(18) “Operator” means a person or entity that has legal possession of equipment or vehicles, as determined by DEQ, and uses the equipment or vehicles for construction activity. (19) “Public Highway” has the meaning given that term in ORS 825.005. (20) “Tier 0 Engine” means an engine not subject to the requirements in 40 C.F.R. Part 1039 and that was not subject to previous requirements in 40 C.F.R. Part 89. (21) "Voluntary Participant" means a person that voluntarily applies for an ECL under this division.
