 a) BLS, 2013, US Bureau of Labor Statistics, May 2012 National Occupational Employment Statistics data. March 23, 2013. Occupations are the same as those used in the previous ICR. The employment categories used are from the Standard Occupational Classification system (SOC).
 b) EPA calculated the loaded hourly wage rate by inflating the raw hourly wage rate by 54 percent to account for benefits and overhead (EPA, 1992). This is the same percentage estimate for benefits and overhead as used in prior ICR supporting statements.
 c) This is the mean hourly wage for the "Construction and Extraction Occupations (Major Group)" category, SOC 47-0000, in BLS, 2013. 
 d) This is the mean hourly wage for the "First-Line Supervisors/Managers of Construction Trades and Extraction Workers" category, SOC 49-1011, in BLS, 2013.  
 e) This is the mean hourly wage for the "Secretaries, Except Legal, Medical and Executive" category, SOC 43-6014, in BLS, 2013.  
 f) This is the mean hourly wage for the "Automotive Service Technicians and Mechanics" category, SOC 49-3023, in BLS, 2013.
 g) This is the mean hourly wage for the "First-Line Supervisors/Managers of Mechanics, Installers, and Repairers" category, SOC 49-1011, in BLS, 2013. 
 h) Because there is no industrial hygienist category in BLS, 2013, the mean hourly wage for the "Health and Safety Engineers, Except Mining Safety Engineers and Inspectors" category SOC17-2111, in BLS, 2013 was used. This category was used based on the similarity of duties as described in the data.
