Kansas Group Wants Grass Burning Limits for Flint Hills

A Kansas environmental group is urging the U.S. Environmental Protection Agency to order the state to impose tighter controls on grass burning in the Flint Hills region.
The Lawrence Journal-World  reports the Kansas chapter of the Sierra Club wants the agency to order the Kansas Department of Health and Environment to adopt a mitigation plan to protect air quality in the region.
Ranchers in the Flint Hills burn grasslands in the spring to kill off invasive weeds and shrubs, creating thick smoke that some officials say is a concern for people with respiratory issues.
