ORDER OF THE BOARD
 (by J. Theodore Meyer):
This matter
 is before the Board on a joint motion to modify
a Board
 order,
 filed
 on
 February
 27,
 1990 by the City
 of
 Peru
(Peru)
 and the Illinois. Environmental Protection Agency (Agency).
Peru and the Agency ask the Board to modify its April
 1, 1987 order
which
 granted
 Peru
 a
 temporary
 exception
 from
 combined
 sewer
overflow
 (CSO)
 regulations found at
 35
 Iii.
 Adm. Code 306.305(a)
and
 (b).
 This order required Peru to file an amended petition for
permanent exception on or before March 1,
 1990, after Peru gathered
“adequate
 information”
 on
 the
 environmental
 impacts
 of
 the
overflows after Peru completed
 its proposed
 improvements
 to
 its
wastewater collection system and wastewater treatment plant.
 The
Board’s order allowed two years for gathering this information on
environmental
 impacts.
 On
 November
 19,
 1987,
 the
 Board
 granted
Peru and the Agency’s joint motion for modification and extended
the construction deadline of July 1, 1988 to November
 1,
 1989.
 The
instant
 motion
 states
 that
 Peru
 completed
 construction
 of
 the
improvements by that November 1 deadline, but points out that only
four months
 have
 passed
 since
 that
 deadline.
 Therefore,
 Peru
points out that it cannot meet the Board’s desire for two years of
information on the environmental impacts.
 Peru states that it has
diligently monitored its CSO5 and has submitted its report of that
monitoring to the Agency,
 as required by the temporary exception.
Peru also notes that the Agency desires, and Peru agrees, that Peru
will
 submit
 a plan
 of
 study
 for the CSO
 post—operational
 data
monitoring before March
 5,
 1990.
 Therefore,
 Peru and the Agency
ask the Board
 to extend the date for filing an amended petition
until November
 1,
 1991,
 to allow for the gathering of two years of
environmental information to support the amended petition.
The joint motion to modify the Board’s April
 1,
 1987 order is
granted.
 Peru shall file its amended petition for exception on or
before November
 1,
 1991.
 If the amended petition
 is not filed by
November
 1,
 1991,
 this
 temporary
 exception will
 expire
 on
 that
date.
 Additionally,
 if
 Peru
 has not
 already
 done
 so,
 Peru
 is
directed to submit its plan of study for the CSO post—operational
data monitoring to the Agency by March
 19,
 1990.
