X^ED \ ^ PROf^ Technical Support Document Estimating the Benefit per Ton of Reducing PM2.5 Precursors from 17 Sectors U.S. Environmental Protection Agency Office of Air and Radiation Office of Air Quality Planning and Standards Research Triangle Park, NC 27711 l February 2018 ------- CONTACT INFORMATION This document has been prepared by staff from the Office of Air Quality Planning and Standards, U.S. Environmental Protection Agency. Questions related to this document should be addressed to Neal Fann or Elizabeth Chan, U.S. Environmental Protection Agency, Office of Air Quality Planning and Standards, Health and Environmental Impacts Division, Risk and Benefits Group, Research Triangle Park, North Carolina 27711 (email: fann.neal@epa.gov, chan.elizabeth@epa.gov). 2 ------- Background and Overview In 2013, the Agency published a Technical Support Document (TSD) (U.S. EPA 2013) describing an approach for estimating the average avoided human health impacts, and monetized benefits related to emissions of PM2.5 and PM2.5 precursors including NOxand SChfrom 17 sectors using the results of source apportionment photochemical modeling. The Agency periodically updates the demographic and economic input parameters used to quantify the incidence and dollar value of air pollution-related effects. In 2017, EPA released a new version of its environmental Benefits Mapping and Analysis Program— Community Edition (BenMAP-CE) tool that incorporated new demographic and economic parameters; these are summarized below and described in greater detail in a memorandum available here. Using this new version of BenMAP-CE, we re-calculated the PM2.5 benefit per-ton values (BPT). When calculating these new BPT values, we used the same emission and air quality input parameters as was used in the 2013 TSD (U.S. EPA 2013) and a published manuscript (Fann et al. 2012). Below we describe: our approach to calculating a BPT value; the new demographic and economic datasets we incorporated into BenMAP-CE; and, the limitations and uncertainties associated with application of these estimates. Finally, we summarize the benefit per ton estimates for each of the 17 emission sectors. Readers interested in learning more about the emissions and air quality input parameters may refer to a separate TSD detailing the modeling or the two published manuscripts that detail the photochemical modeling simulations (Fann et al. 2013, 2012; U.S. EPA 2011). Approach to Calculating Benefit Per-Ton Values The procedure for calculating benefit per ton coefficients follows three steps, shown graphically in Figure 1: 1. Using source apportionment photochemical modeling, predict annual average ambient concentrations of primary PM2.5, nitrate and sulfate attributable to each of 17 emission sectors across the Continental U.S.; see below for a summary of the sectors modeled. 2. For each sector, estimate the health impacts, and the economic value of these impacts, associated with the attributable ambient concentrations of primary PM2.5, sulfate and nitrate PM2.5 using the environmental Benefits Mapping and Analysis Program-Community Edition (BenMAP vl.3.71).1 1 In this stage we estimate the PM2.s-related impacts associated with changes in directly emitted PM2.5, nitrate 4 ------- 3, For each sector, divide the PM2.5-related health impacts attributable to each type of PM2.5, and the monetary value of these impacts, by the level of associated precursor emissions. That is, primary PM2.5 benefits are divided by direct PM2.5 emissions, sulfate benefits are divided by SO2 emissions, and nitrate benefits are divided by NOxemissions. > & Benefits and avoided impacts ; -— = Benefit ton Scenario emissions PM2 5 air quality foi a Human health impacts Benefit-per-ton calculation given sector Figure 1. Conceptual overview of the steps for calculating benefit per-ton estimates Sectors Analyzed The example above depicts the total PM2.5 contribution from the pulp and paper sector, though we repeat this process for each of the 17 sectors, which include: 1. Locomotives and marine vessels2 2. Area sources 3. Cement kilns 4. Coke ovens 5. Electric arc furnaces 6. Electricity generating units 7. Ferroalloy facilities 8. Industrial point sources 9. Integrated iron and steel facilities 10. Iron and steel facilities 11. Non-road mobile sources 12. Ocean-going vessels 13. On-road mobile sources 14. Pulp and paper facilities and sulfate separately, so that we may ultimately calculate the benefit per ton reduced of the corresponding PM2.5 precursor, or directly emitted PM2.5, in step 3. When estimating these impacts we apply effect coefficients that relate changes in total PiVh.s mass to the risk of adverse health outcomes; we do not apply effect coefficients that are differentiated by PM2.5 specie. 2 The prior version of this TSD specified this sector as "Air, Locomotive and Marine Vessels." The Agency subsequently learned that, due to an emissions processing error, this sector omits Aircraft emissions. 5 ------- 15. Refineries 16. Residential wood combustion 17. Taconite mines The "Area sources" and "Industrial point sources" categories are an agglomeration of emission sectors that were not otherwise specified elsewhere. When selecting a benefit per ton estimate for use with a sector not specifically modeled, it is necessary to determine which composite sector is the best match with respect to the source characteristics that would affect the level of benefits. These attributes include the proximity to receptor populations, the geographic distribution of sources, and the release parameters of the source (e.g., stack height). Readers interested in a full discussion of the air quality modeling performed to generate these benefit per ton estimates may consult "Air Quality Modeling Technical Support Document: Source Sector Assessments" (U.S. EPA 2011). Ambient PM2.5 concentrations attributable to each sector were projected from the 2005 baseline to 2016 to represent growth and the application of controls. The starting point for the projections was the 2005 v4.3 emissions platform (US EPA 2005). EGU emission estimates for 2016 are from the Integrated Planning Model (IPM). The 2016 projection included emission reductions related to the NOx State Implementation Plan Call (US EPA 1998), the Maximum Achievable Control Technology (MACT) Standards for Industrial Boilers (US EPA 2011d) and Reciprocating Internal Combustion Engines (US EPA 2010b), and the proposed Transport Rule affecting emissions from Electricity Generating Units (US EPA 2010c). Control and growth factors, including known plant shut-downs and economic growth in some sectors, were applied to a subset of the 2005 industrial point sources and area sources to create the 2016 projection. Other North American emissions are based on a 2006 Canadian inventory and 1999 Mexican inventory, which are not grown or controlled when used as part of future year baseline inventories (US EPA 2011b; US EPA 2011c). Global emissions are included in the modeling system through boundary condition inflow to the 36 km CAMx simulation. The initial and boundary conditions for the 36 km CAMx simulation are based on 3-hourly output from an annual 2005 GEOS-CHEM simulation (standard version 7-04-11). Table 1 summarizes the total precursor emissions attributable to each sector in 2016. Appendix B of this TSD includes plots of the PM2.5 levels attributed to each of these sectors for which we estimated benefit per-ton metrics. 6 ------- Table 1. 2016 emissions by sector (tons per year) Sector voc NOx PM2.5a SO2 NHs Aircraft, locomotives and marine vessels 43,547 1,342,849 35,604 9,087 940 Area sources 9,380,925 1,633,261 325,820 1,243,154 126,802 Cement kilns 3,059 130,536 1,106 48,737 679 Coke ovens 7,821 16,110 368 27,952 1,084 Electric arc furnaces 3,560 15,707 622 6,088 119 Electricity generating units 63,198 1,826,582 30,078 3,793,362 36,706 Ferroalloy facilities 150 3,412 201 4,580 510 Industrial point sources 1,259,745 1,263,276 67,614 877,620 140,948 Integrated iron and steel facilities 9,620 31,925 2,856 29,045 167 Iron and steel facilities 14,384 5,867 1,366 3,590 166 Non-road mobile sources 1,953,067 1,259,578 106,975 2,879 2,345 Ocean-going vessels 66,093 1,534,234 7,407 439,987 0 On-road mobile sources 2,357,108 4,239,971 118,986 26,786 82,094 Pulp and paper facilities 121,597 240,139 10,067 170,393 10,859 Refineries 111,391 118,206 7,379 132,337 3,556 Residential wood combustion 538,466 33,786 192,492 4,720 6,586 Taconite mines 606 41,350 884 8,823 4 a This value includes elemental and organic carbon, which were used for the benefit per ton calculations. 7 ------- The photochemical modeling used here also produced estimates of ozone levels attributable to each sector. However, the complex non-linear chemistry governing ozone formation prevented us from developing a complementary array of ozone benefit per ton values. This limitation notwithstanding, we anticipate that the ozone-related benefits associated with reducing emissions of NOxand VOC for many of these sectors could be substantial. While most VOCs emitted are oxidized to carbon dioxide (CO2) rather than to PM, a portion of VOC emission contributes to ambient PM2.5 levels as organic carbon aerosols (U.S. EPA 2009). Therefore, reducing VOC emissions would reduce the level of PM2.5 formed in the atmosphere, human exposure to PM2.5, and the incidence of PM2.5-related health effects. However, we have not quantified VOC benefit per ton estimates in this analysis. Uncertainties in both the origin and quantity of emissions contributing to secondary organic aerosol on regional scales limit the quality of regional scale modeling of secondary organic carbon. Modeling and monitoring the relative amount of organic particles that are formed through secondary processes, versus primarily emitted organic particles, is highly uncertain. While the relative contributions of different sources to regional sulfate and nitrate can be quantified with certainty, the contributions from different sources to secondary organic aerosol are less clear. Carbonaceous aerosol reflects a complex mixture of hundreds to thousands of organic carbon compounds, many of which have not been successfully quantified. Despite progress that has been made in understanding the origin, properties, and key formation processes of SOA, it remains the least understood component of PM2.5 (U.S. EPA 2004). Below we provide an expanded discussion of each of the latter two steps to the calculation—estimating health impacts and economic value of PM2.5 attributable to each sector and calculating the benefit per ton coefficients. The discussion of these topics is not intended to be exhaustive, and readers interested in learning more about our approach to performing an air pollution health impact and benefits analysis may consult the PM NAAQS RIA (US EPA 2012). Estimating the number of PM2.5-related health impacts attributable to each sector In this stage of the analysis we performed a Health Impact Assessment (HIA), which quantifies the changes in the incidence of adverse health impacts resulting from changes in human exposure to PM2.5 from each sector. HIAs are a well-established approach for estimating the retrospective or prospective change in adverse health impacts expected to result from population-level changes in exposure to pollutants (Hubbell et al. 2009b, 2009a). PC-based tools such as the environmental Benefits Mapping and Analysis Program (BenMAP) can systematize health impact analyses by applying a database of key input 8 ------- parameters, including health impact functions and population projections (US EPA). Analysts have applied the HIA approach to estimate human health impacts resulting from hypothetical changes in pollutant levels(Davidson et al. 2007; Hubbell et al. 2004; Tagaris et al. 2009). The HIA approach used in this analysis involves three basic steps: (1) utilizing CAMx-generated estimates of PM2.5 levels attributed to each sector; (2) determining the subsequent change in population-level exposure; (3) calculating health impacts by applying concentration-response relationships drawn from the epidemiological literature to this change in population exposure (Hubbell et al. 2004). This procedure is operationalized within BenMAP using a health impact function (Eq 1). We estimated the number of PM2.5-related total deaths and illnesses (y//) during each year / (i=2016, 2020, 2025, 2030) among populations in each 12km by 12km air quality model grid cell j (j=l,...,J where J is the total number of grids) as yij = Ea yija yija = mOija x[eP-cj-1) x Pi]aj Eq[l] where /? is the risk coefficient for all-cause mortality for adults in association with PM2.5 exposure, moija is the baseline all-cause mortality or morbidity rate for populations aged a in grid cell j in year / stratified in 10-year age bins, Cij is annual mean PM2.5 concentration in grid cell j, and Pi]a is the number of individuals aged a in grid cell j in year / stratified into 5-year age bins. Tools such as BenMAP can systematize the HIA calculation process, allowing users to draw upon a library of existing air quality monitoring data, population data and health impact functions. Figure 2 provides a simplified overview of this approach, using PM2.5-related premature mortality as an example, though the procedure is generally the same for other health endpoints. This sequence of steps is performed for each of the 17 sectors for each PM2.5 component (primary PM2.5, sulfate and nitrate). The PM2.5 health endpoints quantified and the health impact functions applied in this analysis are consistent with the PM NAAQS RIA (US EPA 2012). That RIA includes a detailed discussion of each of the data inputs, analytical assumptions and sources of uncertainty. In the interest of brevity, we do not repeat these here in detail. However, it is worth noting that we exclude the value of several important non-health endpoints, including recreational and residential visibility, climate-related impacts and ecological endpoints. Table 2 below summarizes the endpoints quantified in this benefit per ton TSD. 9 ------- Baseline Air Quality Post-Policy Scenario Air Quality Figure 2.

In the PM NAAQS RIA, these benefits were quantified in a sensitivity analysis, but not in the core analysis. 2 We assess these benefits qualitatively because we do not have sufficient confidenc e in available data or methods. 3 We assess these benefits qualitatively because current evidence is only suggestive of causality or there are other significant concerns over the strength of the association. 11 ------- Estimating the economic value of health impacts attributable to each sector After quantifying the number of adverse air pollution-attributable impacts, the next step is to estimate the economic value of these events. The appropriate economic value for a change in a health effect depends on whether the health effect is viewed ex ante (before the effect has occurred) or ex post (after the effect has occurred). Reductions in ambient concentrations of air pollution generally lower the risk of future adverse health effects by a small amount for a large population. The appropriate economic measure is therefore ex ante Willingness to Pay (WTP) for changes in risk. However, epidemiological studies generally provide estimates of the relative risks of a particular health effect avoided due to a reduction in air pollution. A convenient way to use this data in a consistent framework is to convert probabilities to units of avoided statistical incidences. This measure is calculated by dividing individual WTP for a risk reduction by the related observed change in risk. For example, suppose a measure is able to reduce the risk of premature mortality from 2 in 10,000 to 1 in 10,000 (a reduction of 1 in 10,000). If individual WTP for this risk reduction is $100, then the WTP for an avoided statistical premature mortality amounts to $1 million ($100/0.0001 change in risk). Using this approach, the size of the affected population is automatically taken into account by the number of incidences predicted by epidemiological studies applied to the relevant population. The same type of calculation can produce values for statistical incidences of other health endpoints. For some health effects, such as hospital admissions, WTP estimates are generally not available. In these cases, we use the cost of treating or mitigating the effect as a primary estimate. For example, for the valuation of hospital admissions we use the avoided medical costs as an estimate of the value of avoiding the health effects causing the admission. These cost of illness (COI) estimates generally (although not in every case) understate the true value of reductions in risk of a health effect. They tend to reflect the direct expenditures related to treatment but not the value of avoided pain and suffering from the health effect. Avoided premature deaths account for 98% of monetized PM-related benefits. The economics literature concerning the appropriate method for valuing reductions in premature mortality risk is still developing. The adoption of a value for the projected reduction in the risk of premature mortality is the subject of continuing discussion within the economics and public policy analysis community. Following the advice of the SAB's Environmental Economics Advisory Committee (SAB-EEAC), the EPA currently uses the value of statistical life (VSL) approach in calculating estimates of mortality benefits, because we believe this calculation provides the most reasonable single estimate of an individual's willingness to trade off money for reductions in mortality risk (U.S. EPA Science Advisory Board 2000). The VSL approach is a summary measure for the value of small changes in mortality risk experienced by a large number of people. 10 ------- EPA continues work to update its guidance on valuing mortality risk reductions, and the Agency consulted several times with the SAB-EEAC on the issue. Until updated guidance is available, the Agency determined that a single, peer-reviewed estimate applied consistently best reflects the SAB-EEAC advice it has received. Therefore, EPA has decided to apply the VSL that was vetted and endorsed by the SAB in the Guidelines for Preparing Economic Analyses (U.S. EPA 2000) while the Agency continues its efforts to update its guidance on this issue.2 This approach calculates a mean value across VSL estimates derived from 26 labor market and contingent valuation studies published between 1974 and 1991. The mean VSL across these studies is $6.3 million (2000$).3 We then adjust this VSL to account for the currency year used for the analysis and to account for income growth from 1990 to the analysis year. Table 3 shows the adjusted VSL estimates for currency years 2000-2015 for the income growth years used in the source apportionment benefit per ton calculations. Table 3. Value of a Statistical Life Estimate Adjusted for Currency and Income Growth Years VSL with Income Growth to: Currency Year Base VSL 2016 2020 2026 2000 $6.3 $7.3 $7.4 $7.5 2001 $6.5 $7.5 $7.6 $7.7 2002 $6.6 $7.6 $7.7 $7.9 2003 $6.7 $7.8 $7.9 $8.0 2004 $6.9 $8.0 $8.1 $8.3 2005 $7.1 $8.2 $8.4 $8.5 2006 $7.4 $8.5 $8.6 $8.8 2007 $7.6 $8.7 $8.9 $9.1 2008 $7.9 $9.1 $9.2 $9.4 2009 $7.8 $9.0 $9.2 $9.4 2010 $8.0 $9.2 $9.3 $9.5 2011 $8.2 $9.5 $9.6 $9.8 2012 $8.4 $9.7 $9.8 $10.0 2013 $8.5 $9.8 $10.0 $10.2 2014 $8.7 $10.0 $10.1 $10.3 2015 $8.7 $10.0 $10.2 $10.4 2 In the updated Guidelines for Preparing Economic Analyses (US EPA 2010), EPA retained the VSL endorsed by the SAB with the understanding that further updates to the mortality risk valuation guidance would be forthcoming in the near future. 3 In 1990$, this VSLis $4.8 million. 11 ------- In valuing premature mortality, we discount the value of premature mortality occurring in future years using rates of 3% and 7% (OMB 2003). We assume that there is a "cessation" lag between changes in PM exposures and the total realization of changes in health effects. Although the structure of the lag is uncertain, the EPA follows the advice of the SAB-HES to assume a segmented lag structure characterized by 30% of mortality reductions in the first year, 50% over years 2 to 5, and 20% over the years 6 to 20 after the reduction in PM2.5 (U.S. EPA Science Advisory Board 2004). Changes in the cessation lag assumptions do not change the total number of estimated deaths but rather the timing of those deaths. We express the economic value of the avoided impacts using constant year 2015 dollars, adjusted for growth in real income out to the analysis year using projections provided by the Congressional Budget Office. However, these projections are only available to 2026, so the 2030 estimates use income growth to 2026. Economic theory suggests that WTP for most goods (such as environmental protection) will increase if real income increases. Many of the valuation studies used in this analysis were conducted in the late 1980s and early 1990s. Because real income has grown since the studies were conducted, people's willingness to pay for reductions in the risk of premature death and disease likely has grown as well. We did not adjust cost of illness-based values because they are based on current costs. For these two reasons, the cost of illness estimates may underestimate the economic value of avoided health impacts in each analysis year. As with the selection of health studies, the economic valuation estimates applied in this analysis are consistent with those used in the PM NAAQS RIA. Calculating the benefit per ton estimate The final step is to divide the incidence of adverse health outcomes, and the economic value of those outcomes, associated with the primary PM2.5, nitrate and sulfate attributable to each sector by the sector emissions of directly emitted PM2.5, NOxand SO2. The result is a suite of incidence per ton and $ benefit per ton estimates for each sector. Below we summarize the total $ per ton estimates for each of the 17 sectors, with more detailed health impacts per ton for each sector provided in Appendix A. The results for four analysis years (2016, 2020, 2025 and 2030) are presented. 12 ------- Table 4.

Projected population. The program projects census-reported 2010 population counts to future years using projected population counts from the Woods & Poole corporation. We procured projections developed in the year 2015, which replaced projections last updated in 2012. 2. Baseline and projected death rates. We replaced the existing baseline cause-specific death rates from the years 2004-2006 with rates from the years 2012-2014. We projected these cause- specific rates to the year 2060 using life tables provided by the U.S. Census Bureau. 3. Baseline hospital admission rates. We replaced the baseline rates of hospital admissions and emergency department visits procured from the Healthcare Cost and Utilization Program (HCUP) for the year 2007 with rates for the year 2014. 4. Estimated changes in future income. We substituted projected data from the Congressional Budget Office for the existing Standard and Poors data and projected personal income for each year from 1990 to 2026. The overall influence on the size of the estimated incidence and economic value of air quality changes of these four changes is fairly modest; further information may be found in EPA (2017), linked here. 13 ------- Results Table 5.

Estimates rounded to two significant figures in this table, but all calculations are performed with the unrounded estimates. 21 ------- Lowest Measured Air Quality Level Exposure Assessment Assessments quantifying PM2.5 related health impacts generally find that cases of avoided mortality represent the majority of the monetized benefits. For this reason, EPA has historically performed a series of analyses that characterize the uncertainty associated with the PM-mortality relationship and the economic value of reducing the risk of premature death (Mansfield and Henrion 2009; Roman et al. 2008; US EPA 2012). Here we focus on the level of uncertainty associated with the avoided premature deaths estimated to occur due to air quality improvements below the lowest levels of PM2.5 observed in the epidemiological studies used to quantify such risks. In general, we are more confident in the magnitude of the risks we estimate from simulated PM2.5 concentrations that coincide with the bulk of the observed PM concentrations in the epidemiological studies that are used to estimate the benefits. Likewise, we are less confident in the risk we estimate from simulated PM2.5 concentrations that fall below the bulk of the observed data in these studies. Concentration benchmark analyses (e.g., lowest measured level [LML] or one standard deviation below the mean of the air quality data in the study) allow readers to determine the portion of population exposed to annual mean PM2.5 levels at or above different concentrations, which provides some insight into the level of uncertainty in the estimated PM2.5 mortality benefits. There are uncertainties inherent in identifying any particular point at which our confidence in reported associations becomes appreciably less, and the scientific evidence provides no clear dividing line. However, the EPA does not view these concentration benchmarks as a concentration threshold below which we would not quantify health benefits of air quality improvements.4 Rather, the benefits estimates reported are the best available estimates because they reflect the full range of air quality concentrations associated with the emission reduction strategies and because the current body of scientific literature indicates that a no-threshold model provides the best estimate of PM-related long-term mortality. In other words, although we may have less confidence in the magnitude of the risk at concentrations below these benchmarks, we still have high confidence that PM2.5 is causally associated with risk at those lower air quality concentrations. For a benefit per ton analysis, policy-specific air quality data is not available due to time or resource limitations. For rules using benefit per ton estimates, we are unable to estimate the percentage of premature mortality associated with that rule's emission reductions at each PM2.5 level. However, we believe that it is still important to characterize 4 For a summary of the scientific review statements regarding the lack of a threshold in the PM2.s-mortality relationship, see the Technical Support Document [TSD] entitled Summary of Expert Opinions on the Existence of a Threshold in the Concentration-Response Function for PM2.s-related Mortality (US EPA 2010d). 22 ------- the distribution of exposure to baseline air quality levels as a representation of the starting point for any marginal reductions in air pollution as a result of sector specific emissions reductions. As a surrogate measure of mortality impacts, we provide the percentage of the population exposed at each PM2.5 level in the baseline of the source apportionment modeling used to calculate the benefit-per-ton estimates for this sector. It is important to note that baseline exposure is only one parameter in the health impact function, along with baseline incidence rates population, and change in air quality. In other words, the percentage of the population exposed to air pollution below the LML is not the same as the percentage of the population experiencing health impacts as a result of a specific emission reduction policy. The most important aspect, which we are unable to quantify for rules without rule-specific air quality modeling, is the shift in exposure associated with a specific rule. Therefore, caution is warranted when interpreting the LML assessment for any particular sector rule because these results are not consistent with results from rules that had air quality modeling. Table 13 provides the percentage of the population exposed above and below two concentration benchmarks (i.e., LML and 1 standard deviation below the mean) in the modeled baseline. Figure 3 shows a bar chart of the percentage of the population exposed to various air quality levels in the baseline, and Figure 4 shows a cumulative distribution function of the same data. Both figures identify the LML for each of the major cohort studies. Table 13.

For Krewski, the LML is 5.8 ug/ m3 and one standard deviation below the mean is 11.0 ug/m\ For Lepeule et al., the LML is 8 ug/ m3 and we do not have the data for one standard deviation below the mean. It is important to emphasize that although we have lower levels of confidence in levels below the LML for each study, the scientific evidence does not support the existence of a level below which health effects from e xposure to PM2.5 do not occur. 23 ------- 0.3 Krewski et a I (2009) Lepeule et al.

Cumulative Distribution of Adult Population by Annual Mean PM2.5 Exposure in the Baseline Limitations and Uncertainties This analysis includes many data sources as inputs, including emission inventories, air quality data from models (with their associated parameters and inputs), population data, health effect estimates from epidemiology studies, and economic data for monetizing benefits. Each of these inputs may be uncertain and would affect the benefits estimate. When the uncertainties from each stage of the analysis are compounded, small uncertainties can have large effects on the total quantified benefits. This analysis does not include the type of detailed uncertainty assessment found in the PM NAAQS RIA (EPA 2014; US EPA 2012). However, the results of the Monte Carlo analyses of the health and welfare benefits presented in the PM RIAs can provide some evidence of the uncertainty surrounding the benefits results presented in this analysis. 25 ------- In this analysis we assume that all fine particles, regardless of their chemical composition, are equally potent in causing premature mortality. This is an important 26 ------- assumption, because PM2.5 produced via transported precursors emitted from EGUs may differ significantly from direct PM2.5 released from other industrial sources. However, the scientific evidence is not yet sufficient to allow differentiation of effect estimates by particle type. We also assume that the health impact function for fine particles is linear down to the lowest air quality levels modeled in this analysis. Thus, the estimates include health benefits from reducing fine particles in areas with varied concentrations of PM2.5, including regions that are in attainment with fine particle standard. It is also important to note that the monetized benefit per ton estimates used here reflect specific geographic patterns of emissions and specific air quality and benefits modeling assumptions. Great care should be taken in applying these estimates to emission reductions occurring in any specific location, as these are all based on national emission reduction assumptions and therefore represent an average benefit per ton over the entire United States. The benefit per ton for emission reductions in specific locations may be very different from the estimates presented here. In addition, estimates do not capture important differences in marginal benefit per ton that may exist due to different combinations of reductions (i.e., all other sectors are held constant) or nonlinearities within a particular pollutant (e.g., non-zero second derivatives with respect to emissions). The maps in Appendix B provide an indication of the location of the facilities that were modeled as well as the associated PM2.5 levels. When using these benefit per ton estimates in analyses, care should be taken to not overstate the accuracy of the total benefits estimates or estimates of avoided incidence. For this reason, it is EPA practice to round total benefits estimates to two significant digits and to round estimates of avoided incidence to the nearest whole number. 27 ------- Appendix A: Detailed Results for Each Sector 28 ------- 2016 Analysis Year 29 ------- Table 1: Dollar value (mortality and morbidity) per ton of directly emitted PM2.5 and PM2.5 precursors reduced in 2016 from the cement kilns sector (2015$) Pollutant emitted Directly emitted Mortality risk estimateA N0X SO2 PM2.5 3% Discount Rate Krewski et al.
