€ t Ms. Kuhl Page.5 PA-0600037(GP)8 PA-0600552(ZR) Limit the hours of operation of heavy duty equipment and/or the amount of equipment in use Replace fossil-fueled equipment with electrically driven equivalents (provided they are not run via.a portable generator set) Require that all diesel engines be shut off when, not in use to reduce emissions from idling Curtail construction during periods of high ambient pollutant concentrations; this may include ceasing of construction activity during the peak-hour of vehicular traffic on adjacent roadways, and "Spare the Air Days" declared by the District. Implement activity management (e.g. rescheduling activities to reduce short-term impacts) 11 During the smog season (May through.,October), lengthen the construction period to minimize the number of vehicles and equipment operating at the same time. Off road trucks should be equipped witl4 on-road engines when possible. Minimize obstruction of traffic on adjacent roadways. . The District encourages the applicant ari d fleet operators using the facility to take advantage of the District's Heavy-Duty E G gine program to reduce project emissions. The Heavy Duty program provides incentives for the replacement of older diesel engines with new, cleaner, fuel-efficient diesel engines. The program also provides incentives for the re-power of older, heavy-duty trucks with cleaner diesel engines or alternative fuel engines. New alternative fuel heavy-duty trucks also qualify. For more information regarding this program contact the District at (559) 230.5858 or visit our �h website at www.valle aEr.or /trans ortation/heav dut idx.htm. IN Construction equipment may be powered by diesel engines fueled by Ultra Low Sulfur Diesel (ULSD) or alternative diesel fuel blends. The California Air Resources Board (CARB) has certified specific alternative diesel fuel blends for NOx and/or PM emission reductions. Information on alternative diesel fuel blends can be found on CARB's website at www.arb.ca.qov/fuels/diesel/altdiesel/altdiesel.htm. Alternative- s fueled equipment may use CompressedE Natural Gas (CNG), Liquid Propane Gas (LPG), electricity, or other designated alternative fuels to achieve greater emission reductions than current diesel equipment.-Il For more information on any of the fuels or technologies above, please contact Mr. Chris Acree, Senior Air Quality Specialist, at (559) 230-5829: . 1 Construction equipment may be used that meets the current off-road engine emission 'h standards. Equipment with uncontrolled engines may be repowered with an emissionized engine that meets current standards. Tier 1, Tier II, and Tier III engines have significantly less NOx and PM emissions compared to uncontrolled engines. To find engines certified b CARB, see www,arb.ca. ov/ms ro /offroad/cerUcert. h . 9 Y �p ag p Construction equipment may also be retrofit with exhaust after-treatment devices that reduce NOx, ROG, and/or PM. A list of retrofit devices can be found on CARB's Diesel Emission Control Srategies we page, see www.arb.ca.gov/diesel/verdev/ verifiedtechnoloaies/vt.htm.
