ENVIRONMENT, INC. PAGE 2 L.G. EVERIST, INC.-WEST FARM RESERVOIR ADEQUACY RESPONSE 01 MAY 23, 2023 found that the notes on the C map did not match what was on the map so it was moved to the Exhibit C-1 Mining Plan Map. 2) Information for structures within the permit and within 200'of the permit as listed on Exhibit C-1 Mining Plan Map should be identified on the provided Exhibit C-2 Structures Map. All structures listed should be identified on this map so that they may be correlated to the correct structure owner. The structure information list on Map Exhibit C-1 -Mining Plan Map was moved to Map Exhibit C-2. This structures list has key letters added to each owner that corresponds to the location of the structure and their owners marked on the map. 3) The surface drainage corridor which conveys irrigation return flows from the adjacent property to the south, back to the South Platte River, as observed during the pre-operational inspection, has not been shown on the existing conditions map - Please revise as needed. I have hatched and labeled the return flow drainages so they are easily identified on the Map Exhibit C. 4) No description of existing vegetation has been provided as required by (e). I added the vegetation information Exhibit J to Map Exhibit C. 5) Please show the location of the 50 acre Plant Site as described on the Mining Plan Map, including the location of the gravel washing/processing area, concrete batch plant, asphalt plant and recycling facility. Sufficient detail will need to be provided for these facilities so that an accurate bond for removal and reclamation can be calculated. The 50 acre Plant Site envelope is show as the \\\ hatched area in Phase 4 on Map Exhibit C-1. L.G. Everist does not have a specific Plant Site Layout at this time, and it is unreasonable to require this as it hinders LGE's flexibility to operate the mine if they have to file a change of plans every time they make an operations change. to the Plant Site area that is already designated in Phase 4 on Map Exhibit C-1 is where the various processing plants and stockpile areas will be located. For bonding purposes, the gravel processing plant, scales, asphalt and concrete plants will be portable equipment and would be removed if the mine failed. We have included a cost to remove an estimated 300 cu-yds of concrete foundations from the Plant Site to cover the temporary foundations for the listed equipment. When mining is scheduled to begin, this will increase to 500 cubic yards to cover all foundations, including the conveyor crossing and runs as Shown on Table L4 in the cost estimate.
