National Emission Standards for Hazardous Air Pollutants for
Petroleum Refineries: Catalytic Cracking Units, Catalytic Reforming
Units, and Sulfur Recovery Units

AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule.

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

SUMMARY: This action establishes final national emission standards for
hazardous air pollutants (NESHAP) for certain types of affected sources
at petroleum refineries. The affected sources include catalytic
cracking units (CCU), catalytic reforming units, and sulfur recovery
units, as well as associated by-pass lines. The EPA has identified
petroleum refineries as major sources of hazardous air pollutants
(HAP). Hazardous air pollutants that would be reduced by this final
rule include organics (acetaldehyde, benzene, formaldehyde, hexane,
phenol, toluene, and xylene); reduced sulfur compounds (carbonyl
sulfide, carbon disulfide); inorganics (hydrogen chloride, chlorine);
and particulate metals (antimony, arsenic, beryllium, cadmium,
chromium, cobalt, lead, manganese, and nickel). The health effects of
exposure to these HAP can include cancer, respiratory irritation, and
damage to the nervous system. These final standards implement section
112(d) of the Clean Air Act (CAA) by requiring all petroleum refineries
that are major sources to meet standards reflecting the application of
the maximum achievable control technology (MACT). When fully
implemented, this rule will reduce HAP emissions from the affected
sources by nearly 11,000 tons per year tpy--an 87 percent reduction
from current levels. Emissions of other pollutants such as volatile
organic compounds (VOC), particulate matter (PM), carbon monoxide (CO),
and hydrogen sulfide will be reduced by about 60,000 tpy.

EFFECTIVE DATE: April 11, 2002.

I. Background

The CAA was created in part to protect and enhance the quality of
the Nation's air resources to promote public health and welfare and the
productive capability of its population. Section 112(d) of the CAA
requires us (the EPA) to establish standards for all categories and
subcategories of major sources of HAP and for area sources listed for
regulation under section 112(c). Major sources are those that emit or
have the potential to emit at least 10 tpy of any single HAP or 25 tpy
of any combination of HAP. Area sources are stationary sources of HAP
that are not major sources.
We received 40 public comments on the proposed NESHAP. Commenters
included industry representatives and trade associations, State and
local agencies, environmental groups, vendors, and technical experts.
To provide interested individuals the opportunity for oral
presentations of data, views, or arguments concerning the proposed
rule, we held a public hearing on October 14, 1998, and extended the
end of the public comment period from November 10, 1998, to December 1,
1998 (Docket A-97-36). Today's final rule reflects our full
consideration of all the comments we received. Major public comments on
the proposed rule along with our responses to these comments are
summarized in this document. See the Response to Comment Document
(Docket A-97-36) for detailed responses to all the comments.

II. Summary of Final Rule and Changes Since Proposal

We revised the overall format of the rule to make it easier to
understand, implement, and enforce. Separate sections of this ``plain
language'' final rule cover the requirements for each type of HAP
(i.e., metal HAP, organic HAP, inorganic HAP, or overall HAP) from an
affected source. Each section of the rule refers you (the refinery
owner or operator) to tables at the end of the rule that list the
specific rule requirements and give step-by-step instructions on how to
demonstrate initial and continuous compliance.
For purposes of the final rule, the title has been changed to
``National Emission Standards for Hazardous Air Pollutants for
Petroleum Refineries: Catalytic Cracking Units, Catalytic Reforming
Units, and Sulfur Recovery Units'' to better describe the affected
population. The source category list will be amended to reflect this
name change in a separate action.
In the past year, six petroleum refining companies have signed
voluntary settlements with EPA which will add controls for CCU and SRU
that will comply with this final rule. We have not revised the impact
estimates to reflect the controls resulting from these settlements.

A. Who Must Comply With This Rule?

The final rule (subpart UUU) applies to you if your petroleum
refinery is a major source of HAP emissions and includes an affected
source covered by the rule. Based on our data, we believe all 164
existing petroleum refineries in the U.S. and its territories are major

[[Page 17764]]

sources; 132 of these facilities have one or more of the affected
sources subject to the rule requirements.

B. What Equipment Is Covered?

Section 63.1562 of the final rule identifies each type of affected
source as well as equipment or processes not covered by the rule. As
proposed, three types of existing, new, or reconstructed units are
subject to the rule. These are:
Each CCU that regenerates catalyst;
Each catalytic reforming unit that regenerates catalyst;
and
Each sulfur recovery unit and the tail gas treatment unit
serving it.
The rule also applies to each by-pass line serving a new, existing,
or reconstructed affected source. We have clarified the applicability
of the rule to emphasize that the unit is the affected source while the
emission limits and standards apply to the specified type of vent
associated with the unit.
The final rule applies only to the predominant type of CCU--those
using a fluidized bed (i.e., fluid CCU). We also revised the
applicability of the rule to exclude redundant sulfur recovery units
not located at a petroleum refinery and used by the refinery only for
emergency or maintenance backup. Consistent with the proposed rule, the
final rule doesn't apply to a sulfur recovery unit that doesn't recover
elemental sulfur, certain equipment associated with by-pass lines
(i.e., low leg drains, high point bleeds, analyzer vents, open-ended
valves or lines, or pressure relief valves needed for safety reasons),
or gaseous streams routed to a fuel gas system.

C. When Must I Comply?

Section 63.1563 of the final rule gives the compliance dates. As
discussed further in section IV.A of this document, we have included
provisions allowing an extended compliance date for existing fluid CCU
located at a petroleum refinery that commits to hydrotreating the CCU
feed to comply with the gasoline sulfur control requirements in the
Tier 2 Motor Vehicle Emission Standards (40 CFR part 80) and the
applicable emission limitations in subpart UUU. The compliance date for
these existing affected sources will depend on when the refinery must
meet the 30 parts per million (ppm) limit for gasoline sulfur content,
but can't be any later than December 31, 2009. Otherwise, affected
sources must comply within 3 years from today's date.
We also clarified the compliance dates for new or reconstructed
affected sources. If you started your new or reconstructed affected
source before today's date, you must comply with the applicable rule
requirements by today. If you start your new or reconstructed affected
source after today's date, you must comply with the rule requirements
upon startup.

D. What Are the Emission Limitations and Other Standards?

The final rule includes emission limitations for HAP emissions of
particulate metals and organic compounds from CCU, organic and
inorganic compounds from catalytic reforming units, and reduced sulfur
compounds from sulfur recovery units. An emission limitation means any
emission limit, operating limit, opacity limit, or visible emissions
limit. Surrogates are used in this rule to represent the HAP emissions.
They allow easier, less expensive measurement and monitoring
requirements. For CCU, PM and nickel (Ni) are used as surrogates for
metal HAP. Carbon monoxide is used as a surrogate for organic HAP
emissions. Total organic carbon (TOC) is a surrogate for organic HAP
emissions from catalytic reforming units while hydrogen chloride (HCl)
represents inorganic HAP emissions. Sulfur dioxide (SO₂) or
total reduced sulfur (TRS) represent the reduced sulfur HAP emissions
from sulfur recovery units.
We made no changes in the MACT floor determinations of control
technologies serving as the basis of the proposed rule. The emission
control technologies and limits are discussed in the preamble to the
proposed NESHAP (63 FR 48890). However, we did revise in other respects
the emission limitations and standards that reflect the performance of
the MACT floor technologies.
In response to public comments, we clarified the requirements for
affected sources also subject to the new source performance standard
(NSPS) for petroleum refineries (40 CFR part 60, subpart J) and added
new compliance options. If your affected source is also subject to the
NSPS, complying with the NSPS emission limitations also allows you to
comply with this rule. If your affected source isn't subject to the
NSPS, you can elect to comply with the NSPS emission limitations in
order to be in compliance with this rule.
As further discussed in section IV.B of this document, we also
added a second Ni limit as another metal HAP compliance option for CCU.
This alternative provides an emission limit formatted to account for
the variable characteristics of these units. We added it to the rule
both to credit and encourage hydrotreating of the CCU feed as a means
of reducing metal HAP emissions to the atmosphere.
We also made a change to the TOC emission limit for catalytic
reforming units in Sec. 63.1562(b)(1)(iii) of the proposed rule. This
provision exempted emissions during depressuring and purging operations
if the reactor vent pressure or differential pressure between the
reactor vent and the gas transfer system to the control device were
under 1 pound per square inch gauge (psig). Since 5 psig is the limit
in States with facilities representing the MACT floor, we revised this
provision to state that the emission limitations do not apply to
depressuring and purging when the reactor vent pressure is 5 psig or
less.
The final rule also includes specific operating limits for
monitored process or control device operating parameters. Operating
limits also may apply if you choose to comply with certain options,
such as the alternative Ni emission limitations for CCU.
Tables 1, 2, 8, and 9 to the final rule (subpart UUU) show the
final emission limitations for CCU. Tables 15, 16, 22, and 23 to
subpart UUU give the emission limitations for catalytic reforming
units. The final emission limitations for sulfur recovery units are in
Tables 29 and 30 to subpart UUU.
The final rule also includes work practice standards for HAP
emissions from by-pass lines. A work practice standard may include a
design, equipment, work practice, or operational requirement. Table 36
to subpart UUU lists the four options provided under the final rule.
The final rule also includes work practice standards for all affected
sources. These standards require you to prepare an operation,
maintenance, and monitoring plan according to the rule requirements and
comply with the procedures in the plan. This plan must be consistent
with good air pollution control practices for minimizing emissions.

E. How Do I Demonstrate Initial Compliance?

You must install and operate the required continuous monitoring
systems and show that you meet each emission limitation or work
practice standard that applies to you. The requirements for
demonstrating initial compliance differ by unit type and according to
whether or not your affected source is also subject to the NSPS
requirements.
If your CCU or sulfur recovery unit is also subject to the NSPS,
you must meet the applicable emission limitations and monitoring
requirements in this rule. These requirements in this case are the same
as the NSPS. If you have already

[[Page 17765]]

done a performance test to demonstrate initial compliance with the
NSPS, you aren't required to do another test to demonstrate initial
compliance with the limits in this rule. If you have already done a
performance test, you aren't required to do another one to show that
your continuous opacity and emission monitoring systems meet the
applicable performance specifications. You can demonstrate initial
compliance for these affected sources by submitting a written statement
in your Notification of Compliance Status certifying that you comply
with the applicable NSPS requirements.
We have revised the requirements for affected sources not subject
to the NSPS to account for the new compliance options, as well as
revisions to monitoring requirements. Your requirements for
demonstrating initial compliance will vary according to the compliance
option you elect and the type of continuous monitoring system you must
use.
1. HAP Metal Emissions From CCU
If you elect to comply with the NSPS, you must install and operate
a continuous opacity monitoring system to measure and record the
opacity of emissions from each catalyst regenerator vent. The final
rule also requires a continuous opacity monitoring system if your CCU
has a fresh feed capacity of 20,000 barrels per day (or more) and uses
an add-on control device other than a wet scrubber (e.g., an
electrostatic precipitator) to control the catalyst regenerator vent
emissions. You also must install and operate a continuous opacity
monitoring system if your CCU isn't equipped with an add-on control
device. If you use a continuous opacity monitoring system and elect to
comply with either of the Ni limits, you also must install and operate
a continuous parameter monitoring system to measure and record the gas
flow rate. Or, you can use the approved alternative procedure in the
final rule to determine the gas flow rate.
For a smaller CCU (fresh feed capacity 20,000 barrels per day or
less) that uses an electrostatic precipitator to control emissions from
the catalyst regenerator vent, you can use a continuous opacity
monitoring system (with a continuous monitoring parameter system for
gas flow rate if you elect either of the Ni options) or continuous
parameter monitoring systems. The continuous parameter monitoring
systems must measure and record the gas flow rate as well as the
voltage and secondary current (or total power input).
If you use a wet scrubber to control emissions from your catalyst
regenerator vent, you must use continuous parameter monitoring systems
to measure and record the pressure drop across the scrubber, the gas
flow rate, and the total liquid (or scrubbing liquor) flow rate,
regardless of unit capacity. In response to comments, we exempted non-
Venturi wet scrubbers of the jet-ejector design from monitoring
requirements and operating limits for pressure drop.
Section 63.1573 of the final rule provides approved alternative
monitoring procedures. If applicable, you can use these alternative
procedures to determine the gas flow rate rather than a continuous
parameter monitoring system.
You must prepare a site-specific test plan and do a performance
test to demonstrate initial compliance with the applicable emission
limitation(s). If you use a continuous opacity monitoring system and
elect to meet the NSPS, you also must do a site-specific performance
evaluation test plan and performance evaluation to show that your
monitoring system meets the applicable performance specification.
If you use a continuous opacity monitoring system and elect the PM
limit, you must use the performance test results to establish a site-
specific opacity operating limit. If you elect either Ni limit, you
must use the performance test results to establish a site-specific Ni
operating limit based on opacity, gas flow rate, equilibrium catalyst
Ni concentration, and coke burn-rate (depending on the format of the
option you elect). You can use EPA Method 6010b, 6020, 7520, or 7521 in
``Test Methods for Evaluating Solid Waste, Physical/Chemical Methods,''
EPA Publication SW-846, Revision 5 (April 1998) or an alternative
method satisfactory to the Administrator to analyze the equilibrium
catalyst Ni concentration. The final rule includes procedures for
establishing each type of operating limit.
If you use continuous parameter monitoring systems for an
electrostatic precipitator and elect the PM emission limitation, you
must use the performance test results to establish operating limits for
gas flow rate and voltage and secondary current (or total power input).
If you elect either of the Ni limits, you must establish operating
limits for the equilibrium catalyst Ni concentration. If you use a wet
scrubber, you must use the performance test results to establish
operating limits for pressure drop and liquid-to-gas ratio (if you
elect the PM limit) as well as equilibrium catalyst Ni concentration
(if you elect either of the Ni limits).
Table 3 to subpart UUU shows the requirements for continuous
monitoring systems for HAP metal emissions from CCU. Table 4 to subpart
UUU shows the performance test requirements under each of the four
compliance options. You have demonstrated initial compliance with the
metal HAP emission limitations if you meet the conditions in Table 5 to
subpart UUU.
2. Organic HAP Emissions From CCU
Table 10 to subpart UUU shows the requirements for continuous
monitoring systems for organic HAP emissions from CCU. If you elect to
comply with the NSPS requirements, you must install and operate a
continuous emission monitoring system to measure and record the
concentration by volume (dry basis) of CO emissions from each catalyst
regenerator vent.
If you don't elect to comply with the NSPS requirements, you must
use continuous parameter monitoring systems. In response to comments,
we have revised the proposed requirements for thermal incinerators to
include a continuous parameter monitoring system to measure and record
the oxygen content (percent dry basis) in the incinerator vent stream
as well as the combustion zone temperature. If your unit is not
equipped with a combustion control device, the final rule requires that
you use a continuous emission monitoring system. Like the NSPS, if you
can demonstrate that emissions from your vent average 50 ppm or less,
the final rule does not require a continuous emission monitoring system
or a continuous parameter monitoring system.
To demonstrate initial compliance, you must prepare a site-specific
test plan and do a performance test to show that your vent meets the
emission limit. If you use a continuous emission monitoring system and
elect to comply with the NSPS, you also must prepare a site-specific
performance evaluation test plan and do a performance evaluation to
show that your system meets the applicable performance specification.
If you use continuous parameter monitoring systems, you must use
the test results to establish operating limits for combustion zone
temperature and oxygen concentration in the vent stream. We also
clarified the performance test provisions for flares, which require a
visible emissions test by Method 22 with a 2-hour observation period.
Table 11 to subpart UUU shows the performance test requirements for
organic HAP emissions. You have demonstrated initial compliance with

[[Page 17766]]

the organic HAP emission limits if you meet the conditions in Table 12
to subpart UUU.
3. Organic HAP Emissions From Catalytic Reforming Units
Table 17 to subpart UUU shows the continuous monitoring system
requirements for organic HAP emissions from catalytic reforming units.
We didn't revise the proposed requirements for continuous monitoring
systems for these units.
To demonstrate initial compliance, you must prepare a site-specific
test plan and do a performance test to show that your vent meets the
applicable emission limitation. We revised the proposed performance
test procedures to remove Method 18 (40 CFR part 60, appendix A) for
measurement of TOC concentration. You can use Method 25 or 25A for TOC
concentration. We also clarified the requirements for flares (see
section II.E of this document). Using the performance test results, you
must establish operating limits for the combustion zone temperature of
your combustion control device. Table 18 to subpart UUU shows the
performance test requirements. You have demonstrated initial compliance
with the emission limitations if you meet the conditions in Table 19 to
subpart UUU.
4. Inorganic HAP Emissions From Catalytic Reforming Units
Table 24 to subpart UUU shows the continuous monitoring system
requirements for inorganic HAP emissions from catalytic reforming
units. We revised the proposed requirements for wet scrubbers to
include a continuous parameter monitoring system to measure and record
the pH of the water (or scrubbing liquid) exiting the scrubber instead
of a continuous parameter monitoring system for pressure drop. You can
also use the approved monitoring alternative for pH strips in lieu of a
continuous parameter monitoring system. We also revised the proposed
rule to include requirements for units with an internal scrubbing
system (i.e., no add-on control device) based on use of colormetric
tube sampling systems.
Table 25 to subpart UUU shows the performance test requirements for
inorganic HAP emissions from catalytic reforming units. You must
prepare a site-specific test plan and do a performance test to show
that you meet the applicable emission limitation. We revised the
proposed performance test requirements to specify that you can't make
any test runs during the first hour or the last 6 hours of the cycle
for a semi-regenerative or cyclic regeneration unit. Using the results
of the performance test, you must establish operating limits for the
liquid-to-gas ratio and pH of the scrubber water (or scrubbing liquid).
If you don't use a control device, you must establish an operating
limit for the HCl concentration using colormetric tubes. You can use
Method 26 in 40 CFR part 60, appendix B, to measure emissions from
these units. You have achieved initial compliance with the inorganic
HAP emission standards if you meet the conditions in Table 26 to
subpart UUU.
5. Organic HAP Emissions From Sulfur Recovery Units
Table 31 to subpart UUU shows the continuous monitoring system
requirements for organic HAP emissions from sulfur recovery units. If
you elect to comply with the NSPS requirements, you must install and
operate a continuous emission monitoring system to measure and record
the concentration (dry basis, zero percent excess air) of SO2 emissions
exiting each exhaust stack for the unit if you use an oxidation or
reduction control system followed by incineration. If you use a
reduction control system without incineration, you must use continuous
emission monitoring systems to measure and record the concentration of
reduced sulfur and oxygen emissions. If you elect to comply with the
TRS limit and use an incinerator to control emissions from your vent,
you must install and operate a continuous emission monitoring system or
a continuous parameter monitoring system to measure and record the
combustion zone temperature and the oxygen content (percent, dry basis)
in the vent stream of the incinerator. If you do not use an add-on
control device to control emissions from your vent, you must install
and operate a continuous emission monitoring system to measure and
record the concentration of TRS.
You must prepare a site-specific test plan and do a performance
test to show that emissions from your vent meet the applicable
standard. If you use a continuous emission monitoring system and elect
to meet the NSPS, you also must do a site-specific performance
evaluation test plan and a performance evaluation to show that your
system meets the applicable performance specification. If you use
continuous parameter monitoring systems, you must establish operating
limits for oxygen concentration as well as for combustion zone
temperature. Table 32 to subpart UUU shows the performance test
requirements for each option. You have demonstrated initial compliance
if you meet the conditions specified in Table 33 to subpart UUU.
6. HAP Emissions From Bypass Lines
We revised the proposed standards for by-pass lines to include two
new equipment options suggested by commenters. Table 37 to subpart UUU
shows the performance test requirement applicable to a flow indicator,
level recorder, or electronic valve position monitor. You have achieved
initial compliance if you meet the applicable conditions for the work
practice option you select shown in Table 38 to subpart UUU.
7. Continuous Monitoring System Requirements
We added new sections (Secs. 63.1572 and 63.1573) to the final rule
to clearly identify the requirements for monitor installation and
operation and monitoring alternatives. Table 40 to subpart UUU shows
the requirements for continuous opacity monitoring systems and
continuous emission monitoring systems, which are the same as the NSPS.
Table 41 to subpart UUU shows the requirements for installation and
operation of continuous parameter monitoring systems. We have revised
these requirements to include more detailed requirements for
inspections and calibration checks as well as performance
specifications for some types of systems. We also revised the rule to
clarify that each continuous parameter monitoring system must measure
and record on an hourly or hourly average basis and determine and
record the daily average value.
The final rule also specifies that you operate your monitors (or
collect data at all required intervals) at all times the affected
source is operating. This does not apply to monitoring malfunctions,
associated repairs, required quality assurance or control activities,
and preapproved planned maintenance activities. You may not use data
recorded during monitoring malfunctions, associated repairs, and
required quality assurance or control activities in data averages and
calculations or to meet a minimum data availability requirement.
8. Performance Tests, Performance Evaluations, and Engineering
Assessments
Section 63.1571 of the final rule contains general information and
criteria you must meet for these activities. We have clarified the rule
to specify that you can do your performance test at any time from
today's date to your compliance date. In response to comments, we
revised

[[Page 17767]]

Sec. 63.1564(e) of the proposed rule to require that the tests be done
under normal operating conditions rather than at ``maximum
representative operating capacity for the process.'' You must base your
process or control device operating limits on the performance test
measurements. However, unless you elect one of the two Ni options for
metal HAP emissions from CCU, you can adjust the measured values, if
necessary, using control device design specifications, manufacturer
recommendations, or other applicable data. You must document any
adjustment to the satisfaction of your permitting authority. We added
special provisions to the rule for adjusting the Ni-related values.
This section of the rule also covers how to change your operating
limit. While you can change your site-specific opacity operating limit
or Ni operating limit only by doing a new performance test, you can
change other operating limits for continuous parameter monitoring
systems by doing another performance test, a performance test in
conjunction with an engineering assessment, or by an engineering
assessment. You must establish a revised limit if you make any change
in the process or operating conditions that could affect control system
performance or if you change the designated conditions after the last
performance or compliance tests were done.

F. How Do I Demonstrate Continuous Compliance?

A new section, Sec. 63.1570, of the final rule states your general
requirements for complying with this rule. You must be in compliance
with all of the non-opacity emission limits during the times specified
in Sec. 63.6(g)(1). You must be in compliance with the opacity emission
limits during the times specified in Sec. 63.6(h)(1). You must always
operate and maintain your affected source, including air pollution and
control and monitoring equipment, according to the provisions in
Sec. 63.6(e)(1)(i).
Subpart UUU requires that you develop and implement a startup,
shutdown, and malfunction plan according to the requirements in
Sec. 63.6(e)(3). During periods of startup, shutdown, or malfunction,
you must operate your affected source and control equipment according
to your plan.
You must report each instance in which you did not meet each
emission limitation or work practice standard that applies to you. This
includes periods of startup, shutdown, and malfunction. These instances
are deviations from the emission limitations and work practice
standards that must be reported according the requirements in
Sec. 63.1575 of the final rule.
Consistent with Secs. 63.6(e) and 63.7(e)(1), a deviation that
occurs during a period of startup, shutdown, or malfunction is not a
violation if you demonstrate to the Administrator's satisfaction that
you were operating in accordance with your startup, shutdown, and
malfunction plan. The Administrator will determine whether a deviation
that occurs during a period of startup, shutdown, or malfunction is a
violation according to the provisions in Sec. 63.6(e). As proposed,
multiple deviations from the same control device at the same time when
you monitor process or control device operating parameters are a single
deviation. You still must report each deviation.
You must demonstrate continuous compliance with each emission
limitation and work practice standard that applies to you. To
demonstrate continuous compliance with the emission limitations for
CCU, you must meet each of the conditions specified in Tables 6 and 7
to subpart UUU (for metal HAP emissions) and Tables 13 and 14 to
subpart UUU (for organic HAP emissions). For catalytic reforming units,
you must meet each of the conditions in Tables 20 and 21 to subpart UUU
(for organic HAP emissions) and Tables 27 and 28 to subpart UUU (for
inorganic HAP emissions). For HAP emissions from sulfur recovery units,
you must meet each of the conditions in Tables 34 and 35 to subpart
UUU. Continuous compliance requirements for by-pass lines are in Table
39 to subpart UUU. We have revised the continuous compliance
requirements to reflect the inclusion of new compliance options and
monitoring requirements.

G. What Are the Notification, Recordkeeping, and Reporting
Requirements?

Sections 63.1574 through 63.1576 of the final rule describe the
requirements for notices, reports, and records. As proposed, you may be
required to provide up to seven types of one-time notifications of
applicability, intention to construct or reconstruct (including
construction and startup dates), performance test dates, and compliance
status.
We added a one-time notice for owner and operators to obtain an
extension of compliance on the emission limitations for an existing
CCU. To obtain the extension, the owner or operator must commit to
adding hydrotreatment of the CCU feedstock to meet the final Tier 2
gasoline sulfur control standards (40 CFR part 80, subpart J).
We have streamlined the data requirements for the Notification of
Compliance Status by removing certain information on operation,
maintenance, and monitoring of affected sources and control systems.
This information is to be included in a separate operation,
maintenance, and monitoring plan submitted to your permitting authority
for review and approval. The plan must cover each affected source,
monitoring system or procedure, and control device or method. This plan
also contains information such as the procedures you will use to
monitor certain process or control device operating parameters, your
quality assurance/quality control plan for continuous monitoring
systems, and monitoring and maintenance schedules.
You must submit a semiannual compliance report containing the
information specified in the rule. We revised the rule to require that
you submit the report whether or not a deviation occurred during the
reporting period. However, only summary information is required if no
deviation occurred. As proposed, the rule does not require that you
make emergency reports if actions taken are consistent with your
startup, shutdown, and malfunction plan. If actions taken are not
consistent with your plan, you must report the events and the response
in your semiannual compliance report.
We also revised the proposed rule in response to comments to
include provisions allowing the permitting authority to approve a
period of planned routine maintenance for a refinery with multiple CCU
served by a single wet scrubber emission control device. During this
pre-approved time period, the refinery may take the control device and/
or one of the process units out of service for maintenance while the
remaining process unit(s) continues to operate. To obtain approval, you
must submit a written request at least 6 months before the planned
maintenance is scheduled to begin that contains the specified
information and data. This includes:
A description of the planned routine maintenance and why
it is necessary;
The date the maintenance will begin and end;
A quantified estimate of the emissions (including HAP and
criteria pollutants) that would be released with an analysis of the
environmental benefits (i.e., emission reduction) that would result as
opposed to delaying the maintenance until the next unit turnaround; and
Actions to be taken to minimize emissions during the
period.

[[Page 17768]]

You must include a copy of the request in the compliance report due
for the period before the planned maintenance is scheduled to begin. In
the compliance report due after the routine planned maintenance is
complete, you must provide followup information on the maintenance
including the number of hours the control device did not operate.
As proposed, you must keep records of the information and data
required by Sec. 63.10. This includes information and data you must
record to show continuous compliance with the emission limitations and
work practice standards. You also must keep records of any changes that
affect the performance of your emission control system.

III. Summary of Environmental, Energy, and Economic Impacts

In response to comments, we revised the environmental impacts
analysis in two major respects. First, we incorporated the most current
(1998) facility-specific data available. We removed thermal (non-fluid)
CCU from the analysis because these units are not subject to the final
rule. Finally, we changed the HAP metal emission estimate methodology
to allow more site-specific and unit-specific estimates based on
equilibrium catalyst Ni concentrations. The revised environmental
impacts analysis is available in the docket (Docket A-97-37).

A. What Are the Air Quality Impacts?

We estimate nationwide HAP emissions from process vents on CCU,
catalytic reforming units, and sulfur recovery units at 12,700 tpy at
the current level of control. Most of the 162 existing refineries will
meet the requirements of the rule within 3 years for all affected
sources. A small number of fluid CCU may be granted an extension of
compliance to install hydrotreating unit(s). When this rule is fully
implemented for all affected sources, nationwide HAP emissions will be
reduced by about 11,000 tpy, an 87 percent reduction. Emissions of non-
HAP such as VOC, CO, PM, and hydrogen sulfide will be reduced by about
55 percent from the current level of about 109,000 tpy. Little or no
adverse secondary air impacts, water, or solid waste impacts are
anticipated from the implementation of these standards.

B. What Are the Cost Impacts?

For most facilities, the costs of the rule will be incurred over
the next 3 years. For a few facilities, the costs for fluid CCU will be
incurred over the next 8 years as hydrotreatment units are installed to
meet the requirements of Tier 2 and this rule. The nationwide capital
and annualized costs of control equipment (1998 dollars) are estimated
at $163 million and $37.2 million/yr, respectively. When fully
implemented, this rule is expected to result in an overall annual
national cost of $47.3 million. This includes a cost of $37.2 million
for operation and maintenance of control devices and a monitoring,
recordkeeping, and reporting cost of $10.1 million ($9.2 million for
operation and maintenance of monitoring systems and $0.9 million for
recordkeeping and reporting).
About 75 percent of the facilities are currently meeting at least
one of the emission limits required under the final rule. The costs for
this rule are for the small fraction of refineries not already meeting
the standard. Based on our cost analysis, only 29 of the 124 CCU (23
percent) and 53 of the 185 sulfur recovery units (29 percent) will
require new or upgraded controls. We estimate that 102 of the 177
catalytic reforming units will require new or upgraded control systems
for HCl.

C. What Are the Economic Impacts?

The economic analysis for the proposed rule showed that the
estimated price increase of refined petroleum products is 0.24 percent
for refineries expected to incur compliance costs as a result of the
rule. The estimated decrease in output is 0.17 percent of domestic
refinery products. The decline in domestic production is due to higher
imports and reduced quantity demanded due to higher prices. However,
the value of domestic shipments is expected to increase by 0.07 percent
because the estimated price increase more than offsets the lower
production volume. Annual net exports (exports minus imports) are
predicted to decrease by 0.76 percent. Employment in the industry is
likely to decrease by 0.19 percent (136 jobs). No plant closures or
significant regional impacts are expected. The impacts for the final
rule are expected to be similar to those predicted for the proposed
rule since the overall costs and number of affected facilities changed
only slightly; both overall capital and annual costs and number of
affected sources are estimated to be lower for the final rule.
Therefore, a new economic analysis was not considered necessary and was
not conducted for the final rule. For more information on the economic
impact analysis methodology and results, consult the ``Economic Impact
Analysis for the Petroleum Refinery NESHAP'' (Docket A-97-37).

D. What Are the Non-Air Health and Environmental Impacts?

The control requirements in this rule are based on air pollution
control systems currently in widespread use throughout the petroleum
refining industry. The reduction in emissions of HAP and criteria
pollutants will result in reduced deposition to waterbodies. The
reduction in VOC will reduce ozone formation resulting in less damage
to agricultural crops and forests. A small increase in annual water
usage, about 6.2 million gallons nationwide, will result from the
increased use of wet scrubbers.

E. What Are the Energy Impacts?

The energy impacts also are about the same as the proposed rule.
Once fully implemented, annual electric usage is expected to increase
by about 67,000 megawatt-hours (MW-hrs), primarily for CCU and sulfur
recovery unit control systems. National natural gas usage, primarily
for sulfur recovery unit control systems, is expected to increase by
about 1.5 billion cubic feet per year.

IV. Summary of Major Comments and Responses

A. Why Did We Extend the Compliance Date?

Comment: Several industry commenters urge us to defer or delay
promulgation of the rule to allow time to coordinate with the Tier 2
gasoline sulfur control requirements and other rules such as the
reformulated gasoline (RFG) Phase II standard and the revised national
ambient air quality standard for PM. Their major concern is that plants
will be required to install expensive controls that may be extraneous
as soon as they are installed depending on the outcome of the Tier 2
and other rules.
Response: To comply with the Tier 2 gasoline sulfur control
requirements, individual refineries ultimately will need to produce
gasoline with an average sulfur content of 30 ppm. The majority of
refineries will need to undertake major construction projects to meet
this limit. Since these projects could require modification of CCU and
other affected sources, we revised the schedule to delay promulgation
of this rule until completion of the Tier 2, which was promulgated on
February 10, 2000 (65 FR 6698).
For some refineries, the Tier 2 rule significantly impacts its CCU.
These refineries will have construction projects adding hydrotreating
of the feed to the CCU. For these refineries, we also extended the
compliance date to allow more time for construction projects. We
believe that this will encourage refinery

[[Page 17769]]

owners and operators to employ hydrotreating of the feedstock to comply
with the Tier 2 rule. As discussed in more detail below, we believe
that hydrotreating the feedstock has increased environmental benefits
relative to other methods of reducing gasoline sulfur.
The extended compliance date for existing CCU is based on when and
how a refinery produces low sulfur gasoline to meet the Tier 2 limit.
Hydrotreating the feed to the CCU is one of the means of producing low
sulfur gasoline. As discussed further below, hydrotreating the
feedstock provides environmental benefits not realized with other
methods of producing low sulfur gasoline. It is also, unfortunately,
significantly more expensive than other methods of reducing the sulfur
content of gasoline.
A refinery owner or operator must determine which technology to use
in reducing gasoline sulfur to meet the fuel standards. A number of
alternatives are available. Refineries may elect to hydrotreat after
the CCU, to hydrotreat the CCU feedstock or to implement some other
form of desulfurization technology. Hydrotreating the feedstock removes
metals as well as sulfur. While hydrotreating the feedstock to the unit
would allow greater flexibility within the overall refinery operations
and would better position the refinery for any additional sulfur fuel
standards that might be promulgated in the future, such as standards to
reduce sulfur in diesel fuel (64 FR 26142, May 13, 1999), the cost of
hydrotreating the CCU feed is considerably more than post-unit
hydrotreating for desulfurization. Thus, despite the greater
flexibility realized through hydrotreating the feedstock, there is an
economic bias against its use to reduce gasoline sulfur to meet the
fuel standards. We believe that this bias could increase substantially
if we do not coordinate the compliance dates for these NESHAP and the
Tier 2 rule. A substantial increase in the economic bias against
hydrotreating the feedstock would likely result in less refineries
implementing this method of reducing gasoline sulfur, thereby foregoing
a potentially significant environmental benefit.
Some facilities will take longer than 3 years to comply with the
Tier 2 standards. Should these facilities elect to install
hydrotreatment units for the feed to the CCU, these new units will not
be operating at the compliance date for the MACT standard, 3 years
promulgation. To avoid non-compliance, an owner or operator would be
required to install expensive PM controls to comply with the MACT
standard. These new controls might then become redundant with the later
startup of the hydrotreatment unit for the feed to the CCU. Therefore,
if the owner or operator elects to install a hydrotreatment unit for
the feed to the CCU, the MACT compliance date for the CCU becomes the
same as the Tier 2 compliance date.
Linking the compliance dates for the two rules, in this particular
instance for those refineries that elect to hydrotreat the CCU
feedstock, will allow the refinery to coordinate both decision making
and the actual construction projects and, thus, minimize disruption to
the refinery operations. We believe that not linking the compliance
dates for the two rules could result in an environmental benefit being
foregone and that linking them will result in a net environmental
benefit because the number of process unit shutdowns and startups would
be minimized. Shutdowns and startups can result in considerably more
emissions to the atmosphere than operations under normal conditions. An
estimate of the emissions reductions that would result from linking the
compliance dates for the CCU MACT standards and Tier 2 fuel standards
is not possible at this time. This is because we lack information
regarding how the refineries will choose to comply with the fuel
standards and the uncertainties associated with startup and shutdown of
these refinery operations.
Linking the MACT standards' compliance date to the Tier 2 fuel
standards' compliance date (i.e., the date the refinery produces low
sulfur gasoline at 30 ppm) will not result in an overall or complete
delay of the MACT standards for all CCU. While we believe that linking
the compliance dates will serve as an incentive to hydrotreat the CCU
feedstock, we nevertheless expect that the majority of facilities will
comply with the fuel standards without implementing CCU feedstock
hydrotreating. In some cases, even those that elect to hydrotreat the
feedstock will comply in 3 years or less to take advantage of the
various pooling, averaging, banking, and trading options provided in
the final Tier 2 standards. The remainder of refineries will begin
production of low sulfur gasoline over the next 8-year period, although
most are expected to be in full compliance (i.e., producing gasoline at
the 30 ppm annual average) by the year 2006. In no case will refineries
be allowed any later than December 31, 2009, to comply with the MACT
standard for CCU, which corresponds to the final Tier 2 compliance
date.

B. What Is the New Alternative Nickel Emission Limitation?

Comment: Several industry commenters urge us to include a rate-
based Ni alternative of 0.007 lb Ni/1,000 lbs of coke burn-off in the
final rule. According to the commenters, this approach avoids
penalizing large units with low HAP emissions and equates to the NSPS
for PM by using the highest or worst case Ni equilibrium concentration
to convert PM to Ni. Most of the units that can comply with the PM
limit cannot comply with the mass-based Ni limit due to their greater
size. The commenters argue that larger units should not be subject to a
more restrictive Ni limit than smaller units due to their greater
processing capacity.
Environmental groups and one independent technical expert strongly
disagree that we should provide the second Ni alternative at the level
suggested by industry (i.e., 0.007 lb/1,000 lbs of coke burn-off).
Commenters claim that this alternative is not technically equivalent to
the MACT floor, is not protective of the environment as it is set at a
level that allows all refiners to process heavy feeds with no control
device, will actually increase emissions, and poses difficulties in
ensuring continuous compliance.
Response: After careful review of all the information and data
collected following proposal and received as part of the public
comments, we decided to include an additional metal HAP alternative for
CCU formatted in terms of Ni emissions per 1,000 lbs of coke burn-off.
We concluded that this particular format (i.e., lb Ni/1,000 lbs of coke
burn-off) does account for the wide variation of processing capacity
within the industry and, with the new provisions added to the final
rule, there are adequate means of ensuring continuous compliance.
We also concluded that the technical approach recommended by the
industry commenters (using equilibrium catalyst Ni concentration to
make a direct conversion of the PM emission standard to a Ni limit) is
not appropriate. As discussed further in the Response to Comment
Document, we must reject any method to derive a Ni emission limit in
terms of lb Ni/1,000 lb coke burn-off based on the PM emission limit
and some arbitrarily selected equilibrium catalyst concentration,
whether it is a median, average or highest measured value. The emission
limits calculated using these approaches do not correlate with actual
emissions (in lb Ni/1,000 lbs coke burn-off) of any CCU, and the
resulting Ni emission limits are not

[[Page 17770]]

``equivalent'' to the technology-based standard used as a basis of the
PM emission limit that characterizes performance of the MACT floor
technologies. This is because the equilibrium catalyst Ni concentration
in no way reflects the performance of the MACT floor technology, as PM
emissions. The equilibrium catalyst Ni concentration of a CCU is
dependent on a complex mixture of operating and economic
considerations; it is not totally dictated by the variability of Ni in
the crude oil or the unit feed. In addition, we have no data or
information to relate the equilibrium catalyst metals concentration to
the best performing facilities (i.e., the equilibrium catalyst metal
concentration does not reflect or relate to control device
performance).
Although we do not accept the recommended approach in determining
the emission limit based on an equilibrium catalyst conversion factor,
we feel that the alternative format in terms of lb Ni/1,000 lb of coke
burn-off has considerable merit. This particular format allows for
flexible compliance on the part of the plant owner/operator. An
emission limit expressed in this format can be met by using front-end
hydrotreating, in-process operational changes, or end of pipe add-on
controls alone or in combination.
In addition, to comply with the Tier 2 fuel standards, an owner or
operator must choose one of a number of available methods of reducing
sulfur in gasoline. One of those methods is to hydrotreat CCU
feedstocks. This method of compliance has environmental benefits not
realized with other methods. This is because feedstock hydrotreating
has the potential to reduce Ni emissions from CCU, depending on what
operating changes are made in the catalyst regeneration processes in
conjunction with the feedstock hydrotreating. We believe that a Ni
emission limit, in terms of lb Ni/1,000 lbs coke burn-off, has a
potential to encourage feedstock hydrotreating as a means to comply
with this limit and the Tier 2 fuel standards.
To determine an appropriate emission limit, we examined the
available emissions data for the top performing CCU in terms of lb Ni
emissions/1,000 lb coke burn-off rate. Although the currently available
source test data are somewhat limited and are generally assumed to be
representative of the lowest Ni emitters across the industry, they do
allow an analysis following the basic criteria established for a MACT
floor determination.
Through review of the emission data, we found that the average
emission rates, as well as each individual test run result for the top-
ranked CCU, are all below 0.001 lb Ni/1,000 lbs coke burn-off. Based on
our data analysis, we determined that the emission limit of 0.001 lb
Ni/1,000 lbs coke burn-off adequately characterizes performance of the
MACT floor technology while taking into account process and measurement
variability. This analysis provides an emission limit in the
alternative format (Ni emissions per unit coke burn) that is reflective
of the MACT floor technology. This emission limit is included in the
final rule as an alternative format to the PM or Ni lb/hr limits that
were also selected to characterize the performance of the MACT floor
technologies. The determination of the emission limit formatted in
terms of coke burn-off that is used to characterize the MACT floor
technology is discussed in more detail in the Response to Comments
Document (Docket A-97-36).

C. Why Did We Not Change the Proposed Nickel Emission Limitation?

Comment: Three commenters believe we should relax the proposed Ni
emission limitation (lbs/hr) for metal HAP emissions from CCU. They
question the method we used to determine the numerical emission limit
that characterizes the MACT floor technology in this particular format.
According to the commenters, our variability analysis is flawed for
several reasons.
We used the z-statistic rather than the student's t-
statistic, which is appropriate for small samples from populations.
We used the average relative standard deviation instead of
the more representative maximum relative standard deviation.
The analysis includes data known to be false or
problematic.
We used the 95 percent confidence level rather than the 98
percent interval, which the commenter claims is an EPA precedent.
The commenters also believe the level of emissions that would be
excluded by the higher limit is trivial and of little environmental
significance. Raising the limit would allow some refineries to avoid
installing controls that are not cost effective and provide real de
minimus relief. The commenters support a standard of 760 lbs/yr based
on their approach.
Response: We acknowledge the quality assurance concerns regarding
the results of certain Ni emission measurements and the use of larger
confidence intervals about the average emission value in setting an
emission limit that reflects use of the MACT floor technology. However,
we also believe that the analysis must use the average of the top 12
percent or the 6th percentile facility, rather than the emissions of
the 12th percentile facility. There are 124 fluid CCU in the U.S. and
its territories; the 6th percentile of the industry would be
represented by the emissions reductions achieved by the 7th and 8th
ranked units. Reanalysis of the data, considering the reviewer's
comments on the statistical approach while using the 6th percentile
unit, yields an emission limit nearly identical to the proposed limit.
In response to this comment, we examined the emission rates of the
top performing unit for which we have documented source test results.
We found that the average emission rates, as well as each individual
test run result for the top eight ranked units, are all below 200 lbs/
yr. The 9th and 10th ranked units have similar average emission rates,
but a wider fluctuation in the individual test run results. From the
test data available, we determined that the proposed emission limit of
250 lbs/yr adequately characterizes the performance of the MACT floor
technologies while taking into account process variability. For these
reasons, we made no change in the proposed Ni lb/hr emission limit.

D. How Did We Change the Proposed Monitoring Requirements?

Comment: Environmental groups urge us to require continuous
emission monitoring systems for HCl, TRS, and either CO, TOC, or total
hydrocarbons (THC) for existing and new affected sources. They say
these systems are commercially available, feasible (as stated in the
background information document), ensure standards are met at all
times, and provide better HAP monitoring. They say the cost of these
systems is decreasing, and they may no longer be too costly. Also, the
continuous monitoring of a process allows the operator greater
flexibility in operation which could result in increased output,
improved efficiency, and overall cost savings. Two commenters
specifically request continuous emission monitoring systems for TRS
limits. Due to the TRS emissions from refineries and numerous
exceedances, more accurate information than operating parameter values
is needed to assess compliance.
Response: We agree with the commenters' recommendations that the
NSPS experience with continuous emission monitoring systems
demonstrates their technical and economic feasibility for this
industry,

[[Page 17771]]

provides better data, and needs to be encouraged.
In determining monitoring requirements, we looked at the various
options. One of the options examined was requiring continuous emission
or opacity monitors for all affected sources under this rule. We did
not select this option because of the high capital and operating costs.
However, in response to these comments, we reexamined these options
to look for ways to encourage their use or require their use if needed.
As a result, we included options in the rule allowing plants to choose
to comply with the NSPS monitoring requirements.
We also included requirements in the rule for continuous opacity
monitoring systems for catalyst regenerator vents on any CCU with a
fresh feed capacity greater than 20,000 barrels per day (and not using
wet scrubbers). We also added continuous opacity monitors as a
monitoring option for smaller units. Continuous opacity monitoring
systems are already required for the larger units under Federal/State
implementation plan requirements in 40 CFR part 51, appendix P;
therefore, these costs are not attributable to the standard. We did not
require a continuous opacity monitoring system for a unit with a wet
scrubber because of interference from water vapor in wet scrubber
exhaust gases. For these units, parameter monitoring is still the only
monitoring method.
A continuous emission monitoring system for TRS or reduced sulfur
emissions is also required in the final rule for any sulfur recovery
unit with no add-on control device. The cost of continuous emission
monitoring systems for these units is reasonable and does not pose any
economic hardship for plants that do not use a control device. For
units with add-on control devices, we are confident that the process or
control device parameter monitoring allowed in place of continuous
emission or opacity monitoring systems provides adequate assurance of
continuous compliance.

V. Administrative Requirements

A. Executive Order 12866, Regulatory Planning and Review

Under Executive Order 12866 (58 FR 5173, October 4, 1993), the 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;
(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.
Pursuant to the terms of Executive Order 12866, OMB has notified
EPA that it considers this a ``significant regulatory action'' within
the meaning of the Executive Order. EPA has submitted this action to
OMB for review. Changes made in response to OMB suggestions or
recommendations are documented in the public record.

B. Executive Order 13132, Federalism

Executive Order 13132, entitled ``Federalism'' (64 FR 43255, August
10, 1999), requires EPA to develop an accountable process to ensure
``meaningful and timely input by State and local officials in the
development of regulatory policies that have federalism implications.''
``Policies that have federalism implications'' is defined in the
Executive Order to include regulations that have ``substantial direct
effects on the States, on the relationship between the national
government and the States, or on the distribution of power and
responsibilities among the various levels of government.''
Under section 6 of Executive Order 13132, EPA may not issue a
regulation that has federalism implications, that imposes substantial
direct compliance costs, and that is not required by statute, unless
the Federal government provides the funds necessary to pay the direct
compliance costs incurred by State and local governments, or EPA
consults with State and local officials early in the process of
developing the proposed regulation. The EPA also may not issue a
regulation that has federalism implications and that preempts State
law, unless the EPA consults with State and local officials early in
the process of developing the proposed regulation.
This final rule does not have federalism implications. It will not
have substantial direct effects on the States, on the relationship
between the national government and the States, or on the distribution
of power and responsibilities among the various levels of government,
as specified in Executive Order 13132. None of the affected facilities
are owned or operated by State governments. Thus, the requirements of
section 6 of the Executive Order do not apply to this rule.

C. Executive Order 13175, Consultation and Coordination With Indian
Tribal Governments

Executive Order 13175, entitled ``Consultation and Coordination
with Indian Tribal Governments'' (59 FR 22951, 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.'' ``Policies that have tribal
implications'' is defined in the Executive Order to include regulations
that have ``substantial direct effects on one or more Indian tribes, on
the relationship between the Federal government and the Indian tribes,
or on the distribution of power and responsibilities between the
Federal government and Indian tribes.''
This final rule does not have tribal implications. It will not have
substantial direct effects on tribal governments, on the relationship
between the Federal government and Indian tribes, or on the
distribution of power and responsibilities between the Federal
government and Indian tribes, as specified in Executive Order 13175.
Thus, Executive Order 13175 does not apply to this rule.

D. Executive Order 13045, Protection of Children From Environmental
Health Risks and 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, the 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 the EPA.
This final rule is not subject to Executive Order 13045 because it
is not an economically significant regulatory action as defined by
Executive Order 12866. The EPA interprets Executive Order 13045 as
applying only to

[[Page 17772]]

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. These final NESHAP are not
subject to Executive Order 13045 because they are based on technology
performance and not on health or safety risks.

E. Executive Order 13211, Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution or Use

This rule is not a ``significant energy action'' as defined in
Executive Order 13211, ``Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use'' (66 FR 28355
(May 22, 2001)) because it is not likely to have a significant adverse
effect on the supply, distribution, or use of energy.

F. Unfunded Mandates Reform Act of 1995

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, the
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 by 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 the 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 the 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 the 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.
The EPA has determined that this rule does not contain a Federal
mandate that may result in estimated costs of $100 million or more to
either State, local, or tribal governments, in the aggregate, or to the
private sector in any 1 year. The rule does not significantly or
uniquely impact small governments because it contains no requirements
that apply to such governments or impose obligations upon them. Thus,
the requirements of the UMRA do not apply to this rule.

G. Regulatory Flexibility Act (RFA), As Amended by the Small Business
Regulatory Enforcement Fairness Act of 1996 (SBREFA), 5 U.S.C. 601 et
seq.

The EPA has determined that it is not necessary to prepare a
regulatory flexibility analysis in connection with this final rule. For
the purposes of assessing the impacts of today's rule on small
entities, small entities are defined as: (1) A firm having no more than
1,500 employees and no more than 75,000 barrels per day capacity of
petroleum-based inputs, including crude oil or bona fide feedstocks;\1\
according to Small Business Administration (SBA) size standards
established under the North American Industry Classification System
(NAICS); (2) a small government 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. Small entities in NAICS 32411 only
will be affected.
---------------------------------------------------------------------------

\1\ Capacity includes owned or leased facilities as well as
facilities under a processing agreement or an agreement such as an
exchange agreement or a throughput. The total product to be
delivered under the contract must be at least 90 percent refined by
the successful bidder from either crude oil or bona fide feedstocks.
---------------------------------------------------------------------------

After considering the economic impacts of today's final rule on
small entities, EPA has concluded that this action will not have a
significant economic impact on a substantial number of small entities.
We have determined that nine of the 23 small refiners own one or more
of the affected sources. None of the 9 small refiners will need
additional air pollution control equipment for CCU or sulfur recovery
units. Only those costs for monitoring, reporting, and recordkeeping
would be incurred by these firms. Six small refiners will need to add
control equipment for catalytic reforming units. Annual total
compliance costs for the nine affected small refiners would be less
than 0.01 percent of estimated revenues. For more information, please
consult the public docket for this final rule.
Although this final rule will not have a significant economic
impact on a substantial number of small entities, EPA nonetheless has
tried to reduce the impact of this rule on small entities. As discussed
in the preamble to the proposed rule, EPA met with representatives of
five small refineries and listened to their concerns. In response, we
exercised the maximum degree of flexibility in minimizing impacts on
small business through the alternative Nickel standard and
subcategorization for catalytic reforming units. The rule reflects the
minimum level of control allowed under the CAA. Since proposal, we have
further reduced the economic impact on all refineries, including small
businesses, by subcategorizing CCU and, in appropriate circumstances,
extending the compliance date to coincide with the Tier 2 gasoline
sulfur control rule.

H. Paperwork Reduction Act

The information collection requirements in this final rule are
being submitted for approval to OMB under the requirements of the
Paperwork Reduction Act, 44 U.S.C. 3501 et seq. An information
collection request (ICR) document has been prepared by EPA (ICR No.
1844.01), and a copy may be obtained from Sandy Farmer, Office of
Environmental Information, Collection Strategies Division, U.S.
Environmental Protection Agency (2137), 1200 Pennsylvania Avenue, NW.,
Washington, DC 20460, or by calling (202) 260-2740.
The information collection requirements in the final rule include
mandatory notifications, records, and reports required by the NESHAP
General Provisions (40 CFR part 63, subpart A). These information
requirements are needed to confirm the compliance status of major
sources, to identify any non-major sources not subject to the standard
and any new or reconstructed sources subject to the standards, to
confirm that emission control devices are being properly operated and
maintained, and to ensure that the standards are being achieved. Based
on the recorded and reported information, EPA can decide which
facilities, records, or processes should be inspected. These
recordkeeping and reporting requirements are specifically authorized
under section 114 of the CAA (42 U.S.C. 7414). All information
submitted to EPA for which a claim of

[[Page 17773]]

confidentiality is made will be safeguarded according to EPA policies
in 40 CFR part 2, subpart B.
The annual public reporting and recordkeeping burden for this
collection of information (averaged over the first 3 years after the
effective date of this rule) is estimated to total 19,428 labor hours
per year at a total annual cost of $1.3 million. This estimate includes
initial notifications, a performance test, one-time preparation of a
startup, shutdown, and malfunction plan and operation, maintenance, and
monitoring plan, semiannual deviation summary reports, and
recordkeeping for 132 plants expected to be subject to the rule during
this ICR clearance period. Total capital costs associated with the
monitoring equipment over the 3-year period of the ICR is estimated at
$15.8 million; the annualized cost of capital is estimated at $1.1
million. This estimate includes the capital and startup costs
associated with installation of monitoring equipment.
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 number for EPA's
regulations are listed in 40 CFR part 9 and 48 CFR chapter 15.

I. National Technology Transfer and Advancement Act of 1995

Section 12(d) of the National Technology Transfer and Advancement
Act of 1995 (NTTAA), Public Law 104-113, Sec. 12(d) (15 U.S.C. 272
note) directs EPA to use voluntary consensus in their regulatory and
procurement activities unless to do so would be inconsistent with
applicable law or otherwise impracticable. Voluntary consensus
standards are technical standards (e.g., material specifications, test
methods, sampling procedures, business practices) developed or adopted
by one or more voluntary consensus bodies. The NTTTA requires Federal
agencies to provide Congress, through annual reports to OMB, with
explanations when an agency does not use available and applicable
voluntary consensus standards.
Consistent with the NTTAA, we conducted searches to identify
voluntary consensus standards for use in emissions testing. The search
for emissions testing procedures identified 34 voluntary consensus
standards that appeared to have possible use in lieu of EPA standard
reference methods. After reviewing the available standards, we
determined that 26 of the candidate consensus standards identified for
measuring emissions of the HAP or surrogates subject to the emission
limitations in the rule would not be practical due to lack of
equivalency, documentation, validation data, and other important
technical and policy considerations. Eight of the remaining candidate
consensus are under development or currently under EPA review. We plan
to follow, review, and consider adopting these standards after their
development and we complete further review.
One consensus standard, ASTM D6216-98, is practical for EPA use in
Performance Specification 1 (PS-1) in 40 CFR part 60, appendix B,
``Specifications and Test Procedures for Opacity Continuous Emission
Monitoring Systems in Stationary Sources.'' This ASTM method can best
be used in place of the design specification verification procedures
currently in sections 5 and 6 of PS-1. We proposed ASTM D6216-98 for
incorporation by reference in another rulemaking (63 FR 50824,
September 23, 1998). Comments from the proposal have been addressed and
we expect to complete this action in the near future. For these
reasons, we do not propose to adopt ASTM D6216-98 in lieu of PS-1
requirements as it would be impractical to us to act independently from
the other rulemaking already undergoing promulgation, and because ASTM
D6216 does not address all the requirements specified in PS-1.
Tables 4 and 40 in subpart UUU list the EPA test methods and
performance specifications included in this rule. Most of these methods
and performance specifications have been used by States and industry
for more than 10 years. Nevertheless, as provided by Sec. 63.7(f) of
the NESHAP General Provisions (40 CFR part 63, subpart A), any State or
facility may apply to EPA for permission to use an alternative method
in place of any of the EPA test methods or performance specifications
listed in the rule.

J. Congressional Review Act

The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the
Small Business Regulatory Enforcement Fairness Act of 1996, generally
provides that before a rule may take effect, the agency promulgating
the rule must submit a rule report, which includes a copy of the rule,
to each House of the Congress and to the Comptroller General of the
United States. The EPA will submit a report containing this rule and
other required information to the U.S. Senate, the U.S. House of
Representatives, and the Comptroller General of the United States prior
to publication of the rule in the Federal Register. This rule is not a
``major rule'' as defined by 5 U.S.C. 804(2).

What This Subpart Covers

Sec. 63.1560 What is the purpose of this subpart?

This subpart establishes national emission standards for hazardous
air pollutants (HAP) emitted from petroleum refineries. This subpart
also establishes requirements to demonstrate initial and continuous
compliance with the emission limitations and work practice standards.

Sec. 63.1561 Am I subject to this subpart?

(a) You are subject to this subpart if you own or operate a
petroleum refinery that is located at a major source of HAP emissions.
(1) A petroleum refinery is an establishment engaged primarily in
petroleum refining as defined in the Standard Industrial Classification
(SIC) code 2911 and the North American Industry Classification (NAIC)
code 32411, and used mainly for:
(i) Producing transportation fuels (such as gasoline, diesel fuels,
and jet fuels), heating fuels (such as kerosene, fuel gas distillate,
and fuel oils), or lubricants;
(ii) Separating petroleum; or
(iii) Separating, cracking, reacting, or reforming an intermediate
petroleum

[[Page 17775]]

stream, or recovering a by-product(s) from the intermediate petroleum
stream (e.g., sulfur recovery).
(2) A major source of HAP is a plant site that emits or has the
potential to emit any single HAP at a rate of 9.07 megagrams (10 tons)
or more per year or any combination of HAP at a rate of 22.68 megagrams
(25 tons) or more per year.
(b) [Reserved]

Sec. 63.1562 What parts of my plant are covered by this subpart?

(a) This subpart applies to each new, reconstructed, or existing
affected source at a petroleum refinery.
(b) The affected sources are:
(1) Each catalytic cracking unit that regenerates catalyst.
(2) Each catalytic reforming unit that regenerates catalyst.
(3) Each sulfur recovery unit and the tail gas treatment unit
serving it.
(4) Each bypass line serving a new, existing, or reconstructed
catalytic cracking unit, catalytic reforming unit, or sulfur recovery
unit. This means each vent system that contains a bypass line (e.g.,
ductwork) that could divert an affected vent stream away from a control
device used to comply with the requirements of this subpart.
(c) An affected source is a new affected source if you commence
construction of the affected source after September 11, 1998, and you
meet the applicability criteria in Sec. 63.1561 at the time you
commenced construction.
(d) Any affected source is reconstructed if you meet the criteria
in Sec. 63.2.
(e) An affected source is existing if it is not new or
reconstructed.
(f) This subpart does not apply to:
(1) A thermal catalytic cracking unit.
(2) A sulfur recovery unit that does not recover elemental sulfur
or where the modified reaction is carried out in a water solution which
contains a metal ion capable of oxidizing the sulfide ion to sulfur
(e.g., the LO-CAT II process).
(3) A redundant sulfur recovery unit not located at a petroleum
refinery and used by the refinery only for emergency or maintenance
backup.
(4) Equipment associated with bypass lines such as low leg drains,
high point bleed, analyzer vents, open-ended valves or lines, or
pressure relief valves needed for safety reasons.
(5) Gaseous streams routed to a fuel gas system.

Sec. 63.1563 When do I have to comply with this subpart?

(a) If you have a new or reconstructed affected source, you must
comply with this subpart according to the requirements in paragraphs
(a)(1) and (2) of this section.
(1) If you startup your affected source before April 11, 2002, then
you must comply with the emission limitations and work practice
standards for new and reconstructed sources in this subpart no later
than April 11, 2002.
(2) If you startup your affected source after April 11, 2002, you
must comply with the emission limitations and work practice standards
for new and reconstructed sources in this subpart upon startup of your
affected source.
(b) If you have an existing affected source, you must comply with
the emission limitations and work practice standards for existing
affected sources in this subpart by no later than April 11, 2005 except
as specified in paragraph (c) of this section.
(c) We will grant an extension of compliance for an existing
catalytic cracking unit allowing additional time to meet the emission
limitations and work practice standards for catalytic cracking units in
Secs. 63.1564 and 63.1565 if you commit to hydrotreating the catalytic
cracking unit feedstock and to meeting the emission limitations of this
subpart on the same date that your facility meets the final Tier 2
gasoline sulfur control standard (40 CFR part 80, subpart J). To obtain
an extension, you must submit a written notification to your permitting
authority according to the requirements in Sec. 63.1574(e). Your
notification must include the information in paragraphs (c)(1) and (2)
of this section.
(1) Identification of the affected source with a brief description
of the controls to be installed (if needed) to comply with the emission
limitations for catalytic cracking units in this subpart.
(2) A compliance schedule, including the information in paragraphs
(c)(2)(i) through (iv) of this section.
(i) The date by which onsite construction or the process change is
to be initiated.
(ii) The date by which onsite construction or the process change is
to be completed.
(iii) The date by which your facility will achieve final compliance
with both the final Tier 2 gasoline sulfur control standard as
specified in Sec. 80.195, and the emission limitations and work
practice standards for catalytic cracking units in this subpart. In no
case will your permitting authority grant an extension beyond the date
you are required to meet the Tier 2 gasoline sulfur control standard or
December 31, 2009, whichever comes first. If you don't comply with the
emission limitations and work practice standards for existing catalytic
cracking units by the specified date, you will be out-of-compliance
with the requirements for catalytic cracking units beginning April 11,
2005.
(iv) A brief description of interim emission control measures that
will be taken to ensure proper operation and maintenance of the process
equipment during the period of the compliance extension.
(d) If you have an area source that increases its emissions or its
potential to emit such that it becomes a major source of HAP, the
requirements in paragraphs (d)(1) and (2) of this section apply.
(1) Any portion of the existing facility that is a new affected
source or a new reconstructed source must be in compliance with the
requirements of this subpart upon startup.
(2) All other parts of the source must be in compliance with the
requirements of this subpart by no later than 3 years after it becomes
a major source or, if applicable, the extended compliance date granted
according to the requirements in paragraph (c) of this section.
(e) You must meet the notification requirements in Sec. 63.1574
according to the schedule in Sec. 63.1574 and in 40 CFR part 63,
subpart A. Some of the notifications must be submitted before the date
you are required to comply with the emission limitations and work
practice standards in this subpart.

Catalytic Cracking Units, Catalytic Reforming Units, Sulfur
Recovery Units, and Bypass Lines

Sec. 63.1564 What are my requirements for metal HAP emissions from
catalytic cracking units?

(a) What emission limitations and work practice standards must I
meet? You must:
(1) Meet each emission limitation in Table 1 of this subpart that
applies to you. If your catalytic cracking unit is subject to the NSPS
for PM in Sec. 60.102 of this chapter, you must meet the emission
limitations for NSPS units. If your catalytic cracking unit isn't
subject to the NSPS for PM, you can choose from the four options in
paragraphs (a)(1)(i) through (iv) of this section:

(g) Consistent with Secs. 63.6(e) and 63.7(e)(1), deviations that
occur during a period of startup, shutdown, or malfunction are not
violations if you demonstrate to the Administrator's satisfaction that
you were operating in accordance with the SSMP. The SSMP must require
that good air pollution control practices are used during those
periods. The plan must also include elements designed to minimize the
frequency of such periods (i.e., root cause analysis). The
Administrator will determine whether deviations that occur during a
period of startup, shutdown, or malfunction are violations, according
to the provisions in Sec. 63.6(e) and the contents of the SSMP.

Sec. 63.1571 How and when do I conduct a performance test or other
initial compliance demonstration?

(a) When must I conduct a performance test? You must conduct
performance tests and report the results by no later than 150 days
after the compliance date specified for your source in Sec. 63.1563 and
according to the provisions in Sec. 63.7(a)(2). If you are required to
do a performance evaluation or test for a semi-regenerative catalytic
reforming unit catalyst regenerator vent, you may do them at the first
regeneration cycle after your compliance date and report the results in
a followup Notification of Compliance Status report due no later than
150 days after the test.
(1) For each emission limitation or work practice standard where
initial compliance is not demonstrated using a performance test,
opacity observation, or visible emission observation, you must conduct
the initial compliance demonstration within 30 calendar days after the
compliance date that is specified for your source in Sec. 63.1563.
(2) For each emission limitation where the averaging period is 30
days, the 30-day period for demonstrating initial compliance begins at
12:00 a.m. on the compliance date that is specified for your source in
Sec. 63.1563 and ends at 11:59 p.m., 30 calendar days after the
compliance date that is specified for your source in Sec. 63.1563.
(3) If you commenced construction or reconstruction between
September 11, 1998 and April 11, 2002, you must demonstrate initial
compliance with either the proposed emission limitation or the
promulgated emission limitation no later than October 8, 2002 or within
180 calendar days after startup of the source, whichever is later,
according to Sec. 63.7(a)(2)(ix).
(4) If you commenced construction or reconstruction between
September 11, 1998 and April 11, 2002, and you chose to comply with the
proposed emission limitation when demonstrating initial compliance, you
must conduct a second compliance demonstration for the promulgated
emission limitation by October 10, 2005, or after startup of the
source, whichever is later, according to Sec. 63.7(a)(2)(ix).
(b) What are the general requirements for performance test and
performance evaluations? You must:
(1) Conduct each performance test according to the requirements in
Sec. 63.7(e)(1).
(2) Except for opacity and visible emission observations, conduct
three separate test runs for each performance test as specified in
Sec. 63.7(e)(3). Each test run must last at least 1 hour.
(3) Conduct each performance evaluation according to the
requirements in Sec. 63.8(e).
(4) Not conduct performance tests during periods of startup,
shutdown, or malfunction, as specified in Sec. 63.7(e)(1).
(5) Calculate the average emission rate for the performance test by
calculating the emission rate for each individual test run in the units
of the applicable emission limitation using Equation 2, 5, or 8 of
Sec. 63.1564, and determining the arithmetic average of the calculated
emission rates.
(c) What procedures must I use for an engineering assessment? You
may choose to use an engineering assessment to calculate the process
vent flow rate, net heating value, TOC emission rate, and total organic
HAP emission rate expected to yield the highest daily emission rate
when determining the emission reduction or outlet concentration for the
organic HAP standard for catalytic reforming units. If you use an
engineering assessment, you must document all data, assumptions, and
procedures to the satisfaction of the applicable permitting authority.
An engineering assessment may include the approaches listed in
paragraphs (c)(1) through (c)(4) of this section. Other engineering
assessments may be used but are subject to review and approval by the
applicable permitting authority.
(1) You may use previous test results provided the tests are
representative of current operating practices at the process unit, and
provided EPA

[[Page 17782]]

methods or approved alternatives were used;
(2) You may use bench-scale or pilot-scale test data representative
of the process under representative operating conditions;
(3) You may use maximum flow rate, TOC emission rate, organic HAP
emission rate, or organic HAP or TOC concentration specified or implied
within a permit limit applicable to the process vent; or
(4) You may use design analysis based on engineering principles,
measurable process parameters, or physical or chemical laws or
properties. Examples of analytical methods include, but are not limited
to:
(i) Use of material balances based on process stoichiometry to
estimate maximum TOC concentrations;
(ii) Calculation of hourly average maximum flow rate based on
physical equipment design such as pump or blower capacities; and
(iii) Calculation of TOC concentrations based on saturation
conditions.
(d) Can I adjust the process or control device measured values when
establishing an operating limit? If you do a performance test to
demonstrate compliance, you must base the process or control device
operating limits for continuous parameter monitoring systems on the
results measured during the performance test. You may adjust the values
measured during the performance test according to the criteria in
paragraphs (d)(1) through (3) of this section.
(1) If you must meet the HAP metal emission limitations in
Sec. 63.1564, you elect the option in paragraph (a)(1)(iii) in
Sec. 63.1564 (Ni lb/hr), and you use continuous parameter monitoring
systems, you must establish an operating limit for the equilibrium
catalyst Ni concentration based on the laboratory analysis of the
equilibrium catalyst Ni concentration from the initial performance
test. Section 63.1564(b)(2) allows you to adjust the laboratory
measurements of the equilibrium catalyst Ni concentration to the
maximum level. You must make this adjustment using Equation 1 of this
section as follows:
[GRAPHIC]
[TIFF OMITTED]
TR11AP02.017

Where:

Ecat-Limit = Operating limit for equilibrium catalyst Ni concentration,
mg/kg;
NiEmR1_st = Average Ni emission rate calculated as the
arithmetic average Ni emission rate using Equation 5 of this section
for each performance test run, g Ni/hr; and
Ecat_st = Average equilibrium Ni concentration from
laboratory test results, mg/kg.

(2) If you must meet the HAP metal emission limitations in
Sec. 63.1564, you elect the option in paragraph (a)(1)(iv) in
Sec. 63.1564 (Ni lb/1,000 lb of coke burn-off), and you use continuous
parameter monitoring systems, you must establish an operating limit for
the equilibrium catalyst Ni concentration based on the laboratory
analysis of the equilibrium catalyst Ni concentration from the initial
performance test. Section 63.1564(b)(2) allows you to adjust the
laboratory measurements of the equilibrium catalyst Ni concentration to
the maximum level. You must make this adjustment using Equation 2 of
this section as follows:
[GRAPHIC]
[TIFF OMITTED]
TR11AP02.018

Where:

NiEmR2_st = Average Ni emission rate calculated as the
arithmetic average Ni emission rate using Equation 8 of Sec. 63.1564
for each performance test run, mg/kg coke burn-off.

(3) If you choose to adjust the equilibrium catalyst Ni
concentration to the maximum level, you can't adjust any other
monitored operating parameter (i.e., gas flow rate, voltage, pressure
drop, liquid-to-gas ratio).
(4) Except as specified in paragraph (d)(3) of this section, if you
use continuous parameter monitoring systems, you may adjust one of your
monitored operating parameters (flow rate, voltage and secondary
current, pressure drop, liquid-to-gas ratio) from the average of
measured values during the performance test to the maximum value (or
minimum value, if applicable) representative of worst-case operating
conditions, if necessary. This adjustment of measured values may be
done using control device design specifications, manufacturer
recommendations, or other applicable information. You must provide
supporting documentation and rationale in your Notification of
Compliance Status, demonstrating to the satisfaction of your permitting
authority, that your affected source complies with the applicable
emission limit at the operating limit based on adjusted values.
(e) Can I change my operating limit? You may change the established
operating limit by meeting the requirements in paragraphs (e)(1)
through (3) of this section.
(1) You may change your established operating limit for a
continuous parameter monitoring system by doing an additional
performance test, a performance test in conjunction with an engineering
assessment, or an engineering assessment to verify that, at the new
operating limit, you are in compliance with the applicable emission
limitation.
(2) You must establish a revised operating limit for your
continuous parameter monitoring system if you make any change in
process or operating conditions that could affect control system
performance or you change designated conditions after the last
performance or compliance tests were done. You can establish the
revised operating limit as described in paragraph (e)(1) of this
section.
(3) You may change your site-specific opacity operating limit or Ni
operating limit only by doing a new performance test.

Sec. 63.1572 What are my monitoring installation, operation, and
maintenance requirements?

(a) You must install, operate, and maintain each continuous
emission monitoring system according to the requirements in paragraphs

that has already demonstrated initial compliance with the applicable
performance specification.
(3) As specified in Sec. 63.8(c)(4)(ii), each continuous emission
monitoring system must complete a minimum of one cycle of operation
(sampling, analyzing, and data recording) for each successive 15-minute

this subpart.
(2) If you use a continuous opacity monitoring system to meet the
NSPS opacity limit, you must conduct a performance evaluation of each
continuous opacity monitoring system according to the requirements in
Sec. 63.8 and Table 40 of this subpart. This requirement does not apply
to an affected source subject to the NSPS that has already demonstrated

minimum of one cycle of operation for each successive 15-minute period.
You must have a minimum of four successive cycles of operation to have
a valid hour of data (or at least two if a calibration check is
performed during that hour or if the continuous parameter monitoring
system is out-of-control).
(3) Each continuous parameter monitoring system must have valid
hourly average data from at least 75 percent of the hours during which
the process operated.
(4) Each continuous parameter monitoring system must determine and
record the hourly average of all recorded readings and if applicable,
the daily average of all recorded readings for each operating day. The
daily average must cover a 24-hour period if operation is continuous or
the number of hours of operation per day if operation is not
continuous.
(5) Each continuous parameter monitoring system must record the
results of each inspection, calibration, and validation check.

required quality assurance or control activities (including as
applicable, calibration checks and required zero and span adjustments),
you must conduct all monitoring in continuous operation (or collect
data at all required intervals) at all times the affected source is
operating.
(2) You may not use data recorded during monitoring malfunctions,
associated repairs, and required quality assurance or control
activities for purposes of this regulation, including data averages and
calculations, for fulfilling a minimum data availability requirement,
if applicable. You must use all the data collected during all other
periods in assessing the operation of the control device and associated
control system.

Sec. 63.1573 What are my monitoring alternatives?

(a) What is the approved alternative for monitoring gas flow rate?
You can elect to use this alternative to a continuous parameter
monitoring system for the catalytic regenerator exhaust gas flow rate
for your catalytic cracking unit if the unit does not introduce any
other gas streams into the catalyst regeneration vent (i.e., complete
combustion units with no additional combustion devices). If you select
this alternative, you must use the same procedure for the performance
test and for monitoring after the performance test.
(1) Install and operate a continuous parameter monitoring system to
measure and record the hourly average volumetric air flow rate to the
catalytic cracking unit regenerator. Or, you can determine and record
the hourly average volumetric air flow rate to the catalytic cracking
unit regenerator using the catalytic cracking unit control room
instrumentation.
(2) Install and operate a continuous parameter monitoring system to
measure and record the temperature of the gases entering the control
device (or exiting the catalyst regenerator if you do not use an add-on
control device).
(3) Calculate and record the hourly average actual exhaust gas flow
rate using Equation 1 of this section as follows:
[GRAPHIC]
[TIFF OMITTED]
TR11AP02.019

Where:

Q_gas = Hourly average actual gas flow rate, acfm;
1.12 = Default correction factor to convert gas flow from dry standard
cubic feet per minute (dscfm) to standard cubic feet per minute (scfm);
Q_air = Volumetric flow rate of air to regenerator, as
determined from the catalytic cracking unit control room
instrumentations, dscfm;
Q_oxy = Volumetric flow rate of oxygen-enriched air stream to
regenerator, as determined from the catalytic cracking unit control
room instrumentations, dscfm;
Temp_gas = Temperature of gas stream in vent measured as near
as practical to the control device or opacity monitor, deg.K. For wet
scrubbers, temperature of gas prior to the wet scrubber; and

[[Page 17784]]

P_vent = Absolute pressure in the vent measured as near as
practical to the control device or opacity monitor, atm. When used in
conjunction with opacity in the final vent stack, you can assume
P_vent = 1 atm.

(b) What is the approved alternative for monitoring pH levels? If
you use a wet scrubber to control inorganic HAP emissions from your
vent on a catalytic reforming unit, you can measure and record the pH
of the water (or scrubbing liquid) exiting the scrubber at least once
an hour during coke burn-off and catalyst rejuvenation using pH strips
as an alternative to a continuous parameter monitoring system. The pH
strips must meet the requirements in Table 41 of this subpart.
(c) Can I use another type of monitoring system? You may request
approval from your permitting authority to use an automated data
compression system. An automated data compression system does not
record monitored operating parameter values at a set frequency (e.g.,
once every hour) but records all values that meet set criteria for
variation from previously recorded values. Your request must contain a
description of the monitoring system and data recording system,
including the criteria used to determine which monitored values are
recorded and retained, the method for calculating daily averages, and a
demonstration that the system meets all of the criteria in paragraphs
(c)(1) through (5) of this section:
(1) The system measures the operating parameter value at least once
every hour;
(2) The system records at least 24 values each day during periods
of operation;
(3) The system records the date and time when monitors are turned
off or on;
(4) The system recognizes unchanging data that may indicate the
monitor is not functioning properly, alerts the operator, and records
the incident; and
(5) The system computes daily average values of the monitored
operating parameter based on recorded data.
(d) Can I monitor other process or control device operating
parameters? You may request approval to monitor parameters other than
those required in this subpart. You must request approval if:
(1) You use a control device other than a thermal incinerator,
boiler, process heater, flare, electrostatic precipitator, or wet
scrubber;
(2) You use a combustion control device (e.g., incinerator, flare,
boiler or process heater with a design heat capacity of at least 44 MW,
boiler or process heater where the vent stream is introduced into the
flame zone), electrostatic precipitator, or scrubber but want to
monitor a parameter other than those specified; or
(3) You wish to use another type of continuous emission monitoring
system that provides direct measurement of a pollutant (i.e., a PM or
multi-metals HAP continuous emission monitoring system, a carbonyl
sulfide/carbon disulfide continuous emission monitoring system, a TOC
continuous emission monitoring system, or HCl continuous emission
monitoring system).
(e) How do I request to monitor alternative parameters? You must
submit a request for review and approval or disapproval to the
Administrator. The request must include the information in paragraphs
(e)(1) through (5) of this section.
(1) A description of each affected source and the parameter(s) to
be monitored to determine whether the affected source will continuously
comply with the emission limitations and an explanation of the criteria
used to select the parameter(s).
(2) A description of the methods and procedures that will be used
to demonstrate that the parameter can be used to determine whether the
affected source will continuously comply with the emission limitations
and the schedule for this demonstration. You must certify that you will
establish an operating limit for the monitored parameter(s) that
represents the conditions in existence when the control device is being
properly operated and maintained to meet the emission limitation.
(3) The frequency and content of monitoring, recording, and
reporting, if monitoring and recording are not continuous. You also
must include the rationale for the proposed monitoring, recording, and
reporting requirements.
(4) Supporting calculations.
(5) Averaging time for the alternative operating parameter.

for pressure (if applicable to the sampling equipment).
(vii) Procedures you will use to determine the gas flow rate for a
catalytic cracking unit if you use the alternative procedure based on
air flow rate and temperature.
(viii) Monitoring schedule, including when you will monitor and

must continuously monitor and record the air flow rate to the regenerator and the temperature of the gases
entering the control device as described in Sec. 63.1573. You must determine and record the hourly average
gas flow rate using Equation 1 of Sec. 63.1573 and the daily average gas flow rate. You must maintain the
daily average gas flow rate below the operating limit established during the performance test.
