    OPINION
    AND
    ORDER OF THE
    BOARD
    (by J. Anderson):
    This matter
    conies before the Board on the February 4,
    1991
    filing of a second amended petition by the City of Oglesby
    (“Oglesby”)
    for exception to 35
    Ill. Adm. Code 306.305(a)
    and
    (b)
    of the Board’s combined sewer overflow (“CSO”) regulations.
    In
    support of its petition, Oglesby submitted Report of Monitoring
    Program to Comply with Illinois Pollution Control Board Order No.
    86-3, February 5th,
    1987,
    (September,
    1990)
    as well as a
    supplement to the report which was dated January,
    1991.1
    The
    Illinois Environmental Protection Agency
    (“Agency’t)
    filed its
    response to Oglesby’s petition on December 13,
    1991.
    (Amended
    Pet.
    Exs. B and C).
    The Agency recommends that the Board grant
    Oglesby’s request for an exception from 35 Ill.Adm. Code
    306.305(a)
    as it relates to first flush storm flows,
    and to 35
    Ill. Adm. Code 306.305(b),
    subject to conditions.
    PROCEDURAL HISTORY
    On January
    2,
    1986, Oglesby filed a petition for exception
    to 35 Ill.
    Adm. Code 306.305(a) and
    (b)
    of the Board’s CSO
    regulations.
    On February 5,
    1987, the Board granted the City of
    Oglesby (“Oglesby”)
    a temporary exception from 35 Ill. Adm. Code
    306.305(a)
    and
    (b)
    of the Board’s combined sewer overflow
    (“CSO”)
    regulations.
    Condition 2 of the February 5,
    1987 Order specified
    that the temporary exception would terminate on March
    1,
    1990,
    if
    Oglesby did not submit an amended petition for permanent
    exception on or before that date.
    The Board also required that
    Oglesby 1)
    eliminate all ponding below CSO outfalls 0—1,
    0-2,
    and
    0-3 or justify continued ponding (Condition 3(c)),
    2)
    continue
    its street sweeping program and proposed program of reducing
    infiltration and inflow,
    inspection
    of. diversion chambers, and
    construction of storm sewers
    (Condition 3(d)); and 3)
    on a
    biannual basis perform the inspections specified in 35 Iii.
    Adm.
    1For a more detailed review of the background of this case,
    please refer to the Board’s original February
    5,
    1987 Opinion and
    Order
    as well
    as
    the
    October
    15,
    1987,
    and November
    29,
    1990~
    Orders, which are hereby incorporated by reference.
    130—01

    2
    Code 306.361(a)
    and further measure and test the overflow events
    at CSO 0-1,
    0-2, and 0-3 to determine their frequency,
    extent and
    quality (Condition 3(e)).
    Because Oglesby did not submit an
    amended petition by the March
    1,
    1990 deadline, the Board
    relinquished its jurisdiction in the matter and closed the docket
    on June 7,
    1990.
    In response to the Board’s June 7,
    1990 Opinion and Order,
    Oglesby filed a Motion for Reconsideration and an Amended
    Petition on June 29,
    1990.
    In the Motion for Reconsideration and
    accompan’ying Amended Petition, Oglesby requested the Board to
    reconsider its June 7,
    1990 order, enter an order retaining
    jurisdiction, and extend its temporary exception from 35 Ill.Adm.
    Code 306.305(a)
    and
    (b)
    for nine months
    (i.e. until March
    1,
    1991),
    so that it could complete its inspections and monitoring
    and file a second amended petition for a permanent CSO exception
    pursuant to Condition
    2 of the Board’s February 5,
    1987 Order.
    Oglesby also filed its Monitoring Program Report covering
    overflow events in June,
    July, and August,
    1990 (Exhibit B).
    On November 29,
    1990, the Board vacated its June 7,
    1990
    Order that had we relinquished jurisdiction in this matter, and
    granted Oglesby a temporary exception, until February 3,
    1991,
    from 35 111. Adm. Code 306.305(a)
    and from 35 Ill.
    Adni.
    Code
    306.305(b).
    The Board also required that Oglesby
    1)
    inspect the
    ravines blow all outfalls for ponding at least once and, with the
    exception of CSO 0-4,
    eliminate all ponding or justify in its
    amended petition that elimination is technically infeasible or
    economically unreasonable (Condition 3(c));
    2) inspect.below the
    outfalls at least once for unnatural bottom deposits, odors,
    unnatural floating material or color, stream morphology,
    and
    results of limited stream chemical analysis; and
    3) measure that
    test overflows at CSO outfalls 01,
    02, and 03
    (condition 3(e)).
    In making this ruling we assumed that the Agency agreed to
    Oglesby’s monitoring program and that the Agency would be
    reviewing Oglesby’s data during the extension.
    We asked the
    Agency to notify us within 30 days, via a Motion for
    Reconsideration,
    if this understanding is incorrect.
    If,
    on the
    other hand, the Agency did agree to the monitoring program, we
    asked
    it notify the Board if the date by which it will complete
    its review of the data was not compatible with the November 29,
    1990 Order.
    As previously stated, the Agency filed its response
    on December 13,
    1991.
    BACKGROUND
    At the June 20,
    1986 hearing in this matter, the Agency
    expressed several concerns with regard to Oglesby’s planned
    improvements to its sewerage system.
    The Agency’s concerns
    included the following:
    1.
    treatment plant hydraulic capacities upon the addition
    130=02

    3
    of one primary clarifier and one final clarifier and
    the upgrading of the trickling filter at Oglesby’s
    waste water treatment plant;
    2.
    the potential effects on overflows by an expansion of
    an area located to the west of the City near the
    intersection of Interstate Highway 39 and Oglesby Spur
    Road;
    3.
    lack of documentation to support Oglesby’s claim that
    CSO 0-5 is a tributary to a combined sewer area;
    4.
    the separation of storm water from sanitary sewage in
    the remaining combined areas of the Oglesby; and
    5.
    localized impacts, including aesthetic problems,
    at
    CSOs 0—1,
    0—2,
    0—3, and 0—3A.
    (June 20,
    1986 transcript pp.
    123—125)
    Th.e Board was also concerned with granting Oglesby a
    permanent exception.
    Accordingly,
    as previously summarized in
    part, when the Board issued its Opinion and Order in this matter
    on February 5,
    1987,
    it granted a temporary exception and
    required Oglesby to comply with the following conditions:
    1.
    comply with the provisions of 35
    Ill.
    Adni.
    Code
    306.361(b)
    and
    (c) or justify the inapplicability of
    the required evaluations
    (Condition 3(a);
    2.
    unless authorized by the Board,
    forego expansion of the
    service area tributary to the combined sewers except
    for residential hookups that do not exceed
    15
    population equivalents
    (Condition 3(b)
    )2;
    3.
    eliminate all ponding below CSO 0—1,
    0-2,
    and 0-3 or
    justify the continued ponding (Condition 3(c));
    4.
    continue the street sweeping program and proposed
    program of reducing infiltration and inflow,
    inspection
    of diversion chambers, and construction of storm sewers
    (Condition 3(d)); and
    2On October
    15,
    1987,
    the Board modified this condition and
    granted authorization to Oglesby to seek,
    and the Agency to issue
    permits for, additional connections to existing sewers which serve
    the area located near the intersection of Interstate Highway 39 and
    Oglesby Spur Road,
    subject to certain conditions.

    on a biannual basis, perform the inspections specified
    in 35 Ill. Adm. Code 306.361(a)
    and further measure and
    test the overflow events at CSO 0-1,
    0—2, and 0-3 to
    determine their frequency,
    extent and quality
    (Condition 3(e)).
    Since the Board’s February 5,
    1987 Board Order, and in
    response to the Board’s and Agency’s concerns enunciated therein,
    Oglesby acquired.financing by issuing $1,800,000 in sewage
    revenue bonds for capital improvements to its sewage collection
    system a~idtreatment plant that were outlined in its original CSO
    petition.
    (Amended Pet. par.
    8,
    Ex. C).
    On May 13,
    1988,
    Oglesby initiated construction of the improvements.
    (Amended
    Pet. par.
    9).
    It completed such construction in January of 1990.
    (Amended Pet. par.
    9).
    In addition to the above improvements, Oglesby has taken the
    following action3:
    1.
    spent $180,000 to modify a’lift station and to
    construct and install a forcemain directly from the
    lift-station to the sewage treatment plant at the
    western part of the Oglesby where most of Oglesby’s
    growth is expected (Amended Pet. par. bc,
    Ex. A par.
    9B);
    2.
    constructed a lift—station and forcemain to collect and
    process the sanitary sewage through its collection
    system and avoid
    a discharge of sanitary sewage through
    CSO 0-5
    (Amended Pet. par.
    12D);
    3.
    installed storm sewers in every instance were it has
    constructed streets with combined sewers since June 20,
    1986 (Amended Pet. pars.
    1OD,
    l2D,
    Ex. A par.
    7);
    4.
    constructed bar screens at ten diversion structures
    (Amended Pet.
    par.
    11B, Ex. A par.
    5);
    5.
    accepted bids for its 1991 street construction projects
    wherein one-half mile of additional streets shall be
    reconstructed and storm sewers shall be installed to
    separate storm water an sanitary sewage along the
    streets
    (Amended Pet. pars. bE,
    12D);
    31n addition to
    the construction,
    Oglesby
    states
    that
    two
    events
    have, occurred
    since
    its
    original
    petition
    which
    have
    affected
    its sewerage
    system.
    First,
    a
    10 percent decrease
    in
    population since 1980 has caused a reduction in the quantity of dry
    weather flow.
    (Amended Pet, par.
    bOA).
    Second, NSM,
    Inc.
    a large
    volume industrial user has ceased operations.
    (Amended Pet.
    par.
    •lOB).
    130—04

    5
    6.
    accepted $129,000 in bids for the renovation of five
    lift stations, three of which have inadequate pumping
    capacity to pump excessive flow back into the sewage
    collection system and which thus, affect the amount of
    sewage directed to CSO 0-i. and two of which affect the
    amount of sewage directed to CSO 0-4 (Amended Pet.
    pars.
    bOF,
    12E);
    7.
    enacted an ordinance prohibiting the discharging of
    downspouts into sewers (Amended Pet. par.
    12D); and
    8.
    maintained its street sweeping program to remove debris
    from the streets before it enters the sewers,
    maintained its sewer cleaning program, continued its
    residential downspout inspection to prevent storm water
    from residential properties being deposited into the
    sewers, and continued its bar screen inspection program
    to clean the screens of trapped solid wastes
    (Amended
    Pet. pars.
    lOG—I,
    12E,
    Ex. A pars.
    5, 8); and
    9.
    established a plan to alleviate ponding at CSO 0-2 by
    depositing rocks or rip-rap below the outfall during
    the Spring of 1991.
    (Amended Pet. pars.
    lic,
    12E).
    As a result of the above improvements, all dry weather
    overflows at CSO 0-5 and 0-3A have been eliminated and sewage
    that was previously discharged is now collected and pumped
    through Oglesby’s sewage treatment system.
    (Amended Pet. pars.
    llA,
    l2E,
    Ex. A par.
    9A).
    In addition, all sanitary sewage from
    the west end is pumped to Oglesby’s treatment plant without
    infiltrating
    Oglesby’s sanitary sewer tributaries.
    (Amended Pet.
    pars. bC,
    l2B).
    The construction of the bar screens at the ten
    diversion structures has caused floatable solid wastes to remain
    and be processed through Oglesby’s sewage collection system and
    treatment plant and thus,
    has eliminated floatable solids from
    being discharged from the remaining CSOs.
    (Amended Pet.
    pars.
    biB,
    l2E,
    Ex. A par.
    5).
    With the exception of CSO 0-4 at
    Oglesby’s sewage treatment plant,
    only CSO 0—1,
    0-2, and 0-3
    remain.
    (Amended Pet. par.
    11C,
    Ex. A par.
    9C).
    Monitoring at
    these CSO5 indicates that the discharge from the CSO5
    is clear
    and odorless, and that there is no sludge or other deposits
    present.
    (Amended Pet. par.
    11C).
    The number of overflow events
    from CSO
    0-.,
    0-2, and 0-3 during July, August, November, and
    December 1990, were 15,
    12, and 9, respectively.
    (Amended Pet,.
    par.
    llC).
    When interpolated on an annual basis, Oglesby
    projects the yearly average number of overflow events from CSO 0—
    1,
    0-2, and 0—3, to be 36,
    28, and 21, respectively.
    (Amended
    Pet. par.
    11C).
    In addition to the above, capacity for complete treatment of
    wastewater at Oglesby’s sewage treatment plant has increased from
    .642 MGD to 1.2 MGD (approximately 100 percent).
    (Amended Pet.
    130—05

    6
    par.
    liD).
    The quality of effluent from the plant has also been
    improved to below NPDES permit requirement levels
    (i.e.
    25 mg/b
    BOD-5 and 30 mg/i suspended solids).
    (Amended Pet.
    par.
    liD).
    Specifically, the monthly average effluent concentrations of BODs
    has been reduced from 30+ mg/i to 11 mg/i and the monthly average
    effluent concentrations of TSS have been reduced fro~n30+ mg/i to
    12 mg/i.
    (Amended Pet. par.
    11D(l) and
    (2)).

    Section
    306.305
    provides as follows:
    Section
    306.305
    Treatment of Overflows and Bypasses
    All combined sewer overflows and treatment plant
    bypasses shall be given sufficient treatment to prevent
    pollution,
    or the violation of applicable water
    standards unless an exception has been granted by the
    Board pursuant to Subpart D.
    Sufficient treatment shall consist of the following:
    a)
    All dry weather flows, and the first flush of
    storm flows as determined by the Agency,
    shall
    meet the applicable effluent standards; and
    b)
    Additional flows,
    as determined by the Agency but
    not less than ten times average dry weather flow
    for the design year,
    shall receive a minimum of
    primary treatment and disinfection with adequate
    retention time; and
    C)
    Flows
    in excess of those described in subsection
    (b)
    shall be treated,
    in whole or in part,
    to the
    extent necessary to prevent accumulations of
    sludge deposits, floating debris and solids in
    accordance with 35 Ill.
    Adm. Code 302.203, and to
    prevent depression of oxygen levels; or
    d)
    Compliance with a treatment program authorized by
    the Board in an exception granted pursuant to
    Subpart D.
    While not necessarily quantified, the substantive provisions
    in the Subpart D exception procedures do express,
    cumulatively,
    the levels of justification required to support an exception to
    the rules of general applicability.
    For example, the 35 Ill.
    Adin.
    Code 305.350 states that Board decisions regarding
    exceptions from the CSO requirements of 35
    Iii.
    Adni. Code 306.305
    and 306.306 should be based on
    “.
    .
    .water quality effects, actual
    130—06

    7
    and potential stream uses,
    and economic considerations including
    those of the discharger and those affected by the discharge.”
    Moreover,
    35 Ill.
    Adm. Code 306.362 states that the justification
    those petitioners who apply for a CSO exception, but do not file
    a joint petition with the Agency,
    shall be established pursuant
    to the higher levels of 35 Ill. Adm. Code 306.361(b),
    (c), and
    (d).
    While the deadline has passed for the filing of petitions
    pursuant to the procedural mechanisms in Subpart
    D, the
    justification requirements contained in the rule remain in effect
    pursuant, to Section 28.1 of the Act.4
    ECONOMIC REASONABLENESS
    AND
    TECHNICAL FEASIBILITY
    Oglesby asserts that it has achieved substantial compliance
    with 35 Ill. Adm. Code 306.305(a)
    and
    (b)
    as well as the Clean
    Water Act and that any remaining existing overflows from its
    combined sewage system constitutes minimal impact upon the water
    quality of the ravine streams and the Vermillion River.
    (Amended
    Pet.
    par.
    13).
    It adds that more complete compliance will
    gradually be achieved if further street improvements including
    separation of the combined sewers occurs.
    (Amended Pet. par.
    13).’
    In addition, Oglesby states that full compliance with 35
    Ill.
    Adm. Code 306.305(a)
    and
    (b) would cause substantial
    economic hardship.
    (Amended Pet. par.
    13).
    AGENCY RESPONSE
    The Agency declined to be a joint petitioner in this case
    because inadequate time precluded an on—site visit and a thorough
    review of Ogiesby’s petition and supporting documentation prior
    to the petition being filed with the Board.
    (Agency Resp. par.
    8).
    However, on May 7,
    1991, the Agency did have the opportunity
    to inspect Oglesby’s four CSO outfalls.
    (Agency Resp. par.
    7).
    The Agency found that garbage had accumulated below CSO 0-1, but
    that the garbage did not appear to be of sanitary sewer origin.
    (Agency Resp. par.
    7(1)).
    The Agency estimated that CSO 0-1 was
    discharging at a rate of 0.014 MGD.
    (Agency Resp.
    par.
    7(1)).
    The Agency discovered a two-foot pool below CSO 0—2 and found
    that CSO 0-2 was discharging at a rate of 0.016 MGD, although the
    discharge was clear and there was no evidence of sludge or
    definite sewage odor.
    (Agency Resp. par.
    7(2)).
    CSO 0-3 was not
    discharging on the date of the inspection and appeared to have
    4The Board will evaluate Oglesby’s petition for exception in
    light
    of
    the
    CSO regulations
    because
    it
    specifically
    retained
    jurisdiction in the matter.
    The Board would also evaluate the
    petition
    in
    light
    of
    the CSO
    regulations
    even
    if
    it
    had
    not
    retained jurisdiction in this matter.

    been inactive for some time.
    (Agency Resp.
    par. 7(3)).
    Finally,
    the Agency observed that CSO 0-4 was discharging at a rate
    (including the STP effluent)
    of 0-65 MGD.
    (Agency Resp.
    par.
    7(4)).
    In addition, the Agency found no sludge,
    odor, or garbage
    below the outfall.
    (Agency Resp.
    par.
    7(4)).
    Based on the above findings, the Agency concludes that
    Oglesby’s CSOs are having a minimal discharge impact on the
    receiving streams.
    Although the Agency recommends that the Board
    grant Oglesby’s petition for exception,
    it recommends that the
    Board im~oseconditions.
    Specifically, the Agency requests the
    following:
    1.
    that Ogiesby provide, pursuant to 35 Ill. Adm. Code
    305.261(b), an evaluation of stream sediment analyses,
    biological surveys, and stream chemical analyses,
    or
    the justification, pursuant to 35 Ill. Adm.
    Code
    306.361(d), as to why the information is inapplicable;
    2.
    that Oglesby conduct additional sampling and monitoring
    to collect BOD, suspended solids and volatile solids
    concentration data at CSO 0-1,
    0-2,
    0—3, and 0-4 for an
    additional two years after the five lift stations have
    been renovated and the one—half mile of storm sewers
    have been constructed.5
    (The Agency notes that
    although the Board granted Oglesby a temporary
    exception so that Oglesby would have two years to
    gather “post—full operation data”, the activation
    points for CSO 0-1,
    0-2, and 0-3 have been low, the
    activation point for Cso 0-4 has not been determined,
    and that the data gathered during abbreviated
    monitoring period of July to August 1990 needs to be
    supplemented);
    3.
    that Oglesby provide recent economic or financial
    information (e.g., median household income and the
    current average sewer bill)
    and compare such
    information to the economic conditions and financial
    information in existence when Oglesby’s original
    petition was filed; and
    4.
    that Oglesby continue its sewer maintenance, street
    sweeping, and sewer downspout disconnection programs
    and provide the Agency with the details and schedules
    for the programs.
    (Agency Resp.
    pars.
    8-li).
    5The Agency notes that this condition will require Oglesby to
    purchase event—actuated samplers and monitors for each of the four
    CSO5.

    par.
    9).

    CONSISTENCY WITH FEDERAL
    LAW
    35 Ill.
    Adm. Code 306.305 implements Section 13 of the
    Illinois Environmental Protection Act (“Act”),
    ILL.
    REV.
    STAT.
    1989,
    ch.
    111½, par. 1013,
    and the Board’s water quality
    standards that were developed pursuant to the federal Clean Water.
    Act,
    33 U.S.C. 125b~’~q. No corresponding federal regulation
    exists.
    Therefore, this proposal does not conflict with federal
    law.
    Moreover, federal regulations exempt discharges from CSO
    sewer systems from the federal treatment requirements.
    As a
    result, tSO treatment facilities are regulated by the states
    rather than the federal authorities.
    BOARD
    DISCUSSION
    The Board finds that Oglesby, via its amended petition, has
    responded to the concerns that were raised by both the Agency and
    the Board at the time of Oglesby’s original petition.
    We note,
    however, that Oglesby’s past responsiveness has left much to be
    desired.
    However, at this juncture,
    it would create an undue
    hardship on Oglesby and serve little,
    if any, environmental
    purpose., if we were to deny Oglesby’s request for exception.
    Oglesby’s wastewater treatment plant and combined sewer upgrades
    have already been installed, and the data thus far indicates that
    the upgrades are having the desired effect.
    A denial of
    Oglesby’s request would only result in Oglesby having to pursue
    another compliance program
    (i.e.
    another design approach)
    in
    order to comply with 35
    Ill. Adm. Code 306.305(a) and
    (b).
    Accordingly, the Board will grant Oglesby’s request for a CSO
    exception.
    However, the Board shares the Agency’s concerns regarding
    the need for supplementation of certain data. Therefore, the
    Board will require that Oglesby,
    as a single petitioner,
    gather
    the additional data in 35
    Ill. Adm. Code 306.361(b)
    unless
    Oglesby, pursuant to 35
    Ill. Adm. Code 306.361(d),
    can provide a
    justification for its inapplicability.
    Even if this
    is an agreed
    minimal impact situation, the absence of the Agency as a co—
    petitioner triggers these provisions.
    (see Condition 8 of the
    accompanying Order).
    The Board will also require that Oglesby
    conduct additional sampling and monitoring to collect BOD,
    suspended solids, and volatile solids concentration data at each
    of its four CSO points for an additional two years after the five
    lift stations have been renovated and the one—half mile of storm
    sewers have been constructed.
    (see Conditions
    6 and 7 of the
    accompanying Order).
    If the above data does not support the assumptions
    underlying the Board’s grant of exception herein, we caution
    Oglesby that it bears the responsibility to assure that this
    grant of exception is modified if it is necessary to avoid
    violation of
    it.
    In other words,
    this grant of exception does
    130—09

    10
    not affect the enforceability of any other condition of the
    accompanying Order or any applicable statute or regulation.
    (see
    Condition 12 of the accompanying Order).
    In addition, the Board will require Oglesby to continue its
    sewer maintenance, street sweeping, and sewer downspout
    disconnection programs, and provide the Agency with the details
    and schedules for the programs.
    (see Conditions
    9 and 10 of the
    accompanying Order).
    However, the Board will not require Oglesby
    to submit updated economic information to the Agency because.
    economic considerations are no longer an underlying basis for
    evaluation of Oglesby’s cleanup.
    In other words, even if
    Oglesby’s economic situation has deteriorated since our earlier
    grant of temporary exception, the basis for the current grant of
    permanent exception is not influenced by economic conditions but
    by technical and environmental considerations.
    If we misperceive
    the Agency’s reasons for requesting, the updated economic
    information, the Agency is free to file a motion for
    reconsideration.
    Finally,
    in order to assure that Oglesby will progress with
    certain construction plans mentioned in its amended petition, the
    .Board will require Oglesby to eliminate ponding at CSO 0-2
    (see
    paragraphs lOE and 12E of Oglesby’s amended petition),
    construct
    the one—half mile of additional streets with storm sewers
    (see
    paragraphs lOE and 12D of Oglesby’s amended petition),
    and
    renovate the five lift stations referred to in paragraph 1OF of
    its amended petition.
    (see Conditions 1,
    2,
    3, and
    5 of the
    accompanying Order).
    The Board will also require Oglesby to
    continue to separate combined sewers by installing storm sewers
    whenever it constructs any streets in the future.
    (see Condition
    4 of the accompanying Order).
    This Opinion constitutes the Board’s findings of fact and
    conclusions of law in this matter.
