Subtracting an average of 2.5 feet of overburden and soil over an area of <br />7.78 acres results in a volume of 31,000 cubic yards. Additional subtractions for portions of the ex- <br />isting pond and the existing depression azea are approximately 20,000 cubic yards. Therefore, the <br />North Fork Ait Mazch 04 18 <br />
