Carbon Capture & Seriously Need A Price On Carbon Emissions

The Environmental Protection Agency proposed a rule yesterday that would exempt carbon dioxide injected into underground carbon capture & storage (CCS) wells from regulation as hazardous waste, so long as the CO2 is held in wells designated for that purpose under the Safe Drinking Water Act. In its press release announcing the program, EPA noted that the purpose of the regulation -- as well as its prior rulemakings under the Clean Air Act to require emissions reporting by CCS facilities, and the Safe Drinking Water Act to require appropriate siting, construction and monitoring of CCS wells -- was to reduce barriers to the use of CCS and promote the technology, which has yet to be proven at a commercial scale. If the EPA is behind it, what more could CCS need?
