  1. AIR QUALITY Issues in the Columbus Region Columbus City Council July 24, 2007

  2. Introduction: The Clean Air Act • Federal law, but jointly enforced by states • EPA sets limits on how much of a pollutant can be present in the air • States have to develop state implementation plans (SIPs) that describe how they will address air pollution issues • Effects not just Columbus, but the region as a whole

  3. Background: Air Pollutants Clean Air Act regulates six criteria pollutants: • Particulate Matter (PM) • Nitrogen oxides • Sulfur dioxide • Lead • Ozone • Carbon monoxide

  4. Background: What Is Particulate Matter? • Mixture of extremely small solids and liquid droplets suspended in air • PM may include soil and dust particles, smoke, metals, acids, and organic chemicals • PM10 is coarse particulate matter – visible deposits of soot • PM2.5 is fine particulate matter – microscopic particles about 1/30 the diameter of a human hair

  5. PARTICULATE MATTER A complex mixture of extremely small particles and liquid droplets

  6. Sources of Partculate Matter 2.5

  7. Columbus/Phenix City PM2.5 Monitors

  8. ANNUAL PM2.5 STANDARD(3-year Average – microgram per cubic meter)2006 data through July for GA & through Sept for AL Standard

  9. Compliance History • US EPA has established national air quality standards for both 24-hour and annual PM levels • Areas that meet or exceed standards are designated as being in attainment • Areas not meeting the standards are called nonattainment areas

  10. Compliance History • June 2004: Columbus designated “attainment” for annual PM2.5 standard • 2005: Annual PM2.5 data for Columbus area exceeds annual standard • July 13, 2006: EPA and GA EPD officials meet with local officials to discuss high PM levels, preferred approach is to work with local stakeholders to reduce PM levels to acceptable levels • 2006: Annual PM2.5 data for Columbus area still exceeds annual standard

  11. Compliance History • September 2006: EPA proposed new, stricter revisions to the 24-hour PM2.5 standard, finalized in December 2006 • December 2007: States will make recommendations to EPA • December 2009: EPA will make final designations for nonattainment areas for PM2.5

  12. Air Quality Timeline – PM2.5 EPA Adopts new PM2.5 Standard Sept 2006 Attainment Deadline for Existing PM2.5 Standard 2009 Attainment Deadline for New PM2.5 Standard 2015-20 2006 2007 2008 2009 2010 2011 2012 2013 EPA Requests Plans to Bring Augusta & Columbus Back into Attainment Fall 2006 Non-attainment Designations for New PM2.5 Standards Dec 2009 New PM2.5 SIPs Due to EPAApril 2013

  13. Compliance History • We have an opportunity to take actions to reduce PM2.5 and prevent being designated as a nonattainment area • Staff is working directly with EPA, GEPD, ADEM, and others to develop a workable plan of action

  14. Impacts: Why is this Important? Health Effects: • Fine particulate matter (PM2.5) poses a greater risk to human health than coarse particulates because it more easily enters the lungs • Increased health risks: PM2.5 is known to aggravate heart and lung diseases, and is associated with heart attacks, chronic bronchitis, and asthma

  15. Impacts: Why is this Important? Economic Disadvantages: • Areas designated as nonattainment are subject to general and transportation conformity requirements for at least 20 years • Subject to more restrictive requirements for new construction or modification of major air pollution sources

  16. Local Impact on Transportation Conformity • Proposed highway projects must fit within SIP’s emission budget and not delay attainment of air quality standards – or risk losing federal funding • Could freeze federal highway funding • More direct Federal input into local planning projects • New sources of air pollution must meet stricter permitting requirements

  17. Local Impact on Transportation Conformity • Increased coordination with MPO • Less flexibility in revising project schedules • SPLOST projects must be reviewed by interagency partners • Long-Range Transportation Plan (LRTP) • LRTP and TIP amendments must be consistent with air quality requirements • Planning assumptions & projects now reviewed by Federal and State partners

  18. Transportation Conformity • Conformity Lapse = no capacity increasing transportation projects • Maintenance designation = 20 years of conformity process

  19. Ongoing Efforts • EPA’s preferred approach is to work with states and local stakeholders to develop a strategy for attainment • CCG Planning Department and C-PCMPO have met with governmental agencies to develop strategy • U.S. Environmental Protection Agency • Georgia Environmental Protection Division • Alabama Department of Environmental Protection • Federal Highway Administration • Alabama Department of Transportation • Georgia Department of Transportation • Clean Air Campaign • Fort Benning

  20. Ongoing Efforts • Implementing measures will take a cooperative effort among stakeholders; public awareness and outreach will be key elements • Success requires a bi-state effort that transcends geopolitical boundaries

  21. Where Do We Go from Here? • Assemble a regional air quality task force committee • Meeting tentatively set for September, 2007 • Form smaller subcommittees to address specific tasks, such as (but not limited to): • Outreach: public awareness and education • School programs • Telework and other traffic demand reduction programs • Open burning • Diesel emission reductions • From these meetings, a regional plan of action to be formed
