Received <br />.~ <br />REPORT ON CURRENT SITE CONDITIONS <br />Sunday Mine, Permit M-1977-285. <br />~E8 t; 7 ?-003 <br />afvls~ c ~ ~~Id WJreQ °9Y <br />The Sunday Mine is one of five permitted mines and related facilities held by the <br />Operator in the Big Gypsum Valley of San Miguel County, Colorado (see Figure 1, General <br />Location Map). <br />The Sunday Mine Pennit includes the Sunday Mine site, the GMG Mine site, and a <br />number of vent holes and related access roads located on the ridge to the south of the Sunday <br />Mine site. Figure 2, "Sunday Mine, Roads and Vent Holes," shows the location of the vent holes <br />and roads in relationship to the Sunday Mine site. Figure 3, "Sunday Mine," shows the site <br />details at the Sunday Mine site, and Figure 4, "GMG Mine," shows the details at the GMG Mine <br />site. <br />Roads and Vent Holes. <br />Figure 2 shows the location of all of the vent holes, and associated access roads, included <br />under the Sunday Mine Permit. Figure 2 also shows the location of a number of PreLaw vent <br />holes. All vent sites are described hereunder. <br />S-1 Vent -This vent is the westernmost of a cluster of three vent holes located just to the <br />east of the existing main access road up the ridge. A short access road connects this vent to the <br />existing main road; the access road was rough and difficult to traverse, so the Operator graded <br />the access road and installed water bars in November 2002. S-1 is an uncased 7' diameter up- <br />reamed hole. The vent has a fan on it and is grated and secure. A nearby power pole has three <br />transformers on it, and the transformers and the powerline to this site are the property of the <br />Operator. The site is generally stable, but soft, green clay from the cutbank on the uphill side of <br />the location is eroding onto the leveled site. This is not noted as a particular concern, as the soft <br />clays throughout the project area erode similarly under natural conditions. There is some sparse <br />weedy vegetation on the site. <br />S-2 Vent -This vent is located at the south edge of the Sunday Mine yard. This is a 7' <br />diameter hole that is covered by a steel grate welded in place. There is no fan on this hole as it <br />exhausts by natural upcast flow. Double power poles are located nearby, but no transformers are <br />present. The vent hole is surrounded by a gravel pad, and a lot of native brushy vegetation has <br />moved onto this site. There is no separate access road associated with S-2. <br />S-3 Vent -Vent S-3 is located on the crest of the main ridge above the Sunday Mine. <br />Access to S-3 is on a road dedicated to this site, the S-5 vent hole, and previously to the radio <br />tower that was located at the high point of the ridge. S-3 is an up-reamed 8' diameter hole on a <br />flat site excavated in maroon shale and siltstone. The location is very stable with no sloughing or <br />caving around the vent and no erosion from the site. The hole is covered with a fan and has a <br />grate welded in place. Three transformers are mounted on a nearby power pole, and the <br />powerline and transformers are the property of the Operator. There is no natural revegetation <br />occurring on this site. <br />
