Water: Underground Injection Control Questions and Answers on
Using the Class V Experimental Technology Well Classification
for Pilot Geologic Sequestration Projects - What is Geologic
Sequestration (GS)? - Why is EPA issuing guidance on CO2
injection? - Why are Class V wells being used for GS? - What
information does the Guidance contain? - Who should use the
Guidance? - Where can I get additional information? What is
Geologic Sequestration (GS)? Geologic sequestration, the process
of capturing carbon dioxide (CO2) from an emission source (e.g.,
a power plant) and injecting it into deep subsurface rock
formations, is part of a portfolio of technologies and technical
approaches (e.g. fuel efficiency measures, use of biomass and
alternative fuels, etc.) under consideration for reducing
Greenhouse Gas (GHG) emissions to the atmosphere. The U.S.
Department of Energy (DOE), through its Regional Carbon
Sequestration Partnerships, is sponsoring research at a number
of projects that will test the effectiveness and s
