I. Background
On May 20, 2003 (68 FR 27646), we issued the NESHAP for integrated
iron and steel manufacturing facilities (40 CFR part 63, subpart
FFFFF). The NESHAP implement section 112(d) of the Clean Air Act (CAA)
by requiring all major sources to meet emission standards for hazardous
air pollutants (HAP) reflecting application of the maximum achievable
control technology (MACT). The NESHAP establish emission limitations
for emission sources in each new or existing sinter plant, blast
furnace, and basic oxygen process furnace (BOPF) shop.
After promulgation of the NESHAP, five steel companies and one
trade association filed a petition for review challenging the final
standards (AK Steel Corporation et al. v. U.S. Environmental Protection
Agency, no. 03-1207, DC Cir.). The petitioners raised issues
concerning:
Failure to respond to substantive industry comments
questioning the definitions, subcategorization, control technologies
identified, emission standards, testing and monitoring, and other
aspects of the rule;
Failure to provide justification for setting standards for
ladle metallurgy operations, sinter plant discharge ends, and sinter
coolers;
Requiring bag leak detection systems to be used for
positive pressure baghouse systems that discharge without stacks or
from baghouse systems with continuous emission monitors;
Applying emission standards to control devices that do not
discharge to the ambient air;
Imposing stringent testing, monitoring, inspection, and
reporting requirements on insignificant sources;
Providing for the establishment of source-specific opacity
limitations based on opacity observations made during required source
performance testing and by specifying use of infeasible technical
requirements for such observations; and
Failing adequately to consider health threshold levels and
to allow for alternative emission standards, performance testing
requirements or monitoring methods that are demonstrated to provide
comparable protection to public health and the environment.
EPA and petitioners anticipate that the amendments to the NESHAP
proposed in this notice will resolve these concerns, and EPA and
industry petitioners have entered into a settlement agreement whereby
EPA agreed to sign a notice proposing these amendments by September 23,
2005. See 70 FR 36383, June 23, 2005 (public notice of settlement
agreement pursuant to section 113 of the CAA; EPA received no adverse
comment on this notice of settlement).
II. Summary of the Proposed Amendments
The proposed amendments would revise the applicability of the
emission limits for sinter cooler stacks at new and existing sinter
plants. The revised limits would apply to each sinter cooler instead of
to each sinter cooler stack. We are also proposing a 10 percent opacity
limit for a sinter cooler at an existing sinter plant instead of the
current particulate matter (PM) emission limit of 0.03 grains per dry
standard cubic feet (gr/dscf). The proposed amendments would also
clarify (in a new footnote to Table 1 of 40 CFR part 63, subpart FFFFF)
that PM limits do not apply to discharges inside a building or
structure housing a discharge end at an existing sinter plant, inside a
casthouse at an existing blast furnace, or inside an existing BOPF shop
that is subject to a roof monitor opacity limit. We are proposing to
change the frequency for conducting subsequent performance tests from
twice each permit term to once each permit term for emission units
equipped with a baghouse. Repeat performance tests would still be
required at least twice each permit term for a sinter cooler at an
existing sinter plant, for each unit equipped with a control device
other than a baghouse, and for each affected source without a title V
operating permit.
The proposed amendments would revise the operating limit in 40 CFR
63.7790(b)(3) for an electrostatic precipitator (ESP) that controls
emissions from a BOPF to require that the hourly average opacity of
emissions from the control device be maintained at or below 10 percent.
Section 63.7830(b) of the NESHAP requires a bag leak detection
system for each baghouse used to meet a PM limit. The proposed
amendments would add an alternative allowing plants to use a continuous
opacity monitoring system (COMS) to monitor the opacity of emissions
exiting each control device stack. A bag leak detection system or
[[Page 51308]]
COMS would not be required for a positive-pressure baghouse not
equipped with exhaust gas stacks that was installed before August 30,
2005.
We are proposing to revise the requirements for operation and
maintenance (O&M) plans. The proposed amendments would expand the
corrective action procedures in 40 CFR 63.7800(b)(4) to apply to
baghouses equipped with COMS in addition to those with bag leak
detection systems. Plants would be required to initiate corrective
action if a bag leak detection system alarm is triggered or if
emissions from a baghouse equipped with a COMS exceed an hourly average
opacity of 5 percent.
We are also proposing to add corrective action procedures for other
types of control devices. If a venturi scrubber equipped with
continuous parameter monitoring systems (CPMS) or an ESP equipped with
a COMS exceeds the opacity operating limit, plants would be required to
take corrective action consistent with their site-specific monitoring
plan. New provisions in 40 CFR 63.7833 would require plants to initiate
corrective action to determine the cause of the exceedance within 1
hour and to measure operating parameter value(s) for the emission unit
within 24 hours of the exceedance. If the measured value(s) meet the
applicable operating limit, the corrective action is successful and the
emission unit would be in compliance with the applicable operating
limit. If the initial corrective action is not successful, additional
corrective action would be required within the next 24 hours. Plants
would re-measure the operating parameter(s) and if the corrective
action is successful, the emission unit would be in compliance with the
applicable operating limit. If the second attempt at corrective action
is not successful, the plant would report the exceedance as a deviation
in the next semiannual compliance report.
In other amendments, we are proposing to clarify the requirements
for establishing venturi scrubber parametric operating limits in 40 CFR
63.7824(b) by stating that plants may establish the limit during the
initial performance test or during any other performance test that
meets the emission limit. We are also proposing to revise the
definition of ``ladle metallurgy'' by stating that vacuum degassing is
not included in the definition. We are also proposing changes to Table
4 to 40 CFR part 63, subpart FFFFF, which would clarify the
applicability of certain monitoring, recordkeeping, and reporting
requirements in the NESHAP General Provisions (40 CFR part 63, subpart
A) to the rule and correct errors in certain entries.
III. Rationale for the Proposed Amendments
A. Why Are We Proposing To Revise the Emission Limitations?
Sinter Coolers
The petitioners objected to the PM emission limit for sinter cooler
stacks (0.03 gr/dscf) for a variety of reasons, including the lack of
HAP data to support a standard, the de minimus nature of the emissions,
and the high costs for testing and monitoring. In addition, several
plants have coolers without stacks that cannot be tested by EPA Method
5 (40 CFR part 60, appendix A). Petitioners contend that an opacity
limit would be technically feasible and consistent with State rules.
We agree with the commenters' concerns that the sinter cooler
standard should accommodate coolers without stacks. For a sinter cooler
at a new affected source, we are proposing to revise the current limit
to apply to emissions from each sinter cooler rather than each sinter
cooler stack. For sinter coolers at an existing affected source, we are
proposing to revise the MACT floor based on State rules and new opacity
data. As discussed below, the data clearly show that a 10 percent limit
(6-minute average) provides a reasonably accurate picture of the
performance achieved by the best-performing sources and can be achieved
on a continuing basis.
Our review of sinter coolers indicate that some coolers do not have
stacks, and their design and operation make it impractical to install a
stack. As promulgated, the final rule does not apply an emission limit
to coolers without stacks. We reviewed existing State regulations for
sinter coolers and found that some States have opacity limits which
provide a practical means for limiting emissions from coolers with and
without stacks. The MACT floor based on current opacity limits is
determined by the 10 percent (6-minute average) limit that applies to
three sinter plants with five sinter coolers in Lake County, Indiana.
See Indiana Administrative Code (IAC), 326 IAC 6-1-11.1(d)(7)(A)-(B).
We attempted to obtain opacity data for these sources, but the coolers
are seldom inspected by the State agency because they are such a low-
emitting emission source. We also attempted to obtain self-monitoring
data performed by the plants. Data were available for only one of the
sinter plant coolers. The plant provided data for 366 observations
covering 13 months. The 99th percentile of the observations was 8
percent opacity, and only two observations exceeded 10 percent. These
data indicate that a MACT floor of 10 percent opacity based on current
State regulations is a reasonable representation of the opacity that
can be achieved on a continuing basis by sinter coolers. The proposed
opacity limit would apply to the sinter cooler and any discharge of
emissions from the cooler; it would not apply to the material transfer
point where the sinter is removed from the cooler.
Discharges Inside Buildings
The petitioners explained that at some facilities, control devices
discharge to the interior of buildings and not to the ambient air.
Other facilities are able to meet opacity limits by using flame
suppression and do not have a control device. Facilities with capture
systems leading to a control device that then discharge within the
building are in effect no different than those systems used to suppress
emissions to meet the opacity limit for a building.
The petitioners are correct that the language of the emission
limits in Table 1 to 40 CFR part 63, subpart FFFFF (``emissions
discharged to the atmosphere''), could be construed to include
emissions discharged inside buildings. This is not our intent. In
response to the petitioners' concerns, we are proposing amendments to
Table 1 to 40 CFR part 63, subpart FFFFF, that would add a footnote to
each PM limit for a control device at an existing source stating that
the limit does not apply to discharges inside a blast furnace
casthouse, BOPF shop, or building housing the discharge end at a sinter
plant. The applicable emission limit for these emissions and other
fugitive emissions that are discharged through the roof monitor is the
opacity limit for the building cited in Table 1 to 40 CFR part 63,
subpart FFFFF.
Parametric Operating Limit for Electrostatic Precipitators
The NESHAP establish an operating limit for ESP that control
emissions from a BOPF. Plant operators are to set the site-specific
limit based on COMS measurements made during the performance test. The
commenters contend that variations in BOPF operations make it
impractical to set a parametric limit based on a short-term performance
test. In addition, the presence of water vapor or steam, which is
necessary for optimizing ESP performance, raises issues of
interferences in COM readings. The commenters support a 20 percent
opacity limit (6-minute average), consistent with State regulations,
permit
[[Page 51309]]
requirements, and the NESHAP for Industrial, Commercial, and
Institutional Boilers and Process Heaters (69 FR 55218, September 13,
2004). The petitioners also stated that exceedance of the parametric
limit should result in triggering corrective action rather than a
violation.
We agree with the petitioners' arguments and are proposing to
change the ESP operating limit to a fixed opacity level of 10 percent.
This proposed operating limit would be an hourly average to be
consistent with other parametric operating limits for control devices.
We are also proposing that plant operators take corrective action if
the operating limit for an ESP or venturi scrubber is exceeded. The
proposed amendments would require plant operators to initiate
corrective action within 1 hour. If the limit is still exceeded after
24 hours (i.e., the corrective action was unsuccessful), plant
operators would need to take additional corrective action. If the
operating limit is exceeded after 24 more hours, we are proposing that
the exceedance would be reported as a deviation in the semiannual
compliance report. These provisions would not apply in the event of a
malfunction, which would be handled according to the startup, shutdown,
and malfunction plan.
B. Why Are We Proposing To Amend Monitoring Requirements for Baghouses?
Baghouses Without Exhaust Stacks
The NESHAP require a bag leak detection system for each baghouse
used to meet the PM limits. The petitioners point out that EPA's
``Fabric Filter Bag Leak Detection Guidance'' (EPA-454/R-98-015,
September 1997) states that only fabric filters with exhaust stacks are
covered by this guidance. Some of the emissions sources covered by the
NESHAP use positive pressure baghouses which do not use an exhaust
stack. EPA has recognized this problem in other rules.
We agree with the commenters that bag leak detection systems should
not be required for fabric filters without exhaust stacks. In response
to the commenters' concerns, we are proposing to revise the rule to
clarify that bag leak detection systems are required only for negative
pressure baghouses and positive pressure baghouses with a stack.
COMS as an Alternative to Bag Leak Detection Systems
The petitioners also point out that some companies already have
COMS in place, may be required to install COMS due to State, local, or
permit requirements, or may opt for COMS instead of bag leak detection
systems if given the choice. These companies should not be required to
operate duplicative baghouse monitoring systems.
We agree that COMS, which provide a direct measure of opacity, are
certainly a suitable alternative to bag leak detection systems. In
response to the petitioners' concerns, we are proposing to increase the
flexibility of the NESHAP by adding COMS as a monitoring alternative.
This approach is consistent with several other MACT standards, as well
as the recent amendments to the new source performance standards (NSPS)
for electric arc furnaces (70 FR 8523, February 22, 2005). The proposed
amendments would require that the COMS for baghouses meet the same
requirements as COMS for ESP. The same corrective action requirements
for baghouses also would apply. If a bag leak detection system alarm is
triggered or emissions from a baghouse equipped with a COMS exceed an
hourly average opacity of 5 percent, the proposed amendments would
require plants to initiate corrective action within specified time
limits. We are proposing the 5 percent trigger because it is consistent
with other MACT standards as well as with the amendments to the NSPS
for electric arc furnaces cited above.
C. Why Are We Proposing To Revise the Requirements for Repeat
Performance Tests?
The petitioners asked EPA to amend the rule to reduce the costs
associated with demonstrating continuous compliance, particularly for
well-controlled emissions sources. We are proposing to reduce the
frequency of repeat PM and opacity performance tests from twice each
permit term to once per term for emission units equipped with a
baghouse. The reduced frequency would apply to minor emission units
equipped with baghouses because performance would be continuously
monitored by a bag leak detection system or COMS.
D. Why Are We Proposing To Revise the Definition of ``Ladle
Metallurgy'' To Exclude Vacuum Degassing?
Vacuum degassing is an advanced steel refining process to remove
oxygen, hydrogen, and nitrogen in a vacuum to produce ultra-low carbon
steel for certain applications. As such, this process could fall within
the definition of ``ladle metallurgy.'' The petitioners argue that EPA
did not acknowledge the fundamental control technology differences for
vacuum degassing operations compared to ladle metallurgy operations
which are typically controlled by baghouses. They explain that many
BOPF shops have vacuum degassing facilities and all use steam ejector/
condenser systems; baghouses are not suitable control systems because
of the inherent moisture in the gas downstream of the steam ejectors.
Although PM emissions are low, these facilities would not be able to
achieve the limit for new or existing ladle metallurgy operations.
We agree with the petitioners that the definition of ``ladle
metallurgy'' (a secondary steelmaking process that is performed in a
ladle after initial refining in a BOPF to adjust the chemical and/or
mechanical properties of steel) could be interpreted to include vacuum
degassing. In response to the petitioners' concerns, we are proposing
to revise the definition of ``ladle metallurgy'' to specifically
exclude vacuum degassing.
IV. Impacts of the Proposed Amendments
The proposed amendments would not affect the level of emissions
control required by the existing NESHAP or the nonair, health,
environmental, and energy impacts. However, the costs of implementing
the existing rule would be reduced in future years. For example, the
proposed reduction in subsequent performance tests for an emissions
source equipped with a baghouse would reduce the nationwide cost of PM
testing over the next 5 years from $270,000/year to $180,000/year, a
savings of $90,000/year.
V. Statutory and Executive Order Reviews
A. Executive Order 12866: Regulatory Planning and Review
Under Executive Order 12866 (58 FR 51735, October 4, 1993), EPA
must determine whether the regulatory action is ``significant'' and,
therefore, subject to review by the Office of Management and Budget
(OMB) and the requirements of the Executive Order. The Executive Order
defines a ``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;
[[Page 51310]]
(2) Create a serious inconsistency or otherwise interfere with an
action taken or planned by another agency;
(3) Materially alter the budgetary impact of entitlement, 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 these proposed amendments are not a
``significant regulatory action'' under the terms of Executive Order
12866 and are, therefore, not subject to OMB review.
B. Paperwork Reduction Act
This action does not impose any new information collection burden.
The proposed amendments provide additional flexibility through revised
requirements for monitoring operational parameters which would not
increase the existing information collection burden. Other proposed
amendments, such as the reduction in subsequent PM performance tests
for certain emissions sources, is expected to decrease the information
collection burden in future years. However, OMB has previously approved
the information collection requirements contained in the existing
regulations (40 CFR part 63, subpart FFFFF) under the provisions of the
Paperwork Reduction Act, 44 U.S.C. 3501 et seq. and has assigned OMB
control number 2060-0517, EPA Information Collection Request (ICR)
number 2003.02. A copy of the OMB approved ICR may be obtained from
Susan Auby, by mail at the Office of Environmental Information,
Collection Strategies Division, U.S. EPA (2822T), 1200 Pennsylvania
Avenue, NW., Washington, DC 20460, by e-mail at Auby.Susan@epa.gov, or
by calling (202) 566-1672.
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.
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 part 63 are listed in 40 CFR part 9.
C. Regulatory Flexibility Act
The Regulatory Flexibility Act 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
would not have a significant economic impact on a substantial number of
small entities. Small entities include small businesses, small not-for-
profit enterprises, and small governmental jurisdictions.
For the purposes of assessing the impacts of today's proposed
amendments on small entities, small entity is defined as: (1) A small
business as defined by the Small Business Administration's 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.
After considering the economic impacts of today's proposed
amendments on small entities, I certify that this action will not have
a significant economic impact on a substantial number of small
entities. The proposed amendments would not impose any requirements on
small entities. There are no small entities in the regulated industry.
We continue to be interested in the potential impacts of the proposed
rule on small entities and welcome comments on issues related to such
impacts.
D. Unfunded Mandates Reform Act
Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), Public
Law 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 by State, local, and tribal governments, in
the aggregate, or to the private sector, of $100 million or more in any
1 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.
EPA has determined that the proposed amendments do not contain a
Federal mandate that may result in expenditures of $100 million or more
for State, local, and tribal governments, in the aggregate, or to the
private sector in any 1 year. Thus, today's proposed amendments are not
subject to the requirements of sections 202 and 205 of the UMRA. In
addition, EPA has determined that the proposed amendments contain no
regulatory requirements that might significantly or uniquely affect
small governments, because they contain no requirements that apply to
such governments or impose obligations upon them.
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'' are 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.''
[[Page 51311]]
The proposed amendments do not have federalism implications. They
would 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. None of the affected
plants are owned or operated by State governments. Thus, Executive
Order 13132 does not apply to the proposed amendments. In the spirit of
Executive Order 13132, and consistent with EPA policy to promote
communications between EPA and State and local governments, EPA
specifically solicits comment on this proposed rule from State and
local officials.
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 6, 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.'' The proposed amendments do
not have tribal implications, as specified in Executive Order 13175.
They would 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. No tribal governments own plants subject to the MACT standards
for integrated iron and steel manufacturing. Thus, Executive Order
13175 does not apply to today's proposed amendments. EPA specifically
solicits additional comment on this proposed rule from tribal
officials.
G. Executive Order 13045: Protection of Children From Environmental
Health & Safety Risks
Executive Order 13045 (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, EPA 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 EPA.
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 Executive Order has
the potential to influence the regulation. The proposed amendments are
not subject to the Executive Order because they are based on control
technology and not on health or safety risks.
H. Executive Order 13211: Actions That Significantly Affect Energy
Supply, Distribution, or Use
The proposed amendments are not subject to Executive Order 13211
(66 FR 28355, May 22, 2001) because they are not a significant
regulatory action under Executive Order 12866.
I. National Technology Transfer Advancement Act
Under section 12(d) of the National Technology Transfer and
Advancement Act of 1995 (NTTAA), Public Law No. 104-113, Sec. 12(d)
(15 U.S.C. 272 note) directs EPA to use voluntary consensus standards
(VCS) in its regulatory activities, unless to do so would be
inconsistent with applicable law or otherwise impractical. The VCS are
technical standards (e.g., materials specifications, test methods,
sampling procedures, and business practices) that are developed or
adopted VCS bodies. The NTTAA directs EPA to provide Congress, through
OMB, explanations when the Agency does not use available and applicable
VCS.
The proposed amendments do not involve technical standards.
Therefore, EPA is not considering the use of any VCS.
