Memphis Code of Ordinances § 11-32-23
in effectSec. 11-32-23. - Emission control devices and emissions generally.
A. Every gasoline-powered vehicle shall not emit carbon monoxide (CO) and/or hydrocarbon (HC) in its exhaust in excess of standards established by the director of the public service division. In setting inspection standards for emission of pollutants, the director of the public service division may use manufacturer's specifications, industry guidelines, and recommendations of the U.S. Environmental Protection Agency. Where required by law, regulation or court order, he or she shall establish inspections to meet the mandated standards, and shall provide for an inspection at least one time per year by the public service division of the city.
B. No person shall remove or cause to be removed any factory-installed device which has as its purpose, or produces the effect of, reducing the emission of pollutants, except when the removal is for the purpose of repair or replacement.
C. No person shall introduce or cause to be introduced into any gas tank of a motor vehicle any fuel or additive which has the effect of directly increasing the emission of pollutants or which will directly or indirectly result in damage to pollution-control devices which were installed by the manufacturer.
D. The director of the public service division may waive any standards and the requirement to make repairs to meet those standards for any group of motor vehicles when, in his or her opinion, the cost of making the required repairs is unreasonable or when it is unlikely that repairs will result in significantly improved performance; however, such waivers shall not adversely affect the overall viability or air pollution control plans or strategies developed by the city for the purpose of attaining and maintaining compliance with ambient air quality standards.
