  prospectively. BCT limitations in this rule are not applicable to
  discharges of dewatering effluent from reserve pits which as of the
  effective date of this rule no longer receive drilling fluids and
  drill cuttings. Limitations on such discharges shall be determined by
  the NPDES permit issuing authority.

  part 435, subpart A).
\3\ As determined by the presence of a film or sheen upon or a
  discoloration of the surface of the receiving water (visual sheen).
