and the sediment pond discharges 001 and 006
thru 018. Monitoring Requirements are
presented on page 5 of the permit.
The permittee has submitted salinity monitor
(total dissolved solids) for the discharges
since 1977. An analysis was performed to
determine the salt contribution from dischar(
points 001 , 003, 004 and 005. Table 6 below
shows the TDS data submitted and the salt
loads resulting from this data. Salt loads
were determined as follows :
Salt Load (tons/day) = TDS (mg/l) x Flow (cfs) x .002697
TDS and flow are based on the discharge monitoring reports
