Early Action Compacts for 8-Hour Ozone Nonattainment Designation Implementation

This document outlines the Early Action Compacts aimed at addressing 8-hour ozone nonattainment designations in EPA Region 4, presented by Karen Borel on March 25, 2003. It details implementation guidance, including the requirements for State Implementation Plans (SIPs), emissions inventories, and control measures necessary for attainment. Specific milestones, timelines, and compact requirements for several states are discussed, highlighting the collaborative approach between the EPA and local governments to enhance air quality and meet national standards by 2007, with a focus on public engagement and planning efforts.

  1. Early Action Compacts Presented by Karen Borel EPA Region 4 March 25, 2003

  2. Implications of 8-Hour Ozone Nonattainment Designation • Implementation Guidance will provide guidance on boundaries and designations • Areas will be subject to nonattainment area requirements • New Source Review • Conformity • Will apply one year after designation • Requires that area transportation plan show “conformity” with SIP motor vehicle emissions budget • Development & Submittal of State Implementation Plan • Schedule for SIP Submittal given at designation • Attainment demonstration, control measures, modeling • NOx SIP Call, Tier 2 and Low Sulfur Gasoline controls expected to aid many areas in attaining

  3. Boundary Guidance (March 28, 2000) • Design Value for the Area • Period of Time Represented by the Design Value • Monitoring Site Location and Identification Number • Population • Traffic and Commuting Patterns • Commercial Development • Growth • Prevailing Meteorology • Nearby Sources • Other Justification Factors

  4. 8-Hour Ozone NAAQS - Schedule for Implementation • 2002-2003 - Propose and finalize rulemaking on the implementation approach • April 2003 - State/Tribes to update recommended designations • April 2004 - EPA will promulgate air quality designations • State implementation plans (SIPs) - likely due in 2007-2008 time frame, with attainment dates ranging from 2007 to 2019 or longer.

  5. Early Action Compact • On June 19, 2002, EPA Region 6 endorsed Texas’ Protocol for an Early Action Compact • Protocol deals with attainment of the 8-hr National Ambient Air Quality Standards (NAAQS) for ozone • Calls for “early” SIPs and associated controls coupled with a deferral of the effective date of future EPA ozone nonattainment (NA) designations.

  6. Compact Requirements - Milestones and Reporting …. • Completion of emissions inventories and modeling • Adoption of control strategies that demonstrate attainment • Completion and adoption of the early action SIP revision • Attainment not later than December 31, 2007 • Post-attainment demonstration and plan updates

  7. Who Submitted EACs in Region 4? • North Carolina • 4 Areas – includes 20 Counties and 19 Cities • Mountain area (Western NC, including Asheville; Unifour (Hickory area); Triad (Greensboro area); and Fayetteville • South Carolina • 10 Areas – includes 45 of 46 counties in SC, and 2 Counties in GA • Greenville; Charlotte, Florence, Charleston, Augusta-Aiken, Columbia and others • Tennessee • 8 areas – includes 30 Counties and 7 Cities • Chattanooga, Knoxville, Johnson City/Kingsport, Memphis, Nashville and others

  8. Timeline • December 31, 2002 - Compact signed by all parties in MSA (local officials, state air quality agency, and EPA Region) • June 16, 2003 - Submit list of local control measures being considered • March 31, 2004 - Local plan submitted to the state • April 2004 – EPA designates “Compact Areas” as nonattainment, but defers effective date for these areas

  9. Timeline (continued) • December 31, 2004 - State adopts control measures into SIP & submits to EPA for approval • 2005 – Areas implement control measures • June 30, 2006 - Progress assessment and report to EPA • December 2007 – Areas attain 8-hr ozone NAAQS

  10. June 2003 Milestone Requirements • List of Possible Control Measures – due June 16, 2003 • Progress Report – June 2003

  11. Components of List • Sufficient list to achieve reductions needed to attain by 2007 • Measures that are reasonable and can be implemented in specific area • Description of measure and analysis of its implementation • Estimate of emissions reductions, if known • Documentation of stakeholder process

  12. Components of Progress Report • Document progress in developing stakeholder process • Describe public outreach activities • Update on modeling/technical planning activities • Progress on evaluating and selecting emission reduction measures (can use June 16 list)
