OPINION AND ORDER OF THE BOARD
 (by Mr. Young):
On June
 8,
 1977, Petitioner filed a Motion seeking a
determination under Rule 302 in Chapter
 3:
 Water Pollution
Regulations that
 a stream known as Deep Run Creek be re-
classified as a secondary contact water.
 In
the
alternative,
Texaco submitted a variance petition requesting relief from
certain provisions of Chapter
 3:
 Water Pollution Regulations
until May
 1,
 1978.
 S~ecifica11y, a variance is requested
from Rule 203(f)
 as it applies
 to ammonia nitrogen and total
dissolved solids
 (TDS)
 and from the Rule 203(i) maximum
temperature requirements.
On June
 28,
 1977,
 the Board set this matter for hearing
following the Agency’s Objection to the variance.
 The Agency
submitted a Recommendation on July
 27,
 1977,
 and an Amended
Recommnnclation
 on
 October
 1.1
 ,
 1977,
 to
 dc~ny
 !:he
Motion
 for
Recla:~ification
 and
 to
 qrant
 the
 var~ancesub~c~
to
 certain
cond~tions.
 After
 numerous
 conL~nuances
 ~nd
L~±1~±
 Lan to waivers
of
the statutory deadline,
 a hearing was held on October 11,
1977,
 in which Petitioner withdrew its Notion to Reclassify
Deeo Run Creek and submitted its variance
 as amended by their
Response of August 29, 1977.
 During the hearing, the Agency
withdrew their Objection to the variance and both parties
stipulated to facts
 in the Petition and the Recommendation
 as
amended;
 the parties further agreed to
 a proposed plan as part
of the settlement that Petitioner construct a pumping station
to divert the wastewater discharge
 from the Deep Run Creek
into the Chicago Sanitary and Ship Canal.

The Board has held
that
 the
stipulation
 and uroposed
settlement
 between
 parties
 is
 not appropriate in
 a variance
or~ceodincc.
 Tilini Beef Packers,
 Inc., PCB 76-117
 (Sentember
2~, 1777)
.
 In this case,
 tao Board will act
 in response
 to
the F~ctiticnas amended to reflect the changes
 cit
 the hearing
and w11
 consider the Agency’s action as a recommendation
favorable
 to grant of the variance.
Petitioner owns and onerates
 a petroleum refinery which
is located on the eastern bank of the Chicago Sanitary and
Shin Canal
 in Lockport,
 Illinois.
 The refinery withdraws
an annual average of 17,132 gpm from the Ship Canal and
returns
 its once-through cooling waters
 (approrhmately 60)
to
 the Ship Canal;
 the refinery’s orocess wastewutor which
is
 treated and discharged into the Deep Run Creek,
 is the
sueject of this variance petition
 (Pet.
 p10,
 11).
Deco Run Creek
 is 3.7 miles in length and averages
 100
feet
 in width;
 dry weather flow is estimated
 as less than
972 gem.
 In the 1960’s,
 the Petitioner and others enlarged
the channel
 to allow for the increased discharges from nearby
 onerations.
 In the present form,
 the Deep Run Creek receives
overflows from the
 ILl
 inois
 and lvlichigan Canal and serves
 as
a backwater for the Sanitary
 Canal.
 At
 this
 time,
 the Deep
Ran
 Creek
 receives
 discharges
 from
 Petitioner’s
 refinery
at
 ci
 rate
 of
 4250
 ppm
 and
 from
 the
 Lockport
 Sewage
 Treatment
Plant
 at
 694
 ppm
 (Pet.
 p3,
 4,
 9).
 Accordinq
 to
 monitoring
renorts
 taken
 from
 Deep
 Run
 Creek
 downstream
 from
 the
 Texaco
discharge
 (January,
 1975,
 to January,
 1977)
,
 the
 1.5
 mg/l
ammonia nitrogen standard
 (as N) was exceeded in one—half
of
 the readings while violation of the 1000 mg/i total
dissolved solid standard occurred once during the two—year
period.
 In addition,
 the monitoring report indicates
 that
the naximum temperature water quality standard was exceeded
on four occasions during the two—year reporting period

The refinery~s
discharge
 r
 te leaves no zone of
 passage
as required by Rule 201 of Chapter
 3,
 Petitioner claims
that
 the
 mixing
 zone
 and
 zone oa passage requirements
 do
not apply to the
 treatient
 facility
 for any of the parameters.
 The Board cannot
 agrre
 Rue
 231
 of Chapter
 3 establishes
mizing
 zones to provice an adec
 ate zone of nassage for
aquatic life in
 the
 stream.
 In
 this
 matter
 ~etitioner’s
discharge
 of 4250
 ppm
 of
 the
 Deep Run Creek exceeds the
natural
 mixing zone
 boundaries
 and
 may
 thereby block any
reasonable
 zone
 of passage in violation of Rule
 201.
According to the propose1 ‘ompliance plan, the Petitioner
estimates that the constru~
 of the pumping station and
related appurtenances
 to diie~ the discharge
 to the Ship
Canal will cost $200,000
 ~
 to this Petition, the re-
finery had devoted much
 d money in efforts
 to control
air
 and waterborne
 emissc
 i
 Tn
 1970,
 Petitioner built a
sophisticated
 wastewater
 -tent plant at a cost of
 $6
million.
 In 1972,
 1t
 con’~:ncicted
 two 10-acre storm retention
ponds equipped
 with
 oil
 skimmer~
 costing
 $300,000.
 In
 efforts
to improve air quali~i,
 the
 retlnery has installed a Sulfur
Recovery Unit witi
 T,~r1 Gas
 Treating costing in excess of
$2.6 million and
 ~)
 boilers
 and electrostatic precipitators
costing $8.8 million.
 At the present time, Petitioner con-
templates additional projects
 to improve its air and water
performance at a
 cost
 of
 $1.5
 million
 (Pet.
 p26).
 Furthermore,
Petitioner has
 set
 up
 a
 water conservation and recycling plan
to reduce the
 amount
 of
 effluent discharged and to meet certain
limitations imposed by the refinery’s NPDES permit.
 This latter
program is expected to increase concentrations of ammonia nitro-
gen and TDS in the future
 (Pet.
 p14,
 15).
At the present
 time,
 the
 quality of the effluent for ammonia
nitrogen,
 TDS, and
 temperature
 is as
 follows:
1)
 The
 refinery~s
 discharge of ammonia nitro-
gen
 to
 the
 Deep Run Creek amounted to an
annual average of 201,3 kg/day
 for
 1975
which
 wa’
 reduced
 to
 112.3
 kg/day
 during
1976
 (Pe
 ,
 p14); discharge
 concentrations
for
 ammonia nitrogen
 are
 6.7 mg/l from
April to November
 and
 15.3
 mg/l
 from
December through March
 (Pet.
 Resp.
 p2,
 3).
28
 —
 373
—4-’
2)
 The dl
 charge of total dissothed solids
ranges
 from
 800
 to
 1750
 mg/i
 \~cth
 an
average of 1082 mg/i.
 Reduced flows
from the treatment facility w:~
II
 increase
concentrations
 to range between 1000 and
2100
mg/i
 (Pet.
 p15)
 with
 an
 average
 of
1500 mg/i
 (Pet.
 Resp.
 p2).
3)
 The
 temperature
 of the refinery’s discharge
to Deep Run Creek which ranges between
90°
 and
 100°F
 in
 the
 summer
 months
 and
65°
 and
 76°F
 in
 the
 remaining
 months
 is
apt to cause violations of
 th
 ambient
water temperatures of Deep Run Creek which
ranges from 33°Fto 85°during the year
(Pet.
 p15,
 16).
The Agency points out that the refinery
 is meeting the
Best Practicable Control Technology Available pursuant to the
FWPCA P.L,92-500
 as required by its NPDES permit for most of
the requirements, except that it is encountering problems
with the suspended solids and the ammonia nitrogen limits at
the same time
 (Rec.
 p14,
 15)
A biological survey to determine the condition of Deep
Run Creek downstream from the discharge was conducted by the
Agency on December 10, 1975,
 and June 15,
 1976.
 The Agency,
based on these surveys, concludes that but for Petitioner’s
present discharge,
 a diversified biota would exist
 (Rec. p5-
10).
 Additionally,
 the
 waters
 downstream
 from
 the
 discharge
contain
 sludge-like
 deposits
 which
 cause
 oil
 slicks
 when
disturbed.
If Petitioner’s proposed diversion were implemented, the
Agency claims that the diversion into the Ship Canal would meet
the applicable requirements for BOD, suspended solids, total
dissolved solids,
 temperature and mixing zone requirements of
Chapter
 3
 because
 it
 would
 then
 he
 subject
 to
 the
 less
 stringent
water
 quality
 standards
 of
 Rule
 205 for secondary contact waters.
However,
 the
 Agency believes that Petitioner’s proposed dis-
charge may violate the State effluent limits of Rule 406, Chapter
3 and Federal mass discharge limits for suspended solids
 (Rec.
p16)
Despite these shortcomings, the refinery is making head-
way toward controlling their air and water emissions.
 In light
of Petitioner’s prior efforts and the proposed plan, the Board
finds
 that to require immediate compliance with the water quality
standards
 in the Deep Run Creek would impose an arbitrary and
28
—
 374
—5—
unreasonable
 hardshth
 The Board will hereb
 grant a variance
to Petitioner from
 I
 hole
 201 zone of pass~ce requirement,
from Rule 203(f)
 as it applies
 to ammonia niTrogen and TDS,
and from the Rule 203(i) mavunum temperature
 ~quirements
 for
the
 Deep
 Run
 Creek
 until
 May
 I,
 1978.
The Board considers
 the
 prc~oseddiversion
 to
 be a
 reasonable
plan to correct the water
 qualiL1f
 problems
 in
 Deep
 Run
 Creek.
However,
 this diversion
 may be
 ocily an interim solution,
 In the
event that the Board
 reclassifica
 the Ship Canal
 as a primary
contact water, Petitioner
 will Ic required to meet these
 water
quality standards of Rule
 203.
This Opinion constitutes
 the
 Board’s
 ft~dings of fact and
conclusions of law in this
 matter.
