Comment
yes Outfall 002 (rail loop pond) had
NPDES exceedance on 4/21/97
(pH 9.3 vs 9.0 limitation).
Exceedance was reported to
CWQCD within 24 hours. No
other discharges exceeded
limitations. The one-time selenium
level of 36 µg/1 reported at HGSD3
on 10/15/98 is too high for ag. use,
but no selenium standard applies.
yes
