§ 209-j. Mutual aid programs in counties. The board of supervisors in
any county may appropriate and expend such sums as it may deem necessary
and proper for the establishment and maintenance of a county mutual aid
plan in cases of fire and other emergencies in which the services of
firefighters would be used and may prescribe the method of auditing or
approving expenditures under any such appropriation. Expenses incurred
by any city, town, village or fire district participating in such mutual
aid plan shall be a lawful municipal or fire district charge to be paid
in the same manner as other like charges.
