	1 Historic records indicate that 7,516 NPDES permittees particpate in the DMR-QA program. Most participate in the Chemistry/Microbiology component. Though a smaller amount also participate in WET analysis, it is unknown how many of permittees actually participate in WET analysis. It is estimated that 4.77% of all labs participate in the WET analysis.											Ave. Labor plus Non-Labor Cost Per Respondent:	$332

		*based on set-up, maintenance, data crunching at conclusion, 10 hr (chronic) also includes daily weighting
					because only 4.77% of labs do WET analyses, the following number will be used for time burden for WET tests:
					2.4	hours for WET analysis
