JEFFERSON CITY, MO MARCH. 22, 2010 – The owners of the Rumble I Landfill in Sugar Creek recently notified surrounding property owners of the possibility of increased methane gas migration in the area, the Missouri Department of Natural Resources announced today.   

Rumble 1 Landfill, located at 1950 N. Courtney Road, is owned and operated by Waste Management, Inc.  The facility provided notification letters on March 2 to property owners within 1,000 feet of a monitoring well exhibiting methane levels above regulatory limits.  The Lafarge mining facility was the only structure within the notification area.  The Sugar Creek owns all other property within 1,000 feet of the monitoring well and the property is undeveloped.

The Department of Natural Resources has been working with Waste Management on periodic methane issues at the Rumble I Landfill since 2005.  The Rumble I Landfill officially closed in 1999 and consists of approximately 46 acres of waste on a 68-acre site.  The majority of methane and other gasses generated by the landfill are collected through a series of gas extraction wells and transferred through a pipeline to be used as alternative fuel by nearby industries. 

The Department of Natural Resources is requiring Waste Management to evaluate the extent of any gas migration that may be occurring and develop a corrective action plan to protect human health and safety and ensure the facility meets regulatory requirements for controlling landfill gas within their property boundaries.

Methane is a byproduct of the decomposition of waste and is explosive at concentrations between 5 and 15 percent.  To protect public health and safety, the regulatory limit for methane found in the soil at a landfill property boundary is 2.5 percent, by volume.  Methane is an odorless, colorless gas, but when generated from waste decomposition in a landfill, it is often associated with other gases, such as hydrogen sulfide, which gives the gas an odor similar to natural gas. 

The Department of Natural Resources encourages nearby residents to be aware of the potential for methane migration in the area and call 911 if they smell natural gas.
