A Houston company that buried suspected cancer-causing PCBs along its natural-gas pipelines has agreed to pay the state a record $218 million in penalties and cleanup costs, officials said.

The agreement announced Tuesday calls for Texas Eastern Gas Pipeline Corp. to pay a $5.3 million fine. The rest of the money will go toward a 10-year cleanup at 19 sites and pay for monitoring of those spots.State officials learned from news reports in 1987 that Texas Eastern routinely buried fluids containing polychlorinated biphenyls in pits along its pipelines in 15 states. PCBs are used as lubricants and insulators.
