' 2. Duration of Operation : The volume of gravel required by a paving company <br /> is obviously dependent upon the amount of paving done by that company. <br /> This , in turn , is dependent upon the amount of land development in' a given <br /> ' area and upon the amount of re-paving done by counties and municipalities. <br /> Following is a list of assumptions made in order to estimate the duration <br /> ' of the proposed operation : <br /> ' a. Longest Duration <br /> (l .) No gravel sold as raw aggregate to competitors. <br /> ' (2.) No growth in demand for paving in the area. <br /> (3. ) Aggregate used for both base course and asphaltic concrete. <br /> ' (4.) Aggregate not used for portland cement concrete. <br /> b. Intermediate Duration <br /> (1 .) No gravel sold as raw aggregate to competitors. <br /> ' (2.) Five percent annual growth in demand for paving in the area. <br /> (3.) Aggregate used for both base course and asphaltic concrete. <br /> ' (4.) Aggregate not used for portland cement concrete. <br /> c. Shortest Duration <br /> 0 .) Gravel sold as raw aggregate in significant quantities (this <br /> ' event is considered improbable) . <br /> (2.) Zero to five percent annual growth in demand for paving in the area. <br /> ' (3. ) Aggregate used for both base course and asphaltic concrete. <br /> (4.) Aggregate not used for portland cement concrete. <br /> Based upon the assumptions stated above, and applying historic pro- <br /> tduction rates , it appears that the longest duration of the proposed <br /> mining operation would be 26 years. The assumption of no growth in <br /> demand for paving is considered to have a low probability of occur- <br /> rence. It is considered much more highly probable that the assumptions <br /> ' -12- <br />
