[EPA-R01-OAR-2014-0796; EPA-R01-OAR-2014-0862; FRL-9926-73-Region 1]

Approval and Promulgation of Air Quality Implementation Plans; 
New Hampshire; Nonattainment New Source Review and Prevention of 
Significant Deterioration Program

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing to 
conditionally approve the New Hampshire November 15, 2012 State 
Implementation Plan (SIP) revisions that are intended to ensure that 
the State's Prevention of Significant Deterioration (PSD) and 
Nonattainment New Source Review (NNSR) programs are consistent with the 
federal PSD and NNSR program requirements. In a letter dated March 20, 
2015, the New Hampshire Department of Environmental Services (NH DES) 
committed to revising its regulations no later than one year from the 
date when EPA publishes a notice of final conditional approval, and to 
submitting the revised regulations to EPA for approval into the SIP. 
EPA is also proposing to fully approve a July 1, 2003 SIP revision that 
clarifies two definitions related to New Hampshire's permitting 
programs. These actions are being taken in accordance with the Clean 
Air Act (CAA).

I. What action is EPA proposing in this document?

    EPA is proposing three actions in this document. First, EPA is 
proposing to conditionally approve revisions to the New Hampshire PSD 
program under PART Env-A 619, ``Prevention of Significant 
Deterioration.'' EPA originally proposed approval of the State's PSD 
program revisions on January 21, 2015. See 80 FR 2860. EPA is 
reproposing to approve the State's PSD program as a conditional 
approval because subsequent to EPA's January 21, 2015 Federal Register 
document, EPA concluded that New Hampshire's regulations did not 
contain a provision, consistent with 40 CFR 51.166(q)(2)(iv), requiring 
notice of a draft PSD permit to state air agencies whose lands may be 
affected by emissions from the permitted source. In a letter from New 
Hampshire dated March 20, 2015, the State committed to revise its 
regulations, no later than one year from EPA's notice of a final 
conditional approval, to include the additional public notice procedure 
in its regulations and to submit the revision to EPA for approval into 
the SIP.
    EPA is also proposing to conditionally approve revisions to New 
Hampshire's NNSR program SIP submitted on November 15, 2012. The 
approval is conditioned on New Hampshire submitting in a timely manner 
two requirements missing from its rules: (1) Provisions that meet the 
federal regulations for ``reasonable possibility,'' applicable to 
projects at major stationary sources that are not major modifications 
based on the actual-to-projected actual test but have a ``reasonable 
possibility'' of resulting in a significant emission increase; and (2) 
provisions stating that approval to construct shall not relieve any 
owner or operator of the responsibility to comply fully with applicable 
provisions of the plan and any other requirements under local, state or 
federal law. In a letter dated March 20, 2015, the NH DES committed to 
revising its NNSR regulations to include the requirements above and to 
submitting the revised regulations to EPA for approval into the SIP.
    Finally, EPA is proposing to approve New Hampshire's July 1, 2003 
SIP revision that modifies two definitions in PART Env-A 101, ``Permit 
definitions:'' (1) ``minor permit amendment,'' and (2) ``state permit 
to operate.'' These revisions are intended to clarify the State's 
definitions relevant to certain permitting transactions and to render 
them consistent with the requirements in the State's permitting rules.

II. Why is EPA reproposing its January 21, 2015 proposed approval of 
New Hampshire's November 15, 2012 PSD program SIP submittal?

    EPA's original proposal to approve the November 15, 2012 revisions 
to New Hampshire's PSD program is described in detail in the January 
21, 2015 Federal Register document. See 80 FR 2860. In the document, 
EPA noted that public participation requirements for New Hampshire's 
PSD program were first approved in October 28, 2002. In the November 
15, 2012 submittal, New Hampshire renumbered its State citation for the 
public notice procedures but did not include any substantive revisions 
to the language. However, after reviewing New Hampshire's rules to 
determine compliance with the federal infrastructure SIP requirements 
under CAA section 110, EPA concluded that New Hampshire's regulations 
did not contain a provision, consistent with 40 CFR 51.166(q)(2)(iv), 
requiring notice of a draft PSD permit to be sent to state air agencies 
whose lands may be affected by emissions from the permitted source. As 
noted above, EPA is now proposing to conditionally approve New 
Hampshire's PSD program based on the State's commitment to revise its 
regulation and to submit it to EPA for approval into the SIP.

III. What comments did EPA receive during the comment period for New 
Hampshire's PSD proposed program approval?

    EPA received one comment from Earthjustice during the comment 
period for the proposed approval of the PSD program. Earthjustice 
commented that EPA's January 21, 2015 document proposing approval for 
the State's PSD program was confusing and should have more clearly 
stated that New Hampshire did not incorporate by reference the 
significant impact levels (SILs) for Particulate Matter less than 2.5 
microns (PM2.5) into its PSD SIP. EPA agrees that its 
January 21, 2015 document should have been written more clearly on that 
point. On January 22, 2013, the United States Court of Appeals for the 
District of Columbia Circuit granted a request from EPA to vacate and 
remand the portions of the PM2.5 PSD Increment-SILs-SMC Rule 
(40 CFR 51.166(k)(2) and 40 CFR 52.21(k)(2)) addressing the SILs for 
PM2.5 so that EPA could voluntarily correct an error in 
these provisions. See Sierra Club v. EPA, 705 F.3d 458, 463-66 (D.C. 
Cir. 2013). (The court declined to vacate the SILs provision at 40 CFR 
51.165(b)(2) that did not contain that same error. Id.) EPA here 
confirms that New Hampshire's November 12, 2012 proposed PSD revisions 
did not incorporate by reference the PM2.5 SIL provision 
under 40 CFR 51.166(k)(2). EPA is also confirming that we are not 
approving 40 CFR 51.166(k)(2) into the SIP.

IV. What action is EPA proposing for New Hampshire's NNSR SIP 
submittal?

    New Hampshire's November 15, 2012 SIP submittal also included 
revisions to the State's NNSR program at PART Env-A 618, 
``Nonattainment New Source Review.'' The revisions incorporated by 
reference into the State's regulations, at PART Env-A 618 
``Nonattainment New Source Review,'' consist of many of the

[[Page 22958]]

provisions of the federal NNSR program codified in the July 1, 2011 
edition of 40 CFR 51.165. New Hampshire incorporated those provisions 
which are appropriate for state implementation (with the exception of 
certain permit application and public notice requirements for which New 
Hampshire submitted its own equivalent language and with the exception 
of two definitions for which New Hampshire established its own 
language, as described below). EPA's Technical Support Document (TSD) 
sets forth in detail which provisions of 40 CFR 51.165 were 
incorporated by the State and which were not. EPA's TSD is available as 
part of the docket and administrative record for this action. The 
State's NNSR submittal requested that EPA approve the revisions into 
the State's SIP-approved NNSR program. The State's submitted NNSR 
program includes provisions that comply with the requirements in EPA's 
December 31, 2002 Final NSR Improvement Rules and EPA's May 16, 2008 
Final Rules Governing the Implementation of NSR for Fine Particulate 
Matter (i.e., particulate matter less than 2.5 micrometers 
(PM2.5)). EPA is proposing to conditionally approve PART 
Env-A 618 because the State's submittal did not include: (1) provisions 
for ``reasonable possibility'' established in 40 CFR 51.165(a)(6) and 
(a)(7); and (2) provisions required under 40 CFR 51.165(a)(5)(i) 
providing that approval to construct shall not relieve any owner or 
operator of the responsibility to comply fully with applicable 
provisions of the plan and any other requirements under local, State or 
Federal law. By letter dated March 20, 2015, the State committed to 
revise its regulations and to submit them to EPA for approval into the 
SIP no later than one year from the date of EPA's notice of a final 
conditional approval. We also note that PART Env-A 618, on which EPA is 
today taking action, will supersede all other versions of the NNSR 
rules earlier approved by EPA into New Hampshire's SIP.

A. What is the background for New Hampshire's November 15, 2012 NNSR 
program SIP submittal?

    New Hampshire's November 15, 2012 SIP submittal adopting provisions 
from the July 1, 2011 edition of 40 CFR 51.165 (with the exceptions 
mentioned above and described in more detail in EPA's TSD) into the 
SIP, involves the addition of several major changes to the State's NNSR 
rules since EPA last approved the State's NNSR program on July 27, 
2001. As mentioned earlier, the exact provisions of the federal 
regulations which are and are not being incorporated by reference into 
the New Hampshire SIP in this action are contained in EPA's TSD for 
this rulemaking. The new NNSR provisions, i.e., those that are 
different than the NNSR provisions earlier approved by EPA into New 
Hampshire's SIP, are summarized below in the next two sections (IV.B. 
and IV.C) of this document. The State's November 15, 2012 SIP submittal 
retains much of the substantive content of the major NNSR rule 
provisions last approved into the SIP on July 27, 2001 but also 
incorporates changes to the federal regulations that occurred since 
that time, i.e. in December 2002. The already existing provisions 
include, among other things, requirements for major stationary sources 
to obtain emission reductions (``offsets'') from existing stationary 
sources to ensure new stationary sources do not interfere with state 
plans to achieve the National Ambient Air Quality Standards (NAAQS) and 
requirements that major stationary sources apply emissions controls 
that constitute the lowest achievable emission rate (LAER) which is 
derived from the most stringent emission limitation contained in any 
state implementation plan or achieved in practice for that class or 
category of stationary source.

B. What revisions did EPA make in December 31, 2002?

    EPA issued a Final Rule entitled, ``Prevention of Significant 
Deterioration (PSD) and Nonattainment New Source Review (NNSR): 
Baseline Emissions Determination, Actual-to-Future-Actual Methodology, 
Plantwide Applicability Limitations, Clean Units, Pollution Control 
Projects'' (67 FR 80185, December 31, 2002). The rule made a number of 
changes to the applicability requirements of the federal NNSR rule 
including the following:
     A new definition of ``actual emission baseline'' that 
defines an emission unit's pre-modification actual emissions;
     New ``Applicability Procedures'' under 40 CFR 51.165(a)(2) 
that define the test method used to calculate the emission increase 
from the construction or modification of new or existing emission 
units;
     The expansion of the ``Actual-to-Projected Actual'' 
applicability test to determine if projects at non-Electric Utility 
Steam Generating Units (non-EUSGU) are major modifications. (The pre-
2002 federal NSR regulations restricted the Actual-to-Projected Actual 
applicability test to EUSGUs only);
     New procedures requiring stationary sources to monitor, 
keep records and report emissions from projects at existing emission 
units if there is a reasonable possibility (as defined in 40 CFR 
51.165(a)(6)(vi)) that a project that is determined pre-construction 
not to be a major modification may actually in the future result in a 
significant emission increase; and
     The addition of the optional ``Plantwide Applicability 
Test'' (PAL) for all source categories.
    The Federal Register document for the December 2002 NSR rule gave 
state permitting agencies until January 2, 2006 to submit SIP 
amendments that implemented the new federal revisions or, if a state 
permitting agency did not submit any SIP amendments or submitted 
amendments that differed from the federal rules, a demonstration 
showing that its existing permitting program or amended permitting 
program is at least as stringent as EPA's revised program. In addition, 
federal regulations governing SIP-approved NNSR rules at 40 CFR 51.165 
``Permit Requirements'' require that all state plans use the specific 
definitions as promulgated by EPA. Deviations from the federal 
definitions will be approvable by EPA only if the state specifically 
demonstrates that the submitted definition is more stringent than, or 
at least as stringent in all respects as, the corresponding federal 
definition.
    The final document for the December 2002 NSR rule at http://www.epa.gov/NSR/fr/20021231_80186.pdf provides a full description of 
the NSR improvements, the requirements for SIP submittals, and the 
final amended federal rule for SIP-approved NNSR programs at 40 CFR 
51.165 ``Permit Requirements.''

C. What revisions did EPA make in May 16, 2008?

    EPA issued a Final Rule governing the implementation of NSR for 
PM2.5. (73 FR 28321, May 16, 2008). The rule includes the 
new major stationary source applicability threshold level for major 
stationary sources of PM2.5. A stationary source is defined 
as a major stationary source and subject to the PM2.5 NNSR 
requirements if it emits 100 or more tons per year (tpy) of 
PM2.5.
    The rule also identified the following list of pollutants that 
contribute to PM2.5 formation and a description of whether 
the pollutant, as a precursor to PM2.5, is regulated under 
the NNSR rules.
     Direct emissions of PM2.5--regulated under the 
NNSR rule;

[[Page 22959]]

     Sulfur dioxide (SO2)--regulated under the NNSR 
rule;
     Nitrogen oxides (NOX)--regulated under the NNSR 
rule unless the state demonstrates that NOX emissions are 
not a significant contributor to the formation of PM2.5 for 
an area(s) in the state;
     Volatile organic compounds (VOC)--not regulated under the 
NNSR rule unless the state demonstrates that VOC emissions are a 
significant contributor to the formation of PM2.5 for an 
area(s) in the state; and
     Ammonia--not regulated under the NNSR rule unless the 
state demonstrates that ammonia emissions are a significant contributor 
to the formation of PM2.5 for an area(s) in the state.
    The rule also identifies the following significant emission rates 
used to determine if increases in direct emissions of PM2.5 
or increases in PM2.5 precursors from a construction project 
at an existing facility result in major modifications that are then 
subject to the NNSR rule:
     Direct PM2.5 emissions--10 tons per year (tpy)
     SO2 emissions--40 tpy
     NOX emissions--40 tpy
     VOC emissions (if regulated) 40 tpy unless the state 
demonstrates that a lower rate is appropriate.

V. What is EPA's analysis of New Hampshire's proposed NNSR program SIP 
revisions?

A. What requirements did EPA apply in deciding to propose conditional 
approval of New Hampshire's SIP submittal?

    Section 110(a)(1) of the CAA requires each state to submit to EPA a 
plan which provides for the implementation, maintenance and enforcement 
of each NAAQS. These plans, generally referred to as the SIP, include 
numerous air quality monitoring, emission inventory, and emission 
control requirements designed to obtain and maintain the NAAQS within 
the state. The CAA requires states to adopt SIP revisions into state 
regulations and to submit the revisions to EPA for approval into the 
state's SIP. Section 110(l) of the CAA states that EPA shall not 
approve a revision to the SIP if the revision would interfere with any 
applicable requirement concerning attainment (of the NAAQS) and 
reasonable further progress (as defined in CAA section 7501) or any 
other requirement of the CAA.

B. What provisions did New Hampshire include in its November 15, 2012 
NNSR SIP submittal?

    New Hampshire's November 15, 2012 SIP submittal added or revised 
the following provisions to its NNSR Program under PART Env-A 618 
Nonattainment New Source Review. The provisions include requirements 
from 40 CFR 51.165 previously incorporated by reference into New 
Hampshire's SIP on July 27, 2001, additional or amended requirements 
contained in the July 2011 version of 40 CFR 51.165, and certain new 
and previously approved state permit program requirements, including 
permit application and permit issuance procedures and other 
requirements necessary to implement the NNSR program.

 PART Env-A 618.08: Procedure for acquiring and Implementing 
Emission Offsets
 PART Env-A 618.09: Establishing a PAL
 PART Env-A 618.10 Department Review and Public Notice

    The following is a description of each section.
    PART Env-A 618.01 Purpose defines the purpose of the part to 
implement the NNSR program as set forth in sections 171 through 193 of 
the CAA and the July 1, 2011 edition of 40 CFR 51.165.
    PART Env-A 618.02 Applicability identifies the stationary sources 
subject to the state NNSR program: New major stationary source or major 
modifications of a regulated NSR pollutant located in an area 
designated as nonattainment under 40 CFR 81.330, or new major 
stationary sources or major modifications for NOX or VOC if 
the stationary source is located in the Northeast Ozone Transport 
region (OTR) as defined in PART Env-A 618.03(b)(3).
    The section also requires projects to use emission calculations 
described in 40 CFR 51.165(a)(2)(ii)(A) through (F) to determine if the 
project is a new major stationary source or new major modification.
    In addition, if a new stationary source or modification is 
determined to be a major stationary source or major modification solely 
by virtue of a relaxation in any enforceable limitation established 
after August 7, 1980 on the capacity of the stationary source or 
modification otherwise to emit a pollutant, such as a restriction on 
hours of operation, then the provisions of this part shall apply to the 
stationary source or modification as though construction had not yet 
commenced on the stationary source or modification.
    PART Env-A 618.03 Definitions adopts the specific definitions 
contained in the July 1, 2011 edition of 40 CFR 51.165(a)(1) and (f)(2) 
with the following clarifications: The NH DES revised the federal 
definitions of ``Baseline actual emissions'' and ``Reasonable period.'' 
An analysis of the State's revisions to the federal definitions of the 
terms ``Baseline actual emissions'' and ``Reasonable period'' is found 
in section V.D of this document. The section also included five 
additional definitions not specifically defined in the federal NNSR 
regulations, but relevant to the program: ``Emission offset,'' 
``Emission offset ratio,'' ``Northeast Ozone Transport Region,'' 
``Offset source,'' and ``Ozone season.''
    PART Env-A 618.04 Owner or Operator Obligations includes the 
following requirements:
     The owner or operator of any new major stationary source 
or major modification subject to this part shall comply with LAER;
     obtain offsets for the increase in emissions for the 
project in accordance with PART Env-A 618.07; and
     obtain a NNSR permit prior to commencement of 
construction.
    In addition, the owner or operator of an existing major stationary 
source with a Plantwide applicability limit (PAL) shall comply with the 
provisions of its PAL.
    PART Env-A 618.05 Implementation Plan Requirements ensures, in 
accordance with section 173(a)(4) of the CAA, that NH DES will not 
issue a permit or permits to a stationary source to which the 
requirements of PART Env-A 618 apply if the EPA Administrator has 
determined that the applicable implementation plan is not being 
adequately implemented for the nonattainment area in which the proposed 
stationary source is to be constructed or modified.
    PART Env-A 618.06 Permit Application Requirements identifies the 
procedures to file with NH DES, NNSR and PAL permit applications. The 
section also identifies the items that should be included in an 
application including: (1) A control technology evaluation to 
demonstrate that a new major stationary source or major modification 
will meet LAER; (2) a documented plan to obtain creditable

[[Page 22960]]

emission reduction offsets in accordance with PART Env-A 618.07; (3) a 
demonstration showing that all major stationary sources in New 
Hampshire under common ownership are in compliance; and (4) an analysis 
of alternative sites, sizes, production processes, and an environmental 
control techniques demonstration showing the benefits of the proposed 
stationary source significantly outweigh the environmental and social 
costs imposed as a result of its location, construction, or 
modification. In addition, a PAL application shall contain information 
required pursuant to 40 CFR 51.165(f)(3).
    PART Env-A 618.07 Emission Offset Requirements identifies the 
requirements for offsets including, but not limited to, defining: (1) 
the use of actual emissions from the stationary source providing offset 
credits as the baseline for determining emission offsets; (2) the 
offset ratio requirements for different ozone nonattainment 
designations; and (3) the location requirements restricting where a 
stationary source may obtain offsets. The section includes requirements 
for a stationary source seeking offsets to demonstrate that the 
stationary source of the offsets causes or contributes to a violation 
of a NAAQS in the nonattainment area which the new or modified 
stationary source is proposed to be located. The section also requires 
that offsets obtained outside of New Hampshire be subject to a 
federally enforceable permit or other federally enforceable document 
approved by the state or governing jurisdiction in which the offset 
stationary source is located.
    The section also states that offsets shall not include: (1) Any 
reductions from compliance, or scheduled compliance, with applicable 
rules in effect prior to the permit application of the new or modified 
stationary source; (2) Reductions required to meet RACT or acid 
deposition provisions of the Act, as stipulated in the General Preamble 
for the Implementation of Title I of the Clean Air Act Amendments of 
1990, 57 FR 13553, III.G.2.e; or 3) Reductions required to meet any 
other provisions of Env-A 100 et seq. and the Act.
    PART Env-A 618.08 Procedures for Acquiring and Implementing 
Emission Offsets identifies requirements for owners and operators to 
document the offset pollutant, actual and potential estimates of each 
new pollutant, the offset stationary source and location, the actual 
and allowable annual estimate of each pollutant for the offset 
stationary source prior to the effective date of the offset, potential 
annual estimates of each pollutant of the new stationary source after 
the effective date of the offset, and for NOX and VOC 
emissions, the ozone season annual emissions estimate from the new 
stationary source.
    The section also requires stationary sources obtaining offsets from 
outside New Hampshire to file documentation with the NH DES verifying 
that the offset stationary source has obtained a federally enforceable 
permit or other federally enforceable documentation for the emission 
reduction control measures pertaining to the offsets for the new 
stationary source.
    The section also allows the use of emission reduction credits 
(ERCs) in accordance to PART Env-A 3006.04 to satisfy NNSR emissions 
offset requirements. Stationary sources may also use discrete emission 
reductions (DERs) to meet the offset requirements provided the DERs 
comply with the requirements of section 173 of the Act, 40 CFR 
51.165(a) and PART Env-A 3108.02.
    Env A 618.09 Establishing a PAL identifies the requirements to 
establish and implement a PAL in accordance with 40 CFR 51.165(f)(1), 
(4) and (6) through (14) except that public participation procedures 
identified in PART Env-A 618.10(b) and (c) shall be used.
    PART Env-A 618.10 Department Review and Public Notice requires 
stationary sources applying for a PAL permit to file an application. 
The regulation specifies that NH DES will address all material comments 
received during the comment period before taking a final action on a 
PAL permit application. Applications to comply with NNSR or to 
establish a PAL permit shall be subject to the public notice procedures 
specified in PART Env-A 621.04 including the requirement for a 30-day 
public notice and comment period and permit appeal procedures under the 
state judicial review regulations.

C. How did the New Hampshire November 15, 2012 NNSR SIP submittal meet 
new and existing NNSR program requirements?

    With the exception of the definitions of the terms ``Baseline 
actual emissions'' and ``Reasonable period,'' the NH DES's November 15, 
2012 SIP submittal incorporated by reference into the State regulation 
the definitions for a SIP-approved nonattainment NSR program under 40 
CFR 51.165(a)(1) and the definitions for PALs under 40 CFR 
51.165(f)(2). The submittal also included five additional definitions: 
``Emission offset,'' ``Emission offset ratio,'' ``Northeast Ozone 
Transport Region,'' ``Offset source,'' and ``Ozone season'' for the 
purpose of clarifying the State's NNSR requirements. The definitions 
for ``Emission offset,'' ``Emission offset ratio'' and ``Ozone season'' 
were previously approved by EPA into the SIP and clarify the offset 
requirements under New Hampshire's NNSR program. The definition for the 
``Northeast Ozone Transport Region'' was also previously approved by 
EPA into the SIP and means the same geographical area as defined under 
Section 184(a) of the CAA. The definition of ``Offset source'' replaces 
the previously approved SIP definition of ``Offset donor source'' and 
identifies potential sources of emissions from which a new or modified 
stationary source may obtain emission offsets. The additional 
definitions help clarify the offset requirements under New Hampshire's 
NNSR program and are consistent with all federal requirements under the 
CAA for approval into the SIP.
    By incorporating by reference the federal provisions under 40 CFR 
51.165 (with the exceptions noted earlier and in EPA's TSD) the vast 
majority of the State's proposed SIP revisions satisfy the existing 
SIP-approved NNSR program requirements approved on July 27, 2001, the 
December 31, 2002 NSR Improvement Rule, and the May 16, 2008 
PM2.5 NSR Rule.\1\ The two conditional approval issues that 
are missing from New Hampshire's submittal are described earlier and 
later in this document.
---------------------------------------------------------------------------

    \1\ New Hampshire's few changes to definitions used in the 
federal regulations and use of several additional clarifying 
definitions, as explained in this document, are also approvable 
because they are consistent with all CAA requirements for approval 
into the SIP.
---------------------------------------------------------------------------

    The NH DES submittal also expanded upon the emissions offset 
provisions previously approved into the SIP. As noted, the submittal 
includes a new definition for ``Emission offset'' under PART Env-A 
618.03 requiring reductions in pollutants achieved at an existing 
stationary source to meet criteria specified in 40 CFR 51.165(a)(3). 
The NH DES also included two new sections in the NNSR program; Env 
618.07, ``Emission Offset Requirements'' and Section PART Env-A 618.08, 
``Procedure for Acquiring and Implementing Emissions Offsets.''
    As described above, PART Env-A 618.07 identifies the specific 
provisions applicable to all offset emissions. These provisions include 
requirements that offsets: (1) Be surplus; (2) obtained from an area 
designated with an equal or higher nonattainment classification; (3) 
obtained in an amount equal to or exceeding a one-to one ratio, or 
another

[[Page 22961]]

ratio as required by the nonattainment designation; and, 4) if obtained 
outside the designated area where the new stationary source or 
modification is to be constructed, a demonstration that the offsets 
cause or contribute to a violation of the NAAQS in which the stationary 
source or modification is to be constructed, as allowed under section 
173(c)(1) of the CAA.
    PART Env-A 618.08 identifies the procedures for documenting 
emission reductions used for offsets. Among other requirements, the 
section allows stationary sources subject to the offset provisions to 
use ERCs in accordance with PART Env-A 3006.04. The section also allows 
DERs to meet the offset requirements, provided the DERs comply with the 
requirements of section 173 of the CAA, 40 CFR 51.165(a) and PART Env-A 
3108.02. As explained below, EPA previously has allowed the use of DERs 
to meet a CAA emissions requirement. EPA has determined, given the 
procedures that will apply to the use of DERs and ERCs to meet the NNSR 
emissions offset requirements, that it is appropriate and consistent 
with CAA requirements to approve these provisions into New Hampshire's 
SIP.
    In EPA's approval of New Hampshire's Reasonably Available Control 
Technology (RACT) for Nitrogen Oxide (NOX) and Volatile 
Organic Compounds (79 FR 49458, August 21 2014), EPA allowed stationary 
sources subject to the State's RACT rule to comply by the purchase and 
generation of DER credits pursuant to PART Env-A 3100. The approval 
further states, since PART Env-A 3100 has not been approved into the 
SIP, any order issued by New Hampshire that allows the use of PART Env-
A 3100 to comply with NOX RACT will need to be approved into 
New Hampshire's SIP as a source specific SIP revision.
    Similar to the RACT rule, since PART Env-A 3000 and PART Env-A 3100 
have not been approved by EPA into the SIP, any NNSR permit issued by 
New Hampshire that allows for the use of ERCs and/or DERs to meet an 
offset requirement would first need the ERC or DER offset to be 
approved by EPA into the SIP before the NNSR permit could be issued. 
Each individual SIP approval of a stationary source's use of DERs and/
or ERCs for the purpose of meeting the NNSR emissions offset 
requirement, would be required to meet the requirements identified in 
PART Env-A 618.07 and PART Env-A 618.08 and to satisfy all offset and 
any other relevant requirements of the CAA before EPA would be able to 
approve the use of the DERs and/or ERCs into the SIP for a specific 
proposed new major stationary source or modification.

D. How did New Hampshire demonstrate that the definitions of ``Baseline 
actual emissions'' and ``Reasonable period'' are as stringent as the 
corresponding federal definitions?

1. ``Baseline Actual Emissions'' Analysis
    The ``Baseline actual emissions'' definition is used in all major 
stationary source applicability tests and defines the actual emissions 
from a stationary source before the project. The difference between the 
pre-project ``actual emission baseline'' and the post-project 
``projected actual emissions'' determines the emission increase from a 
project.
    The federal definition of ``Baseline actual emissions'' at 40 CFR 
51.165(a)(1)(xxxv) defines separate baseline emissions calculations for 
existing electric utility steam generating units (EUSGU) and all other 
existing emission units other than EUSGU. The key elements of the 
definition relevant to this document are as follows:
     Existing EUSGU: The owner/operator may select any 
consecutive 24-month period for each pollutant, without the need for a 
demonstration, within the 5-year period immediately preceding when the 
owner/operator begins actual construction of the project. The reviewing 
authority may allow the use of a different time period upon a 
determination showing the time period is more representative of normal 
stationary source operations. A different consecutive 24-month period 
can be used for each regulated pollutant.
     All other existing emission units: The owner/operator may 
select any consecutive 24-month period in the 10-year period 
immediately preceding either the date the owner/operator begins actual 
construction or the date a completed permit application is received by 
the reviewing authority for a permit, whichever is earlier. No other 
different time period is allowed. A different consecutive 24-month 
period can be used for each regulated pollutant.
    The NH DES definition tracks the requirements in 40 CFR 
51.165(a)(1)(xxxv) except for the following differences:
     Unlike the federal definitions, the State uses the same 
definition for EUSGUs and non-EUSGUs.
     Under the State's definition, in establishing baseline 
actual emissions for a project, the owner/operator presumptively shall 
select the same consecutive 24-month period for all pollutants; and the 
consecutive 24-month period shall be selected from within the 5-year 
period immediately preceding the date when the owner/operator begins 
actual construction of the project. However, the NH DES shall allow the 
use of a different consecutive 24-month time period for all pollutants, 
up to 10 years immediately preceding the date when the owner/operator 
begins actual construction of the project, or allow the use of a 
different consecutive 24-month period for different pollutants within 
that 10 year period, upon determining (after adequate demonstration by 
the applicant) that the alternative time period is more representative 
of normal stationary source operations.
    Forty CFR 51.165(a)(1) requires that all state plans use the 
specific definitions as promulgated by EPA. Deviations from the federal 
wording for each definition will be approved only if the state 
specifically demonstrates that the submitted definition is more 
stringent, or at least as stringent in all respects, as the 
corresponding federal definition.
    As part of the December 2002 NSR final rule, EPA prepared a 
November 21, 2002, ``Supplemental Analysis of the Environmental Impact 
of the 2002 Final NSR Improvement Rules (Supplemental Analysis).'' The 
Supplemental Analysis provided a description of the NSR reform rules 
and an analysis demonstrating that the reform rule's environmental 
benefits were equivalent to or more stringent than the existing pre-
reform rules. For the addition of the definition of ``Baseline actual 
emissions,'' EPA concluded that the use of a 10 year period to select a 
baseline is a reasonable period considering the variability of 
different business cycles. EPA believes the effect from the new 
definition is small and would not alter the baseline for 90% of the 
stationary sources. For the remaining 10%, EPA cannot draw general 
conclusions about how many stationary sources would or would not 
receive an alternative baseline nor estimate what emission consequences 
would result. EPA's complete analysis of the definition of ``Baseline 
Actual Emissions'' can be found at http://www.epa.gov/nsr/documents/nsr-analysis.pdf.
    The NH DES included as part of its SIP submittal a November 16, 
2012 memorandum entitled ``Supplemental Information for SIP Revision 
Request Parts of PART Env-A 600, Statewide Permit System.'' Similar to 
the EPA's study and analysis summarized above in the previous 
paragraph, the State's memorandum described the differences between the 
federal and state ``Baseline actual emissions'' definitions and 
described an emissions study that compares the effects of the state and

[[Page 22962]]

federal definition on emission changes to actual stationary sources 
located in New Hampshire. The NH DES's analysis looked at the federal 
definition of baseline actual emission, the State's presumptive or 
default baseline actual emission method (i.e., 24 consecutive months 
selected from the 5 years preceding actual construction for all 
regulated pollutants), and the State's allowed alternative emission 
baseline if the owner/operator could demonstrate normal stationary 
source operations are better represented by:
     Use of an alternative 24-consecutive month period selected 
from the period between 5 to 10 years immediately preceding beginning 
actual construction, and
     use of different 24-consecutive month periods for 
different regulated pollutants, within the period between 5 and 10 
years immediately preceding beginning actual construction.
    For the majority of changes occurring at any type of stationary 
source, the State's presumptive or default baseline actual emissions 
method (using a 24-consecutive month period during the 5 year period 
immediately preceding beginning actual construction) resulted in the 
same or lower baseline emissions as compared to the federal definition. 
For owner/operators that could demonstrate that normal stationary 
source operations were better represented by 24 consecutive months 
selected from the 5 to 10 year period preceding beginning actual 
construction or that different consecutive 24-month periods for 
different regulated pollutants better represent normal stationary 
source operations, the analysis showed that the State's definition 
resulted in baseline emissions that were at least as stringent in all 
cases to the federal definition.
    EPA therefore concludes that the NH DES's definition of ``Baseline 
actual emissions'' is as stringent in all respects as the federal 
definition. The State's definition results in the same emission 
baseline for new emission units, changes to existing EUSGUs, and 
changes at existing units that emit one pollutant and with high 
utilization rates within the last 5 years. For all other changes, the 
State's definition allows the use of baselines selected outside of 5 
years (but before 10 years) and baselines for each regulated pollutant 
where appropriately demonstrated to be as stringent. As a result, any 
difference in the application of the state and federal definitions on 
the selection of baseline actual emissions would be insignificant at 
worst and would therefore result in permit applicability decisions, 
emissions limitations or emissions control requirements that are 
equally stringent.
2. Reasonable Period Analysis
    The NH DES's submittal also revised the definition for ``Reasonable 
period.'' The term ``Reasonable period'' is used in the definition for 
``Net emissions increase'' and defines the contemporaneous period for 
the emission increases and decreases that are used in the calculation 
determining applicability of the NNSR regulations to a particular 
project. Under Sec.  51.165(a)(1)(vi)(C)(1), the reviewing authority is 
authorized to specify the applicable ``Reasonable period.'' Reviewing 
authorities typically use the period defined in the federal Prevention 
of Significant Deterioration (PSD) permitting program. That period 
begins five years before the date construction of the project commences 
and ends when the emissions increase from the project actually occurs.
    The NH DES's definition for ``reasonable period'' uses a period 
that begins five years from the date the NH DES receives a complete 
permit application for a project and ends upon the ``expiration date'' 
of the pre-construction permit issued for the project (at which time a 
NH DES-issued state operating permit for the project becomes 
effective). A ``Reasonable period'' based on a fixed date (i.e., the 
receipt of a complete permit application) ensures the stationary 
source, the permitting authority and the public that the NNSR 
applicability determination for a stationary source or modification 
will not change after the state has reviewed a permit application and 
made a permit decision. Since the 5 year period will not change after 
the complete permit application is received, all contemporaneous 
emission increases and decreases used by the stationary source and 
state to determine NSR applicability will remain in effect.
    Under the federal definition, the 5-year period is based on the 
date construction commences, a date that may change significantly based 
on the many factors that could delay construction. As a result, the 
five year contemporaneous period would also be delayed. Emission 
increases previously within the contemporaneous period could fall 
outside the contemporaneous period and change the applicability of the 
stationary source or modification. In addition, the NH DES version of 
``Reasonable period'' extends out to the expiration date of the 
``temporary'' or preconstruction air permit issued for the project, a 
date compatible with the NH DES's air permitting program. Under the NH 
DES's permit program, the initial preconstruction permit required 
before construction begins is referred to as a temporary permit. 
Temporary permits expire after 18 months. Before expiration, stationary 
sources must complete construction and begin operational testing or, if 
construction has not commenced with the 18 months, reapply for a new 
temporary permit. For those cases where a stationary source has 
completed construction and has begun to operate, the state and federal 
terms provide equivalent results. However, for stationary sources and 
permitting agencies that may have difficulty determining when a new 
stationary source has begun operating due to various stationary source 
startup issues, defining the end date of reasonable period in relation 
to a fixed permit expiration date (and corresponding permit to operate 
issuance date) ensures the state agency and the stationary source that 
NNSR program applicability will not change after initial permit 
decisions have been reviewed and approved. Considering the benefits of 
the NH DES's version of ``Reasonable period'' noted above, EPA 
concludes the State's term for ``reasonable period'' is approvable and 
is as stringent as the federal definition.

E. What are the provisions that New Hampshire needs to submit in order 
for the conditional approval to become a full approval?

    The State's proposed SIP revision did not include two provisions 
that preclude EPA from fully approving the State's proposed NNSR SIP 
revisions. The first missing provision applies to any regulated NSR 
pollutant emitted from projects at existing emission units at a major 
stationary source (other than projects at a source with a PAL) in 
circumstances where there is a reasonable possibility, within the 
meaning of 40 CFR 51.165(a)(6)(vi), that a project not a part of a 
major modification may result in a significant emissions increase of 
such pollutant, and the owner or operator elects to use the projected 
actual method specified in paragraphs (a)(1)(xxviii)(B)(1) through (3) 
for calculating projected actual emissions. These specific procedures 
include additional monitoring, recordkeeping and reporting for those 
projects that exceed 50% of the significant emission increase and 
significant net emission increase for the applicable pollutant. The NH 
DES has committed by letter dated March 20, 2015 to submit for EPA 
approval into the SIP in a timely manner provisions that meet the 
requirements at 40 CFR 51.165(a)(6) and (a)(7) so that EPA may

[[Page 22963]]

at that time fully approve the NH DES's NNSR program.
    The second missing provision from NH DES's submittal is the 
requirement at 40 CFR 51.165(a)(5)(i) that a State approval to 
construct shall not relieve any owner or operator of the responsibility 
to comply fully with applicable provisions of the plan and any other 
requirements under local, State or Federal law. This provision, 
originally part of the SIP and unintentionally left out of the November 
15, 2012 SIP submittal, affirms that sources subject to the NNSR 
program must continue to comply with all other applicable state and 
federal requirements. The NH DES has committed by letter dated March 
20, 2015 to submit for EPA approval into the SIP in a timely manner 
provisions that meet the requirements at 40 CFR 51.165(a)(5)(i) so that 
EPA may at that time fully approve the NH DES's NNSR program.

VI. What action is EPA proposing for New Hampshire's s July 21, 2003 
SIP submittal to its PART Env-A 101: Permit definitions?

    New Hampshire July 23, 2003 SIP submittal clarifies how the State 
addresses minor changes to the permit terms contained in ``Temporary 
Permits'' (i.e., preconstruction air quality permits) and ``State 
Permits to Operate'' issued under the State's PART Env-A 600, Statewide 
Permit System. The current SIP-approved rules do not have definitions 
sufficient to address minor changes to existing permit terms or 
conditions for stationary sources, where the changes would not: (a) 
result in an increase in the amount of a specific air pollutant emitted 
by the source or device; (b) result in the emission of any additional 
air pollutant; or (c) necessitate the use of permit notice and hearing 
procedures.
    To address such minor changes to existing permit terms, the SIP 
submittal included definitions for the terms for ``minor permit 
amendment'' and ``state permit to operate.'' The term ``minor permit 
amendment'' provides for minor changes to conditions in permits other 
than Title V permits (which are not issued pursuant to SIP 
regulations). The term ``state permit to operate'' means a non-Title V 
operating permit issued prior to operation or material modification of 
a stationary source, area stationary source or device. Both definitions 
are consistent with all federal requirements under the CAA for approval 
into the SIP.

VII. Proposed Action

    EPA is proposing to conditionally approve the NH DES's November 15, 
2012 PSD Program submittal originally proposed to be fully approved by 
EPA on January 21, 2015. The reproposed, conditional approval of the 
PSD program is conditioned on the State submitting in a timely manner a 
SIP revision that adds a provision, consistent with 40 CFR 
51.166(q)(2)(iv), requiring notice of a draft PSD permit to state air 
agencies whose lands may be affected by emissions from the permitted 
source.
    EPA is also proposing to conditionally approve PART Env-A 618 
``Nonattainment New Source Review,'' because the NH DES must submit to 
EPA in a timely manner additional provisions that comply with 40 CFR 
51.165(a)(6) and (a)(7) and 40 CFR 51.165(a)(5)(i), i.e., 1) provisions 
for ``reasonable possibility'' established in 40 CFR 51.165(a)(6) and 
(a)(7); and 2) provisions required under 40 CFR 51.165(a)(5)(i) 
providing that approval to construct shall not relieve any owner or 
operator of the responsibility to comply fully with applicable 
provisions of the plan and any other requirements under local, State or 
Federal law.
    Under section 110(k)(4) of the Act, EPA may conditionally approve a 
State's plan based on a commitment from the State to adopt specific 
enforceable measures by a date certain, but not later than 1 year from 
the date of final conditional approval. By letter dated March 20, 2015 
New Hampshire has committed to revising its regulations to be 
consistent with EPA's regulations not later than one year after EPA's 
publication of a notice of final conditional approval. If the State 
fails to do so in a timely manner, this conditional approval will, by 
operation of law, become a disapproval one year from publication of 
that notice of final conditional approval. At that time, the 
conditionally approved SIP revisions would not be part of New 
Hampshire's approved SIP. If that were to occur, EPA would then also 
notify the State by letter. EPA subsequently would publish a notice in 
the Federal Register notifying the public that the conditional approval 
automatically converted to a disapproval. If the State meets its 
commitment within the applicable time frame, however, EPA would 
subsequently publish a notice in the Federal Register notifying the 
public that EPA intends to take final action to approve or disapprove 
the State's revised regulations. If EPA were to approve the revised 
regulations, the regulations would be fully approved in their entirety 
and replace the conditionally approved provisions of the State's SIP 
regulations. Finally, EPA is proposing to fully approve the definitions 
at PART Env-A 101.174 ``Minor permit amendment'' and PART Env-A 101.262 
``State permit to operate'' submitted to EPA on July 21, 2003.

VIII. Incorporation by Reference

    In this rule, the EPA is proposing to include in a final EPA rule 
regulatory text that includes incorporation by reference. In accordance 
with requirements of 1 CFR 51.5, EPA is proposing to incorporate by 
reference the following NH DES rules: the PSD rules at PART Env-A 619, 
``Prevention of Significant Deterioration'' (originally proposed on 
January 21, 2015) as discussed in Section IV of the preamble; the NNSR 
rules at PART Env-A 618, ``Nonattainment New Source Review'' discussed 
in Section V of the preamble; and the definitions for ``minor permit 
amendment'' and ``state permit to operate'' under PART Env-A 101, 
``Permit Definitions'' as discussed in section VI of the preamble. EPA 
has made, and will continue to make, these documents generally 
available electronically through www.regulations.gov and/or in hard 
copy at the U.S. Environmental Protection Agency, EPA New England 
Regional Office, Office of Ecosystem Protection, Air Permits, Toxics 
and Indoor Programs Unit, 5 Post Office Square--Suite 100, (mail code 
OEP05-2), Boston, MA 02109-3912

IX. Statutory and Executive Order Reviews

    Under the Clean Air Act, the Administrator is required to approve a 
SIP submission that complies with the provisions of the Act and 
applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). 
Thus, in reviewing SIP submissions, EPA's role is to approve state 
choices, provided that they meet the criteria of the Clean Air Act. 
Accordingly, this proposed action merely approves state law as meeting 
Federal requirements and does not impose additional requirements beyond 
those imposed by state law. For that reason, this proposed action:
     is not a ``significant regulatory action'' subject to 
review by the Office of Management and Budget under Executive Order 
12866 (58 FR 51735, October 4, 1993);
     does not impose an information collection burden under the 
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
     is certified as not having a significant economic impact 
on a

[[Page 22964]]

substantial number of small entities under the Regulatory Flexibility 
Act (5 U.S.C. 601 et seq.);
     does not contain any unfunded mandate or significantly or 
uniquely affect small governments, as described in the Unfunded 
Mandates Reform Act of 1995 (Public Law 104-4);
     does not have Federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 10, 1999);
     is not an economically significant regulatory action based 
on health or safety risks subject to Executive Order 13045 (62 FR 
19885, April 23, 1997);
     is not a significant regulatory action subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001);
     is not subject to requirements of Section 12(d) of the 
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 
note) because application of those requirements would be inconsistent 
with the Clean Air Act; and
     does not provide EPA with the discretionary authority to 
address, as appropriate, disproportionate human health or environmental 
effects, using practicable and legally permissible methods, under 
Executive Order 12898 (59 FR 7629, February 16, 1994).
    In addition, this rule does not have tribal implications as 
specified by Executive Order 13175 (65 FR 67249, November 9, 2000), 
because the SIP is not approved to apply in Indian country located in 
the state, and EPA notes that it will not impose substantial direct 
costs on tribal governments or preempt tribal law.
