In terms of Federal lands, the re-assessment demonstrated there are no identified spring, seep or pond
features under which planned coal mining activities will take place, that would be classified as "high
value" hydrologic resources.
With respect to the three "high value" resowces located on private lands, OMLLC has commitments
within the CDMG Permit C-1981-022 (permit page 2,05-88) to work with "area land owners to restore,
replace or provide reasonable compensation for any significant livestock watering sources that are
adversely impacted". Given the thickness of overbwden cover in the vicinity of these resources (in
excess of 2300') coal mining activities are predicted to cause no "injury" to these hydrologic resources.
With respect to Bear creek, please see the discussion in a later section.
2. SITES NEVER FOUND OR LOCATED.
A number of hydrologic sites previously identified in the Elk Creek lease could not be Found and
assumed to never exist. The reference to the following sites on the revised CDMG permit Map 2.04-M2
Regional Geology/Hydrology have been deleted.
ECP-1
ECP-8
ECSP-10
ECP-11
ECSP-12
ECR16
ECSP-18
ECSP-19
ECSP-21
ECP-24
ECSP-28
3. SITES LOCATED WITHIN THE LEASE AND CDMG PERMIT AREA BUT LOCATED
OUTSIDE OF THE PLANNED MINING AREA.
These sites are located within the CDMG permit area and within the Federal coal lease but are not
located above planned coal mining activities. These sites are shown on Map 2.04-M2 Regional
Geology/Hydrology.
ECP-26
ECSP-30
ECP-31
Pond ECP-26 appears to be a man-made runoff only pond. The source of water comes from an up
gradient slide/erosional feature located in fine textured clay soils that readily sheds water during
significant runoff events.
ECSP 30 is a "high value" man-made pond fed by the perennial and reliable "Desty's" spring ]ocated
nearby. Because of the perennial flow from the spring, this pond contains water into the fall months.
ECP-31 is a man-made runoff pond designed to captwe spring runoff. This pond was dry by fall.
4. SITES LOCATED OUTSIDE OF EITHER THE LEASE AREA OR CDMG PERMIT AREA.
A number of sites are located outside of the limits of the Federal coal lease or outside of the CDMG
permit area. A number of sites (beginning with site ECSP-29) were new sites added to the inventory.
These sites do not lie above planned coal mining activities. These sites are shown on Map 2.04-M2
Regional Geology/Hydrology.
