Regulations Tutorial
Overview of Current Regulatory Environment
• Rationale for regulations– Concern over air quality and impact of increasing numbers of
automobiles on public health
– Legislation gives U.S. Environmental Protection Agency (EPA) authority to regulate emissions into the atmosphere
– Fuels regulations are designed to improve air emissions from “mobile sources” (vehicles)
• Background information – regulatory framework– Requires product registration for all gasoline, diesel and fuel
additives
– Applies to manufacturers (refiners), blenders and importers
– EPA requires testing of some fuels and additives
– EPA required certified detergent additives for gasoline
Current Regulations – U.S.
• Enforcement– Customer complaints and random sampling of fuels can result in
litigation and imposition of fines
– Fuel producer, blender, importer can be required to produce records showing compliance with the regulations
– If out of compliance, responsible party can be fined up to $32,500 per day for each violation found
Current Regulations – U.S.
• EPA and State Interface– States must file a “State Implementation Plan” (SIP) with the EPA
telling how they will meet Federal clean air standards for certain pollutants within a specified time
– EPA sets a standard for the state or certain geographical areas within it that must meet specific targets Example “Severe Non-Attainment” area means an area subject
to the most stringent regulations
– States can “opt” to meet more stringent standards than the EPA requires if they choose
Current Regulations – U.S.Federal vs. State
• Why states agree to Federal regulation– States that do not meet compliance targets for air quality by
designated target dates are not eligible for Federal highway funding
– Populations of large states like Texas would face significant costs to build and maintain roads without this money
Current Regulations – U.S.Penalties for Noncompliance
Current Regulations – U.S.
Gasoline
• 1973 – ban on lead– Initial regulations targeted elimination of TEL (tetraethyl lead)
– Complete ban - 1995
• Operations changes – round 1– Blend changes to replace octane loss
Arco (BP) introduces “EC-1” with MTBE in California Use of ethanol in U.S. PADDII (“Gasohol”)
– RVP not an issue until 1989
Current Regulations – U.S.Gasoline – Lead Leaves the Pool
• 1989 Regs – Summer Volatility Standards– Imposed to reduce ozone formation in summer
– Phase I – 1989 to 1991
– Phase II – 1992 and later
– Current ranges are 7.0 to 9.0 depending on the regulated area outside California
– California standards are more stringent
– Gasoline blended with ethanol can exceed these limits by 1.0 even though it reduces the benefit of lower RVP
• Operations changes – Increases in low RVP blending components
– Reduced ability to blend butane
Current Regulations – U.S.Gasoline – RVP Reductions
• Oxygenated fuels programs– Begun by states to reduce formation of carbon monoxide in winter
Original RFG was “EC-1” introduced in California by Arco (BP) in the late 1980’s to replace leaded gasoline; contained MTBE
– Resulted in the first reformulated gasoline (RFG) standards at the federal level in 1995 Required in areas considered “severe” non-attainment for ozone Other areas can “opt in”
• RFG Phase I and II – 1995 to 2000 and 2000 to 2005
– Established fuel performance standards
– Required 2% to 2.7% oxygenate by weight
– Initially allowed ethanol or MTBE to be used
Current Regulations – U.S.Gasoline – Oxygenates/RFG

Current Regulations – U.S.Gasoline – Pre and Post RFG
• Dramatic reduction in sulfur in total pool– From 1170 to 106 ppm in conventional by 2005– From 313 in “oxyfuel” to 71-81 in RFG by 2005
• RVP reductions– From as high as 15.9 in conventional to 8.3 (summer)– From 8.7 for “oxyfuel” to 6.9 for Phase II RFG
• Reduction in benzene– From as high as 5.18% to 1.21% in conventional and from 1.6%
to .66% in RFG
Current Regulations – U.S.Gasoline – Changes with RFG
• “Tier 2 and Gasoline Sulfur Program”– Required changes in vehicles for model year 2004 and later
– Required another “ratchet” downward on sulfur in motor gasoline
• Major changes in sulfur limits for gasoline and diesel– Per gallon cap of 80 ppm (gasoline)
– Average of 30 ppm (gasoline)
– Diesel regs discussed in next section
• “Phase in” period began January 2004– Special rules for small refiners to extend transition period
Current Regulations – U.S.Tier 2 – More Sulfur Reductions
• The “MSAT” Regulations– Establishes an Exhaust Toxics Standard for conventional gasoline
– Establishes a Total Toxics Standard for RFG
• Requires refiners to maintain at least their average 1998-2000 performance levels for 5 types of toxics considered probable human carcinogens– Benzene
– Formaldehyde
– Acetaldehyde
– 1-3 Butadiene
– POM
Current Regulations – U.S.Gasoline – Toxics
• Also known as the “anti backsliding” regulation– Performance in 2000 was better than what the current regulations
actually required at the time
– Set a baseline for future performance at the 1998-2000 level
– Producers had to file their baselines and demonstrate they were at those levels or better (further reduction from baseline) in the future
– Established a default baseline for refiners without a 1998-2000 history
Current Regulations – U.S.Gasoline – Toxics – MSAT 1
• Followed a review of toxics in fuels as of mid decade– Affects gasoline, passenger vehicles, and gas cans
– Applies to both conventional and reformulated gasoline
• Sets a new annual average benzene content limit of .62% nationwide
• New standard goes into effect 2011
Current Regulations – U.S.Gasoline Toxics – MSAT 2
• Other provisions of MSAT 2– Refiners/blenders can meet the standard by buying credits until
2012
– After July 1, 2012, actual volume ceiling of 1.3% is effective for all
• California is exempt; its standards are already lower
• Special compliance flexibility for approved small refiners
Current Regulations – U.S.Gasoline Toxics – MSAT 2
• Forecast impact– Refiners/blenders in Pacific NW, AK and Rockies, others with
higher than average benzene will have to make additional investments
– Refiners/blenders who reduce benzene early, can generate and trade “early credits” if using specific technologies approved by EPA
Current Regulations – U.S.Gasoline Toxics – MSAT 2 Impact
• Early credits– Early credits can be generated from 2007 through 2010
– 5 types of benzene control technologies qualify for early credit generation: Reformer feed treating (light naphtha splitting or isomerization) Reformate treating (benzene extraction or benzene saturation) Treating other streams not used as reformer feed (other naphtha) Treating benzene streams other than reformate Benzene alkylation
Current Regulations – U.S.Gasoline Toxics MSAT 2 – Credits
• 20 years after the Clean Air Act– Elimination of lead
– The rise and fall of MTBE as a gasoline blendstock
– Dramatic reductions in sulfur (from 1000+ ppm to virtually none today)
– Major reductions in RVP ceilings To meet summer ozone standards To accommodate mandated increases in ethanol blending
– Stringent caps on benzene
Summary Current Regulations – U.S.Gasoline
Current Regulations – U.S.
Diesel
• Diesel fuel quality– Has been regulated since 1993 with introduction of “LSD” (Low
Sulfur Diesel)
– Highway sulfur diesel program finalized in 2001
– Required transition from low sulfur diesel to ULSD (Ultra Low Sulfur Diesel) by 2006 for on road vehicles
– New sulfur limit for ULSD is 15 ppm
– Limit is measured at the point where the fuel is delivered to the consumer
– Refiners upstream in the distribution system have to deliver at less than 15 ppm
– “Non Road”, Locomotive, and Marine (NRLM) diesel sulfur content reduction targets are staged between 2007 and 2012

Diesel RegulationsSummary and Timeline
• Billions in hydrotreating investments– Needed to produce initial LSD (Low Sulfur Diesel) and remove
gasoline sulfur (RFG program) in mid 1990’s
– Significant investments since 2000 to accommodate Tier 2 sulfur reductions and ULSD (Ultra Low Sulfur Diesel) programs
– Some new refineries will treat whole crude stream vs. intermediates
• Investment in testing & instrumentation– ULSD standards require test methods able to detect very low
concentrations of sulfur
– Repeatability is important to document compliance with specs when shipments are transferred
– New lab equipment needed at terminals; increase in transmix volumes due to “trail back” of sulfur in batch systems
Impact of Diesel Rules to Date
• Dramatic reductions in allowable sulfur content beginning with low sulfur diesel in 1993
• Reduction in allowable sulfur in most engine fuels to 15 ppm by 2014
• Further restrictions on sulfur in residual fuels due to new limits in the marine markets (MARPOL VI standards)
• Requirements for blendstocks to accommodate mandated use of biofuels (Renewables standards)

The Rise of Renewable Fuels
Renewable Fuels
• A new type of regulation– Energy Independence and Security Act of 2007
Gives EPA the power to revise and implement regulations to “ensure that gasoline sold in the United States contains a minimum volume of renewable fuel.”
– Departs from air quality mission - this goal NOT based on air quality issues
– Designed to promote increased use of U.S. based renewable fuels
• Current regulations “RFS 1”– “Renewables” defined as produced from plant or animal products or
wastes
– Target total volume of renewables to be blended into gasoline From a minimum of 7.5 billion gallons by 2012 (489,000 BPD) to 36 billion gallons
(2.3 million BPD) by 2022 2012 target has been met; 2008 volume was 9 billion gallons Target post 2012 adjusted depending on gasoline demand – if gasoline demand
actually peaked in 2007 the target could potentially fall
– Refiners “obligated” to either blend the required volume or buy “RIN’s” (Renewable ID Numbers) to make up the difference
– Refiners must file reports demonstrating compliance on a corporate level
– Small refiners exempt through 2010
– Alaska and Hawaii exempt indefinitely
Renewable Fuels – “RFS 1”
• “RFS 1” impacts to date– Consumer resistance in some regions due to lowered mileage
– Unsufficient consideration given to total lifecycle emissions of renewable production
– High cost of RIN’s has changed the relationship between refiners and third party blenders
– Issues over difficulty with biodiesel “gelling” in cooler regions
– 2009 “standard” is 10.21% - this exceeds the warranty tolerance for many automobiles
Renewable Fuels – “RFS 1”
• “RFS 2” rules proposed early 2009
• Resets the minimum gallon target from 5.4 billion in 2008 to 9.0 billion (vs. previous target of 7.5 billion by 2012)
• Adds mandated renewables requirement for diesel (both on and off-road)
• Sets new, specific volume standards for:– Cellulosic biofuels
– Biomass based diesel
– Advanced biofuel
– Total Renewables

RFS 2 – Volume Targets 2008-2015New Targets for “Nonconventional” Biofuels
• Renewables producers must determine lifecycle GHG impact of their fuels
• Lifecycle includes production and transport of feedstock used in fuels production
• Renewables must demonstrate a specified reduction in lifecycle GHG as compared to a 2005 baseline for the diesel or gasoline displaced to qualify for the “quota” in the regulations
• Ethanol plants in operation before December 2007 are exempt from this requirement

On the HorizonMarine Bunker Fuels Changes
MARPOL VI
• Regulations developed by “MARPOL”– Discharge into the air and water from marine vessels in the open
seas subject to agreements made by and between members party to the International Convention for the Prevention of Pollution from Ships (MARPOL 73/78)
– All parties to this “convention” must agreed to be bound by Annexes I and II; others are optional
– Affects pollution liability insurance
– Violators subject to inspection and fines
Diesel RegulationsMarine Fuels
• MARPOL– International MARine POLlution Convention (document) created by
the United Nations in 1973
– Subscribers to the MARPOL rules are members of the International Marine Organization (IMO)
– IMO is a UN agency that oversees the shipping industry
– Has 167 international government members
Diesel RegulationsMarine Fuels – “MARPOL”
• Annexes I and II – applies to all subscribers– Set agreed limits on discharges of oil/oily waste
– Contains standards for double hull tankers
– Forbid discharges of chemicals dangerous to marine life
– Governs discharges of “noxious liquid substances” in Baltic and Black Seas
• Annexes III through VI – optional– Annex VI governs air pollution from ships at sea
Diesel Regulations Marine BunkersMARPOL VI
• Annex VI – air pollution controls– Covers emissions of SoX, NoX & VOC’s from marine vessels
– Applies to fixed and floating drilling rigs and vessels above 400 tons
– Provides for issuance of an International Air Pollution Prevention Certificate to vessels and rigs inspected and in compliance
– NoX controls on engines installed or overhauled after January 2000
– Limits of 4.5% sulfur in marine bunkers on the seas and 1.5% in designated SoX control areas
Diesel Regulations Marine BunkersMARPOL VI
• Limits already imposed on sulfur in many ports
• Baltic Sea and North Sea established as Sulfur Emission Control Areas (SECA’s) with 1.5% limits
• U.S. EPA recently imposed a 1.5% limit on marine fuels within 200 miles of U.S. coasts
Diesel Regulations Marine BunkersMARPOL VI – Issues to Date
• Pressure is mounting for a global reduction from 4.5% to 1.5% on all marine fuels
• Proposed reduction from 1.5% to .5% in the Baltic Sea and North Sea SECA’s
• Proposed outright ban on marine bunkers
• New regulations on particulates and GHG’s
Diesel Regulations Marine BunkersMARPOL VI – On the Horizon
• EU fuels standards already more stringent than U.S. on sulfur; fewer restrictions on RVP and aromatics
• Export refiners already comply with U.S. standards for components coming here due to certification and registration requirements
• Chinese standards following Europe – sulfur too high for export to U.S.
• Middle East exporters targeting Euro V specs
• Still have flexibility to market “non compliant” components outside these boundaries
• Latin, Central, South America are still relatively “unregulated” markets
• All consuming markets interested in renewables
Asia, Europe, OtherCurrent Regulations - Summary
Summary and Outlook“What Can We Make?”
Scenario for the Future
• Continued pressure to remove sulfur from transportation fuels– “Nowhere to run, nowhere to hide” in fuels pool– Coke, asphalt last refuge for sulfur– Need for low sulfur kerosene in biodiesel blends
• Increased octane giveaway potential due to need for low RVP “BOB’s” (blendstocks for oxygenate blending) to accommodate increased ethanol use
• Replacing energy lost from increased use of ethanol• Outcome of “debate” over automobile warranties as ethanol
content increases
Facing the Future – Issues
• Low sulfur fuels
• Low RVP blendstocks for oxygenate blending
• Asphalt (considered a CO2 reduction since it’s not transformed in refining)
• Heating oil (higher sulfur still allowed for now)
• Low sulfur distillate
Overall OutlookWhat Can We Make?
• Outcome of GHG regulations for motor fuels – ongoing status of the Sept 2009 proposal for carbon emissions limits
• Whether EPA will continue to require increasing volumes of renewables regardless of overall gasoline/diesel market growth
• Pushback from consumers and car makers on requirements for higher ethanol volumes above warranted levels
• Adoption of programs to increase use of E85 in regions with high ethanol production
Overall OutlookWhat to Watch
