This document provides an overview of natural gas as a vehicle fuel, fueling options for natural gas vehicles, and factors to consider when purchasing or converting a vehicle to run on natural gas. It discusses the benefits of natural gas including cost savings, domestic supply, reduced emissions, and lower carbon footprint compared to gasoline or diesel. The document outlines the different types of natural gas fueling options including time-fill, fast-fill, and combo-fill. It also provides questions fleet managers should consider when evaluating their fueling needs and options. Finally, the document discusses the process of switching a fleet to natural gas and getting started with planning and evaluation.

3. Natural Gas Basics
Natural Gas
Hydrocarbons, predominantly methane (CH4)
High octane rating
Nontoxic, noncorrosive, and noncarcinogenic
Not a threat to soil, surface water, or groundwater
Lower ozone-forming emissions than gasoline or diesel
Extracted from gas and oil wells
Existing pipeline distribution system
Renewable gas – landfill,dairy farms, wastewater facilities
Odorless – additive added to give it a smell

4. Price protection for the bottom line
• Oil is unpredictable and getting scarce
• Natural gas is cheaper– Saving $$$ to bottom line
Energy independence for America
• 70% of oil is from outside North America
• 33% of oil is from OPEC
• 98% of natural gas is from North America
Cutting air pollution
• Too many regions have unhealthy air
• Natural gas is the cleanest available technology
Reducing carbon footprint
• Fleets are under pressure to reduce GHG emissions
• Natural gas cuts GHG emissions by 25% or more
• 88% reductions with biogas
Local mandates
• To achieve compliance with environmental policy

What’s Driving the switch to CNG?
5. Time-Fill Fueling
• Good for centrally-based fleets with consistent
schedules- Return to base- No staging
• CNG is dispensed slowly, often overnight
• Better fill over a time period- lower heat in
fueling
• Lower cost investment
Fast-Fill Fueling
• Fueling takes place in minutes
• No investment if use public fueling
• Good for vehicles with little downtime
Combo-Fill Fueling
• Time-fill and fast-fill
• More flexibility in fueling
• Back of fence /front of fence

• Honda Civic GX
Medium-Duty NGVs
• Vans and shuttles
• Airports and taxi fleets
Heavy-Duty NGVs
• Refuse haulers
• Transit buses
• School buses
• Long-haul trucks
• Street sweepers

• Short-haul delivery trucks
Where Does CNG Fit In Your Fleet?
7
8. Offsite, Public Access
• Utilize an existing public station
• Operated by retailer, utility, or fleet
• Anchor fleet or pool of multiple fleets
Onsite, Private Access
• Use by fleets
• Time-fill stations typically private access
Onsite, Public Access
(Combo station)
• Often located outside of restricted areas
• Benefit from economy of scale
• Promotes public use of NGVs
• Must have fast-fill capabilities for public
What Are Your Fueling Needs & Options?
8
9. • Evaluate fleet- types of vehicles i.e. cars , pick-up, vans, dump trucks,
garbage trucks, box trucks, tractors….
• How many vehicles will be fueled each day?
• How much fuel will each vehicle need?
• When and how often will vehicles need to be fueled?
• What are the site development requirements?
• What are my routes?
• What are my truck replacement cycles?
• Can I support my own station? Or do I need to utilize Public Fueling?

54. 5454
NGV Inspections
1. When is inspection necessary
(Fuel System Inspection)?:
• ANSI NGV 2 (fuel tank spec)
requires every 3 years.
• TP-304-03 FMVSS (CNG Fuel Container Integrity),
National Highway Traffic Safety Administration requires
additional “or 36,000 miles” for tank inspection.
• NFPA 52 requires that a tank is inspected
• After an accident or fire
• Before it is reinstalled in a vehicle
55. 5555
NGV Inspection (Continued)
2. Who is a qualified inspector?:
• Compressed Gas Association (CGA) defines a qualified
inspector as:
Best Way: Certification from nationally recognized
organization (e.g. CSA – Fuel SYSTEM Inspection)
2 years experience conducting inspections
Supervision by person with 2 years experience conducting
inspections
Approved by fuel cylinder manufacturer
Certification from original equipment manufacturer through
training center
Certification as approved by Authority Having Jurisdiction
56. 5656

address equipment placement and set backs.
o Compression, Storage, and Dispensing Equipment
are addressed in these chapters.
o Location, either indoors and outdoors, of the
equipment matters.

give guides on final equipment placement e.g. tank
separation (from other aboveground fuel tanks &
dispenser).
62. 6262
Electrical Hazardous Area Location
NFPA 30A & NFPA 52 establish electrical area classification for
CNG fueling stations.
oCompressors, Aboveground Storage Tanks, Dispensers,
Pressure Relief Discharge, Vents and ancillary equipment
(dryers) are classified per Table 7.4.2.9 in NFPA 52.
Electrical Conduits and Wiring must be installed per approved
methods indicated in NEC for classified areas.
With AHJ approval, classified areas specified in Table 7.4.2.9 are
permitted to be reduced or eliminated by positive pressure
ventilation from a source of clean air and/or inert gas per NFPA
496.
64. 6464
Safety Valves and Devices
o Storage: Manual shutoff valve and Pressure Relief
Devices installed.
o Dispenser: Breakaway protection provided so fuel
stops if/when “drive aways” occur.
o Station Inlet: Manual shutoff valve should be
installed at gas meter
65. 6565
Emergency Shutdown Device (ESD)
o Manual Emergency Stop buttons are
installed near the dispensing, in the
compressor area, and a safe
distance from the dispensing area.
o When activated the ESD’s should
shut off power and gas supply for
compressor and dispenser.
67. 6767
Got Barriers?
What are the barriers for CNG Station Installations in
Indiana?
What are the barriers for purchasing/converting NGVs
in Indiana?
69. 6969
CNG Fuel
o CNG or Compressed Natural Gas is predominately
Methane (chemical formula CH4).
o It is a nontoxic, colorless, and odorless gas(odorant is
typically added for detection).
o Natural Gas typically exists in a gaseous vapor form.
o Unlike gasoline, diesel, or propane; natural gas is lighter
than air.
o5.66 lbs (~125 SCF) of natural gas is a Gasoline Gallon
Equivalent (GGE)
o 6.312 lbs (~139 SCF) is a Diesel Gallon Equivalent (DGE) –
Proposal to NIST
70. 7070
CNG Fueling Basics
oNominal pressure of CNG fuel systems in the
U.S. have been standardized to 3600 psig. Older
3000 psig systems have largely been phased out.
o CNG fuel tanks are allowed to be filled to 3600
psig at 70° F (settled pressure), and no more than
4500 psig at any temperature.
o Fueling is either stopped by the dispenser when
a temperature compensated full fill pressure is
achieved or manually stopped by operator with a
switch at the dispenser.
71. 7171
Station Installation - General

84. Imports of crude oil to the U.S. were on an upward trend for about 20 years. Since 2006, this trend has reversed,
with imports of crude oil declining to 7.7 million barrels per day by 2013. In 2009 lower demand and a collapse in
oil prices caused the expenditures to fall to about $750 million per day. Since that time the spending has been
closer to $1,000 million per day or more.
