[EPA-R09-OAR-2013-0697; FRL-9902-75-Region 9]


Approval and Promulgation of Implementation Plans; Commonwealth 
of the Northern Mariana Islands; Prevention of Significant 
Deterioration; Special Exemptions From Requirements of the Clean Air 
Act

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: Under the Clean Air Act, EPA is proposing to disapprove the 
state implementation plan (SIP) for the Commonwealth of the Northern 
Mariana Islands (CNMI) with respect to prevention of significant 
deterioration (PSD), and to incorporate by reference the Federal PSD 
regulations into the applicable CNMI plan. EPA is also proposing to 
approve a petition by CNMI for an exemption of the applicable PSD major 
source baseline date and trigger date under Federal PSD regulations, 
and to establish an alternate date, January 13, 1997, as the major 
source baseline date and trigger date in CNMI. EPA is also proposing to 
make certain corrections that were made in previous rulemakings. This 
action would establish the Federal PSD regulations as a basic element 
of the CNMI implementation plan and, through the exemption, would 
establish January 13, 1997 as the major source baseline date (and 
trigger date) under the PSD program in CNMI for sulfur dioxide, 
PM10 and nitrogen dioxide.

I. Prevention of Significant Deterioration

A. Background

    Under the Clean Air Act (CAA or ``Act''), as amended in 1970, EPA 
established the first national ambient air quality standards (NAAQS or 
``standard''), which represent standards EPA has determined are 
requisite to protect the public health and welfare. Once EPA has 
established a NAAQS, under CAA section 110(a), each state is required 
within a prescribed period of time to adopt and submit a plan, referred 
to as the State Implementation Plan (SIP), which provides for 
implementation, maintenance, and enforcement of such NAAQS. Under the 
Clean Air Amendments of 1970, the term ``state'' was defined in section 
302(d) as meaning one of the 50 States, the District of Columbia, the 
Commonwealth of Puerto Rico, the Virgin Islands, Guam, and American 
Samoa. The Commonwealth of the Northern Mariana Islands (CNMI) was not 
included within the meaning of ``state'' under the 1970 Amended Act.\1\ 
At the time of the 1970 Act Amendments, CNMI was part of the post-World 
War II United Nations' Trust Territory of the Pacific Islands (TPPI). 
In 1976, Congress approved the mutually negotiated Covenant to 
Establish a Commonwealth of the Northern Mariana Islands (CNMI) in 
Political Union with the United States.
---------------------------------------------------------------------------

    \1\ CNMI consists of 15 islands of volcanic origin which are 
located approximately 145[deg] to 146[deg] east and from 14[deg] to 
20[deg] north of the equator. The islands extend in a general north-
south direction for approximately 420 nautical miles from the Island 
of Farallon de Pajaros in the north to the island of Rota in the 
south. CNMI lies in the western part of the Pacific Ocean and is 
located approximately 1,250 miles south of Tokyo, 1,440 miles east 
of Manila, and 110 miles north of Guam. Based on Bureau of Census 
2010 population counts, the total population of CNMI is 
approximately 54,000 with the majority of the population residing on 
Saipan.
---------------------------------------------------------------------------

    Generally speaking, SIPs must include a number of substantive 
elements including, but not limited to, rules establishing emission 
limitations, permit programs for new or modified major stationary 
sources (``New Source Review,'' or NSR), programs for monitoring 
ambient air concentrations, and necessary assurances that the State has 
adequate legal authority and resources to implement the SIP.
    Once a SIP is submitted, EPA must take action to approve or 
disapprove it, in whole or in part. If, however, a state fails to 
submit a SIP or a portion of the SIP, or if EPA disapproves a SIP or 
portion of the SIP, then generally speaking, EPA must promulgate a 
Federal Implementation Plan (FIP) to address the plan deficiency. 
Together, the approved portions of the SIP and EPA's FIP for a given 
state constitute that state's applicable plan for the purposes of the 
CAA. See 40 CFR 52.02(b). Each state's applicable plan is listed in 
separate subparts of 40 CFR part 52. For example, the applicable CNMI 
plan is found in subpart FFF of 40 CFR part 52.
    One of the SIP content requirements under section 110 is the 
requirement to prevent significant deterioration of air quality (PSD) 
in areas that are meeting the NAAQS through review and permitting of 
new major stationary sources and major modifications. As such, PSD is a 
specific type of NSR program. The federal PSD program began in the 
early 1970's during which EPA reviewed each SIP, determined that the 
SIPs generally did not contain regulations or procedures specifically 
addressing PSD, and thus disapproved all of the SIPs to the extent they 
lacked procedures and regulations for preventing significant 
deterioration of air quality in portions of the state where air quality 
is better than one or more the NAAQS. 37 FR 23836 (November 9, 1972).
    In 1974, EPA promulgated a PSD FIP (then, and now, codified in 40 
CFR 52.21) to apply in all states for which EPA had disapproved the SIP 
with respect to PSD. 39 FR 42510 (December 5, 1974). In our 1974 final 
rule, we retained (as 40 CFR 52.21(a)) our 1972 general disapproval 
statement for all SIPs with respect to PSD. In June 1975, EPA modified 
part 52 by incorporating specific PSD disapprovals into the applicable 
subpart for each state in part 52, and EPA modified the general 
disapproval statement of section 52.21(a) accordingly. EPA indicated 
that these changes to each subpart had no substantive effect but were 
rather made so that all regulations applicable to a particular 
implementation plan would be located in one place. 40 FR 25004 (June 
12, 1975).
    On August 7, 1977, the CAA Amendments of 1977 became law. The 1977 
Amendments changed the 1970 CAA and EPA's regulations in many respects, 
particularly with regard to PSD. In addition to mandating certain 
immediately effective changes to EPA's PSD regulations, the 1977 
Amendments, in sections 160-169 (i.e., subpart I of part C 
(``Prevention of Significant Deterioration of Air Quality'') of title 
I), contained comprehensive new PSD requirements. These new 
requirements were to be incorporated by States into their respective 
SIPs (under section 110 of the CAA). The 1977 Amendments also revised 
the definition of the term, ``state,'' in CAA section 302(d), to 
include CNMI, in recognition of the change during the 1970s in the 
relationship between CNMI and United States. CNMI did not become 
subject to the CAA, however, until January 9, 1978.\2\ On March 3, 1978 
(43 FR 8962), EPA established the first area designations under CAA 
section 107 and thereby divided the states into areas designated as 
nonattainment, attainment

[[Page 70250]]

or unclassifiable with respect to each of the various NAAQS. In so 
doing, EPA designated CNMI as attainment or unclassifiable/attainment 
for each of the NAAQS, and CNMI continues to be so designated. See 40 
CFR 81.354.
---------------------------------------------------------------------------

    \2\ CNMI is an insular territory of the United States. The 
relations between CNMI and the United States are governed by the 
Covenant to Establish a Commonwealth of the Northern Mariana Islands 
in Political Union with the United States of America (``Covenant''). 
See 48 U.S.C. 1801 notes. Section 502 of the Covenant lists laws 
which are in existence on the effective date of section 502 and 
states that these laws and the subsequent amendments to such laws 
will apply to CNMI, unless otherwise specified in the Covenant. 
Paragraph (1) of section 502 lists federal banking laws, provisions 
of the Social Security Act and the Public Health Service Act. 
Paragraph (2) states ``those laws not described in paragraph (1) 
which are applicable to Guam and which are of general application to 
the several States as they are applicable to the several States.'' 
Proclamation No. 4534, signed by President Carter in 1977, states in 
section 2 that section 502 of the Covenant came into effect on 
January 9, 1978. See 42 FR 56593. As noted above, Guam has been 
included in the term ``state'' for CAA purposes since the 1970 
Amended Act.
---------------------------------------------------------------------------

    In June 1978, in response to the CAA Amendments of 1977, and again 
in August 1980, in response to litigation, EPA revised the PSD 
requirements for SIPs in 40 CFR 51.24 (renumbered later as 40 CFR 
51.166) and the Federal PSD regulations in 40 CFR 52.21. See 43 FR 
26380 and 26388 (June 19, 1978), and 45 FR 52676 (August 7, 1980). At 
the time these revisions were promulgated, CNMI had not submitted a 
SIP, and there was no subpart within part 52 addressing the approval 
status of CNMI. When EPA specified the states which did not meet the 
new PSD requirements, CNMI was not listed. See 43 FR 26388, at 26410, 
and 45 FR 52676, at 52741.
    Thus, while the CAA, including the PSD requirements in subpart I to 
part C of title I, has applied to sources on CNMI since January 9, 
1978, EPA's PSD regulations in 40 CFR 52.21 that implement the 
statutory PSD program have not been incorporated into the applicable 
plan for CNMI. This has lead to uncertainty as to the proper 
application of PSD to new major sources or major modifications on CNMI.
    On February 19, 1986, CNMI submitted their air pollution control 
regulations, including rules governing NSR. Later that year, CNMI 
revised the regulations and re-submitted them on February 19, 1987. On 
November 13, 1987 (52 FR 43574), EPA approved the NSR-related rules as 
part of the CNMI SIP. In taking this action, EPA noted that approval of 
the CNMI rules was not to be construed as indicating satisfaction of 
the specific requirements for PSD. See 52 FR 43574.
    Since the most recent approval of the CNMI SIP in 1987, under CAA 
sections 108 and 109, EPA has conducted periodic reviews of the NAAQS 
and has, in recent years, established certain new or revised NAAQS. As 
noted above, under section 110(a), States must submit a plan that 
provides for implementation, maintenance, and enforcement of such 
NAAQS. The CAA directs EPA to make findings of failure to submit (such 
a plan or portion of a plan) if a plan or portion of a plan is not 
forthcoming from the State. EPA has made such findings for certain new 
or revised NAAQS with respect to CNMI.
    In March 2008, EPA published a finding of failure to submit with 
respect to the 1997 8-hour ozone NAAQS for a number of states, 
including CNMI. 73 FR 16205 (March 27, 2008). EPA's March 2008 finding 
relates to the SIP elements listed in CAA section 110(a)(2), including 
failure to submit a SIP addressing section 110(a)(2)(C) (the Part C PSD 
permit program) for the 1997 8-hour ozone NAAQS. Later that year, we 
made a similar finding with respect to CNMI and the 1997 
PM2.5 NAAQS. 73 FR 62902 (October 22, 2008). In 2010, we 
found that CNMI had failed to submit a SIP revision addressing 
interstate transport requirements with respect to the 2006 
PM2.5 NAAQS. 75 FR 32673 (June 9, 2010). Under section 
110(a)(2)(D), the SIP submittal requirements related to interstate 
transport also implicate PSD. These findings of failure to submit 
created two-year deadlines for EPA to promulgate FIPs unless, prior to 
that deadline, CNMI makes submissions to meet the requirements and EPA 
approves such submissions. See section 110(c)(1). No submittals have 
been forthcoming from CNMI, and the two-year FIP deadlines have 
expired.

B. EPA's Evaluation of the CNMI SIP and Proposed Action

    The basic purpose of the PSD program is to prevent significant 
deterioration by protecting the NAAQS and ``increments'' over the 
baseline concentration in areas designated as attainment or 
unclassifiable, through a permit program for new major sources and 
major modifications to major sources. Requirements for SIPs with 
respect to PSD are found primarily in 40 CFR 51.166.
    Under 40 CFR 51.166, each state must adopt and submit rules that: 
Establish certain ambient air increments and ambient air ceilings (40 
CFR 51.166(c) and (d)); establish certain area classifications (i.e., 
class I, II, or III) and restrict certain types of area 
reclassifications (40 CFR 51.166(e) and (g)); limit the reliance on 
stack height in determining the degree of emission limitation (40 CFR 
51.166(h)); provide for certain control technology review, including 
the application of best available control technology (BACT) for each 
regulated NSR pollutant that a new major source or major modification 
would have the potential to emit in significant amounts (40 CFR 
51.166(j)); provide for certain source impact analyses (40 CFR 
51.166(k)); require use of EPA-approved air quality models (40 CFR 
51.166(l)); provide for certain preapplication and post-construction 
air quality analyses and monitoring (40 CFR 51.166(m)); establish 
certain permit application requirements (40 CFR 51.166(n)); provide for 
certain additional impact analyses (e.g., visibility impact analyses) 
(40 CFR 51.166(o)); establish certain additional requirements for 
sources impacting Federal Class I area (40 CFR 51.166(p)); provide for 
public participation (40 CFR 51.166(q)); impose certain source 
obligations (40 CFR 51.166(r)); and establish provision for plantwide 
applicability limitations (PALs) (40 CFR 51.166(w)). The PSD SIP 
requirements listed above rely on certain terms, including ``major 
stationary source,'' ``major modification,'' ``net emissions 
increase,'' and many others, that are defined specifically for use in 
the PSD program. See 40 CFR 51.166(b).
    We reviewed the NSR portion of the CNMI SIP, which includes Parts V 
and X of the ``CNMI Air Pollution Control Regulations'' that EPA 
approved on November 13, 1987 (52 FR 43574). Under Part V of CNMI's 
rules, permits are required for the construction and operation of all 
new sources or modifications of major sources of emissions. The NSR 
rules also provide for certain exemptions from the permit requirement; 
provide for certain application requirements; establish a process for 
review by the CNMI Division of Environmental Quality (DEQ) of permit 
applications; authorize DEQ to impose certain types of permit 
conditions and to require applicants to conduct certain additional 
analyses (e.g., performance testing); disallow the use of dispersion 
techniques as a form of controlling air pollution absent EPA exemption; 
and address administrative matters such as permit suspension, permit 
transfer, and permit posting, among other such matters. Part X of 
CNMI's rules provide for public participation prior to approval of an 
application for an NSR permit for a major source. Under CNMI's NSR 
rules, DEQ will approve an NSR permit application if the applicant can 
show to DEQ's satisfaction that: (1) The new source is designed, built 
and equipped with reasonably available control technology (RACT); (2) 
the new source is designed and will be constructed or modified to 
operate without causing a violation of the applicable rules and 
regulations; and (3) the new source will not endanger the maintenance 
or attainment of the NAAQS or ambient air increments as set forth as 
Maximum Allowable Increases for Class II areas for sulfur dioxide and 
particulate matter in 40 CFR 52.21(c) and (d).
    Our review of the CNMI SIP NSR rules reveals that some aspects of 
the PSD program required under 40 CFR 51.166 are met, such as the 
establishment of certain ambient air increments (i.e., increments for 
sulfur dioxide) and ambient air ceilings (i.e., the NAAQS) that 
concentrations of pollutants resulting from construction of

[[Page 70251]]

new major sources and major modifications may not exceed; provisions 
limiting use of stack height and other dispersion techniques; and 
certain provisions for public participation (e.g., notice in newspaper 
of general circulation, and 30-day comment period). However, CNMI's NSR 
rules do not meet many other PSD requirements, including, e.g., 
establishment of ambient air increments for nitrogen dioxide, 
PM10 and PM2.5; provisions requiring application 
of BACT; provisions requiring use of EPA-approved air quality models; 
and provisions allowing establishment of PALs. Moreover, many of the 
definitions of NSR-related terms in CNMI's rules, e.g., ``major 
stationary source'' and ``major modification,'' differ from the 
corresponding definitions in 40 CFR 51.166(b). Under 40 CFR 51.166(b), 
deviations in the wording relative to the definition set forth in the 
Federal PSD regulations 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 EPA 
definition. Therefore, we propose to disapprove the CNMI SIP as not 
meeting the requirements for PSD under part C of title I of the CAA and 
40 CFR 51.166.
    Based on our determination that the current CNMI SIP does not meet 
the requirements for PSD, EPA is also proposing to apply the Federal 
PSD program at 40 CFR 52.21 to CNMI, but to grant the petition of CNMI 
for exemption from the original major source baseline date, as 
described in the following section of this document. EPA would 
administer the PSD program for CNMI and would make PSD determinations 
and issue PSD permits directly from the EPA Region IX office. In the 
future, if requested, EPA would consider delegation of implementation 
authority to CNMI under 40 CFR 52.21(u).
    Applying the Federal PSD program to CNMI would address long-
standing uncertainties concerning the application of PSD to sources on 
CNMI and would fulfill EPA's more recent obligations to promulgate a 
FIP in the wake of our finding of failure by CNMI to submit SIPs for 
new or revised NAAQS in more recent years, including the 1997 eight-
hour ozone standard, the 1997 PM2.5 standard, and the 2006 
PM2.5 standard, to the extent that the required SIP 
submittals relate to PSD.

II. Major Source Baseline Date

A. Background

    Section 325(a)(1) of the CAA authorizes EPA, upon petition by the 
Governor of Guam, American Samoa, the Virgin Islands, or CNMI, to 
exempt any person or source or class of persons in such territory from 
any requirement of the Act other than section 112 (``Hazardous air 
pollutants'') or any requirement under section 110 (``[SIPs] for 
[NAAQS]'') or part D (``[SIP] Requirements for Nonattainment Areas'') 
necessary to attain or maintain a NAAQS. An exemption may be granted if 
EPA finds that compliance with such requirement is not feasible or is 
unreasonable due to unique geographical, meteorological, or economic 
factors of such territory, or such other local factors as EPA deems 
significant.

B. CNMI's Petition for Change of Major Source Baseline Date

    On October 6, 1998, the Honorable Pedro P. Tenorio, Governor of 
CNMI, petitioned EPA to establish the effective date of EPA's final 
conditional exemption from title V requirements as the major source 
baseline date.\3\ See letter from Pedro P. Tenorio, Governor, to 
Felicia Marcus, Region IX Regional Administrator, October 6, 1998. 
EPA's final conditional exemption was published on November 13, 1996 
and became effective on January 13, 1997.\4\
---------------------------------------------------------------------------

    \3\ The Governor of CNMI also requested that EPA allow merging 
of the power plant stacks at a source, as a dispersion technique, in 
order for power plants operated by the Commonwealth Utilities 
Corporation (CUC) to meet the NAAQS and PSD increments. EPA is not 
taking action on this additional request in this action.
    \4\ The Governor's October 6, 1998 request states: ``In 1994, 
[CNMI] petitioned the [EPA], under Section 325(a) of the [CAA] for 
an exemption from Title V which pertains to establishment of an 
operating permit program. A conditional waiver was granted on 
November 13, 1996, . . . . Insofar as the CNMI was not covered by 
the CAA in 1975, we believe that the appropriate baseline PSD date 
for major sources should be the effective date of the Title V 
waiver, January 13, 1996. Accordingly, we request an amendment to 
our original 1996 Title V waiver clarifying that the major source 
PSD baseline date is the effective date of the waiver.'' We 
interpret the Governor's reference to ``January 13, 1996'' to be 
mistaken and that ``January 13, 1997'' was the intended date, since 
the latter represents the effective date of EPA's final conditional 
exemption published on November 13, 1996. See 61 FR 58284 (November 
13, 1996).
---------------------------------------------------------------------------

    Under the PSD program, the ``major source baseline date'' is the 
date after which actual emissions changes associated with modifications 
(i.e., physical changes or changes in the method of operation) at a 
major stationary source affect the available PSD increment. Other 
changes in actual emissions occurring at any source after the major 
source baseline date do not affect the increment, but instead (until 
after the minor source baseline date is established) contribute to the 
baseline concentration. The ``trigger date'' is the date after which 
the minor source baseline date may be established.
    Both the major source baseline date and the trigger date are fixed 
dates, although the specific dates vary among the pollutants for which 
PSD increments have been established: Sulfur dioxide and respirable 
particulate matter (PM10), fine particulate matter 
(PM2.5) and nitrogen dioxide. Under 40 CFR 52.21(b)(14), the 
major source baseline date for sulfur dioxide and PM10 is 
January 6, 1975, and the trigger date for those pollutants is August 7, 
1977. For nitrogen dioxide, both the major source baseline date and the 
trigger date are February 8, 1988. For PM2.5, the major 
source baseline date is October 20, 2010, and the trigger date for 
those pollutants is October 20, 2011. The ``minor source baseline 
date'' is the earliest date after the trigger date on which a complete 
PSD application is received by the permit reviewing agency, and thus is 
not a fixed date.
    In concept, the ``major source baseline date'' establishes a marker 
in time to track consumption (or expansion) of PSD increments due to 
modifications at major sources that occur prior to the ``minor source 
baseline date,'' after which all types of emissions increases and 
decreases (including mobile sources), i.e., not just those related to 
modifications at major stationary sources, consume (or expand) the 
available increment. Moreover, the trigger date is the marker in time 
after which the ``minor source baseline date'' can be established, and 
thus, there is no purpose in establishing a ``major source baseline 
date'' after a ``trigger date.''
    The Governor's request refers only to the ``major source baseline 
date'' and does not refer to the ``trigger date,'' but because, as 
explained above, granting a change to the ``major source baseline 
date'' without a corresponding change to the ``trigger date'' would be 
pointless given the connection between the two terms, we interpret the 
Governor's request as applying to both terms. Also, the Governor's 
request was not pollutant-specific, but we interpret it to refer to all 
pollutants for which the major source baseline date and trigger date 
were established under EPA's PSD regulations at the time of the 
Governor's 1998 petition (i.e., sulfur dioxide, PM10, and 
nitrogen dioxide, but not PM2.5).\5\
---------------------------------------------------------------------------

    \5\ CNMI's 1998 request did not apply to the PM2.5 
NAAQS because the increments, major source baseline date, and 
trigger date for PM2.5 were not established until 2010. 
See 75 FR 64864 (October 20, 2010). If this proposed action is 
finalized as proposed, the major source baseline date and trigger 
date for PM2.5 in CNMI would be October 20, 2010 and 
October 20, 2011, respectively, as set forth at 40 CFR 
52.21(b)(14)(i)(c) and 40 CFR 52.21(b)(14)(ii)(c).

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

C. EPA's Evaluation of CNMI's Petition and Proposed Action

    CNMI has petitioned EPA to exempt CNMI from the original PSD major 
source baseline date and to establish January 13, 1997 as the PSD major 
source baseline date for CNMI. As explained above, changing the major 
source baseline date would also require changing the trigger date. 
Changing the major source PSD baseline date (and trigger date) will 
allow existing and future sources on CNMI to use more increment than 
would have been the case if the original major source baseline date 
applied, but sources will still be required to comply with NAAQS 
limits, and with the increment limits calculated from the new 1997 PSD 
major source baseline date.
    Leaving the major source PSD baseline date unchanged would create a 
unique burden on sources in CNMI. Other States and territories were 
clearly included in the scope of the original PSD regulations and thus 
have been aware since the late 1970's of the need to quantify major 
source baseline emissions as of the original major source baseline date 
and to track emissions changes due to modifications at such major 
sources in order to calculate available increment when the minor source 
baseline date is established by the first complete PSD application in a 
given area. Because the Federal PSD regulations were not previously 
incorporated into the applicable plan for CNMI, neither CNMI nor 
sources on CNMI determined the respective baseline of source emissions 
on the original PSD major source baseline date, or changes to that 
baseline over time. It would create a unique burden if CNMI must 
attempt to reconstruct a complete baseline inventory working from the 
original major source baseline dates, including sources which may have 
existed in the 1970's but no longer exist today. Applying PSD 
regulations to CNMI with the original major source baseline dates would 
thus create a significant burden on new sources and regulators 
attempting to analyze PSD increment changes. This constitutes a ``local 
factor'' that is ``significant'' in EPA's judgment for the purposes of 
CAA section 325(a) because of the complications it creates for 
implementation of the PSD program in CNMI.
    Moreover, the specific date of January 13, 1997 as an alternate 
major source baseline date is appropriate given that it represents the 
effective date of EPA's approval of CNMI's request for a conditional 
exemption from the requirement to develop, submit for approval, and 
implement a title V operating permit program, given that one of the 
applicable conditions for granting the exemption was a continuing 
obligation on CNMI to implement its NSR program in such a way as to 
protect the NAAQS and the PSD increments. See 40 CFR 69.32(c)(1). Prior 
to this date, EPA had not provided clear instructions to CNMI with 
respect to the applicability of the PSD program, and correspondingly 
the need to quantify major source baseline emissions as of the original 
major source baseline date and to track emissions changes due to 
modifications at such major sources in order to calculate available 
increment.
    Lastly, we note that approval of the alternate major source 
baseline date and trigger date for CNMI would not be expected to have 
any effect on the PSD programs of any other state or territory given 
prevailing easterly winds and the location of the nearest state or 
territory, i.e., Guam, which is approximately 110 miles south of CNMI.
    Therefore, pursuant to section 325(a)(1) of the CAA, EPA is 
proposing to grant the CNMI Governor's 1998 request to establish the 
effective date of EPA's final conditional exemption from title V 
requirements as the major source baseline date. Specifically, in 
granting this request, EPA is proposing to establish January 13, 1997 
as the PSD major source baseline date and trigger date (with respect to 
sulfur dioxide, PM10, and nitrogen dioxide) for sources in 
CNMI.\6\
---------------------------------------------------------------------------

    \6\ As noted in footnote 5 of this document, neither the request 
nor our approval relates to the PM2.5 NAAQS. If this 
action is finalized as proposed, the PM2.5 major source 
baseline date and trigger date would be the dates as provided in 40 
CFR 52.21(b)(14)(i)(c) and (ii)(c). Moreover, any baseline dates or 
trigger dates that EPA establishes for new or modified NAAQS in 
future revisions to the Federal PSD regulations would be established 
in those revisions and would not be subject to the January 13, 1997 
baseline date and trigger date proposed for approval herein.
---------------------------------------------------------------------------

III. Corrections

A. Background

    Section 110(k)(6) of the CAA provides: ``Whenever [EPA] determines 
that [EPA's] action approving, disapproving, or promulgating any plan 
or plan revision (or part thereof), area designation, redesignation, 
classification, or reclassification was in error, [EPA] may in the same 
manner as the approval, disapproval, or promulgation revise such action 
as appropriate without requiring any further submission from the State. 
Such determination and the basis thereof shall be provided to the State 
and public.'' We interpret this provision to authorize the Agency to 
make corrections to a promulgated regulation when it is shown to our 
satisfaction that (1) we clearly erred in failing to consider or 
inappropriately considering information made available to EPA at the 
time of the promulgation, or the information made available at the time 
of promulgation is subsequently demonstrated to have been clearly 
inadequate, and (2) other information persuasively supports a change in 
the regulation. See 57 FR 56762, at 56763 (November 30, 1992).

B. Proposed Action

    First, under section 110(k)(6), EPA is proposing to amend 40 CFR 
52.02 and 52.16 to include references to CNMI or subpart FFF (which 
lists the applicable CNMI plan). EPA should have added these references 
in 1986 when the Agency took its first action on the CNMI SIP and 
thereby added subpart FFF to part 52, but failed to do so. See 51 
40798, at 40799 (November 10, 1986). We propose to add the appropriate 
references through this action.
    Second, under section 110(k)(6), EPA is proposing to correct the 
inadvertent listing of the ``Part VIII'' rules in table 52.2920 in 40 
CFR 52.2920 (``Identification of plan''), which sets forth EPA-approved 
regulations in the CNMI SIP. Part VIII of CNMI's air pollution control 
regulations consists of general prohibitory rules (that establish 
controls on open and agricultural burning, visible emissions, fugitive 
dust, incineration, process industries, and sulfur oxides from fuel 
combustion) and variance provisions. EPA has not taken action on any of 
the Part VIII rules and, thus, Part VIII should not have been listed in 
table 52.2920 in 40 CFR 52.2920. The Part VIII rules were inadvertently 
listed when EPA revised the format for the CNMI SIP. See 70 FR 44478, 
at 44481 (August 3, 2005). EPA proposes to correct this error in this 
action.
    Third, pursuant to section 110(k)(6), EPA is proposing to remove 
the words (``of lead'') in 40 CFR 52.2921(c)(1)(i), which presents the 
original ``Identification of plan'' prior to EPA's revision of the 
format for the CNMI SIP in 2005. In 1987, in the original 
``Identification of plan'' section, EPA mistakenly included the phrase 
``of lead'' in the description of the rules that we approved in 
November 1987. 52 FR at 43574, at 43575 (November 13, 1987). Both CNMI 
and EPA have understood the 1987 approval to cover the general NSR 
regulations as they apply to all criteria air pollutants regulated 
therein,

[[Page 70253]]

and not just to lead, which was the subject of a previous action. See 
51 FR 40798 (November 10, 1986). This revision would correct the 
wording in 40 CFR 52.2921(c)(1)(i) to match the intent of CNMI and EPA 
that the approval was of the generic NSR regulations. In addition, the 
presence of the reference to ``of lead'' in connection with EPA's 1987 
SIP approval is potentially confusing, and thus, harmful to the 
regulated community, CNMI, and EPA.

IV. Proposed Action and Request for Public Comment

    Under section 110(k) of the CAA, EPA is proposing to disapprove the 
CNMI SIP with respect to PSD, and incorporate by reference the Federal 
PSD regulations into the applicable CNMI plan.\7\ EPA is also proposing 
to approve a petition by CNMI for an exemption of the PSD major source 
baseline dates and trigger dates for sulfur dioxide, PM10, 
and nitrogen dioxide under Federal PSD regulations, and to establish an 
alternate date, January 13, 1997, as the major source baseline date and 
trigger date for those pollutants in CNMI. Lastly, in addition to 
proposing conforming amendments to 40 CFR part 52, subparts A and FFF 
and to 40 CFR part 69, subpart C, EPA is also proposing to make certain 
corrections to 40 CFR part 52 that were made in previous rulemakings.
---------------------------------------------------------------------------

    \7\ While EPA is proposing to disapprove the CNMI with respect 
to PSD, such disapproval would not affect the validity of any 
previously approved rules in the CNMI SIP. If finalized as proposed, 
such SIP rules would continue to be part of the applicable CNMI plan 
unless and until EPA approves their revocation or revision.
---------------------------------------------------------------------------

    If finalized as proposed, this action would establish EPA's PSD 
regulations as a basic element of the applicable implementation plan 
for CNMI and, through the exemption, would establish a major source 
baseline date and trigger date for sulfur dioxide, PM10, and 
nitrogen dioxide on CNMI of January 13, 1997.
    EPA is soliciting public comments on the issues discussed in this 
document or on other relevant matters. We will accept comments from the 
public on this proposal for the next 30 days. Request for a public 
hearing must be received within the next 15 days. If we receive a 
request for a public hearing, we will publish information related to 
the timing and location of the hearing and the timing of a new deadline 
for public comment.

V. Statutory and Executive Order Reviews

A. Executive Order 12866, Regulatory Planning and Review

    This proposed action is not a ``significant regulatory action'' 
under the terms of Executive Order (EO) 12866 (58 FR 51735, October 4, 
1993) and is therefore not subject to review by the Office of 
Management and Budget (OMB).

B. Paperwork Reduction Act

    This proposed action does not impose an 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).

C. Regulatory Reduction Act

    The Regulatory Flexibility Act (RFA) generally requires an agency 
to conduct a regulatory flexibility analysis of any rule subject to 
notice and comment rulemaking requirements unless the agency certifies 
that the rule will not have a significant economic impact on a 
substantial number of small entities. Small entities include small 
businesses, small not-for-profit enterprises, and small governmental 
jurisdictions.
    This proposed rule will not have a significant impact on a 
substantial number of small entities because, while the disapproval of 
the CNMI SIP with respect to PSD would lead to the application of the 
Federal PSD regulations to CNMI, the basic PSD statutory requirements 
for major emitting facilities to obtain a PSD permit already apply 
within CNMI, and the incremental impact associated with application of 
the specific requirements under the Federal PSD regulations would be 
offset by EPA's grant of CNMI's petition for a waiver of the original 
PSD major source baseline dates. Therefore, I certify that this 
proposed action will not have a significant economic impact on a 
substantial number of small entities. Moreover, due to the nature of 
the Federal-State relationship under the Clean Air Act, preparation of 
flexibility analysis would constitute Federal inquiry into the economic 
reasonableness of State action. The Clean Air Act forbids EPA to base 
its actions concerning SIPs on such grounds. Union Electric Co., v. 
U.S. EPA, 427 U.S. 246, 255-66 (1976); 42 U.S.C. 7410(a)(2).

D. Unfunded Mandates Reform Act

    Under section 202 of the Unfunded Mandates Reform Act of 1995 
(``Unfunded Mandates Act''), signed into law on March 22, 1995, EPA 
must prepare a budgetary impact statement to accompany any proposed or 
final rule that includes a Federal mandate that may result in estimated 
costs to State, local, or tribal governments in the aggregate; or to 
the private sector, of $100 million or more. Under section 205, EPA 
must select the most cost-effective and least burdensome alternative 
that achieves the objectives of the rule and is consistent with 
statutory requirements. Section 203 requires EPA to establish a plan 
for informing and advising any small governments that may be 
significantly or uniquely impacted by the rule.
    EPA has determined that the proposed disapproval of the CNMI SIP 
with respect to PSD, considered together with the proposed 
incorporation of the Federal PSD regulations, and grant of an exemption 
request with respect to the PSD major source baseline date, does not 
include a Federal mandate that may result in estimated costs of $100 
million or more to either State, local, or tribal governments in the 
aggregate, or to the private sector. While the disapproval of the CNMI 
SIP with respect to PSD would lead to the application of the Federal 
PSD regulations to CNMI, the basic PSD statutory requirements for major 
emitting facilities to obtain a PSD permit already apply within CNMI, 
and the incremental impact associated with application of the specific 
requirements under the Federal PSD regulations would be offset by EPA's 
grant of CNMI's petition for a waiver of the original PSD major source 
baseline dates. Accordingly, the additional costs to State, local, or 
tribal governments, or to the private sector, would not be significant 
for the purposes of section 202 of the Unfunded Mandates Act.

E. Executive Order 13132, Federalism

    Federalism (64 FR 43255, August 10, 1999) revokes and replaces 
Executive Orders 12612 (Federalism) and 12875 (Enhancing the 
Intergovernmental Partnership). Executive Order 13132 requires EPA to 
develop an accountable process to ensure ``meaningful and timely input 
by State and local officials in the development of regulatory policies 
that have federalism implications.'' ``Policies that have federalism 
implications'' is defined in the Executive Order to include regulations 
that 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.'' Under Executive Order 13132, EPA may not issue a 
regulation that has federalism implications, that imposes substantial

[[Page 70254]]

direct compliance costs, and that is not required by statute, unless 
the Federal government provides the funds necessary to pay the direct 
compliance costs incurred by State and local governments, or EPA 
consults with State and local officials early in the process of 
developing the proposed regulation. EPA also may not issue a regulation 
that has federalism implications and that preempts State law unless the 
Agency consults with State and local officials early in the process of 
developing the proposed regulation.
    This proposed rule 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 Executive Order 13132, 
because it merely proposes to disapprove the CNMI SIP with respect to 
PSD, to incorporate the Federal PSD regulations, and to grant an 
exemption request with respect to the PSD major source baseline date, 
and does not alter the relationship or the distribution of power and 
responsibilities established in the Clean Air Act. Thus, the 
requirements of section 6 of the Executive Order do not apply to this 
rule.

F. Executive Order 13175, Coordination With Indian Tribal Governments

    Executive Order 13175, entitled ``Consultation and Coordination 
with Indian Tribal Governments'' (65 FR 67249, November 9, 2000), 
requires EPA to develop an accountable process to ensure ``meaningful 
and timely input by tribal officials in the development of regulatory 
policies that have tribal implications.'' This proposed rule does not 
have tribal implications, as specified in Executive Order 13175. It 
will not have substantial direct effects on tribal governments, 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. Thus, Executive Order 13175 does not 
apply to this rule.

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

    EPA interprets Executive Order 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 Executive Order has the potential to influence the regulation. This 
rule is not subject to Executive Order 13045, because it proposes to 
disapprove the CNMI SIP with respect to PSD, to incorporate the Federal 
PSD regulations, and to grant an exemption request with respect to the 
PSD major source baseline date.

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

    This proposed rule is not subject to Executive Order 13211, 
``Actions Concerning Regulations That Significantly Affect Energy 
Supply, Distribution, or Use'' (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 of the National Technology Transfer and Advancement Act 
(NTTAA) of 1995 requires Federal agencies to evaluate existing 
technical standards when developing a new regulation. To comply with 
NTTAA, EPA must consider and use ``voluntary consensus standards'' 
(VCS) if available and applicable when developing programs and policies 
unless doing so would be inconsistent with applicable law or otherwise 
impractical.
    EPA believes that VCS are inapplicable to this proposed action. 
Today's action does not require the public to perform activities 
conducive to the use of VCS.

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

    Executive Order (EO) 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.
    This proposed rulemaking includes a review of the CNMI SIP relative 
to PSD requirements, incorporation of EPA's PSD regulation into the 
applicable CNMI plan, and a grant of an exemption to CNMI to the 
original PSD major source baseline dates. With respect to EPA's review 
of the CNMI SIP, EPA's role is to approve or disapprove state choices, 
based on the criteria of the Clean Air Act, and incorporation of EPA's 
PSD regulation is the established remedy for disapproval of the CNMI 
SIP with respect to PSD. Thus, the EPA lacks the discretionary 
authority to address environmental justice in those two aspects of this 
proposed rulemaking.
    EPA does have discretionary authority to address environment 
justice with respect to EPA's consideration of the exemption request 
from CNMI and has determined that this proposed action will not have 
disproportionately high and adverse human health or environmental 
effects on minority or low-income populations. This is because, due to 
the lack of documentation of major source emissions changes from the 
original PSD baseline dates, application of the original major source 
baseline dates could lead to speculative and uncertain estimates of PSD 
increment consumption and correspondingly speculative and uncertain 
levels of environmental protection. In contrast, EPA's grant of CNMI's 
exemption request sets the stage for consistent and uniform PSD 
increment tracking and protection within CNMI.
