National Emission Standards for Hazardous Air Pollutants: 
Reciprocating Internal Combustion Engines and New Source Performance 
Standards: Internal Combustion Engines; Electronic Reporting

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is finalizing 
amendments to the National Emission Standards for Hazardous Air 
Pollutants (NESHAP) for Reciprocating Internal Combustion Engines 
(RICE), the New Source Performance Standards (NSPS) for Stationary 
Compression Ignition (CI) Internal Combustion Engines, and the NSPS for 
Stationary Spark Ignition (SI) Internal Combustion Engines, to add 
electronic reporting provisions. The addition of electronic reporting 
provisions will provide for simplified reporting by sources and enhance 
availability of data on sources to the EPA and the public. In addition, 
a small number of clarifications and corrections to these rules are 
being finalized to provide clarification and correct inadvertent and 
other minor errors in the Code of Federal Regulations (CFR), 
particularly related to tables.

DATES: This final rule is effective on August 30, 2024.

C. Judicial Review and Administrative Review

    Under Clean Air Act (CAA) section 307(b)(1), judicial review of 
this final action is available only by filing a petition for review in 
the United States Court of Appeals for the District of Columbia Circuit 
(the court) by October 29, 2024. Under CAA section 307(b)(2), the 
requirements established by this final rule may not be challenged 
separately in any civil or criminal proceedings brought by the EPA to 
enforce the requirements.
    Section 307(d)(7)(B) of the CAA further provides that ``[o]nly an 
objection to a rule or procedure which was raised with reasonable 
specificity during the period for public comment (including any public 
hearing) may be raised during judicial review.'' This section also 
provides a mechanism for the EPA to convene a proceeding for 
reconsideration, ``[i]f the person raising an objection can demonstrate 
to the EPA that it was impracticable to raise such objection within 
[the period for public comment] or if the grounds for such objection 
arose after the period for public comment, (but within the time 
specified for judicial review) and if such objection is of central 
relevance to the outcome of the rule.'' Any person seeking to make such 
a demonstration to us should submit a Petition for Reconsideration to 
the Office of the Administrator, U.S. Environmental Protection Agency, 
Room 3000, WJC West Building, 1200 Pennsylvania Ave. NW, Washington, DC 
20460, with a copy to both the person listed in the preceding FOR 
FURTHER INFORMATION CONTACT section, and the Associate General Counsel 
for the Air and Radiation Law Office, Office of General Counsel (Mail 
Code 2344A), U.S. Environmental Protection Agency, 1200 Pennsylvania 
Ave. NW, Washington, DC 20460.

II. Background

    Stationary engines are used in a variety of applications from 
generating electricity to powering pumps and compressors in power and 
manufacturing plants. They are also used in the event of an emergency 
such as fire or flood. The key air pollutants the EPA regulates from 
these sources include formaldehyde, acetaldehyde, acrolein, methanol, 
polycyclic aromatic hydrocarbon, volatile organic compounds, carbon 
monoxide, nitrogen oxides, particulate matter, sulfur dioxide, and 
hydrocarbons.
    A CI engine, or diesel engine, is a type of engine in which the 
fuel injected into the combustion chamber is ignited by a heat 
resulting from the compression of gases inside the cylinder. A SI 
engine is a type of engine in which the fuel-air mixture in the 
combustion chamber is ignited by a spark from a spark plug.
    The NESHAP for RICE is codified in 40 CFR part 63, subpart ZZZZ, 
which was first promulgated in 2004. The NSPS for Stationary CI 
Internal Combustion Engines (ICE) is codified in 40 CFR part 60, 
subpart IIII, which was first promulgated in 2006. The NSPS for 
Stationary SI Internal Combustion Engines is codified in 40 CFR part 
60, subpart JJJJ, which was first promulgated in 2008. All have been 
amended several times since promulgation.

III. What changes did we propose and what changes are we finalizing?

A. Summary of Actions Proposed

    On June 26, 2023 (88 FR 41361), the EPA proposed the following 
pursuant to CAA sections 111 and 112: addition of requirements for 
electronic reporting to 40 CFR part 60, subpart IIII, 40 CFR part 60, 
subpart JJJJ, and 40 CFR part 63, subpart ZZZZ; clarifications to table 
4 in 40 CFR part 60, subpart IIII due to incorrect display in the CFR; 
the correction of inadvertent errors in 40 CFR part 63, subpart ZZZZ, 
specifically in 40 CFR 63.6625(j) the need to reference additional line 
items in table 2d; and clarifications to the oil change requirements 
for certain engines as referenced in 40 CFR part 63, subpart ZZZZ, 
tables 2c and 2d. The following sections discuss the proposed changes 
in more detail, along with significant comments received and the EPA's 
response to those comments, and the final amendments to the rules, 
including any changes to what was proposed that are being made as a 
result of comments received. For additional comments and responses, 
please see the document, Summary of Public Comments and EPA's Responses 
National Emission Standards for Hazardous Air Pollutants: Reciprocating 
Internal Combustion Engines and New Source Performance Standards: 
Internal Combustion Engines; Electronic Reporting, available in the 
docket for this action. The EPA also solicited comments to aid in its 
consideration of the appropriate next steps following remand of the 
provisions specifying that emergency engines can operate for up to 50 
hours per year to mitigate local transmission and/or distribution 
limitations to avert potential voltage collapse or line overloads that 
could lead to the interruption of power supply in a local area or 
region by the court. The EPA appreciates the comments and information 
that were provided during the public comment period and will consider 
them as it assesses the appropriate path forward but is not responding 
to these comments or taking further action on these provisions at this 
time.

B. Electronic Reporting

    The EPA proposed that owners and operators of stationary engines 
subject to NSPS subparts IIII or JJJJ, or NESHAP subpart ZZZZ, submit 
electronic copies of certain initial notifications of compliance, 
performance test reports, Notification of Compliance Status (NOCS), and 
annual and semiannual compliance reports through the EPA's Central Data 
Exchange (CDX) using the Compliance and Emissions Data Reporting 
Interface (CEDRI). A description of the electronic data submission 
process was provided in the memorandum Electronic Reporting 
Requirements for New Source Performance Standards (NSPS) and National 
Emission Standards for Hazardous Air Pollutants (NESHAP) Rules and was 
placed in the docket at the time of proposal. The EPA proposed that the 
initial notification of compliance be submitted through CEDRI, that 
performance test results collected using test methods that are 
supported by the EPA's Electronic Reporting Tool (ERT) as listed on the

[[Page 70507]]

ERT website \1\ at the time of the test be submitted in the format 
generated through the use of the ERT or an electronic file consistent 
with the extensible markup language (XML) schema on the ERT website, 
and that other performance test results be submitted in portable 
document format (PDF) using the attachment module of the ERT. The EPA 
also proposed that NOCS for NESHAP subpart ZZZZ be submitted as a PDF 
upload in CEDRI.
---------------------------------------------------------------------------

    \1\ https://www.epa.gov/electronic-reporting-air-emissions/electronic-reporting-tool-ert.
---------------------------------------------------------------------------

    For annual and semiannual compliance reports, the EPA proposed that 
owners and operators use the appropriate spreadsheet template to submit 
information to CEDRI. Draft versions of the proposed templates for 
these reports were included in the docket at the time of proposal.\2\ 
The EPA specifically requested comment on the content, layout, and 
overall design of the templates.
---------------------------------------------------------------------------

    \2\ See 
60.4214d3_annual_report_bulk_upload_template_ICRDraft.xlsx, 
60.4245e3_annual_report_bulk_upload_template_ICRDraft.xlsx, and 
63.6650_h_and_i Compliance Report Template_ICRDraft.xlsm, available 
at Docket ID. No. EPA-HQ-OAR-2022-0879.
---------------------------------------------------------------------------

    Additionally, the EPA identified two broad circumstances in which 
electronic reporting extensions may be provided. These circumstances 
were: (1) outages of the EPA's CDX or CEDRI which preclude an owner or 
operator from accessing the system and submitting required reports and 
(2) force majeure events, which are defined as events that will be or 
have been caused by circumstances beyond the control of the affected 
facility, its contractors, or any entity controlled by the affected 
facility that prevent an owner or operator from complying with the 
requirement to submit a report electronically. Examples of force 
majeure events are acts of nature, acts of war or terrorism, or 
equipment failure or safety hazards beyond the control of the facility. 
The EPA provided these potential extensions to protect owners and 
operators from noncompliance in cases where they cannot successfully 
submit a report by the reporting deadline for reasons outside of their 
control. In both circumstances, the decision to accept the claim of 
needing additional time to report is within the discretion of the 
Administrator, and reporting should occur as soon as possible.
    As described in the proposed rulemaking, the electronic submittal 
of the reports addressed in this final rule will increase the 
usefulness of the data contained in those reports, is in keeping with 
current trends in data availability and transparency, will further 
assist in the protection of public health and the environment, will 
improve compliance by facilitating the ability of regulated facilities 
to demonstrate compliance with requirements and by facilitating the 
ability of delegated State, local, Tribal, and territorial air agencies 
and the EPA to assess and determine compliance, and will ultimately 
reduce burden on regulated facilities, delegated air agencies, and the 
EPA. Electronic reporting eliminates paper-based, manual processes, 
thereby saving time and resources, simplifying data entry, eliminating 
redundancies, minimizing data reporting errors, and providing data 
quickly and accurately to the affected facilities, air agencies, the 
EPA, and the public. Moreover, electronic reporting is consistent with 
the EPA's plan \3\ to implement Executive Order 13563 and is in keeping 
with the EPA's agency-wide policy \4\ developed in response to the 
White House's Digital Government Strategy.\5\ For more information on 
the benefits of electronic reporting, see the memorandum Electronic 
Reporting Requirements for New Source Performance Standards (NSPS) and 
National Emission Standards for Hazardous Air Pollutants (NESHAP) 
Rules, available in the docket for this action.

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

    As part of the electronic reporting effort, reporting requirements 
in NESHAP subpart ZZZZ were clarified and adjusted to be consistent for 
all engine types as well as to provide specificity in units of measure 
and to provide consistency between the NSPS and the NESHAP. With these 
changes, the regulatory text in 40 CFR part 63, subpart ZZZZ at 40 CFR 
63.6650 now includes all the applicable data elements required by 40 
CFR 63.10(e)(3), and the general provisions applicability table is 
being revised to reflect that 40 CFR 63.10(e)(3) is no longer 
applicable.
    We received comments both in support of, and opposed to, the 
addition of electronic reporting provisions, as well as several 
comments regarding the draft electronic reporting templates that were 
made available in the docket. In response to these comments, we made 
some clarifying changes to the templates. We address and respond to 
these comments in detail in the response to comment document available 
in the docket for this action.
    One clarifying change made in response to comments was to alter the 
regulatory text and the corresponding entry in the final reporting 
template for subpart ZZZZ to require the year the engine was 
constructed, rather than the specific date. Additionally, if the exact 
year is unknown, an estimate can be provided.
    The Department of Defense (DoD) commented that all templates 
provided for review have a requirement to provide the latitude and 
longitude of the engine in decimal degrees reported to the fifth 
decimal place, but due to the present-day public availability of 
electronic data files, DoD is concerned that disclosing the location of 
certain engines used by the commenter can compromise national security. 
The comment requested the EPA consider including an option for template 
latitude and longitude data fields that would allow an installation to 
label critical system geolocation data as ``confidential'' or 
``national security information.'' By offering such an option, the 
commenter's national security data would not be disclosed or 
retrievable through publicly available agency (Federal/state/local/
tribal) electronic data systems.
    The EPA agrees that the exact location of engines should not be 
reported if the location should remain confidential due to national 
security concerns. The EPA has clarified for the final rule that if 
disclosure of the exact location of an engine that is owned by or 
operated by or for an agency of the Federal Government that is 
responsible for national defense would be a threat to national 
security, the filer may claim a national security exemption, which will 
allow the latitude and longitude fields in the reporting template to be 
left blank. A corresponding revision is also being made to the 
regulatory text. It should be noted that the reports still contain the 
address of the facility at which the engine(s) are located.\6\
---------------------------------------------------------------------------

    \6\ The comment also suggested that the EPA should establish 
criteria for access to precise geolocation of sources in all 
appropriate stationary engine (NESHAP and NSPS) rules. The EPA does 
not find it necessary to adopt such criteria at this time, 
particularly since facility address data is still required to be 
reported but will work with other agencies to address this issue in 
the future if it becomes appropriate.

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

C. Clarifications to Table 4 in NSPS Subpart IIII

    Since it was originally published in the CFR, ``Table 4 to Subpart 
IIII of Part 60--Emission Standards for Stationary Fire Pump Engines'' 
has been confusing to the public because it shows blank cells for the 
CO standard for certain engine model years. The table intended to show 
that the same CO standard applies for all model years. The table was 
not intended to be displayed in this manner and the current version 
simply reflects a mismatch between what was submitted by the EPA and 
what was able to be shown in the CFR. The EPA invited comment on 
whether any other aspect of this table was confusing or incorrect (it 
was shown as table 1 in the preamble of the proposal), but we did not 
solicit comment on any proposed changes to the standards themselves.
    We received comment supporting the clarified table and further 
suggesting that the units of the engine emission standards be added, 
similar to how the units are currently shown in tables 1 and 2 of 40 
CFR part 60, subpart IIII, to prevent any potential confusion regarding 
the applicable emission standards. We agree that this suggestion would 
provide further clarification and prevent additional confusion. We are, 
therefore, finalizing the clarifications to this table as proposed and 
additionally placing units in the column heading of the table as shown 
in table 1 of this document.

\3\ In model years 2009-2011, manufacturers of fire pump stationary CI ICE in this engine power category with a
  rated speed of greater than 2,650 rpm may comply with the emission limitations for 2008 model year engines.

D. Correction of Inadvertent Errors in NESHAP Subpart ZZZZ

    As it appeared in the CFR at the time of the proposal, table 2d in 
40 CFR part 63, subpart ZZZZ correctly indicated multiple SI engine 
types for which oil change requirements apply. Specifically, table 2d's 
items numbers 5, 6, 7, 8, 10, 11, and 13 all indicated SI engine types 
for which these requirements apply. When this table was last 
revised,\7\ corresponding changes to 40 CFR 63.6625(j) were 
inadvertently not made. As a result, the version of 40 CFR 63.6625(j), 
which specifies that an oil analysis program can be used to extend the 
oil change requirements, referred to an incorrect set of table 2d's 
item numbers. Therefore, the EPA proposed to amend 40 CFR 63.6625(j) to 
include the correct list of table 2d's item numbers, specifically 5, 6, 
7, 8, 10, 11, and 13, that indicate SI engine types for which oil 
change requirements apply.
---------------------------------------------------------------------------

    \7\ 78 FR 6709 (January 30, 2013).
---------------------------------------------------------------------------

    We received no comments opposing this correction and received only 
one comment in general support of it. Therefore, we are finalizing the 
correction as proposed.

E. Clarifications to the Oil Change Requirement in NESHAP Subpart ZZZZ

    As indicated in tables 2c and 2d of 40 CFR part 63, subpart ZZZZ, 
several types of CI and SI engines are subject to oil change 
requirements. The number of hours of operation allowed between oil 
changes stated in the requirement vary by engine type. However, in each 
instance, the requirement that appeared in the CFR at the time of the 
proposal was phrased in the form: ``Change oil and filter every X,XXX 
hours of operation or annually, whichever comes first.''
    The EPA receives frequent inquiries from regulated entities 
regarding these provisions, most often revolving around the meaning of 
the term ``annually.'' For example, regulated entities sometimes 
inquire whether ``annually'' means ``every calendar year.'' In such a 
case, the inquiry amounts to essentially whether an oil change could 
hypothetically be conducted on January 1, 2019, and the next oil change 
could then be conducted on December 31, 2020, since 2020 is the 
calendar year that falls immediately after 2019 (this assumes of course 
that X,XXX hours of

[[Page 70509]]

operation has not occurred). In such a scenario, however, these two 
hypothetical oil changes will have actually occurred almost exactly 2 
years apart, minus a day.
    This is not what the EPA intended with the use of the term 
``annually'' in tables 2c and 2d of 40 CFR part 63, subpart ZZZZ. It is 
important for oil changes to occur as close as possible to 12 months 
apart to minimize emissions, absent use of the oil analysis programs 
afforded by 40 CFR 63.6625(i) and (j). The same language of 
``annually'' also appears in these tables related to items such as 
spark plug, air cleaner, and hose and belt inspections, and similar 
concerns about emissions and engine reliability apply. Therefore, the 
EPA proposed to replace each instance of use of the term ``annually'' 
in tables 2c and 2d with the term ``every 12 months.'' \8\
---------------------------------------------------------------------------

    \8\ Additionally, the same language of ``annually'' also in 
appears in a separate location in subpart ZZZZ, namely in the 
subsection on management practices applicable to existing stationary 
non-emergency CI RICE with a site rating of more than 300 HP located 
on an offshore vessel that is an area source of HAP and is a nonroad 
vehicle that is an Outer Continental Shelf source as defined in 40 
CFR 55.2. Similar concerns apply to the engines affected by this 
subsection (40 CFR 63.6603). So we, likewise, proposed to replace 
each instance of the term ``annually'' with the term ``every 12 
months'' there.
---------------------------------------------------------------------------

    The EPA received a number of comments on this issue, which are 
detailed in the response to comment document available in the docket. 
While some comments were generally supportive of the EPA's proposed 
change, commenters asked for additional flexibility beyond that 
afforded by the proposed language, mainly due to concerns about 
performing oil changes within a tight window in the case of unforeseen 
events or due to scheduling concerns for maintenance personnel or 
contractor availability. Most commenters favored an additional month of 
flexibility beyond the 12-month deadline.\9\ After considering these 
comments, we are making adjustments to the final language to state 
``within 1 year + 30 days of the previous change'' (and, in the case of 
items such as spark plug, air cleaner, and hose and belt inspections, 
``within 1 year + 30 days of the previous inspection'') in lieu of the 
current ``annually.'' The EPA continues to believe that it is 
appropriate for oil changes to be performed annually (i.e., after 365 
days) but is balancing the need for timely oil changes for proper 
emissions control against the practical concerns raised by commenters 
regarding scheduling oil changes in a tight window. Pursuant to this 
revised text, an oil change could hypothetically be conducted on June 
1, 2025, and the next oil change could then be conducted anywhere from 
June 2, 2025, to July 1, 2026, and be in compliance with the 
regulations. The EPA also finds that this revised language will address 
the request by some commenters for more clarity as to the deadline for 
oil changes. As explained at proposal, it is worthwhile to note that 
the EPA occasionally receives questions as to whether regulated 
entities that adopt the oil analysis program in 40 CFR 63.6625(i) or 
(j) must change the oil filter on a more frequent basis than the oil is 
changed even when the oil analysis program indicates condemning limits 
have not yet been reached for Total Acid or Total Base Number, 
viscosity, and percent water content. We are clarifying that regulated 
entities that adopt the oil analysis program must change the oil filter 
for these generators when changing the oil and are not required to 
change the filter prior to changing the oil. We received no comments 
opposing this clarification. The intention of the EPA's regulations is 
that the oil filter should always be changed whenever the engine oil is 
changed, and we are finalizing the proposed changes to the regulatory 
text to this effect. Also please note that nothing in the EPA's 
regulations prevents the owner and operator from changing the oil or 
the oil filter sooner than condemning limits have been reached, if 
desired.
---------------------------------------------------------------------------

    \9\ The EPA also is making it clear that we do not prohibit 
changing the oil earlier than 12 months if entities desire to do so 
(since this was raised in some comments).
---------------------------------------------------------------------------

F. Other Requests for Comments

    In addition to general comments on the proposal, we also asked for 
comments on the reporting template that was placed in the docket for 
this action. Several commenters suggested changes to the template and 
after considering these comments we have made minor clarifying changes 
to the template. These comments and our responses are discussed more 
fully in the response to comment document available in the docket for 
this action. A final template is also available in the docket for this 
action.
    The EPA also requested comments on the provisions specifying that 
emergency engines can operate for up to 50 hours per year to mitigate 
local transmission and/or distribution limitations to avert potential 
voltage collapse or line overloads that could lead to the interruption 
of power supply in a local area or region. These provisions appear in 
the NESHAP \10\ and both NSPS \11\ and are often referred to as the 
``50-hour provisions.'' The EPA did not propose any changes to the 50-
hour provisions, but as discussed in the proposal, solicited comments 
to aid in its consideration of the appropriate next steps following 
remand of the provisions by the court. The EPA appreciates the comments 
and information that were provided during the public comment period and 
is considering them as we assess the appropriate path forward. However, 
the EPA did not propose and is not finalizing, any changes to the 50-
hour provisions at this time; and we have not addressed those comments 
in the response to comments document for this final rule.
---------------------------------------------------------------------------

    \10\ 40 CFR 63.6640(f)(4)(ii).
    \11\ 40 CFR 60.4211(f)(3)(i), 40 CFR 60.4243(d)(3)(i).
---------------------------------------------------------------------------

G. Effective Date and Compliance Dates

    As stated in the proposal, the EPA's experience with other 
industries and entities that are required to convert reporting 
mechanisms, install necessary hardware and software, become familiar 
with the process of submitting performance test results electronically 
through the EPA's CEDRI, test these new electronic submission 
capabilities, reliably employ electronic reporting, and convert 
logistics of reporting processes to different time-reporting parameters 
shows that a time period of a minimum of 90 days, but more typically 
180 days, is generally necessary to successfully complete these 
changes. Due to the diverse nature of the stationary engine sector, the 
EPA proposed to allow 180 days from the date of the final rule for all 
electronic reporting provisions, and where a semiannual or annual 
report template is newly required, 180 days or 1 year from the date 
that the report template is made available on CEDRI, whichever is 
later, for compliance with the proposed electronic reporting 
requirements. For all other proposed requirements, because they are 
non-substantive edits simply to clarify existing requirements, the EPA 
proposed to make compliance effective immediately upon promulgation of 
the final rule.
    We received some comments asking for a longer compliance timeframe. 
The majority of these are addressed in the response to comment document 
available in the docket for this action, but in general, the commenters 
that asked for additional time to comply were generally mistaken about 
the steps required to make their systems compatible with electronic 
reporting. For sources that were already required to submit the annual 
reports via an

[[Page 70510]]

electronic template to CEDRI prior to this rulemaking (i.e., emergency 
stationary CI ICE subject to reporting under 40 CFR 60.4214(d) in 40 
CFR part 60, subpart IIII, emergency stationary SI ICE subject to 
reporting under 40 CFR 60.4245(e) in 40 CFR part 60, subpart JJJJ, and 
emergency stationary RICE subject to reporting under 40 CFR 63.6650(h) 
in 40 CFR part 63, subpart ZZZZ) the EPA determined that 180 days is 
sufficient time to adjust to the revised electronic template and 
accommodate the new reporting elements. For all other sources, the EPA 
determined that the additional year after the reporting template 
becomes available in CEDRI is necessary for these sources to begin 
electronic reporting. As discussed in the response to comments 
document, the EPA considers a year to be an adequate amount of time for 
these sources to adjust to electronic reporting. We are therefore 
finalizing the compliance timeframe as proposed.
    Pursuant to CAA sections 111(b)(1)(B) and 112(i), the revisions to 
the rules being promulgated in this action are effective on August 30, 
2024. The compliance date for affected sources to comply with the 
amendments pertaining to electronic reporting is 180 days after the 
effective date of the rule, or, where electronic reporting is newly 
required for semiannual or annual compliance reports, 1 year from the 
date that the respective report template is made available on CEDRI, 
whichever is later.

IV. Summary of Cost, Environmental, and Economic Impacts

A. What are the air quality impacts?

    No air quality impacts are expected to result from this rulemaking.

B. What are the cost impacts?

    The EPA estimated costs for this action are based on the results of 
the analysis for information collection activities, as presented in the 
Paperwork Reduction Act (PRA) section and accompanying Information 
Collection Request (ICR) documents in the docket.
    When assessed over the first 3 years of compliance, the incremental 
costs for both NSPS (subpart IIII and subpart JJJJ) are estimated to be 
negative, i.e., reflect a cost savings, for all 3 years. For the NESHAP 
(subpart ZZZZ), the incremental cost is estimated to have costs in 2025 
followed by cost savings in 2026 and 2027. When viewed on an overall 
basis (i.e., all subparts considered), undiscounted costs for the final 
rule, in 2021$, are $18.0 million in 2025, ($38.0 million) in 2026, and 
($38.2 million) in 2027, with parentheses indicating negative values, 
i.e., cost savings. Although the EPA also anticipates that the final 
rule will continue to result in cost savings in years beyond 2027 for 
all subparts, we have not estimated the magnitude or duration of these 
cost savings. These estimates are consistent with our experience that 
electronic reporting reduces burden on regulated entities (and the EPA) 
by eliminating paper-based processes and providing data quickly and 
accurately.
    More details on cost impact analyses for the final rule can be 
found in the ``What are the economic impacts?'' section of this 
preamble as well as in section 2 of the memorandum, Economic Impact and 
Small Business Analysis for the National Emission Standards for 
Hazardous Air Pollutants: Reciprocating Internal Combustion Engines and 
New Source Performance Standards: Internal Combustion Engines; 
Electronic Reporting Amendments, which is also available in the docket 
for this action.

C. What are the economic impacts?

    The EPA conducted economic impact analyses for the final rule, as 
detailed in the memorandum, Economic Impact and Small Business Analysis 
for the National Emission Standards for Hazardous Air Pollutants: 
Reciprocating Internal Combustion Engines and New Source Performance 
Standards: Internal Combustion Engines; Electronic Reporting 
Amendments, which is available in the docket for this action.
    Costs were estimated for the first 3 years following this action. 
Correspondingly, a 3-year period from 2025 to 2027 was selected as the 
best measure of the economic impacts of this action. This allowed for a 
reasonable and consistent timeframe over which to examine impacts of 
this action from a present value (PV) perspective. The PV in 2021 
dollars is a cost saving of approximately $53.8 million using a 2 
percent discount rate, a cost saving of approximately $51.8 using a 3 
percent discount rate, and a cost saving of approximately $44.5 million 
using a 7 percent discount rate.12 13 The equivalent 
annualized value (EAV), in 2021 dollars, is a cost saving of 
approximately $18.7 million using a discount rate of 2 percent, a cost 
saving of approximately $18.3 using a discount rate of 3 percent, and a 
cost saving of approximately $16.9 million using a discount rate of 7 
percent. The amendments to 40 CFR part 60, subparts IIII and JJJJ have 
estimated cost savings for respondents in each year. We conducted an 
analysis assessing the impacts of the costs associated with the 
amendments to 40 CFR part 63, subpart ZZZZ. As shown in the supporting 
statement to 40 CFR part 63, subpart ZZZZ, the amendments to ZZZZ have 
estimated costs of $32 per respondent for the first year and cost 
savings thereafter. As described the economic impact analysis, for the 
first year such costs are less than 0.1 percent of the average affected 
entity's payroll, and we conclude that it is reasonable to assume that 
such costs represent less than 0.1 percent of sales for the average 
affected entity.\14\
---------------------------------------------------------------------------

    \12\ Present value and equivalent annualized value calculations 
can be found in RICE--final--economic analysis.xls, a spreadsheet 
that includes the basis for the economic impacts that was generated 
by the EPA for this analysis report. This spreadsheet can be found 
in the docket for this rule.
    \13\ Results using the 2 percent discount rate were not included 
in the proposal for this action. The 2003 version of OMB's Circular 
A-4 had generally recommended 3 percent and 7 percent as default 
rates to discount social costs and benefits. The analysis of the 
proposed rule used these two recommended rates. In November 2023, 
OMB finalized an update to Circular A-4, in which it recommended the 
general application of a 2 percent rate to discount social costs and 
benefits (subject to regular updates), which is an estimate of 
consumption-based discount rate. We include cost results calculated 
using a 2 percent discount rate consistent with the update to 
Circular A-4 (OMB, 2023).
    \14\ The memorandum titled Economic Impact and Small Business 
Analysis for the Final National Emission Standards for Hazardous Air 
Pollutants: Reciprocating Internal Combustion Engines and New Source 
Performance Standards: Internal Combustion Engines; Electronic 
Reporting Amendment is available in the docket for this action.
---------------------------------------------------------------------------

    Given the results of the analysis, these economic impacts are 
relatively small for affected industries and entities impacted by this 
rule, and there will not be substantial impacts on the markets for 
affected products. The costs of the rule are not expected to result in 
a significant market impact, regardless of whether they are passed on 
to the purchaser or absorbed by the firms.

D. What are the benefits?

    The EPA is not making changes to the emission limits and estimates 
that the final requirements for electronic reporting are not 
economically significant. Because these amendments are not considered 
economically significant, as defined by Executive Order 12866, and 
because no emission reductions were projected, we are not estimating 
any benefits from reducing emissions.

V. Statutory and Executive Order Reviews

    Additional information about these statutes and Executive orders 
can be

[[Page 70511]]

found at https://www.epa.gov/laws-regulations/laws-and-executive-orders.

A. Executive Order 12866: Regulatory Planning and Review and Executive 
Order 14094: Modernizing Regulatory Review

    This action is not a significant regulatory action as defined in 
Executive Order 12866, as amended by Executive Order 14094, and was 
therefore not subject to a requirement for Executive Order 12866 
review.

B. Paperwork Reduction Act (PRA)

    The information collection activities in this rule have been 
submitted for approval to the Office of Management and Budget (OMB) 
under the PRA. The Information Collection Request (ICR) document that 
the EPA prepared has been assigned EPA ICR numbers 2196.08, 2227.07, 
and 1975.12 for NSPS subparts IIII and JJJJ, and NESHAP subpart ZZZZ, 
respectively. You can find a copy of the ICR in the docket for this 
rule, and it is briefly summarized here. The information collection 
requirements are not enforceable until OMB approves them.
    The amendments mainly add electronic reporting provisions to the 
rules. In general, the changes do not result in regulated entities 
needing to submit anything additional electronically that is not 
currently submitted via paper copies, and this is therefore expected to 
lessen the recordkeeping and reporting burden. The information is 
collected to assure compliance with 40 CFR part 60, subparts IIII and 
JJJJ and 40 CFR part 63, subpart ZZZZ.
    Respondents/affected entities: Owners and operators of stationary 
RICE at either a major or area source of HAP emissions (NESHAP subpart 
ZZZZ); existing and new manufacturers, owners, and operators of 
stationary CI internal combustion engines (NSPS subpart IIII); existing 
and new manufacturers, owners, and operators of stationary SI internal 
combustion engines (NSPS subpart JJJJ).
    Respondents' obligation to respond: Mandatory.
    Estimated number of respondents: 915,781 (ZZZZ); 207,360 (IIII); 
19,835 (JJJJ).
    Frequency of response: Varies by rule and by type of response.
    Total estimated burden: (61,799) (ZZZZ); (95,928) (IIII); (1,144) 
(JJJJ) hours (per year). Burden is defined at 5 CFR 1320.3(b). Note: 
parentheses indicate a reduction in burden, i.e., a reduced number of 
hours as a result of the addition of electronic reporting to the rules.
    Total estimated cost: ($7,581,151) (ZZZZ); ($11,688,145) (IIII); 
($140,379) (JJJJ) (per year), includes $0 annualized capital or 
operation & maintenance costs. Note: parentheses indicate a reduction 
in cost as a result of the addition of electronic reporting to the 
rules.
    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 numbers for the 
EPA's regulations in 40 CFR are listed in 40 CFR part 9. When OMB 
approves this ICR, the Agency will announce that approval in the 
Federal Register and publish a technical amendment to 40 CFR part 9 to 
display the OMB control number for the approved information collection 
activities contained in this final 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. The 
small entities subject to the requirements of this action are small 
businesses, small governmental jurisdictions and small non-profits 
across a range of sectors, that own or operate stationary engines 
(e.g., for generating electricity in remote areas or when electricity 
supply is temporarily interrupted), including but not limited to: 
Electric power generation, transmission, or distribution; Medical and 
surgical hospitals; Natural gas transmission; Crude petroleum and 
natural gas production; Natural gas liquids producers; and National 
security.
    The amendments to 40 CFR part 60, subparts IIII and JJJJ have 
estimated cost savings for respondents by reducing reporting burdens. 
We conducted analysis assessing the impacts of the costs associated 
with the amendments to 40 CFR part 63, subpart ZZZZ. As shown in the 
supporting statement to 40 CFR part 63, subpart ZZZZ, this subpart has 
estimated costs of $32 per respondent in 1 year, and cost savings in 
following years. We estimate that this compliance cost of $32 per 
respondent is well below a 1 percent impact relative to payroll or 
sales for affected small entities.\15\ While there is some uncertainty 
in these estimates, due to the range of entities that may own or 
operate stationary engines, there is a large margin before the impacts 
would approach a 1 percent impact for a substantial number of small 
entities. Details of this analysis are presented in the memorandum 
titled Economic Impact and Small Business Analysis for the National 
Emission Standards for Hazardous Air Pollutants: Reciprocating Internal 
Combustion Engines and New Source Performance Standards: Internal 
Combustion Engines; Electronic Reporting Amendment, which is available 
in the docket for this action.
---------------------------------------------------------------------------

    \15\ For example, for an entity with $32,000 in payroll, the 
compliance cost would represent an impact of 0.1% relative to 
payroll.
---------------------------------------------------------------------------

D. Unfunded Mandates Reform Act (UMRA)

    This action does not contain an unfunded mandate of $100 million or 
more as described in UMRA, 2 U.S.C. 1531-1538, and does not 
significantly or uniquely affect small governments. This action will 
reduce reporting costs for all sources, although we did estimate some 
initial costs (well under $100 million in the aggregate) for some 
sources.

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. While some Tribes could be impacted by this 
amendment, this rulemaking would reduce the compliance costs for owners 
and operators of stationary engines. Thus, Executive Order 13175 does 
not apply to this action.

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

    The EPA interprets Executive Order 13045 as applying only to those 
regulatory actions that concern environmental health or safety risks 
that the EPA has reason to believe may disproportionately affect 
children, per the definition of ``covered regulatory action'' in 
section 2-202 of the Executive Order.
    Therefore, this action is not subject to Executive Order 13045 
because it does not concern an environmental health risk or safety 
risk. Since this action does not concern human health, the EPA's Policy 
on Children's Health also does not apply.

[[Page 70512]]

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 and 
Executive Order 14096: Revitalizing Our Nation's Commitment to 
Environmental Justice for All

    The EPA believes that this type of action does not concern human 
health or environmental conditions and therefore cannot be evaluated 
with respect to potentially disproportionate and adverse effects on 
communities with environmental justice concerns. This is because this 
action involves the addition of electronic reporting and therefore is 
not expected to change emissions.

K. Congressional Review Act (CRA)

    This action is subject to the CRA, and the EPA will submit a rule 
report to each House of the Congress and to the Comptroller General of 
the United States. This action is not a ``major rule'' as defined by 5 
U.S.C. 804(2).

    The revisions and additions read as follows:


Sec.  60.4214  What are my notification, reporting, and recordkeeping 
requirements if I am an owner or operator of a stationary CI internal 
combustion engine?

    (a) * * *
    (1) Submit an initial notification as required in Sec.  60.7(a)(1). 
The notification must include the information in paragraphs (a)(1)(i) 
through (v) of this section. Beginning on February 26, 2025, submit the 
notification electronically according to paragraph (g) of this section.
* * * * *
    (d) * * *
    (3) The annual report must be submitted electronically using the 
subpart specific reporting form in the Compliance and Emissions Data 
Reporting Interface (CEDRI) that is accessed through EPA's Central Data 
Exchange (CDX) (https://cdx.epa.gov/). However, if the reporting form 
specific to this subpart is not available in CEDRI at the time that the 
report is due, the written report must be submitted to the 
Administrator at the appropriate address listed in Sec.  60.4. 
Beginning on February 26, 2025, submit annual report electronically 
according to paragraph (g) of this section.
* * * * *
    (f) Beginning on February 26, 2025, within 60 days after the date 
of completing each performance test required by this subpart, you must 
submit the results of the performance test required under this section 
following the procedures specified in paragraphs (f)(1) and (2) of this 
section.
    (1) Data collected using test methods supported by the EPA's 
Electronic Reporting Tool (ERT) as listed on the EPA's ERT website 
(https://www.epa.gov/electronic-reporting-air-emissions/electronic-reporting-tool-ert) at the time of the test. Submit the results of the 
performance test to the EPA via the Compliance and Emissions Data 
Reporting Interface (CEDRI), according to paragraph (g) of this 
section. The data must be submitted in a file format generated using 
the EPA's ERT. Alternatively, you may submit an electronic file 
consistent with the extensible markup language (XML) schema listed on 
the EPA's ERT website.
    (2) Data collected using test methods that are not supported by the 
EPA's ERT as listed on the EPA's ERT website at the time of the test. 
The results of the performance test must be included as an attachment 
in the ERT or an alternate electronic file consistent with the XML 
schema listed on the EPA's ERT website. Submit the ERT generated 
package or alternative file to the EPA via CEDRI according to paragraph 
(g) of this section.
    (g) If you are required to submit notifications or reports 
following the procedure specified in this paragraph (g), you must 
submit notifications or reports to the EPA via the Compliance and 
Emissions Data Reporting Interface (CEDRI), which can be accessed 
through the EPA's Central Data Exchange (CDX) (https://cdx.epa.gov/). 
The EPA will make all the information submitted through CEDRI available 
to the public without further notice to you. Do not use CEDRI to submit 
information you claim as CBI. Although we do not expect persons to 
assert a claim of CBI, if you wish to assert a CBI claim for some of 
the information in the report or notification, you must submit a 
complete file in the format specified in this subpart, including 
information claimed to be CBI, to the EPA following the procedures in 
paragraphs (g)(1) and (2) of this section. Clearly mark the part or all 
of the information that you claim to be CBI. Information not marked as 
CBI may be authorized for public release without prior notice. 
Information marked as CBI will not be disclosed except in accordance 
with procedures set forth in 40 CFR part 2. All CBI claims must be 
asserted at the time of submission. Anything submitted using CEDRI 
cannot later be claimed CBI. Furthermore, under CAA section 114(c), 
emissions data is not entitled to confidential treatment, and the EPA 
is required to make emissions data available to the public. Thus, 
emissions data will not be protected as CBI and will be made publicly 
available. You must submit the same file submitted to the CBI office 
with the CBI omitted to the EPA via the EPA's CDX as described earlier 
in this paragraph (g).
    (1) The preferred method to receive CBI is for it to be transmitted 
electronically using email attachments, File Transfer Protocol, or 
other online file sharing services. Electronic submissions must be 
transmitted directly to the OAQPS CBI Office at the email address 
[email protected], and as described in paragraph (g) of this section, 
should include clear CBI markings. ERT files should be flagged to

[[Page 70513]]

the attention of the Group Leader, Measurement Policy Group; all other 
files should be flagged to the attention of the Stationary Compression 
Ignition Internal Combustion Engine Sector Lead. If assistance is 
needed with submitting large electronic files that exceed the file size 
limit for email attachments, and if you do not have your own file 
sharing service, please email [email protected] to request a file 
transfer link.
    (2) If you cannot transmit the file electronically, you may send 
CBI information through the postal service to the following address: 
OAQPS Document Control Officer (C404-02), OAQPS, U.S. Environmental 
Protection Agency, 109 T.W. Alexander Drive, P.O. Box 12055, Research 
Triangle Park, North Carolina 27711. ERT files should be sent to the 
attention of the Group Leader, Measurement Policy Group, and all other 
files should be sent to the attention of the Stationary Compression 
Ignition Internal Combustion Engine Sector Lead. The mailed CBI 
material should be double wrapped and clearly marked. Any CBI markings 
should not show through the outer envelope.
    (h) If you are required to electronically submit a report through 
CEDRI in the EPA's CDX, you may assert a claim of EPA system outage for 
failure to timely comply with that reporting requirement. To assert a 
claim of EPA system outage, you must meet the requirements outlined in 
paragraphs (h)(1) through (7) of this section.
    (1) You must have been or will be precluded from accessing CEDRI 
and submitting a required report within the time prescribed due to an 
outage of either the EPA's CEDRI or CDX systems.
    (2) The outage must have occurred within the period of time 
beginning five business days prior to the date that the submission is 
due.
    (3) The outage may be planned or unplanned.
    (4) You must submit notification to the Administrator in writing as 
soon as possible following the date you first knew, or through due 
diligence should have known, that the event may cause or has caused a 
delay in reporting.
    (5) You must provide to the Administrator a written description 
identifying:
    (i) The date(s) and time(s) when CDX or CEDRI was accessed and the 
system was unavailable;
    (ii) A rationale for attributing the delay in reporting beyond the 
regulatory deadline to EPA system outage;
    (iii) A description of measures taken or to be taken to minimize 
the delay in reporting; and
    (iv) The date by which you propose to report, or if you have 
already met the reporting requirement at the time of the notification, 
the date you reported.
    (6) The decision to accept the claim of EPA system outage and allow 
an extension to the reporting deadline is solely within the discretion 
of the Administrator.
    (7) In any circumstance, the report must be submitted 
electronically as soon as possible after the outage is resolved.
    (i) If you are required to electronically submit a report through 
CEDRI in the EPA's CDX, you may assert a claim of force majeure for 
failure to timely comply with that reporting requirement. To assert a 
claim of force majeure, you must meet the requirements outlined in 
paragraphs (i)(1) through (5) of this section.
    (1) You may submit a claim if a force majeure event is about to 
occur, occurs, or has occurred or there are lingering effects from such 
an event within the period of time beginning five business days prior 
to the date the submission is due. For the purposes of this section, a 
force majeure event is defined as an event that will be or has been 
caused by circumstances beyond the control of the affected facility, 
its contractors, or any entity controlled by the affected facility that 
prevents you from complying with the requirement to submit a report 
electronically within the time period prescribed. Examples of such 
events are acts of nature (e.g., hurricanes, earthquakes, or floods), 
acts of war or terrorism, or equipment failure or safety hazard beyond 
the control of the affected facility (e.g., large scale power outage).
    (2) You must submit notification to the Administrator in writing as 
soon as possible following the date you first knew, or through due 
diligence should have known, that the event may cause or has caused a 
delay in reporting.
    (3) You must provide to the Administrator:
    (i) A written description of the force majeure event;
    (ii) A rationale for attributing the delay in reporting beyond the 
regulatory deadline to the force majeure event;
    (iii) A description of measures taken or to be taken to minimize 
the delay in reporting; and
    (iv) The date by which you propose to report, or if you have 
already met the reporting requirement at the time of the notification, 
the date you reported.
    (4) The decision to accept the claim of force majeure and allow an 
extension to the reporting deadline is solely within the discretion of 
the Administrator.
    (5) In any circumstance, the reporting must occur as soon as 
possible after the force majeure event occurs.
    (j) Any records required to be maintained by this subpart that are 
submitted electronically via the EPA's CEDRI may be maintained in 
electronic format. This ability to maintain electronic copies does not 
affect the requirement for facilities to make records, data, and 
reports available upon request to a delegated air agency or the EPA as 
part of an on-site compliance evaluation.

4. Amend Sec.  60.4245 by:
0
a. Revising paragraph (c) introductory text, paragraphs (d), and 
(e)(3); and
0
b. Adding paragraphs (f), (g), (h), (i), and (j).
    The revisions and additions read as follows:


Sec.  60.4245  What are my notification, reporting, and recordkeeping 
requirements if I am an owner or operator of a stationary SI internal 
combustion engine?

* * * * *
    (c) Owners and operators of stationary SI ICE greater than or equal 
to 500 HP that have not been certified by an engine manufacturer to 
meet the emission standards in Sec.  60.4231 must submit an initial 
notification as required in Sec.  60.7(a)(1). The notification must 
include the information in paragraphs (c)(1) through (5) of this 
section. Beginning on February 26, 2025 submit the notification 
electronically according to paragraph (g) of this section.
* * * * *
    (d) Owners and operators of stationary SI ICE that are subject to 
performance testing must submit a copy of each performance test as 
conducted in Sec.  60.4244 within 60 days after the test has been 
completed. Performance test reports using EPA Method 18, EPA Method 
320, or ASTM D6348-03 (incorporated by reference--see 40 CFR 60.17) to 
measure VOC require reporting of all QA/QC data. For Method 18, report 
results from sections 8.4 and 11.1.1.4; for Method 320, report results 
from sections 8.6.2, 9.0, and 13.0; and for ASTM D6348-03 report 
results of all QA/QC procedures in Annexes 1-7. Beginning on February 
26, 2025, performance tests must be reported electronically according 
to paragraph (f) of this section.
    (e) * * *
    (3) The annual report must be submitted electronically using the 
subpart specific reporting form in the Compliance and Emissions Data 
Reporting Interface (CEDRI) that is accessed through EPA's Central Data 
Exchange (CDX) (https://cdx.epa.gov/). However, if the reporting form 
specific to this subpart is not available in CEDRI at the time that the 
report is due, the written report must be submitted to the 
Administrator at the appropriate address listed in Sec.  60.4. 
Beginning on February 26, 2025, submit annual report electronically 
according to paragraph (g) of this section.
    (f) Beginning on February 26, 2025, within 60 days after the date 
of completing each performance test, you must submit the results 
following the procedures specified in paragraph (g) of this section. 
Data collected using test methods that are supported by the EPA's 
Electronic Reporting Tool (ERT) as listed on the EPA's ERT website 
(https://www.epa.gov/electronic-reporting-air-emissions/electronic-reporting-tool-ert) at the time of the test must be submitted in a file 
format generated using the EPA's ERT. Alternatively, you may submit an 
electronic file consistent with the extensible markup language (XML) 
schema listed on the EPA's ERT website. Data collected using test 
methods that are not supported by the EPA's ERT as listed on the EPA's 
ERT website at the time of the test must be included as an attachment 
in the ERT or an alternate electronic file.
    (g) If you are required to submit notifications or reports 
following the procedure specified in this paragraph (g), you must 
submit notifications or reports to the EPA via the Compliance and 
Emissions Data Reporting Interface (CEDRI), which can be accessed 
through the EPA's Central Data Exchange (CDX) (https://cdx.epa.gov/). 
The EPA will make all the information submitted through CEDRI available 
to the public without further notice to you. Do not use CEDRI to submit 
information you claim as CBI. Although we do not expect persons to 
assert a claim of CBI, if you wish to assert a CBI claim for some of 
the information in the report or notification, you must submit a 
complete file in the format specified in this subpart, including 
information claimed to be CBI, to the EPA following the procedures in 
paragraphs (g)(1) and (2) of this section. Clearly mark the part or all 
of the information that you claim to be CBI. Information not marked as 
CBI may be authorized for public release without prior notice. 
Information marked as CBI will not be disclosed except in accordance 
with procedures set forth in 40 CFR part 2. All CBI claims must be 
asserted at the time of submission. Anything submitted using CEDRI 
cannot later be claimed CBI. Furthermore, under CAA section 114(c), 
emissions data is not entitled to confidential treatment, and the EPA 
is required to make emissions data

[[Page 70515]]

available to the public. Thus, emissions data will not be protected as 
CBI and will be made publicly available. You must submit the same file 
submitted to the CBI office with the CBI omitted to the EPA via the 
EPA's CDX as described earlier in this paragraph (g).
    (1) The preferred method to receive CBI is for it to be transmitted 
electronically using email attachments, File Transfer Protocol, or 
other online file sharing services. Electronic submissions must be 
transmitted directly to the OAQPS CBI Office at the email address 
[email protected], and as described in paragraph (g) of this section, 
should include clear CBI markings. ERT files should be flagged to the 
attention of the Group Leader, Measurement Policy Group; all other 
files should be flagged to the attention of the Stationary Spark 
Ignition Internal Combustion Engine Sector Lead. If assistance is 
needed with submitting large electronic files that exceed the file size 
limit for email attachments, and if you do not have your own file 
sharing service, please email [email protected] to request a file 
transfer link.
    (2) If you cannot transmit the file electronically, you may send 
CBI information through the postal service to the following address: 
OAQPS Document Control Officer (C404-02), OAQPS, U.S. Environmental 
Protection Agency, 109 T.W. Alexander Drive, P.O. Box 12055, Research 
Triangle Park, North Carolina 27711. ERT files should be sent to the 
attention of the Group Leader, Measurement Policy Group, and all other 
files should be sent to the attention of the Stationary Spark Ignition 
Internal Combustion Engine Sector Lead. The mailed CBI material should 
be double wrapped and clearly marked. Any CBI markings should not show 
through the outer envelope.
    (h) If you are required to electronically submit a report through 
CEDRI in the EPA's CDX, you may assert a claim of EPA system outage for 
failure to timely comply with that reporting requirement. To assert a 
claim of EPA system outage, you must meet the requirements outlined in 
paragraphs (h)(1) through (7) of this section.
    (1) You must have been or will be precluded from accessing CEDRI 
and submitting a required report within the time prescribed due to an 
outage of either the EPA's CEDRI or CDX systems.
    (2) The outage must have occurred within the period of time 
beginning five business days prior to the date that the submission is 
due.
    (3) The outage may be planned or unplanned.
    (4) You must submit notification to the Administrator in writing as 
soon as possible following the date you first knew, or through due 
diligence should have known, that the event may cause or has caused a 
delay in reporting.
    (5) You must provide to the Administrator a written description 
identifying:
    (i) The date(s) and time(s) when CDX or CEDRI was accessed and the 
system was unavailable;
    (ii) A rationale for attributing the delay in reporting beyond the 
regulatory deadline to EPA system outage;
    (iii) A description of measures taken or to be taken to minimize 
the delay in reporting; and
    (iv) The date by which you propose to report, or if you have 
already met the reporting requirement at the time of the notification, 
the date you reported.
    (6) The decision to accept the claim of EPA system outage and allow 
an extension to the reporting deadline is solely within the discretion 
of the Administrator.
    (7) In any circumstance, the report must be submitted 
electronically as soon as possible after the outage is resolved.
    (i) If you are required to electronically submit a report through 
CEDRI in the EPA's CDX, you may assert a claim of force majeure for 
failure to timely comply with that reporting requirement. To assert a 
claim of force majeure, you must meet the requirements outlined in 
paragraphs (i)(1) through (5) of this section.
    (1) You may submit a claim if a force majeure event is about to 
occur, occurs, or has occurred or there are lingering effects from such 
an event within the period of time beginning five business days prior 
to the date the submission is due. For the purposes of this section, a 
force majeure event is defined as an event that will be or has been 
caused by circumstances beyond the control of the affected facility, 
its contractors, or any entity controlled by the affected facility that 
prevents you from complying with the requirement to submit a report 
electronically within the time period prescribed. Examples of such 
events are acts of nature (e.g., hurricanes, earthquakes, or floods), 
acts of war or terrorism, or equipment failure or safety hazard beyond 
the control of the affected facility (e.g., large scale power outage).
    (2) You must submit notification to the Administrator in writing as 
soon as possible following the date you first knew, or through due 
diligence should have known, that the event may cause or has caused a 
delay in reporting.
    (3) You must provide to the Administrator:
    (i) A written description of the force majeure event;
    (ii) A rationale for attributing the delay in reporting beyond the 
regulatory deadline to the force majeure event;
    (iii) A description of measures taken or to be taken to minimize 
the delay in reporting; and
    (iv) The date by which you propose to report, or if you have 
already met the reporting requirement at the time of the notification, 
the date you reported.
    (4) The decision to accept the claim of force majeure and allow an 
extension to the reporting deadline is solely within the discretion of 
the Administrator.
    (5) In any circumstance, the reporting must occur as soon as 
possible after the force majeure event occurs.
    (j) Any records required to be maintained by this subpart that are 
submitted electronically via the EPA's CEDRI may be maintained in 
electronic format. This ability to maintain electronic copies does not 
affect the requirement for facilities to make records, data, and 
reports available upon request to a delegated air agency or the EPA as 
part of an on-site compliance evaluation.

    (i) If you own or operate a stationary CI engine that is subject to 
the work, operation or management practices in items 1 or 2 of table 2c 
to this subpart or in items 1 or 4 of table 2d to this subpart, you 
have the option of utilizing an oil analysis program in order to extend 
the specified oil and filter change requirement in tables 2c and 2d to 
this subpart. The oil analysis must be performed at the same frequency 
specified for changing the oil and filter in table 2c or 2d to this 
subpart. The analysis program must at a minimum analyze the following 
three parameters: Total Base Number, viscosity, and percent water 
content. The condemning limits for these parameters are as follows: 
Total Base Number is less than 30 percent of the Total Base Number of 
the oil when new; viscosity of the oil has changed by more than 20 
percent from the viscosity of the oil when new; or percent water 
content (by volume) is greater than 0.5. If all of these condemning 
limits are not exceeded, the engine owner or operator is not required 
to change the oil and filter. If any of the limits are exceeded, the 
engine owner or operator must change the oil and filter within 2 
business days of receiving the results of the analysis; if the engine 
is not in operation when the results of the analysis are received, the 
engine owner or operator must change the oil and filter within 2 
business days or before commencing operation, whichever is later. The 
owner or operator must keep records of the parameters that are analyzed 
as part of the program, the results of the analysis, and the oil and 
filter changes for the engine. The analysis program must be part of the 
maintenance plan for the engine.
    (j) If you own or operate a stationary SI engine that is subject to 
the work, operation or management practices in items 6, 7, or 8 of 
table 2c to this subpart or in items 5, 6, 7, 8, 10, 11, or 13 of table 
2d to this subpart, you have the option of utilizing an oil analysis 
program in order to extend the specified oil and filter change 
requirement in tables 2c and 2d to this subpart. The oil analysis must 
be performed at the same frequency specified for changing the oil and 
filter in table 2c or 2d to this subpart. The analysis program must at 
a minimum analyze the following three parameters: Total Acid Number, 
viscosity, and percent water content. The condemning limits for these 
parameters are as follows: Total Acid Number increases by more than 3.0 
milligrams of potassium hydroxide (KOH) per gram from Total Acid Number 
of the oil when new; viscosity of the oil has changed by more than 20 
percent from the viscosity of the oil when new; or percent water 
content (by volume) is greater than 0.5. If all of these condemning 
limits are not exceeded, the engine owner or operator is not required 
to change the oil and filter. If any of the limits are exceeded, the 
engine owner or operator must change the oil and filter within 2 
business days of receiving the results of the analysis; if the engine 
is not in operation when the results of the analysis are received, the 
engine owner or operator must change the oil and filter within 2 
business days or before commencing operation, whichever is later. The 
owner or operator must keep records of the parameters that are analyzed 
as part of the program, the results of the analysis, and the oil and 
filter changes for the engine. The analysis program must be part of the 
maintenance plan for the engine.

    (2) Before February 26, 2025, for each initial compliance 
demonstration required in table 5 to this subpart that includes a 
performance test conducted according to the requirements in table 3 to 
this subpart, you must submit the Notification of Compliance Status, 
including the performance test results, before the close of business on 
the 60th day following the completion of the performance test according 
to Sec.  63.10(d)(2). Beginning on February 26, 2025, for each initial 
compliance demonstration required in table 5 to this subpart that 
includes a performance test conducted according to the requirements in 
table 3 to this subpart, you must submit the Notification of Compliance 
Status, including a summary of the performance test results, in PDF to 
the EPA via the Compliance and Emissions Data Reporting Interface 
(CEDRI), before the close of business on the 60th day following the 
completion of the performance test following the procedure specified in 
Sec.  63.9(k), except any Confidential Business Information (CBI) is to 
be submitted according to paragraphs (h)(2)(i) and (ii) of this 
section. Do not use CEDRI to submit information you claim as CBI. 
Although we do not expect persons to assert a claim of CBI, if you wish 
to assert a CBI claim for some of the information in the report, you 
must submit a complete file, including information claimed to be CBI, 
to the EPA following the procedures in paragraphs (h)(2)(i) and (ii) of 
this section. Clearly mark the part or all of the information that you 
claim to be CBI. Information not marked as CBI may be authorized for 
public release without prior notice. Information marked as CBI will not 
be disclosed except in accordance with procedures set forth in 40 CFR 
part 2. All CBI claims must be asserted at the time of submission. 
Anything submitted using CEDRI cannot later be claimed CBI. 
Furthermore, under CAA section 114(c), emissions data is not entitled 
to confidential treatment, and the EPA is required to make emissions 
data available to the public. Thus, emissions data will not be 
protected as CBI and will be made publicly available. You must submit 
the same file submitted to the CBI office with the CBI omitted to the 
EPA via the EPA's CDX as described earlier in this paragraph (h)(2).
    (i) The preferred method to receive CBI is for it to be transmitted 
electronically using email attachments, File Transfer Protocol, or 
other online file sharing services. Electronic submissions must be 
transmitted directly to the OAQPS CBI Office at the email address 
[email protected], and as described in paragraph (h)(2) of this section, 
should include clear CBI markings and be flagged to the attention of 
the Reciprocating Internal Combustion Engine Sector Lead. If assistance 
is needed with submitting large electronic files that exceed the file 
size limit for email attachments, and if you do not have your own file 
sharing service, please email [email protected] to request a file 
transfer link.
    (ii) If you cannot transmit the file electronically, you may send 
CBI information through the postal service to the following address: 
OAQPS Document Control Officer (C404-02), OAQPS, U.S. Environmental 
Protection Agency, 109 T.W. Alexander Drive, P.O. Box 12055, Research 
Triangle Park, North Carolina 27711, Attention Reciprocating Internal 
Combustion Engine Sector Lead. The mailed CBI material should be double

\1\ Sources have the option to utilize an oil analysis program as
  described in Sec.   63.6625(i) or (j) in order to extend the specified
  oil change requirement in table 2d of this subpart.
\2\ If an emergency engine is operating during an emergency and it is
  not possible to shut down the engine in order to perform the
  management practice requirements on the schedule required in table 2d
  of this subpart, or if performing the management practice on the
  required schedule would otherwise pose an unacceptable risk under
  Federal, state, or local law, the management practice can be delayed
  until the emergency is over or the unacceptable risk under Federal,
  state, or local law has abated. The management practice should be
  performed as soon as practicable after the emergency has ended or the
  unacceptable risk under Federal, state, or local law has abated.
  Sources must report any failure to perform the management practice on
  the schedule required and the Federal, state or local law under which
  the risk was deemed unacceptable.
