Presentation Transcript
emissions task force
Emissions Task Force
  • Divided into 6 sub groups
    • Locomotive Group
    • Car Group
    • Ventilation Group
    • Fuel Group
    • Emissions Testing Group
    • Funding Group
metra s testing timeline
Metra\'s Testing Timeline
  • 3 Phases
  • Phase 1 – Rail cars
  • Phase 2 – Station Platforms
  • Phase 3 – Engineer locomotive cabs, cab cars, and shops
phase 1 rail cars
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.
diesel exhaust components
Diesel Exhaust Components
  • Particulate matter
  • Polynuclear aromatic hydrocarbons
  • Carbon (elemental and organic)
  • Aldehydes
  • Benzene
  • Carbon monoxide
  • Nitric Oxide
  • Nitrogen Dioxide
  • Sulfur Dioxide
metra s testing protocol
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
metra s testing protocol1
Metra\'s Testing Protocol
  • Active sampling instruments
    • Provides laboratory analytical results
    • Sampling for Polynuclear Aromatic Hydrocarbons, Benzene Vapors and Carbon
metra s testing protocol2
Metra\'s Testing Protocol
  • Metra Locomotive Tiers
    • Unregulated
    • Tier 0
    • Tier 0+
    • Tier 1
relevant regulatory agencies
Relevant Regulatory Agencies
  • EPA – Environmental Protection Agency
    • Establishes National Ambient Air Quality Standards
    • Establishes Locomotive Standards
relevant regulatory agencies1
Relevant Regulatory Agencies
  • OSHA – Occupational Safety and Health Administration
    • Deals with occupational exposure and establishes permissible exposure limits for employees
relevant regulatory agencies2
Relevant Regulatory Agencies
  • No exposure guidelines for elemental carbon or black soot have been established for the general public (Metra\'s ridership)
metra in house committees
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
metra in house committees1
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
metra in house committees2
Metra In-House Committees
  • Car Group
    • Filters
    • Air intake on cars
    • Car pressurization
    • Ventilation design of older cars for future changes during rehabilitation
metra in house committees3
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
metra in house committees4
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
metra in house committees5
Metra In-House Committees
  • Funding Group
    • Small allocation are only available which we will pursue
    • Metra’s needs are significant to reduce these emissions and will require a large capital investment
phase 2 station platforms
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
phase 3 engineer cab cars
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
