April 30, 2014 C- 1981 - 014 /Southfield Mine RDZ <br />ground when flow was initiated; the rest went down the well. <br />- Using markings on a hose connected to the tank, the flow into the well was continued until 1,500 gallons had <br />been poured into the well. Mr. Patterson showed the inspector the hose markings and his calculations of the <br />volume in the tank. These looked to be accurate. The volume of 1,500 gallons represents well over twice the <br />calculated volume in the well. <br />- Mr. Patterson determined that 1,500 gallons were pumped into the well in 12 minutes and 46 seconds. During <br />this time period, the water did not rise above the level of the well casing. <br />- By listening to sounds in the well, Mr. Patterson and the inspector determined that the water in the well <br />continued to flow past the obstruction and into the workings for 55 seconds after the flow from the truck tank was <br />discontinued. <br />This concluded the well test. Approximate flow through the well was over 100 gpm (1,500 gallons in less than 15 <br />minutes). <br />Pond 4 and Pond 5 were dry. Neither of these ponds was discharging. At the loadout, ponds L -1 and L -2 were dry <br />at the time of the inspection. No maj or problems were found with embankments, flumes, or spillways. The <br />following spillway pipes contain sediment (4 to 6 inches) and should be monitored: the emergency spillways at <br />Pond 4, the Pond 5 primary spillway, and the primary spillway for Pond L 1. <br />On the pond side of the embankment for Pond 5, there is a rill near the primary spillway that will need to be <br />repaired if it gets worse. <br />At the RDA, no problems were seen with diversion ditches or with the California Drain Pan at the northwest <br />corner of the RDA. <br />The portion of Newlin Creek where a landowner has indicated that there is a losing reach due to subsidence was <br />inspected for cracks or other indications of mining impacts. None were seen. The creek bottom soil was dry on <br />both sides of the markings of the area (the creek was walked for approximately 200 feet on both sides). <br />The inspector looked at the reservoir where the Town of Florence has constructed their intake from Newlin Creek. <br />The water was flowing into the town's intake pipe and was approximately three feet below the overflow pipe, <br />which allows the water to flow down Newlin Creek through the Southfield Mine. <br />PROCESSING WASTE /COAL MINE WASTE PILES — Rule 4.10 and 4.11 <br />Drainage Control; Surface Stabilization; Placement: <br />The perimeter of the RDA was driven; no rills or other problems were seen. <br />Number of Partial Inspection this Fiscal Year: 8 <br />Number of Complete Inspections this Fiscal Year: 4 <br />Page 3 of 8 <br />
