[EPA-R01-OAR-2007-0452; A-1-FRL-8491-6]
Approval and Promulgation of Air Quality Implementation Plans;
Connecticut; Interstate Transport of Pollution
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: EPA is proposing to approve a State Implementation Plan (SIP)
revision submitted by the Connecticut Department of Environmental
Protection (CTDEP). This SIP revision addresses the provisions of the
Clean Air Act that require each state to submit a SIP to address
emissions that may adversely affect another state's air quality through
interstate transport. CTDEP has adequately addressed the four distinct
elements related to the impact of interstate transport of air
pollutants. These include prohibiting significant contribution to
downwind nonattainment of the National Ambient Air Quality Standards
(NAAQS), interference with maintenance of the NAAQS, interference with
plans in another state to prevent significant deterioration of air
quality, and interference with efforts of other states to protect
visibility. The intended effect of this action is to propose approval
of this revision to the Connecticut SIP. This action is being taken
under the Clean Air Act.

I. Rulemaking Information

III. Statutory and Executive Order Reviews
I. Rulemaking Information
EPA is proposing to approve a SIP revision submitted by the
Connecticut Department of Environmental Protection (CTDEP). This SIP
revision addresses the requirements of the Clean Air Act (CAA) section
110(a)(2)(D)(i). This CAA section requires each state to submit a SIP
that prohibits emissions that could adversely affect another state. The
SIP must prevent sources in the state from emitting pollutants in
amounts which will: (1) Contribute significantly to downwind
nonattainment of the NAAQS; (2) interfere with maintenance of the
NAAQS; (3) interfere with provisions to prevent significant
deterioration of air quality; and (4) interfere with efforts to protect
visibility. EPA issued guidance on August 15, 2006, relating to SIP
submissions to meet the requirements of section 110(a)(2)(D)(i).
\1\Connecticut
[[Page 62421]]
submitted their SIP revision on March 13, 2007.
---------------------------------------------------------------------------
\1\ ``Guidance for State Implementation Plan (SIP) Submissions
to Meet Current Outstanding Obligations Under Section
110(a)(2)(D)(i) for the 8-Hour Ozone and PM2.5 National
Ambient Air Quality Standards,'' Memorandum from William T. Harnett,
EPA OAQPS, to EPA Regional Air Division Directors, August 15, 2006.
---------------------------------------------------------------------------
On May 12, 2005, EPA promulgated the Clean Air Interstate Rule
(CAIR). (See 70 FR 25162.) CAIR requires States to reduce emissions of
sulfur dioxide (SO2) and nitrogen oxides (NOX)
that significantly contribute to, and interfere with maintenance of,
the national ambient air quality standards for fine particulates and/or
ozone in any downwind state. CAIR establishes State budgets for
SO2 and NOX and requires States to submit SIP
revisions that implement these budgets in States that EPA concluded did
contribute to nonattainment in downwind states.
Connecticut is a CAIR state for ozone only (70 FR 25162; May 12,
2005). Since Connecticut is in CAIR, EPA has already concluded that
Connecticut can meet its 110(a)(2)(D)(i) obligations to address the
significant contribution and interference with maintenance requirements
by complying with the CAIR requirements. Connecticut has proposed its
CAIR SIP and submitted it to EPA for parallel processing on April 26,
2007. EPA proposed approval of Connecticut's CAIR SIP on August 31,
2007 (72 FR 50305). Connecticut submitted its final adopted CAIR SIP on
September 12, 2007. Assuming EPA ultimately approves Connecticut's CAIR
SIP, EPA will have determined that Connecticut has addressed section
110(a)(2)(D)(i) for ozone.
For fine particles (PM2.5), the EPA CAIR modeling
determined that the Connecticut emissions do not meet or exceed the 0.2
[mu]g/m3 average annual threshold that EPA established to
determine significant PM2.5 impact on another state in the
projection year 2010. This shows that emissions from Connecticut do not
contribute significantly to downwind nonattainment of the annual
PM2.5 standard. In addition, air quality modeling conducted
by Connecticut also concluded that emissions of PM2.5 do not
significantly contribute to downwind PM2.5 nonattainment.\2\
Connecticut, however, does contain a nonattainment area for the annual
PM2.5 standard and is required to prepare a PM2.5
attainment demonstration. Connecticut is on track to meet the April
2008 submittal deadline for the attainment demonstration SIP for the
annual PM2.5 standard.\3\ EPA has no evidence that emissions
of other pollutants in Connecticut contribute to downwind
nonattainment. Therefore, EPA has determined that through the above
actions, Connecticut has adequately addressed the first two elements of
the CAA section 110(a)(2)(D)(i) requirements (i.e., to prevent
emissions that contribute significantly to downwind nonattainment of,
or interfere with maintenance of, the NAAQS).
---------------------------------------------------------------------------
\2\ Connecticut performed industrial source complex air quality
modeling for PM2.5. The details of this modeling can be
found in the Connecticut technical support document, ``CT DEP,
Bureau of Air Management--Recommendation for PM2.5
Designation Technical Support Document,'' available in the docket
for this action.
\3\ On December 17, 2006, EPA revised the 24-hour
PM2.5 standard. Nonattainment areas for the new standard
have not yet been determined.
---------------------------------------------------------------------------
The third element CTDEP addressed was prevention of significant
deterioration (PSD). For ozone and particulate matter, the state has
met the obligation by confirming that major sources in the state are
currently subject to PSD and/or New Source Review (NSR) programs that
implement the 8-hour ozone standard and the PM2.5 standard.
CTDEP is addressing the fourth element of visibility through its
participation in MANE-VU, which is the regional planning organization
for addressing visibility in the Northeastern and Mid-Atlantic States.
MANE-VU has undertaken extensive modeling in support of Regional Haze
SIP development. Although it is not possible at this time to make a
final assessment whether there is any interference with measures in the
applicable SIP for another State designed to ``protect visibility'' for
the 8-hour ozone and PM2.5 NAAQS until the Connecticut
regional haze SIP is developed and approved, preliminary results
indicate that Connecticut has a minimal contribution to the
``visibility impact'' on any Class 1 area.\4\ Connecticut will be in a
more advantageous position to address the visibility projection
requirements once the final regional haze SIP has been developed.
Regional haze SIPs are due December 17, 2007.

Atlantic States: MANE-VU Contribution Assessment,'' Northeast States
for Coordinated Air Use Management (NESCAUM), August 2006.
---------------------------------------------------------------------------
A public hearing on Connecticut's section 110(a)(2)(D)(i) SIP was
held by the state on January 30, 2007. No adverse comments were
received.
II. Proposed Action
EPA is proposing to approve the CAA section 110(a)(2)(D)(i) SIP
revision submitted by Connecticut on March 13, 2007. EPA has reviewed
Connecticut's 110(a)(2)(D)(i) SIP and has found that it is consistent
with EPA's guidance and the relevant CAA requirements as discussed
above. EPA is soliciting public comments on the issues discussed in
this document. These comments will be considered before taking final
action.
III. Statutory and Executive Order Reviews
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. For this
reason, this action is also not subject to Executive Order 13211,
``Actions Concerning Regulations That Significantly Affect Energy
Supply, Distribution, or Use'' (66 FR 28355, May 22, 2001). 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 (Pub. L. 104-4).
This rule also does not have tribal implications because it will
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). This action also does not have Federalism
implications because it does 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 (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
``Protection of Children from Environmental Health Risks and Safety
Risks'' (62 FR 19885, April 23, 1997), because it approves a state rule
implementing a Federal standard.
[[Page 62422]]
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. 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.)
