(Page 2) MINE ID # OR PROSPECTING ID # M-1977-141 INSPECTION DATE 8/05/02 INSPECTOR'S INITIALS ESC OBSERVATIONS This was an inspection of the Lyons Quarry conducted by Erica Crosby of the Division of Minerals and Geology. Damian Murphy and Roy Hunt of Aggregate Industries were present during the inspection. The purpose of the inspection was to visit the area that will be amended into the permit area. The operator proposes to add 15 acres to the Quarry, for a total area of 69 acres. The addition of this land is to correct the disturbance conducted by the previous operator, Golden's Andesite Mining. The permit was transferred from Golden's to Aggregate Industries on June 4, 2002. The 15 acre addition will correct the problem associated with mining outside the permit boundary, and take into account all mining related disturbance associated with the site. The operator stated that a secondary amendment will be filed to revise the mining and reclamation plan and add additional acreage to the permit area. In particular, the operator is adding acreage to Area 4 located on the south end of the property. The area includes the south end of the highwall and a number of rock piles and overburden material created by Golden's prior to the transfer. The reclamation plan proposed by the operator is similar to the approved plan. Changes to the mining and reclamation plan will be filed under a separate amendment application. The Division's main concern regarding the contents in the permit application is the storage and location of topsoil. The previous operator pushed all topsoil and overburden material over the face of the Quarry with a dozer where mining was not anticipated. Large volumes of material exist on site, but the volume and location of such material is not adequately documented in the permit. It appears from the site inspection that enough material exists on site to achieve the required depth of 12" (on the original 27 acres) and 6"-12" (on the 1983 amended 27 acres). The practice of pushing topsoil over the edge of the quarry is not acceptable, and must be avoided by Aggregate Industries. The Division's adequacy questions were sent to the operator under separate correspondence. The Division's decision due date is September 9, 2002. There are currently no objections to the Amendment Application. I & E Contact Address ^ CE NAME Mr. Damian Murphy ^ BL OPERATOR Aggregate Industries- WCR, Inc. ^ FS STREET 3605 S.
