After purchasing an old automobile repair shop, Jerry Huxley hires a crew to clean up the shop. The crew finds numerous rusty unmarked cans containing unknown liquids. These cans, along with various other junk and garbage, are loaded onto the bed of Huxley’s pickup truck and hauled to the county landfill. At the landfill, Huxley signs a form certifying that none of the cans contains any hazardous waste. Subsequently, Huxley is indicted under the 42 U.S.C.A. § 6928(d)(1) for “knowingly transporting hazardous wastes, including various industrial solvents and petrochemicals, to an unpermitted facility.” What will be Huxley’s defense?
