1Clean Diesel Construction Requirements of the Port Authority of NY & NJ Dorian Bailey, Supervisor Chemical/Environmental Testing Engineering Department
2Rebuilding of the World Trade Center Environmental Performance Commitments“EPC” RequirementsSubmit a Diesel Engine Emission Mitigation PlanFollow Diesel Engine Anti-Idling PolicyUse Ultra Low Sulfur Diesel (ULSD) FuelMeet or Surpass Diesel Construction Equipment Age Requirements (Tier 2)Install Best Available Technology on > 50 HP
3New York City Local Law 77 “LL77” Requirements Use Ultra Low Sulfur Diesel (ULSD) FuelConsider nitrogen oxides and particulate matter strategiesInstall Best Available Technology on > 50 HPCategory I – retrofit tailpipe devices with the highest reductions in pollutantsCategory 2 – retrofit tailpipe devices with the lower reductions in pollutantsCategory 3 – Other fuel-change based emission reductions
5Agency Wide Clean Diesel Specifications Clean Diesel Specification Phase in PeriodAwarded in 2009 with total construction costs of $10 million or greater;Awarded in 2010 with total construction costs of $5 million of greater;Awarded in 2011 with total construction costs of $1.5 million of greater;All contracts awarded in 2012 or later
6Agency Wide Clean Diesel Specifications Applicability: All land based and barge mounted diesel powered construction equipment (Specifically excludes marine)Site Implementation: Immediate, i.e., all equipment must arrive on site meeting requirementsContract Book Location:Division 1: Diesel Fuel
7Submittal Requirements Excel format preferred initially and for updated inventoriesOnsite/off site datesMake, manufacturer, model, and serial numbers for: (1) engine (2) equipment and (3) retrofitEquipmentEngineRetrofitAnticipated function, days and hoursModel year, Tier Rating, HPInstallation datesDuration of use on projectFuel consumption per shiftPrior waivers or BAT determinations
8Diesel Engine Anti-Idling Policy The idling time of Non-Road and On-Road Vehicles shall be limited to three (3) consecutive minutes except as follows:On-Road Vehicle is forced to remain motionless because of traffic conditions or mechanical difficulties over which the operator has no controlWhen it is necessary to operate defrosting, heating, cooling or auxiliary equipment. Exempts cranes and concrete mixers when necessary.To bring the vehicle to the manufacturer’s recommended operating temperature.When the outdoor ambient temperature is below 20°.When the vehicle is being actively worked on for repairs or maintenance and idling is needed to effectuate repairs.
9ULSD and Other FuelsULSD (15 ppm) is required, which has been nationally available at on-road pumps since 2006Biodiesel, emuslfied diesel, oxy-diesel and fuel borne-catalysts alone will not meet PA BAT approval
10Newer Engines (Tier Levels) Agency wide specification mandates Tier 1 enginesEPC driven specifications for Lower Manhattan rebuilding requires Tier 2 enginesPA may move to a Tier 2 minimum standard after full implementationPreliminary EIS modeling for the Goethals Bridge Replacement Project shows a possible need for Tier 2 Engines with BAT
11Best Available Technology (BAT) All equipment > 50 HP must be retrofitted with emission control devices, such as:Diesel Oxidation Catalysts (DOC)Flow Through Filters (FTF)Diesel Particulate Filters (DPF)
12Diesel Oxidation Catalyst Smallest PM reductions (20 – 33%)Waivers required for use on equipment >75 HPEasiest, cheapest installationNo backpressure or maintenance issuesFigure 1:
13Flow Through Filters (FTF) More efficient PM removal than DOC (~50%)Waivers required for use on >75 HPCatalyzed mesh or torturous path filtersSome cleaning/maintenancePassive regeneration temperature requirementsSource:
14Diesel Particulate Filter BAT “Gold Standard” for PM• PM Removal Efficiencies (>90%)Active or passive filter media regenerationActive regeneration must be considered for higher HP applications with low exhaust tempsFigure 2:
15Retrofit Verification Programs PA Accepts Verification From:CARBEPAVERT/BUWAL
16Compliance is field verified! BAT SummaryGeneral PM Removal %:DPF > FTF > DOCFor HP, FTF or DOC is acceptable. No waiver requiredDevices should be verified by CARB or EPACompliance is field verified!
17Waivers Active regeneration must be considered Economic analysis of retrofit cost to equipment valueReciprocity (3 years for BAT)a. Safety/visibilityb. Void the engine warrantyc. Other mechanical reasonsd. Can’t upgrade Tier 0 to 1Cost: 30 percent of the fair market value of the construction equipmentEngineer’s discretion
18Questions?At the Port Authority, we are committed to a greener tomorrow.Thank you!
