US: Residents living near Essroc's cement plant and quarry at the south end of Martinsburg, West Virginia have claimed that dust coming from the plant has coated their vehicles and made it difficult to keep them clean. "If I wanted my vehicle to stay clean, I would have to go to the car wash every day," said Thompson Street resident Melissa Kneisly.

According to local media, Essroc officials said that they have taken multiple steps to keep dust from becoming airborne and leaving their facilities after receiving multiple complaints from nearby residents. The increased number of trucks hauling clinker to Pennsylvania caused the extra dust to be kicked up from the loading of the trucks and transportation on the roads, according to Environmental Manager Bradley Blasé. In recent weeks, the number of trucks leaving the plant has nearly doubled to 50/day as a result of a special operation. Besides truck traffic, Blase also cited dry and unfavourable weather conditions for contributing to the dust problem. Plant Director Heinz Knopfel said that the plant has increased the sweeping of roads and watering as part of efforts to contain the dust.

Jake Glance, a spokesman for the West Virginia Department of Environmental Protection (DEP), said that the agency is aware of the dust situation and has had an inspector from the Division of Air Quality looking into the issue for several days. "The situation is still under investigation and right now, the DEP cannot speculate on what the dust is or where it is coming from," said Glance.
