Rebuilding of the World Trade Center

1) Submit a Diesel Engine Emission Mitigation Plan

2) Follow Diesel Engine Anti-Idling Policy

3) Use Ultra Low Sulfur Diesel (ULSD) Fuel

4) Meet or Surpass Diesel Construction Equipment Age Requirements (Tier 2)

5) Install Best Available Technology on > 50 HP

Commitments

“EPC” Requirements

New York City Local Law 77

“LL77” Requirements

1)Use Ultra Low Sulfur Diesel (ULSD) Fuel

2)Consider nitrogen oxides and particulate matter strategies

3) Install Best Available Technology on > 50 HP

• Category I – retrofit tailpipe devices with the highest reductions in pollutants

• Category 2 – retrofit tailpipe devices with the lower reductions in pollutants

• Category 3 – Other fuel-change based emission reductions

Agency Wide Clean Diesel Specifications

• Idle Restrictions

• ULSD

• Newer Engines

• BAT

Core Requirements

Agency Wide Clean Diesel Specifications

• Awarded 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

Agency 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 requirements

Contract Book Location:

Division 1: Diesel Fuel

Submittal Requirements• Excel format preferred initially and for updated

inventories

• Onsite/off site dates

• Make, manufacturer, model, and serial numbers for: (1) engine (2) equipment and (3) retrofit

Prior waivers or BAT determinations

Diesel Engine Anti-Idling PolicyThe 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 control

• When 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.

ULSD and Other Fuels

• ULSD (15 ppm) is required, which has been nationally available at on-road pumps since 2006

• Biodiesel, emuslfied diesel, oxy-diesel and fuel borne-catalysts alone will not meet PA BAT approval

Newer Engines (Tier Levels)

Preliminary EIS modeling for the Goethals Bridge

Replacement Project shows a possible need for Tier 2

Engines with BAT

• Agency wide specification mandates Tier 1 engines

• EPC driven specifications for Lower Manhattan rebuilding requires Tier 2 engines

• PA may move to a Tier 2 minimum standard after full implementation

Best Available Technology (BAT)

Diesel Oxidation Catalysts (DOC)

Flow Through Filters (FTF)

Diesel Particulate Filters (DPF)

All equipment > 50 HP must be retrofitted with emission control devices, such as:

Diesel Oxidation Catalyst

• Smallest PM reductions (20 – 33%)

• Waivers required for use on equipment >75 HP

• Easiest, cheapest installation

• No backpressure or maintenance issues

Figure 1: http://www.meca.org/galleries/defaultimage/diesel_oxidation_catalyst.gif

Flow Through Filters (FTF)

• More efficient PM removal than DOC (~50%)

• Waivers required for use on >75 HP

• Catalyzed mesh or torturous path filters

• Some cleaning/maintenance

• Passive regeneration temperature requirements

Diesel Particulate Filter

• BAT “Gold Standard” for PM

• PM Removal Efficiencies (>90%)

• Active or passive filter media regeneration

Figure 2: http://www.meca.org/galleries/default-image/diesel_particulate_filter.gif

• Active regeneration must be considered for higher HP applications with low exhaust temps

Retrofit Verification Programs

http://www.epa.gov/oms/retrofit/verif-list.htm

http://www.bafu.admin.ch/publikationen/publikation/01010/index.html?lang=en

PA Accepts Verification From:

1) CARB

2) EPA

3) VERT/BUWAL

BAT Summary

• General PM Removal %:

DPF > FTF > DOC

• For 50-75 HP, FTF or DOC is acceptable. No waiver required

• Devices should be verified by CARB or EPA

Compliance is field verified!

Waivers

• Active regeneration must be considered

• Economic analysis of retrofit cost to equipment value

• Reciprocity (3 years for BAT)

a. Safety/visibility

b. Void the engine warranty

c.  Other mechanical reasons

d. Can’t upgrade Tier 0 to 1

e. Cost: 30 percent of the fair market value of the construction equipment

f. Engineer’s discretion

At the Port Authority, we are committed to a greener tomorrow.

Thank you!
