Local quarries could soon be under new ownership.
Hanson Aggregates and Heidelburg Cement of Germany might join forces to become the second largest in the industry worldwide.
Negotiations on the multi-billion dollar sale are anticipated to be finalized during the third quarter, according to postings on the companies' Web sites.
The two companies together would be a powerhouse in the building material industry with a combined 70,000 employees and revenues of more than 15 billion euros.
Hanson is one of the world's largest suppliers of heavy building materials and employs more than 26,000 workers primarily in North America.
The company produces aggregates, asphalt, ready-mixed concrete and cement.
Wagner Quarry in Perkins Township, Sandusky Crushed Stone in Groton Township and Flat Rock Quarry in Seneca County are all Hanson-operated quarries.
Problems erupted in Groton Township in 2006 when residents complained of the aggravation they suffered from the dirt, dust and noise.
Hanson Aggregates and Groton Township Trustees made peace earlier this year with a settlement requiring Hanson to pay mining impact fees and occupy a smaller mining area.
Resident Earl McKinney said he is hopeful the German company will provide the best route for the local quarries. He worries about the security of the jobs of local workers.
"We want to be assured that people who are working at these quarries won't lose their jobs," he said.
Heidelburg Cement has been in the U.S. since 1977. It also has locations in the Gulf Coast, Pacific Coast and Western Canada.
The North American market is so large with a demand so high, according to Heidelburg's Web site, the only way to meet the need is importing from other regions.
The German network, along with Hanson, would be able to provide its biggest market with combined efforts that could strategically create a stronger market, according to company information.
