    OPINION AND ORDER OF THE BOARD (by G. T. Girard):
    On November 13, 1992, Cabot Corporation (“Cabot”) filed a
    petition for variance from 35 Ill. Adm. Code 730.168(d) (4) and
    “from the related requirements contained in sections I.A(5),
    I.H(30) (c) (iv), I.H(30)(f), and I.H.(30)(g) of Cabot’s
    Underground Injection Control (“UIC”) Permit”. (Pet. at 1.)’ On
    December 4, 1992, Cabot filed an amended petition with the Board.
    On February 18, 1993, the parties filed a document entitled
    “Joint Stipulation of Cabot Corporation and the Illinois
    Environmental Protection Agency”.2 On March 8, 1993, the Agency
    filed an amendment to the stipulation pursuant to a Board order
    construing the stipulation as the Agency recommendation and
    requesting more information. Hearing was waived in this
    proceeding.
    BACKGROUND
    Cabot’s facility at Tuscola, Douglas County, Illinois, is an
    inorganic chemical manufacturing plant. The facility
    manufactures fumed silicon dioxide marketed under the registered
    trademark of Cab-O-Sil. (Ain.Pet. at 2.) The facility has
    operated from 1958 to the present and employs approximately 190
    persons. (Am.Pet. at 2.) The facility is located three miles
    west of Tuscola and occupies 100 acres (Am.Pet. at 2) of sparsely
    populated rural area. (Am.Rec. at 2.)
    On site with the facility are two UIC wells permitted by the
    Agency. (Ain.Pet. at 3.) The facility currently generates
    approximately 200 gallons of hazardous waste per minute, with
    maximum injection rates of 100 gallons per minute at well 1 and

    the
    amended petition will be cited as “Am.Pet. at

    The document filed as “Joint Stipulation of Cabot
    Corporation and the Illinois Environmental Protection Agency”
    will be cited as “Rec. at

    the amendment to that document will
    be cited as “Am.Rec. at
    “.

    250 gallons per minute at well 2. (Am.Pet. at 3.)
    REQUESTED VARIANCE
    Cabot asks that a variance be granted from 35 Ill. Adm. Code
    730. 168(d) (4), which provides that:
    Casing inspection logs must be run at least once every five
    years unless the permit specifies otherwise due to well
    construction or other factors which limit the test’s
    reliability.
    Cabot also seeks a variance from permit conditions which
    provide:
    Section I.A(5) of the UIC Well No. 2 Permit, which requires
    that the tubing be replaced in March 1993 with tubing that
    is capable of withstanding annulus pressure testing at 500
    psig;
    Section I.H(30) (c) (iv) and its counterpart in Attachment B
    of the UIC Well No. 2 Permit, which require that the tubing
    be removed in March 1993 for the performance of a base
    temperature log and three post injection temperature logs;
    Section I.H(30) (f) and its counterpart in Attachment B of
    the permit, which require that the tubing be removed in
    March 1993 for the performance of a cement bond log;
    Section I.H(30) (g) and its counterpart in Attachment B of
    the permit, which require that the tubing be removed in
    March 1993 for the performance of an electromagnetic log.
    (Am.Pet. at 6.)
    AGENCY RECOMMENDATION
    As previously stated on February 18, 1993, the parties filed
    a document entitled “Joint Stipulation of Cabot Corporation and
    the Illinois Environmental Protection Agency”. The Board notes
    that it does not accept “stipulations” in variance proceedings.
    (See generally, Olin Corporation v. IEPA, 45 PCB 415 (PCB 81—117,
    February 17, 1982) and Donnelley v. IEPA, 96 PCB 166, (PCB 88-79,
    February 23, 1989).) Thus, the Board construed the filing as the
    Agency’s recommendation and directed the Agency to file
    additional information required pursuant to 35 Ill. Adm. Code
    104.180. The Agency filed the additional information in a
    document entitled “Agency Supplemental Response to Agreed
    Stipulation in Lieu of Recommendation” on March 8, 1993.
    I L~Q-O2IL4

    3
    The Agency agrees that a variance should be allowed by the
    Board with certain additional conditions. Those conditions are:
    I. That Cabot will submit a report on the first of each
    month with the following information for well number 2
    for the first fifteen (15) days of the previous month:
    (a) chart of seal pot level fluctuations (including
    both pressure and volume);
    (b) injection rate information; and
    (c) whether annulus fluid was added or deleted during
    the time.
    II. Cabot will provide representatives of the IEPA and the
    U.S. EPA with a telephone notification if, in Cabot’s
    judgment, annulus fluid is being lost in a manner
    unrelated to normal temperature fluctua~tions.
    III. Cabot will agree to replace the tubing for well number
    2 either within sixty (60) days after well number 3 is
    operational or during the 1994 facility shutdown,
    whichever is earlier.
    ARBITRARY AND UNREASONABLE HARDSHIP
    Cabot puts forth several arguments as to why complying with
    the general rule will create an arbitrary and unreasonable
    hardship. First, Cabot states that the permit for well 2
    requires that by March 16, 1993, “the tubing be removed for
    certain mechanical integrity test, and replaced with tubing
    capable of withstanding an annulus pressure test at 500 psig”.
    (Am.Pet. at 4.) Cabot indicates that the shut-down of well 2
    will prevent Cabot from having a like means of disposing of its
    waste since the capacity of well 1 is insufficient to meet the
    facility disposal requirements. (Am. Pet. at 3.) Thus, Cabot
    maintains that unless Cabot receives a variance the whole
    facility will have to shut down while the required tests and
    replacement of tubing in well 2 takes place. (Am.Pet. at 4.)
    The resulting two—week shut—down would be at “great cost” to
    Cabot. (Am.Pet. at 10.) Cabot notes that after well 3 is fully
    operational, it will be able to perform the required work on well
    2 without shutting down the plant. (Ain.Pet. at 5.)
    Second, Cabot argues that in October of 1992 mechanical
    integrity tests were run on well 2. The tests included an
    annulus pressure test, radioactive tracer survey, base
    temperature log, post—injection temperature logs and a bottom
    hole pressure test. (Am.Pet. at 5.) Cabot maintains that these
    OI~O-O2l5

    4
    tests indicate that there is no evidence of fluid movement along
    the bore hole. (Am.Pet. at 10.)
    Next, Cabot states that the United States Environmental
    Protection Agency (USEPA) amended its regulations on October 7,
    1992, such that it is no longer necessary to run a casing
    inspection log every five years. (Am.Pet. at 5-6.) Further,
    Cabot argues that the amended language adopted by the USEPA
    “recognized that it is possible to adequately test for mechanical
    integrity without removing the tubing. (Am.Pet. at 10.)
    In addition, Cabot argues that the “unnecessary removal of
    the tubing can place undue stress on the well components”
    (Am.Pet. at 10); while the postponing of the tests will pose “no
    danger to the human, plant, or animal life in the area”.
    (Ain.Pet. at 10.)
    The Agency agrees that compliance with the rule of general
    applicability would create an arbitrary and unreasonable hardship
    for Cabot under these circumstances. (Am.Rec. at 4.) The Agency
    stated that it “accepts Cabot’s representation that it would
    require an entire plant shut-down” to do the testing of well 2;
    and further, that Cabot’s shut—down would cause loss of business.
    (Am. Rec. at 4.) The Agency also agrees that the postponing of
    the tests will not pose a significant risk of harm to the public
    or the environment if the variance is granted. (Am.Rec. at 5.)
    CONSISTENCY WITH FEDERAL LAW
    As previously indicated Cabot points out that Federal
    regulations were amended on October 7, 1992. The amended
    language states:
    Casing inspection logs shall be run whenever the owner or
    operator conducts a workover in which the injection string
    is pulled, unless the Director waives this requirement due
    to the well construction or other factors which limit the
    test’s reliability, or based upon the satisfactory results
    of a casing inspection log run within the previous five
    years. The Director may require that a casing inspection
    log be run every five years, if he has reason to believe
    that the integrity of the long string casing of the well may
    be adversely affected by naturally—occurring or man—made
    events. (Ain.Pet. at 5-6.)
    Thus, Cabot maintains that granting the variance is consistent
    with federal law. (Am.Pet. at 8.) The Agency agrees that
    granting th~variance is apparently consistent with federal law.
    (Am.Rec. at 6.)

    DISCUSSION
    Cabot and the Agency agree that, at this time, compliance
    with Section 730.168(d) (4) would create an arbitrary and
    unreasonable hardship. Cabot would be required to close down its
    operations for at least two weeks. Further, Cabot as recently as
    October 1992 tested well 2 and found no indications of a breach.
    Thus, the Board finds that at this time compliance with Section
    730.168(d) (4) would create arbitrary and unreasonable hardship
    for Cabot.
    A change in the federal regulations no longer requires a
    casing inspection log to be completed every five years. Thus,
    the variance request appears to be consistent with federal law.
    In addition, the Agency agrees with Cabot that no significant
    risk of harm to the public or environment exists. Therefore, the
    Board will grant the variance from 35 Ill. Adm. Code
    730.168(d) (4). The Board notes that Section 36(b) of the Act
    limits the length of a variance to no longer than’ five years.
    Therefore, the Board will include a date specific on which the
    variance will expire.
    The Board, however, cannot grant a variance from a permit
    condition. (Illinois Power CompanY
    V.
    IEPA, 59 PCB 71 (PCB 84-
    75, July 19, 1984) and City of Mount Olive v. IEPA, 63 PCB 191
    (PCB 85-24, March 7, 1985).) Therefore, Cabot will have to seek
    modification of its permit from the Agency.

    III. Cabot shall replace the tubing for well number 2 either
    within sixty (60) days after well number 3 is
    operational or during the 1994 facility shutdown,
    whichever is earlier.
    IV. The terms of this variance shall expire no later than
    March 25, 1995.
    IT IS SO ORDERED.
    Section 41 of the Environmental Protection Act (Ill. Rev.
