Rouse Ave. (City Commission Room) A. Call to Order B. Changes to the Agenda C. Approval of Minutes D. Public Comment – Please state your name and address in an audible tone of voice for the record. This is the time for individuals to comment on matters falling within the purview of the Working Group. Please limit your comments to three minutes. E. Review Annual Outreach Plan a. Prioritize outstanding items b. Timeline F. Upcoming Outreach a. PAC Presentations 1. Feb 15 @ 6:00pm, Hyalite Elementary Movie Night 2. Mar 4 @ 6:00pm, Irving Elementary 3. Mar 28, time TBD, Morning Star Elementary b. Driver’s Education Classes G. Bozeman Propane Buses a. DEQ Analysis H. FYI/Discussion a. Next meeting March 14 b. Quick tour: bozemanclimatepartners.net c. Upcoming events: DEQ Innovations in Energy Efficiency Workshop-Feb 16, Chasing Ice Screening-Mar 7, Gallatin Earth Celebration in April 2012 Idle Free Bozeman Outreach Plan Revised 11/8/12 With children back in school and winter rapidly approaching, fall is a good time of year to promote the Idle Free Bozeman message. The following strategies will be undertaken each year to communicate with the public: 1) Radio Public Service Announcements a. Emily Dickinson 4th Graders willing to record a 30-second message b. Monitor PSA play time to determine if paid radio ads are necessary. If so, i. Write a series of ads covering a few topics related to idling (health/fossil fuels/vehicle maintenance) 2) Flier Distribution a. Offer fliers in public locations (City Hall, Pro Building, Library, County Licensing, Federal Building) b. Special events (Earth Week, Catapalooza, downtown events) c. Businesses/Organizations (Coffee shops, restaurants, Chamber of Commerce) d. Schools (offer to BSD, Montessori Schools) e. Offer to County for Driver’s Registration Packet & Driver’s Education Courses f. Neighborhood Associations 3) School newsletter idling message under transportation section 4) Article in BoZone, Editorial in Chronicle, Local’s Guide (Bridger Bowl) 5) Public Service Announcement for City Commission & Channel 20 6) Post Idle Free information on Bozeman Climate Partners’ website/FB page 7) Short Idle Free presentations for other groups (Board of Health, Neighborhood Associations, MSU Sustainability Advisory Council, Bicycle Advisory Board, Green Drinks) 8) 2012 Special Project: a. First Security Bank Window Display b. Signal Box Art Wrap Outreach Possibilities for the Future 1) Partner with businesses and post Idle Free signs in business parking lots. We would design attractive Bozeman-specific signs and let commission pick final design. 2) Air quality, lichens as bio-monitors, and art: something similar to the “invisible connectedness of things” project which is in progress in Boulder, CO and Los Angeles 3) Snow stamps: create a simple, clever icon about idling that could be made into a snow stamp. Stamp could be deployed throughout town, at MSU, and Bridger Bowl after fresh snow. 4) More printed media: key chains, bumper stickers, coffee mugs February 8, 2013 Mike Waterman, Business Manager Vance Ruff, Transportation Director Bozeman School District RE: Bozeman Diesel Bus replacement with propane Dear Mike and Vance: I have used the U.S. EPA diesel emissions quantifier (EPA-deq) to estimate the pollutant reduction from your upcoming fleet replacement to propane. The EPA-deq uses the latest MOVES mobile source emissions model. The software does not estimate for a complete vehicle replacement, but rather an engine replacement/repower or fuel replacement for the model year bus being addressed. The output would be one that uses the 2003/4 model year bus chassis, and replaces engine and fuel system—not the optimum for reductions, and not as long a life as a full replacement (depending on the remaining life of the chassis). As a result, the estimate of emissions reduced is lower than what would be observed in the field. Also, the EPA-deq has no method to consider a “no-idle” policy for the base case, but an idle reduction method was added for the replacement vehicles. I used the mileage and fuel estimates provided by Vance Ruff on February 7, 2013 including: A total annual mileage for the 40-buses of 431,630 miles (using 181 days because of other repairs and travel), A fleet average fuel consumption of 6 miles per gallon, that produced An estimated fleet fuel consumption of 71,940 gallons a year. The EPA-deq estimates the reduction of each pollutant annually. Together, this represents an estimated 315.4722 tons of pollution reduced annually by the replacements, with a lifetime reduction total of 5,994 tons of pollution (if kept in service in the Bozeman area). I did not have any costs, so was unable to produce any of the “cost effectiveness” numbers. Effectively, the change from diesel to propane reduces: Oxides of nitrogen (NOx) by 79%, Unburned hydrocarbons (HC) by 50 percent, Carbon dioxide (CO2) emissions by 39%, and Fine particulate matter (PM-2.5) by 111%. The EPA-deq model can estimate a reduction greater than 100-percent of the baseline fleet because newer vehicles have a lower emissions amount and (usually) a better thermal and fuel efficiency (same power, less fuel). For example the EPA’s 2007 emissions levels are about 65- percent of those listed for 2004-vehicles. EPA measured (in the field with real-time data) emissions showing that the actual in-field emissions for 2007-era buses emit less than 90-percent of the 2004 emissions buses. This data and other data are reflected in the modeling. Another potentially confusing term is “diesel equivalent” gallons. These are not actual gallons of diesel reduced but a diesel equivalent based on the amount of carbon dioxide reduced for each fuel technology. For example, summer diesel fuel contains 138,800 Btus per gallon, and propane contains 91,500 Btus per gallon. A straight energy equivalent would show that a gallon of propane would be 0.659 diesel gallon equivalents. Winter diesel equivalents might be a better fit as it has about 10-percent less Btus and this is the fuel used by the buses for at least 4 months of the school year. , The EPA-deq uses the amount of carbon dioxide produced by the fuels. Since these are not the equal, the EPA-deq provides those amounts as “diesel gallon equivalents.” I have seen these reductions go beyond 100-percent of the baseline, but not in this case. I also provided the “First-year health benefits costs” to Gallatin County. This is based on the reduction of fine particulate (PM-2.5) matter alone, and is estimated at $15,000. EPA has a 32-page online booklet explanation of this and how it is calculated. The “short” version is that the amount represents the dollar amount of reduced medical costs for the first year due to the reduction of the fine diesel particulate. It is based on the county’s particulate-related respiratory health costs and past (EPA) project data. Below is a condensed version of the EPA-deq output.
