RE: Preliminary Adequacy Review
Our File 1182-11, "!lillyer Pit"
Dear Mr. Hillyer:
Z have completed my initial review of the application you submitted For a
mining and reclamation permit and I find that it does not adequately
consider the potential impact to the prevailing hydrologic balance of the
Animas River (both surface and alluvial groundwater systems).
2 have listed below the information I believe will be necessary for you to
supply before we can complete our review and make a recommendation to the
TSi ned Land Reclamation Board.
1) Exhibits B & C, Mining Plan and Map
„,;tt 6. I.akd
The specific area in which the proposed operation^has not been
identified such that its relation to the active reiver channel can be
considered. The river channel and the boundary of your S acre area must
be shown on a map. The development of the mining operation must be
illustrated (i.e. delineate phases on map and describe extraction scheme).
2) Exhibit D, Water Resources
It is our expectation that any "gravel farming" operation developed
in the main channel of an active river will directly affect the prevailing
hydrologic balance of that river. Now much aggregate do you propose to
remove from the river channel on an annual basis? Approximately what
fraction of the river's annual sediment load will this represent? 7low
many years do you expect to continue this extraction? The extent to which
your mining operation might cause a lowering or lateral relocation of the
river channel should be discussed. Are there bridges, dams, irrigation
ditch headgates, or other structures within one (1) mile upstream or down-
stream which might be affected? Do you have water rights to cover the
beneficial and consumptive uses involved in the proposed operation? (Note
that the State Engineer has been considering evaporative losses as a
consumptive use.) Have you applied to the Colorado Department of Health
for a NPDES permit? Fugitive Dust permit?
