  1. Draft Regional Haze SIP SIP Steering Committee January 13, 2011

  2. Regional Haze Requirements • 1977 Clean Air Act Amendments: Congress hereby declares as a national goal the prevention of any future, and the remedying of any existing, impairment of visibility in mandatory Class I Federal areas which impairment results from man-made air pollution. • Goal: To achieve natural background conditions in all Class I areas by 2064

  3. Core Requirements of Regional Haze Rule • Calculation of Baseline and Natural Visibility Conditions • Reasonable Progress Goals • Best Available Retrofit Technolgoy (BART) • Long-term Strategy (control measures needed to achieve reasonable progress goals)

  4. Class I Areas Impacted by Emissions from Massachusetts Sources

  5. Modeled 2002 Contributions to Sulfate by State at Acadia National Park MA

  6. MANE-VU “Ask” • Timely Implementation of Best Available Retrofit Technology (BART) • Low Sulfur Fuel Oil Strategy • 90% Reduction in SO2 Emissions from each of the top 167 stacks at 100 EGUs identified by MANE-VU as contributing to haze • Continued evaluation of other control measures

  7. BART • Applies to NOx, SO2, and PM2.5 Emissions • 26 major point source categories • 250 tons/year of any haze-forming pollutant • Commenced operation between Aug. 7, 1962 – Aug. 7, 1977

  8. MA BART-Eligible Sources

  9. Transport Rule as Alternative to Bart (SO2)

  10. Transport Rule as Alternative to Bart (NOx)

  11. Low-Sulfur Fuel Oil Strategy

  12. Average Change in 24-hr PM2.5due to Low-Sulfur Fuel Strategies (µg/m3)

  13. “167 Stacks” 90% Reduction met by Transport Rule

  14. Average Change in 24-hr PM2.5 due to 90% Reduction in SO2 Emissions from 167 Stacks (µg/m3)

  15. Other Considerations / Control Measures • Construction Activities • Agricultural and Forestry Smoke Management • MassDEP including Outdoor Hydronic Heater (Outdoor Wood-fired Boiler) regulation in SIP

  16. Draft Regional Haze SIP Process • Preliminary draft SIP reviewed by Federal Land Managers and EPA in 2008/09 • Draft SIP hearings 2/10/11 and 2/11/11; comments by 2/21/11 • Submit final SIP to EPA for approval in Spring; propose low sulfur fuel regulations • Full SIP approval by EPA likely contingent on finalization of Transport Rule, low sulfur fuel regulations, amended permits
