A proposal to expand operations and build a concrete mixing plant at North Staffordâs Vulcan Materials quarry is raising concerns among some nearby residents who say the expansion will bring more trucks, noise and dirt to their suburban neighborhood. âThe whole thing is nothing but a disaster,â said Jeff Eastland of Toluca Road. âThe dust from that cement plant is going to affect everybodyâs health, not to mention the extra trucks and everything else that they are doing.â Eastland and his wife, Elena Prokos, have lived on their 7-acre farm just west of the quarry since 1999. One of Eastlandâs concerns with the new mixing plant is its possible impact on the small pond on his property that is brimming with vegetation and wildlife.
