Federal Implementation Plans for Iowa, Kansas, Michigan, Missouri, Oklahoma, and Wisconsin to Reduce Interstate Transport of Ozone

AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule (supplemental).
SUMMARY: In this supplemental notice of proposed rulemaking (SNPR), EPA is providing an opportunity for public comment on our conclusion that emissions from Iowa, Kansas, Michigan, Missouri, Oklahoma, and Wisconsin significantly contribute to downwind nonattainment or interfere with maintenance of the 1997 ozone National Ambient Air Quality Standards (NAAQS)in other states. EPA is also proposing Federal Implementation Plans (FIPs) to address a) the emissions identified as significantly contributing to nonattainment and interference with maintenance and b) the transport requirements with respect to the relevant NAAQS. EPA is proposing to implement the ozone season NOX program in the Transport Rule (Federal Implementation Plans to Reduce Interstate Transport of Fine Particulate Matter and Ozone in 27 States; Correction of SIP Approvals for 22 States) as the FIPs for Iowa, Kansas, Michigan, Missouri, Oklahoma, and Wisconsin to address the emissions identified as significantly contributing to nonattainment or interfering with maintenance with respect to the 1997 ozone NAAQS.

I. Today’s Proposal
In this supplemental notice of proposed rulemaking (SNPR), EPA is providing an opportunity for public comment on its conclusion that Iowa, Kansas, Michigan, Missouri, Oklahoma, and Wisconsin significantly contribute to nonattainment or interfere with maintenance of the 1997 ozone National Ambient Air Quality Standards (NAAQS) in other
states. In addition, EPA is proposing FIPs to address the transport requirements of the relevant NAAQS using programs*** E.O. 12866 Review – Draft – Do Not Cite, Quote, or Release During Review***

Page 8 of 36 created in the Transport Rule 1 that is being finalized simultaneously with this proposal. EPA is proposing to implement the ozone season NO X program in the Transport Rule as the FIPs for Iowa, Kansas, Michigan, Missouri, Oklahoma, and Wisconsin to address the emissions identified as significantly contributing to nonattainment or interfering with maintenance with respect to the 1997 ozone NAAQS. In the final Transport Rule, EPA identified and finalized FIPs for 20 states with emissions that significantly contribute to nonattainment or interfere with maintenance of the 1997 ozone NAAQS, 18 states with emissions that significantly contribute to nonattainment or interfere with maintenance of the 1997 annual PM 2.5 NAAQS, and 21 states with emissions that significantly contribute to nonattainment or interfere with maintenance of the 2006 24-hour PM 2.5 NAAQS. In this notice, EPA is taking comment only on a)its conclusions that the six states identified above have emissions that significant contribute to nonattainment and interfere with maintenance of the 1997 ozone NAAQS, and b)its decision to use the final Transport Rule programs as the FIPs to address these emissions in the six states. In this notice, EPA is not taking comment on any aspect of the final Transport Rule, including any aspect of the methodology used to identify receptors for nonattainment; the methodology used to identify receptors for maintenance; the

Page 9 of 36 methodology used to identify any specific state’s significant contribution and interference with maintenance; the methodologies used to establish state budgets, variability limits, and state assurance levels; or the methodologies used to allocate allowances to existing units, to establish new unit set-asides and Indian country new unit set-asides, or to allocate allowances in these set-asides. EPA provided an adequate opportunity for public comment on all of these issues during the comment period for the proposed Transport Rule and during the comment periods for the associated Notices of Data Availability (NODAs). 2 EPA received numerous comments on the proposed Transport Rule and on the associated NODAs and considered all comments received during the comment periods for these actions before finalizing the Transport Rule.

2 Notice of Data Availability Supporting Federal Implementation Plans to Reduce Interstate Transport of Fine Particulate Matter and Ozone (75 FR 53613; September 1, 2010). This NODA provided additional information on an updated version of the power sector modeling platform and data inputs EPA proposed to use to support the final Transport Rule. Notice of Data Availability Supporting Federal Implementation Plans to Reduce Interstate Transport of Fine Particulate Matter and Ozone: Revisions to Emission Inventories (75 FR 66055; October 27, 2010). Notice of Data Availability for Federal Implementation Plans to Reduce Interstate Transport of Fine Particulate Matter and Ozone: Request for Comment on Alternative Allocations, Calculation of Assurance Provision Allowance Surrender Requirements, New-Unit Allocations in Indian Country, and Allocations by States (76 FR 1109; January 7, 2011).*** E.O. 12866 Review – Draft – Do Not Cite, Quote, or Release During Review***

Page 10 of 36 EPA is also not taking comment on the emissions inventories used for the final Transport Rule modeling, including the emissions inventories for the six states identified above. EPA provided ample opportunity for comment on these inventories during the comment period for the proposed Transport Rule and the comment periods for the NODAs associated with that proposal. Inventories for all states included in the modeling domain were made available for public comment during that process. EPA made numerous changes to these inventories in response to public comments. Furthermore, the public had an incentive to comment on the inventories for these six states, not only because these inventories affect the modeling for all states in the modeling domain, but also because EPA was proposing to include all six states in at least one of the Transport Rule trading programs and the inventories were used for allocating the emissions allowances to covered units. EPA proposed to include Kansas and Michigan in the ozone-season NOX , annual
NOX , and annual SO 2 programs, proposed to include Oklahoma in the ozone-season NOX program, and proposed to include Iowa, Missouri and Wisconsin in the annual NOX and annual SO 2 programs. Commenters therefore had reason to look closely at the all of the emission data for all six states that EPA made available in the proposal and the NODAs.

A. EPA’s Authority for this Rule The statutory authority for this action is provided by the CAA, as amended, 42 U.S.C. § 7401 et. seq. Section 110(a)(2)(D) of the CAA, often referred to as the “good neighbor” provision of the Act, requires states to prohibit certain emissions because of their impact on air quality in*** E.O. 12866 Review – Draft – Do Not Cite, Quote, or Release During Review***

Page 11 of 36 downwind states. Specifically, it requires all states, within 3 years of promulgation of a new or revised NAAQS, to submit SIPs that prohibit certain emissions of air pollutants because of the impact they would have on air quality in other states. 42 U.S.C. § 7410(a)(2)(D). Section 301(a)(1) of the CAA gives the Administrator of EPA general authority to prescribe such regulations as are necessary to carry out her functions under the Act. 42 U.S.C. § 7601(a)(1). Section 110(c)(1) requires the Administrator to promulgate a FIP at any time within 2 years after the Administrator a)finds that a state has failed to make a required SIP submission or that such a submission is incomplete, or b) disapproves a SIP submission, unless the state corrects the deficiency and the Administrator approves the SIP revision. 42 U.S.C. § 7410(c)(1). Tribes are not required to submit state implementation plans. However, as explained in EPA’s regulations outlining Tribal Clean Air Act authority, EPA is authorized to promulgate FIPs for Indian country as necessary or appropriate to protect air quality if a tribe does not submit and get EPA approval of an implementation plan. See 40 CFR 49.11(a). For each FIP in this rule, except the FIP for Kansas, EPA either has found that the state has failed to make a required 110(a)(2)(D)(i)(I) SIP submission, or has disapproved a SIP submission. In addition, EPA has determined, in each case, that there has been no approval by the Administrator of a SIP submission correcting the deficiency prior to promulgation of the FIP. EPA’s obligation to promulgate a FIP arose when the finding of failure to submit or disapproval was made, and in no case has it been relieved of that obligation. The specific findings*** E.O. 12866 Review – Draft – Do Not Cite, Quote, or Release During Review***

Page 12 of 36 made and actions taken by EPA are described in greater detail in the TSD entitled “Status of CAA 110(a)(2)(D)(i)(I) SIPs: Supplemental Proposed Rule TSD,” which is available in the public docket for this rule. In addition, EPA has proposed a SIP Call under CAA 110(k)(5) for Kansas (76 FR 763, January 6, 2011), based on its conclusion that Kansas significantly contributes to nonattainment or interferes with maintenance of the 1997 ozone NAAQS. On March 9, 2007, EPA approved a 110(a)(2)(D)(i) SIP submission from the state of Kansas for the 1997 ozone and 1997 PM 2.5 NAAQS on March 9, 2007 (72 FR 10608). This SIP submission did not rely on compliance with the Clean Air Interstate Rule (CAIR) 3 to satisfy the requirements of 110(a)(2)(D)(i)(I). The analysis for the final Transport Rule, however, demonstrates that emissions from Kansas significantly contribute to nonattainment or interfere with maintenance of the 1997 ozone NAAQS in other states. Because the SIP does not prohibit these emissions, EPA is proposing to find it substantially inadequate to meet the requirements of 110(a)(2)(D)(i)(I) with respect to the 1997 ozone NAAQS. EPA has proposed to give Kansas 18 months to submit a SIP to correct this deficiency. EPA has also proposed to give Kansas the option of asking EPA to impose a FIP beginning in the 2012 ozone season. Any final action on the proposed SIP Call will be taken in a separate action, and will establish a deadline for submission of a new 110(a)(2)(D)(i)(I) SIP. In this action we are taking

Page 13 of 36 comment, with respect to Kansas, only on our conclusion that Kansas significantly contributes to nonattainment or interferes with maintenance of the 1997 ozone NAAQS and our proposal to use the Transport Rule ozone-season NOX program as the FIP for Kansas. We are not taking comment on issues related solely to the proposed SIP Call for Kansas.

B. Application of Methodologies to Identify Nonattainment and Maintenance Receptors and to Determine Significant Contribution and Interference with Maintenance In this SNPR, EPA is providing an opportunity for public comment on specific conclusions regarding emissions from six states that significantly contribute to nonattainment or interfere with maintenance of the 1997 ozone NAAQS. As noted above, EPA is not taking comment on the methodologies to identify nonattainment and maintenance receptors and to determine significant contribution and interference with maintenance with respect to the 1997 ozone NAAQS, which were finalized in the Transport Rule. Rather, we are accepting comment on the conclusion that application of these methodologies demonstrates that Iowa, Kansas, Michigan, Missouri, Oklahoma, and Wisconsin significantly contribute to nonattainment or interfere with maintenance of the 1997 ozone NAAQS in other states. i. Iowa The final Transport Rule determined that emissions from Iowa significantly contribute to nonattainment or interfere with maintenance of the annual PM 2.5 NAAQS and the 24-hour
PM 2.5 NAAQS. EPA also finalized FIPs to include Iowa in the Transport Rule annual NOX and annual SO 2 programs to address the transport requirements related to the annual and 24-hour*** E.O. 12866 Review – Draft – Do Not Cite, Quote, or Release During Review***

Page 14 of 36 PM 2.5 NAAQS. These conclusions are not being reviewed or reopened for public comment. The analysis for the final Transport Rule also identifies Iowa as a state that significantly contributes to nonattainment or interferes with maintenance only for a newly-identified 1997 ozone NAAQS maintenance receptor in Allegan County, MI. The methodology used to analyze significant contribution with respect to the 1997 ozone NAAQS, and its application to Iowa, is described in detail in the preamble to the final Transport Rule and in the TSDs entitled “Air Quality Modeling Final Rule TSD” and “Significant Contribution and State Emission Budgets Final Rule TSD,” which are available in the public docket for this rule. In this SNPR, EPA specifically requests comment on whether there are errors in the Agency’s application of the Transport Rule methodologies with respect to Iowa’s significant contribution to nonattainment and interference of the 1997 ozone NAAQS. ii. Kansas The final Transport Rule determined that emissions from Kansas significantly contribute to nonattainment or interfere with maintenance of the 24-hour PM 2.5 NAAQS. EPA also finalized FIPs to include Kansas in the Transport Rule annual
NOX and annual SO 2 programs to address the transport requirements related to the 24-hour PM 2.5 NAAQS. These conclusions are not being reviewed or reopened for public
comment. The analysis for the final Transport Rule also identifies Kansas as a state that significantly contributes to nonattainment or interferes with maintenance of the 1997 ozone NAAQS in another state. In its 2010 Transport Rule*** E.O. 12866 Review – Draft – Do Not Cite, Quote, or Release During Review***

Page 15 of 36 proposal, EPA proposed to determine that Kansas significantly contributes to or interferes with maintenance of the 1997 ozone NAAQS and also proposed to include Kansas in the Transport Rule ozone-season NOX program. In the analysis conducted for the final Transport Rule, however, Kansas is linked only to a newly identified ozone maintenance receptor in Allegan County, MI. The methodology used to analyze significant contribution with respect to the 1997 ozone NAAQS, and its application to Kansas, is described in detail in the preamble to the final Transport Rule and in the TSDs entitled “Air Quality Modeling Final Rule TSD” and “Significant Contribution and State Emission Budgets Final Rule TSD,” which are available in the public docket for this rule. In this SNPR, EPA specifically requests comment on whether there are errors in the Agency’s application of the Transport Rule methodologies with respect to Kansas’s significant contribution to nonattainment and interference of the 1997 ozone NAAQS. iii. Michigan The final Transport Rule determined that emissions from Michigan significantly contribute to nonattainment or interfere with maintenance of the annual and 24-hour PM 2.5 NAAQS. EPA also finalized FIPs to include Michigan in the Transport Rule annual NOX and annual SO 2 programs to address the transport requirements related to the annual and 24-hour

PM 2.5 NAAQS. These conclusions are not being reviewed or reopened for public comment. The analysis for the final Transport Rule also identifies Michigan as a state that significantly contributes to nonattainment or interferes with maintenance of the 1997 ozone NAAQS in another state. In its 2010 Transport Rule*** E.O. 12866 Review – Draft – Do Not Cite, Quote, or Release During Review***

Page 16 of 36 proposal, EPA proposed to determine that Michigan significantly contributes to or interferes with maintenance of the 1997 ozone NAAQS and also proposed to include Michigan in the Transport Rule ozone-season NOX program. In the analysis conducted for the final Transport Rule, however, Michigan is linked only to a newly identified ozone maintenance receptor in Harford County, MD. The methodology used to analyze significant contribution with respect to the 1997 ozone NAAQS, and its application to Michigan, is described in detail in the preamble to the final Transport Rule and in the TSDs entitled “Air Quality Modeling Final Rule TSD” and “Significant Contribution and State Emission Budgets Final Rule TSD,” which are available in the public docket for this rule. In this SNPR, EPA specifically requests comment on whether there are errors in the Agency’s application of the Transport Rule methodologies with respect to Michigan’s significant contribution to nonattainment and interference of the 1997 ozone NAAQS. iv. Missouri With regard to Missouri, the final Transport Rule determined that emissions from Missouri significantly contribute to nonattainment or interfere with maintenance of the annual PM 2.5 NAAQS and the 24-hour PM 2.5 NAAQS. EPA also finalized FIPs to include Missouri in the Transport Rule annual NOX and annual SO 2 programs to address the transport requirements related to the annual and 24-hour PM 2.5 NAAQS. These conclusions are not being reviewed or reopened for public comment. The analysis for the final Transport Rule also identifies Missouri as a state that significantly contributes to nonattainment or interferes with maintenance of the 1997*** E.O. 12866 Review – Draft – Do Not Cite, Quote, or Release During Review***

Page 17 of 36 ozone NAAQS in Harris County, TX, Brazoria County, TX, and Allegan County, MI. The methodology used to analyze significant contribution with respect to the 1997 ozone NAAQS, and its application to Missouri, is described in detail in the preamble to the final Transport Rule and in the TSDs entitled “Air Quality Modeling Final Rule TSD” and “Significant Contribution and State Emission Budgets Final Rule TSD,” which are available in the public docket for this rule, Docket ID No. EPA–HQ–OAR–2009–0491. In this SNPR, EPA requests comment specifically on whether there are errors in the Agency’s application of the Transport Rule methodologies with respect to Missouri’s significant contribution to nonattainment and interference of the 1997 ozone NAAQS. v. Oklahoma The final Transport Rule does not include any requirements that apply to sources in Oklahoma. The analysis conducted for the final Transport Rule, however, identifies Oklahoma as a state that significantly contributes to nonattainment or interferes with maintenance of the 1997 ozone NAAQS in Allegan County, MI. In its 2010 Transport Rule proposal, EPA proposed to determine that Oklahoma significantly contributes to or interferes with maintenance of the 1997 ozone NAAQS and also proposed to include Oklahoma in the Transport Rule ozone-season NOX program. In the analysis conducted for the final Transport Rule, however, Oklahoma is linked only to a newly identified ozone maintenance receptor in Allegan County, MI. The methodology used to analyze significant contribution with respect to the 1997 ozone NAAQS, and its application to Oklahoma, is described in detail in the preamble to the final Transport Rule and in the TSDs entitled “Air Quality Modeling Final*** E.O. 12866 Review – Draft – Do Not Cite, Quote, or Release During Review***

In this SNPR, EPA specifically requests comment on whether there are errors in the Agency’s application of the Transport Rule methodologies with respect to Oklahoma’s significant contribution to nonattainment and interference of the 1997 ozone NAAQS. vi. Wisconsin The final Transport Rule determined that emissions from Wisconsin significantly contribute to nonattainment or interfere with maintenance of the annual PM 2.5 NAAQS and the 24-hour PM 2.5 NAAQS. EPA also finalized FIPs to include Wisconsin in the Transport Rule annual NOX and annual SO 2 programs to address the transport requirements related to the annual and 24-hour PM 2.5 NAAQS. These conclusions are not being reviewed or reopened for public comment. The analysis for the final Transport Rule also identifies Wisconsin as a state that significantly contributes to nonattainment or interferes with maintenance only for a newly-identified 1997 ozone NAAQS maintenance receptor in Allegan County, MI. The methodology used to analyze significant contribution with respect to the 1997 ozone NAAQS, and its application to Wisconsin, is described in detail in the preamble to the final Transport Rule and in the TSDs entitled “Air Quality Modeling Final Rule TSD” and “Significant Contribution and State Emission Budgets Final Rule TSD,” which are available in the public docket for this rule.

C. Ozone Season NO X Emission Budgets for Six States In this SNPR, EPA is also presenting state ozone season
NOX emission budgets for covered units (generally large electric generating units) 4 in Iowa, Kansas, Michigan, Missouri, Oklahoma, and Wisconsin pertaining to the proposed FIPs for the 1997 ozone NAAQS. EPA will finalize these budgets, adjusted if necessary based on comments received, as part of the FIPs for these six states. As noted above, EPA is not taking comment on the methodologies used to establish state budgets, variability limits, or state assurance levels. Rather, in this section, we are requesting comment on the
state ozone season NO X emission budgets calculated using these methodologies. These budgets are presented in Table I.C-1. The associated variability limits and state assurance levels are presented in Table I.C-2.

The TSD entitled “Proposed Unit-Level Ozone Season NOX Allowance Allocations to Existing Units in Six States: Supplemental Proposed Rule TSD” also describes how to access publicly available downloadable Excel spreadsheets with the proposed unit-level allowance allocations and the supporting data EPA used in applying the final Transport Rule existing unit allocation methodology to eligible units in each of the named states in this SNPR on the Web at http://www.epa.gov/airtransport

. EPA is taking comment only on the data inputs (e.g., corrections to the heat input value used for any particular unit) used in applying the allowance allocation methodology for existing units and on the resulting existing-unit allocations that we are proposing for the six states involved. EPA provided ample opportunity for comment on the methodologies used for allowance allocation and for establishing the set-asides both in the public comment period following the rule proposal and through the January 7, 2011
NODA. As discussed in section VII.D.1, “Allocations to Existing Units” of the preamble to the final Transport Rule, EPA has carefully evaluated and responded to numerous comments on this issue. These public comments were taken into account when finalizing the Transport Rule. 5

5EPA made some corrections to heat input data based on comments received from sources correcting such data.*** E.O. 12866 Review – Draft – Do Not Cite, Quote, or Release During Review***

Page 22 of 36 EPA is proposing that new unit set-asides for allowance allocations to new units be created and implemented for each of these six states in the same manner as for the other states covered in the Transport Rule ozone season NO X program. This approach is described in section VII.D.2, “Allocations to New Units,” of the preamble to the final Transport Rule. Table I.D-1 shows the proposed new allocation percentages for ozone season NO X allowances for Iowa, Kansas, Michigan, Missouri, Oklahoma, and Wisconsin. As noted above, EPA is taking comment only on the application of the new unit set-aside methodology to these states and on the resulting set-asides that we are proposing (i.e., whether the percentages for the set-asides are calculated properly). EPA provided ample opportunity for comment on the new unit set-aside methodology in the public comment period following the rule proposal.

Page 23 of 36 states included in this SNPR which have areas of Indian country within their boundaries. Under the final TransportRule, EPA will administer these Indian country new unit setasides regardless of whether a state replaces its Transport Rule FIP with an approved SIP. EPA is proposing to use the same mechanism for the states covered in this SNPR. EPA is taking comment only on the application of the Indian country new unit set-aside methodology to these states and on the resulting set-asides that we are proposing. EPA provided ample opportunity for comment on the methodologies for Indian country new unit set-asides through the January 7, 2011 NODA.

F. Implementation EPA is proposing that implementation of emission requirements for the six states addressed in this SNPR be identical to those for the other states covered by the Transport Rule ozone season NO X program. Refer to section IV.C-2, “FIP Authority for Each State and NAAQS Covered,” in the preamble to the final Transport Rule for a general discussion of EPA’s legal responsibility and authority to impose Federal Implementation Plans (FIPs) in certain circumstances where State Implementation Plans (SIPs) are*** E.O. 12866 Review – Draft – Do Not Cite, Quote, or Release During Review***

Page 24 of 36 deficient. The TSD entitled “Status of CAA 110(a)(2)(D)(i)(I) SIPs: Supplemental Proposed Rule TSD” identifies actions taken by EPA with respect to the 110(a)(2)(D)(i)(I) SIP requirements for the named states with respect to the relevant NAAQS. This TSD demonstrates that EPA has authority and a legal obligation to promulgate each FIP proposed in this SNPR. To be consistent and synchronize with the other states covered by the Transport Rule ozone season NOX program, EPA has not adjusted the timing for compliance with the Transport Rule programs for these states. 6 EPA expects to finalize this rulemaking on or before November 1, 2011; the ozone season for 2012 does not begin until May 1, 2012. This will allow an approximately six-month lead time before the start of the 2012 ozone season. The vast majority of covered sources already have combustion controls installed; therefore, EPA expects that only a small number of sources will need to install combustion controls to comply, and the total number of installations is practical to achieve within the time period for additional construction. Individual sources may comply through other measures (such as purchasing additional allowances) in the event that it takes a

6 As explained in the TSD, EPA proposed a SIP call requiring Kansas to address its deficiency for the 1997 Ozone NAAQS 110(a)(2)(D)(i)(I) requirements (76 FR 763). EPA intends to finalize the SIP call concurrent with the finalization of this action. This will enable Kansas to use the same remedy as the other states covered by the final Transport Rule ozone season NOX program. (Specifically, Kansas may request--through a letter submitted to EPA within three weeks of the final SIP call--that the Kansas ozone FIP be implemented at the same time as the other states.)*** E.O. 12866 Review – Draft – Do Not Cite, Quote, or Release During Review***

Page 25 of 36 particular source more than six months for installation of a given combustion control. EPA’s rationale for determining that this lead time is sufficient is described in detail in section VII.C “Compliance Deadlines” of the preamble to the final Transport Rule. EPA is also not proposing to alter the compliance deadlines or deadlines for submission of SIPs to replace the ozone FIPs for these six states. The submission deadlines and process for the six states covered by this SNPR, as well as the rationale behind them, can be found in section X “Transport Rule State Implementation Plans” of the preamble to the final Transport Rule.

F. Expected Effects of the Proposed Action This proposal is projected to limit ozone season NO X emissions in Iowa, Kansas, Michigan, Missouri, Oklahoma, and Kansas beginning in 2012. The impacts of the Transport Rule inclusive of this proposal are discussed in section VIII of the preamble to the final Transport Rule. Table VIII-A.5 shows the state-by-state ozone season NO X emissions reductions (compared to the base case) expected in both 2012 and 2014. Overall ozone improvements, including these states and others, are displayed in Table VIII-B-2 and are discussed in greater detail in the Air Quality Modeling Final Rule

II. Statutory and Executive Order Reviews
A. Executive Order 12866: Regulatory Planning and Review and Executive Order 13563: Improving Regulation and Regulatory Review
Under Executive Order 12866 (58 FR 51735, October 4, 1993), the Agency must determine whether a regulatory action is "significant" and therefore subject to Office of Management and Budget (OMB) review and the requirements of the Executive Order. The Order defines "significant regulatory action" as one that is likely to result in a rule that may: 1. Have an annual effect on the economy of $100 million or more or adversely affect in a material way the economy, a sector of the economy, productivity, competition, jobs, the environment, public health or safety, or State, local, or Tribal governments or communities; 2. Create a serious inconsistency or otherwise interfere with an action taken or planned by another agency; 3. Materially alter the budgetary impact of entitlements, grants, user fees, or loan programs or the rights and obligations of recipients thereof; or 4. Raise novel legal or policy issues arising out of legal mandates, the President's priorities, or the principles set forth in the Executive Order. In view of its important policy implications and potential effect on the economy of over $100 million, the Transport Rule program inclusive of this proposal has been judged to be an economically “significant regulatory action”*** E.O. 12866 Review – Draft – Do Not Cite, Quote, or Release During Review***

Page 27 of 36 within the meaning of the Executive Order. Accordingly, EPA submitted the final Transport Rule and this SNPR to OMB for review under EO 12866 and EO 13563 (76 FR 3821, January 21, 2011). In addition, EPA prepared an analysis of the potential costs and benefits for the Transport Rule program inclusive of this proposal. This analysis is contained in the Regulatory Impact Analysis (RIA) for the Transport Rule. The RIA available in the docket describes in detail the empirical basis for EPA’s assumptions and characterizes the various sources of uncertainties affecting the estimates below. In doing this, EPA adheres to EO 13563, “Improving Regulation and Regulatory Review,” (76 FR 3,821, January 21, 2011), which is a supplement to EO 12866. For additional information on how EPA’s benefit-cost analyses conform to the requirements of EO 13563, please see section XII.A of the preamble to the final Transport Rule. EPA believes that there is no impact to the economy beyond that which is reported in the final Transport Rule.

1. What Economic Analyses Were Conducted for the Rulemaking? The analyses conducted for the Transport Rule program inclusive of this proposal provide several important analyses of impacts on public welfare. These include an analysis of the social benefits, social costs, and net benefits of the regulatory scenario. The economic analyses also address issues involving small business impacts, unfunded mandates (including impacts for Tribal governments), and energy impacts.*** E.O. 12866 Review – Draft – Do Not Cite, Quote, or Release During Review***

Page 28 of 36 2. What Are the Benefits and Costs of the Transport Rule Program?

The benefit-cost analysis shows that substantial net economic benefits to society are likely to be achieved due to reduction in emissions and improvements in ozone and PM 2.5 ambient concentrations resulting from the Transport Rule program inclusive of this proposal. For more information on the costs and benefits for the Transport Rule program inclusive of this proposal, please refer to Table VIII.C-4 of the preamble to the final Transport Rule.

B. Paperwork Reduction Act EPA is required to document the information collection burden imposed by the Transport Rule program on industry, States, and EPA in an information collection request (ICR). The ICR describes the information collection requirements associated with the final Transport Rule program inclusive of this proposal and estimates the incremental costs of compliance with all such requirements, such as the requirement for industry to monitor, record, and report emissions data to EPA. The ICR for the Transport Rule Program inclusive of this proposal has been submitted for approval to OMB under the Paperwork Reduction Act, 44 U.S.C. 3501 et seq., and the information collection requirements it documents are not enforceable until such approval has been granted. An ICR was also submitted to OMB in support of the proposed Transport Rule; no adverse comment was received by EPA on either the information collection requirements or their associated cost estimates as described in that document.*** E.O. 12866 Review – Draft – Do Not Cite, Quote, or Release During Review***

Page 29 of 36 EPA believes that there are no information collection requirements or burden beyond those reported in the Transport Rule program inclusive of this proposal.

C. Regulatory Flexibility Act The Regulatory Flexibility Act (RFA) generally requires an agency to prepare a regulatory flexibility analysis of any rule subject to notice and comment rulemaking requirements under the Administrative Procedure Act or any other statute 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 organizations, and small governmental jurisdictions.
After considering the economic impacts of the Transport Rule program inclusive of this proposal on small entities, as described in section XII.C of the preamble to the final Transport Rule, EPA certifies that this action will not have a significant economic impact on a substantial number of small entities (No SISNOSE). This certification is based on the economic impact of the final Transport Rule and this proposal if finalized on all affected small entities across all industries affected. EPA believes that the provisions of the Regulatory Flexibility Act are covered by and reported in section XII.C of the preamble to the final Transport Rule.

D. Unfunded Mandates Reform Act Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), 2 U.S.C. 1531-1538, requires federal agencies, unless otherwise prohibited by law, to assess the effects of their regulatory actions on state, local, and tribal governments and the private sector. The Transport Rule program inclusive*** E.O. 12866 Review – Draft – Do Not Cite, Quote, or Release During Review***

Page 30 of 36 of this proposal contains a Federal mandate that may result in expenditures of $100 million or more for state, local, and tribal governments, in the aggregate, or the private sector in any one year. Accordingly, EPA has prepared under section 202 of the UMRA a written statement that is summarized in section XII.D of the preamble to the final Transport Rule. Consistent with the intergovernmental consultation provisions of section 204 of the UMRA, EPA held consultations with the governmental entities affected by the final Transport Rule and this proposal if finalized. As detailed in section XII.D of the preamble to the final Transport Rule, EPA participated in informational calls with the Environmental Council of the States (ECOS) and the National Governors Association to provide information about the January 7, 2011 NODA 8 directly to state and local officials and conducted consultations with federally recognized tribes prior to finalizing the final Transport Rule and issuing this SNPR for inclusion of six additional states (of which five—- Iowa, Kansas, Michigan, Oklahoma, and Wisconsin—-have Indian country within their boundaries). EPA believes that no unfunded mandates have been created by the Transport Rule program inclusive of this proposal. Neither the final Transport Rule nor the provisions in this SNPR have regulatory requirements that might significantly or uniquely affect small governments.

E. Executive Order 13132: Federalism As described in section XII.E of the preamble to the final Transport Rule, EPA has concluded that the Transport

8 76 FR 1109 (January 7, 2011).*** E.O. 12866 Review – Draft – Do Not Cite, Quote, or Release During Review***

Page 31 of 36 Rule program inclusive of this proposal does not have federalism implications. Thus, Executive Order 13132 does not apply to the final Transport Rule or to this SNPR.

F. Executive Order 13175: Consultation and Coordination with Indian Tribal Governments Under Executive Order 13175 (65 FR 67249, November 9, 2000), EPA may not issue a regulation that has tribal implications, that imposes substantial 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 tribal governments, or EPA consults with tribal officials early in the process of developing the proposed regulation and develops a tribal summary impact statement. As described in section XII.F of the preamble to the final Transport Rule, EPA believes that there has been proper consultation and coordination with Indian tribal governments for the Transport Rule program inclusive of this proposal. As required by section 7(a) of the Executive Order, EPA’s Tribal Consultation Official has certified that the requirements of the Executive Order have been met in a meaningful and timely manner. A copy of the certification is included in the docket for the final Transport Rule.

G. Executive Order 13045: Protection of Children from Environmental Health and Safety Risks Executive Order 13045 (62 FR 19,885, April 23, 1997) applies to any rule that: 1) is determined to be “economically significant” as defined under EO 12866, and 2) concerns an environmental health or safety risk that EPA has reason to believe may have a disproportionate effect on*** E.O. 12866 Review – Draft – Do Not Cite, Quote, or Release During Review***

Page 32 of 36 children. If the regulatory action meets both criteria, the Agency must evaluate the environmental health or safety effects of this planned rule on children, and explain why this planned regulation is preferable to other potentially effective and reasonably feasible alternatives considered by the Agency. As described in section XII.G of the preamble to the final Transport Rule, the Transport Rule program inclusive of this proposal is not subject to Executive Order 13045 because it does not involve decisions that increase environmental health or safety risks that may disproportionately affect children. The EPA believes that the emissions reductions from the strategies in the Transport Rule program inclusive of this proposal will further improve air quality and will further improve children’s health.

H. Executive Order 13211: Actions that Significantly Affect Energy Supply, Distribution, or Use Executive Order 13211 (66 FR 28355, May 22, 2001) provides that agencies shall prepare and submit to the Administrator of the Office of Regulatory Affairs, OMB, a Statement of Energy Effects for certain actions identified as “significant energy actions.” Section 4(b) of Executive Order 13211 defines “significant energy action” as “any action by an agency (normally published in the Federal Register ) that promulgates or is expected to lead to the promulgation of a final rule or regulation, including notices of inquiry, advance notices of proposed rulemaking, and notices of proposed rulemaking: (1) (i) that is a significant regulatory action under Executive Order 12866 or any successor order, and (ii) is likely to have a significant adverse effect on the supply, distribution, or use of energy;*** E.O. 12866 Review – Draft – Do Not Cite, Quote, or Release During Review***

Page 33 of 36 or (2) that is designated by the Administrator of the Office of Information and Regulatory Affairs as a significant energy action.” This rule is a significant regulatory action under Executive Order 12866, and this rule is likely to have a significant adverse effect on the supply, distribution, or use of energy. EPA prepared a Statement of Energy Effects for the transport Rule program inclusive of this proposal which appears in section XII.H of the preamble to the final Transport Rule.
EPA believes that there is no impact to the energy supply beyond that which is reported for the Transport Rule program inclusive of this proposal in the final Transport Rule.

I. National Technology Transfer Advancement Act Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (‘‘NTTAA’’), Public Law 104–113, 12(d) (15 U.S.C. 272 note) directs EPA to use voluntary consensus standards in its regulatory activities unless to do so would be inconsistent with applicable law or otherwise impractical. Voluntary consensus standards are technical standards (e.g., materials specifications, test methods, sampling procedures, and business practices) that are developed or adopted by voluntary consensus standards bodies. NTTAA directs EPA to provide Congress, through OMB, explanations when the Agency decides not to use available and applicable voluntary consensus standards. As described in section XII.I of the preamble to the final Transport Rule, the Transport Rule program inclusive of this proposal will require all sources to meet the applicable monitoring*** E.O. 12866 Review – Draft – Do Not Cite, Quote, or Release During Review***

Page 34 of 36 requirements of 40 CFR part 75. Part 75 already incorporates a number of voluntary consensus standards.

J. Executive Order 12898: Federal Actions to Address Environmental Justice in Minority Populations and Low-Income Populations
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, low-income, and Tribal populations in the United States. During development of this Transport Rule program inclusive of this proposal, EPA considered its impacts on low-income, minority, and tribal communities in several ways and provided multiple opportunities for these communities to meaningfully participate in the rulemaking process. As described in section XII.J of the preamble to the final transport Rule, EPA believes that the final remedy in the Transport Rule program inclusive of this proposal addresses potential environmental justice concerns about localized hot spots and reduces ambient concentrations of pollution where they are most needed by sensitive and vulnerable populations. EPA believes that the vast majority of communities and individuals in areas covered by the Transport Rule program inclusive of this proposal, including numerous low-income, minority, and tribal individuals and communities in both rural areas and inner cities in the eastern and central U.S.,*** E.O. 12866 Review – Draft – Do Not Cite, Quote, or Release During Review***

Page 35 of 36 will see significant improvements in air quality and resulting improvements in health. EPA’s assessment of the effects of the final Transport Rule program inclusive of this proposal on these communities is detailed in section XII.J of the preamble to the final Transport Rule. Based on this assessment, EPA concludes that we do not expect disproportionately high and adverse human health or environmental effects on minority, low-income, or tribal populations in the United States as a result of implementing the Transport Rule program inclusive of this proposal.*** E.O. 12866 Review – Draft – Do Not Cite, Quote, or Release During Review***
