10.58.010 Visible emissions from diesel-powered motor vehicles unlawful.
A. No owner or operator of a diesel-powered vehicle shall cause or knowingly permit the emission from such vehicle of any visible air contaminants which exceed the emission level as described in Section 42-4-412(2)(a), C.R.S.
B. Any owner or operator of a diesel-powered motor vehicle receiving a summons and complaint issued pursuant to subsection A of this section shall secure a certification of opacity compliance from a state emissions technical center that such vehicle conforms to the requirements of this section. Said certification shall be returned to the owner or operator for presentation in court as provided in subsection C of this section.
C. Any owner who violates any provision of this section is guilty of a Class 4 traffic offense and, upon conviction thereof, except as provided in subdivision (1) or (2) of this subsection, shall be punished by a fine of one hundred dollars.

If the operator submits to the municipal court within fifteen days after the issuance of the summons proof that he was not the owner of the vehicle at the time the summons was issued and that he mailed, within five days after issuance thereof, a copy of the notice and summons by certified mail to the owner of the vehicle at the address on the registration, he shall be punished by a fine of twenty-five dollars.
2. Upon a showing of good cause that compliance with this section cannot be made within fifteen days after issuance of the summons and complaint, the municipal court may extend the period of time for compliance as may appear justified.
E. Violations of this section may be determined by visual observations of a police agent who is certified by the Department of Health as trained to ascertain violations of such standards without reference to opacity levels and to distinguish between air contaminants, and steam or water vapor.
F. The provisions of this section shall not apply to emissions caused by cold engine start-up. (Ord. O-97-62 § 43, 1997; Ord. O-87-87 § 7, 1987; Ord. O-80-19 § 1 (part), 1980).

10.58.020 Air pollution violations.
A. It is unlawful for any person to drive or for the owner to cause or knowingly permit to be driven any motor vehicle, powered by gasoline or any fuel except diesel, which emits any visible air contaminants.
B. The provisions of this section shall not apply to motor vehicles empowered by diesel engines or to emissions caused by cold-engine start-ups.
C. Violations of this section may be determined by visual observations or by test procedures using opacity measurements.
D. Any person who violates any provision of this section is guilty of a Class 4 traffic offense, and upon conviction thereof, except as provided in subdivision (1) or subdivision (2) of this subsection, shall be punished by a fine of twenty-five dollars. For subsequent offenses, the fine is one hundred dollars.
1. If the owner presents to the municipal court an affidavit that the vehicle has been disposed of in such a manner that it will no longer be operated on the highways, together with the registration card and license plates of such vehicle, the fine shall be suspended.
2. Upon presentation of an affidavit of the owner that such vehicle has been repaired prior to the date set for appearance upon the charge, which appearance date shall be at least fifteen days after the alleged offense, stating the date, location, and nature of repairs made, together with the name of the person making said repairs, and that the vehicle is not in violation of the provisions of this section when in normal operation, the fine shall be suspended.

10.58.030 Definitions.
The following definitions shall apply in the interpretation and enforcement of this chapter:
"Air contaminant" or "air pollution" means any fumes, smoke, particulate matter, vapor, or gas or any combination thereof which is emitted into or otherwise enters the atmosphere, including, but not limited to, any physical, chemical, biological, radioactive (including source material, special nuclear material, and by-product material) substance or matter, but "air pollutant" does not include a water vapor or steam condensate.
"Emission" or "emit" means a discharge or release of one or more air contaminants into the atmosphere.
"Opacity" means the degree to which an air contaminant emission obscures the view of a trained observer, expressed in percentage of the obscuration or the percentage to which transmittance of light is reduced by an air contaminant emission. (Ord. O-87-87 § 9, 1987; Ord. O-80-19 § 1 (part), 1980).
