5 CCR 1001-13 - REGULATION NUMBER 11 MOTOR VEHICLE EMISSIONS INSPECTION PROGRAM
Part C - Inspection Procedures and Requirements for Exhaust Emissions, Fuel Evaporation Control, Visible Smoke Emissions, Emissions Control Systems, On-Board Diagnostics (OBD); and Practices to Ensure Proper Emissions Related Adjustments and Repairs
Section X - EMISSIONS RELATED REPAIRS
Current through Register Vol. 48, No. 6, March 25, 2025
X.A. Emissions related repairs include only those adjustments to and maintenance and repair of the motor vehicle that are directly related to the reduction of exhaust emissions and/or undertaking repairs that extinguish the OBD Malfunction Indicator Light (MIL) necessary to comply with the applicable emissions limits and procedures. The expenditure for emissions related repairs does not include the inspection fee as specified in Section 42-4-311, C.R.S. or expenses associated with the adjustments to and maintenance, replacement, and repair of air pollution control equipment on the vehicle if the need for such adjustment, maintenance, or repair pursuant to Part C, Section III is due to disconnection of, tampering with, or abuse to such air pollution control equipment. Air pollution control equipment is any part, assembly or system originally installed by the manufacturer for the sole or primary purpose of reducing emissions.
X.B. Repairs and maintenance to the following systems shall qualify as emissions related repairs insofar as the purpose is to reduce exhaust emissions or extinguish the OBD MIL:
- Air Intake Systems
- Ignition Systems
- Fuel Control Systems
- Emissions Control Systems
- Basic Engine Systems
- Microprocessor (02) based air/fuel control systems.
X.C. If the vehicle continues to exceed applicable emissions limit, or continues to fail OBD, the vehicle must undergo specific emissions related repairs. Adjustments and repairs must be accomplished to the point of compliance, or the applicable repair cost ceiling has been met. If the applicable emissions related adjustment and repair requirements have been met, the vehicle owner may be referred to a Department of Revenue Motor Vehicle Emissions Compliance Inspector to receive a waiver. Repairs must have been reasonably calculated to achieve a reduction in emissions of those components of the inspection that the vehicle failed, pursuant to manufacturer's specifications as required by 42-4-306 (7)(a)(II)(A) and 42-9-111 C.R.S.
In order to be creditable to the enhanced repair cost limits, adjustments and repairs must have been performed by a repair facility/technician registered with the Division pursuant to Part D of this regulation. Only the appropriate emissions failure related parts costs should apply to applicable waiver limits for repairs not performed at a licensed emissions inspection station or registered repair facility/technician.
