Is this temporary work space or what?
That is really wide you need professional help.
I am the first to admit I know nothing about ROW agreements....but retain the subsurface rights at all costs.
Jason......Is this pipe line considered a gathering line per your lease or an intrastate line as only in your state? Interstate pipelines, multi-states are regulated under the jurisdiction of FERC and complies with their EIS ( environmental impact statement ) policy. On this site you can go to the top search right corner and search pipeline easements. You can also go to local land groups and join ET Rover Landowners Group for discussions.
Timber is considered a crop, don't make a fast decision and sell your timber out. You can have an addendum as exhibit B incorporated in your ROW agreement that will not land-lock you from the rest of your land. You should also consider damage to the residue of remaining land.
I hope you did not negotiate your pipeline easement contract based on the opinions and comments of anonymous people on the internet. As to your current topic there is really only one smart answer, and it is the same as the only smart answer to your first topic.
Pay someone to advise you, I did when I leased my acreage for a production unit and would have had a pipeline easement ever been in question.
Please take my advice with the kindness that it was intended.
Not all attorneys are out to suck you dry. I had problems finding one who would do the things I wished him to do but eventually I found a great guy that I like very much.
And because we have him we don't have the problems that would require him, if you get my drift.
I absolutely agree with David. This ROW is enormous; they may be planning something they aren't telling you about. These agreements are complex; I've negotiated several and wouldn't dream of doing another without using my attorney every step of the way.
