The person who holds the easement is the dominant tenant. You have no authority or power to do anything that would impede the use of the easement as granted.
There are certain circumstances where something can be done. For example if they are overburdening the easement in some way then you could take action that may result in a resolution that may allow you to address your problem. Overburdening the easement could be evidenced by drainage pipes, electric lines, sewer lines, phone lines or some other physical improvements placed by the dominant tenant on the easement that are not consistent with the use granted in the easement language.
This is just speculation on my part but it might be something to look into and go to a lawyer with.
I hope that helps.
