[EPA-HQ-OW-2016-0281; FRL-9948-54-OW]

Expedited Approval of Alternative Test Procedures for the
Analysis of Contaminants Under the Safe Drinking Water Act; Analysis
and Sampling Procedures

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: This action announces the U.S. Environmental Protection
Agency's (EPA's) approval of alternative testing methods for use in
measuring the levels of contaminants in drinking water and determining
compliance with national primary drinking water regulations. The Safe
Drinking Water Act authorizes EPA to approve the use of alternative
testing methods through publication in the Federal Register. EPA is
using this streamlined authority to make 16 additional methods
available for analyzing drinking water samples. This expedited approach
provides public water systems, laboratories, and primacy agencies with
more timely access to new measurement techniques and greater
flexibility in the selection of analytical methods, thereby reducing
monitoring costs while maintaining public health protection.

DATES: This action is effective July 19, 2016.

SUPPLEMENTARY INFORMATION:

 I. General Information

A. Does this action apply to me?

    Public water systems are the regulated entities required to measure
contaminants in drinking water samples. In addition, EPA Regions as
well as states and tribal governments with authority to administer the
regulatory program for public water systems under the Safe Drinking
Water Act (SDWA) may measure contaminants in water samples. When EPA
sets a monitoring requirement in its national primary drinking water
regulations for a given contaminant, the Agency also establishes in the
regulations standardized test procedures for analysis of the
contaminant. This action makes alternative testing methods available
for particular drinking water contaminants beyond the testing methods
currently established in the regulations. EPA is providing public water
systems required to test water samples with a choice of using either a
test procedure already established in the existing regulations or an
alternative test procedure that has been approved in this action or in
prior expedited approval actions. Categories and entities that may
ultimately be affected by this action include:

II. Background

A. What is the purpose of this action?

    In this action, EPA is approving 16 analytical methods for
determining contaminant concentrations in drinking water samples
collected under SDWA. Regulated parties required to sample and monitor
may use either the testing methods already established in existing
regulations or the alternative testing methods being approved in this
action or in prior expedited approval actions. The new methods are
listed along with other methods similarly approved through previous
expedited actions in 40 CFR part 141, appendix A to subpart C and on
EPA's drinking water methods Web site at https://www.epa.gov/dwanalyticalmethods.

B. What is the basis for this action?

    When EPA determines that an alternative analytical method is
``equally effective'' (i.e., as effective as a method that has already
been promulgated in the regulations), SDWA allows EPA to approve the
use of the alternative method through publication in the Federal
Register (see Section 1401(1) of SDWA). EPA is using this streamlined
approval authority to make 16 additional methods available for
determining contaminant concentrations in drinking water samples
collected under SDWA. EPA has determined that, for each contaminant or
group of contaminants listed in Section III, the additional testing
methods being approved in this action are as effective as one or more
of the testing methods already approved in the regulations for those
contaminants. Section 1401(1) of SDWA states that the newly approved
methods ``shall be treated as an alternative for public water systems
to the quality control and testing procedures listed in the
regulation.'' Accordingly, this action makes these additional 16
analytical methods legally available as options for meeting EPA's
monitoring requirements.
    This action does not add regulatory language, but does, for
informational purposes, update an appendix to the regulations at 40 CFR
part 141 that lists all methods approved under Section 1401(1) of SDWA.
Accordingly, while this action is not a rule, it is updating CFR text
and therefore is being published in the ``Final Rules'' section of the
Federal Register.

III. Summary of Approvals

    EPA is approving 16 methods that are equally effective relative to
methods previously promulgated in the regulations. By means of this
rule, these 16 methods are added to appendix A to subpart C of 40 CFR
part 141.

A. Methods developed by Voluntary Consensus Standard Bodies (VCSB)

    ASTM International. EPA compared the most recent versions of seven
ASTM International methods to the earlier versions of those methods
that are currently approved in 40 CFR part 141. Changes between the
earlier approved version and the most recent version of each method are
summarized in Smith (2015). The revisions primarily involve editorial
changes (e.g., updated references, definitions, terminology, procedural
clarifications, and reorganization of text). The revised methods are
the same as the approved versions with respect to sample collection and
handling protocols, sample preparation, analytical methodology, and
method performance data; thus, EPA finds they are equally effective
relative to the approved methods.
    EPA is thus approving the use of the following ASTM methods for the
contaminants and their respective regulations listed in the following
table:

B. Methods Developed by Vendors

    1. Hach Method 10241--Spectrophotometric Measurement of Free
Chlorine (Cl2) in Finished Drinking Water (Hach Company
2015a). In Hach Method 10241, free chlorine is converted to
monochloramine by addition of an ammonia solution to a drinking water
sample. In the presence of a cyanoferrate catalyst, monochloramine
reacts with a substituted phenol to form an intermediate monoamine
compound. The intermediate monoamine compound couples with excess
substituted phenol to form a green indophenol compound.
Spectrophotometric measurement of absorbance at 655 nm (610 nm for
colorimeters) is directly proportional to the concentration of free
chlorine in the sample.
    The currently approved methods for free chlorine in drinking water
are listed in the tables at 40 CFR 141.74(a)(2) and 40 CFR
141.131(c)(1). One of the most widely used approved methods is Standard
Method 4500-Cl G-00 (APHA 2000a), which uses a N,N-diethyl-p-
phenylenediamine (DPD) indicator for spectrophotometric determination
of residual chlorine concentrations in drinking water. The DPD
methodology can be subject to interferences associated with the
presence of manganese, chloramines, and other oxidants. Hach Method
10241 is not subject to such interferences.
    A multi-laboratory study compared the performance characteristics
of Hach Method 10241 to the performance characteristics of the approved
Standard Method 4500-Cl G-00. A variety of samples, including drinking
water samples from both surface water and ground water sources, were
fortified with known chlorine concentrations and analyzed by each
method. The results are summarized in the validation study report (Hach
Company 2015b). EPA has determined that Hach Method 10241 is equally as
effective as the approved Standard Method 4500-Cl G-00. The basis for
this determination is discussed in Adams and Smith (2016). Therefore,
EPA is approving Hach Method 10241 for determining free chlorine
concentrations in drinking water. Hach Method 10241 can be obtained
from Hach Company, 5600 Lindbergh Drive, Loveland, Colorado 80539.
(http://www.hach.com.)
    2. Hach Method 8026--Spectrophotometric Measurement of Copper in
Finished Drinking Water (Hach Company 2015c). In Hach Method 8026,
cuprous copper is measured colorimetrically by complexation with
bicinchoninic acid. The intensity in color is proportional to the
copper concentration, and spectrophotometer measurements are taken at
560 nm. Cupric copper present in samples is chemically reduced to
cuprous copper. Metal and hardness interferences in samples are
mitigated through the use of a chelating agent. The method is performed
by the addition of

powder pillows containing reagents to the water samples.
    The currently approved methods for the analysis of copper in
drinking water are listed in the table at 40 CFR 141.23(k)(1). The
approved methods are based on atomic spectroscopy technologies. Hach
Method 8026 employs a spectrophotometer, and is based on known
complexation principles and simple color/absorbance measurements to
determine copper concentrations.
    A multi-laboratory validation study was conducted to compare the
performance of Hach Method 8026 to EPA Method 200.7 (USEPA 1994), one
of the approved methods for the analysis of copper in drinking water.
Multiple finished drinking water samples drawn from both ground water
and surface water sources were used in the validation study. Precision,
accuracy and sensitivity data were collected by analyzing drinking
water samples fortified with varying concentrations of copper
standards. The results are summarized in the validation study report
(Hach Company 2015d). EPA has determined that Hach Method 8026 is
equally as effective as the approved EPA Method 200.7. The basis for
this determination is discussed in Adams and Smith (2016). Therefore,
EPA is approving Hach Method 8026 for the analysis of copper in
drinking water. Hach Method 8026 can be obtained from Hach Company,
5600 Lindbergh Drive, Loveland, Colorado 80539. (http://www.hach.com).
    3. Hach Method 10261--Total Organic Carbon in Finished Drinking
Water by Catalyzed Ozone Hydroxyl Radical Oxidation Infrared Analysis
(Hach Company 2015e). Hach Method 10261 is a method for the
determination of total organic carbon (TOC) in drinking water using an
advanced oxidation process and non-dispersive infrared spectroscopy. In
this method, ozone and a base are added to water to produce hydroxyl
radicals. The hydroxyl radicals oxidize organic carbon to produce
carbon dioxide and sodium oxalate. The sodium oxalate is further
oxidized to carbon dioxide using acidification and a manganese
catalyst. The carbon dioxide produced by both oxidation processes is
then measured using non-dispersive infrared spectroscopy.
    The currently approved methods for the analysis of TOC in drinking
water are listed in 40 CFR 141.131(d)(3). The approved oxidation
method, Standard Method 5310 C-00 (APHA 2000b), may not completely
oxidize certain organic compounds. Hach Method 10261 uses a more
efficient advanced oxidation process to ensure more complete oxidation.
    A multi-laboratory validation study was conducted to compare the
performance of Hach Method 10261 to the approved Standard Method 5310
C-00. Multiple finished drinking water samples drawn from both ground
water and surface water sources were used in the validation study.
Precision, accuracy and sensitivity data were collected by analyzing
drinking water samples fortified with varying concentrations of TOC.
The results are summarized in the validation study report (Hach Company
2015f). EPA has determined that Hach Method 10261 is equally as
effective as the approved Standard Method 5310 C-00. The basis for this
determination is discussed in Adams and Smith (2016). Therefore, EPA is
approving Hach Method 10261 for the analysis of TOC in drinking water.
Hach Method 10261 can be obtained from Hach Company, 5600 Lindbergh
Drive, Loveland, Colorado 80539. (http://www.hach.com).
    4. Hach Method 10267--Spectrophotometric Measurement of Total
Organic Carbon (TOC) in Finished Drinking Water (Hach Company 2015g).
Hach Method 10267 is used for the determination of TOC in drinking
water using acid persulfate digestion and visible spectrum
spectrophotometry. In this method, samples are oxidized using acid
persulfate digestions to convert TOC into carbon dioxide. The generated
carbon dioxide is passed through a gas-permeable membrane into an
indicator solution that is measured spectrophotometrically at 435 nm.
Hach Method 10267 uses pre-packaged reagents to simplify sample
preparation and quickly perform the analysis. Interfering inorganic
carbon is removed from the sample prior to digestion by acidification
and agitation.
    The currently approved methods for the analysis of TOC in drinking
water are listed in 40 CFR 141.131(d)(3). A multi-laboratory validation
study was conducted to compare the performance of Hach Method 10267 to
the approved Standard Method 5310 C-00 (APHA 200b). Multiple finished
drinking water samples drawn from both ground water and surface water
sources were used in the validation study. Precision, accuracy and
sensitivity data were collected by analyzing drinking water samples
fortified with varying concentrations of TOC. The results are
summarized in the validation study report (Hach Company 2015h). EPA has
determined that Hach Method 10267 is equally as effective as the
approved Standard Method 5310 C-00. The basis for this determination is
discussed in Adams and Smith (2016). Therefore, EPA is approving Hach
Method 10267 for the analysis of TOC in drinking water. Hach Method
10267 can be obtained from Hach Company, 5600 Lindbergh Drive,
Loveland, Colorado 80539. (http://www.hach.com).
    5. Hach Method 10272--Spectrophotometric Measurement of Copper in
Finished Drinking Water (Hach Company 2015i). In Hach Method 10272,
cuprous copper is measured colorimetrically by complexation with
bicinchoninic acid. The intensity in color is proportional to the
copper concentration, and spectrophotometer measurements are taken at
560 nm. Cupric copper present in samples is chemically reduced to
cuprous copper. Metal and hardness interferences in samples are
mitigated through the use of a chelating agent. The method is performed
through the use of a copper Chemkey and portable analyzer.
    The currently approved methods for the analysis of copper in
drinking water are listed in the table at 40 CFR 141.23(k)(1). The
approved methods are based on atomic spectroscopy technologies. Hach
Method 10272 uses a spectrophotometer, simple color/absorbance
measurements to determine copper concentrations, and incorporates
portability and streamlining into the analysis.
    A multi-laboratory validation study was conducted to compare the
performance of Hach Method 10272 to EPA Method 200.7 (USEPA 1994), one
of the approved methods for the analysis of copper in drinking water.
Multiple finished drinking water samples drawn from both ground water
and surface water sources were used in the validation study. Precision,
accuracy and sensitivity data were collected by analyzing drinking
water samples fortified with varying concentrations of copper
standards. The results are summarized in the validation study report
(Hach Company 2015j). EPA has determined that Hach Method 10272 is
equally as effective as the approved EPA Method 200.7. The basis for
this determination is discussed in Adams and Smith (2016). Therefore,
EPA is approving Hach Method 10272 for the analysis of copper in
drinking water. Hach Method 10272 can be obtained from Hach Company,
5600 Lindbergh Drive, Loveland, Colorado 80539. (http://www.hach.com).
    6. Hach Method 10258--Determination of Turbidity by 360[deg]
Nephelometry (Hach Company 2016). In Hach Method 10258 turbidity is
determined in conventional-filtered and membrane-filtered treated
drinking water using a 360 degree nephelometer.

In this method, a non-incandescent light source operates at a
wavelength of 660 + 30 nm and light scattered by the sample is
collected and detected at an angle 90 degrees to the incident light,
360 degrees around the sample vial. This design offers improved
sensitivity (minimum quantitation limit of 0.0005 Nephelometric
Turbidity Units (NTU) and resolution (0.0001 NTU) relative to the
approved methods.
    The currently approved methods for the analysis of turbidity in
treated drinking water are listed in the regulations at 40 CFR
141.74(a)(1). A multi-facility validation study was conducted to
compare the performance of Hach Method 10258 to the approved Hach
FilterTrak Method 10133 (Hach Company 2000) for the analysis of
turbidity in treated drinking water. Seven public drinking water
facilities participated in the study. Three facilities produced treated
water using both conventional-filtration and membrane-filtration, two
facilities produced only conventional-filtration treated water, and two
facilities produced only membrane-filtration treated water. Source
waters encompassed both surface waters and ground waters under the
direct influence of surface water. Turbidity comparison data were
collected at each facility by operating the instrument collecting the
Hach Method 10258 turbidity data in parallel with an instrument
collecting turbidity data using the approved Hach FilterTrack Method
10133. Precision and accuracy (based on recovery of matrix spike
injections) data were collected over a range of spike levels (0.0015-
0.500 NTU) and calibration verification data were collected from each
facility. The results are summarized in the validation study report
(Hach Company 2014). EPA has determined that Hach Method 10258 is
equally as effective as the approved Hach FilterTrak Method 10133. The
basis for this determination is discussed in Adams and Smith (2016).
Therefore, EPA is approving Hach Method 10258 for the analysis of
turbidity in treated drinking water. Hach Method 10258 can be obtained
from Hach Company, 5600 Lindbergh Drive, Loveland, Colorado 80539.

    7. Nitrate Elimination Company, Inc. (NECi)--Method for Nitrate
Reductase Nitrate-Nitrogen Analysis of Drinking Water (NECi 2016a). The
NECi nitrate reductase method is used for the determination of nitrate
plus nitrite (as nitrogen) in drinking water. In this method, a
eukaryotic nitrate reductase is used to catalyze the conversion of
nitrate to nitrite in the presence of nicotinamide adenine dinucleotide
as a reductant in a buffer with a near neutral pH. The combined nitrite
(both the original and reduced nitrate) is reacted with sulfanilamide
and N-(1-napthyl) ethylenediamine dihydrochloride to produce a
chromophore. The combined nitrite concentration is then measured
spectrophotometrically at ~540 nm. The method entails the use of a
discrete analyzer that incorporates a spectrophotometric detector.
    The currently approved methods for the analysis of nitrate and
nitrite in drinking water are listed in 40 CFR 141.23(k)(1). The
approved EPA Method 353.2 (USEPA 1993a) uses cadmium to reduce nitrate
to nitrite and subsequently measures the combined nitrite
colorimetrically. The NECi nitrate reductase method provides an
environmentally friendly approach to nitrate-nitrogen analysis by
eliminating the use of toxic cadmium and requires only a fraction of
the sample volume used in the approved EPA method.
    A multi-laboratory validation study was conducted to compare the
performance of the NECi nitrate reductase method to the approved EPA
Method 353.2. Multiple finished drinking water samples drawn from both
ground water and surface water sources were used in the validation
study. Precision, accuracy and sensitivity data were collected by
analyzing drinking water samples fortified with varying concentrations
of nitrate standards. The results are summarized in the validation
study report (NECi 2016b). EPA has determined that the NECi nitrate
reductase method is equally as effective as the approved EPA Method
353.2. The basis for this determination is discussed in Adams and
Wendelken (2016). Therefore, EPA is approving the NECi nitrate
reductase method for the analysis of nitrate and nitrite in drinking
water. The NECi nitrate reductase method can be obtained from the
Nitrate Elimination Company, Inc. (NECi) at Superior Enzymes, Inc., 334
Hecla St., Lake Linden, Michigan 49945.
    8. Thermo Fisher Scientific Drinking Water Orthophosphate Method
for Thermo Scientific Gallery Discrete Analyzer (Thermo Fisher 2016a).
The Thermo Fisher orthophosphate drinking water method employing Thermo
Scientific Gallery discrete analyzers is used for the colorimetric
determination of orthophosphate in drinking water. In this method,
orthophosphate is reacted with ammonium molybdate and antimony
potassium tartrate in an acidic medium to form an antimony-phospho-
molybdate complex. The complex is subsequently reduced by ascorbic acid
to form an intensely blue complex that can be measured
spectrophotometrically at 880 nm.
    The currently approved methods for the analysis of orthophosphate
in drinking water are listed in 40 CFR 141.23(k)(1). Standard Methods
4500-P E (APHA, 1995) is an approved method that uses ascorbic acid to
reduce reacted orthophosphate into a complex that can be measured
spectrophotometrically. The Thermo Fisher orthophosphate method
incorporates an automated discrete analyzer, which minimizes the use of
chemical reagents, generation of waste and human handling errors.
    A validation study was conducted to compare the performance of the
automated Thermo Fisher orthophosphate discrete analyzer method to the
approved Standard Method 4500-P E. Multiple finished drinking water
samples drawn from both ground water and surface water sources were
used in the validation study. Precision, accuracy and sensitivity data
were collected by analyzing drinking water samples fortified with
varying concentrations of orthophosphate standards. The results are
summarized in the validation study report (Thermo Fisher 2016b). EPA
has determined that the Thermo Fisher discrete analyzer method for
orthophosphate is equally as effective as the approved Standard Method
4500-P E. Therefore, EPA is approving the Thermo Fisher method for the
analysis of orthophosphate in treated drinking water. The basis for
this determination is discussed in Adams (2016). The Thermo Fisher
discrete analyzer method for orthophosphate can be obtained from Thermo
Fisher Scientific, Ratastie 2, 01620 Vantaa, Finland.
    9. Mitchell Method M5331, Revision 1.2--Determination of Turbidity
by LED or Laser Nephelometry (Mitchell 2016). Mitchell Method M5331,
Revision 1.1 (Mitchell 2009) was approved for the determination of
turbidity in drinking water by light emitting diode (LED) nephelometry
in the August 2009 expedited methods approval action (USEPA 2009). The
currently approved methods for turbidity are listed in 40 CFR
141.74(a)(1) and different sources, including lasers, have been
approved. The Mitchell Method M5331 has been updated to incorporate the
option of using a solid-state laser in place of a LED as the light
source for the turbidimeter. The vendor cites multiple advantages
associated with the use of lasers relative to LEDs (Mitchell 2015).
Mitchell Method M5331, Revision 1.1 specifies a light source of 525
 15 nm, and now lasers at 520 nm and 532 nm are readily
available. In addition to

meeting the specified wavelength range, solid-state lasers can offer
longer source lifetimes, greater stability, and improved stray light
rejection. The updated method is the same as the approved Mitchell
Method M5331, Revision 1.1 relative to the divergence of the light
source measurement area, the detector, and all other instrumental
features. EPA has determined that the updated method is equally as
effective as the promulgated EPA Method 180.1 (USEPA 1993b), which
established the criteria for nephelometric determination of turbidity.
The basis for this determination is discussed in Wendelken and Smith
(2016). Therefore, EPA is approving Mitchell Method M5331, Revision 1.2
for the determination of turbidity in drinking water. Mitchell Method
M5331, Revision 1.2 can be obtained from Leck Mitchell, Ph.D., PE, 656
Independence Valley Drive, Grand Junction, Colorado 81507.

 IV. Statutory and Executive Order Reviews

    As noted in Section II, under the terms of SDWA Section 1401(1),
this streamlined method approval action is not a rule. Accordingly, the
Congressional Review Act, 5 U.S.C. 801 et seq., as added by the Small
Business Regulatory Enforcement Fairness Act of 1996, does not apply
because this action is not a rule for purposes of 5 U.S.C. 804(3).
Similarly, this action is not subject to the Regulatory Flexibility Act
because it is not subject to notice and comment requirements under the
Administrative Procedure Act or any other statute. In addition, because
this approval action is not a rule but simply makes alternative testing
methods available as options for monitoring under SDWA, EPA has
concluded that other statutes and executive orders generally applicable
to rulemaking do not apply to this approval action.

SUPPLEMENTARY INFORMATION:

Authority for This Rulemaking

    The FAA's authority to issue rules regarding aviation safety is
found in Title 49 of the United States Code. 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. This rulemaking is promulgated under the authority described
in Subtitle VII, Part A, Subpart I, Section 40103. Under that section,
the FAA is charged with prescribing regulations to assign the use of
airspace necessary to ensure the safety of aircraft and the efficient
use of airspace. This regulation is within the scope of that authority
as it would amend the Class D airspace, the Class E surface airspace,
and the Class E airspace extending upward from 700 feet above the
surface at Mansfield Lahm Municipal Airport, Mansfield, OH, to support
instrument flight rule operations at this airport.

Comments Invited

    Interested parties are invited to participate in this proposed
rulemaking by submitting such written data, views, or arguments, as
they may desire. Comments that provide the factual basis supporting the
views and suggestions presented are particularly helpful in developing
reasoned regulatory decisions on the proposal. Comments are
specifically invited on the overall regulatory, aeronautical, economic,
environmental, and energy-related aspects of the proposal.
Communications should identify both docket numbers and be submitted in
triplicate to the address listed above. Commenters wishing the FAA to
acknowledge receipt of their comments on this notice must submit with
those comments a self-addressed, stamped postcard on which the
following statement is made: ``Comments to Docket No. FAA-2022-0714/
Airspace Docket No. 22-AGL-23.'' The postcard will be date/time stamped
and returned to the commenter.
    All communications received before the specified closing date for
comments will be considered before taking action on the proposed rule.
The proposal contained in this notice may be changed in light of the
comments received. A report summarizing each substantive public contact
with FAA personnel concerned with this rulemaking will be filed in the
docket.

Availability of NPRMs

    An electronic copy of this document may be downloaded through the
internet at https://www.regulations.gov. Recently published rulemaking
documents can also be accessed through the FAA's web page at https://www.faa.gov/air_traffic/publications/airspace_amendments/.
    You may review the public docket containing the proposal, any
comments received, and any final disposition in person in the Dockets
Office (see the ADDRESSES section for the address and phone number)
between 9:00 a.m. and 5:00 p.m., Monday through Friday, except federal
holidays. An informal docket may also be examined during normal
business hours at the Federal Aviation Administration, Air Traffic
Organization, Central Service Center, Operations Support Group, 10101
Hillwood Parkway, Fort Worth, TX 76177.

Availability and Summary of Documents for Incorporation by Reference

    This document proposes to amend FAA Order JO 7400.11F, Airspace
Designations and Reporting Points, dated August 10, 2021, and effective
September 15, 2021. FAA Order JO 7400.11F is publicly available as
listed in the ADDRESSES section of this document. FAA Order JO 7400.11F
lists Class A, B, C, D, and E airspace areas, air traffic service
routes, and reporting points.

The Proposal

    The FAA is proposing an amendment to 14 CFR part 71 by:
    Amending the Class D airspace at Mansfield Lahm Municipal Airport,
Mansfield, OH, by removing the Mansfield VORTAC and associated
extension from the airspace legal description as they are no longer
needed; and replacing the outdated terms ``Notice to Airmen'' with
``Notice to Air Missions'' and ``Airport/Facility Directory'' with
``Chart Supplement'';
    Amending the Class E surface airspace at Mansfield Lahm Municipal
Airport by removing the Mansfield VORTAC and associated extension from
the airspace legal description as they are no longer needed; and adding
missing part-time language to the airspace legal description;
    And amending the Class E airspace extending upward from 700 feet
above the surface at Mansfield Lahm Municipal Airport by removing the
extensions to the southeast, northwest, and southwest of the airport
from the airspace legal description as they are no longer needed;
amending the extension northeast of the airport to within 2 (decreased
from 4) miles each side of the 047[deg] bearing from the airport
extending from the 6.9-mile radius of the airport to 8.9 (decreased
from 11.2) miles northeast of the airport; amending the extension
southeast of the VORTAC to within 9.9 miles northeast and 6.1 miles
southwest (previously 4.4 miles each side) of the Mansfield VORTAC
133[deg] (previously 130[deg]) radial extending from the 6.9-mile
radius of the airport to 19 (increased from 13.8) miles southeast of
the VORTAC; amending the extension northwest of the VORTAC to within
9.9 miles southwest and 6.1 miles northeast (previously 6.1 miles each
side) of the Mansfield VORTAC 310[deg] (previously 307[deg]) radial
extending from the 6.9-mile radius of the airport to 10 (decreased from
13.3) miles northwest of the VORTAC; removing the cities associated
with the airports in the airspace legal description to comply with
changes to FAA Order JO 7400.2N, Procedures for Handling Airspace
Matters; and updating the geographic coordinates of the Mansfield
VORTAC to coincide with the FAA's aeronautical database.
    This action is due to a biennial airspace review.
    Class D and E airspace designations are published in paragraphs
5000, 6002, and 6005, respectively, of FAA Order JO 7400.11F, dated
August 10, 2021, and effective September 15, 2021, which is
incorporated by reference in 14 CFR 71.1. The Class D and E airspace
designations listed in this document will be published subsequently in
FAA Order JO 7400.11.
    FAA Order JO 7400.11, Airspace Designations and Reporting Points,
is published yearly and effective on September 15.

Regulatory Notices and Analyses

    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, is
non-controversial and unlikely to result in adverse or negative
comments. It, therefore: (1) is not a ``significant regulatory action''
under Executive Order 12866; (2) is not a ``significant rule'' under
DOT Regulatory Policies and Procedures (44 FR 11034; February 26,
1979); and (3) does not warrant preparation of a regulatory evaluation
as the anticipated impact is so minimal. Since this is a routine matter
that will only affect air traffic procedures and air navigation, it is
certified that this rule, when promulgated, would not have a
significant economic impact on a substantial number of small entities
under the criteria of the Regulatory Flexibility Act.

Environmental Review

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

SECURITIES AND EXCHANGE COMMISSION

[SEC File No. 270-522; OMB Control No. 3235-0586]

Proposed Collection; Comment Request

Upon Written Request, Copies Available From: Securities and Exchange
Commission, Office of FOIA Services, 100 F Street NE, Washington, DC
20549-2736.

Extension:
    Rule 38a-1

    Notice is hereby given that, pursuant to the Paperwork Reduction
Act of 1995 (44 U.S.C. 3501 et seq.), the Securities and Exchange
Commission (the ``Commission'') is soliciting comments on the
collection of information summarized below. The Commission plans to
submit this existing collection of information to the Office of
Management and Budget for extension and approval.
    Rule 38a-1 (17 CFR 270.38a-1) under the Investment Company Act of
1940 (15 U.S.C. 80a) (``Investment Company Act'') is intended to
protect investors by fostering better fund compliance with securities
laws. The rule requires every registered investment company and
business development company (``fund'') to: (i) Adopt and implement
written policies and procedures reasonably designed to prevent
violations of the federal securities laws by the fund, including
procedures for oversight of compliance by each investment adviser,
principal underwriter, administrator, and transfer agent of the fund;
(ii) obtain the fund board of directors' approval of those policies and
procedures; (iii) annually review the adequacy of those policies and
procedures and the policies and procedures of each investment adviser,
principal underwriter, administrator, and transfer agent of the fund,
and the effectiveness of their implementation; (iv) designate a chief
compliance officer to administer the fund's policies and procedures and
prepare an annual report to the board that addresses certain specified
items relating to the policies and procedures; and (v) maintain for
five years the compliance policies and procedures and the chief
compliance officer's annual report to the board.
    The rule contains certain information collection requirements that
are designed to ensure that funds establish and maintain comprehensive,
written internal compliance programs. The information collections also
assist the Commission's examination staff in assessing the adequacy of
funds' compliance programs.
    While Rule 38a-1 requires each fund to maintain written policies
and procedures, most funds are located within a fund complex. The
experience of the Commission's examination and oversight staff suggests
that each fund in a complex is able to draw extensively from the fund
complex's ``master'' compliance program to assemble appropriate
compliance policies and procedures. Many fund complexes already have
written policies and procedures documenting their compliance programs.
Further, a fund needing to develop or revise policies and procedures on
one or more topics in order to achieve a comprehensive compliance
program can draw on a number of outlines and model programs available
from a variety of industry representatives, commentators, and
organizations.
    There are approximately 4,093 funds subject to Rule 38a-1. Among
these funds, 101 were newly registered in the past year. These 101
funds, therefore, were required to adopt and document the policies and
procedures that make up their compliance programs. Commission staff
estimates that the average annual hour burden for a fund to adopt and
document these policies and procedures is 105 hours. Thus, we estimate
that the aggregate annual burden hours associated with the adoption and
documentation requirement is 10,605 hours.

    All funds are required to conduct an annual review of the adequacy
of their existing policies and procedures and the policies and
procedures of each investment adviser, principal underwriter,
administrator, and transfer agent of the fund, and the effectiveness of
their implementation. In addition, each fund chief compliance officer
is required to prepare an annual report that addresses the operation of
the policies and procedures of the fund and the policies and procedures
of each investment adviser, principal underwriter, administrator, and
transfer agent of the fund, any material changes made to those policies
and procedures since the date of the last report, any material changes
to the policies and procedures recommended as a result of the annual
review, and certain compliance matters that occurred since the date of
the last report. The staff estimates that each fund spends 49 hours per
year, on average, conducting the annual review and preparing the annual
report to the board of directors. Thus, we estimate that the annual
aggregate burden hours associated with the annual review and annual
report requirement is 200,557 hours.
    Finally, the staff estimates that each fund spends 6 hours
annually, on average, maintaining the records required by proposed Rule
38a-1. Thus, the aggregate annual burden hours associated with the
recordkeeping requirement is 24,558 hours.
    In total, the staff estimates that the aggregate annual information
collection burden of Rule 38a-1 is 235,720 hours.
    The estimate of average burden hours is made solely for the
purposes of the Paperwork Reduction Act. The estimate is based on
communications with industry representatives, and is not derived from a
comprehensive or even a representative survey or study. Responses will
not be kept confidential. 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.
    Written comments are invited on: (i) Whether the collection of
information is necessary for the proper performance of the functions of
the Commission, including whether the information has practical
utility; (ii) the accuracy of the Commission's estimate of the
burden(s) of the collection of information; (iii) ways to enhance the
quality, utility, and clarity of the information collected; and (iv)
ways to minimize the burden of the collection of information on
respondents, including through the use of automated collection
techniques or other forms of information technology. Consideration will
be given to comments and suggestions submitted in writing within 60
days of this publication.
    Please direct your written comments to David Bottom, Director/Chief
Information Officer, Securities and Exchange Commission, c/o Cynthia
Roscoe, 100 F Street NE, Washington, DC 20549; or send an email to:
