Content of CDMG pond reports regulation yes 4.05.6(13 ) The monitoring plan on permit page 5-36 calls for sampling three wells semiannually for both field pazameters and full suite analysis. One of the three wells (94-1) was backfilled and reclaimed in 2002 during reclamation of the South Pit. The two remaining wells are located upgradient and downgradient of the mine. The sampling frequency for the upgradient well (17-1) was met in 2005. The downgradient well (95-i) was sampled in April 2005, but could not be found in December 2005, following reclamation of the Ewing gravel pit in which it is located. The omitted sample in December 2005 does not impair R. Sampling Page 5-36 the ability to assess hydrologic impacts due to the long-term frequency of of CDMG record from this well.

The Division has since issued a proposed decision to approve elimination of wells 17-1, 94-1, and 95-1 from the monitoring program (proposed in TR-13), based chiefly on a) historical monitoring data from the wells indicating no impacts from coal mining at Carbon Junction, b) recognition that any coal spoil leachate generated by and migrating from the relatively small (less than 10-acre) pit area at Carbon Junction would undergo significant attenuation and dispersion in the Animas River alluvium and Pictured Cliffs sandstone within a few hundred feet of the mine its.
