The Environmental Protection
Agency (EPA) is announcing the
Agency’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 the
EPA to approve the use of alternative
testing methods through publication in
the Federal Register. The EPA is using
this authority to make 100 additional
methods available for analyzing
drinking water samples. This expedited
approach provides public water
systems, laboratories, and primacy

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. The 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 also measure contaminants in
water samples. When the 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. The 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 testing method that has
been approved in this action or in prior
expedited approval actions. Categories
and entities that may ultimately be
interested in this expedited methods
approval action include:

II. Background
A. What is the purpose of this action?
In this action, the EPA is approving
100 analytical methods for determining
contaminant concentrations in drinking
water samples collected under the
SDWA. Regulated entities required to
sample and monitor may use either the
testing methods already established in
existing national primary drinking water
regulations or the alternative testing
methods being approved under 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 the EPA’s drinking
water methods website at https://
www.epa.gov/dwanalyticalmethods.
B. What is the basis for this action?
When the 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), the
PO 00000
Frm 00015
Fmt 4700
Sfmt 4700
SDWA allows the EPA to approve the
use of the alternative testing method
through publication in the Federal
Register (see section 1401(1) of the
SDWA). The EPA is using this approval
authority to make 100 additional
methods available for determining
contaminant concentrations in drinking
water samples collected under the
SDWA. The EPA has determined that,
for each contaminant or group of
contaminants listed in Section III of this
action, the additional testing methods
being approved are as effective as one or
more of the testing methods already
approved in the regulations for those
contaminants. Section 1401(1) of the
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 100 analytical methods
legally available as options for meeting
the EPA’s monitoring requirements.
This action does not add regulatory
language; however, for informational
purposes, the action updates an
appendix to the regulations at 40 CFR
part 141, which lists all methods

Federal Register / Vol. 83, No. 198 / Friday, October 12, 2018 / Rules and Regulations
approved under section 1401(1) of the
SDWA. Accordingly, while this action is
not a rule, it is updating CFR text and
therefore is being published under the
‘‘Final Rules’’ section of the Federal
Register.
III. Summary of Approvals
The EPA is approving 100 methods
that are equally effective relative to
methods previously promulgated in the
regulations. This action adds these 100
methods to Appendix A to subpart C of
40 CFR part 141.
A. Methods Developed by the EPA
1. EPA Method 900.0, Revision 1.0,
Determination of Gross Alpha and Gross
Beta in Drinking Water (USEPA 2018).
EPA Method 900.0 (USEPA 1980) was
promulgated in the drinking water
regulations at 40 CFR 141.25(a) as a
screening method for alpha- and betaemitting radionuclides. EPA Method
900.0, Revision 1.0 was developed in
response to comments from
radiochemistry stakeholders indicating
that the older, approved method does
not address newer instrumental
capabilities such as simultaneous alpha/
beta counting and the concomitant need
to properly address crosstalk. Moreover,
stakeholders requested that a method
revision provide more in-depth
calibration details and quality control
criteria to assure a more robust
procedure capable of yielding improved
consistency in generating and
evaluating analytical results. EPA
Method 900.0, Revision 1.0 addresses
those concerns and also corrects specific
disparities between requirements in the
promulgated Method 900.0 and the
Standard methods,

criteria defined in the regulations. For
example, the approved Method 900.0
defines americium-241 as the gross
alpha calibrant. However, americium241 is not approved in the regulations
at 40 CFR 141.25(a); footnote 11 to the
table at 40 CFR 141.25(a) states that only
natural uranium and thorium-230 are
approved calibration standards for gross
alpha evaporative methods (i.e., Method
900.0). Americium-241 is only approved
as an alpha calibrant for co-precipitation
methods.
The revised method also addresses
the important issue of the time interval
involved between sample preparation
and counting. Timing events can have a
significant impact on gross alpha
results. The gross alpha maximum
contaminant level specified at 40 CFR
141.66(c) is 15 pCi/L and excludes
radon and uranium activity. The
promulgated method specifies a
minimum 72-hour hold time after
preparation before counting the
samples. Such a delay can allow radon
ingrowth along with its alpha-emitting
progeny. The revised method eliminates
the hold time in order to more
accurately meet the intent of the gross
alpha maximum contaminant level
specification.
The EPA has determined that EPA
Method 900.0, Revision 1.0 is equally as
effective for determining gross alpha
and gross beta radioactivity as the
promulgated method. The basis for this
determination is discussed in greater
detail in Smith 2018a. Therefore, the
EPA is approving EPA Method 900.0,
Revision 1.0 for the routine
determination of gross alpha and gross
beta radioactivity in drinking water.
Approved method
PO 00000
1. Standard Methods for the
Examination of Water and Wastewater
(Standard Methods). The 23rd edition of
Standard Methods for the Examination
of Water and Wastewater (APHA 2017)
was published in July 2017. The EPA
compared 89 methods in the 23rd
edition to earlier versions of those
methods that are promulgated in 40 CFR
parts 141 and 143. Changes between the
promulgated version and the version of
each method published in the 23rd
edition are summarized in Smith and
Wendelken (2018) and Best (2018). The
revisions primarily involve editorial
changes (e.g., correction of errors,
procedural clarifications, and
reorganization of text). Errors in the
nitrate methods (4500–NO3¥ D, E, and
F) have been addressed in an
appropriate errata sheet prepared for the
23rd edition (APHL 2018). The methods
in the following table are the same as
the earlier approved versions with
respect to the sample handling
protocols, analytical procedures, and
method performance data. For these
reasons, the EPA has concluded that the
versions in the 23rd edition are equally
effective relative to the promulgated
versions in the regulations. Therefore,
the EPA is approving the use of 89
Standard Methods in the 23rd edition
for the contaminants and their
respective regulations listed in the
following table:

Two additional methods from earlier
editions of Standard Methods for the
Examination of Water and Wastewater
are being approved under this action:
Standard Method 4500-CN¥ C in the
21st edition (APHA 2005) and Standard
Method 4500-CN¥ C in the 22nd edition
(APHA 2012). Also, the identical online
version, Standard Method 4500-CN¥
C–99 (APHA 1999d) is being approved.
The originally approved method,
Standard Method 4500-CN¥ C in the
20th edition (APHA 1998) specified
addition of magnesium chloride in the
distillation. Beginning with the 1999
online method, and in the subsequent
21st and 22nd editions, Standard
Methods made the addition of
magnesium chloride optional, without
providing supporting data to verify that
distillation efficiency was not adversely
affected when magnesium chloride was
not used. As a result, the EPA did not
approve Standard Method 4500-CN¥ C
in the 1999 online method and
subsequent editions of Standard

Methods for the Examination of Water
and Wastewater. The distillation
performed in Standard Method 4500CN¥ C is required prior to conducting
the analyses for all of the other
approved cyanide methods. As a result,
laboratories conducting cyanide
analyses for drinking water compliance
have had to rely on the approved
version in the 20th edition. That may
result in confusion because laboratories
that also conduct cyanide analyses for
wastewaters use the more recently
published Standard Methods. In order
to address this issue, the EPA is
approving Standard Method 4500-CN¥
C in the editions and online version as
stated above, but with the requirement
to add magnesium chloride in the
distillation. The cyanide entry in
Appendix A to subpart C of part 141 has
been revised to clarify this requirement.
The 23rd edition can be obtained from
the American Public Health Association
(APHA), 800 I Street NW, Washington,

2. ASTM International. The EPA
compared the most recent versions of
five ASTM International methods to the
earlier versions of those methods that
are promulgated in 40 CFR part 141.
Most of the changes in the updated
versions include additional quality
control specifications.
Changes between the earlier approved
version and the most recent version of
each method are described more fully in
Smith (2018b). Besides additional
quality control, the revisions involve
(primarily) editorial changes (e.g.,
updated references, definitions,
terminology, procedural clarifications,
and reorganization of text). The revised
methods are the same as the
promulgated versions with respect to
sample collection and handling
protocols, sample preparation,
analytical methodology, and method
performance data; thus, the EPA finds
E:\FR\FM\12OCR1.SGM

Federal Register / Vol. 83, No. 198 / Friday, October 12, 2018 / Rules and Regulations

C. Methods Developed by Vendors
1. Hach Method 10258, Rev. 2.0.
Determination of Turbidity by 360°
Nephelometry, March 2018 (Hach
Company 2018a). In July 2016, Hach
Method 10258, Rev. 1.0 (Hach Company
2016) was approved in an expedited
methods approval action (USEPA 2016)
as an equally effective alternate method
to the Hach FilterTrak Method 10133
(Hach Company 2000), which is
approved at 40 CFR 141.74(a)(1), for
determination of turbidity in drinking
water.
Turbidimeter calibration and
calibration verification have remained
unchanged since promulgation of
turbidity methods in 40 CFR
141.74(a)(1). Calibration and quarterly
calibration validation through analysis
of a Quality Control Sample (QCS)
require preparation of a primary
calibration standard. Sealed standards
are considered as secondary calibration
standards and used only as calibration
verification checks between the
quarterly calibration validation QCS
evaluations.
Public water systems utilize multiple
turbidimeters and many of the units are
in line with process streams. The time
and cost associated with preparing
quarterly primary calibration standards
can be significant. In 2016, Hach
Company began to manufacture glass
flame-sealed vials prefilled with
StablCalTM, which is an approved
primary calibration standard. From
December 2016 through March 2018,
Hach conducted a long-term stability
study with a set of sealed vials
containing StablCal to determine
whether the integrity of the vials and
stability of the primary calibration
standard could be maintained. After 515
days (1.4 years), the sealed StablCal
primary calibration standards exhibited
a %bias of <0.1% and relative standard
deviation of 0.7% compared to the
initial certified turbidity values,
indicating that no degradation of the

StablCal primary calibration standard
occurred. The results of this study are
discussed further in the validation
report (Hach Company 2018b).
Hach Method 10258, Rev. 2.0 is an
updated version of the promulgated
Hach Method 10258, Rev. 1.0. The
updated method provides for use of
glass flame-sealed vials prefilled with
StablCal as primary calibration
standards, secondary calibration
verification standards, and QCS checks.
The EPA has determined that Hach
Method 10258, Rev. 2.0 is equally as
effective as the promulgated Hach
Method 10258, Rev. 1.0. The basis for
this determination is discussed in
Adams and Smith (2018). Therefore, the
EPA is approving Hach Method 10258,
Rev. 2.0 for the determination of
turbidity in drinking water. Hach
Method 10258, Rev. 2.0 can be obtained
from Hach Company, 5600 Lindbergh
Drive, P.O. Box 389, Loveland, Colorado
80539.
2. Hach Method 8195, Rev. 3.0.
Determination of Turbidity by
Nephelometry, March 2018 (Hach
Company 2018c). On April 20, 1998, the
EPA Office of Water issued a letter
(USEPA 1998) addressing the use of
Hach Method 8195 (Hach Company
1997) as an alternate method to EPA
Method 180.1 (USEPA 1993) for
drinking water compliance monitoring
of turbidity. Hach Method 8195
established the same requirements for
primary calibration standards,
secondary calibration verification
standards, and QCS checks as described
for Hach Method 10258, Rev. 1.0 in
Section III.C.1 of this action. Hach
Method 8195, Rev. 3.0 is an updated
version of the 1997 Hach Method 8195.
The updated method provides for use of
glass flame-sealed vials prefilled with
StablCal as primary calibration
standards, secondary calibration
verification standards, and QCS checks.
The EPA has determined that Hach
Method 8195, Rev. 3.0 is equally as
effective as the 1997 Hach Method 8195
and EPA Method 180.1. The basis for
this determination is discussed in
Adams and Smith (2018). Therefore, the
EPA is approving Hach Method 8195,
PO 00000

following table:

IV. Statutory and Executive Order
Reviews
As noted in Section II of this action,
under the terms of the 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 the SDWA, the EPA
has concluded that other statutes and
executive orders generally applicable to
rulemaking do not apply to this
approval action.

ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (EPA) is announcing the
Agency'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 the EPA to approve the use of alternative testing
methods through publication in the Federal Register. The EPA is using
this authority to make 100 additional methods available for analyzing
drinking water samples. This expedited approach provides public water
systems, laboratories, and primacy

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. The 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 also measure contaminants in water samples. When
the 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. The 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 testing method that has been approved in this action
or in prior expedited approval actions. Categories and entities that
may ultimately be interested in this expedited methods approval action

II. Background
A. What is the purpose of this action?
In this action, the EPA is approving 100 analytical methods for
determining contaminant concentrations in drinking water samples
collected under the SDWA. Regulated entities required to sample and
monitor may use either the testing methods already established in
existing national primary drinking water regulations or the alternative
testing methods being approved under 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 the EPA's drinking water methods
website at https://www.epa.gov/dwanalyticalmethods.
B. What is the basis for this action?
When the 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), the SDWA allows the EPA to
approve the use of the alternative testing method through publication
in the Federal Register (see section 1401(1) of the SDWA). The EPA is
using this approval authority to make 100 additional methods available
for determining contaminant concentrations in drinking water samples
collected under the SDWA. The EPA has determined that, for each
contaminant or group of contaminants listed in Section III of this
action, the additional testing methods being approved are as effective
as one or more of the testing methods already approved in the
regulations for those contaminants. Section 1401(1) of the 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 100 analytical methods legally available as options for
meeting the EPA's monitoring requirements.
This action does not add regulatory language; however, for
informational purposes, the action updates an appendix to the
regulations at 40 CFR part 141, which lists all methods
[[Page 51638]]
approved under section 1401(1) of the SDWA. Accordingly, while this
action is not a rule, it is updating CFR text and therefore is being
published under the ``Final Rules'' section of the Federal Register.
III. Summary of Approvals
The EPA is approving 100 methods that are equally effective
relative to methods previously promulgated in the regulations. This
action adds these 100 methods to Appendix A to subpart C of 40 CFR part
141.
A. Methods Developed by the EPA
1. EPA Method 900.0, Revision 1.0, Determination of Gross Alpha and
Gross Beta in Drinking Water (USEPA 2018). EPA Method 900.0 (USEPA
1980) was promulgated in the drinking water regulations at 40 CFR
141.25(a) as a screening method for alpha- and beta-emitting
radionuclides. EPA Method 900.0, Revision 1.0 was developed in response
to comments from radiochemistry stakeholders indicating that the older,
approved method does not address newer instrumental capabilities such
as simultaneous alpha/beta counting and the concomitant need to
properly address crosstalk. Moreover, stakeholders requested that a
method revision provide more in-depth calibration details and quality
control criteria to assure a more robust procedure capable of yielding
improved consistency in generating and evaluating analytical results.
EPA Method 900.0, Revision 1.0 addresses those concerns and also
corrects specific disparities between requirements in the promulgated
Method 900.0 and the criteria defined in the regulations. For example,
the approved Method 900.0 defines americium-241 as the gross alpha
calibrant. However, americium-241 is not approved in the regulations at
40 CFR 141.25(a); footnote 11 to the table at 40 CFR 141.25(a) states
that only natural uranium and thorium-230 are approved calibration
standards for gross alpha evaporative methods (i.e., Method 900.0).
Americium-241 is only approved as an alpha calibrant for co-
precipitation methods.
The revised method also addresses the important issue of the time
interval involved between sample preparation and counting. Timing
events can have a significant impact on gross alpha results. The gross
alpha maximum contaminant level specified at 40 CFR 141.66(c) is 15
pCi/L and excludes radon and uranium activity. The promulgated method
specifies a minimum 72-hour hold time after preparation before counting
the samples. Such a delay can allow radon ingrowth along with its
alpha-emitting progeny. The revised method eliminates the hold time in
order to more accurately meet the intent of the gross alpha maximum
contaminant level specification.
The EPA has determined that EPA Method 900.0, Revision 1.0 is
equally as effective for determining gross alpha and gross beta
radioactivity as the promulgated method. The basis for this
determination is discussed in greater detail in Smith 2018a. Therefore,
the EPA is approving EPA Method 900.0, Revision 1.0 for the routine
determination of gross alpha and gross beta radioactivity in drinking
water. EPA Method 900.0 Rev 1.0 is available at the National Service
Center for Environmental Publications.
B. Methods Developed by Voluntary Consensus Standard Bodies (VCSB)
1. Standard Methods for the Examination of Water and Wastewater
(Standard Methods). The 23rd edition of Standard Methods for the
Examination of Water and Wastewater (APHA 2017) was published in July
2017. The EPA compared 89 methods in the 23rd edition to earlier
versions of those methods that are promulgated in 40 CFR parts 141 and
143. Changes between the promulgated version and the version of each
method published in the 23rd edition are summarized in Smith and
Wendelken (2018) and Best (2018). The revisions primarily involve
editorial changes (e.g., correction of errors, procedural
clarifications, and reorganization of text). Errors in the nitrate
methods (4500-NO3- D, E, and F) have been
addressed in an appropriate errata sheet prepared for the 23rd edition
(APHL 2018). The methods in the following table are the same as the
earlier approved versions with respect to the sample handling
protocols, analytical procedures, and method performance data. For
these reasons, the EPA has concluded that the versions in the 23rd
edition are equally effective relative to the promulgated versions in
the regulations. Therefore, the EPA is approving the use of 89 Standard
Methods in the 23rd edition for the contaminants and their respective
regulations listed in the following table:

Two additional methods from earlier editions of Standard Methods
for the Examination of Water and Wastewater are being approved under
this action: Standard Method 4500-CN- C in the 21st edition
(APHA 2005) and Standard Method 4500-CN- C in the 22nd
edition (APHA 2012). Also, the identical online version, Standard
Method 4500-CN- C-99 (APHA 1999d) is being approved. The
originally approved method, Standard Method 4500-CN- C in
the 20th edition (APHA 1998) specified addition of magnesium chloride
in the distillation. Beginning with the 1999 online method, and in the
subsequent 21st and 22nd editions, Standard Methods made the addition
of magnesium chloride optional, without providing supporting data to
verify that distillation efficiency was not adversely affected when
magnesium chloride was not used. As a result, the EPA did not approve
Standard Method 4500-CN- C in the 1999 online method and
subsequent editions of Standard Methods for the Examination of Water
and Wastewater. The distillation performed in Standard Method 4500-
CN- C is required prior to conducting the analyses for all
of the other approved cyanide methods. As a result, laboratories
conducting cyanide analyses for drinking water compliance have had to
rely on the approved version in the 20th edition. That may result in
confusion because laboratories that also conduct cyanide analyses for
wastewaters use the more recently published Standard Methods. In order
to address this issue, the EPA is approving Standard Method 4500-
CN- C in the editions and online version as stated above,
but with the requirement to add magnesium chloride in the distillation.
The cyanide entry in Appendix A to subpart C of part 141 has been
revised to clarify this requirement.
The 23rd edition can be obtained from the American Public Health
Association (APHA), 800 I Street NW, Washington, DC 20001-3710.
Approved online versions are available at https://www.standardmethods.org.
2. ASTM International. The EPA compared the most recent versions of
five ASTM International methods to the earlier versions of those
methods that are promulgated in 40 CFR part 141. Most of the changes in
the updated versions include additional quality control specifications.
Changes between the earlier approved version and the most recent
version of each method are described more fully in Smith (2018b).
Besides additional quality control, the revisions involve (primarily)
editorial changes (e.g., updated references, definitions, terminology,
procedural clarifications, and reorganization of text). The revised
methods are the same as the promulgated versions with respect to sample
collection and handling protocols, sample preparation, analytical
methodology, and method performance data; thus, the EPA finds
[[Page 51641]]
that they are equally effective relative to the promulgated methods.
The EPA is thus approving the use of the following ASTM
International methods for the contaminants and their respective
regulations listed in the following table:

C. Methods Developed by Vendors
1. Hach Method 10258, Rev. 2.0. Determination of Turbidity by
360[deg] Nephelometry, March 2018 (Hach Company 2018a). In July 2016,
Hach Method 10258, Rev. 1.0 (Hach Company 2016) was approved in an
expedited methods approval action (USEPA 2016) as an equally effective
alternate method to the Hach FilterTrak Method 10133 (Hach Company
2000), which is approved at 40 CFR 141.74(a)(1), for determination of
turbidity in drinking water.
Turbidimeter calibration and calibration verification have remained
unchanged since promulgation of turbidity methods in 40 CFR
141.74(a)(1). Calibration and quarterly calibration validation through
analysis of a Quality Control Sample (QCS) require preparation of a
primary calibration standard. Sealed standards are considered as
secondary calibration standards and used only as calibration
verification checks between the quarterly calibration validation QCS
evaluations.
Public water systems utilize multiple turbidimeters and many of the
units are in line with process streams. The time and cost associated
with preparing quarterly primary calibration standards can be
significant. In 2016, Hach Company began to manufacture glass flame-
sealed vials prefilled with StablCalTM, which is an approved
primary calibration standard. From December 2016 through March 2018,
Hach conducted a long-term stability study with a set of sealed vials
containing StablCal to determine whether the integrity of the vials and
stability of the primary calibration standard could be maintained.
After 515 days (1.4 years), the sealed StablCal primary calibration
standards exhibited a %bias of <0.1% and relative standard deviation of
0.7% compared to the initial certified turbidity values, indicating
that no degradation of the StablCal primary calibration standard
occurred. The results of this study are discussed further in the
validation report (Hach Company 2018b).
Hach Method 10258, Rev. 2.0 is an updated version of the
promulgated Hach Method 10258, Rev. 1.0. The updated method provides
for use of glass flame-sealed vials prefilled with StablCal as primary
calibration standards, secondary calibration verification standards,
and QCS checks. The EPA has determined that Hach Method 10258, Rev. 2.0
is equally as effective as the promulgated Hach Method 10258, Rev. 1.0.
The basis for this determination is discussed in Adams and Smith
(2018). Therefore, the EPA is approving Hach Method 10258, Rev. 2.0 for
the determination of turbidity in drinking water. Hach Method 10258,
Rev. 2.0 can be obtained from Hach Company, 5600 Lindbergh Drive, P.O.
Box 389, Loveland, Colorado 80539.
2. Hach Method 8195, Rev. 3.0. Determination of Turbidity by
Nephelometry, March 2018 (Hach Company 2018c). On April 20, 1998, the
EPA Office of Water issued a letter (USEPA 1998) addressing the use of
Hach Method 8195 (Hach Company 1997) as an alternate method to EPA
Method 180.1 (USEPA 1993) for drinking water compliance monitoring of
turbidity. Hach Method 8195 established the same requirements for
primary calibration standards, secondary calibration verification
standards, and QCS checks as described for Hach Method 10258, Rev. 1.0
in Section III.C.1 of this action. Hach Method 8195, Rev. 3.0 is an
updated version of the 1997 Hach Method 8195. The updated method
provides for use of glass flame-sealed vials prefilled with StablCal as
primary calibration standards, secondary calibration verification
standards, and QCS checks. The EPA has determined that Hach Method
8195, Rev. 3.0 is equally as effective as the 1997 Hach Method 8195 and
EPA Method 180.1. The basis for this determination is discussed in
Adams and Smith (2018). Therefore, the EPA is approving Hach Method
8195, Rev. 3.0 for the determination of turbidity in drinking water.
Hach Method 8195, Rev. 3.0 can be obtained from Hach Company, 5600
Lindbergh Drive, P.O. Box 389, Loveland, Colorado 80539.
IV. Statutory and Executive Order Reviews
As noted in Section II of this action, under the terms of the 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 the SDWA, the EPA has concluded that other statutes
and executive orders generally applicable to rulemaking do not apply to
this approval action.
