Diesel Emissions
2
Emissions Task Force

• Divided into 6 sub groups
• Locomotive Group
• Car Group
• Ventilation Group
• Fuel Group
• Emissions Testing Group
• Funding Group

3
Metra's Testing Timeline

• 3 Phases
• Phase 1 Rail cars
• Phase 2 Station Platforms
• Phase 3 Engineer locomotive cabs, cab cars, and
  shops

4
Phase 1 Rail Cars

• Three sampling sites per train, first two cars
  after engine and rear cab car
• Testing runs already completed on Rock Island,
  Burlington Northern, Milwaukee District, and
  Union Pacific as of this week.

5
Diesel Exhaust Components

• Particulate matter
• Polynuclear aromatic hydrocarbons
• Carbon (elemental and organic)
• Aldehydes
• Benzene
• Carbon monoxide
• Nitric Oxide
• Nitrogen Dioxide
• Sulfur Dioxide

6
Metra's Testing Protocol

• Direct read instruments
• Provides real time data collection
• Sampling for Total Particulate, PM 2.5, Carbon,
  Carbon Monoxide, Nitric Oxide, Nitrogen Dioxide,
  and Sulfur Dioxide
• Includes same aethalometer used in Tribune
  article

7
Metra's Testing Protocol

• Active sampling instruments
• Provides laboratory analytical results
• Sampling for Polynuclear Aromatic Hydrocarbons,
  Benzene Vapors and Carbon

8
Metra's Testing Protocol

• Metra Locomotive Tiers
• Unregulated
• Tier 0
• Tier 0
• Tier 1

9
Relevant Regulatory Agencies

• EPA Environmental Protection Agency
• Establishes National Ambient Air Quality
  Standards
• Establishes Locomotive Standards

10
Relevant Regulatory Agencies

• OSHA Occupational Safety and Health
  Administration
• Deals with occupational exposure and establishes
  permissible exposure limits for employees

11
Relevant Regulatory Agencies

• No exposure guidelines for elemental carbon or
  black soot have been established for the general
  public (Metra's ridership)

12
Metra In-House Committees

• All Groups have had a committee meeting
• Emissions Testing Group
• Established no regulatory agency has a threshold
  for carbon 2.5 or nano-particles and therefore
  has no level established
• Asking group to come up with recommendation
  based on a study or guideline

13
Metra In-House Committees

• Locomotive Group
• Exhaust after treatment (Doc)
• 25 particulate reduction on Tier 0, Tier 1, Tier
  0
• Engine changes to turbocharger and possible
  injectors

14
Metra In-House Committees

• Car Group
• Filters
• Air intake on cars
• Car pressurization
• Ventilation design of older cars for future
  changes during rehabilitation

15
Metra In-House Committees

• Ventilation Group
• Working with Amtrak to discuss contracts and
  agreements with adjacent building owners for
  maintenance and operation at CUS
• Procedures for shutting down equipment and using
  standby power at all locations

16
Metra In-House Committees

• Fuel Group
• Switching to Ultra Low Sulfur Diesel Fuel (ULSD)
  April 1, 2011
• Has industry proven reduction in particulate of
  8
• Fuel additives were discussed and not a
  verifiable reduction
• Alternate fuels
• Grants have recently been awarded to look at
  Bio-Diesel

17
Metra In-House Committees

• Funding Group
• Small allocation are only available which we
  will pursue
• Metras needs are significant to reduce these
  emissions and will require a large capital
  investment

18
Phase 2 Station Platforms

• Air sampling completed at Chicago Union Station
  in July 2010
• Sampling to be performed at Ogilvie
  Transportation Center and LaSalle Street Station
  in January 2011

19
Phase 3 Engineer Cab Cars

• Plans to test engineer locomotive cab and cab
  cars after station platforms
• Identify any engineer exposure during a work day
• Test our shops and layover facilities
