Alluvial Ground Water
Ground Water occurs in the alluvial deposits of Wilson, Taylor, Good Spring,
and Elkhorn Creeks. The applicant has stated' that a few wells and springs
locate along Good Spring Creek are used for stock watering. There is no
other known use of alluvial ground water by the residents in the vicinity
of'ahe mine.
Potential impacts to the alluvial ground water systems are discussed
in the AVF and Hydrologic Balance - Ground water portions of this document.
Generally, there is a slight potential for the quality of these waters to
be degraded. This potential is not considers significant enough to
warrant changes in the mining and reclamation plan. Rather, it can be
adequately handled through monitoring. If the monitoring as outlins in
the AVF and Hydrologic Balance - Ground Water sections of this document
is implemented, any changes in ground water chemistry resulting from
mining will be detected.
Pursuant to Rule 2.07.6(2)(c), the assessment of the probable consequences
of the proposs mining operation and the assessment of the probable
cumulative impact of a1Z anticipated mining in the area on the hydrologic
balance, as described in Rule 2.05.6(3), have been made. The proposs
operation has been found to be de§~gns to prevent material damage to
the hydrologic balance outside the permit area.

2.05.4 (2) (h) , 2.05.6 (1) , and 4.17
The climate at Colowyo is described as typical of a high plains, mid-
altitude region with warm summers and cold winters. Monthly temperature
and precipitation data from stations at Craig, Meeker and precipitation
data collected during 1978, 1979, and 1980 on the Colowyo permit area
is presented in Section 2.04.8 of Volume 1. Precipitation on the permit
area averages approximately 18 inches per year, with a significant portion
of'~the yearly precipitation resulting from snow during the winter and
spring.
Colowyo has obtained emission permits from the Colorado Department of
Health. The fugitive dust control practices ~nploys by Colowyo, including
haul road watering, asphalt paving, roadcut stabilization,.and dust
suppression facilities at the primary crusher and the Gossard Loadout are
outlined on pages 2.05-62 through 2.05-65 of Volume 1. Copies of Colowyo's
Emission Permits and air quality report prepared by Western Scientific
Services, Inc. are included in Exhibit 8, Volume 2.
Special stipulation No. 4 attache to the 1980 Increass Production permit
approval required that Colowyo obtain necessary air quality permits for
production at 4.5 million tons per year prior to excesing 4.0 million tons
per year. The inclusion of that stipulation in-:this document is appropriate.
