Soils Report
As shown on the soil survey map below, soil on the Pronghorn Compressor Station site is comprised of
Valent sand, 0 to 3 percent slopes. Information on soils and their limitations came from the USDA, Weld
County Soil Survey.
On-site soil tests were conducted by Terracon Consultants Inc. (Soils Report attached). The foundations
for the compressor facilities will be designed in accordance with the geotechnical engineer's
recommendations. No particular geotechnical hazards are anticipated during the design and construction
of the compressor station.
Legend: 69 - Valont sand, 0 to 3 percent slopes
70 - Valent sand, 3 to 9 percent slopes
