Current through 2024-29, July 17, 2024
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.
