UPDATE 4:10 p.m. (By Howard): Le Roy Fire Chief Tom Wood said about 13,000 gallons of fertilizer spilled. The Department of Environmental Conservation and Genesee County Emergency Management also responded. The location is a transfer station and employees were operating a valve when there was a leak and fertilizer got on them. They shut off the valve and left to wash and change and when they returned, they discovered the valve had failed, causing the leak. Heavy equipment is on scene now beginning remediation.The spill area is about 50 yards wide and the soil will need to be removed and taken to a remediation site.
