The 760 mile pipeline that runs diesel from Salt Lake to Spokane has been repaired. It was a 72 inch seam that split open which allowed the 20,000 gallons of diesel to spill into Willard Bay. That's been fixed and the chevron pipeline is back up and running at 80%.
The Director of Utah’s Division of Water Quality Walt Baker explained, "The federal DOT has allowed them to put product back into that line and keep it at a lower pressure than it would be normally operated at."
The Pipeline and Hazardous Material Safety Administration says while the investigation into why the Chevron pipeline failed, the company did meet the requirements needed to restart.
Damon Hill, a spokesperson for PHMSA told ABC 4 News, "They actually conducted testing, did the repairs that were necessary, that we felt were necessary, in order to return the pipeline to service."
The state has no say in pipeline operations, but was told before the pipeline can be re-opened to 100% pressure more testing needs to be done.
"There will be additional hydrostatic testing,” said Baker. “They put water into the pipeline and then test at full pressure and beyond that to see if it's functioning okay."
Meanwhile the DWQ has learned the diesel has now seeped into the ground water.
“There's product making its way out to the bay,” said Baker. “We're seeing hits out beyond the booms and although they're low levels they are still there."
The contamination levels at this time are not high enough to harm humans or wildlife, but the DWQ says there could be some impact if the diesel continues to seep into the ground water.
