Welcome to MPC’s refinery contractor
This website provides you with the steps that all contractors are required to complete in order to enter and do work any of the six refineries owned by Marathon Petroleum Corporation (MPC). Our refineries are located in Canton, Ohio; Detroit, Michigan; Robinson, Illinois; Texas City, Texas; Garyville, Louisiana and Catlettsburg, Kentucky. Since some variation does exist in the requirements for contractors at the different MPC refinery locations, be sure to select the appropriate refinery from the navigation bar on the left to begin this process.
Important note: Before any contractor or their personnel will be allowed to enter refinery property, ALL of the steps described on this site must be completed.
Note: Many MPC contractors also do work for the Transportation and Logistics (T&L) organization. To view the T&L policies, procedures and requirements for contractors and subcontractors, go to:
