The line was immediately shut off and blown down. Locates were called in and a request to close a lane on CR 40 1/2 were submitted in order to perform our excavation and repair as soon as possible. A 3rd party soil remediation company will be onsite with a hand held photo-ionization detector (PID) to help determine the extent of the hydrocarbon impacted soils. More information will be provided in the 10-day follow up report. 400829125 true 2015-04-21T00:00:00-06:00 40.284042 -105.022760 OTHER (SPECIFY) Private 0 1 0 false <_x0032_7_approved>false S false 0 >=1 and <5 0 0 0 false false false false true 0 2015-04-22T13:07:13.767-06:00 400835476 Because we believe groundwater has been impacted, as soon as we receive water sample results we will move forward with the generation of a Form 27.

Once PID readings were showing low enough, six sidewall soil samples were collected from the excavation as illustrated on the attached figure and submitted for quick turn analysis for BTEX, GRO, & DRO. Analytical results indicate that all soil samples were below COGCC standards. Based on visual evidence, it appears groundwater may be impacted. Water samples were sent to the lab and we are awaiting the results.
