Executive Summary

Acute and chronic aggregate dietary (food and drinking water) exposure and risk assessments were conducted using the Dietary Exposure Evaluation Model DEEM-FCID™, Version 2.03 which uses food consumption data from the U.S. Department of Agriculture’s Continuing Surveys of Food Intakes by Individuals (CSFII) from 1994-1996 and 1998.  These dietary exposure and risk assessments for coumaphos include the following: (1) Section 3 requests for coumaphos in honey; (2) new acute toxicological endpoint; (3) and the latest PDP monitoring data for beef and milk.

Acute Dietary (Food and Drinking Water) Exposure Results and Characterization

A partially refined acute dietary exposure assessment was conducted to estimate the dietary exposure and risk associated with the proposed Section 3 registration of coumaphos on honey.  The acute dietary exposure assessment incorporated 2002 PDP monitoring data for beef and 2004 PDP monitoring data for milk.  Field trial data were used for honey to support the proposed use pattern.  The dietary exposure assessment assumes 100% crop treated for the acute analysis.

The GENEEC and SCI-GROW screening models were used to estimate surface water and groundwater concentrations of coumaphos and its oxygen analog, coumaphoxon.  Tier 1 GENEEC screening model, representing a worst-case runoff scenario for pesticides in surface water, was used to estimate the upper-bound concentrations in surface water.  Total coumaphos (coumaphos + coumaphoxon) acute estimated environmental concentrations in drinking water derived from surface water sources are not likely to exceed 1.86 ppb.

The acute aggregate dietary exposure estimates are below HED’s level of concern (<100 % aPAD) for the U.S. population and all population subgroups.  Combined dietary exposure from food and drinking water at the 99.9th percentile of exposure is 15% of the aPAD for the U.S. population and 38% of the aPAD for all infants (<1 yr), the most highly exposed population subgroup.

Chronic Dietary (Food and Drinking Water) Exposure Results and Characterization

A partially refined chronic dietary exposure assessment was conducted to estimate the dietary risks associated with the registration of coumaphos.  The chronic dietary exposure assessment incorporated the latest PDP monitoring data, average field trial data for honey and assumed 100% crop treated.  Total coumaphos (coumaphos + coumaphoxon) chronic estimated environmental concentrations in drinking water derived from surface water sources are not likely to exceed 0.41 ppb.

The chronic aggregate dietary exposure estimates are below HED’s level of concern (< 100% of the cPAD) for the U.S. population and all population subgroups. Combined dietary exposure from food and drinking water is 6% of cPAD for the U.S. population and 13% of the cPAD for all infants (<1 yr), the most highly exposed population subgroup.

Cancer Dietary (Food and Drinking Water) Exposure Results and Characterization

Coumaphos was classified as “not likely to be a human carcinogen,” therefore a cancer dietary assessment was not performed.

I. Introduction

Dietary risk assessment incorporates both exposure and toxicity of a given pesticide.  For acute and chronic assessments, the risk is expressed as a percentage of a maximum acceptable dose (i.e., the dose which HED has concluded will result in no unreasonable adverse health effects).  This dose is referred to as the population adjusted dose (PAD).  The PAD is equivalent to point of departure (POD; NOAEL, LOAEL, e.g.) divided by the required uncertainty or safety factors.

For acute and non-cancer chronic exposures, HED is concerned when estimated dietary risk exceeds 100% of the PAD.  References which discuss the acute and chronic risk assessments in more detail are available on the EPA/pesticides web site:  “Available Information on Assessing Exposure from Pesticides, A User’s Guide,” 21-JUN-2000, web link:      HYPERLINK "http://www.epa.gov/fedrgstr/EPA-PEST/2000/July/Day-12/6061.pdf"  http://www.epa.gov/fedrgstr/EPA-PEST/2000/July/Day-12/6061.pdf  ; or see SOP 99.6 (20-AUG-1999).

The most recent dietary risk assessment for coumaphos was conducted by W. Cutchin (13-OCT-2000, D267978).

II. Residue Information

Coumaphos (O-[3-chloro-4-methyl-2-oxo-2H-1-benzopyran-7-yl] O,O-diethyl phosphorothioate) is an organophosphate insecticide/acaricide currently used for the control of mites and insects on livestock.  Permanent tolerances are established for the residues of coumaphos and its oxygen analog (coumaphos-OP) at 1.0 ppm in fat, meat, and meat byproducts of cattle, goats, hogs, horses, and sheep, along with a tolerance at 0.5 ppm in milk fat (40CFR §180.189[a]).  Time-limited tolerances have also been established for residues of coumaphos and its oxygen analog at 0.1 and 100 ppm, respectively, in honey and honeycomb (40CFR §180.189[b]), associated with Section 18 emergency uses in beehives; these tolerances are set to expire on 12/31/2007.

No plant metabolism data are required as coumaphos is not registered for use on plants. The nature of the residue in livestock is understood, based on an adequate cow metabolism study reflecting dermal dosing.  The residues of concern in livestock are coumaphos and its oxygen analog.  The existing animal metabolism data are adequate for purposes of the proposed use on honeybees.  The residues of concern in honeybee products (honey and honeycomb) are coumaphos and coumaphos-OP.

Residue Data used for Acute and Chronic Dietary Assessments

Interregional Research Project #4 (IR-4) has submitted a petition (PP#2E6504) proposing a Section 3 registration for the use of coumaphos-impregnated strips in beehives for the control of varroa mites and small hive beetles.  The strips (CheckMite+ Bee Hive Pest Control Strips) contain 10% coumaphos, the active ingredient (ai), by weight.  The proposed label would allow for use of up to two 10% strips hung in the hive’s brood chamber for control of varroa mites, and the concurrent use of another 10% strip attached to the bottom board for control of small hive beetles.  The strips could remain in the hive for up to 45 days, and the application could be made at anytime during the year, including during honey flow (honey accumulation).  HED  SEQ CHAPTER \h \r 1  recommends the establishment of permanent tolerances for the combined residues of coumaphos and its oxygen analog at 0.15 ppm in honey, and 45 ppm in honeycomb (W. Drew, D036501).

Honey (partially blended): The entire distribution of field trial residues (0.034, 0.034, 0.071, 0.032, 0.055, 0.034, 0.074, 0.037, 0.052, 0.020, and 0.021 ppm) from two 10% strips (1x rate) at 0-13 days were used at 100% crop treated in the acute dietary analysis.  An average field trial residue value of 0.042 ppm was calculated for chronic dietary assessment.  See Table 1 below.

Beef (Adipose): PDP data from 2002 were used for beef adipose.  A total of 301 samples were analyzed for coumaphos and coumaphos oxygen analog.  Coumaphos and coumaphos oxygen analog were not detected in any samples. An anticipated residue value of 0.00375 ppm which represents ½ the combined LOQ (limit of quantitation) values of coumaphos and its oxygen analog was used for the acute and chronic dietary analyses and 100% crop treated was assumed.

Beef (liver): PDP data from 2002 were used for beef liver.  A total of 313 samples were analyzed for coumaphos and coumaphos oxygen analog.  Coumaphos and coumaphos oxygen analog were not detected in any samples. An anticipated residue value of 0.00375 ppm which represents ½ the combined LOQ (limit of quantitation) values of coumaphos and its oxygen analog was used for the acute and chronic dietary analyses and 100% crop treated was assumed.

Beef (muscle): PDP data from 2002 were used for beef liver.  A total of 310 samples were analyzed for coumaphos and coumaphos oxygen analog.  Coumaphos and coumaphos oxygen analog were not detected in any samples.  An anticipated residue value of 0.00375 ppm which represents ½ the combined LOQ (limit of quantitation) values of coumaphos and its oxygen analog was used for the acute and chronic dietary analyses and 100% crop treated was assumed.

Milk: PDP data from 2004 were used for milk.  A total of 739 samples were analyzed for coumaphos and coumaphos oxygen analog.  Coumaphos and coumaphos oxygen analog were not detected in any samples.  An anticipated residue value of 0.00013 ppm which represents ½ the combined LOQ (limit of quantitation) values of coumaphos and its oxygen analog was used for the acute and chronic dietary analyses and 100% crop treated was assumed.

Processing Factors:   	An adequate honey processing study is available, which used samples of raw honey fortified with coumaphos, and samples of raw honey with field-incurred residues of coumaphos.  Following processing of raw honey by heating and filtration, coumaphos residues were reduced in the final honey fractions by 0.5x.  A default processing factor for dried beef of 1.92 was also used.

Organophosphate Pesticides, and Completion of the Tolerance Reassessment and

Reregistration Eligibility Process for the Organophosphate Pesticides; D. Edwards, 31-JUL-2006.

The GENEEC and SCI-GROW screening models were used to estimate surface water and groundwater concentrations of coumaphos and its oxygen analog, coumaphoxon.  This degradate is considered in the drinking water assessment, because it is part of the tolerance expression. The acute and chronic surface water values (1.86 ppb and 0.41 ppb) were incorporated directly into these dietary assessments under the DEEM-FCID food categories “water, direct, all sources” and “water, indirect, all sources.”  The model and its description are available at the EPA internet site:   HYPERLINK "http://www.epa.gov/oppefed1/models/water/"  http://www.epa.gov/oppefed1/models/water/ .

Surface Water:  Tier 1 GENEEC screening model, representing a worst-case runoff scenario for pesticides in surface water, was used to estimate the upper-bound concentrations in surface water.  Total coumaphos (coumaphos + coumaphoxon) acute and chronic estimated environmental concentrations in drinking water derived from surface water sources are not likely to exceed 1.86 ppb and 0.41 ppb, respectively.

Ground Water: A Tier 1 screening model, SCI-GROW, was used to estimate total coumaphos concentrations in ground water.  This is an empirical model based on field data from prospective ground water studies.  Estimated environmental concentration of total coumaphos, representing acute and chronic exposures to ground water, is 0.17 ppb.  Ground water sources were not included in this assessment, as the estimated environmental concentration for this water source is minimal in comparison to surface water.

The recommended application rate for coumaphos spent solution from dip vat operations on non-agricultural land is 10,000 liters (L) of coumaphos spent solution containing 10 ppb spread over a one-acre field.  A conversion efficiency of coumaphos to coumaphoxon of 10.2% was derived from available (supplemental) data on photodegradation in water.  This conversion efficiency was used to estimate a coumaphoxon application rate of 0.02 lbs ai/A.

DEEM-FCID™ Program and Consumption Information

Coumaphos acute and chronic dietary exposure assessments were conducted using the Dietary Exposure Evaluation Model software with the Food Commodity Intake Database DEEM-FCID™,Version 2.03 which incorporates consumption data from USDA’s Continuing Surveys of Food Intakes by Individuals (CSFII), 1994-1996 and 1998.  The 1994-96, 98 data are based on the reported consumption of more than 20,000 individuals over two non-consecutive survey days.  Foods “as consumed” (e.g., apple pie) are linked to EPA-defined food commodities (e.g. apples, peeled fruit - cooked; fresh or N/S; baked; or wheat flour - cooked; fresh or N/S, baked) using publicly available recipe translation files developed jointly by USDA/ARS and EPA.  For chronic exposure assessment, consumption data are averaged for the entire U.S. population and within population subgroups, but for acute exposure assessment are retained as individual consumption events.  Based on analysis of the 1994-96, 98 CSFII consumption data, which took into account dietary patterns and survey respondents, HED concluded that it is most appropriate to report risk for the following population subgroups: the general U.S. population, all infants (<1 year old), children 1-2, children 3-5, children 6-12, youth 13-19, adults 20-49, females 13-49, and adults 50+ years old.

For chronic dietary exposure assessment, an estimate of the residue level in each food or food-form (e.g., orange or orange juice) on the food commodity residue list is multiplied by the average daily consumption estimate for that food/food form to produce a residue intake estimate.  The resulting residue intake estimate for each food/food form is summed with the residue intake estimates for all other food/food forms on the commodity residue list to arrive at the total average estimated exposure.  Exposure is expressed in mg/kg body weight/day and as a percent of the cPAD.  This procedure is performed for each population subgroup.

For acute exposure assessments, individual one-day food consumption data are used on an individual-by-individual basis.  The reported consumption amounts of each food item can be multiplied by a residue point estimate and summed to obtain a total daily pesticide exposure for a deterministic exposure assessment, or “matched” in multiple random pairings with residue values and then summed in a probabilistic assessment.  The resulting distribution of exposures is expressed as a percentage of the aPAD on both a user (i.e., only those who reported eating relevant commodities/food forms) and a per-capita (i.e., those who reported eating the relevant commodities as well as those who did not) basis.  In accordance with HED policy, per capita exposure and risk are reported for all tiers of analysis.  However, for tiers 1 and 2, any significant differences in user vs. per capita exposure and risk are specifically identified and noted in the risk assessment.

V. Toxicological Information

The acute dietary endpoint for the general population is based on plasma, erythrocyte and brain ChE inhibition (measured at time of peak inhibition) in PND 11 rats following a single oral dose in the comparative cholinesterase study.  This endpoint, selected by the coumaphos risk assessment team (Dec 2006), is considered appropriate for the general population because the effects were observed following a single dose, and the route of administration (oral) is appropriate for dietary considerations.  Previously, the acute dietary endpoint was based on plasma and erythrocyte ChE inhibition observed in rats at a LOAEL of 2 mg/kg (no NOAEL was observed) in an acute neurotoxicity study.  The newly selected endpoint is protective of this effect, as well as all others seen in the mammalian toxicology database attributable to a single dose.

A separate acute dietary endpoint for female ages 13-49 years was not selected because coumaphos does not induce any effects attributable to a single dose, including developmental effects that would affect this population subgroup.

The chronic dietary endpoint, previously selected by the HED HIARC, is based on plasma and RBC ChE inhibition in males and females in the chronic toxicity study in dogs.  This endpoint is considered appropriate for chronic dietary exposure due to the oral route of administration and the chronic duration of exposure.  The study and endpoint were selected because they are protective of effects observed in all the other available studies, including offspring effects seen in the recently submitted developmental neurotoxicity study.

 A summary of the toxicological doses and endpoints selected for the dietary exposure assessments is provided in Table 2.

VI. Results/Discussion

As stated above, for acute and chronic assessments, HED is concerned when dietary risk exceeds 100% of the PAD.  The DEEM-FCID™ analyses estimate the dietary exposure of the U.S. population and various population subgroups.  The results reported in Tables 3 and 4 are for the general U.S. Population, all infants (<1 year old), children 1-2, children 3-5, children 6-12, youth 13-19, females 13-49, adults 20-49, and adults 50+ years.  Cancer risk is determined for the general U.S. population only.

Results of Acute Dietary (Food and Drinking Water) Exposure Analysis

The acute aggregate dietary exposure estimates are below HED’s level of concern (<100 % aPAD) for the U.S. population and all population subgroups.  Combined dietary exposure from food and drinking water at the 99.9th percentile of exposure is 15% of the aPAD for the U.S. population and 38% of the aPAD for all infants (<1 yr), the most highly exposed population subgroup. The acute aggregate dietary exposure results are shown in Tables 3 and 4.

Results of Chronic Dietary (Food and Drinking Water) Exposure Analysis

The chronic aggregate dietary exposure estimates are below HED’s level of concern (< 100% of the cPAD) for the U.S. population and all population subgroups. Combined dietary exposure from food and drinking water is 6% of cPAD for the U.S. population and 13% of the cPAD for all infants (<1 yr), the most highly exposed population subgroup. The chronic aggregate dietary exposure results are shown in Table 4.

VII.	Characterization of Inputs/Outputs

In the course of conducting a refined dietary exposure analysis, decisions are made regarding the following:  the residue data used in the analysis (e.g., field trials, monitoring data, etc.), refinements incorporated in the analysis (such as percent crop treated and processing factors).

Coumaphos is an organophosphate insecticide/aracicide currently used for the control of mites and insects on livestock. The assessment for food incorporates refined anticipated residue estimates for livestock commodities that were derived from PDP monitoring (coumaphos and coumaphos oxygen analog). Refinements to percent livestock treated information were not necessary because risk estimates assuming 100% crop treated were below HED’s level of concern.

Total coumaphos (coumaphos + coumaphoxon) acute and chronic estimated environmental concentrations in drinking water were derived from surface water sources. HED believes the environmental concentrations (EECs) are still conservative estimates because most of the coumaphos spent solution resulting from the dip use on livestock is collected and transported to concrete-lined evaporation pits, thereby negating any potential for groundwater contamination.

VIII.	Conclusions

Acute and chronic aggregate dietary (food and drinking water) exposure and risk assessments were conducted using the Dietary Exposure Evaluation Model DEEM-FCID™, Version 2.03 which use food consumption data from the U.S. Department of Agriculture’s Continuing Surveys of Food Intakes by Individuals (CSFII) from 1994-1996 and 1998.  These dietary exposure and risk assessments for coumaphos include the following: (1) Section 3 requests for coumaphos in honey; (2) new acute toxicological endpoint; (3) and the latest monitoring data for beef and milk.

The partially refined acute and chronic aggregate dietary exposure estimates for coumaphos are below HED’s level of concern for the general U.S. population and all population subgroups.

DEPARTMENT OF TRANSPORTATION

Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2021-0451; Project Identifier AD-2021-00007-T]
RIN 2120-AA64

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD)
2019-01-08, which applies to certain The Boeing Company Model 777-200,
-200LR, -300, and -300ER series airplanes. AD 2019-01-08 requires
modifications for galley mounted attendant seat fittings. Since the FAA
issued AD 2019-01-08, the FAA determined that additional airplanes are
subject to the unsafe condition. This proposed AD would retain the
requirements of AD 2019-01-18 and expand the applicability to include
additional airplanes. The FAA is proposing this AD to address the
unsafe condition on these products.

DATES: The FAA must receive comments on this proposed AD August 9,
2021.

ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:

the proposal because of those comments.
    Except for Confidential Business Information (CBI) as described in
the following paragraph, and other information as described in 14 CFR
11.35, the FAA will post all comments received, without change, to
https://www.regulations.gov, including any personal information you
provide. The agency will also post a report summarizing each
substantive verbal contact received about this proposed AD.

Confidential Business Information

    CBI is commercial or financial information that is both customarily
and actually treated as private by its owner. Under the Freedom of
Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public
disclosure. If your comments responsive to this NPRM contain commercial
or financial information that is customarily treated as private, that
you actually treat as private, and that is relevant or responsive to
this NPRM, it is important that you clearly designate the submitted
comments as CBI. Please mark each page of your submission containing
CBI as ``PROPIN.'' The FAA will treat such marked submissions as
confidential under the FOIA, and they will not be placed in the public
docket of this NPRM. Submissions containing CBI should be sent to
Brandon Lucero, Aerospace Engineer, Cabin Safety and Environmental
Systems Section, FAA, Seattle ACO Branch, 2200 South 216th St., Des
Moines, WA 98198; phone and fax:<PHONE_NUMBER>; email:
<EMAIL_ADDRESS>Any commentary that the FAA receives which is
not specifically designated as CBI will be placed in the public docket
for this rulemaking.

Background

    The FAA issued AD 2019-01-08, Amendment 39-19547 (84 FR 4318,

February 15, 2019) (AD 2019-01-08), for certain The Boeing Company
Model 777-200, -200LR, -300, and -300ER series airplanes. AD 2019-01-08
was prompted by a report that showed non-compliance exists on some in-
service galley mounted attendant seat fitting installations. AD 2019-
01-08 requires modifications for galley mounted attendant seat
fittings. The agency issued AD 2019-01-08 to address non-compliant
flight attendant seats, which could fail in a high-G crash and result
in potential injury to flight attendants and consequent inability of
the flight attendants to assist with passenger evacuation in a timely
manner.

Actions Since AD 2019-01-08 Was Issued

    Since the FAA issued AD 2019-01-08, an operator reported that line
numbers (L/Ns) 413, 421, 424, 425, 426, and 439, which are equipped
with galley part number (P/N) 1013G42A00000 (one of the affected part
numbers identified in Boeing Special Attention Service Bulletin 777-25-
0649, Revision 1, dated October 6, 2017) were not included in AD 2019-
01-08. A subsequent investigation by Boeing determined that L/Ns 1111,
1115, and 1137 were also missing from the effectivity of Boeing Special
Attention Service Bulletin 777-25-0649, Revision 1, dated October 6,
2017, and therefore not included in the applicability of AD 2019-01-08.

FAA's Determination

    The FAA is issuing this NPRM after determining that the unsafe
condition described previously is likely to exist or develop on other
products of the same type design.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Boeing Special Attention Service Bulletin 777-25-
0649, Revision 2, dated October 8, 2020. This service information
specifies procedures for modifying galley mounted attendant seat
fittings. 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.

Proposed AD Requirements in This NPRM

    Although this proposed AD does not explicitly restate the
requirements of AD 2019-01-08, this proposed AD would retain all of the
requirements of AD 2019-01-08. Those requirements are referenced in the
service information identified previously, which, in turn, is
referenced in paragraph (g) of this proposed AD. This proposed AD would
add airplanes to the applicability. This proposed AD would also require
accomplishment of the actions identified as ``RC'' (required for
compliance) in the Accomplishment Instructions of Boeing Special
Attention Service Bulletin 777-25-0649, Revision 2, dated October 8,
2020, described previously.
    For information on the procedures and compliance times, see this
service information at https://www.regulations.gov by searching for and
locating Docket No. FAA-2021-0451.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would
affect 50 airplanes of U.S. registry. The FAA estimates the following
costs to comply with this proposed AD:

                                                 Estimated Costs

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

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.
    The FAA is 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

    The FAA determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 the proposed
regulation:
    (1) Is not a ``significant regulatory action'' under Executive
Order 12866,
    (2) Would not affect intrastate aviation in Alaska, and
    (3) Would not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.

Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by:
0
a. Removing Airworthiness Directive 2019-01-08, Amendment 39-19547 (84
FR 4318, February 15, 2019), and
0
b. Adding the following new airworthiness directive:

The Boeing Company: Docket No. FAA-2021-0451; Project Identifier AD-
2021-00007-T.

(a) Comments Due Date

    The FAA must receive comments on this airworthiness directive
(AD) action by August 9, 2021.

(b) Affected ADs

    This AD replaces AD 2019-01-08, Amendment 39-19547 (84 FR 4318,
February 15, 2019) (AD 2019-01-08).

(c) Applicability

    This AD applies to The Boeing Company Model 777-200, -200LR, -
300, and -300ER series airplanes, certificated in any category, as
identified in Boeing Special Attention Service Bulletin 777-25-0649,
Revision 2, dated October 8, 2020.

(d) Subject

    Air Transport Association (ATA) of America Code 25, Equipment/
furnishings.

(e) Unsafe Condition

    This AD was prompted by a report that showed a non-compliance
exists on some in-service galley attendant seat fitting
installations, and a determination that additional airplanes are
subject to the unsafe condition. The FAA is issuing this AD to
address non-compliant flight attendant seats, which could fail in a
high-G crash and result in potential injury to flight attendants and
consequent inability of the flight attendants to assist with
passenger evacuation in a timely manner.

(f) Compliance

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

(g) Required Actions

    Except as specified by paragraph (h) of this AD: At the
applicable times specified in paragraph 1.E., ``Compliance,'' of
Boeing Special Attention Service Bulletin 777-25-0649, Revision 2,
dated October 8, 2020, do all applicable actions identified as
``RC'' (required for compliance) in, and in accordance with, the
Accomplishment Instructions of Boeing Special Attention Service
Bulletin 777-25-0649, Revision 2, dated October 8, 2020.

(h) Exception to Service Information Specifications

    Where Boeing Special Attention Service Bulletin 777-25-0649,
Revision 2, dated October 8, 2020, uses the phrase ``the Revision 2
date of this service bulletin,'' this AD requires using ``the
effective date of this AD.''

(i) No Reporting Requirement

    Although the service information referenced in Boeing Special
Attention Service Bulletin 777-25-0649, Revision 2, dated October 8,
2020, specifies to submit certain information to the manufacturer,
this AD does not include that requirement.

(j) Credit for Previous Actions

    This paragraph provides credit for the actions specified in
paragraph (g) of this AD, if those actions were performed before the
effective date of this AD using Boeing Special Attention Service
Bulletin 777-25-0649, Revision 1, dated October 6, 2017 (which is
incorporated by reference in AD 2019-01-08).

(k) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Seattle ACO Branch, 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 responsible Flight Standards Office,
as appropriate. If sending information directly to the manager of
the certification office, send it to the attention of the person
identified in Related Information. 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 responsible Flight Standards 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 Company Organization Designation
Authorization (ODA) that has been authorized by the Manager, Seattle
ACO Branch, FAA, 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) AMOCs approved for AD 2019-01-08 are approved as AMOCs for
the corresponding provisions of Boeing Special Attention Service
Bulletin 777-25-0649, Revision 2, dated October 8, 2020, that are
required by paragraph (g) of this AD.
    (5) For service information that contains steps that are labeled
as Required for Compliance (RC), the provisions of paragraphs
(k)(5)(i) and (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.

ENVIRONMENTAL PROTECTION AGENCY

[EPA-HQ-OPP-2020-0060; FRL-10021-91]

Cancellation Order for Certain Pesticide Registration and
Amendments To Terminate Uses

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

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

SUMMARY: This notice announces EPA's order for the cancellations and
amendments to terminate uses, voluntarily requested by the registrants
and accepted by the Agency, of the products listed in Table 1 and Table
2 of Unit II, pursuant to the Federal Insecticide, Fungicide, and
Rodenticide Act (FIFRA). This cancellation order follows a February 10,
2021 Federal Register Notice of Receipt of Requests from the
registrants listed in Table 3 of Unit II to voluntarily cancel and
amend to terminate uses of these product registrations. In the February
10, 2021 notice, EPA indicated that it would issue an order
implementing the cancellations and amendments to terminate uses, unless
the Agency received substantive comments within the 30-day comment
period that would merit its further review of these requests, or unless
the registrants withdrew their requests. The Agency received three
comments on the notice, but none merited its further review of the
requests. Further, the registrants did not withdraw their requests.
Accordingly, EPA hereby issues in this notice a cancellation order
granting the requested cancellations and amendments to terminate uses.
Any distribution, sale, or use of the products subject to this

III. Summary of Public Comments Received and Agency Response to
Comments

    The Agency received one anonymous public comment and two other
public comments on the notice. For these reasons, the Agency does not
believe that the comments submitted during the comment period merit
further review or a denial of the requests for voluntary cancellation
and use termination.

IV. Cancellation Order

    Pursuant to FIFRA section 6(f) (7 U.S.C. 136d(f)(1)), EPA hereby
approves the requested cancellations and amendments to terminate uses
of the registrations identified in Tables 1 and 2 of Unit II.
Accordingly, the Agency hereby orders that the product registrations
identified in Tables 1 and 2 of Unit II are canceled and amended to
terminate the affected uses. The effective date of the cancellations
that are subject of this notice is April 2, 2021. Any distribution,
sale, or use of existing stocks of the products identified in Tables 1
and 2 of Unit II in a manner inconsistent with any of the provisions
for disposition of existing stocks set forth in Unit VI will be a
violation of FIFRA.

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

    Section 6(f)(1) of FIFRA (7 U.S.C. 136d(f)(1)) provides that a
registrant of a pesticide product may at any time request that any of
its pesticide registrations be canceled or amended to terminate one or
more uses. FIFRA further provides that, before acting on the request,
EPA must publish a notice of receipt of any such request in the Federal
Register. Thereafter, following the public comment period, the EPA
Administrator may approve such a request. The notice of receipt for
this action was published for comment in the Federal Register of
February 10, 2021 (86 FR 8902) (FRL-10016-15). The comment period
closed on March 12, 2021.

VI. Provisions for Disposition of Existing Stocks

    Existing stocks are those stocks of registered pesticide products
which are currently in the United States and which were packaged,
labeled, and released for shipment prior to the effective date of the
action. The existing stocks provision for the products subject to this
order is as follows.
    For the voluntary cancellations listed in Table 1 of Unit II, the
registrants may continue to sell and distribute existing stocks of
products listed in Table 1 until March 31, 2022, which is 1 year after
publication of this cancellation order in the Federal Register.
Thereafter, the registrants are prohibited from selling or distributing
products listed in Table 1 of Unit II, except for export in accordance
with FIFRA section 17 (7 U.S.C. 136o) or for proper disposal.
    Now that EPA has approved the product labels reflecting the
requested amendments to terminate, listed in Table 2 of Unit II,
registrants are permitted to sell or distribute products listed in
Table 2 of Unit II under the previously approved labeling until
September 30, 2022, a period of 18 months after publication of the
cancellation order in this Federal Register, unless other restrictions
have been imposed. Thereafter, registrants will be prohibited from
selling or distributing the products whose labels include the
terminated uses identified in Table 2 of Unit II, except for export
consistent with FIFRA section 17 or for proper disposal.
    Persons other than the registrant may sell, distribute, or use
existing stocks of canceled products and products whose labels include
the terminated uses until supplies are exhausted, provided that such
sale, distribution, or use is consistent with the terms of the
previously approved labeling on, or that accompanied, the canceled
products and terminated uses.
