Gas Cap Testing
|
Since a missing or leaking gas cap can cost motorists approximately
$35 per year in lost gasoline (through evaporation), gas cap testing
is designed to make sure the caps "hold in" the correct amount of
pressure, ensuring that gasoline vapors are not escaping into the
atmosphere and contributing to our smog problem. |

Ground-level Ozone
|
Ground-level
ozone is formed through chemical reactions between natural
and man-made emissions of volatile organic compounds (VOCs)
and nitrogen oxides (NOx) in the presence of sunlight.
These gaseous compounds mix in the air, and when they
interact with sunlight, ground-level ozone is formed.
Sources of these pollutants include automobiles,
gas-powered mowers, refineries, chemical manufacturing
plants, solvents used in dry cleaners and paint shops, and
wherever natural gas, gasoline, diesel fuel, kerosene, and
oil are used as fuel.
Ground-level ozone can inflame breathing passages,
decreasing the lung's working capacity. Symptoms can
include shortness of breath, pain when inhaling deeply,
wheezing, and coughing. Ground-level ozone can cause
eye and nose irritation, aggravates respiratory symptoms,
and further impairs the ability to perform normal
activities. It can dry out the protective membranes
of the nose and throat and interfere with the body's
ability to fight infection, which increases susceptibility
to illness. |

Home Energy Audit
|
A home energy audit checks:
general condition of air conditioning and heating systems,
level and condition of insulation, degree of outside air
infiltration, and the operation and condition of lighting,
water heating and other appliances. |
Hybrid Vehicle
|
Any vehicle is hybrid when it combines two or more sources
of power that can directly or indirectly provide propulsion power.
In fact, many people have probably owned a hybrid vehicle at some
point. For example, a mo-ped (a motorized pedal bike) is a type of hybrid
because it combines the power of a gasoline engine with the pedal power
of its rider.

I/M
|
Inspection and Maintenance checks whether the emission control
system on a vehicle is working correctly. All new passenger
cars and trucks sold in the United states today must meet strict pollution
standards, but if the emission controls and engine are not functioning
properly, they cannot maintain a low-pollution profile. I/M is
designed to ensure that vehicles stay clean in actual customer use. Through
periodic vehicle checks and required repairs for vehicles that fail
the test, I/M encourages proper vehicle maintenance. |
Infrastructure

Everything
except the vehicle itself that is necessary for the
utilization of alternative fuel vehicles, including:
available fuel when and where required, access to parts,
competent and capable maintenance and service facilities,
acceptable trade-in and resale market. Source:

Inherently Low Emission Vehicle (ILEV)
|
This is a federal standard only. Such a
vehicle meets EPA, CFV, ILEV exhaust emission standard and
produces very few or no evaporative emissions (5 grams or
less per test without using auxiliary emission control
devices). I KEVS are dedicated AFVs in most cases.
Dual-fueled vehicles will be considered ILEVs only if both
fuels meet the standard. ILEV credits can be banked in the
Consolidated Metropolitan Statistical Area. Source:

Low Income Vehicle Repair Assistance, Retrofit, and
Accelerated Vehicle Retirement Program (LIRAP)
|
The Low Income Vehicle Repair Assistance, Retrofit, and
Accelerated Vehicle Retirement Program (LIRAP) will only apply to
counties that implement a vehicle inspection and maintenance (I/M)
program and have elected to implement LIRAP provisions.
