The Pennsylvania Department of Environmental Protection (DEP) has fined a subsidiary of Halliburton Co. $1.8 million for 255 violations of the state's Solid Waste Management Act between 1999 and 2011. The DEP on Tuesday said Halliburton had waived its right to appeal and signed a consent agreement for the fine against subsidiary Halliburton Energy Services. DEP became aware of the violations in 2011 during an inspection of a Homer City facility in Indiana County, PA. Inspectors discovered that Halliburton had stored, treated and transported hydrochloric acid waste without obtaining proper DEP permits. A further investigation revealed that the company had committed the violation on multiple occasions to 1999. DEP said between 1999 and 2011 Halliburton transported acidic waste that originated at well sites without identifying the waste as "hazardous," without the proper trucking permits and without using a licensed hazardous waste transporter. Additionally, the company sent the waste to an unauthorized treatment and disposal operation. The DEP said no evidence suggests the waste handling caused any harm to the public or environment.
