If a human player chooses to return a pollutant from the processing hub to the ocean, rather than a collector, are there restrictions on how the player returns the ball to the playing field?
Please see rule E09: “These POLLUTANTS must be returned to play in one of two ways: A. Returned to the OCEAN over the CLEANUP CREW STATION GUARDRAIL. POLLUTANTS should be placed in the OCEAN close to the CLEANUP CREW STATION GUARDRAIL and may not be thrown or rolled by the HUMAN PLAYER into the OCEAN.”
