- benefit analysis, such an analysis is of particular concern in the current economic climate of sustained unemployment. Executive Order 13563, states, “ Our regulatory system must protect public health, welfare, safety and our environment while promoting economic growth, innovatio n, competiveness, and job creation “ (emphasis added). Therefore, and consistent with recent efforts to characterize the employment effects of economically significant rules, the Agency has provided this analysis to inform the discussion of labor demand and employment impacts. The analysis include s two sets of estimates. The first involves the em ployment impacts on the regulated industry over time. The second involves certain short
-term and on
- going employment impacts (increase in labor demand) associated with the construction of needed pollution control equipment , and other activities, to comply with the regulation. EPA estimates that the net employment effect on the regulated industry will range from −1 5 ,000 to + 30 ,000 jobs , with a central estimate of +8,000 . This aggregate figure includes potential job losses from increased costs as well as potential job increases as a result of additional hiring for compliance. In the pollution control sector, EPA estimates an increase of 46,000 job
- years. EPA also provides a qualitative discussion of other potential employment effects, including both increases and decreases . Because of the uncertainties involved, t hese sets of estimates should not be added in an attempt to characterize the overall employment effect
. The Agency ha s not quantified the rule ’ s effects on all labor in other sectors not regulated by the MATS , or the effects induced by changes in workers ’ incomes. What follows is an overview of the various ways that environmental regulation can affect employment, followed by a discussion of the estimated impacts of this rule. EPA continues to explore the relevant theoretical and empirical literature , which continues to evolve, and to seek public

comments in order to ensure that such estimates are as accurate, useful , and informative as possible. From an economic perspective , labor is an input into producing goods and services . I f regulation leads to more labor be ing used to produce a given amount of output, th e additional labor is reflected by an increase in the cost of production. 2 When a n increase in employmen t occurs as a result of a regulation, it is a cost to firms
. Moreover, when the economy is at full employment, we would not expect an environmental regulation to have an impact on overall employment because labor is being shifted from one sector to anothe r. On the other hand, in periods of high unemployment, employment effects (both positive and negative) are possible. For example, an increase in labor demand due to regulation may result in a short
-term net increase in overall employment due to the potent ial hiring of previously unemployed workers by the regulated sector to help meet new requirements (e.g., to install new equipment) or by the pollution control sector to produce new abatement capital . When significant numbers of workers are unemployed, the opportunity costs associated with displacing jobs in other sectors are likely to be smaller. And , in general, if a regulation imposes high costs and does not increase the demand for labor, it may lead to a decrease in employment. To provide a partial picture of the employment consequences of this rule, EPA investigates the expected consequences for the regulated sector and for the pollution control sector . First, the analysis uses the results of Morgenstern, Pizer, and Shih (2002) to estimate the effects of the regulation on the regulated industry, the electric power industry in this case. This approach has been used by EPA previously in recent Regulatory Impact Analyses. Second, EPA uses information derived from engineering studies and projections of pollution controls from the power sector modeling to generate estimates of employment impacts to the pollution control sector. Section 6.2 discusses the estimates of the employment consequences in the electricity sectors, using the Morgenst ern, et al. approach. Section 6.3 estimates the employment consequences in the pollution control sector.

2 It should be noted that if more labor must be used to produce a given amount of output, then this implies a decrease in labor productivity. A decrease in labor prod uctivity will cause a short
- run aggregate supply curve to shift to the left, and businesses will produce less, all other things being equal.6

**6.2 Employment Impacts Primarily on the Regulated Industry: Morgenstern, Pizer, and**  **Shih (2002)** EPA examined possible employment effects within the electric utility sector using a peer - reviewed, published study that explores historical relationships between industrial employment and environmental regulations (Morgenstern, Pizer, and Shih, 2002). For context, in 2007, the electric power generation, transmission and distribution sector (NAICS 2211) had approximately 510,000 paid employees (a ccord ing to the 2007 Economic Census)
. Estimates from Morgenstern et. al. study have been applied in recent RIAs t o derive the employment effects of new regulations within the regulated industry. (See, for example, the Regulatory Impact Analyses for the proposed MATS and final CSAPR regulations). With certain qualifications, we believe that this study is relevant to this employment analysis, as it was for the MATS proposal, since the pollution control strategies or measures that form the basis of the cost inputs in the Morgenstern et al. analysis are primarily add
- on or end
- of
- line pollution controls, in general cover ing more than 70% of the abatement expenditures in most years and industries analyzed as shown in Table 6
- 1. The analysis of control strategies presented in Chapter 3 of this RIA are composed entirely of add
- on or end
- of
- line pollution controls. Thus, the cost inputs in the Morgenstern et al. analysis are consistent with the cost inputs that enter into this analysis of employment impacts within the regulated industry for MATS. It should be noted that the electric utility sector is less labor
- intensive than the industries examined by Morgenstern et al. (2002). To this extent, it is possible that the positive employment impact estimates are high. **Table 6**  **- 1.**  **Percent of Abatement Expenditures in Different PACE Studies from Add**  **- On or**

The 1984 (1989) data for plastics (pulp and paper) is used instead of 1983 (1988) due to a lack of reported data in the original year.6

Determining the direction of employment effects in the regulated industry is challenging due to competing effects. A regulation that imposes costs may, for that reason, have an adverse effect on employment, but if a regulation leads to the hiring of additional workers, it may, for that reason, have a positive effect on employment. The fundamental insight of Morgenstern, et al. is that environmental regulations can be understood as requiring regulated firms to add a new output (environmental quality) to their product mixes. Although legally compelled to satisfy this new demand, reg ulated firms have to finance this additional production with the proceeds of sales of their other (market) products. Satisfying this new demand requires additional inputs, including labor, and may alter the relative proportions of labor and capital used by regulated firms in their production processes. Thus, Morgenstern et al. decompose the overall effect of a regulation on employment into the following three subcomponents:

 The “Demand Effect”: higher production costs raise market prices, reducing consumpt ion (and production), thereby reducing demand for labor within the regulated industry (an unambiguously negative effect);

 The “Cost Effect”: Assuming that the capital/labor ratio in the production process is held fixed, as production costs increase, plant s use more of all inputs, including labor, to maintain a given level of output. For example, in order to reduce pollutant emissions while holding output levels constant, regulated firms may require additional labor (an unambiguously positive effect) ;

 Th e “Factor
- Shift Effect”: Regulated firms’ production technologies may be more or less labor intensive after complying with a regulation (i.e., more/less labor is required per dollar of output). “ E nvironmental activities may be more labor intensive than con ventional production,” meaning that “the amount of labor per dollar of output will rise.” However, activities may, instead, be less labor intensive because “cleaner operations could involve automation and less employment, for example.” (p. 416) (ambiguous effect) Decomposing the overall employment impact of environmental regulation into three subcomponents clarifies the conceptual relationship between environmental regulation and employment in regulated sectors, and permitted Morgenstern, et al. to provide an empirical estimate of the net impact. For present purposes, the net effect is of particular interest, and is the focus of our analysis. The demand effect is expected to have a n unambiguously negative effect on employment, the cost effect to have a n unambiguously positive effect on employment, and the factor
- shift effect to have an ambiguous effect on employment. Without more information with6

respect to the magnitudes of these three competing effects, it is not possible to predict the net employment e ffect in the regulated sector . Using plant
- level Census information between the years 1979 and 1991, Morgenstern et al. estimate the size of each effect for four highly polluting and regulated industries (petroleum, plastic material, pulp and paper, and st eel). On average across the four industries, each additional $1 million ($1987) spending on pollution abatement results in a (statistically insignificant) net increase of 1.55 (+/
- 2.24) jobs. As a result, the authors conclude that increases in pollution a batement expenditures can have positive effects on employment and do not necessarily cause economically significant employment changes. The conclusion is similar to Berman and Bui (2001 ) , who found that increased air quality regulation in Los Angeles did not cause in large employment changes. Ideally, the EPA would first apply the methodology of Morgenstern et al. to current pollution expenditure and market data for the regulated firms to identify the relationship between abatement costs and employment, t hen use this relationship to extrapolate the effect of new projected abatement costs on these firms. Unfortunately, current firm
- level abatement cost and market characteristics are not available. Therefore, the EPA has used the estimated relationship fro m the Morgenstern et al. data to extrapolate the employment impact of the new projected abatement costs without accounting for the industry and firm differences. Since the Morgenstern, et al. parameter estimates are expressed in jobs per million ($1987) 4 of environmental compliance expenditures, their study offers a transparent and simple way to transfer estimates for other employment analysis. For each of the three job effects outlined above, EPA used the Morgenstern et. al. four industry average paramete rs and standard errors along with the estimated private compliance costs to provide a range (based on the 95th percentile of results) of employment effects in the electricity sector associated with the rule. By applying these estimates to annualized cost for the final rule for the electric power sector as shown in Chapter 3 of this RIA ($9.60 billion in 2007$) , the Agency estimated each effect. The results are:

 Demand effect: −39,000 to +2,000 jobs in the directly affected sector with a central estimate of −18,000;

4 The Morgenstern et al. analysis uses “production worker” as defined in the US Census Bureau’s Annual Survey of Manufactures (ASM) in order to define a job. This definition can be found on the Internet at http://www.census.gov/manufacturing/asm/definitions/index.html6
- 6  Cost effect: +4,000 to +21,000 jobs in the directly affected sector with a central estimate of +12,000; and

 Factor - shift effect: +200 to +27,000 jobs in the directly affected sector with a central estimate of +14,000. EPA estimates the net employment effect to range from −1 5 ,000 to + 30 ,000 jobs in the directly affected sector with a central estimate of +8,000. 5 , 6 EPA recognizes there will be other employment effects that are not considered in the Morgenstern et al. study. For example, employ ment in pollution control industries may increase as firms purchase more pollution control equipment and services to meet the rule’s requirements. EPA does provide such an estimate of employment change later in this section in a separate analysis. A defen sible methodology for evaluating the employment impacts beyond the pollution control and regulated sectors is not yet available, though as noted before , net effects on employment are expected to be at or very close to zero for the economy overall under fu ll employment. Attempts to estimate such effects usually rely on input
- output methodologies that hold technologies and the proportion of various inputs constant over time, making them inappropriate for estimating long run impacts of regulation. **6.2 .1**  **Limi tations**  The Morgenstern et al. approach to employment analysis has the advantage of carefully controlling for many possibly confounding effects in order to separate the effect of changes in regulatory costs on employment. Although the Morgenstern et al. paper prov ides information about the potential job effects of environmental protection programs, however, there are several caveats associated with using those estimates to analyze the final rule. First, the Morgenstern et al. estimates presented in Table 6
- 2 and us ed in EPA’s analysis represent the weighted average parameter estimates for a set of manufacturing industries (pulp and paper, plastics, petroleum, and steel). Unfortunately this set of industries does not overlap directly with the electric utility sector. Second, relying on Morgenstern et al. implicitly assumes that the employment estimates derived from 1979 – 1991 data are still applicable. Third, the methodology used in Morgenstern et al. assumes that regulations affect plants in proportion to

5 Since Morgenstern’s analysis reports environmental expenditures in $1987, we make an inflation adjustment the IPM costs using the ratio of the annual consumer price index, U.S. city, all items reported by the U.S. Bureau of Labor Statistics: CPI 1987/ CPI 2007 = (113.6/207.3) = 0.55. 6 Net employment effect = 1 .5 5 × $9,6 00 million × 0. 55. Given the 95% confidence interval for this effect, this estimated net result is not statistically different from zero.6

their total costs. In other words, each additional dollar of regulatory burden affects a plant by an amount equal to that plant’s total costs relative to the aggregate industry costs. By transferring the estimates, EPA assumes a similar distribution of regulatory cost s by plant size and that the regulatory burden does not disproportionately fall on smaller or larger plants. EPA also assumes that the net employment impact can be linearly extrapolated from the abatement cost (i.e., that every million 1987 dollars genera tes a central estimate of 1.55 jobs). Fourth, the Morgenstern et al. analysis makes particular assumptions about the role of imports and the effect of previous regulation on plant closures. While imports are not an issue for MATS , the stringency of the current regulation is expected to result in a number of power plant closures due to early retirement of coal
- fired EGU capacity in 2015, as indicated in Chapter 3 of this RIA. Finally, the Morgenstern et.al. methodology does not examine the effects of regulation on employment in sectors related to , but outside of the regulated sector . However, it does suggest that the relationship between the employment impact in any sector and increased costs due to regulation is ambiguous. **Table 6 -**  **2 .**  **Employment Impac ts**  **Within the Regulated Industry Using Peer** **- Reviewed Study**

**6.3 Employment Impacts of the MATS**  **- Pollution Control**  **Sector Approach by 2015 7**  Regulations set in motion new orders for pollution control equipment and services. New categories of employment have been created in the process of implementing environmental regula tions. When a regulation is promulgated, one typical response of industry is to order pollution control equipment and services in order to comply with the regulation when it becomes effective , while closure of plants that choose not to comply occurs after the compliance date . With such a response by industry as a basis, this section presents estimates for short term employment needed to design, construct, and install the control equipment in the three or four year period leading up to the compliance date. Environmental regulation may increase revenue and employment in the environmental technology industry. While these increases represent gains for that industry, they are costs to the regulated industries required to install the equipment. As with any poo l of labor, the gross size of the labor pool does not reflect the net impact on overall employment after adjusting for shifts in other sectors. Regulated firms hire workers to design and build pollution controls. Once the equipment is installed, regulated firms hire workers to operate and maintain the pollution control equipment – much like they hire workers to produce more output. Of course, these firms may also reassign existing employees to do these activities. Environmental regulations also support employment in many basic industries. In addition to the increase in employment in the pollution control industry ( to fill increased orders for pollution control equipment placed by the regulated sector ), environmen tal regulations also support employment in industries that provide intermediate goods to the pollution control industry. For example, an investment in capital expenditures to reduce air pollution involves the purchase of abatement equipment. The equipmen t manufacturers, in turn, order steel, tanks, vessels, blowers, pumps, and chemicals to manufacture and install the equipment. A study by Bezdek, Wendling, and DiPernab (2008) found that “ investments in environmental protection create jobs and displace job s, but the net effect on employment is positive. ” 8 The majority of the jobs associated with added pollution controls (e.g., boilermakers, general construction workers, etc.) will provide domestic employment opportunities, but some goods and services deman ded and/or provided to the pollution control industry (e.g., steel, cement, etc.) are internationally traded goods.

7 EPA expects that the installation of retrofit control equipment in response to the requirements of this proposal will primarily ta ke place within 3 years of the effective date of the final rule, but there may be a possibility that some installations may occur within 4 years of the effective date. 8 Environmental protection, the economy, and jobs: National and regional analyses , Roge r H.

The focus of this part of the employment analysis is on short
-term employment related to the compliance actions of the affected entities. T his analysis estimates the employment impacts due to the increased demand for pollution control equipment in response to MATS. 9 Results indicate that the MATS has the potential to result in a net increase of labor in these industries, driven by the high demand for new pollution controls. Overall, the results of the pollution control sector approach indicate that the MATS could sup port an increase of about 46 ,000 job
- years 10 by 2015 . **6. 3**  **.1 Overall Approach and Methodology for**  **Pollution Control Sector Approach**  EPA developed estimates of the potential employment changes for the Pollution Control Sector using a bottom
- up engineering bas ed methodology combined with macroeconomic data on industrial output and productivity, to estimate employment impacts. The approach relies heavily on the projections and cost ing analysis from the IPM model, which uses industry specific data and assumption s to derive compliance costs and energy impacts (See Chapter 3 )
. Central to t he approach are prior EPA studies on similar issues, and in particular, data and information from extensive engineering studies that the Agency has commissioned . 11 The analysis d evelops employment estimates by relying on IPM projections from the MATS analysis for the specific types of pollution control technologies expected to be installed to comply with the rule. 12 More specifically, the analysis includes estimates for the labor needed to design, manufacture and install the needed pollution control equipment over the 3 to 4 years leading up to compliance in 2015. For construction labor, the labor needs are derived from an update to a 2002 EPA resource analysis for building various pollution controls (FGD
– Flue Gas Desulfurization or scrubbers, SCR
- selective catalytic reduction, ACI – activated carbon injection, DSI
- dry sorbent injection, and FF
- Fabric Filters) and are further classified into different labor categories. These categories include boilermakers, engineers and a catch
- all “ other” installation labor. For the inputs needed (e.g., steel), the updated 2002 resource study was used to determine the steel

-time individual for a year (or FTE). For example, 25 job years may be equiva lent to five full
-time workers for five years, twenty
-five full
-time workers for one year, or one full
-time worker for twenty

More detail on methodology, assumptions, and data sources can be found in Appendix 6A for this RIA. Projections from IPM were used to estimate the incremental retrofit capaciti es projected in response to the final rule. These additional pollution controls are shown in Table 6

**6. 3**  **.3 Other Employment Impacts of**  **MATS** In addition to the employment impacts estimated for the regulated sector and pollution control sectors, t here are likely to be other employment impacts associated with MATS . These include changes resulting from labor needed to operate the needed pollution controls, increased demand for materials used in pollution control operation, shifts in demand for fuel in response to the rule, changes in employment resulting from additional coal retirements, and changes in other industries due to changes in the price of electricity and natural gas. 14 The EPA has provide d estimates of some of these effects below, whi ch are discussed in more detail in Appendix 6A. The most notable of those that the Agency is unable to estimate are the impacts on employment as a result of the increase in electricity and other energy prices in the economy. Nor is the Agency able to quantify all the employment changes in industries that support and supply the pollution control industry. Because of this inability to estimate all the important employment impacts, EPA neither sums the impacts that the Agency is able to estimate for the se other employment impacts or make any inferences of whether there is a net gain or loss of employment across the se categories . A summary of the other employment impacts can be found in Table 6

Firms can respond to price changes by making changes to their processes, raising their prices, reducing production, etc. However, electricity expenditures are only a modest component of overall economic activity. On an expenditures
- weighted basis, electricity comprises only 0.75% of total production expenditures across all sectors in 2002 (BEA, 2007b, 2007c). 15 As report ed in Chapter 3, the Retail Electricity Price Model forecasts a 3.1% increase in the contiguous U.S. electricity price in 2015 (see Table 3
- 12) as a result of MATS
. Therefore, the upper estimate o f the initial increase

15 The BEA’s benchmark I/O summary - level data includes information on the share of expenditures by industry spent on 135 commodity categories for 133 different sectors. These data provide a “ comprehensive pict ure of inner workings of the economy” (Stewart et al., 2007). For more detail, see BEA 2007a and 2009.6

in production costs across all sectors from direct electricity expenses is 0.023% ( = [0.031 * 0.0075]*100% ). 16 This 0.023% increase in average production expenditures represents a credible upper estimate o f the average direct effect of higher electricity expenses because it assumes that production, consumption, and input levels do not change in the economy. 17 In reality, we know that producers and consumers can often use less electricity
- intensive substitute goods and services to avoid a significant portio n of these costs even in the short
- run, which would mitigate these production cost increases. We also know that producers of intermediate goods and services that adjust to higher electricity prices can also make changes that lead to price adjustments for final goods and services sectors (as discussed below, indirect electricity price effects are not included in this illustrative estimate)
. Taking into account the fact that these numbers represent an upper estimate o f initial production costs from the dire ct increase in electricity expenditure s , EPA does not expect that increases in average production expenses from direct electricity price changes in this range are sufficient to cause significant shifts in overall economic activity outside the electricity s ector and its major input markets. Note that this per unit percent cost increase does not reflect other potential economic effects of this rule. For example, the increased expenditures on pollution abatement equipment could create more demand for labor i n those industries. Alternatively, as producers switch away from electricity
- intensive inputs, the demand for other inputs may increase, changing the cost of production for those factors of production. This estimate has a number of limitations. First, as mentioned above, it reflect s an upper estimate on the initial change to the average production cost of goods and services from direct electricity expenses because the calculation used to estimate these changes assume s that production, consumption and in put use will not change in response to higher electricity prices. Second, as mentioned above, this analysis also does not account for the effect that higher electricity prices have on the factors used by other sectors (e.g. the cost of components and othe r inputs). For sectors that use both electricity and other energy
- intensive inputs, the effect of higher electricity prices on input prices can be important but applying the BEA data to account for the indirect effect of electricity price pass
- through on factors relies even more

16 Note that we are only performing simple calculations for upper estimate increases in per unit production costs as a direct consequence of higher elect ricity prices. A modeling approach would require assumptions about behavioral response to price changes, and we are assuming for this analysis that there is no behavioral response to higher electricity prices. 17This means that all other inputs, includin g capital, labor, and materials are assumed to be fixed when generating an upper estimate per unit production expense from direct electricity prices for the industries included in this analysis.6

heavily on assumptions about the inability of sectors to change their factor mix in response to relative factor prices changes. Third, important differences across sectors, regions and consumer classes may be masked by the nationw ide estimate d average expenditure changes. However, because the Retail Electricity Price Model does not estimate price changes for different customer classes, and because the BEA data does not provide a regional decomposition of the economic accounts suit able to calculating regional upper estimates on per unit production expenses , regional and consumer class price differences cannot be calculated. Similarly, there are sectors that will have a meaningfully higher or lower maximum increase in average production expenditures within the context of the national average. Fourth, the share of electricity used may have changed since 2002. In general, electricity consumption per dollar of gross domestic product fell from 2002 through 2009, but electricity expendit ures relative to gross domestic product rose slightly over this time (EIA, 2011; BEA 2011). Not accounting for this change over time in expenditures on electricity may lead to a slight underestimate of the increase in average production expenditures, avera ged across the entire economy, as a result of this rule. While there are several caveats to this approach, this calculation suggests that electricity prices under MATS are not expected to have a large impact on production cost s for the economy as a whole. Initial p roduction cost impacts of less than 0.023% from direct electricity expenditures are unlikely to lead to significant impacts on the overall economy and would fall within the normal variability range of input price variation observed by producers in the past . This is consistent with the overall history of the implementation of the Clean Air Act (Jaffe et al., 1995). This upper estimate of average initial production cost increases from direct electricity expenditures cannot be used to estimate changes in employment as a result of the regulation, either nationally or for individual sectors. First, as noted above, these calculations do not account for the ability of the real economy to adjust to changes in price through input substitution, technological innovation, or other means . It is necessary to account for changes in production, consumption, and input use to estimate the change in total employment. Second, this approach does not account for changes in consumer and p roducer behavior as they adjust the quantity of goods and services supplied or demanded in all of the markets affected by the regulation. Changes in employment (both increases and decreases) in downstream sectors will reflect the balance of all of these i nteractions. A n evaluation of the employment impacts beyond the pollution control and regulated sectors is not yet available, though as noted before, net effects on employment are expected to6

be at or very close to zero for the economy overall under full employment. In the case of this rule, labor may be a complement or a substitute to electricity in production, depending on the sector. It is also the case that environmental regulation may increase labor productivity by improving health, which may incre ase employment ( via an increase in overall economic productivity, see the discussion in Chapter 5). Attempts to estimate such economy
- wide effects by hold ing technologies and the proportion of various inputs constant over time are inappropriate for estima ting long run impacts of regulation and an inaccurate representation of the behavior of real
- world firms. **6.6 Estimating Social Cost and Economic Impacts**  In the Transport Rule proposed in the summer of 2010 and in other rulemakings, EPA used a different m odel to estimate the social cost and economic impacts of the regulatory approach than the model applied in this RIA. That model, EPA’s EMPAX, is a CGE model that dynamically cascades the cost of a regulation through the entire economy. Since that rule was proposed, a different version of EMPAX was used to estimate the social cost of the Clean Air Act in a new EPA report entitled “The Benefits and Costs of the Clean Air Act from 1990 to 2020” (EPA, 2010, herein referred to as the Section 812 report). This ve rsion of EMPAX accounts for the benefits of reducing pollution on labor productivity and on the demand for health care, which significantly influenced the model’s estimates of the social cost and economic impacts of the Clean Air Act relative to an analysi s using EMPAX in which these benefits
- related effects were not accounted for. In December 2010, in its review of the 812 Report EPA’s Science Advisory Board (SAB) found that “The inclusion of benefit
- side effects (reductions in mortality, morbidity, and he alth
- care expenditures) in a computable general equilibrium (CGE) model represents a significant step forward in benefit
- cost analysis” (SAB, 2010). A description of the changes to the model and implications are described in detail in chapter 8 of the Sect ion 812 report. EPA has determined that it needs to update the EMPAX model version used for RIAs to account for these beneficial effects of reducing pollution prior to its use in any additional regulatory analysis. The EMPAX model version used for the Sect ion 812 report cannot be used for this rulemaking because it contains energy and economic data that are consistent with the multi
- year timeframes and energy scenarios of the 812 study but not with the single target year, analysis timeframe, and energy scen ario most appropriate for this current rulemaking analysis. For example, much of the energy data in the EMPAX model employed in the Section 812 report is from the Energy Information Administration’s Annual Energy Outlook 2005. With these impacts of reducin g pollution on labor productivity and the demand for health care now in the process of being incorporated into the model, the SAB’s perspective on the desirability of accounting for these effects in the CGE analysis for the 812 study, and the typical pract ice by6

EPA’s Office of Air and Radiation of having analyses within RIAs to be consistent in design with those included in the most recent available Section 812 report, EPA will not use EMPAX for this RIA. **6.7 References**  Berman, E., and L.

- 1 **APPENDIX 6A EMPLOYMENT ESTIMATES**  **OF DIRECT LABOR IN R ESPONSE TO THE MERCU**  **RY AND AIR TOXICS STANDARDS IN 2015**  This appendix presents the short
- term employment estimates of the Mercury and Air Toxics Standards (MATS), henceforth referred to as the final MATS. The focus of the employment analysis in this study is only on the first order employment impacts related to the compliance actions of the affected coal
- fired entities within the power sect or. 18 It does not include the ripple effects of those impacts on the broader economy (i.e., the “multiplier” effect), nor does it include the wider economy
- wide effects of the changes to energy markets (such as higher electricity prices). 19 Moreover, this study provides only a static snapshot of the impacts for 2015 and does not account for the dynamic adjustments of the affected entities as they adapt to the final MATS, such as those arising from technological innovation and learning
by
- doing. This analys is is also independent of other techniques used by the U.S. EPA to estimate certain employment effects of particular regulations. The estimates of the employment impacts are divided into several categories: job gains due to the increased demand for polluti on control equipment; job losses due to retirements of coal capacity; and job shifts due to changes in demand for fuels. The various employment metrics can also be distinguished by one
-time employment changes (e.g., pollution control construction), and on going employment changes (e.g., fuel use changes and pollution control operation or coal retirements). Results indicate that the final MATS has the potential to provide significant short
-term employment opportunities, primarily driven by the high demand for new pollution control equipment. The employment gains related to the new pollution controls are likely to be tempered by some losses due to certain coal retirements, although, as discussed below, some of these workers who lose their jobs due to plant r etirements could find replacement employment operating the new pollution controls at nearby units. Finally, job losses due to reduced coal demand are expected to be offset by job gains due to increased natural gas demand, resulting in very small positive (i.e., less than three hundred) net change in employment due to fuel demand changes. Overall, the preliminary results indicate that the final MATS could support a net of slightly over 46,000 one
- time job
- years and a net of about 6, 0 00 ongoing job
- years in 2015. These results are summarized in Table 6A
- 1 below.
18 This analysis does not include potential employment effec ts resulting from projected impacts on oil/gas
-fired units. 19 For more detail on the economic impacts of the proposed rule, see Chapter 3 of the Regulatory Impact Analysis accompanying final MATS.6A

MATS is not anticipated to result in any notable new capacity in response to the rule, and thus is not considered as part of this analysis. b Totals may not add due to rounding . The job
- years estimated here is a snapshot of the first order employment effect of the final MATS in 2015. While there is no temporal dimension to this study, some of these jobs are likely to be spread over several years, and som e will last longer. Most of the construction related labor demand, for example, is expected to provide a short
-term, temporary boost to employment that could last two or three years, along with any “multiplier effects” (i.e., secondary employment supporte d in upstream sectors) that are not included in these job
- year estimates. Most of the operational labor needs and labor shifts resulting from fuel changes are likely to be longer term. Thus, in terms of the impacts of the final MATS on economy
- wide emplo yment over time, this analysis shows there could be a significant temporary increase to employment levels starting well before 2015, which would likely recede thereafter as the construction phases for the needed pollution controls wind down. Over time, th e operational jobs will continue to provide a small boost to employment over “business as usual” baseline employment levels. Note that this synopsis does not account for other employment impacts of the final MATS, such as those resulting from higher energ y prices. **6A.1 Overall Approach**  The estimates for the near
- term employment effects of the final MATS utilize studies conducted by EPA on engineering and resource requirements for various compliance activities, such as installing pollution control equipment, switching fuels, or ceasing plant operations as they become uneconomic. Some of the information used here was obtained from a 2002 EPA engineering study for multi
- pollutant control strategies. 20 This study was also the basis for the employment analysis for the proposed MATS. For the final MATS, EPA has undertaken a separate study to update the 2002 analysis in order to refine and update the Agency’s understanding of the resource requirements (labor and materials) of various compliance

activitie s, including estimates for newer pollution control equipment that were not included in the 2002 analysis. 21 For example, the 2002 study focused on pollution control technologies that directly address SO 2 and NO x emissions, while the updated study also incl udes pollution control technologies that reduce mercury emissions and hazardous air pollutants as well. Collectively, these studies are referred to as EPA pollution control studies in this appendix. This employment analysis is based on information from t he updated study where available, as well as data from the original 2002 study, where updated information was unavailable. The basic approach involved using power sector projections and various energy market implications under the final MATS from modelin g using EPA’s data and assumptions with the Integrated Planning Model (IPM), along with data from secondary sources, to estimate the first order employment impacts for 2015. Throughout this analysis, incremental employment is measured in job
- years, since there is no temporal dimension to this analysis. 22 Also, this appendix does not include estimates of total employment impacts over time , though there is a distinction between short
- term construction related labor needs and more long
-term operational labor needs for new pollution controls (though these operational labor requirements are also measured in 2015 job
- years only). **6A.1.2 Employment Changes due to New Pollution Control Equipment**  EPA’s IPM projections for the final MATS policy case were used to e stimate the incremental pollution control demand. These are shown in Table 6A
- 2 below: 23 Note that the capacity estimates shown in Table 6A
- 2 do not include EPA’s projections for ESP and FGD upgrades on existing units. Because the engineering studies used in this employment analysis do not include resource estimates for these technologies, EPA chose not to analyze the employment impacts for these technologies. This exclusion is likely to understate the total employment impacts for the final MATS.

21 Engineering and Economic Factors Affecting the Installation of Control Technologies – An Update . Andover Technology Partners and ICF International. October 20, 2011. 22 A job
-year is defined as the amount of work that can be performed by the equivalent of one full
-time individual for one year (or FTE). 23 According to IPM, there is some overlap between the different types of pollution control equipment demand at individual facilities. To the extent that there could be some efficiency gains at plants installing multiple controls due to economies of scale, the job estimates presented here could overstate the impacts.6A

The labor needed for constructing and installing these controls are for construction
- related sectors, such as boilermakers, engineers, and other installation labor. The two categories of labor ne eds for ongoing resource requirements include employment in sectors that supply resources needed to run these pollution controls (such as reagents); and utility sector jobs to operate the control equipment. The following sections discuss the approach for each:

 For the construction labor estimates, per
- unit labor needs were taken from the pollution control studies, which included man
- hours required per MW for each of the control technologies listed above. The total installation labor was then sub
- divided i nto different labor categories, such as boilermakers, engineers and a catch
- all “other installation labor”, using estimated shares of the different labor types in the EPA pollution control studies.

 For the longer term labor associated with operating the pollution controls , per- unit estimates of the main resources needed for the particular types of equipment (see Table 6A
- 3 below for a list of the resources) are also taken from EPA’s pollution control

24 In addition to the scrubber capacity show n in Table 2, EPA also projects an additional 2.6 GW of dry scrubbers on units burning waste coal and pet. coke and have existing baghouses. This capacity is not included in the table above, however, employment impacts associated with these controls are i ncluded in this appendix as discussed below. 25 This number includes the total incremental fabric filters, as reported in Chapter 3. For the purpose of estimating the construction jobs from fabric filters this appendix uses an incremental capacity of 84 G W (i.e., incremental fabric filters that are standalone, or installed with DSI or ACI+Toxecon). To avoid double counting, the remaining 18 GW of fabric filters that represent those installed on units with dry scrubbers are excluded from the employment ana lysis, under the assumption that the labor estimates for dry scrubbers include resources required for both the scrubber as well as the fab ric filter that goes with it.6A

studies. Resources needed for FF (such as the filter b ags) were estimated from the incremental Variable Operation and Maintenance (VOM) costs from EPA’s IPM modeling results. 26 These were then multiplied by the incremental GW for each pollution control to obtain the total (physical) quantity of resources need ed. Total tonnage for each resource was then converted to dollars of increased economic output for these resources using price estimates developed by Sargent & Lundy for EPA’s IPM Base Case v4.10 modeling assumptions (see notes at the end of Table 6A
- 3 be low). Finally, the labor productivity for each particular sector was used to estimate the number of job
years these could create in 2015. Labor productivities for each sector were adjusted to account for increased worker productivity in 2015. Data for b aseline worker productivity and corresponding growth rates to account for future productivities came from the Economic Census and the Bureau of Labor Statistics (BLS) estimates. 27

 The final employment vector estimated was for the utility sector labor neede d to operate these pollution control equipment. This estimate was based on the incremental Fixed Operation and Maintenance (FOM) costs from EPA’s IPM modeling results, excluding costs due to retirements. Thus, this study assumes that the FOM costs are a r easonable proxy for the payroll costs that are part of the FOM costs in EPA’s modeling (FOM costs are defined as the operating and maintenance costs incurred by the utility, such as those for payroll, irrespective of whether the equipment is operated). Th e FOM costs were then translated into employment based on estimates of payroll per worker for the power sector taken from the 2007 Economic Census and BLS estimates. 28

26 Because FF requirements are not endogenously determined in IPM, it required a differen t approach than the other controls. 27 Total value of shipments in 2007 and total employees were taken from 2007 Economic Census, Statistics by Industry for Mining and Manufacturing sectors. The average annual growth rate of labor productivity was taken fr om the Bureau of Labor Statistics. Average growth rate calculated for years 1992
- 2007, applied to 2007 productivity to determine 2015 estimates of productivity. See the Detailed Methodology section at the end for more details about the data used for thes e calculations. 28 Same sources as other productivity estimates (2007 Economic Census and BLS), however, uses employees and total payroll rather than revenue or value of shipments.6A

- years to design, construct, and operate the needed pollution control equipment in 2015. Note, some of these jobs are expected to start before, and continue beyond 2015 (such as the resource related job
- years), but this analysis only provides a snapshot for 2015
.

29 For FGD this study uses the price for Lime (Dry FGD) which is signific antly greater than the Limestone (Wet FGD) price. This price was used because EPA’s modeling indicates most of the incremental FGD units are likely to be dry scrubbers.6A

- years estimated for pollution control installation (i.e., “Jobs for Construction” in Table 6A
- 4 above) is driven in large part by the demand for new FFs used in EPA’s modeling. As shown in Table 6A
- 2, up to 84 GW of new FF capa city is projected to come online in 2015 due to the final MATS that are relevant for this employment analysis. The demand for new FFs is estimated to contribute nearly 70 percent of the new employment resulting from the installation of pollution controls. Moreover, of the labor needed due to increased resource use, the Trona required for DSI is estimated to support higher number of jobs than the other resources. This is because the DSI technology requires significantly higher quantities of reagents than the other pollution controls, based on EPA’s engineering estimates and pollution control studies. The second highest resource
- related employment gains would likely come from the activated carbon needed in response to the final MATS. Of the roughly 54,50 0 job
- years estimated in Table 6A
- 4, about 4,300 job
-years, or about 8 percent, are estimated to occur within the utility sector for labor needed to operate the pollution controls (referred to as “Jobs for Pollution Control Operation” in Table 6A
- 4). The rest of the labor demand will benefit the pollution control industry and other economic sectors. The increased demand for resources and chemicals needed to operate the pollution controls will result in increased employment in sectors such as mining, chemi cals, and other6A
- 8

manufacturing sectors. The majority of these first order employment effects, however, are likely to benefit construction
- related sectors, such as construction, boilermaker, heavy engineering, and other heavy construction sectors, resulting from the construction and installation of the new pollution controls at affected sources throughout the country. 6A.1.3.1 Employment Changes due to Coal Retirements Employment changes due to incremental coal plant retirements were estimated by first identifying the retiring coal units 30 from EPA’s modeling results (for the base and the final MATS policy cases). EPA projects roughly 4.7 GW of additional coal retirements by 2015 with the final MATS in place. 31 In order to convert the retired coal capac ity into potential employment losses, it was assumed that changes in the operating costs for the retired coal units can be used as a proxy for payroll expenditures and the lost economic output due to coal retirements. Thus, the changes in the FOM costs for these particular retiring units were derived using EPA’s IPM modeling results, and converted to lost jobs using data from the Economic Census and BLS output/worker estimates for the utility sector. 32 Employment losses due to plant retirements will not onl y affect those that are directly working at the plant (i.e., plant operators), but would also affect administrative and other “back
- office” workers for those utilities and their support organizations. This appendix assumes that the FOM costs related to re tiring plants are a good proxy for these types of job losses. **Table 6A** **- 5: Annual Job Losses due to Coal Capacity Retirements for 2015**  FOM Decrease from Retirements (million) $288 Workers Per Million$ in payroll 8.7 **Workers lost due to retirements (job**  **- year):**  **2,500**

30 Oil and gas steam unit emissions requirements, and potential retirements, were not directly included in EPA’s IPM modeling under the MATS policy scenario. An analysis of these units was conducted separately, and to the extent that there may be some retirements of oil and gas units, then the estimates of potential job losses due to reti rements provided here will understate the employment losses. 31 Retirement estimates are based on IPM System Summary Reports from EPA’s modeling runs . Where applicable, data from IPM parsed outputs were adjusted to account for partial retirements reported in the parsed outputs. 32 The same specific sources as cited before, however, used workers and total payroll.6A
- 9

Results indicate there could potentially be about 2,500 job losses (measured in job
- years for 2015, but any net job losses under this category are likely to be permanent), due to coal retirements. However, two mitigating factors could reduce the negative employment impacts due to retirements. First, many of the retiring units are at plants that are likely to have other units operating under the policy scenario. In such cases, some of the excess labor pool at the retiring units could well be absorbed at other units within the same firm. Second, as Table 6A
- 4 indicates, utilities are expected to have the need to fill about 4,300 additional job slots to operate the pollution controls needed to meet the requirements of the final MATS. If workers with experience at existing coal facilities become available thro ugh plant retirements, some of these workers could be absorbed in operating these new pollution controls. 6A.1.3.2 Employment Changes due to Changes in Fuel Use Employment impacts due to projected fuel use changes (coal and natural gas production shifts) were estimated using EPA’s modeling results. First, employment losses due to reductions in coal demand were estimated using an approach similar to EPA’s coal employment analyses under Title IV of the Clean Air Act Amendments. 33 Using this approach, EPA’s projected coal demand changes (in short tons) for various coal supplying regions were converted to job
- years using EIA data on regional coal mining productivity (in short tons per employee hour), using 2008 labor productivity estimates. 34 , 35 Results of th e coal employment impacts of the final MATS are presented in Table 6A
- 6 below.

In general, labor productivity for the fuel sectors (both coal and natural gas) showed a significantly higher degree of variability in recent years than the manufacturing sectors, which would have introduced a high degree of uncertai nty in forecasting productivity growth rates for future years.6A

Most secondary data sources (such as Census and EIA) provide estimates for the combined oil and gas extraction s ector. This appendix thus uses an adjusted labor productivity estimate for the combined oil and gas sector that accounts for the relative contributions of oil and natural gas in the total sector output (in terms of the value of energy output in MMBtu). Th is estimate of labor productivity is then used with the incremental natural gas demand for the final MATS to estimate the job
- years for 2015. **Table 6A** **- 7: Annual Employment Impact due to Changes in Fuel Use (2015)**  **Fuel Type Employment**  **Coal Job Years Lost**  **(430) Natural Gas**  Incremental Natural Gas Use (MMBtu) 175,786,505 Labor Productivity (MMBtu/job
-year) 261,840 **Job -** **years gained 670**  **Net Employment Effects of Fuel use changes 240**  Note: Totals may not add due to rounding Thus, about 430 job losses in the coal mining sector are likely to be offset by about 670 job gains in the natural gas production related sectors, for a net effect of about 240 job
- year gains due to the changes in fuel use. The changes in coal mining emp loyment is driven by a significant increase in demand for Interior coal which leads to about the same amount of job gains as is lost due to the decreased demand for Appalachian coal (see Table 6A
- 6 above). This,6A
- 11

coupled with the fact that there is likely to be some job gains due to increased demand for natural gas, results in a small net job gain due to fuel use changes for the final MATS. **6A.2 Results Summary**  Overall, the final MATS is expected to provide a n increase to short
- term employment resulting from substantial investments in new pollution control equipment. For 2015, the results indicate the final MATS could support or create around 46,000 job
-years driven by the need to design and construct the nee ded equipment. While there could be some employment losses due to coal retirements that will likely have a negative effect on some utilities and the coal mining sector, employment gains in pollution control operation activities and the natural gas sector are likely to offset some of those losses. As previously discussed, this assessment does not account for the long
- run economy - wide effects of the final MATS. **6A.3 Detailed Methodology**  This section provides more details on the data and approaches used to estimate the employment impacts discussed above. The section also details the sources for individual data elements. **6A.3.1 Pollution Control Equipment Labor**  6A.3.1.1 Installation Labor **Table 6A** **- 8: Installation Labor Requirement**  **36 Pollution**  **Control Type**  **Incremental GW**

Development Methodology FINAL”, August 2010, Project 12301
- 007, Perrin Quarles Associates, Inc. Labor related to resources used in operating pollution control equipment was estimated using the total incremental GW of pollution control capacity which was first converted to total MWh of incremental capacity assuming 85 percent capacity factor. For each pollution control type, the next step involved choosing the primary operating resource. Th is approach is consistent with prior EPA’s analyses on similar topics. The next step involved estimating the resource needs by each control type, generally in tons of material using the resource usage estimates as shown in Table 6A
- 9. Using the total usag e for each pollution control input (in tons) and associated average prices, total expenditure by each resource type was then calculated. This total expenditure was then converted to labor using workers per $Million in total output for the industry associa ted with producing each respective input material. 39 6A.3.1.3 Operating Labor **Table 6A** **- 10**  **: Operating Labor Assumptions** Incremental FOM from IPM Parsed ($ Billion) 2.20 FF and other Capital Costs Included in FOM ($ Billion) 1.70 Remaining FOM used to find O&M Labor ($ Million) 496.5 Productivity* 8.7 *Workers per $Million in Payroll for Electricity Generating Sector, Forecast to 2015 Sources: Productivity from 2007 Economic Census and Growth Rate from BLS. Labor requirement to operate the controls is estimated for all equipment types combined, using the incremental FOM costs from IPM. The IPM incremental FOM cost estimate included capital costs for fabric filters and scrubber improvement costs, which were f irst subtracted to obtain the true FOM costs ($496.5 million). Resulting FOM cost estimate was then converted to labor needs using the workers/$ Million in total payroll for the Electric Generating Sector. **6A.3.2 Retirement Labor**  **Table 6A** **- 11: Inputs**  **to Labor from Retirements**

39 Fabric filters follow a different pattern. Instead of a resource usage estimate , we used the VOM cost for FFs and converted this to jobs using the workers per million dollars output for the relevant manufacturing industry sector.6A

Retirement labor was estimated by first identifying the retiring units from EPA’s modeling using IPM parsed outputs (using incremental retirements in the policy case). The next step involved estimating the capac ity of incremental retirements as well as the change in the FOM costs due to these retirements. Because of the discrepancies between partial retirements in EPA’s parsed outputs and System Summary Reports (SSR), FOM costs were scaled proportionately to ref lect the lower SSR
- based estimates, as shown in Table 6A
- 11 above. FOM cost decreases were then converted to job
- years lost due to retirements using workers per $Million in payroll. **6A.3.3 Fuel Use Labor**  **Table 6A** **- 12: Inputs to Labor for Fuel Use**  **Coal by Region**  **2015 Incremental Fuel USE (Tons) 2008 Short Tons/Employee hour**  **Appalachia**

Total Production from 2009 EIA Annual Energy Review. Heat Contents from EIA, Heat Content of Natural Gas Consumed and 2009 Annual Energy Review. Employment Data from 2007 Economic Census. Fuel use related employment impacts were estimated by using IPM results for incremental changes in coal and natural gas use (policy case over the base case). For coal, estimates of coal use in tons by region from IPM were used in conjunction with labor productivity estimates from the EIA for each region (in short tons/ employee hour), to calculate the change in job
- hours needed. These we re then converted to job
- years, assuming 2,080 working hours per year. As discussed above, because of the high variability in coal mining labor productivity in recent years, no attempt was made to forecast coal (and natural gas, for consistency) productiv ities, instead the most recent historical estimates were used in this appendix (which was the 2008 labor productivity for coal). For natural gas, the first step was estimating labor productivity since such information was not available directly from any reliable source. EIA production data from the Annual Energy Review for natural gas and crude oil (in TCF and barrels, respectively), along with EIA heat content estimates were used to find total crude oil and natural gas production in MMBtu for 2007. Lab or productivity in MMBtu per job
- year for the Oil and Gas Extraction sector was then estimated using data from the Census on oil and gas extraction employment. Then, the incremental natural gas demand from EPA’s IPM modeling results (in TCF) was converted to MMBtu of natural gas demand using EIA data on natural gas heat content. This was then used with the labor productivity estimated above to calculate the total job
- years needed for increased natural gas demand for the final MATS.6A
