WASHTENAW COUNTY, Mich. – The Rover Pipeline Project was issued a violation notice Friday after Michigan Department of Environmental Quality staff members smelled petroleum in water being discharged from the pipeline.
According to MDEQ, the Water Resources Division received a complaint Wednesday about an odor near the Dexter-Townhall Road crossing in Washtenaw County.
When the site was inspected Wednesday, staff members said they noticed a petroleum smell and saw a sheen in the dewatering enclosure.
On Thursday, the Remediation and Redevelopment Division inspected the site and noticed the smell. The division also saw a former gas station near the dewatering area. The workers collected samples of discharged water.
According to MDEQ, the source of the petroleum is likely to be contaminated groundwater from the former gas station that is being captured through the dewatering process.
Discharge from the site enters a nearby wetland. Since the water is contaminated, there must be National Pollutant Discharge Elimination System Permit coverage. If the site continues without a permit, it will be in violation of the Natural Resources and Environmental Protection Act.
Also, water withdrawal must be registered with MDEQ if the pipeline has the capacity to pump over 100,000 gallons per day, averaged over any consecutive 30-day period. The pipeline must register to avoid being in violation.
The Rover Pipeline must cease unauthorized discharges and register water withdrawal as necessary.
A written response confirming intents and summarizing actions by Rover Pipeline, LLC must be submitted by Oct. 18.
