Memo:	Emission Reductions, Costs, Benefits and Economic Impacts Associated with Building Blocks 1 and 2
1 	Introduction
This memo provides estimates of the costs, energy impacts, and the monetized climate benefits and air pollution health co-benefits associated with emission reductions for two illustrative compliance scenarios associated with building blocks 1 and 2 only. It also includes estimates of the labor impacts on the regulated sector. The methods applied to generate these estimates are described in detail in Chapter 3, 4, and 6 of the Regulatory Impact Analysis (RIA). For brevity, this memo just reports the results of these analyses.
EPA used the Integrated Planning Model (IPM), developed by ICF International, to conduct this analysis. It provides forecasts of least cost capacity expansion, electricity dispatch, and emission control strategies while meeting energy demand and environmental, transmission, dispatch, and reliability constraints.
     This analysis also evaluates the climate benefits associated with emission reductions of CO2 and the air pollution health co-benefits associated with reduced emissions of SO2, NOx, and PM2.5, which would lead to lower ambient concentrations of PM2.5 and ozone. Unlike the analysis of health co-benefits in Chapter 4 of the RIA, estimates of emissions reductions of directly emitted particles available are not available for this analysis. Similar to Chapter 4 of the RIA, unquantified co-benefits include exposure to several HAPs (including mercury and hydrogen chloride), carbon monoxide, SO2, and NO2, as well as ecosystem effects and visibility impairment. 
2	State Goals for Building Blocks 1 and 2
This analysis includes state-specific rate-based goals that reflect a two-building block approach. It is also based upon the same modeling framework, assumptions and calculations as presented in the RIA. The two-blocks incorporated in the following state goals include efficiency improvements at existing coal steam electric generating units (EGUs) and use of lower emitting power sources (increased utilization of existing NGCCs) and are identical to the proposed levels, included for purposes of establishing state-specific goals, associated with Option 1 (6% efficiency improvement and no more than 70% redispatch).

5	Estimated Human Health Co-Benefits
Tables 22 through 24 provide the emission reductions estimated to occur in three analysis years (2020, 2025, and 2030) for two illustrative compliance scenarios (i.e., state and regional) by region (i.e., East, West, and California). Tables 25 through 27 report the health co-benefits estimated in three analysis years (2020, 2025, and 2030) for the two illustrative compliance scenarios (i.e., state and regional) evaluated.

* All estimates are rounded to two significant figures so numbers may not sum down columns. The estimated monetized co-benefits do not include climate benefits or reduced health effects from direct exposure to NO2, SO2, ecosystem effects, or visibility impairment. All fine particles are assumed to have equivalent health effects, but the benefit-per-ton estimates vary depending on the location and magnitude of their impact on PM2.5 levels, which drive population exposure. The monetized co-benefits incorporate the conversion from precursor emissions to ambient fine particles and ozone. Co-benefits for PM2.5 precursors are based on regional benefit-per-ton estimates. Co-benefits for ozone are based on ozone season NOx emissions. Ozone co-benefits occur in analysis year, so they are the same for all discount rates. Confidence intervals are unavailable for this analysis because of the benefit-per-ton methodology. In general, the 95[th] percentile confidence interval for monetized PM2.5 benefits ranges from approximately -90 percent to +180 percent of the central estimates based on Krewski et al. (2009) and Lepeule et al. (2012).

*All estimates are rounded to two significant figures. Climate benefits are based on reductions in CO2 emissions. Co-benefits are based on regional benefit-per-ton estimates. Co-benefits for ozone are based on ozone season NOx emissions. Ozone co-benefits occur in analysis year, so they are the same for all discount rates. The health co-benefits reflect the sum of the PM2.5 and ozone co-benefits and reflect the range based on adult mortality functions (e.g., from Krewski et al. (2009) with Bell et al. (2004) to Lepeule et al. (2012) with Levy et al. (2005)). The monetized health co-benefits do not include reduced health effects from direct exposure to NO2, SO2, and HAP; ecosystem effects; or visibility impairment.

*All estimates are rounded to two significant figures. Climate benefits are based on reductions in CO2 emissions. Co-benefits are based on regional benefit-per-ton estimates. Co-benefits for ozone are based on ozone season NOx emissions. Ozone co-benefits occur in analysis year, so they are the same for all discount rates. The health co-benefits reflect the sum of the PM2.5 and ozone co-benefits and reflect the range based on adult mortality functions (e.g., from Krewski et al. (2009) with Bell et al. (2004) to Lepeule et al. (2012) with Levy et al. (2005)). It is important to note that the monetized health co-benefits do not include reduced health effects from direct exposure to NO2, SO2, and HAP; ecosystem effects; or visibility impairment.

[a] All estimates are for 2020 and are rounded to two significant figures, so figures may not sum.
[b] The climate benefit estimates in this summary table reflect global impacts from CO2 emission changes and do not account for changes in non-CO2 GHG emissions. Also, different discount rates are applied to SCC than to the other estimates because CO2 emissions are long-lived and subsequent damages occur over many years. The SCC estimates are year-specific and increase over time. 
[c] The air pollution health co-benefits reflect reduced exposure to PM2.5 and ozone associated with emission reductions of directly emitted PM2.5, SO2 and NOX. The range reflects the use of concentration-response functions from different epidemiology studies. The reduction in premature fatalities each year accounts for over 90 percent of total monetized co-benefits from PM2.5 and ozone. These models assume that all fine particles, regardless of their chemical composition, are equally potent in causing premature mortality because the scientific evidence is not yet sufficient to allow differentiation of effect estimates by particle type. 
[d] Total costs are approximated by the illustrative compliance costs estimated using the Integrated Planning Model and a discount rate of approximately 5%. This estimate includes monitoring, recordkeeping, and reporting costs and demand side energy efficiency program and participant costs.
[e] The estimates of net benefits in this summary table are calculated using the global SCC at a 3 percent discount rate (model average). Tables 10-12 in this memo  present  combined climate and health estimates based on additional discount rates.

[a] Job-year estimates are derived from IPM investment and O&M cost estimates, as well as IPM fuel use estimates (tons coals or MMBtu gas)
[b]All job-year estimates on this are Full Time Equivalent (FTE) jobs. Job estimates in the Demand-Side energy efficiency section (below) include both full time and part time jobs
*Construction-related job-year changes are one-time impacts, occurring during each year of the 2 to 4 year period during which construction and HRI installation activities occur. Figures in table are average job-years during each of the years in each range. Negative job-year estimates when additional generating capacity must be built in the base case, but is avoided in the Guideline implementation scenarios due to HRI or Demand-side energy efficiency programs. 
**Recurring Changes are job-years associated with annual recurring jobs including operating and maintenance activities and fuel extraction jobs. Newly built generating capacity creates a recurring stream of positive job-years, while retiring generating capacity, as well as avoided new built capacity, create a stream of negative job-years. In addition, there are recurring jobs prior to 2020 to fuel and operate new generating capacity brought online before 2020; the recurring jobs prior to 2020 are not estimated.
