Section 229-A. Federal aid

1.  If  the  federal government, through any
  federal  law,  makes  an  allotment  of  moneys  or  otherwise  provides
  financial  aid and assistance for approved projects, the commissioner is
  hereby authorized to accept such federal moneys, aid and assistance,  to
  sign  all  necessary  agreements  therefor,  and  to  do and perform all
  necessary acts in connection therewith. The commissioner shall not enter
  into any agreement or  agreements  which  will  require  a  total  state
  contribution in excess of the amounts available for the state's share of
  the cost of such projects.
    2.  The  execution  by  the  state of any such agreement or agreements
  shall not operate or be construed to relieve the state or any town  from
  its or their obligations under the provisions of this article, except as
  hereinafter provided in this section.
    3.  The  department  of taxation and finance may accept and receive as
  custodian any and all  grants  and  money  awarded  for  assistance  for
  approved  projects  in  this state under or pursuant to any such federal
  law. All moneys so received shall be  deposited  by  the  department  of
  taxation  and  finance  in  a  special  fund  or funds and shall be used
  exclusively for the purposes of any such federal law. Such moneys  shall
  be  paid  from such fund or funds on audit of the state comptroller upon
  vouchers certified or approved by the commissioner for carrying out  the
  purposes of such federal law.
    4.  Federal aid in relation to any approved project shall be allocated
  to reduce the amount of state aid for the project and the  town's  share
  of the cost of the project in the same proportion as each is required to
  contribute  to  or  pay  for  the  portion of the cost of the project in
  relation to which state aid  may  be  paid  under  section  two  hundred
  twenty-seven of this article.
