Section 179-H. Determination of appropriations against which interest payments are to be charged

Except in situations when federal law or the
  provisions of section one hundred seventy-nine-o of this article require
  otherwise, an interest payment required by this article  shall  be  paid
  from  the  same  appropriation  as  that  from  which the related proper
  invoice is paid; provided, however, (1) that the interest payment  shall
  not  reduce  the  amount  of money that otherwise will be payable to the
  contractor under the terms of the relevant contract and (2) that if  the
  obligation  to  make an interest payment is incurred in whole or in part
  because it takes the department of audit and  control  more  than  eight
  calendar  days,  excluding  legal holidays, from the date it receives an
  approvable voucher from another  state  agency  to  process  a  contract
  payment,  then  the  portion  of  the  total  interest  payment  that is
  attributable to delays by the department of audit and control  shall  be
  paid  from  funds made available to the department of audit and control.
  Notwithstanding any other provision of  law  to  the  contrary,  if  the
  amount  of  money  available  from  any  such appropriation to the state
  agency which received the proper invoice  is  insufficient  to  pay  the
  interest  and  if  for any reason it is not feasible for the director of
  the budget to exercise the transfer or interchange authority established
  by section fifty-one or ninety-three of this chapter,  the  director  of
  the  budget  may  issue  a  certificate  or certificates transferring or
  interchanging within a fund such amount as is needed to pay the interest
  to said appropriation within such fund from the unspent balance  of  any
  appropriation  that is available to the same state agency. In exercising
  the latter transfer or interchange authority, the director of the budget
  shall transfer or interchange amounts that are not needed to  accomplish
  the  purposes for which the appropriation was made, except, however, the
  director of the budget may, to  the  extent  he  deems  it  practicable,
  transfer or interchange amounts from appropriations that otherwise would
  be  available  for the administration and operations of the state agency
  which  incurred  the  interest  payment.   Any   such   certificate   or
  certificates  issued  by the director of the budget shall be sent to the
  state comptroller and copies shall be filed with  the  chairman  of  the
  senate finance committee and the chairman of the assembly ways and means
  committee.
