Elemental Mercury Used in Flow Meters, Natural Gas Manometers,
and Pyrometers; Proposed Significant New Use Rule
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: EPA is proposing a significant new use rule (SNUR) under
section 5(a)(2) of the Toxic Substances Control Act (TSCA) for
elemental mercury (CAS No. 7439-97-6) for use in flow meters, natural
gas manometers, and pyrometers, except for use in these articles when
they are in service as of the effective date of the final rule. This
action would require persons who intend to manufacture (including
import) or process elemental mercury for an activity that is designated
as a significant new use by this proposed rule to notify EPA at least
90 days before commencing that activity. Persons subject to the
provisions of this proposed rule would not be exempt from significant
new use reporting if they import into the United States or process
elemental mercury as part of an article. The required notification
would provide EPA with the opportunity to evaluate the intended use
and, if necessary, to prohibit or limit that activity before it occurs.

SUPPLEMENTARY INFORMATION:
I. General Information
A. Does this Action Apply to Me?
You may be potentially affected by this action if you manufacture
(defined by statute to include import) or process elemental mercury
used in flow meters, natural gas manometers, or pyrometers. Potentially
affected entities may include, but are not limited to, manufacturers of
instruments and related products for measuring, displaying, and
controlling industrial process variables (North American Industrial
Classification System (NAICS) code 334513). This listing is not
intended to be exhaustive, but rather provides a guide for readers
regarding entities likely to be affected by this action. Other types of
entities not listed in this unit could also be affected. The NAICS
codes have been provided to assist you and others in determining
whether this action might apply to certain entities. To determine
whether you or your business may be affected by this action, you should
carefully examine the applicability provisions in 40 CFR 721.5 for
SNUR-related obligations. If you have any questions regarding the
applicability of this action to a particular entity, consult the
technical person listed under FOR FURTHER INFORMATION CONTACT.
This action may also affect certain entities through pre-existing
import certification and export notification rules under TSCA. Persons
who import any chemical substance governed by a final SNUR are subject
to the TSCA section 13 (15 U.S.C. 2612) import certification
requirements and the corresponding regulations at 19 CFR 12.118 through
12.127 and 19 CFR 127.28. Those persons must certify that the shipment
of the chemical substance complies with all applicable rules and orders
under TSCA, including any SNUR requirements. The EPA policy in support
of import certification appears at 40 CFR part 707, subpart B. In
addition, any persons who export or intend to export a chemical
substance that is the subject of this proposed rule on or after October
13, 2009 are subject to the export notification provisions of TSCA
section 12(b) (15 U.S.C. 2611(b)), (see 40 CFR 721.20), and must comply
with the export notification requirements in 40 CFR part 707, subpart
D.
B. What Should I Consider as I Prepare My Comments for EPA?
1. Submitting CBI. Do not submit this information to EPA through
regulations.gov or e-mail. Clearly mark the part or all of the
information that you claim to be CBI. For CBI information in a disk or
CD-ROM that you mail to EPA, mark the outside of the disk or CD-ROM
that you mail to EPA, mark the outside of the disk or CD-ROM as CBI and
then identify electronically within the disk or CD-ROM the specific
information that is claimed as CBI. In addition to one complete version
of the comment that includes information claimed as CBI, a copy of the
comment that does not contain the information claimed as CBI must be
submitted for inclusion in the public docket. Information so marked
will not be disclosed except in accordance with procedures set forth in
40 CFR part 2.
2. Tips for preparing your comments. When submitting comments,
remember to:
i. Identify the document by docket ID number and other identifying
information (subject heading, Federal Register date and page number).
ii. Follow directions. The Agency may ask you to respond to
specific questions or organize comments by referencing a Code of
Federal Regulations (CFR) part or section number.
iii. Explain why you agree or disagree; suggest alternatives and
substitute language for your requested changes.
iv. Describe any assumptions and provide any technical information
and/or data that you used.
v. If you estimate potential costs or burdens, explain how you
arrived at your estimate in sufficient detail to allow for it to be
reproduced.
vi. Provide specific examples to illustrate your concerns and
suggest alternatives.
vii. Explain your views as clearly as possible, avoiding the use of
profanity or personal threats.
viii. Make sure to submit your comments by the comment period
deadline identified.
II. Background
A. What Action is the Agency Taking?
This proposed SNUR would require persons to notify EPA at least 90
days before commencing the manufacture, import, or processing of
elemental
[[Page 46709]]
mercury for any of the following significant new uses: Flow meters,
natural gas manometers, or pyrometers. This proposed rule does not
affect the manufacturing and processing of elemental mercury for use in
these articles when they are in service as of the effective date of the
final rule. EPA believes this proposed SNUR is necessary because
manufacturing, processing, use, or disposal of mercury associated with
these uses may produce significant changes in human and environmental
exposures. The rationale and objectives for this proposed SNUR are
explained in Unit IV.
B. What is the Agency's Authority for Taking this Action?
Section 5(a)(2) of TSCA (15 U.S.C. 2604(a)(2)) authorizes EPA to
determine that a use of a chemical substance is a ``significant new
use.'' EPA must make this determination by rule after considering all
relevant factors, including those listed in TSCA section 5(a)(2). Once
EPA determines that a use of a chemical substance is a significant new
use, TSCA section 5(a)(1)(B) requires persons to submit a significant
new use notice (SNUN) to EPA at least 90 days before they manufacture
or process the chemical substance for that use (15 U.S.C.
2604(a)(1)(B)). As described in Unit II.C., the general SNUR provisions
are found at 40 CFR part 721, subpart A.
C. Applicability of General Provisions
General provisions for SNURs appear under 40 CFR part 721, subpart
A. These provisions describe persons subject to the rule, recordkeeping
requirements, exemptions to reporting requirements, and applicability
of the rule to uses occurring before the effective date of the final
rule. However, 40 CFR 721.45(f) does not apply to this SNUR. As a
result, persons subject to the provisions of this proposed rule would
not be exempt from significant new use reporting if they import or
process elemental mercury as part of an article (see 40 CFR 721.5).
Conversely, the exemption from notification requirements for exported
articles (see 40 CFR 707.60(b)) remains in force. Thus, persons who
export elemental mercury as part of an article are not required to
provide export notification.
Provisions relating to user fees appear at 40 CFR part 700.
According to 40 CFR 721.1(c), persons subject to SNURs must comply with
the same notice requirements and EPA regulatory procedures as
submitters of Premanufacture Notices (PMNs) under TSCA section
5(a)(1)(A). In particular, these requirements include the information
submission requirements of TSCA section 5(b) and 5(d)(1), the
exemptions authorized by TSCA section 5(h)(1), (h)(2), (h)(3), and
(h)(5), and the regulations at 40 CFR part 720. Once EPA receives a
SNUN, EPA may take regulatory action under TSCA section 5(e), 5(f), 6,
or 7 to control the activities on which it has received the SNUN. If
EPA does not take action, EPA is required under TSCA section 5(g) to
explain in the Federal Register its reasons for not taking action.
Persons who export or intend to export a chemical substance
identified in a proposed or final SNUR are subject to the export
notification provisions of TSCA section 12(b). The regulations that
interpret TSCA section 12(b) appear at 40 CFR part 707, subpart D.
Persons who import a chemical substance identified in a final SNUR are
subject to the TSCA section 13 import certification requirements,
codified at 19 CFR 12.118 through 12.127 and 19 CFR 127.28. Such
persons must certify that the shipment of the chemical substance
complies with all applicable rules and orders under TSCA, including any
SNUR requirements. The EPA policy in support of import certification
appears at 40 CFR part 707, subpart B.
III. Summary of the Proposed Rule
A. Overview of Mercury and Mercury Uses
1. Mercury. This proposed rule applies to elemental mercury (CAS
No. 7439-97-6), which is a naturally occurring element. Because of its
unique properties (e.g., exists as a liquid at room temperature and
forms amalgams with many metals), elemental mercury has been used in
many industrial processes and consumer products. In addition to its
useful characteristics, mercury also is known to cause adverse health
effects in humans and wildlife. These effects can vary depending on the
form of mercury to which a person or animal is exposed, as well as the
magnitude, length, and frequency of exposure.
The most prevalent human and wildlife exposure to mercury results
from ingesting fish contaminated with methylmercury. Methylmercury is
an organo-metallic compound that is formed via the conversion of
elemental or inorganic mercury compounds by certain microorganisms and
other natural processes. For example, elemental mercury may evaporate
and be emitted into the atmosphere. Atmospheric mercury can be
deposited directly into water bodies or watersheds, where it can be
washed into surface waters via overland run-off. Once deposited in
sediments, certain microorganisms and other natural processes can
convert elemental mercury into methylmercury. Methylmercury
bioaccumulates, which means that it is taken up and concentrated in the
tissues of aquatic, mammalian, avian, and other wildlife. Methylmercury
is a highly toxic substance; a number of adverse health effects
associated with exposure to it have been identified in humans and in
animal studies. Most extensive are the data on neurotoxicity,
particularly in developing organisms. Fetuses, infants, and young
children generally are more sensitive to methylmercury's neurological
effects than adults.
In 2004, EPA and the Food and Drug Administration (FDA) issued a
national consumption advisory concerning mercury in fish. The advisory
contains recommended limits on the amount of certain types of fish and
shellfish that pregnant women and young children can safely consume. By
2005, all 50 states had issued fish consumption advisories for fish
from certain water bodies known to be contaminated by methylmercury,
see http://www.epa.gov/mercury/advisories.htm.
In addition to methylmercury, exposure to elemental mercury can
also pose health risks. Elemental mercury primarily causes health
effects when it is breathed as a vapor that can be absorbed through the
lungs. These exposures can occur when elemental mercury is spilled or
products that contain elemental mercury break, resulting in release of
mercury to the air, particularly in warm or poorly-ventilated indoor
spaces.
For a more detailed summary of background information (e.g.,
chemistry, environmental fate, exposure pathways, and health and
environmental effects), as well as references pertaining to elemental
mercury that EPA considered before proposing this rule, please refer to
EPA's proposed SNUR for mercury switches in motor vehicles, issued in
the Federal Register of July 11, 2006 (71 FR 39035)(FRL-7733-9), or in
the docket for the 2006 proposal under docket ID number EPA-HQ-OPPT-
2005-0036. All documents in the docket are listed in the docket's index
which is available at http://www.regulations.gov.
2. Mercury uses. Elemental mercury has been used in thousands of
products and applications. Over the past two decades, there has been a
dramatic drop in elemental mercury use by industries in the United
States. In response to increased concerns about exposure to
anthropogenic sources of mercury in the environment and also because of
the availability of suitable mercury-free
[[Page 46710]]
products, Federal and State governments have made efforts to limit the
use of elemental mercury in certain products. Various states have
banned or restricted the manufacture or sale of products containing
mercury, see http://www.epa.gov/epawaste/hazard/tsd/mercury/laws.htm.
On October 7, 2007, EPA issued a final SNUR for elemental mercury used
in convenience light switches, anti-lock braking system switches, and
active ride control system switches in certain motor vehicles (72 FR
56903).
In the past, elemental mercury was used in the manufacture of flow
meters, natural gas manometers, and pyrometers. The latest information
available to EPA indicates that the manufacture of these mercury-
containing articles has ceased (Ref. 1). EPA requests comments on
whether elemental mercury continues to be used in manufacturing
(including importing into the United States) flow meters, natural gas
manometers, or pyrometers. EPA also requests comment on whether
elementary mercury is being used in the remanufacturing of any of these
articles that remain in use.
3. Flow meters containing elemental mercury. Flow meters are
instruments which measure the flow rate of liquids or gases.
Historically, they have been used in civil service applications, e.g.,
water treatment plants, sewage plants, and power stations. Flow meters
contained up to 5 kilograms (kg) of elemental mercury. At present, the
sale of mercury-containing flow meters is banned in six states:
California, Maine, Massachusetts, New Hampshire, New York, and Vermont
(Ref. 4). Many mercury-free alternatives exist, including differential
pressure meters, positive displacement meters, velocity meters, and
mass meters. EPA found sufficient information to conclude that mercury-
containing flow meters are no longer manufactured in or imported into
the United States (Ref. 1).
4. Natural gas manometers containing elemental mercury. A manometer
is an instrument used to measure the pressure of gases or liquids. For
purposes of this proposed rule, a natural gas manometer means a
mercury-containing instrument used in the natural gas industry to
measure the pressure differential of natural gas in a pipeline. Mercury
manometers have been used in the natural gas industry on individual
wells, pipeline junctions, pipeline manifolds, compressor stations, and
distribution points. The manometers contain between 3.2 and 54.5 kg of
mercury. A common design for manometers is a U-shaped tube with one end
opened to the atmosphere and the other connected to a process.
Contained in the tube is a liquid (mercury, in the past). Pressure
differential is measured by comparing the liquid levels in each of the
two vertical sections of the tube. Seven states have enacted broad bans
on the sale of mercury manometers (Ref. 4), and Louisiana prohibits the
sale of mercury-containing natural gas manometers (Ref. 2). Available
information indicates that bellows orifice meters have replaced mercury
meters in the natural gas industry. EPA found sufficient information to
conclude that mercury-containing manometers are no longer manufactured
in or imported into the United States (Ref. 1).
5. Pyrometers containing elemental mercury. A pyrometer is an
instrument that is similar to a thermometer but is typically used to
measure extremely high temperatures in industrial processes such as in
foundries, for pottery and ceramic kiln work, and in automotive
applications. Historically, pyrometers contained mercury in sensing
units in amounts ranging between 5 and 10 grams of mercury. In recent
years, California, Maine, Massachusetts, New Hampshire, New York, and
Vermont have banned the sale of mercury-containing pyrometers (Ref. 4).
EPA found sufficient information to conclude that mercury-containing
pyrometers are no longer manufactured, or imported into the U.S. (Ref.
1).
6. Potential exposure and release. The typical lifecycle of flow
meters, natural gas manometers, and pyrometers includes several stages:
Manufacture, distribution in commerce, use, and waste management
(landfilling or recycling). At any point in the lifecycle, there is
potential for mercury to be released as liquid or vapor. Workers and
others can be exposed to the mercury and it can be released into water,
air, or onto land as the mercury is transported, stored, and handled
during manufacturing. While the flow meters, manometers, and pyrometers
are in use, the mercury can vaporize or spill due to breakage during
transport, installation, maintenance, refilling, or repair. Beginning
in the 1920s, mercury-containing manometers were used in the Louisiana
natural gas industry. Mercury from these manometers has been identified
as a source of soil contamination. (Ref. 3). Other opportunities for
release can occur at the end of the lifecycle of flow meters,
manometers, and pyrometers, as the devices are removed from equipment
and facilities, and handled during waste management.
B. Proposed Action
EPA is proposing to designate as significant new uses use of
elemental mercury in flow meters, natural gas manometers, or
pyrometers. However, use of elemental mercury in these articles when
they are in service as of the effective date of the final rule would
not be covered as a significant new use under this proposed SNUR.
Proposed definitions of ``flow meter,'' ``natural gas manometer,'' and
``pyrometer'' can be found at 40 CFR 721.10068 of the regulatory text
for this proposal.
This action would amend 40 CFR 721.10068 and require persons who
intend to manufacture or process elemental mercury for a use designated
by this proposed rule as a significant new use to notify EPA at least
90 days before commencing the manufacturing or processing of elemental
mercury for such significant new use. The required notification would
provide EPA with the opportunity to evaluate the intended use and, if
necessary, to prohibit or limit that activity before it occurs.
For this SNUR, EPA is proposing not to include the general
``article'' exemption at 40 CFR 721.45(f). Thus, persons importing or
processing elemental mercury (including when part of an article) for a
significant new use would be subject to the notification requirements
of 40 CFR 721.25. EPA proposes not to include this exemption because
flow meters, natural gas manometers, and pyrometers are articles, and a
primary concern associated with this SNUR is potential exposures
associated with the lifecycle of these uses. Further, it is possible to
reclaim elemental mercury from certain articles, which could be used to
produce flow meters, natural gas manometers, and pyrometers. EPA notes
that, in accordance with TSCA section 12(a) and 40 CFR 721.45(g),
persons who manufacture or process elemental mercury solely for export
would be exempt from the notification requirements of 40 CFR 721.25, if
when distributing the substance in commerce, it is labeled in
accordance with TSCA section 12(a)(1)(B). Further, EPA notes that the
exemption from the TSCA section 12(b) notification requirements for
exported articles (see 40 CFR 707.60(b)) would remain in force. Thus,
persons who export elemental mercury as part of an article would not be
required to provide export notification.
EPA believes elemental mercury is no longer used to manufacture
flow meters, natural gas manometers, or pyrometers, but some of these
articles may remain in service in the United States. EPA believes the
ongoing use of such
[[Page 46711]]
articles, including some maintenance and servicing activities, falls
outside the regulation of significant new uses, and EPA has clarified
this in the proposed rule text. Thus, the manufacturing and processing
of elemental mercury for use in these articles, provided they are in
service as of the effective date of the final rule, would not be
covered by the rule. For example, if an article that is in service as
of the effective date of the final rule is removed from service for
maintenance or servicing, including the addition of new mercury, and
then placed back into service, any manufacturing or processing of
mercury associated with that maintenance or servicing would not be
covered by the rule. Otherwise, the addition of new mercury to these
existing articles after the effective date of the final rule could
potentially trigger a significant new use notice under this proposed
rule (e.g., if it involved processing of the mercury), which is not
EPA's intent.
IV. Rationale and Objectives
A. Rationale
As summarized in Unit III.A., EPA has concerns regarding the
environmental fate and the exposure pathways that lead to the presence
of methylmercury in fish and the consumption of mercury-contaminated
fish by humans and wildlife. EPA is encouraged by the discontinuation
of the use of elemental mercury in the manufacturing of flow meters,
natural gas manometers, and pyrometers. However, EPA is concerned that
the manufacturing or processing of elemental mercury for use in flow
meters, natural gas manometers, or pyrometers could be reinitiated in
the future. Accordingly, EPA wants the opportunity to evaluate and
control, where appropriate, activities associated with those uses, if
such manufacturing or remanufacturing were to occur again. The required
notification provided by a SNUN would provide EPA with the opportunity
to evaluate activities associated with a significant new use and an
opportunity to protect against unreasonable risks, if any, from
exposure to mercury.
B. Objectives
Based on the considerations in Unit IV.A., EPA has the following
objectives with regard to the significant new uses that are designated
in this proposed rule:
1. EPA would receive notice of any person's intent to manufacture
or process elemental mercury for any of the described significant new
uses before that activity begins.
2. EPA would have an opportunity to review and evaluate data
submitted in a SNUN before the notice submitter begins manufacturing or
processing of elemental mercury for any of the described significant
new uses.
3. EPA would be able to regulate prospective manufacturers or
processors of elemental mercury before the described significant new
uses of the chemical substance occur, provided that regulation is
warranted pursuant to TSCA sections 5(e), 5(f), 6 or 7.
V. Significant New Use Determination
Section 5(a)(2) of TSCA states that EPA's determination that a use
of a chemical substance is a significant new use must be made after
consideration of all relevant factors including:
The projected volume of manufacturing and processing of a
chemical substance.
The extent to which a use changes the type or form of
exposure of human beings or the environment to a chemical substance.
The extent to which a use increases the magnitude and
duration of exposure of human beings or the environment to a chemical
substance.
The reasonably anticipated manner and methods of
manufacturing, processing, distribution in commerce, and disposal of a
chemical substance.
In addition to these factors enumerated in TSCA section 5(a)(2),
the statute authorizes EPA to consider any other relevant factors.
To determine what would constitute a significant new use of
elemental mercury, EPA considered the four factors listed in section
5(a)(2) of TSCA. The latest information available to EPA indicates that
there is no ongoing use of elemental mercury in the manufacture or
remanufacture of flow meters, natural gas manometers, or pyrometers.
Resumption of these uses of elemental mercury could result in a
significant increase in the magnitude and duration of exposure to
workers and the surrounding environment at facilities of all types in
the lifecycle, as well as an increase in releases which could
contribute additional mercury to the atmosphere for long-range
transport. Resumption of these uses could also result in exposures to
workers who had not previously worked in these facilities when
elemental mercury was commonly used, as well as exposures to workers
who are not currently being exposed to mercury in the manufacture of
flow meters, natural gas manometers, or pyrometers. Increases in
mercury releases could lead to increases in mercury concentrations in
the environment and reduction in overall ecosystem and human health
from consumption of mercury-contaminated fish.
EPA believes that any of these renewed uses of elemental mercury
would increase the magnitude and duration of exposure to humans and the
environment over that which would otherwise exist. Based upon the
relevant factors as discussed in this Unit, EPA has determined that any
manufacturing or processing of elemental mercury for use in flow
meters, natural gas manometers, or pyrometers is a significant new use.
VI. Alternatives
Before proposing this SNUR, EPA considered the following
alternative regulatory actions:
A. Promulgate a TSCA Section 8(a) Reporting Rule
Under a TSCA section 8(a) rule, EPA could, among other things,
generally require persons to report information to the Agency when they
intend to manufacture or process a listed chemical for a specific use
or any use. However, for elemental mercury used in flow meters, natural
gas manometers, and pyrometers, the use of TSCA section 8(a) rather
than SNUR authority would have several limitations. First, if EPA were
to require reporting under TSCA section 8(a) instead of TSCA section
5(a), EPA would not have the opportunity to review human and
environmental hazards and exposures associated with the proposed
significant new use and, if necessary, take immediate follow-up
regulatory action under TSCA sections 5(e) or 5(f) to prohibit or limit
the activity before it begins. In addition, EPA may not receive
important information from small businesses, because such firms
generally are exempt from TSCA section 8(a) reporting requirements. In
view of the level of health and environmental concerns about elemental
mercury, if used for the proposed significant new use, EPA believes
that a TSCA section 8(a) rule for this substance would not meet EPA's
regulatory objectives.
B. Regulate Elemental Mercury for Use in Flow Meters, Natural Gas
Manometers, and Pyrometers Under TSCA Section 6
EPA may regulate under TSCA section 6 if ``the Administrator finds
that there is a reasonable basis to conclude that the manufacture,
processing, distribution in commerce, use or disposal of a chemical
substance or mixture . . . presents or will present an unreasonable
risk of injury to health or the environment.'' (TSCA section
[[Page 46712]]
6(a)) Given that elemental mercury is no longer being used in the
manufacture of flow meters, natural gas manometers, or pyrometers, EPA
concluded that risk management action under TSCA section 6 is not
necessary at this time. This proposed SNUR would allow the Agency to
address the potential risks associated with the proposed significant
new use.
C. Allow the Exemption for Persons Who Import or Process Elemental
Mercury as Part of Articles That Could be Subject to the SNUR
Under the SNUR exemption provision at 40 CFR 721.45(f), a person
who imports or processes a substance covered by a SNUR identified in
subpart E of part 721 as part of an article is not generally subject to
the notification requirements of Sec. 721.25 for that substance.
However, EPA is concerned that exempting articles would render the SNUR
less effective because of the possibility that flow meters, natural gas
manometers, or pyrometers containing elemental mercury could be
imported or processed for uses subject to this proposed SNUR without
the submission of a SNUN. Because mercury-containing flow meters,
natural gas manometers and pyrometers are the primary concerns in this
SNUR, EPA wishes to include not only bulk elemental mercury but also
these and other articles when they contain elemental mercury imported
or processed for a significant new use. Thus, EPA is proposing to
promulgate this rule without the exemption generally provided for in
Sec. 721.45(f).
VII. Applicability of Rule to Uses Occurring Before Effective Date of
the Final Rule
As discussed in the Federal Register of April 24, 1990 (55 FR
17376), EPA has decided that the intent of section 5(a)(1)(B) of TSCA
is best served by designating a use as a significant new use as of the
date of publication of the proposed rule rather than as of the
effective date of the final rule. If uses begun after publication of
the proposed rule were considered ongoing rather than new, it would be
difficult for EPA to establish SNUR notice requirements, because a
person could defeat the SNUR by initiating the proposed significant new
use before the rule became final, and then argue that the use was
ongoing as of the effective date of the final rule. Thus, persons who
begin commercial manufacture or processing of the chemical substance
that would be regulated through this proposed rule, if finalized, would
have to cease any such activity before the effective date of the rule
if and when finalized. To resume their activities, these persons would
have to comply with all applicable SNUR notice requirements and wait
until the notice review period, including all extensions, expires. EPA
has promulgated provisions to allow persons to comply with this SNUR
before the effective date. If a person were to meet the conditions of
advance compliance under Sec. 721.45(h), that person would be
considered to have met the requirements of the final SNUR for those
activities.
VIII. Test Data and Other Information
EPA recognizes that TSCA section 5 does not require developing any
particular test data before submission of a SNUN. Persons are required
only to submit test data in their possession or control and to describe
any other data known to or reasonably ascertainable by them (15 U.S.C.
2604(d); 40 CFR 721.25). However, as a general matter, EPA recommends
that SNUN submitters include data that would permit a reasoned
evaluation of risks posed by the chemical substance during its
manufacture, processing, use, distribution in commerce, or disposal.
EPA encourages persons to consult with the Agency before submitting a
SNUN. As part of this optional pre-notice consultation, EPA would
discuss specific data it believes may be useful in evaluating a
significant new use. SNUNs submitted for significant new uses without
any test data may increase the likelihood that EPA will take action
under TSCA section 5(e) to prohibit or limit activities associated with
this chemical.
SNUN submitters should be aware that EPA will be better able to
evaluate SNUNs that provide detailed information on:
1. Human exposure and environmental releases that may result from
the significant new uses of the chemical substance.
2. Potential benefits of the chemical substance.
3. Information on risks posed by the chemical substances compared
to risks posed by potential substitutes.
IX. SNUN Submissions
SNUNs must be mailed to the Environmental Protection Agency, OPPT
Document Control Office (7407M), 1200 Pennsylvania Avenue, NW.,
Washington, D.C. 20460-0001. Information must be submitted in the form
and manner set forth in EPA Form No. 7710-25. This form is available
from the Environmental Assistance Division (7408M), 1200 Pennsylvania
Avenue, NW., Washington, D.C. 20460-0001 (see 40 CFR 721.25 and
720.40). Forms and information are also available electronically at
http://www.epa.gov/opptintr/newchems/pubs/pmnforms.htm.
X. Economic Analysis
EPA has evaluated the potential costs of establishing SNUR
reporting requirements for potential manufacturers and processors of
the chemical substance included in this proposed rule (Ref. 1). EPA's
economic analysis (Ref. 1), which is briefly summarized here, is
available in the docket for this proposed rule.
The costs of submission of a SNUN will not be incurred by any
company until a company decides to pursue a significant new use as
defined in this proposed SNUR. In the event that a SNUN is submitted,
costs are estimated at approximately $8,000 per SNUN submission, and
includes the cost for preparing and submitting the SNUN, and the
payment of a user fee. Businesses that submit a SNUN are either subject
to a $2,500 user fee required by 40 CFR 700.45(b)(2)(iii), or, if they
are a small business with annual sales of less than $40 million when
combined with those of the parent company (if any), a reduced user fee
of $100 (40 CFR 700.45(b)(1)). In its evaluation of this rule, EPA also
considered the potential costs a company might incur by avoiding or
delaying the significant new use in the future, but these costs have
not been quantified.
In addition to comments on all aspects of this proposal, the Agency
is specifically interested in comments and supporting information on
the following questions related to assumptions used in the Agency's
analysis:
Do you know of any current domestic production of mercury flow
meters for the uses defined as significant in this rule that EPA
missed? If yes, please provide detailed information.
Are mercury flow meters currently available in the market place for
the uses defined as significant in this rule? If yes, please provide
detailed information.
Does the analysis capture the lost option value of mercury flow
meters? If no, please provide specific information that you believe
should be included.
Are the costs for preparing and submitting a SNUN comparable to the
costs for preparing and submitting a PMN? If not, in what ways is it
different?
Providing supporting and detailed information for comments on these
points will be used by EPA to review
[[Page 46713]]
related assumptions in the economic analysis as it prepares the final
rule.

XII. Statutory and Executive Order Reviews
A. Executive Order 12866: Regulatory Planning and Review
Under Executive Order 12866, entitled Regulatory Planning and
Review (58 FR 51735, October 4, 1993), the Office of Management and
Budget (OMB) has determined that this proposed SNUR is a ``significant
regulatory action,'' because it meets the criteria in section 3(f) of
the Executive Order. Accordingly, this action was submitted to the OMB
for review under Executive Order 12866 and any changes made based on
OMB recommendations have been documented in the public docket for this
rulemaking as required by section 6(a)(3)(E) of the Executive Order.
B. Paperwork Reduction Act
According to the Paperwork Reduction Act (PRA), 44 U.S.C. 3501 et
seq., an Agency may not conduct or sponsor, and a person is not
required to respond to a collection of information that requires OMB
approval under the PRA, unless it has been approved by OMB and displays
a currently valid OMB control number. The OMB control numbers for EPA's
regulations in Title 40 of the CFR, after appearing in the Federal
Register, are listed in 40 CFR, part 9, and included on the related
collection instrument, or form, if applicable.
The information collection requirements related to this action have
already been approved by OMB pursuant to the PRA under OMB control
number 2070-0038 (EPA ICR No. 1188). This action does not impose any
burden requiring additional OMB approval. If an entity were to submit a
SNUN to the Agency, the annual burden is estimated to average 110 hours
per response. This burden estimate includes the time needed to review
instructions, search existing data sources, gather and maintain the
data needed, and complete, review, and submit the required SNUN.
Send any comments about the accuracy of the burden estimate, and
any suggested methods for minimizing respondent burden, including
through the use of automated collection techniques, to the Director,
Collection Strategies Division, Office of Environmental Information
(2822T), Environmental Protection Agency, 1200 Pennsylvania Ave., NW.,
Washington, D.C. 20460-0001. Please remember to include the OMB control
number in any correspondence, but do not submit any completed forms to
this address.
C. Regulatory Flexibility Act
Pursuant to section 605(b) of the Regulatory Flexibility Act (RFA)
(5 U.S.C. 601 et seq.), the Agency hereby certifies that promulgation
of this SNUR would not have a significant adverse economic impact on a
substantial number of small entities. The rationale supporting this
conclusion is as follows. A SNUR applies to any person (including small
or large entities) who intends to engage in any activity described in
the rule as a ``significant new use.'' By definition of the word
``new,'' and based on all information currently available to EPA, it
appears that no small or large entities presently engage in such
activity. Since this proposed SNUR would require a person who intends
to engage in such activity in the future to first notify EPA by
submitting a SNUN, no economic impact will occur unless someone files a
SNUN to pursue a significant new use in the future or forgoes profits
by avoiding or delaying the significant new use. Although some small
entities may decide to conduct such activities in the future, EPA
cannot presently determine how many, if any, there may be. However,
EPA's experience to date is that, in response to the promulgation of
over 1,000 SNURs, the Agency receives on average only 5 notices per
year. Of those SNUNs submitted, only one appears to be from a small
entity in response to any SNUR. Therefore, EPA believes that the
potential economic impact of complying with this SNUR is not expected
to be significant or adversely impact a substantial number of small
entities. In a SNUR that published as a final rule on August 8, 1997
(62 FR 42690)(FRL-5735-4), the Agency presented its general
determination that proposed and final SNURs are not expected to have a
significant economic impact on a substantial number of small entities,
which was provided to the Chief Counsel for Advocacy of the Small
Business Administration.
D. Unfunded Mandates Reform Act
Based on EPA's experience with proposing and finalizing SNURs,
State, local, and Tribal governments have not been impacted by these
rulemakings, and EPA does not have any reason to believe that any
State, local, or Tribal government would be impacted by this
rulemaking. As such, EPA has determined that this regulatory action
would not impose any enforceable duty, contain any unfunded mandate, or
otherwise have any effect on small governments subject to the
requirements of sections 202, 203, 204, or 205 of the Unfunded Mandates
Reform Act of 1995 (UMRA) (Public Law 104-4).
E. Executive Order 13132: Federalism
This action would not have a substantial direct effect on 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, entitled
Federalism (64 FR 43255, August 10, 1999).
F. Executive Order 13175: Consultation and Coordination with Indian
Tribal Governments
This proposed rule would not have Tribal implications because it is
not expected to have substantial direct effects on Indian Tribes. This
proposed rule would not significantly or uniquely affect the
communities of Indian Tribal governments, nor would it involve or
impose any requirements that affect Indian Tribes. Accordingly, the
[[Page 46714]]
requirements of Executive Order 13175, entitled Consultation and
Coordination with Indian Tribal Governments (65 FR 67249, November 6,
2000), do not apply to this proposed rule.
G. Executive Order 13045: Protection of Children from Environmental
Health Risks and Safety Risks
This action is not subject to Executive Order 13045, entitled
Protection of Children from Environmental Health Risks and Safety Risks
(62 FR 19885, April 23, 1997), because this is not an economically
significant regulatory action as defined by Executive Order 12866, and
this action does not address environmental health or safety risks
disproportionately affecting children.
H. Executive Order 13211: Actions that Significantly Affect Energy
Supply, Distribution, or Use
This proposed rule is not subject to Executive Order 13211,
entitled Actions Concerning Regulations That Significantly Affect
Energy Supply, Distribution, or Use (66 FR 28355, May 22, 2001),
because this action is not expected to affect energy supply,
distribution, or use.
I. National Technology Transfer Advancement Act
Since this action does not involve any technical standards; section
12(d) of the National Technology Transfer and Advancement Act of 1995
(NTTAA), Public Law 104-113, section 12(d) (15 U.S.C. 272 note), does
not apply to this action.
J. Executive Order 12898: Federal Actions to Address Environmental
Justice in Minority Populations and Low-Income Populations
This action does not entail special considerations of environmental
justice related issues as delineated by Executive Order 12898, entitled
Federal Actions to Address Environmental Justice in Minority
Populations and Low-Income Populations (59 FR 7629, February 16, 1994).
