Section 16. Summary action

Whenever the commissioner, after investigation,
  is of the opinion that any person is causing, engaging in or maintaining
  a  condition  or activity which in his opinion constitutes danger to the
  health of the people, and that it therefore appears to be prejudicial to
  the interests of the people to delay action for fifteen  days  until  an
  opportunity  for  a  hearing  can  be  provided  in  accordance with the
  provisions of section twelve-a of this chapter, the  commissioner  shall
  order  the  person,  including any state agency or political subdivision
  having jurisdiction, by written notice  to  discontinue  such  dangerous
  condition  or  activity  or  take certain action immediately or within a
  specified period of less than fifteen days.   As  promptly  as  possible
  thereafter,  within  not  to exceed fifteen days, the commissioner shall
  provide the person an opportunity to be heard and to present  any  proof
  that  such  condition  or  activity  does not constitute a danger to the
  health of the people.
