    UNITED STATES of America, Plaintiff-Appellee,
    v.
    Charles A. EIDSON, Sandra A. Eidson, Defendants-Appellants.
    March 31, 1997.
    Appeal from the United States District Court for the Middle
    District of Florida. (No. 92-00094-CR-T-25(A), Lee P. Gagliardi,
    Visiting Judge.
    Before ANDERSON, Circuit Judge, and KRAVITCH and HENDERSON, Senior
    Circuit Judges.
    KRAVITCH, Senior Circuit Judge:
    The    Clean   Water    Act    ("CWA"      or   "the    Act")   prohibits   the
    addition of any pollutant into navigable waters from any point
    source.    33 U.S.C. §§ 1311(a), 1362(12).                  It defines "navigable
    waters"    to   mean    "waters    of    the    United    States,    including   the
    territorial seas."       33 U.S.C. § 1362(7).            The primary issue before
    this court is whether the drainage ditch into which appellants'
    company discharged industrial wastewater was a "navigable water"
    within the meaning of § 1362(7).
    I. Background
    Cherokee Trading Partners, Inc. ("Cherokee") was a Delaware
    corporation with its principal place of business at 5118 Ingraham
    Street in Tampa, Florida.1              Charles Eidson was the president of
    Cherokee    and   his    wife,    Sandra       Eidson,   was   its   secretary   and
    1
    From 1985 until 1989, the Eidsons were corporate officers
    of Cherokee Oil Co. Ltd. When this company was dissolved in 1989,
    Cherokee Trading Partners took over its operations. Both
    companies will be referred to in this opinion as "Cherokee."
    registered agent.   Cherokee operated a used oil recycling and
    wastewater disposal business.    The company collected used oil from
    businesses for free or for a small fee, brought the oil back to its
    facility, reduced the water content if necessary, and then resold
    the oil to other businesses.    For a slightly higher fee, Cherokee
    collected and agreed to dispose properly of industrial wastewater.
    On April 25, 1990, a Tampa police officer observed a Cherokee
    truck parked at the intersection of Ingraham and O'Brien Streets,
    approximately 100 yards from the company's facility.    The officer
    noticed a "sludge substance" being pumped from the truck into a
    storm sewer that drained into a storm drainage ditch connecting
    Ingraham and Commerce Streets.    At the time of discharge, a light
    flow in the storm drainage ditch continued northward into a nearby
    drainage canal that ran east-west along Commerce Street and that
    eventually emptied into Tampa Bay.
    While the officer was observing the scene, Sandra Eidson
    approached him. She stated that she was vice-president of Cherokee
    and that she had told the driver of the truck to pump the substance
    into the storm sewer.   She further informed the officer that the
    liquid had come from an underground fuel tank in a gasoline station
    and had been used to rinse the tank to eliminate any residual
    gasses,2 but that Cherokee had permission to pump into the sewer.
    When questioned by an environmental inspector later that day,
    Charles Eidson stated that he had given Sandra Eidson permission to
    have the driver dump the contents of the truck into the sewer.
    2
    Subsequent laboratory tests revealed that the substance
    pumped from the truck into the sewer contained a number of
    priority pollutants.
    The unauthorized discharge of pollutants on April 25, 1990 was
    hardly an isolated incident at the Cherokee site.                Upon the
    instruction   of   Charles   and   Sandra   Eidson,   Cherokee   employees
    routinely discharged industrial wastewater from trucks onto the
    ground at the Cherokee site or into the woods and bushes of an
    adjacent lot.      Cherokee employees also went to great lengths to
    conceal these discharges from environmental regulators. In company
    documents, they inventoried wastewater that had been discharged
    onto the ground in a fictional "Tank 8." In anticipation for one
    announced environmental inspection, Cherokee employees imported
    truckloads of dirt to hide the site's gross soil contamination. At
    the same time that it was discharging industrial wastewater in
    violation of its operating permits and governing environmental
    laws, Cherokee was routinely assuring its customers that it was
    treating and disposing of contaminated wastewater in accordance
    with all applicable environmental laws, regulations, and permits.
    Charles and Sandra Eidson were indicted and charged with one
    count of violating the CWA, 33 U.S.C. §§ 1311(a), 1319(c), by
    knowingly discharging or causing the discharge of pollutants into
    navigable waters of the United States. They were also charged with
    three counts of violating the mail fraud statute, 18 U.S.C. § 1341,
    by devising and implementing a scheme to defraud in which they used
    false representations to solicit business customers for Cherokee's
    wastewater disposal business.3      Following conviction by a jury on
    all counts, Charles and Sandra Eidson were sentenced to 70 and 37
    3
    The three separate counts of mail fraud stem from the
    mailing of invoices for the disposal of wastewater to three
    different companies in August and September 1990.
    months, respectively.       This appeal followed.
    Concluding that the drainage ditch connecting Ingraham and
    Commerce Streets is a "navigable water" under the CWA and rejecting
    appellants' other challenges, we AFFIRM their convictions. Finding
    an insufficient factual basis for two of the sentence enhancements
    imposed by the district court, we VACATE their sentences and REMAND
    for resentencing.
    II. Discussion
    A. Count I:    Clean Water Act
    With respect to their CWA convictions, appellants claim that
    the district court erred in denying their motions for judgment of
    acquittal     made     pursuant       to    Fed.R.Crim.P.       29(a).          Most
    significantly, they claim that the government provided insufficient
    evidence to prove that the storm drainage ditch connecting Ingraham
    and Commerce Streets was a "navigable water" within the meaning of
    § 1362(7) of the CWA.4 We consider appellants' legal claim de novo,
    reviewing    the     evidence   in    the   light    most     favorable    to    the
    government.     United States v. Mejia, 
    97 F.3d 1391
    , 1392 (11th
    Cir.1996).
    Congress    enacted    the   CWA   "to    restore    and   maintain     the
    chemical,    physical,    and    biological       integrity    of   the   Nation's
    4
    Appellants also assert that there was insufficient evidence
    to prove that they were responsible for the discharges and that
    the discharged substance was a pollutant. These claims are
    without merit. Witnesses testified that both defendants admitted
    responsibility for the discharge of the substance into the storm
    sewer. In addition, the "sludge substance" discharged from the
    Cherokee truck, which had been used to remove gasses from an
    underground storage tank at a gasoline station, tested positive
    for numerous substances classified as pollutants by the
    Environmental Protection Agency ("EPA").
    waters."     33 U.S.C. § 1251.          In order to implement this daunting
    mandate, Congress "chose to define the waters covered by the Act
    broadly." United States v. Riverside Bayview Homes, Inc., 
    474 U.S. 121
    , 133, 
    106 S. Ct. 455
    , 462, 
    88 L. Ed. 2d 419
    (1985).                      Courts have
    agreed that Congress intended the definition of navigable waters
    under the Act "to reach to the full extent permissible under the
    Constitution."        See United States v. Lambert, 
    695 F.2d 536
    , 538
    (11th Cir.1983).
    The CWA defines "navigable waters" as "waters of the United
    States, including the territorial seas."                  33 U.S.C. § 1362(7).
    This broad definition "makes it clear that the term "navigable' as
    used in the Act is of limited import" and that with the CWA
    Congress    chose     to    regulate    waters   that     would   not       be   deemed
    navigable     under    the        classical   understanding       of    that     term.
    Riverside Bayview 
    Homes, 474 U.S. at 133
    , 106 S.Ct. at 462;                        see
    also United States v. Ashland Oil and Transportation Co., 
    504 F.2d 1317
    , 1325 (6th Cir.1974) (holding that non-navigable tributary of
    navigable     river    is     a     "navigable   water"     under      §    1362(7)).
    Therefore, we can easily dispose of appellants' contention that the
    drainage ditch was not a "navigable water" solely because it was
    not navigable-in-fact.5
    It is by now well established that Congress intended to
    regulate the discharge of pollutants into all waters that may
    eventually lead to waters affecting interstate commerce.                            In
    5
    Appellants' reliance on Lykes Brothers, Inc. v. United
    States Army Corps of Engineers, 
    821 F. Supp. 1457
    (M.D.Fla.1993),
    aff'd, 
    64 F.3d 630
    (11th Cir.1995), is misplaced. That case
    dealt with a provision of the Rivers and Harbors Act, 33 U.S.C. §
    403, which is inapplicable here.
    adopting the present definition of "navigable waters," Congress
    recognized that "[w]ater moves in hydrologic cycles and it is
    essential that discharge of pollutants be controlled at the source.
    Therefore, reference to the control requirements must be made to
    the navigable waters, portions thereof, and their tributaries."
    S.Rep. No. 92-414, at 77 (1972), reprinted in, 1972 U.S.C.C.A.N.
    3668, 3742-43. In accordance with this legislative intent, EPA has
    defined "waters of the United States" to include tributaries to
    waters that "may be susceptible to use in interstate or foreign
    commerce,"    40   C.F.R.   §   230.3(s),6   and   courts   repeatedly   have
    6
    40 C.F.R. § 230.3(s) provides:
    The term "waters of the United States" means:
    (1) All waters which are currently used, or were used
    in the past, or may be susceptible to use in interstate or
    foreign commerce, including all waters which are subject to
    the ebb and flow of the tide;
    (2) All interstate waters including interstate
    wetlands;
    (3) All other waters such as intrastate lakes, rivers,
    streams (including intermittent streams), mudflats,
    sandflats, wetlands, sloughs, prairie potholes, wet meadows,
    playa lakes, or natural ponds, the use, degradation or
    destruction of which could affect interstate or foreign
    commerce including any such waters:
    (i) Which are used or could be used by interstate
    or foreign travelers for recreational or other
    purposes; or
    (ii) From which fish or shellfish are or could be
    taken and sold in interstate or foreign commerce; or
    (iii) Which are or could be used for industrial
    purposes by industries in interstate commerce;
    (4) All impoundments of waters otherwise defined as
    waters of the United States under this definition.
    (5) Tributaries of waters identified in paragraphs (1)
    recognized    that    tributaries    to   bodies   of   water    that    affect
    interstate commerce are "waters of the United States" protected by
    the CWA. See, e.g., United States v. Texas Pipe Line Co., 
    611 F.2d 345
    , 347 (10th Cir.1979) (tributary to navigable river);                Ashland
    
    Oil, 504 F.2d at 1324
    (tributary that eventually flowed into river
    that was navigable-in-fact);          State of Georgia v. City of East
    Ridge, 
    949 F. Supp. 1571
    , 1578 (N.D.Ga.1996) (unnamed tributary of
    interstate creek);         United States v. Saint Bernard Parish, 
    589 F. Supp. 617
    , 620 (E.D.La.1984) (canal flowing into wetland).
    There is no reason to suspect that Congress intended to
    regulate     only    the   natural   tributaries   of   navigable       waters.
    Pollutants are equally harmful to this country's water quality
    whether they travel along man-made or natural routes.               The fact
    that bodies of water are "man-made makes no difference....                That
    the defendants used them to convey the pollutants without a permit
    is the matter of importance."             United States v. Holland, 
    373 F. Supp. 665
    , 673 (M.D.Fla.1974);           see also Leslie Salt Co. v.
    United States,       
    896 F.2d 354
    , 358 (9th Cir.1990) (noting that
    protection of the CWA "does not depend on the how the property at
    issue became a water of the United States"), cert. denied, 
    498 U.S. 1126
    , 
    111 S. Ct. 1089
    , 
    112 L. Ed. 2d 1194
    (1991).                  Consequently,
    courts have acknowledged that ditches and canals, as well as
    streams and creeks, can be "waters of the United States" under §
    1362(7).   See, e.g., United States v. Velsicol Chemical Corp., 
    438 F. Supp. 945
    , 947 (W.D.Tenn.1976) (sewers that lead to Mississippi
    River);    
    Holland, 373 F. Supp. at 673
    (mosquito canals that empty
    through (4) of this section;         ...
    into bayou arm of Tampa Bay).
    Likewise,     there    is    no   reason   to   suspect     that   Congress
    intended to exclude from "waters of the United States" tributaries
    that       flow   only       intermittently.      Pollutants         need   not   reach
    interstate bodies of water immediately or continuously in order to
    inflict serious environmental damage.7                As the Tenth Circuit noted
    in Texas Pipe Line, "[i]t makes no difference that a stream was or
    was not at the time of the spill discharging water continuously
    into a river navigable in the traditional 
    sense." 611 F.2d at 347
    .
    Rather, as long as the tributary would flow into the navigable body
    of water "during significant rainfall," it is capable of spreading
    environmental damage and is thus a "water of the United States"
    under the Act. Id.;             see also Quivira Mining Co. v. United States
    Environmental Protection Agency, 
    765 F.2d 126
    , 130 (10th Cir.1985)
    (upholding regulation because "during times of intense rainfall,
    there       can   be     a    surface   connection"        between    tributary     and
    navigable-in-fact streams), cert. denied, 
    474 U.S. 1055
    , 
    106 S. Ct. 791
    , 
    88 L. Ed. 2d 769
    (1986);              United States v. Phelps Dodge Corp.,
    
    391 F. Supp. 1181
    , 1187 (D.Ariz.1975) ("waters of the United States"
    include "normally dry arroyos" from which water could flow to
    public waters).
    With these principles in mind, we turn to the evidence
    presented in this case concerning the drainage ditch between
    Ingraham      and      Commerce    Streets.      As   Cherokee       was    discharging
    pollutants into the storm sewer system on April 25, 1990, a light
    7
    As the court noted in Ashland Oil, the government need not
    prove that the pollutant actually reached the navigable body of
    
    water. 504 F.2d at 1329
    .
    flow was traveling from the sewer drain into the open drainage
    ditch that connected Ingraham and Commerce Streets.               The flow
    continued northward in this ditch until it reached Commerce Street,
    where it passed underneath the street and into a drainage canal
    that ran parallel to Commerce Street.        The sewer, the ditch, and
    the canal were all part of a storm drainage system that was
    designed to discharge storm water into Tampa Bay. During heavy
    rainfall and during high tide,8 water flows from the drainage ditch
    connecting Ingraham and Commerce Streets into the Commerce Street
    drainage canal, which empties into Picnic Island Creek, a tributary
    to Tampa Bay.
    We hold that this evidence is sufficient to establish that the
    drainage ditch into which Cherokee discharged its pollutants is a
    tributary of Tampa Bay and is thus a "water of the United States"
    under § 1362(7).      To hold otherwise and to allow polluters to
    contaminate    this   drainage   system   would   defeat   the   intent   of
    Congress and would jeopardize the health of our nation's waters.
    Appellants also contend, without any supporting case law,
    that the CWA's definition of pollutant is unconstitutionally vague
    because it does not provide someone discharging petroleum-based
    products with fair notice that this behavior is prohibited.               A
    statute is not unconstitutionally vague as long as it "define[s]
    the criminal offense with sufficient definiteness that ordinary
    people can understand what conduct is prohibited and in a manner
    that does not encourage arbitrary and discriminatory enforcement."
    8
    At high tide, water reached approximately the half-way
    point of the ditch between Commerce and Ingraham Streets.

    103 S. Ct. 1855
    , 1858, 
    75 L. Ed. 2d 903
    (1983). We review the CWA's definition of pollutant in
    light of the particular facts of this case.           See United States v.
    Waymer, 
    55 F.3d 564
    , 568 (11th Cir.1995), cert. denied, --- U.S. --
    --, 
    116 S. Ct. 1350
    , 
    134 L. Ed. 2d 519
    (1996) (noting that vagueness
    challenges that do not involve the First Amendment are examined in
    light of facts before the court).
    Section 1362(6) defines pollutant as:
    dredged spoil, solid waste, incinerator residue, sewage,
    garbage, sewage sludge, munitions, chemical wastes, biological
    materials, radioactive materials, heat, wrecked or discarded
    equipment, rock, sand, cellar dirt and industrial, municipal,
    and agricultural waste discharged into water.
    Although this definition of pollutant is broad, it is not unduly
    vague.   The liquid discharged by the Cherokee truck had been used
    as a cleaning agent for an underground storage tank at a gas
    station and was described as having a strong petroleum odor and a
    dirty, oily appearance.      Given these facts, we do not hesitate to
    conclude   that   an    ordinary    person   should   have   been   able   to
    understand that the petroleum-based, sludge-like substance was
    industrial waste within the meaning of the Act. Because the statute
    provided the Eidsons with adequate notice that their conduct was
    prohibited, we reject appellants' constitutional challenge.9
    B. Counts II-IV:       Mail Fraud
    9
    Appellants also contend that the Act is unduly vague
    because it does not specify what content level of petroleum would
    make a discharged liquid a pollutant. The CWA prohibits "the
    discharge of any pollutant." 33 U.S.C. § 1311(a) (emphasis
    added). Again, we find the Act broad rather than vague.
    Considering the sludge-like qualities of the liquid discharged by
    Cherokee, appellants cannot reasonably contend that the statute
    did not provide them with adequate notice that the discharge was
    prohibited.
    Appellants also contend that there was insufficient evidence
    to support their convictions for mail fraud.               In order to prove a
    violation of 18 U.S.C. § 1341, the government must establish that
    appellants:    (1) intentionally participated in a scheme to defraud
    or to obtain money by fraudulent pretenses and representations;
    and (2) used the United States mails to further that scheme.
    United States v. Wingate, 
    997 F.2d 1429
    , 1433 (11th Cir.1993).
    Appellants    argue     that    the    government    failed   to    establish    a
    fraudulent scheme because there was no evidence that they made
    false representations to their customers.                Based on a thorough
    review of the record, we find ample evidence to support appellants'
    mail fraud convictions.
    A scheme to offer services in exchange for a fee, with the
    intent not to perform those services, constitutes a fraudulent
    scheme under § 1341.           United States v. Paccione, 
    949 F.2d 1183
    ,
    1196 (2d Cir.1991), cert. denied, 
    505 U.S. 1220
    , 
    112 S. Ct. 3029
    ,
    
    120 L. Ed. 2d 900
    (1992).         Upon instructions from Charles and Sandra
    Eidson, Cherokee representatives regularly informed prospective
    customers that Cherokee had proper licenses and permits to dispose
    of wastewater.     Cherokee documents displayed permit numbers and
    Cherokee contracted to dispose of wastewater in accordance with all
    applicable     laws,     codes,       and   regulations.       Despite       these
    representations, Charles and Sandra Eidson instructed Cherokee
    employees to dump the collected industrial wastewater on the ground
    at and around the Cherokee facility in direct violation of their
    operating     permits     and      applicable       environmental     laws     and
    regulations.    We hold that this evidence is sufficient to support
    appellants' mail fraud convictions.10
    C. Sentencing Issues
    Appellants also raise a number of claims regarding their
    respective sentences. We review the factual findings of a district
    court at sentencing for clear error, and review its interpretation
    of the Sentencing Guidelines de novo.        United States v. Holland,
    22 F.3d 1040
    , 1045 (11th Cir.1994), cert. denied, --- U.S. ----, 
    115 S. Ct. 898
    , 
    130 L. Ed. 2d 782
    (1995).
    With respect to their count one convictions, appellants first
    challenge the district court's decision to increase their offense
    levels pursuant to U.S.S.G. § 2Q1.2(b)(1)(A)(1993).            That section
    provides for a six-level increase if the "offense resulted in an
    ongoing, continuous or repetitive discharge."            Appellants contend
    that there was only one discharge into waters of the United States.
    However,     Sandra   Eidson   admitted   that   there   had   been   another
    discharge into the sewer approximately one week before the April
    25, 1990 discharge.      We find that this admission is sufficient to
    support an offense-level increase under § 2Q1.2(b)(1)(A).                 See
    United States v. Catucci,

    presented no evidence to support these claims. In a letter dated
    September 17, 1992, the prosecutor informed appellants that they

    seized documents before trial.
    (4th Cir.1993) (two separate incidents sufficient to support upward
    adjustment under analogous provision of § 2Q1.3(b)(1)(A)).
    Appellants also contend that the district court erred in
    imposing    an     offense-level       increase      pursuant     to    U.S.S.G.    §
    2Q1.2(b)(3)(1993).         Section 2Q1.2(b)(3) provides for a four-point
    increase     if    "cleanup     required       a   substantial         expenditure."
    Application Note 7 states that this section governs cases where
    "cleanup at substantial expense has been required."                      U.S.S.G. §
    2Q1.2 comment. (n. 7).          Appellants argue that because both the
    guideline and the application note refer to cleanups in the past
    tense, the district court erred in basing the upward adjustment on
    an estimate of future cleanup costs.
    Section 2Q1.2(b)(3) makes a defendant's sentence dependant on
    the nature of contamination caused by the environmental offense.
    The costs of cleanup are but one method a court can use to measure
    the   seriousness     of    contamination.           Section    2Q1.2(b)(3)      also
    provides for an offense-level increase if the discharge resulted in
    "disruption of public utilities or evacuation of a community."                      We
    find it unlikely that Congress intended that a defendant guilty of
    serious    environmental       contamination       should      receive    a   lesser
    sentence    merely    because        the   conviction     occurred      before     the
    appropriate environmental agency could undo the harm.                         Such a
    reading    would    thwart    Congress's       intent    to    punish    defendants
    according to the level of environmental degradation caused by their
    criminal offenses.
    Moreover,    in     this     case,   the      Florida    Department       of
    Environmental Regulation already had incurred significant cleanup
    costs at the time of sentencing.         It had conducted a preliminary
    site survey and liquid sample retrieval of Cherokee's site, which
    indicated   that    Cherokee's   illegal   discharge   had   caused    gross
    contamination of the surficial sediments and the surficial aquifer.
    The costs incurred for this preliminary examination, which exceeded
    thirty thousand dollars, are properly considered cleanup costs.
    See United States v. Bogas, 
    920 F.2d 363
    , 369 (6th Cir.1990)
    (holding that cleanup expenditures under § 2Q1.2(b)(3) include site
    testing, studies, and other indirect costs of site remediation).
    Based   on    its   preliminary   investigation,   the   department
    concluded that complete cleanup of the Cherokee site would cost
    several hundred thousand dollars.        Because this estimate was based
    on a thorough preliminary examination of the site, we are satisfied
    that it represents an accurate and reliable measure of the degree
    of   contamination    caused   by   appellants'   discharges.     We    also
    conclude that the contamination in this case was quite serious.
    Accordingly, we hold that the preliminary investigation and cleanup
    estimate provide an adequate basis for an upward adjustment under
    § 2Q1.2(b)(3).       See 
    Bogas, 920 F.2d at 369
    (noting that the
    government need not provide an exact accounting of cleanup costs in
    order to demonstrate "substantial expenditure" under this section);

    Charles Eidson also contends that the district court erred in
    imposing an offense-level increase under U.S.S.G. § 3B1.1(a)(1993)
    for his role as an "organizer or leader of a criminal activity that
    involved five or more participants or was otherwise extensive."11
    The district court increased Eidson's offense level by four points
    for his role in the CWA violation and for his role in the mail
    fraud scheme because it found that Cherokee employed an average of
    five or more persons.     Eidson claims that the district court erred
    because there was insufficient evidence to conclude that these
    employees were participants in the illegal discharge and fraudulent
    scheme.
    In determining the number of participants in a criminal
    activity, courts count all individuals, including the defendants,
    who were criminally responsible for the commission of the offense
    even though they might not have been convicted.           United States v.
    Holland, 
    22 F.3d 1040
    , 1045 (11th Cir.1994), cert. denied, --- U.S.

    (1995);              U.S.S.G. § 3B1.1
    comment. (n. 1).      With respect to the mail fraud counts, there is
    ample evidence to support the district court's finding. Appellants
    regularly instructed Cherokee employees to dump the wastewater on
    the ground and to refer fraudulently to the ground as "Tank 8".
    They also instructed employees to inform prospective customers that
    Cherokee had all the necessary permits and licenses.          Two Cherokee
    employees     testified   that   they   knowingly    participated    in   the
    fraudulent scheme and also referred to other drivers and a yard
    foreman     who   participated   in   the   scheme   to   defraud   Cherokee

    this section.
    customers.   Based on this record, we conclude that the district
    court did not clearly err in increasing Eidson's offense level for
    his mail fraud convictions.
    The district court's upward adjustment for the CWA conviction
    presents a more difficult question.    As we noted in United States
    v. Rodgers, a sentencing court cannot enhance an offense level
    merely because a defendant "acted with others for the other charges
    against him."   
    951 F.2d 1220
    , 1221 (11th Cir.)(citing
    United States
    v. Tetzlaff, 
    896 F.2d 1071
    , 1074 (7th Cir.1990)), modified in part,
    
    972 F.2d 1253
    (11th Cir.1992).   In other words, a court should only
    consider "conduct immediately concerning" the offense of conviction
    in determining an adjustment under § 3B1.1(a).      See 
    Holland, 22 F.3d at 1046
    n. 10.12 For purposes of the offense-level increase for
    the CWA conviction, we will not consider the number of participants
    involved in the mail fraud scheme because those discharges did not
    "immediately concern" the CWA offense.
    Both appellants and the driver of the Cherokee truck can be
    classified as participants in the April 25 discharge.   There is no
    12
    Rodgers apparently was based on the pre-November 1990
    version of § 3B1.1 that did not include the introductory
    commentary directing courts to consider relevant conduct pursuant
    to § 1B1.3 in determining a defendant's role in the offense.
    Nevertheless, its holding appears to continue to govern cases
    dealing with the post-amendment version of § 3B1.1. See 
    Holland, 22 F.3d at 1046
    n. 10 (applying 1991 version and distinguishing
    Rodgers ). In the event that the November 1990 amendment somehow
    altered the law of this circuit in such a way that would increase
    Eidson's punishment, it would not apply because Eidson committed
    this offense before the commentary became effective. See United
    States v. Wilson, 
    993 F.2d 214
    , 216 (11th Cir.1993) ("We apply
    the version of the sentencing guidelines and commentary in effect
    on the date of sentencing, unless a more lenient punishment would
    result under the guidelines version in effect on the date the
    offense was committed.") (citations omitted).
    factual    basis     in    the    record,     however,     to     identify     other
    participants in this particular offense.                   None of the former
    Cherokee employees who testified at trial were employed at the time
    of this illegal discharge and none of them testified about other
    discharges    into    "waters     of   the   United   States."          Although     a
    bookkeeper presumably prepared a manifest and invoice for this
    delivery, there is no reason to believe that he or she was aware
    that the pollutant was dumped into a "water of the United States"
    rather    than   onto     the    Cherokee    lot   with    most    of   the    other
    pollutants.      Therefore, we conclude that there was insufficient
    evidence in the record to conclude that the illegal discharge of a
    pollutant into "waters of the United States" involved five or more
    participants.
    Section 3B1.1 allows for an offense-level increase, however,
    on the alternative ground that the criminal activity was "otherwise
    extensive."      Although the presentence report, adopted by the
    district court, did not specify that it found the criminal activity
    "otherwise extensive," we examine the record to determine if such
    a finding would have been justified.
    Neither the Guidelines nor the cases interpreting § 3B1.1
    provide a precise definition of "otherwise extensive."                        Such a
    finding depends on a number of factors including "the length and
    scope of the criminal activity as well as the number of persons
    involved." 
    Holland, 22 F.3d at 1046
    (noting that criminal activity
    that extended over three years and involved the assistance of
    several   individuals      raised      a   question   as   to     whether     it   was
    "otherwise extensive");          see also United States v. Rodriguez, 
    981 F.2d 1199
    , 1200 (11th Cir.) (finding drug operation that extended
    from Colombia to New York and involved 100 kilos of cocaine
    "otherwise extensive"), cert. denied, 
    508 U.S. 955
    , 
    113 S. Ct. 2455
    ,
    
    124 L. Ed. 2d 671
    (1993).13
    The district court made no such factual findings in this
    case.       The record indicates only that one other similar discharge
    into a "water of the United States" occurred a week before the
    April 25 discharge. We conclude that this evidence is insufficient
    to    establish        that    the   criminal     activity     involved       in   the   CWA
    conviction was "otherwise extensive."
    Finally, appellants challenge the district court's factual
    finding that the loss caused by their fraudulent scheme exceeded
    two hundred thousand dollars.              Based on this finding, the district
    court increased their offense levels by eight points pursuant to
    U.S.S.G. § 2F1.1(b)(1)(I)(1993).                 Again, the district court merely
    adopted the factual findings contained in the presentence report
    and    made       no   specific      factual    findings   to       support   the   upward
    adjustment.14
    The    presentence       report,    without    any      underlying      factual
    support, concluded that Cherokee had fraudulently billed Mobil Oil,
    Diamond       Products        Company,    and    the   B   &    E    Equipment      Company
    13
    "In assessing whether an organization is "otherwise
    extensive,' all persons involved during the entire course of the
    offense are to be considered. Thus, a fraud that involved only
    three participants but used the unknowing services of many
    outsiders could be considered extensive." U.S.S.G. § 3B1.1
    comment. (n. 3).
    14
    The transcript for Sandra Eidson's sentencing hearing is
    not part of this record on appeal. Nevertheless, the order of
    judgment indicates that the district court adopted the
    presentence report's factual findings.
    $215,427.22 for services that were not rendered.          Apparently, the
    presentence report incorrectly interpreted a government chart,
    entitled "Waste Water Transactions of Cherokee Oil, Inc.1985-1991,"
    which valued Cherokee's total wastewater revenues at $215,427.22.15
    Although losses incurred by other Cherokee customers are includable
    in a § 2F1.1 calculation, there must be some factual basis for the
    conclusion that these losses were the result of fraud.                   See
    U.S.S.G. § 2F1.1 comment. (n. 7) (1993) ("[L]oss is the value of
    money, property, or services unlawfully taken.") (emphasis added).
    Former Cherokee employees testified that Cherokee regularly
    billed customers for wastewater disposal that it did not conduct
    from May 1990 to November 1991.        There was no factual basis in the
    record, however, to conclude that the wastewater disposal practices
    of Cherokee from 1986 to May 1990 were equally fraudulent.               The
    only witness to testify about Cherokee's practices before 1990,
    Albert Martell, worked with the company for only four months in
    1986 and specifically disavowed any knowledge as to how wastewater
    pickups were disposed.16 Based on this record, we conclude that the
    district   court   committed   clear    error   in   concluding   that   the
    fraudulent scheme caused over two hundred thousand dollars in
    15
    This chart was offered as evidence at trial by the
    government, but was rejected by the district court on relevancy
    grounds. Its exclusion at trial does not, however, preclude its
    use at sentencing. See U.S.S.G. § 6A1.3 (1991) (noting that at
    sentencing district court may consider reliable information
    without regard to its admissibility at trial).
    16
    Martell did indicate that in his four months as bookkeeper
    he never came across any bills that Cherokee paid for proper
    disposal of wastewater. However, this fact standing alone cannot
    support the inclusion of all gross wastewater revenues from 1986-
    1990.
    losses.17
    III. Conclusion
    We AFFIRM appellants' convictions, VACATE their sentences, and
    REMAND the case to the district court for resentencing.
    17
    The government argues that this deficiency in proof can be
    remedied by contemplating the costs that the defrauded companies
    may incur if they are required to contribute to cleanup costs
    pursuant to Section 107 of the Comprehensive Environmental
    Response, Compensation and Liability Act, 42 U.S.C. § 9607. The
    presentence report, however, does not reference the potential
    liability of former Cherokee customers. In the event such
    liability could be properly considered under this section, we
    conclude that at present it is too speculative to support an
    enhancement.
