JEFFERSON CITY, MO FEB. 26, 2010 – Waste Corporation of Missouri has notified property owners near the Central Missouri Landfill in Sedalia of the possibility of increased methane gas migration in the area, the Missouri Department of Natural Resources announced today.

Waste Corporation of Missouri owns and operates the Central Missouri Landfill located at 24461 Oak Grove Lane. The facility notified surrounding property owners Monday of a monitoring well exhibiting one elevated level of methane. Only one person lives within a 1,000-foot radius of the well with elevated methane levels.

This reading is the first time methane has been detected in a monitoring well at the Central Missouri Landfill. The reading was above the regulatory limit but below the lower explosive limit.

Methane is a byproduct of the decomposition of waste and is explosive at concentrations between 5 and 15 percent. The regulatory limit for methane 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 constituent gases, such as hydrogen sulfide, which gives the gas an odor similar to natural gas.

The Department of Natural Resources encourages nearby property owners to use precaution and call 911 if they smell gas. For additional information, contact the Department of Natural Resources’ Solid Waste Management Program at 800-361-4827 or 573-751-5401.
