National Emission Standards for Hazardous Air Pollutants and New 
Source Performance Standards: 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, which 
was published in the Federal Register on December 1, 2015, and 
subsequently amended on July 13, 2016. The December 1, 2015, action was 
the result of a risk and technology review in which the Environmental 
Protection Agency (EPA) finalized amendments to Refinery MACT 1 and 
Refinery MACT 2. The July 13, 2016, action finalized technical 
corrections and clarifications, as well as changes to compliance dates 
for various emission sources, including the maintenance vent standards 
that apply during periods of startup, shutdown, maintenance, or 
inspection. In this action, the EPA is proposing to amend the 
compliance dates for maintenance vents to January 30, 2019. These 
proposed revisions do not affect any other requirements in the December 
1, 2015, or July 13, 2016, final actions. This proposed action will 
have an insignificant effect on emissions reductions and no effect on 
costs.

I. General Information

A. Does this action apply to me?

    Table 1 of this preamble lists the NESHAP and associated regulated 
industrial source categories that are the subject of this proposal. 
Table 1 is not intended to be exhaustive, but rather provides a guide 
for readers regarding the entities that this proposed action is likely 
to affect. The proposed standards, once promulgated, will be directly 
applicable to the affected sources. Federal, state, local, and tribal 
government entities would not be affected by this proposed action. As 
defined in the Initial List of Categories of Sources Under Section 
112(c)(1) of the Clean Air Act Amendments of 1990 (see 57 FR 31576, 
July 16, 1992), the category titled Petroleum Refineries--Other Sources 
Not Distinctly Listed includes any facility engaged in producing 
gasoline, napthas, kerosene, jet fuels, distillate fuel oils, residual 
fuel oils, lubricants, or other products from crude oil or unfinished 
petroleum derivatives. This category includes all refinery emission 
sources except for three process vent sources listed in the Petroleum 
Refineries--Catalytic Cracking (Fluid and Other) Units, Catalytic 
Reforming Units, and Sulfur Plant Units source category. The refinery 
process units in the Petroleum Refineries--Other Sources Not Distinctly 
Listed source category include, but are not limited to, thermal 
cracking, vacuum distillation, crude distillation, hydroheating/
hydrorefining, isomerization, polymerization, lube oil processing, and 
hydrogen production.

publication in the Federal Register, the EPA will post the Federal 
Register version of the proposal and key technical documents at this 
same website.
    A redline version of the regulatory language that incorporates the 
proposed changes in this action is available in the docket for this 
action (Docket ID No. EPA-HQ-OAR-2010-0682).

II. Background

    The EPA initially promulgated NESHAP pursuant to the Clean Air Act 
(CAA) sections 112(d)(2) and (3) for major sources in the Petroleum 
Refineries--Other Sources Not Distinctly Listed source category on 
August 18, 1995, in 40 CFR part 63, subpart CC. These standards are 
also referred to as maximum achievable control technology (MACT) 
standards and this NESHAP for petroleum refineries is commonly referred 
to as Refinery MACT 1. The 1995 Refinery MACT 1 rule regulates 
miscellaneous process vents, storage vessels, wastewater, equipment 
leaks, gasoline loading racks, and marine tank vessel loading. On 
October 28, 2009, the EPA promulgated amendments to Refinery MACT 1 to 
include MACT standards for heat exchange systems, which were not 
originally addressed in Refinery MACT 1. This same rulemaking included 
updating cross-references to the General Provisions in 40 CFR part 63.
    The EPA completed a residual risk and technology review of Refinery 
MACT 1, publishing final amendments on December 1, 2015. The December 
1, 2015, final amendments included revisions to the Refinery MACT 1 
requirements for process vents designated as ``maintenance vents.'' 
Maintenance vents are used only during startup, shutdown, maintenance, 
or inspection of equipment activities during which the equipment is 
emptied, depressurized, degassed, or placed into service. The December 
1, 2015, final amendments require that the hydrocarbon content of the 
vapor in the equipment served by the maintenance

[[Page 31942]]

vent to be less than or equal to 10 percent of the lower explosive 
limit (LEL) prior to venting to the atmosphere. The December 1, 2015, 
final rule also provides specific allowances for situations when the 
10-percent LEL cannot be demonstrated or is technically infeasible. The 
compliance date included in the December 1, 2015, final rule for 
maintenance vents located at sources constructed on or before June 30, 
2014, was February 1, 2016 (the effective date of the December 1, 2015, 
final amendments).
    On January 19, 2016, the EPA received a petition for 
reconsideration from the American Petroleum Institute (API) and the 
American Fuel and Petrochemical Manufacturers (AFPM) formally 
requesting that the EPA reconsider the compliance date for maintenance 
vents located at sources constructed on or before June 30, 2014, among 
other issues.
    In response to this petition, on July 13, 2016, the EPA revised the 
compliance date for maintenance vents located at sources constructed on 
or before June 30, 2014, from February 1, 2016, to August 1, 2017 (81 
FR 45232; July 13, 2016).

III. What actions are we proposing?

    In this action, the EPA is proposing to revise the compliance date 
for maintenance vents located at sources constructed on or before June 
30, 2014, from August 1, 2017, to January 30, 2019. This proposed 
compliance date would provide petroleum refinery owners or operators 
with an additional 18 months to achieve compliance. The EPA is aware 
that many refineries have made good faith efforts to achieve 
compliance, including applying for and receiving an additional 12-month 
compliance extension. This makes their compliance deadline August 1, 
2018, under the procedures provided in the General Provisions at 40 CFR 
63.6(i). The compliance date included in this proposal (i.e., January 
30, 2019) is 3 years from the effective date of the December 1, 2015, 
final rule (i.e., February 1, 2016). This proposed compliance date is 
consistent with CAA section 112(i)(3)(A), which specifies that the EPA 
provide a compliance date no more than 3 years after the effective date 
of the standard.
    The EPA is proposing to amend the compliance date due to challenges 
petroleum refinery owners or operators have experienced in attempting 
to comply with the December 1, 2015, final rule requirements 
notwithstanding the additional compliance time provided in the July 13, 
2016, final rule (i.e., August 1, 2017) and the compliance extension 
procedure in 40 CFR 63.6(i) (i.e., August 1, 2018). The new 
requirements for maintenance vents promulgated in the December 1, 2015, 
rule resulted in the need for completing the ``management of change 
process'' for affected sources (81 FR 45232, 45237, July 13, 2016). The 
management of change process includes 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, conducting risk assessments, updating associated plans and 
procedures, providing training, performing pre-startup safety reviews, 
and implementing the change as required by other regulatory programs. 
Some refinery owners or operators have also indicated the need to 
install additional control equipment to meet the new requirements, 
which would require additional engineering design, site preparation, 
and installation.
    Additionally, the EPA has received various requests from industry 
stakeholders for clarification regarding the maintenance vent 
provisions.\1\ \2\ \3\ \4\ In consideration of these submissions, the 
EPA has proposed technical corrections and clarifications for 
maintenance vents in a proposed rule which was published in the Federal 
Register on April 10, 2018. The public comment period for this proposed 
rule closed on May 25, 2018. The April 10, 2018, proposed rule directly 
affects compliance for maintenance vents and, therefore, creates 
uncertainty for affected sources, affecting the ability of refinery 
owners or operators to fully invest in compliance solutions.

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

    A compliance date of January 30, 2019, will provide sufficient time 
for the EPA to take final action on the April 10, 2018, proposal, and 
sufficient time for sources to complete the management of change 
process and to fully invest in compliance solutions.

IV. Summary of Cost, Environmental, and Economic Impacts

    The additional compliance time will have an insignificant effect on 
emission reductions and no effect on costs. The amount of time the 
maintenance vents are used are relatively infrequent and are usually of 
short duration (81 FR 45237, July 13, 2016). In addition, the proposed 
compliance date only provides approximately 6 months additional time 
beyond the August 1, 2018, compliance date for facilities that received 
a compliance extension under the procedure in 40 CFR 63.6(i).

V. Statutory and Executive Order Reviews

    Additional information about these statutes and Executive Orders 
can be found at https://www.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. Executive Order 13771: Reducing Regulations and Controlling 
Regulatory Costs

    This action is not expected to be an Executive Order 13771 
regulatory action because this action is not significant under 
Executive Order 12866.

C. Paperwork Reduction Act (PRA)

    This action does not impose any new information collection burden 
under the PRA. The 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 PRA, 44 U.S.C. 
3501 et seq., and has assigned the OMB control numbers 2060-0340 and 
2060-0554. The proposed amendments are revisions to compliance dates 
that do not affect the estimated burden of the existing rule. 
Therefore, we have not revised the information collection request for 
the existing rule.

D. 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

[[Page 31943]]

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 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.

E. 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.

F. Executive Order 13132: Federalism

    This action does not have federalism implications. It will not have 
substantial direct effects on the states, the relationship between the 
national government and the states, or the distribution of power and 
responsibilities among the various levels of government.

G. 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.

H. 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 revise compliance dates. 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.

I. 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.

J. National Technology Transfer and Advancement Act (NTTAA)

    This rulemaking does not involve technical standards.

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

    The EPA believes that this action does not have disproportionately 
high and adverse human health or environmental effects on minority 
populations, low-income populations and/or indigenous peoples, as 
specified in Executive Order 12898 (59 FR 7629, February 16, 1994). The 
proposed amendments revise compliance dates. 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. 
Additionally, the proposed compliance date only provides approximately 
6 months beyond the August 1, 2018, compliance date for facilities 
operating under the compliance extension procedure in 40 CFR 63.6(i). 
Therefore, the proposed amendments should not appreciably increase risk 
for any populations.
