    OPINION
    AI~DORDER
    OF THE BOARD
    (by Mr. Young):
    This matter is before the Board on the variance petition
    filed on May
    2,
    1977, by Harvey—Ingalls Memorial Hospital
    seeking relief from Rule 602(a) of the Water Pollution Regu—
    lations.
    The Agency Recommendation favorable to the grant
    of the variance was
    filed on June
    10,
    1977.
    Rule 602(a)
    prohibits the installation of new combined sewers unless
    sufficient retention or treatment capacity is provided to
    ensure that no violation of the effluent standards occurs.
    The Petitioner
    is constructing a new professional office
    building consisting of
    a basement and three floors.
    An existing,
    but smaller, professional building on the site will be demolished.
    The new building, when fully occupied, will have approximately
    ninety employees including physicians,
    nurses and receptionists.
    The Petitioner estimates
    that
    600 patients will visit the facility
    each day and that 24,150 gallons per day of sanitary waste flow
    will be generated as a result thereof.
    Although the Agency
    states the Calumet Sewage Treatment
    Plant and the sewer system tributary to such plant have adequate
    dry weather capacity to transport and treat Petitioner’s expected
    flow,
    it is well known that overflows do occur in these systems
    during periods of wet weather.
    It
    is because of these overflows
    that Petitioner is required to seek this variance.
    The combined sewer, the subject of this petition, is
    approximately
    50 feet long and extends from Petitioner’s property
    line to the City of Harvey’s combined sewer servicing this area.
    Petitioner will maintain a storm and sanitary sewer separation
    up to arid including a manhole at its property line.
    Because
    26 —83
    —2—
    this area is presently served by
    a system of combined sewers,
    the Petitioner alleges that no useful purpose would be served
    by running parallel and separate sewers to the existing combined
    sewer system.
    As
    in Mary Ann Nowak, PCB 76-193
    (November 10,
    1976)
    and
    City of Calumet, PCB 76—318
    (February
    3,
    1977)
    the Agency submits
    that the grant of this variance will have
    a minimal environmental
    impact on the
    transport and treatment systems involved.
    The Board
    notes that the storm water which
    is generated on this site presently
    enters the combined sewer system.
    As
    in the cited cases,
    ultimate
    compliance with the regulations will
    be achieved with
    the completion
    of the MSDGC Tunnel and Reservoir Project.
    In view of the foregoing,
    the Board
    finds
    that Petiticner is
    entitled to
    relief
    from Rule 602(a)
    and the variance will be granted.
    This Opinion constitutes
    the Board’s findings of fact and
    conclusions of law in this matter.
    ORDER
    The Petitioner,
    Harvey-Ingalls ~emoria1 Hospital,
    is granted
    variance from Rule 602(a)
    to
    allow the construction of
    50 feet of
    combined sewer as more fully described in
    the petition.
    IT IS SO
    ORDERED.
    I, Christan
    L. Moffett,
    Clerk of the Illinois Pollution
    Control Board, hereby certify the above Opinion and Order were
    adopted on the
