In partial answer to my own question, I found the following blurb on an undated NYC Council webpage, although the info seems to be about 4 years old.........
"Governor’s Island New Need. In keeping with the agreement with the federal government to assume responsibility for Governor’s Island, the Department will place on the island a brushfire team with one officer and two fire fighters to deal with any fire emergencies. In order to staff this unit for all shifts, the Department will need fifteen fire fighters. For Fiscal 2004, the Governor’s Island team will generate PS costs of $396,000 and OTPS costs of $19,000. In Fiscal 2005 and the outyears, the PS costs will be $960,000 and OTPS costs will be $46,000."
