Ohio EPA Approves Rumpke Landfill Odor Control Plan

The Ohio Environmental Protection Agency (EPA) has granted Rumpke Consolidated Companies Inc. its request for its landfill in Colerain Township, Ohio, to increase odor neutralizer at the site.

The Cincinnati-based company said in a news release that a new pilot study indicates an alternative odor minimizer may be an option as well. It’s a liner designed to reduce odors.

“We are observing a reduction in odors and just recently we have been able to slightly reduce use of the odor neutralizer, " said Amanda Pratt, Rumpke director of communications.

Rumpke requested the increase in odor neutralizer use in part to eliminate odors coming from a reaction occurring in a small area of the landfill, the company said at the time. The reaction is occurring 100 feet below the landfill’s surface, is not a fire and poses no health risks.

With the new permit Rumpke can use 2,741 gallons of odor neutralizer mixed with more than 2.7 million gallons of water monthly, the company said. The company distributes the odor neutralizer through more than 200 spray nozzles attached to more than 6,100 feet of hose, 20 industrial fans and mobile spray dispensers.

Rumpke has taken some other steps to control the odors, such as installing trenches to capture the odors and adding odor control blankets.
