<br />7 <br /> <br /> All diesel vehicles, construction equipment, and generators on site shall be fueled with ultra‐low <br />sulfur diesel fuel (ULSD) or a biodiesel blend17 approved by the original engine manufacturer <br />with sulfur content of 15 parts per million (ppm) or less. <br /> <br />Repower or Replace Older Construction Equipment Engines <br />The NEDC recognizes that availability of equipment that meets the EPA’s newer standards is limited.18 <br />Due to this limitation, the NEDC proposes actions that can be taken to reduce emissions from existing <br />equipment in the Best Practices for Clean Diesel Construction report.19 These actions include but are not <br />limited to: <br /> <br /> <br /> Replacement of older equipment with equipment meeting the latest emission standards. <br />Engine replacement can include substituting a cleaner highway engine for a nonroad engine. Diesel <br />equipment may also be replaced with other technologies or fuels. Examples include hybrid switcher <br />locomotives, electric cranes, LNG, CNG, LPG or propane yard tractors, forklifts or loaders. <br />Replacements using natural gas may require changes to fueling infrastructure.20 Replacements often <br />require some re‐engineering work due to differences in size and configuration. Typically, there are <br />benefits in fuel efficiency, reliability, warranty, and maintenance costs.21 <br /> <br />Install Retrofit Devices on Existing Construction Equipment <br />PM emissions from alternatively‐fueled construction equipment can be further reduced by installing <br />retrofit devices on existing and/or new equipment. The most common retrofit technologies are retrofit <br />devices for engine exhaust after‐treatment. These devices are installed in the exhaust system to reduce <br />emissions and should not impact engine or vehicle operation. 22 It should be noted that actual emissions <br />reductions and costs will depend on specific manufacturers, technologies and applications. Should the <br />Applicant be unable to obtain Tier 4 Interim or Tier 4 Final off‐road equipment engines for all pieces of <br />equipment with 50 hp or greater, the Applicant should consider use of engines that meet Tier 3 off‐road <br />emission standards and engines that are retrofitted with an ARB Level 2 or Level 3 Verified Diesel <br />Emissions Control Strategy (VDECS). <br /> <br /> <br />17 Biodiesel lends are only to be used in conjunction with the technologies which have been verified for use with <br />biodiesel blends and are subject to the following requirements: <br />http://www.arb.ca.gov/diesel/verdev/reg/biodieselcompliance.pdf <br />18http://northeastdiesel.org/pdf/BestPractices4CleanDieselConstructionAug2012.pdf <br />19http://northeastdiesel.org/pdf/BestPractices4CleanDieselConstructionAug2012.pdf <br />20 Alternative Fuel Conversion, EPA, available at: https://www.epa.gov/greenvehicles/alternative‐vehicle‐fuels <br />21 Cleaner Fuels, EPA, available at: https://www.epa.gov/verified‐diesel‐tech/verified‐technologies‐list‐clean‐diesel <br />22 Retrofit Technologies, EPA, available at: https://www.epa.gov/sites/production/files/2016‐ <br />03/documents/420f10027.pdf
