Approval and Promulgation of Air Quality Implementation Plans; 
New Hampshire; New Source Review Revision

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rule.

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

SUMMARY: EPA is approving State Implementation Plan (SIP) revisions 
submitted by the State of New Hampshire. The revisions establish and 
require the implementation of the Clean Air Act Amendments (CAAA) of 
1990 regarding New Source Review (NSR) in areas that have not attained 
the National Ambient Air Quality Standards (NAAQS) and areas within the 
ozone transport region (OTR). In addition, the revisions replace the 
existing definition of stationary source in New Hampshire's SIP with 
the plantwide stationary source definition. The intended effect of this 
action is to approve PART Env-A 610, ``Additional Requirements in 
Nonattainment Areas and the New Hampshire Portion of the Northeast 
Ozone Transport Region.'' This action is being taken in accordance with 
the Clean Air Act (CAA).

DATES: This direct final rule is effective on September 25, 2001 
without further notice, unless EPA receives adverse comment by August 
27, 2001. If adverse comments are received, EPA will publish a timely 
withdrawal of the direct final rule in the Federal Register and inform 
the public that the rule will not take effect.

ADDRESSES: Comments may be mailed to Steven Rapp, Unit Manager, Air 
Permits Program, Office of Ecosytem Protection (mail code CAP), U.S. 
Environmental Protection Agency, EPA New England, One Congress Street, 
Suite 1100, Boston, MA 02114-2023. Copies of the documents relevant to 
this action are available for public inspection during normal business 
hours, by appointment at the Office of Ecosytem Protection, U.S. 
Environmental Protection Agency, Region I, One Congress Street, 11th 
floor, Boston, MA, and New Hampshire Department of Environmental 
Services, 6 Hazen Drive, P.O. Box 95, Concord, NH 03302-0095.

SUPPLEMENTARY INFORMATION:

I. Background

    On July 29, 1993, New Hampshire Air Resources Division (ARD) 
formally submitted a revision to its State Implementation Plan (SIP) 
for purposes of meeting the requirements of the CAA. The revision 
consists of changes to New Hampshire's PART Env-A 610, ``Additional 
Requirements in Nonattainment Areas and the New Hampshire Portion of 
the Northeast Ozone Transport Region.'' The revision did not include 
provisions to implement two requirements of the CAA, the

[[Page 39101]]

adequate SIP implementation requirement under section 173(a)(4) and the 
alternative siting analysis requirement under section 173(a)(5). On 
July 2, 1999, the ARD submitted additional changes to PART Env-A 610 
(renumbered as Env-A 622) that met the requirements of sections 
173(a)(4) and 173(a)(5) of the CAA. With the inclusion of the two 
missing provisions, the ARD's rules regarding the permitting of new 
major sources in nonattainment areas and the OTR are consistent with 
all CAA NSR requirements. In addition, the ARD's July 2, 1999 SIP 
revision removed the dual source definition of stationary source and 
adopted a plant-wide stationary source definition consistent with 
federal requirements.
    Please note that if EPA receives adverse comment on an amendment, 
paragraph, or section of this rule and if that provision may be severed 
from the remainder of the rule, EPA may adopt as final those provisions 
of the rule that are not the subject of an adverse comment.

A. General Requirements for Nonattainment NSR

Background
    The air quality planning requirements for nonattainment NSR are set 
out in part D of subpart I of Title I of the Act. The EPA has issued a 
``General Preamble'' describing EPA's preliminary views on how EPA 
intends to review SIPs and SIP revisions submitted under part D, 
including those State submittals containing nonattainment area NSR SIP 
requirements. See 57 FR 13498 (April 16, 1992) and 57 FR 18070 (April 
28, 1992). Because EPA is describing its interpretations here only in 
broad terms, the reader should refer to the General Preamble and the 
January 25, 2001 Technical Support Document entitled, ``New Hampshire 
New Source Review Revisions,'' located at the addresses listed above 
for a more detailed discussion of the interpretations of part D 
advanced in today's proposal and the supporting rationale.

Summary of New Hampshire's Regulation

    The general nonattainment NSR requirements are found in sections 
172 and 173 of part D and must be met by all nonattainment areas. The 
following paragraphs reference the nonattainment NSR requirements 
required to be submitted to EPA by November 15, 1992 and explain how 
New Hampshire's rules meet those requirements. New Hampshire's existing 
SIP already contained some of these provisions, while others are being 
approved today.
    1. New Hampshire regulation Env-A 610.05(d) establishes provisions 
in accordance with section 173(a)(1)(A) of the CAA to assure that 
calculations of emissions offsets are based on the same emissions 
baseline used in the demonstration of Reasonable Further Progress 
(RFP).
    2. New Hampshire regulation Env-A 610.05(c) establishes provisions 
in accordance with section 173(c)(1) of the CAA to allow offsets to be 
obtained in another nonattainment area if: (i) The area has an equal or 
higher nonattainment classification and, (ii) emissions from the other 
nonattainment area contribute to an NAAQS violation in the area in 
which the source would construct.
    3. New Hampshire regulation Env-A 610.05 (c)(5)c. establishes 
provisions in accordance with section 173(c)(1) of the CAA that any 
emissions offsets obtained in conjunction with the issuance of a 
license to a new or modified source must be in effect and enforceable 
by the time the new or modified source commences operation.
    4. New Hampshire regulation Env-A 610.05(a) establishes provisions 
in accordance with section 173(c)(1) of the CAA to assure that emission 
increases from new or modified sources are offset by real reductions in 
actual emissions.
    5. New Hampshire regulations Env-A 610.05(b)(2) and (3) establish 
provisions in accordance with section 173(c)(2) of the CAA to prevent 
emissions reductions otherwise required by the Act from being credited 
for purposes of satisfying part D offset requirements.
    6. The 1990 CAAA modified the Act's provisions on growth allowances 
in nonattainment areas by (1) eliminating existing growth allowances in 
the nonattainment area that received a notice prior or subsequent to 
the Amendments that the SIP was substantially inadequate, and (2) 
restricting growth allowances to only those portions of nonattainment 
areas formally targeted as special zones for economic growth. Sections 
173(b) and 173(a)(1)(B) of the CAA. New Hampshire's regulations do not 
contain provisions for growth allowances and are consequently 
consistent with the Act.
    7. New Hampshire has a practice of supplying information to EPA's 
RACT/BACT/LAER clearinghouse in accordance with section 173(d) of the 
CAA.
    8. New Hampshire regulation Env-A 610.04(b) establishes provisions, 
in accordance with section 173(a)(3) of the CAA, to assure that owners 
or operators of each proposed new or modified major stationary source 
demonstrate, as a condition of license issuance, that all other major 
stationary sources under the same ownership in the State are in 
compliance with the CAA.
    9. New Hampshire regulation Env-A 622.04 establishes provisions in 
accordance with 173(a)(5) of the CAA that, as a prerequisite to issuing 
any part D license, require an analysis of alternative sites, sizes, 
production processes, and environmental control techniques for the 
proposed source that demonstrates that the benefits of the proposed 
source significantly outweigh the environmental and social costs 
imposed as a result of its location, construction, or modification.
    10. New Hampshire regulation Env-A 622.06 establishes provisions in 
accordance to section 173(a)(4) of the CAA that require as a 
prerequisite to issuing a part D permit, the Administrator has not 
determined that the applicable implementation plan is not being 
adequately implemented for the nonattainment area in which the proposed 
source is to be constructed or modified.

B. General Requirements for Ozone Nonattainment NSR and the OTR

Background
    The general nonattainment NSR requirements are found in sections 
172 and 173 of part D and must be met by all nonattainment areas. The 
requirements for ozone that supplement or supersede these requirements 
are found in subpart 2 of part D. In addition to requirements for ozone 
nonattainment areas, subpart 2 includes section 182(f), which states 
that requirements for major stationary sources of VOC shall apply to 
major stationary sources of oxides of nitrogen ( NOX) unless 
the Administrator makes certain determinations related to the benefits 
or contribution of NOX control to air quality, ozone 
attainment, or ozone air quality. States were required under section 
182(a)(2)(C) to adopt new NSR rules for ozone nonattainment areas by 
November 15, 1992.
    Pursuant to sections 172(c)(5) of the CAA, State implementation 
plans must require permits for the construction and operation of new or 
modified major stationary sources in nonattainment areas. The federal 
statutory permit requirements for ozone nonattainment areas are 
generally contained in revised section 173, and in subpart 2 of 
Subchapter I, part D of the CAA. These are the minimum requirements 
that States must include in an approvable implementation plan. For all 
classifications of ozone nonattainment areas and for ozone transport 
regions

[[Page 39102]]

(OTRs), States must adopt the appropriate major source thresholds and 
offset ratios, and must adopt provisions to ensure that any new or 
modified major stationary source of NOX satisfies the 
requirements applicable to any major source of VOC, unless a special 
NOX exemption is granted by the Administrator under the 
provision of section 182(f). For serious and severe ozone nonattainment 
areas, State plans must implement section 182(c)(6) with regard to 
modifications of major sources.

Summary of New Hampshire's Submittal

    The State of New Hampshire currently contains serious, marginal and 
nonclassified nonattainment areas, as well as areas classified as 
attainment. In addition, the entire State is contained within the OTR 
(see section 184 of the CAA). The CAA provisions that apply to the OTR 
provide equal or more stringent requirements than those provisions 
applicable to the marginal and moderate nonattainment areas. Under the 
CAA, the OTR provisions are applicable throughout the State.
    The following paragraphs reference the serious ozone nonattainment 
and OTR NSR requirements that New Hampshire was required to submit to 
EPA by November 15, 1992 and how New Hampshire has met those 
requirements. To identify those areas of New Hampshire that are within 
the more stringent serious ozone nonattainment area, New Hampshire's 
regulations establish a definition for the Four-County Ozone Classified 
Nonattainment Region. This region includes the counties of 
Hillsborough, Merrimack, Rockingham and Strafford and encompasses the 
geographic area classified as a serious nonattainment area as 
designated by the EPA within Section 107 of the CAA. All regions 
outside the four-county ozone classified nonattainment region are 
subject to the federal NSR requirements for the OTR.

NSR Requirements for the Ozone Transport Region

    1. New Hampshire regulation Env-A 610.01(a)(2)b.1. establishes, in 
accordance with the OTR requirements provided in section 184(b)(2) of 
the CAA, a major source threshold level of 50 TPY for VOC for the 
entire state.
    2. New Hampshire regulation Env-A 610.01(a)(2)b.2.ii. establishes, 
in accordance with sections 184(b)(2), 182(f) and 302(j) of the CAA, a 
major source threshold level of 100 tpy for NOX for sources 
located outside the four-county ozone nonattainment region. This major 
source threshold level satisfies the OTR NSR requirements.
    3. New Hampshire regulation Env-A 610.05(c)(1)b. of New Hampshire's 
regulation establishes, in accordance with sections 184(b)(2), 
182(b)(5) and 182(f) of the CAA, an offset ratio of 1.15 to 1 for major 
sources or major modifications to major sources of VOC and 
NOX outside the four-county ozone nonattainment area. This 
offset ratio satisfies the federal OTR NSR Federal requirement.

Serious Ozone Nonattainment Areas

    1. New Hampshire regulation Env-A 610.01(a)(2)b.1. establishes, in 
accordance to the serious nonattainment area requirements provided in 
section 182(c) of the CAA, a major source threshold level of 50 TPY for 
VOC for the entire state.
    2. New Hampshire regulation Env-A 610(a)(2)b.2.i establishes, in 
accordance with sections 182(c) and 182(f) of the CAA, a major 
stationary source threshold of 50 TPY for NOX in the four-
county ozone classified nonattainment region.
    3. New Hampshire regulation Env-A 610.05(c)(1)a. establishes, in 
accordance with sections 182(c)(10) and 182(f) of the CAA, an offset 
ratio of 1.2 to 1 for major sources or major modifications of VOC or 
NOX in the four-county ozone classified nonattainment 
region.
    4. New Hampshire regulations Env-A 610.03(e)(1) and 610.03(f)(1) 
establish provisions that are consistent with the requirements of 
section 182(c)(6) of the CAA, the ``De Minimis rule.''

C. Revisions to Stationary Source Definition

Background
    On August 7, 1980 (45 FR 52676), EPA promulgated a rule defining a 
``stationary source'' as ``any building, structure, facility, or 
installation.'' Known as the ``dual source definition,'' a stationary 
source is both a building structure or facility and an installation 
(e.g., an individual piece of equipment). For NSR applicability, 
permitting authorities consider each emission unit as a separate 
independent stationary source and as a component of the entire 
stationary source. Emission increases from a physical or operational 
changes at an emission unit are reviewed both with and without regard 
to reductions elsewhere in the plant. Consequently, with respect to NSR 
applicability, the dual source definition does not offer any benefits 
to sources that reduce emissions at emission units not undergoing 
modification. On October 14, 1981 (46 FR 50766), EPA revised its NSR 
regulations to allow adoption of a ``plantwide'' definition. Under this 
definition, sources determining major NSR applicability of a proposed 
modification are not required to consider each emission unit as an 
individual stationary source. Consequently, the plantwide definition 
provides sources the opportunity to take credit for emissions 
reductions achieved across the entire facility when determining NSR 
applicability for modifications occurring at individual emission 
unit(s).

Summary of New Hampshire's Submittal

    New Hampshire is revising its stationary source definition in Env-A 
622-01 to make the definition consistent with EPA's plantwide 
definition of stationary source as adopted in EPA's NSR regulations 
under 40 CFR 51.165(a)(1).
    General Savings Clause. The ARD's adoption of plantwide source 
definition revises a regulation that was in effect before the enactment 
of the CAAA of 1990. Pursuant to Section 193 of the Clean Air Act, the 
``general savings clause,'' EPA must determine whether this revision to 
New Hampshire's NSR Program ensures equivalent or greater reductions of 
nonattainment area pollutants. In conducting this analysis, EPA 
examines the impact of all revisions to New Hampshire's SIP since 1990. 
The analysis found that New Hampshire's SIP revisions made since 1990 
will ensure equivalent or greater emissions reductions as compared with 
New Hampshire SIP in effect as of 1990.
    To determine the impact of New Hampshire's revision to its source 
definition, EPA considered the potential increase in emissions from 
sources modifying their facilities. Typically, the change from the dual 
source definition to plantwide source definition may allow more sources 
with modifications to ``net out'' of major NSR applicability. However, 
determining how many additional modifications would ``net out'' due to 
the revision is difficult. The NSR rules contain numerous complex 
applicability provisions that all work together in determining if a new 
source is subject to NSR. However, in reviewing past permit 
transactions completed under New Hampshire's old dual source 
definition, EPA did not identify any modifications that triggered major 
NSR review. The review suggests that the number of modifications 
potentially effected by the ARD's source definition revision is 
relatively small and that the impact to the State's overall emissions 
would also be small.

[[Page 39103]]

    To offset the relatively small increase in emissions from the 
revision, EPA considered other revisions approved into New Hampshire 
since 1990 that strengthen its SIP. On November 14, 2000, EPA approved 
the ARD's Order 98-001 into the SIP. The order requires Public Service 
of New Hampshire (PSNH) to meet by 1999 a yearly emissions cap that 
significantly reduces emissions from their facilities in New Hampshire. 
A significant portion of these emission reductions, over a thousand 
tons per year, are surplus reductions not required by any CAA 
requirement. These surplus reductions more than offset any potential 
emission increase resulting from DES's revisions to their stationary 
source definition.
    In summation, EPA concludes that the overall effect of New 
Hampshire's revised SIP will ensure reductions equivalent to those 
obtained in the existing SIP. EPA understands that the plantwide 
definition revision will effect a small number of sources and may cause 
a slight increase in State's emissions. However, EPA believes the ARD's 
PSNH order strengthens the SIP and provides surplus emission decreases 
not required by the CAA. These surplus emission reductions more than 
offset the emission increases from the new source definition revision.

II. Final Action

    EPA is approving the revisions to New Hampshire's PART Env-A 610 
(renumbered to Env-A 622), ``Additional Requirements in Nonattainment 
Areas and the New Hampshire Portion of the Northeast Ozone Transport 
Region.'' The Agency has reviewed this request for revision of the 
Federally-approved State implementation plan for conformance with the 
provisions of the 1990 amendments enacted on November 15, 1990. These 
revisions meet the nonattainment area NSR provisions of Part D of the 
CAA.
    EPA is publishing this rule without prior proposal because the 
Agency views this as a noncontroversial amendment and anticipates no 
adverse comments. However, in the proposed rules section of this 
Federal Register publication, EPA is publishing a separate document 
that will serve as the proposal to approve the SIP revision should 
relevant adverse comments be filed. This action will be effective 
September 25, 2001 without further notice unless the Agency receives 
relevant adverse comments by August 27, 2001.
    If the EPA receives such comments, then EPA will publish a document 
withdrawing the final rule and informing the public that the rule will 
not take effect. All public comments received will then be addressed in 
a subsequent final rule based on the proposed rule. The EPA will not 
institute a second comment period. Parties interested in commenting 
should do so at this time. If no such comments are received, the public 
is advised that this rule will be effective on September 25, 2001 and 
no further action will be taken on the proposed rule.

III. Administrative Requirements

    Under Executive Order 12866 (58 FR 51735, October 4, 1993), this 
action is not a ``significant regulatory action'' and therefore is not 
subject to review by the Office of Management and Budget. This action 
merely approves state law as meeting federal requirements and imposes 
no additional requirements beyond those imposed by state law. 
Accordingly, the Administrator certifies that this rule will not have a 
significant economic impact on a substantial number of small entities 
under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.). Because 
this rule approves pre-existing requirements under state law and does 
not impose any additional enforceable duty beyond that required by 
state law, it 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). This rule also does not 
have a substantial direct effect on one or more Indian tribes, on the 
relationship between the Federal Government and Indian tribes, or on 
the distribution of power and responsibilities between the Federal 
Government and Indian tribes, as specified by Executive Order 13175 (65 
FR 67249, November 9, 2000), nor will it 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 Executive Order 13132 (64 FR 43255, August 10, 1999), because it 
merely approves a state rule implementing a federal standard, and does 
not alter the relationship or the distribution of power and 
responsibilities established in the Clean Air Act. This rule also is 
not subject to Executive Order 13045 (62 FR 19885, April 23, 1997), 
because it is not economically significant.
    In reviewing SIP submissions, EPA's role is to approve state 
choices, provided that they meet the criteria of the Clean Air Act. In 
this context, in the absence of a prior existing requirement for the 
State to use voluntary consensus standards (VCS), EPA has no authority 
to disapprove a SIP submission for failure to use VCS. It would thus be 
inconsistent with applicable law for EPA, when it reviews a SIP 
submission, to use VCS in place of a SIP submission that otherwise 
satisfies the provisions of the Clean Air Act. Thus, the requirements 
of section 12(d) of the National Technology Transfer and Advancement 
Act of 1995 (15 U.S.C. 272 note) do not apply. As required by section 3 
of Executive Order 12988 (61 FR 4729, February 7, 1996), in issuing 
this rule, EPA has taken the necessary steps to eliminate drafting 
errors and ambiguity, minimize potential litigation, and provide a 
clear legal standard for affected conduct. EPA has complied with 
Executive Order 12630 (53 FR 8859, March 15, 1988) by examining the 
takings implications of the rule in accordance with the ``Attorney 
General's Supplemental Guidelines for the Evaluation of Risk and 
Avoidance of Unanticipated Takings'' issued under the executive order. 
This rule does not impose an information collection burden under the 
provisions of the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et 
seq.).
    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. EPA will submit a report containing this rule and other 
required information to the U.S. Senate, the U.S. House of 
Representatives, and the Comptroller General of the United States prior 
to publication of the rule in the Federal Register. A major rule cannot 
take effect until 60 days after it is published in the Federal 
Register. This action is not a ``major rule'' as defined by 5 U.S.C. 
804(2).
    Under section 307(b)(1) of the Clean Air Act, petitions for 
judicial review of this action must be filed in the United States Court 
of Appeals for the appropriate circuit by September 25, 2001. 
Interested parties should comment in response to the proposed rule 
rather than petition for judicial review, unless the objection arises 
after the comment period allowed for in the proposal. Filing a petition 
for reconsideration by the Administrator of this final rule does not 
affect the finality of this rule for the purposes of judicial review 
nor does it extend the time within which a petition for judicial review 
may be filed, and shall not postpone the effectiveness of such rule or 
action. This action may not be challenged later in proceedings to

[[Page 39104]]

enforce its requirements. (See section 307(b)(2).)
