IN THE MATTER OF:
 )
THE PETITION OF THE
 )
CITY OF LaSALLE FOR EXCEPTION
 )
 PCB 86-2
TO THE COMBINED SEWER
 )
OVERFLOW REGULATIONS
 )
ORDER OF THE BOARD
 (by J. Theodore Meyer):
This matter
 is before the Board on petitioner
 the City of
LaSalle’s
 (LaSalle) April
 15,
 1988 motion
 for modification of
 its
municipal
 compliance schedule and extension of
 the temporary
combined sewer overflow
 (CSO) exception granted by
 this Board on
April
 1,
 1987.
 The Illinois Environmental Protection Agency
(Agency) filed
 a response on May 6,
 1988.
 On May 19,
 1988 this
Board directed LaSalle
 to file
 a pleading addressing
 two issues
raised by the Agency:
 (1)
 a complete description of LaSalle’s
inability
 to meet
 its previous compliance schedule;
 and
 (2)
LaSalle’s reaction
 to the Agency’s revised compliance schedule,
which differed from the revised schedule submitted by LaSalle
 in
its April
 15,
 1988 motion.
 LaSalle filed
 its response on June
 6,
1988,
 and submitted
 a status report on August
 29,
 1988.
 The
Agency has not replied
 to either filing.
The temporary CSO exception granted by the Board on April
 1,
1987
 is effective until July
 1,
 1990
 if LaSalle
 files an amended
petition for exception on or before March
 1,
 1990.
 If no amended
petition
 is filed,
 the temporary exception expires
 on March
 1,
1990.
 In
 its instant motion for modification and extension,
 and
in
 its later
 filings,
 LaSalle seeks
 an extension of that
effective date.
 LaSalle’s request for extension
 is based
 upon a
delay in completion of
 its design plan
 for improvements
 to the
collection system and treatment plant,
 and a subsequent delay in
the start of construction
 of those improvements.
 LaSalle
maintains that these delays were caused,
 in part,
 by its
participation
 in an Illinois grant program which provided
financing for
 a portion of the project, and by LaSalle’s
 failure
to anticipate the delay between
 the public hearing
 in this matter
and the Board’s grant of
 the temporary exception.
 LaSalle states
that
 it does not seek
 to shift responsibility for
 the delays,
 but
simply wishes to explain that there were facts and developments
which were not anticipated
 in February 1986, when
 the
 initial
compliance schedule was developed.
 Thus,
 at the suggestion of
the Agency’s May 6,
 1988 response, LaSalle
 seeks modification
 of
the compliance schedule as
 follows:
93—405
—2—
Collection System
Advertise for Bids

November

July 1,
 1989
(In fact,
 LaSalle’s August
 29,
 1988 status report states
 that
LaSalle
 is slightly ahead of both of
 these schedules.)
 LaSalle
asks
 that the temporary CSO exception be extended
 to July
 1,
1991, with an amended petition due on or before March
 1,
 1991.
The two—year
 period after completion
 of the improvements
 is
 to
allow time to gather
 full operational data and make
 any necessary
corrective actions,
 as provided
 in the Board’s April
 1,
 1987
Opinion and Order.
LaSalle’s motion
 for modification and extension is granted,
with terms as set forth above.
IT IS SO ORDERED.
