Observations F Zowin Visit to Colony, Union
and Logan Wash
I forward the following observations made during a visit by Jerry Zimpfer
and myself to the Colony, Union and Logan wash oil shale projects on June 9th
and 10th.
Observations at the Colony Site
Jerry and Z toured the site in the presence of Ace Bischard, and Bi1Z Parent,
both with Exxon U.S.A. In general construction appears to be proceeding as
scheduled. Access roads should be complete by this fall. Construction on
the fill at the plant site is beginning in earnest. The road from the plant
site to the disposal site is in the surveying staking stage and is about to
commence construction. Construction on the Middle Fork Dam is in the.pre-
liminary stages of foundation cleaning and grouting. The only item which
appears to be behind schedule is the final construction of the mine portal
bench. Portal development was suppose to begin on June 1 and appears to be
a month or so behind schedule.
The most immediate concern voiced by Exxon's personnel, is the acquisition of
approval for topsoil stockpile Locations. The need is apparent. Topsoil is
being lost in transferring it from one temporary pile tp another in order to
allow for road and dam construction. The worst problems exist within Davis
Gulch and.MiddIe Fork Valley. The three temporary "approximately one year
in Life" stockpile sites in Middle Fork Valley appear acceptable. In actuality
there appears to be no option due to the extremely confined working space above
the Middle Fork Dam site. Exxon indicated that they will submit detailed plans
for these stockpiles in the near future. I.vgge.sted verbal approval of the
southern most site so that they might begin depositing topsoil immediately-
The proposed topsoil stockpile sites within Davis Gulch also appeared acceptable.
Those which are located above the high stand line for the flood pool behind
Davis Gulch Dam will be no problem. Those which are located below that high
stand line should be relocated before any appreciable likelihood of inundation.
Exxon also indicated that amended final plans for these stockpiles will be
submitted in the near future.
The ridge-top site above the disposal area appears to he acceptable. Wind
erosion will probably require some close scrutiny in control until the pile
can be vegetated. In addition, they pointed out two additional sites which
they will propose near the head of each disposal valley site. These stockpile
