The document summarizes the response to an oil pipeline spill in the Yellowstone River near Glendive, Montana. Initial test results found elevated levels of benzene in Glendive's water supply, prompting officials to advise residents not to drink or cook with the water. While above long-term safety standards, the CDC said the contamination did not pose short-term health risks. Officials pledged to improve public notification procedures in future environmental disasters. The governor and pipeline company accepted responsibility for the spill and its cleanup.
