Designation Criteria Nonattainment Monitoring data or modeling results shows a violation of the standard Attainment Both monitoring data and modeling results showing no violation of the standard Unclassifiable All other areas 32 SO2 SIP Development Process • IDEM prefers a single SIP development process to meet all obligations since both maintenance SIP and attainment SIP require modeling and rulemaking. – Addresses all obligations. – Conserve resources. – Ensure timely SIP submittals. – Eliminate confusion associated with rulemaking for emission limitations or controls. – Reduce the burden of additional monitoring. 33 SO2 Modeling Protocol • Model Fountain and Warrick counties. These two counties currently monitor nonattainment, but should monitor attainment following the installation of Flue-Gas Desulfurization scrubbers (FGDs) at sources in those counties. • Model those areas that currently show attainment through monitoring data (Lake, Porter, LaPorte, Jasper, Hendricks and Vanderburgh counties). • Model those areas (Marion and Gibson counties) which show a downward trend in SO2 emissions, still monitor violations, but may reach attainment in the near future. • Based on results from the above modeling, Indiana will prioritize the remaining sources greater than 100 tons per year and model starting with the largest source or cluster of sources. • Areas that measure air quality above the standard and are not expected to attain in the near future will not be modeled until Indiana is ready to draft attainment SIPs. 34 Transport Rule 35 Proposed Clean Air Transport Rule • • • • • Clean Air Interstate Rule (CAIR) remains in place until the proposed transport rule is finalized. Affects power plants because their emission reductions are most costeffective. Twenty-one states (including Indiana) will be controlled for precursors of both fine particles and ozone. – Eight states will be controlled for fine particles only and 4 states will be controlled for ozone only. Separate requirements for annual SO2 reductions, NOx reductions, ozone-season NOx reductions, and also sets emissions budgets for each state. To meet the proposed rule, U.S. EPA anticipates power plants will operate already installed control equipment more frequently, use lower sulfur coal, or install pollution control equipment. 36 Proposed Clean Air Transport Rule • • • • • By 2014 the benefits include 71% reduction from 2005 levels in SO2 and 52% reduction from 2005 levels in NOx emissions from power plants. – 6.3 million tons of SO2 per year. – 1.4 million tons of NOx per year. • 300,000 tons of NOx during ozone season. SO2 emissions would be limited to 2.6 million tons per year (tpy). NOx emissions would be limited to 1.3 million tpy. – Ozone season NOx emissions will be limited to 600,000 tpy. U.S. EPA estimates the annual benefits from the proposed rule range between $120-$290 billion in 2014. U.S. EPA estimates annual compliance costs to the power sector at $2.8 billion in 2014. 37 Proposed Clean Air Transport Rule • U.S. EPA is proposing one approach and taking comment on two alternatives. All three approaches would cover the same states, set budgets for each state, and obtain the reductions from power plants. – U.S. EPA’s preferred approach: allows interstate trading and limited interstate trading among power plants but assures that each state will meet its pollution control obligations. – First alternative: trading is allowed only among power plants within a state. – Second alternative: U.S. EPA specifies the allowable emission limit for each power plant and allows some averaging of emission rates. 38 Proposed Clean Air Transport Rule • Proposal includes four separate control regions: – NOx reductions (2012). – Ozone-season NOx reductions (2012). – Annual SO2 reductions. • Phase I (2012) and Phase II (2014). • Two control groups. – Group 1: 2012 cap lowers in 2014. – Group 2: 2012 cap only. • Indiana is in Group 1. – NOx annual and ozone season. – SO2 annual. 39 Clean Air Interstate Rule (CAIR) Compared to Clean Air Transport Rule (CATR) (Units in Tons) NOx Ozone Season CAIR Phase 1 CAIR Phase 2 CATR CATR 2009-2014 2015 and Later 2012-2013** 2014 and Later** 45,952 39,773 49,987 49,987 NOx Annual 108,935 90,779 115,687 115,687 SO2 Annual 254,599* 178,219* 400,378 201,412 SO2 budget is approximate.

Requires reporting of annual GHG emissions directly to U.S. EPA. Does not require control of GHG emissions. Third party verification of emissions data not required. U.S. EPA estimates around 10,000 facilities are affected: – 25 source categories. – 5 types of suppliers of fuel and industrial GHGs. – Motor vehicle and engine manufacturers (except light duty sector). • Emission reporting thresholds of 25,000 metric tons or more of carbon dioxide equivalent (CO2e) per year for most sources. • Facilities and suppliers to begin collecting data on January 1, 2010. • First emissions report due on March 1, 2011. 53 GHG Mandatory Reporting Rule (continued) • Requires motor vehicle and engine manufacturers to begin reporting carbon dioxide for model year 2011 and other GHGs in subsequent model years. • Facilities subject to the Acid Rain Program required to continue submitting quarterly reports, in addition to providing annual GHG reports. • Federal rule does not preempt states from regulating or requiring reporting of GHGs. • No state delegation. • IDEM can access verified emissions data from U.S. EPA. • Sources no longer required to report if they fall below specific emission thresholds. 54 Prevention of Significant Deterioration (PSD) and Title V GHG Tailoring Rule • • Final rule published on June 3, 2010 (75 FR 31514). Sets thresholds for GHG emissions under PSD and Title V for new and existing industrial facilities. – “Tailors” the PSD and Title V requirements to limit number of facilities required to obtain PSD and Title V permits for GHGs. • Close to 70% of GHG emissions from stationary sources nationally will be subject to this rule (e.g. power plants, refineries, cement production). – Establishes tiered schedule: • Largest sources with the most CAA permitting experience first. • Adds large sources of GHGs not previously covered for other pollutants. – Emissions from small farms, restaurants, and all but very large commercial facilities not covered at this time. 55 Prevention of Significant Deterioration (PSD) and Title V GHG Tailoring Rule (continued) • Existing CAA permitting program emissions thresholds of 100 and 250 tons per year (tpy) not feasible for GHGs as they are emitted in much higher volumes. • Existing thresholds would take effect automatically for GHGs on January 2, 2011 without the tailoring rule resulting in a dramatic increase in number of required PSD and Title V permits. 56 Prevention of Significant Deterioration (PSD) and Title V GHG Tailoring Rule (continued) • Covered Pollutants: – Carbon Dioxide – Methane – Nitrous Oxide – Hydrofluorocarbons – Perfluorocarbons – Sulfur Hexafluroride • Carbon dioxide equivalents (CO2e) used to address differences in global warming potentials for each GHG. 57 Prevention of Significant Deterioration (PSD) and Title V GHG Tailoring Rule (continued) • Implementation: – January 2, 2011 – June 30, 2011: • Only applies to new construction or modification projects currently subject to the PSD or Title V permitting programs. • Increase of net GHG emissions by at least 75,000 tpy CO2e, requires BACT for GHG emissions. • No sources become subject solely due to GHG emissions. 58 Prevention of Significant Deterioration (PSD) and Title V GHG Tailoring Rule (continued) • Implementation: – July 1, 2011 – June 30, 2013 • Applies to new construction projects that emit GHG emissions of at least 100,000 tpy CO2e even if not subject to PSD for another pollutant. • Modifications at existing facilities that increase GHG emissions by at least 75,000 tpy CO2e even if no other pollutant significantly increases. • Sources emitting at least 100,000 tpy CO2e subject to Title V. • Nationally, about 550 new Title V sources due to GHGs (mostly large solid waste landfills, coal mines, oil and gas production, and large industrial sources) and about 900 additional PSD permit actions from increases in GHG emissions. 59 Prevention of Significant Deterioration (PSD) and Title V GHG Tailoring Rule (continued) • Implementation: – January 2011 – July 1, 2012 • U.S. EPA plans to initiate another rulemaking on additional steps for phasing in GHG permitting and streamlining future GHG permitting. • No permits for sources with less than 50,000 tpy CO2e emissions until at least April 30, 2016. • U.S. EPA will complete study on remaining GHG permitting burdens if applied to small sources by April 30, 2015. • U.S. EPA working on additional information and guidance in 2010. 60 State Implementation Plan Considerations • U.S. EPA is delaying final action on issuing limited approvals for SIPapproved PSD and Title V programs until it better understands how states plan to implement tailoring rule. • U.S. EPA requested states submit information by August 2, 2010, to address the following: – Will State apply the meaning of term “subject to regulation” for both PSD and Title V? – If yes, will State use regulatory or legislative process? – If revising statutes or rules, what is estimated schedule? • Indiana submitted information on July 23, 2010. – Intend to implement GHG tailoring approach through interpretation of the meaning of “subject to regulation.” 61 Tailoring Indiana’s Rules • Indiana’s PSD and Title V rules must be revised for consistency with GHG applicability thresholds and definitions in final federal rule. – Current permitting thresholds are 100 and 250 tons. – Any GHG emissions increase is significant under current rules and subject to more stringent permitting requirements • Expedited rulemaking to address federal tailoring approach. – Section 8 Notice published – mid-August 2010. – 30-day comment period end date – mid-September 2010. – Final rule adopted – November 2010. – Rule effective date – March 2011. – Emergency rule as interim measure may be considered. 62 Tailoring Indiana’s Rules (continued) • Conducting detailed analysis of permitting rules to determine if additional revisions and clarifications are necessary. – Emissions Reporting requirements in 326 IAC 2-6. – Permitting Fees for GHGs. – Permit Applicability issues. • Rulemaking to address outcomes from a refined evaluation will be initiated in early 2011. 63 Office of Air Quality Contact Information Scott Deloney Branch Chief [email protected] (317) 233-5694 Christine Pedersen Section Chief [email protected] (317) 233-5684 Sarah Raymond Senior Environmental Manager [email protected] (317) 232-8449 64
