School Bus Program- Yr. 1

• Initial Partnership

• EPA ARC Diesel Committee
• Joint letter (DEP DOE) to Superintendents
• Invitation to MAPT Conference
• MAPT Position Policy Statement Ratified
• TDs workshop on health impacts
• DEP used social marketing to change idling
  behavior

Doing My Share...Campaign

• Used Social Marketing Strategies

Research- Identified effective strategies,
identified barriers conducted baseline survey of
attitudes and behaviors of TDs Getting
Commitment - Asked TDs and drivers to commit to
no-idling for healthier air - provided pledge
cards Establishing NORMS - Spotlighted on DEPs
Honor Roll school districts that implemented a
no-idling guideline Prompts/Reminders of Desired
Behavior - Provided magnets, key chains, tip
cards and pledge cards Evaluate Results - Post
survey results and celebrate successes in DEP

School Bus Program - Yr. 2

• Promoted additional strategies
• for reducing emissions

• Relocate parking lots/loading zones
• Shorten route length (purchase software)
• Place no-idling signs in schoolyard
• Increased engine maintenance
• Rewire safety lights
• Retrofit buses with emission controls
• Use ultra-low sulfur diesel or alternative fuels
• Install Webasto-type heaters
• Replace bus fleet with cleaner engines

Clean School Bus USA

• Maine Applies for Grant

• Purpose to demonstrate DOC technology on most
  commonly used engines in Maine fleet,
• Applied for DOCs most cost effective retrofit
  technology for PM reduction,
• Unique collaboration with DOE, DEP, MAPT, ARC,
• DEP invites Honor Roll districts to participate
  - statewide application.

Lessons Learned

• Certain engines already equipped with DOCs
  (Cummins and CAT, 2004 C-7 engines).
• Certain engines have defeat devices which turn
  off emission controls. (CAT and Cummins built
  1993-1998.)
• Wide geographic area discouraged vendors from
  applying.
• Database template needed to facilitate fleet
  data collection.
• More cost effective to train mechanics to do
  installation.
• Identified districts with central fueling depots
  that could use fuel borne catalysts in the
  retrofit demonstration project.

11
Buses Ineligible for Retrofit

• Some Caterpillar engines are outfitted with DOCs
  as OEM

12
Retrofit Demonstration

• Surveys conducted by grant partner, Asthma
  Regional Council

• Conduct baseline survey to identify potential
  barriers/issues of concern such as exhaust back
  pressure, warranty, durability, replacement
  costs, and fuel economy.
• Record data during installation and first year
  of operation to address barriers, share results
  with New England States.
• Demonstrate feasibility of the technology for
  school bus application for regional acceptance
  and implementation.
• Goal to encourage additional school districts
  to purchase DOCs in year two of the contract at
  this special pricing.

13
Request for Proposals

• DEP contract stipulations

• Vendor provides equipment and mechanic training
  or installation, direct to school districts.
• Mechanic installation training will be provided
  at the annual MAPT Conference.
• Contractors will conduct workshop at MAPT annual
  conference demonstrating retrofit technology to
  conferees.
• Contract to be in effect for two years and
  available at this purchase price to all public
  and private schools, state agencies, colleges and
  universities.

DOC Muffler plus Spiracle Crankcase Filter
Cost-Effective Solution
Spiracle Installed on School Bus

15
Contract Award

• Contract selection based on
  greatest reduction of PM emissions per
  dollar spent.
• Primary Award- Donaldson Corp. for DOC and
  Spiracle crankcase filter system which will
  reduce crankcase and tailpipe emissions by 40.
  (without ULSD).
• Secondary Award - Clean Diesel Technologies
  Platinum Plus Purifier Three school districts
  will conduct pilot program using FBC/DOC to
  demonstrate potential 7 fuel savings and
  reduction in elemental carbon.
