define renewable resource lands as follows:
RULE 1.04 (110) - "Renewable Resource Lands" means aquifers
and areas for the recharge of aquifers, areas for
agricultural or silvicultural production of food and fiber
and pasturelands.
In the context of assimilating baseline information for the
permit application, land use information was collected and is
presented in Section 2.04.3 (Vol. I, pp. 76-79) and in Section
2.04.10, Attachment iI. As described in these sections, the
current land use is classified as wildlife habitat and/or
rangeland and mining. Annual vegetative production ranges from
400 to 1,600 pounds air dry forage per acre (AVM). There are no
• croplands or cultivated pasturelands on the property. We are
aware of no current or historic silviculture practices on or near
the permit area.
The groundwater hydrology of the area is described in
Attachment III of the application. In summary, the geology of
the area is characterized as being lenticular in nature with no
continuously mappable aquifers in the strata overlying the seam
to be mined. The nearest continuous unit capable of transmitting
small to moderate quantities of water is the Trinidad sandstone
formation located stratigraphically 300-400 feet below the
proposed mining activities, and therefore, subject to no impact
as a result of Dorchester's operations.
On the basis of the information contained in the referenced
• sections of the application and briefly summarized above,
