(a) The exhaust emissions from new 1980 model
				  passenger cars, light-duty trucks and medium-duty vehicles, subject to
				  registration and sold and registered in this state, shall not exceed:

"PC" means passenger
							 cars.
"LDT" means light-duty
							 trucks.
"MDV" means medium-duty
							 vehicles.
(2)
Equivalent inertia weights
							 are determined under subparagraph 40 Code of Federal Regulations 86.129-70(a),
							 as it existed on April 15, 1978.
(3)
Hydrocarbon standards in
							 parentheses apply to total hydrocarbons, or 1980 models only, to emissions
							 corrected by a methane content correction factor.
(4)
In addition, for passenger
							 cars, the maximum projected emissions of oxides of nitrogen measured on the
							 federal Highway Fuel Economy Test (HWFET; 40 CFR Part 600 , Subpart B) shall be
							 no greater than 1.33 times the applicable standard shown in the table. Both the
							 projected emissions and the HWFET standard shall be rounded to the nearest 0.1
							 gm/mi before being compared.
(5)
For vehicles from evaporative
							 emission families with projected 50,000 mile evaporative emissions values below
							 1.0 gm/test, an adjustment to the hydrocarbon exhaust emission standard may be
							 granted by the Executive Officer. The adjusted standard will be calculated
							 using the following formula:
HCex = .75 (.185
							 -[(Di + 3.3 Hs) - (29.4)] + HCo
Where:
HCex =
							 adjusted exhaust hydrocarbon standard
HCo =
							 unadjusted exhaust hydrocarbon standard
Di = diurnal evaporative
							 emissions
Hs = hot soak evaporative
							 emission
(b)
				  The test procedures for determining compliance with these standards are set
				  forth in "California Exhaust Emission Standards and Test Procedures for 1980
				  Model Passenger Cars, Light-Duty Trucks, and Medium-Duty Vehicles," adopted by
				  the State Board on May 24, 1978, as last amended March 5, 1980.
(c) With respect to any new vehicle required
				  to comply with the standards set forth in paragraph (a), the manufacturer's
				  written maintenance instructions for in-use vehicles shall not require
				  scheduled maintenance more frequently than or beyond the scope of maintenance
				  permitted under the test procedures referenced in paragraph (b) above. Any
				  failure to perform scheduled maintenance shall not excuse an emissions
				  violation unless the failure is related to or causative of the
				  violation.
(d) This regulation
				  shall remain in effect until December 31, 1990, and as of that date is repealed
				  unless a later regulation deletes or extends that date. Notwithstanding the
				  repeal or expiration of this regulation on December 31, 1990, the provisions of
				  the regulation as they existed prior to such repeal or expiration shall
				  continue to be operative and effective for those events occurring prior to the
				  repeal or expiration.
