1. Clean Diesel Construction Requirements of the Port Authority of NY & NJ
Dorian Bailey, Supervisor Chemical/Environmental Testing Engineering Department

2. Rebuilding of the World Trade Center
Environmental Performance Commitments
“EPC” Requirements
Submit a Diesel Engine Emission Mitigation Plan
Follow Diesel Engine Anti-Idling Policy
Use Ultra Low Sulfur Diesel (ULSD) Fuel
Meet or Surpass Diesel Construction Equipment Age Requirements (Tier 2)
Install Best Available Technology on > 50 HP

3. New York City Local Law 77 “LL77” Requirements
Use Ultra Low Sulfur Diesel (ULSD) Fuel
Consider nitrogen oxides and particulate matter strategies
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

4. Agency Wide Clean Diesel Specifications
bridges
tunnels
terminals
airports
PATH
ports
Core Requirements
Idle Restrictions
ULSD
Newer Engines
BAT

5. Agency Wide Clean Diesel Specifications
Clean Diesel Specification Phase in Period
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

6. 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

7. 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
Equipment
Engine
Retrofit
Anticipated function, days and hours
Model year, Tier Rating, HP
Installation dates
Duration of use on project
Fuel consumption per shift
Prior waivers or BAT determinations

8. Diesel 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 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.

9. 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

10. Newer Engines (Tier Levels)
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
Preliminary EIS modeling for the Goethals Bridge Replacement Project shows a possible need for Tier 2 Engines with BAT

11. Best 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)

12. 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:

13. 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
Source:

14. Diesel Particulate Filter
BAT “Gold Standard” for PM
• PM Removal Efficiencies (>90%)
Active or passive filter media regeneration
Active regeneration must be considered for higher HP applications with low exhaust temps
Figure 2:

15. Retrofit Verification Programs
PA Accepts Verification From:
CARB
EPA
VERT/BUWAL

16. Compliance is field verified!
BAT Summary
General PM Removal %:
DPF > FTF > DOC
For HP, FTF or DOC is acceptable. No waiver required
Devices should be verified by CARB or EPA
Compliance is field verified!

17. 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
Cost: 30 percent of the fair market value of the construction equipment
Engineer’s discretion
