Lorencito Canyon Mine,C-1996-084 <br /> April 11,2022 <br /> Page 2 of 2 <br /> DRMS: This item is unresolved. MW-5 being located within proposed workings has not yet been <br /> addressed. Without the additional data requested in item No. 1,it is difficult to assess the adequacy <br /> of the location as an upgradient well for the P1 area.An upgradient well for P2 has not yet been <br /> addressed. This information can be provided and reviewed with PR application. <br /> 3. The anticipated screening intervals for each of the nests of bedrock wells should be provided. <br /> Response: The existing wells and screening intervals are included in the well logs in the attached exhibit <br /> (Exhibit 7) that we have included in this response. <br /> DRMS: The existing well logs have been provided. However the request was for the anticipated <br /> screening intervals for the proposed nested wells. This information is useful to assess the layers the <br /> operator plans to monitor. It is understood that the exact intervals may differ upon well completion <br /> but from a planning and adequacy standpoint it would be useful for the Division to verify that the <br /> well screens will be within the geologic layers that the Division will require monitoring.This <br /> information can be provided with the PR application. <br /> 4. Table 1 lists the Surface and Groundwater Monitoring Stations. The purpose column within this table should <br /> be reviewed by the operator for accuracy.For example; WMLPC-1,WMLPC-2, and WMCC-1 are all listed <br /> to be upgradient monitoring points in Little Pine Canyon, which does not appear accurate from the map <br /> provided. <br /> Response: The table has been updated to reflect what is illustrated on Map I of the Proposed Hydrology <br /> Monitoring Plan. <br /> DRMS: Table 1 appears to be updated. <br /> 5. If coal from the P1/P2 Portal area are being transported and stored at to the raw coal loadout shown on the <br /> map. Surface water monitoring may be appropriate at the loadout prior to the confluence with the Purgatoire <br /> River. <br /> Response: The coal loadout is not proposed to be constructed until a later date such as the second permit <br /> term.A Technical Revision Application will be submitted when this facility is proposed for operation. <br /> DRMS: Monitoring of the loadout can be determined at a future stage when the loadout <br /> construction is reviewed by the Division. <br /> 6. Subsidence monitoring of streams should be discussed within the revision application. <br /> Response:Subsidence monitoring ofstreams will be discussed in the PR Application to be submitted to the <br /> CDRMS within the next two weeks. <br /> DRMS: This information can be provided and reviewed with the PR application. <br />
