National Emission Standards for Hazardous Air Pollutant 
Emissions: Petroleum Refinery Sector Amendments

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: This action proposes amendments to the National Emission 
Standards for Hazardous Air Pollutants (NESHAP) Refinery MACT 1 and 
Refinery MACT 2 regulations and the New Source Performance Standards 
(NSPS) for petroleum refineries, which were published on December 1, 
2015. In that action, as a result of a risk and technology review, the 
Environmental Protection Agency (EPA) finalized amendments to Refinery 
MACT 1 and Refinery MACT 2. In this action, the EPA is proposing to 
amend the compliance date in Refinery MACT 1 for maintenance vent 
standards that apply during periods of startup, shutdown, maintenance 
or inspection for sources constructed or reconstructed on or before 
June 30, 2014. In this action, the EPA is also proposing to revise the 
compliance dates in Refinery MACT 2 for the standards that apply during 
startup, shutdown, or hot standby for fluid catalytic cracking units 
(FCCU) and startup and shutdown for sulfur recovery units (SRU) 
constructed or reconstructed on or before June 30, 2014. These proposed 
revisions do not affect requirements that apply during normal 
operations. Finally, the EPA is proposing technical corrections and 
clarifications to the NESHAP and the NSPS for petroleum refineries. 
This action will have an insignificant effect on emissions reductions 
and costs.

II. Background Information

    On December 1, 2015 (80 FR 75178), the EPA finalized amendments to 
the Petroleum Refinery NESHAP in 40 CFR part 63, subparts CC and UUU, 
referred to as Refinery MACT 1 and 2, respectively. The final 
amendments to Refinery MACT 1 and 2 include a number of provisions 
establishing emissions limitations during startup and shutdown for 
emissions sources at petroleum refineries, including specific 
provisions for maintenance vents, FCCU, and SRU, which are the focus of 
this proposed action.
    The Refinery MACT 1 standards regulate emissions of hazardous air 
pollutants (HAP) from miscellaneous process vents. Prior to the 
December 2015 amendments, the definition of miscellaneous process vents 
excluded episodic or non-routine releases such as those associated with 
startup, shutdown, and maintenance. The December 2015 Refinery MACT 1 
rule eliminates this exclusion from the definition of miscellaneous 
process vent and establishes standards for these ``maintenance vents'' 
in 40 CFR 63.643(c). Maintenance vents are only used as a result of 
startup, shutdown, maintenance or inspection of equipment when such 
equipment is emptied, depressurized, degassed, or placed into service. 
The rule specifies that refinery owners or operators may only release 
HAP from these maintenance vents in order to open process equipment 
provided that the equipment is drained and purged to a closed system 
until the hydrocarbon content is less than or equal to a lower 
explosive limit (LEL) of 10 percent prior to venting to the atmosphere. 
As a secondary limit, if the LEL cannot be measured due to design 
constraints of the equipment, the rule requires that the pressure in 
the equipment be reduced to 5 pounds (lbs) per square inch gauge or 
less prior to venting to the atmosphere. The rule also contains 
additional limits such as a low emission threshold (less than 72 lbs/
day), and requirements for catalyst changeout activities where 
hydrotreater pyrophoric catalyst must be purged.
    The Refinery MACT 2 standards regulate HAP emissions from the FCCU 
by specifying carbon monoxide (CO) limits as a surrogate for organic 
HAP and by specifying particulate matter (PM) limits (or nickel limits) 
as a surrogate for metal HAP. In the rule, compliance with the organic 
HAP emissions limit is demonstrated using a continuous CO monitor; 
compliance with the metal HAP emissions limit is demonstrated either 
using continuous opacity monitoring system (COMS) or continuous 
parameter monitoring system (CPMS). Owners or operators of FCCU are 
provided two options for demonstrating compliance with the PM limit 
during periods of startup, shutdown, or hot standby in 40 CFR 
63.1564(a)(5): Meeting the emission limit that applies during times 
other than startup, shutdown, or hot standby, or meeting a minimum 
cyclone face velocity limit. Similarly, the rule provides two options 
for demonstrating compliance with the CO limit during periods of 
startup and shutdown in 40 CFR 63.1565(a)(5): Meeting the emission 
limit that applies during times other than startup, shutdown, or hot 
standby, or meeting an excess oxygen limit in the exhaust from the 
catalyst regenerator.
    The Refinery MACT 2 standards also regulate HAP emissions from SRU 
vents by specifying sulfur dioxide (SO2), reduced sulfur 
compound, or total reduced sulfur limits as a surrogate for SRU HAP 
emissions. In the rule, compliance with the SRU HAP emissions limit is 
demonstrated using a continuous emission monitoring system (CEMS) or, 
when a thermal incinerator/oxidizer is used, compliance with the SRU 
HAP emissions limits is demonstrated using CPMS. The rule removes 
previous requirements to operate according to a site-specific startup, 
shutdown, and malfunction plan and instead finalizes standards that 
apply during all times, including additional standards that apply 
during

[[Page 6817]]

startup and shutdown periods. Three compliance options were provided 
for SRU owners or operators to demonstrate compliance during periods of 
startup and shutdown in 40 CFR 63.1568(a)(4) including: Meeting the 
emission limit that applies during times other than startup or 
shutdown, sending purge gases to a flare that meets the operating 
requirements contained in 40 CFR 63.670, or sending purge gases to a 
thermal oxidizer or incinerator that meets specific temperature and 
excess oxygen requirements.
    For owners or operators complying with any of the limits for 
startup, shutdown, or hot standby for FCCU and for startup or shutdown 
for SRU, the compliance date is the effective date of the rule 
(February 1, 2016, 60 days after the publication date of the rule). The 
compliance date for the maintenance vent provisions is also the 
effective date of the rule. In the next section of this preamble, we 
discuss some additional clarifications and technical corrections we are 
proposing to Table 11 of subpart CC to 40 CFR part 63, which is where 
the maintenance vent compliance times and other subpart CC compliance 
times are delineated.
    The EPA has received new information that the compliance dates for 
standards for maintenance vents and startup, shutdown, or hot standby 
for FCCU and for startup or shutdown for SRU do not allow sufficient 
time to install additional control equipment, if needed, and to 
complete the management of change process, which includes addressing 
safety concerns associated with potential operational or procedural 
changes. The management of change process, which is discussed in 
further detail in the next section of this preamble, includes the 
following: Evaluating the change, forming an internal team to 
accomplish the change, engineering the change, which could include 
developing new set points, installing new controls or alarms, assessing 
risk of chemical accidents and catastrophic events, updating associated 
plans and procedures, providing training, performing pre-startup safety 
reviews, and implementing the change as required by other regulatory 
programs. In order to accommodate these steps, we are proposing to 
amend the compliance dates for these provisions to 18 months after the 
effective date of the standards (i.e., August 1, 2017). These proposed 
revisions are limited to periods of maintenance, startup, and shutdown 
which are expected to occur relatively infrequently as compared to 
normal operations.

III. What actions are we proposing?

A. Compliance Dates for Standards Applicable to Maintenance Vents, FCCU 
and SRU During Startup and Shutdown and During Hot Standby for FCCU

    The EPA has received additional information (see Docket ID No. EPA-
HQ-OAR-2010-0682) that indicates that the compliance dates for 
standards for maintenance vents and periods of startup, shutdown, and 
hot standby for FCCU and for startup or shutdown for SRU do not provide 
facilities sufficient time to go through their management of change 
process, which includes addressing safety concerns associated with 
potential operational or procedural changes and coordinating any 
changes with other applicable regulatory requirements. The process 
equipment associated with maintenance vents, FCCU, and SRU are subject 
to requirements under the Risk Management Program regulation in 40 CFR 
part 68 and the Occupational Safety and Health Administration (OSHA) 
Process Safety Management (PSM) standard in 29 CFR part 1910. Thus, any 
operational or procedural changes resulting from complying with the 
applicable standards must follow the management of change procedures in 
these respective regulatory programs.
    The Risk Management Program and OSHA PSM regulations provide that 
owners or operators follow a management of change process, as codified 
in 40 CFR 68.75, 29 CFR 1910.119(l) and appendix C of 29 CFR 1910.119, 
to ensure that the following are considered prior to making a change:
     The technical basis for the proposed change;
     Impact of change on safety and health;
     Modifications to operating procedures;
     Necessary time period for the change; and
     Authorization requirements for the proposed change.
    As part of the management of change process, the EPA expects that 
facilities will have to perform an upfront assessment to determine what 
changes are required to meet the new maintenance vent requirements and 
standards for FCCU and SRU. Based on our review of information brought 
forward by industry representatives, refinery owners or operators may 
have to adjust or install new instrumentation, including alarms, closed 
drain headers, equipment blowdown drums, and other new or revised 
processes and controls in order to comply with these new provisions. 
Facilities may also have to hire a vendor to assist with the project 
and complete the procurement process. Additionally, we anticipate that 
facilities will have to assess risk of chemical accidents and 
catastrophic events and review and revise standard operating 
procedures, as necessary.
    Further, the management of change provisions also require that 
employees who are involved in operating a process and maintenance and 
contract employees whose job tasks are affected by the change must be 
trained prior to startup of the affected process.
    Finally, facilities are required to conduct pre-startup safety 
reviews and obtain authorization for use to fully implement and startup 
the modified process and/or equipment.
    Therefore, to account for the applicable requirements in the Risk 
Management Program regulation and OSHA PSM standard, the EPA is 
proposing to require owners and operators of sources that were 
constructed or reconstructed on or before June 30, 2014, to comply with 
the maintenance vent provisions and limits for startup, shutdown, or 
hot standby for FCCU and for startup or shutdown for SRU no later than 
18 months after the effective date of the December 2015 rule. We 
believe that this additional time is both appropriate and sufficient to 
accomplish the necessary compliance-related tasks discussed above.
    Although not common, the possibility exists that some facilities 
may have to install new controls or otherwise invest in capital 
projects in order to comply with these new regulatory provisions. As 
provided in the General Provisions to part 63, owners or operators of 
these facilities can request an additional 12 months to comply with the 
standards using the provisions in 40 CFR 63.6(i).
    Owners and operators must comply with the general duty requirements 
in 40 CFR 63.642(n) for maintenance vents and 40 CFR 63.1570 for FCCU 
or SRU during periods of startup, shutdown and, for FCCU only, hot 
standby from the effective date of the December 2015 final rule until 
they comply with the new requirements on or before the applicable 
compliance dates. Records of compliance with the general duty 
requirements must be maintained as specified in 40 CFR 63.643(d), 
63.642(n) and 63.1570(c).

B. Clarifications and Technical Corrections

    We are proposing to make clarifying revisions to Table 11 in 40 CFR 
part 63, subpart CC. We received numerous questions regarding the 
compliance date for maintenance vents and some owners or operators are 
interpreting Table 11 to

[[Page 6818]]

provide 3 years to comply with the maintenance vent provisions 
established in the rule as well as with other requirements that were 
not amended in the rule. This was not our intent, and we do not 
interpret Table 11 to allow 3 years to comply with the provisions in 40 
CFR 63.643, or 3 years to comply with any of the requirements in 
subpart CC that were not amended in the December 2015 rule. However, in 
reviewing Table 11, we do understand the confusion, and we are 
proposing a revised version of Table 11 to more clearly delineate the 
compliance dates for the various provisions in subpart CC and to 
reflect the compliance date proposed for the maintenance vent 
provisions in the previous section of this preamble.
    The EPA is also proposing to make several clarifications and 
technical corrections as described here and summarized in the table 
below. The first sentence in Sec.  60.102a(f)(1)(i) is being changed to 
incorporate the pollutant of concern, SO2, directly into the 
regulatory text rather than inside a parenthesis within the sentence 
for clarity. A grammatical correction is being made to the closed 
blowdown system definition in Sec.  63.641 by adding an ``a'' before 
the phrase, ``. . . process vessel to a control device or back into the 
process.'' The term ``relief valve'' and ``valve'' are being replaced 
with ``pressure relief device'' and ``device'' in the force majeure 
event definition in Sec. Sec.  63.641 and 63.670(o)(1)(ii)(B), 
respectively. These changes are being made to improve consistency in 
the use of the term ``pressure relief device'' as it pertains to the 
work practice requirements in Sec.  63.648(j) and associated 
provisions. The list of exceptions for equipment leak requirements in 
Sec.  63.648(a) is being expanded to ensure the intent of the 
rulemaking is clear, that pressure relief devices subject to the 
requirements in either 40 CFR part 60, subpart VV or part 63, subpart H 
and the requirements in 40 CFR part 63, subpart CC are to comply with 
the requirements in Sec.  63.648(j)(1) and (2), instead of the pressure 
relief device requirements in 40 CFR part 60, subpart VV and 40 CFR 
part 63, subpart H. The reporting and recordkeeping requirements 
related to fenceline monitoring contained in Sec.  63.655(h)(8) are 
being edited to provide clarity that compliance reports are due 45 days 
after the end of each reporting period. The term ``periodic'' in the 
context of the report for fenceline monitoring has been removed to 
avoid confusion concerning the due dates of other periodic reports 
contained in 40 CFR part 63, subpart CC such as those specified in 
Sec.  63.655(g). The siting requirements for passive monitors near 
known sources of volatile organic compounds (VOC) contained in Sec.  
63.658(c)(1) are being edited to clarify that a monitor should be 
placed on the shoreline adjacent to the dock for marine vessel loading 
operations. The phrase ``that are located offshore'' was removed 
because the intent is to require a monitor on the shoreline adjacent to 
the dock for marine vessel loading operations, and is not dependent on 
whether the location of the marine vessel loading operation is onshore 
or offshore.
    The EPA is also proposing to add language to clarify the effective 
dates of two specific provisions in 40 CFR part 63, subpart UUU. First, 
we are proposing to revise the catalytic reforming unit (CRU) pressure 
limit exclusion provision in 40 CFR 63.1566(a)(4) to specify that 
refiners have 3 years to comply with the requirements to meet emission 
limitations in Tables 15 and 16 if they actively purge or depressurize 
at vessel pressures of 5 psig or less. Although both the proposal and 
the final preambles (at 79 FR 36950 and 80 FR 75185) indicated that we 
intended to provide a 3-year compliance period, language in Sec.  
63.1566(a)(4) did not specifically provide 3 years. This was an 
inadvertent omission and in this action we are proposing to add rule 
language to reflect our intent.
    Similarly, we are proposing to revise the entry for item 1 in Table 
2 of subpart UUU to clarify that refineries have 18 months to comply 
with the 20 percent opacity operating limit for units subject to 
Refinery NSPS subpart J or electing to comply with Refinery NSPS 
subpart J provisions for PM. Although both the proposal and the final 
preambles (at 79 FR 36950 and 80 FR 75185) indicated that we intended 
to provide an 18-month compliance period for new or revised operating 
limits for FCCU, the language in Table 2 of subpart UUU did not 
specifically provide this 18 month compliance period. Again, this was 
an inadvertent omission and in this action we are proposing to add rule 
language to reflect our intent.
    Additionally, the reference to Sec.  60.102a(b)(1) in Sec.  
63.1564(a)(1)(iv) is being removed as this provision should only 
reference Option 2 in Table 1 (Item 7 in Table 1 of part 63, subpart 
UUU), providing owners or operators with the option to comply with the 
Refinery MACT 2 p.m. option when they choose not to comply with one of 
the NSPS options. A typographical correction is being made to the 
reference to Sec.  63.1566(a)(5)(iii) in 40 CFR part 63, subpart UUU, 
Table 3, Item 12 to correctly reference Sec.  63.1564(a)(5)(ii). 
Finally, an editorial correction is being made to add the word ``and'' 
in place of a semicolon in 40 CFR part 63, subpart UUU, Table 5, Item 
2.

C. Impacts

    We expect the additional compliance time will have an insignificant 
effect on emission reductions and costs, as many refiners already have 
measures in place due to state and other federal requirements to 
minimize emissions during these periods. Further, these periods are 
relatively infrequent (some only occur on a 5-year cycle) and are 
usually of short duration.

IV. Statutory and Executive Order Reviews

    Additional information about these statutes and Executive Orders 
can be found at http://www2.epa.gov/laws-regulations//laws-and-executive-orders.

A. Executive Order 12866: Regulatory Planning and Review and Executive 
Order 13563: Improving Regulation and Regulatory Review

    This action is not a significant regulatory action and was, 
therefore, not submitted to the Office of Management and Budget (OMB) 
for review.

B. Paperwork Reduction Act (PRA)

    This action does not impose any new information collection burden 
under the PRA. OMB has previously approved the information collection 
activities contained in the existing regulations at 40 CFR part 63, 
subparts CC and UUU under the provisions of the Paperwork Reduction 
Act, 44 U.S.C. 3501 et seq. and has assigned OMB control numbers 2060-
0340 and 2060-0554. The proposed amendments are revisions to compliance 
dates, clarifications and technical corrections that do not affect the 
estimated burden of the existing rule. Therefore, we have not revised 
the information collection request for the existing rule.

C. Regulatory Flexibility Act (RFA)

    I certify that this action will not have a significant economic 
impact on a substantial number of small entities under the RFA. In 
making this determination, the impact of concern is any significant 
adverse economic impact on small entities. An agency may certify that a 
rule will not have a significant economic impact on a substantial 
number of small entities if the rule relieves regulatory burden, has no 
net burden, or otherwise has a positive economic effect on the small 
entities subject to the rule. The action consists of revisions to 
compliance dates, clarifications, and technical corrections which do 
not change the expected economic impact analysis performed for the 
existing rule. We have, therefore, concluded that this action will have 
no net regulatory burden for all directly regulated small entities.

D. Unfunded Mandates Reform Act (UMRA)

    This action does not contain any unfunded mandate as described in 
UMRA, 2 U.S.C. 1531-1538, and does not significantly or uniquely affect 
small governments. The action imposes no enforceable duty on any state, 
local, or tribal governments or the private sector.

E. Executive Order 13132: Federalism

    This action 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.

F. Executive Order 13175: Consultation and Coordination With Indian 
Tribal Governments

    This action does not have tribal implications as specified in 
Executive Order 13175. It will not have substantial direct effect 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 action.

G. Executive Order 13045: Protection of Children From Environmental 
Health Risks and Safety Risks

    This action is not subject to Executive Order 13045 because it is 
not economically significant as defined in Executive Order 12866, and 
because the EPA does not believe the environmental health or safety 
risks addressed by this action present a disproportionate risk to 
children. The proposed amendments serve to revise compliance dates and 
make technical clarifications and corrections. We expect the additional 
compliance time will have an insignificant effect on emission 
reductions as many refiners already have measures in place due to state 
and other federal requirements to minimize emissions during these 
periods. Further, these periods are relatively infrequent and are 
usually of short duration. Therefore, the proposed amendments should 
not appreciably increase risk for any populations. Further, this action 
will allow more time for refiners to implement procedures to safely 
start up and shut down equipment which should minimize safety risks for 
all populations.

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

    This action is not subject to Executive Order 13211 because it is 
not a significant regulatory action under Executive Order 12866.

I. National Technology Transfer and Advancement Act (NTTAA)

    This rulemaking does not involve technical standards.

J. Executive Order 12898: Federal Actions To Address Environmental 
Justice in Minority Populations and Low-Income Populations

    The EPA believes the human health or environmental risk addressed 
by this action will not have potential disproportionately high and 
adverse human health or environmental effects on minority, low-income, 
or indigenous populations. The proposed amendments serve to revise 
compliance dates and make technical clarifications and corrections. We 
expect the additional compliance time will have an insignificant effect 
on emission reductions as many refiners already have measures in place 
due to state and other federal requirements to minimize emissions 
during these periods. Further, these periods are relatively infrequent 
and are usually of short duration. Therefore, the proposed amendments 
should not appreciably increase risk for any populations. Further, this 
action will allow more time for refiners to implement procedures to 
safely start up and shut down equipment which should minimize safety 
risks for all populations.
