The Pennsylvania Department of Environmental Protection (DEP) fined Halliburton Energy Services $1.8 million for 255 violations of the Solid Waste Management Act occurring between 1999 and 2011 at its Homer City facility. The violations involved the storage, treatment, and transportation of waste hydrochloric acid. During the 12-year time period, Halliburton transported acidic waste, which had originated from various gas well sites, without identifying the waste as hazardous waste, without proper hazardous waste trucking records, and without using a licensed hazardous waste transporter. In addition, the company sent the hazardous waste to an unauthorized treatment and disposal operation.
