The pond embankment was well vegetated and appeared to be stable and no erosional problems were noted. -The diversion ditch for the refuse pile is being used as a road around the pile on the south side of the pile.

There is a large amount of sediment in the ditch from"Y"to the Newlin Creek Mine all the way down to the culvert that runs under the road into Pond 5. This ditch will need to be cleaned. The culvert under the road was clean at the time of the inspection. -The two loadout sediment ponds were dry at the time of the inspection. Both pond embankments were well vegetated and stable and no erosional problems were noted.

The majority of the site(with the exception of the older lifts of the refuse pile)was seeded in 2002 and is in the eighth growing season. There has been some rubber rabbitbrush that has volunteered in on the facilities area and the reclaimed Pond 3 area. Some of the live transplants are still surviving and there are also some volunteer piiion and juniper trees on the site. Overall the site is doing very well. SIGNS AND MARKERS—Rule 4.02: -The mine ID sign is located along the main entrance road after the locked gate. Although the sign contained all of the required information, Southfield should consider either moving this sign or installing a second sign at the locked gate to better identify the site. Both sides of the loadout in Florence had mine ID signs. Number of Partial Inspection this Fiscal Year: 3 Number of Complete Inspections this Fiscal Year: 1 Page 3 of 6
