Diesel emissions

Diesel Emissions


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
