Labor Wage Formulas

For this ICR, the Agency revised the estimated wages, benefits

, and overhead for all

labor categories for affected industr y and EPA employees based on the most recent publicly

available data from the US Bureau of Labor Statistics. T he methodology for calculating the

wage rates is the same for both the emergency exemption and SLN collections, and are based on

201 4 wage data. The calculation of the wage rates uses base wage dat a for each sector and labor

type for an Unloaded wage rate (hourly wage rate) and calculates the Loaded wage rate

(unloaded wage rate + benefits) and the Fully loaded wage rate (loaded wage rate + overhead)

based on that data

. Fully loaded wage rates are used to calculate respondent costs.

Unloaded Wage Rate: Wages are estimated for labor types (management, technical, and

clerical) within applicable sectors. The Agency uses average wage data for the relevant sectors

available in the National Industry

- Specific Occupational Employment and Wage Estimates from

the Bureau of Labor Statistics (BLS) (see http://www.bls.gov/oes/current/oes_nat.htm )

.

Sectors: The specific North American Industry Classification System (NAICS) code and

website for each sector is included in that sector’s wage rate table

. Within each sector, the wage

data are provided by Standard Occupational Classification (SOC). The SOC syste m is used by

Federal statistical agencies to classify workers into occupational categories for the purpose of

collecting, calculating, or disseminating data (see http://www.bls.gov/oes/current/oes _stru.htm ).

Loaded Wage Rate : Unless stated otherwise, all benefits represent 4 4 % of unloaded wage

rates, based on average rate of benefits for all civilian non

- farm workers (see

http://www.b ls.gov/news.release/ecec.t01.htm )

. I f any sectors are listed for which 4 4 % is not

applicable; the applicable percentage will be stated.

Fully Loaded Wage Rate: The l oaded wage rate is multiplied by 50% (EPA guidelines

suggest 20

- 70%) to get overhead co sts.
