ORDER OF THE BOARD

(by J.D. Dumelle):

This matter comes before the Board upon the May 6,

1988,

Agency Motion To Modify Board Order.

The Motion,

not opposed by

the City of Morris

in

its May 13 filing,

identifies

a discrepancy

in completion

dates

for the Benton Street, Jefferson Street and

Pine Street storm sewer projects.

The Motion correctly notes

a conflict between Condition No.

2 of the Order and Condition No~.6,

which sets the completion

dates

for December

31,

1992.

Condition No.

2, which sets

respective completion dates

in 1989,

1989 and

1990

contains

the

correct,

agreed upon,

final, completion dates.

Accordingly the Board hereby strikes Condition No.

6 from

the Board’s Order of April

7,

1988 in PCB 86—4;

in the interests

of clarity the Board hereby sets out the Order,

as amended,

in

its entirety,
