 
also expressed concerns that the language ``used extensively'', which 
is used in the definition for ``New and unusual technology'', is vague 
and gives no criteria as to when equipment will no longer be considered 
new or unusual in the context of HPHT equipment. Some commenters 
recommended that the definition of new or unusual technology should not 
include equipment covered by industry standards.
    Response: BSEE disagrees in part with the commenters' concerns. 
BSEE recognizes that the definition in this rule expands the scope of 
what is considered new or unusual technology; however, this expansion 
helps cover the critical projects, equipment, or procedures identified 
by BSEE that must follow the DWOP process. BSEE has determined that 
this expanded scope is necessary to ensure safe operations in HPHT 
environments.
    To clarify the scope, BSEE has also revised other definitions in 
this final rule to clarify the equipment, materials, components, or 
assemblies that may be used (e.g., Category 1 and 2 Barriers, Primary 
and Secondary Barriers, and Subsea Tieback Development Technology). 
BSEE has also successfully used the longstanding definition of ``New or 
unusual technology'' in the current regulations in Sec.  250.200, which 
already uses the language ``used extensively'' as part of the 
definition. Accordingly, BSEE does not agree that the term will be too 
vague for its intended purposes.
    In this rule BSEE is not using industry standards as a criterion 
for determining new or unusual technology. Multiple standards could be 
used for one piece of equipment, and BSEE has not incorporated into the 
regulations every potential industry standard. Also, BSEE may not have 
reviewed or evaluated the standards not incorporated in the regulations 
prior to Conceptual Plan or DWOP submittal, and standards generally do 
not address site specific reviews of the equipment. New technology 
applications are individualized even when the same idea is used in 
different locations. BSEE needs to ensure the equipment or procedures 
are appropriate for the conditions in which they will be used. Once 
industry and BSEE understand the full risks and mitigations from the 
specific application and use, then BSEE may determine that the 
equipment no longer needs to be categorized as new or unusual 
technology.
    Summary of comments: Multiple commenters expressed concerns with 
the expectations of the I3P and operators for determining what is ``fit 
for purpose'' and ``fit for service,'' respectively. The commenters 
recommended that BSEE clarify the differences between determining what 
is ``fit for purpose'' and what is ``fit for service,'' consistent with 
BSEE guidance.
    Response: BSEE agrees with the commenters, and the final rule now 
includes definitions for both terms. The addition of these definitions 
provides clarity and certain expectations for the I3P or operator 
conducting the relevant determinations. The added definitions are 
consistent with the guidance of BSEE NTL Nos. 2019-G02 and 2019-G03, 
with minor corresponding edits to reflect their applicability specific 
to the DWOP process.
    Summary of comments: A commenter expressed concerns that the 
proposed rule extends the barrier envelope beyond the scope of 
isolating pressure systems from hydrocarbons.
    Response: BSEE agrees with the commenter. BSEE has revised the 
definitions of primary and secondary barriers to clarify applicability 
to hydrocarbon pressure sources. These revisions to the definitions 
clarify BSEEs original intent and limit the scope of the primary and 
secondary barriers to only hydrocarbon pressure sources.

What plans and information must I submit before I conduct any 
activities on my lease or unit? (Sec.  250.201)

Summary of Proposed Rule Revisions
    BSEE proposed to revise existing paragraph (a) of Sec.  250.201 to 
reflect the creation of the New or Unusual Technology Conceptual Plan, 
the New or Unusual Technology Barrier Conceptual Plan, and the Project 
Conceptual Plan. This section provides general information about each 
plan and identifies when BSEE approval is necessary. BSEE proposed 
paragraph (a) to clarify when each plan approval is required for 
certain activities. An operator is only required to submit the 
applicable Conceptual Plan(s). Each of these Conceptual Plans are 
standalone plans and are not contingent upon approval of each other.
    BSEE also proposed to remove existing paragraph (c), which includes 
the limiting information provisions. The limiting information 
provisions allow the Regional Director to limit the amount of 
information or analyses required to be included with the submitted 
plans or documents, covered by Subpart B of 30 CFR part 250, under 
certain conditions. The narrower scope of the information described in 
the proposed rule aligns with the Bureau's roles, authorities, and 
regulations established in 2011 when BSEE separated from the Bureau of 
Ocean Energy Management (BOEM) (see 76 FR 64432).
Summary of Final Rule Revisions
    BSEE received and considered comments on this section and is 
finalizing the proposed section with the following revisions based on 
the comments received:

--In paragraph (a), BSEE is adding ``(or relevant portions thereof)'' 
after the listed plans. This addition clarifies that certain lease 
activities can be conducted if the appropriate portions of the 
Conceptual Plans are submitted to BSEE and approved as identified in 
Sec.  250.226;
--In the table under paragraph (a)(1), BSEE is revising the information 
under the heading ``Additional information'' to designate the first 
paragraph as (a)(1)(i) and clarifying that the New or Unusual 
Technology Conceptual Plan must be approved by BSEE before it will 
approve any associated application or permit involving the use of new 
or unusual technology. BSEE is also adding new paragraphs (a)(1)(ii), 
(iii), and (iv) to clarify that the New or Unusual Technology 
Conceptual Plan may be independent of a project Conceptual Plan or 
DWOP, that BSEE will not approve the Conceptual Plan until all 
associated I3P Reports (if required) are submitted and reviewed by 
BSEE, and that the Conceptual Plan may not contain equipment identified 
as a primary or secondary barrier;
--In the table under paragraph (a)(2), and throughout the rule, BSEE is 
revising the name of the New or Unusual Technology Barrier Conceptual 
Plan to New or Unusual

[[Page 71086]]

Technology Barrier Equipment Conceptual Plan. This revision is made 
based on comments received to clarify the scope of the plan and to be 
consistent with the terminology and use of equipment covered by the 
plan. BSEE is also clarifying that the New or Unusual Technology 
Barrier Equipment Conceptual Plan requirements apply to new or unusual 
technology ``that is identified'' as barrier equipment. The final rule 
also revises paragraph (a)(2)(ii) to state that this type of plan must 
be approved ``by BSEE before it will approve any associated application 
or permit application (e.g., pipeline, platform, APD, APM) involving 
the use of new or unusual technology identified as barrier equipment as 
applicable for the permit scope.'' The final rule also adds new 
paragraph (a)(2)(iii), which states that BSEE will not approve this 
Conceptual Plan until all associated I3P Reports are submitted and 
reviewed by BSEE. These additions clarify the BSEE Conceptual Plan 
approval process and submittal requirements associated with the 
applicable Conceptual Plans. These additions are based on comments 
received and are consistent with the relevant revisions to the 
associated plans covered under Sec.  250.226 (``When and how must I 
submit each applicable Conceptual Plan?'');
--In the table under paragraph (a)(3), BSEE is clarifying that the 
Project Conceptual Plan may include certain new or unusual technology. 
BSEE is also revising the information under the heading ``Additional 
information'' to designate the proposed paragraph as (a)(3)(i), 
removing the incorrect reference to the Application for Permit to Drill 
(APD), and adding new paragraph (a)(3)(ii) to clarify that BSEE must 
approve any relevant new or unusual technology associated with 
completion operations before BSEE approves the Project Conceptual Plan. 
These additions clarify the BSEE Project Conceptual Plan approval 
process and submittal requirements associated with the Project 
Conceptual Plans. These revisions ensure proper information has been 
approved or is included with in the applicable Conceptual Plan for BSEE 
approval. These additions are based on comments received and are 
consistent with the relevant revisions to the Conceptual Plans covered 
under Sec.  250.226 (``When and how must I submit each applicable 
Conceptual Plan?''). BSEE removed the incorrect reference to the APD 
because it is not applicable to the Project Conceptual Plan and 
activities covered under that plan;
--In the table under paragraph (a)(4)(i), BSEE removed the reference to 
the new or unusual technology barrier equipment because it is redundant 
with the definition of new or unusual technology; and
--BSEE added new paragraph (d) to clarify that all DWOP process plans 
initially submitted after the effective date of this rule must comply 
with the requirements of this subpart.

    Summary of comments: A commenter expressed concerns that the terms 
used in the table are not consistent with the definitions and requested 
that BSEE provide clarification on when lease activities can commence 
under each applicable plan.
    Response: BSEE agrees with the commenter and has revised the table 
to reflect the additional information associated with the applicable 
plans. BSEE has also revised Sec.  250.226 to further reflect the 
actions that may be taken at each step of each applicable plan (see the 
applicable discussions of Sec.  250.226 in Section IV of this 
preamble). The revisions to this section and Sec.  250.226 further 
clarify the original intent of the proposed rule and the ability to 
conduct certain lease activities associated with the applicable plans.
    Summary of comments: A commenter requested that BSEE limit the 
request of additional information at the Conceptual Plan stage to the 
adequacy of the requirements included in the plan and the adequacy of 
the documentation or verification of details.
    Response: BSEE agrees in part with the commenter and expects the 
request for additional information under paragraph (b) to be limited to 
that applicable information needed to evaluate the proposed plan or 
permit. However, no revisions to this paragraph are necessary as the 
context of the current provisions are limited already to the scope of 
the associated plan or permit covered under paragraph (a).

How must I protect the rights of the Federal government? (Sec.  
250.202)

Summary of Proposed Rule Revisions
    BSEE proposed to move the content of existing Sec.  250.204 to this 
section without revision.
    BSEE did not receive any comments on this proposed section and is 
including the proposed language in the final rule without change.

Are there special requirements if my well affects an adjacent property? 
(Sec.  250.203)

Summary of Proposed Rule Revisions
    BSEE proposed to move the content of existing Sec.  250.205 to this 
section without revision.
    BSEE did not receive any comments on this proposed section and is 
including the proposed language in the final rule without change.

Requirements for High Pressure High Temperature (HPHT) Barrier 
Equipment (Sec.  250.204)

Summary of Proposed Rule Revisions
    BSEE proposed this new section to clarify what information an 
operator would be required to submit to BSEE if the operator plans to 
install HPHT barrier equipment. This section cross-references the 
applicable DWOP process requirements associated with the New or Unusual 
Technology Barrier Equipment Conceptual Plan (e.g. Sec. Sec.  250.229 
and 250.242). These additions are necessary to help ensure that the 
equipment is fit for service in the specific HPHT environment. BSEE's 
review and approval of information submitted during the DWOP process is 
intended to occur in conjunction with BSEE's review and approval of 
associated applications or permits (e.g., APD, Application for Permit 
to Modify (APM), pipeline, and production safety system).
Summary of Final Rule Revisions
    Based on comments received, BSEE is revising this section to 
reflect the sequential order of submission of the applicable plans and 
permits and clarify that if an operator plans to install HPHT barrier 
equipment, then it must submit information with its applicable Project 
Conceptual Plan, New or Unusual Technology Barrier Equipment Conceptual 
Plan, DWOP, and applicable permit(s). BSEE also clarified the last 
sentence of the section to include Sec. Sec.  250.229 and 250.242 as 
examples ``(e.g.,)'' of the applicable DWOP Process requirements.
    Summary of comments: A commenter expressed concerns that this 
section is inconsistent with other submittal requirements. The 
commenter also stated that certain uses of HPHT barrier equipment do 
not require every step in the DWOP Process.
    Response: BSEE agrees in part with the commenter and is ensuring 
that this section lists all plans that would be applicable to the use 
of HPHT barrier equipment. BSEE disagrees with the commenter that 
revisions are necessary

[[Page 71087]]

to demonstrate that only parts of the DWOP process apply. The last 
sentence of this section already states that the operator must follow 
the applicable DWOP process requirements. This does not mean that every 
DWOP process step must be followed as there are situations where 
certain parts may not be required. For example, certain New or Unusual 
Technology Barrier Equipment Conceptual Plans do not require submittal 
of a DWOP. BSEE is revising the last sentence of the paragraph to 
include a general reference to Sec. Sec.  250.229 and 250.242 as 
examples of possible DWOP process requirements.
    BSEE proposed to reserve Sec.  250.205 and this section is reserved 
in this regulation.

Barrier Equipment and Systems

What equipment does BSEE consider to be a barrier? (Sec.  250.206)

Summary of Proposed Rule Revisions
    BSEE proposed that this section codify some of the barrier concepts 
from BSEE NTL No. 2009-G36. Many parts of existing BSEE regulations 
under 30 CFR part 250, subparts D, E, F, G, H, J, and Q, are dedicated 
to establishing barrier requirements. This section would clarify that 
BSEE considers a barrier or barrier system to be any engineered 
equipment, materials, component, or assembly that is installed to 
contain a hydrocarbon pressure source(s) to prevent harm to people or 
the environment. BSEE recognizes barriers that are either non-
mechanical or mechanical in nature, permanently or temporarily 
installed, pressure controlling, and/or pressure containing barriers. 
Pressure controlling barriers must be able to be activated on demand. 
The proposed rule also clarified that barriers or barrier systems are 
required to be able to function and/or be pressure tested repeatedly to 
defined acceptance criteria. If the barrier or barrier system is 
classified as Safety and Pollution Prevention Equipment (as described 
under Sec.  250.801(a)), then it must also be compliant with the leak 
test requirements established in Subpart H of 30 CFR part 250. Any 
specific engineered equipment, materials, components, or assembly that 
exist within a barrier system that are not tested would not be 
considered a barrier. This section would not alter or impact any 
existing regulation; it only documents a principle that is the basis of 
many BSEE regulations.
Summary of Final Rule Revisions
    BSEE received multiple comments on this section and has revised the 
language in the final rule with the following revisions based on those 
comments.

--BSEE is making this section consistent with the revisions to the 
definitions under Sec.  250.200 and clarifying that barriers are 
installed to contain hydrocarbon pressure sources to prevent harm to 
people and the environment. This revision clarifies the purpose of 
barriers and provides consistent terminology;
--Removing the parenthetical that non-mechanical or mechanical in 
nature barriers are only recognized by BSEE as barriers. BSEE removed 
this parenthetical to avoid confusion and be consistent with the 
definitions and terms defined in Subpart B of 30 CFR part 250 and in 
Sec.  250.200;
--Adding an example of activating a barrier on demand to include the 
parenthetical ``(i.e., closed by an operator or automated safety 
system).'' This was added to provide guidance and clarity to the intent 
of activation of a barrier and does not change the associated 
requirement;
--Revising the second to last sentence to clarify that operators must 
function test and pressure test any pressure controlling barriers and 
adding that the operator must also pressure test any pressure 
containing barrier to defined acceptance criteria that can be repeated. 
BSEE clarified these requirements to eliminate confusion about the 
types of testing that is applicable to only pressure controlling as 
opposed to pressure containing barriers. BSEE does not specify the 
exact testing requirements or testing timeframes in order to not limit 
the use of new or unusual technology, such as single use barrier 
technology. However, the operator must identify and demonstrate the 
defined acceptance criteria to ensure that the barrier or barrier 
system can be used as designated; and
--Removing the last proposed sentence because Safety and Pollution 
Prevention Equipment is already covered under 30 CFR part 250, subpart 
H and is unnecessary in Subpart B.

    Summary of comments: A commenter recommended clarifying that the 
barriers discussed in this section apply to hydrocarbon sources to 
prevent the requirements being taken out of context for including other 
non-barrier pressure containing components.
    Response: BSEE agrees with the commenter and removed the words ``or 
other'' to clarify that the barriers are installed to contain 
hydrocarbon pressure sources. BSEE has revised this section to ensure 
consistency with the definitions of applicable terms and clarify that 
the barrier envelope covered by these definitions is limited to 
hydrocarbon pressure sources. These revisions to this section and 
corresponding edits to the definitions section clarify BSEEs original 
intent and limit the applicable scope of the barrier or barrier system 
to only hydrocarbon pressure sources.
    Summary of comments: A commenter requested BSEE to clarify the term 
``activated on demand.''
    Response: BSEE agrees with the commenter and clarified the term 
``activated on demand'' by providing a parenthetical that includes 
``closed by an operator or automated safety system.'' This 
clarification does not change the meaning or intent of the proposed 
requirements and only provides two examples of what is meant by the 
term activated on demand.
    Summary of comments: Multiple commenters expressed concerns with 
the purpose of function testing and pressure testing of barriers and 
suggested that function testing and pressure testing are only used for 
determining failures.
    Response: BSEE agrees in part with the commenters that function 
testing and pressure testing help determine failures; however, BSEE 
also uses pressure testing and function testing to help ensure that the 
barrier or barrier system is capable of being used as designed for the 
specific conditions. This section does not specify any specific 
function testing or pressure testing acceptance criteria. BSEE 
clarified these requirements to eliminate confusion about the types of 
testing that is applicable to only pressure controlling as opposed to 
pressure containing barriers. BSEE does not want to limit the use of 
new or unusual technology, such as single use barrier technology, by 
specifying the exact testing requirements or testing timeframes. 
However, the operator must identify and demonstrate the defined 
acceptance standard to ensure that the barrier or barrier system can be 
used as designated.

How must barrier systems be used? (Sec.  250.207)

Summary of Proposed Rule Revisions
    BSEE proposed to require operators to install and maintain a 
primary and secondary barrier system to prevent a loss of containment 
during any operational phase of a well, flowline, pipeline, production, 
or riser system. It is BSEE's goal to prevent loss of containment by 
minimizing single point failures wherever possible. Given the

[[Page 71088]]

probability that any barrier may fail during its service life due to 
age, corrosion, wear, damage, the environment, or accidents, the best 
mitigation is redundancy. This section would not alter or impact any 
existing regulation; it only documents a principle that is the basis of 
many BSEE regulations.
Summary of Final Rule Revisions
    BSEE did not receive any comments on this proposed section and is 
including the proposed language in the final rule without change.

Activities and Post-Approval Requirements for the EP (Exploration 
Plan), DPP (Development and Production Plan), DWOP, and DOCD 
(Development Operations Coordination Document)

How must I conduct activities under an approved EP, DPP, or DOCD? 
(Sec.  250.208)

Summary of Proposed Rule Revisions
    BSEE proposed that this section be similar to the language in 30 
CFR 550.280, How must I conduct activities under the approved EP, DPP, 
or DOCD? During the 2011 regulatory split between BSEE and BOEM, the 
content of this section was inadvertently removed from 30 CFR part 250; 
however, the content is still applicable to BSEE and should be included 
in 30 CFR part 250, as well as in 30 CFR part 550.
Summary of Final Rule Revisions
    BSEE received and considered a comment regarding this proposed 
provision and includes the proposed language in the final rule with the 
minor wording change to paragraph (a)(2) to state that the actions 
``may'' result in the lack of compensation and to fix an incorrect 
citation. BOEM removed 30 CFR 556.77 from the regulations; the new 
applicable regulation is 30 CFR 556.1102.
    Summary of comment: A commenter expressed concerns that the 
proposed language does not reflect that lease cancellation and right-
of-way forfeiture occur through a judicial process and that the last 
sentence in paragraph (a)(2) is not compatible with 30 CFR 550.185(b) 
and 30 CFR 556.77 because those provisions do not categorically 
preclude compensation in all circumstances.
    Response: BSEE disagrees with the commenter in part. The language 
in paragraph (a)(2), like 30 CFR 550.280(a)(2), accurately reflects the 
language in 43 U.S.C. 1334(c) or (d), 30 CFR 550.185, and 30 CFR 
556.1102. This addition to the BSEE regulations is not intended to 
alter any applicable judicial process or change the longstanding 
requirements of the BOEM regulations. Pursuant to the commenter's 
suggestion, BSEE has revised the regulation to reflect that the actions 
``may'' result in the lack of compensation.

What must I do to conduct activities under the approved EP, DPP, or 
DOCD? (Sec.  250.209)

Summary of Proposed Rule Revisions
    The content of this proposed section would be similar to the 
language in 30 CFR 550.281, What must I do to conduct activities under 
the approved EP, DPP, or DOCD?, paragraphs (a) and (b). During the 2011 
regulatory split between BSEE and BOEM, the content of this section was 
inadvertently removed from this part; however, the content is still 
applicable to BSEE and should be included in 30 CFR part 250, as well 
as in 30 CFR part 550.
Summary of Final Rule Revisions
    BSEE did not receive any comments on this proposed section and is 
including the proposed language in the final rule without change.

Do I have to conduct post-approval monitoring? (Sec.  250.210)

Summary of Proposed Rule Revisions
    BSEE proposed to move this section from Sec.  250.282. BSEE also 
proposed to add revisions to clarify that the Regional Supervisor may 
direct operators to conduct monitoring programs in association with 
their approved EP, DPP, DWOP, or DOCD.
Summary of Final Rule Revisions
    BSEE received and considered a comment regarding this proposed 
provision and includes the proposed language in the final rule without 
change.
    Summary of comment: A commenter stated that paragraph (b) is vague 
and ambiguous and fails to put industry on notice of the standards with 
which it must comply. The commenter recommended that BSEE revise this 
paragraph to clarify the requirements for preparing and submitting 
monitoring plans.
    Response: BSEE disagrees with the commenter and has successfully 
used the language regarding monitoring programs as a longstanding 
requirement (see previous Sec.  250.282). For example, BSEE has 
successfully directed the use of monitoring programs to minimize the 
risk of vessel strikes to protected species and provided clarifying 
guidance for implementing those monitoring programs (see BSEE NTL No. 
2012-G01).

What are my new or unusual technology failure reporting requirements? 
(Sec.  250.211)

Summary of Proposed Rule Revisions
    BSEE proposed to clarify the new or unusual technology failure 
reporting requirements. Currently, BSEE does not receive new or unusual 
technology failure data associated with approved DWOPs; however, BSEE 
has recently requested new or unusual technology failure data as a 
condition of DWOP approval. The proposed section would require an 
operator to notify BSEE within 30 days of a failure and provide a 
written report identifying the root causes of the failure. This new 
section is intended to provide BSEE with a better understanding of 
operational limitations of equipment associated with an approved DWOP.
    Existing failure and incident reporting requirements in Sec. Sec.  
250.188, What incidents must I report to BSEE and when must I report 
them?; 250.730, What are the general requirements for BOP systems and 
system components?; and 250.803, What SPPE failure reporting procedures 
must I follow?, may be used to help fulfill the new or unusual 
technology failure reporting requirements of this section. This section 
is not a substitute for other currently applicable failure or incident 
reporting requirements.
Summary of Final Rule Revisions
    Based on comments received, BSEE is revising this section by 
clarifying the definition of a failure to include any condition that 
prevents the equipment from meeting its functional specification. The 
final rule also removes the terms ``recovered and repaired or 
replaced'' as elements the proposed rule listed as triggering a 
requirement to notify the Regional Supervisor. BSEE is also revising 
the term ``written report'' to ``failure analysis report'' and 
clarifies that an operator must provide the failure analysis report as 
soon as it is available following the notification and that the failure 
analysis report must include any results and potential root causes. 
These revisions provide consistency with the same terminology and 
expectations for failure reporting used throughout BSEE regulations 
(e.g., Sec. Sec.  250.188, 250.730 and 250.803).
    Summary of comments: A commenter stated that the proposed rule is 
too broad and would capture non-failures. For example, the commenter 
stated that

[[Page 71089]]

simply needing to recover equipment does not mean the equipment 
experienced a failure and does not provide a distinction between 
failure notification and submission of a failure report.
    Response: BSEE agrees with the commenter and has revised the 
definition of failure in this section to mean any condition that 
prevents the equipment from meeting its functional specification. BSEE 
also removed the requirement for reporting if the new or unusual 
technology has to be recovered and repaired or replaced. This revision 
is necessary for consistency with similar terminology used throughout 
BSEE regulations and within the failure reporting requirements and 
submissions to BSEE. BSEE also revised this section to provide clarity 
that the failure analysis report must be submitted as soon as available 
following the notification. BSEE requires submittal of the failure 
notice first and then submittal of the failure analysis, thereby 
providing a clear order for submittal of failure information to BSEE.
    Summary of comments: A commenter expressed concerns that a root 
cause analysis may not always be possible.
    Response: BSEE agrees with the commenter and understands that there 
are circumstances where a root cause analysis may not be possible. 
Therefore, BSEE has revised this section to clarify that the report 
must include any results and potential root causes for the failure. 
BSEE values failure data and uses the failure information, including 
root causes, to identify failure trends and potential issues.
    BSEE proposed to reserve Sec. Sec.  250.212-250.219, and these 
sections are reserved in this regulation.

Deepwater Operations Plan (DWOP) Process

What is the DWOP process? (Sec.  250.220)

Summary of Proposed Rule Revisions
    BSEE proposed to move the content from Sec.  250.286 to this 
section and include the following revisions and additions:
    Proposed paragraph (a) of Sec.  250.220 would clarify that the DWOP 
process is not only used for review of subsea tieback development 
technology, but also applies to deepwater development projects and 
other projects or systems that use new or unusual technology during any 
phase of drilling, completion, workover, intervention, injection, 
production, pipeline, platform, decommissioning, or abandonment 
operations. These additions clarify when the DWOP process is necessary 
and correspond with the proposed additions of the new or unusual 
technology requirements.
    Proposed paragraph (b) would add that the DWOP process does not 
replace other BSEE applications or permits (e.g., APD, APM, pipeline, 
and platform). Other minor revisions to this paragraph reflect the 
corresponding additions to the proposed new or unusual technology 
requirements for the DWOP process.
    Proposed paragraph (c) would clarify that the DWOP process consists 
of two phases: the Conceptual Plans and the DWOP. The current DWOP 
regulations do not differentiate between the DWOP process and the DWOP 
plan itself, as they currently use the term DWOP to refer to both. This 
proposed section would clarify the terms and is intended to reduce 
confusion about the different phases of the DWOP process. The proposed 
DWOP requirements are not intended to require the submittal of a DWOP 
for operations not currently covered under the DWOP plan stage (e.g., 
drilling and decommissioning), but would require submittal of the 
appropriate Conceptual Plan. Proposed Sec. Sec.  250.227 through 
250.229 would identify the contents of the Conceptual Plans. Proposed 
Sec. Sec.  250.236 through 250.242 would identify what the DWOP must 
contain.
Summary of Final Rule Revisions
    Based on comments received, BSEE is finalizing this proposed 
section and including a new paragraph (d) to clarify that not all 
projects will require the submittal of all three Conceptual Plans and a 
DWOP. Specifically, this revision clarifies that projects requiring New 
or Unusual Technology Conceptual Plans or New or Unusual Technology 
Barrier Equipment Conceptual Plans may not be required to have an 
associated Project Conceptual Plan or DWOP.
    Summary of comments: Multiple commenters expressed concerns that 
the proposed rule lacks clarity for how the DWOP process is fully used 
for all applicable types of operations and if each step of the DWOP 
process is required for every type of equipment or operation.
    Response: BSEE agrees with the commenters and has revised this 
section by adding new paragraph (d) and the respective DWOP process 
sections to add clarity that not all projects will require the 
submittal of each Conceptual Plan and DWOP. There are circumstances 
when only a New or Unusual Technology Conceptual Plan or a New or 
Unusual Technology Barrier Equipment Conceptional Plan is required to 
be submitted to BSEE without a Project Conceptual Plan or DWOP. For 
applicability requirements, see Sec.  250.225 for each Conceptual Plan 
and Sec.  250.235 for the DWOP.

When must I use the DWOP process? (Sec.  250.221)

Summary of Proposed Rule Revisions
    BSEE proposed to move the content from Sec.  250.287 to this 
section and to clarify that the DWOP process is applicable to any 
project in water depths greater than 1000 feet and to any project that 
will include the use of subsea tieback development technology, 
regardless of water depth, or new or unusual technology for any 
drilling, completion, workover, intervention, injection, production, 
pipeline, platform, decommissioning, or abandonment operations. These 
revisions provide consistency and reflect corresponding additions to 
the proposed new or unusual technology and DWOP process requirements.
    BSEE has always required DWOPs when a development is situated in 
water depths of 1000 feet or greater or when subsea tieback development 
technology is used in any water depth. BSEE proposes to promulgate 
regulations that include our existing practices regarding the expansion 
of new or unusual technology. BSEE also proposed to add requirements 
for the DWOP process when any new or unusual technology is used for 
drilling, completion, workover, intervention, injection, production, 
pipeline, platform, decommissioning, or abandonment projects. This 
would provide consistency for all new or unusual technology reviews.
Summary of Final Rule Revisions
    BSEE received comments on this section as proposed and is 
finalizing it with a minor revision to paragraph (b) to remove the 
words ``you must.'' This paragraph was intended to be a suggestion for 
operators to contact BSEE if they have any questions about the 
classification of certain technology and is not a requirement.
    Summary of comments: Multiple commenters requested that BSEE list 
or create a database that indicates what equipment, components, or 
procedures are considered new or unusual technology or new or unusual 
barrier technology.
    Response: BSEE disagrees with this comment and is not developing a 
database to list every new or unusual technology. It is the operator's 
responsibility to ensure any new or unusual technology is appropriately 
identified and approved by BSEE before operational use. Also, such a 
database may be of limited use as each OEM may

[[Page 71090]]

have unique equipment designs and individual components do not 
necessarily all work together for specific projects.
    Summary of comments: A commenter expressed concerns that this 
section would unnecessarily expand the complete DWOP process to cover 
operations not previously covered by the process and would create 
redundant filings and impose undue burdens.
    Response: BSEE disagrees with the commenter. BSEE has clarified in 
other sections (see Sec.  250.220(d)) that projects requiring New or 
Unusual Technology Conceptual Plans or New or Unusual Technology 
Barrier Equipment Conceptual Plans (which may be used for drilling and 
decommissioning) may not be required to have an associated Project 
Conceptual Plan or DWOP. This clarification will eliminate any undue 
burden on industry by only requiring submission of the applicable plans 
in the DWOP process.
    BSEE proposed to reserve Sec. Sec.  250.222-250.224, and these 
sections are reserved in this regulation.

Conceptual Plans

What are the types of Conceptual Plans that I must submit? (Sec.  
250.225)

Summary of Proposed Rule Revisions
    BSEE proposed a new section that would identify the three types of 
proposed Conceptual Plans:

--A Project Conceptual Plan would be required for any project that is 
planned in water depths greater than 1000 feet or will include the use 
of subsea tieback development technology, regardless of water depth 
(see proposed Sec.  250.221 paragraphs (a)(1) and (2));
--A New or Unusual Technology Conceptual Plan would be required for any 
project or system that involves equipment or systems that are 
considered new or unusual technology (see proposed Sec.  250.200 for 
the definition of new or unusual technology); and
--A New or Unusual Technology Barrier Conceptual Plan would be required 
for any project or system involving new or unusual technology that is 
also identified as a primary or secondary barrier (see proposed Sec.  
250.200 for the definition of primary or secondary barriers).

    This proposed section would add clarity by describing the proposed 
types of Conceptual Plans. The proposed requirements for each 
Conceptual Plan are discussed in the applicable corresponding sections, 
Sec. Sec.  250.227 through 250.229. An operator must submit the 
applicable Conceptual Plan(s) based on specifics of the proposed 
project. The operator may be required to submit multiple Conceptual 
Plans.
Summary of Final Rule Revisions
    BSEE received comments on this section and is finalizing the 
proposed content with the following revisions based on the comments:

--Paragraph (a) is revised by adding clarification that a Project 
Conceptual Plan is also required if the project will use new or unusual 
technology for completion, injection, production, pipeline, or platform 
projects. This addition clarifies the scope of the Project Conceptual 
Plan and how applicable new or unusual technology fits within that 
plan. A Project Conceptual Plan would not be needed when new or unusual 
technology is being used for drilling or decommissioning operations.
--Paragraph (b) is revised by making the first sentence consistent with 
the definition of new or unusual technology by changing the proposed 
phrase ``involves equipment or systems'' to ``involves equipment or 
procedures''. BSEE is also adding the clarification that the New or 
Unusual Technology Conceptual Plan is applicable for drilling, 
completion, workover, intervention, injection, production, pipeline, 
platform, decommissioning, or abandonment operations. This revision 
clarifies the scope of operations covered under the New or Unusual 
Technology Conceptual Plan.
--Paragraph (c) is revised to also clarify that the New or Unusual 
Technology Barrier Equipment Conceptual Plan is applicable for 
drilling, completion, workover, intervention, injection, production, 
pipeline, platform, decommissioning, or abandonment operations. This 
revision clarifies the scope of operations covered under the New or 
Unusual Technology Barrier Equipment Conceptual Plan. BSEE also added 
``Equipment'' to the title of the plan to clarify the distinctions 
between this plan and the New or Unusual Technology Conceptual Plan.

    Summary of comments: Multiple commenters expressed concerns that 
the proposed activities of drilling and decommissioning cannot be 
covered under a Project Conceptual Plan and is outside the scope of 
previous BSEE guidance and practice. The commenters also expressed 
concerns that, if a Project Conceptual Plan is required for drilling 
operations, that requirement could not be met before drilling.
    Response: BSEE agrees with the commenters and has revised this 
section to clarify that a Project Conceptual Plan is not required for 
certain operations (e.g., drilling and decommissioning). This 
clarification is consistent with BSEE guidance and the original scope 
of the Project Conceptual Plan. BSEE does not share the commenters' 
concerns about timing requirements prior to drilling the well because 
drilling operations are not covered under the Project Conceptual Plan. 
BSEE has also further clarified in Sec.  250.226 when each applicable 
Conceptual Plan is required and the timing of conducting certain 
operations covered under each plan.
    Summary of comments: A commenter asked if a non-site-specific 
voluntary equipment Conceptual Plan and the well design Conceptual Plan 
will still be part of the HPHT approval process (see BSEE NTL No. 2019-
G02 and 2019-G03).
    Response: Non-site-specific voluntary equipment Conceptual Plans 
are not required. Operators should plan to submit site-specific 
equipment qualification for their HPHT project pursuant to Sec. Sec.  
250.228 and 250.229 as applicable. The identified content of the Well 
Design Conceptual Plans is still part of the HPHT process pursuant to 
the applicable regulations referenced in BSEE NTL 2019-G02 (e.g., see 
Sec. Sec.  250.420, 250.462, 250.505, 250.514, 250.518, 250.605, 
250.613, 250.614, and 250.732).
    Summary of comments: A commenter expressed concerns that the 
proposed rule is unclear regarding overlap between the proposed New or 
Unusual Technology Conceptual Plan and the New or Unusual Technology 
Barrier Conceptual Plan. The commenter requested that BSEE clarify that 
barrier equipment would only require the New or Unusual Technology 
Barrier Conceptual Plan and not the New or Unusual Technology 
Conceptual Plan.
    Response: BSEE agrees in part with the commenter and has revised 
the name of the New or Unusual Technology Barrier Conceptual Plan to 
the New or Unusual Technology Barrier Equipment Conceptual Plan. This 
revision clarifies the scope of the New or Unusual Technology Barrier 
Equipment Conceptual Plan and uses consistent terminology and 
descriptions of equipment covered by the plan. If a New or Unusual 
Technology Barrier Equipment Conceptual Plan is required, the operator 
would not have to also submit a New or Unusual Technology Conceptual 
Plan for the same equipment (see revisions to Sec.  250.201).

[[Page 71091]]

When and how must I submit each applicable Conceptual Plan? (Sec.  
250.226)

Summary of Proposed Rule Revisions
    BSEE proposed to move the content from Sec. Sec.  250.288 and 
250.290 to Sec.  250.226, with revisions to clarify that an operator 
must submit its Conceptual Plans to the Regional Supervisor after the 
operator decides on the general concept(s) for a project or system, and 
before it begins final engineering design of the equipment, well, well 
safety control system, or subsea production systems. These revisions 
would help ensure that the operator considers the information 
associated with the proposed Conceptual Plans when submitting an 
associated application or permit application (e.g., APD, APM, pipeline, 
platform). BSEE proposed to add a table to organize and clarify 
information associated with the three types of proposed Conceptual 
Plans as follows:
    Proposed paragraph (a) of Sec.  250.226 would include content from 
Sec.  250.290 and would further clarify that BSEE must approve a 
Project Conceptual Plan before an operator may complete a production or 
injection well or install a tree.
    Proposed paragraph (b) would add the following requirements 
regarding a New or Unusual Technology Conceptual Plan:

--The operator may not install any new or unusual technology until BSEE 
approves the New or Unusual Technology Conceptual Plan;
--BSEE must approve the New or Unusual Technology Conceptual Plan 
before BSEE will approve any associated application or permit (e.g., 
pipeline, platform, APD, APM); and
--The Regional Supervisor may require the operator to use an I3P to 
perform certain functions and verifications in accordance with Sec.  
250.231, as applicable. This addition would allow I3P services to 
assist BSEE's review of new or unusual technology that may involve 
technically complex engineering and require a high degree of 
specialized engineering knowledge, expertise, and experience to 
evaluate thereby helping to ensure that BSEE conducts appropriate 
reviews of new or unusual technology plans.

    Proposed paragraph (c) would add the following requirements 
regarding a New or Unusual Technology Barrier Conceptual Plan:

--The operator must submit a New or Unusual Technology Barrier 
Conceptual Plan for any project or system involving new or unusual 
technology that is also identified as a primary or secondary barrier;
--BSEE must approve the New or Unusual Technology Barrier Conceptual 
Plan prior to new or unusual technology barrier equipment installation;
--BSEE must approve the new or unusual technology barrier equipment 
before BSEE will approve any associated application or permit 
application (e.g., pipeline, platform, APD, APM); and
--An operator submitting a New or Unusual Technology Barrier Conceptual 
Plan must use an I3P to perform certain functions and verifications in 
accordance with proposed Sec.  250.231,

What are the I3P review requirements for Conceptual Plan reviews?

Summary of Final Rule Revisions
    Based on comments received, BSEE is finalizing the proposed content 
with the following revisions:

--Revising the introductory paragraph by removing the term ``begin 
final'' engineering design and replacing it with ``finalize.'' This 
revision clarifies the intent of the submittal timing requirement 
concerning Conceptual Plans. BSEE wants to ensure that engineering 
design is not complete before BSEE approves the concept in case any 
change is required.
--Paragraph (b)--Revising the order of content under the table heading 
``Additional information'' and adding paragraphs (b)(1)(i), (ii), and 
(iii), paragraph (b)(3), and (b)(4) to read as follows: (1) Operations 
and approval timing requirements are as follows:

    (i) You may not install any new or unusual technology until BSEE 
approves your New or Unusual Technology Conceptual Plan;
    (ii) You may not complete any production or injection well or 
install a tree before BSEE has approved all New or Unusual Technology 
Conceptual Plans associated with all well completion equipment and the 
Project Conceptual Plan; and
    (iii) BSEE must first approve your New or Unusual Technology 
Conceptual Plan associated with subsea production systems before the 
DWOP may be approved. You may install this new or unusual technology 
following BSEE permit approval (e.g., pipeline application) and prior 
to DWOP approval.
    (2) The Regional Supervisor may require the operator to use an I3P 
to perform certain functions and verifications in accordance with Sec.  
250.231, as applicable.
    (3) BSEE will not approve a New or Unusual Technology Conceptual 
Plan until you submit and BSEE reviews all I3P Reports (if any 
required).
    (4) BSEE must approve your New or Unusual Technology Conceptual 
Plan before approval of any associated application or permit (e.g., 
pipeline application, platform application, APD, APM).
    (5) You must submit separate New or Unusual Technology Conceptual 
Plans for each piece of equipment at an assembly level (e.g., BOP, 
tree, wellhead system, or tubing head spool).
    These revisions clarify certain expectations and timing for 
applicable submittals associated with the New or Unusual Technology 
Conceptual Plan.

--Paragraph (c)--Revising paragraphs (c)(2), (c)(3), and (c)(4) and 
adding paragraphs (c)(2)(i), (ii), and (iii) and paragraph (c)(5) to 
read as follows:

    (c)(2) Operations and approval timing requirements are as follows:
    (i) BSEE must approve your New or Unusual Technology Barrier 
Equipment Conceptual Plan prior to you installing new or unusual 
technology identified as barrier equipment
    (ii) You may not complete any production or injection well or 
install the tree before BSEE has approved all the New or Unusual 
Technology Barrier Equipment Conceptual Plans associated with all well 
completion equipment and the Project Conceptual Plan, and
    (iii) BSEE must first approve your New or Unusual Technology 
Barrier Equipment Conceptual Plan associated with subsea production 
systems before the DWOP may be approved. You may install this equipment 
with BSEE permit approval (e.g., pipeline application) and prior to 
DWOP approval.
    (3) BSEE must first approve your New or Unusual Technology Barrier 
Equipment Conceptual Plan before BSEE will approval any associated 
application or permit application (e.g., pipeline application, platform 
application, APD, APM).
    (4) BSEE will not approve New or Unusual Technology Barrier 
Equipment Conceptual Plans until you submit and BSEE reviews all 
required I3P Reports pursuant to Sec.  250.231.
    (5) You must submit separate New or Unusual Technology Barrier 
Equipment Conceptual Plans for each piece of equipment at an assembly 
level (e.g. BOP, tree, wellhead system, tubing head spool).
    These revisions clarify certain expectations and timing for 
applicable submittals associated with the New or Unusual Technology 
Barrier Equipment Conceptual Plan.

[[Page 71092]]

    Summary of comments: Multiple commenters expressed concerns that it 
is unrealistic to submit all the applicable Conceptual Plan information 
before beginning final engineering design.
    Response: BSEE agrees in part with the commenters and has revised 
this section to clarify the expectation that applicable Conceptual 
Plans require submittal of the plans before finalizing the engineering 
designs. This revision clarifies the intent of the submittal timing 
requirement concerning Conceptual Plans. BSEE wants to ensure that 
engineering design is not complete before BSEE approves the concept in 
case any change is required. This revision also provides latitude for 
the operators to make the determination of what constitutes a finalized 
engineering design.
    Summary of comments: Multiple commenters expressed concerns that 
the proposed rule establishes unrealistic sequencing for Conceptual 
Plan approvals and requested clarification to ensure certain operations 
(e.g., drilling) can commence as appropriate before BSEE approval of 
certain plans (e.g., Project Conceptual Plan and DWOP).
    Response: BSEE agrees in part with the commenter and has clarified 
the expectations in this section and timing requirements associated 
with each applicable Conceptual Plan. BSEE has also revised multiple 
other sections to also reflect the appropriate timing and submission 
requirements for all plans covered under the DWOP process (e.g., see 
revisions to Sec. Sec.  250.201, 250.220, and 250.225).

What must the Project Conceptual Plan contain? (Sec.  250.227)

Summary of Proposed Rule Revisions
    BSEE proposed to require a Project Conceptual Plan to include the 
basis of design that the operator would use to develop the field. 
Proposed paragraphs (a), (b), (c), and (i)(1) of Sec.  250.227 would 
reflect the content of existing Sec.  250.289. In addition, BSEE 
proposed that the section would require the operator to include certain 
information in the Project Conceptual Plan, including, but not limited 
to, information such as facility descriptions, schedule of development 
activities, certain schematics, and well information.
Summary of Final Rule Revisions
    Based on comments received, BSEE is finalizing the content of 
proposed Sec.  250.227 with the following revisions:

--Redesignating proposed paragraphs (i)(5) as (j), (j) through (q) as 
(k) through (r) respectively, and (r) as (t).
--Adding new paragraph (s) to list requests for any alternate 
procedures or equipment or departure requests associated with the 
applicable Conceptual Plans needed for well completion operations.
--Revising paragraphs (c), (d), (f), (i), (j), and (q) as follows:

    Paragraph (c)--clarifies that BSEE expects the ``estimated'' 
distance from each well.
    Paragraph (d)--changes the requirement from a confirmation that the 
subsea production safety system will comply with 30 CFR part 250, 
subpart H to a statement that the subsea production safety system will 
be designed to comply with Subpart H.
    Paragraph (f)--clarifies that for a subsea tieback to an existing 
facility the operator must submit: a description of known structural 
modifications needed to accommodate the tieback, including a statement 
about whether these may be minor or major modifications; the BSEE-
approved service life of the existing facility; and a description of 
how modifications will be evaluated for effects on the BSEE-approved 
service life.
    Paragraph (i)--clarifies (i)(1) to include a ``proposed'' well 
location plat; (i)(2) to include a ``conceptual'' subsea field 
schematic containing infrastructure as applicable and adds additional 
examples, including manifolds, subsea booster pumps, and high integrity 
pressure protection systems; and (i)(4) to include ``proposed'' 
wellbore and completion schematics.
    Paragraph (j)--clarifies that BSEE expects only a description of 
the drilling and completion systems.
    Paragraph (q)--removes the term ``activities'' because some of the 
listed items are not activities but are physical objects. BSEE also 
added risers to the list of examples applicable to new or unusual 
technology.
    BSEE understands that certain information is not finalized at this 
stage of a project, and these revisions clarify the BSEE intent to 
reflect information that is available or that can be available for the 
Project Conceptual Plan.
    Summary of comments: Multiple commenters requested that BSEE 
clarify the informational requirements for the Project Conceptual Plan. 
The commenters expressed concerns that specific information may not be 
precisely known at this stage and may be more appropriate for the DWOP.
    Response: BSEE agrees with the commenters that certain types of 
information may not be available at this stage of a project and has 
revised this section to better reflect the submission of information 
that is appropriate and available at the Project Conceptual Plan stage 
(e.g., the ``estimated'' distance from each well, a description of only 
``known'' modifications to a facility, schematics including the 
``proposed'' well locations, and a ``description'' of the drilling 
system). These revisions clarify the submission requirements and help 
alleviate the commenters' concerns regarding information availability 
for the Project Conceptual Plan.
    Summary of comments: A commenter expressed concerns that the term 
``Basis of Design'' means different things to different operators and 
recommended that BSEE remove the term.
    Response: BSEE agrees that the term ``Basis of Design'' can mean 
different things depending on the components in question and their 
application. BSEE does not agree that removing the term is necessary 
because it is a common conceptual term well understood in the industry. 
BSEE is involved with operators in the early stages of HPHT projects, 
and uncertainties regarding terminology can easily be addressed on a 
case-by-case basis to ensure submittals fulfill regulatory 
requirements.

What must the New or Unusual Technology Conceptual Plan contain? (Sec.  
250.228)

Summary of Proposed Rule Revisions
    BSEE proposed paragraph (a) of Sec.  250.228 to require certain 
information to be included in the New or Unusual Technology Conceptual 
Plan including, but not limited to, how the New or Unusual Technology 
Conceptual Plan fits within the overall site-specific project, a 
description of the technology, information on inspection and testing 
capabilities, risk assessments and failure mode analysis, operating 
procedures, and schematics.
    BSEE proposed paragraph (b) to allow for the Regional Supervisor to 
require the use of an I3P according to proposed Sec.  250.230 if the 
system or equipment requires a high degree of specialized or 
technically complex engineering knowledge, expertise, and experience to 
evaluate, or is not addressed in existing industry standards. This 
addition would help BSEE ensure that the equipment or process is 
appropriate for use in the specific environmental and operating 
conditions. In addition, the Regional Supervisor would be able to 
require operators to follow I3P requirements under Sec.  250.231, on a 
case-by-case basis. Finally, this section proposed to instruct 
operators to direct any questions about I3P requirements for New or 
Unusual

[[Page 71093]]

Technology Conceptual Plans to the Regional Supervisor.
Summary of Final Rule Revisions
    Based on comments received, BSEE is finalizing the content of 
proposed Sec.  250.228 with the following revisions:

--Paragraphs (a)(5) and (a)(5)(ii) add the requirement to describe not 
only the barrier, but also the ``safety'' system as applicable. 
Paragraph (a)(11) clarifies the detailed schematic is applicable to 
identifying all components. Paragraph (a)(13) clarifies that the list 
of alternate procedures or equipment requests and departure request 
required are those applicable to the new or unusual technology proposed 
in a New or Unusual Technology Conceptual Plan. And finally, paragraph 
(a)(14) removes the requirements for a ``certification'' and requires 
instead a statement that the technology is fit for service.
--Paragraphs (b) and (b)(1) fix incorrect cross references since the 
final rule updated the applicable section numbers, and make some 
grammatical improvements.

    Summary of comments: A commenter suggested that BSEE should move 
this section and section Sec.  250.229 outside of the DWOP process and 
expressed concerns that these sections expand the circumstances in 
which thew DWOP process is required.
    Response: BSEE disagrees with the commenter that this section 
should be moved outside of the DWOP process. However, in light of these 
concerns, BSEE has clarified the applicability of each Conceptual Plan 
to relevant operations. BSEE has clarified in other sections (e.g., see 
Sec.  250.220) that projects requiring certain New or Unusual 
Technology Conceptual Plans or New or Unusual Technology Barrier 
Equipment Conceptual Plans (which may be used for drilling and 
decommissioning) may not be required to have an associated Project 
Conceptual Plan or DWOP. This clarification helps limit the burden on 
industry as not every project using new or unusual technology requires 
every plan covered under the DWOP process.
    Summary of comments: Multiple commenters expressed concerns that 
the proposed rule inadvertently requires I3P to certify ``fit for 
service,'' a standard ostensibly outside the I3P's expertise. The 
commenters also expressed concerns with the ``certification'' statement 
associated with both ``fit for purpose'' and ``fit for service'' 
determinations and suggested that BSEE remove the term 
``certification'' from the requirements.
    Response: BSEE agrees with the commenters that there is confusion 
surrounding the terminology of ``fit for purpose'' and ``fit for 
service'' and how the I3P provides appropriate verifications and 
reviews. BSEE has therefore added definitions of both ``fit for 
purpose'' and ``fit for service'' to clarify who is responsible for 
each statement. In response to the comments, BSEE has also removed the 
term ``certification'' as it pertains to fit for purpose and fit for 
service and is clarifying that a statement from the I3P or operator 
respectively is sufficient. Such a statement is within the scope of the 
I3P's expertise.
    Summary of comments: A commenter expressed concern with the 
discretion of the Regional Supervisor to require an I3P. The commenter 
stated that this provision does not provide any regulatory certainty 
when an I3P will be required. The commenter also expressed concerns 
that the Regional Supervisor discretion for the use of an I3P may cause 
setbacks or inefficiencies to the Conceptual Plan process.
    Response: The existing HPHT regulation (e.g., Sec.  250.232) and 
NTLs provide guidelines for I3P report requirements. BSEE has 
incorporated most of the I3P guidance from the existing NTLs into these 
regulations, which provide clarity regarding when an I3P is required. 
Under Sec.  250.228(b), BSEE may require I3P reports for this type of 
Conceptual Plan when the operator proposes to use a ``system or 
equipment [that] requires a high degree of specialized or technically 
complex engineering knowledge, expertise, and experience to evaluate, 
or if existing industry standards do not address the system or 
equipment you propose to use.'' BSEE is retaining this discretion to 
allow it to adjust to equipment development and maturation over time. 
BSEE encourages operators to reach out to the Regional Supervisor early 
in the project development process to get additional clarity regarding 
when an I3P will be necessary (Sec.  250.228(b)(2)). BSEE will notify 
the operator at the earliest possible stage to help ensure there are no 
setbacks or delays with I3P applicability in the Conceptual Plan 
approval.

What must the New or Unusual Technology Barrier Equipment Conceptual 
Plan include? (Sec.  250.229)

Summary of Proposed Rule Revisions
    BSEE proposed this section to require the following information to 
be included in the New or Unusual Technology Barrier Conceptual Plan: a 
description of how the New or Unusual Technology Barrier Conceptual 
Plan fits within the overall site specific project; a diagram depicting 
the primary and secondary barriers; a list of the engineering standards 
that will be used in the equipment's material selection and 
qualification, design verification analysis, and design validation 
testing; a list of the functional requirements (i.e., environmental, 
and physical loads (magnitude and frequency)) for which the barrier 
equipment is being designed; a description of the barrier equipment's 
safety critical functions, (i.e., function(s) performed by or inherent 
to the equipment enabling it to achieve or maintain a safe state); an 
I3P nomination; an I3P verification plan; and I3P reports as required 
in proposed Sec.  250.232.
    BSEE also proposed paragraph (l) to clarify that, after BSEE 
receives all of the required I3P reports, the operator must submit a 
certification statement that the barrier equipment is fit for service 
in the applicable environment (for the specific project location).
Summary of Final Rule Revisions
    Based on comments received, BSEE is finalizing the proposed content 
with the following revisions.

--Throughout the rule--renaming the New or Unusual Technology Barrier 
Conceptual Plan as the New or Unusual Technology Barrier Equipment 
Conceptual Plan. This revision clarifies that this Conceptual Plan 
applies only to barrier equipment.
--Paragraph (b)--requiring a detailed schematic instead of a diagram.
--Paragraph (e)--clarifying that the list of alternate procedures or 
equipment requests and departure requests required are those applicable 
to the new or unusual technology barrier equipment proposed in the New 
or Unusual Technology Barrier Equipment Conceptual Plan.
--Fixing incorrect cross references due to renumbering certain sections 
in this final rule.
--Removing the I3P reports under proposed paragraph (j) and the fit for 
service statement in proposed paragraph (l), then moving that 
information to its own new section (see Sec.  250.230). As a result of 
removing the content, BSEE is also redesignating proposed paragraph (k) 
as (j).

    Summary of comments: A commenter requested clarification that HPHT 
barrier equipment intended for 20K completions (for example, HPHT 
wellheads or production liners) can be installed during the 15K 
drilling phase

[[Page 71094]]

prior to approval of the New or Unusual Technology Barrier Equipment 
Conceptual Plan.
    Response: An operator may install HPHT barrier equipment prior to 
approval of the New or Unusual Technology Barrier Equipment Conceptual 
Plan prior to the HPHT phase of operations, if all wellheads and 
casings are approved by BSEE in the applicable application or permit 
(for example see Sec.  250.410 for APDs and Sec. Sec.  250.465 and 
250.513 for APMs). However, all 20K well construction components are 
subject to equipment qualification review and BSEE approval prior to 
entering the HPHT phase of operations (see Sec.  250.229). If 
components are installed but are denied Conceptual Plan approval, the 
well will not be allowed to enter the HPHT phase of operation.

When are you required to submit an I3P Report? (Sec.  250.230)

Summary of Final Rule Revisions
    This is a new section for this final rule that contains the 
information previously covered under proposed Sec.  250.229 paragraphs 
(j) and (l). This section clarifies that submittal of the I3P reports 
is required in Sec.  250.229 and when required by BSEE pursuant to 
Sec.  250.228. BSEE added this section because I3P reports can be 
applicable to both a New or Unusual Technology Barrier Equipment 
Conceptual Plan, as well as a New or Unusual Technology Conceptual 
Plan.
Summary of Comments
    BSEE did not receive any comments on the proposed content covered 
in this new section. BSEE did receive other I3P-related comments, and 
those comments are discussed in the appropriate sections (e.g., see 
Sec. Sec.  250.228 and 250.231).

What are the requirements for the Independent Third Party (I3P) 
nomination? (Sec.  250.231)

Summary of Proposed Rule Revisions
    BSEE proposed this section to outline the requirements for the 
operator's nomination of an I3P to be used in conjunction with 
applicable Conceptual Plans. Paragraph (a) would add the nomination 
criteria for the I3P to review the design verification and design 
validation classification of the OEM, including that the I3P must be a 
technical classification society, a licensed professional engineering 
firm, or a registered professional engineer capable of providing the 
required certifications and verifications. This paragraph would also 
clarify that the I3P nomination must be submitted to BSEE for approval 
and must include the following information:

--Previous experience in third-party verification or experience in the 
design, fabrication, or installation of applicable offshore oil and gas 
equipment;
--Technical capabilities of the individual or the primary staff for the 
specific project;
--Size and type of organization or corporation;
--In-house availability of, or access to, appropriate technology to 
review the specific project (this should include computer programs, 
hardware, and testing materials and equipment as applicable);
--Ability to perform the I3P functions for the specific project 
considering current commitments (e.g., project timelines, schedules, 
and personnel availability); and
--Previous experience with BSEE requirements and procedures.

    This proposed section would help ensure that BSEE is informed of 
the I3P competencies and show that the I3P is qualified to perform the 
required verifications and certifications of Subpart B.
    Paragraph (b) would require that operators allow the I3P to access 
all associated documentation and equipment related to items in proposed 
Sec.  250.229(i) to perform the complete reviews in accordance with 
proposed Sec.  250.231. This may include OEM documents or access to the 
fabrication and manufacturing locations. The operator is responsible 
for ensuring that the I3P has the appropriate information to complete 
the required verifications and certifications. This documentation is 
necessary for the I3P to conduct its review and verify, as appropriate, 
that the equipment is designed and manufactured to operate within its 
specified operating limits.
    Multiple I3Ps may be used to conduct the applicable verifications. 
These proposed revisions are not intended to limit the number of I3Ps, 
as operators may need multiple I3Ps to cover multiple types of 
equipment covered under all applicable Conceptual Plans.
Summary of Final Rule Revisions
    Due to the addition of new Sec.  250.230, BSEE is renumbering this 
section as Sec.  250.231. Based on comments received and after review 
of comments, BSEE is also revising this section as follows:

--Paragraph (a) is removing the term ``when required by BSEE'' because 
it is redundant of the requirements for I3P nominations under the 
applicable Conceptual Plans. BSEE is also removing the reference to I3P 
``certifications'' and clarifies that the I3P provides verifications 
and validations in line with the expectations of the I3P. BSEE is 
clarifying that the operator must submit the I3P nomination(s) within 
the applicable Conceptual Plan for separate BSEE acceptance before BSEE 
will approve the applicable Conceptual Plan. This clarification was 
added because I3P nominations can be applicable to both the New or 
Unusual Technology Barrier Equipment Conceptual Plan as well as the New 
or Unusual Technology Conceptual Plan. Lastly, BSEE is also clarifying 
the list of appropriate technology in paragraph (a)(4) by removing 
``testing materials'' and that the appropriate technology is not 
limited to what is listed.
--Paragraph (b) is fixing certain cross references and clarifying that 
you must ensure the I3P has access to relevant OEM documentation, 
including relevant documentation and data labeled as confidential and 
proprietary. BSEE also wants to ensure the I3P has access to the OEM 
fabrication and manufacturing locations only if necessary to review the 
data. These revisions will help ensure the I3P has access to data 
necessary to provide the required verifications and validations.
--Paragraph (c) is added to clarify that an operator may propose to use 
an I3P previously accepted by BSEE for the same project, and not submit 
the items required under paragraph (a), if the BSEE-accepted I3P 
qualifications are still valid and applicable. The operator must also 
provide evidence of the previous I3P nomination acceptance. These 
additions help streamline the use of I3Ps within a project and reduce 
unnecessary submittal of duplicative information.

    Summary of comments: A commenter expressed concerns with the term 
``when required by BSEE'' and requested it to be removed. The commenter 
stated this change is necessary because the I3P requirements are 
sufficiently covered within the applicable Conceptual Plan 
requirements.
    Response: BSEE agrees with the commenter and has removed the term 
``when required by BSEE'' from the introductory paragraph to Sec.  
250.231. It is not necessary to include this term, as the I3P 
nomination requirement is sufficiently covered under the applicable 
Conceptual Plans.
    Summary of comments: Multiple commenters requested clarification on

[[Page 71095]]

the BSEE expectations and actions for the I3P nominations.
    Response: BSEE agrees with the commenters and has revised Sec.  
250.231(a) to clarify that operators must submit the I3P nominations 
before BSEE will approve the applicable Conceptual Plan.
    Summary of comments: Multiple commenters expressed concerns with 
allowing I3Ps unrestricted access to OEM fabrication and manufacturing 
locations.
    Response: BSEE agrees in part with the commenters' concerns over 
I3P access to OEM locations and has revised this section to reflect 
that the I3P needs access to review equipment and data, particularly 
with respect to the elements described in Sec.  250.229(i) concerning 
the I3P verification plan. BSEE wants to ensure that the appropriate 
equipment and data are available to the I3Ps to conduct the required 
verifications and validations of the project.
    Summary of comments: A commenter expressed concerns with the in-
house availability of testing materials. The commenter was concerned 
that the I3P can require re-verification and re-testing as part of the 
validation at their own facilities.
    Response: BSEE agrees in part with the commenter's concerns and 
would not expect an I3P to require re-verification or re-testing at its 
own facility. BSEE has removed the reference to testing materials from 
the list of availability of appropriate I3P technology. BSEE is 
removing this reference to help limit any misconceptions regarding the 
I3P reviews. It is BSEE's expectation that I3Ps will have the 
appropriate technology to be able to conduct the required verifications 
and validations of the specific project.
    Summary of comments: Multiple commenters expressed concerns with 
the term ``certification'' associated with I3P capabilities and 
suggested BSEE to remove the term ``certification'' from the 
requirements.
    Response: BSEE agrees with the commenters that there is confusion 
surrounding the terminology of certification for I3Ps. BSEE has added 
definitions of ``fit for purpose'' to clarify I3P requirements and 
expectations. In response to the comments, BSEE has also removed the 
term ``certification'' as it pertains to I3P qualifications.
    Summary of comments: A commenter expressed concerns that the I3P 
nomination process is too onerous and that BSEE should streamline the 
requirements to be more consistent with BSEE guidance.
    Response: BSEE agrees in part with the commenter and is adding 
Sec.  250.231(c) to clarify that the operators may propose to use a 
previously accepted I3P from the same project if the qualifications are 
still valid. This revision will help streamline the use of existing 
I3Ps within a project and help limit unnecessary duplicative 
submissions of the nomination information. This is consistent with 
current practice (previous Sec.  250.732(b)) and BSEE guidance.
    Summary of comments: A commenter expressed concerns that this 
section implies that multiple I3Ps can be nominated and that equipment, 
assembly, or systems should be verified and validated by the same I3P.
    Response: BSEE disagrees with the commenter's concerns regarding 
use of multiple I3Ps for different verifications and validations. Only 
one I3P is required for nomination per applicable Conceptual Plan at a 
time for the requirements under this section (see, e.g., Sec.  
250.229(h)). This section defines the qualifications for acceptable 
I3Ps. However, the operator retains the ability to propose different 
I3Ps for different equipment or new technologies within the same 
project. For example, a classification society may be a better I3P for 
a floating production facility, and a professional engineering firm 
maybe a better I3P for a riser design.

What are the I3P review requirements for Conceptual Plan reviews? 
(Sec.  250.232)

Summary of Proposed Rule Revisions
    BSEE proposed to identify the requirements for the I3P review. 
Paragraph (a) would require the I3P to review the following information 
regarding the applicable equipment or system:

--Basis of design, technical specification (if known at this point in 
the design process), and functional requirements (i.e., environmental 
and physical loads (magnitude and frequency));
--Risk assessment and failure mode analysis;
--Material specification, selection, qualification, and testing;
--Design verification analysis, including a structural/strength 
analysis and fatigue assessment and/or analysis;
--If fatigue is identified as a potential failure mode in the required 
fatigue assessment and/or analysis, the plan to record and gather data 
(i.e., load monitoring) in order to conduct a future fatigue analysis;
--Design validation testing; and
--Fabrication, quality management system, and inspection and test 
plan(s) that identifies the quality control/quality assurance process, 
and inspection of the final products.

    Paragraph (b) would require the I3P to submit a report to BSEE 
documenting the review of each item covered under paragraph (a) of this 
section. This paragraph would also require each report to identify all 
OEM and operator documents used during the I3P reviews.
    Paragraph (c) would require the I3P to submit a final report to 
BSEE that summarizes each of the review requirements covered under 
paragraph (a) of this section. This paragraph would also require the 
final report to include the equipment and/or system's technical 
specifications, including a certification statement that the equipment 
and/or system is fit for purpose for the technical specification by the 
I3P, and verification that the equipment's technical specifications 
meet or exceed the project's functional requirements, including a 
certification statement by the I3P that the equipment and/or system is 
fit for purpose for the proposed project.
    Paragraph (d) would clarify that, for any subsequent I3P review of 
equipment and/or system's technical specification that was previously 
approved in the operator's New or Unusual Technology Barrier Conceptual 
Plan, the Regional Supervisor may accept a final report in accordance 
with Sec.  250.231(c), including the existing certification covered 
under paragraph (c)(1) of this section, in lieu of reports required in 
paragraph (b). The I3P would be required to submit an updated 
certification statement in accordance with Sec.  250.231(c)(2) for the 
specific project.
    This section would require I3P review of all New or Unusual 
Technology Category 1 or Category 2 barrier equipment to help minimize 
the risk of loss of containment on new barrier equipment through 
reliance on the principle of qualified redundant barrier systems. The 
concept of using an I3P review process has been used in the regulations 
for various operations (e.g., Sec. Sec.  250.420, 250.732, and 250.914 
through 250.918). The I3P review process within Sec.  250.231 would be 
the same process described in NTL 2019-G03, ``Guidance for Information 
Submissions Regarding Site Specific and Non-Site Specific HPHT 
Equipment Design Verification Analysis and Design Validation Testing.'' 
The industry is currently using this NTL for the design verification 
and validation analysis for HPHT barrier equipment that will be used in 
the Gulf of Mexico. The verification processes in this section would be 
similar to the basic

[[Page 71096]]

engineering design and manufacturing methodologies found in many 
existing engineering standards.
Summary of Final Rule Revisions
    Due to the addition of new Sec.  250.230, BSEE is renumbering this 
section as Sec.  250.232. Based on comments received and after review 
of comments, BSEE is also revising this section as follows:

--The introductory paragraph clarifies the applicability of I3P for the 
applicable Conceptual Plan. This revision is necessary to clarify that 
different Conceptual Plans may have I3P requirements (e.g., the New or 
Unusual Technology Conceptual Plan or the New or Unusual Technology 
Barrier Equipment Conceptual Plan);
--Paragraph (a)(1) clarifies the technical specifications are 
applicable to the equipment and the functional requirements are 
appliable to the specific project and changed the ``i.e.'' to an 
``e.g.'' because the parenthetical provides examples;
--The contents under proposed paragraphs (c)(1) and (c)(2) are now 
located under paragraph (b), and the term ``certification'' was removed 
to clarify the I3P is required to provide statements regarding ``fit 
for purpose'' determinations; and
--The contents under proposed paragraph (d) are now redesignated as 
paragraph (c) and modified to clarify that for any new project, the 
operator may use previous I3P reviews of equipment or a system's 
technical specifications that was approved in a previous Conceptual 
Plan. This section would also clarify the intent of the proposed rule 
by adding paragraphs (d)(1), (d)(2), and (d)(3) to require the operator 
to submit certain information to the Regional Supervisor to demonstrate 
the previous I3P review is still valid (i.e., a statement that the 
previous summaries of paragraph (a) and the previous fit for purpose 
statement are still valid, verification that the equipment technical 
specifications meet or exceed the project's functional requirements, 
and a statement by the I3P that the equipment or system is fit for 
purpose for the proposed project).

    Summary of comments: A commenter suggested that BSEE should 
explicitly state that equipment that has been previously verified and 
validated through appropriate industry standards and reviewed by an I3P 
should be exempted from further I3P review, unless there are 
substantive design changes, such as a major change to the technical 
specification.
    Response: BSEE agrees in part with the commenter and has revised 
paragraph (d) to clarify the requirements for an operator to use 
previously approved I3P reviews for any new project. BSEE also 
clarified the information necessary to demonstrate that the previous 
I3P reviews are still valid for the project. These revisions would help 
streamline the use of previously approved I3Ps and limit unnecessary 
and duplicative submittals for I3P reviews and ensure that the proper 
information is submitted to demonstrate that previously approved I3P 
reviews are still valid.
    Summary of comments: Multiple commenters expressed concerns with 
the ``certification'' statement associated with both fit for purpose 
and fit for service and suggested BSEE remove the term 
``certification'' from the requirements.
    Response: BSEE agrees with the commenters that there is confusion 
surrounding the terminology of certification for fit for purpose. In 
response to the comments, BSEE has removed the term ``certification'' 
as it pertains to ``fit for purpose'' determinations and is clarifying 
that a statement from the I3P is sufficient instead of a certification. 
This revision is consistent with the addition of the definition of 
``fit for purpose'' and clarifies the role of the I3P for certain 
reviews.
    Summary of comments: A commenter expressed concerns with the 
requirements to provide a fatigue assessment or analysis and that the 
requirements are ambiguous and unclear. The commentor believes that 
such ambiguity could lead to inefficiencies and additional work that 
will further delay field and lease development.
    Response: BSEE views fatigue assessment or analysis as an important 
tool for HPHT qualification. Operators should engage early with 
equipment manufacturers to ensure the proper analysis is being 
performed. Fatigue assessment is not a new concept and is well 
understood by the industry. BSEE is not defining these terms because of 
the broad range of potential equipment or facilities covered under the 
project. BSEE has successfully used similar concepts for fatigue 
evaluation in existing regulations (see Sec.  250.908) and does not 
expect the identified terms to delay field or lease development based 
on previous Conceptual Plan and DWOP experience.

General requirements for any I3P report. (Sec.  250.233)

Summary of Proposed Rule Revisions
    BSEE proposed to clarify expectations for the I3P reports. The 
proposed rule proposed to require that an I3P report must be a 
standalone document that clearly summarizes the verification work 
performed and must contain a sufficient level of detail (i.e., 
quantitative information) and clarity to establish the basis of the 
I3P's findings and recommendation(s). Each report would be required to 
identify the OEM or operator documents reviewed, the detailed I3P 
review, and convey the results of the I3P's review without requiring 
BSEE to review any other referenced document. This section would 
establish basic expectations for I3P reports and provide consistency 
and uniformity for operator submittals and BSEE reviews. These reports 
are an important tool for BSEE to conduct appropriate reviews and it is 
imperative to ensure that these reports are comprehensive and clear. 
These reports also contain information necessary for audit purposes.
Summary of Final Rule Revisions
    Due to the addition of new Sec.  250.230, BSEE is renumbering this 
section as Sec.  250.233 and fixing any applicable cross references. 
Based on comments received and after review of comments, BSEE is also 
revising this section to clarify that the I3P reports must clearly 
summarize the required verification and validation work of the I3P. 
BSEE is also removing the proposed requirement that the I3P reports 
need to include the I3P recommendations. These revisions clarify the 
role of the I3P and provide consistency with the expectations of the 
I3P actions throughout this rulemaking.
    Summary of comments: Multiple commenters expressed concerns that 
the requirement to include I3P recommendations in the reports are 
beyond the scope of the I3P duties for reviewing for conformance with 
the specified requirements.
    Response: BSEE agrees with the commenters and has removed the term 
``recommendations'' from the regulatory requirements for I3P reports. 
BSEE wants to be consistent with the expectations and required actions 
for I3Ps when conducting required verifications and validations.
    BSEE proposed to reserve Sec.  250.234, and this section is 
reserved in this regulation.

[[Page 71097]]

DWOP Approval

When and how must I submit the DWOP? (Sec.  250.235)

Summary of Proposed Rule Revisions
    BSEE proposed to move the content from Sec.  250.291 and revise the 
section to clarify that a DWOP must be submitted to the Regional 
Supervisor after BSEE has approved the operator's project Conceptual 
Plan and the operator has substantially completed system design and 
before the operator conducts post-completion installation activities 
for a deepwater development project or for any project that will 
involve the use of subsea tieback development technology in any water 
depth, which may include new or unusual technology or new or unusual 
technology barrier equipment. This section would also clarify that 
operators cannot begin production from the well until BSEE approves the 
DWOP. The revisions to this section would help ensure that there is 
enough time for BSEE to review a DWOP, including resolution of any 
potential issues, prior to DWOP approval. The operator should consider 
the DWOP requirements when beginning to procure or fabricate the safety 
and operational systems (other than a tree, because operators may 
install a tree after Conceptual Plan approval), production platforms, 
pipelines, or other parts of the production system.
Summary of Final Rule Revisions
    BSEE is reorganizing this section to provide clarification for the 
DWOP requirements. Based on comments received and after review of 
comments, BSEE is revising this section as follows:
    Under newly designated paragraph (a), BSEE is clarifying that the 
operator must submit the DWOP before conducting installation activities 
post-well completion. BSEE is also adding paragraph (a)(3) to clarify 
that an operator must submit the DWOP for an HPHT development project, 
any project using Category 1 or 2 new or unusual technology barrier 
equipment, or any project that uses new or unusual technology that may 
impact the safety critical function of Category 1 or 2 barrier 
equipment regardless of water depth. These revisions clarify what 
projects are applicable to the DWOP submission and are consistent with 
BSEE experience and approvals of DWOPs.
    BSEE is also clarifying under newly designated paragraph (b) that 
the operator may install subsea systems and associated pipelines once 
they have applicable BSEE permit and Conceptual Plan approval. This 
clarification helps establish the order of operations and actions that 
can be taken before DWOP approval.
    Summary of comments: A commenter expressed concerns that this 
section is unclear about the use of the DWOP and the New or Unusual 
Technology Conceptual Plan or the New or Unusual Barrier Equipment 
Conceptual Plan and requested BSEE to clarify the DWOP requirements.
    Response: BSEE agrees in part with the commenter and has revised 
this section to clarify that the DWOP submission is applicable to HPHT 
development projects, as well as any project that uses Category 1 or 2 
new or unusual technology barrier equipment, or any project that uses 
new or unusual technology that may impact the safety critical function 
of Category 1 or 2 barrier equipment regardless of water depth. This 
clarification helps identify how the DWOP is applicable to certain 
project that use HPHT equipment and new or unusual technology barrier 
equipment. This revision also provides clarity and consistency with the 
definitions of certain barrier equipment and associated Conceptual Plan 
requirements.
    Summary of comments: Multiple commenters expressed concerns with 
lack of clarity regarding which actions or operations can commence at 
various stages of DWOP approval.
    Response: BSEE agrees with the commenters and has revised paragraph 
(a) of this section to clarify that the operator must submit the DWOP 
before conducting installation activities after well completion. BSEE 
is also revising paragraph (b) of this section to clarify that the 
operator may install subsea systems and associated pipelines once the 
operator has the approval of the applicable BSEE permit(s) and 
Conceptual Plan(s). However, the operator may not begin production from 
the well until BSEE approves the DWOP. These revisions provide clarity 
and consistency with current BSEE practices and expectations of the 
DWOP approval process.

What information must I submit with the DWOP? (Sec.  250.236)

Summary of Proposed Rule Revisions
    This proposed section is organizational in nature and would 
identify the types of information that the operator must submit with 
the DWOP by adding a table that lists the applicable sections and the 
information to be included. In this section, BSEE would reorganize and 
breakout the DWOP requirements by topic, as reflected in paragraphs (a) 
through (f). These revisions would improve clarity for applicable 
information requirements.
Summary of Final Rule Revisions
    BSEE did not receive any comments on these provisions of the 
proposed rule and includes the proposed language in the final rule 
without change.

What general information must my DWOP include? (Sec.  250.237)

Summary of Proposed Rule Revisions
    BSEE proposed to identify the general information that an operator 
would be required to submit in the DWOP. The content of paragraphs (a) 
and (b) of this proposed section would be moved from current Sec.  
250.292(o) and (q). This section would add paragraph (c) to require the 
submission of a list of any associated industry standards not 
incorporated in the regulations that the operator will use for project 
design or operation.
Summary of Final Rule Revisions
    Based on comments received and after review of comments, BSEE is 
revising paragraph (a) by clarifying that the DWOP must include a list 
of requests for any alternate procedures or equipment or departure 
requests in accordance with Sec. Sec.  250.141 and 250.142, 
respectively, and a list of any identified alternate procedures or 
equipment or departures that the operator may request. BSEE is also 
clarifying that if a Conceptual Plan was previously approved for the 
project that already included the alternate procedures or equipment or 
departure requests in accordance with Sec. Sec.  250.141 and 250.142 
for the specific equipment identified in a Conceptual Plan, those do 
not need to be listed in the DWOP unless the same alternate procedure 
or equipment request or departure request is needed for a different 
piece of equipment for post completion activities. These revisions 
provide clarification of the context and expectations for including 
requests covered under Sec. Sec.  250.141 and 250.142 in the DWOP.
    Summary of comments: Multiple commenters expressed concerns with 
submittal of duplicative information regarding the applicable alternate 
procedures or equipment and departure requests already identified in 
approved associated Conceptual Plans.
    Response: BSEE agrees with the commenters and has revised this 
section to clarify the required submittal of alternate procedures or 
equipment and departure requests. BSEE has also clarified that those 
requests approved in the associated Conceptual Plans do not

[[Page 71098]]

need to be submitted in the DWOP unless the same alternate procedure or 
equipment or departure requests are needed for a different piece of 
equipment for post-completion activities. BSEE does not expect 
operators to submit information of which they are unaware. However, if 
an operator is aware that it is reasonably likely to submit such 
information or departure request in the future, it is beneficial to 
include it in the DWOP at this stage to help streamline DWOP approval.

What well or completions information must my DWOP include? (Sec.  
250.238)

Summary of Proposed Rule Revisions
    BSEE proposed to move the content from current Sec.  250.292 and 
include a revision to paragraph (c) to clarify that this section 
requires information in the operator's DWOP about the design and 
fabrication of each wellbore riser system deployed from a floating 
production facility or TLP. This revision would clarify that these 
informational requirements apply to wellbore risers as components of 
the well and resolve confusion regarding the general term ``riser'' and 
its applicability of multiple types of risers (e.g., pipeline risers 
and wellbore risers) used on the OCS.
Summary of Final Rule Revisions
    BSEE did receive a comment on these provisions of the proposed rule 
but is including the proposed language in the final rule without 
change.
    Summary of comments: A commenter expressed concerns that the 
information requested in paragraphs (a) and (b) are duplicative and 
unclear.
    Response: BSEE disagrees with the commenter. These are longstanding 
requirements and have been successfully used in each applicable DWOP. 
Paragraph (a) is typically a summary narrative with a graphical 
representation of the wellbore that identifies casing and completion 
components, among other characteristics. Paragraph (b) provides further 
detail on the systems used for drilling and completion that result in 
the final schematic configuration. These requirements are not 
duplicative and have been used in existing regulations to allow for 
variations in well proposals and information requests. The information 
identified in these paragraphs is essential to ensure consistency with 
the activities to be addressed in the associated well permits.

What structural information must my DWOP include? (Sec.  250.239)

Summary of Proposed Rule Revisions
    BSEE proposed to move the content from current Sec.  250.292 to 
this section and would include a revision to paragraph (b) to clarify 
that the design, fabrication, installation, and monitoring information 
would be required for the tendon or mooring systems, including the 
turret or buoy system, as applicable. This revision would reflect 
current equipment and operations common to DWOP approvals.
Summary of Final Rule Revisions
    BSEE did not receive any comments on the content of the proposed 
provisions; however, BSEE moved the phrase ``including any major 
modifications,'' to the end of the introductory paragraph to clarify 
the intent of the paragraph.

What Production Safety System information must my DWOP include? (Sec.  
250.240)

Summary of Proposed Rule Revisions
    BSEE proposed in this section to identify the production safety 
system information that an operator would be required to submit in the 
DWOP, as applicable, to align with the activities the operator plans to 
address in the associated production safety systems application. The 
content of paragraphs (a), (b), (c), (d), and (e)(3) of this proposed 
section would be moved from current Sec.  250.292. The additions to 
this proposed section would require submission of the following 
information:

--In paragraph (e)(1)--Methods, frequency, and acceptance criteria for 
testing the underwater safety valves (USVs), surface controlled 
subsurface safety valves (SCSSVs), and boarding shutdown valves;
--In paragraph (e)(2)--The function and testing of the host facility 
emergency shutdown device (ESD) system and its interface to the subsea 
system; and
--In paragraph (f)--Information on the design, operation, maintenance, 
personnel competency, and testing of the subsea leak detection system 
to protect the subsea field/infrastructure (e.g., trees, manifolds, 
jumpers). BSEE proposed that operators must include procedures for how 
to operate the system, ensure system functionality, identify a leak, 
and take action when a leak is identified.
Summary of Final Rule Revisions
    Based on comments received and after review of comments, BSEE is 
removing the statement ``including a table summarizing the curtailment 
of production and offloading based on operational considerations'' from 
paragraph (a) and moving it to paragraph (b). This revision is 
necessary because those operations are covered under paragraph (b). 
BSEE is also revising paragraph (e) to remove the term 
``certification'' to be consistent with other required statements and 
the use of certifications.
    Summary of comments: A commenter expressed concerns that the 
information in paragraph (a) regarding the table summarizing the 
curtailment of production and offloading is unclear and may not be 
applicable.
    Response: BSEE agrees with the commenter and is removing the 
statement ``including a table summarizing the curtailment of production 
and offloading based on operational considerations'' from paragraph (a) 
and moving it to paragraph (b). This information is more applicable to 
the contents of paragraph (b).
    Summary of comments: Multiple commenters expressed concerns with 
the use of a certification statement for compliance with Subpart H.
    Response: BSEE agrees with the commenters and has removed the term 
``certification'' from paragraph (e). BSEE will still require a 
statement that the production safety systems will comply with Subpart 
H. Subpart H contains the requirements for production safety systems 
and a certification is not necessary at this stage. BSEE wants to 
ensure that the safety system requirements are considered at this stage 
of the DWOP process.
    Summary of comments: A commenter requested that BSEE clarify if a 
description of the leak detection system or the actual procedures are 
required.
    Response: BSEE disagrees with the commenter that the language is 
unclear. The regulations in Sec.  250.240(f) require the submittal of 
information concerning both the leak detection system itself and 
procedures for how to operate the system, ensure system functionality, 
identify a leak, and the actions to take when a leak is identified.

What subsea systems and pipeline information must my DWOP include? 
(Sec.  250.241)

Summary of Proposed Rule Revisions
    BSEE proposed to identify the subsea systems and associated 
pipeline systems information that must be included in a DWOP. The 
content of paragraphs (c)(2)(i), (ii), and (iii) of this proposed 
section would be moved from current

[[Page 71099]]

Sec.  250.292. Proposed paragraph (a) would require the operator to 
identify the information common to the subsea system and the associated 
pipeline system, which constitute all or part of a single project 
development covered by the DWOP and is consistent with activities 
addressed in an associated pipeline application, and would require the 
submission of the following:

--A subsea field schematic depicting the planned subsea development 
equipment and infrastructure, including wells/trees, non-pipe subsea 
equipment, pipeline route(s), pipeline riser systems, umbilical(s), and 
platform footprint;
--A description of the subsea development project detailing the subsea 
and pipeline equipment design criteria and analysis procedures 
(including industry standards, pressure and temperature ratings, 
materials selection), testing methods, and general operational 
procedures;
--A description of the fabrication and assembly/testing location of 
subsea trees, pipelines, and non-pipe subsea equipment (manifold, 
pipeline end manifold, pipeline end termination, subsea umbilical 
termination assembly, subsea pumps, suction piles, etc.);
--A summary of the subsea tieback development technologies' Integrity 
Management Program, including a plan for inspection and monitoring to 
support assessment of system condition. This should include, but not be 
limited to, the in-service inspections or surveys of hull and topsides 
structures, tendons, moorings, and pipelines and/or wellbore riser 
systems to assess and analyze component condition after each 
significant environmental event (e.g., hurricane, earthquake, loop and 
eddy currents, or mudslide) impacting the system, or once every 10 
years, whichever occurs first; and
--A summary of safety and environmental controls.

    Proposed paragraph (b) would require submission of the following 
information about subsea systems that constitute all or part of a 
single project development covered by the DWOP, as applicable:

--System control type (i.e., direct hydraulic or electro-hydraulic);
--Well tree(s), wellhead, and non-pipe equipment general arrangement 
drawings and schematics, with size and valve type annotations to 
illustrate the tree and other equipment in operation;
--Estimated shut-in tubing pressure for the proposed well(s), including 
the calculations used to arrive at the estimate, specifying true 
vertical depth, reservoir pressure, and the fluid gradient used, or a 
brief discussion of the pressure volume temperature (PVT) data used for 
estimation;
--Wellbore static bottomhole temperature and the estimated flowing 
temperature at the tree, including a description of the method used to 
calculate this estimate;
--A description of the umbilical(s) and umbilical connection(s), 
including an umbilical cross-section schematic;
--A description of the chemical or other injection systems and/or 
enhanced recovery systems the operator plans to use;
--A description of the corrosion monitoring and prevention/inhibition 
processes;
--Details of any re-furbished and/or re-certified equipment that would 
be used; and
--A schedule of development activities, including well completion, 
facility installation, and anticipated date of first oil.

    Proposed paragraph (c) would require an operator to include 
pipeline information in its DWOP to align with the activities to be 
addressed in the associated pipeline application(s), including:

--Design and fabrication information for each pipeline riser system;
--For projects that will use a pipeline free standing hybrid riser 
(FSHR) on a permanent installation that uses a buoyancy air can 
suspended from the top of the riser, the operator would be required to 
provide the following information in its DWOP as part of the discussion 
required by paragraph (b)(1) and (2) of Sec.  250.241: a detailed 
description and drawings of the FSHR, buoy, and the associated 
connection system; detailed information regarding the system used to 
connect the FSHR to the buoyancy air can, and associated redundancies; 
and descriptions of the monitoring system and monitoring plan for the 
pipeline FSHR and the associated connection system for fatigue, stress, 
and any other abnormal condition (e.g., corrosion) that may negatively 
impact the riser system's integrity; and
--Pipeline and pipeline riser installation methods.

    Submission of this information is consistent with what BSEE 
currently requires in the DWOP (and has historically required). The 
proposed requirements would clarify general language in the existing 
regulation by adding specificity regarding scope.
Summary of Final Rule Revisions
    Based on comments received and after review of comments, BSEE is 
revising paragraph (a)(4) to clarify that the operator must also 
include in the integrity management plan a description of how it will 
determine when a significant environmental event has occurred and how 
it will respond to such an event. This revision would help identify and 
properly account for integrity management through significant 
environmental events. BSEE is also revising paragraph (c)(1) to only 
require ``general'' design and fabrication information for pipelines. 
This revision addresses a situation where some of the specific design 
and fabrication information may not be available at this stage. For the 
purposes of the DWOP, the general design and fabrication information is 
sufficient.
    Summary of comments: Multiple commenters expressed concerns that 
certain information requested in this section is duplicative with 
information covered under Conceptual Plans or the associated permits or 
applications.
    Response: BSEE disagrees with this comment. This section covers the 
DWOP submittal, which presents information from a whole project 
perspective. Conversely, Conceptual Plans focus on an individual 
component or assembly.
    Summary of comments: A commenter recommended that BSEE require that 
operators' integrity management plans state their process for 
determining significant environmental events.
    Response: BSEE agrees with the commenter and has revised paragraph 
(a)(4) to require the operator to also provide a description in the 
integrity management plan of how it will determine that significant 
environmental events have occurred, and how it will respond to such an 
event. This revision clarifies the scope of the integrity management 
plan. It is BSEE's intent to ensure that operators discuss, plan for, 
and address the impacts of the significant environmental events.
    Summary of comments: A commenter asked for clarification as to the 
source of the 10-year assessment.
    Response: Based on BSEE experience with assessing facilities or 
equipment through their entire lifecycle, the assessment cycle of 10 
years in paragraph (a)(4) of this section is an incremental approach to 
platform service life extension and monitoring. Often, operators ask 
for infinite or significant years of increased life. BSEE's approach 
has been to approve fewer years--either 5 or 10--and revisit

[[Page 71100]]

the calculations and inspection data later to ensure there are no 
significant changes. BSEE will remain consistent with that approach and 
utilize the identified assessment cycle. As BSEE gains more experience 
with the assessments, BSEE will evaluate the efficiency of the 
assessment cycle and may revise it as appropriate.
    Summary of comments: A commenter asked if the NTLs help define the 
affected area for inspections and assessments after a significant 
environmental event.
    Response: BSEE will continue to use the guidance of an NTL to help 
identify the affected area of the significant environmental event 
(e.g., see NTL No. 2021-G02). This information is very useful to focus 
the inspections and assessments to those areas potentially impacted by 
the significant environmental events.
    Summary of comments: A commenter expressed concerns that it is not 
practical to directly monitor stress and fatigue in all components. The 
commenter also stated that the assessment for stress should be 
determined based on observed responses and analytical assessment.
    Response: BSEE disagrees with the commenter's concerns and is not 
revising this section based on this comment. It is BSEE's expectations 
that the operator must identify how it will monitor the FSHR and 
associated connection system. BSEE does not want to limit how an 
operator conducts the appropriate monitoring to ensure riser system 
integrity.

What new or unusual technology information must my DWOP include? (Sec.  
250.242)

Summary of Proposed Rule Revisions
    BSEE proposed in this section to identify the new or unusual 
technology information that must be included in the DWOP, including the 
information referenced in the applicable Conceptual Plan. Proposed 
paragraph (a) would require the submission of a description of any new 
or unusual technology being used in a development project, including a 
reference to previously approved New or Unusual Technology Conceptual 
Plans or New or Unusual Technology Barrier Conceptual Plans.
    Proposed paragraph (b) would require submission of a description of 
any new or unusual technology not covered under the New or Unusual 
Technology Conceptual Plan or New or Unusual Technology Barrier 
Conceptual Plan. It would also require an operator to include the same 
applicable information as required in Sec. Sec.  250.228 or 250.229.
Summary of Final Rule Revisions
    BSEE did not receive any comments on the substance of the provision 
of this section and is finalizing the proposed revisions with 
administrative changes to reflect the revisions to the name of the New 
or Unusual Technology Barrier Equipment Conceptual Plan, as discussed 
previously in this preamble.
    Summary of comments: A commenter asked what service fee would be 
required if an operator needed to submit the description of any new or 
unusual technology not previously approved in the applicable Conceptual 
Plan.
    Response: BSEE will require the service fees listed in Sec.  
250.125 for the plans required under the DWOP Process for the specific 
project proposed.
    BSEE proposed to reserve Sec. Sec.  250.243-250.244, and these 
sections are reserved in this regulation.

May I combine the Project Conceptual Plan and the DWOP? (Sec.  250.245)

Summary of Proposed Rule Revisions
    BSEE proposed to move to this section the content from current 
Sec.  250.294, which addresses when an operator may submit a combined 
Conceptual Plan and DWOP, and proposed to include the following 
revisions:
    The introductory paragraph would be revised to clarify that, if the 
operator's development project meets the criteria in proposed 
paragraphs (a) and (b) of this section, an operator may submit a 
combined Conceptual Plan and DWOP that complies with all applicable 
requirements for both, on or before the deadline for submitting the 
Conceptual Plan, as described in proposed Sec.  250.226. Existing 
paragraph (a), which allows the operator to submit a combined 
Conceptual Plan and DWOP if the project is located in water depths of 
less than 400 meters (1,312 feet), would be removed.
    Existing paragraph (a) would be replaced with existing paragraph 
(b), which allows a combined plan if the project is similar to projects 
involving subsea tieback development technology for which the operator 
has obtained approval previously. BSEE proposed to add a new paragraph 
(b) to allow for the submission of a combined Conceptual Plan and DWOP 
if the project does not involve either new or unusual technology or a 
new platform. As previously stated at the beginning of the paragraph, 
the operator must meet the criteria in paragraph (a) and (b) of 
proposed Sec.  250.245 in order to be able to submit a combined 
Conceptual Plan and DWOP.
    These revisions would provide clarity for operators to streamline 
the process, when appropriate, and would reflect conforming edits for 
new or unusual technology. These revisions would reflect current BSEE 
acceptance of combined submission of the Conceptual Plan and DWOP in 
certain situations.
Summary of Final Rule Revisions
    BSEE received a comment on these provisions and is making a 
revision based on that comment. BSEE is changing the heading to read: 
``May I combine the Project Conceptual Plan and the DWOP?'' and is 
revising the introductory paragraph accordingly. BSEE is clarifying 
that that the ``Project'' Conceptual Plan can be combined with the 
DWOP.
    Summary of comments: A commenter suggested that BSEE add the term 
``project'' to the reference to the Conceptual Plans.
    Response: BSEE is revising this section to clarify that a Project 
Conceptual Plan may be combined with the DWOP if the project meets the 
required criteria. This revision is consistent with paragraph (b) that 
prohibits the combination of a Conceptual Plan and DWOP if the project 
involves new or unusual technology.

When must I revise my DWOP? (Sec.  250.246)

Summary of Proposed Rule Revisions
    BSEE proposed to move to this section the content from current 
Sec.  250.295 and to clarify when revision to an approved Conceptual 
Plan or DWOP is necessary. Revision is necessary when there are changes 
in the development project that alter the proposed plan or procedures, 
but that do not involve a physical alteration of the equipment on the 
platform or the seabed. As explained below, a supplement is required 
when changes involve a physical alteration of the equipment on the 
platform or the seabed. This section and the following section are 
intended to reduce confusion by helping operators determine when a 
revision or a supplement to the applicable Conceptual Plan or DWOP is 
necessary.
Summary of Final Rule Revisions
    Based on comments received and review of the comments, BSEE is 
revising this section to clarify when a revision to a DWOP is 
necessary. BSEE removed the reference to revising the Conceptual Plan 
as it is not applicable to this section and clarified that revisions 
are necessary only to the

[[Page 71101]]

approved DWOP to reflect any material change to the plan.
    Summary of comments: A commenter expressed concerns that requiring 
a revision to the plan for ``any changes'' is too broad and burdensome.
    Response: BSEE disagrees with the commenter and wants to ensure the 
information contained in the DWOP is accurate and consistent with the 
applicable approved permit or application. BSEE has clarified the 
difference between a revision and supplement and has revised the 
service fees to adequately reflect the appropriate level of actions 
necessary to complete the revision or supplement. However, BSEE also 
clarified that any material change to the plan would require a 
revision. This clarification is consistent with the language of the 
previous regulations (see previous Sec.  250.295).
    Summary of comments: A commenter expressed concerns that revisions 
to the Conceptual Plans are not applicable to this section and should 
be removed.
    Response: BSEE agrees with the commenter and is removing the 
reference to Conceptual Plan revisions. Revisions to the Conceptual 
Plans are outside the scope of this section and it is unnecessary to 
include them in this section.

When must I supplement my DWOP? (Sec.  250.247)

Summary of Proposed Rule Revisions
    BSEE proposed in this section to identify when an operator must 
supplement the approved DWOP to reflect additions or changes in the 
development project.
    Proposed paragraph (a) would require the operator to submit a 
supplement to the DWOP to reflect any additions or changes in the 
development project that physically alter the platform, process 
facilities, equipment, or systems approved in the original Conceptual 
Plan or DWOP. If a Supplemental DWOP proposes the addition of any wells 
(e.g., a new subsea field) not approved in the original DWOP, the 
operator may not complete or produce from the new well(s) until BSEE 
approves the Supplemental DWOP.
    Proposed paragraph (b) would require a supplement to the DWOP for 
additions or changes that involve the addition of any new or unusual 
technology to the project that was not previously approved under the 
New or Unusual Technology Conceptual Plan, New or Unusual Technology 
Barrier Conceptual Plan, or DWOP. This proposed paragraph would also 
clarify that the operator may not install any new or unusual technology 
until BSEE approves the Supplemental DWOP.
    This section would be added to clarify when operators must submit 
supplemental DWOPs. This section and the section above are intended to 
reduce confusion by helping operators determine when a revision or a 
supplement to the DWOP is necessary.
Summary of Final Rule Revisions
    Based on comments received and review of the comments, BSEE is 
revising paragraph (a) by removing the references to ``platform'' and 
``process facilities'' from the list of items that, if physically 
altered, would require a supplement to the DWOP and then clarifying 
that it applies to equipment or systems upstream of the boarding 
shutdown valve approved in the DWOP. BSEE is also removing the 
reference of supplementing the DWOP based on the equipment and systems 
approved in the original Conceptual Plan as it is not applicable to 
this section.
    BSEE is also revising paragraph (b) to clarify that under the 
situation where there is an addition of new or unusual technology not 
previously covered under an applicable Conceptual Plan or DWOP, an 
operator may not install any new or unusual technology until BSEE 
approves the applicable Conceptual Plan and supplemental DWOP. This 
revision is necessary to ensure the new or unusual technology follows 
the appropriate process including the applicable Conceptual Plan 
approval.
    Summary of comments: Multiple commenters expressed concerns that 
the language describing a supplement to the DWOP is too broad and needs 
clarification concerning when a supplement is required.
    Response: BSEE agrees in part with the commenters and is revising 
this section to clarify when a supplement to the DWOP is required by 
removing the references to ``platform'' and ``process facility'' and 
clarifying that a supplement requirement applies only when there is a 
physical change to the equipment or systems upstream of the boarding 
shutdown valve. This clarification establishes when a supplemental DWOP 
is necessary based on the scope of the equipment listed. For example, 
BSEE would not expect a supplement of your DWOP for changing decking on 
a platform.

What information must I include in my Supplemental DWOP? (Sec.  
250.248)

Summary of Proposed Rule Revisions
    BSEE proposed to describe the information that must be included in 
the supplement to the DWOP referenced in proposed Sec.  250.247.
    Proposed paragraph (a) would require the same information for the 
wells or equipment as required in the applicable Conceptual Plan and 
DWOP requirements in Subpart B. This addition would ensure consistency 
between the initial and supplemental submissions.
    Proposed paragraph (b) would describe information for each 
applicable Conceptual Plan or DWOP section that is being impacted by 
the addition or change.
    Proposed paragraph (c) would require documents demonstrating 
payment of the new service fee for BSEE's review and processing of a 
supplemental DWOP, as listed in the proposed revisions to Sec.  
250.125.
Summary of Final Rule Revisions
    BSEE did not receive any comments on the content of this section 
and is finalizing the provision as proposed.

Subpart D--Oil and Gas Drilling Operations

Hydrogen sulfide (Sec.  250.490)

Summary of Proposed Rule Revisions
    BSEE proposed to revise paragraph (p) of this section, which 
addresses metallurgical properties of equipment used in an 
H2S environment. BSEE proposed revising the paragraph to 
state that if operating in a zone with H2S present or when 
the concentration of H2S in the produced fluid may exceed 
0.05 pounds per square inch (psi) partial pressure of H2S, 
the operator must use equipment that is constructed of materials with 
metallurgical properties that resist or prevent sulfide stress cracking 
(also known as hydrogen embrittlement, stress corrosion cracking, or 
H2S embrittlement), chloride-stress cracking, hydrogen-
induced cracking, and other failure modes.
    BSEE also proposed to revise this section to be consistent with the 
requirements of NACE Standard MR0175-2003, ``Standard Material 
Requirements, Metals for Sulfide Stress Cracking and Stress Corrosion 
Cracking Resistance in Sour Oilfield Environments, ''Revised January 
17, 2003, incorporated by reference at existing Sec. Sec.  250.490 and 
250.901 and NTL 2009-G31. Section 250.490 paragraph (p) currently 
requires that the tubing and casing be designed for NACE requirements, 
but incorrectly refers only to ``H2S present'' as the 
concentration necessary to trigger this requirement. ``H2S 
present'' is defined in existing Sec.  250.490 paragraph (b) as ``could 
potentially result in atmospheric concentration of 20 ppm or more of 
H2S.'' BSEE proposed language to clarify

[[Page 71102]]

that in either ``H2S present'' conditions or when 
H2S concentrations in the produced fluid exceed 0.05 psi 
partial pressure of H2S, the operator must use equipment 
that is constructed of materials with certain metallurgical properties, 
in accordance with NACE Standard MR0175-2003.
Summary of Final Rule Revisions
    BSEE is including the proposed language in the final rule without 
change.
    Summary of comments: A commenter recommended that BSEE reference 
NACE MR0175 in the introductory text to paragraph (p).
    Response: BSEE is not including the reference to NACE MR0175 in the 
introductory text to this paragraph in the final rule because it is 
currently referenced in existing paragraph (p)(2). BSEE already 
requires BOP system components, wellhead, pressure-control equipment, 
and related equipment exposed to H2S-bearing fluids to be in 
conformance with NACE Standard MR0175. BSEE also requires conformance 
with NACE MR0175 in other subparts of the BSEE regulations as it 
pertains to other equipment (e.g., see Sec. Sec.  250.518(a)(2) and 
250.619(a)(2) for tubing requirements).

Subpart E--Oil and Gas Well-Completion Operations

Tubing and wellhead equipment (Sec.  250.518)

Summary of Proposed Rule Revisions
    BSEE proposed to revise paragraph (a) of Sec.  250.518 to include 
the following:

--The tubing string must be evaluated for burst, collapse, and axial 
loads with appropriate safety and design factors for the pressure and 
temperature environments of the completion, production, shut-in, and 
injection load cases;
--The tubing string materials must be appropriate for the environment. 
The operator must follow NACE Standard MR0175-2003 (as incorporated by 
reference in Sec.  250.198) when H2S concentration may equal 
or exceed 0.05 psi partial pressure; and
--The tubing string threaded connectors must be appropriate for the 
loads identified in proposed paragraph (a)(1).

    These revisions would reflect essential well design elements 
addressed in industry standards. Current regulations discuss well 
design specific to casing, but little is provided for tubing design, 
which is equally critical for well integrity. Regulations currently 
establish H2S concentrations that constitute a specific 
threat to personnel and establish concentrations that trigger enactment 
of H2S protocols. Additional requirements added to this 
section would address H2S impacts to equipment integrity, as 
these components must function as barriers to personnel and the 
environment. Section 250.490 paragraph (p) currently requires that the 
tubing and casing be designed for NACE requirements, but incorrectly 
refers only to ``H2S present'' as the concentration 
necessary to trigger this requirement. ``H2S present'' is 
defined in existing Sec.  250.490 paragraph (b) as ``could potentially 
result in atmospheric concentration of 20 ppm or more of 
H2S.'' BSEE proposed to clarify that, in either 
``H2S present'' conditions or when H2S 
concentrations in the produced fluid exceed 0.05 psi partial pressure 
of H2S, the operator must use equipment that is constructed 
of materials with certain metallurgical properties, in accordance with 
NACE Standard MR0175-2003.
    BSEE also proposed to revise paragraph (c) of this section to 
include the design and testing of the wellhead, tree, and related 
equipment in accordance with ANSI/API Spec. 6A (as incorporated by 
reference in Sec.  250.198) or ANSI/API Spec. 17D (as incorporated by 
reference in Sec.  250.198), as applicable. The proposed rule would 
also add paragraphs (c)(1), (2), and (3) to clarify that:

--Newly completed dry trees (e.g., fixed, hybrid, or mudline 
suspension) for production or injection wells must be equipped with a 
minimum of one master valve and one surface safety valve (SSV), 
installed above the master valve, in the vertical run of the tree;
--Newly completed subsea production or injection wells must be equipped 
with a minimum of one USV installed in the horizontal or vertical run 
of the tree (e.g., vertical or horizontal subsea trees); and
--Newly completed wells with a mudline suspension conversion to a 
subsea tree must have a minimum of two casing strings tied back and 
sealed below the tubing head. At a minimum, the production casing and 
the next outer casing must be tied back to the wellhead to ensure 
annular isolation.

    BSEE proposed adding paragraph (c)(3) because ANSI/API Spec. 17D 
does not address mudline suspension conversion to a subsea tree with 
more than one casing tieback. The proposed revisions would also codify 
similar language from NTL 2006 G-20, which would establish a 
requirement for a minimum of two casing strings tied back and sealed 
below the tubing head for a mudline suspension conversion to a subsea 
tree.
    BSEE proposed revising paragraph (d) to clarify that both the 
subsurface safety equipment and surface safety equipment must comply 
with applicable requirements of Subpart H.
Summary of Final Rule Revisions
    BSEE received a comment on this section, but is not making any 
revisions based on that comment. BSEE is finalizing the proposed 
content with a clarification in paragraph (a)(1) that the tubing string 
must be evaluated with appropriate safety factors and material design 
factors. This revision clarifies this regulation with the correct usage 
of terms for engineering analysis.
    Summary of comments: A commenter expressed concerns that certain 
content in this section is redundant of the requirements of Subpart D 
and should be removed.
    Response: BSEE disagrees with the commenter and is not removing the 
content. Finalizing the regulation based on the proposed language helps 
ensure consistency among the different subparts and considerations for 
operations when H2S is present.

Subpart F--Oil and Gas Well-Workover Operations

Tubing and wellhead equipment (Sec.  250.619)

Summary of Proposed Rule Revisions
    BSEE proposed to revise paragraph (a) of Sec.  250.619 to include 
the following:

--The tubing string must be evaluated for burst, collapse, and axial 
loads with appropriate safety and design factors for the pressure and 
temperature environments of the completion, production, shut-in, and 
injection load cases;
--The tubing string materials must be appropriate for the environment. 
The operator must follow NACE Standard MR0175-2003 (as incorporated by 
reference in Sec.  250.198) when H2S concentration may equal 
or exceed 0.05 psi partial pressure; and
--The tubing string threaded connectors must be appropriate for the 
loads identified in proposed paragraph (a)(1).

    Additional requirements BSEE proposed to add to this section 
address H2S impacts to equipment integrity, as these 
components must function as barriers to personnel and the environment. 
BSEE proposed to clarify that in either ``H2S present'' 
conditions or when H2S concentrations in the

[[Page 71103]]

produced fluid exceed 0.05 psi partial pressure of H2S, the 
operator must use equipment that is constructed of materials with 
certain metallurgical properties, in accordance with NACE Standard 
MR0175-2003.
    BSEE also proposed to revise paragraph (c) to include the design 
and testing of the wellhead, tree, and related equipment in accordance 
with ANSI/API Spec. 6A (as incorporated by reference in Sec.  250.198) 
or ANSI/API Spec. 17D (as incorporated by reference in Sec.  250.198), 
as applicable. This section would also add paragraphs (c)(1), (2), and 
(3) to clarify that:

--Newly completed dry trees (e.g., fixed, hybrid, or mudline 
suspension) for production or injection wells must be equipped with a 
minimum of one master valve and one SSV, installed above the master 
valve, in the vertical run of the tree;
--Newly completed subsea production or injection wells must be equipped 
with a minimum of one USV installed in the horizontal or vertical run 
of the tree (for vertical or horizontal subsea trees); and
--Newly completed wells with a mudline suspension conversion to a 
subsea tree must have a minimum of two casing strings tied back and 
sealed below the tubing head. At a minimum, the production casing and 
the next outer casing must be tied back to the wellhead, to ensure 
annular isolation.

    BSEE proposed to revise paragraph (d) to clarify that surface 
safety equipment must be installed, maintained, and tested in 
accordance with applicable sections of Subpart H, in addition to the 
subsurface safety equipment.
Summary of Final Rule Revisions
    BSEE did not receive any comments on this section and is finalizing 
the proposed content with the same clarification identified in Sec.  
250.518 in paragraph (a)(1) that the tubing string must be evaluated 
with appropriate safety factors and material design factors. This 
revision clarifies this regulation with the correct usage of terms for 
engineering analysis and is consistent with similar requirements in 
Sec.  250.518.

Subpart G--Well Operations and Equipment

What information must I submit for BOP systems and system components? 
(Sec.  250.731)

Summary of Proposed Rule Revisions
    BSEE proposed to revise existing paragraph (c)(4) of Sec.  250.731 
to update a cross-reference to the definition of HPHT in accordance 
with proposed Sec.  250.105.
Summary of Final Rule Revisions
    BSEE did not receive any comments on this provision of the proposed 
rule and is including the proposed language in the final rule without 
change.

What are the independent third party requirements for BOP systems and 
system components? (Sec.  250.732)

Summary of Proposed Rule Revisions
    BSEE proposed to revise existing paragraph (c) of Sec.  250.732 to 
reflect the addition of the new or unusual technology and new or 
unusual technology barrier requirements in Subpart B. BSEE proposed to 
delete the independent third-party requirements under existing 
paragraph (c) because that information would be covered under the new 
DWOP process requirements. These proposed revisions would connect the 
HPHT permitting (e.g., APD) requirements and the DWOP process 
requirements and would improve BSEE's review and decision process. BSEE 
proposed these revisions to help ensure that the specified equipment is 
fit for service in the environmental conditions reasonably expected at 
the operation's site.
    BSEE also proposed to remove duplicative requirements now covered 
under the DWOP new or unusual technology barrier requirements and would 
provide greater detail considering that the Conceptual Plan review 
occurs before use of HPHT equipment and would occur before application 
review. BSEE proposed to consolidate the language and refer to the 
applicable new or unusual technology barrier requirements and would 
specify that BSEE would require Conceptual Plan and appropriate permit 
approval before equipment installation. This addition would provide 
clarification to operators unfamiliar with the applicable DWOP 
requirements.
Summary of Final Rule Revisions
    Based on comments received and review of the comments, BSEE is 
revising paragraphs (c)(4) and (c)(5) to remove the term 
``certification'' to be consistent with other required statements and 
the use of certifications. BSEE is also revising paragraph (c) to 
clarify that the operator may not deploy the proposed BOP system and 
related equipment that will or may be exposed to an HPHT environment 
until BSEE approves the appropriate Conceptual Plan and permits (e.g., 
APD and APM). This clarification helps ensure the correct use of 
terminology and description of equipment or systems. For example, BSEE 
does not have a definition of ``HPHT BOP system,'' so that term was 
removed.
    BSEE also fixed incorrect cross references throughout this section 
based on the updates to Subpart B.
    Summary of comments: Multiple commenters expressed concerns with 
the use of the term ``related equipment'' as it relates to BOP systems 
and asserted that this section is limited to BOP equipment.
    Response: BSEE disagrees with the commenters, as ``BOP systems and 
related equipment'' has been defined in Sec.  250.105, and BSEE is not 
making changes to this section based on this comment. BSEE defines 
``BOP systems and related equipment'' to be all pressure controlling 
and pressure containing well control equipment that may or will be 
exposed to the well's MASP during drilling, completion, workover, 
intervention, or abandonment. Well control equipment includes equipment 
that is installed for the purpose of pressure control and pressure 
containment when it becomes necessary to physically enter a well bore 
during drilling, completion, workover, intervention, or abandonment 
modes of operation. This definition makes it clear what is included in 
``BOP systems and related equipment.''
    Summary of comments: A commenter expressed concerns that it is 
unclear how MASP is determined for all the stated operations and 
requested BSEE clarify how to determine MASP.
    Response: BSEE disagrees with the commenter and is not making 
changes to this section based on this comment. Information regarding 
how to determine MASP is already identified in multiple BSEE 
regulations (e.g., see Sec.  250.730).
    Summary of comments: Multiple commenters expressed concerns with 
the use of a certification statement for compliance with Subpart H.
    Response: BSEE agrees with the commenters and has removed the term 
``certification'' from paragraph (c). BSEE will still require a 
statement in accordance with Sec. Sec.  250.230 and 250.232. BSEE wants 
to ensure consistency with the use of I3P statements.
    Summary of comments: A commenter requested clarification about when 
the Conceptual Plans are required for HPHT operations discussed in this 
section.
    Response: BSEE has determined that no clarification is needed in 
this section. As stated in this section, the operator cannot deploy the 
proposed HPHT BOP system and related equipment until BSEE approves the 
New or Unusual Technology Barrier

[[Page 71104]]

Equipment Conceptual Plan and appropriate permit. Also, BSEE requires 
certain actions listed in paragraph (c) before beginning any operation 
in an HPHT environment. If the operations are not in an HPHT 
environment as defined by BSEE, then paragraph (c) is not applicable. 
This section is only applicable to operations in an HPHT environment 
and all non-HPHT new or unusual technology will need to follow the New 
or Unusual Technology Barrier Equipment Conceptual Plan process in 
Subpart B.

Subpart H--Oil and Gas Production Safety Systems

Additional Requirements for Subsurface Safety Valves (SSSVs) and 
Related Equipment Installed in High Pressure High Temperature (HPHT) 
Environments (Sec.  250.804)

Summary of Proposed Rule Revisions
    BSEE proposed to remove and reserve this section. The existing 
requirements from this section would be addressed under proposed 
Sec. Sec.  250.105 and 250.204.
Summary of Final Rule Revisions
    BSEE did not receive any comments on this proposed section and is 
finalizing the proposed removal and reservation of this section without 
change.

V. Procedural Matters

Regulatory Planning and Review (Executive Orders (E.O.) 12866, 14094, 
and 13563).

    E.O. 12866, Regulatory Planning and Review, as amended by E.O. 
14094, provides that OMB's Office of Information and Regulatory Affairs 
(OIRA) will review all significant regulatory actions. A significant 
regulatory action is one that is likely to result in a rule that:
     Has an annual effect on the economy of $200 million or 
more (adjusted every 3 years by the Administrator of OIRA for changes 
in gross domestic product); or adversely affect in a material way the 
economy, a sector of the economy, productivity, competition, jobs, the 
environment, public health or safety, or State, local, territorial, or 
tribal governments or communities;
     Creates a serious inconsistency or otherwise interferes 
with an action taken or planned by another agency;
     Materially alters the budgetary impacts of entitlement 
grants, user fees, loan programs or the rights and obligations of 
recipients thereof; or
     Raises legal or policy issues for which centralized review 
would meaningfully further the President's priorities or the principles 
set forth in E.O. 12866, as specifically authorized in a timely manner 
by the Administrator of OIRA in each case.
    OIRA has determined that this final rule is not significant under 
E.O. 12866.
    In support of that conclusion, BSEE prepared a final Regulatory 
Impact Analysis (RIA) to assess the anticipated costs and potential 
benefits of the rulemaking. The RIA estimates that the increase in 
annualized costs, compared with the baseline in the absence of the 
proposed rule, is $6.6 million per year. Over the period 2025-2034, 
those costs are estimated to have a total present value of $64.0 
million undiscounted, $57.5 million discounted at 2 percent, and $59.3 
million discounted at 2 percent with a capital displacement adjustment. 
The RIA for this rulemaking can be found in the docket at https://www.regulations.gov/ (Docket ID: BSEE-2021-0003).
    As required by the Independent Offices Appropriation Act (IOAA), as 
amended (31 U.S.C. 9701), the rule will establish new fees for BSEE's 
review and processing of several types of operator submissions and 
reports. This rule will add service fees for processing a Project 
Conceptual Plan, New or Unusual Technology Conceptual Plan, New or 
Unusual Technology Barrier Equipment Conceptual Plan, revised DWOP, 
Combined Conceptual Plan/DWOP, and Revised or Supplemental DWOP. This 
rule will also revise the cost recovery fee amount for DWOP review. The 
final rule will increase, and not adversely affect, the government's 
receipt of user fees. BSEE's economic analysis projects that, 
altogether, the fees anticipated to be collected under the proposal 
over a 10-year period (2025-2034) would exceed the baseline fees 
collected by approximately $1.6 million (undiscounted).
    The rulemaking will improve operational and environmental safety 
and human health for deepwater development projects and other projects 
or systems that use new or unusual technology, not only by providing 
clarity and regulatory certainty regarding the information submission 
process, but also by ensuring that additional regulatory requirements 
and that New or Unusual Technology Barrier Equipment Conceptual Plans 
are reviewed by I3Ps, as well as providing BSEE discretion to require 
I3P review of New or Unusual Technology Conceptual Plans. BSEE has not 
monetized or quantified the benefits of the new submission process, the 
new requirements for new or unusual technology projects, including HPHT 
projects, and I3P reviews. BSEE believes that by updating references to 
industry standards and giving greater clarity to requirements for 
submissions for new or unusual technology and HPHT projects and plans, 
the final rule promotes the objectives of E.O. 13563, including a 
reasoned determination that its benefits justify its costs (recognizing 
that some benefits and costs are difficult to monetize or quantify).
    Executive Order 13563, Improving Regulation and Regulatory Review, 
reaffirms the principles of E.O. 12866 while calling for improvements 
in the Nation's regulatory system to promote predictability, to reduce 
uncertainty, and to use the best, most innovative, and least burdensome 
tools for achieving regulatory ends. E.O. 13563 directs agencies to 
consider regulatory approaches that reduce burdens and maintain 
flexibility and freedom of choice for the public where these approaches 
are relevant, feasible, and consistent with regulatory objectives. E.O. 
13563 emphasizes further that regulations must be based on the best 
available science and that the rulemaking process must allow for public 
participation and an open exchange of ideas. We have developed this 
final rule in a manner consistent with these requirements.

Regulatory Flexibility Act

    The Regulatory Flexibility Act (RFA), 5 U.S.C. 601-612, requires 
agencies to analyze the economic impact of regulations when there is 
likely to be a significant economic impact on a substantial number of 
small entities and allows an agency to certify a rule, in lieu of 
preparing an analysis, if the regulation will not have such an economic 
impact.
    BSEE considers a rule to have an impact on a ``substantial number 
of small entities'' when the total number of small entities impacted by 
the rule is equal to or exceeds 10 percent of the relevant universe of 
small entities in a given industry. The relevant small-size criteria 
for affected operators and firms likely to help prepare reports are 
presented in Table 1 below.

[[Page 71106]]



            Table 1--Small-Entity Criteria for Affected Firms
------------------------------------------------------------------------
               Industry sector                   Small-entity criteria
------------------------------------------------------------------------
211120 Crude petroleum extraction............  1,250 employees.
211130 Natural gas extraction................  1,250 employees.
213111 Drilling oil and gas wells............  1,000 employees.
541330 Engineering services (for the I3P or    $16.5 million/year
 other reports).                                revenues.
------------------------------------------------------------------------

    Using these criteria, BSEE estimates that the final rule will 
affect about 23 companies over the next 10 years (2025-2034), of which 
approximately 12 (52 percent) of the potentially impacted businesses 
are considered small; the rest are considered large businesses. All of 
the operating businesses meeting the U.S. Small Business Administration 
classification are potentially impacted; therefore, BSEE expects that 
the rule will affect a substantial number of small entities.
    As noted in the E.O. 12866 discussion, the final rule will result 
in increased costs to firms from HPHT and new or unusual technology 
reporting requirements and increased service fees, including mandatory 
I3P nominations and reports. The increase in cost borne by industry 
includes cost of submissions, preparation, and cost recovery fees. BSEE 
has evaluated quantifiable costs and benefits and has estimated that 
there are quantified costs to industry from the final provisions. BSEE 
has estimated the annualized industry costs by business size in Table 
2. The percent of the total industry cost impacts to small operators 
was estimated based on their percentage of overall revenues. These 
revenues were estimated by applying Census Statistics of U.S. 
Businesses revenue estimates by employment ranges to each impacted 
operator. Based on historical information, BSEE estimates that small 
companies will bear 8 percent of the industry costs from this rule and 
large companies will bear the remaining 92 percent.

                  Table 2--Total 10-Year Industry Costs Associated With Final Rule (2025-2034)

----------------------------------------------------------------------------------------------------------------
Small Companies...........................................                        8                     $505,733
Large Companies...........................................                       92                    5,812,764

    Total.................................................                      100                    6,318,497
----------------------------------------------------------------------------------------------------------------

    Table 3 presents the average industry cost and revenue per firm and 
the numbers of firms classified as small or large. This is presented in 
Table 3, which illustrates that on a per-firm basis the new reporting 
costs that will be imposed on small firms by the new requirements, at 
$42,123 per year, will represent approximately 0.015 percent of 
revenue. BSEE uses a threshold of 1 percent of annual revenues to 
determine the significance of costs on entities; therefore, the new 
reporting costs are not deemed to be a significant impact. BSEE 
therefore projects that the final rule is not likely to have a 
significant economic impact on a substantial number of small entities. 
Although it is not likely required because of this projection, BSEE has 
conducted a regulatory flexibility analysis (RFA), which provides 
information on the impact of the final rule on small entities. It is 
contained in the RIA, which can be found in the docket at https://www.regulations.gov/ (Docket ID: BSEE-2021-0003).

Unfunded Mandates Reform Act of 1995

    This final rule would not impose an unfunded mandate on State, 
local, or tribal governments or the private sector of more than $195 
million per year. The final rule will not have a significant or unique 
effect on State, local, or tribal governments or the private sector. A 
statement containing the information required by Unfunded Mandates 
Reform Act (2 U.S.C. 1531 et seq.) is not required.

Takings Implication Assessment (E.O. 12630)

    Under the criteria in E.O. 12630, this final rule does not have 
significant takings implications. The rule is not a governmental action 
capable of interference with constitutionally protected property 
rights. A Takings Implication Assessment is not required.

Federalism (E.O. 13132)

    Under the criteria in E.O. 13132, this final rule does not have 
federalism implications. This final rule will not substantially and 
directly affect the relationship between the Federal and State 
governments. To the extent that State and local governments have a role

[[Page 71107]]

in OCS activities, this final rule will not affect that role. A 
federalism assessment is not required.

Civil Justice Reform (E.O. 12988)

    This final rule complies with the requirements of E.O. 12988. 
Specifically, this rule:
    (1) Meets the criteria of section 3(a) requiring that all 
regulations be reviewed to eliminate errors and ambiguity and be 
written to minimize litigation; and
    (2) Meets the criteria of section 3(b)(2) requiring that all 
regulations be written in clear language and contain clear legal 
standards.

Consultation With Indian Tribes (E.O. 13175)

    BSEE strives to strengthen its government-to-government 
relationships with Tribal Nations and Alaska Natives through a 
commitment to consultation with the Tribes and recognition of their 
right to self-governance and Tribal sovereignty. BSEE is also 
respectful of its responsibilities for consultation with Alaska Native 
Claims Settlement Act (ANCSA) Corporations. In 2022, BSEE notified 
Tribal Nations and ANCSA Corporations of multiple BSEE rulemakings in 
development, including this final rule, and invited further government-
to-government consultations on any subjects in the regulatory agenda at 
a Tribe's or ANCSA Corporation's request. BSEE received written 
comments on the regulatory agenda from the Mashpee Wampanoag Tribe, 
Native Village of Kotzebue, and Choctaw Nation of Oklahoma, and held a 
subsequent informational meeting with the Choctaw Nation of Oklahoma. 
None of the Tribes submitted comments or requested further 
consultations pertaining to this final rule. Under the criteria in E.O. 
13175 and DOI's Policies on Consultation with Indian Tribes and 
Consultation with Alaska Native Claims Settlement Act Corporations (512 
DM 4 and 512 DM 6, respectively), we have evaluated this final rule and 
determined that it has no substantial direct effects on federally 
recognized Indian Tribes.

National Technology Transfer and Advancement Act (NTTAA)

    BSEE complies with the National Technology Transfer and Advancement 
Act (NTTAA) (15 U.S.C. 3701 et seq.) requirement that an agency ``use 
standards developed or adopted by voluntary consensus standards bodies 
rather than government-unique standards, except where inconsistent with 
applicable law or otherwise impractical.'' (OMB Circular A-119 at p. 
13). BSEE also complies with the Office of the Federal Register (OFR) 
regulations governing incorporation by reference. (See, 1 CFR part 51.) 
Those regulations also specify the process for updating an incorporated 
standard at 1 CFR 51.11(a), and BSEE complies with those requirements, 
including seeking approval by OFR for a change to a standard 
incorporated by reference in a final rule.

Paperwork Reduction Act (PRA) of 1995

    This final rule contains existing and new information collection 
(IC) requirements for regulations at 30 CFR part 250, subpart B, Plans 
and Information, and submission to the OMB for review under the 
Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.) is required. 
Therefore, BSEE will submit an IC request to OMB for review and 
approval and request a new OMB control number. Once the 1014-AA49 final 
rule is effective, we will discontinue the hour burdens and non-hour 
cost burdens from current 1014-0024 (22,458 hours, $32,391 non-hour 
cost burden, expiration December 31, 2024), 30 CFR part 250, subpart B, 
Plans and Information. BSEE will keep the new number associated with 
this rulemaking. We may not conduct or sponsor, and you are not 
required to respond to, a collection of information, unless it displays 
a currently valid OMB control number.
    The final regulations will establish new and/or revise current 
requirements in Subpart B, Plans and Information, by revising 
regulations regarding the Deepwater Operations Plan (DWOP) Process and 
information submittal and approval process, which includes Conceptual 
Plans and DWOPs; adding requirements for HPHT barrier equipment and 
systems and new or unusual technology; and requiring, or providing BSEE 
with the option to require, independent third-party reviews of 
Conceptual Plans and DWOPs.
    This final rule revises all the proposed service fees listed in 
Sec.  250.125(a)(2) to reflect the revised processes more accurately, 
as identified in the other applicable discussions in Section III of 
this preamble and the estimated BSEE review time for the listed 
services.
    The following provides a breakdown of the paperwork hour burdens 
and non-hour cost burdens for this final rule. While some sections are 
being moved from existing Subpart B requirements, it is noted that the 
burden in proposed Sec.  250.210 (current Sec.  250.282) is covered 
under BOEM's 1010-0151. Accordingly, new burdens for BSEE are being 
added.
    As discussed in the Section-by-Section analysis above, and in the 
supporting statement available at RegInfo.gov, this rule will add/
revise:
    [New requirements, due to the final rule, are shown in bold]

    250.245--This section will be revised and moved from existing Sec.  
250.294. It will be revised to clarify that operators may submit a 
combined Project Conceptual Plan/DWOP, with all applicable requirements 
for both, on or before the deadline for submitting the Conceptual Plan 
(+428 burden hours and $27,712 non-hour costs burden).
    250.246--This section will be revised and moved from existing Sec.  
250.295. It will be revised to clarify when a revision to a Conceptual 
Plan or DWOP is necessary (+80 burden hours and $1,926 non-hour costs 
burden).
    250.247; 250.248--This section is new and will identify when an 
operator must supplement the DWOP to reflect additions or changes in 
the development project and will add the required information that must 
be included in the supplement to the DWOP. It will also require a 
supplement to the DWOP when a project change involves the addition of 
any new or unusual technology that was not previously covered under the 
New or Unusual Technology Conceptual Plan, New or Unusual Technology 
Barrier Equipment Conceptual Plan, or DWOP (+3,990 burden hours and 
$756,210 non-hour costs burden).
    This rule also edits and updates citations to Sec. Sec.  250.731(c) 
and 250.732(c). No burden changes are being requested.

    Title of Collection: 30 CFR part 250, subpart B, Plans and 
Information.
    OMB Control Number: 1014-0032.
    Form Number: None.
    Type of Review: New.
    Respondents/Affected Public: Potential respondents comprise Federal 
OCS oil, gas, and sulfur lessees/operators and holders of pipeline 
rights-of-way.
    Total Estimated Number of Annual Respondents: Currently there are 
approximately 555 Federal OCS oil, gas, and sulfur lessees and holders 
of pipeline rights-of-way. Not all the potential respondents will 
submit information at any given time, and some may submit multiple 
times.
    Total Estimated Number of Annual Responses: 374.
    Estimated Completion Time per Response: Varies from 15 minutes to 
980 hours depending on activity.
    Total Estimated Number of Annual Burden Hours: 36,168.
    Respondent's Obligation: Responses are mandatory.
    Frequency of Collection: Generally, on occasion and as required in 
the regulations.
    Total Estimated Annual Non-hour Burden Cost: $4,978,612.
    In addition, the PRA requires agencies to estimate the total annual 
reporting and recordkeeping non-hour cost burden resulting from the 
collection of information, and we solicit your comments on this item. 
For reporting and recordkeeping only, your response should split the 
cost estimate into two components: (1) total capital and startup cost 
component; and (2) annual operation, maintenance, and purchase of 
service component. Your estimates should consider the cost to generate, 
maintain, and disclose or provide the information. You should describe 
the methods you use to estimate major cost factors, including system 
and technology acquisition, expected useful life of capital equipment, 
discount rate(s), and the period over which you incur costs. Generally, 
your estimates should not include equipment or services purchased: (1) 
before October 1, 1995; (2) to comply with requirements not associated 
with the information collection; (3) for reasons other than to provide 
information or keep records for the Government; or (4) as part of 
customary and usual business or private practices.
    As part of our continuing effort to reduce paperwork and respondent 
burdens, we invite the public and other Federal agencies to comment on 
any aspect of this information collection, including:
    (1) Whether the collection of information is necessary, including 
whether the information will have practical utility;
    (2) The accuracy of our estimate of the burden for this collection 
of information;
    (3) Ways to enhance the quality, utility, and clarity of the 
information to be collected; and
    (4) Ways to minimize the burden of the collection of information on 
respondents.
    Send your comments and suggestions on this information collection 
by the date indicated in the DATES section to the Desk Officer for the 
Department of the Interior at OMB-OIRA at (202) 395-5806 (fax) or via 
the RegInfo.gov portal (online). You may view the information 
collection request(s) at http://www.reginfo.gov/public/do/PRAMain. 
Please provide a copy of your comments to the BSEE Information 
Collection Clearance Officer (see the ADDRESSES section). You may 
contact Kye Mason, BSEE Information Collection Clearance Officer at 
[email protected] with any questions. Please reference Final Rule 
1014-AA49, Oil and Gas and Sulfur Operations in the Outer Continental 
Shelf--30 CFR part 250, subpart B, Plans and Information (OMB Control 
No. 1014-0032), in your comments.

National Environmental Policy Act of 1969 (NEPA)

    BSEE determined that this action is covered under a Categorical 
Exclusion as defined by NEPA at 43 CFR 46.205. Pursuant to 43 CFR 
46.210(i) and 516 Departmental Manual 15.4(C)(1), BSEE determined that 
the final action is categorically excluded from detailed review under 
NEPA (42 U.S.C. 4321 et seq.). BSEE has determined that the final rule 
meets the criteria set forth at 43 CFR 46.210(i) for a Departmental 
Categorical Exclusion in that this final rule is ``of an 
administrative, financial, legal, technical, or procedural nature. . . 
.'' Further, BSEE has determined that the final rule does not involve 
any of the extraordinary circumstances listed in 43 CFR 46.215 that 
would require further analysis under NEPA. The final rule is an 
administrative change and does not authorize any activities on the OCS. 
It involves the review of Conceptual Plans and specialized requirements 
associated with deepwater needs (e.g., special moorings, fittings, 
production equipment, HPHT items, etc.); however, actual approval of 
Conceptual Plans and DWOPs is for administrative purposes and does not 
directly lead to OCS activity that can result in environmental impacts. 
The Conceptual Plans and DWOPs only lead to an action once they are 
included and addressed in an Exploration Plan (EP), Development 
Operations Coordination Document (DOCD), or Development and Production 
Plan (DPP) and subsequent permit applications. EPs, DOCDs, DPPs,

[[Page 71111]]

as well as the subsequent well and facility permit applications, are 
reviewed under site-specific NEPA analyses. Only EPs, DOCDs, and DPPs 
include the detailed information to fully assess future environmental 
impacts. If an operator chooses to modify their Conceptual Plans, 
DWOPs, or proposed technology or submit a new one for an activity that 
has already been reviewed and approved under the respective EP, DOCD, 
or DPP, then the operator must submit a revised EP, DOCD, or DPP in 
accordance with 30 CFR 550.283, which may trigger additional NEPA 
analysis.

Data Quality Act

    In developing this rule, we did not conduct or use a study, 
experiment, or survey requiring peer review under the Data Quality Act 
(Pub. L. 106-554, app. C, sec. 515, 114 Stat. 2763, 2763A-153-154).

Effects on the Nation's Energy Supply (E.O. 13211)

    This final rule is not a significant energy action under the 
definition in E.O. 13211 and it is not likely to have a significant 
adverse effect on the supply, distribution, or use of energy. A 
Statement of Energy Effects is not required.

Severability

    If a court holds any section or paragraph of this rule or their 
applicability to any person or circumstance invalid, the remainder of 
this rule and their applicability to other persons or circumstances 
will not be affected.

containment when it becomes necessary to physically enter a well bore 
during drilling, completion, workover, intervention, or abandonment 
modes of operation.
* * * * *
    HPHT environment means when one or more of the following well 
conditions exist:
    (1) The drilling, completion, workover, intervention, injection, 
production, or abandonment of the well requires pressure controlling or 
pressure containing equipment, including well control equipment, 
assigned a pressure rating greater than 15,000 psia or a temperature 
rating greater than 350 degrees Fahrenheit;
    (2) The MASP or SITP is greater than 15,000 psia at the seafloor 
for a well with a subsea wellhead or at the surface for a well with a 
surface wellhead; or
    (3) The flowing temperature is greater than 350 degrees Fahrenheit 
at the seafloor for a well with a subsea wellhead or at the surface for 
a well with a surface wellhead.

    Barrier categorization includes identifying barriers as one of the 
following two types of categories:
    Category 1 Barrier means any equipment, component, or assembly that 
functions as part of a primary barrier during any operational phase of 
its life cycle. The operational phases of the barrier equipment, 
component, or assembly are drilling, completion, workover, 
intervention, injection, production, or abandonment.
    Category 2 Barrier means any equipment, component, or assembly that 
normally functions as part of a secondary barrier during any 
operational phase of its life cycle, except when a primary barrier 
fails. The operational phases of the barrier equipment, component, or 
assembly are drilling, completion, workover, intervention, injection, 
production, or abandonment. BSEE may consider non-barrier structural 
components of a barrier system as a Category 2 Barrier if failure of 
this structural component could reasonably result in a Primary Barrier 
failure.

[[Page 71113]]

    Fit for Purpose means a determination made by an I3P at the 
conclusion of I3P review that the barrier equipment design has been 
verified and validated in conformance with recognized engineering 
standards and any additional project specification requirements; that 
the material selection, design verification analysis, design validation 
testing, and quality control are appropriate to justify the technical 
specifications; and that the technical specifications meet or exceed a 
project's site specific functional requirements.
    Fit for Service means a determination made by the operator that the 
material selection, design verification analysis, design validation 
testing, and quality control of the barrier equipment is appropriate to 
justify the technical specifications and that the technical 
specifications meet or exceed a project's site-specific functional 
requirements.
    New or unusual technology means equipment or procedures used for 
any drilling, completion, workover, intervention, injection, 
production, pipeline, platform, decommissioning, or abandonment 
operations that meet any of the following criteria:
    (1) Has not been approved for use or used extensively in a BSEE OCS 
Region;
    (2) Has not been approved for use or used extensively under the 
anticipated operating conditions;
    (3) Has operating characteristics that are outside the performance 
parameters established in this part;
    (4) Will operate in an HPHT environment as defined in Sec.  
250.105; or
    (5) Is part of a primary or secondary barrier system that uses 
materials, design analysis techniques, validation testing methods, or 
manufacturing processes not addressed in existing industry standards.
    Primary Barrier means the equipment, material, component, or 
assembly that is designated as the principal means of isolating the 
hydrocarbon pressure source from people and the environment.
    Secondary Barrier means the equipment, material, component, or 
assembly that is designated as the secondary means of isolating the 
hydrocarbon pressure source from people and the environment.
    Subsea tieback development technology means, but is not limited to, 
floating production systems, tension leg platforms, spars, Floating 
Production Storage and Offloading (FPSO) systems, guyed towers, 
compliant towers, subsea manifolds, subsea wells, hybrid wells, 
production risers, export risers, and other subsea completion or 
production components that rely on a remote site or host facility for 
utility and well control services.


Sec.  250.201  What plans and information must I submit before I 
conduct any activities on my lease or unit?

    (2) Pay a sum that the Regional Supervisor determines as adequate 
to compensate the Federal government for your failure to drill and 
produce any well.
    (b) Payment under paragraph (a)(2) of this section may constitute 
production in paying quantities for the purpose of extending the lease 
term.
    (c) You must complete and produce any penetrated hydrocarbon-
bearing zone that the Regional Supervisor determines is necessary to 
conform to sound conservation practices.


Sec.  250.203  Are there special requirements if my well affects an 
adjacent property?

    For wells that could intersect or drain an adjacent property, the 
Regional Supervisor may require special measures to protect the rights 
of the Federal government and objecting lessees or operators of 
adjacent leases or units.


Sec.  250.204  Requirements for high pressure high temperature (HPHT) 
barrier equipment.

    If you plan to install HPHT barrier equipment, you must submit 
information with your applicable Project Conceptual Plan, New or 
Unusual Technology Barrier Equipment Conceptual Plan, DWOP, and

Sec.  250.205  [Reserved]

Barrier Equipment and Systems


Sec.  250.206  What equipment does BSEE consider to be a barrier?

    A barrier or barrier system is any engineered equipment, material, 
component, or assembly that is installed to contain a hydrocarbon 
pressure source(s) to prevent harm to people or the environment. BSEE 
only recognizes barriers that are either permanently or temporarily 
installed, pressure controlling, and/or pressure containing. You must 
be able to activate pressure controlling barriers on demand (i.e., 
closed by an operator or automated safety system). You must function 
test and pressure test any pressure controlling barriers or barrier 
systems to defined acceptance criteria that can be repeated. You must 
pressure test any pressure containing barrier or barrier system to 
defined acceptance criteria that can be repeated.


Sec.  250.207  How must barrier systems be used?

    You must install and maintain a primary and a secondary barrier 
system (redundant barriers) to prevent a loss of containment during any 
operational phase of a well, flowline, pipeline, production, or riser 
system.

Activities and Post-Approval Requirements for the EP, DPP, DWOP, and 
DOCD


Sec.  250.208  How must I conduct activities under an approved EP, DPP, 
or DOCD?

    (a) Compliance. You must conduct all of your lease and unit 
activities according to your approved EP, DPP, or DOCD and any approval 
conditions. If you fail to comply with your approved EP, DPP, or DOCD:
    (1) You may be subject to BSEE enforcement action, including civil 
penalties; and
    (2) The lease(s) involved in your EP, DPP, or DOCD may be forfeited 
or cancelled under 43 U.S.C. 1334(c) or (d). If this happens, you may 
not be entitled to compensation under 30 CFR 550.185(b) and 30 CFR 
556.1102.
    (b) Emergencies. Nothing in this subpart or in your approved EP, 
DPP, or DOCD relieves you of or limits your responsibility to take 
appropriate measures to meet emergency situations. In an emergency 
situation, the Regional Environmental Officer may approve or require 
departures from your approved EP, DPP, or DOCD.


Sec.  250.209  What must I do to conduct activities under the approved 
EP, DPP, or DOCD?

    (a) Approvals and permits. Before you conduct activities under your 
approved EP, DPP, or DOCD you must obtain the following approvals and 
or permits, as applicable, from the District Manager or BSEE Regional 
Supervisor:
    (1) Approval of Applications for Permits to Drill (APDs) (see Sec.  
250.410);
    (2) Approval of production safety systems (see Sec.  250.800);
    (3) Approval of new platforms and other structures (or major 
modifications to platforms and other structures) (see Sec.  250.905);
    (4) Approval of applications to install lease term pipelines (see 
Sec.  250.1007); and
    (5) Other permits, as required by applicable law.
    (b) Conformance. The activities proposed in these applications and 
permits must conform to the activities described in detail in your 
approved EP, DPP, or DOCD.


Sec.  250.210  Do I have to conduct post-approval monitoring?

    The Regional Supervisor may direct you to conduct monitoring 
programs, including monitoring in accordance with the ESA and the MMPA, 
in association with your approved EP, DPP, DWOP, or DOCD. You must 
retain copies of all monitoring data obtained or derived from your 
monitoring programs and make them available to BSEE upon request. The 
Regional Supervisor may require you to:
    (a) Submit monitoring plans for approval before you begin work; and
    (b) Prepare and submit reports that summarize and analyze data and 
information obtained or derived from your monitoring programs. The 
Regional Supervisor will specify requirements for preparing and 
submitting these reports.


Sec.  250.211  What are my new or unusual technology failure reporting 
requirements?

    If you have an approved new or unusual technology and it 
experiences a failure (i.e., any condition that prevents the equipment 
from meeting its functional specification) during or post-installation, 
you must notify the applicable Regional Supervisor within 30 days of 
the failure. You must also provide a failure analysis report as soon as 
it is available following notification. The failure analysis report 
must include any results of and potential root cause(s) of the failure. 
You must also follow all applicable failure or incident reporting 
requirements associated with the failure (e.g., Sec. Sec.  250.188, 
250.730, and 250.803).


Sec.  Sec.  250.212-250.219  [Reserved]

Deepwater Operations Plan (DWOP) Process


Sec.  250.220  What is the DWOP process?

    (a) The DWOP process consists of providing sufficient information 
from a total system approach for BSEE to review:
    (1) A deepwater development project,
    (2) A subsea tieback development technology, or
    (3) Any other project or system that uses new or unusual technology 
during any phase of the following operations: drilling, completion, 
workover, intervention, injection, production,

[[Page 71115]]

pipeline, platform, decommissioning, or abandonment.
    (b) The DWOP process does not replace but complements other 
submittals required by the regulations, such as BOEM EPs, DPPs, and 
DOCDs, or BSEE applications and/or permits (e.g., APD, Application for 
Permit to Modify (APM), pipeline application, and platform 
application). BSEE will use the information in your DWOP process to 
determine whether the project will be developed in an acceptable 
manner, particularly with respect to operational safety and 
environmental protection involved with a deepwater development project, 
subsea tieback development technology, or new or unusual technology.
    (c) The DWOP process consists of two phases:
    (1) The Conceptual Plans. The Conceptual Plans outline certain 
equipment and process specifications, operational concepts, and basis 
of design that you plan to use for project development, and for 
applicable equipment design, installation, and operation. Sections 
250.227 through 250.229 prescribe what each of the Conceptual Plans 
must contain. Each Conceptual Plan may be submitted separately or 
combined as applicable; and
    (2) The DWOP. The DWOP identifies specific design, fabrication, 
installation and operational requirements for equipment, systems, and 
activities as applicable in Sec. Sec.  250.236 through 250.242.
    (d) You must submit to BSEE the applicable plan(s) covered under 
the DWOP process as appropriate (see Sec.  250.225 for Conceptual Plan 
requirements and Sec.  250.235 for DWOP requirements). Certain projects 
requiring New or Unusual Technology Conceptual Plans or New or Unusual 
Technology Barrier Equipment Conceptual Plans may not be required to 
have an associated Project Conceptual Plan or DWOP.


Sec.  250.221  When must I use the DWOP process?

    (a) You must use the DWOP process for any project that meets any of 
the following criteria:
    (1) Is planned in water depths greater than 1000 ft;
    (2) Will use subsea tieback development technology, regardless of 
water depth; or
    (3) Will use any new or unusual technology for any drilling, 
completion, workover, intervention, injection, production, pipeline, 
platform, decommissioning, or abandonment project.
    (b) If you are unsure if your project will use subsea tieback 
development technology or new or unusual technology, contact the 
Regional Supervisor for guidance.


Sec.  Sec.  250.222-250.224  [Reserved]

Conceptual Plans


Sec.  250.225  What are the types of Conceptual Plans that I must 
submit?

    There are three types of Conceptual Plans:
    (a) A Project Conceptual Plan is required for any project that is 
planned in water depths greater than 1000 feet, will use subsea tieback 
development technology, or will use new or unusual technology for 
completion, injection, production, pipeline, or platform operations;
    (b) A New or Unusual Technology Conceptual Plan is required for any 
project or system that involves equipment or procedures that are 
considered new or unusual technology (see Sec.  250.200 for the 
definition of new or unusual technology) for drilling, completion, 
workover, intervention, injection, production, pipeline, platform, 
decommissioning, or abandonment operations; and
    (c) A New or Unusual Technology Barrier Equipment Conceptual Plan 
is required for any project or system involving new or unusual 
technology that is also identified as a primary or secondary barrier 
(see Sec.  250.200 for the definition of primary and secondary 
barriers) for drilling, completion, workover, intervention, injection, 
production, pipeline, platform, decommissioning, or abandonment 
operations.


Sec.  250.226  When and how must I submit each applicable Conceptual 
Plan?

    You must submit each applicable Conceptual Plan to the Regional 
Supervisor after you have decided on the general concept(s) for a 
project or system, and before you finalize engineering design of the 
equipment, well, well safety control system, or subsea production 
systems. You must submit, for BSEE approval, each Conceptual Plan 
according to the following table:
