impact on a substantial number of small 

entities under the Regulatory Flexibility 

Act (5 U.S.C. 601 et seq.). Because this 

rule approves pre-existing requirements 

under State law and does not impose 

any additional enforceable duty beyond 

that required by State law, it 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). This rule also does not 

have Tribal implications because it will 

not have a substantial direct effect on 

one or more Indian Tribes, on the 

relationship between the Federal 

Government and Indian Tribes, or on 

the distribution of power and 

responsibilities between the Federal 

Government and Indian Tribes, as 

specified by Executive Order 13175 (65 

FR 67249, November 9, 2000). This 

action also does not have Federalism 

implications because it does not have 

substantial direct effects on the States, 

on the relationship between the national 

government and the States, or on the 

distribution of power and 

responsibilities among the various 

levels of government, as specified in 

Executive Order 13132 (64 FR 43255, 

August 10, 1999). This action merely 

approves a State rule implementing a 

Federal requirement, and does not alter 

the relationship or the distribution of 

power and responsibilities established 

in the CAA. This rule also is not subject 

to Executive Order 13045 ‘‘Protection of 

Children from Environmental Health 

Risks and Safety Risks’’ (62 FR 19885, 

April 23, 1997), because it approves a 

State rule implementing a Federal 

standard. In reviewing section 111(d)/ 

129 plan submissions, EPA’s role is to 

approve State choices, provided that 

they meet the criteria of the CAA. In this 

context, in the absence of a prior 

existing requirement for the State to use 

voluntary consensus standards (VCS), 

EPA has no authority to disapprove a 

111(d)/129 plan submission for failure 

to use VCS. It would thus be 

inconsistent with applicable law for 

EPA, when it reviews a 111(d)/129 plan 

submission, to use VCS in place of a 

111(d)/129 plan submission that 

otherwise satisfies the provisions of the 

CAA. Thus, the requirements of section 

12(d) of the National Technology 

Transfer and Advancement Act of 1995 

(15 U.S.C. 272 note) do not apply. This 

rule does not impose an information 

collection burden under the provisions 

of the Paperwork Reduction Act of 1995 

(44 U.S.C. 3501 et seq.). 

B. Submission to Congress and the 

Comptroller General 

The Congressional Review Act, 5 

U.S.C. 801 et seq., as added by the Small 

Business Regulatory Enforcement 

Fairness Act of 1996, generally provides 

that before a rule may take effect, the 

agency promulgating the rule must 

submit a rule report, which includes a 

copy of the rule, to each House of the 

Congress and to the Comptroller General 

of the United States. EPA will submit a 

report containing this rule and other 

required information to the U.S. Senate, 

the U.S. House of Representatives, and 

the Comptroller General of the United 

States prior to publication of the rule in 

the Federal Register. This rule is not a 

‘‘major rule’’ as defined by 5 U.S.C. 

804(2). 

C. Petitions for Judicial Review 

Under section 307(b)(1) of the Clean 

Air Act, petitions for judicial review of 

this action must be filed in the United 

States Court of Appeals for the 

appropriate circuit by October 2, 2009. 

Filing a petition for reconsideration by 

the Administrator of this final rule does 

not affect the finality of this rule for the 

purposes of judicial review nor does it 

extend the time within which a petition 

for judicial review may be filed, and 

shall not postpone the effectiveness of 

such rule or action. Parties with 

objections to this direct final rule are 

encouraged to file a comment in 

response to the parallel notice of 

proposed rulemaking for this action 

published in the proposed rules section 

of today’s Federal Register, rather than 

file an immediate petition for judicial 

review of this direct final rule, so that 

EPA can withdraw this direct final rule 

and address the comment in the 

proposed rulemaking. This action, 

approving the submitted West Virginia 

HMIWI plan revision, may not be 

challenged later in proceedings to 

enforce its requirements. (See section 

307(b)(2).)

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 six 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

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 six 

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 in 40 CFR 141 

and on EPA’s drinking water methods 

Web site at http://www.epa.gov/ 

safewater/methods/ 

analyticalmethods_expedited.html. 

B. What Is the Basis for This Action? 

When EPA determines 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 six 

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 as 

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 


sroberts on DSKD5P82C1PROD with RULES
38350 Federal Register / Vol. 74, No. 147 / Monday, August 3, 2009 / Rules and Regulations 

an alternative for public water systems 

to the quality control and testing 

procedures listed in the regulation.’’ 

Accordingly, this action makes these 

additional (and optional) six 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. This action adds six 

additional methods to Appendix A to 

Subpart C. 

III. Summary of Approvals 

EPA is approving six methods that are 

equally effective relative to methods 

previously promulgated in the 

regulations. By means of this notice, 

these six methods are added to 

Appendix A of 40 CFR Part 141, Subpart 

C. For convenience of the reader, the 

revised Appendix A in its entirety is 

shown below. However, the only change 

made to Appendix A through this action 

is the inclusion of these six additional 

methods as described in this preamble. 

A. Methods Developed by EPA 

EPA Method 524.3, Version 1.0. This 

is a gas chromatography/mass 

spectrometry (GC/MS) method for the 

determination of purgeable organic 

compounds in finished drinking waters. 

The method analytes are purged from 

the water sample using helium and 

trapped on a sorbent material. After 

purging, the trap is heated and back 

flushed with helium to transfer the 

analytes to a capillary GC column. 

Compounds eluting from the GC are 

directed into a mass spectrometer for 

mass analysis and detection. The 

analytes are identified by comparing the 

acquired mass spectra and retention 

times to reference spectra and retention 

times for calibration standards acquired 

under identical GC/MS conditions. The 

concentration of each target analyte is 

calculated using the internal standard 

technique and response curves obtained 

via procedural calibration. The 

expansion of the method to include the 

option of selective ion monitoring 

makes this method sufficiently sensitive 

to measure dibromochloropropane 

(DBCP) and ethylene dibromide (EDB) at 

the concentrations required for drinking 

water compliance monitoring. 

EPA Method 524.3 is an updated 

version of EPA Method 524.2, Revision 

4.1 (USEPA 1995a), which is currently 

approved for analyses of compliance 

samples for 21 volatile organic 

contaminants and total trihalomethanes. 

The method development work is 

described in the method research 

summary (Zaffiro et al. 2009). The 

advantages of the new method include: 

• Use of maleic acid, a common food 

preservative, to preserve samples, 

eliminating the requirement to ship a 

hazardous reagent (hydrochloric acid) to 

the field; 

• Incorporation of features that allow 

users to take advantage of modern 

instrumentation to improve speed and 

data quality; 

• Increased flexibility in selection of 

method operating parameters; and 

• Addition of Method 524.3 as an 

approved method for DBCP and EDB. 

Approved methods for volatile 

organic contaminants and total 

trihalomethanes are listed at 40 CFR 

141.24(e). EPA Methods 502.2; Revision 

2.1 (USEPA 1995b) and 524.2; Revision 

4.1 (USEPA 1995a) are approved for 

benzene; carbon tetrachloride; 

chlorobenzene; 1,2-dichlorobenzene; 

1,4-dichlorobenzene; 1,2- 

dichloroethane; cis-dichloroethylene; 

trans-dichloroethylene; 

dichloromethane; 1,2-dichloropropane; 

ethylbenzene; styrene; 

tetrachloroethylene; 1,1,1- 

trichloroethane; trichloroethylene; 

toluene; 1,2,4-trichlorobenzene; 1,1- 

dichloroethylene; 1,1,2-trichlorethane; 

vinyl chloride; xylenes (total—measured 

as sum of o-xylene; m-xylene and pxylene); and total trihalomethanes (sum 

of chloroform; bromodichloromethane; 

dibromochloromethane; and 

bromoform). EPA Method 551.1 (USEPA 

1995c) is approved for carbon 

tetrachloride; tetrachloroethylene; 1,1,1- 

trichloroethane; trichloroethylene; EDB; 

DBCP; and total trihalomethanes. EPA 

Method 504.1, Revision 1.1 (USEPA 

1995d) is approved for EDB and DBCP. 

Approved methods for total 

trihalomethanes are also listed at 40 

CFR 141.131(b)(1). For each of the 24 

contaminants, the performance 

characteristics of EPA Method 524.3 

were compared to the characteristics of 

each of the methods currently listed in 

the regulations as approved for that 

contaminant (Munch 2009). EPA has 

determined that, for each of the 24 

contaminants, EPA Method 524.3 is 

equally as effective for measuring the 

contaminant as the methods currently 

listed in the regulations as approved for 

that contaminant. The basis for this 

determination is discussed in Munch 

2009. EPA is therefore approving use of 

Method 524.3 for the above named 24 

contaminants when analyzing drinking 

water compliance samples.

B. Methods Developed by Vendors 

1. Mitchell Method M5271. Mitchell 

Method M5271 (Mitchell 2009a) uses 

laser nephelometry to measure turbidity 

in drinking water. The method is based 

on a comparison of the intensity of light 

scattered by the sample under defined 

conditions with the intensity of light 

scattered by a standard reference 

suspension. Readings are made using an 

on-line laser nephelometer with the 

following design criteria: 

• Laser light source is monochromatic 

operated at a nominal wavelength of 650 

± 30nm; 

• Incident radiation and any 

convergence does not exceed ± 1.5 

degrees in the measurement area; 

• Distance traversed by incident light 

and scattered light does not exceed 

10cm; 

• Detector/light receiver is centered at 

90 ± 1.5 degrees to the incident light 

path and the light cone does not exceed 

± 30 degrees from 90 degrees; and 

• Instrument incorporates a bubble 

trap and anti-fog windows. Sensor is 

horizontal and the windows are vertical. 

Windows are immersed in the sample 

stream. 

Four approved methods for turbidity 

are listed at 40 CFR 141.74(a)(1). The 

performance characteristics of Mitchell 

Method M5271 were compared to the 

performance characteristics of approved 

EPA Method 180.1 (USEPA 1993a). The 

validation study report (Mitchell 2008a) 

summarizes the results obtained from 

the turbidimeters placed in series at 

three different public water systems. 

One water system used ground water 

and the other two plants used surface 

water sources. Measurements included 

at least one filter backwash at each of 

the surface water plants. 

EPA has determined that the Mitchell 

Method M5271 is equally effective 

relative to EPA Method 180.1 that is 

already promulgated in the regulations 

at 40 CFR 141.74(a)(1). The basis for this 

determination is discussed in 

Wendelken 2009a. Therefore, EPA is 

approving the Mitchell Method M5271 

for determining turbidity in drinking

2. Mitchell Method M5331. Mitchell 

Method M5331 (Mitchell 2009b) uses 

light-emitting diode (LED) 

nephelometry to measure turbidity in 

drinking water. The method is based on 

a comparison of the intensity of light 

scattered by the sample under defined 

conditions with the intensity of light 

scattered by a standard reference 

suspension. Readings are made using an 

on-line LED nephelometer with the 

following design criteria: 

• LED light source is monochromatic 

operated at a nominal wavelength of 525 

± 15nm; 

• Incident radiation and any 

convergence does not exceed ± 1.5 

degrees in the measurement area; 

• Distance traversed by incident light 

and scattered light does not exceed 

10cm; 

• Detector/light receiver is centered at 

90 ± 1.5 degrees to the incident light 

path and the light cone does not exceed 

± 30 degrees from 90 degrees; and 

• Instrument incorporates a bubble 

trap and anti-fog windows. Sensor is 

horizontal and the windows are vertical. 

Windows are immersed in the sample 

stream. 

Four approved methods for turbidity 

are listed at 40 CFR 141.74(a)(1). The 

performance characteristics of Mitchell 

Method M5331 were compared to the 

performance characteristics of approved 

EPA Method 180.1 (USEPA 1993a). The 

validation study report (Mitchell 2008b) 

summarizes the results obtained from 

the turbidimeters placed in series at 

three different public water systems. 

One water system used ground water 

and the other two plants used surface 

water sources. Measurements included 

at least one filter backwash at each of 

the surface water plants. 

EPA has determined that the Mitchell 

Method M5331 is equally effective 

relative to EPA Method 180.1 that is 

already promulgated in the regulations 

at 40 CFR 141.74(a)(1). The basis for this 

determination is discussed in 

Wendelken 2009b. Therefore, EPA is 

approving it for determining turbidity in 

drinking water. A copy of the method 

can be downloaded from NEMI at

3. Orion Method AQ4500. Thermo 

Scientific’s Orion Method AQ4500 

(Thermo Scientific 2009) uses LED 

nephelometry to measure turbidity in 

drinking water. The method is based on 

a comparison of the intensity of light 

scattered by the sample at 90 degrees to 

the beam path with the intensity of light 

scattered by a standard reference 

suspension. Readings are made using a 

portable LED nephelometer with the 

following design criteria: 

• White LED light source emits 

broadband light having peak intensities 

in the 400nm to 600nm range; 

• Distance traversed by incident light 

and scattered light does not exceed 

10cm; 

• Detector/light receiver is centered at 

90 degrees to the incident light path and 

the light cone does not exceed ± 30 

degrees from 90 degrees. The detector 

has spectral peak response between 

400nm and 600nm; 

• Pulsed light allows for synchronous 

detection, a technique by which 

ambient stray light leakage, as well as 

other electronic induced errors, are 

effectively cancelled out; and 

• Color compensation is achieved 

using a dual-beam system with two 

photo detectors. 

Four approved methods for turbidity 

are listed at 40 CFR 141.74(a)(1). The 

performance characteristics of Thermo 

Scientific’s Orion Method AQ4500 were 

compared to the performance 

characteristics of EPA Method 180.1 

(USEPA 1993a) listed at 40 CFR 

141.74(a)(1) for measurement of 

turbidity. Two rounds of testing were 

conducted (Wendelken 2009c). The first 

was an ASTM round robin study 

comparing results from analyses of 28 

samples of various types using 

turbidimeters with tungsten filament 

light sources as specified in EPA 

Method 180.1 and white LEDs as 

specified in Thermo Scientific Orion 

Method AQ4500. A second study 

involved demonstration of performance 

at turbidities below 2 nephelometric 

turbidity units. 

EPA has determined that Thermo 

Scientific’s Orion Method AQ4500 is 

equally effective relative to EPA Method 

180.1, which is already promulgated in 

the regulations at 40 CFR 141.74(a)(1). 

The basis for this determination is 

discussed in Wendelken 2009c. 

Therefore, EPA is approving Method 

AQ4500 for the measurement of 

turbidity in drinking water. A copy of 

the method can be downloaded from

4. Systea Easy (1-Reagent). Systea 

Scientific, LLC’s Systea Easy (1-Reagent) 

Nitrate Method uses automated discreet 

analysis by spectrophotometry to 

determine concentrations of nitrate and 

nitrite combined or individually in 

drinking water. The method involves 

the following steps: 

• Reduction of nitrate in a sample to 

nitrite using a non-hazardous 

proprietary reagent; 

• Diazotizing the nitrite originally in 

the sample plus the reduced nitrate with 

sulfanilamide followed by coupling 

with N-(1-napthyl)ethylenediamine 

dihydrochloride under acidic 

conditions to form a highly colored azo 

dye; 

• Colorimetric determination in 

which the absorbance of color at 546nm 

is directly proportional to the 

concentration of the nitrite plus the 

reduced nitrate in the sample; 

• Measurement of nitrite individually 

by analysis of the sample while 

eliminating the reduction step; and 

• Subtraction of the nitrite value from 

that of the combined nitrate plus nitrite 

value to determine nitrate individually. 

Approved methods for nitrate and 

nitrite are listed at 40 CFR 141.23(k)(1). 

An inter-laboratory study (Systea 

Scientific, LLC. 2008) was conducted to 

compare the performance characteristics 

of the Systea Easy (1-Reagent) Nitrate 

Method to the characteristics of the EPA 

Method 353.2 (USEPA 1993b) and 

Standard Method 4500–NO3

¥ F–00 

(APHA 1997), which are listed at 40 

CFR 141.23(k)(1) for nitrate and nitrite. 

Ten laboratories analyzed a variety of 

sample matrices using approved 

methods. The samples were also 

analyzed using the Systea Easy (1- 

Reagent) Nitrate Method. 

EPA has determined that the Systea 

Easy (1-Reagent) Nitrate Method is 

equally effective relative to EPA Method 

353.2 and Standard Method 4500–NO3

¥

F–00, which are already promulgated in 

the regulations. The basis for this 

determination is discussed in 

Wendelken 2009d. The method is a 

‘‘green’’ alternative to other approved 

methods, which use cadmium, a known 

carcinogen, for the reduction of nitrate 

to nitrite. EPA is approving this method 

for determining nitrate and nitrite 

concentrations in drinking water to 

comply with 40 CFR 141.23.

5. Method ME355.01. ‘‘Determination 

of Cyanide in Drinking Water by GC/MS 

Headspace’’ (Eaton 2009) uses direct 

headspace injection after acidification 

followed by Gas Chromatography/Mass 


sroberts on DSKD5P82C1PROD with RULES
38352 Federal Register / Vol. 74, No. 147 / Monday, August 3, 2009 / Rules and Regulations 

Spectrometry (GC/MS) to determine the 

concentration of cyanide, as free 

cyanide, in drinking water. The method 

involves the following steps: 

• Acidification of the sample; 

• Heating the sample to 60 degrees 

Celsius with agitation; 

• Direct injection of 1 milliliter of 

headspace onto the nitrogen cooled 

cryotrap; and 

• Analysis using temperature 

programmed GC/MS. 

The performance characteristics of 

Method ME355.01 were determined in 

three laboratories by replicate analyses 

of fortified samples (Wendelken 2009e). 

The results were compared to the 

characteristics of EPA Method 335.4 

(USEPA 1993c) and Standard Method 

4500–CN¥ F–99 (APHA 1999) listed at 

40 CFR 141.23(k)(1) for cyanide. EPA 

has determined that Method ME355.01 

is equally effective relative to each of 

these two methods. The basis for this 

determination is discussed in 

Wendelken 2009e. Therefore, EPA is 

approving this method for determining 

cyanide concentrations in drinking 

water to comply with 40 CFR 141.23. 

Method ME335.01 can be downloaded 

from NEMI at http://www.nemi.gov or

Testing Laboratory, 221 State Street, 

Augusta, ME 04333, Phone: (207) 187– 

2727. 

IV. Statutory and Executive Order 

Reviews 

As noted above, 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.

DEPARTMENT OF HOMELAND 

SECURITY 

Federal Emergency Management 

Agency 

44 CFR Part 64 

[Docket ID FEMA–2008–0020; Internal 

Agency Docket No. FEMA–8085] 

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
