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
