RE: CERTIFICATION OF RECYCLE IIvIPOUNDMENT POND N0.2,
SOUTHFIELD MINE, FLORENCE, COLORADO (3rd Quarter, 1997)
Dear Al;
On September 17, 1997, an inspection was conducted on the Recycle
Impoundment Pond No. 2 currently in place at your Southfield mine. The inspection was
performed by myself, John Effinger III, a registered professional engineer in the State of
Colorado since December, 1975. I have experience and knowledge in the design and
construction of dams, drainage control, hydrology and structures; including experience in
portions of the permitting process of coal mine facilities and permit compliance.
The purpose of this inspection and certification was to check for structural
weakness, erosion, other hazardous conditions and identify required maintenance and to
satisfy the requirements of Rule 4.05.9 (13) of the Colorado Mined Land Reclamation
Board for Coal Mining. In addition to the on site inspection referenced above, actions
taken in preparing this certification included review and discussion of applicable mine
maps and state regulations with yourself.
Said inspection was performed on a mild, partly cloudy Wednesday morning by
myself. Most of the site was traversed with a four wheel drive vehicle with frequent stops
and hiking trips around the impoundment. The following is a statement of my professional
observations and conclusions from this inspection:
The entire impoundment was examined for structural weakness, erosion, tears to
hypalon lining and other hazardous conditions.
Small amount of influent into pond at time of this inspection.
Existing water level was 18" below the maximum level line.
Aquatic plant growth beginning in southwest corner of pond.
