Letter, 24 June 2019 M2013-066 Loblolly Pit Page 2 Exhibit G —Water Information During mining: Initially, in the South Parcel, the pit was dewatered and water pumped back into the river, but this has not been done in the North Parcel. All dewatering and discharge of water into Waters of the State has ceased and there is no plan to again do so. There is presently no surface discharge of water from affected areas of the site, and there is adequate storage capacity in the ponds/basins to accept runoff from adjacent, unaffected land without any surface discharge for at least a 100-year, 24-hour storm event. During reclamation and post-reclamation: The water level in the ponds on both parcels will rise and fall with the water flow in the river, and there will therefore be an area around each pond in which changing water levels may result in both quantities and species of grass and forbs which flourish best, and in which willows and other water-tolerant species will naturally become established. Exhibit J Vegetation (including Seed Mix) The seed mixes in Exhibit J, Item 3 currently remain unchanged. This additional information is provided as requested: Seed mix #1 (temporary) will continue to be used to stabilize soil stockpiles and other areas in order to prevent/mitigate wind and water erosion, protect soil and other purposes, including the 4.6 acre areas which are industrial sites. Seed mix#2 (irrigated/semi-irrigated) will be used adjacent to the ponds and in general, east of the pipeline which divides both parcels. The initial seeding of the South Parcel areas now at final grade with soil (12.7 acres of the large area around the ponds), uses the irrigated/semi- irrigated mix. Seed mix #3 (grazing) will be used generally west of the pipeline and in areas higher in elevation than the immediate vicinity of the ponds, and adjacent to the permanent roads. If done while this permit is still active, any reclamation of the well pads in both parcels will be done in accordance with COGCC requirements in affect at the time of reclamation of those pads and the associated disturbed areas. The reclamation plan continues to assume that the roads to these pads will be permanent, as access to the reclaimed well pads will still be necessary. I The exact locations for use of the various seed mixes cannot be accurately determined until final reclamation and upon advice (and site visits) from NRCS/Conservation District gurus to examine soil and moisture conditions. We also need to keep in mind that NRCS may change recommendations as to the best seed mixes. Therefore, the TR again emphasizes that the seed mix used at the time of final reclamation may change based on NRCS/NRCD recommendations to the landowner. Exhibit L Reclamation Cost Estimate As regarding reclamation and cost estimating of the performance warranty: 1. Although the surface has been disturbed west of the Pipeline in both the North and South Parcels, there has been no actual excavation of materials in those areas yet. That mining, when done in the future, will require again estimating cost of reclamation at that time. 2. Since the 2019 Annual Report and the 2019 Inspection, the stockpiles and the berm along the road near the bridge (in the South Parcel) have been removed. (The new 2019 Annual Report maps show the status as of April-May of 2019 and your visit.) 3. The South Parcel is zoned industrial, and in addition to the three areas identified as industrial sites at present, there would certainly be others in the future. However, for purposes of reclamation cost estimates, it is reasonable to assume for now that all of those would have topsoil replaced and be seeded to grass. 4. As part of the TR, it is important to again note that the South Parcel may be hosting various temporary or permanent industrial plants/activities (including but not limited to ready-mixed concrete plants, hot-mix asphalt facilities, sawmills, grinding and shredding, and other
