My answer is that the Service Contract Labors Statute does not apply to a rental of equipment. (rationale: What labor categories would you apply the SCLS to in the this instance?)

The fact that a government employee operates the equipment on Government time as part of their duties does not impact his or her pay as a wage grade employee. Thus, the SCLS is not applicable to the equipment rental or Government employee operating the equipment.

Suggest that you contact your legal counsel or Department of Labor if you have further questions on the above scenario.
