Owners of a rock quarry south of De Soto got approval to expand mining operations last week, over the objections of neighbors who said the blasting and dust are creeping too close to their homes. Officials of Martin Marietta, which owns the Sunflower Quarry, maintain they have been good neighbors and have taken pains to limit blasting and inform nearby residents about their operations in western Johnson County. On Thursday, they asked the Board of County Commissioners for permission to expand their mining area because of increased need for crushed rock in construction projects.
