    OPINION
    AND
    ORDER OF THE BOARD
    (by Mr. Dumelle):
    Petitioner is seeking an extension of a prior variance from
    Rule 406 of Chapter
    3:
    Water Pollution of the Board’s Rules and
    Regulations.
    (See Union Oil Company v. EPA,
    27 PCB 511, Septem-
    ber 29,
    1977).
    The Agency has recommended that the variance be
    granted subject to certain conditions.
    No hearing was held.
    Petitioner is requesting three years
    to develop a program
    which will result in compliance with Rule 406.
    In the interim
    Petitioner asks that its discharge of ammonia be limited
    to
    575
    pounds daily average and 1260 pounds daily maximum.
    These are
    the Federal BPT standards.
    Approximately two—thirds of the crude oil processed at
    Petitioner’s Chicago Refinery is “sour” and high in nitrogen.
    As ammonia controls, Petitioner has installed sour water strip-
    pers, eliminated once—through barometric condenser water, seg-
    regated its sewers, and eliminated all once-through cooling
    water.
    In addition, Petitioner has installed a waste water treat-
    ment system consisting of equalization and storm water diversion,
    API
    separators,
    primary and final clarifiers with a bottom
    settling tank, activated sludge and oxidation ponds, and a
    polishing pond.
    Petitioner has also instituted practices which
    it characterizes as
    “best available technology”.
    In 1977 these
    improvements resulted in a monthly average effluent of 16.0 mg/i
    ammonia.
    The standard for this facility is 3.0 mg/i.
    The
    principal reasons cited by Petitioner for its noncompliance are
    emergency operational problems, severe cold weather and a major
    fire caused by lightning.
    Petitioner
    is proposing to institute
    a three-pronged program of ammonia reduction which will consist
    of identifying and controlling sources of ammonia, improving
    ammonia removal facilities
    (including stripper system reliability
    and cold weather nitrification), and research through an indep-
    endent consulting firm.
    No mention is made of any plans to reduce
    the Chicago Refinery’s dependence on sour crude oil.

    Petitioner discounts the environmental impact of this
    variance because of the upstream ammonia pollution of the Chicago
    Sanitary and Ship Canal by the Metropolitan Sanitary District.
    The Agency has recommended that the term of this variance be
    limited to one year and that a written compliance program be
    submitted at the end of that period.
    The Agency points to the fact
    that Petitioner’s wastewater treatment system has not lived up to
    its design specifications and that compliance with Federal
    standards is unimportant.
    Petitioner states in its Response that its system was
    designed for an influent ammonia concentration of “virtually zero”.
    This is puzzling since the ammonia water quality in the Ship
    Canal has been known for some time.
    Petitioner states that it
    assumed greater efficiency from its strippers.
    Problems have
    arisen from the “varying nature of the
    ‘sour water’ processed”.
    Once again, no mention is made of the fact that a significant
    increase in ammonia has come from the “sour crude” processed at
    the refinery.
    Petitioner asserts that its design ammonia effluent
    concentration was “overly ambitious” since it exceeded the Fed-
    eral BPT standards.
    This reliance on Federal standards is
    misplaced since the standard in this instance
    (3.0 mg/i)
    is
    based on a strategy for achievement and maintenance of downstream
    dissolved oxygen concentrations.
    The Board has been advised of Petitioner’s problems and pro-
    gress
    in this area and agrees that denial of a variance would
    constitute an arbitrary and unreasonable hardship.
    The Board
    does not agree that three more years with no firm compliance plan
    is warranted.
    This variance shall run for two years from Septern-
    ber
    30,
    1978 with a compliance program expected by September 29,
    1980.
    This Opinion constitutes the Board’s findings of fact and
    conclusions of law in this matter.
    ORDER
    It is the Order of the Pollution Control Board that Petitioner
    be granted a variance from Rule 406 of Chapter
    3:
    Water Pollution
    of the Board’s Rules and Regulations from September 30, 1978 to
    September 29,
    1980 subject to the following conditions:
    1.
    Discharge of ammonia—nitrogen into the Ship Canal
    shall not
    exceed
    a daily average of 575 pounds and
    a daily maximum of 1,260 pounds;
    2.
    Petitioner shall continue to make a good faith
    effort to develop a program which will enable it
    to comply with Rule
    406.
    Petitioner shall continue
    31—500

    —3—
    to pursue research efforts including analysis of
    biological nitrification in various formats;
    3.
    Petitioner shall submit to the Agency bi—monthly
    progress reports on its research efforts, detailing
    with particularity what methods and systems are
    being tried or considered.
    These reports shall
    reflect the ammonia—nitrogen concentrations in
    Petitioner’s effluent discharge during the preced-
    ing two-month period;
    4.
    Petitioner shall, no later than September 29, 1980,
    provide the Agency with a written technical proposal
    and time schedule for compliance with Rule 406;
    5.
    Within 45 days after the date of the Board’s
    Order herein, the Petitioner shall execute and
    forward to the Illinois Environmental Protection
    Agency, Variance Section,
    2200 Churchill Road,
    Springfield, Illinois,
    62706,
    a Certification of
    Acceptance and Agreement to be bound to all terms
    and conditions of the variance.
    This 45 day period
    shall be held in abeyance for any period during
    which this matter is appealed.
    The form of said
    Certification shall be as follows:
