• removed the capability of oil tank levels to be visually determined (CSA B139.1.0);
• requirements added for permanent structure for fill point access (CSA B139.1.0)
• removal of Annex C due to CSA B140.2.3 being withdrawn (CSA B139.1.0);
• removal of Annex E due to overlapping requirements in the CSA B140 host of standards (CSA B139.1.0);
• clarification to 45 L capacity for integral supply tanks (CSA B139.1.1);
• additional requirements that take into consideration site conditions on tank oil temperatures (CSA B139.1.1);
• requirements for engine exhaust stack locations (CSA B139.1.0 and CSA B139.1.1);
