DANVILLE SANITARY DISTRICT

Opinion and Order on Request for Additional Connections

(by

Mr.

Currie):

Our first order in this case

(May 12,

1971)

forbade new

connections

to

the sewers until interim steps were taken to

bring effluent concentrations into reasonable accord with

the

regulations.

In August,

on the basis of evidence

that those

steps

had been taken and the effluent was reasonably satisfactory,

we allowed the connection of up to

1500 new dwelling units

(August 13

,

1971).

In its report received December 3,

the

District

asks that we allow an additional

500.

We deny the

request.

The report demonstrates that the improved system worked very

well through September and early October, with BOD and suspended

solids levels often well below

20 mg/l.

Since then,

however,

results have been highly unsatisfactory, with frequent readings

above

50 and with several over 100.

The system is in bad

shape,

and

this

is

no time to add new sources.

Investigations by the District indicate that the trouble

is due

to

a doubling or tripling of the plant’s organic load

because of increased industrial discharges.

Such an increase

is not within the contemplation of our order, and steps should

be taken to abate

it.

The District has begun further investigation

to determine the cause

and is installing equipment to help

in

treating the added

load.

Until this situation

is brought under

control we cannot permit new connections.

The motion to amend the order

is hereby denied.

I,

Christan Moffett, Acting Clerk of the Pollution Control

Board, certify that the Board adopted the above Order

and

Opinion on Request for Additional Connections this__21st_day

of December,

1971 by a vote of 4~0.
