The well will be properly plugged and abandoned by setting cement plugs to isolate the Niobrara, freshwater zones, and setting a cement cap near the surface. Then the surface casing will have a plate welled as final seal 5' below the surface. The old wellbore will then be buried and the surface location will be remediated. 400591567 400591567 FORM 6 INTENT SUBMITTED 400591567.pdf 400591567 400591586 PROPOSED PLUGGING PROCEDURE H.H.
