I think the arc they refer to is part of the approach procedure. The arc's center is a DME, usually co-located at a VOR and the distance out to the arc is on the order of 10 - 15 miles. The pilot intercepts the arc and follows it to where it intercepts the final approach course and then turns onto the final course.

This type of approach is not common. It may be used here to keep the entire approach closer to Groom and avoid going to far out into the Nellis Range. The link shows a typical ILS with arcs at Amarillo. Sure would love to see the one at Groom!
