P.E: Written Findings
for Colorado Coal
Kline No. 1, File No. C-029-81
This memo contains findings for the following sections: Geology, Ground
Water, Surface Water, Probable Hydrologic Consequences of Mining, and
Cumulative Hydrologic Impacts Assessment, Water Rights and Replacement,
and Backfill and Grading. The lack of surface water baseline is still a
serious problem with the permit. The surface Boater section contains
seven stipulations which essentiallq stipulate nn ade7uate surface water
monitoring nroyram.
A number of verbal agreements made to the Division by Perma Resources
need to be put down in writing and the mine plan amended to reflect these
agreements. The agreements which siginficantly effect the enclosed findings
are: 1) The 500 foot buffer zone on either side of Maitland Arroyo,
Gordon Arroyo, and the unnamed tributary to Maitland Arroyo; and 2) the
prohibition of mining within, or dewatering of old, flooded underground
coal mines until the State Engineer's water rights and the Colorado
Department of Health's water treatment concerns have been resolved.
Another concern, which has been noted and not subject to any agreement,
is the selective placement of coal processing wastes within the backfil2ed
areas. These agreements may significantly effect the mine plan for the
Colorado Coal Ffine No. 1. The following maps, drawing and texts changes
should be submitted prior to permit issuance:
1) The applicant should submit a map delineating the area where flooded
old mine workings exist. The applicant should also submit a series
of cross-sections which show the depth to the flooded mine workings.
2) The applicant should amend the mine plan map and any related maps
affected by the rtune plan amendment (i.e., topsoil handling map,
reclamation maps, vegetation maps, post-mining topography maps, etc.).
The "Mine Plan" map should delineate mining of coal seams above
the flooded mine workings and the 500 foot stream buffer zones
(e.g., time sequence of mining and mine limits).
