National Primary Drinking Water Regulations: Analytical Method 
for Uranium

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is taking final 
action to approve the use of three additional analytical methods for 
compliance determinations of uranium in drinking water. These methods 
use an inductively coupled plasma mass spectrometry (ICP-MS) technology 
that has gained wide acceptance in the analytical community. EPA 
believes that ICP-MS analytical methods could be more cost-effective, 
less labor-intensive or more sensitive than some of the technologies 
previously approved in the December 2000 Radionuclides rule. (65 FR 
76708) This rule does not withdraw approval of any previously approved 
monitoring methods for uranium.

DATES: This rule is effective on August 25, 2004. The incorporation by 
reference of certain publications listed in this rule is approved by 
the Director of the Federal Register as of August 25, 2004.

    This table is not intended to be exhaustive, but rather provides a 
guide for readers regarding entities likely to be regulated by this 
action. This table lists the types of entities that EPA is now aware 
could potentially be regulated by this action. Other types of entities 
not listed in the table could also be regulated. To determine whether 
your facility is regulated by this action, you should carefully examine 
the applicability criteria in Sec.  141.66 of title 40 of the Code of 
Federal Regulations. If you have questions regarding the applicability 
of this action to a particular entity, consult the person listed in the 
preceding FOR FURTHER INFORMATION CONTACT section.

II. What Is EPA's Statutory Authority and Background for This Final 
Rule?

    The Safe Drinking Water Act (SDWA), as amended in 1996, requires 
EPA to promulgate national primary drinking water regulations (NPDWRs) 
that specify maximum contaminant levels (MCLs) or treatment techniques 
for drinking water contaminants (SDWA section 1412 (42 U.S.C. 300g-1)). 
NPDWRs apply to public water systems pursuant to SDWA section 1401 (42 
U.S.C. 300f(1)(A)). According to SDWA section 1401(1)(D), NPDWRs 
include ``criteria and procedures to assure a supply of drinking water 
which dependably complies with such maximum contaminant levels; 
including accepted methods for quality control and testing 
procedures.'' In addition, SDWA section 1445(a) authorizes the 
Administrator to establish regulations for monitoring to assist in 
determining whether persons are acting in compliance with the 
requirements of the SDWA. EPA's promulgation of analytical methods is 
authorized under these sections of the SDWA, as well as the general 
rulemaking authority in SDWA section 1450(a), (42 U.S.C. 300j-9(a)). 
The action proposed herein would affect CWSs. CWSs are a subset of 
public water systems. (40 CFR 141.2)
    On December 7, 2000 (65 FR 76708), EPA published a final 
radionuclides rule in the Federal Register that included monitoring 
requirements and a MCL of 30 micrograms per liter (30 microg/L) for 
uranium that took effect in December 2003. In the preamble to the 
December 2000 rule, EPA noted that several commenters asked EPA to 
consider the approval of compliance monitoring methods that use an 
inductively coupled plasma mass spectrometry (ICP-MS) technology. (65 
FR 76724) These commenters suggested that ICP-MS analytical methods 
could be more cost-effective, less labor-intensive or more sensitive 
than some of the technologies approved in the December 2000 rule. In 
response to these comments, EPA stated that the Agency was reviewing 
ICP-MS technology for possible proposal in a future rulemaking.
    EPA proposed the approval of three methods that use ICP-MS 
technology for compliance determinations of uranium in drinking water 
in the Federal Register on June 2, 2004 (69 FR 31068). Specifically, 
EPA proposed the approval of ICP-MS methods published by EPA, ASTM 
International, and the Standard Methods (SM) Committee (EPA 200.8, ASTM 
D5673-03, and SM 3125). The proposed approval of the three ICP-MS 
methods did not, and does not, affect approval of the 15 methods 
already specified at 40 CFR 141.25(a) for compliance determinations of 
uranium.
    EPA has completed its review of the comments received on the June 
2, 2004, proposal and is today approving the three ICP-MS methods 
described above. The methods are very similar and are published by EPA, 
American Society for Testing and Materials International (ASTM), and 
the Standard Methods (SM) Committee. The methods are EPA 200.8, ASTM 
D5673-03, and SM 3125.

III. What Is EPA Doing Today?

    EPA is taking final action to approve the use of three additional 
analytical methods for compliance determinations of uranium in drinking 
water. These methods use an ICP-MS technology that has gained wide 
acceptance in the analytical community. Method EPA 200.8 was published 
by EPA in 1994; method ASTM D5673-03 was published by ASTM 
International in 2003; and SM 3125 was published by the Standard 
Methods Committee in 1998. In today's action, EPA is approving the use 
of these ICP-MS methods for compliance determinations of uranium in 
drinking water.
    This rule will be effective on August 25, 2004. Making this rule 
effective immediately is in the public interest. Because use of EPA-
approved analytical methods is required, approval of these relatively 
inexpensive methods is expected to garner considerable cost savings. It 
is EPA's expectation that reducing the burdens on community water 
systems will encourage compliance with testing requirements themselves. 
Hence, today's rule expanding the limited number of available test 
methods for compliance determinations of uranium in drinking water 
should provide considerable relief to community water systems and EPA 
finds that it has good cause to make this rule effective immediately.

IV. Summary of ICP-MS Technology

    EPA reviewed ICP-MS methods published by EPA, ASTM International, 
and the Standard Methods Committee. In each of these methods, sample 
material in solution is introduced by pneumatic nebulization into a 
radiofrequency plasma where energy

[[Page 52178]]

transfer processes cause desolvation, atomization, and ionization. The 
ions are extracted from the plasma through a differentially pumped 
vacuum interface and separated on the basis of their mass-to-charge 
ratio by a quadrupole mass spectrometer having a minimum resolution 
capability of one atomic mass unit peak width at five percent peak 
height. The ions transmitted through the quadrupole are detected by an 
electron multiplier or Faraday detector and the ion information 
processed by a data handling system. The sensitivity of each ICP-MS 
method for compliance determinations of uranium in drinking water is 
acceptable and is sensitive enough to detect at less than one part per 
billion (1 ug/L). The uranium MCL is 30 ug/L.
    EPA reviewed each of these methods for performance and 
applicability to compliance determinations of uranium in drinking 
water. Three of these methods, EPA 200.8, ASTM D5673-03, and SM 3125, 
have acceptable performance and are otherwise suitable for compliance 
determinations of uranium in drinking water. Method EPA 200.8 was 
published by EPA in 1994; method ASTM D5673-03 was published by ASTM 
International in 2003; and SM 3125 was published by the Standard 
Methods Committee in 1998. In today's action, EPA is approving the use 
of these ICP-MS methods for compliance determinations of uranium in 
drinking water. EPA is taking this action in response to stakeholder 
requests.
    EPA is not, in today's action, approving the use of these methods 
for any other purposes. EPA notes that EPA 200.8 was approved for 
compliance determinations of several regulated metals in drinking water 
on December 5, 1994. (59 FR 62456) EPA also recognizes that the other 
two ICP-MS methods approved through today's action for determination of 
uranium may also be applicable to monitoring for other drinking water 
contaminants. Although the analytical scope of ASTM D5673-03 and SM 
3125 extends beyond uranium, these two methods were not published until 
2003 and 1998, respectively. In a later rulemaking, EPA may consider 
extending the use of ASTM D5673-03 and SM 3125 to compliance 
determinations of other regulated metals.
    Like fluorometric and laser phosphorimetry methods, ICP-MS measures 
uranium mass only; therefore, all caveats discussed in the December 
2000 Radionuclides Rule on using mass methods to determine 
contributions to gross alpha also apply. (65 FR 76724)
    Today's final rule does not affect approval of the 15 methods 
already specified at 40 CFR 141.25(a) for compliance determinations of 
uranium.

V. Response to Comment

    EPA received a somewhat ambiguous letter during the public comment 
period of the proposed rule (69 FR 31068) that was published in the 
Federal Register on June 2, 2004. The Agency has withdrawn the direct 
final rule because of this letter. The commenter did not explicitly 
object to the approval of any of the three ICP-MS methods; however, he 
did seek clarification regarding the relationship of certain laboratory 
certification measures to these analytical methods. Specifically, the 
commenter noted that ``in the ``Manual for the Certification of 
Laboratories Analyzing Drinking Water'' all methods for uranium are 
addressed in the Radiochemistry chapter even though not all the methods 
are radiochemical based, e.g., fluorometric and laser phosphorimetry. 
Unfortunately, the final and proposed actions don't address if the 
Radiochemistry chapter should also be applied to the ICP-MS 
determination of uranium.''
    While the Agency does not believe the comment is directly relevant 
to the merits of the ICP-MS method itself, the Agency chooses to 
address it. The cited laboratory certification document is an EPA 
publication that States may use as a reference in developing programs 
for the certification of laboratories to conduct compliance monitoring 
under the Safe Drinking Water Act. The Agency believes that it is 
likely that States will apply the Radiochemistry chapter to the use of 
the ICP-MS methods approved in today's final rule, though that decision 
rests with the States.
    The commenter also cited an alternate test procedures (ATP) 
Protocol for Organic and Inorganic Analytes. This protocol (EPA 821-B-
98-002) was published by EPA in March 1999. The commenter stated that 
he believes that it is ``unclear from the final and proposed actions if 
any of the indicated methods are being designated as the reference 
method for ATP purposes.''
    The ATP protocol applies only to the comparison of alternate test 
procedures for the determination of chemicals. This protocol does not 
apply to comparison of alternate test procedures for the determination 
of radionuclides, and EPA has not developed a protocol for 
radionuclides.

VI. Statutory and Executive Order Reviews

A. Executive Order 12866: Regulatory Planning and Review

    Under Executive Order 12866, [58 FR 51735 (October 4, 1993)] the 
Agency must determine whether the regulatory action is ``significant'' 
and therefore subject to OMB review and the requirements of the 
Executive Order. The Order defines ``significant regulatory action'' as 
one that is likely to result in a rule that may:
    (1) Have an annual effect on the economy of $100 million or more or 
adversely affect in a material way the economy, a sector of the 
economy, productivity, competition, jobs, the environment, public 
health or safety, or State, local, or tribal governments or 
communities;
    (2) Create a serious inconsistency or otherwise interfere with an 
action taken or planned by another agency;
    (3) Materially alter the budgetary impact of entitlements, grants, 
user fees, or loan programs or the rights and obligations of recipients 
thereof; or
    (4) Raise novel legal or policy issues arising out of legal 
mandates, the President's priorities, or the principles set forth in 
the Executive Order.
    It has been determined that this rule is not a ``significant 
regulatory action'' under the terms of Executive Order 12866 and is 
therefore not subject to OMB review.

B. Paperwork Reduction Act

    This action does not impose an information collection burden under 
the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. 
This action does not impose any new requirements; rather, it approves 
three additional voluntary analytical methods for compliance 
determinations of uranium in drinking water.
    Burden means the total time, effort, or financial resources 
expended by persons to generate, maintain, retain, or disclose or 
provide information to or for a Federal agency. This includes the time 
needed to review instructions; develop, acquire, install, and utilize 
technology and systems for the purposes of collecting, validating, and 
verifying information, processing and maintaining information, and 
disclosing and providing information; adjust the existing ways to 
comply with any previously applicable instructions and requirements; 
train personnel to be able to respond to a collection of information; 
search data sources; complete and review the collection of information; 
and transmit or otherwise disclose the information.

[[Page 52179]]

    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. The OMB control numbers for EPA's 
regulations in 40 CFR are listed in 40 CFR part 9.

C. Regulatory Flexibility Act

    The Regulatory Flexibility Act (RFA) generally requires an agency 
to prepare a regulatory flexibility analysis of any rule subject to 
notice and comment rulemaking requirements under the Administrative 
Procedure Act or any other statute unless the agency certifies that the 
rule will not have a significant economic impact on a substantial 
number of small entities. Small entities include small businesses, 
small organizations, and small government jurisdictions.
    The RFA provides default definitions for each type of small entity. 
Small entities are defined as: (1) A small business as defined by the 
Small Business Administration's (SBA) regulations at 13 CFR 121.201; 
(2) a small governmental jurisdiction that is a government of a city, 
county, town, school district or special district with a population of 
less than 50,000; and (3) a small organization that is any ``not-for-
profit enterprise which is independently owned and operated and is not 
dominant in its field.'' However, the RFA also authorizes an agency to 
use alternative definitions for each category of small entity, ``which 
are appropriate to the activities of the agency'' after proposing the 
alternative definition(s) in the Federal Register and taking comment. 5 
U.S.C. secs. 601(3)-(5). In addition, to establish an alternative small 
business definition, agencies must consult with the Small Business 
Administration's (SBA's) Chief Counsel for Advocacy.
    For purposes of assessing the impacts of today's rule on small 
entities, EPA considered small entities to be public water systems 
serving 10,000 or fewer persons. This is the cut-off level specified by 
Congress in the 1996 Amendments to the Safe Drinking Water Act for 
small system flexibility provisions. In accordance with the RFA 
requirements, EPA proposed using this alternative definition in the 
Federal Register (63 FR 7620, February 13, 1998), requested public 
comment, consulted with the Small Business Administration (SBA), and 
finalized the alternative definition for all future drinking water 
regulations in the Consumer Confidence Reports regulation (63 FR 44511, 
August 19, 1998). As stated in that Final Rule, the alternative 
definition would be applied to this regulation as well.
    This final rule imposes no cost on any entities over and above 
those imposed by the final Radionuclides Rule. (65 FR 76708) This 
action merely allows three additional analytical methods for compliance 
determinations of uranium in drinking water. The use of these methods 
is voluntary because drinking water systems can continue to use the 
existing approved methods.
    After considering the economic impacts of today's final rule on 
small entities, I certify that this action will not have a significant 
economic impact on a substantial number of small entities. The small 
entities directly regulated by this final rule are public water systems 
serving 10,000 or fewer persons. We have determined that no number of 
small entities will be impacted by this voluntary action because 
drinking water systems can continue to use the existing approved 
methods.

D. Unfunded Mandates Reform Act

    Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), Pub. 
L. 104-4, establishes requirements for Federal agencies to assess the 
effects of their regulatory actions on State, local, and tribal 
governments and the private sector. Under section 202 of the UMRA, EPA 
generally must prepare a written statement, including a cost-benefit 
analysis, for proposed and final rules with ``Federal mandates'' that 
may result in expenditures to State, local, and tribal governments, in 
the aggregate, or to the private sector, of $100 million or more in any 
one year. Before promulgating an EPA rule for which a written statement 
is needed, section 205 of the UMRA generally requires EPA to identify 
and consider a reasonable number of regulatory alternatives and adopt 
the least costly, most cost-effective or least burdensome alternative 
that achieves the objectives of the rule. The provisions of section 205 
do not apply when they are inconsistent with applicable law. Moreover, 
section 205 allows EPA to adopt an alternative other than the least 
costly, most cost-effective or least burdensome alternative if the 
Administrator publishes with the final rule an explanation why that 
alternative was not adopted. Before EPA establishes any regulatory 
requirements that may significantly or uniquely affect small 
governments, including tribal governments, it must have developed under 
section 203 of the UMRA a small government agency plan. The plan must 
provide for notifying potentially affected small governments, enabling 
officials of affected small governments to have meaningful and timely 
input in the development of EPA regulatory proposals with significant 
Federal intergovernmental mandates, and informing, educating, and 
advising small governments on compliance with the regulatory 
requirements.
    Today's rule contains no Federal mandates (under the regulatory 
provision of Title II of the UMRA) for State, local, or tribal 
governments or the private sector. The rule imposes no enforceable duty 
on any State, local, or tribal governments or the private sector. It 
merely provides drinking water utilities with three additional 
voluntary analytical methods to use to meet existing monitoring 
requirements. Thus, today's rule is not subject to the requirements of 
sections 202 and 205 of the UMRA.
    EPA has determined that this final rule contains no regulatory 
requirements that might significantly or uniquely affect small 
governments. The adoption and use of these methods is voluntary because 
drinking water systems can continue to use the existing approved 
methods. Thus, today's rule is not subject to the requirements of 
section 203 of the UMRA.

E. Executive Order 13132: Federalism

    Executive Order 13132, entitled ``Federalism'' (64 FR 43255, August 
10, 1999), requires EPA to develop an accountable process to ensure 
``meaningful and timely input by State and local officials in the 
development of regulatory policies that have federalism implications.'' 
``Policies that have federalism implications'' is defined in the 
Executive Order to include regulations that 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.''
    This final rule does not have Federalism implications. It will 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. There is no cost to State and 
local governments, and the final rule does not preempt State law. This 
final rule imposes no cost on any State, or local governments. This 
final rule merely provides for the voluntary use of three additional 
analytical methods for compliance determinations of uranium in drinking 
water. Thus, Executive Order 13132 does not apply to this final rule.

[[Page 52180]]

F. Executive Order 13175: Consultation and Coordination With Indian 
Tribal Governments

    Executive Order 13175, entitled ``Consultation and Coordination 
with Indian Tribal Governments'' (65 FR 67249, (November 9, 2000), 
requires EPA to develop an accountable process to ensure ``meaningful 
and timely input by tribal officials in the development of regulatory 
policies that have tribal implications.'' ``Policies that have tribal 
implications'' is defined in the Executive Order to include regulations 
that have ``substantial direct effects on one or more Indian tribes, on 
the relationship between the Federal Government and the Indian tribes, 
or on the distribution of power and responsibilities between the 
Federal government and Indian tribes.''
    This final rule does not have tribal implications. It will not have 
substantial direct effects on tribal governments, 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 in Executive Order 13175. 
There is no cost to tribal governments, and the final rule does not 
preempt tribal law. This final rule imposes no additional cost on any 
tribal government. This final rule merely provides for the voluntary 
use of three additional analytical methods for compliance 
determinations of uranium in drinking water. Thus, Executive Order 
13175 does not apply to this rule.

G. Executive Order 13045: Protection of Children From Environmental 
Health and Safety Risks

    Executive Order 13045: ``Protection of Children from Environmental 
Health Risks and Safety Risks'' (62 FR 19885 April 23, 1997) applies to 
any rule that: (1) Is determined to be ``economically significant'' as 
defined under Executive Order 12866, and (2) concerns an environmental 
health or safety risk that EPA has reason to believe may have a 
disproportionate effect on children. If the regulatory action meets 
both criteria, the Agency must evaluate the environmental health or 
safety effects of the planned rule on children, and explain why the 
planned regulation is preferable to other potentially effective and 
reasonably feasible alternatives considered by the Agency.
    EPA interprets Executive Order 13045 as applying only to those 
regulatory actions that are based on health or safety risks, such that 
the analysis required under section 5-501 of the Order has the 
potential to influence the regulation. This rule is not subject to 
Executive Order 13045 because it does not establish an environmental 
standard intended to mitigate health or safety risks. This final rule 
merely provides for the voluntary use of three additional analytical 
methods for compliance determinations of uranium in drinking water.

H. Executive Order 13211: Actions That Significantly Affect Energy 
Supply, Distribution, or Use

    This rule is not subject to Executive Order 13211, ``Actions 
Concerning Regulations That Significantly Affect Energy Supply, 
Distribution, or Use'' (66 FR 28355 (May 22, 2001)) because it is not a 
significant regulatory action under Executive Order 12866.

I. National Technology Transfer and Advancement Act

    Section 12(d) of the National Technology Transfer and Advancement 
Act of 1995 (``NTTAA''), Pub. L. 104-113, 12(d) (15 U.S.C. 272 note) 
directs EPA to use voluntary consensus standards in its regulatory 
activities unless to do so would be inconsistent with applicable law or 
otherwise impractical. Voluntary consensus standards are technical 
standards (e.g., materials specifications, test methods, sampling 
procedures, and business practices) that are developed or adopted by 
voluntary consensus standards bodies. The NTTAA directs EPA to provide 
Congress, through OMB, explanations when the Agency decides not to use 
available and applicable voluntary consensus standards.
    This rulemaking involves technical standards. In addition to 
approving EPA 200.8, EPA has decided to approve two voluntary consensus 
methods (ASTM International D5673-03, and the Standard Methods (SM) 
Committee 3125) for compliance determinations of uranium in drinking 
water. Approval of these methods is in accordance with the goals of the 
NTTAA. EPA believes that ICP-MS analytical methods could be more cost-
effective, less labor-intensive or more sensitive than some of the 
technologies previously approved in the December 2000 Radionuclides 
Rule. (65 FR 76708) This rule does not withdraw approval of any 
previously approved monitoring methods for uranium. Copies of both 
voluntary consensus methods are available for viewing at the docket 
facility identified in ADDRESSES section.

J. Congressional Review Act

    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. A Major rule cannot 
take effect until 60 days after it is published in the Federal 
Register. This action is not a ``major rule'' as defined by 5 U.S.C. 
804(2). This rule will be effective August 25, 2004.
