They Blend it through the loading arm. There are different lanes you can load on in the terminal and each lane allows you to pull a certain product depending on what loading number you enter. There has been cases where the loading arm was not adding a blend into the truck and the terminal operators will get a message from the system in their office if it's not blending correctly. We have had to use their blend chart and add the blend seperately with a Chevron Rep watching us to make sure we were blending it correctly.
