| While re-routing flow lines at the LDS-63N68W/24SWSE location, historical petroleum hydrocarbon impacted soil was discovered. It does not appear that the historical petroleum hydrocarbon impacted soil is associated with any active equipment on location. The petroleum hydrocarbon impacted soil is being excavated. Based on the volume of impacted soil excavated, the release was reported to the COGCC on August 21, 2015. Confirmation soil samples will be collected from the excavation and will be submitted for laboratory analysis of TPH, BTEX, pH, EC, and SAR (if applicable). The analytical results and excavation details will be provided in a supplemental report. A topographic Site Location Map depicting the general location of the release is attached as Figure 1. |
