Mr. William D. Maer appeared for Shell Oil Company;
Mr. Dale R. Turner, Assistant Attorney General, appeared for the
Environmental Protection Agency.
OPINION AND ORDER OF THE BOARD (by Mr. Duinelle):
On March 21, 1973, a variance petition was filed by Shell
asking for a variance from complying with Rule 408 of the Water
Pollution Regulations. The Agency’s recommendation, filed April
25, 1973, contained a recommendation to grant the variance. A
hearing was held on June 29, 1973.
The Wood River Refinery is located in Wood River Township,
Madison County, Illinois. It is the largest refinery located
in Illinois and has a nominal crude oil processing capacity of
260,000 barrels per day. It produces a wide range of petroleum
products that are marketed throughout the midwest. Approximately
2,000 people are employed at the refinery complex.
Shell submitted an operating permit application for the
refinery’s waste water treatment facility on September 22, 1972.
On January 11, 1973, Shell modified its permit application to show
an average effluent cyanide concentration of 0.09 mg/l instead of
0.016 mg/i. This modification occurred after testing by the
Federal Environmental Protection Agency which sampled Petitioner’s
effluent and found that it contained a higher than reported level
of cyanide.
Rule 408 of the Water Pollution Regulations sets forth a
0.025 effluent standard for cyanide dischargers effective December
31, 1973. Shell’s effluent empties into the Mississippi River
which has a dilution ratio of approximately 2300:1 when comparing
the seven-day
-
ten-year low flow to the refineryTs 6 MGD waste
water flow. Shell alleges that cyanide levels in the Mississippi
River average 0.0035 mg/i which is below the 0.01 mg/i required
for Public and Food Processing Water Supply by Rule 204 of the
Water Pollution Regulations. Petitioner seeks a variance to allow
them to discharge no more than 0.20 mg/I at any time not to exceed
0.09 as a monthly average.

Shell has stated that the cyanide discharge occurs as a waste
stream from their catalytic crackers and to force compliance with
Rule 408 on December 31, 1973 would require the discontinuance of
the cracking units with the result of shutting down the refinery.
The Agency has recommended that the Board grant the variance.
The Board finds this petition to be similar to that filed by
Texaco, PCB 73-6, decided July 19,
1973.
There, as in the present
case, Petitioner was seeking a variance from Rule 408. In Texaco
(PCB 73-6), we denied the variance from Rule 408 because the Peti-
tioner had not come forth with a program to achieve cyanide reduction.
No date was given as to the date for ultimate compliance.
The Board
was not given any commitment as to the type of cyanide control program.
Shell has not presented any time table to the Board showing
ultimate compliance, nor has it set forth what type of a program it
is going to undertake to control the problem.
Mere reference to
“laboratory investigations
are continuing” is not sufficient enough
to identify the “pig in a poke” (Texaco, 73-6).
The record has an allusion that the new Shell process for cyanide
removal may be patentable (R, 25). If this is
found to be
the case
by Shell, then the Board has non-disclosure provisions which
can be
used for protection.
In its petition, Shell states that it was in conformance with
the cyanide standard as late as April 1972. The testimony given
by a Shell witness delineates discovery of the high cyanide levels after
Federal testing in September 1972 (R. 18),
We make no judgment on the basic question of the availability
of cyanide removal technology. Once Shell reveals their promising
process both the Agency and the Board will be better able to make
that judgment.
One further comment. The computations as to the effect of the
cyanide discharges by Shell on the cyanide content of the Mississippi
River are not persuasive. The full volume of the River is not
immediately available for mixing (unless a jet diffuser is used) and
no showing is made as to the cyanide levels at the edge of the mixing
zone. This information should be supplied in aii3Tfuture proceeding.
This Opinion constitutes the findings of fact and conclusions
of law of the Board.

The Pollution Control Board denies Shell Oil’s petition for
variance without prejudice.
IT IS SO ORDERED.
