I've never really done something like this but I wouldn't recommend just calling their general line and asking for the plant manager. They will probably think you are just some kid who is smart enough to find out the manager's name but dumb enough to think he is actually going to take time out of his busy day to talk to you. The receptionist will probably ask who you are, probably will never have heard of you, and inform you that either the manager is in a meeting or that he doesn't take direct calls and you may send a letter. The receptionist will probably never inform the manager that you even called and then sit by the phone waiting for the next person who thinks they'll get a chance to talk to the big important guy in charge.

Instead, I think it would be better to ask to be transfered to the person in charge of community outreach and grant money allocation. Then go from there.

In any case, good luck!
