“EPC” Requirements
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
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
bridges
tunnels
terminals
airports
PATH
Core Requirements
• Idle Restrictions
• Newer Engines
• ULSD
• BAT
ports
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
Agency Wide Clean Diesel Specifications
Applicability:
All land based and barge
mounted diesel powered
construction equipment
(Specifically excludes marine)
Site Implementation:
Contract Book
Location:
Division 1: Diesel Fuel
Immediate, i.e., all equipment
must arrive on site meeting
requirements
Submittal Requirements
•
Excel format preferred initially and for updated inventories
•
Onsite/off site dates
•
Make, manufacturer, model, and serial numbers for:
engine (2) equipment and (3) retrofit

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

Retrofit Verification Programs
PA Accepts Verification From:
1) CARB
http://www.arb.ca.gov/diesel/verdev/vt/cvt.htm
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!
