(Page 3) • • MINE ID # OR PROSPECTING ID # M-96-049 INSPECTION DATE 09/27/00 INSPECTOR'S INITIALS ESC It is clear the L.G. Everist has approval to dispose of inert material in the pits/ponds from Summit County and the Division. However, the notice sent to the Division on May 20, 1999 is vague regarding the source of the material, the County sign-off procedure, the change in the volume of material and the contents of the inert material. In addition, the notice does not state that concrete material will be placed in the pit (either as a slurry or hard). The operator should be reminded that concrete is considered inert material that has been in a hardened state for at least sixty days. In order to clarify the notice with the Division regarding backfilling using inert material, the following information must be submitted by November 6, 2000; • Specify the nature of the inert material. • Explain the Summit County's role regarding the signed affidavit certifying that the material is clean and inert. • Clarify how the operator verifies on site that material is clean and inert, and that wood and wood products are not backfilled into the pit/pond. • L.G. Everist will need to ensure that any concrete disposed in the pit/pond must be in a hardened state for at least sixty days. Please describe the handling and dumping procedures to ensure this requirement is met. • Please verify to the Division that the groundwater has not been impacted or polluted as a result of the material placed in the pit/pond on August 22, 2000. The operator will need to sample the pit/pond and an upstream location for pH and Electromagnetic Conductivity (EC). ~ ~ ~3~ ~g~ 335 I & H Contact Address ^ CE NAME Lvnn Maver ^ BL OPERATOR L.G.
