DEPARTMENT OF THE INTERIOR

Minerals Management Service

30 CFR Part 250

RIN 1010-AC03


Oil and Gas and Sulphur Operations in the Outer Continental Shelf

AGENCY: Minerals Management Service, Interior.

ACTION: Proposed rule.

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

SUMMARY: The Minerals Management Service (MMS) proposes to amend the 
documents incorporated by reference in regulations governing oil, gas, 
and sulphur operations in the Outer Continental Shelf (OCS). The 
organizations that publish the incorporated documents have revised some 
of the recommended practices and standards and have published new 
editions. The new editions will continue to ensure that lessees use the 
best available and safest technologies while operating in the OCS.

DATES: Comments must be received or postmarked on or before October 16, 
1995 to be considered in this rulemaking.

ADDRESSES: Written comments or recommendations must be mailed or hand-
carried to the Department of the Interior; Minerals Management Service; 
381 Elden Street; Mail Stop 4700; Herndon, Virginia 22070-4817; 
Attention: Chief, Engineering and Standards Branch.

FOR FURTHER INFORMATION CONTACT:
Andy Radford, Engineering and Standards Branch, telephone (703) 787-
1600.

SUPPLEMENTARY INFORMATION: MMS uses standards, specifications, and 
recommended practices developed by standard-setting organizations and 
the oil and gas industry as means of establishing requirements for 
activities in the OCS. This practice, known as incorporation by 
reference, allows MMS to incorporate the requirements of technical 
documents into the regulations without increasing the volume of the 
code of federal regulations. MMS currently incorporates by reference 68 
documents into the offshore operating regulations.
    The regulations found at 1 CFR part 51 govern how MMS and other 
Federal agencies incorporate various documents by reference. Agencies 
can only incorporate by reference through publication in the Federal 
Register. This generally includes standard rulemaking procedures, i.e., 
that the agency provide notice and opportunity for comment.
    Agencies must also gain approval by 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 MMS's 
regulations.
    The organizations that develop and publish the referenced technical 
documents revise and/or update most documents on a regular basis. Some 
organizations publish revisions to their documents every 6 months while 
others revise their documents every 2 to 5 years, if necessary. When 
these organizations publish revisions or new editions to referenced 
documents, MMS must determine if the changes warrant incorporating the 
new document in the regulations.
    Currently, over 50 documents incorporated by reference into MMS 
regulations are out of date. For most documents the changes between the 
old and new editions are minor. However, MMS must update these 
documents because the older editions may not be readily available to 
the affected parties. For instance, some American Petroleum Institute 
(API) documents currently referenced by MMS are out-of-print and no 
longer available. Other documents have undergone major revisions, and 
after reviewing these documents, MMS has determined that we must 
incorporate these documents to ensure the use of the best and safest 
technologies.
    In the future, MMS would like to keep the number of out of date 
documents incorporated by reference to a 

[[Page 42820]]
minimum. To accomplish this we are including language in the 
regulations to streamline the rulemaking process. Under our proposal, 
MMS would review new editions of documents we incorporate by reference 
as we do now. If MMS determines that the revisions are minor, or result 
in safety improvements, or represent new industry standard technology, 
and do not impose undue costs on the affected parties, MMS would update 
the documents incorporated by reference section of our regulations with 
a final rule published in the Federal Register. This means that the new 
document(s) would become effective without the public having prior 
opportunity to comment. This option is provided to agencies under 5 
U.S.C. 533(b) when the agency finds that notice and comment would be 
contrary to the public interest. MMS has found that most of the 
documents we propose for incorporation by reference come from 
organizations that have as members the parties affected by MMS 
regulations. By the time they release a new edition of a document, 
these parties have already commented on the new edition. It is 
redundant for MMS to issue the document for additional comments and 
unnecessarily delay the implementation of new ideas in the document. 
MMS will use the notice and comment process in any case where we have 
not previously incorporated the document by reference or when the new 
edition of a document already incorporated introduces controversial 
issues.

Document Incorporated by Reference in Subpart A

    API Recommended Practice (RP) 2D, Recommended Practice for 
Operation and Maintenance of Offshore Cranes, Third Edition, June 1, 
1995. It replaces the Second Edition of the same title. The new edition 
has a new format and is generally improved compared to the second 
edition. The third edition clearly defines who is qualified to operate 
and inspect offshore cranes. It also establishes minimum classroom 
training requirements for crane operators.

Documents Incorporated by Reference in Subpart D

    API RP 500, Recommended Practice for Classification of Locations 
for Electrical Installation at Petroleum Facilities, First Edition, 
June 1, 1991. This document replaces API RP 500B, Recommended Practice 
for Classification of Areas for Electrical Installations at Drilling 
Rigs and Production Facilities on Land and on Marine Fixed and Mobile 
Platforms, Second Edition, with Supplement. API RP 500 combined API RP 
500A, 500B, and 500C into a single document to provide guidelines for 
classifying locations at petroleum facilities for the selection and 
installation of electrical equipment. API RP 500 contains essentially 
the same information contained in API RP 500B.

Documents Incorporated by Reference in Subpart H

    1. American National Standards Institute/American Society of 
Mechanical Engineers (ANSI/ASME) Boiler and Pressure Vessel Code (1995) 
Section I, Power Boilers including Appendices; Section IV, Heating 
Boilers including Nonmandatory Appendices A, B, C, D, E, F, H, I, and J 
and the Guide to Manufacturers Data Report forms; and Section VIII, 
Pressure Vessels, Divisions 1 and 2 including Nonmandatory Appendices. 
These documents replace the 1983 Edition, with Summer and Winter 1983 
and 1984 and Summer 1985 Addenda. The MMS determined that the new code 
should be adopted into the regulations.
    2. API Spec 14A, Specification for Subsurface Safety Valve 
Equipment, Ninth Edition, December 1, 1994. This document replaces the 
seventh edition, with Supplement 1, of the same title. The new edition 
has a new format, but the major technical specifications essentially 
remain the same. The new edition also serves as the basis for 
International Standard Organization (ISO) document ISO 10432: 1993, 
titled Petroleum and natural gas industries-subsurface safety valve 
equipment.
    3. API RP 14B, Recommended Practice for Design, Installation, 
Repair and Operation of Subsurface Safety Valve Systems, Fourth 
Edition, July 1, 1994. This document replaces the Second Edition titled 
API RP 14B, Recommended Practice for Design, Installation, and 
Operation of Subsurface Safety Valve Systems. The new edition contains 
new classifications for subsurface safety valve equipment. Other 
revisions and additions clarify the document. The new edition also 
serves as the basis for ISO document ISO 10417: 1993, titled Petroleum 
and natural gas industries-Design, installation, repair and operations 
of subsurface safety valve systems.
    4. API Spec 14D, Specification for Wellhead Surface Safety Valves 
and Underwater Safety Valves for Offshore Service, Ninth Edition, June 
1, 1991. This document, with errata dated August 1, 1994, replaces the 
Seventh Edition of the same title. The new edition has a new format, 
but the major technical specifications essentially remain the same.
    5. API RP 14E, Recommended Practice for Design and Installation of 
Offshore Production Platform Piping Systems, Fifth Edition, October 1, 
1991. This document replaces the Fourth Edition of the same title. The 
Fifth Edition includes the following technical changes:

--Statement added to caution readers in the use of materials listed in 
National Association of Corrosion Engineers (NACE) MR-01-75, Material 
Requirements, Sulfide Stress Cracking Resistant Metallic Material for 
Oil Field Equipment, because the materials listed may be resistant to 
sulfide stress corrosion environments but may not be suitable for use 
in chloride stress cracking environments;
--Statement added concerning surge factors in large diameter flow lines 
between platforms;
--Equations revised in section 2.4 to incorporate Moody friction factor 
in lieu of Fanning friction factor because the Fanning factor was often 
misunderstood for the Moody friction factor causing numerous errors 
when determining pressure drop; and
--Section 3.2 revised to specify limitations of butterfly valves to use 
where tight shut off is not required.

    6. API RP 14F, Recommended Practice for Design and Installation of 
Electrical Systems for Offshore Production Platforms, Third Edition, 
September 1, 1991. This document replaces the Second Edition of the 
same title. The third edition includes the following technical changes:

--Section 2.5 revised to reflect that wiring for intrinsically safe 
systems needs only meet the requirements of article 504 of the National 
Electrical Code; therefore, eliminating the requirement for bulky, 
explosion-proof enclosures;
--Statement added in section 3.2 that a nationally recognized testing 
laboratory should verify ignition systems as suitable for hazardous 
locations;
--Statement added in section 4.4 to require an operator to equip oil 
treaters with a device to ground or deenergize the grid before the 
liquid level falls below the electrical equipment;
--Statement added in section 4.4 that an operator should route cable 
trays and cables so as to avoid mechanical damage; and
--Statement added in section 4.7 to address the use of flexible cords 
when initially installed.

    7. API RP 14G, Recommended Practice for Fire Prevention and Control 


[[Page 42821]]
on Open Type Offshore Production Platforms, Third Edition, December 1, 
1993. This document replaces the Second Edition of the same title. The 
new edition has requirements for bulk storage of flammable liquids 
where the old edition only had storage requirements for diesel fuel. 
The new edition has new requirements addressing fire detection and 
control.
    8. API RP 14H, Recommended Practice for Installation, Maintenance, 
and Repair of Surface Safety Valves and Underwater Safety Valves 
Offshore, Fourth Edition, July 1, 1994. This document replaces the 
Second Edition of the same title. The new edition recommends that the 
pressure test duration for surface safety valves and underwater safety 
valves should be a minimum of 5 minutes, whereas the current edition 
contained no minimum test period. The new edition also serves as the 
basis for ISO document ISO 10419:1993, titled Petroleum and natural gas 
industries-Drilling and production equipment-Installation, maintenance, 
and repair of surface safety valves and underwater safety valves 
offshore.
    Three other documents incorporated by reference in subpart H are 
also out-of-date, but MMS has chosen not to update them in this 
rulemaking. Following are the reasons we are not updating these 
documents at this time.
    1. ASME/ANSI Safety and Pollution Prevention Equipment (SPPE1-1988 
and SPPE-1a-1988, SPPE-1b-1989, SPPE-1c-1989, and SPPE-1d-1990 
(addenda), Quality Assurance and Certification of Safety and Pollution 
Prevention Equipment Used in Offshore Oil and Gas Operations. The MMS 
is currently evaluating its role in the SPPE program. Current plans 
call for MMS to organize focused workshops with all interested parties 
to clarify many of the issues involved in the SPPE program. Any updates 
to this document will be made following the workshops.
    2. API Spec Q1, Specification for Quality Programs, Third Edition. 
This document is also a part of the SPPE program. Any updates to this 
document will also be made following the workshops.
    3. API RP 14C, Recommended Practice for Analysis, Design, 
Installation and Testing of Basic Surface Safety Systems for Offshore 
Production Platforms, Fourth Edition, September 1, 1986. The new 
edition API issued contained many problems. Although API issued an 
errata sheet to correct these deficiencies, MMS feels that the 
deficiencies still remaining need to be corrected before we will 
incorporate the edition into our regulations.

unchanged.

    Author. The principal author for this proposed rule is Andy 
Radford, Engineering and Standards Branch, MMS.

Executive Order (E.O.) 12866

    This rule was reviewed under E.O. 12866. The rule was determined to 
not be a significant rule under the criteria of E.O. 12866 and, 
therefore, was not reviewed by the Office of Management and Budget 
(OMB).

Regulatory Flexibility Act

    The Department of the Interior (DOI) has also determined that this 
proposed rule will not have a significant economic effect on a 
substantial number of small entities because, in general, the entities 
that engage in activities offshore are not considered small due to the 
technical complexities and level of financial resources necessary to 
safely conduct such activities.

Paperwork Reduction Act

    This rule does not contain collections of information that require 
approval by OMB under (44 U.S.C. 3501 et seq.).
Takings Implication Assessment

    The DOI certifies that the proposed rule does not represent a 
governmental action capable of interference with constitutionally 
protected property rights. Thus, a Takings Implication Assessment need 
not be prepared pursuant to E.O. 12630, Government Action and 
Interference with Constitutionally Protected Property Rights.

E.O. 12778

    The DOI has certified to OMB that this proposed rule meets the 
applicable civil justice reform standards provided in Sections 2(a) and 
2(b)(2) of E.O. 12778.

National Environmental Policy Act

    The DOI has determined that this action does not constitute a major 
Federal action significantly affecting the quality of the human 
environment; therefore, preparation of an Environmental Impact 
Statement is not required.
