    OPINION
    AND
    ORDER OF THE BOARD
    (by C.A. Manning):
    This matter is before the Board on a petition for review of
    a final determination of the Illinois Environmental Protection
    Agency’s (Agency) denying a permit to petitioner, Jack Pease
    d/b/a Glacier Lake Extraction
    (GLE),
    brought pursuant to Section
    40(a)
    of the Illinois Environmental Protection Act (Act).
    (415
    ILCS 5/40(a).)
    The petition for review was filed with the Board
    on March 31,
    1995,
    and seeks reversal of the Agency’s February
    24,
    1995 decision denying GLE a non-NPDES mine-related pollution
    control permit for its sand and gravel mine located in Richmond,
    McHenry County, Illinois
    (GLE site).
    The Agency denied the
    permit on the basis that the information was insufficient
    regarding contamination ot groundwater at the site and the
    effects that the operation of the mine have on the migration of
    contaminants.
    (R.
    at
    109.1)
    A public hearing was held before the Board’s Chief Hearing
    Officer, Michael Wallace, on May 31, 1995 at the McHenry County
    Government Center in Woodstock,
    Illinois.
    Members of the public
    were present, but only one offered public comment.2 The following
    persons testified on behalf of GLE: Jack Pease, the owner of

    Thomas Hartz, an employee of Pease Construction and the permit
    manager for GLE, and Michael Tryon, laboratory director and
    president of McHenry Analytical Laboratory.
    GLE also called as
    adverse witnesses,
    Robb Layman,
    legal counsel for the Agency, and
    Bruce Yurdin, the permit reviewer of the Glacier Lake permit
    application.
    Bruce Yurdin also offered testimony on behalf of
    the
    Agency.
    At
    hearing,
    the
    hearing
    officer
    admitted
    several
    exhibits offered by petitioner includin~the deposition testimony
    of Bruce Yurdin, and several site maps.
    (See Pet. Exh.s #1-10.)
    On June 19,
    1995 both GLE and the Agency filed their post-hearing
    briefs, and on June 21,
    1995, the Board received a post-hearing
    written comment from Minard
    E. Hulse.
    For reasons more fully explained below, we hereby reverse
    the Agency’s final determination issued February 24,
    1995, and
    remand the matter to the Agency for final action consistent with
    this opinion and order.
    FINDINGS OF FACT
    Location and Operation of the Mine
    Glacier Lake sand and gravel mine is located at 7317
    Keystone Road,
    Richmond, McHenry County, Illinois.
    It was
    purchased in 1989 by Jack Pease and James Tonyan as a
    partnership, and in May,
    1994,
    Jack Pease acquired all of James
    Tonyan’s interest in the property.
    (Yurdin Dep.
    Exh. #5.) The
    Glacier Lake site has been commercially mined for sand and gravel
    since at least August,
    1990 by GLE, and prior to GLE’s ownership,
    since approximately 1945.
    (R. at 98.)
    GLE has had a permit from
    the Agency for virtually the same operation it seeks in this
    permit since l990.~
    (R. at 20-21; Tr.
    at 31,64.)
    The entire site is approximately 70 acres with eight to ten
    acres presently reclaimed and reseeded.
    (R. at
    16.)
    30 acres
    3me hearing officer did not admit the deposition transcript of Thomas
    Mcswiggen,
    an employee of the Agency, which was offered as evidence by the
    petitioner during the hearing.
    In the petitioner’s post—hearing brief, GLE
    requests that the Board admit two “statements against interest” made by
    Mcswiggen which appear in the deposition transcript.
    In response,
    on June 23,
    1995, the Agency objected to the motion to admit on the basis that it is
    inappropriate to use discovery as evidence in the form of a “statement against
    interest” especially when the deposed party was not called to testify.
    We
    agree and deny the motion to admit.
    The hearing officer’s ruling
    has
    not been
    challenged,
    and we will not allow portions of that transcript to be used as
    “evidence” when the party deposed could have been but was not called to
    testify.
    41n August 1990 the Agency issued a non-NPDES surface mining operating
    permit to James Tonyan d/b/a Glacier Lake Extraction, of which Jack Pease was
    a partner.
    (R. at 20.)
    This permit is being requested by Jack Pease d/b/a
    Glacier Lake Extraction.

    3
    are currently open and being mined.
    (Pet. at
    1.)
    25 acres of
    the site remain for further mining.
    At the current rate of
    mining, the Glacier Lake site will be mined out by the year 2001.
    However mining in the current portion of the site should be
    completed in two to three years.
    (Pr. to 20; R.
    at 98.)
    When
    mining at the site is completed, the owner expects to convert the
    property into a low-density housing development of approximately
    twenty home sites around two man-made lakes.
    (Tr. at 27-28;
    R.
    at 12.)
    Sand and gravel are mined at the site by using an
    earthmoving piece or equipment known as a “scraper”
    to
    shave—off
    surface soil or “overburden.”
    (Tr. at 50—51.)
    After the
    overburden is removed and placed elsewhere on the site,
    front-end
    loaders and backhoes are used to dig up the mined material which
    is the sand and gravel.
    The sand and gravel is washed with plain
    water and sorted according to size and stored pending shipment
    out of the site.
    No chemicals or explosives are used in the
    processing of the sand and gravel.
    Sorted material is then
    loaded into large dump trucks by the front-end loaders for
    shipment off-site.
    (Pr.
    at 49.)
    All of the operating machinery
    at the mine is powered by diesel fuel oil and each piece
    of
    equipment uses approximately 80 gallons of fuel per day.
    (Tr. at
    41—42.)
    At hearing, Thomas Hartz, a project manager for Pease
    Construction, who manages GLE’s permits, testified that GLE
    stores no fuel on the site and GLE conducts fueling of the GLE
    vehicles away from the open pit on an area that is either
    concrete or clay with greater than 100
    compaction.
    GLE also has
    a contingency plan, which includes training sessions, for dealing
    with spills should they occur.
    (Pr.
    at 40-56.)
    2.994 Operating Permit Application
    In August 1994,
    four months after Pease acquired Tonyan’s
    partnership interest, the Agency notified Pease that he should
    apply for a new permit as a 1990 operating permit was not
    transferable to Jack Pease because it was issued solely in the
    name of James Tonyan.5
    (Pr. at 31-32.)
    On behalf of GLE, Jack
    Pease submitted the permit application at issue seeking an
    operating permit on November 28,
    1994 pursuant to
    35 Ill.
    Adm.
    5The Agency takes the position that the petitioner no longer has a valid
    operating permit and it has instituted various legal actions (most of which
    are still pending and none of which are before this Board)
    in an effort to
    cause Pease to cease and desist his operations at the mine solely because of
    the permit/ownership
    issue.
    Additionally,
    Mdflenry County has also instituted
    legal action against Jack Pease regarding this issue.
    There appear to be no
    other allegations of violation of the Act at issue regarding this site other
    than for Pease’s continued operations of the site in light of the ownership
    question.
    (Tr.
    at 33—35.)

    4
    Code, Subtitle D,
    “Mine Related Water Pollution” Part 404,
    “State
    Permits”.
    (R. at 9—38.)
    The application described the project
    covered by the application as the open sand and gravel pit and
    indicated that the application was for “abandoning”.
    The
    application also attached three permitting schedules,
    one for the
    construction and opening or reopening a mine, operating the mine,
    and the abandonment of a mine.
    (R. at 14-16.)
    Though any permit
    the Agency would issue would not cover or otherwise authorize
    GLE’s future plans for construction on the site, the application
    attached reclamation plans which describe GLE’s plans to convert
    the site to a low-density housing development.
    (R.
    at 18.)
    While none of the questions on the application specifically
    request information regarding groundwater monitoring at the GLE
    site,
    the Agency’s permit application form requested certain
    information regarding water pollution at the site,
    as well as
    information regarding groundwater, waterwells and impact on local
    public water supplies.
    The application requested that the
    applicant “discuss proposed means of avoiding air,
    land and water
    pollution at this site when opening the mine.”
    (R.
    at
    14.)
    In
    response, GLE stated:
    “Any water within the mine area will remain
    contained.
    Waters will be tested quarterly both upstream and
    downstream from the pit.”
    The application also requested that CLE provide certain
    information regarding groundwater.
    GLE was asked to provide a
    list underground water resources, public water supplies, a map
    showing all private water supplies within a one-mile radius,
    location of wells within the set—back zone and supporting
    hydrogeolic data.
    The application further requested that the
    applicant discuss any affects the mine will have on water
    supplies.
    (R.
    at 15, Questions ##6-9.)
    In response, GLE provided information regarding the public
    water supplies,
    a. groundwater monitoring well map
    showing three
    groundwater wells
    (R.
    at 39), groundwater sampling data for
    rounds of sampling in April of 1993 and June of 1994
    (R. at 27-
    31), and well construction logs for three of the four groundwater
    monitoring wells located on the GLE property and for a wash plant
    well.
    (R. at 40-43.)
    GLE also provided two reports, one of
    which
    is entitled
    Groundwater Monitoring Surveillance for Tonyan
    Brothers, Inc.,
    and was compiled by McHenry Analytical Laboratory
    to explain the April 1993 sampling data, and the second report is
    a water resource inspection report by McHenry County for the GLE
    site.
    (R. at 37—38.)
    The groundwater data reports submitted to the Agency show
    roadings
    of
    Purgeable
    Organic
    carbon
    (POC)
    at
    the
    GLE site.
    Regarding the April 1993 data, the POC reading for one well
    tested is 2.887 mg/L
    (or 2887 ug/L).
    (R.
    at 36.)
    On the issue
    of POC, the McHenry Analytical Laboratory report, which
    accompanied these results, stated that:

    5
    Purgable Organic Compounds
    (sic.) (POC) are a total sum of
    Volatile
    Organic
    Compounds
    (VOC).
    These
    compounds
    are
    found
    in
    fuels
    such
    as
    gasoline or diesel fuel.
    POC5 should be
    used
    as
    an
    indicator
    of
    potential problems.
    Should POC5 be
    found,
    it is recommended
    that
    a
    volatile organic compound
    screen
    be
    performed.
    (R. at 35.)
    At
    hearing, Michael Tryon, the laboratory director and
    president of McHenry Analytical Laboratory, who prepared the
    report for GLE, testified that this paragraph was only intended
    to give gravel pit owners and operators an idea of what it was
    their groundwater was being tested for, and was not intended to
    be the sole basis upon which the Agency should determine the
    meaning of a facility’s groundwater analysis.
    (Tr. at 197.)
    (For
    additional discussion on the nature of POC,
    see infra,
    at pages
    9—12.)
    Regarding the June 28th round of sampling, the POC results
    were:
    GL#1
    -
    521
    ug/L
    GL#2
    -
    “unable
    to
    collect
    sample
    due to dry well”6
    GL#3
    388 ug/L
    GL#4
    1607 ug/L.
    (R. at 27—31.)
    The
    Agency’s
    December
    27th
    Request
    for
    Additional
    Information
    One month later, on December 27,
    1994, the Agency issued a
    letter requesting additional information from GLE.
    (R. at 69-70;
    Exh.#7.)
    The Agency asked for several categories of information;
    however, the request for additional information pertinent to this
    appeal is found at paragraph #5 of the Agency’s December 27th
    letter.
    That paragraph stated:
    The attachments to the application refer to four
    (4)
    monitoring wells installed after 1991.
    The plans for
    the site must identify the location of all wells,
    monitoring
    and
    potable,
    on
    the
    property.
    The
    results
    of the monitoring included in the application indicate
    concentrations of purgable organic carbon
    (POC)
    at
    three well from a June 28, 1994 round of sampling.
    Please provide data on the construction of the wells,
    screened and finished depth, and the possible source(s)
    of the POCs detected in the samples.
    If additional
    analyses were conducted on these samples to identify
    specific volatile organic compounds, please provide the
    results.
    6This well is
    consistently dry; therefore even though GLE submitted
    sampling data for four groundwater monitoring wells, only three of the wells
    actually have sampling results.
    (See e.g.
    It. at 27-31.)

    6
    The letter further provided that the Agency has received
    several requests to hold public hearing on this application, but
    that
    no
    decision
    had
    been
    made
    regarding
    the
    hearing.
    The
    letter
    finally stated that if the responses were adequate, the Agency
    would complete its review.
    (P.
    at 70; Exh.
    #7.)
    GLE’s
    Response
    to
    the
    Agency
    In response to the December 27th letter, Hartz
    (Tr.
    at 63)
    and Mary Bryant, GLE’s counsel, each sent Bruce lurdin letters
    dated January 11,
    1995.
    Hartz’s letter enclosed:
    (1) for a
    second time, well
    construction
    logs for the three groundwater
    wells and the wash plant well
    (see
    R.
    at 40-43 and R.
    at 77—80);
    (2) a second copy of the same map which was previously submitted
    showing three groundwater monitoring wells and the wash plant
    well (see R.
    at
    39 and R.
    at 76.);
    (3)
    a copy of the McHenry
    County Manual for Groundwater Monitoring and Protection at Earth
    Materials Extraction Sites adopted by the McHenry County Board
    (R.
    at 81-87); and
    (4) a copy of the McHenry Analytical Water
    Laboratory sampling procedures, which was also in the Agency’s
    possession as part of the groundwater sampling data.
    (See R.
    at
    1,
    2/,
    33
    and
    /5.)
    Regarding the possible sources of POC, the
    letter
    stated
    at
    paragraph
    #5:
    The well logs are enclosed.
    There are only three wells
    actually on the pit property.7
    The POCs indicated on
    the
    test
    results
    are
    found
    both
    upstream
    and
    downstream
    upgradient
    and downgradient
    from the pit with the
    upstream well producing the higher amounts of POCs.
    These results suggest that POCs originate off site from
    the upstream property.
    The POCs may potentially
    emanate from any fuels or farm chemicals used on the
    adjacent property.
    The McHenry County Health
    Department evaluate our samples every quarter.
    They
    are satisfied to date.
    (R.
    at 97—101.)
    7The Agency requested that GtE provide additional information on the
    location of
    four groundwater monitoring wells on the pit property and the
    installation logs for these wells.
    OLE only provided supplemental information
    for well nos.
    1,
    2, and 3, and offered no additional information for well #4.
    In addition to being a groundwater monitoring well, well #4 is also a drinking
    water well located within 75 feet of a rental house on the OLE property, and
    the record shows that at this well, the POC readings are the highest levels.
    At hearing,
    on behalf of CLE, Hartz explained that the inetaHation
    log
    was
    not provided for this well because none exists, and that he did not show it on
    the site map due to an oversight.
    He testified that he was not attempting to
    hide any information regarding well #4 and that the Agency did have knowledge
    of the location of this well.
    Zurdin also testified that the Agency had a
    site
    plan with
    well
    GL#4 identified
    on the map in its file (this map was
    admitted as Exhibit #10 at hearing).
    The record also shows that the Agency
    had the groundwater sampling data for this well showing the POC reading of
    1607 ugh.
    (See petitioner’s Exhibit #10, which is a site map showing all
    four wells;
    Tr.
    at 220—21.)

    7
    Bryant’s letter also addressed POC and its possible sources.
    Her
    letter
    provided:
    Monitoring
    of
    the
    near—surface
    groundwater
    over
    the
    past
    two
    years
    has
    revealed
    no
    significant water
    quality concerns,
    as Illinois EPA must know from its
    review of data submitted by Glacier Lake as well as by
    Glacier Lake’s opponents.
    The only elevated
    constituent,
    POC,
    is still very low, and it is
    consistently higher at upgraclient well No.1 than it is
    at downgradient well No. 2.~ This would suggest an
    upgradient
    source
    for the contaminant, and further
    suggests that Glacier Lake may have an attenuating
    effect
    on
    Poe, thus improving water quality at the
    nearby fen.9
    (R.
    at 97—101.)
    Neither Hartz or Bryant’s letter provided any additional
    sampling analysis of the June 28, 1994 sampling data.
    Neither
    Hartz nor Bryant submitted any analysis for volatile organic
    compounds for the June 28,
    1994 round of sampling, or for any
    other round of sampling.
    No VOC screening analysis was conducted
    at GLE’s gravel pit until arter the Agency’s final determination
    denying the permit was issued; therefore,
    no VOC screening was
    provided in GLE’s response.
    In addition to the Agency and GLE’s communication by letters
    of December 27, 1994 and January
    11,
    1995, there were several
    telephone conversation between the parties, which occurred during
    the statutory review period, and several additional letters sent
    to the Agency.
    After sending the January 11,
    1995 letters to
    the Agency, Hartz telephoned Yurdin on at least five separate
    occasions, to determine if Yurdin needed any information in
    addition to that in the January 11, 1995 responses.
    Hartz
    testified that he offered to meet,
    fax information, and do
    whatever it
    took to
    give the Agency additional information.
    (Tr.
    at 65-70.)
    In each of these phone calls, Yurdin indicated that
    he had not completed his review of the GLE file.
    (Id.; see also
    Tr. at 223—24,
    227 and Yurdin Dep. at 19—20,
    76—78, and 82.)
    In a letter dated February 13,
    1995,
    counsel for GLE
    responded to the Agency’s letter of January 25, 1995 which was
    R1fl
    Petitioners posthearing brief, GLE’s counsel clarifies
    tnat
    fler
    reference to Well No.
    “2” is incorrect.
    She states that this well should
    properly have been designated “downgradient well No.3,” and that well No.
    2
    is
    always dry.

    for
    groundwater information
    from
    the
    citizens.
    (R.
    at
    97.)
    (See
    discussion of Agency’s
    correspondence
    with
    citizens
    infra
    at
    page
    13.)
    In
    that
    letter,
    Bryant
    stated
    that
    GLE
    viewed
    a
    hearing
    as
    inappropriate
    and
    further
    offered
    that
    a
    meeting take place.
    The letter states
    that
    “GLE
    wanted
    the
    same opportunity
    ...
    to
    meet with IEPA and
    present
    Glacier
    Lake’s
    position
    ...
    that
    IEPA
    had)
    offered
    to
    parties
    who
    wish to put Glacier Lake out of business.”
    (R.
    at
    97.)
    According
    to
    GLE,
    the
    Agency
    did
    not
    respond
    to
    this
    letter.
    However,
    on
    February
    21,
    1995, Robb Layman,
    counsel for
    the Agency, spoke with GLE’s counsel.
    At hearing, Layman
    testified that he informed GLE’s counsel that a basis for the
    permit denial had already been determined and that if GLE wished
    to address the basis of the denial, a waiver of the statutory
    decision deadline would be required.
    (Tr.
    at 106-107; R.
    at
    102.)
    In response, GLE’s counsel sent another letter to the Agency
    via fax on February 22, 1995 memorializing the conversation
    between Layman and Bryant on February 21,
    1995.
    (R.
    at 102-104.)
    The letter indicates that in response to Layman, Bryant asked
    Layman what the technical grounds ror denial were, and that if
    the Agency provided her with a draft denial letter explaining the
    proposed grounds for denial, she might advise her client to agree
    to a 30—day extension of time to resolve the technical issues.
    The letter indicated that as of February 22,
    1995,
    no draft
    denial letter was sent to Bryant, and that GLE would therefore,
    not extend the 90-day statutory period for the Agency to make a
    determination.
    (R. at 102-104.)
    Also on February 22,
    1995, two days prior to the permit
    denial, Hartz called Yurdin for the fifth time to ask him’ what
    the technical concerns were at the site so that GLE could respond
    immediately and not delay issuance of the permit.
    (Tr. at 70; R.
    at 102.)
    Yurdin replied that he had not yet finished going
    through the file and that there was not adequate time left to
    meet on the permit.
    (R. at 103; Tr.
    at 70.)
    February
    24.
    1995
    Denial
    Letter
    the
    Section 39(a) Statement
    On
    February
    24,
    1995,
    the Agency issued its final permit
    denial letter regarding GLE’s permit application, which is the
    subject of the instant appeal.
    Essentially, the Agency denied
    the permit application on the basis that the information
    provided by GLE was insufficient to determine whether the permit
    would violate Sections 12 and 39 of the Act.
    In relevant part,
    the Agency’s denial letter provides:
    Insufficient data has been provided to the Agency in
    regard
    to
    the
    contamination
    of
    groundwater
    at
    the
    site
    and
    the
    effects
    that
    the
    operation
    of
    the
    pit
    will
    have
    on
    the
    migration
    of
    the
    contaminants.

    response
    of
    January
    11,
    1995.
    The
    response
    letter
    contends
    that
    the
    contaminants
    originate
    of f
    site.
    This
    contention,
    however,
    is
    not
    supported
    by
    the
    data
    contained
    in
    the
    response
    letter
    or
    in
    the

    or
    which
    directly

    the
    site,
    was
    incomplete.
    The

    data
    provided
    indicate
    contamination
    on
    and
    off
    site,
    with
    a
    higher
    concentration
    of purgable organic
    carbon
    on
    site.
    The
    Agency’s letter of December 27, 1994
    requested
    additional
    data
    in terms of
    possible
    sources of this
    contamination
    and
    additional
    analysis
    on
    these
    samples
    to
    identify
    the
    specific
    compounds
    involved.
    No
    information on these matters was provided.
    No
    additional well sampling data were submitted for
    results
    from
    samples
    taken
    prior
    to
    or
    following
    the
    June
    28,
    1994
    round
    of
    samples
    provided
    in
    the
    application.
    No information was provided concerning
    the ettect that operations at the site will have on the
    further release and migration of the contaminants.
    (R.
    at 109.)
    The Agency further provided that it would evaluate a revised
    application,
    and additionally issued a warning that it would be a
    violation of the Act to operate without a permit.
    The Indicator of Contamination:
    Puraeable Organic Carbon
    (POC)
    The only question of contamination raised in this record and
    this
    appeal
    is the Agency’s concern over what it believes to be
    an
    elevated
    level
    of
    purgeab.e
    organic carbon,
    or POC at the
    site.
    At the outset,
    it is
    important
    to
    note
    that
    there
    is
    no
    standard
    for
    POC
    set
    by
    the
    Board.
    (Tr.
    at
    138;
    Yurdin
    Dep.
    at
    24.)
    POC
    is
    not a specific constituent, but is instead
    an
    indicator
    parameter
    for
    possible presence of certain compounds,
    specifically volatile organic compounds.
    Illinois has
    no
    regulatory requirement to monitor for POC at gravel pit mines in
    the State of
    Illinois.
    (Yurdin
    Dep.
    at
    27;
    Tr.
    at
    138.)
    Though
    the Agency has the authority to require groundwater monitoring
    wells through the placement of a special condition in an
    operating permit, the Agency has not required the placement of
    monitoring wells at any mines in the State because it has not
    viewed
    such
    a measure as necessary.
    (Tr.
    at 138; Yurdin Dep.
    at
    28.) Additionally, for this gravel pit in particular, there is no
    Gtate permitting requirement or special condition requiring that
    GLE monitor groundwater for Poe or otherwise.
    GLE was not
    requested to provide groundwater information in its prior permit
    application regarding POC, other types of sampling, or on
    groundwater
    flow.

    10
    GLE
    does
    monitor
    groundwater
    quarterly
    for
    POC
    but
    does
    so
    pursuant
    to
    a
    conditional
    use
    permit
    issued by McHenry County.
    The
    county
    requires
    quarterly
    groundwater
    sampling
    for
    all
    gravel
    pit
    mines
    in
    the
    county
    to
    establish
    background
    levels
    for
    five
    parameters~
    Chlorides,
    Nitrate,
    Ammonia
    Nitrogen,
    Specific
    Conductivity, Partible
    sic
    Organic Carbons
    (POC) and pH.
    (R.
    at
    5,
    38
    and
    73.)
    The county’s groundwater
    monitoring
    manual
    states
    that
    the
    county
    monitors
    groundwater
    for
    POC
    because
    it
    “can be present in the groundwater from a number of operational
    sources, including fuel spills and motor oil leakage.”
    (R. at
    85.)
    Technically, POC is a fraction of total organic carbon
    (TOC)
    that can be removed from an aqueous solution by gas
    stripping under specified test conditions.
    Therefore POC
    represents the carbon content of all organic compounds present in
    a water or wastewater sample that volatilize within a specific
    range of temperature.
    In other words, POC is a measure of the
    carbon content of volatile organic compounds,
    or VOCS.
    Therefore, the presence of POC in groundwater indicates the
    presence of VOCs.
    However, these VOCs may or may not be
    constituents that are regulated under federal or State
    environmental programs.
    (See
    e.g. Yurdin Tr.
    at
    133_134,b0
    Tryon
    Pr. at 163.)
    VOCs may be present in the groundwater as
    a result either of
    groundwater contamination or of naturally occurring processes.
    Poe sampling may indicate the presence of VOCs in the groundwater
    which are associated with light distillates such as gasoline and
    diesel fuel.
    (Tr. at 135-36;
    see also
    Pr. at 40-52.)
    There are,
    however, other compounds which can naturally occur and be present
    in the purgeable organic carbon fraction.
    The POC result may
    also include organic acids such as humic acid, formic acid,
    fornate acetate, methane gas, trihalomethane.
    (Tr. at 166-167.)
    A
    VOC screen could conclusively
    establish
    whether
    the POC level
    was actually the result of regulated VOCs.
    Presence of Purgeable Organic Carbon at the GLE Site
    The Agency testified at hearing that its
    concern for POC at
    this site stemmed from the possibility that POC detected in the
    groundwater could indicate the presence of VOC5.
    Yurdin
    10When Bruce Yurdin first encountered the POC groundwater sampling
    results in the GLE permit application from June 28, 1994 and April,
    1993,
    he
    testified that he did not know what POC was and he further testified that he
    did not specifically research POC.
    (Tr. at 118, 122, 123,
    130-31, 137; Yurdin
    Dep.
    Tr. at 92.)
    Instead, he relied on the McHenry Analytical Laboratory
    report which stated that POC is a total sum of VOCs.
    (Tr.
    at 118; Yurdin Dep.
    32—33.))

    1.1
    testified that it is possible that fuel spills from fuel leaking
    through the soil and into the groundwater could account for the
    presence of POC.
    (Pr. at 135-136.)
    However, Hartz testified
    that GLE has never had a spill from fueling operations and such a
    situation
    appears
    unlikely given the operations of the
    site,
    since GLE stores no fuel, conducts fueling of vehicles away from
    the open pit on an area that is either concrete or clay with
    greater than 100
    compaction, and has a contingency plan which
    includes training sessions1 for dealing with spills should they
    occur.
    (Hartz,
    Tr. at 40-56.)
    On
    the issue of whether the operations of a sand and gravel
    mining operation could contribute to groundwater pollution,
    Yurdin explained in his deposition that while it is possible, he
    could cite no actual examples of this problem occurring in
    Illinois.
    He explained that when the overburden of top soil is
    stripped off, the groundwater is left in a generally vulnerable
    state and that the capacity of the remaining rock and material to
    attenuate any kind of spill or other contaminant would be at
    a
    low level.
    (Yurdin Dep. at 25.)
    However, the two examples
    offered by the Agency regarding groundwater contamination at
    a
    gravel pit had to do with extenuating circumstances being present
    at the site.
    For one gravel pit, a neighboring landfill had
    leachate problems which contributed to groundwater pollution on
    the site and at a second gravel pit, naturally occurring metals
    and other contaminants were present in the groundwater.
    (Yurdin
    Dep.
    at
    26.)
    On behalf of GLE, Tryon testified that in his experience of
    providing analysis for 15 or
    16 sand and gravel pits in McHenry
    County and conducting between 200 and 400 POC analyses (Tr.
    at
    153), the presence of POC in the groundwater does not necessarily
    correlate to a presence of regulated VOCs.
    He cited several
    examples from an Illinois State Water Survey study,
    An Assessment
    of Reqional Ground—Water Contamination in Illinois”
    where high
    POC readings were detected which, once screened for VOC5, did not
    show the presence of regulated VOCs.
    (Tr. at
    172.)12
    Based on
    his review of the ISWS study and conversations with its authors,
    Mr. Thomas 1-Joim and Michael Barcelona, and additionally on the
    Practical Handbook of Ground-Water Monitoring,
    Tryon
    testified
    that the range for total organic carbon which naturally occurs in
    aquifers is between 1 mg/i and 10 mg/i
    (Tr. at 173—74,
    194;
    Pet.
    Exh.
    #7)
    and the purgeable fraction of TOC,
    or POC,
    is between 5
    11This document was admitted at hearing as petitioner’s Exhibit #6.
    t2The two examples cited by Tryon from the study where POC level
    readings of 1.1 mg/i in a municipal drinking water well in Woodstock, Illinois
    and POC readings of 21.9 mg/i in a drinking water supply in Meredosia,
    Illinois, where at each source, there were no VOCs detected.
    (Tr. at 172;
    Pet. Exh. #6 at 15-16.)

    percent.
    (Tr.
    at
    175;
    Pet.
    Exh.
    at
    13.)
    Therefore,
    he
    opined that the naturally occurring range for POC in Illinois
    aquifers is between .05 mg/ and 5 mg/i
    (Tr.
    at 175-76) and that
    the POC levels at the GLE site are typical of the levels seen at
    similar gravel pits for which the McHenry Analytical Laboratory
    provides the laboratory analysis.
    (Tr. at l75.)’~
    Citizen Interest in the Operating Permit Application
    While
    the record in this case shows substantial citizen
    interest in the permit application submitted to the Agency GLE
    during the permit review process, the Board notes that few
    members of the public attended our hearing and only one offered a
    public comment on the record.’4
    Prior to the Agency’s receipt of
    GLE’s permit application on November 28,
    1994, the Agency
    received 25 letters all dated October 19,
    1994 from private
    citizens asking that the Agency hold a public hearing on the
    Glacier Lake permit application.
    (Pet. Not. to Supp. the Record,
    Exh. A.) One of these letters was from a McHenry County Board
    Member, and the Agency received an additional letter from a
    second member of the NcHenry County Board dated October 24,
    1994.
    Additionally, the agency received a letter on ~anuary 19, 1995
    from an Illinois State Representative.
    Each of these letters
    requested that a public hearing be held.
    (Id.)
    In response to the citizens who had written the Agency
    regarding a public hearing on the application, the Agency sent
    out a letter on January 25,
    1995 which requested specific
    information regarding groundwater quality.
    (Mot. to Supp.
    Record,
    Exh. A.)
    In response, the Agency received two letters
    from citizens, one of which was a group letter signed by 31
    residents.
    Both letters expressed the citizens’ concern for
    groundwater, and requested that GLE be required to identify the
    131n support of his opinion that regulated VOCs are not present in a
    quantity to be threat to groundwater, or to violate the Act, Tryon testified
    that the results of a VOC screening analysis conducted in March of 1995 after
    the permit denial
    letter was issued, demonstrate that even though the
    Poc
    levels
    vary from 94 to 886 ug/L, there were no VOC levels detected at the
    site.
    VOC
    screening analysis for each groundwater monitoring well was admitted
    at hearing as Petitioner’s Exh. #9 over the objection of the Agency who had
    concerns that the data was collected after the permit denial letter issued as
    was therefore, not a part of the Agency’s record.
    (Tr.
    at 213-15.)
    Since this
    information was not part of the record before the Agency, we will not consider
    this data, as this is not a
    cte
    novo review ot the Agency’s
    final,
    decision.
    (IEPA v.
    IPCB (5th Dist.
    1983)
    118 Ill. App.3d 772; 74 Ill. Dec. 158, 164.)
    141n both her comments at hearing and in her posthearing
    comments,
    Pettry expressed her opposition to issuing a permit to OLE and dissatisfaction
    with OLE’s explanation of the source of the POC readings. She believes it is
    not satisfactory to explain the source of the POC as originating off—site and
    for GLE to also state that the gravel pit may have an attenuating effect.

    source of Poe at the site, and the citizens’ belief that a public
    hearing is appropriate in this case.
    (Yurdin Dep. Exh.# 17 and
    18.)’~
    When GLE’s counsel, Bryant,
    learned of the correspondence
    between the citizens and the Agency, she sent a letter to Robb
    Layman, expressing GLE’s position that it did not favor a public
    hearing being held in this case.
    (R. at 97-99.)
    She also
    specifically requested a meeting with the Agency.
    (R.
    at 101.)
    The basis of her opposition to the public hearing was that the
    Agency did not have the authority to extend the permit review
    period in order to hold a public hearing.
    Additionally,
    in other
    letters in the record, GLE expressed a desire early on in the
    permit application process that the Agency conduct an expedited
    review if possible, based on GLE’s desire to obtain a valid
    operating permit and continue operating,
    and in order to resolve
    the outstanding concerns regarding the transfer of ownership
    issue.16
    ARGUMENTS OP THE PARTIES
    Glacier Lake Extraction
    Indicating that this case is “not an ordinary permit appeal”
    (Pet.
    Br. at 1), GLE has enumerated a litany of arguments as to
    why the permit denial was improper.
    It argues that the Agency
    did not rely on valid, technical grounds for its denial.
    Instead,
    it posits that the Agency denial was motivated in part
    by its desire to hold a public hearing during the 90-day
    statutory review time, and that the denial letter is insufficient
    and was obviously drafted at the last minute.
    More specifically,
    GLE argues that the Agency’s February permit denial letter itself
    is both technically and legally insufficient.
    Technically,
    OLE argues
    that the denial fails to provide any
    specific technical reasons, but instead merely alludes to a
    possibility of contamination at the site as a result of POC being
    present in the groundwater.
    GLE argues that the POC levels were
    not and are not a problem at the site,
    and further argues that
    t5Additionally, the record also shows that the Agency held at least
    three meetings with various citizens to discuss the GLE site prior to the
    application being filed as well as one which took place after the
    application’s submission.
    (Yurdin Dep.
    at 53—54,
    60; ~r. at 232.)
    second GLE counsel,
    Donald Stinespring, sent a letter dated January
    24,
    1995 to the Agency requesting expedited review of the permit on the basis
    that GLE had been barred from obtaining a McHenry County operating permit
    since the State had taken the position that the underlying State 1990
    operating permit was invalid due to the transfer of ownership issue and that
    such a position was putting an economic burden on several associated
    businesses.
    (R. at 90-91.)

    14
    there is no evidence which supports the Agency’s conclusion that
    there is or may be groundwater contamination as a result of
    GLE’s operation.
    GLE cites the uncontroverted testimony of its
    expert, Michael Tryon, for the proposition that all POC levels at
    this
    site are within naturally
    occurring ranges, and that the
    Agency has no technical basis to conclude that the Poe level is
    an appropriate basis for the conclusion that the groundwater is
    threatened.
    Petitioner argues that the testimony of the Agency’s
    own witness, Bruce Yurdin, indicates that the denial was based on
    mere “assumption,” as he testified that he did not initially even
    have knowledge of what POe was and he did “no research
    whatsoever” to determine whether the specific level of POC
    indicated a presence of pollutants.
    (Pet.
    Br. at 27, citing
    Yurdin Test
    Tr
    at 123.).
    Moreover, GLE argues that there is no evidence that the
    operation of the pit is having an adverse effect on the area
    groundwater or that any contaminants are migrating in or around
    the pit.
    GLE points out that the Agency requested no specific
    information about the gravel pit operations or about how the
    operations may have caused POC to be present in the groundwater.
    While Yurctin testified at hearing that POC could be present in
    groundwater due to fuel spills leaking through the soil and into
    the groundwater, GLE contends that no fuel is stored on site, nor
    is there evidence that fuel spills have occurred,
    or much less
    had an impact on groundwater.
    (Pet.
    Br. at 28-29.)
    Additionally,
    GLE asserts that the entire operation uses plain water which
    simply forces the natural sand and gravel through a series of
    screens, and no chemicals or explosives which might contribute to
    any contamination are used at the gravel pit.
    GLE also argues that the denial is based upon reasons which
    should have been better articulated by the Agency during its
    permit review process since the denial is based,
    in part,
    upon a
    lack
    of information
    that GLE claims it was not on notice that the
    Agency required,
    information that GLE claims
    it could have and
    would have provided had the Agency indicated it was necessary.
    GLE cites
    Wells Manufacturing v. IEPA,
    195 Ill. App.3d 593,
    553
    N.E.2d 1074
    (1st Dist.
    1990),
    for the proposition that the Agency
    was under a duty to let GLE know,
    in specific terms, what
    information it needed to make a decision.
    GLE contends that it
    responded to the information requests in the December 27th
    letter, and that to deny its permit on the grounds stated in the
    permit denial letter, without telling GLE what additional
    information might be required, violated due process.
    GLE argues
    that it made several offers by both telephone and letter to
    provide any additional information the Agency might need,
    and
    that the Agency did not respond,
    but instead waited until the
    last minute to make the decision to deny the permit based on
    “incomplete information.”
    More specifically, GLE argues that the information
    it

    15
    provided to the Agency in response to the December 27th request
    concerning POC (“Please provide data on
    ...
    the possible
    source(s) of the POC detected in the samples”) was sufficient.
    Likewise, GLE argues that it is not reasonable to deny the permit
    because it did not conduct VOC screening,
    since the Agency’s
    December letter stated only that “If additional analyses were
    conducted on these same samples to identify specific volatile
    organic compounds, please provide the results.”
    Since GLE had
    not conducted a
    voC
    screen, and since the Agency did not indicate
    more specifically that one was necessary, GLE argues that it was
    not under an obligation to provide such information.
    Ultimately, GLE argues that since it had no way of knowing
    that the Agency would issue a denial based on the POC results,
    it
    can not now be held responsible for failing to prove to the
    Agency that the application would violate the Act.
    While GLE was
    requested to provide possible sources of Poe, GLE asserts that it
    could not have expected or known that the Agency considered Poe
    to be a contaminant that was threatening the groundwater since
    there is no regulation or standard concerning Poe, and there are
    no procedures or criteria promulgated for the Agency’s review for
    gravel pit mining permit issuance.
    (Pet.
    Br.
    at 34.)
    Further,
    since the Agency admitted that gravel pits are not normally even
    required to test the groundwater, and GLE was not required to do
    so under its prior permit, and GLE is the only gravel pit in the
    State that has been asked to provide POC data, GLE argues that
    the Agency seeks to hold it to an
    ad hoc
    standard, which it is
    specially creating for GLE.
    (Pet. Br. at 33—34.) GLE believes
    the Agency’s denial is especially egregious under
    Wells
    Manufacturing
    in light of GLE’s repeated requests to the Agency
    to supply any further information or to hold a meeting.
    (Pet.
    sr. at 27,
    citing, Wells,
    195 111. App.3d at 597.)
    In sum, GLE maintains that the information submitted to the
    Agency during the
    permit review
    period is sufficient
    to provide
    the Agency with knowledge that no violation of the Act would
    occur if this permit had been granted.
    The
    Illinois
    Environmental
    Protection
    Agency
    In support of its final determination to deny the permit to
    GLE, the Agency argues that GLE has not met its burden of proving
    that the permit,
    as applied for to the Agency, would not violate
    the Act or the Board’s regulations.
    The Agency contends that the
    data GLE did provide shows a high level of Poc in the
    groundwater,
    that POC is indicative of possible contamination at
    the Glacier Lake facility, and that no factual information was
    provided by OLE during the Agency’s statutory review period which
    indicates that there was no contamination or that the
    contamination was “unrelated” to the mining operations.
    According to the Agency, the application and GLE’s responses to
    the Agency’s December 27th letter were missing hydrogeologic data

    16
    regarding the flow of the groundwater and information regarding
    the presence of POC and VOCs in the groundwater.
    (Agency Br. at
    6-7; Tr.
    at 142-143.) The Agency argues that at the time of its
    February 24, 1995 decision,
    it had insufficient information to
    determine whether the
    POC were originating
    ~
    or
    “on—
    site”,
    or to determine the significance of the presence of
    POC
    at
    the site.
    (Pet.
    Br.
    at
    11.)
    The Agency argues that,
    at hearing,
    it provided an adequate
    reason for having concerns regarding this site.
    Yurdin supported
    his concern for POC by testifying it is possible that POC
    contamination
    of groundwater
    could occur from gasoline or diesel
    fuel spills or leakage onto the ground, and consequently, seepage
    could take place, passing through the soil and into the
    groundwater.
    The Agency further argues that existence of POC in
    the groundwater is indicative of the presence of light
    distillates,
    including gasoline and diesel fuel, and that GLE
    never provided any data durinc~the statutory review period which
    would corroborate GLE’s argument on appeal that there is no VOC
    problem at the site.
    Regarding the VOC screen that GLE did
    provide after the permit denial and prior to hearing, the Agency
    argues that the data cannot be used as a basis to overturn the
    permit denial since the Agency was not provided with the VOC
    analysis during the permit review process.
    The Agency argues
    that the Board cannot consider information that was not before
    the Agency in making its permit denial decisions.
    Ultimately, the Agency takes the position that the
    petitioner was under an obligation to present everything
    necessary for the Agency to make a determination that the
    issuance of a permit would not violate the Act.
    The Agency
    argues it was under no obligation to request any additional
    information from the petitioner and the Agency believes that GLE
    was always free to submit any information that it felt was
    necessary
    to
    show
    that
    no
    violation would
    occur if the
    permit
    were to issue.
    Regarding the issue of communication with
    representatives of GLE, the Agency testified that it was not
    unusual for the Agency to take the entire 90-day period to make a
    decision and in this case the decision was not made until the
    90th
    day.
    RELEVANT LAW
    The Illinois Environmental Protection Act establishes a
    system or checks and balances integral to the Illinois system of
    environmental
    governance.
    Concerning the permitting function, it
    is the Agency who has the principal administrative role under the
    law.
    8pecifically, the Agency has the duty
    to establish and
    administer a permit process as required by the Act and
    regulations,
    and the Agency has the authority to require permit
    applicants to submit plans and specifications and reports
    regarding actual or potential violations of the Act, regulations

    17
    or permits.
    (Landfill,
    Inc.
    v. IPCB
    (1978)
    74 Ill.
    2d 541;
    25
    Ill. Dec.
    602,
    607
    citing,
    415
    ILCS 5/4.)
    Further, the Agency
    has the authority to perform technical,
    licensing and enforcement
    functions.
    It has the duty to collect and disseminate
    information, acquire technical data,
    and conduct experiments.
    It
    has the authority to cause inspections of actual or potential
    pollution sources and the duty to investigate violations
    of the
    Act, regulations and permits.
    (Id.
    at 606)
    Regarding permits, the Act provides that it “shall be the
    duty of the Agency to issue such a permit upon proof by the
    applicant that the facility
    ...
    will
    not cause a violation of
    this Act or of regulations hereunder.”
    When the Agency makes a
    decision to deny a permit, the Act provides that it must transmit
    to the applicant a detailed statement as to the reasons for the
    denial.
    The statement shall include, at a minimum, the sections
    of the Act or regulations which may be violated if the permit
    were granted;
    the specific type of information,
    if any, which
    the Agency deems the applicant did not provide the Agency;
    and a
    statement of specific reasons why the Act and the regulations
    would be violated if the permit were granted.
    (415 ILCS 5/39
    (a) (1)
    —(4).)
    Finally, the Act charges that the Agency “shall
    adopt such procedures as are necessary to carry out its duties
    under this the
    permitting) section.”
    (415 ILCS 5/39
    (a).)
    After the Agency’s final decision on the permit is made, the
    permit applicant may appeal that decision to the Board.
    (415
    ILCS 5/40 (a) (1).)
    The Board then holds a hearing between the
    parties at which the public may appear and offer comment.
    The
    question before the Board in a permit appeal is whether the
    applicant has met its burden of proving that issuance of the
    permit would not violate the Act.
    It is well-settled that our
    review in most types of permit appeals including this one,
    is not
    de novo but is limited to information submitted to the Agency
    during
    the
    Agency’s
    statutory
    review
    period,
    and
    not
    on
    information developed by the permit applicant,
    or the Agency,
    after the Agency’s decision.
    (See
    Alton Packaging Corporation v.
    IPCB,
    (5th Dist.
    1987)
    162 Ill. App.
    3d.
    731; 516 N.E.2d 275,
    280.)
    However,
    it is the hearing before the Board that provides
    a mechanism to the petitioner to prove that the application would
    not violate the Act.
    Further, the hearing affords the petitioner
    with the opportunity “to challenge the reasons given by the
    Agency for denying such permit by means of cross—examination and
    the Board the opportunity to receive testimony which would ‘test
    the validity or the information relied
    upon by the Agency’”
    (Alton Packaging Corporation v. IPCB
    (5th Diet.
    1989)
    162 Ill.
    App.
    3d 731;
    114 Ill. Dec.
    120,
    quoting, IEPA
    V.
    IPCB,
    115 Ill.
    2d
    at 70.)
    Under the Act,
    both the Agency
    and the Board operate
    under
    tight statutory time frames to make a decision.
    For the Agency,
    the statutory time to issue a permit decision is 90 days.
    (415

    18
    ILCS 5/39
    (a).)
    For the Board, the statutory-required time
    period is 120 days.
    During this time,
    we must hold a hearing,
    review the evidence and arguments, and make a final decision
    concerning
    the
    Agency’s
    permit decision.
    (415 ILCS 5/40
    (a) (2).)
    ANALYSIS
    It
    is
    well-established
    that
    the
    issues before the Board in a
    permit review are framed by the Agency’s denial letter.
    (See
    Centralia
    Environmental Services,
    Inc.
    v. IEPA
    (May 10,
    1990) PCB
    89-170,
    slip op. at 6.)
    We must therefore determine whether the
    stated reasons
    in
    the
    Agency’s
    February
    24,
    1995
    final decision
    to
    deny
    GLE
    an
    operating
    permit
    are
    proper.
    Those
    reasons
    are
    the Agency’s concern that the issuance of the operating permit
    might result in a violation of the Act and that it had
    insufficient information to determine whether the application as
    submitted would violate the Act or Board regulations.
    In order
    to reach a decision on the propriety of the denial letter, we
    must consider whether the petitioner has satisfied its burden of
    proving that no violation of the Act or the regulations would
    occur if the permit were to issue.
    For the following reasons we
    believe
    that
    GLE
    has in this case.
    As an initial matter, we note that the denial letter itself
    vaguely states that Section 12, the prohibitory language in the
    Act making it unlawful to contaminate the water of the State of
    Illinois, may be violated if the permit were to issue.
    (415 ILCS
    5/12.)
    While Section
    12 sets forward specific subsections
    regarding how the waters are being contaminated,
    (See Section
    12(a)—(h)), the letter itself fails to provide any explanation of
    what paragraphs
    of Section 12 might be violated by GLE’s
    operation.
    While the Agency voiced concerns that there may have
    been a fuel spill, such concerns were not raised until the
    hearing and were specifically denied by GLE.
    We nevertheless conclude that its decision to deny the
    permit because of the POC readings, was not proper.
    POC is
    merely a measurement which quantifies the carbon content of VOCs
    present in a sample.
    It does not necessarily indicate an
    exceedence of a groundwater quality standard for a regulated VOC.
    (See 35 Ill.
    Adin. Code Part 620.)
    Even after a POC test is
    performed,
    the
    POC result itself is subject to interpretation as
    to what the reading represents and, furthermore,
    there is no
    regulatory standard against which to judge whether the POC
    reading is high, low or normal.
    The Agency’s position during
    this appeal, and the position which appears to have led to its
    conclusion that the operation may be causing a violation of the
    Act,
    ic that the POC levelo may be elevated at the cite.
    We are persuaded by the testimony of GLE’s expert that the
    POC readings at this site are within naturally occurring ranges.
    GLE’s expert has reviewed between 200 and 400 POC tests in his

    19
    review
    of
    the
    groundwater
    sampling
    analysis
    for
    15 or 16 gravel
    pits in McHenry County, and he believes that it is just as likely
    that
    the
    POC
    readings
    at
    this
    site
    reflect
    the
    existence
    of
    naturally-occurring
    constituents such as humic acid (which are
    not regulated VOC5 under Part 620),
    as it is to reflect the
    presence of VOCs (which are regulated and have groundwater
    quality standards, which if exceeded would cause a violation of
    the regulations and the Act).
    Further, there is no evidence in this record that the
    operations of this site in any way caused or contributed to any
    alleged
    contamination.
    This site
    does not use any chemicals or
    explosives in
    its
    mining
    operations
    which
    would
    potentially
    cause
    groundwater contamination with VOC5.
    This is a simple operation
    whereby
    GLE
    scrapes
    of
    f earthen material, merely washes sand and
    gravel with plain water,
    and sorts the material according to the
    size of the gravel.
    While the Agency conjectures that there may
    have been a fuel spill, the petitioner specifically denies that
    any spill occurred during its operation.
    Moreover, we note that
    while there is evidence of other actions pending against GLE for
    continued operation of the site regarding the permit/ownership
    issue, none of these actions
    appear to be initiated
    by the State
    or McHenry County for violation of groundwater standards.17
    Since the Agency denial was based upon the assertion that it
    lacked the necessary information it needed to evaluate whether or
    not the permit would violate the Act, and since it would have us
    uphold its denial for GLE’s alleged failure to provide the
    information it says it wanted, we make the following comments.
    The Agency has every right, and an obligation to the people of
    the State of Illinois, to request of a permittee all information
    necessary to show that its operation will not violate the Act.
    This
    is particularly so when the Agency has sufficient reason to
    suspect that there might be a problem.
    Indeed,
    in some cases,
    particularly when the applicant seeks
    a renewal permit,
    the
    courts have also held that the Agency has an obligation to inform
    the permittee of its concerns and give notice as to what
    information
    needs
    yet
    be
    presented
    to resolve those concerns.
    (See
    e.g.
    Wells Manufacturing v. IPCB,
    195 Ill. App.
    3d 593
    (1st
    Dist.
    1990);
    Celotex Corp.
    v. IPCB
    (1983)
    94
    Ill.
    2d
    107,
    68
    Ill.
    Dec.
    108,
    445

    and Reichhold Chemicals v. IPCB

    Dist.

    207
    Ill.
    App.3d
    974,
    566
    N.E.2d
    724.)
    obviously,
    the
    Agency attempted to comply with those cases when it sent GLE the
    December letter requesting more information.
    When
    such information is requested,
    then, the permittee has
    17We also note that if the Agency discovers new evidence which leads it
    to conclude that the GLE operation
    is causing groundwater contamination in
    violation of the Act, the Agency is always free to institute an enforcement
    action pursuant to Section 12 of the Act.

    20
    the additional burden of going forward to produce the evidence
    requested
    in
    order
    to meet its burden that the permit would not
    violate the Act.
    We disagree with the Agency, however, on the
    point that GLE did not provide the information requested.
    Rather, we believe that the
    information
    provided
    by
    GLE was
    sufficient
    given
    the nature of the questions raised and the
    information solicited by the Agency.
    The Agency’s denial letter
    mischaracterizes its December request for more
    information.
    The
    denial says that letter “requested
    .
    .
    .
    additional analysis on
    these samples to identify the specific compounds involved.”
    It
    did not.
    It requested such data only “if available,” and
    arguably only concerning the June
    28,
    1994
    sampling.
    When the Agency undertakes, as is quite appropriate and
    sometimes required, to provide a permit applicant with written
    requests for more information, the Agency must carefully consider
    what it
    is that
    it is requesting.
    The Agency cannot deny a
    permit application on the basis that it lacks information which
    its earlier request
    leads
    one to reasonably conclude only needed
    to be provided “if” it was available.
    If
    the Agency had a
    serious enough concern to deny this permit as a result of the
    POe
    levels, and only a VOC screen would conclusively establish
    whether the POC number is indicative of contamination,
    it should
    not have suggested that VOC data be provided only “if available.”
    It should have required such data.
    Moreover, the evidence is uncontroverted that the Agency had
    ample
    opportunity,
    pursuant
    to
    numerous
    phone
    calls
    and
    requests
    for meetings made by GLE’s representatives, to more directly
    request the VOC sampling and have the record set straight.
    In
    factual situations such as these, where miscommunication confuses
    the
    decision-making
    process,
    promulgation
    of
    permit
    procedures
    or
    criteria
    could
    aid
    the
    permit
    review
    process.
    DECISION
    Under the facts of this case, where a mining operation has
    been active at this site for the past fifty years and has been
    permitted for at least the last five years, the mere detection of
    POC in the groundwater, which may or may not be an indication of
    contamination, does not constitute a sufficient basis for
    complete denial of the mining permit.
    This is particularly so
    under
    circumstances
    where
    the
    Agency
    has
    not
    as
    a
    general
    practice required the submittal of data concerning POC at mining
    sites, and where the Agency’s request for additional data did not
    specifically
    request
    an
    analysis of the particular regulated VOCs
    present,
    if any.
    This opinion constitutes the Board’s findings of fact and
    conclusions
    of
    law
    in
    this
    matter.
