The company that owns the smoldering Bridgeton Landfill has 20 days to submit a new plan to stop the fire's spread toward radioactive waste buried at the adjacent West Lake Landfill.
The Missouri Department of Natural Resources yesterday found "significant deficiencies" in Republic Service's contingency plan.
Residents living near the two landfills have expressed serious concerns about the underground fire that continues to creep closer to the radioactive waste site.
Missouri Attorney General Chris Koster sued Republic in March because the continuous burning violates state environmental laws. Koster says he will take them back to court if necessary to force the company to comply with the DNR's request for a new plan.
