Dear Mr. Griggs:
The phenols limitation of 27 ug/1 which would be imposed on the
J.P. Stevens - Wagram Plant effluent under the reclassification of
the Lumber River in that area as class A -II waters can be calculated
as follows:
Water quality standard for phenolic compounds in Class A -II
waters = 1.0 ug/1.
Average plant flow = 2.5 MGD = 3.875 cfs.
Seven-day ten-year low flow (design flow) in Lumber
River at discharge point = 100 cfs.
Assuming no other sources of phenolic compounds (i.e. zero
concentration) upstream of discharge point, and performing a
mass balance:
(conc. upstream) x (flow upstream) +
(conc. in effluent) x (plant flow)
(conc. downstream) x (flow downstream)
0 ug/1 x 100 cfs + x ug/1 x 3.875 cfs
= 1 ug/1 x 103.875 cfs
x = 27 ug/1
1 hope this explanation of the derivation of this phenols limit is of
help to you. If you have any further questions. please contact me or
Ms. Jennifer Zuzun of my staff.
