A.
Certified inspector.
"Certified inspector" means a Department of Environmental Protection
employee or person designated by the Department as an inspector who is
certified pursuant to the procedures for certification specified in 40 Code of
Federal Regulations, Part 60, Appendix A, Method 9.
B.
Compliance. "Compliance"
means meeting the emission opacity standards for diesel-powered motor vehicles
as established by the Board of Environmental Protection.
C.
Diesel emissions. "Diesel
emissions" means diesel smoke that is emitted into the environment from any
diesel-powered motor vehicle.
D.
Diesel emissions inspection report or inspection report. "Diesel
emissions inspection report or inspection report" means a document issued by a
certified inspector at the time of inspection, in such form as the Commissioner
shall prescribe, containing a designation of pass or fail, which shall
constitute proof of inspection.
E.
Diesel-powered motor vehicle. "Diesel-powered motor vehicle" means
those diesel-powered motor vehicles that have a gross vehicle weight rating of
18,000 or more pounds. Diesel-powered motor vehicle does not include a truck
registered as a farm truck.
F.
Diesel smoke. "Diesel smoke" means particles, including aerosols,
suspended in the exhaust stream of a diesel engine which absorb, reflect, or
refract light.
G.
Emission
opacity standards. "Emission opacity standards" means the acceptable
level of peak smoke opacity for diesel-powered motor vehicles as established by
the Board of Environmental Protection.
H.
Emissions related repairs.
"Emissions related repairs" means any emissions repair intended to bring
a diesel-powered motor vehicle, which has received a fail designation during an
inspection, into compliance with the established emission opacity
standards.
I.
Fail
designation. "Fail designation" means a designation on an inspection
report which signifies that the diesel-powered motor vehicle does not meet the
emission opacity standards.
J.
Governor. "Governor" means a mechanism installed on a diesel
engine by the original equipment manufacturer for the purpose of limiting the
maximum engine RPM.
K.
Inspection. "Inspection" means a snap-acceleration smoke opacity test
conducted by a certified inspector in accordance with the Society of Automotive
Engineers (SAE) J1667 Recommended Practice, and related administrative
procedures.
L.
Model year.
"Model year" means the year designated by the manufacturer of the
diesel-powered motor vehicle and appearing on the registration
certificate.
M.
Opacity.
"Opacity" means the degree of light-obscuring capability of emissions of
visible air contaminants expressed as a percentage. For example, complete
obscuration shall be expressed as 100% opacity.
N.
Operator. "Operator" means
the person operating the vehicle during a diesel-powered motor vehicle
emissions roadside test.
O.
Pass designation. "Pass designation" means a designation on an
inspection report which signifies that the diesel-powered motor vehicle meets
the emission opacity standards.
P.
Peak smoke opacity. "Peak smoke opacity" means the highest
numerical value of smoke opacity obtained through the testing procedures for
the snap-acceleration smoke opacity test.
Q.
SAE. "SAE" means the Society
of Automotive Engineers.
R.
SAE J1667. "SAE J1667" means the Surface Vehicle Recommended
Practice incorporated in document number J1667 published by the Society of
Automotive Engineers in February 1996, entitled "Snap-Acceleration Smoke Test
Procedure for Heavy Duty Diesel Powered Vehicles", as herein incorporated by
reference.
S.
Snap-acceleration smoke opacity test. "Snap-acceleration smoke opacity
test" means a test adopted by the Society of Automotive Engineers for the
testing of diesel-powered motor vehicles. This test is commonly referred to as
the SAE J1667 Recommended Practice Test. The test includes five phases: vehicle
preparation; test preparation and equipment set-up; driver familiarization and
vehicle preconditioning; execution of the snap-acceleration test; and
calculation and reporting of final results.
