the Order directed

that the District and the Agency present

a timetable and cost estimates

employed while construction proceeds.

On

the following order

is hereby entered:

a

recommendation to the Board within

30 days

of receipt of the study.

If necessary,

and upon Board order,

a hearing may be held before

implementation is ordered.

The program as outlined

is

in accordance with

the position of

both parties,

the District and

the Agency.

It provides

for interim

measures to abate present violations

of the Act and the applicable

regulations.

The disastrous state

of the Lake and the Skokie drainage

ditch due to the discharges from the District was amply detailed

in

the prior opinion in this

case.

These present measures expediently

carried out should aid in alleviating the gross pollution of the

Lake before the ultimate program is completely implemented and

will

result

in the swiftest possible construction of the new sewage

treatment facilities required.

This order shall not amend or affect in any way the order of the

Board in the matter of t1~eNorth Shore Sanitary District v.
