IN THE MATTER OF:

PETITION OF THE CITY OF LASALLE

)

PCB 86—2

FOR EXCEPTION FROM THE COMBINED

)

SE~EROVERFLOW REGULATIONS

)

CONCURRING OPINION

(by J. Anderson and J.D. Dumelle):

While we fully agree that the City of LaSalle should receive

this CSO exception we do not agree with the ban on new sewer

connections contained

in paragraph No.

4 of the Order.

What the

majority has done here

is

to perhaps inhibit major

commercial,

industrial

and residential developments

in LaSalle.

~hat this sewer

connection ban does is to prevent new

sanitary sewers from being hooked onto the old combined sewer

system in cases where

it

is not cost effective to run

a long

sewer main directly

to the sewage treatment plant or

through the

combined sewer

area.

Combined sewer systems, by definition, are designeá

to

handle large volumes

of water compared to dry weather

flows.

Thus,

the introduction of additional dry weather flow,

unless

extremely large,

should cause no problem at all

in dry weather

and little additional discharge during rains.

There

is nothing

in this record

to

indicate what special

concerns exist to justify this ban.

The ban was not requested

by

the Agency and should not have been enacted by the majority.
