October 03, 2013 — By Julie Smyth, Columbus, Ohio (AP) — Environmental regulators in Ohio are investigating the cause of a significant spill of the clay lubricant bentonite during construction of an underground pipeline in eastern Ohio. Ohio Environmental Protection Agency said the material was released Tuesday in Harrison County, northeast of Cadiz. The material ran into Conotton Creek and directly impacted two private homeowners. The EPA was assessing enforcement options against the contractors, Southeast Directional Drilling Co. The ATEX pipeline will extend across 265 miles in Ohio and parts of three other states, connecting to existing lines to transport liquid hydrocarbon products between Pennsylvania and Texas.

Of the nation’s 240,000 miles of NATURAL GAS gathering lines, only about 10 percent are regulated. When leaks or accidents occur on the remaining 90 percent, operators aren’t required to notify regulators. In most cases, state and federal officials don’t even know where these lines are located.
