Justice Department sues Norfolk Southern over Ohio train derailment.

The US Justice Department has filed a lawsuit against Norfolk Southern over the train derailment in Ohio last month, accusing the company of violating the Clean Water Act and unlawfully polluting the country's waterways. The suit seeks to hold the company accountable for the full cost of the environmental cleanup, with a penalty of $120,000 for each day it is found to be out of compliance. The derailment caused hazardous materials to enter the soil and waterways, killing thousands of aquatic animals. Norfolk Southern has paid over $24 million in reimbursements and cleanup costs.
