MPC CITIZENSHIP REPORT 201322

We are uncompromising in our approach to health and safety, and to our vision: that every day is accident-free, and every employee and contractor at our facilities goes home injury-free. Health and safety are therefore built into our daily work, whether it’s in office buildings, at refineries and terminals, on marine vessels or in vehicles.

Health and safety are important to our success as a company; if our employees and contractors are not safe, then other measures of success lose their meaning. We track the metrics reported in this section as a matter of accountability to our employees and contractors and to the communities in which we live. We want you to know how we’re doing.

MPC SAFETY PERFORMANCE INDEX (MSPI)*

DISCUSSION: The 2013 Wellness Assessments revealed a 33 percent reduction in the number of employees with the largest number of health risks compared to a baseline survey conducted in 2007. In order to ensure statistically valid comparability, MPC selects the assessment population each year to control for attrition and other changes in the group over time.

* The MSPI is a safety metric similar to the OSHA Recordable Incident Rate and Days Away Rate metrics reported in this section, but is weighted for severity. 2012 was the first year that the MSPI was used as one of the criteria to determine a portion of employee compensation.

DISCUSSION: The increase in process safety events in 2013 is a concern that MPC is addressing. For each process safety event that takes place in the company, an in-depth analysis is conducted to determine the causes and how to avoid them in the future. These analyses are then provided to all impacted employees to ensure widespread awareness, and changes are made to processes and procedures as necessary. MPC also is involved in an industry-wide effort to share process safety lessons for continual improvement.

Metrics

HEALTH & SAFETY

DISCUSSION: As MPC grows, we work to ensure every aspect of our business performs to our high safety standards and continually improves. The increase in our MSPI in 2013 is due primarily to the expansion of our business, and our target remains continual improvement in health and safety.

*Excludes Speedway

For more information about any of the terms on this page, please see the Glossary on page 44.

DISCUSSION: The OSHA Recordable Incident Rate represents the number of incidents per 200,000 hours of work. The Days Away Rate represents injuries that caused at least one missed day of work, also per 200,000 hours of work.

MPC CITIZENSHIP REPORT 2013 23

◗ MPC’s refineries in Garyville, La.; Detroit, Mich.; Robinson, Ill.; Catlettsburg, Ky.; Texas City, Texas; and Canton, Ohio, earned the Meritorious Safety Performance Award from the American Fuel and Petrochemical Manufacturers. The award recognized the plants’ excellent safety records.

◗ A seven-member MPC pipeline construction and maintenance crew accrued more than 1,000 workdays with no OSHA recordable injuries, a significant milestone for a crew that conducts excavation work with heavy equipment in all kinds of weather.

◗ MPC’s Marathon Pipe Line subsidiary hosted members of the Tallahatchie County Local Emergency Planning Committee for a pipeline safety and awareness meeting in Charleston, Miss. Topics addressed by MPC

technicians included what to do in the event of a pipeline emergency and what products are shipped through local pipeline systems.

◗ When contractors performing MPC pipeline right of way work incurred four OSHA recordable injuries in 2011, MPC decided to hold a safety summit. In 2012, there were no OSHA recordables. In 2013, the safety summit continued, bringing together MPC employees and contractors working on right of way clearing to engage in hazard-awareness training and receive copies of the new “Best Practices Right of Way Handbook: Think, then Act.”

◗ MPC’s Safe Digging School Program in 2013 reached hundreds of students, their teachers and parents at schools in areas where the company has significant pipeline operations. Through the

program, MPC employees teach children the importance of calling 811 before digging to protect their families, the environment and underground utilities.

◗ To recognize the safety practices of locations with more than 20,000 exposure hours worked, the American Chemistry Council presents Certificates of Excellence to member companies that have no fatalities, no injuries resulting in missing a day of work, and no injuries resulting in restricted duty. MPC earned these certificates at 42 of its operations locations.

◗ MPC earned Norfolk Southern railroad’s Thoroughbred Chemical Safety Award in 2013, in recognition of MPC’s rail operations resulting in zero non-accident releases. A non-accident release is one that is not associated with a train accident.
