Rumpke receives permit to increase odor neutralizer

COLERAIN TOWNSHIP, OH (FOX19) - Rumpke Sanitary Landfill has received its air permit from the Ohio EPA to increase odor neutralizer use at its Colerain Township site.  However, a new pilot study indicates an alternative odor minimizer may offer options.

"Although the newly issued permit allows Rumpke to utilize more of the odor neutralizer, our Company has continued to research additional options for odor minimization," explains Amanda Pratt, director of communications at Rumpke.  "During the last month, we have piloted a liner designed to reduce odor impacts. We have installed 10 acres of the liner over sections of the reaction area. Early results indicate success. We are observing a reduction in odors and just recently we have been able to slightly reduce use of the odor neutralizer."

Rumpke began using environmentally safe odor neutralizer in 1998 to minimize the impact of odors. The odor neutralizer is made from plants and fruits.

For every gallon of odor neutralizer used it is mixed with approximately 1,000 gallons of water. With the new permit, Rumpke can use up 2,741 gallons of odor neutralizer mixed with more than 2.7 million gallons of water monthly.

The odor neutralizer is distributed via 200 plus spray nozzles attached to more than 6,100 feet of hose, 20 industrial fans and mobile spray dispensers.

Odor neutralizers are common in the waste industry. The deodorizer poses no health risks as it is made from non-toxic substances-essential oils from plants, mainly fruits and vegetables, the same essential oils used to make household deodorizers, cooking oils and flavor enhancers.

Air around the site is monitored by Hamilton County General Health District, Southwest Ohio Air Quality Agency, Ohio EPA and US EPA, all records are public. Rumpke continues to meet or exceed Air Quality Standards.

Rumpke originally requested  an increase in odor neutralizer use in part to eliminate odors resulting from a reaction occurring in a small area of the landfill. The reaction is occurring 100 feet below the surface of the landfill. It is not a fire and poses no health risks. Since the reaction began, Rumpke's team has worked with environmental experts to determine the best steps to manage it and its effects, one of which includes increased odors.
