let me guess:
this is about a utility easement and the power company is wanting to do something on or to the easement you are not happy with or you want to do something on the easement they will not approve.
If any of the above:
read the granting document to find out what they are allowed to do. You do not have the right to block or alter the easement in any way that would hinder their use of the easement without their approval.
