Each county, municipality or Indian tribe served by a public transportation system which receives a service payment shall make a quarterly matching payment to the public transportation system at least equal to that portion of the section 18-b service payment received from the local assistance account of the general fund. Such matching payments shall be made not later than the 25th day of the second month of each quarter (not later than May 25, August 25, November 25, February 25). Sums so paid by the local jurisdiction shall not be used for other than the purposes of operating the public transportation systems. Additionally, the following provisions shall apply:
(a) Where more than one county or municipality is served by a regional transportation authority, the matching shares for each county or municipality are established by the Legislature by annual appropriation. Matching payments required of counties served by regional transportation authorities must be in addition to the mortgage taxes, bridge and tunnel tolls and special reduced fare programs earmarked for the regional transportation authorities and assessments paid for station maintenance, capital engineering, debt service and transit police.(b) The local match to STOA may come from any local source of revenue available to the system, other than (1) farebox or other operating revenues; (2) other per-passenger reimbursement made by a third party in lieu of fares; (3) Federal or other State funds; or (4) local funds used to match any other Federal or State programs. Revenue sharing funds, if available to a system, will be treated as local funds.N.Y. Comp. Codes R. & Regs. Tit. 17 § 975.13
