The new time schedule calls for start—up on December
16,
1974 and testing on January
6,
1975.
WIPCO
believes that
January
30,
1975
is a realistic date for placing the scrubber
in operation.
The Agency recommends that the Company be granted this
extension of the variance.
The EPA states “while there is
a
certain amount of dismay as a result of Petitioner~sfailure
to comply by July 31, 1974 the Agency recognizes that scrubber
technology for Petitioner~soperation has not fully evolved~
Therefore,
the Agency believes that Petitioner should not be
penalized for delays caused by changing techno1ogy~ Agency
engineers 1~elievethe additional si~xmonths requested by Petitioner
is reasonable, and that no conditions are known at the present time
to warrant a refusal of Petit~ioner~srequest.”
We agree with the Agency and shall grant the six month
extension of variance subject
to conditions imposed in our prior
Order.
This Opinion constitutes the Board~sfindings of fact and
conclusions of law.
ORDER
The variance granted to Western Illinois Power Cooperative,
Inc.
in PCB 72-441 and PCB 73-471 is extended until January
30,
1975 subject to the following conditions:
a)
WIPCO shall continue to sub~iitquarterly
reports to the Agency indicating its progress
toward completion of its control program.
b)
WIPCO shall continue to blend fuels
to
minimize emissions from the Pearl facility,
and
shall include in its quarterly reports the
types of fuel used and the percentages of
each;
and
c)
The performance bond in the amount of $250,000
which was previously ordered shall be extended
to January
30,
1975.
I, Christan L, Moffett, Clerk of the Illinois Pollution Control
Board, hereby certify the above Opinion and Order w
