Alluvial Vallev Floor Determination
As stated in the meeting on June 15, 1983 between Terror Creek Company
and the Colorado Mined Land Reclamation Division ("Division"), Terror
Creek Company disagrees with the preliminary determination of the
Division that the loadout is situated on an alluvial valley floor
("AVF"). The term "alluvial valley floors", as defined in Section
1.04 (DEFINITIONS) of the Regulations of the Colorado tdined Land
Reclamation Board for Goal Mining, "means the unconsolidated
stream-laid deposits holding streams with water availability
sufficient for subirrigation or flood irrigation agricultural
activities...". Terror Creek Company has conducted a geological field
investigation of the site and concludes that the deposits beneath the
loadout are not "unconsolidated stream-laid deposits holding streams"
but rather colluvial "outwash" from the steep canyon walls of the
North Fork of the Gunnison River immediately north of the loadout
site; therefore, the area, based on the definition of AVF in the
Regulations of the Colorado Mined Land Reclamation Board for Coal
Mining, cannot be classified as an alluvial valley floor.
The field determination of the non-existence of an AVF was based on a
pre-disturbance geological investigation by Mr. Eldon St rid of ACZ
INC.; the results of his findings are shown on the Site-Specific
Geology hiap (Map 11) found in the Terror Creek Company submittal. The
results of Mr. Strid's site-specific field visit are confirmed by
regional mapping by the United States Geological Survey (see Regional
Geology/Hydrology Map (Map 2} of the Terror Creek Company submittal).
Since construction activities were initiated, Mr. Eldon Strid and Mr.
Alan Czarnowsky of ACZ INC. independently visited the loadout site and
inspected the "cut" slope on the north side of the loadout. It is
quite evident from these field investigations that the deposits at the
loadout site are not "unconsolidated stream laid deposits holding
streams". Angular shaped rocks of varying sizes (primarily composed
of sandstone) were noted throughout the "cut and fill" face of the
loadout which strongly supports the conclusion that these materials
