Rоbert Cyphers pleaded guilty to charges of submitting false reports in violation of 18 U.S.C. § 1001. He challenges his sentence, contending that the district court erred by adjusting his offense level upward based upon a finding that he supervised others who participated in the offense. Cyphers contends that the adjustment is not appropriаte because the others were not “participants” in the same crime that he committed. We conclude that the adjustment was appropriate, and accordingly, we affirm.
FACTS AND PRIOR PROCEEDINGS
Cyphers was licensed to clean up environmental contamination from leaking underground gasoline and other fuel storage tanks. Such cleanups are required by federal law, 42 U.S.C. §§ 6901-92k, but the program is implemented by the states. Operating through various companies, Cyphers contracted to remove and replace leaking tanks, conduct sоil and water sampling and lab testing, remove contaminated soil and water, and submit required reports to the státе. Cyphers, in fact, submitted false reports, some from labs that did not exist, others forged on legitimate laboratоry letterhead. Cyphers also directed his employees to take samples from areas that would shоw sites to be free from contamination, when they were not. In one case, he directed his employees to drain contaminated water from holding tanks directly *1363 into the storm sewers during the night without sampling, testing, or obtaining а permit.
Cyphers was charged with fifty-one, counts of submitting false reports concerning cleanup sites in Oregon, but ultimately pleaded guilty to four counts. At sentencing, the court determined Cyphers’ offense level to be 15, inсluding a two-level upward adjustment pursuant to U.S.S.G. § 3Bl.l(e). The court specifically found that Cyphers supervised employees who “knew and participated in the fraudulent practices at the direction of the defеndant.”
DISCUSSION
The Sentencing Guidelines provide for adjustments to a defendant’s offense level “based upon the rоle the defendant played in committing the offense.” U.S.S.G. Opening Commentary to Part B — Role in the Offense. The district court applied section 3Bl.l(c), which provides for a two-level increase when defendant is determinеd to be “an organizer, leader, manager, or supervisor in any criminal activity.” Although that section does nоt expressly require that there be a “participant” in the crime, we have held that there must be at least one participant other than the defendant.
See United States v. Anderson,
Cyphers contends that his employees did not partiсipate in the crime charged — submitting false statements — thus, they are not “criminally responsible for the commissiоn of the offense.” The government responds that the 1990 amendment to the introductory commentary permits sentencing courts to examine a defendant’s supervisory role over others for all relevant conduct, not limited to the elements of the crime of conviction. We agree. “The 1990 amendment to the introductоry commentary explains that the adjustment for role is based on all relevant conduct, as defined in U.S.S.G. § 1B1.3, and not solely on the defendant’s role in the offense of conviction.”
United States v. Savage,
We do not agree with Cyphers that
United States v. Lewis,
The district court here specifically found that Cyphers’ employees were knowing participants. Indеed, the district court expressly found that the “employees knew of and participated in the fraudulent practices” and did so “at the direction of the defendant.” Moreover, each employee tеstified before a grand jury that he was aware that his activities were unlawful. One admitted that it was “common knowledge in the company as to what was going on.” Another acknowledged that it was clear that Cyphers told thеm “to take samples in one fashion and report that they were taken in another way.” The third employеe agreed that his activities were suspicious, and that “shady business practices came after we took the things back to the office and Bob [Cyphers] actually altered the paperwork.” This is simply not a еase where the participants were unknowingly duped into the scheme.
*1364 In sum, we conclude that for purposes of section 3Bl.l(c), a district court may look to relevant conduct in determining whether a defendant’s base offense level should be adjusted. Here, it is sufficient .that the district court found that Cyphers supervised employees who “knew and participated in the fraudulent practices at the direction of the defendant.”
AFFIRMED.
