Narrative
Markwest operation's personnel had loaded a pig into the launcher barrel to be pushed with nitrogen to displace the crude oil in the pipeline for abandonment. A 2" drain valve on the launcher barrel was accidentally left partially open allowing crude oil to fill the sump. Eight (8) barrels of crude oil spilled out onto the ground, but was contained on our launcher property. A vacuum truck was on-site for the operation and it was used to sucked up the spilled crude oil that was returned the pipeline system. The contaminated soil was sucked up separately and placed in a contained vessel for testing and non-hazardous disposal.
