8 Use Electric and Hybrid Construction Equipment CAPCOA’s Quantifying Greenhouse Gas Mitigation Measures23 report also proposes the use of electric and/or hybrid construction equipment as a way to mitigate DPM emissions. When construction equipment is powered by grid electricity rather than fossil fuel, direct emissions from fuel combustion are replaced with indirect emissions associated with the electricity used to power the equipment. Furthermore, when construction equipment is powered by hybrid‐electric drives, emissions from fuel combustion are also greatly reduced. Electric construction equipment is available commercially from companies such as Peterson Pacific Corporation,24 which specialize in the mechanical processing equipment like grinders and shredders. Construction equipment powered by hybrid‐electric drives is also commercially available from companies such as Caterpillar25. For example, Caterpillar reports that during an 8‐hour shift, its D7E hybrid dozer burns 19.5 percent fewer gallons of fuel than a conventional dozer while achieving a 10.3 percent increase in productivity. The D7E model burns 6.2 gallons per hour compared to a conventional dozer which burns 7.7 gallons per hour.26 Fuel usage and savings are dependent on the make and model of the construction equipment used. The Project Applicant should calculate project‐specific savings and provide manufacturer specifications indicating fuel burned per hour. Implement a Construction Vehicle Inventory Tracking System CAPCOA’s Quantifying Greenhouse Gas Mitigation Measures27 report recommends that the Project Applicant provide a detailed plan that discusses a construction vehicle inventory tracking system to ensure compliances with construction mitigation measures. The system should include strategies such as requiring engine run time meters on equipment, documenting the serial number, horsepower, manufacture age, fuel, etc. of all onsite equipment and daily logging of the operating hours of the equipment. Specifically, for each onroad construction vehicle, nonroad construction equipment, or generator, the contractor should submit to the developer’s representative a report prior to bringing said equipment on site that includes:28  Equipment type, equipment manufacturer, equipment serial number, engine manufacturer, engine model year, engine certification (Tier rating), horsepower, and engine serial number.  The type of emission control technology installed, serial number, make, model, manufacturer, and EPA/CARB verification number/level. 23http://www.capcoa.org/wp‐content/uploads/2010/11/CAPCOA‐Quantification‐Report‐9‐14‐Final.pdf 24 Peterson Electric Grinders Brochure, available at:http://www.petersoncorp.com/wp‐ content/uploads/peterson_electric_grinders1.pdf 25 Electric Power Products, available at:http://www.cat.com/en_US/products/new/power‐systems/electric‐power‐ generation.html 26http://www.capcoa.org/wp‐content/uploads/2010/11/CAPCOA‐Quantification‐Report‐9‐14‐Final.pdf 27http://www.capcoa.org/wp‐content/uploads/2010/11/CAPCOA‐Quantification‐Report‐9‐14‐Final.pdf 28 Diesel Emission Controls in Construction Projects, available at: http://www2.epa.gov/sites/production/files/2015‐09/documents/nedc‐model‐contract‐sepcification.pdf
