Residents of Ponca City, Oklahoma, are reporting a mysterious black dust covering homes, pets, and playgrounds. Local community members and former plant workers identify the substance as carbon black, a powdery material used in tire manufacturing, and point to the Continental Carbon plant as the source. Despite numerous complaints filed with the Oklahoma Department of Environmental Quality (DEQ), many investigations were closed quickly. However, some records indicate the plant failed to control fugitive dust in 2024, reflecting a long history of pollution settlements and environmental concerns in the region.
