RIN 2120-AA64

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all The
Boeing Company Model 737-400 series airplanes. This AD was prompted by
reports of cracks in the upper chord of the overwing stub beams at body
station (STA) 578 emanating from the rivet location common to the
crease beam inner chord and the overwing stub beam upper chord. This AD
requires repetitive inspections for cracking, and related investigative
and corrective actions if necessary. We are issuing this AD to prevent
the unsafe condition on these products.

DATES: This AD is effective December 30, 2016.
    The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of December 30,
2016.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would apply to all The Boeing Company
Model 737-400 series airplanes. The NPRM published in the Federal
Register on April 28, 2016 (81 FR 25360) (``the NPRM''). The NPRM was
prompted by reports of cracks in the upper chord of the overwing stub
beams at STA 578 emanating from the rivet location common to the crease
beam inner chord and the overwing stub beam upper chord. The NPRM
proposed to require repetitive inspections for cracking, and related
investigative and corrective actions if necessary. Replacement of the
overwing stub beam terminates the repetitive inspections for cracking
at the replacement location only, and post-replacement inspections are
required if the replacement is done. We are issuing this AD to detect
and correct cracking in the upper chord of the overwing stub beam
caused by high flight-cycle fatigue stresses from both pressurization
and maneuver loads. Cracking of the overwing stub beam could adversely
affect the fuselage structural integrity and result in possible
decompression of the airplane.

Comments

    We gave the public the opportunity to participate in developing
this AD. The following presents the comments received on the NPRM and
the FAA's response to each comment.

Request To Clarify Unsafe Condition Statement in the ``Discussion''
Section

    Boeing requested that, in the ``Discussion'' section of the NPRM,
that we clarify the cause of cracking in the overwing stub beams is
from high flight-cycle fatigue stresses. Boeing submitted suggested
wording.
    We agree to clarify the unsafe condition. The unsafe condition
statement in the SUMMARY section of the NPRM and paragraph (e) of the
proposed AD already specified that the cracking in the upper chord of
the overwing stub beam is caused by high flight-cycle fatigue stresses
from both pressurization and maneuver loads. However, the
``Discussion'' section of the NPRM is not restated in this final rule.
Therefore, we have not revised this final rule in this regard.

Request To Revise Paragraph (i) of the NPRM

    Boeing requested that we revise paragraph (i) of the proposed AD to
specify that the actions in that paragraph are required on airplanes
that have had an overwing stub beam replaced at STA 578 as specified in
Part 4 of the Accomplishment Instructions of Boeing Alert Service
Bulletin 737-53A1347, Original Issue, dated December 9, 2015 (``ASB
737-53A1347 Original Issue''), and not replaced with any other method.
Boeing stated that the post-replacement inspection requirements
specified in table 2 of paragraph 1.E., ``Compliance,'' of ASB 737-
53A1347 Original Issue are applicable only to a STA 578 stub beam
replacement accomplished as specified in Part 4 of the Accomplishment
Instructions of ASB 737-53A1347 Original Issue.
    We agree with Boeing's request. We have revised paragraph (i) of
this AD accordingly.

Conclusion

    We reviewed the relevant data, considered the comments received,
and determined that air safety and the public interest require adopting
this AD with the changes described previously and minor editorial
changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the
NPRM or correcting the unsafe condition; and
     Do not add any additional burden upon the public than was
already proposed in the NPRM.
    We also determined that these changes will not increase the
economic burden on any operator or increase the scope of this AD.

Related Service Information Under 1 CFR Part 51

    We reviewed ASB 737-53A1347 Original Issue. The service information
describes procedures for doing a surface high frequency eddy current
inspection for cracking in the overwing stub beam upper chord at STA
559, STA 578, and STA 601, and repairs and replacement. This service
information is reasonably available because the interested parties have
access to it through their normal course of business or by the means
identified in the ADDRESSES section.

Costs of Compliance

    We estimate that this AD affects 93 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                                     Estimated Costs

                                      inspection cycle.
--------------------------------------------------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary inspections/
replacements that would be required based on the results of the
inspection. We have no way of determining the number of aircraft that
might need these inspections/replacements:

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

    We have received no definitive data that would enable us to provide
cost estimates for the remaining on-condition actions specified in 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

    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),
    (3) Will not affect intrastate aviation in Alaska, and
    (4) 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.

    None.

(c) Applicability

    This AD applies to all the Boeing Company Model 737-400 series
airplanes, certificated in any category.

(d) Subject

    Air Transport Association (ATA) of America Code 53, Fuselage.

(e) Unsafe Condition

    This AD was prompted by reports of cracks in the upper chord of
the overwing stub beams at body station (STA) 578 emanating from the
rivet location common to the crease beam inner chord and the
overwing stub beam upper chord. We are issuing this AD to detect and
correct cracking in the upper chord of the overwing stub beam caused
by high flight-cycle fatigue stresses from both pressurization and
maneuver loads. Cracking of the overwing stub beam could adversely
affect the fuselage structural integrity and result in possible
decompression of the airplane.

(f) Compliance

    Comply with this AD within the compliance times specified,
unless already done.

(g) Inspections, Related Investigative Actions, and Corrective Actions

    At the applicable time specified in table 1 in paragraph 1.E.,
``Compliance,'' of Boeing Alert Service Bulletin 737-53A1347,
Original Issue, dated December 9, 2015 (``ASB 737-53A1347 Original
Issue''), except as required by paragraphs (j)(1) and (j)(2) of this
AD: Do a surface high frequency eddy current (HFEC) inspection for
any cracking in the overwing stub beam upper chord at STA 559, STA
578, and STA 601; and do all applicable related investigative and
corrective actions; in accordance with the Accomplishment
Instructions of ASB 737-53A1347 Original Issue, except as specified
in paragraph (j)(3) of this AD. Do all applicable related
investigative and corrective actions before further flight. Repeat
the HFEC inspection thereafter at the applicable intervals specified
in ASB 737-53A1347 Original Issue.

    Note 1 to paragraph (g) of this AD:  Deviation from the actions
specified in ASB 737-53A1347 Original Issue may affect compliance
with the fuel tank ignition prevention requirements specified in
Critical Design Configuration Control Limitation 28-AWL-11 of
Document D6-38278-CMR.

(h) Terminating Action

    Replacement of the overwing stub beam, in accordance with Part 4
of the Accomplishment Instructions of ASB 737-53A1347 Original
Issue, terminates the repetitive inspections required by paragraph
(g) of this AD at the STA 578 replacement location only. The post-
replacement inspections required by paragraph (i) of this AD are
still required at the STA 578 replacement location.

(i) Post-Replacement Inspections and Corrective Action

    For airplanes on which an overwing stub beam has been replaced
at STA 578, in accordance with Part 4 of the Accomplishment
Instructions of ASB 737-53A1347 Original Issue: At the applicable
time specified in table 2 in paragraph 1.E., ``Compliance,'' of ASB
737-53A1347 Original Issue, do a surface HFEC inspection for any
cracking in the overwing stub beam upper chord at STA 578, in
accordance with the Accomplishment Instructions of ASB 737-53A1347
Original Issue. Repeat the HFEC inspection thereafter at the
applicable intervals specified in ASB 737-53A1347 Original Issue. If
any cracking is found during any inspection required by this
paragraph, before further flight, repair the cracking using a method
approved in accordance with the procedures specified in paragraph
(j)(3) of this AD.

(j) Exceptions to Service Information

    (1) Where ASB 737-53A1347 Original Issue, specifies a compliance
time after the ``original issue date of this service bulletin,''
this AD requires compliance within the specified compliance time
after the effective date of this AD.
    (2) The Condition column of paragraph 1.E., ``Compliance,'' of
ASB 737-53A1347

Original Issue, refers to airplanes with specified total flight-
cycles ``at the original issue date of this service bulletin.'' This
AD, however, applies to the airplanes with the specified total
flight-cycles as of the effective date of this AD.
    (3) If any cracking is found during any inspection required by
this AD, and ASB 737-53A1347 Original Issue specifies to contact
Boeing for appropriate action: Before further flight, repair the
cracking or replace the stub beam, using a method approved in
accordance with the procedures specified in paragraph (l) of this
AD.

(k) No Economic Inspection Required

    This AD does not require the ``Recommended Economic Inspection''
specified in paragraph 3.B.3. of the Accomplishment Instructions of
ASB 737-53A1347 Original Issue.

(l) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Los Angeles Aircraft Certification Office
(ACO), FAA, has the authority to approve AMOCs for this AD, if
requested using the procedures found in 14 CFR 39.19. In accordance
with 14 CFR 39.19, send your request to your principal inspector or
local Flight Standards District Office, as appropriate. If sending
information directly to the manager of the ACO, send it to the
attention of the person identified in paragraph (m) of this AD.
Information may be emailed to<EMAIL_ADDRESS>    (2) Before using any approved AMOC, notify your appropriate
principal inspector, or lacking a principal inspector, the manager
of the local flight standards district office/certificate holding
district office.
    (3) An AMOC that provides an acceptable level of safety may be
used for any repair, modification, or alteration required by this AD
if it is approved by the Boeing Commercial Airplanes Organization
Designation Authorization (ODA) that has been authorized by the
Manager, Los Angeles ACO, to make those findings. To be approved,
the repair method, modification deviation, or alteration deviation
must meet the certification basis of the airplane, and the approval
must specifically refer to this AD.
    (4) Except as required by paragraph (j)(3) of this AD: For
service information that contains steps that are labeled as Required
for Compliance (RC), the provisions of paragraphs (l)(4)(i) and
(l)(4)(ii) of this AD apply.
    (i) The steps labeled as RC, including substeps under an RC step
and any figures identified in an RC step, must be done to comply
with the AD. If a step or substep is labeled ``RC Exempt,'' then the
RC requirement is removed from that step or substep. An AMOC is
required for any deviations to RC steps, including substeps and
identified figures.
    (ii) Steps not labeled as RC may be deviated from using accepted
methods in accordance with the operator's maintenance or inspection
program without obtaining approval of an AMOC, provided the RC
steps, including substeps and identified figures, can still be done
as specified, and the airplane can be put back in an airworthy
condition.

Federal Aviation Administration

14 CFR Part 97

[Docket No. 30584; Amdt. No. 3248]

Standard Instrument Approach Procedures; Miscellaneous Amendments

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: This rule amends Standard Instrument Approach Procedures
(SIAPs) for operations at certain airports. These regulatory actions
are needed because of changes in the National Airspace System, such as
the commissioning of new navigational facilities, adding of new
obstacles, or changing air traffic requirements. These changes are
designed to provide safe and efficient use of the navigable airspace
and to promote safe flight operations under instrument flight rules at
the affected airports.

DATES: This rule is effective December 13, 2007. The compliance date
for each SIAP is specified in the amendatory provisions.
    The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of December 13, 2007.

ADDRESSES: Availability of matter incorporated by reference in the
amendment is as follows:
    For Examination--
    1. FAA Rules Docket, FAA Headquarters Building, 800 Independence
Avenue, SW., Washington, DC 20591;
    2. The FAA Regional Office of the region in which the affected
airport is located;
    3. The National Flight Procedures Office, 6500 South MacArthur

airport is located.

FOR FURTHER INFORMATION CONTACT: Harry J. Hodges, Flight Procedure
Standards Branch (AFS-420), Flight Technologies and Programs Division,
Flight Standards Service, Federal Aviation Administration, Mike
Monroney Aeronautical Center, 6500 South MacArthur Blvd., Oklahoma
City, OK 73169 (Mail Address: P.O. Box 25082, Oklahoma City, OK 73125)
telephone:<PHONE_NUMBER>.

SUPPLEMENTARY INFORMATION: This rule amends Title 14, Code of Federal
Regulations, Part 97 (14 CFR part 97) by amending the referenced SIAPs.
The complete regulatory description of each SIAP is listed on the
appropriate FAA Form 8260, as modified by the National Flight Data
Center (FDC)/Permanent Notice to Airmen (P-NOTAM), and is incorporated
by reference in the amendment under 5 U.S.C. 552(a), 1 CFR part 51, and
Sec.  97.20 of Title 14 of the Code of Federal Regulations.
    The large number of SIAPs, their complex nature, and the need for a
special format make their verbatim publication in the Federal Register
expensive and impractical. Further, airmen do not use the regulatory
text of the SIAPs, but refer to their graphic depiction on charts
printed by publishers of aeronautical materials. Thus, the advantages
of incorporation by reference are realized and publication of the
complete description of each SIAP contained in FAA form documents is
unnecessary. This amendment provides the affected CFR sections and
specifies the types of SIAP and the corresponding effective dates. This
amendment also identifies the airport and its location, the procedure
and the amendment number.

The Rule

    This amendment to 14 CFR part 97 is effective upon publication of
each separate SIAP as amended in the transmittal. For safety and
timeliness of change considerations, this amendment incorporates only
specific changes

contained for each SIAP as modified by FDC/P-NOTAMs.
    The SIAPs, as modified by FDC P-NOTAM, and contained in this
amendment are based on the criteria contained in the U.S. Standard for
Terminal Instrument Procedures (TERPS). In developing these changes to
SIAPs, the TERPS criteria were applied only to specific conditions
existing at the affected airports. All SIAP amendments in this rule
have been previously issued by the FAA in a FDC NOTAM as an emergency
action of immediate flight safety relating directly to published
aeronautical charts. The circumstances which created the need for all
these SIAP amendments requires making them effective in less than 30
days.
    Because of the close and immediate relationship between these SIAPs
and safety in air commerce, I find that notice and public procedure
before adopting these SIAPs are impracticable and contrary to the
public interest and, where applicable, that good cause exists for
making these SIAPs effective in less than 30 days.

Conclusion

    The FAA has determined that this 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. For the same reason, the FAA
certifies that this amendment will not have a significant economic
impact on a substantial number of small entities under the criteria of
the Regulatory Flexibility Act.

[Docket No. CP10-50-000]

Petal Gas Storage, L.L.C.; Notice of Intent To Prepare an
Environmental Assessment for the Proposed Cavern 12A Conversion Gas
Storage Project and Request for Comments on Environmental Issues

March 19, 2010.
    The staff of the Federal Energy Regulatory Commission (FERC or
Commission) will prepare an environmental assessment (EA) that will
discuss the environmental impacts of the Cavern 12A Conversion Gas
Storage Project involving construction and operation of facilities
proposed by Petal Gas Storage, L.L.C. (Petal) in Forrest County,
Mississippi. This EA will be used by the Commission in its decision-
making process to determine whether the project is in the public
convenience and necessity.
    This notice announces the opening of the scoping process we will
use to gather input from the public and interested agencies on the
project. Your input will help the Commission staff determine what
issues need to be evaluated in the EA. Please note that the scoping
period will close on April 23, 2010.
    This notice is being sent to the Commission's current environmental
mailing list for this project. State and local government
representatives are asked to notify their constituents of this proposed
project and encourage them to comment on their areas of concern.
    If you are a landowner receiving this notice, you may be contacted
by a pipeline company representative about the acquisition of an
easement to construct, operate, and maintain the proposed facilities.
The company would seek to negotiate a mutually acceptable agreement.
However, if the project is approved by the Commission, that approval
conveys with it the right of eminent domain. Therefore, if easement
negotiations fail to produce an agreement, the pipeline company could
initiate condemnation proceedings in accordance with state law.
    A fact sheet prepared by the FERC entitled ``An Interstate Natural
Gas Facility On My Land? What Do I Need To Know?'' was attached to the
project notice that Petal provided to landowners. This fact sheet
addresses a number of typically asked questions, including the use of
eminent domain and how to participate in the Commission's proceedings.
It is also available for viewing on the FERC Web site (http://
www.ferc.gov).

Summary of the Proposed Project

    Petal proposes to purchase an existing salt-brine storage cavern
(12A) from an affiliate, and convert it into a natural gas storage
cavern. The proposed facilities would mostly be within Petal's existing
storage field on the Petal Salt Dome. The project would increase
Petal's firm natural gas storage capacity to meet anticipated growing
demand for storage services in the Southeastern United States. Petal
would rework the existing well and expand the underground storage
capacity of Cavern 12A through solution mining. Cavern 12A would have
an overall capacity of about 8.2 billion cubic feet (Bcf), consisting
of 5.0 Bcf of working gas and 3.2 Bcf of cushion gas.
    The proposed facilities include:
     Existing Cavern 12A to be converted from brine storage to
natural gas storage;
     New 16-inch-diamter pipeline, about 1,525-feet-long,
connecting Cavern 12A with Petal's existing withdrawal header between
existing Caverns 6 and 7; and
     New appurtenant facilities grouped near existing Petal
Compressor Station 2, including a withdrawal separator, heat exchanger,
hot oil pump, pressure regulator, and Triethylene Glycol contactor and
regeneration skid.
    The general location of the proposed facilities is shown in
Appendix 1.\1\
---------------------------------------------------------------------------

    \1\ The appendices referenced in this notice are not being
printed in the Federal Register. Copies of appendices were sent to
all those receiving this notice in the mail and are available at
http://www.ferc.gov using the link called ``eLibrary'' or from the
Commission's Public Reference Room, 888 First Street, NE.,
Washington, DC 20426, or call<PHONE_NUMBER>. For instructions on
connecting to eLibrary, refer to the last page of this notice.
---------------------------------------------------------------------------

Land Requirements for Construction

    Petal estimated that about 39 acres of land would be disturbed by
construction of the proposed facilities. About 5.8 acres would be
retained for Petal's permanent operational easement, following
construction. The remaining temporary construction acreage would be
restored to its former condition and uses.

The EA Process

    The National Environmental Policy Act (NEPA) requires the
Commission to take into account the environmental impacts that could
result from an action whenever it considers the issuance of a
Certificate of Public Convenience and Necessity. NEPA also requires us
\2\ to discover and address concerns the public may have about
proposals. This process is referred to as ``scoping.'' The main goal of
the scoping process is to focus the analysis in the EA on the important
environmental issues. By this notice, the Commission requests public
comments on the scope of the issues to be addressed in the EA. All
comments received will be considered during the preparation of the EA.
---------------------------------------------------------------------------

    \2\ ``We,'' ``us,'' and ``our'' refer to the environmental staff
of the Commission's Office of Energy Projects.
---------------------------------------------------------------------------

    In the EA we will discuss impacts that could occur as a result of
the construction and operation of the proposed project under these
general headings:
     Geology and soils;
     Water resources and wetlands;
     Vegetation and wildlife;
     Cultural resources;
     Land use;
     Air quality and noise; and
     Safety and reliability.

    We will also evaluate reasonable alternatives to the proposed
project or portions of the project, and make recommendations on how to
lessen or avoid impacts on various resources. Our independent analysis
of the environmental issues will be presented in the EA.
    The EA will be placed in the public record and, depending on the
comments received during the scoping process, may be published and
distributed to the public. A comment period will be allotted if the EA
is published for review. We will consider all comments on the EA before
we make our recommendations to the Commission. To ensure your comments
are considered, please carefully follow the instructions in the Public
Participation section of this notice (below).
    With this notice, we are asking agencies with jurisdiction and/or
special expertise with respect to environmental issues to formally
cooperate with us in the preparation of the EA. These agencies may
choose to participate once they have evaluated the proposal relative to
their responsibilities. Agencies that would like to request cooperating
agency status should follow the instructions for filing comments
provided under the Public Participation section of this notice (below).

Consultations Under Section 106 of the National Historic Preservation
Act

    In accordance with the Advisory Council on Historic Preservation's
implementing regulations, we are using this notice to solicit the views
of the public on the project's potential effects on historic
properties.\3\ We will document our findings on the impacts on cultural
resources, and summarize the status of consultations under section 106
of the National Historic Preservation Act in our EA.
---------------------------------------------------------------------------

    \3\ The Advisory Council on Historic Preservation's regulations
are at Title 36, Code of Federal Regulations, Part 800. Historic
properties are defined in those regulations as any prehistoric or
historic district, site, building, structure or object included in
or eligible for inclusion in the National Register of Historic
Places.
---------------------------------------------------------------------------

Public Participation

    You can make a difference by providing us with your specific
comments or concerns about the project. Your comments should focus on
the potential environmental effects, reasonable alternatives, and
measures to avoid or lessen environmental impacts. The more specific
your comments, the more useful they will be. To ensure that your
comments are timely and properly recorded, please send your comments so
that they will be received in Washington, DC on or before April 23,
2010.
    For your convenience, there are three methods which you can use to
submit your written comments to the Commission. The Commission
encourages electronic filing of comments and has expert eFiling staff
available to assist you at<PHONE_NUMBER> or<EMAIL_ADDRESS>    (1) You may file your comments electronically by using the Quick
Comment feature, which is located at http://www.ferc.gov under the link
called ``Documents and Filings.'' Quick Comment is an easy method for
interested persons to submit text-only comments on a project;
    (2) You may file your comments electronically by using the
``eFiling'' feature that is listed under the ``Documents and Filings''
link. eFiling involves preparing your submission in the same manner as
you would if filing on paper, and then saving the file on your
computer's hard drive. You will attach that file to your submission.
New eFiling users must first create an account by clicking on the links
called ``Sign up'' or ``eRegister.'' You will be asked to select the
type of filing you are making. A comment on a particular project is
considered a ``Comment on a Filing;'' or
    (3) You may file a paper copy of your comments at the following
address: Kimberly D. Bose, Secretary, Federal Energy Regulatory
Commission, 888 First Street, NE., Room 1A, Washington, DC 20426.

Environmental Mailing List

    The environmental mailing list includes federal, state, and local
government representatives and agencies; elected officials;
environmental and public interest groups; Indian tribes that
historically used or occupied the project area; other interested
parties; and local libraries and newspapers. This list also includes
all affected landowners (as defined in the Commission's regulations)
who are potential right-of-way grantors, whose property may be used
temporarily for project purposes, or who own homes within certain
distances of aboveground facilities, and anyone who submits comments on
the project. We will update the environmental mailing list as the
analysis proceeds to ensure that we send the information related to
this environmental review to all individuals, organizations, and
government entities interested in and/or potentially affected by the
proposed project.
    If the EA is published for distribution, copies will be sent to the
environmental mailing list for public review and comment. If you would
prefer to receive a paper copy of the document instead of the CD
version or would like to remove your name from the mailing list, please
return the attached Information Request (Appendix 2).

Becoming an Intervenor

    In addition to involvement in the EA scoping process, you may want
to become an ``intervenor,'' which is an official party to the
Commission's proceeding. Intervenors play a more formal role in the
process and are able to file briefs, appear at hearings, and be heard
by the courts if they choose to appeal the Commission's final ruling.
An intervenor formally participates in the proceeding by filing a
request to intervene. Instructions for becoming an intervenor are
included in the User's Guide under the ``e-filing'' link on the
Commission's Web site.

Pesticide Registration ( PR) Notice 2001 5 NOTICE TO MANUFACTURERS, FORMULATORS, PRODUCERS AND REGISTRANTS OF PESTICIDE PRODUCTS ATTENTION: Persons Responsible for Registration of Pesticide Products SUBJECT: Guidance for Pesticide Registrants on Pesticide Resistance Management Labeling The Office of Pesticide Programs ( OPP) of the United States Environmental Protection Agency ( EPA) announces purely voluntary pesticide resistance management labeling guidelines based on mode/ target site of action for agricultural uses of herbicides, fungicides, bactericides, insecticides, and acaricides. This document provides acceptable schemes of classification of pesticides according to their mode/ target site of action ( Appendices I III), a standard format for showing group identification symbols on the end use product labels, and examples of resistance management labeling in the use directions. These guidelines are the result of a joint effort of the U. S. and Canada under the North American Free Trade Agreement ( NAFTA).

I. Scope The mode/ target site of action symbols and pesticide resistance management labeling statements described in this Pesticide Registration ( PR) notice are voluntary. This PR Notice is directed to Registrants of herbicide, fungicide, bactericide, insecticide, and acaricide products that are intended for general agricultural use, including both new products and old ( existing) products and is not mandatory. EPA does not expect to require the use of this labeling in any individual licensing proceeding. However, EPA believes that this approach to resistance management is sound and would be highly beneficial to pesticide manufacturers and pesticide users. EPA is hopeful that Registrants will embrace this approach and work with EPA to implement it for all relevant products. EPA believes this approach is an important element of international harmonization. 1Common mechanism of toxicity for purposes of cumulative human health risk assessment under FFDCA is described in detail in EPA's guidance document " Guidance for identifying pesticide chemicals and other substances that have a common mechanism of toxicity" located at http:// www. epa. gov/ fedrgstr/ EPA PEST/ 1999/ February/ Day 05/ 6055. pdf.

2 II. Introduction The United States Environmental Protection Agency ( EPA) and the Pest Management Regulatory Agency of Canada ( PMRA) are committed to long term pest resistance management through pesticide resistance management and alternative pest management strategies. Under the auspices of the North American Free Trade Agreement ( NAFTA), the U. S. and Canada have joined together to develop and publish guidelines for voluntary pesticide resistance management labeling for implementation in North America. The development of these guidelines is part of the activities of the Risk Reduction Subcommittee of the NAFTA Technical Working Group on Pesticides. A uniform approach across North America will help reduce the development of pest resistance and support joint registration decisions by providing consistency in resistance management labeling being considered for approval in any or all of the NAFTA countries.

Pesticide resistance is defined for the purposes of this document as an heritable and significant decrease in the sensitivity of a pest population to a pesticide that is shown to reduce the field performance of pesticides. Pests covered by this initiative include insects, mites, weeds, and fungi and bacteria which cause plant disease. The management of pesticide resistance development is an important part of sustainable pest management and this, in conjunction with alternative pest management strategies and Integrated Pest Management ( IPM) programs, can make significant contributions to reducing risks to humans and the environment. In support of these goals, the purpose of this document is to provide guidance on resistance management labeling based on mode/ target site of action to Registrants. A consequence of this PR notice will be to provide guidance to users about pesticide resistance management strategies based on mode/ target site of action.

Pesticides are important pest management tools. Many pesticides have gradually lost their effectiveness due to the development of resistance by pests they once controlled. An important pesticide resistance management strategy is to avoid the repeated use of a particular pesticide, or pesticides that have a similar target site of action as the pest control mechanism in the same field. Mode/ target site of action refers to the biochemical mechanism by which the pesticide acts on the pest and should not be interpreted to imply that these chemicals share a common mechanism for purposes of cumulative human health risk assessment under the Federal Insecticide, Fungicide, and Rodenticide Act ( FIFRA) and Federal Food Drug and Cosmetics Act ( FFDCA) as amended by the Food Quality and Protection Act of August 3, 19961. One pest control strategy is rotating pesticides and/ or using tank mixtures or premixes with different mode/ target sites of action. This will delay the onset of resistance, 3 as well as slow the development and subsequent buildup of resistance, without resorting to increased rates and frequency of application, and ultimately, will prolong the useful life of many pesticides.

A resistance management strategy should also consider cross resistance between pesticides with different modes/ target sites of action. Pests may develop cross resistance to pesticides based on mode/ target site of action. This voluntary labeling initiative will provide pesticide users with easy access to important information regarding pesticide mode/ target site of action, the cornerstone of most resistance management programs.

To ensure consistency in pesticide grouping and labeling, and to contribute to the management of the pesticide resistance problem, the following guidelines have been developed for agricultural uses of herbicides, fungicides, bactericides, insecticides, and acaricides. The following classification schemes are based on mode/ target site of action.

III. Presentation and Format of Resistance Management Information on Pesticide Labels The use of target site of action symbols and pesticide resistance management statements in this PR Notice is voluntary. Canada and Australia have adopted color schemes that are consistent across target site of action groupings. The Canadian system is voluntary and is analogous to the guidelines presented by EPA. The Australian system is mandatory. If the approach described here is used, the following format and presentation are recommended.

A. Mode/ Target Site of Action Grouping and Identification Symbol Herbicides, fungicides, bactericides, insecticides, and acaricides are separately grouped according to their mode/ target site of action by various technical/ research committees consisting of representatives of the pesticide industry, researchers, extension specialists and regulatory officials. The Agency based its mode/ target site of action groupings on those previously defined by the following industry technical committees: Herbicide Resistance Action Committee ( HRAC), Fungicide Resistance Action Committee ( FRAC), and Insecticide Resistance Action Committee ( IRAC). Information on each of these organizations, the mode/ target site of action groups, and recommended resistance management strategies may be found at the following web site: http:// www. gcpf. org. Additional guidance for herbicides was provided by the Weed Science Society of America ( WSSA). The WSSA and HRAC have sponsored Dr. Ian Heap to set up a web site dedicated to ongoing surveys of herbicide resistance world wide: http:// www. weedscience. com. This web site includes information on identifying mode/ target site of action for each herbicide using both the HRAC alphabetic classification system and the WSSA numerical classification system that is currently in use by Canada and will be used by EPA. The target site of action groups plus the identifier numbers for herbicides, fungicides/ bactericides, and insecticides/ acaricides are located in Appendix I, II and III, respectively.

If used, the target site of action identification symbol should be shown on all end use product 4 labels ( except products for homeowner/ residential uses) in a standard format as outlined below, and should:

1. be located in the upper right quadrant of the front panel surrounded by a black ( or suitable color) rectangle, but should not conflict with the required placement of any other front panel element;

2. be in black and on a white background ( or other suitable contrasting colors) except the target site of action number( s) which should be white on a black background with a clear white gap ( or other suitable contrasting colors) between the target site of action numbers; and 3. include the words " GROUP" and " HERBICIDE" ( or " FUNGICIDE" or " INSECTICIDE") in capital letters, and between these words the number( s) representing the target site of action group( s) of each active ingredient( s). Where a product has two or more active ingredients, and these are represented by two or more sites of action, then two or more appropriate target site of action identifier numbers should be used. For products containing an active ingredient that has multiple sites of action, the letter " M" should be used to represent the target site of action group. Alternatively, if sites of action are known, the label should specify each target site of action by the appropriate number.

Example 1: Product containing one active ingredient represented by one target site of action.

GROUP 1 HERBICIDE Example 2: Product containing two or more active ingredients represented by two or more target sites of action.

GROUP 1 2 3 HERBICIDES Example 3: Pre mixture of a fungicide and an insecticide.

GROUP 1 FUNGICIDE GROUP 2 INSECTICIDE 5 B. Resistance Management Statements Use of the resistance management statements described below is voluntary. If used, these statements should be included in the general use directions for end use products ( except products for homeowner/ residential uses) for the control of weeds, plant pathogens ( diseases), insects and mites under the heading " Resistance Management Recommendations." The section " Resistance Management Recommendations" should be segregated under the " General" portion of the " Use Directions" and preferably boxed to distinguish these statements from mandatory statements on the pesticide label.

The examples of standard resistance management labeling statements listed below provide a general framework of actions that have been noted to be useful in mitigating pest resistance and should be used as appropriate. The development and use of specific resistance management strategies and labeling statements should be developed on the basis of scientific data on a product/ class specific basis based on the pesticide product/ class, crop, and pest( s) combination and the use history for the pesticide and crop/ pest( s) combination. These strategies and labeling statements should be included in any product specific literature. Efforts should be made to include all appropriate active ingredients and products. In addition to known pest resistance to ( a) pesticide( s), appropriate resistance management labeling language should be provided for situations in which pest resistance has not occurred to a given pesticide product or to a given pesticide class, but is part of a good pesticide stewardship program to delay the onset of pest resistance.

1. Herbicides The following general herbicide resistance management labeling statements may be applicable.

"( Name of product) is a Group ( target site of action group number) herbicide. Any weed population may contain or develop plants naturally resistant to ( name of product) and other Group ( target site of action group number) herbicides. Weed species with acquired resistance to Group ( target site of action group number) may eventually dominate the weed population if Group ( target site of action group number) herbicides are used repeatedly in the same field or in successive years as the primary method of control for targeted species. This may result in partial or total loss of control of those species by ( name of product) or other Group ( target site of action group number) herbicides."

" To delay herbicide resistance consider:

° Avoiding the consecutive use of ( name of product) or other target site of action Group ( target site of action group number) herbicides that 6 have a similar target site of action, on the same weed species.

° Using tank mixtures or premixes with herbicides from different target site of action Groups as long as the involved products are all registered for the same use, have different sites of action, and are both effective at the tank mix or prepack rate on the weed( s) of concern.

° Basing herbicide use on a comprehensive IPM program.

° Monitoring treated weed populations for loss of field efficacy.

° Contacting your local extension specialist, certified crop advisors, and/ or manufacturer for herbicide resistance management and/ or integrated weed management recommendations for specific crops and resistant weed biotypes."

If available to company, consider including: ° " For further information or to report suspected resistance, you may contact ( company representatives) at toll free number: ________ or at Internet site: ."

Note: The above are general statements for products containing one or more active ingredients from the same target site of action group, e. g., tank mixes and premix products. For products containing two or more active ingredients from different target site of action groups, the following general statements may be applicable. For example:

"( Name of product) is both a Group ( target site of action group number) and a Group ( target site of action group number) herbicide. Any weed population may contain or develop plants naturally resistant to Group ( target site of action group number) and/ or Group ( target site of action group number) herbicides. Weed species with acquired resistance to Group ( target site of action group number) and/ or Group ( target site of action group number) herbicides may eventually dominate the weed population if Group ( target site of action group number) and/ or Group ( target site of action group number) herbicides are used repeatedly in the same field or in successive years as the primary method of control for targeted species. This may result in partial or total loss of control of those species by ( name of product) or other Group ( target site of action group number) and/ or Group ( target site of action group number) herbicides." [ Follow with resistance management 7 labeling statements.]

2. Fungicides and Bactericides The following general fungicide/ bactericide resistance management labeling statements may be applicable.

"( Name of product) contains a Group ( target site of action group number) ( fungicide/ bactericide). Fungal isolates/ bacterial strains with acquired resistance to Group ( target site of action group number) may eventually dominate the fungal/ bacterial population if Group ( target site of action group number) fungicides/ bactericides are used repeatedly in the same field or in successive years as the primary method of control for targeted species. This may result in partial or total loss of control of those species by ( name of product) or other Group ( target site of action group number)."

" To delay fungicide/ bactericide resistance consider:

° Avoiding the consecutive use of ( name of product) or other target site of action Group ( target site of action group number) fungicides/ bactericides that have a similar target site of action, on the same pathogens.

° Using tank mixtures or premixes with fungicide/ bactericides from different target site of action Groups as long as the involved products are all registered for the same use and are both effective at the tank mix or prepack rate on the pathogen( s) of concern.

° Basing fungicide/ bactericide use on a comprehensive IPM program.

° Monitoring treated fungal/ bacterial populations for loss of field efficacy.

° Contacting your local extension specialist, certified crop advisors, and/ or manufacturer for fungicide/ bactericide resistance management and/ or IPM recommendations for specific crops and resistant pathogens."

4. Pesticides of Unspecified Groups or Pesticides Without History of Resistance Some herbicides, fungicides, bactericides, insecticides, and acaricides have not been assigned to any particular target site of action group, or are not on the lists in this 10 document because of the lack of clear understanding of their target site of action or the absence of a history of resistance development for the product, e. g., nematicides. Also, in general, herbicides with an unknown target site of action and/ or multiple sites of action historically have been less prone to the development of weed resistance.

Registrants are encouraged to establish the appropriate group identifications for their products in consultation with representatives of the pesticide industry, technical working groups such as the WSSA, IRAC, FRAC, HRAC, researchers, extension specialists, crop consultants, and regulatory officials. Appropriate resistance management statements for the product, i. e., herbicides, fungicides, bactericides, insecticides, and/ or acaricides, should be developed similar to those described above.

IV. Addition or Changes to Target Site of Action Lists The pesticide lists will be updated from time to time ( approximately annually) to include product names and/ or new/ revised target site of action classification. This will be done in consultation with WSSA, IRAC, HRAC, and FRAC and other appropriate organizations. Updated lists will be posted on the Office of Pesticide Program's home page. Hard copies will be made available from the Agency upon request.

V. Implementation The implementation of this program is purely voluntary by the pesticide industry and is part of a NAFTA labeling harmonization effort on pesticide resistance management with Canada. Canada's guidelines, Regulatory Directive DIR99 06, for voluntary pesticide resistance management labeling were finalized, October 6, 1999. Canada has set a target date of January 1, 2004 for implementation of its pesticide resistance management labeling guidelines. As part of the Agency's harmonization efforts on pesticide resistance management labeling with Canada, Registrants are encouraged to add the resistance management grouping symbols and statements to product labels in a similar time frame. Registration and reregistration approval will not be contingent on inclusion of either the resistance management labeling statements or the mode/ target site of action classification. However, in view of the importance of resistance management to a long term pest management strategy, the EPA will evaluate the industry's implementation of resistance management labeling. The process for how to change labels is described in Section VI.

Resistance management strategies are not requirements for the user, even if the product bears resistance management statements or the mode/ target site of action classification. Failure to follow the recommended resistance management strategies on the labeling is not regarded by EPA as a misuse of the product. 11 VI. How to Change Labels No registrant will be required to add resistance management statements or appropriate mode/ target site of action classification to the product label. Because pesticide resistance management is important, though, EPA encourages Registrants to include both the resistance management statements and the mode/ target site of action classification on the product label whenever submitting new or revised labeling to the Agency for registration or reregistration. In order to make it easy for Registrants to add resistance management statements and the target site of action classification to their product labels, and because so many products may be affected, EPA will permit the statements and the target site of action classification to be added by notification.

Registrants who wish to add the appropriate mode/ target site of action classification and the resistance management statements may do so by notification to the Agency, provided that:

1. The statements as worded and the appropriate mode/ target site of action classification as stated in this notice are used. The resistance management statements and mode/ target site of action classification system in this notice have been developed in conjunction with international efforts including industry/ academic technical working groups, and Registrants are urged to consider adopting it as written.

OR 2. Similarly worded statements are used. EPA recognizes that Registrants may wish to use wording of their own development or more specific resistance management strategies. Therefore, EPA will permit the addition of similarly worded statement also by notification. Wording may be varied to accommodate the needs of the individual products. However, the following information is considered important to user understanding, and EPA strongly encourages Registrants to include the following points in their statements ( in addition to the mode/ target site of action Group classification on the front panel):

a. The product is classified in one or more listed mode/ target site of action Groups;

b. The target pest species may develop natural resistance to the pesticide product and resistant species may become dominant in any given field situation if the product is used repeatedly;

c. If resistance develops, the product may lose effectiveness in controlling the pest species.

d. Effective resistance management can delay resistance:

Avoid repeated or sequential use of products in the same Group; Use tank mixes or premixes from a different Group; 12 Use an effective IPM program; Monitor [ pest, weed, insect, etc.] populations for loss of efficacy; Contact your extension specialist, certified crop consultant, or manufacturer for the latest resistance management information; Contact the producer to report loss of efficacy.

EPA emphasizes that the recommended resistance management statements and mode/ target site of action Group classification number are not mandatory for users, but provide information and guidance that will benefit users. Registrants are strongly encouraged to use the mode/ target site of action classification system and to use a heading such as " Resistance Management Recommendations" and to clearly segregate the information from mandatory use instructions by presentation, such as by boxing the statements. This will ensure that users are fully informed about resistance management, while making clear that compliance is not required.

EPA will work with existing pesticide education efforts that will be used to implement the guidance of this PR notice such as the WSSA extension committee, State Pesticide Applicator Training Programs, federal and state extension programs, IRAC, HRAC, and FRAC to demonstrate how effective resistance management strategies benefit users, the agricultural community, and environmental groups. EPA intends to develop a Fact Sheet about effective resistance management strategies that will provide more extensive information about our efforts.

Scope of Policy This PR Notice provides guidance to EPA, to pesticide Registrants and applicants, and to the public. As a guidance document, this notice is not binding on either EPA or pesticide Registrants, and EPA may depart from the guidance provided in individual circumstances and without notice. For the matters covered by this particular PR Notice, EPA does not expect to require that any Registrant adopt the labeling set forth here as part of any individual licensing decision or action. However, if any Registrant seeks to use the language set forth here in the manner and circumstances described here, EPA does generally expect to find such language acceptable in any licensing proceeding. However, EPA believes that the approach to resistance management described in this PR Notice is sound and would be highly beneficial to pesticide manufacturers and pesticide users. EPA is hopeful that Registrants will embrace this approach and work with EPA to implement it for all relevant products. EPA believes this approach is an important element of international harmonization.

The classification scheme was developed in consultation with the Insecticide Resistance Action Committee ( IRAC) ( see http:// www. gcpf. org). IRAC is a specialist technical working group of the Global Crop Protection Federation ( GCPF). It is recognized that resistance of insects and mites to insecticides and acaricides can also result from enhanced metabolism, reduced penetration or behavioral changes that are not linked to any target site of action classification, but are specific for individual chemicals or chemical groups. All members of a class may not be cross resistant based merely on mode/ target site of action. Most biological insecticides are not included in this Appendix because they are thought not to pose as great a concern for resistance development. Microbial products involving Cry delta endotoxins from Bacillus sp. are included as well as certain biochemical products.

2. Not all members of this class have been shown to be cross resistant. Different resistance mechanisms that are not linked to target site of action, such as enhanced metabolism, are common for this group of chemicals. Alternation of compounds from different subgroups within this class may be an acceptable part of an integrated pest management program.

3. Products containing multiple toxins would be differentiated from those containing single toxins only. This would be done by adding a suffix of " m" for multiple toxin products and " s" for single toxin products. Products containing spores would be differentiated from those without spores by adding "+" for sporecontaining products and "" for those products which do not contain spores. For example, B. thuringiensis subsp. kurstaki product containing multiple toxins and spores could be designated as Group 11Dm+, while the same product without spores and expressing only one toxin would be designated as Group 11Ds.

4. There are no U. S. registered uses of chlorfenapyr. 22 Voltage dependent sodium channel blocker Oxadiazine indoxacarb
