1. PUBLIC WORKSHOP STATEWIDE DIESEL ENGINE IDLE REDUCTION STANDARD August 23, 2007 Department of Environmental Protection Division of Air Resource Management

2. Executive Order 07-127  Establishing Immediate Actions to Reduce Greenhouse Gas Emissions within Florida DEP to develop rules to achieve……… DEP to develop rules to achieve……… Adoption of a statewide diesel engine idle reduction standard.Adoption of a statewide diesel engine idle reduction standard.

3. Impacts of Idling  Wastes fuel Burns 1 gallon per hour while alternatives like auxiliary power units consume 10% to 20%Burns 1 gallon per hour while alternatives like auxiliary power units consume 10% to 20%  Increased emissions of greenhouse gases and other pollutants

4. Greenhouse Gas (GHG) Impacts  Department of Energy Based on nationwide numbers (500,000 long haul trucks in review data) Based on nationwide numbers (500,000 long haul trucks in review data) 1 billion gallons for overnight idling1 billion gallons for overnight idling 2 billion gallons for workday idling2 billion gallons for workday idling  EPA Estimates Emissions from overnight idling alone total 7.6 million tons of CO 2 Emissions from overnight idling alone total 7.6 million tons of CO 2  California Estimates In 2010, sleeper trucks idling emissions are In 2010, sleeper trucks idling emissions are estimated at 1 million tons of GHG emissions per year.

5. Executive Order Allows  Broad Range of Options Passenger cars and light trucks Passenger cars and light trucks Commercial buses Commercial buses Heavy trucks Heavy trucks Locomotives Locomotives Ships at Port Ships at Port

6. Common State Idle Reduction Requirements  Target vehicles producing greatest amount of emissions Commercial heavy duty vehicles typically over 10,000 lbs Commercial heavy duty vehicles typically over 10,000 lbs Delivery vehiclesDelivery vehicles BusesBuses Tractor TrailerTractor Trailer  Idle time 5 minutes Idle time is consistent with EPA’s Model State Idling Law Idle time is consistent with EPA’s Model State Idling Law  Provide Exemptions

7. Common Idling Exemptions for Heavy-Duty Vehicles  Certain buses  Tractors with sleeper berths in use  Vehicle queuing  Weather or mechanical/safety problems  Maintenance  Power takeoff operations  Emergency or Military operations  ADA requirements

8. California: Most Stringent Requirements  First state to restrict idling in sleeper berth trucks 14,000 lbs and over 14,000 lbs and over Provisions go into effect January 2008 Provisions go into effect January 2008 Subject to the 5 minute idle limit Subject to the 5 minute idle limit  New trucks sold in California required to include automatic engine shut down feature

9. Emerging Areas of Idling Concern  Locomotives Switchyards Switchyards Worker breaks Worker breaks Crew changes Crew changes  Ports Vessels Vessels Cargo handling equipment Cargo handling equipment Trucks and vehicles Trucks and vehicles Harbor Vessels Harbor Vessels Rail Rail

10. Idle Reduction Options  Operational practices  Technology and Infrastructure

11. Operational Changes  Turn engine off after a set time  Scheduling and logistics improvements to reduce idle times

12. Technology Options Identified By Other Idle Reduction Programs  Aux power units (APU).  Truck stop electrification Onboard power systems Onboard power systems Off board power systems Off board power systems  Integrated power systems in new vehicles (battery systems)  Fuel fired heaters  Thermal energy storage systems  Automatic engine shutdown system

13. Locomotive & Shipping Port Technology Locomotive & Shipping Port Technology  Locomotives Hybrid electric switchyard engines Hybrid electric switchyard engines Automatic engine shut down system Automatic engine shut down system  Shipping Ports Shore power infrastructure Shore power infrastructure New technologies (e.g., electric cranes, battery-electric vehicles) New technologies (e.g., electric cranes, battery-electric vehicles)

14. Conclusions  Heavy Duty Diesel Vehicles (HDDV) Primary focus of most state idle reduction strategies Primary focus of most state idle reduction strategies  Locomotives Not as many regulatory examples Not as many regulatory examples More uncertain technology More uncertain technology High potential for improvement High potential for improvement  Shipping Ports Most programs in developing phase Most programs in developing phase Complex to regulate Complex to regulate

15. Comments  Scope of regulation Identification of diesel engines suitable for inclusion Identification of diesel engines suitable for inclusion Identification of exemptions Identification of exemptions  Infrastructure needs  Costs Technology Technology Implementation Implementation  Emissions data  Avoid negative impacts on overall air quality
