| On, January 19, 2017, historical hydrocarbon impacts were observed during hydrovac activities around the wellhead. The limits of the hydrovac excavation were approximately 6 feet by 3 feet by 1 foot deep. No groundwater was encountered. One soil sample was collected for BTEX and TPH analysis. Laboratory analytical results were received on January 31, 2017. TPH concentrations were 7,600 mg/kg and benzene concentrations were 9.1 mg/kg. These concentrations exceed the COGCC Table 910-1 allowable limits. Delineation of the soil impacts is ongoing. |
