| On October 5, 2015 Synergy began removing facility structures as part of P&A activities. The associated well head was shut in prior to infrastructure removal. Historical soil hydrocarbon impacts were observed within the excavation. Synergy contracted LT Environmental Inc. (LTE) to oversee remediation excavation and confirmation sampling of the impacted soils. On October 7, 2015, LTE collected 6 sidewall and 2 floor soil samples from the excavation for laboratory analysis of BTEX and TPH. Two of the sidewall samples exceeded the COGCC allowable concentrations for TPH. The current extent of the excavation is approximately 34 feet north-south, 50 feet east-west, and 13 feet deep. Impacted soils are presently being stored on-Site on plastic and will be transported under waste manifest to the Denver Regional Landfill in Erie, Colorado. Synergy will continue excavations of impacted soils and collect confirmation soil samples upon completion. |
