Is it possible to trim the trees,temporarily disconnect the electrical and/or water lines and utilize a smaller rig to <br /> destroy the wells accordingly? Please provide.further.justification for your request. Regards. <br /> Lisa Medina,Senior REHS <br /> 1868 E.

The following is a list of wells that we are requesting a variance <br /> for with a description as to what the issues are. Please refer to the.attached map for well locations and utilities.
