OPINION AND ORDER OF THE BOARD
(by Mr. Dumelle):
Petitioner is seeking a variance from Rules 401, 402,
404,
405,
and
406 of thapter 3:
Water Pollution for the discharge
frcm its sewage treatment facilities into Butterfield Creek.
The Agency recommended that a variance be granted.
No hearing
was held.
Petitioner
has
been
unable
to comply with the provisions
of
NPDES
Permit
No. IL0029211 for several reasons.
Hydraulic
overloads due to high, inflow
and
infiltration
in
Petitioner’s
collection system have interfered with the sewage treatment
plant’
s
ability
to
remove
BOD
and
suspended
solids
•
Present
facilities
have
never
incorpohted
ammonia
reduction.
Limita-
tions
on
chlorine
residual
and
fecal
coliform
bacteria
are.
violated
because
of
failures
of
chlorination
equipment
and
inadequate
contact
time.
Petitioner
has
also
asked
for
a
variance
from
its
present
NPDES
requirement
to
monitor
influent.
Petitioner
has
completed
a
Step 1 facilities plan under
its
construction
grant
which
will
not
be
approved
until
a
sewer
system
evaluation
survey
(SSES)
is
completed.
Petitioner’s sewage facilities handle domestic sewage
from a population of approximately 20,000.
Present facilities
include primary treatment, then secondary treatment split
between activated sludge and trickling filter processes,
followed by finishing ponds
and
chlorination.
These facili-
ties
are
designed to treat 3.5 million gallons
per
day (MGD).
Flows in excess of 4.5
MGD
receive primary treatment and
chlorination
with
reduced contact time.
When flow reaches
10.5
MGD
bypassing occurs~ During periods of little or no
inflow into the collection pystem, the average flows do not
exceed design capacity.
During March of 1979 a flow of 14.234
37—17
MGD w~srecorded,
From August 1978 until
April 1979 the
design flow was exceeded
on about 46,1
of the days in
that
period.
Effluent concentrations of BOD5 exceeded
10 mg/l on
55
of the days sampled but did not exceed
30
mg/i.
Effluent
concentrations of suspended solids exceeded
12 mg/i on 33
of
the days sampled and exceeded 30 mg/l on 2,4
of the
days
sampled.
Mass limitations in Petitioner~sNPDES permit are
exceeded more frequently due to excess
flows.
Nitrification
occurs in the activated sludge portion of Petitioner~splant
only when conditions are
favorable,
Petitioner plans
to correct its violations through com~
pletion of its SSES followed by either upgrading of its facili~
ties with construction grant funding or diversion of flows to
the Metropolitan Sanitary District of Greater Chicago
(MSD),
Presently Petitioner plans
to complete the SSES in December,
1980 and make its decision on upgrading and diversion in
January,
1981.
Petitioner~ssewer system will not be rehab~
ilitated and diversion to MSD could not occur until December,
1981,
If Petitioner~streatment facilities are upgraded,
improvements could not be completed until
May,
1984.
The
total
costs for either of these alternatives
is expected to
range from $6.4 million to $8.5 million,
Petitioner predicts no change in the present condition
of Butterfield Creek, described as “faire,
if a variance is
granted.
Petitioner points to plant improvements since
August,
1977 and increases in operation and maintenance
budgeted expenses as evidence that its present inadequate
facilities are being operated at optimum efficiency,
Petitioner feels that any more locally funded interim
improvements,
such as $600,000 capital costs
for breakpoint
chlorination for ammonia removal, would constitute undue
hardship.
Petitioner feels its resources will be better
spent pursuing long range solutions,
Petitioner has requested the following interim effluent
limitations during the variance:
~erae
~verae
BOD5
2200 lbs.
1540 lbs.
(1000 kg)/day
(700 kg)/day
(30 mg/i)
(30 mg/i)
susepnded solids
2200
lbs.
1540 lbs.
(1000 kg)/day
(700 kg)/day
(30 mg/i)
(30 mg/I)
Flow
9.0 MGD
Chlorine residual
0,2
0,75 mg/i
Fecal Coliform
unlimited when flow exceeds
4,5 MGD and
400/100 ml at other times,
Ammonia nitrogen
25 mg/i
at all times
No influent reporting requirements,
The interim relief from BOD5,
suspended solids,~flow, and
chlorine residual would be necessary only when the average
monthly flows exceed 3.5 MGD, daily flows exceed 7,0 MGD or
mean monthly temperatures are below 1°C,
Petitioner has been negotiating with MSD on diversion
since September of 1977 when it decided that this alternative
was its best long range solution,
The areawide water
quality management plan prepared by the Northeastern
Illinois Planning Commission concurs
in this decision,
Issues related to a pre~annexationagreement with MSD
presently remain unresolved,
Petitioner feels
it cannot
complete its negotiations until the SSES is completed.
In
an Amended Recommendation the Agency has asked that a
variance be granted until January
1,
1981 or until the SSES
is complete, whichever occurs first,
The Agency concprs
with Petitioner’s requested interim effluent limitations but
has indicated that no variance
is needed to drop the NPDES
requirement that influent be monitored,
The Board’s Water Pollution regulations were adopted in
1972,
The record in this matter is silent on the critical
issue of why Petitioner’s~sewagecollection and treatment
problems have lingered for over seven years with another two
to five years needed to rectify the situation,
In EPA v.
~
PCB 76—320,
26 PCB
49, June 28~i977,
the Board accepted a stipulation which provided,
inter alia,
that Petitioner would submit a facilities plan to the Agency
by June
30,
1977.
Once again the question remains
as to why
this five year delay?
In this matter, Petitioner states
that it has never provided nitrification with no explanation
why the ammonia nitrogen water quality standard of Rule
203(f) was ignored.
The Board cannot quarrel with
Petitioner’s estimated costs
if it
is required to proceed
now with local
funding for needed improvements,
The problem
remains that Petitioner has not shown why this hardship
should not be construed as self—imposed,
If Petitioner
is
inclined to~providethis information in a future variance
petition,
it should feel free to do so,
At this point the
Board sees no alternative to denying relief,
This Opinion constitutes the Board’s findings of fact
and conclusions of law in this matter,
