Before BIRCH and DUBINA, Circuit Judges, and HANCOCK*, District Judge.

PER CURIAM:

       *
          Honorable James H. Hancock, U.S. District Judge for the Northern District of Alabama,
sitting by designation.
      Alfred R. Taylor, Christian A. Hansen, and Randall W. Hansen appeal their

convictions for conspiracy to commit environmental crimes, violating the Clean

Water Act, violating the Resource Conservation and Recovery Act, and violating

the Comprehensive Environmental Response, Compensation, and Liability Act.

On appeal, they each assert several alleged trial and sentencing errors. Finding no

merit to their claims, we AFFIRM.

                               I. BACKGROUND

        Christian Hansen (“Hansen”) founded the Hanlin Group (“Hanlin”) in

 1972, and served as its President, Chief Executive Officer, and Chairman of the

 Board until early April 1993. R19-160. Hanlin operated an industrial plant in

 Brunswick, Georgia, as LCP Chemicals-Georgia (“LCP”), R21-41, and Hansen

 served as the plant manager for approximately two months in 1993. R19-166-67.

 Randall Hansen (“Randall”), Hansen’s son, was hired as an executive vice

 president in 1992. R21-193. He became Chief Executive Officer in April 1993

 and served in that capacity until November 1993. R21-195. Alfred Taylor

 (“Taylor”) began working for LCP in 1979, and became the Brunswick

 operations manager in 1991. R21-243-44. He served as plant manager from

 February until July 1993. R21-244-45.




                                          2
           Hanlin purchased the Brunswick plant in 1979.1 R21-41. The plant,

 which is on a site adjacent to tidal marshes and Purvis Creek, operated

 continuously year-round, manufacturing caustic soda, hydrogen gas, hydrochloric

 acid, and chlor-alkali bleach. About 150 people worked at the plant in two “cell

 buildings” or “cellrooms.” Each cellroom was about the size of a football field

 and contained fifty mercury “cells,” the units used to produce the bleach, soda,

 gas, and acid ultimately sold by LCP. R8-200-2. “The production process

 generated hazardous wastes, including elemental mercury, mercury-contaminated

 sludge (or “muds”),2 wastewater, chlorine contaminated wastewater, and



       1
          The site has been used by various companies for 50 years, and was unregulated by any
environmental regulations until the 1970s. The site was operated as an oil refinery from 1919 to
1937 by Atlantic Richfield [ARCO], as a manufacturing site from 1937 to 1955 by Dixie Paint
Company, and as a chlor-alkali facility from 1955 to 1979 by Allied Chemical. R16-85-86. Allied
Chemical used graphite anodes impregnated with PCBs during the chlor-alkali process, and buried
the contaminated anodes on the site. R21-54, 229. It is now a Superfund site, and is being cleaned
at the expense of the government and these earlier owners.
       2
         In a memorandum regarding mercury consumption, dated 4 October 1993, Taylor noted
that mercury “[c]onsumption was particularly high in 1988" and for 1990-1993. Govt. Ex. 19-5.
An attachment showed “excess” mercury from consumption of 243,102 pounds from 1986 to 1993.
Id.
        The “mud” was spread onto the cellroom floors to dry, the mercury was recovered from
underneath and on top of the mud, and the mud was put into drums for disposal. R19-190-93. When
the wastewater covered the floors, the mud could not be stored until the water receded and it was
dried. Id. at 191. The drums were stored underneath the cellrooms. R20-62. The drums were
labeled and dated when the mud was first put into the drum “because [the plant] only had a ninety-
day storage period under [the] permit.” Id. at 62-63. There were “times” when the mud was
“redrumed” and again labeled for another ninety-days. Id. Hanson testified that Taylor was aware
of the muds in the drums. Id. at 62.
        At Taylor’s direction, mud that accumulated in the wastewater stored in tank railcars was
“drained off to the wastewater treatment area.” R20-356-57.

                                                 3
extremely caustic wastes with high pH values.” Id. at 2-3; R16-112-14. The

wastes were subject to various environmental regulations, including wastewater

limitations on pH, mercury, and chlorine set forth in LCP’s National Pollutant

Discharge Elimination System (“NPDES”), and to regulations of the Resource

Conservation and Recovery Act (“RCRA”), 42 U.S.C. § 6928(d)(2).

        LCP constructed a wastewater treatment system in 1989 and 1990, and was

allowed, by NPDES permit, to discharge the treated wastewater into Purvis

Creek. Although LCP represented that the system would have a continuous

treatment capacity of 70 gallons per minute in the project description submitted

to the Georgia EPD, Govt. Ex. 10-3b at SW5 00001807, the filtration and storage

systems installed had a capacity of only 35 gallons per minute, R20-20-21; Govt.

Ex. 1-12. LCP did not notify the Georgia EPD of the lower wastewater treatment

capacity. R20-290. The plant was authorized to store wastewater which was

awaiting treatment in the wastewater treatment plant on the floor of the

cellrooms. R16-118; R21-145, 161. The cellrooms were constructed of concrete,

with a downward slope which diverted the wastewaters to a sump3 and then to the

wastewater treatment holding tanks. R19-33-34. If the cellroom became

incapable of holding the wastewater, it leaked out onto the ground and



    3
        A sump is a hole with a grate over it. R19-34

                                              4
 accumulated in a lake. R16-131-32. LCP also used “Bunker C” oil tanks for

 additional wastewater storage. R19-291; R20-42-45. Due to accidental spills,

 bleach sometimes accumulated on the Cellroom 1 floor. R19-258. During the

 early 1990s, the maintenance at the plant began deteriorating. R20-177, 179.

 Replacement parts were not made available, and wastewater began accumulating

 around the plant. Id.

           The operations were subject to Occupational Safety and Health

 Administration (“OSHA”) regulations for the protection and safety of the

 employees. The workers exposed to mercury vapors in the mercury cell process

 were provided with liquids to drink in order to stay hydrated and deplete the

 mercury, and their exposure was periodically monitored through an extensive

 mercury urinalysis procedure. R20-145-46; R21-251-52. Employees who

 showed exposure to excess mercury were not allowed to return to work until they

 were seen by a medical physician, and were then relocated to other plant

 locations away from the mercury cells.4 R20-146, 164-65, 168-69, 174; R21-

 255, 258; R22-12, 24.

           In August 1992, OSHA inspected the plant “due to an employee complaint



       4
          LCP retested and counseled any employee who tested above 150 micrograms per liter, and
employees with a confirmed result above 250 micrograms were removed from further exposure until
their level went below 150. R21-253-55.

                                                5
 about safety hazards associated with water on cell room floors.” Govt. Ex. 10-7i.

 OSHA found this to be a “willful violation and demanded that no employees be

 allowed to work in contact with the water while the equipment was energized,”

 and “forced” LCP “to erect a boardwalk system above the water level around all

 the equipment until the water c[ould] be eliminated permanently.” Id. LCP

 added wooden elevated walkways in the cellrooms to prevent the workers from

 having contact with the water on the floor and to reduce the workers’ risk of

 electrical shock or chemical burns.5 R16-118; R21-145-46, 161. The chemicals

 used in LCP’s operations were very alkaline and caustic and could irritate and

 burn skin.6 R16-93; R19-43, 197; R20-188; R21-263-64. To minimize the

 workers’ risk of skin irritations and burns, LCP held routine safety meetings,

 encouraged and received safety inspections, and provided the employees with



       5
         The water occasionally rose high enough to splash onto or soak the walkways, and they
became slick. R20-181, 322. OSHA also required that LCP utilize a lockout procedure for
 employees to work on a cell or pump because of the potential electrical hazards. R19-45; R20-190.
In the lockout procedure, an operator ensured that the electrical power was shut off before a
mechanic was permitted to begin work. R19-46-47; R20-190, 323.
       6
           One former employee, Duane Lorenzo Carver, testified that he received second and third
degree burns on his thighs from caustic that had soaked through his clothes. R19-182, 197. In
reference to a question regarding the conditions of the cellrooms in 1993, he said that, while digging
out the sump, he misstepped and fell into the sump hole, which was filled with wastewater, “about
chest deep.” R19-201-03, 227-228. Carver said that he showered immediately and suffered minor
burns on his stomach and legs. R19-203, 229. Carver was unable to recall the exact date, and
admitted the accident could have occurred any time between 1987 and 1993. R19-226. Carver
testified that, although the employees were told to report all accidents to management, he did not
report the accident, and thus did not receive any medical attention. R19-230.

                                                   6
 training, protective equipment to preclude skin contact, and first aid stations and

 showers to relieve inadvertent contact. R19-47, 194, 233-34, 246, 300-01; R20-

 170, 181-82, 185, 188, 190-91; R21-249. All employees, including those

 assigned to the cellrooms, were authorized to work elsewhere in the plant if they

 were concerned about their safety. R19-302; R20-186-87, 320-2; R21-156.



       In 1991, LCP’s parent corporation, Hanlin, filed a voluntary bankruptcy

petition with pre-petition obligations exceeding $100 million. R19-119; R21-194.

Shortly thereafter, Randall was hired as an executive vice president of LCP and

charged with “developing the business and financial plans necessary to turn around

the financial condition of the chemical business.”7 R21-193; R16-97. Randall

worked closely with Hanlin’s bankruptcy attorneys, the law firm of McCarter and

English, and the environmental law firm of Decher, Price and Rhoads. R19-140-

43; R21-194, 215.8 Randall also worked closely with LCP’s corporate

environmental manager and site environmental managers. R20-64-65; R21-210,

215. During the bankruptcy proceedings, available funds for maintenance, repair,

and environmental compliance were restricted. R19-50-52. Randall attempted to

           Randall Hansen had worked for Hanlin in a financial capacity from 1986 until 1989.
       8
         During the bankruptcy proceedings, Hanlin set aside seven to ten thousand dollars per day
for professional fees. R19-147.

                                                7
find additional funds by selling excess equipment and reducing the payroll but the

funds remained limited. Id. The ultimate decision-making for all major projects,

capital and extraordinary expenditures, and the sale of assets, were subject to the

approval of the Board and the bankruptcy creditor’s committee and court. R19-

121, 143-47, 174-75; R21-196. Although funds were requested to address the

cellrooms’ wastewater problem, the funds were usually not released. R21-259-60.

       In February 1992, the Brunswick plant manager, James L. Johns, advised

Randall in writing that, without “extensive work,” to keep the wastewater

treatment system operable, they would be unable to “operate the plan for more than

a few days without ‘willfully’ violating EPD regulations which we will not do.”

Govt. Ex. 1-8a at HA 00024857.9 In April 1992, Randall visited the Brunswick

plant and met with plant manager James L. Johns for “an update on regulatory

compliance requirements.” Govt Ex. 10-7b. He indicated that he would provide

guidance on the approval of funds for a study for the NPDES permit, LCP’s

commitment regarding the 1 June 1992 Georgia EPD deadline for cellroom floor

repairs, and the possibility of a study or remediation plan for the “brine

impoundments.” Id. In June 1992, Randall was advised in writing that a


       9
          The memo was addressed “Production Reliability” and noted that “[l]ack of money has
limited the plant production capability and imposed substantial risk on maintaining acceptable
production levels.” Govt. Ex. 1-8a at HA 00024856. The wastewater treatment issues were one of
nine noted problems. Id., HA 00024856 and 57.

                                              8
conference with OSHA on 8 May 1992 noted 26 serious violations and 11 non-

serious violations. Govt. Ex. 10-7d.

       During the summer of 1992, the Brunswick plant management changed.10

R16-104-05. In August 1992, Taylor advised Randall that Brunswick was “unable

to meet current permit limitations,” that he anticipated “more restrictive”

limitations, and that the “[p]erformance of the waste water treatment system [was]

a serious threat to the continued operation of the plant.” Govt. Ex. 1-12. Taylor

said that while the “generation of waste water ha[d] greatly increased due to

leaking brine tanks, [poor condition of the] brine pumps [and] . . . brine filters,

heavy rainfall, the necessity to destroy bleach, and numerous operating problems,”

at the same time the capacity of the wastewater system was limited by the reduced

capacity of the filtration and storage systems, was “further reduced” by the “[l]ack

of maintenance,” and the system was “frequently shut down due to mechanical

problems and operator errors.” Id. In November 1992, Randall visited the

Brunswick plant to interview a candidate for plant manager, and spoke with the

acting manager, Hugh Croom. R19-30. At that time, Croom advised Randall of


       10
            J.L. Johns, the plant manager at the beginning of 1992, retired due to heart problems.
R16-104. During the six month search to replace Johns, Hugh Croom, the plant manager for the
LCP chlor-alkali plant in North Carolina, transferred to Brunswick and acted as plant manager. Id.
at 103-05. Croom returned to the North Carolina plant in January 1993, and admitted that problems
with the wastewater treatment plant and his concerns for maintaining a production rate and for the
safety of the employees and the community contributed to his desire to leave Brunswick. R16-134-
36.

                                                9
problems with the caustic filters and the intentional dumping of caustic on the

cellroom floors by some unknown employee. R19-30-31, 56-58. Croom testified

that Randall “was just as concerned as we were about the problems” and authorized

Croom to hire a task force.11 R19-50, 58.

      In February 1993, LCP offered the plant manager job to Taylor. R21-244.

During his tenure as manager, Taylor stressed safety and strict adherence with

LCP’s training and safety programs, and assured employees the right to refuse to

perform any activity if the employee felt it to be unsafe. R19-302-03. When the

wastewater overran the cellroom berms and streamed outside the building, the

overflow was reported to the EPD and to the LCP Board by letters signed by

Taylor. R20-25-27. The amounts reported in the letters were consistent with the

data that the plant had at that time. R20-27.

      During the spring of 1993, Taylor attended a company meeting with Randall

and Croom in which they discussed the condition of the Brunswick plant and

possible solutions. R19-18-19. Taylor and Croom recommended “either shutting

the plant down or shutting it down long enough to salvage one cellroom and

rebuild the second cellroom, and then starting back up with just one cellroom.”

R19-20, 22. Taylor worked up “the figures and costs” and submitted it to Randall,


      11
           The dumping abated once the task force was hired and the valve area was monitored.
R19-58.

                                             10
but Randall later advised them that “[t]hey won’t let me do it.” R19-22-23, 64. By

letters to EPD, Taylor reported that the plant had exceeded the maximum daily

allowable discharges seventeen times, and explained that the discharges were due

to “heavy rainfall,” “miscommunication between operations supervision,” “a slight

miscalculation,” and “storm, rainfall and process leaks.” Govt. Ex. 10-1d, e, g.

Taylor noted that the “waste water treatment operating efficiency and outfall

discharge” was “positive[ly] affect[ed]” by LCP’s decision not to replace a leaking

brine tank. Govt. Ex. 10-1g.

      In April 1993, the Board of Directors, with the approval of the bankruptcy

court, removed Hansen as Chairman, President, and CEO of Hanlin after he

attempted to expel the outside directors from the board. R19-122-23, 160, 167-68.

The Board and the bankruptcy creditors’ committee asked Randall to serve as

LCP’s interim CEO and Chief Operating Officer [COO]. R19-160; R21-195, 200.

His primary focus was financial and, with the support of the bankruptcy creditors

committee and court, he sought to sell the company to a responsible party who

could operate the business and have the financial resources to deal with the various

environmental conditions. R19-147-48, 164, 174-75; R21-200-01, 219. In this

capacity, Randall received daily reports concerning the Brunswick plant’s

operations and problems. R16-97-98. After Hansen’s removal as CEO, he was no

longer a corporate officer and became a director and employee. R19-136, 160,

                                         11
168. Sometime later, the Board sent Hansen to Brunswick to help run the plant.

R19-166-67.

      Taylor reported five discharge violations in April, and indicated that two

violations were due to a problem in the wastewater treatment system that had been

corrected, one violation was attributable to rainfall, and one violation was due to

leaks which had been repaired. Govt. Ex. 10-1h. Taylor indicated that “[a]n upset

in the wastewater treatment system caused a release of ineffectively treated

wastewater” but that “the discharge was rerouted until the system resumed normal

operation.” Id. Taylor reported 16 discharge deviations in May 1993, which he

indicated were caused by an equipment failure which had been repaired,

“overloading the wastewater treatment system,” and rainfall. Govt. Ex. 10-1i. In

June, Taylor reported 21 excessive discharges which were attributable to “upsets”

and “operational problems” in the wastewater treatment system and equipment

failures. Govt. Ex. 10-1j and 10-1k. Hansen visited the plant in late June and

began working with Taylor. R19-167.

      In July 1993, Taylor resigned as plant manager. R21-245.       Upon Taylor’s

resignation, Hansen assumed the running of the plant and served as plant manger

from July through September 1993. R19-24, 167; R20-354. Taylor subsequently

returned to the plant as a full time employee as a process or project engineer on the

condition that he not have to “assume managerial type duties.” R21-246. He

                                         12
remained involved in environmental issues, however, and in October 1993,

questioned the assistant production manager regarding the loss of mercury. R20-

325, 337-38.

      The Georgia Environmental Protection Division notified LCP in writing in

June 1993 that it proposed revoking the NPDES permit to discharge treated

wastewater in Purvis Creek based on “continuous violations . . . since May 1992 of

pH, total residual chlorine, and mercury.” Govt. Ex. 13-1d at 1. It explained that,

although it had provided LCP “Notice of Violation” letters twice in 1992 and had

requested that LCP “take all necessary measures to come into compliance,” “these

violations have continued” and “significant noncompliance” was documented in 10

out of 13 months from May 1992 through May 1993. Id. The notification

summarized that there had been “no progress . . . in upgrading the plant or its

operation” since the noncompliance had begun to be a serious problem. Id. at 2;

R20-274-276. Randall submitted formal written comments on the revocation

stating that “LCP has already taken steps to improve the situation by installing

additional filter capacity, repairing or replacing equipment and reducing the load

on the system” and referring to a 23 July plan addressing future corrective

measures. Govt. Ex. 10-6 at 4.

      In July and August 1993, Hansen directed the plant employees to begin

pumping the wastes into the large “bunker” tanks that had once been used to store

                                         13
oil although he knew that the wastewater mixed with oil could not be run through

the wastewater treatment system,. R20-48, 183, 328-29, 350. The plant

environmental/safety manager reported the use of the tanks to Randall in July.

Govt. Ex. 10-7x. After the EPD moved to revoke the plant’s permit, Hansen

advised the employees to “increase the flow on the wastewater treatment system to

a level that was to keep the water from running out the [cellroom] door” and into

the lake. R20-358-59. During their respective terms as plant manager, Hansen and

Taylor were advised of and observed “water [] flow[ing] out the back door of the

cellroom” as a result of a break in the cellroom berms, and “overflow[ing] on the

ground.” R20-327-28, 335-36, 341. The employees complained to Hansen,

Taylor, and Randall about “the water condition, the deterioration of the plant with

the pipes, the leaks, and the safety equipment,” and, despite assurances that

conditions would improve “[a]s soon as [the plant] g[o]t some money,” the plant

did not get “any money” and conditions did not change. R21-146-50.

       The NPDES permit was revoked on 23 September 1993. R20-275. LCP

            By letter, the bankruptcy creditors’ committee advised the state judge of the bankruptcy
proceedings and “the likely consequences that would result from any closing of the Brunswick
plant.” R9-228, Ex. B at 1. The committee represented that “even if actual production at [the plant]
was to cease, Hanlin would have an obligation to continue to spend considerable amounts of money
at [the] plant in order to avoid the possibility of an environmental catastrophe.” Id. at 2. A possible

       During this same period of time, Allied Signal and HoltraChem indicated

interest as buyers, and a financial agreement was worked out in which Allied

Signal would provide needed money, personnel, and raw materials or maintenance

parts for the plant, including an extra wastewater treatment facility. R9-228, Exs.

A & B; R19-149-51; R20-18, 80. As a part of the financial agreement, Allied

Signal loaned employee Mark White to LCP to serve as plant manager in October

1993.13 R19-152-53; R20-18. With the influx of Allied Signal’s resources,

conditions at the plant improved. R20-80. The purchase agreement eventually fell

through and shortly thereafter the facility closed. After the plant closed, Randall,

through the bankruptcy counsel, requested $1,500,000 in additional funds from the

bankruptcy court to deal with the environmental impact of closing but the request

was denied. R9-228, Ex. C at 2, 7, Feb. 8, 1994, letter from M. Patrick M.

      The government indicted Christian Hansen, Randall Hansen, Douglas Brent

Hanson, and Alfred R. Taylor for conspiracy to commit environmental crimes at the

site between 1 July 1985, and 1 February 1994, 18 U.S.C. § 371, (Count 1), and

various substantive crimes.14 R1-1-1. The charges included: violating the Clean

Water Act (“CWA”), 33 U.S.C. § 1319(c)(2)(A) and 18 U.S.C. § 2, by exceeding

the NPDES permit between June 1993 and January 1994 (Counts 2-21); violating

the Resource Conservation and Recovery Act (“RCRA”), 42 U.S.C. §§

6928(d)(2)(A) and (e), and 8 U.S.C. § 2, by storing wastewater on the cellroom

floor and permitting some to escape into the environment between 29 May 1993

and 1 February 1994 (Counts 22-32), storing wastewater in the Bunker “C” tanks

between 23 July 1993 and 1 February 1994 (Count 33), and knowingly endangering

employees by exposing them to impermissibly stored wastes and wastewaters

between 29 May 1993 and 1 February 1994 (Count 34); violating the

Comprehensive Environmental Response, Compensation, and Liability Act

unpermitted releases of chlorine or wastewater into the environment between 21

July and 23 October 1993 (Counts 35-41); and violating the Endangered Species

Act, 16 U.S.C. § 1538(a)(1)(B), 1538(g), and 1540(b)(1), by taking an endangered

species, a Wood Stork, as a result of discharging mercury into the marsh, Purvis

Creek, and the Turtle River (Count 42). R1-1. Hansen was charged with Counts 1-

42, Randall was charged with Counts 1-34 and 42, Hanson was charged with

Counts 1-6, 10-22, 24, 26-32, and 34-42, and Taylor was charged with Counts 1-32,

and 34-42. Id. Hanson, the former environmental and health and safety LCP

manager, pled guilty to a CERCLA offense (Count 41) and the offense under the

Endangered Species Act (Count 42) and testified against Hansen, Randall, and

Taylor.15 R3-83; R20-6. At the conclusion of the defendants’ case, the district

judge granted their motion for acquittal as to Count 42 but denied the motion as to

all other charges. R6-123. Hansen was convicted of all counts, Randall was

convicted of all charged counts, and Taylor was convicted of Counts 1-3, 10-11, 22-

26, 29-32, 34-35, and 38-41. R22-214-15. Their renewed motions for acquittal and

motions for judgment notwithstanding the verdict and/or for a new trial were

denied. R7-145, 146, 153-54, 163; R8-200.

assessment of $1,700, and two years of supervised release. R9-236. Taylor was

sentenced to 78 months of imprisonment, a special assessment of $1,000, and two

years of supervised release. R8-215. Each defendant appealed, and was allowed to

remain on bond pending appeal. R8-219, 221; R19-226, 238-40.

      On appeal, Hansen raises four issues: (1) the district court erred in admitting

the government’s expert witness testimony; (2) the district court’s instructions

misstated the reasonable doubt standard, improperly applied the concept of

reasonable corporate officer, improperly defined the elements of knowing

endangerment, and effectively eliminated the mens rea requirement from each

statutory violation; (3) the evidence was insufficient to support his convictions; and

(4) the district court erred in concluding that it lacked the authority to depart from

the applicable sentencing guidelines. Randall argues that: (1) district court erred

by not granting his motion for judgment of acquittal because the evidence was

insufficient to support his conviction for knowing endangerment under the RCRA

and the government never proved causation on counts 2-33; (2) the district court’s

instructions were erroneous on the elements of the charged substantive offenses and

on the responsible corporate officer instruction as an alternative basis for criminal

                                           18
liability; (3) the district court erroneously admitted high prejudicially and irrelevant

evidence; and (4) the district court erred by declining to depart downward. Taylor

maintains that the district court erred: (1) by not granting his motion for judgment

of acquittal and for a new trial based on insufficiency of the evidence; (2) in its

instruction concerning the wastewater treatment system; and (3) in sentencing him.



                                         II. DISCUSSION

A. Admission of Expert Witness Testimony

        Hansen argues that the district court erred in admitting testimony from

government expert witness Daniel Teitelbaum because the government failed to

disclose Teitelbaum’s checkered history of credibility and the court failed to

conduct a hearing regarding the testimony. Hansen also maintains that the district

court erred in admitting the testimony of Teitelbaum and government expert witness

Christopher Reh because the testimony was unreliable, irrelevant, and highly

prejudicial. The government responds that Hansen waived the arguments regarding

Teitelbaum’s testimony by failing to object to the testimony at trial.

        The week before trial, Hansen moved for a Daubert16 hearing and to exclude


        16
           Daubert v. Merrell Dow Pharm., Inc., 509 U.S. 579, 113 S. Ct. 2786 (1993). In Daubert,
the Court held that, when “[f]aced with a proffer of expert scientific testimony, . . . the trial judge
must determine . . . whether the expert is proposing to testify to (1) scientific knowledge that (2) will
assist the trier of fact to understand or determine a fact in issue.” Id. at 592, 113 S. Ct. at 2796.


                                                   19
the testimony of expert witnesses regarding certain allegedly scientific conclusions

and exhibits. R4-94-95; R6-110-1. Noting that the motion was directed to the

expert testimony regarding the effect of high mercury levels on endangered species

as charged in Count 42, the district court denied it, finding that the motion did “not

identif[y] the source, the substance, or most importantly the underlying

methodology of this testimony” and that, therefore, there was “no underlying

methodology or reasoning for the court to assess.” R6-110-1-2, 4.

       During the trial, Teitelbaum confirmed that he had previously testified as an

expert witness, and explained that “it has been a regular portion of [his] practice

over the years.”17 R20-230-31. Hansen neither objected nor examined Teitelbaum

after the government moved to tender Teitelbaum as an expert, and the court

directed that the jury consider him an expert in his field. Id. at 232.

       Teitelbaum testified regarding the plant employees’ potential exposure to

hazardous substances. Based on his review of “the large number of biological

samples,” “many interviews,” the “documents concerning the health and hygiene

program,” and other documents, he found “a substantial amount of spillage of

sodium hydroxide,” “numerous chlorine leaks,” and spills and leaks of hydrochloric


       17
          On cross-examination, Teitelbaum stated that this was the first time that he had testified
as “a consultant for the U.S. Attorney,” but explained that he had testified “for OSHA many times,”
“for the Department of Justice a number of times,” and for “the EPA.” R20-255-56. He was asked
whether he considered the government to be a “pretty good customer” for his services, and
responded that he did not “take any money from the government” for consulting services. Id. at 256.

                                                 20
acid at the plant. R20-233-35; see also 248-49. He noted that, because the sodium

hydroxide spillage had a very high pH and was quite caustic, contact with the

spillage could cause a first- to third-degree burn, or even be lethal. Id. at 233-34.

Teitelbaum explained that exposure to the chlorine leaks could cause “severe

injuries to eyes, upper airways, and lungs, and, under some circumstances, death.”

Id. at 234. He commented that hydrochloric acid was a “classic poison” which

would also cause burns and potential death. Id. at 234-35. Based on the biological

samples, he concluded that the employees were “in danger of death or serious

bodily injury.” Id. at 244-45, 248. Finally, Teitelbaum noted that the data showed

the mercury levels in the workers’ urine were “between two and five times the

acceptable level of excretion, based on the World Health Organization or the

NIOSH recommendations.” Id. at 244-45. No objections were raised to his

testimony. Id. at 232-63.

      At sentencing, the probation officer noted that he had “discredit[ed]” one of

Hansen’s witnesses “because he was not even at the LCP Plant” and “did not have

firsthand knowledge to see this.” R13-26. Hansen’s attorney responded that,

based on the probation officer’s theory, Teitelbaum’s testimony should also be

discounted “because he never went to the plant before it was shut down.” Id. at 28.

The district judge commented that Teitelbaum “made a very credible witness. I

think the best witness that the Government had.” Id. at 29.

                                           21
      We review for abuse of discretion both the district court’s decisions

regarding the admission of expert testimony and reliability of an expert, Kuhmo

Tire Co., Ltd. v. Carmichael, 526 U.S. 137, 152, 119 S. Ct. 1167, 1176 (1989), and

the denial of a Daubert hearing, United States v. Nichols, 169 F.3d 1255, 1263

(10th Cir. 1999). “Absent an objection, we can review the challenged evidence

only for plain error.” Christopher v. Cutter Labs., 53 F.3d 1184, 1192 (11th Cir.

1995).

      Scientific expert testimony is admissible if “(1) the expert is qualified to

testify competently regarding the matters he intends to address; (2) the methodology

by which the expert reaches his conclusions is sufficiently reliable as determined by

the sort of inquiry mandated in Daubert; and (3) the testimony assists the trier of

fact, through the application of scientific, technical, or specialized expertise, to

understand the evidence or to determine a fact in issue.” City of Tuscaloosa v.

Harcros Chems., Inc., 158 F.3d 548, 562 (11th Cir. 1998). In Daubert, the Supreme

Court suggested a flexible inquiry regarding the methodology considering such

factors as “whether it can be (and has been) tested,” whether it “has been subjected

to peer review and publication,” the known or potential rate of error,” “ the

existence and maintenance of standards controlling the technique’s operation, and

the degree it is accepted as reliable within the relevant scientific community.” 509

U.S. at 591, 593-94, 113 S. Ct. at 2795-96. Daubert hearings are not required, but

                                           22
may be helpful in “complicated cases involving multiple expert witnesses.” City of

Tuscaloosa, 158 F.3d at 564-65 n. 21. A district court should conduct a Daubert

inquiry when the opposing party’s motion for a hearing is supported by “conflicting

medical literature and expert testimony.” Tanner v. Westbrook, 174 F.3d 542, 546

(5th Cir. 1999). Consistent with Daubert, the evidence must be scientifically related

to the disputed facts at issue in the case. Allison v. McGhan Med. Corp., 184 F. 3d

1300, 1312 (11th Cir. 1999).

       Hansen’s motion for a Daubert hearing was neither addressed to the charges

to which Teitelbaum testified, or his testimony in general, nor supported by the

source, substance, or methodology of the challenged testimony. Hansen failed to

object to either Teitelbaum’s qualification as an expert or his testimony during trial.

Teitelbaum’s testimony was based on his review of biological samples, interviews,

and documents, and assisted the trier of fact in understanding the potential injuries

that could result from the conditions at the plant. The district judge did not abuse

his discretion by denying the motion or by admitting the testimony.

       To the extent that Hansen raises a Brady18 claim that the government

suppressed exculpatory or impeachment evidence by failing to disclose



       18
          Brady v. Maryland, 373 U.S. 83, 87, 83 S. Ct. 1194, 1196-97 (1963) (“The suppression
by the prosecution of evidence favorable to the accused upon request violates due process where the
evidence is material to guilt or to punishment, irrespective of the good faith or bad faith of the
prosecution.”).

                                                23
Teitelbaum’s “checkered” past, we find that it is without basis. In order to state

such a claim, a defendant must show (1) “that the government possessed evidence

favorable to the defendant (including impeachment evidence) . . .; (2) that the

defendant does not possess the evidence nor could he obtain it himself with any

reasonable diligence . . . ; (3) that the prosecution suppressed the favorable evidence

. . . ; and (4) that had the evidence been disclosed to the defense, a reasonable

probability exists that the outcome of the proceedings would have been different.”

United States v. Meros, 866 F.2d 1304, 1308 (11th Cir. 1989) (per curiam). In this

case, the evidence which Hansen alleges the government failed to disclose consists

of court opinions either disregarding or discrediting Teitelbaum’s testimony.

Although Hansen argues that the government knew of this discredited testimony

based on Teitelbaum’s previous testimony for the government, Hansen fails to show

that the government was in actual possession of the information or actually

suppressed it. Further, the information was available to Hansen through reasonable

diligence both before and during the trial.19 The cases were all available through

       19
           Hansen argues that Teitelbaum’s testimony was “discredited” in four cases: General
Electric Co. v. Joiner, 522 U.S. 136, 118 S. Ct. 512 (1997), Sweger v. Texaco, Inc., Nos. 88-1781,
88-1834 and 88-2745 (10th Cir. Feb. 22, 1991); Land v. United States, 35 Fed. Cl. 345 (1996), and
National Bank of Commerce v. Associated Milk Producers, Inc., 22 F. Supp. 2d 942 (E.D. Ark.
1998). In General Elec. Co., the Court found that the district court did not abuse its discretion in
excluding the testimony of Teitelbaum (and other expert witnesses) because the studies on which
he relied were not sufficient to support his conclusion. 522 U.S. at 146-47, 118 S. Ct. at 519. In
Sweger, the court found that Teitelbaum’s testimony did not provide the necessary certainty to
establish causation. Sweger, slip op. at 1, 5-6. In Land, Teitelbaum appeared as the plaintiffs’
medical expert. 35 Fed. Cl. at 352 n. 7. The hearing officer found Teitelbuam’s “‘preliminary’

                                                 24
legal research and information on them could have been, but was not, addressed

during Teitelbaum’s testimony. Finally, the cases relied on by Hansen all relate to

Teitelbaum’s testimony in tort actions as to causation of a specific injury. They do

not, therefore, have probative value as to his testimony regarding potential health

effects of the chemicals or the employees’ risk of death or serious injury after

exposure to these chemicals. Hansen is unable to show a reasonable probability that

the information would have changed the outcome of the proceedings.

       Christopher Reh, an employee of the National Institute for Occupational

Safety and Health (“NIOSH”), also testified for the government. R20-192. The

district judge qualified him as an expert in the field of industrial hygiene.20 Id. at

194. Reh explained that he was assigned to the Brunswick plant as the project

officer after NIOSH received “a valid request for a health hazard evaluation” from

one of the plant’s unions in 1987.21 Id. at 196. He said that, during the initial site

visit, he and his team met with Taylor, a plant engineer, and a few union




medical opinion” regarding the cause of the plaintiffs’ injuries to be “of little value because Dr.
Teitelbaum did not conduct physical examinations of the plaintiffs.” Id. In National Bank of
Commerce, the court found that Teitelbaum’s view of the causation of the plaintiff’s cancer was
“undercut by the inadequacy of . . . reliable scientific proof of causation.” 22 F.Supp. at 967.
       20
          Neither Hansen nor his codefendants questioned Reh regarding his background or his area
of expertise and raised no objections to Reh’s qualification. R20-194.
       21
          Reh indicated that they were requested to evaluate the health hazards associated with
mercury, chlorine, and hydrochloric acid. R20-199, 203; Govt. Ex. 40-1b.

                                                25
representatives to discuss the request.22 Id. at 196-98. They visited the plant, and

observed “mercury in many places on the cellroom floor in cracks or crevices,” and

passively monitored mercury exposure in the workers’ “breathing zone.” Id. at

198-99. They found that the plant was not using the creatnine monitoring scale, but

were reporting mercury levels by “micrograms per liter.” Id. at 204. The monitors

found that mercury exposure exceeded the NIOSH and OSHA recommended

levels.23 Taylor’s objection to further testimony from Reh on the grounds of

relevance was overruled. Id. at 201. Reh and his team advised Taylor of their

findings by letter and recommended use of creatnine correction urine mercury

monitoring which would indicate the amount of mercury per gram of creatnine. Id.

at 201-03; Govt. Ex. 40-1b. From the results of the first visit, the team made a

second visit to conduct a more in-depth study in 1988. R20-202. During the

second visit, the team used an active sampling method to determine 28 workers’

breathing zone exposure levels, collected urine samples from 58 workers, and

administered questionnaires to and conducted physical examinations of 65 workers.

Id. at 205-07. Taylor was provided with a written interim report in 1988 and a final

       22
            The NIOSH team consisted of Reh, a medical doctor, and another industrial hygienist.
R20-198.
       23
           Reh explained that the NIOSH recommended exposure levels (“REL”) were 50
micrograms of mercury per cubic meter of air and that the OSHA permissible exposure levels
(“PEL”) are 100 micrograms of mercury per cubic meter of air. R20-200. He said that all of the
sixteen monitored workers showed RELs above 50, and eleven of the monitored workers had levels
above the PEL. Id. at 200-01.

                                                26
report in 1991, both of which showed that workers had mercury levels above

recommended standards.24 Id. at 207-08, 210, 214; Govt. Exs. 40-1c and 1d.

       The government offered Reh’s testimony to show that the workers were

placed “in imminent danger of death or serious bodily injury” and that Hansen,

Randall, and Taylor were aware of the workers’ exposure to hazardous substances.

This testimony supports both of those propositions. The district court did not abuse

its discretion by admitting the testimony of Reh.

B. Insufficiency of the Evidence

       We review the denial of a motion for a new trial for abuse of discretion, and

the denial of a motion for judgment of acquittal de novo. United States v. Pistone,

177 F.3d 957, 958 (11th Cir. 1999) (per curiam). To uphold the denial of a motion

for judgment of acquittal, we “need only determine that a reasonable fact-finder

could conclude that the evidence established the defendant’s guilt beyond a

reasonable doubt.” Id. When considering the sufficiency of the evidence, we

“view the facts and draw all reasonable inferences therefrom in the light most

favorable to the government.” United States v. Slocum, 708 F.2d 587, 594 (11th

Cir. 1983).



       24
          Reh reported that they found that 29 of the tested 58 workers had urine mercury levels
which exceeded the World Health Organization recommended standard of 50. R20-208, 210. The
average level was 136 micrograms per gram of creatinine, with a range from 2 to 689. Id. at 210.


                                               27
         1. Position of authority

         “To prove aiding and abetting, the government must demonstrate that a

substantive offense was committed, that the defendant associated himself with the

criminal venture, and that he committed some act which furthered the crime.”

United States v. Hamblin, 911 F.2d 551, 557 (11th Cir. 1990). “[T]he government

must show that the defendant shared the same unlawful intent as the actual

perpetrator” but does not need to prove that “the defendant was present at the scene

when the crime occurred, or that he was an active participant.” Id. at 557-58;

United States v. Pepe, 747 F.2d 632, 665 (11th Cir. 1984) (“aider and abettor . . .

need not even be present”). “Encouraging” a violation and “discouraging” the

reporting of the violation, United States v. Sinskey, 119 F.3d 712, 718 (8th Cir.

1997), and “personally attempting to avoid [a violation’s] detection by the [RCRA]

inspectors,” United States v. Self, 2 F.3d 1071, 1089 (10th Cir. 1993), have been

held sufficient to show that a defendant aided and abetted the commission of a

crime.

         The indictment alleged that the defendants, “after learning that the Brunswick

facility was disposing of hazardous wastes . . . without a RCRA permit, continued

to operate the Brunswick facility in such a manner as to continue the disposal of

these hazardous wastes without expending adequate funds . . . to prevent the

disposal of such hazardous wastes into the environment.” R1-1-11. The jury was

                                           28
instructed that the defendants were responsible for the acts of others that they

“wilfully directed,” “authorized,” or aided and abetted by “willfully joining together

with [another] person in the commission of a crime.” R22-181. The district court

denied Taylor’s motion to acquit or for a new trial on these charges finding that “the

Defendants worked for LCP in positions of responsibility and authority while . . .

the violations took place.” R8-200-23.

               a. Hansen

      Hansen maintains that the evidence failed to show that he was in a position of

authority after he was deposed as CEO in April 1993 until he began serving as plant

manager on 16 July 1993, and not after he was officially replaced as plant manager

by Allied employee Mark White on 18 October 1993. Therefore, he contends that

the district court erred in not granting his motion for judgment of acquittal as to the

18 counts that occurred after 18 October 1993 (Counts 6-9, 14-15, 19-21, 23, 25,

29, 30-32, 38-40), the two counts that occurred between April and July 1993

(Counts 2 and 10), and the count that arose on 22 October 1993 (Count 33).

      The testimony at trial indicated that Hansen was aware that wastewater was

permitted to flow out the cellroom back door in June 1993,25 and directed the use of

the old Bunker C storage tanks for storage of wastewater, including the

inadequately treated wastewater from the treatment system, from July through

September 1993.26 Although the acts continued after Hansen left his decision-

making position, the acts occurred at his direction. This evidence was sufficient for

the jury to reasonably conclude beyond a reasonable doubt that his acts were in

furtherance of the violations. The district court did not err in denying Hansen’s

motion for judgment of acquittal or motion for new trial.

              b. Randall

       Randall claims that the government presented no evidence that he personally

treated, stored, or disposed of a hazardous waste, personally effected a CWA

violation, or instructed an agent to do so. He maintains that, under the laws of

bankruptcy and corporate governance, he lacked the authority to close the plant or

to allocate the funds for the needed capital improvements. He contends that LCP

needed the bankruptcy court’s approval to use the bankruptcy estate’s assets, or to

obtain a new debt, to perform the needed repairs at the Brunswick plant.

       In February 1994, LCP applied to the bankruptcy court for the funds “to

shutdown” the plant and for new equipment, but the motion was denied. Def.

          Testimony of former LCP health and safety manager Douglas Brent Hanson, R20-48-49,
LCP maintenance handler and expeditor George Mower, R20-183, and LCP former production
manager Duane Outhwaite, R20-350. Outhwaite testified that the storage tanks were used for
wastewater overflow to keep the inadequately treated wastewater from “running out the door” and
to help prevent the deep pools of wastewater from forming on the cellroom floors. R20-350, 358.


                                              30
Hanlin Board of Directors member James Mathis testified that Randall was

responsible for “run[ning] the day-to-day operations of the company” once he

became the interim CEO and COO. R19-160. He said that the Board was “very

interested in whether the environmental problems–whether we were in a position of

compliance with the environmental regulations. But the information that we had

indicated that, really, compliance was not a problem.” Id. at 164. He explained

that, as a result of the weekly reports on the plant’s operations, the Board believed

that “there were really no excursions of any significance going on”. Id. at 165.27

Mathis said that Randall “had the primary responsibility” for providing information

regarding the environmental compliance issues to the Board and that Hansen fed

“information to Randall in that regard.” Id. at 166. He agreed that the decision to

sell the plant would have been a board decision requiring the approval of the

bankruptcy court. Id. at 174-75.

       LCP, as a debtor in possession, could “use the property of the estate in the

ordinary course of business,” but needed court approval to “use, sell, or lease, other

than in the ordinary course of business, property of the estate.” 11 U.S.C. §

363(c)(1) and (b)(1). It could obtain unsecured credit . . . in the ordinary course of

business,” but needed court approval “to obtain unsecured credit or to incur

       27
           Mathis testified that there were places on the report forms for the “number of excursions”
or environmental noncompliances which “were filled in with ‘zeros’ each time.” R19-165. He said
that they later learned that the zeros were clerical errors. Id.

                                                 31
unsecured debt other than” “in the ordinary course of business.” Id. at 364(a) and

(b). Bankruptcy does not insulate a debtor from environmental regulatory statutes.

In reviewing an injunction to clean up a hazardous waste site, the Supreme Court

commented:

      [W]e do not suggest that [the debtor’s] discharge [in bankruptcy] will
      shield him from prosecution for having violated the environmental
      laws . . . or for criminal contempt for not performing his obligations
      under the injunction prior to bankruptcy. . . . [W]e do not hold that the
      injunction . . . against any conduct that will contribute to the pollution
      of the site or the State’s wasters is dischargeable in bankruptcy . . .
      Finally, we do not question that anyone in possession of the site . . .
      must comply with the environmental laws . . . . Plainly, that person or
      firm may not maintain a nuisance, pollute the waters of the State, or
      refuse to remove the source of such conditions.

Ohio v. Kovacs, 469 U.S. 274, 284-85, 105 S. Ct. 705, 710-11 (1985). See also

Midatlantic Nat’l Bank v. New Jersey Dept. of Envtl. Protection, 474 U.S. 494, 407,

106 S. Ct. 755, 762 (1985) (A bankrupt debtor in possession “may not abandon

property in contravention of a . . . regulation that is reasonably designed to protect

the public health or safety from identified hazards.”).

      Although Randall claims that his role as Executive Vice-President and acting

CEO was limited to financial matters, he also received daily reports about the

plant’s operations and environmental problems, R16-97-98, R21, 359, wrote and

received memos regarding specific plant operational problems, Govt. Ex. 104, 1-6f,

1-8a, 1-12, received monthly written environmental reports, Govt. Ex. 10-1o-10-

1nn, 10-7c-7d, 10-7f, and oral environmental reports, R21-64, 359. He admitted

that Hanlin’s bankruptcy was not an excuse for violating environmental laws. R21-

219-21. There is no indication that he asked the Hanlin Board or the bankruptcy

court to close the plant. The evidence indicates that he apparently misled them into

believing that environmental compliance was not a problem. After the Georgia

EPD attempted to revoke the plant’s NPDES permit in June 1993, Randall

contested the revocation, explaining that the plant’s CWA violations were due to a

lightning strike and equipment failures, and asserted that “LCP has already taken

steps to improve the situation.” Govt. Ex. 10-6. This evidence was sufficient for

the jury to conclude that Randall actions were in furtherance of the violations.



             c. Taylor

      Taylor argues that he should not be held responsible for the environmental

violations that occurred after he resigned as plant manager, specifically counts 2-3,

25, 29-32, 38-41. Taylor resigned as plant manager on 16 July 1993, R21-245, but

returned shortly thereafter as a project engineer and continued in that position until

the plant closed, R21-246-47, 317-18. As project engineer, Taylor was directly

involved in responding to the plant’s environmental and safety problems and, at

Hansen’s request, developed a list of short-term solutions to the problems with

estimated costs. R20-338; R21-247-48. Taylor’s proposed solutions were

                                          33
subsequently funded. R21-247-48.

       Although Taylor left his managerial position, he continued to work in a

position in which he directed or authorized acts of the employees on environmental

and safety problems.28 Testimony at trial indicated that, in October 1993, Taylor

was aware of the wastewater overflow from the cellrooms, the excess loss of

mercury, and the use of the tank cars for wastewater storage, and that he supervised

the release of the overflow.29 This evidence was sufficient for the jury to conclude

beyond a reasonable doubt that these acts were in furtherance of the violations. The

district court did not err in denying his motion for a new trial.

       2. Hazardous substances or materials


       28
          Despite Taylor’s resignation as plant manager and his re-employment as project engineer,
he was considered to be in a management position. See R20-152 (D. Brent Hanson testified that
Taylor was his immediate supervisor both before and after his resignation and re-employment); id
at 335 (Dunn testified that Taylor “probably would have been plant manager” in late 1993), 337
(Dunn said that in “October of ‘93 I would assume [Taylor] was plant manager.”); id. at 312, Govt
Ex. 13-4 (19 January 1994 letter from Georgia EPD acting unit coordinator Susan Eason to “Plant
Manager” Taylor in which she referenced Taylor’s explanation for “NPDES excursions” at a 6
December 1993 meeting). But see Govt. Exs. 13-2ff, gg, hh, ii, and jj (letters from Mark S. White,
as “Plant Manager,” to EPD dated October-February 1994).
       29
           Testimony of James Dunn. R20-335-39. Taylor directed a memorandum addressing the
mercury losses and suggesting a solution to LCP employee Chris Dunn on 4 October 1993. Govt.
Ex. 19-5. Dunn responded “yes” when asked whether Taylor was aware of the overflow release
from the backdoor of the cellroom. R20-327-28. Dunn testified that Taylor observed the overflow
“on the ground.” Id. at 336. Dunn said that he told Taylor he was having trouble pumping the
waste into the tank cars and that mercury loss was due to “leaks coming out of the products or it was
tied up in hazardous waste muds.” R20-337, 339. By memorandum, Taylor proposed a flow plan
for the projected waste streams of “19 to 125 gallons per minute” when the wastewater treatment
system was only working at a 40 gallon per minute capacity. Id. at 340; Govt Ex. 19-4a. Wilbur
Outhwaite testified that Taylor advised that the employees needed to empty the wastewater from
the tank cars. R20-356.

                                                 34
      Taylor and Hansen argue that the government failed to prove that the

untreated wastewater contained enough mercury and caustic to meet the

environmental laws’ definition of hazardous substances or materials, or that the

untreated wastewater was improperly stored.

             a. Hazardous substances as defined

      OSHA chemist Clinton Leroy Merrell testified that samples which were

submitted from LCP on 9 September 1992 tested as containing 8 to 30 parts per

million of mercury, and six to ten-percent caustic, with a pH of 14. R21-163, 165-

67; Govt Exs. 45-6, 45-9. Former LCP plant manager Hugh Leroy Croom testified

that, in January 1993, the untreated wastewater may have had “a high pH, and . . .

some mercury,” but would not have contained mercury sludge. R16-91, 131-32. He

said that the pH could be high enough to be a danger “at times” but that it did not

stay high and varied according to the spills. Id. at 132; R19-35-36. However, he

testified that muds containing mercury and caustic were washed onto the cellroom

floors every three or four days when the treatment system’s filters were back

washed. R16-127-28; R19-103. When asked whether the wastewater on the

cellroom floors would be considered a hazardous waste, Croom responded “[m]ost

of the time, probably it was.” R16-112-13; see also id. at 128 (Croom admitted that

wastes on the cellroom floor were listed as hazardous wastes).

      Dr. Teitelbaum testified that a fall and submersion into caustic soda with a pH

                                          35
of 14 would cause a third-degree burn over the entire body with a likelihood of

death. R20-241-42. LCP former employee Duane Carver testified that, some time

between 1987 and 1993, he stepped into the cellroom sump hole and went in up to

his waist. R19-226-28. He knew that the pH was “pretty high” because he quickly

felt it. Id. at 228. He showered and was able to get most of it off so that he “didn’t

get burned all the way” and did not seek medical attention. Id. at 229-30, 251.

      Environmental Protection Agency regulatory expert Paul Peronaud explained

the hazardous waste classifications to the jury, R21-11-13, and the jury was

instructed as to various types of hazardous wastes, R22-199-200. 30

      The Waste Water Treatment Operators Logs for the periods of the indictment


      30
         Specifically, the jury was instructed:
               [T]he following wastes are listed as hazardous wastes under the Resource
      Conservation and Recovery Act, that is, RCRA:
               K-106 is wastewater treatment sludge from the mercury cell process in
      chlorine production.
               K-071 is brine purification muds from the mercury cell process in chlorine
      production, where separately prepurified brine is not used.
               And U-151 is simply mercury.
               Now you are instructed that a solid waste exhibits the characteristic of
      toxicity for mercury if, using the test methods set forth in the regulations, a
      representative sample of the waste contains mercury at a concentration of equal to
      or greater than 0.2 milligrams per liter.
               Under the law, liquid wastes which are “corrosive” are identified as
      hazardous wastes. A liquid waste is considered to be corrosive if a representative
      sample of the waste is aqueous and has a pH less than or equal to 2 or greater than
      or equal to 12.5.
               I instruct you that when a hazardous waste listed under the regulations is
      mixed with a solid waste, the resulting mixture is a hazardous waste if the reason for
      the listing of the hazardous waste is that it is a toxic waste.

R22-199-200.

                                                36
showed that the wastewater often contained more than 200 parts per billion of

mercury.31 Govt. Exs. 4, 5, 6-1. Former LCP employee Dunn testified that Taylor

directed the employees to “put a sign up” labeling the wastewater in the rail cars as

“[h]azardous waste materials.” R20-345. Taylor testified that the pH of the plant’s

wastewater was normally between seven and ten, and in concentration of eight to ten

percent. R21-262, 264.

       A “hazardous waste” is defined as

       a solid waste, or combination of solid wastes, which because of its
       quantity, concentration, or physical, chemical, or infectious
       characteristics may–
                     (A) cause, or significantly contribute to an increase in
              mortality or an increase in serious irreversible, or incapacitating
              reversible, illness; or
                     (B) pose a substantial present or potential hazard to
              human health or the environment when improperly treated,
              stored, transported, or disposed of, or otherwise managed.

42 U.S.C. § 6903(5). Hazardous wastes are categorized as either “listed” hazardous

substances or “characteristic” hazardous substances. 40 C.F.R. § 261.3(a); R21-11-

15. The “characteristic” hazardous substances are not per se hazardous but may be


       31
          LCP former employee Carver explained that the line for “Discharge HC (ppb)” showed
“the mercury level in the discharge water coming from the wastewater system.” R19-209. The
logs provided for thirteen readings per day, but readings were typically taken only twelve times per
day. Mercury levels were recorded as above 200 for nine readings on 17 April, six readings on 28
June, eight readings on 28 August, four readings on 29 August, three readings on 12 September, four
readings on 6 October, two readings on 9 October, three readings on 13 October, nine readings on
18 October, six readings on October 22, and nine readings on 5 November, 1993. Govt. Exs. 4, 5,
6-1. The logs show that the system was not working during readings on 17 April, 21 June, 27-28
June, 29 August, 12 September, 6-9 October, 12-13 October, and 18-21 October 1993. Id.

                                                 37
classified as hazardous if, because of a mixture with a hazardous substance, testing

proves that the substance exhibits characteristics of hazardous waste. 40 C.F.R. §§

261.3(a)(2)(i) and 261.20(a). Characteristics of hazardous waste include ignitability,

corrosivity, reactivity, and toxicity. 40 C.F.R. §§ 261.21, 261.22, 261.23, and

261.24. Wastewater containing mercury is classified as a characteristic hazardous

substance when the water contains 200 parts per billion or more of mercury. Id. at §

261.24 (a), Table. “Wastewater treatment sludge from the mercury cell process in

chlorine production” is listed as hazardous waste K106. Id. at § 261.32. Wastewater

containing caustic is classified as a characteristic hazardous substance when the

water “has a pH less than or equal to 2 or greater than or equal to 12.5.” Id. at §

261.22(a)(1). Once solid wastes are mixed with sludge or caustic, they are defined

as hazardous. Id. at § 261.3(a)(2)(iv).

      Where there is no sampling of the actual wastes, the government may prove

the hazardous nature of the material by inventories, hazardous waste logs, internal

memoranda, and trial testimony. United States v. Baytank (Houston), Inc., 934 F.2d

599, 614 (5th Cir. 1991). The government is not required to prove that material is

hazardous by EPA testing. United States v. Self, 2 F.3d 1071, 1086 (10th Cir. 1993).

We find that the testimony of the former LCP employees and the wastewater logs

were sufficient for the jury to find that the untreated wastewater contained enough

mercury and caustic to meet the environmental laws’ definition of hazardous

                                           38
substances or materials.

             b. Storage of hazardous materials.

      Taylor and Hansen maintain that the accumulation of wastewater on the

cellroom floors did not violate federal law because the wastewaters were not stored

there for the statutory requisite of 90 days. Croom testified that hazardous

wastewater was on the cellroom floors “[a]t times,” R16-114, and that hazardous

materials were shipped, turned over, or treated within 90 days, R19-41. In response

to a question as to whether wastewater on the cellroom floors was a regular

occurrence in 1992, he responded that it was in both cellrooms in 1992, but when he

left “it was just mostly in #2.” R16-114. Former LCP employee Roger Cooper

testified that on 28 June 1993, although wastewater was pumped to the railcars for

storage from cellroom two, the cellroom one floor was dry. R19-275-76, 281-82;

Govt. Ex. 6-1. He explained that they “tried to keep [the wastewater in cellroom

one] pumped over to #2 cellroom” because of the possibility that water would escape

from cellroom one as a result of cracks in its floor. R19-284-85. Dirt dikes were

constructed in the cellrooms to prevent the wastewater from leaking, but the dikes

were frequently breached. R19-256; R25-26. The cellrooms were often “full of

water” so that the employees had to wade into standing wastewater to repair the

pumps. R20-318; R19-205.

      Hazardous waste generators are permitted to “accumulate hazardous waste on-

                                          39
site for 90 days or less without a permit” if “the waste is placed” in tanks visibly

marked with “[t]he date upon which each period of accumulation begins” and clearly

labeled as “Hazardous Waste.” 40 C.F.R. § 262.34(a)(1)(ii), (2), and (3). A “tank”

is “a stationary device, designed to contain an accumulation of hazardous waste

which is constructed primarily of non-earthen materials . . . which provide structural

support.” 40 C.F.R. § 260.10.

      There was no evidence that suggested that the cellrooms, in which earthen

berms were constructed to contain the wastewater, were marked with the date of

accumulation or labeled as containing hazardous wastes and thus qualified as

“tanks.” The testimony and logs indicate that the wastewater, which may have

abated in cellroom one during various periods of time, remained in cellroom two and

was present for more than 90 days. Therefore, the evidence was sufficient for the

jury to find that the wastewater was improperly stored.

      3. Knowing Endangerment Under RCRA

             Hansen, Randall, and Taylor argue that the evidence was insufficient to

convict them for knowing endangerment. They acknowledge that the government

may have shown that they “could have been aware” of the inherent dangers of

working in a chlor-alkali plant, but argue that it failed to show that they knew and

had an actual belief that the conduct which allegedly violated the environmental laws

was substantially certain to cause death or serious bodily injury to others.

                                           40
Specifically, they maintain that, while the evidence showed that the employees were

exposed to mercury, the evidence did not show that they were endangered due to any

RCRA violation. They contend that the evidence of the employees’ exposure to

caustic was not sufficient to support the conviction for knowing endangerment.

They claim that the government did not show that they had actual knowledge that

their conduct in causing the RCRA violation was at that time substantially certain to

place the employees in imminent danger of death or serious bodily injury. They also

posit that there was no evidence that they were participants in any alleged

conspiracy.

      For a conviction of knowing endangerment under the RCRA, the government

must prove that the defendants knowingly caused the illegal treatment, storage, or

disposal of hazardous wastes while knowing that such conduct placed others in

imminent danger of death or serious injury. 42 U.S.C. § 6928(e). A defendant acts

“knowingly” “if he is aware or believes that his conduct is substantially certain to

cause danger of death or serious bodily injury.” Id. at 6928(f)(1)(C). The

defendant must have possessed “actual awareness or actual belief.” Id. at

6928(f)(2)(A). Circumstantial evidence, “including evidence that the defendant took

affirmative steps to shield himself from relevant information,” may be used to prove

the defendant’s awareness or belief. Id. The knowing endangerment statute was

drafted to “assure to the extent possible that persons are not prosecuted or convicted

                                          41
unjustly for making difficult business judgments where such judgments are made

without the necessary scienter” “however dire may be the danger in fact created.” S.

Rep. 96-172, at 37-38 (1979), reprinted in 1980 U.S.C.C.A.N. 5019, 5036-38. The

penalties imposed by the knowing endangerment section were “designed for the

occasional case where the defendant’s knowing conduct shows that his respect for

human life is utterly lacking and it is merely fortuitous that his conduct may not have

caused a disaster.” Id. at 38, 1980 U.S.C.C.A.N. at 5038. We have held that “[t]he

government need only prove that a defendant had knowledge of the general

hazardous character of the chemical” and knew “that the chemicals have the

potential to be harmful to others or to the environment.” United States v. Goldsmith,

978 F.2d 643, 645-646 (11th Cir. 1992) (per curiam) (internal quotations and citation

omitted). “[W]hile knowledge of prior illegal activity is not conclusive as to

whether a defendant possessed the requisite knowledge of later illegal activity, it

most certainly provides circumstantial evidence of the defendant’s later knowledge

from which the jury may draw the necessary inference.” Self, 2 F.3d at 1088.

      The statute defines “serious bodily injury” as “(A) bodily injury which

involves a substantial risk of death; (B) unconsciousness; (C) extreme physical pain;

(D) protracted and obvious disfigurement; or (E) protracted loss or impairment of

the function of a bodily member, organ, or mental faculty.” 42 U.S.C. § 6928(f)(6).

A condition which may cause one of the statutorily defined conditions is sufficient

                                          42
to show “serious bodily injury.” See United States v. Protex Industries, Inc., 874

F.2d 740, 743 (10th Cir. 1989) (finding that a serious bodily injury was suffered by

employees who contracted psychoorganic syndrome which may cause a mental

faculties impairment).

                       a. The Evidence of Endangerment

       Former LCP employees testified that they suffered serious skin and

respiratory conditions from the wastewater on the cellroom floors.32 A November

1992 memorandum from Taylor to Randall showed Taylor’s concern for needed

repairs “to avert severe safety and environmental problems.” Govt. Ex. 1-5. The

urinalysis testing on employees showed “an increase” in the number with mercury

levels which exceeded the 150 action level from 1986 to 1993. R21-294-96. Taylor

admitted that most of the employees in the cellroom were removed to other plant

locations “before any medical condition occurred” but said that he did not see any

“reason to draw any correlation between” the rise in the number of employees



       32
           Hugh Croom explained that “when the pH was high [in the wastewater on the cellroom
floors] and somebody stepped over in it, it could easily burn their skin on their legs.” R16-121. He
volunteered that caustic could “peel the skin off” a person if he or she fell into it. R19-107. He said
that airborne mercury could cause problems because of the potential for accumulation in the body.
Id. at 108. Duane Carver testified that he received second- and third-degree burns on his thighs,
R19-182, 197, and that he and other employees shoveled mercury off the cellroom floors, R19-192.
He explained that there was “plenty” of mercury to see “under the mud and also beaded up on top
in the mud.” Id. He said that “[t]here would be so much [mercury] that it would be running off of
the mud” and that “[y]ou could get a shovelful and lean your shovel over, and the mercury would
just run off the shovel onto the floor.” Id. at 192-93. John Baker testified that the wastewater
“would cause severe burns.” Id. at 245.

exposed to excess mercury and the dumping of hazardous wastes and mercury. Id.

at 294, 296.33

       Expert testimony and reports linked exposure to mercury and caustic to a

variety of serious health problems. The National Institute for Occupational Safety

and Health (NIOSH) report on sodium hydroxide caustic indicated that local contact

with caustic could result in “extensive damage to tissues, with resultant blindness,

cutaneous burns, and perforations of the alimentary tract,” with potential for

development of “squamous cell carcinomas.” Govt. Ex. 17-7b. The NIOSH report

on inorganic mercury warned of the effects of mercury and mercury vapors to the

central nervous system. Govt. Ex. 17-7c. Dr. Teitelbaum testified that exposure to

caustic could cause burns ranging from first- to third-degree and could be lethal, and

that exposure to mercury could cause mild tremors, personality changes, some

detectable neurological abnormalities, changes in kidney function to severe kidney

damage with potential death, and immune system problems. R20-229, 239-42. Dr.

Teitelbaum opined that the employees were “in danger of death or serious bodily

injury.” R20-248. The evidence was sufficient for the jury to find that the

defendants placed others in danger of death or serious bodily injury.


       33
           Taylor commented that “[j]ust because the trend happened to be the same on two
completely unrelated events, does not necessarily tie them together.” R21-296. He said that he
“noticed a similar trend on two completely unrelated events.” Id. at 297. He admitted “that the
mercury vapor levels in the workplace did increase” and that “drums of dried waste can be a source
of mercury.” Id. at 297-98.

                                                44
                   b. The Evidence of Mens Rea

      The evidence showed that Hansen, Randall, and Taylor knew that the

conditions of the plant were dangerous and that the conditions posed a serious

danger to the employees. LCP former employee Wilbur Duane Outhwaite testified

that he voiced his opposition to the use of the Bunker “C” storage with Hansen, and

that Hansen responded that it was “his decision to make, and he decided to use

them.” R20-350. LCP acting plant manager Hugh Croom discussed his concerns

regarding the dangerous conditions in the cellroom and the danger to the employees

with Randall. R16-129-30. Croom and LCP former employee Outhwaite testified

that Randall received daily reports from the plant managers concerning plant

operations and “safety problems.” R16-97-98; R20-359, 374. Randall was aware of

the water on the cellroom floor and “wouldn’t say that [he] wasn’t unaware of the

hazard,” but thought that the walkway was “an acceptable resolution” to

“eliminating the hazard to the employees while we worked to dry the cellroom

floor.” R21-224-25. He conceded that he was aware that the company was cited for

willful violation of OSHA safety regulations as a result of water on cellroom floors.

Id. at 225; Govt. Ex. 10-7i. Jesse Jones, a former LCP employee and a union

representative, met with Randall to discuss the employees’ safety issues, and

Randall promised the needed repairs. R21-148. He said that he discussed the safety

concerns, specifically “the water condition, the deterioration of the plant with the

                                          45
pipes, the leaks, and the safety equipment[]” with Hansen and Taylor. Id. at 146.

Between 3 August 1993, and 4 February 1994, Randall was sent 22 reports listing

110 different violations of the NPDES standards. Govt. Exs. 10-1o-10-1nn. As

LCP’s environmental manager, Brent Hanson regularly advised Randall of the

plant’s environmental problems “[w]henever he was interested in things” and by

monthly reports. R20-64-65.

      As early as 1988, NIOSH informed Taylor that the plant employees had

“extremely high” levels of mercury in their bodies which created “an unacceptably

high potential for health effects,” and that the mercury-contaminated wastes should

be kept in vapor-proof containers. Govt Ex. 40-1c at 2. Despite this, the employees’

exposure to high levels of mercury continued. In 1992, Taylor addressed his

concerns about “severe safety” problems in a memorandum to Randall. Govt. Ex. 1-

5. Taylor was aware that, during the spring of 1993, 23 cellroom employees were

removed from their duty in the cellrooms due to their high levels of mercury and that

the mercury level in the workplace increased. R21-294-95, 297. Taylor was aware

of and concerned by the mercury-contaminated waste which was stored in drums in

the cellrooms’ basement and which was emitting elevated levels of mercury fumes.

Id. at 298-303. He admitted that the mercury-contaminated mud on the cellroom

floors posed a health risk and needed to be monitored. Id. at 301-02. He testified

that, on occasion, he would get into the water wearing protective equipment to make

                                         46
repairs and improvements to the pumps, and admitted that, if the wastewater got

onto bare skin and was caustic, “you would start to feel a little burning or a little heat

sensation” but that it could be neutralized by washing with the safety solution. Id. at

263-64. He said that such burns were “not unusual” in a caustic soda manufacturing

plant through employee carelessness and equipment failures. Id. at 264.

                    c. Consent to the Risks

      The RCRA knowing endangerment provision can be affirmatively defended if

“the conduct charged was consented to by the person endangered and that the danger

and conduct charged were reasonably foreseeable hazards of–(A) an occupation, a

business, or a profession.” 42 U.S.C. § 6928(f)(3). The evidence showed that the

plant’s environmental violations seriously endangered the employees and were not

typical to chlor-alkali plants. Hugh Croom, the plant manager for the LCP chlor-

alkali plant in North Carolina, testified that the dangerous conditions in the

Brunswick plant were not present in the North Carolina plant because the North

Carolina plant had adequate waste treatment equipment and facility maintenance.

R16-108-09, 127-29; R19-32-34, 52, 107-09. 110-11. He said that he discussed his

concerns regarding the environmental issues, the wastewater treatment system

issues, and the dangers to the employees with Randall and with Taylor. R16-129-30.

LCP environmental manager Brent Hanson noted that, although covering mercury

with water to limit mercury vapors was an accepted practice within the chlor-alkali

                                           47
industry, it was usually practiced “in a little more confined manner” than the

condition of the cellrooms, it was not an industry practice to allow such quantities of

mercury to accumulate on the cellroom floors, and he knew of no other chlor-alkali

plants that permitted such a condition to exist. R20-145, 153. Dr. Teitelbaum

testified that, although he did not think that “you can get a zero risk” in a chlor-alkali

plant, he thought “you can make chlor-alkali plants safe so that workers under

everyday conditions are extremely unlikely to be hurt.” R20-245.34

       The employees also did not freely consent to conditions at the plant. They

complained to management, including Hansen, Randall, and Taylor, about the

dangerous working conditions, and refused to work in the cellrooms. Union

representative and former plant employee Jesse Jones testified that LCP suspended

nine employees who refused to “go underneath the cellroom to repair the pump”

because of the wastewater on the cellroom floor. R21-138-42. Jones said that he

discussed his concerns about the working conditions with Hansen, Randall, and

Taylor. R21-138-39, 146-48. Former employee Larry Barwick said that he

complained “to whoever would listen,” including the LCP management, about the



       34
           He noted that “the Swedish chlor-alkali industry . . . had air levels of 20 or below and
urine levels which almost never exceeded 30" in 1990, demonstrating that such an environment was
possible. R20-245. He explained that a safe environment could be promoted by the use of industrial
hygiene, including “engineering controls, protective equipment, substitution of materials in places
where you can substitute, and administrative controls as to how long and what kind of environments
people work in.” Id. at 246.

                                                 48
fumes35 and visible mercury in the cell buildings.36 R20-319-20. He refused to go

into the cellrooms, and was once sent home for the day based on his refusal. R20-

321. The evidence, therefore, was sufficient to show that the defendants knew that

the plant’s violations of the CWA and RCRA violations were inevitable, that the

plant was incapable of complying with environmental standards, and that the

employees were endangered while working within this environment without

consenting to the risk.

       4. Conspiracy

       Hansen, Randall, and Taylor argue that the district court erred by not granting

their motions for acquittal because the government never proved a conspiracy. They

maintain there was no showing of an agreement between them, the operation of the

plant was a legal act, and they did not pursue the objectives of the conspiracy.

Randall suggests that the evidence showed that he took affirmative steps to improve

compliance. Taylor contends that he was not involved in the operations at the

       35
          Barwick said that:
        [T]he fumes from the acid burners were coming down and you couldn’t breathe
       without wearing a respirator.
               It would burn your skin. It would take the hair off of your arms. It would get
       in your eyes, under your goggles. And everything–it had caustic. It had bleach.
       It had acid fumes. . . . After probably the last year or year and a half, that was
       probably a regular everyday thing almost, that you would get gas somewhere in [the
       cell building]. R20-319-20.
       36
          Barwick testified that the mercury “was everywhere. . . the floors, the ledges, the beams,
any place you had to get up in to to change headers . . . You would have mercury on the beams.
You would have mercury on the floors. When you would take the headers apart, mercury would run
out of them.” R20-320.

                                                 49
Brunswick plant for a significant period of the “conspiracy” and authored several

memos to management expressing his concerns regarding the plant’s operation once

he began working there. He maintains that, after assuming the plant manager

position, he recommended shutting down the plant or at least one of the cellrooms

and, when those recommendations were rejected, he spent several months seeking

money for maintenance. He also argues that the evidence showed that he directed

that the reports be truthful and accurate.

      To obtain a conviction under 18 U.S.C. § 371, “the government must show:

‘(1) the existence of an agreement to achieve an unlawful objective; (2) the

defendant’s knowing and voluntary participation in the conspiracy; and (3) the

commission of an overt act in furtherance of the conspiracy.’” United States v.

Harmas, 974 F.2d 1262, 1267 (11th Cir. l992) (quoting United States v. Cure, 804

F.2d 625, 628-30 (11th Cir. 1986)). “An agreement may be proved by either direct or

circumstantial evidence and a common scheme or plan may be inferred from the

conduct of the participants or from other circumstances.” United States v. Diaz, 190

F.3d 1247, 1254 (11th Cir. 1999). However, it is “essential” “that the object of the

agreement must be illegal.” United States v. Toler, 144 F.3d 1423, 1426 (11th Cir.

1998). “Each party to a continuing conspiracy may be vicariously liable for

substantive criminal offenses committed by a co-conspirator during the course and in

the furtherance of the conspiracy, notwithstanding the party’s non-participation in

                                             50
the offenses or lack of knowledge thereof.” United States v. Mothersill, 87 F.3d

1214, 1218 (11th Cir. 1996) (citing Pinkerton v. United States, 328 U.S. 640, 646-47,

66 S. Ct. 1180, 1184 (1946)). In the usual Pinkerton case, it is not necessary for the

court to inquire into a particular conspirator’s individual culpability, “so long as the

substantive crime was a reasonably foreseeable consequence of the conspiracy.”

United States v. Alvarez, 755 F.2d 830, 849-50 (11th Cir. 1985). It is unnecessary

for the government to prove that each conspirator participated in all aspects of a

conspiracy, knew each phase or every detail of the conspiracy, or knew all of the

participants. United States v. Pedrick, 181 F.3d 1264, 1272 (11th Cir. 1999). A

conspirator may be convicted if he “participates in some affirmative conduct

designed to aid the success of the venture with knowledge that h[is] actions would

further the venture.” Id. A defendant may be convicted of conspiracy if he joined

the conspiracy after its inception and played only a minor role within it, United

States v. Knowles, 66 F.3d 1146, 1155 (11th Cir. 1995), and he is presumed to be a

part of the conspiracy until all conspiracy activity ceases or he proves that he

withdrew. United States v. LeQuire, 943 F.2d 1554, 1563-64 (11th Cir. 1991). To

show withdrawal, a conspirator must show that he “has taken affirmative steps to

defeat the objectives of the conspiracy,” and “made a reasonable effort to

communicate these acts to his co-conspirators or disclosed the scheme to law

enforcement officers.” Id. at 1564.

                                           51
      The indictment charged that, from July 1985 to 1 February 1994, Hansen,

Randall, and Taylor “did knowingly and willfully combine, conspire, confederate

and agree together and with others” to knowingly act in violation of the

environmental laws by “continu[ing] to operate the Brunswick facility” after

learning that they were in violation, storing and disposing of hazardous wastes

without a permit, and submitting “incomplete, inaccurate, and misleading

information” in their reports to the various state and federal regulatory agencies.

R1-1-10-14. The evidence showed that the defendants admitting to sharing the

common goal to operate the plant until a buyer could be found. The jury could infer

from this goal and the defendants’ knowledge of the plant’s continuing problems

with worker safety and environmental compliance that they reached a tacit

agreement to operate the plant in violation of environmental laws. The defendants

knew of the violations from either personal observation or from information that

they received from the plant employees, and frequently communicated with each

other regarding operation of the plant despite the continuous environmental

concerns. The defendants failed to provide the corporate board with information

about the violations, and failed to accurately present the plant’s inability to comply

with the regulations to the Georgia EPD. Each of the substantive offenses were

foreseeable consequences of the agreement to continue operating the plant in

violation of the environmental statutes.

                                           52
      5. Knowledge of the Substantive Offenses

      Randall argues that the district court erred in denying his motion for acquittal

because the government failed to show that he had the requisite “knowledge” of the

CWA and RCRA violations on the specific dates when they occurred. He contends

that his knowledge after the violations had occurred was not sufficient. The statutes

for the violations under which Randall was indicted contain explicit knowledge

requirements. For a conviction under 33 U.S.C. § 1319(d)(2)(A), the defendant must

be shown to have “knowingly” violated various sections of the CWA or permit

conditions or limitations. For a conviction under 42 U.S.C. § 6928(d)(2)(A), the

defendant must be shown to have “knowingly” treated, stored, or disposed of an

identified hazardous waste without a permit. We have held that the knowledge

element is satisfied where a defendant, who may not have “directly” caused a

hazardous waste violation but had “approved of previous dumpings as a way to meet

storage squeezes,”“effectively ordered” a subsequent violation when he instructed a

subordinate to “handle” hazardous waste. United States v. Greer, 850 F.2d 1447,

1451-52 (11th Cir. 1988).

      Here, although Randall did not directly cause the violations, he knew that the

plant was violating its permit on an almost daily basis, accumulating wastes that it

could not treat, and was frequently releasing the wastes from the cellrooms as

needed to keep the plant operational. He received 22 written reports between 3

                                          53
August 1993 and 4 February 1994 advising him of a total of 110 different violations

of the NPDES permit. He received frequent and sometimes daily oral and written

reports from the various plant managers of the plant’s operations and safety

concerns. He knew that the plant was incapable of complying with the

environmental standards and knew that the violations were inevitable. We conclude

that the evidence that Randall permitted the plant employees to process the

hazardous wastes as they had in the past despite his knowledge that the procedures

were in violation of environmental regulations was sufficient to show that Randall

acted “knowingly.”

C. Jury Instructions

      Hansen, Randall, and Taylor argue that the district court’s jury instructions

misstated the reasonable doubt standard, improperly applied the concept of

responsible corporate officer, improperly defined the elements of knowing

endangerment, and effectively eliminated the mens rea requirement from each of

these statutory violations. Hansen contends that the instructions essentially

instructed the jury that they could convict him because of his job title.

      “‘We review jury instructions de novo to determine whether they misstate the

law or mislead the jury to the prejudice of the objecting party.’” United States v.

Grigsby, 111 F.3d 806, 814 (11th Cir. 1997), quoting United States v. Chandler, 996

F.2d 1073, 1085 (11th Cir. 1993). We review the district court’s denial of a

                                           54
requested instruction for abuse of discretion, because a defendant is entitled to an

instruction on a defense theory if it has some basis in the evidence and is supported

by law. Grigsby, 111 F.3d at 814. A defendant cannot challenge a jury instruction

on a ground not raised at trial unless he establishes “plain error” under

Fed.R.Crim.P. 52(b). United States v. Meester, 762 F.2d 867, 879-80 (11th Cir.

1985). If the requirements of Rule 52(b) are satisfied and the instruction was made

in error, is plain, and affected substantial rights, we “may then exercise [our]

discretion to notice a forfeited error, . . .only if . . .the error seriously affect[ed] the

fairness, integrity, or public reputation of judicial proceedings.” Johnson v. United

States, 520 U.S. 461, 466-68, 117 S. Ct. 1544, 1548-49 (1997) (internal citations

omitted). Under the invited error doctrine, we will generally not review an error

induced or invited by a party through the submission of an incorrect jury instruction

to the judge which passed on to the jury. United States v. Stone, 139 F.3d 822, 838

(11th Cir. 1998) (per curiam).

       1. Reasonable Doubt Standard

       Hansen and Randall maintain that the district judge misstated the essential

basis of the convictions by instructing that the government did not have to prove

guilt beyond a reasonable doubt. In his introduction to the jury instructions, the

district judge advised the jury that he would read them the jury charge and would

provide them each a copy of the charge for them to “refer to it at any time you think

                                              55
is appropriate” when they were sent out to deliberate. R22-172. The district judge

then orally instructed the jury on reasonable doubt as follows:

               So the Government always has the burden of proving a
        Defendant guilty beyond a reasonable doubt. If it fails to do so, under
        your oath, you would have to find that Defendant not guilty.
               But while the Government’s burden is a heavy burden, it is not
        necessary that the Defendant’s guilt be proved beyond a reasonable
        doubt, because that is generally impossible. The law does not require a
        mathematical certainty, only the exclusion of any reasonable doubt
        concerning that Defendant’s guilt.
               In that regard, a “reasonable doubt” is defined as a real doubt,
        based upon reason and common sense after a careful and impartial
        consideration of the entire evidence in this case, or the lack of evidence.
               Proof beyond a reasonable doubt, in other words, is proof of such
        a convincing character that you would be willing to rely or act upon it
        without hesitation in a decision involving the most important of your
        affairs. But you take a common sense view. . . .
               You may not find a Defendant guilty unless you find that the
        inferences you draw from the evidence are consistent with the theory of
        his guilt and inconsistent with reasonable theories of innocence. If you
        are convinced that a Defendant has been proved guilty beyond a
        reasonable doubt, say so with a verdict of guilty. On the contrary, if you
        have reasonable doubt, then under your oath, you would have to find
        that Defendant not guilty.

R22-174-75 (emphasis added). No objection was made as to this instruction. R22-

206-09.37

        37
           The government argues that there may be an error in the transcript. Government brief at
23. There is no indication that this matter was submitted to and settled by the district court
consistent with the procedure outlined in Fed.R.App.P. 10(e).
        The district judge provided the parties with an opportunity to “[s]tate [their] exceptions” after
the jury instructions were read. R22-206-09. Taylor’s counsel said he had been “listening
carefully to the charge” and had heard the word “water” used in the place of “wastes.” Id. at 208.
He then noted that the jury “will have it to read.” Id. Taylor’s counsel also observed that the word
“person” had been defined as an “individual corporate officer” instead of a “responsible corporate
officer;” the judge made a curative instruction. Id. at 208-09.

                                                    56
      The passage, as provided to the jury in the written charge, read:

            Thus, while the Government’s burden of proof is a strict or heavy
      burden, it is not necessary that a Defendant’s guilt be proved beyond all
      possible doubt. It is only required that the Government’s proof exclude
      any “reasonable doubt” concerning a Defendant’s guilt.

R6-133-2.

      “[W]e consider [a reasonable doubt] instruction as a whole to determine if the

instruction misleads the jury as to the government’s burden of proof.” Harvell v.

Nagle, 58 F.3d 1541, 1542 (11th Cir. 1995). The jury must be instructed that

defendant’s guilt must be proved by the government “beyond a reasonable doubt” on

each element of the charged offense, but the trial court is not required to define

reasonable doubt. Id. If the trial court defines reasonable doubt, the standard must be

explained correctly. Id. A district court’s failure to submit an element of the offense

to the jury, including an erroneous instruction on reasonable doubt, is a structural

error which defies the harmless-error analysis. Johnson, 520 U.S. at 468-69, 117 S.

Ct. 1544 at 1549-50. Although we have held that “an inadequate reasonable doubt

instruction cannot be cured by other circumstances at trial,” Nutter v. White, 39 F.3d

1154, 1158 (11th Cir. 1994) (reversing a conviction in which the instruction defined

reasonable doubt using the phrase “substantial doubt”), “[j]ury instructions are not

considered in isolation; rather we view them in the context of the entire . . .

proceeding.” Waters v. Thomas, 46 F.3d 1506, 1524 (11th Cir. 1995).


                                            57
      Here, the improper passage is immediately prefaced and followed by a correct

instruction, and the correct instruction was included in the written copy provided to

each juror. The judge stated the correct instruction numerous times, including each

element of each offense to be proven. See R22-172, 173, 182, 185, 187,189, 193-94,

199-201. The instruction, as written and as provided to the jury, was not inadequate

and presented the correct reasonable doubt standard. Viewing this instruction as a

whole and in the context of the entire proceeding, we find that it did not mislead the

jury as to the reasonable doubt standard. See United States v. Torres, 901 F.2d 205,

243 (2nd Cir. 1990) (rejecting a challenge to the language used in one sentence of a

reasonable doubt standard where a correct instruction was provided “immediately

after” the challenged language and provided at least five times in the instructions in

general and as to the specific offenses); but see Bloomer v. United States, 162 F.3d

187, 189, 194 (2nd Cir. 1998) (finding an improper reasonable doubt instruction

constitutionally deficient despite at least 17 proper instructions where there was no

curative instruction to alert the jury to disregard the incorrect instruction.)



      2. Reasonable Corporate Officer

      Hansen and Randall contend that the district judge undermined the jury’s fact-

finding function by directing that they treat the defendants as “responsible corporate

officers” (“RCO”). They maintain that the instruction as given permitted the jury to

                                            58
convict them on the basis of their corporate positions instead of their individual

liability. They suggest that the district court’s separate RCO instruction allowed the

jury to believe that it applied equally to the conspiracy, CWA and RCRA charges.

             The district judge instructed the jury:

             Under the federal Clean Water Act, the definition of a “person”
      specifically includes corporations and individual corporate officers. You
      are instructed that the Defendants, Christian Hansen, Randall Hansen,
      and Alfred Taylor are persons for purposes of the Clean Water Act.

R22-191. Taylor’s attorney objected that “[t]he statute says, ‘ . . . and responsible

corporate officers.’” R22-209. The district judge then explained “[w]herever I have

used the term ‘corporate officers,’ I mean responsible corporate officers.” Id.

      In a CWA case, “the term ‘person’ means . . . any responsible corporate

officer.” 33 U.S.C. § 1319(c)(6).    The RCRA counts require proof that each

defendant “knew” of the violations’ potential for harm and danger. 42 U.S.C. §

6928(e). In United States v. MacDonald & Watson Waste Oil Co., 933 F.2d 35 (1st

Cir. 1991), the First Circuit vacated a conviction under 42 U.S.C. § 6928(d)(1) after

finding that the district court’s instruction, which relied on the RCO doctrine in part

and which instructed “that the officer must have known or believed that the illegal

activity of the type alleged occurred” incorrectly permitted a finding of guilt without

a determination that the defendant possessed actual knowledge of the specific

violation. Id. at 51. The First Circuit reasoned that the RCO doctrine was


                                           59
inapplicable where the defendant was charged under a statute that required explicit

knowledge. Id. 51-55. The Ninth Circuit has held that:

      [U]nder the CWA, a person is a ‘responsible corporate officer’ if the
      person has authority to exercise control over the corporation’s activity
      that is causing the discharges. There is no requirement that the officer in
      fact exercise such authority or that the corporation expressly vest a duty
      in the officer to oversee the activity.

United States v. Iverson, 162 F.3d 1015, 1025 (9th Cir. 1998). Explaining that “[t]he

relevant inquiry is whether the instructions as a whole are misleading or inadequate,”

the Ninth Circuit rejected the defendant’s argument that the RCO “instruction

allowed the jury to convict him without finding a violation of the CWA.” Id. at 1026.

The district judge had stated the elements needed for the government’s proof and told

the jury that the CWA “‘also holds accountable’” RCOs. Id. The Ninth Circuit

found the instructions not erroneous, reasoning that “the [RCO] instruction relieved

the government only of having to prove that defendant personally discharged or

caused the discharge of a pollutant” and that “[t]he government still had to prove that

the discharges violated the law and that defendant knew that the discharges were

pollutants.” Id. We find this issue meritless. The clarifying instruction given by

the district court was requested by the defendants. The district court’s instruction on

responsible corporate officer was not given as to the CWA counts, Counts 2-21, but

was given only as to Counts 22-34.

      3. Knowing Endangerment

                                           60
      Hansen argues that the instructions authorized the jury to convict him of

knowing endangerment without making a determination that he knew of an imminent

danger. Hansen requested that the instruction include the “element of knowingly” on

“each element of the offense” to insure that the jury understood that the charges were

related to “individual, personal, knowing, knowledgeable, deliberate conduct.”

R22-53-55. The district judge noted that the preface to the instructions included

“knowingly” and agreed that he would add an instruction that “[t]he term knowingly

is applicable to each element of the offense.” Id. at 54, 56. Hansen’s attorney

responded “[t]hat would help, Judge.” Id. at 56. Later, the government requested

that the instructions for “willful” be limited to count 1 and that the instructions for

“knowingly” apply to the remaining counts. Id. at 70-71. Hansen’s attorney stated

that he “strongly disagree[d],”but the judge indicated that he would permit the

instruction, as clarified, to stand. Id. at 71. At the end of the charge conference,

Hansen’s attorney renewed his objection to the district judge’s failure to give the

knowing instruction as to each offense. Id. at 206-07. Because the instruction

required that the jury find that Hansen knew that the violations could cause imminent

danger, this argument is meritless.

      4. Mens Rea Requirement

      Hansen argues that the instructions permitted the jury to convict him of the

RCRA violations without making factual findings that he had knowledge of the

                                            61
RCRA elements of hazardous materials, permit regulations, and the treatment,

storage, or disposal of hazardous wastes. He maintains that the instruction

reinforced the government’s position that Hansen should be convicted because LCP

was his company, and not based on the legally required relationship between Hansen

and the violations. During the charge conference, Randall’s attorney objected to an

instruction as to Counts 22-34, arguing that it should be limited to Counts 22-33,

because Count 34 had additional elements. R22-59-63, 65-66. He asked that an

instruction be added limiting liability to knowledge possessed by the defendant

himself, and the district judge responded “[a]ll right. All right. We will add that.”.

Id. at 61.

       During closing argument, the government stated:

              Chris Hansen is a hands-on manager. You heard discussions of
       how he ran the plant. I would submit it was probably his way or the
       highway. Does anybody doubt he would have known what was going
       on at every place in the plant? He was there. He ordered the Bunker C
       tanks to be filled.

R22-99-100. The district judge explained that:

        a person acts knowingly if he acts intentionally and voluntarily,
       realizing what he is doing, and not because of ignorance, mistake,
       accident, or carelessness. Whether a Defendant acted knowingly may be
       proven by the Defendant’s conduct and by all of the facts and
       circumstances surrounding the case.

Id. at 188. Addressing the RCRA counts, the district judge instructed:

             Each count charges the . . . Defendants, all of them, unlawfully

                                           62
      treated, stored, or disposed of one or more hazardous wastes without the
      required permits.
             Now in order to prove a Defendant guilty of those charges, the
      prosecution must establish the following essential elements:
             First, that on or about the date charged in Counts 22 through 34,
      the Defendant under consideration knowingly treated, stored, or
      disposed of one or more of the solid wastes listed in those counts;
             Next, that such solid wastes were listed or identified under RCRA
      as hazardous wastes; and
             Third, that the wastes were treated, stored or disposed of at a
      location which did not have either interim status or a RCRA permit
      authorizing the treatment, storage or disposal of such wastes.

Id. at 192. The district judge also charged that “the Government must prove beyond a

reasonable doubt that the Defendant under consideration knew that substances

involved in the alleged offenses had the potential to harm others or the environment.”

Id. at 193. The district judge continued:

             Now each Defendant may be found guilty of Counts 22 through
      34 of the Indictment if you find that the Government has proven the
      following beyond a reasonable doubt:
             First, that the Defendant under consideration had a responsible
      relationship to the violation–that is, that it occurred under his area of
      authority and supervisory responsibility;
             Second, that the Defendant had the power or the capacity to
      prevent the violation; and
             Third, that the Defendant acted knowingly in failing to prevent,
      detect or correct the violation.

Id. at 200-01. Randall’s counsel renewed the objection that the instruction as to

Count 34 was erroneously included because it could not be based on constructive

knowledge. Id. at 207.

      We have held that a defendant’s “knowledge [as to whether a site has a permit

                                            63
or the disposal of hazardous waste] does not require certainty, and the jurors may

draw inferences from all of the circumstances, including the existence of the

regulatory scheme.” United States v. Hayes Int’l Corp., 786 F.2d 1499, 1505 (11th

Cir. 1986) (reviewing a conviction under 42 U.S.C. § 6928(d))(1)). As to Count 34,

RCRA’s knowing endangerment provision also requires proof that the hazardous

waste violation placed persons in “imminent danger of death or serious bodily injury”

and that the defendant had knowledge of that danger. 42 U.S.C. § 6928(e). Because

the instructions clearly set forth that a finding of “acted knowingly” was required for

a conviction, there was no error in the instruction.

      5. Wastewater Treatment System

      Hansen contends that the instructions allowed the jury to convict him under the

CERCLA release offenses without a finding that he knew the quantity of the

materials released or was meaningfully in charge at the time of the release. Taylor

argues that, because the instruction failed to include the definition of “tank,” it

allowed the jury to consider the cellroom as a part of the wastewater treatment

system. In his request for a charge as to Counts 35 through 40, Hansen asked that

the jury be instructed that it could not convict him unless he was the person in charge

at the time of the release and knew that the released hazardous materials exceeded the




                                            64
applicable reportable quantity. R4-98, Request to Charge No. 23.38

       The district judge instructed the jury:

              Now Counts 35 through 41 charge the Defendants, Mr. Christian
       Hansen and Mr. Taylor with violations of the Comprehensive
       Environmental Response, Compensation, and Liability Act, which is
       known by the acronym CERCLA, which requires the immediate
       reporting of the release of a reportable quantity of a hazardous substance
       into the environment.
              ...
              To establish a violation of this Act, as alleged in Counts 35
       through 41, the Government must prove the following elements beyond
       a reasonable doubt as to each Defendant:
              First, that the Defendant was one of the “persons in charge” of a
       facility;
              With respect to Counts 35 to 40, that a reportable quantity of
       mercury contaminated wastewater–that is, more than one pound of
       wastewater contaminated with mercury and other hazardous
       substances–was released into the environment within a 24 hour period;
              As to count 41, that a reportable quantity of chlorine–that is, in
       excess of 10 pounds–was released into the environment within a 24 hour
       period; and
              That the Defendant under consideration failed to notify
       immediately the National Response Center of the release of such
       materials as soon as he had knowledge of the release.
              CERCLA’s reporting requirements are not extended to all
       employees involved in a release. The reporting requirements apply to
       any person–even if of relatively low rank–who was in a position to
       detect, prevent, and abate a release of the hazardous substances.

       38
          Specifically, Hansen requested that the charge read:
              First, that on the date alleged in each respective count, Christian Hansen was
       a “person in charge of a facility,” as that term is defined by law;
       ...
              Fourth, that Mr. Hansen (1) knew that the described release had occurred, (2)
       knew that the wastewater released contained a reportable quantity of mercury, and
       (3) knew that the release was not allowed by any federal permit.
R4-98 at Charge 23.


                                                 65
              ...
              A “person in charge’s” control over a facility need not be sole or
       exclusive. There may be several “persons in charge” of the same
       facility. It is only necessary that the individual have or share such
       control of the facility where the release occurred.

R22-201-02.

       In clarifying the definition of “operator” under CERCLA, the Supreme Court

instructs that “an operator is simply someone who directs the workings of, manages,

or conducts the affairs of a facility . . . specifically related to pollution, that is

operations having to do with the leakage or disposal of hazardous waste, or decisions

about compliance with environmental regulations.” United States v. Bestfoods, 524

U.S. 51, 66-67, 118 S. Ct. 1876, 1887 (1998). The district court’s instructions

required that the jury find that the defendant under consideration knew of the release

and knew that the release contained hazardous waste, and failed to report it.

       There is no indication in the record that Taylor requested an instruction on the

definition of “tank.” Hansen requested an instruction on the existence of the

wastewater treatment exemption to the 90-day labeling and disposal period.39 R22-

68-69. The judge subsequently included such an instruction:

               Tanks which are part of a wastewater treatment system that is

       39
             Hansen’s counsel explained that he “just want[ed] the jury to understand that if the water
is handled through the wastewater system, it’s exempt from the ninety-day labeling and all these
other things.” R22-69. The government counsel responded: “If it’s in a tank. It needs to be clear
that if it’s in a tank and it can be treated in a wastewater system–.” Id. The district judge asked that
the language be provided to him in writing, and Hansen’s counsel agreed to do so. Id.

                                                    66
      subject to regulation under the CWA need not have a RCRA permit so
      long as they are used for the treatment of wastewater. Therefore,
      wastewater which is being held temporarily in such tanks is not subject
      to these RCRA permitting requirements.

Id. at 199.

      A “tank” is defined by the regulations as “a stationary device, designed to

contain an accumulation of hazardous waste which is constructed primarily of non-

earthen materials (e.g. wood, concrete, steel, plastic) which provide structural

support.” 40 C.F.R. § 260.10. Although Taylor maintains that the instruction would

have helped the jury understand that the cellroom was a tank and part of the

wastewater system, the evidence showed that the berms, used in the cellroom to

contain the wastewater, were constructed of dirt. R19-256. Taylor neither requested

a definition of “tank” in the instructions nor was prejudiced by the failure to of the

court to provide it.

E. Sentencing Guidelines

      We review the district court’s factual findings for clear error and its

application of the law to those facts de novo. United States v. Quinn, 123 F.3d 1415,

1424 (11th Cir. 1997).

      1. Downward Departure

              a. Christian Hansen

      Hansen argues that the district court erred by concluding that it lacked the


                                           67
authority to depart under U.S.S.G. § 5K2.0. He maintains that, at a minimum, the

district court was ambiguous as to whether it believed that it had the authority to

grant a downward departure and that any ambiguity must be resolved in his favor.40

       At sentencing, Hansen argued, inter alia, that he should be granted a downward

departure pursuant to U.S.S.G. § 5K2.0 because the factors of the case took it outside

of the heartland of cases to which the guidelines apply. R13-5-8. He argued that a

departure was warranted because the government agencies monitored and knew of

the environmental violations, and that this situation was not where Congress intended

to impose the high penalties for environmental violations. Id. at 6. After sentencing

Hansen, the district judge stated that he “d[id] not really find any actual basis for a

departure from the guidelines, even though I might, if I had discretion, found

otherwise.” Id. at 52.

        We “generally may not review the merits of a district court’s refusal to grant a

downward departure, [but] may conduct a de novo review of a defendant’s claim that

the district court mistakenly believed it lacked the authority to grant such a

departure.” United States v. Mignott, 184 F.3d 1288, 1290 (11th Cir. 1999) (per



       40
            Amicus curiae The Washington Legal Foundation also raises the issue that Hansen’s
sentence must be vacated because the environment sentencing laws were unlawfully promulgated
and impose patently unreasonable sentences. However, this issue was not considered before the
district court and will not be considered on appeal. United States v. Allegheny-Ludlum Indus., 517
F.2d 826, 840 n. 13 (5th Cir. 1975) (noting that it would not consider issues briefed by amicus
curiae which were not raised in the district court).

                                                 68
curiam). Where the district court expresses ambivalence about its authority to depart

from the guidelines, we review the record to determine the district court’s

understanding. See United States v. Webb, 139 F.3d 1390, 1394-95 (11th Cir. 1998)

(noting that “our independent review of the sentencing transcript reveals that the

sentencing judge, at the very least, was bewildered and ambivalent as to whether the

guidelines authorized a downward departure” and that “on balance, . . . the record

more strongly suggests that the court believed that it was not authorized to depart

downward.”). If there is no indication that the district court misapprehended its

authority, “we assume that the sentencing court understood it had authority to depart

downward.” United States v. Chase, 174 F.3d 1193, 1195 (11th Cir. 1999).

      Hansen was sentenced after Randall. During Randall’s sentencing hearing, the

district judge acknowledged his authority to depart. R9-9. Hansen’s sentencing

transcript shows that the district judge permitted extensive discussion of whether the

circumstances of Hansen’s case were outside the heartland of cases to which the

guidelines had been applied, and that neither party argued that the district court

lacked the authority to depart downward. There is nothing in the record that shows

that the district court misapprehended its authority to depart downward. Therefore,

we assume the sentencing court understood its discretionary authority to grant a

downward departure but decided not to exercise that authority. Id. at 1195. Because

the district court understood that it had the authority to depart, we are unable to

                                           69
review the district court’s denial of Hansen’s request for a downward departure.

               b. Randall Hansen

        Randall contends that the district court erred in not granting his requests for a

downward departure under §§ 5K2.0 and under 5K2.11. As to a departure under §

5K2.0, he argues that his case fell outside the heartland of other environmental

prosecutions and that he was at all times operating under the authority of the U.S.

Bankruptcy Court and upon the advice of his environmental counsel. As to a

departure under § 5K2.11, he maintains that the district court erred in concluding that

financial factors were not a “perceived greater harm” which could trigger a departure

and in not understanding that the record supported his belief that a greater

environmental, as well as economic, harm would occur at the site and in the

community if the plant failed to remain operational.41

        At Randall’s sentencing, the district judge stated:

             [T]he Court acknowledges that it does have authority to depart
       from the guidelines pursuant to [§§ 5K2.0 and 5K.211] if it finds that the



       41
            Randall also argues that the sentencing guidelines, as applied to environmental crimes,
are arbitrary and were unlawfully promulgated. Randall did not raise this issue at the sentencing
hearing but addressed it in a supplemental memorandum in aid of sentencing. R9-228-8. Randall’s
sentencing hearing initially commenced on 2 June 1999, and was continued on 1 July 1999. On 1
July 1999, the hearing was called to order at 10:01 AM, and recessed at 10:24 AM. The
supplemental memorandum is not referenced at the sentencing hearing and was filed at 12:11 PM
on 1 July 1999. Therefore, it does not appear that this was considered by the district court. Because
the issue was not considered by the district court, it will not be considered by this court. Fed.
Deposit Ins. Corp. v. Verex Assurance, Inc., 3 F.3d 391, 395 (11th Cir. 1993).

                                                  70
       circumstances of this case warrant such a departure.42



       42
           It appears that, although the district judge did not find that the circumstances warranted
a departure, he nonetheless considered Randall’s arguments. During the hearing, the district judge
continued:
                As to the Defendant’s arguments concerning lesser harm, I’m not particularly
        impressed with that. For the Court to consider a departure under this section
        [§5K2.11], the Court would have to find either that the Defendant committed the
        crime in order to avoid perceived greater harm or that the Defendant’s conduct does
        not cause or threaten the harm or evil sought to be prevented by the laws prohibiting
        the offenses at issue.
                Now as to that first prong, the Defendant has failed to produce evidence,
        other than his own statement, that closing the LCP plant would have caused a greater
        harm than allowing it to continue operating in the unsafe manner. His argument, as
        I understood it, is based upon financial reasons. As I recall, he stated that there was
        compelling societal interest in keeping the plant open and its three hundred
        employees working.
                While sympathetic to the plight of the employees who would have, and
        eventually did, lose their jobs, that does not, and I do not believe that it justifies
        subjecting the employees and the community to the risk of operating an unsafe chlor-
        alkali plant.
                The Court finds that financial factors are not a perceived greater harm. And,
        therefore, no downward departure is warranted in that instance.
                As to the second prong, the guidelines permit a downward departure where
        the conduct may not cause or threaten the harm or evil sought to be prevented by the
        law prescribing the offense at issue.
                The environmental laws for which the Defendant was convicted were enacted
        to protect human life in the environment. Therefore, the Defendant’s conduct was
        the type of conduct which the environmental laws sought to prevent. And as such,
        the Court finds that the circumstances of this offense do not warrant a downward
        departure under 5K2.11 of the guidelines.
R14-9-11.
        As to the request for a departure under § 5K2.0, he stated:
                [I]n order for the Court to find that the Defendant’s case falls outside the
        heartland, the Court has to find that this is an unusual case where there is something
        atypical about the Defendant or the circumstances surrounding the commission of the
        crime. I simply cannot make such a finding.
                I find that the circumstances of these offenses are those contemplated by the
        Sentencing Commission in the formulation of the guidelines. And further, I find that
        there are no factors which take this case outside the heartland of the environmental
        guidelines. Accordingly, the Court finds that no departure is warranted under 5K2.0
        of the guidelines.
Id. at 11.

                                                  71
R9-9. He set forth the requirements for a departure under the guidelines, but found

that no departure was warranted under either provision.

      We may not review a district court’s refusal to grant a downward departure

unless the court mistakenly believed that it lacked the authority to grant such a

departure. Mignott, 184 F.3d at 1290. Despite Randall’s argument to the contrary,

the district judge indicated his understanding that financial factors could be a

“perceived greater harm” by weighing the harms associated with closing the plant

and putting 300 employees out of work against keeping the plant open as an unsafe

chor-alkali plant and keeping the employees working, but found that the financial

factors were not a harm greater than the harms associated with the operation of an

unsafe chlor-alkali plant. R14-9-11. Because the district court acknowledged that it

had the authority to depart, we lack the jurisdiction to review the decision.

              b. Taylor

      Taylor also argues that the district court erred by not granting him a downward

departure under §§ 5K2.0 and 5K2.11. As to the request for a departure under §

5K2.0, he maintains that his case fell outside the heartland of environmental cases.

As to the request for a departure under § 5K2.11, he contends that he believed that

closing the plant would cause a greater environmental harm that continuing

operations.



                                           72
       Taylor presented each of his issues at sentencing.43 R12-20-21. The district

judge asked the probation officer to comment on Taylor’s requests for a departure,

and to specifically address Taylor’s cooperation during the cleanup efforts. Id. at 21-

22. The probation officer responded that there were no grounds for a downward

departure.44 Id. at 41. The district judge commented:

       I am equally bound by the guidelines and by the law. And I do not have
       much discretion.
       ...
             And I just cannot find a basis for departure under the guidelines,
       inasmuch as the facts as found are of the kind contemplated by the
