A dedicated phone service with dial-up back up is required to facilitate operation of the data-communications system.
I.D.	Upon a physical verification of the vehicle identification number (VIN) and license plate number, the emissions mechanic or emissions inspector will enter this information into the program database in order to match this information with the state registration record. In the case of a match, the emissions mechanic or emissions inspector shall proceed. If no match is found, a new inspection record will be created. All non-Colorado registered vehicles and first time registrations with the State of Colorado will require the creation of a new inspection record by the emissions mechanic or emissions inspector.
I.E.	The emissions mechanic or emissions inspector shall ascertain from the inspection record data base if an initial inspection or an after-repairs inspection is to be conducted. If an after-repairs inspection is to be conducted, previous inspection data is required for comparison. Specific emissions related repair information as specified in Section VII (B) of this Part C shall be entered to the database. Inspections conducted within 60 days of the initial inspection date are to be considered an after-repairs inspection. Inspections conducted greater than 60 days from the initial inspection date are to be considered initial inspections. The emissions mechanic or emissions inspector shall accurately enter vehicle, and last inspection information as required for vehicle emissions inspection records.
I.F.	The emissions mechanic or emissions inspector shall perform a cursory safety assessment of the motor vehicle prior to inspection. If in the opinion of the emissions mechanic or emissions inspector the vehicle is unsafe to inspect due to engine/drive-line metallic noises, or leaking fluids, the request for inspection may be refused.
II.	EXHAUST EMISSIONS INSPECTION PROCEDURES
II.A.	All model year vehicles to be inspected at licensed emissions inspection stations within the basic program area and at inspection-only facilities in the enhanced program area shall be administered an EPA approved idle short test as specified in 40 CER, Part 51, Subpart S, Appendix B.
The emissions mechanic or emissions inspector will use a certified TAS to select the appropriate idle short test cycle based upon the make, model year engine family and vehicle classification. These idle short tests include, but may not be limited to, a standard single speed idle test; the pre-idle 30-second pre-conditioning idle test with the high speed (2500 ± 300 RPM) pre-conditioning cycle before the idle mode; a standard two speed (3 - mode) idle test with the raised idle segment at 2500 ± 300 RPM; second chance raised idle pre-conditioning for 30 seconds just prior to the idle mode after an initial failure, and second chance restart in which the ignition is turned off for ten (10) seconds and then restarted to complete the emissions inspection procedure. All sampling modes shall (each) be thirty seconds in duration and raised engine speed modes be it for pre-conditioning or sampling, shall be 2500 RPM ± 300 RPM. As a pass/fail determination, the vehicle's emissions levels must be the same as or less than applicable limits at the designated engine speed(s) in order to pass.
II.B.	The entire vehicle shall be in normal operating condition and at normal operating temperature, which shall be determined by carefully feeling the top radiator hose while the engine is not operating, by checking the temperature gauge, and/or operating the vehicle prior to performing the idle emissions inspection. Vehicles are not to be idled for extended periods of time but rather inspected in an expeditious manner as soon as normal operating temperature is achieved. The vehicle shall be inspected in an as-received condition.

II.B.1.	The analyzer probe shall be inserted at least twelve (12) inches or as recommended by the analyzer manufacturer for a quality sample whichever is greater.
II.B.2.	For all vehicles equipped with a multiple exhaust system, the analyzer's dual exhaust procedure must be used.
II.B.3.	If a baffle or screen prevents probe insertion to an adequate depth, a suitable probe adapter or snug fitting hose that effectively lengthens the exhaust pipe may be used.
II.B.4.	The appropriate emissions limits specified in Part F of this regulation would be utilized by the certified test analyzer system. In selecting appropriate emissions limits, for motor vehicles of model years 1978 and earlier having a gross vehicle weight (GVW) rating of greater than 6000 Ibs., or of model years 1979 and newer having a gross vehicle weight rating of greater than 8500 Ibs.: the emissions mechanic or emissions inspector shall identify that particular vehicle's GVW rating by examining the vehicle information (metal) plate or sticker. These motor vehicles will be subject to the applicable emissions limits as listed in Part F of this regulation. If the vehicle information plate or sticker is missing, illegible or the GVW rating information is not otherwise available, the emissions mechanic or emissions inspector shall examine the engine exhaust emissions control information label which is permanently affixed to the engine and determine heavy-duty engine/vehicle federal certification status. Vehicle engines not labeled as having complied with applicable U.S. EPA heavy-duty regulations by the manufacturer are assumed to be light-duty vehicles and subject to the emissions limits listed in Part F of this regulation. Emissions limits for vehicles in which the engine has been changed shall be based upon whichever is newest, the vehicle or the replacement engine, as specified on a vehicle evaluation form (DR2365) or bar coded label generated by emissions technical center staff or designee.
II.C.	In the event the tachometer over-ride mode must be utilized to inspect a vehicle, an accurate auxiliary tachometer must be used to verify engine speeds mandated in Subpart A of this section.
II.D.	The vehicle will be evaluated for the presence of visible smoke emissions. The evaluation is to be performed during all (engine) operating conditions of the inspection procedures prescribed in Subparts A through G of this Section II.
II.E.	A Certification of Emissions Compliance shall be issued if the vehicle passes the emissions control systems inspection (for 1975 and newer model year vehicles only), the exhaust and evaporative emissions inspection, and there is no evidence of visible smoke emissions.
II.F.	If the vehicle fails the initial emissions inspection the owner is to have appropriate emissions related repairs or adjustments made and may return the vehicle to an AIR Program station, facility or center, as appropriate, for reinspection. Within ten (10) calendar days of the initial test, one free reinspection shall be provided to the motorist if the vehicle is returned to the same station or facility at which the initial test was performed. A motorist shall be entitled to one free after-repairs test at any contractor operated center within ten (10) calendar days of the initial test performed at a contractor operated center. If during repairs, it is determined the necessary parts are not available, the motorist may be issued a temporary Certificate of Emissions Control by Department of Revenue personnel. Proof of part(s) non-availability as described in Subpart III.E. of this part is required. Motorists pursuing a temporary Certificate of Emissions Control must facilitate final vehicle inspection and compliance with adopted regulation.
II.G.	Model year 1982 and newer light-duty vehicles to be inspected at licensed enhanced inspection centers within the enhanced program area shall be administered an EPA approved transient loaded mode inspection procedure as specified in 40 CFR, Part 51 Subpart S Federal Register Volume 57, Number 215, November 5,1992.
II.G.1.	Vehicles shall be inspected in an as-received condition.

II.G.6.	The inspector may refuse to conduct the transient driving cycle dynamometer inspection procedure if the tires on the drive wheels are worn such that the cords are visible or sidewalls are peeling or blistered.
III.	EMISSIONS CONTROL SYSTEMS INSPECTION PROCEDURES

Motor vehicles shall be configured as required for sale or use within the United States pursuant to 40 CFR, Part 86, Subpart A; unless specific documentation in the form of a state issued vehicle evaluation form (DR2365) or an EPA (EPA form 3520) or DOT exemption is submitted.  To ensure compliance with this requirement, the emissions mechanic or emissions inspector shall inspect all model year 1975 and newer vehicles and assess the integrity of the emissions control system in accordance with the procedures set forth in this Section III.
III.A.	Except as provided in Subsection III.B. below, all model year 1975 and newer vehicles shall be visually inspected for the presence and operability of the air system, catalytic converter system(s) and oxygen (O2) systems.  If these parts or systems are not operating as designed, inoperable or has been removed or otherwise tampered with, the vehicle will not qualify for a Certification of Emissions Control.  In assessing whether the proper emissions control systems are present, the emissions mechanic or emissions inspector shall examine the emissions control information decal within the engine compartment to determine the appropriate emissions control systems for that particular vehicle.  If an emissions control information decal is missing, incomplete, illegible or is not appropriate for the specific vehicle, the emissions mechanic or inspector may contact a state emissions technical center for guidance, use other reference materials or refer the vehicle to a state emissions technical center for further evaluation.
III.B.	In place of the visual inspection, the emissions control systems for model year 1996 and newer vehicles may be inspected using the vehicles’ on-board diagnostic (OBD) systems.  To utilize this alternative inspection procedure, the emissions inspector must interrogate the vehicle’s OBD system using Division approved procedures and equipment.  If the emissions inspector is unable to interrogate the OBD system, or if the interrogation reveals either that the malfunction indicator light (MIL) is commanded on or that any OBD monitors are not set, the vehicle shall be visually inspected in accordance with the procedures set forth in Subsection III.A. above.
III.C.	Assessment of System Malfunction/Service Indicators
An assessment of the emissions control system malfunction/service-maintenance indicator(s) performance shall be conducted by the emissions mechanic or emissions inspector on those vehicles so equipped.
For those vehicles equipped with “check engine” dash indicator lights or similar emissions control systems malfunction or service-maintenance indicator(s), the following procedure if applicable will be performed to assess the integrity of the system:
● Ignition Off, Engine Off = indicator(s) off
● Ignition On, Engine Off = indicator(s) on or displayed
● Ignition On, Engine Running = indicator(s) off
The revisions to the malfunction indicator light emissions test criteria contained in Section III.C. and adopted by the Commission on October 17, 2002 shall take effect on April 1, 2003. Thereafter, the failure of the system to respond as described above shall be reported to the motorist, but shall not be used to fail the vehicle.
Light-duty vehicles to include light-duty trucks of model year 1996 and newer equipped with California on-board diagnostic (OBDII) or EPA on-board diagnostic systems (EPA, OBD) shall be evaluated to determine operability and integrity of the applicable system(s). The OBD system will be connected to the TAS and interrogated. Fault codes and diagnostics shall be reported to the motorist with other emissions inspection information but shall not be used to fail the vehicle.
III.D.	The repair/replacement of catalytic converters must incorporate the same type, style and location on the exhaust system relative to engine as originally designed by the vehicle manufacturer. If a new original equipment manufacturer (OEM) part is not used, only an EPA “accepted” after-market component appropriate to that application may be used. Verification of the correct application and certification status must be performed at the time of reinspection. The submittal and review of repair receipts as specified in Subsection VII.B of this section is required in order to substantiate proper repairs of applicable emissions control system.
III.E.	If the necessary part(s) will not be available prior to the month of expiration of the present vehicle registration, and the owner obtains a signed form or statement to that effect from a manufacturer's dealer for that make vehicle, or from an automotive parts supplier which in the normal course of business supplies part(s) for that vehicle, Department of Revenue personnel after verification may issue a temporary Certification of Emissions Control. The form or statement provided must specifically identify by part numbers and description, the necessary part(s). The owner then has until the expiration of the temporary certification to complete the necessary repairs or replacement.
IV.	EVAPORATIVE FUEL CONTROL INSPECTION PROCEDURES
Model year 1975 and newer vehicles shall be inspected for the presence and integrity of the gasoline cap(s). The gasoline cap(s) of such vehicles inspected in the six county metro Denver enhanced program area as defined in Section 42-4-304(9)(a)., shall also be inspected for sealing integrity as specified in Part F (IV) of this regulation.
Vehicles with a missing gasoline cap(s) shall not qualify for issuance of a Certificate of Emissions Control. Motorists whose vehicles have gasoline cap(s) demonstrating excessive leakage shall be notified of the deficiency, repair/replacement shall be voluntary. Repair/replacement of defective cap(s) shall be required on and after January 1,1999. The gas cap sealing integrity procedure shall be effective January 1,1998.
V.	<Reserved>
VI.	FREE REINSPECTION
Vehicles which fail any or all elements of an emissions inspection are eligible for one free reinspection within ten (10) calendar days if presented to the same station or facility as initially inspected and failed. In the case of the contractor operated enhanced inspection center network, the ten (10) day free reinspection shall be honored at any enhanced inspection center.

IX.	Repeal
This Part G shall be repealed effective July 1, 2010. 
PART H	Statements of Basis, Specific Statutory Authority and Purpose
XXII.	AMENDMENTS ADOPTED OCTOBER 16, 2008
Basis and Purpose
The purpose of this rulemaking is to implement revised visual inspection procedures and methodology for 1996 and newer model year vehicles.  It is expected that this rule revision will result in improved inspection throughput, resulting in shorter vehicle wait times and improved motorist convenience.  Another purpose of this revision is to delete obsolete language and correct minor typographic errors.
The effect of the rule change is to shorten the amount of time it takes to inspect vehicles for exhaust and gas cap evaporative emissions.  
Currently the state receives no sip credit from visual inspecting 1996 and newer vehicles.  Therefore, this rule change will result in no sip credit loss.  Vehicles that would be expected to fail the visual component of the IM inspection will continue to be detected through interrogation of the MIL command and OBD system.
Another pupose of this reulemaking is to eliminate certain no longer relevant components of the regulation, concerning chlorofluorocarbons and motor vehicle filler-neck inspections.  These inspections have become obsolete, and no longer serve a purpose.  Chlorofluorocarbons have been outlawed for a number of years now.  The filler-neck restriction was to prevent the use of leaded gasoline in unleaded fueled vehicles.  Leaded gasoline use in on-highway motor vehicles has been banned since 1993.
Specific Statutory Authority
The Commission promulgates these regulatory changes pursuant to its authority to authority to set emissions inspection requirements and procedures as provided by section 42-4-306(a), C.R.S.  Additional authority is set forth in section 42-4-306(1), C.R.S., which gives the Commission the authority to adopt regulations as may be necessary to implement the emissions testing program. 
Scientific/Technical Rationale
The rule is based on reasonably available, validated, reviewed, and sound scientific methodologies.  This rule change will bring the visual inspection component in line with current EPA guidance and requirements and the practices of other states.  The regulatory change will maximize the air quality benefits from the AIR Program, while improving motorist convenience in a cost-effective manner.
