Approximately 31 barrels of oil and 10 barrels of water were released into lined containment. A hydro-vacuum rig was utilized to recover approximately 22.5 barrels of oil and 5 barrels of water. The remaining impacted pea gravel/road base will also be recovered utilizing a hydro-vacuum rig. Confirmation soil samples will be collected from the release area or excavation, as applicable. The analytical results and excavation details will be provided in a supplemental report.

On December 18, 2015, five confirmation soil samples (B01@1’ through B05@1’) were collected from the base of the shallow excavation and submitted for laboratory analysis of TPH, BTEX, pH, and EC. Laboratory analytical results indicated that the TPH, BTEX, pH, and EC concentrations were compliant with the COGCC Table 910-1 allowable levels in all five soil samples. Approximately 90 cubic yards of soil was excavated and transported to the Buffalo Ridge Landfill in Keenesburg, Colorado. The hydro-excavated soil slurry was taken to Waste Management’s CSI facility in Bennett, Colorado. The general site layout, release location, excavation dimensions, and soil sample locations are depicted on the Excavation Site Map provided as Figure 2. The soil sample analytical results are summarized in Table 1 and the laboratory analytical report is attached.

Laboratory analytical results for the confirmation soil samples indicated that TPH, BTEX, pH, and EC concentrations were in compliance with COGCC Table 910-1 allowable levels at the extent of the excavation.
