Airworthiness Directives; General Electric Company GE90-110B1,
GE90-113B, and GE90-115B Series Turbofan Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
General Electric Company (GE) GE90-110B1, GE90-113B, and GE90-115B
series turbofan engines with stage 6 low-pressure turbine (LPT) blades,
part number (P/N) 1765M37P03 or P/N

1765M37P04, installed. This AD requires initial and repetitive
inspections for shroud interlock wear of the stage 6 LPT blades. This
AD also requires replacing those blades with stage 6 LPT blades
eligible for installation at the next engine shop visit as terminating
action to the repetitive blade inspections. This AD results from eight
reports of GE90-115B stage 6 LPT single-blade separation events. We are
issuing this AD to prevent failure of stage 6 LPT blades, which could
result in uncontained engine failure and damage to the airplane.

DATES: This AD becomes effective January 19, 2010. The Director of the
Federal Register approved the incorporation by reference of certain
publications listed in the regulations as of January 19, 2010.

ADDRESSES: You can get the service information identified in this AD
from General Electric Company via GE-Aviation, Attn: Distributions, 111
Merchant St., Room 230, Cincinnati, Ohio 45246; telephone (513) 552-
3272; fax<PHONE_NUMBER>.

SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39
with a proposed AD. The proposed AD applies to GE GE90-110B1, GE90-
113B, and GE90-115B series turbofan engines with stage 6 LPT blades, P/
N 1765M37P03 or P/N 1765M37P04, installed. We published the proposed AD
in the Federal Register on June 24, 2009 (74 FR 30020). That action
proposed to require initial and repetitive inspections for shroud
interlock wear of the stage 6 LPT blades. That action also proposed to
require replacing those blades with stage 6 LPT blades eligible for
installation at the next engine shop visit as terminating action to the
repetitive blade inspections.

Examining the AD Docket

    You may examine the AD docket on the Internet at http://
www.regulations.gov; or in person at the Docket Operations office
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The AD docket contains this AD, the regulatory evaluation,
any comments received, and other information. The street address for
the Docket Operations office (telephone<PHONE_NUMBER>) is provided in
the ADDRESSES section. Comments will be available in the AD docket
shortly after receipt.

Comments

    We provided the public the opportunity to participate in the
development of this AD. We have considered the comments received.

Request To Include Service Bulletin (SB) Revision 3

    One commenter, All Nippon Airways, requests that we include GE SB
No. GE90-100 SB 72-0260, Revision 3, dated July 17, 2008, in Previous
Credit paragraph (i).
    We do not agree. That SB does not specifically call out the need to
inspect engines with replacement, original configuration, stage 6 LPT
blades. We did not change the AD.

Request To Correct SB Paragraph References

    All Nippon Airways and Japan Airlines requests that in paragraph
(f), we correct the reference of what paragraphs to use in the SB, from
``3.A through 3.A.(3)(g)(12)'', to ``3.A through 3.A.(2)(g)(12)''.
    We agree the reference needs correcting. We made the correction,
but listed the latest revision of the SB, which is GE SB No. GE90-100
SB 72-0260, Revision 7, dated June 2, 2009. We also added SB No. GE90-
100 SB 72-0260, Revision 6, dated May 1, 2009, to the Previous Credit
paragraph.

Requests To Change the Unsafe Condition Paragraph (d)

    GE Aviation requests that we change the Unsafe Condition paragraph
(d) to state that, in each case, the engine continued to produce
commanded thrust.
    We do not agree. Although the statement is true, adding it would
lessen the impact of, and detract from, the existing unsafe condition
statement. We did not change the AD.
    Boeing requests that we change the Unsafe Condition paragraph (d)
to also state that there is a remote possibility of the unsafe
condition event occurring on both engines on a given flight.
    We do not agree. We considered the possibility of a dual-engine
failure event during our safety analysis and when determining the
appropriate compliance actions for this AD. We did not change the AD.

Request To Reference the Latest GE SB Revision

    GE Aviation, Japan Airlines, and Eva Air request that we reference
using latest GE SB in the AD, which is SB No. GE90-100 SB 72-0260,
Revision 7, dated June 2, 2009.
    We agree and have referenced the use of Revision 7 in the AD.

Request To Reference the Use of Later-FAA-Approved SB Revisions

    One commenter, V Australia, requests that we state to use ``or
later-FAA-approved revision of the SB'' in the AD. The commenter states
that Revision 7 has been issued since the proposed AD was issued, and
it is likely that GE will issue more revisions.
    We do not agree. Rulemaking requirements do not permit advance
approval of unknown future revisions to service bulletins. We did not
change the AD.

Request To Add SB Revision 6 to Previous Credit Paragraph (i)

    GE Aviation and Japan Airlines request that we add GE SB No. GE90-
100 SB 72-0260, Revision 6, dated May 1, 2009, to the list of SB
revisions in the Previous Credit paragraph (i).
    We agree and added SB Revision 6 to that paragraph.

Request for Change in Definition Paragraph (j)

    Japan Airlines requests that we change the Definition paragraph (j)
to exclude the induction of engines into the shop for maintenance
action that can be performed at line maintenance, but which is
performed in the shop for operator convenience. The commenter states
that making this change will help eliminate an unnecessary burden to
the operators.
    We do not agree. The existing engine shop visit definition is
intended to lead operators to perform the terminating action as soon as
possible. Doing this will reduce the reliance upon repetitive
inspections and continued risk of blade failure. We did not change the
AD.

Conclusion

    We have carefully reviewed the available data, including the
comments received, and determined that air safety and the public
interest require adopting the AD with the changes described previously.
We have determined that these changes will neither increase the
economic burden on any operator nor increase the scope of the AD.

Costs of Compliance

    We estimate that this AD will affect four GE GE90-110B1, GE90-113B,
and

GE90-115B series engines installed on airplanes of U.S. registry. We
also estimate that it will take about 18 work-hours per engine to
perform one inspection of the stage 6 LPT blades, and that the average
labor rate is $80 per work-hour. Replacement stage 6 LPT blades will
cost $258,280 per engine. We estimate that no additional labor costs
will be incurred to perform the required blade replacements, because
the replacements will be done during a scheduled engine shop visit.
Based on these figures, we estimate the total cost of the AD for one
inspection to U.S. operators to be $1,038,880.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, Section 106, describes the
authority of the FAA Administrator. Subtitle VII, Aviation Programs,
describes in more detail the scope of the Agency's authority.
    We are issuing this rulemaking under the authority described in
Subtitle VII, Part A, Subpart III, Section 44701, ``General
requirements.'' Under that section, Congress charges the FAA with
promoting safe flight of civil aircraft in air commerce by prescribing
regulations for practices, methods, and procedures the Administrator
finds necessary for safety in air commerce. This regulation is within
the scope of that authority because it addresses an unsafe condition
that is likely to exist or develop on products identified in this
rulemaking action.

Regulatory Findings

    We have determined that this AD will not have federalism
implications under Executive Order 13132. This AD will not have a
substantial direct effect on the States, on the relationship between
the national government and the States, or on the distribution of power
and responsibilities among the various levels of government.
    For the reasons discussed above, I certify that this AD:
    (1) Is not a ``significant regulatory action'' under Executive
Order 12866;
    (2) Is not a ``significant rule'' under DOT Regulatory Policies and
Procedures (44 FR 11034, February 26, 1979); and
    (3) Will not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
    We prepared a summary of the costs to comply with this AD and
placed it in the AD Docket. You may get a copy of this summary at the
address listed under ADDRESSES.

AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).

ACTION: Final rule; request for comments.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for the
products listed above. This AD results from mandatory continuing
airworthiness information (MCAI) issued by an aviation authority of
another country to identify and correct an unsafe condition on an
aviation product. The MCAI describes the unsafe condition as affecting
only RB211 Trent 500 series turbofan engines that have not incorporated
Rolls-Royce plc (RR) Service Bulletin (SB) No. RB.211-72-D733, dated
August 21, 2002, or Revision 1 of that SB, dated March 6, 2008, as
follows:

    The intermediate-pressure (IP) turbine blade shrouds of the
RB211 Trent 500 series engines feature closure welds (dust caps).
Development engine testing has revealed the potential for dust caps
to crack, lift and release. The latter may potentially allow hot
annulus gas to be ingested down the core passages of IP turbine
blades. Radial inflow of annulus gas into the IP disc rim region
could cause local heating of the disc firtree, resulting in creep of
the disc material. Failure of the disc rim in creep could
simultaneously release two blades and a disc post. Failure to this
extent could be beyond the containment capabilities of the casing.
Consequently, release of the dust caps would constitute a
potentially unsafe condition.

This AD requires actions that are intended to address the unsafe
condition described in the MCAI, which could result in uncontained
release of IP turbine blades and disc posts, resulting in damage to the
airplane.

DATES: This AD becomes effective December 1, 2008.
    We must receive comments on this AD by December 15, 2008.
    The Director of the Federal Register approved the incorporation by
reference of Rolls-Royce plc Alert Service Bulletin (ASB) No. RB.211-
72-AF994, Revision 1, dated September 1, 2008 and SB No. RB.211-72-

SUPPLEMENTARY INFORMATION:

Discussion

    EASA, which is the Technical Agent for the Member States of the
European Community, has issued EASA AD 2008-0109 R1, dated June 17,
2008, to correct an unsafe condition for the specified products. The
EASA AD states that for RB211 Trent 500 series turbofan engines that
have not incorporated RR SB No. RB.211-72-D733, dated August 21, 2002,
or Revision 1 of that SB, dated March 6, 2008, the unsafe condition is
as follows:

    The intermediate-pressure (IP) turbine blade shrouds of the
RB211 Trent 500 series engines feature closure welds (dust caps).
Development engine testing has revealed the potential for dust caps
to crack, lift and release. The latter may potentially allow hot
annulus gas to be ingested down the core passages of IP turbine
blades. Radial inflow of annulus gas into the IP disc rim region
could cause local heating of the disc firtree, resulting in creep of
the disc material. Failure of the disc rim in creep could
simultaneously release two blades and a disc post. Failure to this
extent could be beyond the containment capabilities of the casing.
Consequently, release of the dust caps would constitute a
potentially unsafe condition.

You may obtain further information by examining the MCAI in the AD
docket.

Relevant Service Information

    Rolls-Royce plc has issued ASB No. RB.211-72-AF994, Revision 1,
dated September 1, 2008 and SB No. RB.211-72-D733, Revision 1, dated
March 6, 2008. The actions described in this service information are
intended to correct the unsafe condition identified in the MCAI.

FAA's Determination and Requirements of This AD

    Although no airplanes registered in the United States use these
engines, the possibility exists that the engines could be used on
airplanes registered in the United States in the future. The unsafe
condition described previously is likely to exist or develop on other
engines of

the same type design. We are issuing this AD to prevent release of IP
turbine blades and disc posts, resulting in damage to the airplane.
This AD requires:
     Initial and repetitive borescope inspections for missing
or lifting IP turbine blade outer shroud dust caps; and
     Installation of core restrictor plugs in the IP turbine
blade roots, if 20 or more IP turbine blade outer shroud dust caps are
found lifting, or if 1 or more dust caps are missing.

FAA's Determination of the Effective Date

    Since there are currently no domestic operators of this engine
model, notice and opportunity for public comment before issuing this AD
are unnecessary. Therefore, a situation exists that allows the
immediate adoption of this regulation.

Differences Between the AD and the MCAI

    We have reviewed the MCAI and related service information and, in
general, agree with their substance. But we require the initial
borescope inspection to be done within 5 flight cycles, since the MCAI
required the initial inspection to be done before July 1, 2008, which
has already passed.

Comments Invited

    This AD is a final rule that involves requirements affecting flight
safety, and we did not precede it by notice and opportunity for public
comment. We invite you to send any written relevant data, views, or
arguments about this AD. Send your comments to an address listed under
the ADDRESSES section. Include ``Docket No. FAA-2008-1063; Directorate
Identifier 2008-NE-32-AD'' at the beginning of your comments. We
specifically invite comments on the overall regulatory, economic,
environmental, and energy aspects of this AD. We will consider all
comments received by the closing date and may amend this AD because of
those comments.
    We will post all comments we receive, without change, to http://
www.regulations.gov, including any personal information you provide. We
will also post a report summarizing each substantive verbal contact we
receive about this AD.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, section 106, describes the
authority of the FAA Administrator. ``Subtitle VII: Aviation
Programs,'' describes in more detail the scope of the Agency's
authority.
    We are issuing this rulemaking under the authority described in
``Subtitle VII, Part A, Subpart III, Section 44701: General
requirements.'' Under that section, Congress charges the FAA with
promoting safe flight of civil aircraft in air commerce by prescribing
regulations for practices, methods, and procedures the Administrator
finds necessary for safety in air commerce. This regulation is within
the scope of that authority because it addresses an unsafe condition
that is likely to exist or develop on products identified in this
rulemaking action.

Regulatory Findings

    We determined that this AD will not have federalism implications
under Executive Order 13132. This AD will not have a substantial direct
effect on the States, on the relationship between the national
government and the States, or on the distribution of power and
responsibilities among the various levels of government.
    For the reasons discussed above, I certify this AD:
    1. Is not a ``significant regulatory action'' under Executive Order
12866;
    2. Is not a ``significant rule'' under the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979); and
    3. Will not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
    We prepared a regulatory evaluation of the estimated costs to
comply with this AD and placed it in the AD docket.

Effective Date

    (a) This airworthiness directive (AD) becomes effective December
1, 2008.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Rolls-Royce plc (RR) RB211 Trent 553-61,
553A2-61, 556-61, 556A2-61, 556B-61, 556B2-61, 560-61, and 560A2-61
turbofan engines that have not incorporated RR Service Bulletin (SB)
No. RB.211-72-D733, dated August 21, 2002, or Revision 1 of that SB,
dated March 6, 2008. These engines are installed on, but not limited
to, Airbus A340-500 and -600 series airplanes.

Reason

    (d) European Aviation Safety Agency (EASA) AD No. 2008-0109 R1,
dated June 17, 2008, states that for RB211 Trent 500 series turbofan
engines that have not incorporated RR SB No. RB.211-72-D733, dated
August 21, 2002, or Revision 1 of that SB, dated March 6, 2008, the
unsafe condition is as follows:

    The intermediate-pressure (IP) turbine blade shrouds of the
RB211 Trent 500 series engines feature closure welds (dust caps).
Development engine testing has revealed the potential for dust caps
to crack, lift and release. The latter may potentially allow hot
annulus gas to be ingested down the core passages of IP turbine
blades. Radial inflow of annulus gas into the IP disc rim region
could cause local heating of the disc firtree, resulting in creep of
the disc material. Failure of the disc rim in creep could
simultaneously release two blades and a disc post. Failure to this
extent could be beyond the containment capabilities of the casing.
Consequently, release of the dust caps would constitute a
potentially unsafe condition.

We are issuing this AD to prevent uncontained release of IP turbine
blades and disc posts, resulting in damage to the airplane.

Actions and Compliance

    (e) Unless already done, do the following actions.
    (1) Within 5 flight cycles, on engines installed or not
installed, carry out the initial borescope inspection of the IP
turbine blade outer shroud dust caps, using Section 3,
Accomplishment Instructions of RR Alert Service Bulletin (ASB) No.
RB.211-72-AF994, Revision 1, dated September 1, 2008.
    (2) Thereafter, depending on the results of the inspection
specified in paragraph (e)(1) of this AD, follow the appropriate

SUPPLEMENTARY INFORMATION:

I. General Information

A. Does this action apply to me?

    This action is directed to the public in general.

B. What action is the Agency taking?

    EPA is announcing the availability of and soliciting public comment
on the following two draft documents that are being submitted to the
Science Advisory Committee on Chemicals (SACC) for peer review: ``Draft
Proposed Principles of Cumulative Risk Assessment under the Toxic
Substances Control Act'' and ``Draft Proposed Approach for Cumulative
Risk Assessment of High-Priority Phthalates and a Manufacturer-
Requested Phthalate under the Toxic Substance Control Act.'' The SACC
will consider and review these documents at a 4-day virtual public
meeting on May 8 to 11, 2023, which was previously announced in the
Federal Register of December 21, 2022 (87 FR 78103 (FRL-10490-01-
OCSPP)).
    This document provides instructions for accessing the materials
provided to the SACC, submitting comments, and registering to provide
oral comments at the meeting.

C. What is the Agency's authority for taking this action?

    The SACC was established by EPA in 2016 in accordance with the
Toxic Substances Control Act (TSCA), 15 U.S.C. 2625(o), as amended by
the Frank R. Lautenberg Chemical Safety for the 21st Century Act,
Public Law 114-182, June 22, 2016, to provide independent advice and
expert consultation, at the request of the Administrator, with respect
to the scientific and technical aspects of issues relating to the
implementation of TSCA. The SACC operates in accordance with the
Federal Advisory Committee Act (FACA), 5 U.S.C. 10 et seq., and
supports activities under the TSCA, 15 U.S.C. 2601 et seq., the
Pollution Prevention Act (PPA), 42 U.S.C. 13101 et seq., and other
applicable statutes.

D. What should I consider as I submit my comments to EPA?

    1. Submitting CBI. Do not submit this information to EPA through
regulations.gov or email (contact the DFO listed under FOR FURTHER
INFORMATION CONTACT for instructions). Clearly mark the part or all of
the information that you claim to be CBI. In addition to one complete
version of the comment that includes information claimed as CBI, a copy
of the comment that does not contain the information claimed as CBI
must be submitted for inclusion in the public docket. Information so
marked will not be disclosed except in accordance with procedures set
forth in 40 CFR part 2.
    2. Tips for preparing comments. When preparing and submitting your
comments, see Tips for Effective Comments at https://www.epa.gov/dockets.

II. Background

A. What is the purpose of the SACC?

    The SACC provides independent scientific advice and recommendations
to the EPA on the scientific and technical aspects of risk assessments,
methodologies, and pollution prevention measures and approaches for
chemicals regulated under TSCA. The SACC is composed of experts in
toxicology; environmental risk assessment; exposure assessment; and
related sciences (e.g., synthetic biology, pharmacology, biotechnology,
nanotechnology, biochemistry, biostatistics, physiologically based
pharmacokinetic modeling (PBPK), computational toxicology,
epidemiology, environmental fate, and environmental engineering and
sustainability). The SACC currently consists of 17 members. When
needed, the committee will be assisted by ad hoc peer reviewers with
specific expertise in the topics under consideration.

B. Why did EPA develop these documents?

    Between 2020 and 2022, EPA published final scoping documents for 20
High-Priority and three Manufacturer-Requested chemical substances for
risk evaluation under TSCA. During the scoping process, EPA received
comments from stakeholders urging the Agency to consider evaluating
several chemical substances undergoing risk evaluation for cumulative
risk to human health. TSCA does not explicitly require EPA to conduct
cumulative risk assessments (CRAs). However, TSCA does require EPA to
consider the reasonably available information and to use the best
available science and to make decisions based on the weight of
scientific evidence [15 U.S.C. 2625(h), (i), (k)]. EPA recognizes that
for some chemical substances, the best available science may indicate
that the development of a CRA is appropriate to ensure that any risks
to human health and the environment are adequately characterized.
    EPA's document entitled ``Draft Proposed Principles of Cumulative
Risk Assessment under the Toxic Substances Control Act'' describes the
fundamental principles of CRA of chemical substances and how they may
be applied within the regulatory requirements of TSCA to ensure TSCA
risk evaluations are based on the best available science and are
protective of human health. This draft document, a copy of which is
being submitted to the SACC for review and is available in the docket
for public review, is not a framework nor a guidance document on
conducting CRAs of chemical substances, and it does not address
cumulative impacts.
    Recognizing that human exposure to phthalates is widespread and
that multiple phthalates can disrupt development of the male
reproductive system in laboratory animals at potentially human relevant
doses, EPA

asked the National Research Council (NRC) of the National Academies of
Science to review the health effects of phthalates and determine
whether a cumulative risk assessment of phthalates should be conducted,
and if so, what approaches could be used for the assessment. In 2008,
NRC published their findings to EPA in a final report entitled
``Phthalates and Cumulative Risk Assessment: The Task Ahead'' (a copy
can be accessed at https://cfpub.epa.gov/si/si_public_record_report.cfm?Lab=NCEA&dirEntryId=202508. In that report,
the NRC recommended that a cumulative risk assessment should be
conducted for phthalates. EPA's document entitled ``Draft Proposed
Approach for Cumulative Risk Assessment of High-Priority Phthalates and
a Manufacturer-Requested Phthalate under the Toxic Substance Control
Act'' describes EPA's proposed approach for evaluating a subset of
High-Priority and Manufacturer-Requested phthalates for cumulative risk
to human health under TSCA based on the principles of CRA described in
EPA's draft principles document referenced previously. EPA's draft
proposed approach follows many of the recommendations made by the NRC
in 2008. This draft document, a copy of which is being submitted to the
SACC for review and is available in the docket for public review, is
not a CRA, and no risk estimates are presented. Instead, this draft
document outlines several options EPA is considering for conducting a
phthalate CRA under TSCA.
    In submitting these two draft documents to the SACC for peer
review, EPA is soliciting comments from the SACC on issues related to
chemical grouping for purposes of CRA, health outcomes related to
phthalate syndrome, and possible approaches to developing the
cumulative hazard and exposure assessment for High-Priority phthalates
and a Manufacturer-Requested phthalate.

III. Virtual Public Meeting

A. What is the purpose of this public meeting of the SACC?

    The focus of the 4-day virtual public meeting is the SACC peer
review of the following two draft documents and related public comments
received by the deadlines listed under the DATES section:
     Draft Proposed Principles of Cumulative Risk Assessment
under the Toxic Substances Control Act; and
     Draft Proposed Approach for Cumulative Risk Assessment of
High-Priority Phthalates and a Manufacturer-Requested Phthalate under
the Toxic Substance Control Act.
    EPA will provide a meeting agenda for each day of the meeting, and,
as needed, may provide updated times for each day in the meeting agenda
that will be posted in docket and on the SACC website.

B. How can I access the documents submitted for review to the SACC?

    These documents, including background documents, related supporting
materials, and draft charge questions provided to the SACC, are
available in the docket. As additional background materials become
available and are provided to the SACC, EPA will include those
additional background documents in the docket. All of these documents
will be available through https://www.regulations.gov in Docket ID No.
EPA-HQ-OPPT-2022-0918 and links on the SACC website at https://www.epa.gov/tsca-peer-review.
    After the public meeting, the SACC will prepare a meeting minutes
and final report document summarizing its recommendations to the EPA.
This document will also be added to the docket and available through
the SACC website.

C. How can I provide comments for the SACC's consideration?

    To ensure proper receipt of comments by EPA, it is imperative that
you identify Docket ID No. EPA-HQ-OPPT-2022-0918 in the subject line on
the first page of your comments and follow the instructions in this
unit.

deadlines set in the DATES section and following the instructions in
this document.
    2. Oral comments. Each individual or group wishing to make brief
oral comments to the SACC during the peer review virtual public meeting
must register to do so by the deadline set in the DATES section and
following the registration instructions that will be announced on the
SACC website by early April 2023. Oral comments will be limited to 5
minutes. In addition, each speaker should submit a copy of their
comments to the DFO prior to the meeting for distribution to the SACC
by the DFO and inclusion in the docket.

D. How can I participate in the virtual public meeting?

    Persons interested in being placed on a mailing list for future

request a copy of Advisory Circular No. 11-2A, Notice of Proposed
Rulemaking Distribution System, which describes the application
procedure.

The Proposal

    This action proposes to amend Title 14, Code of Federal Regulations
(14 CFR), Part 71 by establishing Class E airspace designated as a
surface area within a 4.4-mile radius of Mansfield Lahm Regional
Airport, Mansfield, OH, with a small segment extending from the 4.4-
mile radius of the airport to 4.8 miles northwest of the airport, to
accommodate military mission changes at the airport. Controlled
airspace is needed for the safety and management of IFR operations that
the Air National Guard units will need to conduct airdrop and other low
level training during hours when the control tower is closed.
    Class E airspace areas are published in Paragraph 6002 of FAA Order
7400.9X, dated August 7, 2013 and effective September 15, 2013, which
is incorporated by reference in 14 CFR 71.1. The Class E airspace
designation listed in this document would be published subsequently in
the Order.
    The FAA has determined that this proposed regulation only involves
an established body of technical regulations for which frequent and
routine amendments are necessary to keep them operationally current.
It, therefore, (1) is not a ``significant regulatory action'' under
Executive Order 12866; (2) is not a ``significant rule'' under DOT
Regulatory Policies and Procedures (44 FR 11034; February 26, 1979);
and (3) does not warrant preparation of a Regulatory Evaluation as the
anticipated impact is so minimal. Since this is a routine matter that
will only affect air traffic procedures and air navigation, it is
certified that this rule, when promulgated, will not have a significant
economic impact on a substantial number of small entities under the
criteria of the Regulatory Flexibility Act.
    The FAA's authority to issue rules regarding aviation safety is
found in Title 49 of the U.S. Code. Subtitle 1, Section 106 describes
the authority of the FAA Administrator. Subtitle VII, Aviation
Programs, describes in more detail the scope of the agency's authority.
This rulemaking is promulgated under the authority described in
Subtitle VII, Part A, Subpart I, Section 40103. Under that section, the
FAA is charged with prescribing regulations to assign the use of
airspace necessary to ensure the safety of aircraft and the efficient
use of airspace. This regulation is within the scope of that authority
as it would establish controlled airspace at Mansfield Lahm Regional
Airport, Mansfield, OH.

Environmental Review

    This proposal will be subject to an environmental analysis in
accordance with FAA Order 1050.1E, ``Environmental Impacts: Policies
and Procedures'' prior to any FAA final regulatory action.

GENERAL SUBJECT : Dioxins at OCPSF Sites TOPICS DISCUSSED AND ACTION TAKEN I called Gary Amendola to learn more about the processes covered by the OCPSF Category that generate dioxins, particularly in wastewater. ERG had found that most of the companies that reported dioxin water releases in the 2000 TRI manufactured PVC or vinyl chloride monomer ( VCM), and that some had chlor/ alkali plants.

Mr. Amendola confirmed that the chlor/ alkali process is a generator of dioxins, as are the ethylene dichloride ( EDC)/ VCM processes. Most plants that manufacture VCM manufacture EDC as well. The plants that manufacture both EDC/ VCM and operate chlor/ alkali facilities fall under both the OCPSF and the Inorganic Chemicals ELG regulations. PVC polymerization is a minor source of dioxins.

The Chlorine Chemistry Council continues ( CCC) continues to study dioxins releases and posts their findings on the http:// www. c3. org web site. They also provide updated data to OPPT.

I asked if dioxins are a 1990' s problem or if dioxin releases continue today. He said they are still a problem, though progress has been made. Improved controls on all sides include: segregation and treatment of contaminated water streams, upgraded air emission controls to meet MACT standards, and proper containment and disposal of sludge. Also, on the P2 side, several facilities recycle process tars rather than incinerate these materials, since incineration of these materials can form dioxin.

I asked him what other chemical processes he was familiar with that were known to generate dioxins ( other than the chlor alkali, EDC/ VCM, PVC, and TiO 2 processes), and he said that without really researching it, what came to mind are perchloroethylene manufacture ( when done by a chlorination process) and the manufacture of pentachlorophenol ( done only in the US by Vulcan Chemicals).

He also referred me to 40 CFR Part 766 ( TSCA), which addresses product testing for chemical substances with the potential to contain dioxins.
