COMPLIANCE WITH INTERIh1 REGULATIOIJS
717.11 General Obli ate ions
Grand Mesa Coal Company had applied to the State MLR Division for a
conversion of their 110 permit to a 112 permit. This conversion was
approved at the June MLR Board meeting. The bond has not yet been
posted. The 112 permit includes 53 acres at the minesite. This
permit conversion approval constitutes an approval of the mine plan
which includes the surface runoff control plan. OSM NOV 80-5-18-9,
issued on February 7, 1980, gives an abatement period of 90 days from
the time of plan approval for the runoff control plan. Therefore, the
abatement date is September 24, 1980.
717.14 Backfilling and Grading
and
717.15 Disposal of Excess Rock and Earth
MSHA pernrit N1211-CO-9-0021 applies to the refuse disposal in the old
pit within the permit area. In a February 1980 letter to MSHA, the
operator states that disposals are being made in two foot compacted
lifts, and that final grades will not exceed a 10:1 slope. Refuse was
being hauled to the pits during this inspection. No grading was taking
place.
Chemical analyses of refuse material from the mine, and overburden and
topsoil from the minesite were made by CSU laboratories. Results were
available in May 1980. These analyses will be utilized when filtration
and toxicity tests are conducted on the pit backfill material as part
of the groundwater monitoring program.
717.17 Protection of the Hydrologic System
NP DES permit ,YCO-0036935 expires on September 30, 1984. The one dis-
charge point is located at the sediment pond planned for construction
on an unnamed tributary of a manmade irrigation ditch, Carbon Ditch.
