Mr. Brock Bowles -3- December 6, 2016 Hole", and is apparently located within the ditch recently dug by Mr. Fontanari. A second is labeled "Air Shaft", which is located east of the feature labeled "Sink Hole" on Appendix J. A third is labeled "Rock Pile", and appears to be located directly south and a bit to the east of the feature labeled on Appendix J as the "Air Shaft". Please confirm whether the "Air Shaft" identified on Figure 14-17 of TR69 is the same feature as the "Air Shaft" identified in Appendix J of Mr. Beckwith's comments (we believe it is). Please also confirm whether the "Rock Pile/Sinkhole Surface Expression" identified on 14-17 of TR69 is the same feature identified as the "Rock Pile" on Appendix J of Mr. Beckwith's comments (we believe it is not). SCC: The yellow and red symbols on the Fugro April 18, 2016 Figure 2, labeled "Air Shaft Location per Snowcap" and "Sinkhole/Surface Expressions", respectively are the same two features identified on Figure 14-17 as "Air Shaft" and "Rock Pile/Sinkhole Surface Expression". All features labeled on the "Fontanari Appendix J" provided by Mr. Beckwith are incorrect. The "Air Shaft" identified in the "Fontanari Appendix J" is the "Rock Pile/Sinkhole Surface Expression" identified on Figure 14-17. The "Fontanari Appendix J" does not denote the "Air Shaft" in the correct location. The "Rock Pile", as labeled on "Fontanari Appendix J", is just that, a pile of rocks and not a feature included in Snowcap's investigation. 2. DRMS: It is stated on "Page 3 of 7" of the August 23, 2016 report by Fugro to HBET that "Per a mine representative, approximately 10,500 gallons of water was poured into depressions within the ground. This was done to increase the electrical conductivity of groundwater pathways and increase their detectability by the electrical survey. Approximately 8,500 gallons were poured into the main depressions (sinkholes) within the trench where it turns to the west. Another 2,000 gallons went into the rock pile feature below". "Below" refers to Figure 3 on "Page 3 of 7". Figure 3 is a photograph with a caption that reads "Figure 3 shows a backfilled sinkhole immediately west of the buried 8 inch non-metallic water line. A metal marker post for the water line can be seen in the upper left side of the photo". Please confirm whether the feature shown as Figure 3 is the same feature labeled on Figure 14-17 of TR69 as "Rock Pile/Sinkhole Surface Expression" (we believe it is). SCC: Figure 3 of the Fugro August 23, 2016, report is the same feature labeled on Figure 14-17 of TR69 as "Rock Pile/Sinkhole Surface Expression". 3. DRMS: On page 2 of his October 2016 comments, Mr. Beckwith states that "In the interm, the Fontanari Plan calls for repair and improvements of the Martin Crawford Ditch: damaged by subsidence from Snowcap's mines." Please reply as to whether this ditch is presently included in the permit for the Roadside inventory of structures required under Rule 2.05.6(6)(a), and if so, what steps Snowcap should take per Rule 2.05.6(6)(f)(iv)(A). SCC: Portions of the Martin Crawford Ditch are located within the permit boundary. SCC does not know if the repair and improvements noted by Mr. Beckwith are referring to the portions of the Martin Crawford Ditch located within the permit boundary. The inventory of structures beginning on approved permit page 20-1 calls out the ditches that were reestablished in 1992. Steps Snowcap would take per Rule 2.05.6(6)(f)(iv)(A) are discussed on approved permit pages 20-7 and 20-8. 4. DRMS: On page 11 of his October 2016 comments, Mr. Beckwith states that "Both Fontanari and Carey hold extraction permits from DRMS and Mesa County ... to extract basaltic minerals from their respective properties. To illustrate the deposits to PsCO, Fontanari dug two test pits, each 25+ feet in depth". We understand that one of these pits is identified in Figure 14-17 as "vertical shaft in Carey Pond". If the other test pit lies within the limits of Figure 14-17, please identify its location on Figure 14-17.
