He also reported oak brush <br />surrounding the surface opening, <br />The vent is on Mountain Coal Company (MCC) property. Kathy Welt of MCC notified the Division on <br />March 11, 2017. <br />SLIDES and DAMAGE - Rule 4.12: <br />Tara Tafi and Jeff Litteral of the Division's Inactive Mines Program, together with a reclamation <br />contractor, visited the site on March 13 and observed four vents; three located in the oakbrush above the site, and <br />the fourth in the landslide debris. Notes from their inspection are copied below: <br />Vent 1: Fracture vent, located in the landslide debris. Surface temps ranged from 100-200 degrees F <br />Vent 2: Located above the landslide scarp. Venting steam with surface temps around 100 degrees. Three <br />small vents associated with this feature, total feature size is approximately 10' long along the fracture and <br />2' wide. <br />Vent 3: Large, newly formed vent upslope of vent 2, located in thick oakbrush. This feature appears to be <br />a mine feature, perhaps an old air shaft. The collapse is approximately 1 S' long by 10' wide. Inside of the <br />collapse is what appears to be shaft. I could not see the bottom of it. This feature is pushing a lot of steam <br />out of it. I measured temps around 200 degrees on the surface. The steam was hot, making it difficult to <br />see inside of the hole. The ground surrounding the feature was hollow, also making it difficult to get too <br />close. <br />Vent 4: located south and west of Vent 3. We did not visit this feature, but viewed it from below. <br />Number of Partial Inspection this Fiscal Year: 7 <br />Number of Complete Inspections this Fiscal Year: 3 <br />Page 2 of 12 <br />
