Opinion

ORDER AND JUDGMENT *

EBEL, Circuit Judge.

Defendant-Appellant David James Yarbrough appeals the district court’s decision denying his motion for a new trial, see Fed.R.Crim.P. 33(a), following a jury’s convicting him on seven counts of making false statements in violation of 18 U.S.C. § 1001. 1 Having jurisdiction to consider *149 this appeal under 28 U.S.C. § 1291, we AFFIRM. 2

I. Facts.

The United States Army stores and destroys chemical weapons at the Deseret Chemical Depot (Depot) near Tooele, Utah. Within the Depot, there is an area called the chemical agent munitions demilitarization system (CAMDS), which “is a research and development facility where ... tests [are done] to prove out the processes and the procedures that [will be] use[d] to destroy the chemical munitions.” The CAMDS facility includes a chemical test facility, where toxic chemical tests are conducted, and a filter farm, through which air forced from, among other places, the chemical testing facility, is filtered before it is released back into the atmosphere outside the controlled CAMDS buildings.

Depot workers, especially those working in the CAMDS, as well as the general public, are protected from the toxic chemicals being tested, in part, by an automated continuous air monitoring system (ACAMS). That system involves a series of machines, or ACAMS units, that continuously monitor the air for any trace of toxic chemicals. If these units do detect the presence of a toxic chemical, the machines will set off alarms to warn the workers.

The ACAMS’s accuracy and reliability is monitored through baseline testing procedures. “A baseline test is a quality assurance system that [CAMDS] ha[s] to make sure that all of the A.C A.M.S. units, the monitoring systems in a particular facility work together and ... work the way that they are supposed to work.” Baseline testing involves an operator or mechanic injecting a diluted amount of a particular toxic chemical substance into an ACAMS unit and then recording the machine’s reading. This is known as an agent or hazard challenge. If the unit is functioning properly, the machine should indicate the presence of the toxic substance the operator injected.

There are three different types of baseline tests. First, when a monitoring system is installed, there is a thirty-day initial baseline test. This case does not involve initial baseline testing.

After the monitoring system is operational, there is continuous baseline testing. To conduct this continuous testing, operators challenge each ACAMS unit daily with a diluted solution of the appropriate toxic chemical. The operator’s first injection into a particular machine is known as the first shot. Once the operator makes the injection, he reads the ACAMS unit’s digital reading and records it on the log sheets in the logbook kept with that unit. An optimal reading would be 1.0. But a passing score will fall between .75 and 1.25. Such a passing score indicates that the ACAMS unit is functioning properly.

If the first shot passes, it is recorded on the log sheets as a PI shot and no further action is taken. If the first shot instead fails, it is recorded on the log sheet as an *150 FI shot, the mechanic adjusts the machine, and records the adjustments he makes in the comments section of the log sheet. Later, the operator fills out a separate form known as a failure report. After making the needed adjustments, the operator injects the machine a second time. This second shot is usually a passing shot, 3 and would be recorded on the log sheet as P2.

When conducting a continuing baseline test, operators always record the results of the first shot, regardless of whether that first shot produced a passing or a failing score. The first shot is the most important shot because its results indicate how well the machine has functioned during the preceding twenty-four hours between tests.

The test data is collected in three ways. First, operators record the results of their hazard challenges on the log sheets found in a log book kept with each ACAMS unit. Secondly, the units themselves record the results on a strip of paper known as a strip chart. And thirdly, each unit is connected to a computer which collects readings from all the ACAMS machines.

The results of the continuous baseline testing are then collected and analyzed every four weeks. A statistician takes the readings from the log sheets and feeds those into a computer program. The statistician specifically enters the results of each unit’s daily first challenge and, “if it failed on the first shot, then [the statistician] would also enter the second passing challenge” for that day. Using that data, the statistician generates a report, known as an INACCMO report. “The INACCMO report primarily looks at the first shot, so in the statistics that are calculated, the second shot is not looked at. It’s all based on the first shot.” That report is disseminated to the Depot’s upper level supervisors, as well as “various [state and federal] regulatory agencies,” “the program manager for chemical demilitarization out of Aberdeen Proving Ground” in Maryland (PMCD), which is the Depot’s “higher headquarters, ... the Center for Disease Control,” the Department of Health and Human Services and the Army.

The third type of baseline test, the testing specifically at issue in this case, is a ten-day recertification baseline. Recertification testing is required when an ACAMS unit has not been in operation for a certain amount of time, or when the facility is changing over from operations involving one toxic chemical agent to those involving another chemical agent. Except for its length, recertification baseline tests are conducted the same way that continuous baseline tests are conducted, with daily hazard challenges to each ACAMS unit. The readings are again recorded on the log sheets and, at the end of the ten-day testing period, the readings are fed into the computer program to produce an INACCMO report. The facility cannot begin any new project until the ACAMS passes the recertification test.

Defendant Yarbrough was the “division chief for the monitoring division on the Depot. He was responsible for supervising the technicians in the performance of their duty of maintaining these [air monitoring] systems.” Although Yarbrough had held this position for eight or nine years, he was not acting as division chief during the first half of 2002. During Yarbrough’s absence, Patti King and another mechanic foreman had taken over Yarbrough’s duties. Yarbrough resumed his duties as monitoring system chief on June 20, 2002.

*151 At this time, the CAMDS facility was in the process of conducting recertification baseline tests because that facility was changing over to operations involving a new toxic agent.
