30 CFR Part 250 

[Docket ID: BSEE–2022–0005 EEEE500000 

245E1700D2 ET1SF0000.EAQ000] 

RIN 1014–AA51 

Oil and Gas and Sulfur Operations in 

the Outer Continental Shelf— 

Documents Incorporated by Reference 

AGENCY: Bureau of Safety and 

Environmental Enforcement (BSEE), 

Interior. 

ACTION: Proposed rule. 

SUMMARY: BSEE proposes to incorporate 

documents by reference (Production 

Measurement Industry Standards and 

Safety Industry Standards, including 

one International Organization for 

Standardization/International 

Electrotechnical Commission standard) 

into the regulations governing oil, gas, 

and sulfur operations on the Outer 

Continental Shelf (OCS). Incorporation 

of these documents by reference would 

provide industry with up-to-date, 

minimum requirements for measuring 

oil and gas production volumes and 

enhancing safety. This would reduce 

uncertainty in the measurement of oil 

and gas production and update the 

minimum standards in the safety 

regulations. 

DATES: Submit comments by February 

28, 2024. BSEE is not obligated to 

consider or include in the 

Administrative Record for the final rule 

comments that we receive after the close 

of the comment period (see DATES) or 

comments delivered to an address other 

than those listed below (see ADDRESSES).

SUPPLEMENTARY INFORMATION: BSEE uses 

standards, specifications, recommended 

practices (RPs), and other Standard 

Development Organizations (SDO) 

documents as a means of establishing 

requirements for activities on the OCS. 

This practice, known as incorporation 

by reference, allows BSEE to incorporate 

the requirements of technical 

documents into the regulations at 30 

CFR 250.198 without increasing the 

volume of the Code of Federal 

Regulations (CFR). BSEE currently 

incorporates by reference the 

requirements found in 125 SDO 

documents into the offshore operating 

regulations. 

The regulations found at 1 CFR part 

51 govern how BSEE and other Federal 

agencies incorporate requirements 

found in various documents by 

reference. Agencies can only 

incorporate by reference through 

publication in the Federal Register. 

Agencies must also gain approval from 

the Director of the Federal Register for 

each publication incorporated by 

reference. Incorporation by reference of 

a document or publication is limited to 

the edition of the document or 

publication cited in the regulations. 

This means that newer editions, 

amendments, or revisions to documents 

already incorporated by reference in 

regulations are not part of BSEE 

regulations until they are specifically 

incorporated by reference. 

BSEE reviews and analyzes potential 

standards for incorporation into the 

regulations. In some cases, BSEE may 

find that a specific standard has 

particular utility. As a result, BSEE may 

incorporate that particular standard or 

only that portion of a relevant standard. 

Standards that are considered for 

incorporation are subject to a side-byside comparison of similar standards 

that are under consideration for 

proposed incorporation into BSEE’s 

regulations. Once the BSEE review is 

complete, we make a final 

determination regarding whether 

incorporating a standard will properly 

address our regulatory concerns and 

either accept or reject the standard 

proposed for incorporation. 

Availability of Incorporated Documents 

for Public Viewing 

When a copyrighted technical 

industry standard is incorporated by 

reference into our regulations, BSEE 

must observe and protect that copyright. 

BSEE provides members of the public 

with website addresses where these 

standards may be accessed for 

viewing—sometimes for free and 

sometimes for a fee. Each SDO is the 

copyright owner and decides whether to 

charge a fee. The American Petroleum 

Institute (API) provides free read-only 

online public access to about 160 key 

industry standards. The free read-only 

online standards represent almost onethird of all API standards and include 

all that are safety-related or have been

Federal Register / Vol. 88, No. 229 / Thursday, November 30, 2023 / Proposed Rules 83695 

incorporated into Federal regulations, 

including the standards in this proposed 

rule. The newly incorporated standards 

will be available for review online for 

free, and hardcopies and printable 

versions will continue to be available 

for purchase. 

We are also proposing to incorporate 

standards from other SDOs, including 

the American Gas Association (AGA), 

GPA Midstream Association (GPA), and 

American Society of Mechanical 

Engineers (ASME). Descriptions of the 

proposed standards below are adopted 

or paraphrased from the SDO 

publications. To purchase the 

copyrighted documents, the website

These documents, if incorporated in a 

final rule, would continue to be made 

available to the public for viewing upon 

request. Specific information on where 

these documents could be inspected or 

purchased would be set forth at 30 CFR 

250.198, Documents Incorporated by 

Reference. 

BSEE is proposing to incorporate the 

requirements found in API Manual of 

Petroleum Measurement Standards 

(MPMS), AGA documents, and GPA 

standards. These documents reflect the 

latest measurement standards, and their 

incorporation would provide industry 

with up-to-date requirements for 

measurement technology. BSEE is also 

proposing to incorporate other 

documents dealing with a variety of 

safety topics as described below. 

Ten standards proposed for 

incorporation by reference in this 

rulemaking (newly proposed standards) 

have not previously been incorporated 

by reference but have been used in 

practice by industry for at least a year 

and some for over a decade. The ten 

newly proposed standards are minimum 

safety standards. BSEE relies on 

standards as part of the bureau’s review 

of development and operations plans 

required for permit applications. 

Further, BSEE has inspection programs 

that monitor compliance with 

regulations, which includes the 

incorporated industry standards. 

The ten newly proposed standards 

comprise four integrity management 

standards, two offshore structure 

standards, two bolting/metallurgy 

standards, one crane related standard, 

and one well workover standard. The 

four integrity management standards 

pertain to recordkeeping and 

maintenance. The two structures 

standards are modifications of 

international standards that have been 

in use worldwide for decades. The two 

bolting/metallurgy standards are 

normative references in standards that 

are already incorporated by reference. 

The well workover standard is the 

second edition of a document that has 

already been in use by industry for 

approximately the past decade. The 

update to this standard was requested 

and reviewed by BSEE. 

The National Technology Transfer 

and Advancement Act (NTTAA) 

requires that ‘‘all Federal agencies . . . 

use technical standards that are 

developed or adopted by voluntary 

consensus standards bodies, using such 

technical standards as a means to carry 

out policy objectives or activities 

determined by the agencies and 

departments.’’ 104 Public Law 113, 

12(d)(1) (March 7, 1996). The relevant 

guidance in OMB Circular A–119 

instructs federal agencies to use 

appropriate industry consensus 

standards when developing regulations 

because consensus standards are written 

and updated routinely by industry 

experts. This standard-specific 

rulemaking is part of the Department’s 

effort to keep the standards in the 

regulations up to date. The American 

National Standards Institute (ANSI) 

generally requires that industry 

standards be updated at least every five 

years by the SDOs. The continual 

updating of standards results in 

standards that progressively evolve with 

the most recent safety criteria and 

industry norms, thereby evolving with 

new technology and addressing lessons 

learned. 

Measurement documents were chosen 

for incorporation into the regulations 

based on the latest technological 

advances introduced in these standards 

and highlighted in the synopsis below. 

BSEE, in cooperation with independent 

reviewers from industry and academia, 

reviews and comments on the contents 

of these documents. Additionally, since 

this is a proposed rulemaking, BSEE 

will consider any public comments that 

we receive and may rely on them in 

developing the final rule. 

BSEE continually participates in 

reviews, revisions, and updates of 

standards with SDOs and determines 

whether new editions should be 

incorporated into the Department’s 

regulations. This may be necessary 

because of changes in technology, 

environmental concerns, individual 

incidents, or incident trends. Also, 

BSEE may request an SDO to develop a 

new standard based on incident analysis 

or due to the introduction of new 

technologies, such as deep-water 

operations and floating production 

systems. 

BSEE has reviewed the requirements 

in the standards listed below and 

proposes to incorporate new standards 

into and revise some standards that 

have already been incorporated into the 

regulations at 30 CFR part 250 to ensure 

that industry uses the best available and 

most accurate measurement 

technologies. BSEE’s review indicates 

that the decision to use these standards 

will not impose additional costs on the 

offshore oil and gas industry, because 

industry currently uses these standards. 

Standards Proposed for Incorporation 

for the First Time or Proposed for 

Revisions and Summaries. 

What requirements must I follow for 

cranes and other material-handling 

equipment? (§ 250.108) 

BSEE proposes to add a reference to 

API Standard 2CCU (as incorporated by 

reference in § 250.198(e)(59)) to 

§ 250.108 new paragraph (g). 

Documents Incorporated by Reference. 

(§ 250.198) 

The standards listed below are 

presented in the order in which they 

would appear with proposed additions 

and revisions in § 250.198: 

Paragraph (b). 

BSEE does not propose any changes to 

subparagraph (b)(1). BSEE proposes to 

retain the AGA Reports Numbers 7 and 

10 as incorporated in existing § 250.198, 

add and update the other AGA Reports 

identified below in paragraph (b), and 

renumber the resulting subparagraphs as 

shown below and in the regulatory text: 

American Gas Association (AGA) 

Report No. 8, Part 1, Thermodynamic 

Properties of Natural Gas and Related 

Gases Detail and Gross Equations of 

State, Third Edition, April 2017. 

BSEE proposes to revise paragraph (b) 

of § 250.198 to incorporate by reference 


khammond on DSKJM1Z7X2PROD with PROPOSALS3
83696 Federal Register / Vol. 88, No. 229 / Thursday, November 30, 2023 / Proposed Rules 

for the first time AGA Report No. 8, Part 

1, into its regulations (proposed 

regulatory text: § 250.198(b)(2)). Part 1 

presents information for the 

computation of thermodynamic 

properties (e.g., compressibility factor, 

density, and speed of sound) of natural 

gas and related gases with the DETAIL 

and GROSS equations of state. 

Uncertainty estimations for different 

compositions, pressures, and 

temperatures are given in Part 1. The 

computations described in Part 1 are 

valid for single-phase gaseous states 

only. BSEE proposes to add a reference 

to this standard in § 250.1203(b). 

AGA Report No. 8, Part 2, 

Thermodynamic Properties of Natural 

Gas and Related Gases, GERG—2008 

Equation of State, First Edition, April 

2017. 

BSEE proposes to incorporate by 

reference for the first time AGA Report 

No. 8, Part 2 (proposed regulatory text: 

§ 250.198(b)(3)). Part 2 presents 

information for computation of 

thermodynamic properties, including 

compressibility factors, densities, and 

speeds of sound, of natural gas and 

related gases, for gaseous states, vaporliquid equilibrium states, and liquid 

states, based on the GERG–2008 

equation of state. It also improves upon 

the performance of the AGA 8 DETAIL 

equation for gas-phase properties, 

especially at high pressures and low 

temperatures. The ranges of 

temperature, pressure, and composition 

for which the GERG–2008 equation of 

state applies are much wider than the 

AGA 8 DETAIL equation. Uncertainty 

estimations for different compositions, 

pressures, and temperatures are given. 

With the availability of vapor-liquid 

equilibrium and liquid state 

calculations, Part 2 enables the 

calculation of dew points, bubble 

points, and the critical point. BSEE 

proposes to add a reference to this 

standard in § 250.1203(b) 

AGA Report No. 9—Measurement of 

Gas by Multipath Ultrasonic Meters, 

Fourth Edition, 2022. 

BSEE proposes to update the already 

incorporated reference of AGA Report 

No. 9 from the Second edition to the 

Fourth edition in its regulations 

(proposed regulatory text: 

§ 250.198(b)(4)). This standard describes 

the optimum conditions and best 

practices for multipath ultrasonic 

transit-time flow meters used for the 

measurement of natural gas. Multipath 

ultrasonic meters have at least two 

independent pairs of measuring 

transducers (acoustic paths). Typical 

applications include measuring the flow 

of gas through production facilities, 

transmission pipelines, storage 

facilities, distribution systems, and large 

end-use customer meter sets. BSEE 

currently requires multipath ultrasonic 

meters used for gas royalty 

measurement to contain at least three 

independent pairs of measuring 

transducers. BSEE incorporated the 

Second edition of this standard on 

March 29, 2012 (77 FR 18916). BSEE 

proposes to update the reference from 

the Second to the Fourth edition of this 

standard in § 250.1203(b)(2). The latest 

edition of AGA Report 9 allows the 

calibration of ultrasonic meters with 

laboratory piping in lieu of shipping the 

entire metering package to the 

calibration lab. 

AGA Report Number 10 will remain 

as previously incorporated by reference 

into the regulations, but will be 

renumbered to § 250.198(b)(5). 

AGA Report No. 11—Measurement of 

Natural Gas by Coriolis Meter, Second 

Edition, February 2013. 

BSEE proposes to incorporate by 

reference for the first time AGA Report 

No. 11, Second Edition, into its 

regulations (proposed regulatory text: 

§ 250.198(b)(6)). AGA Report No. 11 was 

developed for the specification, 

calibration, installation, operation, 

maintenance, and verification of 

Coriolis flow meters and is limited to 

the measurement of single-phase natural 

gas, consisting primarily of hydrocarbon 

gases mixed with other associated gases 

usually known as ‘‘diluents.’’ Although 

Coriolis meters are used to measure a 

broad range of compressible fluids, nonnatural gas applications are beyond the 

scope of this document. BSEE proposes 

to add a reference to this standard in 

§ 250.1203(b) as well. 

Paragraph (e)—American Petroleum 

Institute (API), API Recommended 

Practices, Specifications, Standards, 

Manual of Petroleum Measurement 

Standards (MPMS) chapters. 

BSEE proposes to reorganize 

paragraph (e) of § 250.198 to make it 

more user-friendly and easier to locate 

the API standards that BSEE 

incorporates by reference. BSEE 

proposes to replace the numbered list of 

the API standards that BSEE 

incorporates by reference with a table 

organized by category and standard 

number. Except as otherwise expressly 

discussed below, these changes are 

purely organizational and do not alter 

the substance of the paragraph. 

Separately, BSEE proposes to 

incorporate by reference additional API 

Standards in § 250.198 paragraph (e) 

and update others. BSEE also proposes 

to remove the references to API Bulletin 

2INT–MET, Interim Guidance on 

Hurricane Conditions in the Gulf of 

Mexico, May 2007, located in the 

existing regulations at § 250.198(e)(5), 

and API RP 86, Recommended Practice 

for Measurement of Multiphase Flow, 

September 2005, located in the existing 

regulations at § 250.198(e)(76). API 

Bulletin 2INT–MET was an interim 

document that provided best practices 

as of 2007 and is replaced in this rule 

by API RP 2MET—Derivation of 

Metocean Design and Operating 

Conditions, Second Edition, January 

2021. Similarly, API RP 86 was a 

document that provided best practices 

as of 2005 and is superseded by API 

MPMS, Chapter 20.3—Measurement of 

Multiphase Flow, First Edition January 

2013; reaffirmed October 2018, and 

supplemented in this rule by AGA 

Report No. 9—Measurement of Gas by 

Multipath Ultrasonic Meters, Fourth 

Edition, 2022. For explanations of the 

more up to date replacement standards, 

see the relevant locations in the sectionby-section discussions. 

API MPMS Chapter 1—Vocabulary, 

Second Edition, July 1994 is 

incorporated by reference in the current 

§ 250.198(e)(7) and will remain as 

previously incorporated by reference 

into the regulations, but will be 

renumbered in the proposed 

reorganized table as § 250.198(e)(1). 

API MPMS Chapter 2—Tank 

Calibration, Section 2A—Measurement 

and Calibration of Upright Cylindrical 

Tanks by the Manual Tank Strapping 

Method, First Edition, February 1995, 

reaffirmed August 2017 is incorporated

§ 250.198(e)(8) and will remain as 

previously incorporated by reference 

into the regulations, but will be 

renumbered in the proposed 

reorganized table as § 250.198(e)(2). 

BSEE is proposing to add an express 

reference to this standard in § 250.1202 

paragraphs (a) and (l) to clarify the 

longstanding use of this document 

already incorporated in the current 

regulations. 

API MPMS Chapter 2—Tank

current § 250.198(e)(9) and will remain 

as previously incorporated by reference 

into the regulations, but will be 

renumbered in the proposed 

reorganized table as § 250.198(e)(3). 

BSEE is proposing to add an express

and Liquid Petroleum Products— 

Calibration of Horizontal Cylindrical 

Tanks, Part 1: Manual Methods, First 

Edition, April 2004, Reaffirmed August 

2014, Errata November 2009. 

BSEE proposes to incorporate by 

reference for the first time API MPMS 

Chapter 2.2E, Part 1, into its regulations 

in § 250.198(e)(4). This standard is part 

of ISO 12917 and specifies manual 

methods for the calibration of nominally 

horizontal cylindrical tanks, installed at 

a fixed location. It is applicable to 

horizontal tanks up to 4 meters in 

diameter and 30 meters in length. The 

methods are applicable to insulated and 

non-insulated tanks, either when they 

are aboveground or underground. The 

methods are applicable to pressurized 

tanks, and to both knuckle-dish-end and 

flat-end cylindrical tanks, as well as 

elliptical and spherical head tanks. 

Information is also provided to address 

tanks that are larger than these 

dimensions. BSEE proposes to add a 

reference to this standard in 

§ 250.1202(a) as well. 

API MPMS Chapter 2.2F, Petroleum 

and Liquid Petroleum Products— 

Calibration of Horizontal Cylindrical 

Tanks, Part 2: Internal Electro-optical 

Distance-Ranging Method, First Edition, 

April 2004, reaffirmed September 2014. 

BSEE proposes to incorporate by 

reference for the first time API MPMS 

Chapter 2.2F, Part 2, into its regulations 

in § 250.198(e)(5). This standard is part 

of ISO 12917–2 and specifies a method 

for the calibration of horizontal 

cylindrical tanks having diameters 

greater than 2 meters by means of 

internal measurements using an electrooptical distance-ranging instrument, and 

for the subsequent compilation of tankcapacity tables. This method is known 

as the internal electro-optical distanceranging method. This part of ISO 

12917–2 is also applicable to tanks 

inclined by up to 10 percent from the 

horizontal provided a correction is 

applied for the measured tilt. BSEE 

proposes to add a reference to this 

standard in § 250.1202 as well. 

API MPMS Chapter 3.1A, Standard 

Practice for the Manual Gauging of 

Petroleum and Petroleum Products, 

Third Edition, August 2013, Errata 1, 

January 2021. 

BSEE proposes to update the 

incorporation by reference of this 

standard in the current § 250.198(e)(10) 

from the Second to the Third Edition, 

and to relocate it to § 250.198(e)(6). The 

title also changed from API MPMS 

Chapter 3, Section 1A to API MPMS 

Chapter 3.1A. The Third Edition added 

sections on gauging procedures, reading 

and recording gauges, operational 

precautions, and system integrity. This 

document describes the following 

procedures and influences for manual 

gauging: 

(1) The procedures for manually 

gauging the liquid level of petroleum 

and petroleum products in non-pressure 

fixed-roof, floating-roof tanks and 

marine tank vessels; 

(2) Procedures for manually gauging 

the level of free water that may be found 

with the petroleum or petroleum 

products; 

(3) Methods used to verify the length 

of gauge tapes under field conditions 

and the influence of bob weights and 

temperature on the gauge tape length; 

and 

(4) Influences that may affect the 

position of gauging reference point 

(either the datum plate or the reference 

gauge point). 

Throughout this standards document, 

the term petroleum is used to denote 

petroleum, petroleum products, or the 

liquids normally associated with the 

petroleum industry. This document is 

applicable for gauging quantities of 

liquids having Reid vapor pressures less 

than 103 kPa (15 psia). The Department 

incorporated the Second edition into its 

regulations on March 15, 2007 (72 FR 

12088). BSEE proposes to update the 

incorporation of the Third edition of 

this standard into § 250.1202(a).

of provers that do, and do not, 

accumulate a minimum of 10,000 whole 

meter pulses between detector switches, 

and provides design and installation 

details for the types of displacement 

provers that are currently in use. The 

provers discussed in this chapter are 

designed for proving measurement 

devices under dynamic operating 

conditions with single-phase liquid 

hydrocarbons. These provers consist of 

a pipe section through which a 

displacer travels and activates detection 

devices before stopping at the end of the 

run as the stream is diverted or 

bypassed. The Department incorporated 

the Third edition of this standard into 

its regulations on March 15, 2007 (72 FR 

12088). The Department here proposes

conditions by the use of an automatic 

method. Automatic temperature 

measurement is discussed for custody 

transfer and inventory control for both 

onshore and marine measurement 

applications. Temperatures of 

hydrocarbon liquids under static 

conditions can be determined by 

measuring the temperature of the liquid 

at specific locations. Examples of where 

static temperature determination is 

required include storage tanks, ships, 

and barges. The application of this 

standard is restricted to automatic 

methods for the determination of 

temperature using fixed automatic tank 

thermometer (ATT) systems for 

hydrocarbons having a Reid Vapor 

Pressure at or below 101.325 kPa

edition to the November 2022 Fourth 

edition in its regulations, and to relocate 

it to § 250.198(e)(32). The title of this 

standard changed from API MPMS 

Chapter 9, Section 2 to API MPMS 

Chapter 9.2. The Fourth Edition 

included distinguishing mandatory 

information and amended the 

referenced documents section. This test 

method covers the determination of the 

density or relative density of light 

hydrocarbons including liquefied 

petroleum gases (LPG) having Reid 

vapor pressures exceeding 101.325 kPa 

(14.696 psi). The prescribed apparatus 

should not be used for materials having 

vapor pressures higher than 1.4 MPa 

(200 psi) at the test temperature. This 

pressure limit is dictated by the type of 

equipment. Higher pressures can apply 

to other equipment designs. The initial 

pressure hydrometer readings obtained 

are uncorrected hydrometer readings 

and not density measurements. 

Readings are measured on a hydrometer 

at either the reference temperature or at 

another convenient temperature, and 

readings are corrected for the meniscus 

effect, the thermal glass expansion 

effect, alternate calibration temperature 

effects, and to the reference temperature 

by means of calculations and Adjunct to 

D1250 Guide for Petroleum 

Measurement Tables (API MPMS 

Chapter 11.1) or API MPMS Chapter 

11.2.4 (GPA TP–27), as applicable. The 

Department updated its incorporation of 

the Second edition of this standard into 

the regulations on March 15, 2007 (72 

FR 12088). BSEE proposes to update the 

reference of this standard in 

§ 250.1202(a). 

API MPMS Chapter 9.4—Continuous 

Density Measurement Under Dynamic 

(Flowing) Conditions, First Edition, 

January 2018. 

BSEE proposes to incorporate by 

reference for the first time API MPMS 

Chapter 9.4, into its regulations in 

§ 250.198(e)(33). This document covers 

the continuous on-line determination 

and application of flowing liquid 

densities for custody transfer. This 

document covers liquid and dense 

phase fluids, including natural gas 

liquids, refined products, chemicals, 

crude oil, and other liquid products 

commonly encountered in the 

petroleum industry. This document 

does not apply to the density 

measurement of natural gas, liquified 

natural gas, multiphase mixtures, semisolid liquids such as asphalt, and solids 

such as coke and slurries. This standard 

also provides criteria and procedures for 

designing, installing, operating, and 

proving continuous on-line density 

measurement systems for custody 

transfer. This standard also discusses 

the different levels and requirements of 

accuracy for various applications. BSEE 

proposes to add a reference to this 

standard in § 250.1202(a). 

API MPMS Chapter 10—Sediment 

and Water, Section 1—Standard Test 

Method for Sediment in Crude Oils and 

Fuel Oils by the Extraction Method, 

Third Edition, November 2007; 

reaffirmed October 2012 is incorporated 

by reference in the current 

§ 250.198(e)(34) and will remain in the 

proposed reorganized table as 

previously incorporated by reference in 

§ 250.198(e)(34). BSEE is proposing to 

add an express reference to this 

standard in § 250.1202(a) to clarify the 

longstanding use of this document 

already incorporated in the current 

regulations. 

API MPMS Chapter 10.2—Standard 

Test Method for Water in Crude Oil by 

Distillation, Fifth Edition, December 

2022. 

BSEE proposes to update the 

incorporation by reference of API 

MPMS Chapter 10.2, currently located 

at § 250.198(e)(35), from the 2007 

Second edition to the December 2022 

Fifth edition in its regulations in 

§ 250.198(e)(35). The title of this 

standard changed from API MPMS 

Chapter 10, Section 2 to API MPMS 

Chapter 10.2. The Fifth Edition 

accumulated references to ASTM 

documents and API documents 

associated terms and terminology along 

with related text. This test method 

covers the determination of water in 

crude oil by distillation. The values 

stated in the International System of 

Units (SI units) are to be regarded as 

standard. No other units of 

measurement are included in this 

standard. The Department updated its 

incorporation of the Second edition of 

this standard into the regulations on 

April 28, 2010 (75 FR 22219). BSEE 

proposes to update the reference of this 

standard into § 250.1202(a). 

API MPMS Chapter 10.3—Standard 

Test Method for Water and Sediment in 

Crude Oil by the Centrifuge Method 

(Laboratory Procedure), Fifth Edition, 

December 2022. 

BSEE proposes to update the 

incorporation by reference of API 

MPMS Chapter 10.3, currently located 

at § 250.198(e)(36), from the 2008 Third 

edition to the December 2022 Fifth 

edition in § 250.198(e)(36). The title of 

this standard changed from API MPMS 

Chapter 10, Section 3 to API MPMS 

Chapter 10.3. The Fifth Edition provides 

additional references to ASTM 

documents and API documents, 

mandatory and nonmandatory 

documents, test methods and associated 

terms and terminology, and additional 

information on constraints. This test 

method describes the laboratory 

determination of water and sediment in 

crude oils by means of the centrifuge 

procedure. This centrifuge method for 

determining water and sediment in 

crude oils is not entirely satisfactory. 

The amount of water detected is almost 

always lower than the actual water 

content. When a highly accurate value 

is required, the revised procedures for 

water by distillation, Test Method 

D4006 (API MPMS Chapter 10.2) (Note 

1), and sediment by extraction, Test 

Method D473 (API MPMS Chapter 10.1), 

shall be used. Test Method D4006 (API 

MPMS Chapter 10.2) has been 

determined to be the preferred and most 

accurate method for the determination 

of water. The values stated in SI units 

are to be regarded as standard. The 

Department updated its incorporation of 

the Third edition of this standard into 

the regulations on April 28, 2010 (75 FR 

22219). BSEE proposes to update the 

reference of this standard in 

§ 250.1202(a). 

API MPMS Chapter 10.4— 

Determination of Water and/or 

Sediment in Crude Oil by the Centrifuge 

Method (Field Procedure), Fifth Edition, 

August 2020. 

BSEE proposes to update the 

incorporation by reference of API 

MPMS Chapter 10.4, currently located 

at § 250.198(e)(37), from the 1999 Third 

edition to the 2020 Fifth edition in 

§ 250.198(e)(37). The title of this 

standard changed from API MPMS 

Chapter 10, Section 4 to API MPMS 

Chapter 10.4. The Fifth Edition 

amended text concerning procedures, 

calculations, and reporting related to 

centrifuge tube spin calculations, test 

procedures, and test reading 

requirements. This section describes the 

field centrifuge method for determining 

both sediment and water or sediment 

only in crude oil. This method may not 

always produce the most accurate 

results, but it is considered the most 

practical method for field determination 

of sediment and water. This method 

may also be used for field determination 

of sediment. When a higher degree of 

accuracy is required, the laboratory 

procedure described in API MPMS Ch.

by the Extraction Method (ASTM D473) 

should be used. The Department 

updated its incorporation of the Third 

edition of this standard into the 

regulations on March 15, 2007 (72 FR 

12088). BSEE proposes to update the 

reference of this standard in 

§ 250.1202(a). 

API MPMS Chapter 10.9—Standard 

Test Method for Water in Crude Oils by 

Coulometric Karl Fischer Titration, 

Third Edition, May 2013, reaffirmed 

June 2018. 

BSEE proposes to update the 

incorporation by reference of API 

MPMS Chapter 10.9 at § 250.198(e)(38) 

from the 2002 Second edition to the 

2013 Third edition, reaffirmed in 2018. 

The title of this standard changed from 

API MPMS Chapter 10, Section 9 to API 

MPMS Chapter 10.9. The Third Edition 

was updated with modern terminology 

to bring content into compliance with 

existing practices. This test method 

covers the determination of water in the 

range from 0.02 to 5.00 mass or volume 

% in crude oils. Mercaptan (RSH) and 

sulfide (S¥ or H2S) as sulfur are known 

to interfere with this test method, but at 

levels of less than 500 mg/g [ppm(m)], 

the interference from these compounds 

is insignificant. This test method can be 

used to determine water in the 0.005 to 

0.02 mass % range, but the effects of the 

mercaptan and sulfide interference at 

these levels has not been determined. 

For the range 0.005 to 0.02 mass %, 

there is no precision or bias statement. 

This test method is intended for use 

with standard commercially available 

coulometric Karl Fischer reagent. The 

values stated in SI units are to be 

regarded as standard. No other units of 

measurement are included in this 

standard. The Department updated its 

incorporation of the Second edition of 

this standard into the regulations on 

March 15, 2007 (72 FR 12088). BSEE 

proposes to update the reference of this 

standard in § 250.1202(a).

Crude Oils, Refined Products, and 

Lubricating Oils, 2004 Edition, May 

2004, Addendum 1 September 2007, 

Addendum 2 May 2019. 

BSEE proposes to update the 

incorporation by reference of API 

MPMS Chapter 11, Section 1, currently 

located at § 250.198(e)(41), in its 

regulations, and to relocate it to 

§ 250.198(e)(39). The 2007 Addendum 

replaced the term ‘‘Correction for 

Temperature and Pressure of a Liquid’’ 

for the term ‘‘Volume Correction 

Factor.’’ Where there is no pressure 

correction, then the Correction for 

Temperature (CTL) will replace the 

Volume Correction Factor. The 2019 

Addendum added 33 pages concerning 

compressibility, volume corrections, 

new terms, gauge pressure, and 

procedures. This standard provides the 

algorithm and implementation 

procedure for the correction of 

temperature and pressure effects on 

density and volume of liquid 

hydrocarbons which fall within the 

categories of crude oil, refined products, 

or lubricating oils. Natural gas liquids 

and liquid petroleum gases are excluded 

from consideration in this standard. The 

combination of density and volume 

correction factors for both temperature 

and pressure are collectively referred to 

in this standard as a Correction for 

Temperature and Pressure of a Liquid. 

The temperature portion of this 

correction is termed the Correction for 

the effect of Temperature on Liquid, 

also historically known as Volume 

Correction Factor. The pressure portion 

is termed the Correction for the effect of 

Pressure on Liquid. BSEE updated its 

incorporation of this standard into the 

regulations on March 29, 2012 (77 FR 

18916). BSEE proposes to update the 

reference of this standard in 

§ 250.1202(l).

API MPMS Chapter 12.2, Calculation 

of Petroleum Quantities Using Dynamic 

Measurement Methods and Volumetric 

Correction Factors, Second Edition, July 

2021. 

BSEE proposes to incorporate by 

reference API MPMS Chapter 12.2, 

Second Edition, July 2021 into its 

regulations in § 250.198(e)(43). API 

MPMS Chapter 12.2 supersedes three 

documents that have been withdrawn 

by API as outdated. Namely, API has 

withdrawn API MPMS Chapter 12.2.1, 

Second Edition 1995 (currently located 

at § 250.198(e)(43)), API MPMS Chapter 

12.2.2, Third Edition 2003 (currently 

located at § 250.198(e)(44)), and API 

MPMS Chapter 12.2.3, First Edition 

1998 (currently located at 

§ 250.198(e)(45)), and BSEE therefore 

proposes to remove those standards 

from the regulations in this rule. API 

MPMS Chapter 12.2 (2021) provides 

standardized calculation methods for 

the quantification of liquids, regardless 

of the point of origin or destination or 

the units of measure required by 

governmental customs or statute. The 

criteria contained in this document 

allow different entities using various 

computer languages on different 

computer hardware (or manual 

calculations) to arrive at output results 

within a defined tolerance within this 

document, using the same input data. 

The document specifies the equations 

for computing correction factors, rules 

for rounding, calculation sequence, and 

discrimination levels to be employed in 

the calculations. The intent of this 

document is to serve as a rigorous 

standard. This document also covers 

multiple calculations as required by 

dynamic, online, integrated, continuous 

flow measurement. BSEE proposes to 

add a reference to this standard in 

§ 250.1202(a).

BSEE proposes to incorporate by 

reference API MPMS Chapter 14.1, 

Eighth edition (September 2022) into its 

regulations in § 250.198(e)(45). This 

standard provides comprehensive 

guideline and procedures for properly 

extracting, collecting, conditioning, and 

handling a sample from a flowing 

natural gas stream at or above its dew 

point temperature and that represents 

the composition of the vapor-phase 

portion of the source fluid. This 

standard considers spot, composite, 

continuous, online, and mobile 

sampling systems and does not include 

sampling of liquid or multiphase 

streams. BSEE proposes to add a 

reference to this standard into 

§ 250.1203(b).

edition to the 2012 Fourth edition, with 

Errata through 2013 and reaffirmation in 

2017, in its regulations, and to relocate 

it to § 250.198(e)(46). The title of this 

standard changed from API MPMS 

Chapter 14, Section 3, Part 1 to API 

MPMS Chapter 14.3.1. The Fourth 

Edition made changes to equations to 

bring them into conformance with more

a single reference for engineering 

equations, uncertainty, estimations, 

construction, and installation 

requirements, and standardized 

implementation recommendations for 

the calculation of flow rate through 

concentric, square-edged, flange-tapped 

orifice meters. Both U.S. customary and 

SI units are included. The standard is 

organized into four parts. Parts 1, 2, and 

4 apply to the measurement of any 

Newtonian fluid in the petroleum and 

chemical industries. Part 3 focuses on 

the application of parts 1, 2, and 4 to the 

measurement of natural gas. This was 

previously titled Natural Gas Fluids 

Measurement, Section 3-Concentric, 

Square-Edged Orifice Meters, Part 1, 

now retitled as above to align with

normative references, specifications, 

considerations, and installation 

requirements. This publication outlines 

the specification and installation 

requirements for the measurement of 

single-phase, homogenous Newtonian 

fluids using concentric, square-edged, 

flange-tapped orifice meters. It provides 

specifications for the construction and 

installation of orifice plates, meter 

tubes, and associated fittings when

1.16.3.1, 1.16.3.2, and 1.16.3.3 of the 

First Edition, September 1993. 

BSEE proposes to update the 

incorporation by reference of API 

MPMS Chapter 20, Section 1, currently 

located at § 250.198(e)(53), to include 

the 2016 Reaffirmation and Addenda 

and Errata in its regulations, and to 

relocate it to § 250.198(e)(51), excluding 

sections 1.16.1, 1.16.3, 1.16.3.1, 

1.16.3.2, and 1.16.3.3 of the First 

Edition, September 1993. The excluded 

sections of the First Edition are 

superseded by API MPMS Chapter 20.3, 

First Edition January 2013, Reaffirmed 

October 2018, as further discussed 

below. The Addenda and Errata 

addressed measurement, calibration, 

equipment, and testing. This standard 

provides design and operating 

guidelines for liquid and gas allocation 

measurement systems. It includes 

recommendations for metering, static 

measurement, sampling, proving, 

calibrating, and calculating procedures. 

The Department updated its 

incorporation of the First edition of this 

standard into the regulations on March 

15, 2007 (72 FR 12088). BSEE proposes 

to update the reference of this standard 

in § 250.1202(a) and § 250.1203(b). 

API MPMS, Chapter 20.3— 

Measurement of Multiphase Flow, First 

Edition January 2013; reaffirmed 

October 2018. 

BSEE proposes to incorporate by 

reference for the first time API MPMS 

Chapter 20.3, First Edition January 

2013, Reaffirmed October 2018, into its 

regulations in § 250.198(e)(52). This 

document supersedes API 

Recommended Practice 86–2005, which 

is withdrawn. Further, this document 

supersedes API MPMS Chapter 20.1, 

First Edition 1993 sections 1.16.1, 

1.16.3, 1.16.3.1, 1.16.3.2, and 1.16.3.3 

and API Recommended Practice 85, 

First Edition 2003, portions of sections 

4, 6.1, 6.2, 6.3, 6.4, 6.5, 6.6, and 6.7. 

This publication addresses multiphase 

flow measurement in the production 

environment, upstream of the custody 

transfer (single-phase) measurement 

point, where allocation measurement for 

onshore, offshore, or subsea is applied. 

For other multiphase flow measurement 

applications such as reservoir 

management, well tests, and flow 

assurance, the standard can be used as 

a reference or guide. However, the focus 

of this standard is on those applications 

where the accuracy of multiphase flow 

measurement for allocation systems is 

required. This document refers to 

existing standards and RPs to 

supplement the guidance it provides in 

this subject area. The document 

addresses principles used in multiphase 

flow measurement, multiphase metering 

types and classifications, assessment of 

expected performance, and selecting 

and operating multiphase measurement 

systems. It addresses operational 

requirements or constraints, including 

expectations for flow meter acceptance, 

calibration criteria, flow loop and in situ 

verifications, and other guidance 

specific to different multiphase flow 

metering applications. The document 

does not address specific meter 

configurations. BSEE proposes to add a 

reference to this standard in 

§ 250.1203(b). 

API MPMS, Chapter 20.5— 

Recommended Practice for Application 

of Production Well Testing in 

Measurement and Allocation, First 

Edition, December 2017; reaffirmed 

March 2023. 

BSEE proposes to incorporate by 

reference for the first time API MPMS 

Chapter 20.5, First Edition, December 

2017, into its regulations in 

§ 250.198(e)(53). This document 

supersedes API MPMS Chapter 20.1, 

First Edition 1993, sections 1.7.2.2.2, 

1.11.1, 1.16.3.2, 1.16.3.3, 1.16.3.5.1, and 

Appendix J. This publication establishes 

a framework to conduct and apply 

production well testing for well rate 

determination in measurement and 

allocation. Production well testing 

addressed in this document refers to 

measurement of gas, oil, and water 

quantities from a single well during a 

specified length of time under 

controlled operational conditions. The 

intent of this document is to provide 

operators with a consistent and 

transparent approach for conducting, 

applying, and managing production 

well testing within an upstream 

measurement and allocation system. It 

is not intended to prescribe a particular 

production well test method, or 

particular application of production 

well test data use in allocation. This 

document provides recommendations 

and guidelines for the application of 

production well testing in production 

measurement and allocation. The 

recommendations and guidelines apply 

to conducting a production well test, 

calculating production well test 

volumes and rates, and the application 

of production well test data for use in 

measurement and allocation. This 

includes production well testing 

preparation, initiation, measurement, 

validation, and volume and rate 

calculations for separator, multiphase 

flow meter, and tank production well 

test systems. Additionally, this 

document addresses the proration of 

production well test results for use in 

allocation, the application of production 

well tests for validation and update of 

well flow models and virtual flow 

metering, and the adjustment of gas well 

continuous measurement results with 

production well test data. This 

document also provides 

recommendations and guidelines for the 

application of well flow modeling and 

virtual flow metering in production 

measurement and allocation. BSEE 

proposes to add a reference to this 

standard in § 250.1203(b).

API RP 2A–WSD, Recommended 

Practice for Planning, Designing, and 

Constructing Fixed Offshore Platforms— 

Working Stress Design, Twenty-second 

Edition, November 2014, Reaffirmation, 

September 2020. 

BSEE proposes to update the 

incorporation by reference of API 

Recommended Practice 2A–WSD, 

currently located at § 250.198(e)(57), 

from the 2000 Twenty-first edition to 

the 2014 Twenty-second edition in its 

regulations, and will remain as 

previously incorporated by reference in 

§ 250.198(e)(57). This RP is based on 

global industry best practices and serves 

as a guide for those who are concerned 

with the design and construction of new 

fixed offshore platforms and for the 

relocation of existing platforms used for 

the drilling, development, production, 

and storage of hydrocarbons in offshore 

areas. Specific guidance for hurricane 

conditions in the Gulf of Mexico and 

other U.S. offshore areas, previously 

provided in API RP 2A–WSD, 21st 

Edition, Section 2, is now provided in 

API RP 2MET. Specific guidance for 

earthquake loading in U.S. offshore 

areas, previously provided in the API 

RP 2A–WSD, 21st Edition, Section 2, is 

now provided in API 2EQ. Specific 

guidance for soil and foundation 

considerations in offshore areas, 

previously provided in API RP 2A– 

WSD, 21st Edition, Section 6, is now 

provided in API RP 2GEO. Specific 

guidance for the evaluation of structural 

damage, above and below water 

structural inspection, fitness-forpurpose assessment, risk reduction and 

mitigation planning, plus the process of 

decommissioning has been removed and 

is now provided in API RP 2SIM. 

Specific guidance for fire and blast 

loading, previously provided in the API 

RP 2A–WSD, 21st Edition, Section 18, is 

now provided in API 2FB. The 

Department updated its incorporation of 

the Twenty-first edition of this standard 

into the regulations on March 15, 2007 

(72 FR 12088). BSEE proposes to update 

the reference of this standard in the 

existing regulations at: §§ 250.901, 

250.908, 250.919, and 250.920. 

API Spec 2C, Specification for 

Offshore Pedestal Mounted Cranes, 

Eighth Edition, October 2020; API 

Monogram Program Effective Date: May 

1, 2021. 

BSEE proposes to update the 

incorporation by reference of API 

Specification 2C, currently located at 

§ 250.198(e)(81), from the 2004 Sixth 

edition to the 2020 Eighth edition in its 

regulations, and to relocate it to 

§ 250.198(e)(58). The Eighth Edition 

made changes concerning normative 

references, documentation, loads, 

structure, mechanical, and ratings. This 

standard provides requirements for 

design, construction, and testing of new 

offshore pedestal-mounted cranes. 

Offshore cranes are defined as pedestalmounted elevating and rotating lift 

devices for transfer of materials and 

personnel to or from marine vessels, 

barges, and structures or for transfer of 

materials to or from the sea or the 

seabed. Typical applications can 

include: offshore oil exploration and 

production applications which are 

typically mounted on a fixed structure, 

floating structure, or vessel used in 

drilling and production operations, 

shipboard applications which are 

mounted on surface-type vessels and are 

used to move cargo, containers, and 

other materials while the crane is within 

a harbor or sheltered area, and crane 

vessel applications which are typically 

mounted on ship-shaped vessels, semisubmersibles, barge, or self-elevating 

type marine vessels specialized in 

lifting heavy and/or unique loads for 

construction, pipe lay, renewable 

energy, salvage, and subsea applications 

in both harbor and offshore waters. The 

Department updated its incorporation of 

the Sixth edition of this standard into 

the regulations on April 28, 2010 (75 FR 

22219). BSEE proposes to update the 

reference of this standard in the existing 

regulations at § 250.108. 

API Standard 2CCU—Offshore Cargo 

Carrying Units; First Edition, August 

2017. 

BSEE proposes to incorporate by 

reference for the first time API Standard 

2CCU, first Edition, August 2017, into 

its regulations in § 250.198(e)(59). API 

Standard 2CCU defines the design, 

material, manufacture, inspection, 

repair, maintenance, and marking 

requirements for offshore cargo carrying 

units (CCU) and lifting sets, to include 

dry-goods boxes, baskets, and other 

skids designed to move equipment and 

goods offshore with maximum gross 

weight up to 70,000 kg (154,323 lb.). 

Annex A outlines the assessment 

criteria and parameters for in-service 

CCU equipment for continued fit-for 

purpose applications by users of CCU 

equipment in conjunction with 

equipment built to this standard. BSEE 

proposes to add an incorporation by 

reference of this standard in 

§ 250.108(g). 

API RP 2D, Operation and 

Maintenance of Offshore Cranes, 

Seventh Edition, December 2014; Errata 

August 2015, Addendum 1, October 

2020. 

BSEE proposes to update the 

incorporation of API Recommended 

Practice 2D, currently located at 

§ 250.198(e)(58), from the 2007 Sixth 

edition to the 2014 Seventh edition in 

its regulations, and to relocate it to 

§ 250.198(e)(60). The Seventh Edition 

added refueling, fire extinguishers, load 

testing, pull testing, derating, planning, 

risk assessment, lift plans, design, and 

preventative maintenance. This 

standard establishes general principles 

for the safe operation and maintenance 

of offshore pedestal-mounted revolving 

cranes on fixed or floating offshore 

platforms, offshore support vessels, 

jackup drilling rigs, semi-submersible 

drilling rigs and other types of mobile 

offshore drilling units, as a companion 

to API Spec 2C and API 2D–2. This 

standard also provides requirements 

and recommendations for lift planning, 

pre-use inspection, and testing of 

temporary cranes that are erected 

offshore. 

Typical applications can include: 

(1) Offshore oil exploration and 

production applications: These cranes 

are typically mounted on a fixed 

(bottom-supported) structure, floating 

platform structure, or vessel used in 

drilling and production operations, 

(2) Shipboard applications: These 

lifting devices are mounted on surfacetype vessels and are used to move cargo, 

containers, and other materials while 

the crane is within a harbor or sheltered 

area, and 

(3) Crane vessel applications. 

These cranes are typically mounted 

on ship-shaped vessels, 

semisubmersibles, barges, or selfelevating-type marine vessels 

specialized in lifting heavy and/or 

unique loads for construction, pipe lay, 

renewable energy, salvage, and subsea 

applications in both harbor and offshore 

waters. Equipment (e.g., davits, launch 

frames) used only for launching lifesaving appliances (lifeboats or life rafts) 

are not included in the scope of this 

standard. Lifting devices not covered by 

this standard would be operated, 

inspected, and maintained in

accordance with the manufacturer’s 

recommendations. The Department 

updated its incorporation of the Sixth 

edition of this standard into the 

regulations on April 28, 2010 (75 FR 

22219). BSEE proposes to update the 

reference of this standard in § 250.108. 

API RP 2FPS, Recommended Practice 

for Planning, Designing, and 

Constructing Floating Production 

Systems, Second Edition, October 2011; 

Reaffirmed September 2020. 

BSEE proposes to update the 

incorporation by reference of API 

Recommended Practice 2FPS, currently 

located at § 250.198(e)(59), from the 

2001 First edition to the 2011 Second 

edition in its regulations, and to relocate 

it to § 250.198(e)(61). The Second 

Edition made changes to bring the 

document into conformance with more 

recent practice, namely adding as 

normative references five API 

documents (API RP 2A–WSD, API 

Bulletin 2INT–MET, API RP 2SK, API 

RP 14J, 75L) and four ISO documents 

(13702, 19900–2002, 19901–1, 19902– 

2007). This document provides 

requirements and guidance for the 

structural design and/or assessment of 

floating offshore platforms used by the 

petroleum and natural gas industries to 

support the following functions: 

production, storage and/or offloading, 

and drilling. The Department updated 

its incorporation of the First edition of 

this standard into the regulations on 

April 28, 2010 (75 FR 22219). BSEE 

proposes to update the reference of this 

standard in the existing regulations at: 

§ 250.901. 

API RP 2FSIM—Floating Systems 

Integrity Management, First Edition, 

September 2019. 

BSEE proposes to incorporate by 

reference for the first time API RP 

2FSIM First Edition, September 2019 

into its regulations in § 250.198(e)(62). 

This RP provides guidance for floating 

system integrity management of floating 

production systems, which include 

tension leg platforms, used by the 

petroleum and natural gas industries to 

support drilling, production, storage, 

and/or offloading operations. Floating 

production systems described in this 

document are governed by local 

regulatory requirements and recognized 

classification society (RCS) rules, if 

classed. No specific regulatory 

compliance or RCS requirements are 

restated in the document. The 

requirements of this document do not 

apply to mobile offshore drilling units 

or to mobile offshore units used in 

support of construction operations. This 

document does not address dynamic 

positioning, moorings, or risers. BSEE 

proposes to add a reference to this 

standard in § 250.901. 

API RP 2GEO—Geotechnical and 

Foundation Design Considerations; First 

Edition, April 2011, Addendum 1, 

October 2014; Includes all amendments 

and changes through Reaffirmation 

Notice, January 2021. 

BSEE proposes to incorporate by 

reference for the first time API RP 

2GEO, First Edition October 2014, 

including all addenda and amendments 

through the January 2021 reaffirmation, 

into its regulations in § 250.198(e)(63). 

This document contains requirements 

and recommendations for those aspects 

of geoscience and foundation 

engineering that are applicable to a 

broad range of offshore structures, rather 

than to a particular structure type. Such 

aspects are site characterization, soil 

and rock characterization, design and 

installation of foundations supported by 

the seabed (shallow foundations), 

identification of hazards, design of pile 

foundations, and soil-structure 

interaction for risers, flowlines, and 

auxiliary subsea structures. Aspects of 

soil mechanics and foundation 

engineering are not addressed by the 

document. BSEE proposes to add a 

reference to this standard in § 250.901. 

API RP 2I, In-Service Inspection of 

Mooring Hardware for Floating 

Structures; Third Edition, April 2008 is 

incorporated by reference in the current 

§ 250.198(e)(60) and will remain as 

previously incorporated by reference 

into the regulations, but will be 

renumbered in the proposed 

reorganized table as§ 250.198(e)(64). 

API RP 2MET—Derivation of 

Metocean Design and Operating 

Conditions; Second Edition, January 

2021; ISO 19901–1:2015 (Modified) Part 

1. 

BSEE proposes to incorporate by 

reference for the first time API RP 

2MET, Second Edition, January 2021 

into its regulations in § 250.198(e)(65). 

This standard gives requirements for the 

determination and use of meteorological 

and oceanographic (metocean) 

conditions for the design, construction, 

and operation of offshore structures of 

all types used in the petroleum, natural 

gas, and renewable energy industries. 

The requirements are divided into two 

broad types: those that relate to the 

determination of environmental 

conditions in general, together with the 

metocean parameters that are required 

to adequately describe them; and those 

that relate to the characterization and 

use of metocean parameters for the 

design, the construction activities, or 

the operation of offshore structures. 

BSEE proposes to add a reference to this 

standard in § 250.901. 

API RP 2MIM—Mooring Integrity 

Management; First Edition, September 

2019. 

BSEE proposes to incorporate by 

reference for the first time API RP 

2MIM, First Edition, September 2019 

into its regulations in § 250.198(e)(66). 

This RP provides guidance for the 

integrity management of mooring 

systems connected to a permanent 

floating production system used for the 

drilling, development, production, and/ 

or storage of hydrocarbons in offshore 

areas. The scope of this RP extends from 

the anchor to the connection to the 

floating unit (e.g., chain stopper) and 

includes components critical to the 

mooring system (e.g., turret bearings, 

fairleads, chain stoppers, anchors, 

suction piles). BSEE proposes to add an 

incorporation by reference to this 

standard in § 250.901. 

ANSI/API RP 2N, Recommended 

Practice for Planning, Designing, and 

Constructing Structures and Pipelines

April 2015, ISO 19906:2010 (Modified) 

is incorporated by reference in the 

current § 250.198(e)(61) and will remain 

as previously incorporated by reference 

into the regulations, but will be 

renumbered in the proposed 

reorganized table as § 250.198(e)(67). 

API Standard 2RD, Dynamic Risers 

for Floating Production Systems, Second 

Edition, September 2013, Reaffirmed 

September 2020. 

BSEE proposes to update the 

incorporation by reference of API 

Standard 2RD, currently located at 

§ 250.198(e)(62), from the 1998 

Recommended Practice First Edition to 

the 2013 Standard Second Edition in its 

regulations, and to relocate it to 

§ 250.198(e)(68). The type and title of 

this document changed from API 

Recommended Practice 2RD to API 

Standard 2RD. The Standard Second 

Edition was updated to include high 

pressure high temperature 

considerations for hydrocarbon 

exploration and production in deep 

waters and made changes to testing to 

bring the document into conformance 

with more recent practice. This standard 

discusses riser systems that are part of 

a floating production system. Guidelines 

for design, construction, installation, 

operation, and maintenance of FPSs are 

in API RP 2FPS. A riser is a subsystem 

in a floating production system. The 

provisions of this standard do not apply 

to the riser systems of mobile offshore 

drilling units. There is significant 

interaction among the subsystems in a 

floating production system. Hull 

motions affect risers and mooring, and 

conversely, risers and mooring affect 

hull motions. Global behavior of the 


khammond on DSKJM1Z7X2PROD with PROPOSALS3
Federal Register / Vol. 88, No. 229 / Thursday, November 30, 2023 / Proposed Rules 83707 

system provides input to assessment of 

subsystems. Assessment of a subsystem 

provides feedback (loads) for assessment 

of the hull and other subsystems. 

Determination of the boundaries of a 

riser system and management of the 

interactions with other subsystems is 

the responsibility of the operator. A 

riser system is an assembly of 

components, including pipe and 

connectors. A riser system can include 

a riser tensioning system, buoyancy 

modules, etc. Pipe components can be 

steel, titanium, or unbonded flexible 

pipe. Design considerations for 

unbonded flexible pipe are included 

primarily by reference to API 17B and 

API Spec 17J. Design considerations for 

titanium alloy pipe are included 

primarily by reference to DNV–RP– 

F201. Steel and titanium pipe are 

referred to as rigid pipe and unbonded 

flexible pipe is referred to as flexible 

pipe. All or part of several existing 

codes, standards, specifications, and 

RPs are included by reference. Design 

loads and conditions are described in 

Section 4. Structural design criteria for 

rigid pipe are in Section 5. Structural 

capacity formulae for steel pipe are also 

in Section 5. Additional requirements 

for components, including pipe, are in 

Section 6. Material requirements are in 

Section 7. Fabrication and installation 

requirements are in Section 8. Integrity 

Management is addressed in Section 9. 

BSEE updated its incorporation of the 

First edition of this standard into the 

regulations on April 29, 2016 (81 FR 

25888). BSEE proposes to update the 

reference of this standard in §§ 250.733, 

250.800(c), 250.901, and 250.1002(b). 

API RP 2RIM—Integrity Management 

of Risers from Floating Production 

Systems; First Edition, September 2019. 

BSEE proposes to incorporate by 

reference for the first time API RP 2RIM, 

First Edition, September 2019 into its 

regulations in § 250.198(e)(69). This RP 

provides guidance for the integrity 

management of risers connected to a 

permanent floating production system 

used for the drilling, development, 

production, and storage of hydrocarbons 

in offshore areas. A riser is typically 

part of a larger subsea system extending 

from a wellhead, tree, manifold, 

template, or other structure on the 

seabed, to a boarding valve or pig trap 

on the host platform’s topsides. This 

document addresses the integrity 

management of the dynamic portion of 

the riser system. For the purposes of this 

document, a riser has a top boundary 

that is somewhere at or above the point 

where it transfers load to the platform 

structure, and it has a lower boundary 

where it transfers load into a 

foundation, which could be a wellhead, 

pipeline, or subsea structure. For a toptensioned riser, the top boundary would 

typically be the tensioner system hangoff point, and the bottom boundary 

would be the wellhead. For a steel 

catenary riser (SCR), the top boundary 

would typically be the stress joint or 

flexible joint. Unusual configurations, 

such as pull-tube steel catenary risers, 

merit special consideration. The top 

boundaries of a flexible or hybrid riser 

are typically a flanged connection to the 

riser end fitting at the top of an I-tube 

or J-tube, and a bend stiffener at the 

bottom of an I-tube or J-tube. The 

integrity management of the structural 

support for a riser on the host platform 

is in the scope of API RP 2FSIM, 

although some hybrid configurations, 

such as pull tubes, can require 

overlapping riser and structural 

integrity management. For risers 

structurally connected to the platform 

below the topsides, hull piping can be 

structurally clamped to the hull up to a 

boarding valve or pig launcher at the 

topsides. BSEE proposes to add an 

incorporation by reference to this 

standard in § 250.901. 

API RP 2SIM—Structural Integrity 

Management of Fixed Offshore 

Structures, First Edition, November 

2014; reaffirmed September 2020. 

BSEE proposes to incorporate by 

reference for the first time API RP 2SIM, 

First Edition, November 2014, 

reaffirmed September 2020, into its 

regulations in § 250.198(e)(70). This RP 

provides guidance for the structural 

integrity management of existing fixed 

offshore structures used for the drilling, 

development, production, and storage of 

hydrocarbons in offshore areas. 

However, the general principles of SIM 

apply to any structure. Specific 

guidance is provided for the evaluation 

of structural damage, above- and belowwater structural inspection, fitness-forpurpose assessment, risk reduction, 

mitigation planning, and the process of 

decommissioning. This RP incorporates 

and expands on the recommendations of 

Section 14, ‘‘Surveys’’ and Section 17, 

‘‘Assessment of Existing Platforms’’ as 

previously provided in API RP 2A– 

WSD, 21st Edition. See Annex A for 

additional information and guidelines 

on the provisions stated in the 

numbered sections of this document. 

The structural integrity management 

process provided in this RP is 

applicable to existing platforms 

installed at any location worldwide. 

However, the RP provides specific metocean criteria, which are only 

applicable for use in fitness-for-purpose 

assessments of platforms located in the 

U.S. Gulf of Mexico and off the U.S. 

West Coast. For guidelines, RPs, and 

other requirements relating to planning, 

designing, and constructing new fixed 

offshore platforms, including reuse and 

change-in-use of existing platforms, 

reference should be made to the latest 

edition of API RP 2A–WSD. For 

guidelines, RPs, and other requirements 

relating to planning, designing, and 

constructing new offshore floating 

production systems, including reuse 

and change-in-use of existing floating 

production systems, reference should be 

made to the latest edition of API RP 

2FPS. BSEE proposes to add an 

incorporation by reference of this 

standard in § 250.901(d).

made changes to include applications to 

floating production, storage, and 

offloading units, floating storage units, 

mobile offshore drilling units, spar 

platforms, catenary anchor leg mooring 

buoys, and mobile offshore units. 

Further, the Second Edition added 

provisions for rope design, 

specification, and testing. This 

document applies to synthetic fiber 

ropes used in the form of taut leg or 

catenary moorings for both permanent 

and temporary offshore installations. 

This document covers the following 

aspects of synthetic fiber ropes: design 

and analysis considerations of mooring 

system, design criteria for mooring 

components, rope design, rope 

specification and testing, rope 

manufacture and quality assurance, rope 

handling and installation, and in-service 

inspection and maintenance. 

Application of this document to other 

offshore mooring applications is at the 

discretion of the designer and operator. 

This document is not intended to cover 

other marine applications of synthetic 

fiber ropes such as tanker mooring at 

piers and harbors, towing hawsers, 

mooring hawsers at single-point

moorings, and tension leg platform 

tethers. Additionally, very little test data 

are available for large synthetic fiber 

ropes permanently deployed around 

fairleads and thus this document is 

limited to fiber ropes which span freely 

between end terminations. The 

Department updated its incorporation of 

the First edition of this standard into the 

regulations on April 28, 2010 (75 FR 

22219). BSEE proposes to update the 

reference of this standard in the existing 

regulations at: §§ 250.800(c) and 

250.901. 

API RP 2T, Recommended Practice for

regulations, and to relocate it to 

§ 250.198(e)(75). The Third Edition 

modified the Second Edition sufficient 

to change the document designation 

from Specification to Standard. Changes 

between editions included the terms 

and conditions, equipment 

specifications, validation requirements, 

seal tests, and procedural requirements. 

Further, the Standard establishes sandy 

service design validation for valves to 

meet Class II and Class III, but not for 

Class I safety valves or actuators. There 

are three service classes, Class I, Class 

II, and Class III, for API Specification 6A 

surface safety valve, underwater safety 

valve, or boarding shutdown valve. 

Class II is intended to validate the valve 

bore sealing mechanism if substances 

such as sand can be expected to cause 

safety or shutdown valve failure. Class 

III adds requirements and validation of 

the bonnet assembly inclusive of stem 

seals. BSEE updated its incorporation of 

the Second edition of this document 

into the regulations on September 28,

Spheres and Spheroids, First Edition, 

1966; reaffirmed, October 2007 because 

the document provided best practices as 

of 1965 which is now outdated and not 

applicable with the measurement and 

calibration requirements presently used. 

API Standard 2555, Method for Liquid 

Calibration of Tanks, First Edition, 

September 1966; reaffirmed May 2014. 

BSEE proposes to update the 

incorporation by reference of API 

Standard 2555, currently located at 

§ 250.198(e)(97), to include reference to 

a newer 2014 Reaffirmation in its 

regulations, and to relocate it to 

§ 250.198(e)(105). This standard 

describes the procedure for calibrating 

tanks, or portions of tanks, larger than 

a barrel or drum by introducing or 

withdrawing measured quantities of 

liquid. The Department updated its 

incorporation of the First edition of this 

standard into the regulations on April 

28, 2010 (75 FR 22219). This update 

reflects a more recent reaffirmation of 

the standard without substantive 

change. BSEE proposes to update the 

reference of this standard in § 250.1202. 

API RP 2556, Recommended Practice 

for Correcting Gauge Tables for 

Incrustation, Second Edition, August 

1993; reaffirmed November 2013. 

BSEE proposes to update the 

incorporation by reference of API 

Recommended Practice 2556, currently 

located at § 250.198(e)(80), to include a 

newer 2013 Reaffirmation in its 

regulations, and to relocate it to 

§ 250.198(e)(106). Incrustation is 

defined for the purpose of this RP as any 

material that adheres to the internal 

vertical sidewall surfaces of a tank when 

the tank is otherwise empty. 

Incrustation has the same effect on tank 

capacity as deadwood (anything that 

displaces liquid inside a tank) and 

should be treated as such as long as it 

remains in the tank. The problem of 

deducting the volume of liquid 

displaced by incrustation is complicated 

by two of incrustation’s basic and 

typical characteristics. First, 

incrustation is difficult to measure, and 

second, its thickness is usually variable. 

Some oils present no incrustation 

problem, but many others do, usually on 

a field-wide basis. The error in 

measurement from any one tank may be 

slight, but the accumulated error from 

an entire field or from any one tank over 

a period of time could be substantial. 

The error always has the effect of 

indicating too large a tank capacity; 

therefore, a receiving carrier cannot be 

expected to continually absorb the effect 

of these errors. The method selected to 

correct the error should depend upon 

the desired approach to accuracy of 

measurement. 

The tables given in this RP (see 

Section 4) show the percent of error of 

measurement caused by varying 

thicknesses of uniform incrustation in 

tanks of various sizes. These tables may 

be used as a guide by the tank owner 

and the carrier to negotiate an allowance 

for incrustation. If it is established that 

incrustation is causing a substantial loss 

to a carrier or to any other receiver using 

affected tank gauges as the basis for 

custody transfer measurement, it is the 

responsibility of the tank owner to 

provide a tank that will permit an 

accurate measurement or to agree to a 

reasonable adjustment. The Department 

updated its incorporation of the Second 

edition of this standard into the 

regulations on April 28, 2010 (75 FR 

22219). This update reflects a more 

recent reaffirmation of the standard 

without substantive change. BSEE 

proposes to update the reference of this 

standard in § 250.1202.

khammond on DSKJM1Z7X2PROD with PROPOSALS3
83712 Federal Register / Vol. 88, No. 229 / Thursday, November 30, 2023 / Proposed Rules 

BSEE proposes to update the 

incorporation by reference of ASME 

Boiler and Pressure Vessel Code, 

Section VIII, Division 1, at 

§ 250.198(f)(3) from the 2017 edition to 

the 2021 edition in its regulations. The 

2021 Edition made changes to bring the 

document into conformance with more 

recent practice, namely overpressure 

protections, permitted pressure relief 

devices and methods, design criteria, 

low temperature operation, and 

materials considerations. This code 

gives detailed requirements for the 

design, fabrication, testing, inspection, 

and certification of both fired and 

unfired pressure vessels. It specifically 

refers to those pressure vessels that 

operate at pressures, either internal or 

external, that exceed 15 psig. Section 

VIII is divided into 3 sections, each of 

which covers different vessel 

specifications. Division 1 addresses the 

requirements for design, fabrication, 

inspection, testing, and certification. 

Division 1 contains appendices, some 

mandatory and some non-mandatory, 

that detail supplementary design 

criteria, nondestructive examination 

techniques, and inspection acceptance 

standards for pressure vessels. Division 

1 also contains rules that apply to the 

use of the single ASME certification 

mark with the U, UM, and UV 

designators. BSEE updated the 

incorporation of the 2017 edition of this 

standard into its regulations on 

September 28, 2018 (83 FR 49216). 

BSEE proposes to update the reference 

of this standard in existing regulations 

at: §§ 250.851(a) and 250.1629(b). 

Paragraph (j)—International 

Organization for Standardization 

Standards. 

BSEE is only proposing changes to 

subparagraph (1) in paragraph (j) of 

§ 250.198. 

ISO/IEC (International 

Electrotechnical Commission) 17011, 

Conformity assessment—Requirements 

for accreditation bodies accrediting 

conformity assessment bodies, Second 

Edition 2017–11. 

BSEE proposes to update the 

incorporation by reference of ISO/IEC 

17011 at § 250.198(j)(1) from the 2004 

First edition to the 2017 Second edition 

in its regulations. The Second Edition 

made changes to bring the document 

into conformance with more recent 

practice. This document specifies 

requirements for the competence, 

consistent operation, and impartiality of 

accreditation bodies assessing and 

accrediting conformity assessment 

bodies. In the context of this document, 

activities covered by accreditation 

include, but are not limited to, testing, 

calibration, inspection, certification of 

management systems, persons, 

products, processes and services, 

provision of proficiency testing, 

production of reference materials, 

validation, and verification. BSEE 

incorporated the First Edition of this 

standard into its regulations on April 5, 

2013 (78 FR 20440). The second edition 

was revised and reorganized and an 

Annex A on knowledge and skills for 

performing accreditation activities was 

added. BSEE proposes to update the 

reference of this standard in existing 

regulations at: §§ 250.1900, 250.1903, 

250.1904, and 250.1922. 

Proposed paragraph (l)—Gas 

Processors Association (GPA) 

Standards. 

BSEE proposes to add a new 

paragraph (l) to § 250.198 that would 

include three GPA Standards. 

GPA Standard 2198–16—Selection, 

Preparation, Validation, Care and 

Storage of Natural Gas and Natural Gas 

Liquids Reference Standard Blends; 

Adopted as a Standard 1998; Revised 

August 2016; Reaffirmed 2017. 

(proposed § 250.198(l)(1)). 

BSEE proposes to incorporate by 

reference for the first time GPA 2198– 

16, as revised in 2016 and reaffirmed in 

2017, into its regulations (proposed 

regulatory text: § 250.198(l)(1)). This 

standard covers the recommended 

procedures for selecting the proper 

Natural Gas and Natural Gas Liquids 

Reference Standards, preparing the 

standards for use, verifying the accuracy 

of composition as reported by the 

manufacturer, and the proper care and 

storage of those standards to ensure 

their integrity and longevity during use. 

BSEE proposes to add a reference to this 

standard in § 250.1203(b). 

GPA Standard 2261–20—Analysis for 

Natural Gas and Similar Gaseous 

Mixtures by Gas Chromatography; 

Adopted as a standard 1964; Revised 

2020 (proposed § 250.198(l)(2)). 

BSEE proposes to incorporate by 

reference for the first time GPA 2261– 

20, as revised in 2020, into its 

regulations (proposed regulatory text: 

§ 250.198(l)(2)). This standard provides 

the gas processing industry with a 

method for determining the chemical 

composition of natural gas and similar 

gaseous mixtures using a Gas 

Chromatograph. The precision 

statements contained in this standard 

are based on the statistical analysis of 

round-robin laboratory data obtained by 

GPA Section B. This standard was 

developed by the cooperative efforts of 

many individuals from industry under 

the sponsorship of GPA Section B, 

Analysis and Test Methods. BSEE 

proposes to add a reference to this 

standard in § 250.1203(b). 

GPA Standard 2286–14—Method for 

the Extended Analysis of Natural Gas 

and Similar Gaseous Mixtures by 

Temperature Program Gas 

Chromatography; Adopted as a 

standard 1995; Revised 2014 (proposed 

§ 250.198(l)(3)). 

BSEE proposes to incorporate by 

reference for the first time GPA 2286– 

14, as revised in 2014, into its 

regulations (proposed regulatory text: 

§ 250.198(l)(3)). This standard covers 

the determination of the chemical 

composition of natural gas streams 

where precise physical property data of 

the hexanes and heavier fraction is 

required. This procedure is applicable 

for gaseous hydrocarbon mixes, which 

may contain nitrogen and carbon 

dioxide and/or hydrocarbon complexes 

C1 through C14 that fall within the 

ranges specified therein. This standard 

had previously seen only minor 

revisions since its adoption as a 

technical standard in 1986. The GPA 

revised portions of the standard that had 

become obsolete and that did not reflect 

current industry practices. In addition, 

the example calculations that use GPA 

2145 to reflect the 2009 revision of GPA 

2145 and all calculations related to 

those presented in GPA 2172 were 

removed and referenced to GPA 2172. 

The most significant changes to the 

standard involve updates to the method 

to maintain consistency with current 

technologies. BSEE proposes to add a 

reference to this standard in 

§ 250.1203(b).

these approaches are relevant, feasible, 

and consistent with regulatory 

objectives. E.O. 13563 further 

emphasizes 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. 

BSEE is incorporating by reference 

consensus standards developed by 

industry. Industry construes the 

consensus standards to be minimum 

requirements for safe operations. BSEE 

proposes to incorporate by reference 67 

consensus standards in its regulations. 

The consensus standards are widely 

practiced by industry operating on the 

OCS. The consensus standards proposed 

for incorporation by reference include 

ten standards that have not been 

previously incorporated in the BSEE 

regulations (30 CFR part 250) and the 

remainder that are updates of standards 

that have been previously incorporated. 

All the consensus standards proposed 

for incorporation by reference have been 

and continue to be widely used and 

practiced by the offshore industry. 

Thus, this rule aligns the BSEE 

regulations with the existing industry 

practice. Therefore, this rule maintains 

the burden that industry has set for 

itself. BSEE has developed this rule 

pursuant to the requirements of E.O. 

13563 to use industry standards to 

promote predictability, reduce 

uncertainty, and maintain the status quo 

with respect to burden. 

Regulatory Flexibility Act 

The Department of the Interior 

certifies that this proposed rule would 

not have a significant economic effect 

on a substantial number of small entities 

under the Regulatory Flexibility Act (5 

U.S.C. 601 et seq.). 

This proposed rule would affect 

lessees and operators of oil and gas 

leases on the OCS. This includes 

approximately 130 active Federal oil 

and gas lessees. Lessees that conduct 

business under this rule are coded 

under the Small Business 

Administration’s North American 

Industry Classification System (NAICS) 

codes 211111, Crude Petroleum and 

Natural Gas Extraction, and 213111, 

Drilling Oil and Gas Wells. For these 

NAICS code classifications, a small 

company is defined as one with fewer 

than 500 employees. BSEE estimates 

that approximately 70 percent of the 130 

lessees and operators that explore for 

and produce oil and gas on the OCS 

meet the definition of a small company. 

This rule proposes to incorporate 

consensus standards developed by 

accredited standard development 

organizations (SDOs) as minimum 

acceptable requirements. The accredited 

SDOs are required to develop standards 

with a process that is open, has 

balanced participation, provides due 

process, and has a specific appeal 

procedure—i.e., a multi-stakeholder 

process. The accredited SDOs require 

that all aspects of a consensus standard 

are fully negotiated including scope, 

definitions, and content. Any interested 

party can comment during the 

development process, and the 

comments must be fairly considered by 

the SDO and the commentor advised of 

the outcome and why—i.e., a 

consensus-based approach where 

comments from all stakeholders are 

considered. All the standards in this 

rule were developed by SDOs using this 

multi-stakeholder, fully negotiated, 

fairly considered, consensus-based 

approach. 

BSEE understands that such a 

consensus-based approach leads to high 

voluntary conformance rates by industry 

participants because all parties are 

encouraged and allowed to participate. 

Consensus-building is a fundamental 

requirement encompassed by each 

standard in this rule. Industry parties 

are required by SDO rules to resolve 

substantial objections early in the 

standards development stage. Thus, the 

regulated industry has had an 

opportunity to adopt and adhere to each 

consensus, industry standard prior to 

the publication of the standard and 

since. Furthermore, many of the 

industry standards being incorporated 

in this proposed rule are either updates 

to existing industry standards already 

incorporated by reference or have been 

adopted, adhered to, and published for 

numerous years. This consensus-based 

process has given industry participants 

sufficient time to integrate the standard 

into their operations. 

Since 2019, BSEE has made a 

concerted effort to work with industry 

and the public to understand and 

analyze the utility of consensus 

standards used by BSEE in its regulatory 

program. Over the past five years, three 

offshore standards workshops have been 

conducted by industry with BSEE 

participation, namely on January 29, 

2020, March 30, 2021, and May 11, 

2023. Each workshop included an 

analysis of the standards that BSEE uses 

or industry proposed BSEE use in its 

regulatory program. BSEE’s engagement 

with SDOs and industry stakeholders 

during the SDO workshops confirmed 

that industry’s voluntary conformance 

with consensus standards is high. The 

costs of incorporating such standards 

are, therefore, minimal since the high 

conformance rates mean the costs of 

adhering to the industry standard will 

be incurred regardless of this proposed 

rule and are appropriately considered to 

be part of the baseline. Although a few 

of the standards being incorporated by 

reference were adopted by SDOs within 

the last 2 years (e.g., API Specification 

6A, Specification for Wellhead and 

Christmas Tree Equipment and API 

Specification 6D, Specification for 

Pipeline Valves, both updated in 2023), 

voluntary conformance with these 

standards was already high at the time 

of adoption and is believed to have been 

increasing based on discussions during 

the SDO workshops. Therefore, most of 

the costs of adhering to these standards 

are also considered to be part of the 

baseline, as industry will incur them 

regardless of this proposed rule. Thus, 

incorporating the standards in this rule 

would not have a significant economic 

effect on a substantial number of small 

companies because any costs or burdens 

on any lessees or operators are a product 

of existing consensus minimum 

industry performance standards 

promulgated with broad stakeholder 

engagement and broadly adopted by 

industry regardless of incorporation into 

the regulations. 

Although the standards are available 

as read-only documents at BSEE offices 

and on the SDO websites, if any 

business wanted to own a copy, then the 

primary economic effect of this rule on 

small business would be the nominal 

cost associated with the purchase of the 

standards. 

Small Business Regulatory Enforcement 

Fairness Act 

The Small Business and Agriculture 

Regulatory Enforcement Ombudsman 

and 10 Regional Fairness Boards were 

established to receive comments from 

small businesses about Federal agency 

enforcement actions. The Ombudsman 

will annually evaluate the enforcement 

activities and rate each agency’s 

responsiveness to small business. If you 

wish to comment on the actions of 

BSEE, call 1–888–734–3247. You may 

comment to the Small Business 

Administration without fear of 

retaliation. Allegations of 

discrimination/retaliation filed with the 

Small Business Administration will be 

investigated for appropriate action.

Federal Register / Vol. 88, No. 229 / Thursday, November 30, 2023 / Proposed Rules 83715 

Congressional Review Act 

The proposed rule is not a major rule 

under the Congressional Review Act. 

This proposed rule: 

1. Would not have an annual effect on 

the economy of $100 million or more. 

The main purpose of this rule would be 

to add and update industry standards in 

the regulations to provide industry with 

up-to-date requirements in the use of 

new measurement and safety 

technology, consistent with existing 

industry practice. 

2. Would not cause a major increase 

in costs or prices for consumers, 

individual industries, Federal, State, or 

local government agencies, or 

geographic regions. The cost to comply 

with the rule would be consistent with 

the status quo, as it would only require 

compliance with industry standards to 

which affected entities already generally 

adhere. 

3. Would not have a significant 

adverse effect on competition, 

employment, investment, productivity, 

innovation, or ability of U.S.-based 

enterprises to compete with foreignbased enterprises. The requirements 

would apply to all entities operating on 

the OCS and reflect existing industry 

standards. 

Unfunded Mandates Reform Act of 1995 

This proposed rule would not impose 

an unfunded mandate on State, local, or 

tribal governments or the private sector 

of more than $100 million per year. The 

proposed rule would not have a 

significant or unique effect on State, 

local, or tribal governments or the 

private sector. A statement containing 

the information required by the 

Unfunded Mandates Reform Act (2 

U.S.C. 1501 et seq.) is not required. 

Takings Implication Assessment (E.O. 

12630) 

Under the criteria in E.O. 12630, this 

proposed rule does not have significant 

takings implications. The proposed 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 

proposed rule does not have federalism 

implications. This proposed rule would 

not substantially and directly affect the 

relationship between the Federal and 

State governments. To the extent that 

State and local governments have a role 

in OCS activities, this proposed rule 

would not affect that role. A Federalism 

Assessment is not required. 

Civil Justice Reform (E.O. 12988) 

This rule complies with the 

requirements of E.O. 12988. 

Specifically, this rule: 

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 

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 American Indian and 

Alaska Native Tribes through a 

commitment to consultation with the 

Tribes and recognition of their right to 

self-governance and Tribal sovereignty. 

We are also respectful of our 

responsibilities for consultation with 

Alaska Native Claims Settlement Act 

Corporations. We have evaluated this 

proposed rule under the Department’s 

consultation policy, under Departmental 

Manual part 512 chapters 4 and 5, and 

under the criteria in E.O. 13175 and 

determined that it would have no 

substantial direct effects on federally 

recognized Indian Tribes. 

Paperwork Reduction Act 

The proposed revisions do not 

contain any information collection and 

do not require a submission to the 

Office of Management and Budget for 

review and approval under the 

Paperwork Reduction Act of 1995 (44 

U.S.C. 3501 et seq.). 

National Environmental Policy Act of 

1969 (NEPA) 

This rule does not constitute a major 

Federal action significantly affecting the 

quality of the human environment. A 

detailed statement under the National 

Environmental Policy Act of 1969 is not 

required because the rule is covered by 

a categorical exclusion. This rule is 

excluded from the requirement to 

prepare a detailed statement because it 

falls within the Departmental 

categorical exclusion covering 

‘‘regulations . . . that are of an 

administrative, financial, legal, 

technical, or procedural nature; or 

whose environmental effects are too 

broad, speculative, or conjectural to 

lend themselves to meaningful analysis 

and will later be subject to the NEPA 

process, either collectively or case-bycase.’’ 43 CFR 46.210(i); see also 516 

Departmental Manual 15.4(C)(1) 

(covering ‘‘[i]ssuance and modification 

of regulations’’). We have also 

determined that the rule does not 

involve any of the extraordinary 

circumstances listed in 43 CFR 46.215 

that would require further analysis 

under the National Environmental 

Policy Act. 

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 § 515, 114 Stat. 2763, 2763A–153– 

154). 

Effects on the Energy Supply (E.O. 

13211) 

This rule is not a significant energy 

action under the definition in E.O. 

13211. A Statement of Energy Effects is 

not required. 

Clarity of This Regulation 

We are required by E.O. 12866, E.O. 

12988, and by the Presidential 

Memorandum of June 1, 1998, to write 

all rules in plain language. This means 

that each rule we publish must: 

(1) Be logically organized; 

(2) Use the active voice to address 

readers directly; 

(3) Use clear language rather than 

jargon; 

(4) Be divided into short sections and 

sentences; and 

(5) Use lists and tables wherever 

possible. 

If you feel that we have not met these 

requirements, send us comments by one 

of the methods listed in the ADDRESSES

section. To better help us revise the 

rule, your comments should be as 

specific as possible. For example, you 

should tell us the numbers of the 

sections or paragraphs that you find 

unclear, which sections or sentences are 

too long, the sections where you feel 

lists or tables would be useful, etc.
