It's been nearly four years since the massive Enbridge oil spill in Marshall occurred, polluting waters in Calhoun and Kalamazoo counties. In July 2010, a rupture in pipeline 6-B allowed more than 800,000 gallons of oil to escape into the environment. There's now a civil lawsuit that's moving forward involving whistleblower" John Bolenbaugh. The former SET Environmental cleanup worker claims Enbridge was responsible for his termination from SET and he's also stated that he was harassed by Enbridge workers. He said this occurred after Enbridge instructed contractors to cover-up spilled oil with materials like grass rather than clean it up. After Bolenbaugh started making the accusations and documenting cleanup efforts, he said he was fired. He won a wrongful termination settlement against contractor, SET environmental. Now, he's going after Enbridge for what he says is the company's role in his termination of employment. Information that came out in the previous lawsuit is providing evidence in this new case. Meanwhile, Bolenbaugh said some of his claims of harassment include death threats that were left on his car and through electronic messaging, alleged assaults, [and] property damage including slashed tires. He said former security officer Garrett Murray, who worked for DK security, can back up his claims. Murray agreed to an interview and showed us a flier with Bolenbaugh's picture and stats on it, even his license plate number, saying, "all personnel be alert". He said it was posted on the wall.
