### 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

2 nd 

### FRN comment period . Please n ote that this summary only contains the tables from

Part A of the Supporting Statement that changed from the 2 nd 

### FRN version. The changes

are highlighted in red.

The estimated number of respondents changed based on f inaliz ing the sample

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

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

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

Sections 2.3 throu gh 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 estimate d 204 sample points , which

included all 51 samp le 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 f or 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, respect ively. 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 f or 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 2 nd 

### FRN comment period. The resulting hourly estimate is a

reasonable comp romise 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 estim ates for

Parts E and H. EPA revised both sections and kept the ho urly 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 21,30 6 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 $8,041,7 89

. The average

hour ly burden for the 733 respondents is 168 hours.
