The operator has proposed an expansion of the quarry from 30 to 65 permitted acres. The site ie located on the west end of Canon City and can be accessed from Tunnel Drive. The poet-mining land use is rangeland. 2. A number of concerns have .been expressed by the nearby residents of Tunnel Drive regarding the proposed expansion. The concerns of the residents will be .addressed through the public review process. An upcoming pre-hearing conference will be scheduled in Canon City. The date ie unknown at this time. We also anticipate a Formal Public Hearing before the Colorado Mine Land Reclamation Board. 3. The subject of surface blasting was discussed. Concerns have been expressed by the local residents regarding the impact of blasting on their homes. Mr. Klco suggested that a monitoring program be implemented to document the hours and intensity of I~lasts that occur at the quarry. The impact of blasts from the proposed amendment area ie expected to be lees than currently experienced because of the pit orientation. 4. The subject of dumping trash at the mine site was discussed. Concerns have been expressed by the local residents that Tezak Heavy Equipment Co., Inc. has been dumping and hauling trash illegally from the mine site. There was no evidence of traiah at the site at the time of inspection. A representative of T.H.E. stated that trash heed been collected previously on the Bite but outside of the permitted mine area. This conc~arn appears to be corrected. The Colorado Department of Health has also been notified of tliie issue. 5. The subject of excessive truck traffic on Tunnel Drive was discussed. This was also in response to concerns raised by local residents of Tunnel Drive. Recently, emergency conditions existed to highway and railroad structures along the Arkansas River. T.H.E. responded to these conditions by supplying riprap material from the quarr:f. Mr. Tezak had notified local authorities of hie plan to supply the needed materials and ae a result increase the frequency of truck traffic on Tunnel Drive. The local residents have also raised concerns of noise and duet from the truck traffic on Tunnel Drive. These concerns do not appear to be within the authority of the Division and will be addressed during the public review process. 6. The subject of fugitive duet control from the crusher plant was discussed. Hr. Klco indicated that an air emissions permit will be obtained from the Colorado Department of Health and that T.H.E. will voluntarily monitor fugitive duet levels to ensure compliance with standards set by the Health Department. 7. The subject of etormwater runoff control along the existing haul roz~d was discussed. Currently, there are no defined collection ditches along the road to control runoff. Sediments are washed offsite to the south onto Tunnel Drive and towa:cd the hydraulic irrigation ditch. Mr. Klco explained the components of the etormwater management plan which consist of 2 sedimentation ponds and runoff channels adjacent to the haul read. In addition, there will be a designed riprap structure near the outlet at Tunnel Drive to control runoff flowing toward the irrigation ditch. T.A.E. will monitor sediment levels in the irrigation ditch and will clean the ditch as necessary. 8. The entrance sign to the property did not contain the information required in Rule 3.1.12. Therefore, Mr. Rlco was advised to have the operator install an .adequate entrance sign. I 6 E Contact Address cc: Jim Stevens, CMG ^ CE
