III. COMMENTS -COMPLIANCE <br />Below are comments on the inspection. The comments include discussion of observations made <br />during the inspection. Comments also describe any enforcement actions taken during the inspection <br />and the facts or evidence supporting the enforcement action. <br />This partial inspection of the New Horizon Mine focused on repairs to drainage structures completed <br />by Western Fuels following an intense thunderstorm event on July 10~". During the inspection, DBMS <br />inspector was introduced to Mr. Ward Burbridge, a landowner for portions of the permit area, who <br />commented on "sink holes" and areas of inconsistent alfalfa production for reclaimed lands. Ten <br />photos accompany this report. <br />Mining and reclamation activities were active. Repairs to sediment containment ditch C11 and C17 <br />appeared to have been completed. Evidence of seeding to the recently repaired areas was observed <br />at ditch C17. Ditch C11 was conveying pit drainage to sediment pond 8. An erosion resistant drop <br />structure, constructed of large angular rock and half-sections of corrugated metal pipe, had been <br />installed at the inlet to pond 8. Drainage to pond 8 was retained, no discharge from pond 8 was <br />occurring. The drainage containment berm and ditch for the SAE located west of pond 7 had also <br />been repaired. Straw bale sediment filter was intact at the outlet for the SAE. Evidence of affected <br />area drainage escaping the permit area without treatment was not observed. <br />As noted by Mr. Burbridge, some portions of the reclaimed alfalfa field appeared to be less productive <br />than other portions. Low yield areas were easily identified by the thin alfalfa windrows. Some of the <br />low-yield areas appeared to be locations where drainage could concentrate but not all low-yield areas <br />appeared to be drainage related. The operator indicated that they were aware of the variability in <br />production and were attempting to determine the cause. <br />A shallow depression in the reclamation area was located adjacent to an irrigation supply line. The <br />depression was approximately 30 feet diameter and 1 foot deep. Cattails were well established within <br />the settled area, soils were wet and muddy. The settling appeared to have occurred previously but not <br />active at this time. No tension cracks or other evidence of active settling were located. The operator <br />indicated that the minor subsidence feature could be backfilled to ensure positive drainage. No other <br />subsidence features were identified. <br />
