HUNTERSVILLE, N.C. (WBTV) - The North Carolina Department of Environmental Quality is reviewing an updated volume estimate submitted today by Colonial Pipeline Company under the terms of the 2022 Consent Order.

According to the document submitted today, Colonial estimates a volume of two million gallons of fuel released in the Oehler Nature Preserve near Huntersville, making it the largest onshore fuel spill in the nation.

The document states Colonial has recovered more than 35,500 barrels of fuel so far.

“While the estimated released volume has been updated, the extensive 385-plus subsurface monitoring and recovery well network we have in place is working as designed,” representatives from Colonial wrote in the release.

The spill was discovered in August of 2020.

The order also requires the company to take specific remedial actions and pay nearly $5 million in penalties and investigative costs.
