My question involves an easement in the state of: Massachusetts. Part of my backyard is on a utility easement (electric company power lines). The powerlines are off to the side of my house and can be accessed through the front/side and backyard. I'd like to install a privacy fence with a gate around my backyard (not my front yard). Can I just install this fence without notifying the electric company since they would still be able to access the powerlines through the front/side yard or they could even walk through the gate to get into the backyard (I'm not intending to put a lock on the gate).
Thanks.
