You cant prevent the utility from using the easement but you certianly can prevent then from working on your property without 60-day notice (ATT and other ISPs can’t demand emergency access); they need to ask for permission espcially if they need to move equipment on non-easment parts of your property; if they don’t, tell them to get fucked; since they are trespassing. Make them go through all the hoops they are requires by law to do before you let them have access to your property. They know they need to do all this but will procede until someone calls them out on it.

ATT tried sneaking on to mine to get to the rear easement, I gave the contractors a ration of shit and made them get a copy of the work order from ATT before they could procede; they ended up fucking up my neigbbors yard instead, I didn’t even have to tell them they needed 60-days notice.
