Goals of Presentation
• Explain MANE-VU’s approach to establishing reasonable progress goals and defining a long term strategy for meeting those goals
• Review the anticipated visibility impacts and cost & benefit analyses of the long term strategy
• Describe specific elements of long-term strategy

Principles• June 2007 Board Meeting Resolution by MANE-VU Class
I States on Principles for Implementing the Regional Haze Rule includes:– Establishing Reasonable Progress Goals reflecting the 4-factor
analysis to determine measures to be implemented by contributing states
– Achieving as much or more visibility improvement as the Uniform Rate of Progress
– Providing flexibility to states in in meeting the requested emission reductions
– Calling upon EPA and FLMs to identify/act on inconsistencies– Other key provisions reflecting the MANE-VU approach
• MANE-VU States are not asking others to do more than we are willing to do ourselves

MANE-VU Statements – Our “Ask”for Improved Visibility from States
Other Regions:• BART• Focused EGU Strategy
within CAIR• 28% reduction in non-
EGU SO2 emissions• Continued evaluation of
other measures, including from all coal-burning facilities, and others
MANE-VU:• BART• Focused EGU Strategy
within CAIR • Low sulfur fuel oil
strategy• Continued evaluation of
other measures, including Energy Efficiency, Clean Fuels and others

4-Factor Analysis:Requirements
• 4 factors to consider to determine reasonable measures:– Costs of compliance– Time necessary for compliance– Remaining useful life of any existing source
subject to such requirements – Energy and non-air quality environmental
impacts of compliance

Benefits/Cost Analysis
• Weighs costs of imposing a regulatory program against monetized benefits of adoption
• Health and environmental benefits of air quality regulation has not traditionally been easy to monetize
• New tools developed by EPA help to identify these benefits of control programs

What did we do?• Benefits analysis of four potential regional
haze control measures in 2018• Reference Scenario: On the Books/On
the Way (OTB/OTW) • Control Scenarios:
– “S-1” and “S-2” fuel strategies– BART (anticipated reductions)– “167 Stack” EGU strategy
• Estimated benefits with BenMAP

Opportunities for SO2Emission Reduction
• EGUs @ $1,400/ton (IPM for >CAIR)• Industrial Boilers @ $150 - $10,000/ton
– Oil – 19,000 tons– Coal – 40,500 tons
• Fuel Oil @ $500 - $5000/ton– Distillate – 110,000 – 140,000 tons– Residual – 22,000 tons
• BART – 37,000 tons14

Description of Strategies
• S1-Low Sulfur Fuel (500ppm)• S2-Low Sulfur Fuel (15ppm)• BART- 2018 projections for 14 facilities
expected to be controlled solely due to BART.
• 167 Stack Strategy – 90% control at “top impactors” relative to VISTAS IPM 2.1.9

1. Low Sulfur Oil Strategies• Distillate (#2)
– 500 ppm by 2012, 2014 (S-1)
– 15 ppm by 2016, 2018 (S-2)
• #4 Residual (S-1 & S-2)– 0.25% to 0.5% by
2012, 2018• #6 Residual (S-1 & S-2)
– 0.3 to 0.5% by 2012, 2018
• Cost: Fuel costs may increase, but lowermaintenance costs willpartially offset
• Compliance Time: Phase-in allows time forcompliance
• Useful Life: Lower Sulfurshould extend life ofboilers
• Energy & OtherEnvironmental Impacts: Higher combustionefficiency

3. “167 Stack” EGU Strategy
• Control strategy focused on reducing SO2emissions from power plants.
• Emissions from power plants continue to dominate the SO2 emissions inventory and are responsible for over half the mass and approximately 70-80 percent of the Haze
• MANE-VU is asking for 90% control at 167 “top impactors” relative to 2002

In summary
• MANE-VU Class I areas are preparing to establish reasonable progress goals based on an analysis of the impacts of reasonable strategies
• The strategies include additional SO2 controls both within and outside MANE-VU
• States will have up to 2018 to adopt and implement additional strategies
