Section 212. Responsibility; financing

1.   Unless there is in effect an
  agreement  for  federal  administration  of  additional  state  payments
  pursuant  to  section  two  hundred  eleven  of  this title, each social
  services district shall be responsible for providing  such  payments  to
  persons  who are receiving or who would but for their income be eligible
  to receive, supplemental security income benefits, and who reside or are
  found in such district, subject to supervision by the state and  subject
  to  full  reimbursement  by  the  state  of  such  payments made by such
  district. The social services districts shall also  be  responsible  for
  the  administration of the state's program of additional state payments,
  subject to reimbursement by the state in an amount equal to one-half the
  cost of such administration and shall:
    (a) accept applications for additional state payments,
    (b) determine eligibility  in  accordance  with  this  title  and  the
  regulations of the department,
    (c)  determine  the amount of the federal supplemental security income
  benefit and other countable income, and issue a grant which  when  added
  to  such  benefit  and  income  will equal such individual's standard of
  need, and
    (d) thereafter recertify eligibility periodically  as  the  department
  may require.
    2.  If  there is in effect an agreement for the federal administration
  of additional state payments, the state shall be responsible for  paying
  to  the  secretary an amount equal to: (a) the amount expended under the
  state's programs of old age assistance, assistance to the blind and  aid
  to  the disabled during the calendar year, nineteen hundred seventy-two,
  less  any  federal  funds  properly  received   on   account   of   such
  expenditures;  plus  (b)  any  amounts in addition to such sum as may be
  required by the agreement.
