Prevention of Significant Deterioration (PSD) and Nonattainment
New Source Review (NSR): Reconsideration of Inclusion of Fugitive
Emissions; Interim Rule; Stay and Revisions

AGENCY: Environmental Protection Agency (EPA).

ACTION: Interim rule; stay and revisions.

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

SUMMARY: EPA is taking an interim action to effectuate and extend a
stay of the final rule entitled ``Prevention of Significant
Deterioration (PSD) and Nonattainment New Source Review (NSR):
Reconsideration of Inclusion of Fugitive Emissions'' (``Fugitive
Emissions Rule'') published in the Federal Register on December 19,
2008. The Fugitive Emissions Rule under the Federal NSR program
required that fugitive emissions be included in determining whether a
physical or operational change results in a major modification only for
sources in designated industries. EPA issued a stay of the Fugitive
Emissions Rule on March 31, 2010, that was effective for 18 months
through October 3, 2011. This action supersedes the stay and thereby
corrects potential confusion caused by that stay. To effectuate a stay
of the Fugitive Emissions Rule, this action clarifies the stay and the
revisions of specific paragraphs in the NSR regulations that were
affected by the Fugitive Emissions Rule. This action also extends the
stay until EPA completes its reconsideration of the Fugitive Emissions
Rule.

DATES: Effective date: This interim rule is effective March 30, 2011.
    The administrative stay of provisions in 40 CFR 51.165, 51.166,
Appendix S to part 51, and 40 CFR 52.21 published on March 31, 2010 (75
FR 16012) is lifted; and
    The following Code of Federal Regulations sections are stayed
indefinitely: 40 CFR 51.165(a)(1)(v)(G) and (a)(1)(vi)(C)(3);
51.166(b)(2)(v) and (b)(3)(iii)(d); Appendix S to Part 51, Paragraph
II.A.5(vii); and 52.21(b)(2)(v) and (b)(3)(iii)(c). The EPA will
publish a document in the Federal Register lifting this stay.
    Comment date: Comments must be received on or before April 29,
2011.

II. Background Information

    On December 19, 2008, EPA (``we'') issued a final rule revising the
requirements of the major NSR programs regarding the treatment of
fugitive emissions (``Fugitive Emissions Rule'') 73 FR 77882. The final
rule required fugitive emissions to be included in determining whether
a physical or operational change results in a major modification only
for sources in industries that have been designated through rulemaking
under section 302(j) of the Clean Air Act (Act or CAA). Previously, EPA
rules required that fugitive emissions be included in major
modification applicability determinations for all source categories.
The final rule amended all portions of the major NSR program
regulations: Permit requirements, the PSD program, and the emission
offset interpretive ruling.
    On February 17, 2009, the Natural Resources Defense Council (NRDC)
submitted a petition for reconsideration of the December 2008 final
rule as provided for in CAA 307(d)(7)(B).\1\
---------------------------------------------------------------------------

    \1\ John Walke, NRDC, EPA-HQ-OAR-2004-0014-0060.
---------------------------------------------------------------------------

    On April 24, 2009, we responded to the February 17, 2009, petition
by letter indicating that we were convening a reconsideration
proceeding for the December 2008 rule on inclusion of fugitive
emissions challenged in the petition and granting a 3-month
administrative stay of the rule contained in the federal NSR program at
40 CFR parts 51 and 52. The letter also indicated that we would publish
a notice of proposed rulemaking ``in the near future'' to address the
specific issues for which we were granting reconsideration.\2\
---------------------------------------------------------------------------

    \2\ Lisa Jackson, US EPA, EPA-HQ-OAR-2004-0014-0062.
---------------------------------------------------------------------------

    The initial 3-month administrative stay of the Fugitive Emissions
Rule became effective on September 30, 2009. See 74 FR 50115. An
interim final rule extending the stay for an additional 3 months became
effective on December 31, 2009. See 74 FR 65692. An additional 18 month
stay was finalized on March 31, 2010, and ends on October 3, 2011. See
75 FR 16012. That stay was put in place to allow sufficient time for
EPA to propose, take public comment on, and issue a final action
concerning the inclusion of fugitive emissions in the Federal NSR
program.

III. This Action

A. Why is EPA staying, reinstating, or revising, as appropriate, the
regulatory text in specific paragraphs affected by the Fugitive
Emissions Rule?

    The initial stay of the Fugitive Emissions Rule, put in place on
September 30, 2009, may have caused confusion as to the scope of the
stay. In staying the Fugitive Emissions Rule, EPA reinstated the NSR
regulations as they existed prior to the Fugitive Emissions Rule. In
particular, we stated: ``To effectuate this stay of the December 19,
2008, rule, we are reinstating previous provisions on a temporary
basis.'' See 74 FR at 50115-16. In several cases, however, paragraphs
of the affected regulations in 40 CFR 51.165, 40 CFR 51.166, 40 CFR 51
Appendix S, and 40 CFR 52.21 appeared to be stayed in their entirety
rather than amended to undo the changes made by the Fugitive Emissions
Rule as intended. The subsequent extensions of the stay used the same
terms as the stay published on September 30, 2009, and accordingly did
not correct the ambiguity created by the original promulgation of the
stay. This action clarifies the regulations to accurately reflect EPA's
intent to revert back to the regulation text that existed prior to the
Fugitive Emissions Rule amendments to the Federal NSR regulations.

B. Why is EPA issuing an interim rule?

    We are issuing an interim rule to effectuate a stay of the Fugitive
Emissions Rule. This interim rule supersedes the stay issued on March
31, 2010, and thereby corrects ambiguity contained in that stay. EPA is
using the ``good cause'' exemption under the Administrative Procedure
Act (APA) to take the actions set forth in this interim rule without
prior notice and comment. See 5 U.S.C. 553(b)(3)(B). Section 553(b)

of the APA generally requires that any rule to which it applies be
issued only after the public has received notice of, and had an
opportunity to comment on, the proposed rule. However, section
553(b)(3)(B) exempts from those requirements any rule for which the
issuing agency for good cause finds that providing prior notice and
comment would be impracticable, unnecessary, or contrary to the public
interest. Thus, any rule for which EPA makes such a finding is exempt
from the notice and comment requirements of section 553(b).
    We believe that the circumstances here provide good cause to take
the actions set forth in this interim rule without prior notice and
comment, because providing prior notice and comment would be
unnecessary and contrary to the public interest.
    With this action, EPA is simply staying the provisions of the
Fugitive Emissions Rule consistent with our original intent, which we
believe was broadly understood. We believe that soliciting public
comment on this interim rule prior to making it effective would be
contrary to the public interest because it is in the public interest to
correct the ambiguity contained in the current stay as expeditiously as
possible to avoid potential confusion regarding the regulatory text.
The NSR program is a vital component of the Act's regime for protecting
public health, and it is in the public's interest that the requirements
of the program be clear and unambiguous.
    EPA is also using the APA's good cause exception to make this
interim rule immediately effective. See 5 U.S.C. 553(d)(3). Section
553(d) of the APA generally provides that rules may not take effect
earlier than 30 days after they are published in the Federal Register.
However, section 553(d)(3) provides that if the issuing agency has made
a finding of good cause and has published its reasoning with the rule,
the rule may take effect earlier. EPA has determined that good cause
exists to stay, reinstate, and revise, as appropriate, certain
paragraphs in 40 CFR parts 51 and 52 by interim rule without prior
notice and comment, because prior notice and comment would be
unnecessary and contrary to the public interest for the reasons stated
above. Based on this determination, EPA is making this interim rule
effective immediately.
    Notwithstanding EPA's ``good cause'' finding, we are providing a
30-day public comment period for this interim rule, and upon reviewing
and considering comments received, we will issue a final rule either
affirming the interim rule or affirming the interim rule with
revisions.

C. What specific revisions are being made?

    We are issuing this interim rule to:
     Stay the following paragraphs: 40 CFR 51.165(a)(1)(v)(G)
and (a)(1)(vi)(C)(3), 40 CFR 51.166(b)(2)(v) and (b)(3)(iii)(d), 40 CFR
51 Appendix S II.A.5(vii), and 40 CFR 52.21 (b)(2)(v) and
(b)(3)(iii)(c);
     Reinstate the following paragraphs: 40 CFR 51.165(a)(4),
40 CFR 51.166(i)(1)(ii), 40 CFR 51 Appendix S II.F, and 40 CFR
52.21(i)(1)(vii); and
     Revise the following paragraphs to revert back to the
regulatory text that existed prior to the Fugitive Emissions Rule
amendments: 40 CFR 51.165(a)(1)(ix), (a)(1)(xxviii)(B)(2),
(a)(1)(xxviii)(B)(4), (a)(1)(xxxv)(A)(1), (a)(1)(xxxv)(B)(1),
(a)(1)(xxxv)(C), (a)(1)(xxxv)(D), (a)(2)(ii)(B), (a)(6)(iii),
(a)(6)(iv), and (f)(4)(i)(D); 40 CFR 51.166(a)(7)(iv)(b),
(b)(3)(iii)(c), (b)(20), (b)(40)(ii)(b), (b)(40)(ii)(d), (b)(47)(i)(a),
(b)(47)(ii)(a), (b)(47)(iii), (b)(47)(iv), (r)(6)(iii), (r)(6)(iv), and
(w)(4)(i)(d); 40 CFR 51 Appendix S II.A.6(iii), II.A.9, II.A.24(ii)(b),
II.A.24(ii)(d), II.A.30(i)(a), II.A.30(ii)(a), II.A.30(iii),
II.A.30(iv), IV.I.1(ii), IV.J.3, IV.J.4, and IV.K.4(i)(d); and 40 CFR
52.21(a)(2)(iv)(b), (b)(3)(iii)(b), (b)(20), (b)(41)(ii)(b),
(b)(41)(ii)(d), (b)(48)(i)(a), (b)(48)(ii)(a), (b)(48)(iii),
(b)(48)(iv), (r)(6)(iii), (r)(6)(iv), and (aa)(4)(i)(d).
    The overall effect of this action is to revert the treatment of
fugitive emissions in applicability determinations to the approach that
applied prior to the Fugitive Emissions Rule on an interim basis, while
EPA completes the reconsideration.

IV. Fugitive Emissions Rule Reconsideration

    Following the public comment period, EPA will issue a final rule
either affirming the interim rule or affirming the interim rule with
changes. The final rule will be in effect until EPA completes its
reconsideration of the Fugitive Emissions Rule. We intend to propose
and finalize a rule based on the results of the reconsideration by
October 4, 2012.

V. Statutory and Executive Order Reviews

A. Executive Order 12866: Regulatory Planning and Review

    This action is not a ``significant regulatory action'' under
Executive Order (EO) 12866 (58 FR 51735, October 4, 1993), because it
does not raise novel legal or policy issues. Accordingly, this action
is not subject to review under EO 12866.

B. Paperwork Reduction Act

    This action does not impose any new information collection burden
under the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et
seq. Burden is defined at 5 CFR 1320.3(b). This action only corrects
inadvertent errors in the existing stay of the regulations at 40 CFR
parts 51 and 52 concerning the inclusion of fugitive emissions and
further stays the regulations until EPA completes its reconsideration.
    The Office of Management and Budget (OMB) has previously approved
the information collection requirements contained in the existing
regulations (40 CFR parts 51 and 52) under the provisions of the
Paperwork Reduction Act, 44 U.S.C. 3501 et seq., and has assigned OMB
control number 2060-0003. The OMB control numbers for EPA's regulations
in 40 CFR are listed in 40 CFR part 9.

C. Regulatory Flexibility Act

    This interim rule is not subject to the Regulatory Flexibility Act
(RFA), which generally requires an agency to prepare a regulatory
flexibility analysis for any rule that will have a significant economic
impact on a substantial number of small entities. The RFA applies only
to rules subject to notice and comment rulemaking requirements under
the APA or any other statute. This rule is not subject to notice and
comment requirements under the APA or any other statute because,
although the rule is subject to the APA, the Agency has invoked the
``good cause'' exemption under 5 U.S.C. 553(b), therefore it is not
subject to the notice and comment requirement.

D. Unfunded Mandates Reform Act

    This action contains no federal mandates under the provisions of
Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), 2 U.S.C.
1531-1538 for state, local, or tribal governments or the private
sector. This action only corrects inadvertent errors in the existing
stay of the regulations at 40 CFR parts 51 and 52 concerning the
inclusion of fugitive emissions and further stays the regulations until
EPA completes its reconsideration. Therefore, this action is not
subject to the requirements of sections 202 or 205 of UMRA.
    This action is also not subject to the requirements of section 203
of UMRA because it contains no regulatory requirements that might
significantly or uniquely affect small governments.

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, as
specified in EO 13132. This action only corrects inadvertent errors in
the existing stay of the regulations at 40 CFR parts 51 and 52
concerning the inclusion of fugitive emissions and further stays the
regulations until EPA completes its reconsideration. Thus, EO 13132
does not apply to this rule.

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

    This action does not have tribal implications, as specified in EO
13175 (65 FR 67249, November 9, 2000). This action will not impose any
new obligations or enforceable duties on tribal governments. Thus, EO
13175 does not apply to this action.

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

    EPA interprets EO 13045 (62 FR 19885, April 23, 1997) as applying
only to those regulatory actions that concern health or safety risks,
such that the analysis required under section 5-501 of the EO has the
potential to influence the regulation. This action is not subject to EO
13045 because it does not establish an environmental standard intended
to mitigate health or safety risks.

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

    This action is not subject to EO 13211 (66 FR 28355, May 22, 2001),
because it is not a significant regulatory action under Executive Order
12866.

I. National Technology Transfer and Advancement Act

    Section 12(d) of the National Technology Transfer and Advancement
Act of 1995 (``NTTAA''), Public Law 104-113, 12(d) (15 U.S.C. 272 note)
directs EPA to use voluntary consensus standards in its regulatory
activities unless to do so would be inconsistent with applicable law or
otherwise impractical. Voluntary consensus standards are technical
standards (e.g., materials specifications, test methods, sampling
procedures, and business practices) that are developed or adopted by
voluntary consensus standards bodies. NTTAA directs EPA to provide
Congress, through OMB, explanations when the Agency decides not to use
available and applicable voluntary consensus standards.
    This action does not involve technical standards. Therefore, EPA
did not consider the use of any voluntary consensus standards.

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

    Executive Order 12898 (59 FR 7629, Feb. 16, 1994) establishes
Federal executive policy on environmental justice. Its main provision
directs federal agencies, to the greatest extent practicable and
permitted by law, to make environmental justice part of their mission
by identifying and addressing, as appropriate, disproportionately high
and adverse human health or environmental effects of their programs,
policies, and activities on minority populations and low-income
populations in the United States.
    EPA has determined that this interim rule will not have
disproportionately high and adverse human health or environmental
effects on minority or low income populations because it only corrects
inadvertent errors in the existing stay of the regulations at 40 CFR
parts 51 and 52 concerning the inclusion of fugitive emissions and
further stays the regulations until EPA completes its reconsideration.

K. Congressional Review Act

    The Congressional Review Act, 5 U.S.C. 801, et seq., as added by
the Small Business Regulatory Enforcement Fairness Act of 1996,
generally provides that before a rule may take effect, the agency
promulgating the rule must submit a rule report, which includes a copy
of the rule, to each House of the Congress and to the Comptroller
General of the United States. Section 808 allows the issuing agency to
make a rule effective sooner than otherwise provided by the CRA if the
agency makes a good cause finding that notice and public procedure is
impracticable, unnecessary, or contrary to the public interest. This
determination must be supported by a brief statement, 5 U.S.C. 808(2).
As stated previously, EPA has made such a good cause finding, including
the reasons therefore, and established an effective date of March 30,
2011. EPA will submit a report containing this rule and other required
information to the United States Senate, the United States House of
Representatives, and the Comptroller General of the United States prior
to publication of the rule in the Federal Register. This action is not
a ``major rule'' as defined by 5 U.S.C. 804(2).

VI. Statutory Authority

    The statutory authority for this action is provided by section
301(a) of the CAA as amended (42 U.S.C. 7601(a)).

    (iii) For a new emissions unit, the baseline actual emissions for
purposes of determining the emissions increase that will result from
the initial construction and operation of such unit shall equal zero;
and thereafter, for all other purposes, shall equal the unit's
potential to emit.
    (iv) For a PAL for a stationary source, the baseline actual
emissions shall be calculated for existing electric utility steam
generating units in accordance with the procedures contained in
paragraph (b)(48)(i) of this section, for other existing emissions
units in accordance with the procedures contained in paragraph
(b)(48)(ii) of this section, and for a new emissions unit in accordance
with the procedures contained in paragraph (b)(48)(iii) of this
section.

    (vii) The source or modification would be a major stationary source
or major modification only if fugitive emissions, to the extent
quantifiable, are considered in calculating the potential to emit of
the stationary source or modification and the source does not belong to
any of the following categories:
    (a) Coal cleaning plants (with thermal dryers);
    (b) Kraft pulp mills;
    (c) Portland cement plants;
    (d) Primary zinc smelters;
    (e) Iron and steel mills;
    (f) Primary aluminum ore reduction plants;
    (g) Primary copper smelters;
    (h) Municipal incinerators capable of charging more than 250 tons
of refuse per day;

shall not include ethanol production facilities that produce ethanol by
natural fermentation included in NAICS codes 325193 or 312140;
    (u) Fossil-fuel boilers (or combination thereof) totaling more than
250 million British thermal units per hour heat input;
    (v) Petroleum storage and transfer units with a total storage
capacity exceeding 300,000 barrels;
    (w) Taconite ore processing plants;
    (x) Glass fiber processing plants;
    (y) Charcoal production plants;
    (z) Fossil fuel-fired steam electric plants of more than 250
million British thermal units per hour heat input;

    (iii) The owner or operator shall monitor the emissions of any
regulated NSR pollutant that could increase as a result of the project
and that is emitted by any emissions unit identified in paragraph
(r)(6)(i)(b) of this section; and calculate and maintain a record of
the annual emissions, in tons per year on a calendar year basis, for a
period of 5 years following resumption of regular operations after the
change, or for a period of 10 years following resumption of regular
operations after the change if the project increases the design
capacity or potential to emit that regulated NSR pollutant at such
emissions unit.
    (iv) If the unit is an existing electric utility steam generating
unit, the owner or operator shall submit a report to the Administrator
within 60 days after the end of each year during which records must be
generated under paragraph (r)(6)(iii) of this section setting out the
unit's annual emissions during the calendar year that preceded
submission of the report.
