Overview

This Technical Support Document (TSD) describes an approach for estimating the

average avoided human health impacts, and monetized benefits related to emissions of 

PM2.5 and PM2.5 precursors including NOx and SO2 from 17 sectors using the results of 

source apportionment photochemical modeling. We focus in particular on the aspects of 

our approach that represent a change from the benefit per ton calculation methodology

described in Fann, Fulcher and Hubbell (2009) and subsequently applied in several EPA 

RIAs. We also describe the ways in which these new estimates can improve our 

characterization of the PM2.5-related health benefits from the sectors that were modeled, as 

well as limitations and uncertainties associated with application of these estimates. We 

summarize the benefit per ton estimates for each of the 17 emission sectors. These sourceapportionment based benefit per ton estimates are also discussed in Fann, Baker and 

Fulcher (2012).

Summary of Calculations

The procedure for calculating benefit per ton coefficients follows three steps, shown 

graphically in Figure 1:

1. Use source apportionment photochemical modeling to predict 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 (BenMAP v4.0.66)1.

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 

NOx emissions.

 1 In this stage we estimate the PM2.5-related impacts associated with changes in directly emitted PM2.5, nitrate 

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 PM2.5 mass to the risk of adverse health outcomes; we do not apply 

effect coefficients that are differentiated by PM2.5 specie.

Figure 1. Conceptual overview of the steps for calculating benefit per-ton estimates

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. Aircraft, locomotives and marine vessels

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

15. Refineries

16. Residential wood combustion

17. Taconite mines

The “Area sources” and “Industrial point sources” categories are agglomerations of 

sectors that were not modeled separately. 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” (US EPA 2011a). 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.

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 NOx and VOC for many of these sectors could be 

substantial. 

Finally, it is important to note that 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 (US EPA 2009). Therefore, reducing these emissions 

would reduce PM2.5 formation, 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 (Federal Register; 40CFR Parts 51, 72, 75, and 96 

Rule to Reduce Interstate Transport of Fine Particulate Matter and Ozone (Interstate Air 

Quality Rule); Proposed Rule. January 30, 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 (Levy et al. 2009). PC-based 
7

tools such as the environmental Benefits Mapping and Analysis Program (BenMAP) can 

systematize health impact analyses by applying a database of key input parameters, 

including health impact functions and population projections(Abt Associates Inc. 2012). 

Analysts have applied the HIA approach to estimate human health impacts resulting from 

hypothetical changes in pollutant levels (Hubbell et al. 2004; Davidson et al. 2007; 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. 2009). This procedure is operationalized 

within BenMAP using a health impact function. 

A typical health impact function looks as follows:

∆y = yo ∙ �eβ∙∆x − 1� ∙ Pop

where y0 is the baseline incidence rate for the health endpoint being quantified (for 

example, a health impact function quantifying changes in mortality would use the baseline, 

or background, mortality rate for the given population of interest); Pop is the population 

affected by the change in air quality, whose size and distribution we have projected to the 

analysis year; ∆x is the change in air quality; and β is the effect coefficient drawn from the 

epidemiological study. 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.

1 We assess these benefits qualitatively due to time and resource limitations for this analysis. 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 confidence 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.

Estimating the economic value of health impacts attributable to each sector

After quantifying the change in adverse health impacts, the next step is to estimate 

the economic value of these avoided impacts. 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 (US EPA-SAB 

2000). The VSL approach is a summary measure for the value of small changes in mortality 

risk experienced by a large number of people.
11

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 (US 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 2000-2012 for the income growth years used in the source apportionment 

benefit per ton calculations.

2012 $8.4 $9.8 $10.1 $10.4

a Income growth projections are only available to 2024, so both the 2025 and 2030 estimates use 

income growth to 2024 and are therefore likely underestimates.

 

2 In the updated Guidelines for Preparing Economic Analyses (US EPA 2010a), EPA retained the VSL endorsed 

by the SAB with the understanding that further updates to the mortality risk valuation guidance woul d be 

forthcoming in the near future.

3 In 1990$, this VSL is $4.8 million.
12

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 (US EPA-SAB 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 2010

dollars, adjusted for growth in real income out to the analysis year using projections 

provided by Standard and Poor’s. However, these projections are only available to 2024, so 

both the 2025 and 2030 estimates use income growth to 2024. Economic theory argues 

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, NOx and 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.

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 et al. 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

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.

a One standard deviation below the mean is equivalent to the middle of the range between the 10th and 25th

percentile. For Krewski, the LML is 5.8 μg/m3 and one standard deviation below the mean is 11.0 μg/m3

. For 

Lepeule et al., the LML is 8 μg/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 exposure to PM2.5

do not occur.

Limitations

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 (US EPA 

2012; US EPA 2006). 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.

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

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.
