Approval and Promulgation of Air Quality Implementation Plans; 
Massachusetts; State Implementation Plan Revision To Implement the 
Clean Air Interstate Rule

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: EPA is approving a State Implementation Plan (SIP) revision 
submitted by the State of Massachusetts on March 30, 2007. This 
revision addresses the requirements of EPA's Clean Air Interstate Rule 
(CAIR), promulgated on May 12, 2005 and subsequently revised on April 
28, 2006 and December 13, 2006. EPA has determined that the SIP 
revision fully implements the CAIR requirements for Massachusetts. 
Therefore, as a consequence of the SIP approval, the Administrator of 
EPA will also, in a separate document, issue a final rule to withdraw 
the Federal Implementation Plan (FIP) concerning NOX ozone-
season emissions for Massachusetts.
    In the SIP revision that EPA is approving, Massachusetts will meet 
CAIR requirements by participating in the EPA-administered cap-and-
trade program addressing NOX ozone-season emissions. 
Massachusetts's SIP revision is based on EPA's model CAIR 
NOX ozone season rule and is, in most respects, 
substantively identical to that model rule. The Massachusetts CAIR 
program has two major substantive differences from that model rule 
(expanded applicability, and a different methodology for allocating 
NOX allowances), both of which are consistent with the 
flexibility allowed under CAIR for state participation in the EPA-
administered cap-and-trade program. The SIP revision complies with the 
statutory and regulatory requirements for approval of a CAIR 
NOX ozone-season program. This action is being taken in 
accordance with the Clean Air Act.

EFFECTIVE DATE: This rule is effective on December 3, 2007.

I. What Action Is EPA Taking?

    EPA is approving a revision to Massachusetts's SIP, submitted on 
March 30, 2007. This SIP revision includes a new regulation, 310 CMR 
7.32, ``Massachusetts Clean Air Interstate Rule,'' and amendments to 
existing regulation 310 CMR 7.28, ``NOX Allowance Trading 
Program.'' In its SIP revision, Massachusetts will meet CAIR 
requirements by requiring certain electric generating units (EGUs) to 
participate in the EPA-administered State CAIR cap-and-trade program 
addressing NOX ozone-season emissions. EPA has determined 
that the Massachusetts SIP as revised meets the applicable requirements 
of CAIR. On August 1, 2007, EPA proposed approval of the Massachusetts 
SIP (see 72 FR 41970). No public comments were received on EPA's notice 
of proposed rulemaking (NPR).
    As a consequence of the SIP approval, the Administrator of EPA will 
also, in a separate document, issue a final rule to withdraw the FIP 
concerning NOX ozone-season emissions for Massachusetts. 
That action will delete and reserve 40 CFR 52.1140. The withdrawal of 
the CAIR FIP for Massachusetts is a conforming amendment that must be 
made once the

[[Page 67855]]

SIP is approved because EPA's authority to issue the FIP was premised 
on a deficiency in the SIP for Massachusetts. Once the SIP is fully 
approved, EPA no longer has authority for the FIP. Thus, EPA will not 
have the option of maintaining the FIP following the full SIP approval. 
Accordingly, EPA does not intend to offer an opportunity for a public 
hearing or an additional opportunity for written public comment on the 
withdrawal of the FIP.

II. What Is the Regulatory History and General Requirements of CAIR and 
the CAIR FIPs?

    The Clean Air Interstate Rule (CAIR) was published by EPA on May 
12, 2005 (70 FR 25162). In this rule, EPA determined that 28 States and 
the District of Columbia contribute significantly to nonattainment and 
interfere with maintenance of the national ambient air quality 
standards (NAAQS) for fine particles (PM2.5) and/or 8-hour 
ozone in downwind States in the eastern part of the country. As a 
result, EPA required those upwind States to revise their SIPs to 
include control measures that reduce emissions of SO2, which 
is a precursor to PM2.5 formation, and/or NOX, 
which is a precursor to both ozone and PM2.5 formation. For 
jurisdictions that contribute significantly to downwind 
PM2.5 nonattainment, CAIR sets annual State-wide emission 
reduction requirements (i.e., budgets) for SO2 and annual 
State-wide emission reduction requirements for NOX. 
Similarly, for jurisdictions that contribute significantly to 8-hour 
ozone nonattainment, CAIR sets State-wide emission reduction 
requirements for NOX for the ozone season (May 1st to 
September 30th). Under CAIR, States may implement these reduction 
requirements by participating in the EPA-administered cap-and-trade 
programs or by adopting other control measures. The first phase of 
NOX reductions starts in 2009 and continues through 2014, 
while the first phase of SO2 reductions starts in 2010 and 
continues through 2014. The second phase of reductions for both 
NOX and SO2 starts in 2015 and continues 
thereafter.
    More information on the regulatory history and requirements of CAIR 
and the CAIR FIPs is available in the NPR for this SIP Revision and 
will not be restated here.

III. EPA Analysis of Massachusetts's CAIR SIP Submittal

    A brief summary of EPA's review of Massachusetts's CAIR program is 
given below. Additional details regarding requirements of 
Massachusetts's 310 CMR 7.32 regulation and EPA's evaluation of this 
regulation are detailed in a memorandum dated July 16, 2007, entitled 
``Technical Support Document (TSD) for revisions to the Massachusetts 
SIP: 310 CMR 7.32 (`Massachusetts Clean Air Interstate Rule')'' and in 
the NPR for this SIP revision. The TSD and Massachusetts's CAIR SIP 
submittal are available in the docket supporting this action.

A. State Budgets for Allowance Allocations

    The CAIR NOX annual and ozone season budgets were 
developed from historical heat input data for EGUs. Using these data, 
EPA calculated annual and ozone season regional heat input values, 
which were multiplied by 0.15 pounds per million British thermal units 
(lb/mmBtu), for phase 1 of the CAIR program (2009-2014) and by 0.125 
lb/mmBtu, for phase 2 of the CAIR program (2015 and thereafter) to 
obtain regional NOX budgets for 2009-2014 and for 2015 and 
thereafter, respectively. EPA derived the State NOX annual 
and ozone season budgets from the regional budgets using State heat 
input data adjusted by fuel factors. Massachusetts, however, is only 
required to participate in the CAIR NOX ozone-season 
program, not the CAIR NOX annual or SO2 trading 
programs. Therefore, only CAIR NOX ozone-season budgets 
apply to the Massachusetts CAIR program.
    In today's action, EPA is approving Massachusetts's SIP revision of 
310 CMR 7.32. This SIP revision adopts the budgets established for the 
State in CAIR, i.e., 7,551 tons of NOX ozone-season 
emissions for CAIR phase 1 and 6,293 tons for CAIR phase 2, plus an 
additional 363 tons of NOX ozone-season emissions for both 
phases 1 and 2 to account for NOX emissions from ``non-EGU'' 
units from the Massachusetts NOX SIP Call trading program 
(see section III C below). The total NOX ozone-season budget 
is therefore 7,914 tons of NOX ozone-season emissions for 
CAIR phase 1 and 6,656 tons for CAIR phase 2. Massachusetts's SIP 
revision sets this budget as the total number of allowances (with each 
allowance authorizing one ton of NOX ozone-season emissions) 
available for allocation for each year under the EPA-administered CAIR 
cap-and-trade program.

B. CAIR Cap-and-Trade Programs

    The CAIR NOX annual and ozone-season model trading rules 
both largely mirror the structure of the NOX SIP Call model 
trading rule in 40 CFR part 96, subparts A through I. While the 
provisions of the NOX annual and ozone-season model rules 
are similar, there are some differences. For example, the 
NOX ozone season model rule reflects the fact that the CAIR 
NOX ozone season trading program replaces the NOX 
SIP Call trading program after the 2008 ozone season and is coordinated 
with the NOX SIP Call program. The NOX ozone 
season model rule provides incentives for early emissions reductions by 
allowing banked, pre-2009 NOX SIP Call allowances to be used 
for compliance in the CAIR NOX ozone-season trading program. 
In addition, States have the option of continuing to meet their 
NOX SIP Call requirement by participating in the CAIR 
NOX ozone season trading program and including all their 
NOX SIP Call trading sources in that program.
    In the SIP revision, Massachusetts will implement its CAIR budgets 
by requiring EGUs (as well as ``non-EGUs'' from its NOX SIP 
Call trading program, as discussed below) to participate in EPA-
administered cap-and-trade programs for NOX ozone-season 
emissions. Massachusetts has adopted a full SIP revision that adopts, 
with certain allowed changes discussed below, the CAIR model cap-and-
trade rules for NOX ozone-season emissions.

C. Applicability Provisions for Non-EGU NOX SIP Call Sources

    In general, the CAIR model trading rules apply to any stationary, 
fossil-fuel-fired boiler or stationary, fossil-fuel-fired combustion 
turbine serving at any time, since the later of November 15, 1990 or 
the start-up of the unit's combustion chamber, a generator with 
nameplate capacity of more than 25 MWe producing electricity for sale.
    States have the option of bringing in, for the CAIR NOX 
ozone-season program only, those units in the State's NOX 
SIP Call trading program that are not EGUs as defined under CAIR 
(herein called ``non-EGUs''). Under this option, the CAIR 
NOX ozone-season program must cover all large industrial 
boilers and combustion turbines, as well as any small EGUs (i.e. units 
serving a generator with a nameplate capacity of 25 MWe or less) that 
the State currently requires to be in the NOX SIP Call 
trading program.
    Massachusetts has chosen to expand the applicability provisions of 
the CAIR NOX ozone season trading program to include all 
units in the State's NOX SIP Call trading program. Units in 
the Massachusetts NOX SIP Call trading program include units 
that burn more than 50-percent fossil fuel and that have

[[Page 67856]]

a maximum heat-input capacity of 250 million British thermal units 
(MMBtu) or more, or serve a generator with a nameplate capacity of 15 
MWe or more. These units are included in the Massachusetts 
NOX SIP Call trading program whether or not they produce 
electricity for sale, and will be included in the Massachusetts CAIR 
program beginning with the control period in 2009. EPA has determined 
that Massachusetts 310 CMR 7.32 includes the allowable CAIR 
applicability provisions relating to adding all NOX SIP Call 
trading program units to the Massachusetts CAIR NOX ozone 
season program.

D. NOX Allowance Allocations

    Under the NOX allowance-allocation methodology in the 
CAIR model trading rules and in the CAIR FIP, NOX annual and 
ozone-season allowances are allocated to units that have operated for 
five years (i.e., ``existing units''), based on heat input data from a 
three-year period that are adjusted for fuel type by using fuel factors 
of 1.0 for coal, 0.6 for oil, and 0.4 for other fuels. The CAIR model 
trading rules and the CAIR FIP also provide a new unit set-aside from 
which units without five years of operation are allocated allowances 
based on the units' prior year emissions.
    States may establish in their SIP submissions a different 
NOX allowance-allocation methodology that will be used to 
allocate allowances to sources in the States if certain requirements 
are met concerning the timing of submission of units' allocations to 
the Administrator for recordation and the total amount of allowances 
allocated for each control period. In adopting alternative 
NOX allowance-allocation methodologies, States have 
flexibility with regard to:
    1. The cost to recipients of the allowances, which may be 
distributed for free or auctioned;
    2. The frequency of allocations;
    3. The basis for allocating allowances, which may be distributed, 
for example, based on historical heat input or electric and thermal 
output; and
    4. The use of allowance set-asides and, if used, their size.
    Massachusetts has chosen to replace the provisions of the CAIR 
NOX ozone-season model trading rule concerning allowance 
allocations with its own methodology. Massachusetts's CAIR program 
codified at 310 CMR 7.32 distributes NOX ozone-season 
allowances based upon historical electric and thermal output, rather 
than heat input. Massachusetts also provides a percentage of allowances 
for Public Benefit and new unit set-asides.
    Massachusetts's CAIR program includes both a Public Benefit set-
aside (PBSA) to encourage Energy Efficiency Projects (EEPs) and 
Renewable Energy Projects (REPs), and a new unit set-aside to allow for 
addition of new units. Both of these types of set-asides were included 
in the State's NOX SIP Call trading program.
    Massachusetts has set a new unit set-aside at 5 percent of the 
State's CAIR budget for both phases of the CAIR program. Therefore, the 
new unit set-aside includes 396 CAIR NOX ozone-season 
allowances during CAIR phase 1 (2009-2014), and 333 allowances during 
CAIR phase 2 (2015 and thereafter). Massachusetts has set a PBSA at 10 
percent of the State's CAIR budget for both phases of the CAIR program. 
Therefore, the PBSA includes 791 CAIR NOX ozone-season 
allowances during CAIR phase 1 (2009-2014), and 666 allowances during 
CAIR phase 2 (2015 and thereafter). Information on the Banking and 
Transferring of Set-Asides in the Massachusetts CAIR program is 
available in the NPR and will not be restated here.
    Massachusetts has chosen to replace the provisions of the CAIR 
NOX ozone-season model trading rule concerning allowance 
allocations with a methodology similar to that used in the 
Massachusetts NOX SIP Call trading program. This 
methodology, which is based on energy output, allocates allowances to 
existing units and, to the extent possible, to new units based on their 
steam and/or electricity output. More details on Massachusetts's 
methodology for allocating CAIR allowances, as well as information on 
Massachusetts CAIR permits and requirements for facilities to report 
emissions data, can be found in the TSD and the NPR and will not be 
restated here.

E. Individual Opt-in Units

    The Massachusetts CAIR SIP does not include opt-in provisions 
because the State has chosen to allocate CAIR allowances using an 
energy-output methodology that cannot be used for opt-in sources under 
the model CAIR NOX ozone-season trading rule. The 
Massachusetts NOX SIP Call trading program (310 CMR 7.28), 
however, does allow for opt-in sources (although no sources have opted 
into this program to date). Therefore, sources that wish to be part of 
the Massachusetts CAIR program can take advantage of the opt-in 
provisions of the State's NOX SIP Call program until the end 
of 2008. Beginning with the 2009 ozone season, the NOX SIP 
Call program will be replaced by the State's CAIR Program, and no 
further opt-in units will be allowed.

IV. Final Action

    EPA is approving state regulations 310 CMR 7.32 (``Massachusetts 
CAIR'') and amendments to 310 CMR 7.28 (``NOX Allocation 
Trading Program'') as a revision to the Massachusetts SIP. Under this 
SIP revision, Massachusetts will participate in the EPA-administered 
cap-and-trade program for NOX ozone-season emissions. The 
SIP revision meets the applicable requirements in 40 CFR 51.123(o) and 
(aa), with regard to NOX ozone season emissions. EPA has 
determined that the SIP as revised meets the requirements of CAIR. As a 
consequence of the SIP approval, the Administrator of EPA will also 
issue, without providing an opportunity for a public hearing or an 
additional opportunity for written public comment, a final rule to 
withdraw the CAIR FIP concerning NOX ozone-season emissions 
for Massachusetts. That action will delete and reserve 40 CFR 52.1140 
in Part 52.

V. When Is This Action Effective?

    EPA finds that there is good cause for this approval to become 
effective on the date of publication of this action in the Federal 
Register, because a delayed effective date is unnecessary due to the 
nature of the approval, which allows the State to make allocations 
under its CAIR rules. The expedited effective date for this action is 
authorized under both 5 U.S.C. 553(d)(1), which provides that rule 
actions may become effective less than 30 days after publication if the 
rule ''grants or recognizes an exemption or relieves a restriction'' 
and 5 U.S.C. 553(d)(3), which allows an effective date less than 30 
days after publication ''as otherwise provided by the agency for good 
cause found and published with the rule.'' CAIR SIP approvals exempt 
states and CAIR sources within states from being subject to allowance 
allocation provisions in the CAIR FIPs that otherwise would apply, 
allowing States to make their own allowance allocations based on their 
SIP-approved State rule. The exemption from these obligations is 
sufficient reason to allow an expedited effective date of this rule 
under 5 U.S.C. 553(d)(1). In addition, Massachusetts's exemption from 
these obligations provides good cause to make this rule effective on 
the date of publication of this action in the Federal Register, 
pursuant to 5 U.S.C. 553(d)(3). The purpose of the 30-day waiting 
period prescribed in 5 U.S.C. 553(d) is to give affected parties a 
reasonable time to adjust their behavior and prepare before the final 
rule takes effect. Where,

[[Page 67857]]

as here, the final rule grants an exemption rather than imposing 
obligations, and where the effect of the final rule is simply to 
approve for Federal purposes obligations that are already effective 
under state law, affected parties, such as the State of Massachusetts 
and CAIR sources within the State, do not need time to adjust and 
prepare before the rule takes effect.

VI. 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 (Public Law 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.
    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.).
    The Congressional Review Act, 5 U.S.C. section 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. 
section 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 February 1, 2008. 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 enforce its requirements. (See section 307(b)(2).)
