The Philadelphia Diesel Difference:

A Partnership for Cleaner Air.

Air management services
Air Management Services

  • Source Registration

  • Compliance inspections

  • Enforcement

  • Emissions Inventory

  • Air Monitoring Network

  • Asbestos Control

  • Compliant Response

  • Implosions

  • Noise and vibration complaints

  • Outreach and Education

Problem in philadelphia
Problem in Philadelphia

  • Philadelphia ranked 5th worst in the nation for greatest public health risk associated with air toxics.

  • Estimated 3,085 cancers caused by diesel particulate.

  • Diesel exhaust responsible for 260 premature deaths a year in the Philadelphia area

  • Diesel vehicles comprise only 7.5% of the vehicle miles traveled in PA yet contribute 48% of the summertime NOX and 65% of fine particulate matter derived from highway vehicles .

National ambient air quality standards
National Ambient Air Quality Standards

  • Six criteria pollutants measured, based on health standards.

  • Pollutant Primary Stds. Averaging Times Secondary Stds.

  • CO 9 ppm (10 mg/m3) 8-hour None 35 ppm (40 mg/m3) 1-hour None

  • Lead 1.5 µg/m3 Quarterly Average Same as Primary

  • NO2 0.053 ppm (100 µg/m3) Annual Same as Primary

  • PM10 50 µg/m3 AnnualSame as Primary 150 ug/m3 24-hour

  • PM2.5 15 µg/m3 Annual Same as Primary 65 ug/m3 24-hour

  • Ozone 0.08 ppm 8-hour Same as Primary 0.12 ppm 1-hour Same as Primary

  • SOx 0.03 ppm Annual 0.14 ppm 24-hour 3-hour 0.5 ppm (1300 ug/m3)

  • Attainment status designates whether or not a health standard has been achieved.

Air quality impact for philadelphia
Air Quality Impact for Philadelphia

  • Diesel particulate (soot)

    • Likely to be in non-attainment for PM 2.5, of which a significant portion is PMdiesel.

  • Smog

    • Non-attainment for 1-hour ozone standard.

    • Non-attainment for 8-hour ozone standard.

  • Air Toxics

    • Mobile sources most significant.

Health effects of diesel exhaust
Health Effects of Diesel Exhaust

  • Chronic respiratory diseases.

  • Bronchitis.

  • Asthma.

  • Known carcinogen.

  • Children adversely affected.

Clean diesel technologies
Clean Diesel Technologies

  • Menu of options

    • Hardware

      • Particulate traps/filters

      • Oxidation catalysts

    • Clean Fuels

      • Ultra low sulfur diesel fuel

      • Emulsified Diesel Fuel

      • Bio-diesel

    • Idling Reduction Technology

    • Combination of the above

  • EPA and CARB Verified Technologies

Future of diesel marketplace
Future of Diesel Marketplace

  • Mid-2006: Ultra low sulfur diesel is required for all on-road diesel vehicles.

    • Sulfur content of diesel #2 reduced from 500 ppm to 15 ppm.

    • 97% reduction in sulfur content.

  • 2007: Original equipment manufacturers produce engines with cleaner exhaust systems.

Societal costs
Societal Costs

  • Premature death.

  • Asthma related emergency room visits.

  • Hospitalizations.

  • Heart attacks.

  • Lost work days.

  • Lost productivity.

  • Decreased quality of life.


  • Diesel engines have a 20-35 year lifespan.

  • Existing diesel engines require retrofits to bring them up to newer standards.

  • Retrofits can cost up to more than $6,000 per vehicle.

  • ULSD not mandatory until 2006.
