1999 Annual Site Environmental Report
uranium, iron, total organic carbon, total
suspended solids, total dissolved solids, and
specific conductivity. The samples taken
include landfill runoff, the receiving ditch
upstream of the runoff discharge point, and the
receiving ditch downstream of the runoff
discharge point (Figure 4.2). Sampling was
performed to comply with KDWM ,requirements
for operation of the contained landfill.
Liquid Effluent Monitoring Re$ults
Analytical results are reported to KDOW in
monthly ,and quarterly discharge monitoririg
reports. Five exceedences of permit limits were
reported in 1999 for DOE Outfalls 001 and 017
(Table 7.1 and Section 2).
Outfall 017
Three noncompliances with KPDES
parameters were reported in 1999 at Outfall 017.
The noncompliances were for acute toxicity of
samples collected at the outfall. A TRE indicated
that the most iikely source of the toxicity was
from zinc washing off newly painted cylinders in
DOE cylinder storage yards. The painting
operation was ceased in 1998 and not resumed in
1999 because of the toxicity problems
associated with painted cylinders. More detailed
information is available in Section 2.
Additional data is provided in Appendix C.
Outfall 001
Two noncompWmces with KPDES
paraQ1eters were reported in 1999 at Outfall 00 1.
The noncompliances were for chronic toxicity of
samples collected at the outfall. A TRE showed
the toxicity to be from a fish pathogen (Section
2).
