IN THE MATTER OF:

PETITION OF THE CITY OF PERU

)

PCB 86—1

FOR EXCEPTION TO COMBINED

)

SEWER OVERFLOW REGULATIONS

)

CONCURRING OPINION

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

While we fully agree that the City of Peru should receive

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

connections contained

in paragraph No.

7 of

the Order.

What the

majority has done here

is

to perhaps

inhibit major commercial,

industrial and residential developments

in Peru.

1’~hatthis 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 designed

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 Agency has singled

out

the Peru petition as the best of all the single petitioners.

The

ban was not requested by the Agency and should not have been

enacted

by the majority.
