MEMORANDUM

To: Halogenated Solvent Docket #  EPA-HQ-OAR-2002-0009

From: Elaine Manning, EPA

Date: October 3, 2008

Re: Reassessment of Non-cancer Hazard Associated with TCE to Support the
Halogenated Solvent Cleaning Rule

This memorandum presents a brief overview of the reassessment of chronic
non-cancer hazard conducted to support the Halogenated Solvent Cleaning
rule.  Non-cancer risks for the 1,080 halogenated solvent cleaning
facilities included in the 2002 National Emissions Inventory (NEI) were
recalculated using an air criterion for trichloroethylene (TCE) obtained
from the New York State Department of Health (NYS DOH, 2006).  A
Microsoft Excel workbook was provided to EPA on September 29, 2008 and
provided a summary of the recalculated chronic non-cancer hazard
estimates.  This memo serves as additional documentation to the
reanalysis.

For the risk assessment for the Halogenated Solvent Cleaning rule
completed in August 2006, the maximum hazard index (HI) was 0.2, and
there were no facilities with an HI greater than 1.  The highest
facility HI of 0.2 was associated with 1,1,1-trichloroethane (TCA).

The 2006 risk assessment used a chronic California EPA (CalEPA)
inhalation reference exposure level (REL) for TCE of 600 µg/m3 as the
chronic RfC.  This CalEPA inhalation REL is based on a 1973 study of 19
workers who experienced symptoms of drowsiness, fatigue, headache, and
eye irritation associated with TCE.  CalEPA identified the use of human
exposure data from workers exposed over a period of years as a strength
of the REL; however, the lack of reproductive and developmental toxicity
studies and the lack of a no effect level were identified as major areas
of uncertainty.

Since promulgation of the Halogenated Solvent Cleaning rule, EPA became
aware of a newer assessment for non-cancer effects of TCE developed by
the NYS DOH.  The NYS DOH states that their air criterion for TCE of 10
µg/m3 based on central nervous system effects, is essentially
equivalent to a United States Environmental Protection Agency’s
chronic reference concentration (RfC) or an Agency for Toxic Substances
and Disease Registry’s chronic minimal risk level (MRL).  In addition
to evaluating a number of studies which look at numerous different
toxicological endpoints, the NYS DOH air criterion relies on a 1993
study which evaluated clinical neurological effects (as measured by
coordination tests) in 99 Danish workers.  For 70 of these workers, the
dominant exposure was TCE, while for 25 of the workers the dominant
exposure was to CFC 113.  Air exposures were extrapolated from
measurements of the urinary metabolite TCA.  Limitations of this study
include some uncertainty about the actual long term exposure levels of
the workers to TCE during their employment, and that 25 of the 99
subjects were exposed primarily to CFC 113.   The NYS DOH assessment is
limited by gaps in the data on developmental effects and immunotoxicity,
and concerns about adequacy of methods for evaluating health risks to
children (limitations it shares with the CalEPA assessment).

In September 2008, EPA reassessed non-cancer hazard for all facilities
based on the use of the NY air criterion for TCE of 10 µg/m3.  Using
emissions data from EPA’s 2002 NEI database and the Human Exposure
Model (HEM-Screen), human health non-cancer hazards were recalculated
using the new value.  As might be expected, the HIs increased for the
662 (376 scaled-up) total facilities that emit TCE.  There were 10
facilities (6 scaled-up) estimated to have chronic non-cancer HIs
greater than 1.  The maximum HI was estimated to be 7.  A comparison of
results for these facilities may be found in Table 1.

Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede Airworthiness Directive (AD) 2013-13-
16, which applies to all Airbus Model A330-200, A330-200 Freighter,
A330-300 series airplanes, and all Airbus Model A340-200, -300, -500,
and -600 series airplanes. AD 2013-13-16 currently requires repetitive
inspections for discrepancies of the ball-screw assembly of the
trimmable horizontal stabilizer actuator (THSA), repetitive greasing of
the THSA ball-nut, and replacement of the THSA if necessary; and
modification or replacement (as applicable) of the ball-nut assembly,

which ends certain repetitive inspections. Since we issued AD 2013-13-
16, we have determined that a modification that automatically detects
failure of the ball-screw assembly is necessary. This proposed AD would
require an inspection, corrective actions if necessary, lubrication of
the ball-nut, modification of the THSA, and removal of certain
airplanes from the applicability. We are proposing this AD to address
the unsafe condition on these products.

DATES: We must receive comments on this proposed AD by February 2,
2017.

Discussion

    On June 21, 2013, we issued AD 2013-13-16, Amendment 39-17504 (78
FR 47537, August 6, 2013) (``AD 2013-13-16''). AD 2013-13-16 requires
actions intended to address an unsafe condition on all Airbus Model
A330-200, A330-200 Freighter, and A330-300 series airplanes, and all
Airbus Model A340-200, -300, -500, and -600 series airplanes.
    Since we issued AD 2013-13-16, Airbus transferred most of the
requirements of AD 2013-13-16 into airworthiness limitations, except
the requirements for ECAM fault messages.
    The European Aviation Safety Agency (EASA) which is the Technical
Agent for the Member States of the European Union, has issued EASA
Airworthiness Directive 2014-0219, dated September 29, 2014 (referred
to after this as the Mandatory Continuing Airworthiness Information, or
``the MCAI''), to correct an unsafe condition on all Airbus Model A330
and Model A340 series airplanes. The MCAI states:

    Several cases of transfer tube disconnection from the ball-nut
of the trimmable horizontal stabilizer actuator (THSA) part number
(P/N) 47172 and 47147-400 were detected on the ground during
greasing and maintenance. Investigation results showed that this was
caused by water ingress into the ball-nut, resulting in the jamming
of the ball transfer circuit when the water froze. If the three
(independent) ball circuits fail, then the THSA operates on a fail-
safe nut (which operates without balls), which jams after several
movements on the ball-screw of the THSA.
    This condition, if not detected and corrected, could damage the
ball-screw and the fail-safe nut, possibly resulting in jamming of
the THSA and consequent reduced control of the aeroplane.
    To detect at an early stage any distortion or initiation of
disconnection, [Directorate General for Civil Aviation] DGAC France
issued AD 2001-356 and AD 2001-357 to require repetitive inspections
of the transfer tubes and their collars and, depending on findings,
corrective action(s).
    Prompted by another case of transfer tube disconnection, DGAC
France issued AD 2001-356R2 and AD 2001-357R2 to require additional
repetitive greasing and reinforcement of the ball-nut maintenance
greasing instructions.
    Subsequently, DGAC France issued AD 2002-037 and AD 2002-038 to
require a modification that was also terminating action for the
repetitive inspections and greasing tasks required by DGAC France AD
2001-356R2 and AD 2001-357R2 for the THSA P/N 47172 by application
of Service Bulletin (SB) A330-27-3085 or SB A340-27-4089 (equivalent
to Airbus production modification 49590), as applicable, changing
the THSA P/N from 47172 to 47172-300.
    Later on, DGAC France issued AD 2002-414 (later revised to R3)
and AD 2002-415 (later revised to R2), which superseded the DGAC
France AD 2001-356R2, AD 2001-357R2, AD 2002-037, and AD 2002-038,
requiring:

--Repetitive inspections of all THSA P/N in service,
--repetitive lubrication of some THSA P/N, and
--replacement of THSA P/N 47172, 47147-400 and 47147-2XX/-3XX.

    In addition, the electrical flight control computers monitor the
operation of the THSA and the jamming of this actuator could be
detected and indicated by messages on the maintenance system and on
the [electronic centralized aircraft monitor] ECAM. For that reason,
DGAC France AD 2002-414 and AD 2002-415 also required inspection of
the THSA after display of such message(s).
    After those [DGAC France] ADs were issued, Airbus introduced 4
new THSA, P/N 47172-500, P/N 47172-510, P/N 47172-520 and P/N 47172-
530.
    As these new THSA also needed to be inspected/lubricated, EASA
issued [EASA] AD 2010-0192 and [EASA] AD 2010-0193, which retained
the requirements of DGAC France AD F-2002-414R3 and AD F-2002-415R2
respectively, which were superseded, to add required repetitive
inspections and lubrications of the new THSA P/N.
    Since those [EASA] ADs were issued, all requirements of EASA AD
2010-0192 and AD 2010-0193 were transferred into Airbus
Airworthiness Limitations Section (ALS) Part 4, except the
requirement of paragraph (2.3) of those [EASA] ADs. At this time,
compliance with ALS Part 4 tasks is required by EASA AD 2013-0268
(A330 aeroplanes) and [EASA] AD 2013-0269 (A340 aeroplanes),
respectively [which correspond to FAA AD 2015-16-02, Amendment 39-
18227 (80 FR 48019, August 11, 2015); and AD 2014-23-17, Amendment
39-18033 (79 FR 71304, December 2, 2014) (A340 airplanes);
respectively.]

    In addition, Airbus developed a Checkable Shear Pin (CSP) for
the THSA and an associated additional electrical harness, which
consists of installation of two Electrical Detection Devices (EDD)
on the lower attachment secondary load path, which gives an
indication to the Flight Control Primary Computers of secondary load
path engagement.
    After embodiment of these modifications on an aeroplane, the
repetitive inspections of the ball-screw assembly for integrity of
the primary and secondary load paths is no longer required, because
the failure is detected automatically by this new device.
    For the reasons described above, this [EASA] AD retains only the
requirement of paragraph (2.3) of EASA AD 2010-0192 and 2010-0193
[actions following ECAM fault messages], which are superseded, and
requires the installation of CSP and associated additional
electrical harness on the THSA of the aeroplane. This [EASA] AD also
requires, for A340-500/-600 aeroplanes that are post-SB A340-92-5008
(at Revision 06 or earlier), accomplishment of A340 ALS Part 3 task
274000-B0002-1-C, providing a grace period of 3 months for
aeroplanes that have exceeded the applicable threshold or interval.

    The unsafe condition is the degraded operation of the THSA, which
could result in reduced control of the airplane.
    Model A330-223F and A330-243F airplanes have been removed from the
applicability of this proposed AD to correspond with the MCAI.
    Required actions include a detailed inspection and corrective
actions if an ECAM fault message is displayed, repetitive lubrication
of the THSA ball-nut, and a modification of the THSA by installing a
CSP and associated electrical harness.
    Required actions also include certain ``Additional Work'' that is
described in the following service information.
     ``Additional Work'' in Airbus Service Bulletin A330-27-
3143, Revision 01, dated July 10, 2012, is described as removing the
closing plug from the electrical harness 4515VB and connecting the
electrical harness 4515VB to the THSA.
     ``Additional Work'' in Airbus Service Bulletin A330-92-
3046, Revision 06, dated November 15, 2013; and Airbus Service Bulletin
A340-92-4056, Revision 04, dated December 5, 2013; is described as
replacement of a certain harness item, installation of placards and
cable support, modification of a certain bracket, and installation of a
certain spacer.
     ``Additional Work'' in Airbus Service Bulletin A340-92-
5008, Revision 07, dated February 8, 2013, is described as replacing a
certain wiring harness, replacing a certain THSA harness, installing
additional placards, and modifying a certain wire harness installation
order.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to our bilateral agreement with the State of Design Authority, we have
been notified of the unsafe condition described in the MCAI and service
information referenced above. We are proposing this AD because we
evaluated all pertinent information and determined an unsafe condition
exists and is likely to exist or develop on other products of the same
type design.

Explanation of Proposed Compliance Times

    The MCAI requires operators to modify certain airplanes by
installing a CSP by a certain date. In order to provide operators with
sufficient time to accomplish the modification, we have determined that
a 12-month period from the effective date of this AD is acceptable.
This difference had been coordinated with the EASA.

Costs of Compliance

    We estimate that this proposed AD affects 33 airplanes of U.S.
registry.
    The actions required by AD 2013-13-16, and retained in this
proposed AD take about 1 work-hour per product, at an average labor
rate of $85 per work-hour. Based on these figures, the estimated cost
of the actions that are required by AD 2013-13-16 is $85 per product.
    We also estimate that it would take about 67 work-hours per product
to comply with the basic requirements of this proposed AD. The average
labor rate is $85 per work-hour. Required parts would cost about
$14,198 per product. Based on these figures, we estimate the cost of
this proposed AD on U.S. operators to be $656,469, or $19,893 per
product.

Authority for This Rulemaking

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

Regulatory Findings

    We determined that this 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 this proposed
regulation:
    1. Is not a ``significant regulatory action'' under Executive Order
12866;
    2. Is not a ``significant rule'' under the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979);
    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.

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:

PART 39--AIRWORTHINESS DIRECTIVES

0
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 removing Airworthiness Directive (AD)
2013-13-16, Amendment 39-17504 (78 FR 47537, August 6, 2013), and
adding the following new AD:

Airbus: Docket No. FAA-2016-9393; Directorate Identifier 2014-NM-
199-AD.

(a) Comments Due Date

    We must receive comments by February 2, 2017.

(b) Affected ADs

    This AD replaces AD 2013-13-16, Amendment 39-17504 (78 FR 47537,
August 6, 2013) (``AD 2013-13-16'').

(c) Applicability

    This AD applies to the airplanes identified in paragraphs (c)(1)
and (c)(2) of this AD, certificated in any category.
    (1) Airbus Model A330-201, -202, -203, -223, -243, -301, -302, -

and -642 airplanes, all manufacturer serial numbers.

(d) Subject

    Air Transport Association (ATA) of America Code 27, Flight
Controls.

(e) Reason

    This AD was prompted by the determination that a modification
that automatically detects failure of the ball-screw assembly is
necessary. We are issuing this AD to detect and correct wear on the
trimmable horizontal stabilizer actuator (THSA), possibly resulting
in damage to the ball-screw and fail-safe nut, which could jam the
THSA and result in reduced control of the airplane.

(f) Compliance

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

(g) Actions for Electronic Centralized Aircraft Monitor (ECAM) Fault
Messages

    For airplanes other than those identified in figure 1 to

of the ``PRIM X PITCH FAULT'' or ``STAB CTL FAULT'' messages is
displayed on the ECAM associated with the ``PITCH TRIM ACTR (1CS)''
maintenance message, before further flight after each time the
message is displayed on the ECAM, do the actions specified in
paragraphs (g)(1) and (g)(2) of this AD.
    (1) Do the applicable detailed inspection of the ball-screw
assembly for integrity of the primary and secondary load path; check
the checkable shear pins (CSP), if installed; and do all applicable
corrective actions; as specified in paragraph (g)(1)(i), (g)(1)(ii),
or (g)(1)(iii) of this AD. Do all applicable corrective actions
before further flight.

ENVIRONMENTAL PROTECTION AGENCY

[EPA-HQ-OAR-2018-0118; FRL-9978-96-OAR]

Proposed Agency Information Collection Request; Comment Request;
Servicing of Motor Vehicle Air Conditioners (Renewal)

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

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

SUMMARY: The Environmental Protection Agency is planning to submit an
information collection request (ICR), ``Servicing of Motor Vehicle Air
Conditioners (Renewal)'' (EPA ICR No. 1617.09, OMB Control No. 2060-
0247) to the Office of Management and Budget (OMB) for review and
approval in accordance with the Paperwork Reduction Act. Before doing
so, EPA is soliciting public comments on specific aspects of the
proposed information collection as described below. This is a proposed
extension of the ICR, which is currently approved through December 31,
2018. An Agency may not conduct or sponsor and a person is not required
to respond to a collection of information unless it displays a
currently valid OMB control number.

DATES: Comments must be submitted on or before August 6, 2018.

ADDRESSES: Submit your comments, referencing Docket ID No. EPA-HQ-OAR-
2018-0118, online using www.regulations.gov (our preferred method), by
email to [email protected], or by mail to: EPA Docket Center,
Environmental Protection Agency, Mail Code 28221T, 1200 Pennsylvania
Ave. NW, Washington, DC 20460.
    EPA's policy is that all comments received will be included in the
public docket without change including any personal information
provided, unless the comment includes profanity, threats, information
claimed to be Confidential Business Information (CBI) or other
information whose disclosure is restricted by statute.

FOR FURTHER INFORMATION CONTACT: Christina Thompson, Stratospheric
Protection Division, Office of Atmospheric Programs (Mail Code 6205T),
Environmental Protection Agency, 1200 Pennsylvania Ave. NW, Washington,
DC 20460; telephone number:<PHONE_NUMBER>; fax number:<PHONE_NUMBER>;
email address: [email protected].

SUPPLEMENTARY INFORMATION: Supporting documents which explain in detail
the information that the EPA will be collecting are available in the
public docket for this ICR. The docket can be viewed online at
www.regulations.gov or in person at the EPA Docket Center, WJC West,
Room 3334, 1301 Constitution Ave. NW, Washington, DC. The telephone
number for the Docket Center is<PHONE_NUMBER>. For additional
information about EPA's public docket, visit http://www.epa.gov/dockets.
    Pursuant to section 3506(c)(2)(A) of the PRA, EPA is soliciting
comments and information to enable it to: (i) Evaluate whether the
proposed collection of information is necessary for the proper
performance of the functions of the Agency, including whether the
information will have practical utility; (ii) evaluate the accuracy of
the Agency's estimate of the burden of the proposed collection of
information, including the validity of the methodology and assumptions
used; (iii) enhance the quality, utility, and clarity of the
information to be collected; and (iv) minimize the burden of the
collection of information on those who are to respond, including
through the use of appropriate automated electronic, mechanical, or
other technological collection techniques or other forms of information
technology, e.g., permitting electronic submission of responses. EPA
will consider the comments received and amend the ICR as appropriate.
The final ICR package will then be submitted to OMB for review and
approval. At that time, EPA will issue another Federal Register notice
to announce the submission of the ICR to OMB and the opportunity to
submit additional comments to OMB.
    Abstract: Section 609 of the Clean Air Act Amendments of 1990 (Act)
provides general guidelines for the servicing of motor vehicle air
conditioners (MVACs). It states that ``no person repairing or servicing
motor vehicles for consideration may perform any service on a motor
vehicle air conditioner involving the refrigerant for such air
conditioner without properly using approved refrigerant recycling
equipment and no such person may perform such service unless such
person has been properly trained and certified.'' In 1992, EPA
developed regulations under section 609 that were published in 57 FR
31240, and codified at 40 CFR Subpart B (Section 82.30 et seq.). The
information required to be collected under the section 609 regulations
is: Approved refrigerant handling equipment; approved independent
standards testing organizations; technician training and certification;
and certification, reporting and recordkeeping.
    Form Numbers: None.
    Respondents/affected entities: The following is a list of NAICS
codes for organizations potentially affected by the information
requirements covered under this ICR. It is meant to include any
establishment that may service or maintain motor vehicle air
conditioners.

4411 Automobile Dealers
4413 Automotive Parts, Accessories, and Tire Stores
44711 Gasoline Stations with Convenience Stores
8111 Automotive Repair and Maintenance
811198 All Other Automotive Repair and Maintenance

    Other affected groups include independent standards testing
organizations and organizations with technician certification programs.
    Respondent's obligation to respond: Mandatory (40 CFR 82.36, 82.38,
82.40, 82.42).
    Estimated number of respondents: 45,902 (per year).
    Frequency of response: On occasion, biennially, only once.
    Total estimated burden: 4,130 hours (per year). Burden is defined
at 5 CFR 1320.03(b).
    Total estimated cost: $218,009 (per year), includes $0 annualized
capital or operation & maintenance costs.
    Changes in Estimates: There is a decrease of 34 hours in the total
estimated respondent burden compared with the ICR currently approved by

OMB. This decrease is due in part to a decrease in the number of new
technician certifications and the time allotted for maintenance of the
technician certification records. In this ICR EPA estimates the number
of new technician certifications to be 40,000 per year, a decrease from
the 50,000 estimated in the previous ICR, based on information provided
by the largest technician certification program. The maintenance of
these records is estimated to require 0.067 clerical work hours per
certification, a decrease from 0.08 hours in the previous ICR,
recognizing the move towards electronic recordkeeping which may be more
efficient. Another reason for the burden decrease is a decrease in the
market for small containers of CFC-12 refrigerant. In this ICR, EPA
estimates that the number of purchases for resale only by uncertified
purchasers of small cans will be 50% less than in the previous ICR, or
approximately 69 purchases, because EPA estimates that there has been
at least a 50% reduction in the CFC-12 vehicle fleet since 2015.
