4.1 SITE STANDARDS
4.1.1 Toooaraohv
Elevations vary from a high of 4850' above mean see level on
the west side of the property to a low of 4770' on the
northeast side of the property.
The lend is gently rolling with maximum slopes of lOr. and
general slopes of lx or less.
The land is sand sage prairie habitat with many blowouts. The
larger blow outs have the steeper slopes generally on the
southeast sides where the prevailing winds have scooped them
out. There are na drainages end no erosional features as the
deep surface sands readily absorb all of the possible runoff.
Although there are many hollows due to the blowouts, water
never accumulates in these Rollows.
4.1.2 Flood Plains
Refer to Sec. 4.5.5, Aah Disposal on or adjacent to Alluvial
Valley Floors and Flood Plains.
4.1.3 Through 4.1.6
Please refer to Sec. 4.5.1, Description of Hydrology. Also,
refer to Appendix A, Water Resources and Impact Evaluation
Report.
4.2. ENGINEERING DESIGN STANDARDS
4.2.1 From test results completed by Hazen Research, Inc., it
was determined that the ash material is not a pollution hazard
to the ground-water or surface water system at the disposal
facility. Analyses reports and additional comments are
presented in Appendix B, Ash Test Results.
4.2.2 No surface water stream, pond or lake exists within a
limit radius of the proposed disposal site. In addition,
there are no surface water diversions, structures, berms,
channels, canals, or ditches used for the watering of
livestock or irrigation needs.
.4.2.3 Refer to Section 4.4.4, geologic hazards.
.4.2.4 Refer to Appendix A, McWhorter Report, for monitoring
