Revisions to Appendix P to 40 CFR Part 51, Concerning Minimum 
Emission Reporting Requirements in SIPs

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing to 
update a

[[Page 10122]]

regulation, Appendix P to 40 CFR part 51 (Appendix P), that specifies 
what State Implementation Plans (SIPs) must require of sources among 
four categories with respect to continuous emission monitoring, 
recording, and reporting. Those four Appendix P source categories are: 
Fossil fuel-fired steam generators; fluid bed catalytic cracking unit 
catalyst regenerators at petroleum refineries; sulfuric acid plants; 
and nitric acid plants. In particular, proposed amendments to Appendix 
P would revise the minimum frequency for submitting reports of excess 
emissions from ``each calendar quarter'' to ``twice per year at 6-month 
intervals.'' As a result, states may, in their SIPs, establish a 
semiannual reporting frequency for excess emissions at affected sources 
that aligns with what the EPA has generally established as the 
reporting frequency applicable to the Appendix P source categories 
under more recently updated regulations, such as New Source Performance 
Standards (NSPS) under 40 CFR part 60. Proposed amendments also include 
correction of an erroneous cross-reference in Appendix P.

SUPPLEMENTARY INFORMATION:

I. General Information

A. Does this action apply to me?

    Entities potentially affected directly by this action include 
states, United States (U.S.) territories, local authorities and 
eligible tribes that are currently administering, or may in the future 
administer, EPA-approved implementation plans (collectively 
``states'').\1\ Entities potentially affected indirectly by this action 
are sources categorized as fossil fuel-fired steam generators, fluid 
bed catalytic cracking unit catalyst regenerators at petroleum 
refineries, sulfuric acid plants, or nitric acid plants. For 
convenience, the EPA's reference to ``affected sources'' in this 
rulemaking generally refers to sources affected by SIP requirements, 
i.e., those sources to which a SIP's Appendix P-specified monitoring 
requirements actually apply. While all sources among the Appendix P 
source categories (when not already excepted in Appendix P itself) are 
potentially affected by such requirements, it is within the state's 
discretion to grant an exemption in its SIP from applicability of the 
Appendix P-specified monitoring requirements for certain sources. If 
you have questions regarding the applicability of this action to a 
particular entity, consult the person listed in the FOR FURTHER 
INFORMATION CONTACT section of this document.
---------------------------------------------------------------------------

    \1\ The EPA respects the unique relationship between the U.S. 
government and tribal authorities and acknowledges that tribal 
concerns are not interchangeable with state concerns. Under the CAA 
and EPA regulations, a tribe may, but is not required to, apply for 
eligibility to have a tribal implementation plan (TIP). For 
convenience, the EPA refers to either ``states'' or ``air agencies'' 
in this rulemaking when meaning to refer in general to states, the 
District of Columbia, U.S. territories, local air permitting 
authorities and eligible tribes that are currently administering, or 
may in the future administer, EPA-approved implementation plans.

II. Overview of Proposed Action

A. What action is the Agency proposing?

    The EPA is proposing amendments to update the data reporting 
requirements specified for SIPs under Appendix P to 40 CFR part 51. 
Appendix P, which the EPA promulgated in 1975, sets forth certain 
minimum requirements for continuous emission monitoring that each SIP 
must include in order to be approved under the provisions of 40 CFR 
51.214. See 40 FR 46240 (October 6, 1975).
    The EPA proposes to revise the current specification that sources 
among the four Appendix P source categories must report excess 
emissions at a frequency of no less than every calendar quarter, by 
changing the minimum frequency to semiannually. For example, the 
reference to ``each calendar quarter'' in paragraph 4.1 of Appendix P 
would be removed and replaced with a reference to ``twice per year at 
6-month intervals.'' As a result, states would be allowed to establish, 
in their SIPs, a reporting frequency for affected sources under 
Appendix P that aligns with the reporting frequency that the EPA has 
generally established under more recently updated programs applicable 
to sources among the four Appendix P source categories, such as NSPS. 
As described in Section III.B of this document, the EPA has generally 
moved to a semiannual reporting frequency specification for sources 
regulated under its regulations pursuant to the Clean Air Act (CAA), 
e.g., in NSPS (40 CFR part 60) and National Emission Standards for 
Hazardous Air Pollutants (NESHAP) (40 CFR parts 61 and 63).\2\ A 
semiannual minimum reporting frequency under Appendix P would also 
align with the semiannual reporting frequency required of sources 
through the EPA's regulations for title V operating permits (40 CFR 
parts 70 and 71).\3\ Notwithstanding these proposed revisions to 
Appendix P, a source that is subject to other excess emission reporting 
requirements (e.g., under 40 CFR parts 60, 61, or 63) would be required 
to comply with the applicable provisions of those rules.
---------------------------------------------------------------------------

    \2\ ``Recordkeeping and Reporting Burden Reduction, Final 
amendments,'' 64 FR 7457 (February 12, 1999).
    \3\ The title V permit shall require submittal of reports of any 
required monitoring at least every 6 months, and all instances of 
deviations from permit requirements must be clearly identified in 
such reports. See 40 CFR 70.6(a)(3)(iii)(A) and 40 CFR 
71.6(a)(3)(iii)(A).
---------------------------------------------------------------------------

    The EPA emphasizes that the proposed amendments to Appendix P, if 
finalized as proposed, would not require states to adopt these 
particular changes (by revising their SIPs). When proposing in 1974 to 
add Appendix P to 40 CFR part 51, the EPA stressed that Appendix P set 
forth only minimum requirements and recognized that in keeping with the 
basic framework of SIPs, states were allowed, even encouraged, to 
develop procedures even more comprehensive than those in Appendix P.\4\ 
Likewise, upon promulgating Appendix P in 1975, the EPA stated that 
while minimum requirements were being established, states ``may, as 
they deem appropriate, expand these requirements.'' \5\ Thus, although 
the relaxation in minimum reporting frequency specified for SIPs under 
Appendix P being proposed would allow a state in turn to require 
semiannual reporting of sources among the Appendix P source categories, 
it would not obligate a state to adopt requirements for semiannual 
reporting in its SIP if the state chooses to retain requirements beyond 
the minimum (e.g., quarterly reporting requirements for Appendix P 
source categories).

Submittal of Implementation Plans: Emission Monitoring of Stationary 
Sources,'' 40 FR 46240 (October 6, 1975). See 46246/3.
---------------------------------------------------------------------------

    An additional amendment proposed in this action would revise one 
cross-reference under Appendix P so that it refers to the appropriate 
section of 40 CFR part 51. In accordance with the EPA's regulations for 
SIPs concerning continuous emission monitoring, each SIP must meet 
certain minimum requirements, including those specified in Appendix P. 
The continuous

[[Page 10124]]

emission monitoring regulations of 40 CFR part 51 were moved from Sec.  
51.19(e) to Sec.  51.214 as part of a 1986 rule through which the EPA 
significantly restructured and consolidated its regulations for the 
development of SIPs.\6\ In the notice of final rulemaking for that 1986 
rule, several cross-references under Appendix P were revised. The EPA 
acknowledges that the cross-reference in Appendix P under section 1.0 
(which concerns contininuous emission monitoring requirements) was 
changed from Sec.  51.19(e) to Sec.  51.165(b) in error, when the 
intent was to change it to Sec.  51.214. The EPA now proposes to revise 
section 1.0 of Appendix P so that it correctly refers to the continuous 
emission monitoring regulations at Sec.  51.214.

B. What is the Agency's authority for proposing this action?

    This document is being developed under the authority of sections 
110(a)(2)(F) and 301(a) of the CAA.

III. Historical and Regulatory Background for Appendix P

A. State Implementation Plans and the EPA's Regulations at 40 CFR Part 
51

    The SIP is a state's plan identifying how the state will meet its 
CAA requirements, such as to attain and maintain the National Ambient 
Air Quality Standards (NAAQS). Pursuant to section 110 of the CAA, each 
state is required to submit a SIP for EPA approval, and the EPA is 
required to evaluate and either approve or disapprove the state's 
submission. The SIP (including revisions over time) contains control 
measures and strategies developed through a public process and formally 
adopted by the state. The elements of a SIP are prescribed in 
particular under section 110 and Part D of the CAA. Of particular 
relevance to this proposed rulemaking, CAA section 110(a)(2)(F) governs 
requirements associated with stationary source monitoring and reporting 
in the context of SIPs.
    Pursuant to CAA section 110, the EPA established procedural 
requirements applicable to all states concerning the preparation, 
adoption, and submission of SIPs and SIP revisions. These regulations, 
initially promulgated in 1971, comprise 40 CFR part 51, ``Requirements 
for Preparation, Adoption, and Submittal of Implementation Plans.'' 
Like the SIPs themselves, these regulations are periodically revised.

B. Part 51 Amended To Require Continuous Emission Monitoring

    The EPA in 1974 proposed to amend its SIP preparation regulations 
under 40 CFR part 51 to require that SIPs contain legally enforceable 
procedures mandating owners or operators of stationary sources to 
install equipment to monitor pollutant emissions on a continuous basis 
and to report the data obtained.\7\ As was explained in the 1974 notice 
of proposed rulemaking, the regulations already required states to have 
the legal authority to require such monitoring and recording.\8\ 
However, at the time that the EPA's SIP preparation regulations were 
originally published, ``[t]he Agency believed that the state-of-the-art 
was such that it was not prudent to require existing sources to install 
[continuous monitoring] devices.'' \9\ The agency explained that, for 
certain sources, ``general specifications for accuracy, reliability and 
durability can be established for continuous emission monitors . . . 
.'' \10\ Accordingly, the agency proposed to amend 40 CFR part 51 by 
adding a new requirement that would ``require States to revise their 
implementation plans to require sources to install monitoring 
instruments and to report the resulting data to the appropriate State 
Agency.'' \11\

    In choosing the types of sources and pollutants listed in Appendix 
P and, thus, subject to the proposed minimum requirements for 
continuous emission monitoring specified for SIPs, the EPA selected 
four source categories that would be covered by continuous emission 
monitoring requirements and performance testing methods simultaneously 
proposed under NSPS regulations pursuant to section 111 of the CAA 
(i.e., under Part 60).\12\ The EPA even noted in the Appendix P 
proposal that the SIP rulemaking was very closely connected with the 
NSPS rulemaking. The EPA urged states and other affected parties to 
consider the companion NSPS proposal as part of the Appendix P proposal 
and to direct comments to the relevant portions of both proposals.\13\

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

    In 1975, the EPA promulgated Appendix P on the same day it 
promulgated the NSPS monitoring and performance requirements under 40 
CFR part 60.\14\ In the final amendments to 40 CFR part 51, the EPA 
expanded 40 CFR 51.19 (now 40 CFR 51.214) to require states to revise 
their SIPs to include legally enforceable procedures requiring certain 
specified categories of existing stationary sources to monitor 
emissions on a continuous basis. The agency explained that requiring 
``a sound program of continuous emission monitoring and reporting'' 
would more fully implement CAA sections 110(a)(2)(F)(ii) and (iii).\15\

Sources,'' 40 FR 46240 (October 6, 1975).
---------------------------------------------------------------------------

    Section 51.19(e)(4) (now Sec.  51.214(e)) in 40 CFR specifies such 
procedures to require the source owner or operator to submit 
information relating to emissions and operation of the emission 
monitors to the state to the extent described in Appendix P as 
frequently as or more frequently than described therein.\16\ With 
respect to reporting requirements, Appendix P specifies under paragraph 
4.1 that the SIP ``shall require owners or operators of facilities 
required to install continuous monitoring systems to submit a written 
report of excess emissions for each calendar quarter and the nature and 
cause of the excess emissions, if known.'' \17\ At the time of 
promulgation in 1975, this specification in Appendix P of quarterly 
reporting as the minimum frequency was by design aligned with the 
quarterly reporting frequency generally specified for new sources under 
Part 60. This ``report of excess emissions,'' like the corollary 
``excess emissions and monitoring systems performance report'' 
specified under 40 CFR part 60 (see Sec.  60.7(c)), should be submitted 
by the owner or operator whether or not excess emissions occurred 
within the reporting period (see Appendix P, paragraph 4.5).

    Each state is required to include all of the Appendix P-specified 
requirements in its SIP, including the monitoring requirements listed 
in Appendix P under section 1.1, ``Applicability,'' for sources 
specified under Appendix P at a minimum.\18\ However, section 1.2, 
``Exemptions,'' provides that a state may exempt certain sources from 
applicability of those monitoring requirements. When proposing in 1974 
to amend the 40 CFR part 51 regulations

[[Page 10125]]

to include minimum requirements for continuous emission monitoring, the 
EPA noted that the 40 CFR part 51 amendments were not intended to 
necessarily apply to new sources, since the 40 CFR part 60 (NSPS) 
requirements would apply to those new sources.\19\ Therefore, in 
accordance with Appendix P, paragraph 1.2.1, a state may choose to 
include in its SIP a provision to grant an exemption from the Appendix 
P-specified monitoring requirements for a source that is subject to an 
NSPS promulgated in 40 CFR part 60. Similarly, in accordance with 
paragraph 1.2.2, a state may choose to include in its SIP a provision 
to grant an exemption for a source that is not subject to an applicable 
emission standard of the approved SIP. As the EPA clarified in the 40 
CFR part 51 amendments, Appendix P-specified continuous emission 
monitors ``are not required for sources unless such sources are subject 
to an applicable emission limitation of an approved SIP.'' \20\ In 
addition, in accordance with paragraph 1.2.3, a state was allowed to 
include in its SIP a provision granting an exemption for certain 
affected sources that were scheduled for retirement within 5 years 
after inclusion of the Appendix P monitoring requirements in its SIP.

IV. Rationale for Updating Appendix P

A. Proposed Action Comports With the EPA's Burden Reduction Rule of 
1999

    As of 1975, when the continuous emission monitoring specifications 
for SIPs under 40 CFR part 51 and for NSPS under 40 CFR part 60 were 
promulgated, sources affected under either set of regulations were 
required to submit continuous emission monitor reports of their excess 
emissions and other information on a quarterly basis. Over the next 
many years, the EPA expanded the types of sources to be regulated 
pursuant to CAA sections 111 (for NSPS) and 112 (for NESHAP), and those 
later regulations (e.g., NSPS under 40 CFR part 60 and NESHAP under 40 
CFR parts 61 and 63) increasingly allowed sources to submit such 
reports on a less frequent basis, semiannually or in some cases even 
annually. In the agency's experience, semiannual reporting provides 
sufficiently timely information to ensure compliance and enable 
adequate enforcement of applicable requirements, while imposing less 
burden on the affected industry than would quarterly reporting. Thus, 
in 1999, the EPA promulgated a Burden Reduction Rule,\21\ which, among 
other revisions, revised the NSPS reporting frequency, with a few 
exceptions,\22\ to semiannually for nearly all source categories. As a 
result, the reporting frequency requirements under NSPS regulations, 
including for the four Appendix P source categories, no longer aligned 
with the reporting requirements specified in Appendix P.
---------------------------------------------------------------------------

    \21\ ``Recordkeeping and Reporting Burden Reduction, Final 
amendments,'' 64 FR 7457 (February 12, 1999).
    \22\ For most source categories, the reporting requirements 
under NSPS and NESHAP General Provisions apply. However, a minority 
of the NSPS regulations do not adopt by reference the Part 60 
General Provisions for reporting requirements, instead explicitly 
specifying requirements for the affected source category. Certain 
reporting requirements, for particular pollutants and particular 
source categories, were not revised in the Burden Reduction Rule. 
For example, for those electric utility steam generating units 
subject to NSPS subpart Da (which also fall under Appendix P's 
``fossil fuel-fired steam generators'' source category), the 
regulation continues even today to require that opacity levels in 
excess of the applicable opacity standard and the date of such 
excesses are to be submitted (reported) to the Administrator each 
calendar quarter; see 40 CFR 60.51Da(i).
---------------------------------------------------------------------------

    As rationale for the Burden Reduction Rule, the EPA noted at 
proposal that its most recent NSPS and NESHAP had moved almost 
exclusively to semiannual reporting as a standard approach.\23\ Thus, 
also in the General Provisions for 40 CFR parts 60, 61, and 63, the 
Burden Reduction Rule changed the reporting frequency requirements, to 
conform them to recently promulgated NSPS and NESHAP regulations. The 
EPA estimated a 20-percent reduction in reporting burden on sources 
under a typical rule.\24\

revisions to rules and notice of public hearing,'' 61 FR 47840 
(September 11, 1996). See 61 FR 47844/2.
    \24\ Id.
---------------------------------------------------------------------------

    As noted by the EPA in the Burden Reduction Rule,\25\ and as 
recognized in Section II.A of this document, the EPA's regulations for 
title V operating permits also specify semiannual reporting by 
sources.\26\
---------------------------------------------------------------------------

    \25\ 64 FR 7457 at 7458/3.
    \26\ The title V permit shall require submittal of reports of 
any required monitoring at least every 6 months, and all instances 
of deviations from permit requirements must be clearly identified in 
such reports. See 40 CFR 70.6(a)(3)(iii)(A) and 40 CFR 
71.6(a)(3)(iii)(A).
---------------------------------------------------------------------------

B. States Urge the EPA To Reduce Reporting Frequency for Appendix P 
Source Categories

    With this proposed rulemaking, the EPA is seeking to reasonably 
resolve a longstanding inconsistency in its reporting requirements for 
certain categories of sources between (i) those specified as the 
minimum for Appendix P source categories in the SIP context (under 40 
CFR part 51) and (ii) those prescribed for similar sources through NSPS 
(under part 60) or NESHAP (under 40 CFR parts 61 and 63). The EPA 
acknowledges that two states in particular, South Carolina and 
Tennessee, have been urging the EPA to amend the Appendix P 
specification for reporting frequency. South Carolina and Tennessee 
each have sources among the Appendix P source categories that cannot be 
exempted from the Appendix P-specified monitoring requirements under 
any of the exemptions available under Appendix P section 1.2 
(Exemptions). While such sources are subject to SIP emission 
limitations, they are not subject to any NSPS because they commenced 
operation before the applicability dates of those standards. States 
have argued that the rationale on which the EPA has relied to decrease 
the minimum reporting frequency over time for sources regulated under 
NSPS, for example, is the same rationale on which the EPA should rely 
to decrease the minimum reporting frequency that Appendix P specifies 
for 40 CFR part 51 sources. Materials submitted by South Carolina and 
Tennessee, including their general arguments in support of--and in 
advance of--such action, are available in the docket for this 
rulemaking. The EPA is including those materials in the docket because 
they serve to illustrate how the proposed amendments to Appendix P 
might manifest in a SIP.

V. Environmental Justice Considerations

    A change in the specified minimum frequency with which affected 
sources must submit continuous monitoring system data reports, as a 
result of the proposed revisions to Appendix P, is not expected to 
result in any change in the pollutant emissions from any of the 
affected sources. Therefore, the EPA believes that this action will not 
have potential disproportionately high and adverse human health or 
environmental effects on minority, low-income, or indigenous 
populations.

VI. Statutory and Executive Order Reviews

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.

[[Page 10126]]

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)

    The information collection activities in this proposed rule have 
been submitted for approval to the OMB under the PRA. The ICR document 
that the EPA prepared has been assigned EPA ICR number 2590.01. You can 
find a copy of the ICR in the docket for this proposed rule, and it is 
briefly summarized here.
    The EPA is proposing to update a regulation, Appendix P to 40 CFR 
part 51, that specifies what SIPs must require of sources among four 
categories with respect to continuous emission monitoring, recording, 
and reporting. In particular, the proposed amendments to Appendix P 
would generally relax a ``minimum reporting frequency'' specification 
for SIPs from quarterly to semiannually. The subject rule would revise 
only the minimum requirement, and so the rule does not require that any 
state change the actual reporting frequency requirement in its SIP that 
applies to Appendix P sources. Therefore, to comply with the subject 
rule's requirements, each state may choose to prepare and submit a SIP 
revision but is not required to do so, and so the information 
collection activities in this proposed rule are voluntary for the 
states as respondents. The EPA has determined that the requested 
information collection (SIP submissions) would not include any 
confidential information. In accordance with 40 CFR 51.116, ``Data 
availability,'' each state must retain and make available for public 
inspection all detailed data and calculations used in the preparation 
of its SIP and SIP revisions. The EPA has the responsibility and 
statutory authority under CAA section 110(a) to assure that the states, 
through their SIPs, meet the requirements of the CAA. The regulatory 
burden under the information collection is attributed to states' 
preparation and submission of SIP revisions, a type of reporting 
burden. For purposes of estimating the paperwork burden, the EPA 
assumes that each of 56 entities, including states, the District of 
Columbia, and U.S. territories, would make a single SIP submission that 
includes an Appendix P-related provision within 3 years after the 
effective date of the rule, corresponding to the requested 3-year 
collection period. There are no capital costs or operation and 
maintenance costs attributed to the proposed rule.
    Respondents/affected entities: All states.
    Respondent's obligation to respond: Voluntary.
    Estimated number of respondents: 56.
    Frequency of response: One-time.
    Total estimated burden: 3,080 hours per year (or 55 hours per 
respondent per year). Burden is defined at 5 CFR 1320.3(b).
    Total estimated cost: $191,200 per year (or $3,414 per respondent 
per year), with no capital cost and no operation and maintenance cost.
    The derivation of these estimates is described in greater detail in 
the Supporting Statement for the initial, rule-related ICR for 
``Revisions to Appendix P to 40 CFR part 51'' that is included in the 
docket for this rulemaking.
    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.
    Submit your comments on the agency's need for this information, the 
accuracy of the provided burden estimates and any suggested methods for 
minimizing respondent burden to the EPA using the docket identified at 
the beginning of this rule. You may also send your ICR-related comments 
to OMB's Office of Information and Regulatory Affairs via email to 
[email protected], Attention: Desk Officer for the EPA. Since 
OMB is required to make a decision concerning the ICR between 30 and 60 
days after receipt, OMB must receive comments no later than March 23, 
2020. The EPA will respond to any ICR-related comments in the final 
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. Any 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 this rule. This action will not impose any 
requirements on small entities. Instead, this action leaves to each 
state the choice as to whether to reflect in its SIP a reduction in 
minimum reporting frequency specified for certain categories of 
stationary sources regulated under the CAA.

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, on the relationship between 
the national government and the states, or on 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 would not have a substantial direct effect on 
one or more Indian tribes, since no tribe has to develop a TIP under 
these regulatory revisions. Furthermore, these regulation revisions do 
not affect the relationship or distribution of power and 
responsibilities between the federal government and Indian tribes. The 
CAA and the Tribal Air Rule establish the relationship of the federal 
government and tribes in developing plans to attain the NAAQS, and 
these revisions to the regulations do nothing to modify that 
relationship. Thus, Executive Order 13175 does not apply to this 
action.

H. 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. This action is not subject to 
Executive Order 13045 because the reduction in minimum reporting 
frequency specified for certain categories of sources regulated under 
the CAA will have no effect on any obligation to comply with emission 
limitations in SIPs, and so it does not concern an environmental health 
risk or safety risk.

[[Page 10127]]

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

    This action is not a ``significant energy action'' because it is 
not likely to have a significant adverse effect on the supply, 
distribution or use of energy. This action merely allows states the 
option to reflect in their SIPs a reduction in minimum reporting 
frequency specified for certain categories of stationary sources 
regulated under the CAA.

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 populations as 
specified in Executive Order 12898 (59 FR 7629, February 16, 1994).
    This action merely allows states the option to reflect in their 
SIPs a reduction in minimum reporting frequency specified for certain 
categories of stationary sources regulated under the CAA, which will 
have no effect on any obligation to comply with emission limitations in 
SIPs.
