When is the last time anyone discussed Limit Lines on a football field? It's an obscure term in the rule book, but when there are serious consequences, it's brought to the forefront. Last season's Marshall vs Houston game is a prime example.
Rule 1-2-3a and b specify limit lines and Rule 1-2-8a and b deals with markers, obstructions, and safety in the playing enclosure. If there is a hazardous obstruction within the limit lines, the referee is responsible for ordering it's removal. If outside the limit lines but within the playing enclosure, the referee notifies game management. Game management has responsibility for determining corrective action.
