Gov. Rick Perry has asked lawmakers to explore establishing a location in Texas to store the state’s high-level radioactive waste.
A bill that would have dramatically changed the rules for a radioactive waste dump died in the Legislature because of a parliamentary error.
On Wednesday, state regulators gave approval to begin disposing of waste.
Environmentalists say trucking the waste on state highways is dangerous and fear the burial site could lead to underground water contamination.
Texas officials are set to give final approval to allowing low-level radioactive waste from 38 states to be brought to a Texas burial dump.
