A tank has an individual rated capacity of 120 gallons and an aggregate capacity of 1,000 gallons on a vehicle requiring a Class B CDL. Under Michigan's manual, how should this be treated?

1. Tank endorsement threshold is met
2. No endorsement is needed because each tank is under 500 gallons
3. No endorsement is needed unless the liquid is hazardous
4. It only counts if the tanks are permanent
