Federal Register / Vol. 75, No. 109 / Tuesday, June 8, 2010 / Rules and Regulations 32295 

C. EPA Recommendations to Further 

Improve the Rules 

The TSDs describe additional rule 

revisions that we recommend for the 

next time SCAQMD modifies Rules 218 

and 218.1. These recommendations are 

to: increase the records retention 

requirement to five years in Rule 218, 

remove the de minimus concentration 

option for the relative accuracy 

performance specifications for NOX and 

CO, and evaluate the ppropriateness of 

the de minimus concentration option for 

the relative accuracy performance 

specifications for SO2 and reduced 

sulfur compounds the next time Rule 

218.1 is amended. 

D. Public Comment and Final Action 

As authorized in section 110(k)(3) of 

the Act, EPA is fully approving the 

submitted rules because we believe they 

fulfill all relevant requirements. We do 

not think anyone will object to this 

approval, so we are finalizing it without 

proposing it in advance. However, in 

the Proposed Rules section of this 

Federal Register, we are simultaneously 

proposing approval of the same 

submitted rules. If we receive adverse 

comments by July 8, 2010, we will 

publish a timely withdrawal in the 

Federal Register to notify the public 

that the direct final approval will not 

take effect and we will address the 

comments in a subsequent final action 

based on the proposal. If we do not 

receive timely adverse comments, the 

direct final approval will be effective 

without further notice on August 9, 

2010. This will incorporate these rules 

into the federally enforceable SIP. 

Please note that if EPA receives 

adverse comment on an amendment, 

paragraph, or section of this rule and if 

that provision may be severed from the 

remainder of the rule, EPA may adopt 

as final those provisions of the rule that 

are not the subject of an adverse 

comment. 

III. Statutory and Executive Order 

Reviews 

Under the Clean Air Act, the 

Administrator is required to approve a 

SIP submission that complies with the 

provisions of the Act and applicable 

Federal regulations. 42 U.S.C. 7410(k); 

40 CFR 52.02(a). Thus, in reviewing SIP 

submissions, EPA’s role is to approve 

State choices, provided that they meet 

the criteria of the Clean Air Act. 

Accordingly, this action merely 

approves State law as meeting Federal 

requirements and does not impose 

additional requirements beyond those 

imposed by State law. For that reason, 

this action: 

• Is not a ‘‘significant regulatory 

action’’ subject to review by the Office 

of Management and Budget under 

Executive Order 12866 (58 FR 51735, 

October 4, 1993); 

• Does not impose an information 

collection burden under the provisions 

of the Paperwork Reduction Act (44 

U.S.C. 3501 et seq.); 

• Is certified as not having a 

significant economic impact on a 

substantial number of small entities 

under the Regulatory Flexibility Act (5 

U.S.C. 601 et seq.); 

• Does not contain any unfunded 

mandate or significantly or uniquely 

affect small governments, as described 

in the Unfunded Mandates Reform Act 

of 1995 (Pub. L. 104–4); 

• Does not have Federalism 

implications as specified in Executive 

Order 13132 (64 FR 43255, August 10, 

1999); 

• Is not an economically significant 

regulatory action based on health or 

safety risks subject to Executive Order 

13045 (62 FR 19885, April 23, 1997); 

• Is not a significant regulatory action 

subject to Executive Order 13211 (66 FR 

28355, May 22, 2001); 

• Is not subject to requirements of 

Section 12(d) of the National 

Technology Transfer and Advancement 

Act of 1995 (15 U.S.C. 272 note) because 

application of those requirements would 

be inconsistent with the Clean Air Act; 

and 

• Does not provide EPA with the 

discretionary authority to address, as 

appropriate, disproportionate human 

health or environmental effects, using 

practicable and legally permissible 

methods, under Executive Order 12898 

(59 FR 7629, February 16, 1994). 

In addition, this rule does not have 

tribal implications as specified by 

Executive Order 13175 (65 FR 67249, 

November 9, 2000), because the SIP is 

not approved to apply in Indian country 

located in the State, and EPA notes that 

it will not impose substantial direct 

costs on tribal governments or preempt 

tribal law.

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Final rule. 

SUMMARY: This action announces the 

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 (SDWA) 

authorizes EPA to approve the use of 

alternative testing methods through 

publication in the Federal Register. EPA 

is using this streamlined authority to 

make 12 additional methods available 

for analyzing drinking water samples 

required by regulation. 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 June 8, 

2010.

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 SDWA may also 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. Categories and entities that 

may ultimately be affected by this action 

include: 

Category Examples of potentially regulated entities NAICS1

II. Background 

A. What is the purpose of this action? 

In this action, EPA is approving 12 

analytical methods for determining 

contaminant concentrations in 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. 

The new methods are listed in appendix 

A to subpart C of part 141 and on EPA’s 

drinking water methods Web site at 

http://www.epa.gov/safewater/methods/ 

analyticalmethods_expedited.html. 

This action also includes the full text 

of three tables in Appendix A to Subpart 

C of Part 141. The tables do not include 

any new method approvals. EPA 

inadvertently deleted two table columns 

in the November 10, 2009, Federal 

Register notice (74 FR 57908) (USEPA 

2009b). The corrected tables are titled: 

• Alternative Testing Methods for 

Disinfectant Residuals Listed at 40 CFR 

141.74(a)(2), 

• Alternative Testing Methods for 

Contaminants Listed at 40 CFR 

141.131(b)(1), and 

• Alternative Testing Methods for 

Disinfectant Residuals Listed at 40 CFR 

141.131(c)(1). 

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 

12 additional methods available for 

determining contaminant 

concentrations in 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 equally 

effective as one or more of the testing 

methods already established in the 

regulations for those contaminants. 

Section 1401(1) states that the newly 

approved methods ‘‘shall be treated as 

an alternative for public water systems 


srobinson on DSKHWCL6B1PROD with RULES
Federal Register / Vol. 75, No. 109 / Tuesday, June 8, 2010 / Rules and Regulations 32297 

to the quality control and testing 

procedures listed in the regulation.’’ 

Accordingly, this action makes these 

additional (and optional) 12 analytical 

methods legally available 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 

this Federal Register. 

EPA described this expedited 

methods approval process in an April 

10, 2007, Federal Register notice (72 FR 

17902) (USEPA 2007) and announced 

its intent to begin using the process. 

EPA published the first set of approvals 

in a June 3, 2008, Federal Register 

notice (73 FR 31616) (USEPA 2008) and 

added appendix A to 40 CFR part 141, 

subpart C. Additional methods were 

added to appendix A to subpart C in an 

August 3, 2009, Federal Register notice 

(74 FR 38348) (USEPA 2009a) and a 

November 10, 2009, Federal Register 

notice (74 FR 57908) (USEPA 2009b). 

Future approvals using this process are 

anticipated. 

III. Summary of Approvals 

EPA is approving 12 methods that are 

equally effective relative to methods 

previously promulgated in the 

regulations. By means of this notice, 

these 12 methods are added to appendix 

A to subpart C of part 141. 

A. Methods Developed by EPA 

EPA Method 557 is a direct-injection, 

ion chromatography, negative-ion 

electrospray ionization, tandem mass 

spectrometry (IC–ESI–MS/MS) method 

for the determination of nine haloacetic 

acids, dalapon, and bromate in finished 

drinking waters (USEPA 2009c). Each 

method analyte is qualitatively 

identified via a unique mass transition, 

and the concentration is calculated 

using the integrated peak area and the 

internal standard technique. 

EPA Method 557 eliminates the labor 

intensive sample preparation steps 

(extraction and derivatization) that are 

required in other methods. It also 

reduces the use of solvents and 

potentially hazardous chemicals. The 

development work for this method is 

described in the method research 

summary (Zaffiro and Zimmerman 

2009). EPA Method 557 has already 

been approved for determining 

haloacetic acids and bromate in 

drinking water (74 FR 57908) (USEPA 

2009b); its approval is being expanded 

in this action to include dalapon. 

The approved methods for dalapon 

are listed at 40 CFR 141.24(e)(1). The 

performance characteristics of EPA 

Method 557 for dalapon were compared 

to the characteristics of approved EPA 

Methods 552.2 (USEPA 1995), 552.3 

(USEPA 2003), and 515.4 (USEPA 

2000). EPA has determined that EPA 

Method 557 is equally effective for 

measuring dalapon as each one of these 

three previously approved methods. The 

basis for this determination is discussed 

in Smith (2010a). Therefore, EPA is 

approving EPA Method 557 for 

determining dalapon in drinking water 

and adding it to the list of approved 

methods in appendix A to subpart C of 

part 141 as an alternative method for 

contaminants listed at 40 CFR 

141.24(e)(1). A copy of EPA Method 557 

can be accessed and downloaded 

directly on-line at http://epa.gov/ 

safewater/methods/ 

analyticalmethods_ogwdw.html. 

B. Methods Developed by Voluntary 

Consensus Standard Bodies (VCSB) 

1. Standard Methods for the 

Examination of Water and Wastewater. 

In Standard Method 6640 B, chlorinated 

acids in drinking water are derivatized 

and analyzed using gas chromatography 

with electron capture detection. The 

method uses the identical sample 

handling protocols, analytical 

conditions, and quality control (QC) 

criteria as EPA Method 515.4 (USEPA 

2000), which is approved for analyzing 

compliance samples for dalapon (40 

CFR 141.24(e)(1)). EPA has determined 

that Standard Method 6640 B, published 

in the 21st edition of Standard Methods 

for the Examination of Water and 

Wastewater (APHA 2005), is equally 

effective relative to EPA Method 515.4 

(Smith 2010b) for the analysis of 

compliance samples for dalapon. EPA 

has also determined that Standard 

Method 6640 B–01 (APHA 2001) is an 

identical on-line version of Standard 

Method 6640 B. Accordingly, EPA is 

approving Standard Method 6640 B and 

Standard Method 6640 B–01 for 

determining dalapon in drinking water 

and adding them to the list of approved 

methods in Appendix A to Subpart C of 

Part 141 as alternative methods for 

contaminants listed at 40 CFR 

141.24(e)(1). The 21st edition can be 

obtained from the American Public 

Health Association (APHA), 800 I Street, 

NW., Washington, DC 20001–3710. 

Standard Method 6640 B–01 is available 

at http://www.standardmethods.org. 

2. ASTM International. EPA 

compared the most recent versions of 

six ASTM International methods for 

radiochemicals in water to the versions 

of those methods that are already 

approved under 40 CFR 141.25(a). 

Changes between the approved version 

and the most recent version of each 

method are summarized in Umbaugh 

(2010). The revisions primarily involve 

editorial changes (i.e., updated 

references, definitions, terminology, and 

reorganization of text). The revised 

methods are the same as the approved 

versions with respect to drinking water 

sample collection and handling 

protocols, sample preparation, 

analytical methodology, and results. 

The QC requirements in the revised 

methods have been expanded and are 

more detailed than in the previous 

versions. EPA has determined that the 

new versions are equally effective 

relative to those cited in the regulation 

(ASTM Methods D3454–97, D2460–97, 

D5174–02, D3649–98a, D4785–00a, and 

D4107–98 (reapproved 2002)) (Umbaugh 

2010). Therefore, EPA is approving the 

use of the six updated ASTM methods 

for radiochemicals listed in the 

following table: 

ASTM Method Contaminant 

D3454–05 (ASTM International 2009a) ................................................................................................................................... Radium-226. 

D2460–07 (ASTM International 2009b) ................................................................................................................................... Radium-226. 

D5174–07 (ASTM International 2009c) ................................................................................................................................... Uranium. 

D3649–06 (ASTM International 2009d) ................................................................................................................................... Radioactive Cesium. 

Radioactive Iodine. 

Gamma emitters. 

D4785–08 (ASTM International 2009e) ................................................................................................................................... Radioactive Iodine. 

Gamma emitters. 

D4107–08 (ASTM International 2009f) .................................................................................................................................... Tritium.

32298 Federal Register / Vol. 75, No. 109 / Tuesday, June 8, 2010 / Rules and Regulations 

As of today’s notice, measurements of 

radiochemicals in drinking water may 

be performed using either one of these 

six methods or one of the methods 

already approved at 40 CFR 141.25(a). 

The six ASTM methods are available 

from ASTM International, 100 Barr 

Harbor Drive, West Conshohocken, PA 

19428–2959 or http://www.astm.org. 

C. Methods Developed by Vendors 

EPA previously approved by 

regulation the following alternative 

methods, which are listed at 40 CFR 

141.21(f)(6), for determining Escherichia 

coli (E. coli) under the Total Coliform 

Rule (TCR): Readycult® (EMD 

Chemicals 2007), Chromocult® (EM 

Science 2000), and Modified ColitagTM

(CPI International 2009). These three 

methods were not approved under the 

Ground Water Rule (GWR) (71 FR 

65574, November 8, 2006) (USEPA 

2006), because they were not evaluated 

by EPA prior to proposal of the GWR. 

However, these methods were evaluated 

under the Alternate Test Procedure 

(ATP) program and EPA determined 

that the methods were equally effective 

for E. coli determination relative to 

Standard Method 9221F (Best 2010), 

published in the 20th edition of 

Standard Methods for the Examination 

of Water and Wastewater (APHA 1998). 

Standard Method 9221F is approved for 

E. coli determination under the GWR 

(40 CFR 141.402(c)(2)). EPA is using 

today’s notice to approve the use of 

Readycult®, Chromocult®, and Modified 

ColitagTM to meet E. coli monitoring 

requirements under GWR and is adding 

them to the list of approved methods in 

appendix A to subpart C of part 141 as 

alternative methods for contaminants 

listed at 40 CFR 141.402(c)(2). 

The 20th edition of Standard Methods 

for the Examination of Water and 

Wastewater (1998) is available from the 

American Public Health Association 

(APHA), 800 I Street, NW., Washington, 

DC 20001–3710. 

The Readycult® test is described in 

the document ‘‘Readycult® Coliforms 

100 Presence/Absence Test for 

Detection and Identification of Coliform 

Bacteria and Escherichia coli in 

Finished Waters, January 2007, Version

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 (optional) testing 

methods available for monitoring under 

SDWA, EPA has concluded that other 

statutes and executive orders generally 

applicable to rulemaking do not apply 

to this approval action.

Federal Emergency Management 

Agency 

44 CFR Part 64 

[Docket ID FEMA–2010–0003; Internal 

Agency Docket No. FEMA–8133] 

Suspension of Community Eligibility 

AGENCY: Federal Emergency 

Management Agency, DHS. 

ACTION: Final rule. 

SUMMARY: This rule identifies 

communities, where the sale of flood 

insurance has been authorized under 

the National Flood Insurance Program 

(NFIP), that are scheduled for 

suspension on the effective dates listed 

within this rule because of 

noncompliance with the floodplain 

management requirements of the 

program. If the Federal Emergency 

Management Agency (FEMA) receives 

documentation that the community has 

adopted the required floodplain 

management measures prior to the 

effective suspension date given in this 

rule, the suspension will not occur and 

a notice of this will be provided by 

publication in the Federal Register on a 

subsequent date. 

DATES: Effective Dates: The effective 

date of each community’s scheduled 

suspension is the third date (‘‘Susp.’’) 

listed in the third column of the 

following tables. 

FOR FURTHER INFORMATION CONTACT: If 

you want to determine whether a 

particular community was suspended 

on the suspension date or for further 

information, contact David Stearrett, 

Mitigation Directorate, Federal 

Emergency Management Agency, 500 C 

Street SW., Washington, DC 20472, 

(202) 646–2953. 

SUPPLEMENTARY INFORMATION: The NFIP 

enables property owners to purchase 

flood insurance which is generally not 

otherwise available. In return, 

communities agree to adopt and 

administer local floodplain management 

aimed at protecting lives and new 

construction from future flooding. 

Section 1315 of the National Flood 

Insurance Act of 1968, as amended, 42 

U.S.C. 4022, prohibits flood insurance 

coverage as authorized under the NFIP, 

42 U.S.C. 4001 et seq.; unless an 

appropriate public body adopts 

adequate floodplain management 

measures with effective enforcement 

measures. The communities listed in 

this document no longer meet that 

statutory requirement for compliance 

with program regulations, 44 CFR part 

59. Accordingly, the communities will 

be suspended on the effective date in 

the third column. As of that date, flood 

insurance will no longer be available in 

the community. However, some of these 

communities may adopt and submit the 

required documentation of legally 

enforceable floodplain management 

measures after this rule is published but 

prior to the actual suspension date. 

These communities will not be 

suspended and will continue their 

eligibility for the sale of insurance. A 

notice withdrawing the suspension of 

the communities will be published in 

the Federal Register. 

In addition, FEMA has identified the 

Special Flood Hazard Areas (SFHAs) in 

these communities by publishing a 

Flood Insurance Rate Map (FIRM). The 

date of the FIRM, if one has been 

published, is indicated in the fourth 

column of the table. No direct Federal 

financial assistance (except assistance 

pursuant to the Robert T. Stafford 

Disaster Relief and Emergency 

Assistance Act not in connection with a 

flood) may legally be provided for 

construction or acquisition of buildings 

in identified SFHAs for communities 

not participating in the NFIP and 

identified for more than a year, on 

FEMA’s initial flood insurance map of 

the community as having flood-prone 

areas (section 202(a) of the Flood 

Disaster Protection Act of 1973, 42 

U.S.C. 4106(a), as amended). This 

prohibition against certain types of 

Federal assistance becomes effective for 

the communities listed on the date 

shown in the last column. The 

Administrator finds that notice and 

public comment under 5 U.S.C. 553(b) 

are impracticable and unnecessary 

because communities listed in this final 

rule have been adequately notified. 

Each community receives 6-month, 

90-day, and 30-day notification letters 

addressed to the Chief Executive Officer 

stating that the community will be 

suspended unless the required 

floodplain management measures are 

met prior to the effective suspension 

date. Since these notifications were 

made, this final rule may take effect 

within less than 30 days. 

National Environmental Policy Act. 

This rule is categorically excluded from 

the requirements of 44 CFR part 10, 

Environmental Considerations. No 

environmental impact assessment has 

been prepared. 

Regulatory Flexibility Act. The 

Administrator has determined that this 

rule is exempt from the requirements of 

the Regulatory Flexibility Act because 

the National Flood Insurance Act of 

1968, as amended, 42 U.S.C. 4022, 

prohibits flood insurance coverage 

unless an appropriate public body 

adopts adequate floodplain management 

measures with effective enforcement 

measures. The communities listed no 

longer comply with the statutory 

requirements, and after the effective 

date, flood insurance will no longer be 

available in the communities unless 

remedial action takes place. 

Regulatory Classification. This final 

rule is not a significant regulatory action 

under the criteria of section 3(f) of 

Executive Order 12866 of September 30, 

1993, Regulatory Planning and Review, 

58 FR 51735. 

Executive Order 13132, Federalism. 

This rule involves no policies that have 

federalism implications under Executive 

Order 13132. 

Executive Order 12988, Civil Justice 

Reform. This rule meets the applicable 

standards of Executive Order 12988. 

Paperwork Reduction Act. This rule 

does not involve any collection of 

information for purposes of the 

Paperwork Reduction Act, 44 U.S.C. 

3501 et seq.
