OPINION AND ORDER OF THE BOARD
(by Mr. Goodman):
On May
20,
1976, Marathon Oil Company
(Marathon)
filed a
Petition for Extension of Variance before the Pollution Control
Board
(Board).
Marathon seeks a variance from Rule 206(c)
of the
Air Pollution Control Regulations
(Chapter
2)
for its fluid cata-
lytic cracking unit and its catalyst regenerator unit.
The variance
request is based upon Marathon’s installation of
a carbon monoxide
(CO) boiler to meet the 200 parts per million
(ppm)
CO standard of
Rule 206(c).
The Environmental Protection Agency
(Agency)
filed
its Recommendation on July
29,
1976.
No hearing has been held
in
this matter.
Marathon was originally granted variance
for its Robinson,
Illinois Refinery on January
9,
1975, Marathon Oil Company
V.
EPA,
PCB 74-147, and was granted an extension on December 11,
1975,
Marathon Oil Company v.
EPA, PCB 75-398.
Marathon’s operations at
the Robinson Refinery have been described in the prior Board de-
cisions.
The Agency’s Recommendation indicates that Marathon’s
present CO emissions are approximately 130,000 ppm of CO.
Marathon
processes approximately 38,000 to 40,000 barrels of gas oil per day
in its “cat cracker unit.”
Marathon is currently installing a CO
boiler
to reduce CO emission to the levels prescribed in Rule 206 (c).
The Agency believes that this CO boiler will reduce emissions to
200 ppm and thus achieve compliance with Rule 206(c).
The approxi-
mate cost of this project is $4,000,000.00.
In our Opinion of December 11, 1975, we held that the grant of
the variance would not interfere with attainment or maintenance of
23

the ambient air quality standards in the area to be affected.
The
Agency agreed with that conclusion and indicates that there has
been no change in their position.
Marathon’s petition outlines the progress it has made in imple-
menting its compliance plan and complying with the Board’s Orders.
The installation of the CO boiler has not been completed because
two turbines essential to the operation of the CO boiler have been
delayed in delivery.
The Agency’s Recommendation indicates that in
mid-July,
1976, one turbine arrived at the construction site and
is
currently being installed.
Marathon expects delivery of the second
turbine near the end of July.
The Board finds that grant of the requested variance
is justi-
fied.
The hardship on which we based our earlier decisions
in
PCB 74—147 and PCB 75—398 remains adequate to justify such a variance.
Furthermore, Marathon has shown good faith in its efforts to achieve
compliance with Rule 206(c)
as quickly as possible and has complied
with all the conditions of the prior variances,
including application
for required permits,
submission of progress reports to the Agency,
and posting of a Performance Bond in the amount of $100,000.00.
Marathon requests that variance be granted until September
30,
1976.
We
will grant the variance until that time and will retain
in effect the conditions of the earlier variances.
This Opinion constitutes the findings of fact and conclusions
of law of the Board in this matter.
ORDER
IT IS THE ORDER OF THE POLLUTION CONTROL BOARD that Petitioner
Marathon Oil Company be granted a variance from Rule
206(c) of
Chapter
2:
Air Pollution, for its Robinson, Illinois Refinery for
the period June
30,
1976 to September
30,
1976,
subject to the
conditions shown in the Board’s prior Orders in PCB 74-147 and
PCB 75—398.
