If the global environmental organization gets its way, loopholes in last year's Definition of Solid Waste Rule will be eliminated.

Designed to make it less expensive for manufacturers to recycle secondary hazardous materials such as sludge, it requires the materials to be “contained” without defining what that means and allows “intermediate facilities” to store the materials before reclamation.

The Sierra Club has asked EPA to repeal the rule change, claiming that it allows haulers to transport and store the waste without adhering to federal laws, essentially deregulating 1.5 million tons of garbage. The agency has indicated that it won't repeal the change, but is considering revisions.

The agency estimates that the change diverts secondary hazardous materials from 5,600 landfills and recycling centers.
