  Sec. 217-1.3. Motor vehicle exhaust emission standards and inspection procedure  

Latest version.
  • (a) In accordance with the applicability set forth in section 217-1.2 of this Subpart, no person who owns, operates, or leases a nonelectric or nondiesel powered motor vehicle subject to the requirements of this section shall operate said vehicle, or allow or permit it to be operated, in such a manner that:
    (1) it emits carbon monoxide (CO), oxides of nitrogen (NOx), or hydrocarbons (HC) in the exhaust in excess of standards specified in tables 1a and 1b; or
    (2) for gasoline powered motor vehicles only, the gas cap fails to meet the minimum standard contained in table 2 of this Subpart; or
    (3) for model year 1996 and newer motor vehicles, the on-board diagnostic system:
    (i) fails to function as designed; or
    (ii) fails to complete diagnostic routines for necessary supported emission control systems; or
    (iii) indicates that the malfunction indicator light fails to illuminate at the starter switch key-on-engine-off position; or
    (iv) the malfunction indicator light is illuminated when the engine is running; or
    (v) the malfunction indicator light is commanded to be illuminated; or
    (4) the combined carbon monoxide (CO) and carbon dioxide (CO2) emission from the vehicle tailpipe is less than 6.0 percent.
    (b) In accordance with the applicability set forth in section 217-1.2 of this Subpart, any person who owns, operates, or leases a nonelectric or nondiesel powered motor vehicle subject to the requirements of this section shall have adjustments, repairs, or replacements made to said vehicle to ensure that the requirements of subdivision (a) of this section are met unless an emission inspection waiver is issued by the Department of Motor Vehicles pursuant to section 79.25 of 15 NYCRR Part 79.
    (c) In accordance with the applicability set forth in section 217-1.2 of this Subpart, no person who owns, operates, or leases a nonelectric or nondiesel powered motor vehicle subject to the requirements of this section shall operate said vehicle, or allow or permit it to be operated, in such a manner that:
    (1) for gasoline powered vehicles, the gas cap fails to meet the minimum standard contained in table 2; or
    (2) for model year 1996 and newer motor vehicles, the on-board diagnostic system:
    (i) fails to function as designed; or
    (ii) fails to complete diagnostic routines for necessary supported emission control systems; or
    (iii) indicates that the malfunction indicator light fails to illuminate at the starter switch key-on-engine-off position; or
    (iv) the malfunction indicator light is illuminated when the engine is running; or
    (v) the malfunction indicator light is commanded to be illuminated.

    *Actual exhaust emission standards shall be set by the department during the start-up phase (a period of up to two years) from the range presented. Initially, these standards will be those recommended by the USEPA as contained in table 1a in bold print (most stringent). Standards listed are based upon the IM240 test. Other test methods may be used but cutpoints used for other tests will be set to yield the same failures as would be realized using the IM240 test. Standards may be changed within the range for each model year if repair facilities experience significant problems in repairing failed vehicles to meet standards or if actual failure rates vary substantially from those predicted. The department reserves the right to set adjustment factors for nongasoline or nondiesel fueled vehicles. The department shall publish notice of any changes to the standards in the Environmental Notice Bulletin.
