CHARLESTON, W.Va. (WSAZ) -- The West Virginia Department of Environmental Protection says there was no runoff at Freedom Industries following a heavy rainstorm Thursday.
Inspectors were on scene Thursday, before and during the storm, to ensure that all controls related to containing runoff were in place and being properly executed.
The controls were put in place last week after two overflows of the stormwater collection trench at the site.
The corrective measures include raising the berm along low spots of the trench, including the spot where both of last week's overflows occurred, installing an extra backup pump so that there are now a total of three pumps along the trench, and implementing 24/7 monitoring at the site.
The steps were outlined in a plan submitted to the DEP Saturday in a response to one of three notices of violation the agency issued because of the overflows.
The DEP says they will continue to closely supervise all activities at the site, including the stormwater collection controls in place to keep water that comes into contact with potentially contaminated soil from getting into the Elk River.
A tank at the site leaked 10,000 gallons of crude MCHM, a frothing agent used in the coal cleaning process, on Jan. 9. The material made its way to the river and contaminated the drinking water for approximately 300,000 West Virginians.
