209-D - Contracts for Outside Service by Volunteer Fire Departments and Companies.

§  209-d.  Contracts for outside service by volunteer fire departments
  and companies. Notwithstanding any other provision of law,  no  contract
  shall be made by a municipality or fire district whereby the services of
  a  volunteer  fire  department  or company are to be supplied outside of
  such municipality or fire district to provide (1) fire  protection,  (2)
  emergency service in case of accidents, calamities or other emergencies,
  or  (3)  general ambulance service pursuant to the provisions of section
  two  hundred  nine-b  of  this  article,  unless  such  volunteer   fire
  department  or  company  consents thereto. Any such contract may provide
  for the payment of a portion of the consideration expressed  therein  to
  such  volunteer  fire  department  or  company  to  be expended for fire
  department or  company  purposes  only.  If  the  municipality  or  fire
  district  owns  all of the fire apparatus to be used in carrying out the
  contract, the portion of the consideration which may  be  paid  to  such
  volunteer  fire  department  or company shall not exceed thirty-five per
  centum, unless a greater portion was being so paid on  March  fifteenth,
  nineteen  hundred  forty-one, under a contract entered into on or before
  that date, in which event a not greater portion than was being  paid  on
  said  date  may  be paid to such volunteer fire department or company in
  respect to any contract entered into on or after such date. No  payments
  shall  be  made to individual volunteer firefighters as compensation for
  rendering such outside service.
