The Department of Transportation’s Pipeline and Hazardous Materials Safety Administration pledged June 13 to work with the Rechargeable Battery Association and the International Association for the Promotion and Management of Portable Rechargeable Batteries on a proposal to include a special provision and packing instructions for waste lithium batteries in international regulations. The proposal requests that the U.N. Subcommittee of Experts on the Transportation of Dangerous Goods, which meets June 25-July 4, consider exempting waste lithium ion batteries from some new regulatory requirements if they are shipping in accordance with new packing instructions.
