State and federal officials have tentatively agreed to a $760 million plan to cleanup most hazardous waste at the Los Alamos National Laboratory by 2015.

Charlie de Saillan, an attorney for the New Mexico Environmental Department, Wednesday released a revised proposed consent order, which requires a cleanup of groundwater, soil and sediment, the Santa Fe New Mexican reported.

All the historical contamination that has been there since the 1940s will be eliminated, he said.

State officials and the U.S. Department of Energy have worked nearly two years on the draft agreement, but there will be a public comment period. The energy department and the University of California, which runs the lab, must sign off on the pact.

The proposed agreement does not cover radioactive waste, and there are critics of the deal who contend the state lacks power under the deal to force the actual cleanups.

Greg Mello of the Los Alamos Study group said there are no actual cleanup orders in the agreement, but the closest is the proposed groundwater cleanup.
