  4. Regional Haze Rule (RHR)40 CFR Subpart §51.300-51.309 The Clean Air Act requires (Best Available Retrofit Technology) BART review when any source that “emits any air pollutant which may reasonably be anticipated to cause or contribute to any impairment of visibility” in any 156 Federal Class I area There are sixteen (16) and eleven (11) Class I area within 300 km (186 mi) radius of the Four Corners Power Plant and Navajo Generating Station Predicted visibility impact with baseline emissions exceeds 0.5 delta- deciview

  5. Regional Haze Visibility Impact Worst 24-hr avg visibility Best 24-hr avg visibility

  6. Timeline For Proposed Activities 53 Years 2064 2011 “Goal is to achieve natural background levels by 2064 (i.e., no manmade visibility impairment)” Every 10 years beginning in 2018 the previous SIP/FIP must be updated to account for current visibility and progress made toward the 2064 goal

  7. Federal Class 1 Areas Within NGS & FCPP

  8. BART Five Factor Analysis40 CFR § 51 Appendix Y

  9. Four Corners Power Plant Pre- BART Operation • APS = 100% unit 1,2,3, Unit 4,5 : SCE 48 %, APS 15%, PNM 13%, SRP 10%, EPE 7%, TEP 7% Unit 4 &5 750MW per unit Unit 3 280MW Unit 1 &2 185MW per unit

  10. Four Corners Power Plant Better Than BART Proposal • APS = 100% unit 1,2,3, Unit 4,5 : SCE 48 %, APS 48+15=63%, PNM 13%, SRP 10%, EPE 7%, TEP 7% Unit 4 &5 750MW per unit Unit 3 280MW Unit 1 &2 185MW per unit SCR

  11. Navajo Generating Station (NGS) BART Decision Pending !!!! U.S.BOR =24.3%, SRP = 21.7%, LADWP = 21.2% , APS = 14%, NPC = 11.3%, TEP = 7.5% Unit 1, 2 and 3 = 750 MW each

  12. NGS Studies

  13. San Juan Generating Station BART-Nation Position • EPA R6 BART FIP • NMED Failed to Submit RH SIP • SCR on all Four Units • BART FIP will have No Tribal Implications • No Economic Impacts Analyzed • Compliance timeline increased from 3 to 5 years • NMED RH SIP • SNCR on all Four Units • Meet Presumptive BART Limits • Visibility Improvement aligns with SIP • Economic Impact to NM ratepayers analyzed • SCR cost too high compared to SNCR • Navajo Nation Position • EPA Consider NM RH SIP • EPA failed to conduct full five factor analysis • EPA analysis of no Tribal implications is not supported • Economic Impacts, Regional Cumulative Benefits

  14. Degree of Visibility Improvement BART guidelines recommend use of the CALPUFF IMPROVE monitoring network Western Regional Air Partnership (WRAP) 1 ppb IWAQM default value for ammonia background HCL and HF Emission Factors USEPA approval modeling protocol
