1 SIP Development Process Overview For Hickory Transportation Partners Requirements, Scenarios and Timelines Laura Boothe, NCDAQ Mike Abraczinskas, NCDAQ Eddie Dancausse, FHWA February 8, 2005

2 Outline Background on PM2.5 standard General PM2.5 timeline Whats a SIP? Scenarios –Redesignation/Maintenance SIP Requirements vs. –Attainment Demonstration SIP Requirements

3 Background Annual PM2.5 standard –If a monitored design value is > 15.0 µg/m 3, that monitor is violating the annual standard –The design value is defined as: Annual mean concentration, averaged over 3 years

4 Human Hair (70 µm diameter) Hair cross section (70 m) PM 2.5 (2.5 µm) PM 10 ( 10µm ) M. Lipsett, California Office of Environmental Health Hazard Assessment A complex mixture of extremely small particles and liquid droplets Particulate Matter: What is It?

5 Public Health Risks Are Significant Particles are linked to: Premature death from heart and lung disease Aggravation of heart and lung diseases –Hospital admissions –Doctor and ER visits –Medication use –School and work absences And possibly to –Lung cancer deaths –Infant mortality –Developmental problems in children, such as low birth weight

8 North Carolina Areas Designated Nonattainment for PM2.5 (EPA 12/17/04)

9 Hickory PM2.5 Design Values Monitor Hickory County Catawba 01-03 15.5

10 PM2.5 Nonattainment Timeline Immediate (April 5, 2005) –New source review One year –Transportation conformity Three years –State Implementation Plan (SIP) – attainment demonstration Five years (or as expeditiously as practicable) –Attain standard (Hickory & Triad)

11 PM2.5 Nonattainment Timeline Definitions for Hickory Area Effective date = Transportation conformity date = SIP submittal date = Attainment date = Data used to determine attainment = (Modeling) Attainment year = Redesignation base years = Maintenance years = April 5, 2005 April 5, 2006 April 5, 2008 April 5, 2010* 2007-2009 2009* 2005 or 2006 TBD * Or as early as possible

12 State Implementation Plan (SIP) Need a SIP submittal to EPA within three years –Attainment Demonstration that details the States plan to bring the area into attainment of the Federal standard Significant emission controls are already underway –Clean Smokestacks Act –Vehicle emissions testing –Ultra-Low sulfur fuels –Cleaner Engines

13 2 Scenarios are possible Redesignation/Maintenance SIP Attainment Demonstration SIP

14 Scenario Overviews Redesignation/Maintenance SIP –If area attains standard prior to attainment demonstration submittal date (April 5, 2008) –Package containing emissions estimates for the year the area came into attainment and maintenance years –Requires data for the year the area came into attainment and maintenance years Attainment Demonstration SIP –Submittal 3 years after effective date (April 5, 2008) –Based on comprehensive modeling –Requires data for only the attainment year (2009)

15 Redesignation/Maintenance SIP Process Overview Area attains standard (2005 or 2006) –Develop emissions inventory for the year area attains standard –Develop maintenance emissions inventories for at least 10 years beyond redesignation approval Determined through Inter-Agency Consultation Process –Develop interim/maintenance emissions inventories 3 to 5 year increments –Compare maintenance emissions to attaining years emissions Maintenance emissions must be lower than attaining years emissions… If not, control strategies must be developed –Or use modeling

16 Redesignation/Maintenance SIP Process Overview Develop draft SIP package –Emissions comparisons –Motor Vehicle Emissions Budgets –Contingency measures Take draft SIP to public hearing –30 day comment period Submit to EPA anytime prior to April 2008 Update plan 8 years after redesignation –Must examine additional 10 years beyond final maintenance year in redesignation package

17 Redesignation/Maintenance SIP Example Timeline End of 2005 -> examine PM2.5 data –If the area attains 2005 and maintenance years (e.g. 2007, 2010, 2013, 2016) data needed for emissions estimates/comparisons –VMT and speeds Contingency measures –NCDAQ define triggers and follow-up actions. Set motor vehicle emissions budgets –Consultation process… What years? –Safety margins? Public hearing Request expeditious redesignation back to attainment/maintenance –Redesignation could be final as early as summer 2006 –Conformity due 18 months after approval of Redesignation SIP

18 Redesignation/Maintenance SIP Example Timeline End of 2005 -> examine PM2.5 data –If the area does not attain Must start modeled attainment demonstration Review 2006 PM2.5 data –Possibly start redesignation package

19 Redesignation/Maintenance SIP Requirements of transportation partners VMT and speeds for attaining year and maintenance years Participate in stakeholder meetings Provide input on additional strategies (if needed) and contingency measures Decision on how Motor Vehicle Emissions Budgets are set Review package during public comment period

20 Attainment Demonstration SIP Process Overview Modeling Attainment year = 2009 –Attainment date April 5, 2010 Develop emissions inventory –2002 inventories –2009 attainment year inventory Comprehensive modeling for 2002 and 2009 –Modeling full year –Must pass the USEPA modeled attainment test –If not, additional control strategies must be developed and modeled

21 Attainment Demonstration SIP Process Overview Clean Air Act requirement for Basic areas –Reasonable Available Control Measures (RACM) Develop draft SIP package –Motor Vehicle Emissions Budgets for attainment year –Contingency measures Take draft SIP to public hearing –30 day comment period Submit to EPA by April 2008

22 Attainment Demonstration SIP Example Timeline Base year modeling underway –Collected (in 2004) VMT and speed data for 2002 Future year modeling will start Spring 05 –2009 VMT and speed data needed –Have needs of RACM been met? Awaiting further guidance from USEPA Future year emissions and air quality modeling

23 Attainment Demonstration SIP Example Timeline Must pass the USEPA modeled attainment test –If not, additional control strategies must be developed and modeled Develop draft SIP package –Motor Vehicle Emissions Budgets for attainment year –Contingency measures Take draft SIP to public hearing –30 day comment period Submit to EPA by April 2008

24 Attainment Demonstration SIP Requirements of transportation partners VMT and speeds for modeled attainment year Participate in stakeholder meetings –Technical update meetings –RACM development –Provide input on additional strategies (if needed) and contingency measures –Decision on how Motor Vehicle Emissions Budgets are set Review package during public comment period

25 VMT and Speeds Attainment Demonstration (2009) –March 2005 Redesignation (2005/2006 & maintenance years) –October 2005 or October 2006

26 Stakeholder Meetings NCDAQ will host periodic technical updates on process –Spring and Fall 2005 at minimum NCDAQ will host consultation meeting(s) on control strategy development (if needed) and contingency measures RACM (if needed) Will announce @ SICM meetings

27 Review of SIP Package 30-45 days once package is made public Will announce @ SICM meetings

28 New Standards? EPA has reviewed the PM2.5 standards –EPA Staff Paper - Draft out for comment 15 µg/m 3 annual standard 25-35 µg/m 3 - 24-hr standard (99 th percentile) Or 12-14 µg/m 3 annual standard 35-40 µg/m 3 - 24-hr standard (99 th percentile)

29 New Standards? Fine Particulate (tentative schedule) October 2004Criteria Document December 2005EPA proposes New Standard September 2006EPA Finalizes New Standard September 2008EPA Promulgates September 2011States Submit SIPs
