remaining disturbed areas not yet reclaimed include sediment ponds and some features that SCC
has planned to retain permanently.
Impacts to surface water and ground water have been and will continue to be mitigated and
monitored. Surface runoff from all disturbed areas is channeled to a sedimentation pond. Ponds
10, 11, 11 a, 12, 12a, 13, and 14 have been constructed to date.
Surface water is monitored upstream and downstream of the site on Grassy Creek, Annand Draw,
and Sage Creek. Ground water is monitored in the Trout Creek aquifer, in spoils aquifers,
natural springs, and in the alluvium of Sage Creek, Grassy Creek, Annand Draw tributary, and
Grassy Creek tributaries.
Water usage at the mine consisted of dust control on roads and in pit areas. Water used in dust
control was obtained from Pond 002 at the Seneca II Mine. Seneca Coal Company has obtained
rights for all water usage at the operation.
