40 CFR Part 52

[EPA-R07-OAR-2006-1015; FRL-8285-1]


Approval and Promulgation of Implementation Plans; Iowa; 
Interstate Transport of Pollution

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rule.

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

SUMMARY: EPA is revising the Iowa State Implementation Plan (SIP) for 
the purpose of approving the Iowa Department of Natural Resources' 
(IDNR) actions to address the ``good neighbor'' provisions of the Clean 
Air Act section 110(a)(2)(D)(i). These provisions require each state to 
submit a SIP that prohibits emissions that adversely affect another 
state's air quality through interstate transport. IDNR 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, prevention of significant deterioration of air quality, and 
protection of visibility. The requirements for public notification were 
also met by IDNR.

DATES: This direct final rule will be effective May 7, 2007, without 
further notice, unless EPA receives adverse comment by April 9, 2007. 
If adverse comment is received, EPA will publish a timely withdrawal of 
the direct final rule in the Federal Register informing the public that 
the rule will not take effect.

SUPPLEMENTARY INFORMATION: Throughout this document whenever

[[Page 10381]]

``we,'' ``us,'' or ``our'' is used, we mean EPA. This section provides 
additional information by addressing the following questions:

What is being addressed in this document?
What action is EPA taking?

What is being addressed in this document?

    EPA is making a revision to the SIP for the purpose of approving 
the IDNR's actions to address 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 
nonattainment of the NAAQS, (2) interfere with maintenance of the NAAQS 
in another state, (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). As discussed 
below, Iowa's analysis of its SIP with respect to the statutory 
requirements is consistent with the guidance.
    The IDNR has addressed the first two of these elements by the 
adoption of the Clean Air Interstate Rule (CAIR) model rules that 
require Iowa sources to participate in the EPA-administered cap and 
trade program for nitrogen oxides (NO<INF>X</INF>) and sulfur dioxide. 
Participation in this program will prohibit emissions from the state 
that will contribute significantly to nonattainment or interfere with 
the maintenance of the NAAQS in any downwind state. As previously 
determined by EPA, submittal of a SIP revision to satisfy CAIR also 
fulfills the state's obligations that pertain to ``significant 
contribution'' and ``interference with maintenance'' (70 FR 25162). It 
should be noted that EPA will act on Iowa's CAIR SIP in a separate 
rulemaking, and this action makes no conclusion with respect to 
approvability of that submittal.
    The third element IDNR addressed was prevention of significant 
deterioration (PSD). For 8-hour ozone, the state has met the obligation 
by confirming that major sources in the state are currently subject to 
PSD programs that implement the 8-hour ozone standard and that the 
state is on track to meet the June 15, 2007, deadline for SIP 
submissions adopting any relevant requirements of the Phase II ozone 
implementation rule. For PM<INF>2.5</INF>, the state has confirmed that 
the state's PSD program is being implemented in accordance with EPA's 
interim guidance calling for the use of PM<INF>10</INF> as a surrogate 
for PM<INF>2.5</INF> for the purposes of PSD review. Controlling 
PM<INF>10</INF> emissions and analyzing impacts on the environment 
serves as a surrogate approach for reducing PM<INF>2.5</INF> emissions 
and minimizing impacts to air quality. Once PM<INF>2.5</INF> guidance 
is finalized by EPA, IDNR commits to transitioning from use of the 
interim PM<INF>2.5</INF> guidance to the final PM<INF>2.5</INF> 
implementation guidance after approval of the PM<INF>2.5</INF> SIP 
revision (The submittal is due in April 2008).
    It should be noted that Iowa is currently designated attainment/
unclassifiable for both the 8-hour ozone and PM<INF>2.5</INF> NAAQS.
    At this time, it is not possible for IDNR to accurately determine 
whether there is interference with measures in another state's SIP 
designed to protect visibility, which is the fourth element that was 
addressed. Technical projects relating to visibility degradation 
source-receptor relationships are under development. Iowa will be in a 
more advantageous position to address the visibility projection 
requirements once the initial regional haze SIP has been developed. 
IDNR intends to meet the December 17, 2007, submittal deadline for the 
regional haze SIP.
    A public hearing with regard to this action was held by the state. 
No comments were received.
    With this action, the non-regulatory text in 40 CFR 52.820(e) is 
revised to reflect that IDNR addressed the elements of the CAA section 
110(a)(2)(D)(i) submittal.

What action is EPA taking?

    EPA is approving this revision submitted by Iowa and is revising 40 
CFR 52.820 to reflect that the IDNR has adequately addressed the 
required elements of the CAA section 110(a)(2)(D)(i) SIP. Please note 
that if EPA receives adverse comments on part of this rule, and if that 
part can be severed from the remainder of the rule, EPA may adopt as 
final those parts of the rule that are not the subject of an adverse 
comment.

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 action 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 action 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 action 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). This action 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 CAA. 
This action 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 state submissions, EPA's role is to approve state 
choices, provided that they meet the criteria of the CAA. 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 state submission for failure to use VCS. It would thus be 
inconsistent with applicable law for EPA, when it reviews a state 
submission, to use VCS in place of a state submission that otherwise 
satisfies the provisions of the CAA. 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 action does

[[Page 10382]]

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 May 7, 2007. 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).)
