Section 621. State aid; public health emergencies

If the state commissioner
  or  a  county  health  department or part-county department of health or
  municipality, with the approval of the  state  commissioner,  determines
  that  there is an imminent threat to public health, the department shall
  reimburse counties or municipalities at fifty per centum for the cost of
  emergency measures as approved by the  department  and  subject  to  the
  approval  of  the  director  of  the  budget.  Such  funds shall be made
  available from funds appropriated for public health emergencies, only to
  those counties or municipalities, which have expended  all  other  state
  aid  which  may  be  available for related activities and have developed
  measures  to  adequately  address  the   emergency.   Reimbursement   is
  conditioned  upon  availability  of  appropriated funds. For purposes of
  this section, "municipality" means a health department of a city that is
  not located in a county or part-county health district or  a  county  in
  which  the legislature has the powers and duties of a board of health of
  a county or part-county health district and cities with a population  of
  over one million persons.
