Summary of Changes for Final Burden

May 17, 2010

The following tables, from Part A of the Supporting Statement, have been updated 

to reflect the changes made to the burden estimate based on revisions to the ICR from the 

2nd FRN comment period. Please note that this summary only contains the tables from 

Part A of the Supporting Statement that changed from the 2nd FRN version. The changes 

are highlighted in red.

The estimated number of respondents changed based on finalizing the sample 

frame, changing the cutoff date for the Parts C, D, and F cost sections to 2000, and 

adjusting to the estimated number of sample points for Part G. The change to the cost 

section cutoff date accounted for changes in the number of respondents for Part C: 

Sections 2.3 through 2.5 and Sections 3.3 through 3.5; Part D: Section 6; and Part F: 

Section 3.2. The number of sample points changed based on reevaluating the assumptions 

used to calculate the burden. Previously, EPA estimated 204 sample points, which 

included all 51 sample points, multiplied by four to account for the four weeks of 

sampling; however, the hourly estimate was revised to account for all four weeks of 

sampling at one sample point, and then multiplying by the 51 sample points. 

The hourly burden estimates for each part of the questionnaire changed due to the 

revisions resulting from EPA/OMB review. The changes in Parts A and D resulted from 

dropping certain requests regarding the water balance diagram and analytical methods 

request for pilot studies, respectively. The hourly burden change for Part C resulted from 

the reorganization of the part; however, the total hourly burden for Part C did not change 

significantly, as a majority of the content did not change, just the organization. The total 

hourly burden for Part F increased as a result of the addition of the landfill cost section 

(Section 3.2). The burden for Part G Sample Collection changed due to public comment 

received during the 2nd FRN comment period. The resulting hourly estimate is a 

reasonable compromise between the hourly estimates previously reported and the 

estimates provided in public comment.

The hourly burden estimates for Parts B, E, and H did not change. No changes 

were made to Part B. Public comment expressed concern over the burden estimates for 

Parts E and H. EPA revised both sections and kept the hourly burden estimates the same, 

as the increase from public comment and the decrease due to revisions cancelled out.

The revised total hourly burden estimate is 123,146 hours. This is 21,306 hours 

less than the 2nd FRN burden estimate (144,451). The corresponding total dollar burden 

is $6,824,739. This is $1,187,159 less than the estimate for the 2nd FRN burden estimate 

($8,011,898). The total burden, including the capital costs, is $8,041,789. The average 

hourly burden for the 733 respondents is 168 hours.
