USEPA 2011-01-07 presentation

  1. 1. Regional Haze Rule and EPA’s Regulatory Responsibility for Navajo BART FIPs Colleen McKaughan Associate Director, Air Division U.s. Environmental Protection Agency Region 9 January 7, 2011
  2. 2. Topics <ul><li>Background on Regional Haze Rule and BART </li></ul><ul><li>EPA’s Regulatory Responsibility under the Regional Haze Rule </li></ul><ul><li>Other Pending EPA Regulations </li></ul><ul><li>EPA’s Limited Role in the Facilitated Process </li></ul>
  3. 3. Background on RH Rule <ul><li>The Regional Haze Rule was promulgated in July 1999 and became effective in 2005 and established a national goal for visibility in 156 Class I areas across the country </li></ul><ul><li>Class I areas are national parks and wilderness areas (i.e., Grand Canyon) </li></ul><ul><li>Goal is to achieve natural background levels by 2064 (i.e., no manmade visibility impairment) </li></ul>
  4. 4. EPA’s Regulatory Responsibility <ul><li>The Regional Haze Rule required states, but not tribes, to submit plans by Dec. 17, 2007 </li></ul><ul><li>Under the Tribal Authority Rule, EPA promulgates Federal Implementation Plans (FIPs) in tribal jurisdictional areas as necessary to protect air quality </li></ul>
  5. 5. Pollutants of Concern <ul><li>The visibility-impairing pollutants are: sulfur dioxide, nitrogen oxides, and particulate matter </li></ul><ul><li>EPA has already promulgated FIPs that made SO2 emission limits negotiated by the utility, Navajo Nation and NGOs federally enforceable for both NGS and Four Corners </li></ul><ul><li>As a result, the main pollutants of concern for visibility purposes are now nitrogen oxides and particulate matter </li></ul>
  6. 6. Ancillary Benefits <ul><li>Beyond improving visibility, additional controls of nitrogen oxides and particulate may have ancillary environmental and health benefits </li></ul>
  7. 7. The Navajo Power Plants <ul><li>NGS and Four Corners are two of the largest pollution sources in the U.S. </li></ul><ul><li>Visibility impairing pollution from Four Corners impacts 16 Class I areas </li></ul><ul><li>Navajo Generating Station impacts 11 Class I areas, including the Grand Canyon </li></ul>
  8. 8. Background on BART <ul><li>The Best Available Retrofit Technology (BART) provisions of the Regional Haze Rule require reductions in the emissions of air pollutants that impact visibility </li></ul><ul><li>This is typically accomplished by adding additional pollution control equipment to existing facilities, although there are other options </li></ul><ul><li>The only two BART-eligible sources on the Navajo Nation are NGS and Four Corners </li></ul>
  9. 9. BART Analysis <ul><li>The BART analysis determines the appropriate level of emissions controls for BART-eligible sources </li></ul><ul><li>A BART analysis requires consideration of the following five factors: </li></ul><ul><ul><li>Costs of compliance (i.e. cost effectiveness) </li></ul></ul><ul><ul><li>The energy and non-air quality environmental impacts of compliance </li></ul></ul><ul><ul><li>Any pollution control equipment in use at the source </li></ul></ul><ul><ul><li>The remaining useful life of the source </li></ul></ul><ul><ul><li>The degree of improvement in visibility (i.e. visibility benefits) </li></ul></ul>
  10. 10. Consultation <ul><li>EPA is required to consult with the Federal Land Managers in advance of proposed BART hearings </li></ul><ul><li>EPA has consultation obligation with all tribes who are impacted by our final rulemaking </li></ul><ul><li>Consultation can take different forms depending on the tribes’ preferences </li></ul>
  11. 11. Current Status of Rulemaking on NGS <ul><li>EPA is working on a proposal and intends to propose in early Summer. </li></ul><ul><li>For EPA to consider input from this facilitation in our proposed rulemaking, this group must provide its recommendations by end of March 2011. </li></ul>
  12. 12. Pending EPA Regulations Impacting Power Plants <ul><li>Mercury Maximum Achievable Control Technology – March 2011 proposal </li></ul><ul><li>Greenhouse Gases Source Performance Standards for Power Plants and Refineries - July 2011 proposal </li></ul><ul><li>Coal Combustion Residue (Fly Ash) Handling Regulations – proposed June 2010 </li></ul>
  13. 13. EPA’s Role in this Process <ul><li>To maintain regulatory neutrality EPA will not be participating in these discussions although we will be available to answer questions and provide information. </li></ul>
  14. 14. Contact Information and Website links <ul><li>Colleen McKaughan: </li></ul><ul><ul><li>520-498-0118 </li></ul></ul><ul><ul><li>[email_address] </li></ul></ul><ul><li> </li></ul>
