    PROPOSED RULE.
    FIRST NOTICE.
    OPINION AND ORDER OF THE BOARD
    (by J.D. Dumelle):
    SUMMARY
    OF BOARD ACTION
    The Board
    today creates
    two separate Dockets within the
    original Docket R88-30 and adopts an Order sending both subdocket
    proposals
    to first
    notice.
    Docket A proposes a new section to
    the Illinois Administrative Code which will limit
    the volatility
    of gasoline sold throughout Illinois
    to 9.5 pounds per square
    inch
    (psi)
    Reid vapor pressure
    (RVP)
    beginning with the summer of
    1990.
    Docket B proposes a similar section which further limits
    the volatility of gasoline sold in Illinois
    to 9.0 psi RVP
    beginning with the summer of
    1991.
    The Board has determined
    that
    an economic impact study
    (EcIS) need not be conducted on the
    Docket
    A proposal; however,
    the Board has determined
    that an EcIS
    should be conducted on certain limited aspects of the Docket B
    proposal.
    Because of the importance of controlling the formation
    of ozone and because of the significant reduction of ozone
    precursors resulting
    from a 9.0 psi RVP limitation,
    the Board
    requests that
    the Department
    of Energy and Natural Resources
    (DENR)
    conduct EcIS,
    but only
    if
    it can be submitted
    to the Board
    on or before June 30,
    1990.
    The Board deems
    it essential
    to have
    the EcIS by that date so that
    it can
    consider enactment
    of
    the
    rule in time for implementation during the summer of
    1991 and
    so
    that the regulated community will have ample forewarning.
    BACKGROUND
    Ozone pollution
    is one
    of the nation’s most serious and
    complex air pollution problems.
    Ozone
    is
    a photochemical oxidant
    and the major component of smog.
    Unlike other pollutants,
    ozone
    is not emitted directly into the atmosphere but
    is formed through
    chemical reactions among precursor emissions
    (volatile organic
    compounds or
    VOCs,
    nitrogen oxides,
    carbon monoxide and other
    compounds)
    in the presence of sunlight.
    The rate of ozone
    production
    is increased when atmospheric temperatures are warmer.
    103—153

    —2—
    The hot summers of 1987 and 1988 resulted in high levels of
    ozone
    in the Chicago and Metro East non—attainment areas.
    Readings as high as
    0.22
    ppm by volume were recorded, which
    is
    some 83
    above the federal and Illinois air quality standard of
    0.12 ppm by yolume.
    However, the ozone problem is not specific
    to Illinois.~ The United States Environmental Protection Agency
    (USEPA) estimates that there are more than 80 urban areas where
    the ozone air quality standard is being exceeded.
    New and emerging scientific data
    is shedding more light
    on
    the effect high levels of ozone have on the general public.
    Ozone severely affects
    individuals with chronic heart,
    lung,
    and
    circulatory system diseases.
    Otherwise healthy individuals who
    exercise while ozone levels are high can experience
    reduced
    functioning of the lungs,
    leading
    to chest pains, coughing,
    wheezing, and pulmonary congestion.
    In addition to the health
    effects, ozone has been estimated to cause
    two to three billion
    dollars worth of crop damage nationally each year.
    Also,
    because
    the Chicago area has exceeded the ozone standard repeatedly,
    USEPA has
    imposed a construction ban on the Chicago non—
    attainment area which prohibits the construction or modification
    of major air pollution sources and thus restricts the economic
    development of the Chicagoland area.
    In its comments
    (P.C.
    23),
    the Illinois Environmental
    Protection Agency
    (Agency)
    noted
    that in the early
    1970’s,
    the
    average summertime RVP of gasoline was approximately 9.0 psi.
    However, with the phasing out
    of leaded gasoline, refiners began
    adding butane to meet octane requirements which increased the RVP
    levels.
    The Agency noted
    that it was not aware
    that the typical
    summer RVP of gasoline
    in Illinois was well above 9.0 psi until
    late
    in
    1987.
    As
    a result, Agency estimates of VOC emissions
    during
    the 1970’s and 1980’s from both stationary and mobile
    gasoline-related sources have been made using
    an RVP
    approximately 20—25
    lower
    than
    actual
    RVP.
    Accordingly,
    those
    emissions have been underestimated by approximately
    20—25.
    Thus, during this period
    that the Agency had been actively
    engaged
    in imposing reasonably available control technologies
    (RACT) on major sources of air pollution,
    the increase
    in
    gasoline RVP was causing
    a significant increase
    in the emission
    of ozone precursors.
    Much of
    the benefit of the RACT regulations
    was lost as a result.
    Reducing the summertime volatility of
    gasoline
    to 1970
    levels
    is expected
    to correct this situation.
    i-See.,
    e.g.,
    Ecko Glaco Corp.
    v.
    EPA,
    PCB 87—41
    (December
    17,
    1987), wherein the Board found
    “frequent, pervasive and
    substantial violations of ambient air quality standards for ozo~~
    in Northern Illinois”.
    (pp.4—5)
    103—154

    —3—
    To cure all of these ozone related problems, federal, state,
    and local governments have attempted to limit the emission of
    ozone precursors.
    One method of limiting such emissions
    is to
    reduce the volatility of gasoline.
    Volatility,
    generally
    speaking,
    is the rate at which a substance evaporates into the
    atmosphere
    ——
    the higher the volatility,
    the faster the
    evaporation.
    As will be discussed below,
    reducing the volatility
    of gasoline sold
    in Illinois, and ultimately the country,
    is
    believed to be a giant step forward in solving the ozone problem.
    On August
    19,
    1987 the United States Environmental
    Protection Agency
    (USEPA) published a notice of proposed
    rulemaking
    (52 Fed. Reg.
    31274) proposing
    to require gasoline
    refineries
    to reduce the volatility of
    their summertime
    commercial fuels and to require manufacturers of most gasoline
    fueled vehicles to make minor improvements
    in the design of
    their
    existing evaporative emission control systems.
    The purpose of
    USEPA’s action was to control the emission of organic materials
    which are precursors
    to the formation of ozone.
    USEPA held a
    public hearing on October
    27,
    1987,
    on both the proposed
    volatility and refueling control programs and accepted public
    comment until February
    11, 1988.
    It has been estimated that reducing gasoline RVP to 9.0 psi
    in Illinois could result
    in summertime weekday emissions
    reductions of 103,000 kg/day or 41,000 tons/year.
    Such a
    reduction may reduce ozone levels by 10—15.
    Although this alone
    may not solve the ozone problem,
    it would be significant step
    forward.
    However,
    by December of 1988,
    well over one year from the
    date of USEPA’s proposed rulemaking,
    the date for the final
    adoption of a
    national gasoline volatility limit remained
    uncertain.
    This uncertainty, coupled with
    a desire to avoid
    further ozone excursions, prompted the Board
    on
    January
    5,
    1989
    to adopt an order
    requesting written public comment on various
    aspects of
    the gasoline volatility
    issue,
    i.e.,
    the feasibility
    of reducing the RVP of gasoline
    to 9.0 pounds per square inch
    (psi)
    by the summer of
    1989,
    the anticipated costs of reducing
    the gasoline volatility,
    the status of the USEPA’s rulemaking
    to
    reduce gasoline volatility,
    etc.
    Written public comments were
    received through March
    1,
    1989.
    Twenty—one
    (21) written public
    comments were submitted
    into this docket by March
    1,
    1989, by
    various members of the public and of
    the regulated community.
    An
    additional five
    (5)
    public comments were received by March
    8,
    1989.
    On March
    9,
    1989,
    the Board adopted an order stating its
    intent
    to proceed with
    a proposal
    for rulemaking.
    The Board
    noted
    that the written public comment would require careful
    review and that the pending USEPA action was uncertain;
    thus,
    further action would be forthcoming.
    103—155

    —4—
    On March
    22, 1989,
    USEPA published at
    54
    Fed. Reg.
    11868
    “Phase
    I of a two—phase reduction
    in summertime commercial
    gasoline volatility”. The federal regulation limits the
    volatility of gasoline in Illinois to 10.5 psi north of 40°
    Latitude and 9.5 psi south of 40°Latitude.
    The 40°Latitude
    line
    is an east—west line south of Beardstown,
    Champaign and
    Danville and north of Quincy, Springfield and Georgetown.
    PROPOSAL
    On April
    4,
    1989,
    the Chicago Lung Association
    (CLA)
    submitted a proposed rule,
    a statement of
    reasons, and a motion
    to waive
    the
    200 signature requirement
    of Section 28 of
    the
    Environmental Protection Act
    (Act) and Section 102.121(a)
    of
    the
    Board’s procedural
    rules,
    35
    Ill. Adm. Code 102.121(a).
    Noting that
    it was pleased USEPA acted on the gasoline
    volatility
    issue
    for
    the summer
    of 1989,
    the Chicago Lung
    Association
    (CLA)
    stated that
    it believes that the rule “does not
    provide adequate control of gasoline
    (VOC)
    emissions for
    Northeast Illinois.”
    See Statement of Reasons, p.1.
    “In light
    of the immediate need for more stringent controls on gasoline
    volatility to improve the air quality
    in Northeast Illinois,”
    CLA proposed the following rule:
    1.
    Prohibited
    Activity.
    During
    regulatory
    control
    periods
    no
    refiner,

    or wholesale purchaser—consumer shall
    sell,
    offer
    for
    sale,
    dispense,
    supply,
    offer
    for

    or
    transport gasoline whose Reid vapor pressure
    exceeds the applicable standard listed
    in paragraph
    3.

    Ethanol blend gasolines are
    defined
    as
    those
    which contain
    at
    least
    9
    ethanol
    (by
    volume).
    The maximum ethanol
    content
    shall not
    exceed
    any applicable requirements of the Clean Air Act.
    On April
    6,
    1989,
    the Board adopted an order granting the
    motion to waive the 200 signatures,
    but requiring additional
    information from the proponent before the proposal could be
    accepted for hearing.
    On April
    13,
    1989, CLA submitted its
    response to the Board’s more information order.
    On April
    27, 1989,
    the Board accepted the CLA proposal and
    directed the Hearing Officer
    to schedule hearings.
    The Board
    also noted that Section
    27(a)
    of
    the Act permits any person to
    request the Board to determine that an economic impact study
    (EcIS)
    should or should not
    be prepared.
    Nine public comments
    were received
    in response
    to this order
    (P.C.
    30—38).
    On June
    22,
    1989, the Board adopted an order noting
    the nine
    comments and determining that an EcIS need not be prepared at
    that time.
    The Board noted that the
    record compiled contained a
    fair amount of economic discussion.
    Moreover,
    the Board noted
    that hearings were scheduled
    for July 17 and 21,
    1989,
    and
    additional economic information was
    likely to be introduced
    therein.
    As
    the Board was required to make an EcIS
    determination,
    the Board determined that,
    at that time, an EcIS
    was not necessary.
    As will be discussed below, the Board
    reaffirms that determination with respect
    to the Docket A
    proposal and will not require an EcIS
    to be done.
    However, with
    respect to the Docket B proposal,
    the Board determines that an
    EcIS should be conducted.
    PUBLIC HEARINGS
    On July 17 and 21,
    1989,
    the Board conducted public hearings
    to address the CLA proposal
    to limit the volatility of
    gasoline.
    Presenting testimony on July 17,
    1989 were the Chicago
    Lung Association, United States Environmental Protection Agency,
    the Illinois Petroleum Council, Amoco Oil Company,
    Phillips 66,
    Marathon Oil Company, and the Motor Vehicle Manufacturers
    Association
    (MVMA)
    Presenting testimony on July
    21,
    1989, were
    Mobil Oil Corporation and the Chicago Lung Association.
    At hearing,
    the Hearing Officer established a post—hearing
    comment schedule, ordering that comments
    be submitted on or
    before August
    7,
    1989.
    Six post-hearing comments were submitted
    in a timely fashion
    (P.C.
    42—47).
    Mobil Oil Corporation filed
    its comments on August
    15,
    1989.
    On August
    17,
    1989, CLA filed
    an additional comment along with a motion to file instanter.
    1~03—157

    —6—
    CLA’s motion is hereby granted.
    Although Mobil’s comment was not
    submitted under
    a motion to file,
    the Board will accept the
    comment into the record.
    Mobil’s comment was submitted in time
    to permit adequate consideration; no participant will be
    prejudiced;
    and the record will be complete, which is the Board’s
    ultimate goal.
    FEDERAL VOLATILITY RULE
    A major preliminary issue raised since the Board originally
    opened this docket
    in December of 1988
    is whether Illinois need
    persevere
    in the rulemaking process
    for
    a statewide rule when the
    federal government
    is already in the process of adopting a
    nationwide regulation that will accomplish the same result.
    As
    noted above, USEPA originally proposed
    a gasoline volatility rule
    on August
    19,
    1987.
    When the Board opened this docket
    in
    December
    of
    1988, USEPA had shown no movement toward the final
    adoption of a regulation.
    It
    was not until March of 1989 that
    USEPA proceeded to final adoption of a
    rule,
    and at
    that
    it was
    only an interim measure,
    as USEPA adopted only “Phase
    I of
    a two
    phase reduction in summertime commercial gasoline volatility”.
    54 Fed.
    Reg.
    11868.
    Many comments note that USEPA’s action
    indicates that
    the Phase
    II completion of the gasoline volatility
    regulation is inevitable; therefore,
    the comments suggest that
    the Board recede
    in
    its attempt to adopt
    a rule applicable only
    to Illinois.
    In its proposal,
    CLA noted that USEPA had adopted the first
    phase of a two phase program and pointed out that USEPA had made
    no commitment as to when,
    if ever,
    the second phase would be
    promulgated.
    It was this uncertainty together with the interim
    standards of 10.5 psi
    for northern Illinois and 9.5 psi for
    southern Illinois that prompted CLA to propose the more stringent
    limitation of
    9.0 psi for all
    of Illinois for the summer of 1990
    and each year
    thereafter.
    CLA calculates
    that.
    a gasoline
    volatility
    reduction from 10.5
    to 9.0 psi
    in northeast Illinois
    would result
    in a 199.5 ton/day reduction in VOC emissions.
    (R.
    43.)
    CLA also notes
    that an Illinois Environmental Protection
    Agency
    (Agency) planning document from April
    1988,
    though not an
    official declaration of the VOC reduction value of
    various
    control options,
    indicates
    a gasoline volatility reduction from
    the then current
    levels
    (11.5 psi)
    to 9.0 psi was thought
    to be
    the largest single reduction option available in Illinois.
    Id.
    The Board
    notes that the record contains testimony of
    USEPA.
    At hearing on July
    17,
    1989 USEPA stated “today
    ...
    you
    are considering a rule submitted by the Chicago Lung Association
    which would
    limit
    the volatility of gasoline
    in the State of
    Illinois, and USEPA supports the adoption of
    this measure.”
    (R.ll.
    Emphasis added.)
    USEPA stated further
    that its proposed
    Phase
    II program
    is expected to be published by early next year,
    but implementation nationwide
    is not expected before
    1992.
    USEPA
    103—153

    —7—
    also addressed the potential benefits of early implementation,
    stating:
    According
    to
    our
    draft
    inventory,
    mobile
    source
    VOC
    emissions
    account
    for
    roughly
    50
    percent
    of
    the
    total
    VOC
    emissions
    in
    the
    Chicago,
    Illinois
    area,
    or approximately 1086
    tons
    per
    day
    (tpd).
    Reducing
    the allowable
    gasoline volatility
    to
    9.0
    psi
    in
    1990 would
    achieve
    a
    24
    percent reduction
    in evaporative
    emissions between 1990 and 1992,
    or a total of
    261
    tpd.
    The
    costs
    of
    complying
    with
    this
    program
    are
    offset
    by
    savings
    for
    consumers
    resulting
    from an
    increased
    fuel economy
    due
    to
    the
    increased
    energy density
    of
    lower
    RVP
    fuel
    and
    as
    less
    fuel
    is
    lost
    through
    evaporation
    and
    running
    losses.
    Further,
    it
    is believed that much if not all of the butane
    displaced from direct use
    in gasoline
    in order
    to comply
    with
    the volatility
    limits
    will
    be
    used
    in
    the
    production
    of
    other
    gasoline
    components.

    14—15.
    In short, USEPA supports the proposed regulation.
    It
    believes
    that Illinois can achieve
    significant emission reductions by
    requiring a summertime RVP of 90 psi beginning
    in
    1990,
    and
    it
    believes that the severity of the Chicago ozone problem requires
    Illinois to take all reasonable actions
    to protect the health and
    welfare of its citizens.
    (R. 15.)
    Based on the potential reduction in VOC emissions resulting
    from early implementation of
    this proposal and based on USEPA’s
    express support
    for the proposal,
    the Board is not inclined
    to
    await
    for implementation of USEPA’s Phase
    II program.
    This Board
    has a statutory duty
    to determine,
    define and implement the
    environmental control standards applicable
    in Illinois,
    pursuant
    to Section
    5 of the Environmental Protection Act
    (Act).
    The
    Board believes that the severity of the ozone problem requires
    prompt, affirmative action on the part of regulators,
    state and
    federal alike.
    ECONOMIC IMPACT
    The Board’s Order of June
    22,
    1989
    in this docket addresses
    the
    issue of whether an economic impact study
    (EcIS) would be
    prepared.
    As noted in that Order,
    Section 27(a) of the Act
    requires
    that
    the Board make
    a determination within 60 days of
    the acceptance of
    a proposal.
    Noting
    that the record at
    that
    time already contained
    a fair amount
    of
    economic information and
    noting further
    that hearings were scheduled at which additional
    economic information was expected to be submitted,
    the Board
    103—159

    —8—
    determined that an EcIS need not be prepared.
    The Board
    noted,
    however,
    that Section 27(a) permits the Board to determine after
    the
    60 days that an EcIS need be done if new information
    indicates that one need be done.
    The Board here addresses the
    issue of economic impact and the need for an EcIS.
    Section 27(a) of the Act sets forth the Criteria that the
    Board
    is
    to consider when determining whether an EcIS should be
    conducted.
    Section
    27(a) states
    in relevant part:
    The Board shall
    reach its decision based on its
    assessment of the potential economic impact of the rule,
    the potential
    for consideration of
    the economic impact
    absent such
    a study,
    the extent,
    if any,
    to which the
    Board is free under
    the statute authorizing the rule to
    modify the substance of the rule based upon the
    conclusions of
    such
    a study,
    and any other
    considerations the Board deems appropriate.
    Many of
    the commenters, primarily the refineries and
    gasoline distributors, specifically requested that the Board
    determine that an EcIS
    be prepared.
    In comments and at hearing,
    the Illinois Petroleum Council
    (IPC) strongly advocated for the
    preparation of an EcIS, arguing that
    in declining to require an
    EcIS,
    the Board
    is overlooking several key considerations.
    First,
    IPC argues
    that Illinois
    is
    the hub of
    the midwest
    gasoline supply and distribution system, and asks what impact
    would limiting gasoline volatility
    to 9.0 psi
    in Illinois have on
    both Illinois and other
    states supplied by Illinois based
    refineries.
    Second,
    IPC asks how much improvement
    in Illinois’
    ambient air quality would volatility control produce,
    especially
    in light of the large summertime natural source volatile organic
    compound emissions
    in the state.
    Third, what
    is the real cost to
    Illinois consumers
    and
    is this cost reasonable and commensurate
    with the expected improvement
    in air quality?
    Fourth, would
    not
    a 1.0 psi waiver
    for
    ethanol blends negate the improvement
    in
    Illinois’
    air quality expected from a reduction
    in RVP levels?
    And finally,
    IPC asks does the Clean Air Act allow the state
    to
    adopt more restrictive environmental controls absent
    their
    inclusion
    in an approved state implementation plan
    (SIP)?
    Other
    cornrnenters, primarily the proponent CLA and NESCAUM,
    argue that the economic information
    in the record
    is sufficient
    to support the proposed regulation,
    that an EcIS need not be
    prepared, and that the impact will
    be reasonable.
    In support of
    their argument, these commenters note that the Chicago area
    is
    non—attainment for ozone.
    As
    a result, Chicago
    is currently
    under
    a construction ban,
    which means
    that no new construction
    or
    modification of
    a major air
    emission source may take place.
    This
    alone restricts economic development
    of the Chicago area.
    CLA
    estimates that adoption of this
    rule will result
    in emission
    reductions
    of approximately 199.5 tons/day.
    CLA further
    1’)3—160

    —9—
    estimates that this value
    is nine percent of
    the estimated 1988
    VOC inventory of
    2,186.9 tons/day and thirteen percent of the
    reductions estimated by USEPA to be necessary to bring the
    Chicago area into attainment,
    and thereby lift the construction
    ban.
    USEPA estimates that early implementation of this rule will
    reduce emissions by 261 tons/day.
    CLA also notes that the Agency
    has noted its belief that the emission reductions
    resulting from
    a gasoline volatility limit of 9.0 psi would be the largest
    single reduction option available
    in Illinois.
    In further support of
    their position, these commenters argue
    that other benefits would
    result
    as well.
    They argue that
    adoption of this
    rule would go a long way toward avoiding the
    adverse health effects,
    noted above,
    associated with excessive
    ozone levels.
    In addition, crop damage resulting from high ozone
    levels would be minimized.
    CLA argues that Illinois crop yields
    will
    improve, as major
    crops
    for
    the Illinois farm economy are
    sensitive to ozone-induced yield
    loss even at the relatively low
    concentrations at which ozone
    is found
    in the farm areas of the
    state.
    For Illinois this was valued to be worth
    226 million
    dollars for
    a ten percent reduction
    in ozone levels experienced
    in
    1980.
    As the estimated ozone reduction resulting from
    implementation of this rule is two percent,
    this calculates to a
    potential benefit
    of approximately
    45
    million dollars.
    Also,
    CLA
    and USEPA point out that another benefit will be increased fuel
    economy due
    to the increased energy density
    of lower RVP fuel and
    as less fuel is lost through evaporation and running
    loss.
    As
    a preliminary matter,
    the Board notes
    that the nature of
    this rulemaking
    is somewhat different
    from most other
    rulemakings.
    In this rulemaking,
    the Board
    is being asked to
    adopt early
    a
    rule which USEPA
    is in the process of
    promulgating.
    In
    its consideration of this
    rule, USEPA has
    considered and addressed the economic impact upon the regulated
    community.
    USEPA
    has already
    adopted the first phase of
    that
    rule.
    USEPA has stated on the record
    in this proceeding
    that
    it
    expects
    to publish the final phase
    of
    its rule early next year,
    with an effective date of 1992.
    The final
    rule is expected
    to
    limit the volatility of gasoline
    in Illinois,
    and other areas,
    to
    9.0 psi RVP.
    fhus,
    a 9.0 psi RVP limitation appears inevitable,
    which means
    that the economic impact will result, whether the
    Board acts
    or
    not.
    The question,
    then,
    in determining whether
    an EcIS need be
    conducted
    is
    not necessarily what is
    the economic impact of
    a
    gasoline volatility rule
    in Illinois;
    more precisely the question
    is what
    is the economic impact of early implementation of the
    federal gasoline volatility
    rule
    in Illinois?
    The
    record indicates that reducing the volatility
    of
    gasoline
    from 11.5 to 9.0 psi, taking all of
    the above
    considerations into account, would
    result
    in
    a price increase of
    103—161

    —10—
    gasoline of approximately 1—3 cents per gallon.
    This estimate
    preceded adoption by USEPA of phase
    I of its rule.
    The record
    is
    not clear on what the approximate cost per gallon would be in
    Illinois now that the standard is 10.5 psi.
    In other words,
    the
    record does not articulate what the cost of reducing the
    volatility of gasoline from 10.5 to 9.0 psi will be per gallon.
    The Board can only assume that
    it will be less than or equal
    to
    1—3 cents per gallon.
    Market forces as they are,
    the economic
    burden of this rule will still be carried by the consumer.
    In
    relation to the benefits derived from this rule,
    however, a 1-3
    cent cost per gallon of gasoline is not unreasonable.
    And again,
    part of this cost increase will be offset by increased fuel
    economy resulting from the use of
    lower RVP gasoline.
    Put another way,
    the total cost of
    implementation appears
    to
    be less than $1000 per
    ton of VOC controlled.
    According to P.C.
    42,
    the Office of Technology Assessment has estimated the cost
    to
    be
    in the range of $320
    700 per
    ton of VOC controlled.
    CLA
    notes that the Agency has estimated the cost effectiveness
    (using
    the old emission inventory)
    for gas volatility reduction to 9.0
    psi was $982
    1,129 per ton of VOC controlled.
    CLA’s own
    estimates put the costs of control
    at approximately $1,000 per
    ton.
    CLA notes
    that this cost estimate
    is well within the range
    of cost effectiveness values associated with the adoption of
    other Reasonably Available Control Technology
    (RACT)
    regulations.
    Mobile, however, estimates that the cost would be
    approximately $2,000/ton.
    The Board notes
    that these cost estimates include a
    consideration of most of
    the issues raised by the potentially
    regulated community.
    The Board
    turns next to one of
    the major
    issues that has proven more difficult to analyze.
    Many
    cominenters have argued that
    a 9.0 psi RVP limitation
    in Illinois
    would set Illinois apart from the rest of
    the midwest region,
    making Illinois,
    for all effective purposes, a “specialty” state
    in terms of refining and distributing gasoline.
    Generally,
    the
    midwest region
    includes Illinois,
    Indiana, Wisconsin, Michigan,
    Iowa,
    Missouri, Minnesota,
    and Kentucky.
    Of these,
    Indiana,
    Wisconsin, Michigan,
    Iowa Minnesota and Kentucky are subject
    to a
    10.5 psi RVP standard.
    The southern portion of Illinois,
    Missouri, Oklahoma, Tennessee,
    and Arkansas are subject ot a 9.5
    psi standard.
    The commenters argue
    that limiting the volatility
    of gasoline in Illinois
    to 9.0 psi while many of the other states
    operate under
    a 10.5 psi standard would
    impose a burden upon the
    refiners and distributors
    in three fundamental
    respects.
    First, the commenters argue that the distribution network
    is
    not equipped to accommodate
    a
    9.0 psi RVP gasoline.
    Illinois
    refineries are presently producing gasolines of 10.5
    to 9.5 psi
    for distribution
    in Illinois,
    Indiana, Wisconsin,
    etc.
    10.5 psi
    gasoline is presently being distributed
    in Indiana, Wisconsin,
    and the northern part of
    Illinois,
    i.e.,
    north of
    40 degrees
    1~3—l62

    —11—
    Latitude.
    9.5 psi gasoline
    is presently being distributed in
    southern Illinois and Missouri.
    Most of
    the gasoline supplied in
    the midwest
    is provided primarily by refiners in and around
    Illinois.
    In addition, the commenters argue that supplements
    to
    this supply are provided by shipments from the Gulf Coast and
    from Canada.
    While
    the cornmenters note that Gulf Coast supplies
    have become tight due primarily
    to pipeline capacity constraints
    and that imports from Canada have been rather sporadic, they
    argue that it would be difficult
    to supplement the midwest
    region’s supply of gasoline from these sources because
    it would
    be difficult for the pipeline operators to supply only Illinois
    with 9.0 psi gasoline while
    the remainder of the upper midwest
    region receives 10.5 psi gasoline.
    Second,
    the commenters
    argue that
    if they are required to
    produce and market
    a 9.0 psi gasoline, or
    a “specialty” gasoline
    product,
    they will be placed
    in
    a position of economic
    disadvantage with their out-of-state competitors who are not
    required
    to produce 9.0 psi gasoline.
    These commenters argue
    that because their competitors will not be required
    to incur
    the
    expense of producing 9.0 psi product,
    these competitors will be
    able
    to sell their~product
    at
    a lower price.
    Third,
    the commenters argue
    that limiting Illinois to a
    9.0
    psi standard would impose a
    burden on gasoline suppliers
    in times
    of spot shortage.
    For example,
    one of the hearing participants
    (Mobil) offered the following testimony on this point:
    Right
    now
    if we have a spot shortage
    in Chicago or
    Illinois,
    or somewhere
    in the State of Illinois,
    some
    city has a spot shortage,
    we can bring product
    in from
    Minnesota,
    we can bring
    it from Indiana,
    we can bring
    it
    in from Wisconsin.
    We cover
    it like that.
    And it
    is no
    problem.
    But
    if you have
    a nine pound standard
    in Chicago,
    and there
    is
    a
    ten and a half pound standard
    in Indiana,
    we can’t do that.
    Now, where do we go for the product
    to cover
    that temporary disruption?
    We don’t know.
    (R.
    272.)
    Thus,
    the record indicates that
    in times of spot shortages,
    Illinois,
    if
    under
    a 9.0 psi standard,
    would be unable
    to
    conveniently make up the shortage using supplies from other
    states.
    It
    is based upon these issues and concerns that
    the Board
    has determined that the appropriate course
    is
    to split
    this
    docket
    into two separate proposals,
    Docket
    (A) and Docket
    (B).
    103—163

    —12—
    In Docket
    (A),
    the Board proposes a 9.5 psi RVP limitation
    statewide, and determines that an EcIS need not be conducted.
    Because the southern portion of Illinois,
    i.e., south of
    40
    degrees Latitude,
    is currently operating under a 9.5 psi
    standard, the Board believes that much of the concern noted above
    will be avoided.
    In other words,
    Illinois refiners are currently
    producing 9.5 psi gasoline for distribution in Illinois, and
    Missouri.
    Illinois will not be a “specialty” state;
    Illinois
    refiners will not be placed
    in a position of economic
    disadvantage.
    Since refiners are producing 9.5 gasoline for
    southern Illinois,
    there should be little difficulty in producing
    it for northern Illinois as well.
    Further,
    in times of spot
    shortage
    in northern Illinois, the marketers can turn to supplies
    in southern Illinois and adjoining states
    to make up the
    difference.
    According to USEPA’s post hearing comments, adoption
    of
    a 9.5 psi
    limit could result
    in almost 80
    of the potential
    benefits
    to be derived from a
    9.0 psi standard
    (P.C.
    44).
    In Docket
    (B), however, the Board proposes the 9.0 psi RVP
    limitation statewide and determines that an EcIS need only be
    conducted on the issues discussed above, namely whether
    a 9.0
    standard
    in Illinois would be economically or technically
    unreasonable or pose
    an economic hardship in terms of supplying
    gasoline
    to Illinois and the other midwestern states; whether
    a
    9.0 standard in Illinois would impose economic hardship in events
    of spot shortages and an economic analysis of granting the 1.0
    psi exemption for ethanol blenders.
    As will bediscussed below,
    the Board also requests that the EcIS
    review the impact
    if the
    proposed subsection
    (i)
    requirement that retail outlets and other
    facilities meintain records regarding each delivery of
    gasoline.
    The Board specifically requests
    that
    the Department of
    Energy and Natural Resources
    (DENR) prepare and submit this EcIS
    to the Board
    on or before June
    30,
    1989.
    The Board makes
    this
    request
    so that
    it will have time
    to adopt
    the rule
    if found
    to
    be
    feasible in time
    for
    1991 implementation.
    TECHNICAL FEASIBILITY
    As previously described,
    “volatility” of
    a liquid
    is
    a
    measure of its tendency to evaporate.
    Gasoline
    is
    a mixture of
    a
    number
    of hydrocarbon components which are very volatile under
    most conditions.
    Certain hydrocarbons, known as “light—end”
    hydrocarbons,
    are among the most volatile components of
    gasoline.
    Butane
    is
    a light-end hydrocarbon.
    Light—end
    hydrocarbons make up the largest part
    of gasoline vapor.
    Evaporated gasoline, however, will also include certain amounts
    of heavier
    hydrocarbons.
    Benzene, one of the heavier compounds,
    is a known carcinogen
    in addition
    to contributing
    to ozone.
    Reformulation
    As a practical matter,
    implementation of this rule will be
    103—164

    —13—
    effectuated by the reformulation, or alteration of the chemical
    composition,
    of the gasoline distributed in Illinois.
    The
    primary approach that gasoline refiners would take to reduce the
    volatility of gasoline products would be to add less butane
    during the refining process.
    Apparently,
    in the early 1970’s,
    gasoline volatility had an average RVP of approximately 9.0
    psi.
    With the phasing out of lead
    in gasoline, refiners began to
    add butane to gasoline
    to meet octane requirements.
    Butane was
    chosen because
    it
    is relatively inexpensive and because
    it
    increases octane.
    However,
    it also substantially increases
    volatility.
    P.C.
    42,
    p.1..
    Thus,
    reducing the amount of butane
    will have the result of decreasing the volatility of the
    gasoline.
    Based on a review of the record,
    the Board determines that
    reducing the level of butane
    in gasoline products would be
    technically feasible.
    In
    most cases,
    refiners simply need not
    add butane to the gasoline product.
    Evidence
    for
    this
    determination is found
    in the fact
    that refiners
    in Illinois
    already produce gasoline with a volatility of 9.5 psi RVP.
    However, many participants, primarily the refiners, note
    that by not adding the butane
    to gasoline,
    the refiners will
    incur costs
    for butane removal,
    butane storage, loss of butane
    value, octane value replacement, and/or compliance testing.
    One
    commenter,
    P.C.
    6,
    further notes that butane
    is contained in
    crude
    oil
    as well as being produced
    in processing units.
    Processing units like the catalytic reformer and fluid catalytic
    cracker increase butane production when operating
    to produce
    higher
    octane gasolines.
    These comrnenters argue
    that the surplus
    butane would have no economic value
    in the refinery.
    Thus,
    new
    markets for the butane must be developed.
    Once these markets are
    developed,
    the refiner must make refining modifications as well
    as construct storage and transportation facilities.
    These
    comrnenters believe
    that the costs associated
    with such facilities
    would be excessive.
    The Board is not persuaded
    by the record that
    it would be
    technically infeasible
    for
    refiners
    to remove,
    store, and/or
    reuse the butane at
    a later
    date.
    The Board can see
    no reason
    why the refiners cannot
    remove the butane during
    the regulatory
    control period,
    i.e.,
    July and August,
    and then reuse
    it during
    the colder winter months when ozone formation
    is not
    a problem.
    The commenter’s argument that storage facilities must be
    constructed
    is
    not,
    in and of
    itself, despositive
    of this
    issue.
    The Board
    is aware of the existence 9f potential storage
    facilities
    that are apparently being unused.
    The Board
    2For example,
    the Board notes
    the existence of potential
    storage facilities
    for butane at the former Texaco Refinery
    in
    Lemont,
    Illinois.
    103—165

    —14—
    specifically requests comment on the potential availability of
    these and other facilities for the purpose of butane storage.
    Further,
    the Board notes that the commenters’
    arguments are
    directed more to the merits of the gasoline volatility rule in
    general than to the early implementation of the
    rule.
    When the
    federal rule is adopted,
    the refiners will be required to remove
    the butane and do something with
    it.
    The Board’s consideration
    of early implementation of the rule merely requires the refiners
    to begin the search
    for storage facilities or new markets sooner
    than the federal rule would.
    Safety/Driveability
    Many of the commenters argue that the Board should not
    proceed with this rulemaking because 9.0 psi RVP gasoline would
    likely give noticeably degraded driveability performance in the
    early spring and late fall when product would be
    in the
    distribution system to ensure compliance with the restriction
    period.
    One of the commenters,
    P.C.
    48, submitted
    a study
    prepared August
    1,
    1988 for
    submission
    to the American Petroleum
    Institute.
    Results of the study are as follows:
    (a)
    30
    of the vehicles tested showed significant
    deterioration
    in driveability performance
    (at least two
    or more have hesitation and/or
    stalls) with 9.0 psi RVP
    fuel compared
    to the typical 13.5 psi RVP fuel.
    (b)
    There were nearly twice
    as many start stalls with the
    9.0 psi RVP fuel compared to the 13.5 psi RVP fuel
    within the 51 vehicle fleet
    tested.
    (C)
    Average driveability performance with the tank fuel
    (average RVP
    13.0 psi) was similar
    to performance with
    the nominal
    13.5 psi RVP test
    fuel.
    (d)
    Test temperatures
    for this program
    ranged from 21—30
    degrees
    F;
    however,
    it
    is expected that lower
    temperatures than those observed during this test could
    occur
    in some ASTM Class
    C areas during March and
    November.
    Many other participants submitted similar comments.
    The CLA argues that vehicle performance will not deteriorate
    as
    a result of the reduced volatility,
    but rather vehicle
    performance and safety may improve.
    CLA points
    to the state of
    California
    as an example where
    fuel volatility has been reduced
    since 1971 without commensurate driveability problems.
    CLA
    further points to the comments of NESCAUM and the Motor Vehicle
    Manufacturers Association
    (MVMA)
    for support of
    its position.
    At hearing,
    the Board received testimony from a
    103—166

    —15—
    representative of MVMA who stated:
    Because every vehicle on the road today was designed and
    built
    to operate on nine pound volatility gasoline, MVMA
    does not believe that vehicle performance would suffer
    from volatility control.
    In fact we believe that
    performance would be increased in the hot summer months
    due to reduction in vapor
    lock and stalling on those hot
    days when ozone is a problem.
    However, the concern
    remains regarding vehicle performance in very cold
    weather.
    This should be addressed by adjusting
    tl’.-
    effective date
    of the control period.
    It
    is not a
    reason to abandon volatility controls.
    (R.2l4—2l5)
    Based on the record,
    the Board is not persuaded that
    implementation of this rule will result in safety
    or driveability
    problems.
    The study submitted
    in P.C.
    48 was conducted under
    temperatures of
    21
    30 degrees
    F.
    The Docket
    (A) proposal
    requires 9.5 psi gasoline at the retail outlet during July and
    August.
    The Board does not believe
    it likely that northern
    Illinois will
    be subject
    to temperatures as cold as that during
    those months.
    The Docket
    (B) proposal
    would require 9.0 psi
    gasoline at the retail outlet
    from June
    1 to September
    15.
    The
    Board does not believe
    it likely that northern Illinois will be
    subject
    to
    temperatures below
    30 degrees during this period
    also.
    As
    a
    result,
    the Board
    is not persuaded that gasoline with
    a volatility of 9.5 psi,
    or 9.0 psi for that matter, will pose
    a
    safety/driveability problem in Illinois during the regulatory
    control period here proposed.
    In colder climates,
    lower
    volatility gasoline may pose problems,
    but the Board believes
    that
    those problems should not
    be present during the
    implementation of either
    of these proposals.
    ENFORCEABILITY
    At hearing,
    the IPC raised
    a valid question regarding
    whether
    the Clean Air Act allows the state to adopt more
    restrictive environmental controls absent
    their
    inclusion in an
    approved state implementation plan(SIP).
    After noting
    the recent
    case of American Petroleum Institute
    v.
    New York State Department
    of Environmental Conservation,
    29 ERC 1457 (D.N.Y.
    April
    4,
    1989),
    IPC asks:
    Since Illinois currently dces not have an approved SIP
    and
    is bound from developing one until after
    the FIP has
    been promulgated or
    settled, which should be sometime in
    1990, how can the Pollution Control
    Board possibly act
    on the Chicago Lung Association’s proposal?
    (IL
    81.)
    The Board does not believe
    it
    is precluded from promulgating
    this regulation based on the decision
    in the API case.
    In fact,
    the Board believes
    it
    has every
    right and power granted under the
    103—167

    —16—
    Environmental Protection Act (Act),
    Ill.
    Rev. Stat.
    1987,
    ch.
    111—1/2, pars.
    1001 et seq., to proceed with this proposal.
    The
    Board is aware, however, that under
    the API decision a final
    adopted rule will not be enforceable
    untiTit
    is approved as
    a
    revision to the SIP.
    As USEPA has appeared
    in this rulemaking
    proceeding and has articulated its support for the rule, the
    Board believes that USEPA will work expeditiously
    to approve the
    rule as a revision
    to the SIP.
    Thus,
    the Board does not agree
    with IPC that the State must have an “approved SIP” before it can
    proceed with this rule;
    rather,
    the State must submit the adopted
    rule to USEPA as a revision
    to the SIP, and once approved as
    such, the rule can be enforced.
    ETHANOL
    EXEMPTION
    Many comrnenters specifically stated that
    if the Board
    proceeds with the proposal
    to limit the volatility of gasoline,
    then the Board should not
    include the 1.0 psi exemption for
    ethanol blended gasoline,
    as CLA proposed.
    These commenters
    argue that including
    a 1.0 psi exemption for blended gasolines
    directly contradicts the intent of limiting the volatility of
    gasoline,
    i.e.,
    to reduce the formation of ozone.
    CLA states
    in its submissions
    to the Board
    that
    it has
    included the 1.0 psi exemption for the following reasons.
    First,
    the USEPA rule allows a one pound exemption for gasohol (ethanol
    blends).
    To be as parallel as possible with the federal rule and
    to avoid confusing the regulated community, CLA retained the
    gasohol exemption.
    Second, gasohol
    is typically made by “splash
    blending”
    in which
    a certain amount of ethanol
    is put into a tank
    and
    to it
    is added
    a certain amount
    of finished gasoline,
    or vice
    versa.
    For example,
    in an area where 10.5 psi gasoline
    is sold,
    the ethanol blends will use that as
    a base and end up with a
    gasohol with a volatility about one psi higher than the base
    gasoline,
    or 12.5 psi.
    CLA argues that
    if gasohol is required to
    meet the same volatility limit as gasoline,
    i.e.,
    9.0 psi,
    gasohol blenders would require a special blending grade gasoline
    of 8.0 psi, which is not available.
    Finally, CLA states that
    both gasoline and gasohol will have their volatility reduced by
    1.5 psi under, the proposed rule.
    Thus,
    a significant reduction
    in the emissions from both fuels will result.
    Additional
    emission reductions could be made by further reducing the
    volatility of both gasoline and gasohol and that option may be
    appropriate for the Board
    to consider
    in the future along with
    other VOC reduction measures.
    The Board has retained the ethanol exemption
    in both Dockets
    (A) and
    (B); however, certain revisions have been made.
    The
    Board has retained the 1.0 psi exemption to insure that
    this
    rulemaking
    is as parallel
    to the federal rule as possible.
    Again,
    the Board notes that the proper
    focus
    for this rulemaking
    is early implementation of the forthcoming federal
    rule.
    103—168

    —17—
    Consistent with this
    intent,
    the Board believes that it would not
    be feasible
    to require ethanol blends
    to meet the same standard
    when the gasoline that
    it
    is blended with is already at that
    level.
    The record indicates that when ethanol
    is blended with
    gasoline,
    the ethanol raises
    the RVP approximately 0.7 psi.
    For
    this reason the Board has added the additional language to
    proposed Section 215.585(c),
    below.
    This language states that if
    after blending the RVP
    is raised 0.7 psi,
    nothing else shall be
    added so as to use up the remaining 0.3 psi exemption.
    The
    intent of this language
    is
    to insure that only ethanol is added
    to the gasoline,
    resulting in the increased RVP.
    BOARD
    REVISIONS TO PROPOSAL
    Docket A
    The Board’s proposed regulation
    in Docket A is similar
    to
    that proposed by CLA.
    However, certain additions and revisions
    have been made beyond that already discussed in this Opinion.
    The Board has drafted the proposed text in the form required
    under the Illinois Administrative Procedure Act
    (APA)
    and
    regulations adopted thereunder.
    Certain definitions have been
    proposed
    (“Ethanol blend gasoline”,
    “Reid vapor pressure”,
    “Retail outlet”, and “Wholesale purchaser—consumer”), and those
    materials
    that appear
    to be
    incorporated into the text of the
    rule have been put into
    the
    form proper
    for incorporations by
    reference
    in Section
    215.105.
    Subsection
    (a)
    sets forth
    the
    general prohibitions
    of selling, dispensing,
    etc., gasoline which
    exceeds the
    limitations set forth
    in subsequent subsections.
    The
    Board has revised
    this language to clarify that
    it
    is only
    gasoline sold
    in Illinois that
    is regulated.
    Also the Board has shortened the regulatory control period
    in Section 215.585(a)(l) and
    (2)
    to cover July
    1
    to August
    31 of
    each summer.
    As
    a practical matter the Board has left
    it
    to the
    discretion
    of the refiners and wholesalers as
    to when they will
    begin the production and distribution of
    lower volatility
    gasoline for
    it
    to be available at retail outlets by July
    1.
    Note that this applies only
    for the Docket A proposal.
    Subsections
    (d) through
    (g)
    address the methods by which testing
    and sampling
    are
    to take place.
    The Board has attempted to
    remain as close
    to the federal rule as possible.
    Finally,
    the
    Board has added Subsection
    (h),
    a requirement
    that refiners and
    suppliers maintain records of
    the gasoline produced and shipped
    by them.
    Docket B
    In addition to the changes discussed above,
    the Board has
    proposed
    in this Section 215.585(b)
    a 9.0 psi RVP limitation.
    The regulatory control period beginning 1992 and each year
    thereafter has also been extended to June
    1
    to September 15.
    103—169

    —18—
    This is to parallel the federal rule as much as possible.
    Also,
    the Board has added subsection
    (i) which will require
    retail
    outlets and other similar facilities
    to maintain records
    regarding each delivery of gasoline so as to aid in the
    enforcement of the rule.
    The Board requests that-the EcIS review
    the impact of this proposed language as well.

    or transport for use in Illinois
    gasoline whose Reid vapor pressure exceeds the
    applicable limitations
    set forth
    in subsections
    (b) and
    (c) during the regulatory control periods set forth as
    follows:
    1)
    The regulatory control period
    for calendar rear
