permittee shall submit the material balance to the Division
according to the schedule on page 21.4 of Chapter V, Volume 7 of
the application.
On pages 21 .3 and 21 .4 of Chapter V, Volume 7, Mid-Continent
Resources, Inc. , proposed to satisfy these stipulations in three
phases:
The first phase, consisting of a report and complete map-
ping of the mine portal benches and the haul road system, was
prepared by Geo-Hydro Inc. , and submitted to the Division.
Phase II , consisting of a detailed reclamation backfilling
and gradinq design, was developed for each problem area on the
mine pads and haul roads and was included in the Mid-Continent
Resources Inc. permit application.
Phase III consisted of the actual preparation of the test
plots near #4 Mine, and a yearly evaluation of the success or
failure of the test plots.
The purpose of this report is to assess the status of the
individual test plots and to make any changes, if necessary, to
the reclamation plan for the mine pads and haul roads.
TEST PLOTS
In 1984, Mid-Continent Resources, Inc. , prepared four test
sections near #4 Mine that simulated areas on the haul roads and
mine pads that might prove difficult to reclaim at the end of
mining activities. Figures 1 and 2 show the plan and profiles of
these individual test sections. The four test sections include
six potential problem areas of reclamation. These sections are
as follows:
Section 1 includes a high soil cut in a road and a high rock
cut in a mine bench.
Section 2 includes a high thick fill in a road and a high
thick fill in a mine bench.
Section 3 is a high thin sliver fill .
Section 4 is a severe erosion area.
Figures 3 through 7 conceptually show the individual test
sections.

On November 3, 1987, Bruce Collins, a Professional Geologist
and Ph.D, and myself , a Registered Professional Engineer in the
State of Colorado, carefully examined and photographed each of
