SUPPLEMENTAL OPINION AND

ORDER

OF THE BOARD

(by D. Satchell):

On December

18, 1980 the Board granted Olin Corporation

(Olin)

a variance from the water quality standard for copper of Rule

203(f)

of Chapter

3:

Water Pollution for Olin’s discharges to

Wood River and tributaries.

On January 22,

1981 Olin filed a motion

for modification and on February 5, 1981 the Board requested addi-

tional information.

On March 23,

1981 Olin provided the requested

data.

The

Board

granted

a

variance

for

Olin’s

discharges

001

and

015.

Upon reconsideration it became apparent that Olin had re-

quested a variance for discharges 001 through 015 and that the peti-

tion had been inadequate in its description of the discharge points.

Two

separate

wastewater

systems

are

involved.

Zone

17

waste—

water

is treated in one plant which discharges via 001.

Wastewater

from Zones

1,

2,

3,

4,

5 and

7 is apparently collected for treat-

ment in the Zone

6 wastewater treatment plant, which discharges via

006

and

015.

In

addition

there

are

twelve

other

discharge

points

which

are

associated

with

the areas tributary to Zone

6.

Discharges

007,

008, Oil and 012 discharge only stormwater.

The remaining dis-

charges are combinations of stormwater, cooling water,

steam con-

densate and overflow from the system tributary to Zone

6.

The Order of December 18, 1980 is withdrawn.

This Supplemental

Opinion and Order supplements the Opinion and replaces the Order of

that date.
