FRESNO — A federal investigation has found that a hazardous waste facility at the center of a birth defects controversy improperly disposed of a chemical known to cause cancer and reproductive problems.
Officials with the Environmental Protection Agency's San Francisco regional office sent a "notice of violation" Thursday to Chemical Waste Management in Kettleman City. The company runs the largest hazardous waste dump in the West.
At issue is the facility's handling of PCBs, or polychlorinated biphenyls, a banned transformer fluid.
Nearby residents have blamed the facility for at least 11 birth defects since 2007. Company officials have said there's no evidence linking the dump to the birth defects.
Company officials did not immediately calls for comment Thursday.
