Roadmap • Integrated Assessment Approach • 1990 CAAA • NOx SIP Call • Multi-pollutant legislation − Efficient Emission Fees for SO2, NOx − Proposal Targets, Benefits − Errors and Uncertainties in Benefit Estimates − Guidelines for Hg − Architecture for Carbon Benefits of Reduced Air Pollution

Integrated Assessment: Meaning and Method • Integration of full­form models with “internal” validity • Emphasis on “external” integrity • Account for correlated uncertainty • Include assessment • Value of additional information NYSERDA played a path­breaking role in the application of integrated assessment in the early 1990s with co­sponsorship of the ESEERCO externality study.

Spatial Effects of Trading • In 1993, the NY AG sued EPA to restrict allowance sales. • NY Assembly, later Senate, voted to constrain trades. • 1998 agreement with Long Island Lighting Company (LILCO). • 1998 Senator D’Amato likened long-range transport of acid rain to “airborne terrorism.” • 2000 Governor Pataki signed into law legislation to monitor and control sale of SO 2 allowances. • 2003 Appeals court strikes down NY law.

The Second Grand Experiment: NOx SIP Call • NO x emissions contribute to multiple problems: – ozone, particulates, nitrogen deposition, visibility • Nonattainment of ozone standard provides regulatory handle for EPA NO x SIP Call • Policy aimed at ozone, a seasonal problem • But, other NO x ­related effects are realized throughout the year • Costs of NO x control are largely fixed and capital costs. Annual vs. Seasonal NOx Controls” ( JAWMA 01; Land 03) Benefits of Reduced Air Pollution

Question: What is the most cost-effective way to achieve NO x reductions given full set of NO x related problems? Three NO x reduction scenarios: – Summer cap in 19 state SIP Call region – Annual cap in the same SIP Call region – National Annual cap Benefits of Reduced Air Pollution

Major Uncertainties • Market Structure • Epidemiology / Mortality • Valuation / Mortality Benefits of Reduced Air Pollution

RFF “Haiku” Electricity Model • Intra­regional market modeling – Market equilibrium in 13 regions – Demand: 3 customer classes, 4 time periods, 3 seasons – Supply constructed using model plants • Defined by technology, fuel type, vintage • Investment and retirement • Emission compliance • Fuel market prices adjust • Inter­regional power trading – Equilibrates regional prices, transmission constraints Benefits of Reduced Air Pollution

Main Findings Favor Annual NOx Controls • Under all scenarios SIP Annual policy yields greater net benefits than current policy; Ohio Valley included. • National annual policy is slightly less cost­effective than current under preferred assumptions …but it is more cost­effective under majority of scenarios. • SIP region always realizes greatest net benefits under National Annual policy. • Omitted benefits do not change ranking for SIP Annual Benefits of Reduced Air Pollution

State Actions in SIP Call region Connecticut, Massachusetts, New Hampshire, North Carolina and New Yo rk have moved to annual contro ls on NO x and SO 2 . State actions amplify the challenges to resource planning for electricity generators. Benefits of Reduced Air Pollution
