As a dispatcher in CMC, I'm a little confused by Sea Isle's fire

Sea Isle City - As a dispatcher in CMC, I'm a little confused by Sea Isle's fire response now. We now have two fire chiefs for one municipality - one fire department. I believe this is the first in existence. Can someone show me in the NIMS resource typing where this exists? It's asinine - however I don't put it past Sea Isle to pull a stunt like it. They'll soon find their stunt to be short lived.
