Rule Drafted for Carbon Trapping
The Environmental Protection Agency announced on Tuesday a first draft of a rule that will govern injecting carbon dioxide into underground storage. Development of such a rule is essential before companies can build power plants that will capture and store their carbon dioxide to limit the buildup of global warming gases. The agency acted under the Clean Water Act because injecting carbon dioxide might push pollutants into underground drinking water supplies, according to Benjamin H. Grumbles, assistant administrator for water.
