increase in the discharge from Outfall 016. On June 19"', the metered flow increased to 282.6 gpm <br />and peaked at 305. 8 gpm. The last metered reading on August I Id, was 303.1 gpm. Since this level <br />of flow has been recorded in the past, there is no direct correlation between the water application at <br />the surface and the increased flow seen at Outfall 016 over the period from June - July, 2014. Further <br />investigation will be needed to determine the correlation (if any) between water applied at the surface <br />above the mine and outflow from Outfall 016. The flow from Outfall 016 has been fairly consistent <br />since its inception on March 31, 2002. There is no evidence of any subsidence cracks visible at the <br />surface in the vicinity of the Carey Pond or on the Fontanari property in this locale where Mr. <br />Fontanari could purportedly irrigate the land. However, during the June 11, 2014 inspection of Mr. <br />Fontanari's property, we viewed several features that Mr. Fontanari indicated he believed were <br />subsidence related. One location on the Fontanari property appears to be a reclaimed vent shaft that <br />shows signs of erosion and slumping. It is important to note that the land Mr. Fontanari has tried to <br />irrigate in the past belongs to Jason Carey which is adjacent to the Fontanari property. This parcel of <br />land is not part of the SL -8 bond release application. <br />During the June 11, 2014 inspection, Mr. Fontanari went on to describe several other matters related <br />to former mine operators that date back to the early 1980s. Mr. Fontanari added that if someday he <br />farms or mines (gravel) on the land above the mine, he does not want to be responsible for any <br />hydrology problems that might arise. Mr. Fontanari indicated that he believes the Division should <br />deny bond release (or at least some portion of it) based on possible future hydrologic problems. The <br />June, 2014 inspection concluded at this point. <br />Mr. Fontanari attended the first day (October 23, 2013) of the October 23-25, 2013 SL -8 bond release <br />inspection to again voice his objections regarding the bond release application. Mr. Fontanari raised <br />two new concerns located within his property boundary during the inspection as follows. 1) He lead <br />the inspection group out to the edge of a rock outcrop located on his property that overlooks Interstate <br />70 (see Photograph No. 32). This was the approximate location of a rock fall event that occurred in <br />September 2013 temporarily impacting I-70. He stated that he believes the rock fall occurred as a <br />result of subsidence from the underground mining operation. 2) Later that afternoon, Mr. Fontanari <br />lead the group to another location en route to the 2 West Portals area. At this location, he stated that <br />there are subsidence cracks up on the hillside to the east of the location of the old "Go Boy Mine". <br />The location was a substantial climb up the west facing slope of the mountainside (see Photograph <br />No. 33). Several of the participants inspected the location and climbed up to the reported subsidence <br />cracks. The cracks that were inspected do appear to be subsidence related. The lower of the two <br />cracks that were inspected is shown in Photograph No. 34 and the upper area where cracks are present <br />is shown in Photograph No. 35. Mr. Fontanari alleged during the inspection that subsidence features <br />have been apparent on the surface and continue to develop periodically. These cracks described here <br />are the only cracks identified during the SL -8 bond release inspection and during previous inspections <br />throughout the entire mine site and adjacent affected areas. Because most subsidence occurs shortly <br />after mining is complete and the remaining residual subsidence occurs within two to three years after <br />mining, it is unlikely that additional subsidence cracks or features will develop. These subsidence <br />cracks, shown in the attached photographs, are located approximately in the SWI/4 of Section 1, <br />Township 11 S, Range 98 W, very close to the boundary between the old Go Boy Mine and the <br />Roadside South Portals Mine. Mr. Fontanari stated that he believes the subsidence cracks that have <br />formed are likely affecting the quantity of water he diverts for irrigation purposes. The lower and <br />upper subsidence cracks are located up the steep hillside approximately 300 feet gain in elevation <br />Page 25 <br />
