National Emission Standards for Hazardous Air Pollutants From
Secondary Lead Smelting
AGENCY: Environmental Protection Agency (EPA).
[[Page 32210]]
ACTION: Direct final rule: Amendments to rule.
-----------------------------------------------------------------------
SUMMARY: This action amends the national emission standards for
hazardous air pollutants (NESHAP) for new and existing secondary lead
smelters. Changes to the NESHAP are being made to address comments
received in petitions to reconsider sent to the EPA following
promulgation of the final rule. These changes affect several aspects of
the final rule including applicability of the THC limit for collocated
blast and reverberatory furnaces, minimum baghouse standard operating
procedure (SOP) requirements, and bag leak detection system
specifications and requirements. Several minor changes are also being
made to clarify the intent of the rule. The EPA is making these
amendments as a direct final rule without prior proposal because the
Agency views this as a noncontroversial amendment and anticipates no
significant adverse comments.
The EPA is also proposing these amendments in the Proposed Rules
Section of this Federal Register. If no significant adverse comments
are received in response to this direct final rule, no further action
is contemplated in relation to the proposal. If the EPA receives
significant adverse comments, the direct final rule will be withdrawn
and all public comments received will be addressed in a subsequent
final rule based on the proposed rule. The EPA will not institute a
second comment period on the proposal. Any parties interested in
commenting on the amendments should do so at this time.
DATES: Effective Date. This action will be effective August 4, 1997
unless significant adverse comments on this action are received by July
14, 1997. If significant adverse comments are received, the EPA will
withdraw this Direct Final rule and will publish timely notice of the
withdrawal inthe Federal Register, and all public comments received
will be addressed in a subsequent final rule.
Judicial Review. Under section 307(b)(1) of the Act, judicial
review of a NESHAP is available only by filing a petition for review in
the U.S. Court of Appeals for the District of Columbia Circuit within
60 days of today's publication of this final rule. Under section
307(b)(2) of the Act, the requirements that are the subject of today's
notice may not be challenged later in civil or criminal proceedings
brought by the EPA to enforce these requirements.
ADDRESSES: Docket. Docket No. A-92-43, containing information
considered by the EPA in development of the promulgated standards, is
available for public inspection and copying between 8:00 a.m. and 5:30
p.m., Monday through Friday except for Federal holidays, at the

I. Background
The NESHAP for secondary lead smelting (40 CFR part 63, subpart X)
was proposed in the Federal Register on June 9, 1994 (59 FR 29750). The
EPA received 31 letters commenting on the proposed rule and proposed
area source listing. After considering fully the comments received, the
EPA promulgated this NESHAP in the Federal Register on June 23, 1995
(60 FR 32587).
The final rule establishes emission limits for lead, as a surrogate
for all metallic Hazardous Air Pollutants (HAP), from smelting
furnaces, refining kettles, agglomerating furnaces, dryers, and
fugitive dust sources at secondary lead smelters. The final rule also
establishes emission limits for total hydrocarbons (THC), as a
surrogate for HAP organics, from smelting furnaces. Work practice
standards (i.e., minimum hood face velocities, and building enclosures)
were specified for the capture and control of process fugitive sources
including furnace charging equipment and tapping locations, refining
kettles, driers, and agglomerating furnace vents and taps. The final
rule also requires smelters to develop site specific Standard Operating
Procedures (SOP) manuals for fugitive dust control and baghouse
operation and maintenance. Minimum SOP requirements were specified in
the rule.
Following publication of the final rule, the EPA received three
petitions for reconsideration pursuant to section 307(d)(7)(B) of the
act from secondary lead smelter owners and operators, and the
Association of Battery Recyclers, an industry trade association that
represents the majority of the secondary lead smelters in the United
States.
The petitioners had subsantive objections to several technical
requirements in the final rule that were not included in the proposal.
The EPA has determined that several of the objections contained in the
petitions, though not dealing with critical parts of the rule, are
properly founded and that the rule should be revised. The EPA extended
the compliance and SOP submittal dates by six months, in order to allow
affected sources time to address the changes being made in this action.
The extension was published in the Federal Register on December 12,
1996 (60 FR 65334). The EPA is making further amendments in this
document.
II. Summary
A. Summary of Promulgated Standards
The promulgated rule, as amended, establishes standards to limit
HAP emissions from smelting furnaces, refining kettles, agglomerating
furnaces, dryers, and fugitive dust sources at both major source and
area source secondary lead smelters. The promulgated rule does not
apply to primary lead smelters, lead refiners, or lead remelters.
1. Process Emission Sources
Owners and operators of all smelting furnace types must limit lead
compound emissions, which is a surrogate for all metal HAP, to no more
than 2.0 milligrams per dry standard cubic meter (mg/dscm; 0.00087
grains per dry standard cubic foot (gr/dscf)). Owners
[[Page 32211]]
and operators must limit THC emissions, which is a surrogate for all
organic HAP's, to varying levels depending on the smelting furnace
type. No THC limits apply to reverberatory, rotary, and electric
furnaces not collocated with blast furnaces.
Owners and operators of collocated blast furnaces and reverberatory
furnaces must comply with a THC limit of 20 parts per million by volume
(ppmv) as propane at 4 percent carbon dioxide (CO2) when
both furnaces are operating. Less stringent limits apply when the
reverberatory furnace is not operating. When the reverberatory furnace
is not operating, new blast furnaces collocated with reverberatory
furnaces must comply with a THC limit of 70 ppmv, and existing blast
furnaces must comply with a THC limit of 360 ppmv. For the purpose of
this rule, a collocated blast furnace and reverberatory furnace is
defined as operation at the same site of a reverberatory furnace and a
blast furnace with the volumetric flow rate discharged from the
reverberatory furnaces being at least equal to that discharged from the
blast furnaces.
The THC standard for a collocated blast furnace and reverberatory
furnace is based on commingling the high-volume, high-temperature
(approximately 1000 deg.C) reverberatory exhaust with the low-volume,
low-temperature (approximately 100 deg.C) blast furnace exhaust to
incinerate the organic HAP in the blast furnace exhaust. Organics are
further reduced in a typical collocated blast furnace and reverberatory
configuration since the reverberatory furnace processes the majority of
the broken battery materials while the blast furnace processes
reverberatory slag and only small amounts of broken batteries.
Owners and operators of new blast furnaces not collocated with a
reverberatory furnace (as defined above) must comply with a THC limit
of 70 ppmv. Existing blast furnaces not collocated with a reverberatory
furnace must comply with a THC limit of 360 ppmv. The THC emissions
from each blast furnace charging chute at all smelters with blast
furnaces shall not exceed 0.20 kilograms per hour (kg/hr; 0.44 pounds
per hour (lb/hr)).
Table 2 in the attached regulatory text summarizes the emission
limits for smelting furnace process sources.
2. Process Fugitive Emission Sources
Owners and operators must comply with either of two process
fugitive emission control options. Each process fugitive emission
source must be controlled either by an enclosure-type hood that is
ventilated to a control device or must be fully enclosed within a total
enclosure that is ventilated to a control device. Lead compound
emissions, as a surrogate for all metal HAP's, from each hood or
building control device are limited to 2.0 mg/dscm (0.00087 gr/dscf).
Refining kettle enclosure hoods must have a minimum air velocity
into all hood openings (i.e., face velocity) of 75 meters per minute
(m/min; 250 feet per minute (fpm)), and the enclosure hoods over drying
kiln transition pieces must have a minimum face velocity of 110 m/min
(350 fpm). All other process fugitive emission sources (charging
points, lead and slag taps, and agglomerating furnaces) with an
enclosure hood must have a minimum face velocity of 90 m/min (300 fpm).
If a ventilated building is used to control process fugitive sources,
then it must be ventilated at such a rate as to maintain a lower than
ambient pressure within the building, ensuring that a in-draft will
exist at all doors and other openings.
Table 3 in the attached regulatory text summarizes the requirements
for process fugitive emission sources.
3. Fugitive Dust Sources
Fugitive dust emissions must be controlled by the measures
specified in a standard operating procedures (SOP) manual. The SOP must
be developed by the owner or operator of each smelter and submitted to
the Administrator for approval. The SOP must describe the measures that
will be used to control fugitive dust emissions from plant roadways;
the battery breaking area; the furnace, refining, and casting areas;
and the materials storage and handling areas. Acceptable control
measures include either a total enclosure of the fugitive dust source
and ventilation of the enclosure to a control device, or a combination
of partial enclosures, wet suppression, and pavement cleaning. Lead
compound emissions, as a surrogate for all metal HAP's, from enclosure
control devices must be limited to 2.0 mg/dscm (0.00087 gr/dscf).
4. Compliance Dates
Compliance for existing sources must be achieved no later than
December 23, 1997, or upon startup for new or reconstructed sources.
5. Compliance Test Methods
Compliance with the emission limits for lead compounds shall be
determined according to EPA Reference Method 12 (40 CFR part 60,
appendix A). EPA Reference Method 9 is not required for determining
compliance with the emission limits for lead compounds. Compliance with
the THC emission limits shall be determined according to EPA Reference
Method 25A (40 CFR part 60, appendix A). Concentrations of THC shall be
reported in ppmv, as propane, corrected to 4 percent CO2 to
correct for dilution. Sampling point locations shall be determined
according to EPA Reference Method 1, and stack gas conditions shall be
determined, as appropriate, according to EPA Reference Methods 2, 3,
3B, and 4 (40 CFR part 60, appendix A).
6. Monitoring Requirements
The rule requires an initial lead compound emission test for all
subject control devices to demonstrate compliance with the lead
compound emission standards. In addition, the rule requires annual
compliance testing for devices controlling process and process fugitive
emission sources. All owners and operators must also prepare SOP
manuals for the systematic inspection and maintenance of all baghouses,
and install and operate bag leak detection systems. Where required, a
single bagleak detector may be used to monitor a common stack serving
multiple baghouses. Each manual shall also include provisions for the
diagnosis of problems and a corrective action plan. Plans for
corrective action must prescribe procedures to be followed whenever an
alarm is triggered.
Compliance with the THC emission standards (except that for blast
furnace charging) will require monitoring either afterburner or
incinerator temperature or THC concentration. The THC emission limit
includes a carbon dioxide correction factor which accounts for dilution
(e.g., combining non-process streams, and tempering air). As such, the
THC monitor may be placed anywhere down stream of any organic HAP
control devices (e.g., after the baghouse). Only an initial compliance
test is required for blast furnace charging.
7. Notification Requirements
The owner or operator will be required to comply with the
notification requirements in the General Provisions to part 63 (40 CFR
part 60, subpart A). In addition, owners and operators will be required
to submit the fugitive dust control SOP and the baghouse SOP to the
Administrator for review and approval.
8. Recordkeeping and Reporting Requirements
Owners and operators will be required to comply with the
[[Page 32212]]
recordkeeping and reporting requirements in the General Provisions to
part 63 (40 CFR part 60, subpart A). In addition, the owners and
operators will be required to maintain records demonstrating that they
have implemented the requirements of the fugitive dust control SOP and
the baghouse SOP, including records of all bag leak detection system
alarms and corrective actions.
B. Summary of Changes Made Since Promulgation
The EPA has made several changes to the promulgated rule based on
comments contained in the petitions for reconsideration. A summary of
the changes is presented below. Additional discussion of the changes
and the rationale for these changes is presented in section II-C of
this preamble.
1. Definitions
Several definitions were revised or added to resolve issues and
clarify the intent of the rule. The definition of a bag leak detection
system was revised to specifically not exclude devices that operate on
the principle of light transmittance. Bag leak detection systems still
must meet the specifications outlined in Sec. 63.548(e).
A definition of collocated blast furnace and reverberatory furnace
was added. The new definition is based, in part, on the relative
exhaust rate for the blast furnace compared to the reverberatory
furnace. This definition was added in response to comments from two
smelters where the blast furnace exhaust was substantially higher than
the reverberatory furnace making commingling infeasible.
The definitions of secondary lead smelter and smelting were revised
and a definition of lead alloy was added to clarify that solder
reclamation operations are not subject to the rule.
The definitions of partial and total enclosure were revised to
clarify the intent of the rule. A definition of a high efficiency
particulate air (HEPA) filter was added for completeness.
2. Standards for Process Fugitive Sources
Section 63.544 was re-organized to clarify the intent of the rule
due to comments received. Specifically, the section was revised to make
it clear that a facility wishing to comply with the standard through
the use of a total enclosure may still use local hooding within the
total enclosure, and that a facility may choose to control some
fugitive emission sources with total enclosures and others through
enclosure hooding. These changes do not affect the requirements of the
rule.
The minimum doorway air velocity requirement for total enclosures
has been deleted. As revised, owners and operators choosing to control
process fugitive emission sources through total enclosures are required
to ventilate the building at a rate that would ensure in-draft at all
doorways. This requirement would replace the requirement for
maintaining an in-draft velocity of 250 meters per minute at all
doorways.
3. Test Methods and Schedule
The test method for demonstrating compliance with the hood face
velocity has been revised to address comments received in the
petitions. The current procedure could be read to require facilities to
test the hood face velocity with all access doors in the open position.
One petitioner argued that this requirement would, in many instances,
result in artificial operating conditions that would make compliance
impossible for certain operators. The rule is being revised to clarify
that facilities may demonstrate compliance with the access doors
positioned consistent with normal operation.
The test method for demonstrating compliance with the doorway air
velocity requirements has been revised to address comments received in
the petitions. As revised, owners and operators are given two options
for demonstrating that the enclosure is ventilated at a sufficient rate
to ensure in-draft at all openings. Under the first option, a vane
anemometer is placed in the center of each doorway to demonstrate that
air is being drawn into the building. Alternatively, an owner or
operator can elect to install a pressure gauge on the leeward wall of
the enclosure and demonstrate that the building is under a negative
pressure as compared to ambient pressure.
4. Monitoring Requirements
The minimum maintenance requirements specified in the rule have
been revised to address comments received in the petitions. The
frequency of several of the required inspections were lowered to reduce
the burden placed on operators. In addition, the requirements were
revised to allow for alternative means of inspection where appropriate
(e.g., fan vibration analysis in lieu of visual inspection for wear).
The specifications and requirements for bag leak detection systems
have been revised. The minimum detection capability of the bag leak
system was increased to 10 milligram per actual cubic meter from 1
milligram per actual cubic meter.
The requirement that a facility perform a compliance test in order
to adjust the settings on the bag leak detection system has been
dropped. Facilities will be allowed to adjust the bag leak detector as
provided in written EPA guidance or manufacturers written guidance in
the event EPA guidance is not available. In addition, annual compliance
tests have been instated.
The bag leak detection requirement for positive pressure baghouses
has been changed. Positive pressure baghouses equipped with stacks now
must meet the same bag leak detection system requirements as negative
pressure baghouses. None of the affected secondary lead smelters
currently operate any positive pressure baghouses without stacks, nor
are any expected to install such systems. Therefore positive pressure
baghouses without stacks are not addressed in the rule.
Facilities that have equipped their baghouses with HEPA filters as
a secondary filter to control emissions escaping the baghouse primary
filter are exempted from the bag leak detection requirements. However,
the facility must monitor the pressure drop across the HEPA filter, and
if the pressure drop falls outside of the limit(s) specified by the
filter manufacturer, the owner must take appropriate corrective
measures. Baghouses that are used to control emissions from total
enclosures used to comply with the fugitive dust standards
(Sec. 63.545) are also exempted from the bag leak detection
requirements.
5. Notification Requirements
The submittal date for the fugitive dust control SOP and the SOP
for baghouses has been extended by 30 days from June 23, 1997, to July
23, 1997. This extension is being made to allow owners and operators
adequate time to incorporate the changes being made in this revision
into their SOP manuals.
C. Summary of Environmental, Energy, Health, Cost, and Economic Impacts
The final standards, as amended, will reduce total nationwide
emissions of both metal HAP's and organic HAP's from secondary lead
smelters by 1,230 megagrams per year (Mg/yr) (1,356 tons/yr). These
reductions include 53 Mg/yr (58 tons/yr) of metal HAP's and 1,176 Mg/yr
(1,296 tons/yr) of organic HAP's. The organic HAP emission reduction
estimate has been reduced since promulgation by 54 Mg/yr (60 tons/yr).
This change is due to two facilities no longer meeting the definition
of a facility with a collocated blast furnace and reverberatory
furnace. The amendments made in today's action do
[[Page 32213]]
not significantly change the cost and economic impacts of the final
rule.
III. Public Participation
Following promulgation, the EPA received three petitions for
reconsideration from representatives of secondary lead smelters (Docket
ID Nos. IV-D-48, IV-D-49, and IV-D-50). The EPA met with the
petitioners to discuss the comments contained in the petitions.
Following the meeting, the petitioners provided the EPA with additional
information to support the comments made in the petitions (Docket ID
Nos. IV-D-51, and IV-D-52).
IV. Significant Public Comments and Responses
The EPA received three petitions to reconsider from owners and
operators of secondary lead smelters and industry trade associations.
Two of the three petitions contained multiple comments. A document that
summarizes the comments and arguments advanced in the petitions, and
the EPA responses, was prepared. The document, entitled ``Summary of
Petition Comments on Promulgated Rule and EPA Responses, Secondary Lead
Smelting NESHAP'', may be found in the docket (Docket ID No. V-B-2). It
serves as the basis for the revisions that have been made to the
standard since promulgation. This section contains a detailed
discussion of the significant comments contained in the petitions and
the EPA's responses. Significant comments and new information were
received on four topics: the definition of collocated blast and
reverberatory furnaces, test methods for determining hood face and
doorway air velocities, minimum baghouse SOP requirements, and bag leak
detection system specifications and requirements.
A. Definition of Collocated Blast Furnace and Reverberatory Furnaces
Comment: Two petitioners (Docket ID Nos. IV-D-49, and IV-D-50)
requested reconsideration of the THC limit for collocated blast
furnaces and reverberatory furnaces. One petitioner (Docket ID No. IV-
D-49) indicated that their blast furnace was originally designed as a
primary lead blast furnace, and as such, had an exhaust rate 10 times
higher than typical secondary lead blast furnaces. The high blast
furnace exhaust rate compared to their low reverberatory exhaust rate
made commingling technically and economically infeasible. The petition
supplied information to support the claim.
The second petitioner (Docket ID No. IV-D-50) pointed out that the
term ``collocated'' was not defined, and argued that smelter
configurations very dramatically. They identified one facility that
would have difficulty meeting the requirements since they had two blast
furnaces and only one reverberatory furnace. Upon request, the
petitioner supplied the exhaust flowrates for the two blast furnaces
(25,300 scfm, total) and the reverberatory furnace (8,800 scfm) (Docket
ID No. IV-D-52).
Response: The EPA reviewed the requests and the additional
information provided by the petitioners. The EPA evaluated the
differences in furnace exhaust rates for facilities with blast and
reverberatory furnaces (Docket ID No. II-B-36). Information on the
exhaust rates was obtained for all eight of the existing facilities
with both blast and reverberatory furnaces. On reviewing the
information, two groupings of facilities were evident. Six of the
facilities had blast furnace exhaust rates which were less than roughly
half that of the reverberatory exhaust rate. In contrast, two
facilities had blast furnace exhaust rates which are more than 150
percent of the reverberatory exhaust rate. These two facilities, Doe
Run, Missouri; and Schuylkill, Louisiana, are the facilities
represented in the petitions.
Commingling of the exhaust gases is the basis for the collocated
blast furnace and reverberatory furnace THC emission limit. The
principle of commingling the exhaust gases is based on a large hot
(2000+ degree Fahrenheit) reverberatory furnace exhaust acting as the
principle heat source to incinerate any organics in the smaller cooler
(roughly 200 deg.F) blast furnace exhaust. Clearly this condition is
not met at the two facilities represented in the petitions. As such, it
is unlikely that these two facilities would be able to achieve the THC
standard for collocated blast furnaces and reverberatory furnaces by
commingling, nor is it likely that they could achieve the standard
through the use of afterburners.
To correct this situation, the EPA is adding the following
definition of collocated blast furnace and reverberatory furnace to the
final rule:
``Collocated blast furnace and reverberatory furnace means
operation at the same location of a blast furnace and a
reverberatory furnace with the volumetric flow rate discharged from
the blast furnace equal to or less than that discharged from the
reverberatory furnace.''
Under this definition, the two facilities represented in the
petition would not be classified as having a collocated blast furnace
and reverberatory furnace. As such, their blast furnaces would be
subject to the blast furnace THC limit of 360 ppmv as propane rather
than the 20 ppmv limit for collocated furnaces.
B. Test Methods for Determining Hood Face and Doorway Air Velocities
Comment: One petitioner (Docket ID No. IV-D-50) objected to the
requirements in the rule for demonstrating compliance with the hood
face air velocity standard. Specifically, the petitioner objected to
the requirement that all access doors to a hood be open when measuring
hood face velocity. The petitioner noted that at least one smelter has
a charging hood with two doors to allow charging from either direction,
but only one is open at any one time. In addition, the petitioner
pointed out that some of the doors are used solely for the purpose of
allowing periodic access for maintenance and other necessary
activities. The petitioner argues that the requirement may render
compliance with the face velocity standard impossible for certain
operators, and does so unnecessarily because it does not reflect normal
operations.
Response: The intent of the requirements is to ensure that adequate
capture velocities are maintained during normal operating conditions.
The EPA did not intend to require compliance demonstrations during
artificial ``worst case'' operating conditions. As such, the EPA is
revising Sec. 63.547(d) to clarify the rule's intent.
Each access door and opening open during normal operation shall be
tested. When a given access door is being tested, all other access
doors shall be in the position they would be in during normal
operation.
Comment: Two petitioners commented on the requirements for
demonstrating compliance with the doorway air velocity standard for
total enclosures. One petitioner (Docket ID No. IV-D-50) noted that the
requirement could be read to mean that all doors that might be open
during normal operation be open simultaneously during testing,
regardless of whether such conditions occur during normal operations. A
second petitioner (Docket ID No. IV-D-48) also commented that the rule
was ambiguous on where and how the compliance with the air velocity
requirement is to be measured. The petitioner also noted concern about
the acheivability of the 250 feet per minute air velocity requirement.
Both petitioners noted that requirements on doorway air velocities were
not contained in the proposed rule, and that the industry did not have
an
[[Page 32214]]
opportunity to comment on the requirements.
Response: The EPA's intent was to require adequate ventilation to
ensure air flow into the building at all doorways during normal
operation conditions. Upon further consideration, the EPA believes that
the 250 foot per minute doorway velocity requirement is excessive for
this purpose, and would result in undue burden to the industry. As
such, the EPA is revising the requirement. As revised, a facility must
ventilate the building to a rate that ensures air flow is into the
building at all doorways that would be open during normal operation.
Two alternative methods are provided for demonstrating compliance.
Owners and operators can choose to demonstrate in-draft at each door
using a vane anemometer, or may install a pressure gauge on the leeward
wall to demonstrate that the building is maintained at a lower than
ambient pressure.
C. Minimum Baghouse SOP Requirements
Comment: One petitioner (Docket ID No. IV-D-50) commented on the
minimum requirements for the baghouse inspection and maintenance SOP.
While agreeing that an appropriate inspection and maintenance program
is critical to monitoring performance, they argued that the minimum
requirements set forth by the rule were unrealistic and unnecessary in
some cases. The petitioner indicated that the EPA underestimated the
labor required to satisfy the minimum requirements. The petitioner also
argued that frequent baghouse inspections would result in increased
fugitive emissions (due to wear on door seals) and worker exposure.
Response: The EPA has reviewed the minimum requirements for the
baghouse inspection and maintenance SOP, and the labor estimates
provided by the petitioners. The labor estimates to complete the
minimum inspection requirements are significantly higher than
previously estimated. The EPA has revised Sec. 63.548(c) to reflect a
more realistic schedule. In addition, several of the requirements have
been reworded to allow for alternatives to visual inspections where
appropriate. The revised requirements, which still include continuous
bag leak detection, will reduce the labor burden associated with
baghouse inspections while still providing adequate protection of the
environment.
D. Bag Leak Detection System Specifications and Requirements
Comment: Two petitioners (Docket ID No. IV-D-48, and IV-D-50)
commented on the rules requirement that a compliance test be performed
after any adjustments to the required bag leak detectors are made. One
petitioner (Docket ID No. IV-D-48) stated that this requirement does
not reflect the realities of normal operations and, as such, may cause
unacceptable difficulties in practice. They further stated that all
measurement instruments require calibration on a routine basis, with
the calibration interval dependent upon the instrument's sensitivity
and detection requirements. Without such sensitivity adjustments, the
presence of drift may cause the system to operate improperly. The
second petitioner (Docket ID No. IV-D-50) echoed the need for periodic
adjustments to account for drift. They also commented that the
requirement tying the adjustment to compliance testing ignores the
actual operation of bag leak detectors. Because there is no set
relationship between the particulate emissions, as measured by the
unit, and lead emission levels, the bag leak detector is not a monitor
of lead emissions. Rather, its purpose is to reveal bag leaks.
Response: Upon further consideration, the EPA agrees that periodic
adjustment of the bag leak detector system may be necessary, and that
adjustment of the bag leak detector should not be tied to compliance
demonstrations. The intended use of the bag leak detector was as a
process monitor, able to identify upset conditions in the baghouse
operation. The EPA is concerned however, that unrestricted adjustment
of the bag leak detector could result in improper use, possibly
resulting in the alarm and sensitivity settings being set such that
leaks or malfunctions could occur undetected. As such, the EPA has
revised the bag leak system adjustment requirements to: (1) delink bag
leak detector adjustment and compliance testing, (2) allow for routine
minor adjustments to the detector system, (3) require owners and
operators to identify in their baghouse SOP all routine adjustments
expected, and (4) require that owners and operators perform a complete
baghouse inspection to ensure proper operation of the baghouse prior to
any significant adjustments to the sensitivity or range.
In addition, a requirement for annual compliance testing has been
instated. Instating annual compliance testing should not result in a
significant increase in compliance testing costs over those imposed in
the promulgated rule. The EPA assumed that facilities would wish to
adjust bag leak detection settings at least once a year, which as
written, would have triggered compliance testing.
Comment: One petitioner (Docket ID No. IV-D-48) argued that the bag
leak detection system detection capability requirement is too
restrictive. Section 63.548(e)(1) requires that the bag detection
system be able to detect emissions of particulate matter at 1.0
milligram per actual cubic meter or less. The petitioner argues that,
since the bag leak detector system monitors PM rather than lead, the
specification does not correlate to the emission limit in the rule.
They also argue that the specification is unnecessary to ensure that a
bag leak detection system is capable of detecting tears and/or leaks in
baghouse bags. Furthermore, the petitioner noted concern that the
specification is based on information provided by only one manufacturer
of one type of bag leak detector.
Response: The EPA did not intend to tie the bag leak detector
detection capability to the lead limit. The intent of the requirement
was to set a minimum detection capability to ensure a minimum quality
and capability of the detection systems to be used. Bag leak detection
systems were being used at several secondary lead smelters. The
detection capability was set based on what was believed to be the
detection capability of the systems already being used at these
smelters. Upon further review it was determined that the 1.0 milligram
per actual cubic meter detection capability was actually the capability
of the most sensitive bag leak detectors available, and was not
representative of the bag leak detectors already in use at secondary
lead smelters. The EPA is increasing the detection capability to 10
milligram per actual cubic meter which is more representative of the
existing bag leak detectors, and still meets the EPA's purpose of
ensuring systems capable of detecting baghouse upset conditions.
Comment: One petitioner (Docket ID No. IV-D-48) commented that some
baghouses are equipped with HEPA filters. The petitioner believes that
it is unnecessary and impractical to require bag leak detection systems
for these units, and that requiring visual inspections of the HEPA
units and review of operating readouts in accordance with an approved
SOP is fully protective of human health and the environment.
Response: The EPA acknowledges that some baghouses are equipped
with HEPA filters which act as a secondary
[[Page 32215]]
filter, and that these secondary filters may provide improved
protection from bag leaks. The EPA also agrees that the use of a bag
leak detector on such a system would likely provide little if any
additional protection over proper inspection and monitoring of
operating parameters (such as pressure drop). As such, the EPA is
adding Sec. 63.548(g) to exempt baghouses equipped with secondary HEPA
filters from the bag leak detection requirement and add alternative
monitoring requirements for these systems.
Comment: One commenter (Docket ID No. IV-D-50) argued that the
requirement for bag leak detectors on all baghouses for process,
process fugitive, and fugitive emissions is excessive. They contend
that there are applications, particularly baghouses used to control
particulate from building ventilation, in which units will not function
due to the nature of the particulate.
Response: Upon further review, the EPA agrees that bag leak
detectors will provide little to no useful information on baghouses
used to control fugitive dust emissions from building ventilation. This
is due to the low inlet loadings associated with these systems. As
such, the EPA is adding Sec. 63.548(h) to exempt baghouses used to
control fugitive dust emissions from the bag leak detection
requirement. Owners and operators are still required to develop and
adhere to a SOP for the operation and maintenance of these baghouses
that meets the minimum requirements specified in Sec. 63.548(c).
V. Administrative Requirements
A. Docket
The docket is an organized and complete file of all the information
considered by the EPA in the development of this rulemaking. The docket
is a dynamic file, since material is added throughout the rulemaking
development. The docket system is intended to allow members of the
public and affected industries to readily identify and locate documents
so that they can effectively participate in the rulemaking process.
Along with the BID's and preambles to the proposed and promulgated
standards, the contents of the docket will serve as the official record
in case of judicial review (section 307(d)(7)(A) of the Act).
B. Executive Order 12866
The Agency must determine whether a regulatory action is
``significant'' and therefore subject to OMB review and the
requirements of the E.O. 12866, (58 FR 51735, October 4, 1993). The
Executive 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 amendment to the final rule is not
a ``significant regulatory action'' under the terms of the Executive
Order and is therefore not subject to OMB review.
C. Unfunded Mandates Act
Section 202 of the Unfunded Mandates Reform Act of 1995 (``Unfunded
Mandates Act'') requires that the Agency prepare a budgetary impact
statement before promulgating a rule that includes a Federal mandate
that may result in expenditure by State, local, and tribal governments,
in aggregate, or by the private sector, of $100 million or more in any
1 year. Section 203 requires the Agency to establish a plan for
obtaining input from and informing, educating, and advising any small
governments that may be significantly or uniquely affected by the rule.
Under section 205 of the Unfunded Mandates Act, the Agency must
identify and consider a reasonable number of regulatory alternatives
before promulgating a rule for which a budgetary impact statement must
be prepared. The Agency must select from those alternatives the least
costly, most cost-effective, or least burdensome alternative that
achieves the objectives of the rule, unless the Agency explains why
this alternative is not selected or the selection of this alternative
is inconsistent with law.
This amendment reduces the costs of complying with the final rule,
it will not increase expenditures by State, local, and tribal
governments or the private sector. Therefore, the Agency has not
prepared a budgetary impact statement or specifically addressed the
selection of the least costly, most cost-effective, or least burdensome
alternative. Because small governments will not be significantly or
uniquely affected by this rule, the Agency is not required to develop a
plan with regard to small governments.
D. Paperwork Reduction Act
Under the Paperwork Reduction Act, 44 U.S.C 3501 et seq., the EPA
must consider the paperwork burden imposed by any information
collection request in a proposed or final rule. This amendment to the
rule will not impose any new information collection requirements.
E. Regulatory Flexibility Act
The Regulatory Flexibility Act (or RFA, Public Law 96-354,
September 19, 1980) requires Federal agencies to give special
consideration to the impact of regulation on small businesses. The RFA
specifies that a regulatory flexibility analysis must be prepared if a
screening analysis indicates a regulation will have a significant
economic impact on a substantial number of small entities. EPA has
determined that it is not necessary to prepare a regulatory flexibility
analysis in connection with this final rule. EPA has also determined
that this rule will not have a significant economic impact on a
substantial number of small entities. This amendment will not result in
increased economic impacts to small entities, and will result in
reduced impacts in all cases.
F. Submission to Congress and the General Accounting Office
Under 5 U.S.C. 801(a)(1)(A) as added by the Small Business
Regulatory Enforcement Fairness Act of 1996, the EPA submitted 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
General Accounting Office prior to publication of the rule in today's
Federal Register. This amendment is not a ``major rule'' as defined by
5 U.S.C. 804(2).
