V. EFFLUENT LL`1ITATIONS FOR THE INDUSTRL9I. WASTE'+IAT°..A DISCHAACE POLYTS:
Tab Le 6 shows the effluent limitations
for discharge points 001, 002, 003, 004,
005, 006 and 008, the sedimentation
ponds. Limitations in this table are
based on the most stringent limitations
shown is table 5 with the exception of
total iron and total suspended solids
which axe discussed in table 6. Metals
other than iron are not being limited
for the sedimentation ponds ac this time
because flaw races for the mine drainage
are unknown and because a wasceload
allocation may be needed on this segment
in the near future to balance effluent
limitations for all mines on this
segment.
