That’s why we are dedicated to doing our important THE work as safely, efficiently and CEO responsibly as possible.”

Fellow shareholders and neighbors,

At Marathon Petroleum Corporation, we are proud of the work we do. Our 30,000 employees manufacture, transport and market fuels and other products that make people’s lives better in innumerable ways.

Our fuels power the farm equipment that plants and harvests our food. Our fuels move the trucks, trains, ships and aircraft that bring food and other goods to within a quick drive of your homes. The freedom we all enjoy to transport ourselves to work, school and recreation is fundamental to our way of life, and MPC is proud to produce the fuels that empower us with that mobility. The asphalt we manufacture paves roads and is a main component of asphalt shingles. The petroleum coke from our refineries provides fuel for steel mills and powers electric plants. We manufacture petrochemicals that help make insulation, plastics, paints, inks and much more.

Every one of us at MPC cares about our friends, neighbors, co-workers and the environment we all share. That’s why we are dedicated to doing our important work as safely, efficiently and responsibly as possible.

Sincerely,

Gary R. Heminger President and Chief Executive Officer

This mandate organizes biofuels into four rising prices, the LIFO accounting method results separate categories based on their greenhouse in better matching of costs and revenues, because gas emissions.

MPC has consistently demonstrate compliance with the standard.

The proposal would require The unintended consequence of the biofuels MPC and other companies like us to recalculate our mandate is that the refining industry is burdened inventory values and the resulting tax liability using with an inflexible requirement to add more and a different accounting method, and then pay tax on more corn ethanol to a gasoline pool that has been the difference.

bbl.: Barrel (42 U.S. gallons) bpcd: Barrels per calendar day. This is an average of how much crude oil or other feedstock a plant processes over a period of time, divided by the number of days in that period. bpd: Barrels per day Btu: British thermal unit. A measure of heat energy often used to quantify the energy in different types of fuel. For example, gasoline has 124,300 Btu per gallon, and ethanol has 84,500 Btu per gallon.

Carbon dioxide equivalent. Because various greenhouse gases have heat-trapping effects that are CO2e: stronger or weaker than carbon dioxide (CO2), they are often expressed as the equivalent amount of CO2 to provide a consistent measure. DAR: Days Away Rate. An OSHA term representing the number of full days of work missed by employees due to injuries, per 200,000 work hours. DEI*: Designated Environmental Incident. A metric adopted by MPC to capture several categories simultaneously. It includes releases to the environment (including to air, land or water), permit exceedances and agency enforcement actions. MPC ranks DEIs in terms of their severity, with Tier 4 being the most severe, and Tier 1 being the least. Below are partial descriptions of the DEI Tiers: Tier 4 • Release of oil or other hazardous material onto the land greater than or equal to 1,000 bbl. • Release of oil or other hazardous material to a regulated water body greater than or equal to 100 bbl. • Reportable release to air of a hazardous material greater than or equal to 100 times the reportable quantity Tier 3 • Release of oil or other hazardous material onto the land greater than or equal to 100 bbl. but less than 1,000 bbl. • Release of oil or other hazardous material to a regulated water body greater than or equal to 10 bbl. but less than 100 bbl. • Reportable release to air of a hazardous material greater than or equal to an established reportable quantity but less than 100 times the reportable quantity Tier 2 • Release of oil or other hazardous material onto the land greater than or equal to 10 bbl. but less than 100 bbl. • Safety system failure or bypass • Release of oil or other hazardous material into a regulated water body greater than or equal to 1 bbl. but less than 10 bbl. • Release to air of a hazardous material greater than or equal to 80 percent of a reportable quantity but less than an established reportable quantity Tier 1 • Release of oil or other hazardous material onto the land that is less than 10 bbl.

Below are detailed descriptions of the PSE Tiers: Tier 1 • Loss of primary containment (LOPC) of a liquid or gas • Fatality, lost-time injury or community evacuation • Fires exceeding $25,000 in damages

Tier 2 Tier 1

• LOPC of a liquid or gas LOPC Events of Greater Consequences • Results in recordable injury • Fires exceeding $2,500 in damages Tier 2

LOPC Events of Tier 3 Lesser Consequences • Operating outside of system parameters • Safety system failure or bypass, “not-to-exceed” Tier 3 Severity alarm level exceeded Challenges to Safety Systems • All other fires resulting from LOPC Tier 4

Tier 4 Operating Discipline & Management System • Overdue recommendations and mechanical inspections Performance Indicators • Management of change not well executed

Responsible Care®: A program of the American Chemistry Council designed to continually improve performance in the areas of health, safety, environmental protection and more. Companies that choose to participate in Responsible Care undergo audits of their headquarters and facilities to ensure they have a structure and system in place to measure, manage and verify performance. Tonne: Metric ton. While a ton is 2,000 pounds, a tonne (or metric ton) is 2,205 pounds. TRI: Toxic Release Inventory. This includes releases of toxic materials to air, water and land, as well as off-site disposal. The TRI we are required to report to the EPA also includes materials we send off-site for recycling, energy recovery and other forms of further treatment; however, we do not report these latter metrics in this publication.
