re: Pipeline on farmland

Yes, limit the easement to one single pipeline.
Some pipeline companies will insist that the easement needs absurd width. They will in turn sell space for other pipelines to be placed at an amount greater than what you were paid. That assignment could will cause a liability issue. Initially the landman will say tell you BS like it (1) is necessary for proper and safe maintenance and operations and (it is the industry standard). You could grant them a temporary workspace for maintenance.

I knew a businessman in Sulphur who insisted that he was to be last to sign an pipeline agreement. He did get top dollar but my family got renewable terms based on CPI as opposed to a perpetual agreement.
