End Further Info End Preamble Start Supplemental Information


In July 2008, EPA proposed requirements for underground injection of carbon dioxide for geologic sequestration. The proposal applies to owners or operators of wells that will be used to inject CO2 into the subsurface for the purpose of long-term storage. It proposes a new class of well (Class VI) and technical criteria for the geologic site characterization, area of review (AoR) and corrective action, well construction, operation, mechanical integrity testing, monitoring, well plugging, post-injection site care, and site closure for the purposes of protecting underground sources of drinking water.
