MISSOULA METROPOLITAN PLANNING ORGANIZATION 435 Ryman MISSOULA, MT 59802-4292 www.co.missoula.mt.us/transportation PHONE: (406) 258-4657 / FAX: (406) 258-3988 MISSOULA COUNTY Memorandum To: City Council Public Safety and Health Committee From: Ann Cundy, Senior Transportation Planner Date: July 6, 2010 Re: US EPA Clean Diesel Grant Program Background (from application): Downtown Missoula is directly adjacent to MRL’s railyard. This yard holds 8 switch engines and services an additional 38 engines per day. MRL has a total fleet of 119 diesel locomotives, seventy-one of these are in operation and 48 are in storage. Of the 71 locomotives in operation, 34 have no idle reduction technology. The remaining 37 are either Tier 1, Tier II, or have diesel auxiliary power units or electric plug-in technology. This project would retrofit the 34 pre-1972 engines with a new diesel powered APU. Pre-1972 engines are not required by Federal, State or local law to have idle reduction technology. This program is completely voluntary on MRL’s part and is fully support by local and state government entities and citizen groups. Due to Missoula’s cold climate, trains must idle while waiting in the railyard and or while waiting on the tracks leading into the yard. These are situated in a dense urban area (See map in Appendix The APUs are an EPA verified idle reduction technology which reduces the need to idle the main engine when temperatures fall below 40 degrees Fahrenheit, which occur year round in Montana. Use of the APUs in place of idling the main engines will result in an annual reduction of 5,423 tons of emissions and save 471,676 gallons of diesel annually. Total project reductions over the expected life of the APUs will be 55,390 tons of emissions and 4,816,950 gallons of diesel. Since the majority of MRL fleet spends 40% or more time idling, reducing idling will directly decrease diesel emissions and improve associated air quality while reducing diesel fuel use. Process and Timeline: MRL will purchase and install the 34 APU’s over the course of one calendar year as each of the locomotives travels through the central maintenance facility in Livingston, Montana. It takes between one and two weeks in install an APU. Missoula County will submit quarterly reports to EPA on the progress with installation and functionality of the APU’s, as well as reporting on the reduction in idling hours. From the reduction in idling hours, we can extrapolate the reduction in diesel fuel consumption and the emissions of the criteria and toxic air pollutants. ---PAGE BREAK--- Air Quality Benefits in Missoula: PRE: Current % POST: Estimated Average Annual Emissions Reduction with APU Annual Reduction in Emissions Annual Emissions with APU tons/year tons/year tons/year NOX 153.68 96.90 148.92 4.76 PM 3.78 96.70 3.65 0.13 HC 5.72 99.90 5.17 0.55 CO 15.50 94.10 14.14 1.36 CO2 5834.80 90.00 5251.00 583.8 Total 6013.48 5422.88 590.6 Ben Schmidt, Air Quality Specialist with the City-County Health Department, will attend the July 7, 2010 meeting to answer questions about how improvements to Missoula’s air quality can be measured as a result of the installation and use of the 34 APU’s.
