Su=face occupancy ar use is subject to the following special operating
.constraints. '
Underground' mining operations will result in surface subsidence. The
operator/lessee shall perform a study co secure adequate baseline data to
quantify the existing surface resources an and adjacent co ehe lease area.
Existing data may be used if such data is adequate for the intended
purposes, The seedy shall be adequate Co locate, qusnufy, and demonstrate
the inter-relationship of the geology, topography, surface hydrology,
vegetation and wildlife, Sase~line data will be established se chat furore
programs of observation can be incorporated at regular intervals far
eomparisou.
the operator/lessee shall eseablish~a monitoring system, to locate, measure
and quantify the progressive and final effects of underground mining
activieie'$ an the topographic surface, undergreund and surface hydrology
and vegetation. The monitoring system shall utilize techniques which will
provide a coneinuing record of change over time and an analytical method
for lacaeian and measurement of a member of poines over the lease area.
The monitoring shall incorporate and be an exten.^.ion of the baseline data.
IE subsidence activates a landslide which adversely affects serener
resources, or a documented worst lass, Che operacot shall (where
