Diesel Emissions
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
3 Phases Phase 1 – Rail cars Phase 2 – Station Platforms Phase 3 – Engineer locomotive cabs, cab
cars, and shops
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
Particulate matter Polynuclear aromatic hydrocarbons Carbon (elemental and organic) Aldehydes Benzene Carbon monoxide Nitric Oxide Nitrogen Dioxide Sulfur Dioxide
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 Protocol
Active sampling instruments Provides laboratory analytical results Sampling for Polynuclear Aromatic
Hydrocarbons, Benzene Vapors and Carbon
Metra's Testing Protocol
Metra Locomotive Tiers Unregulated Tier 0 Tier 0+ Tier 1
Relevant Regulatory Agencies
EPA – Environmental Protection Agency Establishes National Ambient Air Quality
Standards Establishes Locomotive Standards
Relevant Regulatory Agencies
OSHA – Occupational Safety and Health Administration Deals with occupational exposure and
establishes permissible exposure limits for employees
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
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 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 Committees
Car Group Filters Air intake on cars Car pressurization Ventilation design of older cars for future
changes during rehabilitation
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 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 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
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
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
