- 19 - Dividing 3,899,696 tons by 31.41 acres, we get 124,155 tons of sand and gravel per acre. Thus, a loss of 2 acres of land to setbacks will reduce the available volume by 248,310 tons. ii. Work Area The next factor reducing recoverable volume is the need for some land to be set aside for a workplant to sort the excavated material. We find credible the evidence that most plants are built on the property being mined. Terrene disagrees, arguing that we should not make any adjustments for a workplant because one might be set up next door on property that is still owned by Terrene or on the tract already given to the Foundation. We are unpersuaded. No evidence exists that shows Terrene ever contemplated such an offer during its talks with the Foundation, and we find that it would not be practical to have a plant on the previously donated parcel because it lies on the other side of a very busy Hamblen Road. A closer question is the size of the work area. The Commissioner urges us to find that roughly seven acres would be needed, while Terrene claims it would take only three. Voluminous testimony on this exact point convinces us that four acres would suffice. Local operators Enloe and Vestal credibly testified that, in their experience, operators on plots the size of the Hamblen Road property usually used about three-to-four acres to set up their work area.
