§ 1956.7. Exhaust Emission Standards and Test Procedures--1981 Through 1986 Model Heavy-Duty Gasoline-Powered Engines and Vehicles and 1981 Through 1984 Model Heavy-Duty Diesel-Powered Engines and Vehicles.
Primary Exhaust Emission Standards(grams per brake horsepower hour)
Gasoline or Diesel Powered
Hydrocarbons Plus Oxides of Nitrogen
* The two sets of standards for each model year are alternatives. A manufacturer has the option for each engine family of showing compliance with either set. Separate deterioration factors shall be established, where applicable, for HC, CO, NOx, and/or the combined emissions of HC and NOx.
The following optional exhaust emission standards are applicable to engines tested pursuant to the optional federal test procedures and regulations for 1984 model heavy-duty engines. These standards replace the federal standards in Code of Federal Regulations Sections 86.084-10 and 86.084-11 for hydrocarbons, carbon monoxide and oxides of nitrogen, only.**
Optional Exhaust Emission Standards(grams per brake horsepower hour)
Oxides of Nitrogen
** The federal 13-mode optional standards for 1984 model-year diesel-powered engines do not apply. In addition, the engine crankcase emission control requirement in Subparagraph 86.084-11(b)(2)(c) shall not apply for the 1984 model year.
(c) The test procedures for determining compliance with standards applicable to 1982 through 1986 models are set forth in the “California Exhaust Emission Standards and Test Procedures for 1982 through 1986 Model Heavy-Duty Gasoline-Powered Engines and Vehicles and 1982 through 1984 Model Heavy-Duty Diesel-Powered Engines and Vehicles,” adopted October 5, 1976, as last amended April 25, 1986.
(e)(1) For 1982 through 1984, the executive officer may authorize use of engines certified to meet federal emission standards, or which are demonstrated to meet appropriate federal emission standards, in up to a total of 100 heavy-duty vehicles in any one calendar year when the executive officer has determined that no engine certified to meet California emission standards exists which is suitable for use in the vehicles. For 1985 and future years, the use of engines which are not heavy-duty engines certified for sale in California may be authorized pursuant to Section 1956.8.
(2) In order to qualify for an exemption, the vehicle manufacturer shall submit, in writing, to the executive officer the justification for such exemption. The exemption request shall show that, due to circumstances beyond the control of the vehicle manufacturer, California certified engines are unavailable for use in the vehicle. The request shall further show that redesign or discontinuation of the vehicle will result in extreme cost penalties and disruption of business. In evaluating a request for an exemption, the executive officer shall consider all relevant factors, including the number of individual vehicles covered by the request and the anti-competitive effect, if any, of granting the request. If a request is denied, the executive officer shall state in writing the reasons for the denial.
(3) In the event the executive officer determines that an applicant may meet the criteria for an exemption under this subsection, but that granting the exemption will, together with previous exemptions granted, result in over 100 vehicles being permitted under this subsection to use non-California engines in heavy-duty vehicles in any one calendar year through 1984, the exemption may be granted only by the state board, under the criteria set forth herein.
