                                                             • SCR cleans up NOx in exhaust stream




   WHAT’S NEW ? - Trucks will need to carry DEF on board

                                                           • Vocational applications – daily refueling
• DEF Warning – where SCR sensor detects high                from a central location
  NOx levels
                                                              – DEF tank capacity must equal fuel capacity

• Engine Derate – if problem is not remedied               • Twice the range (miles or hours) – if there
  within 500 miles or 10 hours, reduce maximum
  engine torque by 25% (downshifting – fuel
                                                             is a constant DEF level indicator

• Severe Inducement – if problem is not remedied
  within 1,000 miles or 20 hours, 5 mph restriction
  after refueling, parking or restart.




       Misfueling Concerns                                 What is DEF?
• Inlet for DEF is smaller than diesel nozzles
                                                           • A urea-based solution
   – Prevent damage to SCR system

• Possible to put DEF in the diesel tank (DEF              • Urea is a common agricultural fertilizer that is
  dispenser nozzle or canister will be smaller than          solid at room temperature
  the diesel fuel tank inlet)
   – Unlikely due to the size differential between the     • DEF – ISO 22241
     diesel and urea nozzles
                                                              – 32.5% automotive grade urea
   – fuel/water separator would capture up to a quart or
     two of DEF to prevent engine damage                      – 67.5% deionized water


• There is a magnetic nozzle interlock solution            • DEF Quality and Purity are important
  mandated in some countries, but not in the                  – API Certification Program [http://www.apidef.org]

•    DEF is corrosive to aluminum and carbon steel

•    DEF is not classified as a hazardous material by DOT

          – DEF freezes below 12°F
          – DEF efficacy is not impacted by freezing                                      – Deionized water (mineral salts removed)
            and subsequent defrosting

    Hot Weather:
          – Store below 86°F                                                              – SCR / NOx sensors – you better get it right
          – Exposure to excessive heat for extended
            time will reduce shelf life
          – 90°F storage reduces shelf life to 6 months

A big deal for big rigs(and little ones too).
  To help consumers locate diesel exhaust fluid that meets diesel engine manufacturer requirements,
  API has established the Diesel Exhaust Fluid Certification Program, a voluntary program that certifies
  and monitors the quality of diesel exhaust fluid intended for use in SCR-equipped cars and trucks.
  Diesel exhaust fluid marketers that certify that they meet the performance requirements developed
  by diesel engine manufacturers may be licensed by API to display the API Diesel Exhaust Fluid
  Certification Mark. This mark identifies fluids meeting the performance requirements for proper
  SCR operation.

The consumption of DEF is expected to grow rapidly during the first few years after 2010. By
2012 it is estimated over 175 million gallons of DEF will be consumed in class 6-8 vehicles in
the US and Canada. At an estimated cost of $3/gallon that equates to over $525 million
dollars in DEF revenue.

                               DISPENSING DEF — FIRE CODE CONSIDERATIONS


I.   Terminology

     Approved. Acceptable to the authority having jurisdiction.

     Authority Having Jurisdiction. An organization, office, or individual responsible for enforcing the requirements of a code or standard, or for approving
     equipment, materials, an installation, or a procedure.

     NOTE: The phrase "authority having jurisdiction" is used in NFPA documents in a broad manner because jurisdictions and approval agencies vary, as
     do their responsibilities. Where public safety is primary, the authority having jurisdiction might be a federal, state, local, or other regional department or
     individual such as a fire chief; fire marshal; chief of a fire prevention bureau, labor department, or health department; building official; electrical
     inspector; or others having statutory authority. For insurance purposes, an insurance inspection department, rating bureau, or other insurance company
     representative might be the authority having jurisdiction. In many circumstances, the property owner or his or her designated agent assumes the role of
     the authority having jurisdiction; at government installations, the commanding officer or departmental official might be the authority having jurisdiction.

     Labeled. Equipment or materials to which has been attached a label, symbol, or other identifying mark of an organization that is acceptable to the
     authority having jurisdiction and concerned with product evaluation, that maintains periodic inspection of production of labeled equipment or materials,
     and by whose labeling the manufacturer indicates compliance with appropriate standards or performance in a specified manner.

     Listed. Equipment, materials, or services included in a list published by an organization that is acceptable to the authority having jurisdiction and
     concerned with evaluation of products or services, that maintains periodic inspection of production of listed equipment or materials or periodic evaluation
     of services, and whose listing states that either the equipment, material, or service meets appropriate designated standards or has been tested and found
     suitable for a specified purpose.

     NOTE: The means for identifying listed equipment may vary for each organization concerned with product evaluation; some organizations do not
     recognize equipment as listed unless it is also labeled. The authority having jurisdiction should utilize the system employed by the listing organization to
     identify a listed product.

     Code. A standard that is an extensive compilation of provisions covering broad subject matter or that is suitable for adoption into law independently of
     other codes and standards.

     NOTE: The decision whether to designate a standard as a “code” is based on such factors as the size and scope of the document, its intended use and
     form of adoption, and whether it contains substantial enforcement and administrative provisions.

     Standard. A document, the main text of which contains only mandatory provisions using the word “shall” to indicate requirements and which is in a
     form generally suitable for mandatory reference by another standard or code or for adoption into law. Nonmandatory provisions are located in an
     appendix or annex, footnote, or fine-print note and are not to be considered a part of the requirements of a standard.
II.    Applicable Documents – Scopes

       NFPA 30, Flammable and Combustible Liquids Code. This code applies to the storage, handling, and use of flammable and combustible liquids,
       including waste liquids, as defined and classified therein.

       NFPA 30A, Code for Motor Fuel Dispensing Facilities and Repair Garages. This code applies to motor fuel dispensing facilities; marine motor fuel
       dispensing facilities; and motor fuel dispensing facilities located inside buildings, at fleet vehicle motor fuel facilities, and at farms and isolated
       construction sites. This code also applies to motor vehicle repair garages. This code DOES NOT apply to any motor fuel dispensing facility where only
       gaseous fuels are stored and dispensed.

       NFPA 70®, National Electrical Code®. This Code covers the installation of electrical conductors, equipment, and raceways; signaling and
       communications conductors, equipment, and raceways; and optical fiber cables and raceways for the following:

       (1) Public and private premises, including buildings, structures, mobile homes, recreational vehicles, and floating buildings
       (2) Yards, lots, parking lots, carnivals, and industrial substations
       (3) Installations of conductors and equipment that connect to the supply of electricity
       (4) Installations used by the electric utility, such as office buildings, warehouses, garages, machine shops, and recreational buildings, that are not an
       integral part of a generating plant, substation, or control center.

       NFPA 400, Hazardous Materials Code. This Code applies to the storage, use, and handling of the following hazardous materials in all occupancies and
       facilities:
       (1) Corrosive solids and liquids
       (2) Flammable solids
       (3) Organic peroxide formulations
       (4) Oxidizer–solids and liquids
       (5) Pyrophoric solids and liquids
       (6) Toxic and highly toxic solids and liquids
       (7) Unstable (reactive) solids and liquids
       (8) Water-reactive solids and liquids
       (9)* Compressed gases and cryogenic fluids as included within the context of NFPA 55, Standard for the Storage, Use, and Handling of Compressed
       Gases and Cryogenic Fluids in Portable and Stationary Containers, Cylinders, and Tanks

       NFPA 704, Standard System for the Identification of the Hazards of Materials for Emergency Response. This standard addresses the health,
       flammability, instability, and related hazards that are presented by short-term, acute exposure to a material under conditions of fire, spill, or similar
       emergencies by providing a simple, readily recognized, and easily understood system of markings that gives a general idea of the hazards of a material
       and the severity of these hazards as they relate to emergency response.


III.   Typical Provisions of NFPA 30A that Require “Listed” Equipment or Components.
Aboveground Storage Tank. A horizontal or vertical tank that is listed and intended for fixed installation, without backfill, above or below grade and is
used within the scope of its approval or listing.
