5 Colo. Code Regs. § 1001-15-D-VI
Adopted November 16, 2006
Basis and Purpose
Regulation Number 12 establishes as a control strategy, the Diesel Opacity Inspection and the Diesel Fleet Self-Certification Programs. Both programs require periodic inspection of both light-duty and heavy-duty diesel powered vehicles. Emissions related repairs are required of those vehicles that do not comply with inspection requirements. The intended purpose of Regulation Number 12 is to reduce diesel vehicle emissions.
The rule revision implements provisions of Section 42-4-406 C.R.S. as amended pursuant to S.B. 06-058, as follows:
* Light-duty diesel test cycles are extended to two years for models 10 years old or newer and model year 2004 and newer,
* Extend the light-duty model year exemption from two years to four years,
* Remove obsolescent language which changes are not substantive.
The changes were adopted to implement statutory changes and the Commission has no discretion but to adopt the provisions of S.B. 06-058. The rule provides regulatory relief and is not intended to reduce air pollution.
Statutory Authority
Specific statutory authority for amendments to Regulation Number 12 is set out in Sections 42-4-403 and 42-4-414, C.R.S.
Findings pursuant to Î3/4 25-7-110.8
The rule revisions are exempt from the determinations required by Î3/4 25-7-110.8 C.R.S. because the changes were adopted to implement statutory provisions and remove an obsolete provision rather than reduce air pollution. The regulatory revisions relax existing inspections for diesel vehicles and the Commission has no discretion but to adopt them under state law.
Further, these revisions will include any typographical and grammatical errors throughout the regulation.
