Recent questions have been raised about the amount of topsoil available for reclamation of the Gloria Z Mine since the disturbed area has expanded and there is evidence that the excavation of a perimeter ditch did not have adequate topsoil removal. I conducted an inspection on October 1,2014 with a handheld Garmin GPS which reported an accuracy of 11-16 feet on site. Over 200 points were taken of the perimeter of the topsoil stockpiles as well as the perimeter of the disturbance. These points were later transferred to the registered cad map in the State Plane coordinate system and were found to be sufficiently accurate to make topsoil quantity estimates. The attached table was developed by me to evaluate the topsoil amounts in each of 6 areas. The areas were measured in cad after adding the gps points. The heights of the piles were measured with a tape and the average heights were estimated. There are 5 stockpile locations on site and one area that has not yet been stripped (Area 3). This area was spot checked with a track hoe excavator during the site visit and found to have an approximate average depth of soil of 1.8 feet. The attached map shows all 6 topsoil areas and the footprint acreage of each. The revised disturbed area to be re-topsoiled has been calculated from the gps points for the edge of the disturbance and was found to be 37.12 acres. Since 1.55 acres of this area will be left as roads, the total area for re-topsoiling is then 35.57 acres. At the approved depth of 6 inches, this requires a topsoil quantity of 28693 cy. The attached table shows that 34207 cy is available, therefore,there is a surplus of 5514 cy.
