You might want to check with either your local or state auto dealers' association. The laws / regulations vary sometimes even by county and municipality on something like this.
Check with your current waste oil disposal company. Out in southern california our waste disposal companies handle gas tanks for us and meet our state's requirements. Most important is any company you choose has the proper authorization to handle them.
