Grain Storage Silos

[SpcFoor]

We are bidding on a project that has two areas that are going to have grain silos in them. One of them is 150'-0" tall and the other 85'. I have never done a bulk storage application like this and am trying to figure out the requirements for fire protection. Can someone point me in the right direction? I am reading NFPA 61 and 69. Any other places I need to be looking in?
