Magellan’s Asset PortfolioPetroleum products pipeline system

Longest pipeline in U.S. (8,500 miles)

Access to greater than 40% of refinery capacity in continental United States

Total of 81 petroleum product terminals in 22 states45 terminals connected to Magellan Pipeline, 27mm barrels storage

Marine terminals7 locations with 22 million barrels storage

Inland terminals29 locations with 6 million barrels storage; connected to 3rd party pipelines

Ammonia pipeline system (1,100 miles)

Magellan Pipeline – Refined Products

Significant Market PresenceOklahoma, Missouri, North Dakota, Kansas, Nebraska, Iowa, Minnesota and South Dakota

5

Pipeline FundamentalsPipelines are the most cost efficient and safest method of

transporting liquid fuelsTariff from Houston to Kansas City about 6 cents per gallonCommon Carrier vs. Proprietary Pipeline

Magellan’s open stock systemProduct batching…gasoline / diesel / jet fuelBoutique fuels require incremental infrastructure and

creates capacity limitations due to scheduling inefficiencies

Today, ethanol is transported via truck, rail, barge and ship. Blending takes place at terminals

6

Ethanol Blending at Terminals We have ethanol blending at 35

terminals today (and planning for more)

Ratio Blending Gasoline and ethanol

blended proportionally as the blended fuel enters the truck

Sequential Blending Ethanol enters the truck first

followed by gasoline Ratio & Sequential systems

promote quality blends Total ethanol blending

infrastructure costs $2 to $3 million per terminal

Railcar offloading infrastructure substantially higher

7

Ethanol & Pipelines As domestic and international ethanol production continues

to increase, the economic viability of domestic pipeline shipments increase as well

The introduction of ethanol into the pipeline system brings challenges and opportunities

Commercial opportunities include the potential shipment of 10% ethanol blends as well as fuel grade ethanol

The challenge is related to the potential incompatibility of fuel grade ethanol with the existing pipeline infrastructure Unknown short and long term risks to the operation and system

integrity of the pipeline Urgent need to study the viability of transporting low level

ethanol blends (10%) via our existing pipeline system

8

Technical Issues Technical factors regarding transportation of ethanol by

pipeline Moisture Materials compatibility Stress Corrosion Cracking (SCC)

SCC is the formation of brittle cracks in a material that occurs as a result of corrosion processes and stress

SCC historically found in pipelines and tanks that are in dedicated ethanol service

Cracks develop around steel construction with high bendsWelds with high stress

Historical data suggests SCC appears at distribution terminals (not ethanol plants)

Ethanol Transportation via Multi-Products or Dedicated Pipeline Other important factors Economics

A pipeline from the Midwest to the east coast could be a multi-billion dollar project

Approximate transportation rate per gallon for a 12” line could be as high as 25cpg. A 12” line could move up to 100,000 barrels per day (4.2 million gallons per day)

Commercial Viability Our ability to secure long-term shipper commitments

11

Ethanol Pipeline Logistics

Individual production facilities are small relative to volumes necessary to support a pipeline

Average ethanol plant produces 3,417 barrels per day*

Aggregation facility of up to 100,000 barrels per day (supply from 30 average size ethanol plants)

Distribution terminals at the terminus of the pipeline

Study Underway Association of Oil Pipelines (AOPL) and the API

working with the Pipeline Research Council International (PRCI)

Multiple research projects underway to resolve the technical issues associated with pipelining ethanol Short term (6 to 12 months) - what level of ethanol blends

are compatible with existing pipeline systems with little or no modification

Long term (36 to 48 months) – • identify the environmental factors that produce SCC in ethanol

pipelines and terminals• SCC susceptibility in existing batched pipeline systems• Design requirements for new, dedicated ethanol pipelines

13

House and Senate Energy bills include a provision which provide funds to study the feasibility of an ethanol pipeline

The Senate Finance Committee passed its Energy Tax title which include a provision to allow the transportation of ethanol and biodiesel blends as “qualifying income” for publicly traded partnerships Important to maintain partnership status

Congressional Action

14

Pipelines remain the most reliable, safe and economic mode to transport large volumes of liquid energy

Because of the increasing domestic and international ethanol production base, pipelines may provide an economic method of transportation for ethanol

SCC challenges must be resolved Magellan is actively involved with other pipeline

industry leaders in finding technical solutions AOPL and API members are funding research to address SCC Congress may provide funding for additional study

Transportation of ethanol blends via pipeline may be feasible in the short term Would eliminate the need for costly rail offloading

infrastructure at terminals
