MPO: Baltimore Metropolitan Council
Description: 12 Bus Engine Upgrade - This project will fund 142 engine overhauls on the MTA bus fleet, including the installation of catalytic converters using an EPA certified engine rebuild kit. Each bus engine's rebuild is scheduled as needed or after 300,000 miles of service.

MTA has 794 buses available for service and the total vehicle miles in FFY 2001 were 21,774,843.

Southwestern Research and MTA data indicates that each gram per brake horsepower-hour (g/bhp-hr) is equal to 1.5 tons of PM per 100,000 bus-miles.

(3,894,241 overhaul bus miles / 100,000 miles * 1.5 tons = 58.41 tons of PM per g/bhp-hr)

Data provided by the Engelhard Automotive Emissions Systems indicates that depending on the age of a bus and engine type, the PM can be reduced between 0.46 and 0.05 g/bhp-hr. The average will vary around 0.255 g/bhp-hr of PM.

0.255 g/bhp-hr x 58.41 (conversion of g/bhp-hr to tons)= 14.9 tons of PM per year

Location: Medford, Oregon
MPO: Rogue Valley COG
Description: Install Filters on 9 Trash Collection Vehicles This project will fund the installation of advanced exhaust after-treatment controls on 9 diesel-powered trash collection trucks owned by Rogue Disposal and Recycling refuse collection company. The EPA's Retrofit Calculator was used to identify those 9 vehicles in the garbage hauling fleet's trucks that would be most cost effectively fitted with these devices. The filters will effectively reduce emissions of diesel particulate by over 80 percent, while also reducing CO and VOC emissions by 67 percent and 95 percent, respectively. Additional toxin reductions will include benzene, formaldehyde, and polycyclic aromatic hydrocarbons.

Location: Detroit, Michigan
MPO: Southeast Michigan Council of Governments
Description: Locomotive Diesel Engine Retrofits - This project will fund the repowering of six switcher (4-axle) locomotives at the CSXT Rougemere Rail Yard with ultra-clean Generator Set (GENSET) diesel locomotive engine technology. The repowered locomotives will operate within the CSXT Detroit rail yard for five years. Each existing locomotive is stripped from the deck up, removing the large, single diesel engine that provides power. The engine is replaced with three smaller, ultra-clean diesel generators, which are fitted onto the platform, along with new control, and operating equipment. The Southeast Michigan Council of Governments (SEMCOG) anticipates repowering three locomotives in 2007 and another three in 2008; this analysis only accounts for the three 2007 repowerings.

Emissions
Δ VOC - 9.96 kg/day METHODOLOGY/ASSUMPTIONS:
Δ NOx - 132.1 kg/day

Baseline NOx emissions are calculated using the USEPA emissions standard for a Tier 0 switch engine. Baseline PM and VOC emissions are conservatively calculated using the lower uncontrolled USEPA emissions factors of 0.44 g/bhp-hr PM and 1.01 g/bhp-hr VOC in lieu of the Tier 0 standards of 0.72 g/bhp-hr PM and 2.1 g/bhp-hr VOC. Conventional switcher fuel use is 60,000 gal/yr. According to USEPA, the Brake-Specific Fuel Consumption (BSFC) is 20.8 bhp-hr/gal. GENSET locomotive emissions factors are based on Tier 3 nonroad engine standards (grams/bhp-hr) since the locomotive is powered by these engines. NMHC has the same meaning as VOC and HC. The GENSET fuel use is 25% less than a conventional switcher (45,000 gal/yr). The Brake-Specific Fuel Consumption (BSFC) for a GENSET engine is reported as 19.5 bhp-hr/gal.

  • NOX Emissions (kg/yr) = BSFC * Fuel Used * Emissions Factor * 3 Locomotives
  • Baseline NOx = 20.8 * 60,000 * 14.0 * 3 = 52,416 kg/year
  • GENSET NOx = 19.5 * 45,000 * 2.85 * 3 = 7,503 kg/year
  • Daily reduction in NOx = (52,416 - 7,503) / 340 days per year = 132.1 kg/day

Calculation also assumes 86% reduction in ozone precursors and 76% reduction in PM.

Description: Advance Travel Center Electrification (IdleAire) - The City of Oak Grove hired IdleAire to install 50 ATE units at Pilot Travel Center #49, a site conveniently located off of I-24 at Exit 89, in Christian County, Kentucky. These IdleAire units provide heating and air conditioning, as well as a wide range of communication and entertainment options, directly into the cab of a parked truck. This allows a truck driver to completely shut down the truck's engine, eliminating the air pollution associated with idling. This such ATE project will save 182,500 gallons of diesel fuel annually, remove over 1,700 tons of emissions annually, and remove existing barriers to the quality of driver rest, such as noise, vibrations, and fumes.
