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'' (65 FR 67249, November 6, 2000), 
requires EPA to develop an accountable process to ensure ``meaningful 
and timely input by tribal officials in the development of regulatory 
policies that have tribal implications.'' ``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.

    (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.

(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.

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,

General Compliance Requirements


Sec. 63.1570  What are my general requirements for complying with this 
subpart?

    (a) You must be in compliance with all of the non-opacity standards 
in this subpart during the times specified in Sec. 63.6(f)(1).
    (b) You must be in compliance with the opacity and visible emission 
limits in this subpart during the times specified in Sec. 63.6(h)(1).
    (c) You must always operate and maintain your affected source, 
including air pollution control and monitoring equipment, according to 
the provisions in Sec. 63.6(e)(1)(i). During the period between the 
compliance date specified for your affected source and the date upon 
which continuous monitoring systems have been installed and validated 
and any applicable operating limits have been set, you must maintain a 
log detailing the operation and maintenance of the process and 
emissions control equipment.
    (d) You must develop and implement a written startup, shutdown, and 
malfunction plan (SSMP) according to the provisions in Sec. 63.6(e)(3).
    (e) During periods of startup, shutdown, and malfunction, you must 
operate in accordance with your SSMP.
    (f) You must report each instance in which you did not meet each 
emission limitation and each operating limit in this subpart that 
applies to you. This includes periods of startup, shutdown, and 
malfunction. You also must report each instance in which you did not 
meet the work practice standards in this subpart that apply to you. 
These instances are deviations from the emission limitations and work 
practice standards in this subpart. These deviations must be reported 
according to the requirements in Sec. 63.1575.
    (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;
NiEmR1st = 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
Ecatst = 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:

NiEmR2st = 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.

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

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:

Qgas = 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);
Qair = Volumetric flow rate of air to regenerator, as 
determined from the catalytic cracking unit control room 
instrumentations, dscfm;
Qoxy = Volumetric flow rate of oxygen-enriched air stream to 
regenerator, as determined from the catalytic cracking unit control 
room instrumentations, dscfm;
Tempgas = 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]]

Pvent = 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 
Pvent = 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;

    (3) If you are required to conduct a performance test, performance 
evaluation, design evaluation, opacity observation, visible emission 
observation, or other initial compliance demonstration, you must submit 
a notification of compliance status according to Sec. 63.9(h)(2)(ii). 
You can submit this information in an operating permit application, in 
an amendment to an operating permit application, in a separate 
submission, or in any combination. In a State with an approved 
operating permit program where delegation of authority under section 
112(l) of the CAA has not been requested or approved, you must provide 
a duplicate notification to the applicable Regional Administrator. If 
the required information has been submitted previously, you do not have 
to provide a separate notification of compliance status. Just refer to 
the earlier submissions instead of duplicating and resubmitting the 
previously submitted information.
    (i) For each initial compliance demonstration that does not include 
a performance test, you must submit the Notification of Compliance 
Status no later than 30 calendar days following completion of the 
initial compliance demonstration.

device operating parameters for each affected source.
    (iii) Procedures that you will use to determine the coke burn-rate, 
the volumetric flow rate (if you use process data rather than direct 
measurement), and the rate of combustion of liquid or solid fossil 
fuels if you use an incinerator-waste heat boiler to burn the exhaust 
gases from a catalyst regenerator.
    (iv) Procedures and analytical methods you will use to determine 
the equilibrium catalyst Ni concentration, the equilibrium catalyst Ni 
concentration monthly rolling average, and the hourly or hourly average 
Ni operating value.
    (v) Procedures you will use to determine the pH of the water (or 
scrubbing liquid) exiting a wet scrubber if you use pH strips.
    (vi) Procedures you will use to determine the HCl concentration of 
gases from a semi-regenerative catalytic reforming unit with an 
internal scrubbing system (i.e., no add-on control device) when you use 
a colormetric tube sampling system, including procedures for correcting 
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 
when you will not monitor an affected source (e.g., during the coke 
burn-off, regeneration process).
    (ix) Quality control plan for each continuous opacity monitoring 
system and continuous emission monitoring system you use to meet an 
emission limit in this subpart. This plan must include procedures you 
will use for calibrations, accuracy audits, and adjustments to the 
system needed to meet applicable requirements for the system.

destroying organic compounds, with or without heat recovery. Auxiliary 
fuel may be used to heat waste gas to combustion temperatures. An 
incinerator may use a catalytic combustion process where a substance is 
introduced into an exhaust stream to burn or oxidize contaminants while 
the substances itself remains intact, or a thermal process which uses 
elevated temperatures as a primary means to burn or oxidize 
contaminants.

emissions of particulate matter and metal HAP contained in the 
particulate matter, including but not limited to: antimony, arsenic, 
beryllium, cadmium, chromium, cobalt, lead, manganese, nickel, and 
selenium as measured by Methods 5B or 5F in appendix A to part 60 of 
this chapter or by an approved alternative method.
    Process heater means an enclosed combustion device that primarily 
transfers heat liberated by burning fuel directly to process streams or 
to heat transfer liquids other than water.
    Process vent means, for the purposes of this subpart, a gas stream 
that is continuously or periodically discharged during normal operation 
of a catalytic cracking unit, catalytic reforming unit, or sulfur 
recovery unit, including gas streams that are discharged directly to 
the atmosphere, gas streams that are routed to a control device prior 
to discharge to the atmosphere, or gas streams that are diverted 
through a product recovery device line prior to control or discharge to 
the atmosphere.
    Reduced sulfur compounds means hydrogen sulfide, carbonyl sulfide, 
and carbon disulfide.

the owner's or operator's convenience for in situ catalyst 
regeneration.
    Sulfur recovery unit means a process unit that recovers elemental 
sulfur from gases that contain reduced sulfur compounds and other 
pollutants, usually by a vapor-phase catalytic reaction of sulfur 
dioxide and hydrogen sulfide. This definition does not include a unit 
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.
    TOC means, for the purposes of this subpart, emissions of total 
organic compounds, excluding methane and ethane, that serve as a 
surrogate measure of the total emissions of organic HAP compounds, 
including but not limited to, acetaldehyde, benzene, hexane, phenol, 
toluene, and xylenes and non-HAP VOC as measured by Method 25 or 25A in 
appendix A to part 60 of this chapter or an approved alternative 
method.
    TRS means, for the purposes of this subpart, emissions of total 
reduced sulfur compounds, expressed as an equivalent sulfur dioxide 
concentration, that serve as a surrogate measure of the total emissions 
of sulfide HAP carbonyl sulfide and carbon disulfide as measured by 
Method 15 in appendix A to part 60 of this chapter or by an approved 
alternative method.
    Work practice standard means any design, equipment, work practice, 
or operational standard, or combination thereof, that is promulgated

\1\ If applicable, you can use the alternative in Sec.  63.1573 for gas flow rate instead of a continuous
  parameter monitoring system if you used the alternative method in the initial performance test. If so, you
  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.
