( 1 ) Labor hours adjusted upwards to reflect revisions to the calculation requirements for completions and workovers with hydraulic fracturing (to

differentiate between completions and workovers with different well type combinations in each sub

- basin category). Based on 2012 subpart

W data reported to EPA as of September 1, 2013 , 40% of onshore production facilities re port completion/workover emissions; and 23% of

facilities with completions/workovers would have additional measurements. Assume 2 additional measurements per facility; and 8

engineering hrs / measurement. Hour increase = (40%) * (23%) * 2 * 8.

( 2 ) There ar e 12 1 new data elements, 8 revised data elements, and 16 deleted data elements for this industry segment. However, not all facilities

report data for each emission source. Therefore, based on 2012 subpart W data reported to EPA as of September 1, 2013 , th e average number

of data elements per facility is 6 0 new, 3 revised, and 1 2 deleted data elements. Labor hours adjusted by 3 minutes per data element to

account for the new, revised, and deleted data elements.
