The West Virginia Department of Environmental Protection is investigating a business in Poca after reports of a familiar smell that followed January's chemical spill.
The agency on Monday received reports of the strong licorice smell of MCHM coming from a business called Safety Kleen in the Poca industrial complex.
The smell is familiar to those in the Charleston area following the Freedom Industries chemical spill that tainted the water supply of 300,000 West Virginians.
WCHS-TV reports that an investigator on the scene said the company was cleaning a tank Monday, which is likely what caused the strong odor.
Air quality samples and other tests are being done as a precaution, but so far the agency doesn't think there's cause for concern.
