The Ohio EPA is holding a public hearing Tuesday night on Rumpke's request to increase the amount of odor neutralizer being used at its Colerain Township site. The new permit would allow the company to use up to 2,741 gallons of the neutralizer mixed with more than 2.7 million gallons of water monthly.
The deodorizer is made from essential plant oils, mainly from fruits and vegetables. It's applied using 200 spray nozzles attached to more than 6,100 feet of hose, 20 industrial fans and mobile spray dispensers
