  application for such an eavesdropping or video surveillance  warrant,  a
  copy of the papers upon which the application was based must be retained
  by  the justice denying the same.  Such applications and warrants may be
  disclosed only upon a showing of good cause before a court and  may  not
  be  destroyed  except on order of the issuing or denying justice, and in
  any event must be kept for ten years.
2.  Custody of the recordings made pursuant to  subdivision  three  of
