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: Final rule.
-----------------------------------------------------------------------
SUMMARY: The Minerals Management Service (MMS) amends 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 many
of their 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: EFFECTIVE DATE: December 26, 1996.
The incorporation by reference of certain publications listed in
this regulation is approved by the Director of the Federal Register on
December 26, 1996.
FOR FURTHER INFORMATION CONTACT:
Bill Hauser, 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 a 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 (CFR). 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.,
the agencies provide notice and opportunity for comment.
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 MMS's
regulations.
This rule updates more than 50 out-of-date documents incorporated
by reference into MMS regulations. 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 minimum. To accomplish this,
this rule includes language that streamlines the rulemaking process.
Under this rule, MMS will review new editions of documents we
incorporate by reference as we do now. If MMS determines that the
revisions are minor, result in safety improvements or represent new
industry standard technology, and do not impose undue costs on the
affected parties, MMS will update the documents incorporated by
reference section of our regulations with a final rule published in the
Federal Register. This means that the new edition of the document(s)
becomes effective without the public having prior opportunity to
comment. This option is provided to agencies under 5 U.S.C. 533(b) when
agencies find that the notice and comment would be impracticable,
unnecessary, or contrary to the public interest.
Narrative Response to Comments
MMS received comments on the notice of proposed rulemaking
(60FR42819) from oil and natural gas producers and trade organizations
representing oil and gas producers, pipeline companies, and drilling
contractors. A summary of their comments and MMS's response to each
comment follows below:
Comment: Three parties alerted MMS that some of the documents that
we had proposed to incorporate by reference have been superseded by
newer editions or documents with different titles.
MMS response: MMS reviewed the new documents, and if the changes
were
[[Page 60020]]
minor, noncontroversial, and did not impose any substantial new costs
to industry, we included the new documents in the final rule. Specific
documents we chose not to update include the following:
1. API Spec Q1--MMS will update the regulations to incorporate the
latest edition of this document in an upcoming rule.
2. API RP 2A-WSD--MMS, industry, and API are working on changes to
the 20th edition. When the changes are final, MMS will update the
regulations to incorporate the 20th edition of this document.
3. API RP 14C--MMS, industry, and API are working on changes to the
fifth edition. When the changes are final, MMS will update the
regulations to incorporate the fifth edition of this document.
Comment: Two parties asked MMS to consider including documents that
had not previously been incorporated by reference.
MMS response: MMS cannot include these documents until we review
them and then go through the notice and comment rulemaking procedure.
MMS will consider these and other documents in a future rulemaking.
Comment: One party asked MMS to include the words ``previously
incorporated'' in the introductory paragraph of Sec. 250.1. This
addition will make it clear that the streamlined process for updating
documents incorporated by reference applies only to previously
incorporated documents.
MMS response: MMS accepts this suggestion and has included the
words ``previously incorporated'' in this final rule.
Comment: One party asked that MMS not attach any other changes to
our regulations when we use the streamlined process to update documents
incorporated by reference.
MMS response: MMS does not intend to attach other changes to the
regulations when using the streamlined process to update documents
incorporated by reference.
Comment: Two parties criticized our streamlined method of updating
our documents incorporated by reference, and they suggested we use the
U.S. Coast Guard's (USCG) final rule of September 22, 1995 (60 FR
49222), as a model. Three parties supported our streamlining efforts.
MMS response: MMS believes that the method we proposed to
streamline the process of updating previously incorporated documents
will work better than the USCG's method suggested by the comments we
received. The USCG's method requires two notices (one initial notice
and one notice stating no comments disagreed with the proposal) in the
Federal Register, whereas our proposal only requires one. 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.
Anyone can send comments to MMS regarding our regulations at any time.
If an affected party has concerns with a new edition of any of the
documents incorporated by reference, that party should promptly voice
those concerns to MMS.
This final rule updates more than 50 documents that were out of
date, over two-thirds of our total documents. We should note that we
received only one negative comment concerning documents we proposed to
update. We did receive negative comments about other documents we have
concerns with, and thus declined to update. This rulemaking effort
indicates that our streamlined method of updating documents
incorporated by reference is sufficient.
To clarify when MMS will and will not use the streamlined
procedure, we have added language to the introductory paragraph of
Sec. 250.1, detailing the MMS will go through the traditional notice
and comment procedure to change the documents incorporated by reference
regulations whenever:
1. MMS proposes to include documents not previously incorporated by
reference.
2. The new edition of a document already incorporated by reference
introduces controversial issues, or imposes substantial new costs on
industry.
3. MMS proposes that a document cover parties not previously
affected by the document in question.
4. MMS believes it would be in the best interest of the public to
receive comments on a new edition.
Comment: One party commented that MMS adopts new standards without
regard to the feasibility or cost of implementing them on existing
facilities and equipment.
MMS response: MMS makes the determination about enforcing
requirements found in newer editions of documents incorporated by
reference on a case-by-case basis. We do not intend for parties to make
radical changes to their existing facilities or equipment because of
changes to the documents we incorporate. However, if the changes
reflected by the updated documents can be easily made, and result in
improvements in safety, then we would ask that parties conform to the
requirements found in the newer edition.
Comment: One party commented that MMS presumes that the industry
standards we cite are the relevant standards for all sectors of the
industry.
MMS response: While the documents we incorporate by reference are
intended for use by all parties operating in the OCS, parties have the
right to petition the Regional Supervisor for waivers to certain
requirements found in the documents. The Regional Supervisor makes a
decision on a case-by-case basis. If a certain sector of the industry
finds a document that is more suitable for their operations than the
document MMS incorporates, then they should submit the document to MMS
for consideration in future updates to our documents incorporated by
reference regulations.
Comment: One party asked MMS to clarify its position on the status
of documents referenced within the documents MMS incorporates by
reference. MMS refers to these documents as second-tier documents.
MMS response: When MMS incorporates a document by reference, we
intend for the users of that document to follow all parts of that
document unless otherwise noted. If users ignore the second-tier
document, then the document we incorporate loses its impact and its
usefulness to MMS and industry. The MMS position on this issue is that
second-tier documents apply unless otherwise noted, and parties should
follow them when conducting operations in the OCS.
Summary of Final Rule Revisions
Based on our review and analysis of the comments, the final rule
revises the regulations as follows:
1. The introductory paragraph in Sec. 250.1 indicates that MMS
will, in certain cases, update previously incorporated documents
without the public having prior opportunity to comment.
2. The latest editions of the following documents were not included
in the proposed rule but are included in the final rule. Organizations
either updated these documents between the time MMS drafted and the
Federal Register published the proposed rule or MMS was not aware that
the documents had been updated. After reviewing the documents, MMS has
determined that
[[Page 60021]]
the changes to these documents are minor, and we have included the
latest edition of the document in the final rule. A list of the
documents affected follows:
a. American Concrete Institute (ACI) Standard 318-89 was updated to
ACI Standard 318-95.
b. American National Standards Institute/American Society of
Mechanical Engineers (ANSI/ASME) B31.8-1989 was updated to ANSI/ASME
B31.8-1992.
c. Following are the API documents affected:
--API Spec 6A--This document includes a new section with specifications
for surface safety valves and underwater safety valves for offshore
service. The specifications are the same as those found in API Spec
14D. So, MMS has included API Spec 6A as an acceptable alternative to
API Spec 14D. MMS will continue to include API Spec 14D in the
regulations until API withdraws the document.
--API Spec 6AV1--This document contains the same information found in
various parts of API Spec 14D. MMS has included this document as an
acceptable alternative to parts of API Spec 14D.
--API Standard 2545--This document has been superseded by the Manual of
Petroleum Measurement Standards (MPMS), Chapter 3.1A and MPMS, Chapter
3.1B. Standard 2545 will remain in effect for pressurized vessels until
new MPMS, Chapter 3 documents are drafted. MMS will incorporate MPMS,
Chapter 3.1A and MPMS, Chapter 3.1B into the regulations since we have
reviewed these documents and determined that the differences between
them and Standard 2545 are minor. MMS will continue to incorporate
Standard 2545 as well.
--API Standard 2550--This document has been superseded by MPMS, Chapter
2.2A and MPMS, Chapter 2.2B. MMS will incorporate MPMS, Chapter 2.2A
and MPMS, Chapter 2.2B into the regulations since we have reviewed
these documents and determined that the differences between them and
Standard 2550 are minor. MMS will not continue to reference Standard
2550 since the API indicates that this document will be withdrawn soon.
--MPMS, Chapter 5.1 was updated to the Third Edition, September 1995.
--MPMS, Chapter 5.3 was updated to the Third Edition, September 1995.
--MPMS, Chapter 5.4 was updated to the Third Edition, September 1995.
--MPMS, Chapter 7.2 was updated to the Second Edition, March 1995.
--MPMS, Chapter 8.1 was updated to the Third Edition, November 1995.
--MPMS, Chapter 8.2 was updated to the Second Edition, November 1995.
--MPMS, Chapter 11.2.3 was updated to the Second Edition, November
1995.
In cases where API superseded other documents with new documents,
MMS had to make minor adjustments to the language in the regulations to
reflect the reference to a new document.
d. Following are the American Society for Testing and Materials
(ASTM) documents affected:
--ASTM Standard C33-90 was updated to ASTM Standard C33-93.
--ASTM Standard C94-91a was updated to ASTM Standard C94-95.
--ASTM Standard C150-89 was updated to ASTM Standard C150-95.
--ASTM Standard C595-90 was updated to ASTM Standard C595-95.
e. American Welding Society D1.1-92 was updated to D1.1-96.
f. National Association of Corrosion Engineers (NACE) Standard RP-
01-76 was updated to NACE Standard RP-0176-94.
3. API changed its stock numbering system in 1996. MMS changed the
stock numbers for API documents in the final rule.
Executive Order (E.O.) 12866
This rule was reviewed under E.O. 12866. The Department of the
Interior (DOI) has determined that the rule is not a significant rule
under the criteria of E.O. 12866 and, therefore, the rule was not
reviewed by the Office of Management and Budget (OMB).
Regulatory Flexibility Act
The DOI has determined that this final rule will not have a
significant economic effect on a substantial number of small entities.
This rule will not have a significant economic effect on any entity,
regardless of size. Any minor effects of this rulemaking will primarily
affect lessees and operators--entities that are not, by definition,
small due to the technical complexities and financial resources
necessary to conduct OCS activities. The indirect effects of this
rulemaking on small entities that provide support for offshore
activities were also determined to be small.
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 this final 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. 12988
The DOI has certified to OMB that this rule meets the applicable
civil justice reform standards provided in Sections 3(a) and 3(b)(2) of
E.O. 12988.
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.
Unfunded Mandate Reform Act of 1995
This rule does not contain any unfunded mandates to State, local,
or tribal governments or the private sector.
