JEFFERSON CITY, MO, DEC. 2, 2010– The Missouri Department of Natural Resources has issued a notice of violation to Republic Services Inc. for exceeding the regulatory limit for methane gas in one of the monitoring wells at the Show Me Regional Sanitary Landfill.  The landfill is located in Warrensburg, Johnson County.

The department required Republic Services to develop and implement an emergency gas management plan, including notification of residents occupying structures within 1,000 feet of the affected well.   Republic Services was also required to offer adjacent property owners installation and replacement of methane detectors as needed.

Landfill gas is a term for a mixture of gases, including methane, carbon dioxide and trace constituents of other contaminants that are byproducts of the decomposition of waste.  Methane is explosive within a certain range of concentrations, between 5 percent and 15 percent by volume. Methane is colorless and odorless. 

The department encourages nearby property owners to be aware of the potential for methane migration in the area and cooperate with Republic Services Inc. as they conduct methane monitoring and provide methane detectors to those within the notification area.
