Reason for Report:  OTHER     Cause of Condition:  OTHER     Potential Receptors:  POSSIBLE SEASONAL POND ADJACENT TO THE NE, 1 PERMITTED WELL #235207, ADJACENT PROPERTY N.
  
INITIAL ACTION:   AERIAL PHOTO 1 ILLUSTRATES APPROXIMATE DISTRIBUTION OF INITIAL STOCKPILES AND PHOTO 2 SHOWS APPROXIMATE DISTRIBUTION AS OF 11/21 AFTER MATERIAL WAS SPREAD OVER PROPERTY.
  
SOURCE REMOVED:   DRILLING MUDS WILL BE MIXED AND TILLED IN WITH THE EXISTING TOP SOILS. AS OF 11/21, THE INITIAL SPREADING OF THE MATERIAL OVER THE AREA TO BE TREATED HAD BEEN ACCOMPLISHED. THE INITIAL TILLING OF THE MATERIALS WAS IN PROGRESS.
  
HOW REMEDIATE:   ADDITIONAL TILLING AND MIXING WITH THE TOP SOILS WILL CONTINUE UNTIL THOROUGHLY MIXED. ACTIVITY WILL PROCEED WEATHER PERMITTING. THE GROUND SURFACE REPORTEDLY HAS STARTED TO FREEZE WHICH HAS CURRENTLY LIMITED THE ABILITY TO PENETRATE THROUGH THE SURFACE. IT IS ANTICIPATED THAT THIS TOP SOIL AUGMENTATION WILL IMPROVE THE MOISTURE RETENTION CAPACITY OF THE SOILS AND THEREBY PROMOTE VEGETATION GROWTH. A SEDIMENT BERM OR SEDIMENT FENCING WILL BE PLACED ALONG THE DOWNGRADIENT SIDE OF THE TREATMENT AREA (NW SIDE) TO PROTECT THE TOPOGRAPHIC LOW AREA ADJACENT TO THE SITE.
  
MONITORING PLAN:   GROUND WATER IMPACT HAS NOT BEEN DETERMINED. GROUND WATER IMPACT NOT CONSIDERED LIKELY BASED ON THE TYPE OF MATERIALS PLACED ON THE SITE AND THE DEPTH TO GROUND WATER.
  
5-RECLAMATION PLAN:   DRILLING MUD AND ASSOCIATED LIQUIDS WILL BE MIXED AND TILLED INTO THE SURFACE TOPSOIL MATERIALS. THE SITE WILL BE GRADED AND CONTOURED TO MATCH WITH THE LOCAL LANDSCAPE. THE INITIAL SUCCESS OF THE PROGRAM WILL BE EVALUATED IN THE SPRING/SUMMER OF 2012. IF NECESSARY, RESEEDING MAY OCCUR.
